This study examined differences in diet quality by meal type, location, and time of week in youth with type 1 diabetes mellitus. A sample of youth with type 1 diabetes mellitus (n=252; 48% female) age 8 to 18 years (mean±standard deviation=13.2±2.8 years) with diabetes duration ≥1 year (mean±standard deviation=6.3±3.4 years) completed 3-day diet records. Multilevel linear regression models tested for differences in diet quality indicators by meal type, location, and time of week (weekdays vs weekends). Participants showed greater energy intake and poorer diet quality on weekends relative to weekdays, with lower intake of fruit and vegetables, and higher intake of total and saturated fat. Differences in diet quality were seen across meal types, with higher nutrient density at breakfast and dinner than at lunch and snacks. Participants reported the highest whole-grain and lowest fat intake at breakfast, but higher added sugar than at lunch or dinner. Dinner was characterized by the highest fruit intake, lowest added sugar, and lowest glycemic load, but also the highest sodium intake. The poorest nutrient density and highest added sugar occurred during snacks. Diet quality was poorer for meals consumed away from home than those consumed at home for breakfast, dinner, and snacks. Findings regarding lunch meal location were mixed, with higher nutrient density, lower glycemic load, and less added sugar at home lunches, and lower total fat, saturated fat, and sodium at lunches away from home. Findings indicate impacts of meal type, location, and time of week on diet quality, suggesting targets for nutrition education and behavioral interventions.  相似文献

Objective The purpose of this analysis was to assess to what extent sociodemographic and psychosocial characteristics predict consumption of fruits and vegetables in women served by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).Design Baseline survey data were analyzed for women enrolled in the Maryland WIC 5 A Day Promotion Program, a study sponsored by the National Cancer Institute. Sociodemographic variables included age, race, education, marital status, working status, pregnancy status, and smoking status. Psychosocial variables included self-efficacy, knowledge, attitudes, social support, and perceived barriers to consuming 5 or more servings daily of fruits and vegetables.Subjects/setting Analyses are based on 3,122 women enrolled at 15 WIC sites in Baltimore and 6 counties in Maryland.Statistical analyses performed Because psychosocial characteristics were measured on different scales and varied in dispersion, we standardized scores for these variables. Multiple regression analyses were then performed to assess contributions of the sociodemographic variables and the standardized psychosocial variable scores to the variance in consumption of fruits and vegetables.Results Sociodemographic variables were not powerful predictors of fruit and vegetable consumption. In contrast, an increase of 1 standard deviation in self-efficacy resulted in a mean increase of 0.76 servings, and an increase of 1 standard deviation in perceived barriers resulted in a decrease of 0.50 servings. About 21% of the variance in consumption was explained by all of the variables examined.Applications Dietitians and intervention programs should focus on increasing clients’ self-efficacy, positive attitudes, and knowledge relating to fruits and vegetables while trying to reduce perceived barriers to consumption of fruits and vegetables.

The present study aimed to examine the factors associated with increased Mediterranean diet (MD) adherence among a sample of Italian adolescents. A cross-sectional survey was conducted on 1135 students (13–16 years) attending 13 secondary schools of Sicily, southern Italy. Validated instruments were used for dietary assessment and the KIDMED score to assess adolescents’ adherence to the MD. A higher adherence to the MD was associated with high socioeconomic status (Odds Ratio [OR] 1.53, 95% Confidence Interval [CI]: 1.03–2.26) and high physical activity (OR 1.19, 95% CI: 1.02–1.70), whereas lower adherence was associated with living in an urban environment (OR 0.65, 95% CI: 0.44–0.97) and being obese (OR 0.59, 95% CI: 0.37–0.94). The adolescents’ KIDMED scores were inversely associated with adolescents’ intake of sweets, fast foods, fried foods, and sugary drinks, and directly with fruit, vegetables, pasta, fish, and cheese intakes. Urban-living adolescents were less likely to eat fruit and more prone to consume meat, sugary drinks, and fast food than rural-living adolescents. The latter were more likely to eat sweets and snacks. A general poor quality of food consumption in Italian adolescents away from the MD was reported, especially among those living in urban areas.  相似文献

The prevalence of type 2 diabetes (T2D) is increasing rapidly worldwide. A healthy diet supporting the control of energy intake and body weight has major importance in the prevention of T2D. For example, a high intake of whole grain foods (WGF) has been shown to be inversely associated with risk for T2D. The objective of the study was to estimate the expected health economic impacts of increased WGF consumption to decrease the incidence of T2D in the Finnish adult population. A health economic model utilizing data from multiple national databases and published scientific literature was constructed to estimate these population-level health economic consequences. Among the adult Finnish population, increased WGF consumption could reduce T2D-related costs between 286€ and 989€ million during the next 10-year time horizon depending on the applied scenario (i.e., a 10%-unit increase in a proportion of daily WGF users, an increased number (i.e., two or more) of WGF servings a day, or alternatively a combination of these scenarios). Over the next 20–30 years, a population-wide increase in WGF consumption could lead to much higher benefits. Furthermore, depending on the applied scenario, between 1323 and 154,094 quality-adjusted life years (QALYs) could be gained at the population level due to decreased T2D-related morbidity and mortality during the next 10 to 30 years. The results indicate that even when the current level of daily WGF consumption is already at a relatively high-level in a global context, increased WGF consumption could lead to important health gains and savings in the Finnish adult population.  相似文献

(1) Background: The present study aimed to investigate the association between home-related factors, community environmental factors, and sugar-sweetened beverages (SSBs) intake among Northeastern Chinese children. (2) Methods: Cross-sectional. Children with complete data were included in the analysis (n = 901). A questionnaire modified according to BEVQ-15 measured the intake of SSBs. Logistic regression was applied to determine the factors associated with the consumption of SSBs. IBM SPSS Statistics 23.0 was applied to perform all statistical analyses. (3) Results: The mean total amount of SSBs consumed on a weekly basis was 2214.04 ± 2188.62 mL. Children’s weekly pocket money, frequency of SSBs purchase, SSBs availability at home, the number of accessible supermarkets, and frequency of weekly visits to convenience stores were all found to be associated with a high intake of SSBs among all children. Among children of normal weight, the findings indicated that weekly pocket money, SSBs availability at home, and number of accessible supermarkets were associated with a high SSBs intake. At the same time, frequency of SSBs purchase, mother’s SSBs intake, and frequency of weekly visits to convenience stores were associated with a high SSBs intake among children with obesity. (4) Conclusions: Given the potential negative health effects of high SSBs intake, it is crucial to pay attention to home-related factors and community environment.  相似文献

Most young adults do not consume recommended levels of fruits and vegetables (F/V), and interventions to increase F/V-related behaviors among this understudied population are needed. Therefore, it is important to identify correlates of F/V intake among young adults to guide intervention development. This cross-sectional study used data from an online survey to identify factors related to young adults’ F/V purchasing, preparation, and consumption, and to explore between-factor relationships using mediation analysis. In 2010, 1,201 college students in Minnesota completed questionnaires assessing F/V behaviors as well as perceptions of F/V-related individual, social, and environmental factors. Factor analysis identified questionnaire items assessing similar constructs. Seven factors were identified (personal barriers, F/V knowledge, family, friends, neighborhood, access barriers, and campus) and evaluated for relationships with F/V purchasing, preparation, and consumption using linear regression. Results revealed that perceived personal barriers (eg, lacking cooking skills) were inversely related to all F/V outcomes. Perception that family and friends eat healthfully and neighborhood access to F/V were positively related to all outcomes. Individual-, social-, and environment-level perceptions were related to purchasing, preparation, and consumption, and the effects of these factors were similar when accounting for mediated effects. Factors at all three levels and the ways in which these various factors operate together may be important to consider in future efforts to improve F/V behaviors among young adults.  相似文献

In 2005-2006, Réunion Island in the Indian Ocean reported approximately 266,000 cases of chikungunya; 254 were fatal (case-fatality rate 1/1,000). India reported 1.39 million cases of chikungunya fever in 2006 with no attributable deaths; Ahmedabad, India, reported 60,777 suspected chikungunya cases. To assess the effect of this epidemic, mortality rates in 2006 were compared with those in 2002-2005 for Ahmedabad (population 3.8 million). A total of 2,944 excess deaths occurred during the chikungunya epidemic (August-November 2006) when compared with the average number of deaths in the same months during the previous 4 years. These excess deaths may be attributable to this epidemic. However, a hidden or unexplained cause of death is also possible. Public health authorities should thoroughly investigate this increase in deaths associated with this epidemic and implement measures to prevent further epidemics of chikungunya.  相似文献

Objective: The aim of our study was to compare the effects of a vegetarian and a conventional diet on thigh adipose tissue distribution in subjects with type 2 diabetes (T2D).

Methods: Seventy-four subjects with T2D were randomly assigned to either follow a vegetarian diet (V, n = 37) or a control group who followed an isocaloric conventional anti-diabetic diet (C, n = 37). Both diets were calorie restricted (?500 kcal/day). To measure insulin sensitivity, the hyperinsulinemic (1 mU.kg?1.min?1) isoglycemic clamp was conducted. β-Cell function was assessed using a mathematical model after a test meal. Magnetic resonance imaging of the thigh was performed. All subjects were examined at 0, 3, and 6 months. Statistical analyses were performed using repeated measures analysis of variance and a multivariate regression model.

Results: Greater reduction was observed in total leg area in V (?13.6 cm2 [95% confidence interval [CI], ?14.2 to ?12.9] in V vs ?9.9 cm2 [95% CI, ?10.6 to ?9.2] in C; Gxt p < 0.001). The reduction in subcutaneous fat was comparable in response to both diets (Gxt, p = 0.64). Subfascial fat was reduced only in response to a vegetarian diet (?0.82 [95% CI, ?1.13 to ?0.55] cm2 in V vs ?0.44 [95% CI, ?0.78 to +0.02] cm2 in C; Gxt, p = 0.04). The reduction in intramuscular fat tended to be greater in response to a vegetarian diet (?1.78 [95% CI, ?2.26 to ?1.27] cm2 in V vs ?0.57 [95% CI, ?1.06 to ?0.09] cm2 in C; Gxt, p = 0.12). Changes in subcutaneous and subfascial fat correlated with changes in glycated hemoglobin (HbA1c), fasting plasma glucose, and β-cell insulin sensitivity. After adjustment for changes in body mass index (BMI), correlations remained significant for changes in fasting plasma glucose and β-cell insulin sensitivity and with changes in triglycerides.

Conclusions: Our data indicate the importance of both subcutaneous and subfascial fat in relationship to glucose and lipid metabolism.

As nutrient-dense fruits, mangoes are commonly consumed globally and are important sources of nutrients in the diet. Nonetheless, mangoes remain relatively under-consumed in the United States. The objective of the present analysis was to examine nutrient intakes, diet quality, and health outcomes using data from NHANES 2001–2018 in children and adult mango consumers (n = 291; adults n = 449) compared with mango non-consumers (children n = 28,257; adults n = 44,574). Daily energy and nutrient intakes were adjusted for a complex sample design of NHANES using appropriate weights. Mango consumption was not associated with daily energy intake, compared with non-consumption, in both children and adults. Children consuming mangoes had a significantly lower daily intake of added sugar, sodium, total fat, and a higher intake of dietary fiber, magnesium, potassium, total choline, vitamin C, and vitamin D, compared with non-consumers. In adults, mango consumers had significantly higher daily intakes of dietary fiber, magnesium, potassium, folate, vitamin A, vitamin C, and vitamin E and significantly lower intakes of added sugar and cholesterol, compared with non-consumers. Mango consumption was also associated with a better diet quality vs. mango non-consumers (p < 0.0001). Mango consumption in adolescents was associated with lower BMI z-scores, compared with non-consumption. In adults, BMI scores, waist circumference, and body weight were significantly lower only in male mango consumers when compared with mango non-consumers. The current results support that mango consumption is associated with improved nutrient intakes, diet quality, and certain health outcomes. Thus, dietary strategies that aim to increase mango consumption in the American population should be evaluated as part of future dietary guidance.  相似文献

BackgroundDiabetes mellitus remains the leading cause of end-stage renal disease in most countries in the world. In Ethiopia, renal complications of diabetes may remain unrecognized due to limited diagnostic resources. As a result, the prevalence of chronic kidney disease among adult diabetics in Ethiopia has not been well described. Hence, this study was aimed at assessing the prevalence of chronic kidney disease and associated factors among diabetic patients who attended the federal police hospital diabetic clinic in Addis AbabaMethodsA cross-sectional study was conducted among 362 Diabetes Mellitus. Data were collected using face-to-face interviewing questionnaires and analyzed using SPSS version 21.0. Binary logistic regression analyses were performed to identify predictors.ResultsThe prevalence of chronic kidney disease diagnosed by Cockcroft-Gault equation and Modification of Diet in Renal Disease equation was 14.6% and 7.7% respectively. This finding shows the prevalence of chronic kidney disease among Diabetic patients was low. Age 50–59 years [(AOR= 4.0; 95% CI:(1.2, 13)] by Cockroft-Gault equation (CG), age 60–69 years [(AOR=5.8 95% CI:(1.5,21.0)] by Modification of Diet in Renal Disease (MDRD) and (AOR;22.9 95%CI:7.1,74.2) by CG, age 70 years and above (AOR=4.7; 95 CI: 1.1, 19.7) by MDRD and (AOR= 22.9; 95%CI:7.1,74.2) by CG, BMI (AOR=0.2; 95% CI:0.1,0.4) by CG, and previous kidney disease (AOR=6.2 95%CI:2.0,8.4) by MDRD and (AOR;4.6 95%CI:1.9,10.8) C-G equation have a significant association with chronic kidney disease after an adjustment done.ConclusionThe prevalence of chronic kidney disease among Diabetic patients in this study was lower. Age, BMI, and previous recurrent kidney disease were associated with chronic kidney disease. Preventive measures like giving health education and screening of patients with risk factors should get more attention.  相似文献

Low-socioeconomic-status (SES) Latinos are disproportionately represented among the 78 million obese Americans. Tailored behavioral weight-loss interventions show promise, but there is limited adaptation to lower-SES Latino immigrants. This study provides guidance for tailoring obesity-reduction strategies for this population by evaluating food security, educational community resource utilization, education level, depression, sex, and length of US residence as predictors of diet and physical activity. The cross-sectional study used baseline data collected in July 2009 through September 2010 for a weight-loss trial among lower-SES obese (body mass index 30 to 55) Latino immigrants who were enrolled at a community health clinic (n=207). Physical activity was measured using 7-day pedometer recording. Dietary intake was measured using an interviewer-administered food frequency questionnaire. Factors assessed by questionnaire included education community resource use (nutrition and physical activity classes), education level, US residence (years), food security, and depressive symptoms. Data were analyzed using multivariate-adjusted linear regression models. More than one third of participants were sedentary (<5,000 steps/day), and 41% had low fruit and vegetable intake (<5 servings/day). In multivariate-adjusted models, educational community resource use, male sex, less education, fewer depressive symptoms, and shorter US residence time were associated with more physical activity (all, P≤0.05). Educational community resource use was positively associated with fruit and vegetable intake (P=0.05). Male sex was associated with more sweet-beverage intake (P=0.02) and fast-food intake (P=0.04). Fewer depressive symptoms were associated with lower sweet-beverage intake (P=0.05). In conclusion, obesity-reduction strategies among low-SES Latino immigrants might effectively emphasize educational community resource use and interventions tailored for psychosocial and sociodemographic characteristics.  相似文献

High consumption of sugar-sweetened beverages (SSBs) is associated with a higher risk of cardiovascular disease (CVD). The last report on the prevalence of SSBs consumption in Czechia was 17 years ago, an updated analysis will enable the design of appropriate public health policies. This study aimed to determine the prevalence of SSBs consumption in a Czech city during 2020 and 2022, and its association with cardiometabolic biomarkers, behavioral risk factors, and socioeconomic determinants. A total of 730 participants (33 to 73 years) were assessed from a random population-based survey. SSBs consumption was evaluated using two methods: by calorie amount, with a 24 h dietary recall, and by frequency, with a food frequency questionnaire. By calorie amount, the prevalence of SSBs consumption was none: 52.5%, low: 30.0%, and moderate–high: 17.5%; by frequency was never: 16.0%, occasionally: 64.1%, and daily: 19.9%. SSBs intake was higher in men (p < 0.001) and younger participants (p = 0.001). Men consuming daily had higher waist circumference and visceral fat area compared to both occasional and never consumers. Higher SSBs consumption was associated with low household income, middle education level, and high total energy intake. In total, 20% drank SSBs daily and 17.5% of participants consumed moderate–high calorie amounts of SSBs. These results represent an increase in the prevalence of SSBs consumption in the last two decades. Public health policies should target men of younger age and people with low education and income.  相似文献

In an epidemiological study carried out in three textile mills at Ahmedabad, India, 929 workers were examined from the spinning departments. The mean prevalence of byssinosis in the blow section was 29.62%, whereas in the card section it was 37.83%. The concentrations of cotton dust (dust less fly) were high in the blow and card sections (4.00 mg/m3 in the blow and 3.06 mg/m3 in the card section). This study suggests that the prevalence of byssinosis is not low in the textile mills of India as reported in many earlier Indian studies.  相似文献

Stillbirth is a globally significant public health problem with many medical causes. There are also indirect causal pathways including social and cultural factors which are particularly salient in India’s traditional society. The purpose of this study was to explore women’s perceptions of stillbirth and to determine how issues of gender and power, social support, coping efforts, and religious beliefs influence perinatal grief outcomes among poor women in rural Chhattisgarh, India. Structured interviews were done face-to-face in 21 randomly selected villages among women of reproductive age (N = 355) who had experienced stillbirth (n = 178) and compared to those who had not (n = 177), in the Christian Hospital, Mungeli catchment area. Perinatal grief was significantly higher among women with a history of stillbirth. Greater perinatal grief was associated with lack of support, maternal agreement with social norms, and younger maternal age. These predictors must be understood in light of an additional finding—distorted sex ratios, which reflect gender discrimination in the context of Indian society. The findings of this study will allow the development of a culturally appropriate health education program which should be designed to increase social support and address social norms, thereby reducing psychological distress to prevent complicated perinatal grief. Perinatal grief is a significant social burden which impacts the health women.  相似文献
