Prevalence, inequality and associated factors of overweight/obesity among Bangladeshi adolescents aged 15-19 years.

BACKGROUND: The objective of the current study was to estimate the prevalence and associated factors of overweight/obesity among Bangladeshi adolescents aged 15-19 y and to identify whether wealth-related inequality exists for overweight/obesity among Bangladeshi older adolescents. METHODS: We analyzed publicly available national representative secondary data from the 2019-2020 Bangladesh Adolescent Health and Wellbeing Survey. This cross-sectional survey was carried out among 18 249 adolescents aged 15-19 y regardless of their marital status using a two-stage stratified sampling technique (the data of 9128 eligible adolescents were included in this analysis). The WHO reference population for body mass index-for-age (1+Z score) was considered as overweight/obesity. RESULTS: We found that girls had significantly (p<0.05) higher prevalence of overweight/obesity (11.63%) than boys (8.25%); however, their biological sex as well their age were not significantly associated with higher odds of overweight/obesity. Those who were in their higher grade (grade 11 and higher) in the school and had been exposed to media were more likely (1.67 and 1.39 times, respectively) to be overweight/obesity compared with primary grade (0-5) and those who experienced no media exposure, respectively. Inequality analysis revealed that adolescents belonging to wealthy households had significantly higher rates of overweight/obesity than those in poorer households (concentration index=0.093). CONCLUSIONS: The study exhibited the multifaceted nature of overweight/obesity among Bangladeshi older teenagers, revealing that their school grade, exposure to media content and wealth-related inequality emerged as significant contributing factors. The findings underscore the urgent need for targeted interventions and public health strategies to address the escalating burden of overweight and obesity in this age group.

Factors associated with the utilization of reproductive health services among the Bangladeshi married women: Analysis of national representative MICS 2019 data.

OBJECTIVES: We calculated the prevalence of reproductive health services utilization among the currently married non-pregnant women in Bangladesh and investigated its association with demographics and socio-economic factors. METHODS: Publicly available secondary country representative 2019 Multiple Indicator Cluster Survey (MICS) dataset was analyzed. A two-stage stratified random sampling technique was followed, and all administrative districts (N=64) of Bangladesh were covered in the MICS 2019. Contraceptive use, antenatal care and skilled birth attendant were considered as utilization of reproductive health services and both crude and adjusted Odd Ratio (OR) were reported using a total of 8917 (weighted) data. RESULTS: In Bangladesh, 36.9% of married non-pregnant women utilized all three reproductive health services. However, at disaggregated level, contraceptive use (66.9%), antenatal care (83%) and skilled birth attendant (59.3%) were found 2-3 folds higher then cumulative prevalence. Increased likelihood of utilization of reproductive health services (either combined or at individual services) was observed among those women who had higher education [AOR= 2.63, 95% CI 1.99 to 3.47], belong to wealthy families [AOR= 2.46, 95% CI 1.94 to 3.12], residing in urban areas [AOR= 1.33, 95% CI 1.14 to 1.54], having a smaller number of children [AOR= 1.53, 95% CI 1.25 to 1.87], and exposure to media [AOR= 1.44, 95% CI 1.26 to 1.63]. CONCLUSION: Around one-third of Bangladeshi married women received combined contraceptive use, antenatal care and skilled birth attendant reproductive health services; however, variation exist at the individual service level. Targeted public health campaign focusing on women education and media advertisement may increase the utilization.

Relationship of sleep pattern and snoring with chronic disease: findings from a nationwide population-based survey.

OBJECTIVES: To investigate the association of total sleep time and presence or absence of snoring with chronic disease among the Bangladeshi adult population. DESIGN: Cross-sectional survey. SETTING: Urban and rural Bangladesh. PARTICIPANTS: A total of 12,338 men and women aged ≥35 years. MEASUREMENTS: Total sleep time was considered as the total hours of sleep in 24 hours. Furthermore, sleep time was categorized into <7, 7-9, and >9 hours according to National Sleep Foundation (2015) guidelines. Self-reported snoring history was captured and corroborated with their respective sleep partner/spouse in more than 80% cases. Registered physician-diagnosed current and/or previous cases of hypertension, diabetes, coronary heart disease, cancer, stroke, chronic obstructive pulmonary disease, and any other chronic conditions were counted. RESULTS: Overall prevalence of at least 1 chronic disease in our study population was around 18%: men (15.4%) and women (20.0%). Hypertension has the highest prevalence (overall: 12.7%, men: 12.2%, women: 15%) followed by diabetes (4.9%), coronary heart diseases (3.2%), stroke (1.8%), chronic obstructive pulmonary disease (0.9%), and cancer (any type: 0.1%). Sleep pattern and snoring are significantly associated with all individual chronic disease except cancer. Sociodemographic, behavioral, and lifestyle variables were adjusted, and inadequate total sleep time (<7 hours) and snoring (yes/no) showed significant association with chronic disease status (risk ratio = 1.11, 95% confidence interval 1.00-1.22 and risk ratio = 1.20, 95% confidence interval 1.11-1.29, respectively). CONCLUSION: Inadequate sleep and snoring are independently associated with chronic disease in Bangladeshi adult population and perhaps elsewhere.

An outline of anemia among adolescent girls in Bangladesh: findings from a cross-sectional study.

BACKGROUND: Anemia is a significant wide spread public health threat especially among the adolescent girls who are more vulnerable towards low level of hemoglobin particularly of low and middle income countries (LMICs). We investigated the prevalence of anemia among the adolescent girls (10-19 years) in Bangladesh and its socio-demographics distribution. METHODS: We collected data digitally in ODK platform from a sub-sample of a nationwide cross-sectional survey of 1314 adolescent girls in 2015. Capillary blood hemoglobin level was estimated using HemoCue®; anthropometric measurements through standardized procedure and details socio-demographic information were captured and analyzed. Malnutrition was defined as BMI-for-age Z-score below -2SD (BAZ < -2SD), measured in WHO-AnthroPlus. Univariate analysis followed by multiple logistic regression were performed to examine the association between socio-demographic variables and anemia, while controlling the effect of potential confounding variables. RESULTS: Overall, 51.6% girls were suffering from any form of anemia (non-pregnant-Hb < 12 g/dl; pregnant-Hb < 11 g/dl) while 46% were mildly (non-pregnant-Hb: 10-11.9 g/dl; pregnant-Hb: 10-10.9 g/dl) and 5.4% were moderately (Hb: 7-9.9 g/dl) anemic while only 0.2% were severely anemic. After controlling for relevant covariates in multiple logistic regression model, malnutrition (AOR: 1.42, 95% CI = 1.0-2.10, p-value = 0.083), non-pregnancy (AOR: 6.10, 95% CI = 2.70-13.78, p-value < 0.001), and households with bottom wealth quintile (AOR: 1.54, 95% CI = 1.03-2.30, p-value = 0.037) were identified as significant risk factors of anemia among adolescent girls of Bangladesh. CONCLUSIONS: Higher number of adolescent girls are still suffering from anemia in Bangladesh and non-pregnant adolescent girls contributed the most. Immediate, long term and sustainable public health intervention would require to combat the situation.

A Review of Groundwater Arsenic Contamination in Bangladesh: The Millennium Development Goal Era and Beyond.

Arsenic contamination in drinking water has a detrimental impact on human health which profoundly impairs the quality of life. Despite recognition of the adverse health implications of arsenic toxicity, there have been few studies to date to suggest measures that could be taken to overcome arsenic contamination. After the statement in 2000 WHO Bulletin that Bangladesh has been experiencing the largest mass poisoning of population in history, we researched existing literature to assess the magnitude of groundwater arsenic contamination in Bangladesh. The literature reviewed related research that had been initiated and/or completed since the implementation of the Millennium Development Goals (MDGs) under four domains: (1) extent of arsenic contamination; (2) health consequences; (3) mitigation and technologies and (4) future directions. To this means, a review matrix was established for analysis of previous literature based on these four core domains. Our findings revealed that several high-quality research articles were produced at the beginning of the MDG period, but efforts have dwindled in recent years. Furthermore, there were only a few studies conducted that focused on developing suitable solutions for managing arsenic contamination. Although the government of Bangladesh has made its population's access to safe drinking water a priority agenda item, there are still pockets of the population that continue to suffer from arsenic toxicity due to contaminated water supplies.

How many hours do people sleep in Bangladesh? A country-representative survey.

This study investigated total sleep time in the Bangladeshi population and identified the proportion of the population at greater risk of developing chronic diseases due to inadequate sleep. Using a cross-sectional survey, total sleep time was captured and analysed in 3968 respondents aged between 6 and 106 years in 24 (of 64) districts in Bangladesh. Total sleep time was defined as the hours of total sleep in the previous 24 h. We used National Sleep Foundation (2015) guidelines to determine the recommended sleep hours in different age categories. Less or more than the recommended total sleep time (in hours) was considered 'shorter' and 'longer' sleep time, respectively. Linear and multinomial logistic regression models were used to determine the relationship between demographic variables and estimated risk of shorter and longer total sleep time. The mean (±standard deviation) total sleep time of children (6-13 years), teenagers (14-17 years), young adults and adults (18-64 years) and older adults (≥65 years) were 8.6 (±1.1), 8.1 (±1.0), 7.7 (±0.9) and 7.8 (±1.4) h, respectively, which were significantly different (P < 0.01). More than half of school-age children (55%) slept less than, and 28.2% of older adults slept longer than, recommended. Residents in all divisions (except Chittagong) in Bangladesh were less likely to sleep longer than in the Dhaka division. Rural populations had a 3.96× greater chance of sleeping for a shorter time than urban residents. The Bangladeshi population tends to sleep for longer and/or shorter times than their respective recommended sleep hours, which is detrimental to health.
