Obesity and overweight-obesity have contributed to increases in early mortality and noncommunicable disease incidence. The consumption of sugar-sweetened beverages (SSBs) is linked to obesity, weight gain, and metabolic syndrome. To further explore this relationship in a large urban environment, we assessed disparities in calorie intake between SSB and non-SSB consumers and determine the association between varying SSB consumption, obesity, and overweight-obesity using data from a 2013 representative dietary survey conducted in New York City. Results show that adult SSB drinkers consume 193 kcal/day from SSBs, approximately 10 % of daily caloric needs. Compared to non-SSB drinkers, those who consume SSBs have a 572 kcal greater daily intake. Total calorie differences are due to greater SSB calorie and food calorie consumption. Among SSB consumers, each 10-oz increase in SSB consumption is associated with a greater likelihood of obesity (OR 1.62, 95 % CI 1.05, 2.05) and overweight-obesity (OR 2.23, 95 % CI 1.31, 3.80). Additionally, each 10-kcal SSB increase is related to obesity (OR 1.04, 95 % CI 1.01, 1.08) and overweight-obesity (OR 1.07, 95 % CI 1.02, 1.11). 相似文献

Using a representative dataset from the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2011, we analyzed anthropometric and dual-energy X-ray absorptiometry (DXA)-determined body composition findings for 493 cancer survivors (mean age a61.1 ± 12.6 years; 35.7% male). A much higher proportion of men (30.1%) than women (0.6%) met the criteria of sarcopenia. Subjects with a history of lung cancer, genitourinary cancer, or gastric cancer were prone to develop sarcopenia (31.6%, 26.3%, and 21.4%, respectively). Furthermore, sarcopenia was more prevalent among elderly (≥65 years; P < 0.001), those with a lower BMI level (<23 kg/m 2; P < 0.001), heavy drinker ( P = 0.012), or smoker ( P < 0.001), and those with inadequate intakes of protein ( P = 0.017) and vitamin A ( P = 0.024). Multivariable logistic analyses revealed sarcopenia was significantly associated with male gender (odds ratio [OR], 68.14; 95% CI, 15.52–299.13), a BMI of <23 kg/m 2 (OR 35.93, 95% CI, 8.24–156.67), and inadequate protein intake (OR 3.07, 95% CI, 1.30–7.22); these factors are significant predictors of sarcopenia in Korean cancer survivors. 相似文献

Soy food and its constituents may protect against breast cancer, but the association between soy intake and decreased breast cancer risk is inconsistent. We evaluated the relationship between breast cancer risk and the dietary intake of soy protein as measured by total soy food and tofu intake. Histologically confirmed cases ( n = 362) were matched to controls by age (within 2 yr) and menopausal status. High soy protein intake was associated with reduced breast cancer risk in analyses adjusted for potential confounders including dietary factors among premenopausal women (odds ratio [OR] = 0.39 in the highest quintile, 95% confidence interval [CI] = 0.22–0.93, P for trend = 0.03) and postmenopausal women (OR = 0.22, 95% CI = 0.06–0.88, P for trend = 0.16). We also found an inverse association between total tofu intake and breast cancer risk among premenopausal women (for total tofu intake, OR = 0.23 in the highest quintile, 95% CI = 0.11–0.48, P for trend < 0.01; for at least 1 serving of tofu as the main ingredient per day, OR = 0.26, 95% CI = 0.13–0.55, P for trend < 0.01). We concluded that increased regular soy food intake at a level equivalent to traditional Korean consumption levels may be associated with a reduced risk of breast cancer, and this effect is more pronounced in premenopausal women. 相似文献

PurposeThe associations between specific carotenoid intake and colorectal cancer risk remain inconsistent. The aim of this study was to examine the association between specific dietary carotenoid intake with colorectal cancer risk in Chinese adults.MethodFrom July 2010 to October 2013, 845 eligible colorectal cancer cases and 845 frequency-matched controls (age and sex) completed in-person interviews. A validated food frequency questionnaire was used to estimate dietary intake. Multivariate logistical regression models were used to calculate the odds ratio (OR) and 95 % confidence intervals (95 % CIs) of colorectal cancer risk after adjusting for various confounders.ResultsA strong inverse association was found between β-cryptoxanthin intake and colorectal cancer risk. Compared with the lowest quartile, the highest quartile intake showed a risk reduction of 77 % (OR 0.23, 95 % CI 0.17–0.33, P trend < 0.01) after adjustment for various confounding variables. The inverse associations were also observed for α-carotene (OR 0.50, 95 % CI 0.37–0.68, P trend < 0.01), β-carotene (OR 0.67, 95 % CI 0.49–0.91, P trend < 0.01), and lycopene (OR 0.51, 95 % CI 0.37–0.70, P trend < 0.01). There was no statistically significant association between lutein/zeaxanthin intake and colorectal cancer risk. These findings were consistent across cancer site, sources of controls, and smoking status. The inverse associations between dietary α-carotene, β-cryptoxanthin, and lycopene intake and colorectal cancer risk were found in both males and females, while inverse associations between β-carotene intake and colorectal cancer risk were only observed in males.ConclusionsConsumption of α-carotene, β-carotene, β-cryptoxanthin, and lycopene was inversely associated with colorectal cancer risk. No significant association was found between lutein/zeaxanthin intake and colorectal cancer risk. 相似文献

ObjectivesIt has been suggested that birth weight may determine metabolic abnormalities later in life. The aim of the current study was to assess the association between birth weight and future risk of gestational diabetes mellitus (GDM) and pregravid obesity in a homogenous sample of Caucasian Polish women. MethodsIn this retrospective study, we collected the medical reports of 787 women with GDM and 801 healthy pregnant women. We analyzed the following data: birth weight, age, pregravid weight, prior GDM, prior macrosomia, parity, and family history of diabetes. ResultsBirth weight was inversely associated with the risk of GDM; for each decrease in birth weight of 500 g, the risk increased by 11% (odds ratio [OR], 1.11; 95% confidence interval [CI], 1.02–1.21). Birth weight was a strong predictor of GDM independent of other risk factors (OR, 1.19; 95% CI, 1.09–1.31), and it was positively correlated with pregravid weight (R = 0.21; P < 0.00001). An increase in birth weight of 500 g substantially increased the risk of overweight and obesity (OR, 1.17; 95% CI, 1.01–1.34 and OR, 1.35; 95% CI 1.11–1.64, respectively). Each of the traditional risk factors for GDM were also strong predictors of pregravid obesity: age ( P < 0.0001), prior GDM ( P < 0.01), prior macrosomia ( P < 0.0001), multiparity ( P < 0.0001), and maternal (but not paternal) history of diabetes ( P < 0.0001). ConclusionsAmong Caucasian Polish women, the risk of GDM is associated with low birth weight, and pregravid obesity is associated with high birth weight. Traditional risk factors for GDM, including maternal (but not paternal) history of diabetes, are also risk factors for pregravid obesity. 相似文献

Dietary red meat and animal fat have been linked to endometrial cancer (EC) risk, but the impact of bioavailable iron in animal-derived foods has been less well studied. Our objective was to investigate the effects of iron and fats on the risk of EC in a large, population-based, case-control study. The Shanghai Endometrial Cancer Study enrolled 1,204 EC cases and 1,212 controls who completed in-person interviews, including a food frequency questionnaire. Animal-derived iron and fat intakes were calculated from dietary intakes and food composition tables. Logistic regression models were used to evaluate independent and joint effects of iron and fat on EC risk. Animal-derived iron intake was positively associated with EC risk [adjusted OR = 1.9; 95% CI = 1.4–2.7, P trend < 0.01, highest vs. lowest quartile], predominantly after menopause (OR = 2.2; 95%CI = 1.4–3.4, P trend < 0.01) and in women with BMI ≥ 25 kg/m 2 (OR = 3.2; 95% CI = 1.4–7.5 in postmenopausal obese women, P trend < 0.01). Animal-derived fat was also associated with postmenopausal EC risk (OR = 1.7; 95% CI = 1.2–2.5, P trend < 0.01). Multiplicative interactions between animal-derived iron and BMI or animal-derived fat intake were not observed. Animal-derived iron intake is associated with increased risk of EC after menopause and among obese women. Avoidance of animal-derived (heme) iron may reduce the risk of EC in these women. 相似文献

ABSTRACTThis study aimed to clarify the association between the frequency of dining out and the risk of obesity, diabetes mellitus, and dyslipidemia among Korean adults. This cross-sectional study surveyed 640 participants aged 20–69 years in Korea. Daily intake of energy, fat, protein, and cholesterol significantly increased as the frequency of dining out increased ( P < .001). Energy derived from carbohydrates significantly decreased with the frequency of dining out, while that derived from fat and protein increased ( P < .001). Among participants who rarely dined out, the fully adjusted odds ratios (ORs) for hyperglycemia were significantly lower at 0.35 (95% CI, 0.16–0.76). Decreased risk of being hyperglycemia among participants who rarely dined out suggests that the frequency of dining out can be related to diabetes risk. 相似文献

Our objective was to examine the association between dietary fat intake, cooking fat usage, and breast cancer risk in a population-based, multiethnic, case-control study conducted in the San Francisco Bay area. Intake of total fat and types of fat were assessed with a food frequency questionnaire among 1,703 breast cancer cases diagnosed between 1995 and 1999 and 2,045 controls. In addition, preferred use of fat for cooking was assessed. Unconditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). High fat intake was associated with increased risk of breast cancer (highest vs. lowest quartile, adjusted OR = 1.35, 95% CI = 1.10–1.65, P trend < 0.01). A positive association was found for oleic acid (OR = 1.55, 95% CI = 1.14–2.10, P trend < 0.01) but not for linoleic acid or saturated fat. Risk was increased for women cooking with hydrogenated fats (OR = 1.58, 95% CI = 1.20–2.10) or vegetable/corn oil (rich in linoleic acid; OR = 1.30, 95% CI = 1.06–1.58) compared to women using olive/canola oil (rich in oleic acid). Our results suggest that a low-fat diet may play a role in breast cancer prevention. We speculate that monounsaturated trans fats may have driven the discrepant associations between types of fat and breast cancer. 相似文献

Several nutrients identified as potentially cancer protective have been inconsistently associated with non-Hodgkin lymphoma (NHL) risk. Dietary history data, including use of vitamin supplements, were collected using a semiquantitative food frequency questionnaire administered during in-person interviews with 4,133 participants (2,052 cases, 2,081 controls) in a San Francisco Bay Area population-based case-control study. Data were used to determine the association of intake levels of vitamins D and A and calcium with risk of NHL and NHL subtypes. Odds ratios (OR) and 95% confidence intervals (CI) were computed as estimates of relative risk using adjusted unconditional logistic regression. Increasing vitamin D intake from food and supplements was positively associated with NHL risk in men (5th quintile: OR = 1.6, 95% CI = 1.0–2.4, P trend = 0.07) and with diffuse large B-cell lymphoma (DLBCL) in women and men (5th quintile: OR = 1.6, 95% CI = 1.0–2.5, P trend = 0.02); that was largely due to the effect in men ( P trend = 0.03). These results do not support a strong role for vitamin D intake with NHL risk, with the exception of a potential association for DLBCL risk in men. Our results should be interpreted conservatively until further investigation in larger pooled studies can be conducted to better assess the role of vitamin D intake in lymphomagenesis. 相似文献

Metabolic syndrome (MetS) is a complex disorder which has become one of the major public health challenges worldwide. This study was conducted to evaluate the association between dietary advanced glycation end products (AGEs) and risk of MetS and its components. This cross-sectional study was conducted in a representative sample of 5848 adults, aged 19–70 years. Daily consumption of carboxymethyl lysine, a major type of AGEs, was determined using a validated semi-quantitative food frequency questionnaire. Across increasing trend of AGEs consumption, the percentage of fat intake increased and that of carbohydrate significantly decreased ( p?< ?0.001). Subjects in the highest (>10 506 kU/d) compared to the lowest (<6673 kU/d) quartile category of AGEs had higher risk of abdominal obesity (OR: 1.19, 95% CI: 1.01–1.39) and hypertriglyceridemia (OR: 1.26, 95% CI: 1.07–1.49). Therefore, recommendation on restriction of AGEs intake could be a practical approach to prevent metabolic abnormalities. 相似文献

Riboflavin is an essential micronutrient for normal cellular activity, and deficiency may result in disease, such as cancer. We performed a case-control study to explore the association of riboflavin levels with risk and prognosis of esophageal squamous cell carcinoma (ESCC). Plasma riboflavin levels, as measured by enzyme-linked immunosorbent assay (ELISA), in ESCC patients were significantly lower than in those of healthy controls (7.04 ± 6.34 ng/ml vs. 9.32 ± 12.40 ng/ml; P < 0.05). Moreover, there was an inverse relationship between riboflavin level and risk of ESCC (odds ratio (OR) = 0.97, 95% confidence interval (CI) = 0.95–0.99, P = 0.02). The 5-year relapse-free and overall survival rates were significantly lower when riboflavin levels were ≤0.8 ng/ml than >0.8 ng/ml (relapse-free survival rate: 29.4% vs. 54.8%; overall survival rate: 28.6% vs. 55.6%). Plasma riboflavin level was an independent protective factor for both relapse-free (hazard ratio (HR) = 0.325, 95% CI = 0.161–0.657, P = 0.002) and overall survival of ESCC patients (HR = 0.382, 95% CI = 0.190–0.768, P = 0.007). In conclusion, plasma riboflavin levels are significantly related to risk and prognosis of ESCC patients, suggesting that moderate supplementation of riboflavin will decrease risk and prevent recurrence of ESCC and also improve prognosis of ESCC patients. 相似文献

Whether obesity accelerates adenoma recurrence is not yet clear; therefore, we analyzed the risk factors for adenoma occurrence at follow-up colonoscopy, with a focus on visceral adiposity. In total, 1516 subjects underwent index colonoscopy, computed tomography, and questionnaire assessment from February to May 2008; 539 subjects underwent follow-up colonoscopy at the National Cancer Center at least 6 mo after the index colonoscopy. The relationships between the presence of adenoma at follow-up colonoscopy and anthropometric obesity measurements, including body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT) volume, and subcutaneous adipose tissue (SAT) volume, were analyzed. 188 (34.9%) had adenomatous polyps at follow-up colonoscopy. Multivariate analysis revealed that VAT volume ≥ 1000 cm 3 and BMI ≥ 30 kg/m 2 were related to the presence of adenoma at follow-up colonoscopy (VAT volume 1000–1500 cm 3: odds ratio [OR] = 2.13(95% confidence interval, CI = 1.06–4.26), P = 0.034; VAT volume ≥ 1000 cm 3: OR = 2.24(95% CI = 1.03–4.88), P = 0.043; BMI ≥ 30 kg/m 2: OR = 4.22(95% CI = 1.12–15.93), P = 0.034). In contrast, BMI 25–29.9 kg/m 2, SAT volume, and WC were not associated with the presence of adenoma at follow-up colonoscopy. In conclusion, excess VAT can contribute to the development and growth of new colorectal adenomas, and is a better predictor of colorectal adenoma occurrence at follow-up colonoscopy than BMI, WC, and SAT volume. 相似文献

Background and Objective: The high prevalence of obesity in the pediatric age groups draws attention to lifestyle factors including diet and physical activity. Data on obesity in adolescents and their snacking behavior are conflicting. This study aimed to assess the association of snacking behavior and obesity among female adolescents in Isfahan, Iran. Subjects and Design: This cross-sectional study was carried out on 265 female Isfahanian students who were chosen by systematic cluster random sampling. Dietary intake was assessed using a validated self-administered semiquantitative food frequency questionnaire that included 53 food items. Snacking behavior was defined by healthy snack score in combination with the frequency of snack intake. Results: Individuals who consumed more healthy snacks and those with snacking frequency of 4 times a day or more had significantly lower weight, body mass index (BMI), and waist circumference (p < 0.001). Decreased consumption of healthy snacks was significantly associated with a greater chance of being overweight, generally obese, and abdominally obese among adolescents (odds ratio [OR] = 1.98; 95% confidence interval [CI], 1.00–3.14, ptrend = 0.04 and OR = 2.10; 95% CI, 1.01–3.13, ptrend = 0.04, respectively). Frequency of snack intake was inversely related to overweight, general obesity, and abdominal obesity (OR = 3.23; 95% CI, 1.73–5.61, ptrend = 0.03 and OR = 1.84; 95% CI, 1.05–3.20, ptrend = 0.04, respectively). Healthy snack score in combination with frequency of snacking showed that those in the lowest tertile of snacking who consumed snacks less than 4 times/day had the highest risk of obesity compared to other categories (OR = 2.09, 95% CI, 1.11–3.20, p < 0.001). Conclusion: More frequent consumption of healthy snacks is associated with decreased prevalence of overweight, general obesity, and abdominal obesity in adolescents. Further studies, in particular of a prospective nature, are required to examine this association in other populations. 相似文献

This study aimed to add to prospective data on the possible inverse association between coffee consumption and endometrial cancer risk, already supported by several case-control studies. Coffee and tea consumption and possible confounding factors were assessed among 42,270 women aged 30–49 years at enrollment in 1991–1992 in the Swedish Women's Lifestyle and Health cohort study, with complete follow-up through 2009. We calculated caffeine intake per day; Cox proportional hazard models were used to estimate multivariable relative risks (mRR) for endometrial cancer with 95% confidence intervals (CIs). One hundred forty-four endometrial cancers were diagnosed during follow-up. Women with and without endometrial cancer had a similar mean daily coffee consumption (549 vs. 547 g), tea consumption (104 vs. 115 g), and caffeine intake (405 vs. 406 mg). Compared to those consuming <2 cups of coffee per day, women consuming >3 cups had a mRR of 1.56 (95% CI: 0.94–2.59; P for trend = 0.17). Compared with the lowest tertile of caffeine intake, the highest tertile had a mRR of 1.32 (95% CI: 0.87–1.99; P for trend = 0.27). Our study provides no convincing evidence of an association between coffee consumption, tea consumption, or caffeine intake and endometrial cancer risk among middle-aged women. 相似文献

The effects of diet on breast cancer are controversial and whether the effects vary with hormone receptor status has not been well investigated. This study evaluated the associations of dietary factors with risk for breast cancer overall and by the hormone receptor status of tumors among Chinese women. The Shanghai Breast Cancer Study, a large, population-based, case-control study, enrolled 3,443 cases and 3,474 controls in 1996–1998 (phase I) and 2002–2005 (phase II); 2676 cases had estrogen receptor (ER) and progesterone receptor (PR) data. Dietary intake was assessed using a validated, quantitative, food frequency questionnaire. Odds ratios (OR) and 95% confidence intervals (95% CI) were derived from multivariate, polychotomous, unconditional logistic regression models. Total vegetable intake was inversely related to breast cancer risk, with an adjusted OR for the highest quintile of 0.80 (95% CI = 0.67–0.95; P trend = 0.02). Reduced risk was also related to high intake of allium vegetables ( P trend = 0.01) and fresh legumes ( P trend = 0.0008). High intake of citrus fruits and rosaceae fruits were inversely associated with breast cancer risk ( P trend = 0.003 and 0.004, respectively), although no consistent association was seen for total fruit intake. Elevated risk was observed for all types of meat and fish intake (all P trend < 0.05), whereas intakes of eggs and milk were associated with a decreased risk of breast cancer (both P trend <0.05). There was little evidence that associations with dietary intakes varied across the 4 tumor subtypes or between ER+/PR+ and ER-/PR- tumors ( P for heterogeneity >0.05). Our results suggest that high intake of total vegetables, certain fruits, milk, and eggs may reduce the risk of breast cancer, whereas high consumption of animal-source foods may increase risk. The dietary associations did not appear to vary by ER/PR status. 相似文献

Because research focusing on dairy food consumption and the risk for obesity is inconsistent and only a few studies have even examined specific dairy products, in regard to type of food and fat content, in relation to obesity risk, this cross-sectional study investigated whether dairy food consumption is associated with the prevalence of global and abdominal obesity. Data were analyzed from 1352 participants in the Observation of Cardiovascular Risk Factors in Luxembourg survey. We hypothesized that higher total dairy food consumption would be independently associated with reduced prevalence of obesity. A validated food frequency questionnaire was used to measure intakes of dairy foods. Odds for global obesity (body mass index ≥30 kg/m 2) and abdominal obesity (waist circumference >102 cm for men and >88 cm for women) were determined based on total dairy food intake as well as intakes of individual low- and whole-fat dairy products (milk, yogurt, and cheese). Total dairy food intake was inversely associated with the likelihood of global obesity (odds ratio [OR], 0.51; 95% confidence interval [CI], 0.30-0.89; P < .05) and abdominal obesity (OR, 0.51; 95% CI, 0.32-0.83; P < .01). Participants in the highest tertile of whole-fat dairy intakes (milk, cheese, yogurt) had significantly lower odds for being obese (global obesity: OR, 0.45; 95% CI, 0.29-0.72; P < .01; abdominal obesity: OR, 0.35; 95% CI, 0.23-0.54; P < .001), compared with those in the lowest intake tertile, after full adjustment for demographic, lifestyle, dietary, and cardiovascular risk factor variables. Increasing consumption of dairy foods may have the potential to lower the prevalence of global and abdominal obesity. 相似文献

BackgroundTeen dating violence is discussed as a potential risk factor for harmful behaviour. For prevention strategies it is interesting to see the extent to which evidence can be found in epidemiological studies.MethodsWe searched the databases CINAHL, EMBASE, PsycINFO, Cochrane Library, Web of Science as well as in the free web for longitudinal studies which examined substance consumption as a result of teen dating violence.ResultsSeven studies fulfilled the inclusion criteria. Each one study described teen dating violence to increase marijuana consumption among girls (odds ratio [OR] 2.1, 95% confidence interval [95% CI] 1.22–3.70) and boys (OR 1.34, 95% CI 1.03–1.74), two studies with mixed sex population in boys (class 8: b = 0.55, p < 0.01; class 12: b = 1.14, p < 0.001) and in both sexes (ERR = 1.21, 95% CI 0.96–1.52; ERR = 1.30, 95% CI 0.81–2.11). Four studies observed increased consumption of tobacco in mixed sex group populations (B = 0.31, SE = 0.14, p < 0.03), in girls (OR 2.28, 95% CI 1.39–3.74; OR 1.53, 95% CI 1.13–2.06; OR 2.15, 95% CI 1.07–4.35) or boys (OR 3.04, 95% CI 1.16–7.95), whereas alcohol consumption was measured in 2 studies: in girls (OR 1.44, 95% CI 1.03–1.74) and in mixed sex study populations (B = 0.25, SE = 0.14; p < 0.5). Two studies described an increased substance dependence in girls (ß = 0.16; CI 0.06–0.26) and in mixed sex study population (OR = 10.61; p < 0.011).ConclusionThe low effect dimensions, limitations caused by the study design and the lack of consideration of confounders presuppose that such interpersonal violence cannot be considered as a risk factor. 相似文献

Experimental studies suggest that carotenoids and retinol may play a role in carcinogenesis, but epidemiological evidence is lacking. We investigated the prospective associations between plasma concentrations of major carotenoids and retinol, and overall and breast cancer risk. A nested case-control study included all first incident cancer cases diagnosed in the SU.VI.MAX cohort between 1994 and 2002 ( n = 159 cases, 1 matched control/case). Baseline plasma concentrations of carotenoids and retinol were measured by high-performance liquid chromatography. Conditional logistic regression was used to assess odds ratios for an increase of 0.1 μmol/L [odds ratio (OR)] and 95% confidence intervals (CI). Plasma β-carotene (OR = 0.95, 95% CI = 0.90–0.99, Ptrend = 0.04) and β-cryptoxanthin concentrations (OR = 0.89, 95% CI = 0.81–0.99, Ptrend = 0.03) were inversely associated with overall cancer risk. Plasma β-cryptoxanthin concentration was inversely associated with breast cancer risk (OR = 0.83, 95% CI = 0.71–0.96, Ptrend = 0.02). The OR between plasma lycopene concentration and overall cancer risk was 1.07 (0.99–1.15), Ptrend = 0.06. This association turned significant ( Ptrend = 0.01) when excluding cancer cases diagnosed during the first year of follow-up. This prospective study suggests an inverse association between plasma concentrations of β-cryptoxanthin and both overall and breast cancer risk, and an inverse association between β-carotene and overall cancer risk. The direct association between lycopene concentration and cancer risk deserves further investigation. 相似文献

Background Dysphagic older patients are prescribed texture modified food or fluids as treatment. The present study aimed to determine whether targeted feeding assistance using trained volunteers increased oral intake in elderly dysphagic patients. Method Individualized feeding assistance was given to patients who were diagnosed with dysphagia by a speech and language therapist. Data were collected between 08.00 h and 16.00 h and compared with previously collected data from dysphagic patients who received no targeted feeding assistance. Results The group with targeted assistance ( n = 16) had higher intakes of energy and protein from both meals and supplements combined compared to the controls ( n = 30); mean difference = 2327 kJ (554 kcal) (95% CI = 1294–3360 kJ; P < 0.001) and 28 g protein (95% CI = 13–41 g; P = 0.01). The assisted group ate more from meals only; mean difference = 1336 kJ (318 kcal) (95% Cl = 517–2155 kJ; P = 0.002) and 6 g of protein (95% Cl = 2–26 g; P = 0.02); and from nutritional supplements only, median difference = 1205 kJ (287 kcal) (95% CI = 613–1273 kJ; P = 0.0002) and 15 g protein (95% CI 6.9–15 g; P < 0.0001). Conclusion Nutritional intake can be improved by targeted feeding assistance in hospitalized elderly dysphagic patients on texture modified diets. 相似文献

Carbohydrate intake has been inconsistently associated with risk of prostate cancer. We review and quantitatively summarize the evidence from observational studies in a meta-analysis. We searched the PubMed database for observational studies related to the association of carbohydrate intake and prostate cancer risk up to December 25, 2013. Summary relative risks (RRs) were estimated by the use of a random effects model. We included 13 case-control studies with 4,367 cases and 6,205 controls, and 5 cohort studies with 3,679 cases and 74,115 participants in this meta-analysis. The summary RR of prostate cancer for the highest vs. the lowest carbohydrate intake was 1.06 [95% confidence interval (CI): 0.93–1.20, I 2 = 46.8%] for all included studies. In the subgroup analyses stratified by study design, the summary RRs for the highest vs. the lowest carbohydrate intake were 1.04 (95% CI: 0.87–1.23) for case-control studies and 1.06 (95% CI: 0.88–1.28) for cohort studies. For the 5 studies that reported results for advanced prostate cancer, the summary RR was 0.92 (95% CI: 0.71–1.20). This meta-analysis of observational studies indicates that there is no association between carbohydrate intake and prostate cancer risk. Further studies are needed to confirm our findings. 相似文献
