PURPOSE: To describe usual dietary intake assessment at baseline and 1-year post-randomization in the ethnically diverse Diabetes Prevention Program cohort. METHODS: Participants were randomized to Lifestyle Modification, Metformin, or Placebo. Usual diet was assessed by a modified, previously validated food frequency interview. RESULTS: Complete data were available for 2934 subjects (90.7% of those randomized). Baseline median estimated energy intake was 7676 kJ/d (1828 kcal/d) and 8585 kJ/d (2044 kcal/d) for women and men, respectively. The median percent of energy from fat ranged from 30.6% for Asian American men to 37.5% for American Indian men and women. After 1 year among the Lifestyle group, the median change in total energy and percent energy from fat was -1897 kJ/d (-452 kcal/d) and -6.6%, respectively. For the Metformin and Placebo groups, change in median total energy was -1235 kJ/d (-294 kcal/d) and-1051 kJ/d (-250 kcal/d), respectively, and change in median percent energy from fat was -0.8% and-0.8%, respectively (p < 0.001 for differences between groups, adjusted for gender and ethnicity). CONCLUSIONS: One-year post-randomization, significant differences in dietary intake were observed in the Lifestyle compared with the Metformin or Placebo group, and these were consistent with the general intent of the DPP lifestyle modification intervention. 相似文献

BackgroundLow-calorie sweetened beverages (LCSBs) are commonly used as a lower-calorie alternative to sugar-sweetened beverages (SSBs) by individuals with type 2 diabetes. However, little is known about how intake of LCSBs is related to dietary intake and cardiometabolic health, particularly among youth.ObjectiveTo test the hypothesis that having higher baseline LCSB intake and increasing LCSB intake over 2 years of follow-up are associated with poorer dietary intake and higher cardiometabolic risk factors among youth enrolled in the Treatment Option for Type 2 Diabetes in Adolescents and Youth (TODAY) study.DesignSecondary, exploratory, analysis of baseline and longitudinal data from the TODAY study, which was a randomized, multisite trial conducted from 2004 to 2012, to compare effects of 3 interventions (metformin alone, metformin + rosiglitazone, and metformin + intensive lifestyle intervention) on glycemic control in youth with type 2 diabetes.Participants/settingThe study included 476 children and adolescents (10-17 years, mean body mass index 34.9 ± 7.8 kg/m2), who were participants in the multicenter (n = 15) TODAY study.Main outcome measuresDiet was assessed using a food frequency questionnaire. Differences in energy intake, macronutrients, food group intakes, and cardiometabolic biomarkers were evaluated in 3 groups of LCSB consumers at baseline (low [1-4 servings/wk], medium [5-11 servings/wk], and high [≥12 servings/wk]), each compared with nonconsumers, and between 4 groups of change in LCSB intake (nonconsumption at start of study and nonconsumption after 2 years, increase in consumption after 2 years, decrease in consumption after 2 years, and high consumption at start of study and high consumption after 2 years).Statistical analyses performedMultivariable linear regression was performed at baseline and longitudinally over 2 years of follow-up.ResultsEnergy (kilocalories), fiber, carbohydrate, total fat, saturated fat, and protein intake (grams) were higher among high LCSB consumers compared with nonconsumers at baseline. No associations were observed between LCSB consumption and cardiometabolic risk factors at baseline. Change in LCSB intake between baseline and follow-up was not associated with change in energy intake or cardiometabolic risk factors. Participants who decreased LCSB consumption reported greater increases in sugar intake (18.4 ± 4.8 g) compared with those who increased LCSB consumption (5.7 ± 4.9 g) or remained high LCSB consumers (5.9 ± 7.4 g), but this trend was not statistically significant after a correction for multiple testing.ConclusionsLCSB consumption was associated with higher energy intake in youth with type 2 diabetes, with the highest energy intakes reported in high LCSB consumers. Those who reduced LCSB consumption tended to report greater increases in sugar intake during follow-up, but further studies are needed to better understand this trend. 相似文献

OBJECTIVE: This study examined baseline dietary intake, body weight, and physiologic status in patients enrolled in a dietary intervention for type 2 diabetes mellitus (T2DM). METHODS: Dietary, physiologic, and demographic information were collected at baseline from 40 adult patients with poorly controlled T2DM (glycosylated hemoglobin >7%) who participated in a clinical trial at an academic medical center in Worcester, Massachusetts, USA. RESULTS: The average age at enrollment was 53.5 y (SD 8.4), average body mass index was 35.48 kg/m(2) (SD 7.0), and glycosylated hemoglobin was 8.3% (SD 1.2). Participants were predominantly white, married, and employed full time. Forty-eight percent were men. Seventy-eight percent had hyperlipidemia, and 68% had hypertension. Reported baseline daily average energy intake was 1778 kcal (SD 814), daily carbohydrate was 159 g (SD 71.5), and dietary fiber was 11.4 g (SD 5.2). The dietary composition was 35% carbohydrate, 45% fat (15% saturated fat), and 20% protein. The American Diabetes Association (ADA) guidelines recommends 45-65% of energy from carbohydrate, 20-35% from fat (<7% saturated), and 20% from protein. CONCLUSION: These patients reported a low-carbohydrate, low-fiber, high-fat (especially saturated) diet, although they stated they are not following any of the popular low-carbohydrate diets. Patients with T2DM may find the current trend toward reducing weight through low-carbohydrate diets attractive for control of blood glucose, despite ADA recommendations. This dietary pattern may represent a popular trend that extends beyond our particular study and, if so, has serious cardiovascular implications in this vulnerable population of T2DM patients. 相似文献

BackgroundModifying foodservice practices in military dining facilities could influence ad libitum nutritional intake patterns of soldiers.ObjectiveWe aimed to determine how changes in foodservice operations consistent with 2005 Dietary Guidelines for Americans affected soldiers' ad libitum nutritional intake in military dining facilities (DFACs).DesignTen DFACs participated, and the intervention was implemented in five DFACs in an independently sampled, partial crossover design. Nutrient intake of diners was assessed during a test meal using digital photography, and customer satisfaction with foodservice was assessed via surveys at baseline (n=602), and again at 6 months (n=519) and 12 months (n=458) after the intervention was implemented.ParticipantsVolunteers were US Army active duty soldiers recruited from among diners at 10 DFACs on Fort Bragg, NC.Main outcome measuresPrimary outcomes were intakes of energy and total fat, and percent energy from fat and saturated fat. Differences between diners' intakes in control and intervention DFACs were assessed using independent samples t tests.ResultsAt 6 months after implementing the intervention, diners at intervention DFACs had significantly lower lunchtime intakes of energy (945±338 kcal vs 1,061±380 kcal), total fat (38±19 g vs 47±25 g), percent energy from fat (35%±10% vs 39%±11%) and saturated fat (4.7%±1.7% vs 5.6%±2.3%), discretionary fat (30±18 g vs 39±24 g), and refined grains (2.3±1.7 oz equivalents vs 2.8±2.4 oz equivalents) compared with diners at control DFACs. Further, diners at intervention DFACs rated customer satisfaction higher than diners at control DFACs.ConclusionsThese findings suggest that modest changes in military DFAC serving practices to promote healthy eating and food selection can facilitate positive changes in soldiers' nutritional intake. 相似文献

Physical inactivity and being overweight or obese are lifestyle factors that put breast cancer survivors at a higher risk for a cancer recurrence and/or development of other chronic diseases. Despite this, there is limited research that has identified effective lifestyle interventions aimed specifically at weight loss in breast cancer survivors. This pilot study is a single-arm experimental pre-post test design, conducted from November 2009 to July 2010, that tested the efficacy of a 24-week group-based lifestyle intervention modeled on the Diabetes Prevention Program in early stage breast cancer survivors (N=14). The intervention included 16 diet sessions led by a registered dietitian and 150 min/wk of moderate-to-vigorous exercise. Study outcome measures were completed at baseline, 24, and 36 weeks (nonintervention follow-up). The primary outcome was change in body weight, and secondary outcomes were change in body composition, aerobic fitness, dietary intake, and blood biomarkers. Overall, participants were postmenopausal women aged 54.6±8.3 years with obesity (body mass index 30.1±3.6), and had completed adjuvant cancer treatment 2 years prior. Results showed an average weight loss of 3.8±5.0 kg and a decrease in body mass index, percent body fat, and waist and hip circumferences at 24 weeks and an additional mean weight loss of 0.8±1.2 kg at 36 weeks. In exploratory analysis, participants who lost >7% body weight were older and attended a greater percentage of diet and supervised exercise sessions. There were no significant changes in any of the blood biomarkers at 24 and 36 weeks; however, the results provide a measure of expected effect size for future research studies. This pilot study demonstrated the efficacy of a lifestyle intervention based on the Diabetes Prevention Program in early stage breast cancer survivors and represents an innovative clinical intervention for dietetics practitioners to address the unmet need for programs. 相似文献

BackgroundCross-sectional studies suggest that parents eat more saturated fat than nonparents. Few studies exist on other dietary factors or using longitudinal data.ObjectiveTo compare change in daily dietary intake of selected foods and nutrients across 7 years between adults who have children enter the home and those who do not.DesignAnalysis of data from the Coronary Artery Risk Development in Young Adults cohort study. Dietary intake was assessed by the diet history questionnaire used in that study. The main dependent variables were change from baseline (1985-1986) to Year 7 (1992-1993) for intake of percent saturated fat, energy, daily servings of fruits and vegetables and sugar-sweetened beverages, and frequency of fast-food intake. The primary independent variable was whether or not participants had children in their home by Year 7.ParticipantsTwo thousand five hundred sixty-three black and white adults who did not have children at baseline from four urban centers.Statistical analyses performedLinear regression adjusting for baseline demographics, energy intake, physical activity, and smoking status.ResultsParents were more likely to be women, full-time workers, married, and older. Diet did not differ at baseline. Seven-year change in diet for parents and nonparents did not differ for fruit and vegetable, sugar-sweetened beverages, or fast food. Percent saturated fat decreased among both groups but parents showed a smaller decrease in percent saturated fat (1.59 vs 2.10; P<0.001). Compared with nonparents, parents increased energy intake by 79 kcal/day (P=0.058), but this difference did not reach statistical significance.ConclusionsParenthood does not have unfavorable effects on parents' diets, but neither does it lead to significant improvements. In fact, parents lag behind their childless counterparts in decreasing intake of saturated fat and overall diets remain poor. Nutrition education programs and food and nutrition practitioners should develop strategies to support and motivate healthy eating habits in parents. 相似文献

Plasminogen activator inhibitor 1 (PAI-1) is elevated in obese individuals with type 2 diabetes and may contribute, independently of traditional factors, to increased cardiovascular disease risk. Fiber intake may decrease PAI-1 levels. We examined the associations of fiber intake and its changes with PAI-1 before and during an intensive lifestyle intervention (ILI) for weight loss in 1,701 Look AHEAD (Action for Health in Diabetes) participants with dietary, fitness, and PAI-1 data at baseline and 1 year. Look AHEAD was a randomized cardiovascular disease trial in 5,145 overweight/obese patients with type 2 diabetes, comparing ILI (goal of ≥7% reduction in baseline weight) with a control arm of diabetes support and education. ILI participants were encouraged to consume vegetables, fruits, and grain products low in sugar and fat. At baseline, median fiber intake was 17.9 g/day. Each 8.3 g/day higher fiber intake was associated with a 9.2% lower PAI-1 level (P=0.008); this association persisted after weight and fitness adjustments (P=0.03). Higher baseline intake of fruit (P=0.019) and high-fiber grain and cereal (P=0.029) were related to lower PAI-1 levels. Although successful in improving weight and physical fitness at 1 year, the ILI in Look AHEAD resulted in small increases in fiber intake (4.1 g/day, compared with –2.35 g/day with diabetes support and education) that were not related to PAI-1 change (P=0.34). Only 31.3% of ILI participants (39.8% of women, 19.1% of men) met daily fiber intake recommendations. Increasing fiber intake in overweight/obese individuals with diabetes interested in weight loss is challenging. Future studies evaluating changes in fiber consumption during weight loss interventions are warranted. 相似文献

BackgroundUltra-processed foods are highly palatable and can be consumed anywhere at any time, but typically have a poor nutritional profile. Therefore, their contribution to total energy intake has been proposed as an indicator for studying overall dietary quality.ObjectiveThe aim of this study was to investigate the associations between the energy contribution from ultra-processed foods and the intake of nutrients related to chronic non-communicable diseases in Mexico.DesignThis study used a secondary analysis of cross-sectional data from the 2012 Mexican National Health and Nutrition Survey.Participants/settingThis study included participants aged 1 year and older (n=10,087) who had completed a 1-day 24-hour recall.Main outcome measuresIntake from added sugar (% kcal), total fat (% kcal), saturated fat (% kcal), protein (% kcal), dietary fiber (g/1,000 kcal), and dietary energy density (kcal/g) were measured.Statistical analysisMultiple linear regression models adjusted for sociodemographic variables were fitted to assess the association between quintiles of energy contribution from ultra-processed foods and nutrient intake.ResultsMean reported energy contribution from ultra-processed foods to the Mexican population’s diet ranged from 4.5% kcal in quintile 1 (Q1) to 64.2% kcal in quintile 5 (Q5). An increased energy contribution from ultra-processed foods was positively associated with intake from added sugar (Q1: 7.4% kcal; Q5: 17.5% kcal), total fat (Q1: 30.6% kcal; Q5: 33.5% kcal) and saturated fat (Q1: 9.3% kcal; Q5: 13.2% kcal), as well as dietary energy density (Q1: 1.4 kcal/g; Q5: 2.0 kcal/g) (P≤0.001); and inversely associated with intake from protein (Q1: 15.1% kcal; Q5: 11.9% kcal) and dietary fiber (Q1: 16.0 g/1,000 kcal; Q5: 8.4 g/1,000 kcal) (P≤0.001).ConclusionsIn the Mexican population, an increased energy contribution from ultra-processed foods was associated with a lower dietary quality with regard to intake of nutrients related to chronic non-communicable diseases. Future research is needed to identify barriers to eating a variety of unprocessed and minimally processed foods for the Mexican population, as well as effective public health strategies and policies to overcome these barriers. 相似文献

Purpose: To evaluate the feasibility of translating the Diabetes Prevention Program (DPP) lifestyle intervention into practice in a rural community. Methods: In 2008, the Montana Diabetes Control Program worked collaboratively with Holy Rosary Healthcare to implement an adapted group-based DPP lifestyle intervention. Adults at high risk for diabetes and cardiovascular disease were recruited and enrolled (N = 101). Participants set targets to reduce fat intake and increase physical activity (≥150 mins/week) in order to achieve a 7% weight loss goal. Findings: Eighty-three percent (n = 84) of participants completed the 16-session core program and 65 (64%) participated in 1 or more after-core sessions. Of those completing the core program, the mean participation was 14.4 ± 1.6 and 3.9 ± 1.6 sessions during the core and after core, respectively. Sixty-five percent of participants met the 150-min-per-week physical activity goal during the core program. Sixty-two percent achieved the 7% weight loss goal and 78% achieved at least a 5% weight loss during the core program. The average weight loss per participant was 7.5 kg (range, 0 to 19.7 kg), which was 7.5% of initial body weight. At the last recorded weight in the after core, 52% of participants had met the 7% weight loss goal and 66% had achieved at least a 5% weight loss. Conclusion: Our findings suggest that it is feasible to implement a group-based DPP in a rural community and achieve weight loss and physical goals that are comparable to those achieved in the DPP. 相似文献

OBJECTIVE: Measure relationships of locus of control and social support to diet changes in an intervention trial. DESIGN: Participants in the Polyp Prevention Trial (PPT) completed Multidimensional Health Locus of Control (MHLC) and Norbeck Social Support Questionnaires (NSSQ) and modified Block food frequency questionnaires. Data were collected at baseline and 1 year later. SUBJECTS/SETTING: A convenience sample of PPT intervention (N = 68) and control (n = 43) participants at 1 clinical center participated in this ancillary study. MAIN OUTCOME MEASURES: Mean daily dietary intakes after 1 year were compared with baseline values. Intervention participants' scores for MHLC internal locus of control and NSSQ total functional network were correlated with diet changes. STATISTICAL ANALYSES PERFORMED: Group percentages were compared using the Fisher exact test; means were compared by t test. RESULTS: Groups were comparable in demographics, baseline diet, and scores for internal locus of control and total functional network. Intervention group participants made greater diet changes than control participants in intake of fat (-27 g vs -8 g), fat as a percentage of kilocalories (-8% vs -2%), fiber as grams per 1,000 kcal (7 g vs 0.3 g), and daily fruit/vegetable servings (2.0 vs 0.2). Pearson correlations of diet changes with internal locus of control scores (all P > .05) were fat grams, r = 0.031; fat as percentage of kilocalories, r = 0.023; fiber grams per 1,000 kcal; r = 0.230; and fruit/vegetable servings, r = 0.186. Correlations with total functional network scores were: fat grams, r = 0.022 (P > .05); fat as percentage of kilocalories, r = -0.108 (P > .05); fiber grams per 1,000 kcal, r = 0.276, P < .05; and daily fruit/vegetable servings, r = 0.326, P < .05. APPLICATIONS/CONCLUSIONS: Intensive and skillful dietary intervention can succeed whether or not clients bring strong internal locus of control or social support to the diet change program. 相似文献

Although dietary counseling is generally recommended in children with food allergy (FA), its effect on the nutritional status of these patients has not yet been evaluated. Our nonrandomized multicenter prospective intervention study was undertaken to investigate the effects of dietary counseling on children with FA. Anthropometric data, dietary intakes, and laboratory biomarkers of nutritional status were evaluated in children with FA (aged 6 to 36 months) before and after dietary counseling, by multidisciplinary teams composed of pediatricians, dietitians, and nurses. Ninety-one children with FA (49 boys and 42 girls; mean age 18.9 months, 95% CI 16.5 to 21.3) were evaluated; 66 children without FA (41 boys and 25 girls; mean age 20.3 months, 95% CI 17.7 to 22.8) served as controls providing baseline values only. At enrollment, energy and protein intakes were lower in children with FA (91 kcal/kg/day, interquartile range [IQR]=15.1, minimum=55.2, maximum=130.6; and 2.2 g/kg/day, IQR=0.5, minimum=1.5, maximum=2.7, respectively) than in children without FA (96 kcal/kg/day, IQR=6.1, minimum=83.6, maximum=118.0; and 4.6 g/kg/day, IQR=1.2, minimum=2.0, maximum=6.1, respectively; P<0.001). A weight to length ratio <2 standard deviations was more frequent in children with FA than in children without FA (21% vs 3%; P<0.001). At 6 months following dietary counseling, the total energy intake of children with FA was similar to the baseline values of control children. Dietary counseling also resulted in a significant improvement of their anthropometric and laboratory biomarkers of nutritional status. The results of our study support the crucial role of dietary counseling in the clinical management of children with FA. 相似文献

Objective To determine whether the daily intake of 2,092 kJ (500 kcal) from peanuts will improve the lipid profiles and diet quality of healthy Ghanaians.Design A 30-week, randomized, cross-over trial study was conducted with healthy adults.Method There were three treatment arms: Treatment 1 (T1), subjects were provided 2,092 kJ/day (500 kcal/day) peanuts to incorporate into their daily diet for 8 weeks at any time and in any form they chose; Treatment 2 (T2), subjects were provided 2,092 kJ/day (500 kcal/day) peanuts and were instructed to consume them in addition to their customary daily diet for 3 weeks; Treatment 3 (T3), substitution of 2,092 kJ/day fat, with energy from peanuts. Total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol and triglyceride were measured at baseline, week 4 and week 8 (T1 and T3) or at baseline and week 3 (T2). Three-day dietary intake records were kept during each treatment.Results There was significant decrease in total cholesterol (7.2%) and triacylglycerol (20.0%) after T1. However, individually, high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol levels did not change significantly. Total fat intake increased by 9%, due to elevations of monounsaturated fatty acid of 60% and polyunsaturated fatty acid of 50%. Similar non-significant trends were observed during T2 and T3.Conclusion The results suggest that regular consumption of peanuts lowers the total cholesterol and triacylglycerol concentrations among healthy Ghanaians. Regular consumption of peanuts should therefore be encouraged. 相似文献

Because day-to-day food intake varies, we tested the hypothesis that ad libitum food intake and energy expenditure show corrective responses over periods of 1 to 10 days in healthy young women. Food intake and accelerometry measurements were collected daily for 17 days in 15 young women. Total daily energy expenditure (TDEE) using doubly labeled water was also measured. The daily deviations in macronutrient and energy intake and energy expenditure from the average values were compared with the deviations observed over succeeding intervals to estimate the corrective responses. The intraindividual coefficients of variation for energy intake averaged ±25%, ranging from 16% to 34%. TDEE had a coefficient of variation of 8.3%, and accelerometry had a coefficient of variation of 8.4% (range=4.6% to 16.4%). Energy expenditure by accelerometry (2,087±191 kcal/day) was not significantly different from TDEE (2,128±177 kcal/day), but reported daily energy intake was 20.4% lower (1,693±276 kcal/day). There were significant corrective responses in energy from fat and total energy intake. This occurred from Days 3 to 6, with a peak at Day 5 that disappeared when data were randomized within each subject. Human beings show corrective responses to deviations from average energy and macronutrient intakes with a lag time of 3 to 6 days, but not 1 to 2 days. These corrective responses are likely to play a role in bringing about weight stability. 相似文献

OBJECTIVE: To compare age-related changes in macronutrient and cholesterol intake between black and white girls, compare intakes with National Cholesterol Education Program (NCEP) recommendations, and examine sociodemographic associations with macronutrient intake. DESIGN: Cohort study with 3-day food records collected over 10 years. SUBJECTS: 2,379 girls, 1,166 white and 1,213 black, age 9 to 10 years at baseline, recruited from three geographic locations. Statistical Analysis Longitudinal generalized estimating equation (GEE) regression models examined the relationships of age, ethnicity, and sociodemographic factors with macronutrient and cholesterol intake and with percentage of girls meeting NCEP recommendations. RESULTS: Total and saturated fat intakes decreased with age, more in white girls than black girls, from 35.1% and 13.6% kcal at age 9 to 29.3% and 10.4% at age 19 for white girls and from 36.5% and 13.4% kcal at age 9 to 35.1% and 11.7% kcal at age 19 for black girls. Dietary cholesterol decreased with age, but decreased more in white girls than black girls (range 95 to 119 mg/1,000 kcal for white girls and 119 to 132 mg/1,000 kcal for black girls). Depending on age, 7% to 51% of white girls and 8% to 26% of black girls met NCEP recommendations for total fat (相似文献

BackgroundBreakfast consumption is often associated with improving cardiometabolic parameters and diet quality. However, literature evaluating breakfast consumption with these outcomes between the school and home environments is limited.ObjectiveThis study examined relationships between breakfast consumption locations (school vs home) and cardiometabolic parameters, breakfast dietary intake, and daily dietary intake.DesignThis cross-sectional study used baseline data from TX Sprouts, a 1-year school-based gardening, nutrition, and cooking cluster-randomized trial, implemented in 16 elementary schools in Austin, TX, during 2016 to 2019.Participants/settingAnalyses included 383 low-income, multiracial/ethnic elementary school-aged children (mean age = 9.2 years; 60.6% Hispanic; 70.5% free/reduced lunch; 58.5% home breakfast consumers).Main outcome measuresCardiometabolic parameters were obtained via fasting blood draws, and dietary intake was assessed using one 24-hour dietary recall conducted on a random, unannounced weekday. Cardiometabolic and dietary parameters (ie, energy intake, macronutrients, and food group servings) for breakfast and for the day were evaluated.Statistical analyses performedMultivariate analysis of covariance was performed to examine cardiometabolic parameters and dietary intake between school and home breakfasts.ResultsSchool breakfast consumers (SBC) had lower fasting triglyceride levels than home breakfast consumers (HBC) (89.0 mg/dL vs 95.7 mg/dL; P = 0.03) (to convert to mmol/L, multiply by 0.0113). SBC had lower total fat for the day (P = 0.02) and lower total and saturated fat, sodium, and refined grains at breakfast (P ≤ 0.01) than HBC. However, SBC had lower protein at breakfast (P = 0.01) and higher carbohydrates, total sugar, and added sugar for the day and at breakfast (P ≤ 0.03) than HBC.ConclusionsSBC compared with HBC had lower fat intake, which may have contributed to the lower triglyceride level observed in SBC, but also had lower protein intake at breakfast and higher added sugar intake for the day and at breakfast. These results suggest dietary intake differed between HBC and SBC; that is, the home and school environments, but more research is needed to evaluate if such differences are due to School Breakfast Program guidelines. 相似文献

This pilot study evaluated a high-energy, high-protein, peptide-based, (medium-chain triglycerides) MCT-containing enteral tube feed (Nutrison Peptisorb Plus HEHP®, Nutricia Ltd., Trowbridge, BA14 0XQ, UK.) containing 1.5 kcal/mL and 7.5 g protein/100 mL. Fifteen community-based, enterally tube-fed adults (42 (SD 16.3) years) received the intervention feed daily for 28 days, with gastrointestinal tolerance, compliance and nutrient intake assessed at baseline and after the intervention period. Incidence and intensity of constipation (p = 0.496), nausea (p = 1.000), abdominal pain (p = 0.366) and bloating (p = 0.250) remained statistically unchanged, yet the incidence and intensity of diarrhoea improved significantly after receiving the intervention feed (Z = −2.271, p = 0.023). Compliance with the intervention feed was significantly greater compared to the patient’s baseline regimens (99% vs. 87%, p = 0.038). Compared to baseline, use of the intervention feed enabled patients to significantly increase total energy (1676 kcal/day (SD 449) to 1884 kcal/day (SD 537), p = 0.039) and protein intake (73 g/day (SD 17) to 89 g/day (SD 23), p = 0.001), allowing patients to better achieve energy (from 88% to 99%, p = 0.038) and protein (from 101% to 121%, p < 0.001) requirements. This pilot study demonstrates that a high-energy, high-protein, peptide-based, MCT-containing enteral tube feed maintains gastrointestinal tolerance and improves compliance, energy and protein intake in complex, enterally tube-fed, community-based adult patients, though more work is recommended to confirm this. 相似文献

OBJECTIVES: To evaluate the feasibility and long-term compliance with a low-fat diet supplemented with soy protein in men at increased risk for recurrence after radical prostatectomy. DESIGN: Randomized, control study.Setting:Academic center in USA. SUBJECT: Forty men who had undergone radical prostatectomy and were at increased risk for recurrence. INTERVENTION: Low-fat (15% fat), high-fiber (18 g/1000 kcal) diet supplemented with 40 g soy protein isolate (n=26) was compared to USDA recommended diet (n=14). RESULTS: Over 4 years, subjects in the intervention group but not in the control group made and sustained significant changes in their diet as measured by the dietary assessment instruments and urinary isoflavone excretion. In the intervention group, dietary fat intake was reduced from 33.46+/-1.27% energy/day to 21.04+/-1.74% (P<0.05), fiber intake increased from 14.6+/-1.06 to 21.05+/-2.29 g/day. The insulin growth factor-1 (IGF-1) level was decreased from 260.4+/-8.6 ng/ml at baseline to 220.5+/-7.9 ng/ml at 6 months (P<0.05) in the intervention group with no significant change in the control group. An ex vivo assay demonstrated inhibition of LNCaP cell growth (-20.0+/-7.7%, P<0.05) by sera from patients in the intervention group after 6 months of dietary change compared to baseline. CONCLUSION: These data suggest that long-term low-fat dietary interventions as part of prospective randomized trials in prostate cancer survivors are feasible, and lead to reductions in circulating hormones or other growth factors stimulating prostate cancer growth ex vivo. 相似文献

This cross-sectional study investigates the association between energy intake and macronutrient composition of the diet with overweight and obesity among Malaysian women. One hundred and fifteen adult Malay women aged 20 to 59 years (mean age 37.2±7.6 years) were interviewed. Dietary intake was assessed using the food history method. Body weight status was assessed using weight, height, waist circumference and fat percentage measurements. When energy intake was assessed for accuracy, only 41% of the subjects (n=47) were normal energy reporters. Among the normal energy reporters, 55% were of normal weight whereas 32% and 13% were overweight and obese. Mean energy intake for normal weight, overweight and obese subjects was 1685±199 kcal/day, 1810±166 kcal/day and 2119±222 kcal/day, respectively. Energy intake increased with body mass index (BMI) category. Among the overweight and obese, energy intake was respectively higher by 125 kcal/day and 434 kcal/day as compared to their normal weight counterparts (p< 0.001). There was also a significant, moderate and positive correlation between energy intake and BMI (r=0.635), waist circumference (r=0.545), and body fat percentage (r=0.534). When macronutrient composition of diet was analysed (% energy and g/1000 kcal), there was no significant difference in carbohydrate, protein or fat intake between the obese, overweight and normal weight subjects. There was also no significant correlation between macronutrient composition of the diet and body weight status. Based on these findings, we conclude that the subjects' body weight status is likely to be influenced by energy intake rather than the macronutrient composition of the diet. 相似文献

ObjectiveWeight loss is common in patients with malignant tumors and it can adversely affect quality of life and survival. The aim of the present study was to investigate the effects of a nutritional intervention in cancer patients in an outpatient setting.MethodsCancer outpatients (N = 58) who were classified as undernourished or at high risk for undernutrition by the Nutritional Risk Screening 2002 tool were randomized into two groups. One group (n = 30) received standardized individual nutritional therapy, including counseling by a dietitian, food fortification, and oral nutritional supplements if required. The second group (n = 28) received standard care. The nutritional intervention lasted 3 mo. Dietary intake (3-d dietary record), nutritional status (body weight), physical functioning (performance status, hand-grip strength) and quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire version 3.0) were assessed at baseline and after 6 wk and 3 mo. An additional follow-up assessment was carried out 3 mo post-intervention.ResultsNutritional intervention led to a significantly higher average energy and protein intake in the nutritional therapy group (+379 kcal; 95% confidence interval [CI], 117–642; P = 0.007, respectively; +10.4 g; 95% CI, 2.3–18.5; P = 0.016). However, the increased dietary intake was not associated with improvements in nutritional status, physical functioning, or quality of life.ConclusionsIndividual nutritional counseling significantly and positively influenced energy and protein intake, but did not improve nutritional or physical outcome or quality of life. These results indicate that nutritional therapy alone is of limited efficacy in cancer patients whose nutritional status has already deteriorated. 相似文献

BackgroundCurrent dietary guidelines recommend avoiding foods and beverages with added sugars and higher sodium before age 2 years.ObjectiveThe aim was to describe daily snack food intake (frequency and total energy) and the associations with overconsumed nutrients (added sugars, sodium, and saturated fats) and child weight-for-length z scores.DesignA cross-sectional, secondary analysis of baseline data from an ongoing longitudinal intervention was conducted.Participants and settingA sample of 141 caregivers with infants (aged 9 to 11 months) and toddlers (aged 12 to 15 months) was recruited in Buffalo, NY, between 2017 and 2019.Main outcome measuresThree 24-hour dietary recalls were used to categorize 'sweet and salty snack foods' or 'commercial baby snack foods' based on the US Department of Agriculture What We Eat in America food group classifications and estimate nutrient intakes. Child recumbent length and weight were measured by trained researchers.Statistical analysisDaily frequency (times/day), energy (kcal/day), and overconsumed nutrients from snack food intake were calculated. Multivariable regression models examined associations between the frequency of and energy from snack food intake with overconsumed nutrients and child weight-for-length z scores.ResultsInfants consumed snack foods on average 1.2 times/day contributing 5.6% of total daily energy, 19.6% of added sugars, and 6.8% of sodium. Toddlers consumed snack foods on average 1.4 times/day contributing 8.9% of total daily energy, 40.0% of added sugars, and 7.2% of sodium. In adjusted models including all children, greater frequency of sweet and salty snack food intake, but not commercial baby snack foods, was associated with higher weight-for-length z scores.ConclusionsSnack foods are frequently consumed by infants and toddlers and contribute to the intake of overconsumed nutrients such as added sugars and sodium. Given the current guidelines to avoid added sugars and higher sodium before age 2 years, additional recommendations related to nutrient-dense snack intake may be beneficial. 相似文献
