Efficacy of a school-based education intervention on the consumption of fruits, vegetables and carbonated soft drinks among adolescents.

OBJECTIVES: To evaluate the efficacy of a school-based education intervention on the consumption of fruit, vegetables and carbonated soft drinks among adolescents. DESIGN: Cluster-randomised controlled trial. SETTING: Eight secondary schools from Dhaka, Bangladesh, participated in this trial and were randomly allocated to intervention (n 160) and control groups (n 160). PARTICIPANTS: A total of 320 students from 8th to 9th grades participated and completed the self-reported questionnaires at baseline, and at 8 and 12 weeks. The intervention included weekly classroom-based nutrition education sessions for students and healthy eating materials for students and parents. Repeated measures ANCOVA was used to assess the effects of the intervention. RESULTS: Daily fresh fruit intake was more frequent in the intervention (26 %) compared to the control group (3 %) at 12 weeks (p = 0·006). Participants from the intervention group also reported a significantly (P < 0·001) higher (49 %) proportion of fresh vegetable intake compared to the control group (2 %) at 12 weeks. Frequency of daily carbonated soft drinks intake decreased (25 %) in the intervention group at 12 weeks compared to baseline, while it remained unchanged in the control group; the interaction effect was observed significant (P = 0·002). CONCLUSION: Our school-based education intervention increased the daily frequency of fresh vegetables and fruit intake and decreased carbonated soft drink consumption among adolescents in the intervention group. There is a need for scaling up the intervention to engage students and empower them to develop healthy dietary habits.

Examining the Association between Sports Participation and Mental Health of Adolescents.

Sports participation has been linked to various health outcomes; however, there is scant literature exploring this relationship in developing countries. We used a mixed method approach to examine the association between sports participation and mental health of Bangladeshi adolescents (n = 320; 13-17 years; 59% boys) and to explore sports preferences and barriers to sports participation across genders. A survey collected team and non-team sports participation, depression, and life satisfaction. Focus groups (16 boys, 16 girls) explored preferences for, and barriers to, sports participation. Regression analysis showed that higher team and non-team sports participation were associated with lower depressive symptoms in boys (ß = -1.22, 95% CI:-2.55 to -0.10; ß = -2.50, 95% CI:-3.83 to -1.16, respectively), while greater participation in team sports was associated with less depression in girls (ß = -2.44, 95% CI:-4.63 to -0.24). Participation in team and non-team sports was positively associated with life satisfaction for boys and girls. Boys reported preferences for playing football and cricket, while girls favored skipping and running. Prolonged time on electronic devices was reported as barriers to sports participation in both genders. Furthermore, household chores, family restrictions, and unsafe environment were reported by girls. Participation in team sports may provide mental health benefits for both genders, while non-team sports may be more beneficial to boys than girls.

Prevalence and determinants of metabolic syndrome among newly diagnosed type 2 diabetic subjects according to different criteria.

BACKGROUND AND AIM: Metabolic syndrome (MS) is becoming a serious global public health problem. The prevalence of MS differs in different population by using different definitions. Present study aimed to find out the prevalence and determinants of MS among newly diagnosed type 2 diabetes (NDT2D) according to different criteria. SUBJECTS AND METHODS: This cross-sectional analytic study was conducted among 281 subjects selected purposively from the OPD of BIRDEM. Information on lifestyle factors and disease history were collected using a semi-structured questionnaire by face to face interview. The three definitions of MS used in this study are from the International Diabetes Federation (IDF), a modified version of the ATP III criteria for Asian populations (modified ATP III) and World Health Organization (WHO) criteria. Adjusted odds ratio and confidence limit were generated through logistic regression. RESULTS: The overall prevalence of metabolic syndrome among the study subjects according to modified ATPIII, WHO and IDF criteria were 79% (95% CI: 74.2-83.8), 81% (95% CI: 76.4-85.6) and 68% (95% CI: 62.6-73.5) respectively. The prevalence of metabolic syndrome among female were higher compared to males in all the criteria's. Female gender (OR=5.93), family history of diabetes (OR=1.92), overweight (OR=6.2), and obesity (OR=5.13) were found as important confounders associated with metabolic syndrome. CONCLUSION: The prevalence of the metabolic syndrome among NDT2D is considerably higher in our population which may indicate considerable risk of cardiovascular diseases in future. Female gender, family history of diabetes, overweight and obesity are important confounders of MS in this population.

Anthropometric indices of obesity and type 2 diabetes in Bangladeshi population: Chandra Rural Diabetes Study (CRDS).

BACKGROUND: Obesity is a risk factor for type 2 diabetes (DM); however, no study has specially assessed the anthropometric indices as predictors of diabetes in rural Bangladeshi population. OBJECTIVE: To identify markers for diabetes through body mass index (BMI), waist circumference (WC), waist hip ratio (WHR) and waist height ratio (WHtR) and identify the optimal cut-off values suitable for Bangladeshi adult population. METHODS: A total of 2293 subjects aged ≥20 years from rural Bangladesh were randomly recruited to participate in a population-based, cross sectional survey. Age adjusted data for anthropometric indices and diabetes risk were assessed and their relationships were examined. RESULTS: Age adjusted prevalence of DM in men and women were 9.5% and 7.0%, respectively. Both men and women with DM had a higher rate of general obesity (defined by BMI) and central obesity (defined by WC, WHR and WHtR) than non-diabetic subjects. In both men and women the most sensitive indice was WHR for predicting DM. The appropriate cut-offs values for WHR to predict DM in men and women were 0.93 and 0.87, respectively. WC of 82 cm for both sexes was appropriate to predict DM. Those of BMI and WHtR were 21.2 kg/m2, 21.8 kg/m2 and 0.53, 0.54 in men and women, respectively. CONCLUSIONS: Compared with BMI, measures of central obesity, WHR, WC, WHtR showed a better association with the risk of DM for both sexes in rural Bangladeshi population. Follow-up studies are needed for validifying these cut-offs values.

Pattern and predictors of dyslipidemia in patients with type 2 diabetes mellitus.

Dyslipidemia is a major risk factor for macro-vascular complications in patients with type 2 diabetes mellitus (T2DM). Present study explored pattern and predictors of dyslipidemia in Bangladeshi T2DM patients. The cross-sectional study is conducted among 366 consecutive eligible T2DM patients aged >30 years, BIRDEM diabetic hospital, during July-to-December 2010. Physical examination, diabetic profile, lipid profile and serum createnine was performed. Adjusted odds ratio and confidence limit were generated through binary logistic regression. Most frequent form (59.3%) of dyslipidemia is low HDL. Duration of T2DM is significantly correlated with TC (P<0.05), HDL (P<0.05) and LDL (P<0.05) in both male and female. Glycemic control in terms of HbA1c >7% appeared as predictor of dyslipidemia (P<0.01). Duration T2DM is associated with increased risk of having higher TC (P<0.05), LDL (P<0.05) and lower HDL (P<0.01) and does not seem to affect triglyceride (P>0.05). T2DM with comorbid hypertension seems to predict hyper tri-glyceridemia and lower HDL. Both TC-HDL ratio and LDL-HDL ratio appeared as good predictor of all four parameters of dyslipidemia (P<0.01). The characteristic features of diabetic dyslipidemia are low HDL, high triglyceride and LDL cholesterol level. Low HDL level is the most frequent type of abnormality. Poor glycemic control, prolonged duration, coexisting hypertension predicts dyslipidemia in T2DM.

Factors associated with knowledge about breastfeeding among female garment workers in Dhaka city.

BACKGROUND: Knowledge about breastfeeding among women is very important for healthy children. The present study aims to determine the level of knowledge and factors associated with knowledge on breastfeeding among female garment workers in a selected garment factory in Dhaka city. METHODS: A cross-sectional study was conducted among 200 female garment workers in the reproductive age group (15-49 years). Data were collected through a pre-tested questionnaire using the face-to-face interview method. Bivariate and multivariate analysis was done to determine the association between sociodemographic variables and knowledge on breastfeeding. RESULTS: The study showed that, overall the level of knowledge regarding breastfeeding is very poor (88%) among the study subjects. Most of the respondents have very poor knowledge regarding advantages of exclusive breastfeeding (89%) and breastfeeding (100%). In contrast, a majority have good knowledge on duration of exclusive breastfeeding (74%) and breastfeeding (66%). No significant association was found between the knowledge score of breastfeeding with remaining socio-demographic variables like age, marital status, family income and expenditure. Education is significantly (p<0.001) associated with a higher total knowledge score of breastfeeding. Women with secondary level of education had a significantly higher (p<0.001) level of total knowledge score than other categories (illiterate, primary and higher secondary) of education. CONCLUSION: A large proportion of female garment workers had inadequate knowledge regarding breastfeeding. It is also important that health education on breastfeeding is urgently provided to the female garments workers of Bangladesh.

Risk factors of diabetic retinopathy in Bangladeshi type 2 diabetic patients.

AIMS: To determine the risk factors associated with diabetic retinopathy (DR) in Bangladeshi type 2 diabetic subjects. METHODS: A cohort of 977 type-2 diabetic patients was recruited retrospectively based on hospital records in 2008, who were naïve type-2 diabetes during 1993. Data on diabetes and lipid profile with serum creatinine and biophysical measures were obtained at baseline, 5, 10 and 15 years. DR was diagnosed by retinal color photography. Generalized linear models were used to assess the associations of clinical, biochemical and anthropometric variables with retinopathy at three follow-up. Cumulative exposures were determined based on average exposure to individual attribute. IRR and 95% CI were generated through Poisson regression model, adjusting for age-at-diagnosis of diabetes, baseline BMI, end-line waist-to-hip ratio and present physical activity status. RESULTS: DR patients had significantly poorer glycemic control at all three follow-ups. Age, residence, physical activity, serum creatinine and hypertension appeared as independent risk factors for DR in all three follow-up points. Poisson regression model identified glucose deregulation (IRR 1.8; CI 1.5-2.1), hypertension (IRR 1.5; CI 1.2-1.8) and raised serum creatinine (IRR 1.9; CI 1.5-2.3) as significant predictors for DR adjusted for possible confounders. Work related moderate-to-heavy physical activity (IRR 0.2; CI 0.1-0.3) appeared as protective. CONCLUSIONS: Along with poor glycemic control, hypertension, nephropathy are independent risk factor retinopathy.
