Excessive adiposity at low BMI levels among women in rural Bangladesh.

ABSTRACT: Asian populations have a higher percentage body fat (%BF) and are at higher risk for CVD and related complications at a given BMI compared with those of European descent. We explored whether %BF was disproportionately elevated in rural Bangladeshi women with low BMI. Height, weight, mid-upper arm circumference, triceps and subscapular skinfolds and bioelectrical impedance analysis (BIA) were measured in 1555 women at 3 months postpartum. %BF was assessed by skinfolds and by BIA. BMI was calculated in adults and BMI Z-scores were calculated for females <20 years old. Receiver operating characteristic (ROC) curves found the BMI and BMI Z-score cut-offs that optimally classified women as having moderately excessive adipose tissue (defined as >30 % body fat). Linear regressions estimated the association between BMI and BMI Z-score (among adolescents) and %BF. Mean BMI was 19·2 (sd 2·2) kg/m(2), and mean %BF was calculated as 23·7 (sd 4·8) % by skinfolds and 23·3 (sd 4·9) % by BIA. ROC analyses indicated that a BMI value of approximately 21 kg/m(2) optimised sensitivity (83·6 %) and specificity (84·2 %) for classifying subjects with >30 % body fat according to BIA among adults. This BMI level is substantially lower than the WHO recommended standard cut-off point of BMI ? 25 kg/m(2). The equivalent cut-off among adolescents was a BMI Z-score of -0·36, with a sensitivity of 81·3 % and specificity of 80·9 %. These findings suggest that Bangladeshi women exhibit excess adipose tissue at substantially lower BMI compared with non-South Asian populations. This is important for the identification and prevention of obesity-related metabolic diseases.

Project description:BackgroundRecent evidence suggests that diet inequities between men and women may have diminished within rural Bangladeshi households. However, this has not been directly tested with appropriate physiologic adjustments and it is unclear whether changes have occurred across socioeconomic strata. Understanding intrahousehold dietary patterns at different points on the income and food-security distribution in rural Bangladesh-particularly, within ultrapoor and farm households-is important for appropriate design of gender-sensitive and nutrition-sensitive interventions, which often target these groups.ObjectiveUsing 2012 and 2016 data, we aimed to examine gender differences in diet quantity and quality among ultrapoor and farm households in rural Bangladesh.MethodsThe study used baseline 24-h dietary data from 2 randomized control trials conducted in rural Bangladesh: the Transfer Modality Research Initiative (ultrapoor households) and the Agriculture, Nutrition, and Gender Linkages project (farm households). Ordinary least squares regressions with household-level fixed effects tested for gender differences among constructed diet measures, such as caloric intake, caloric adequacy ratio, dietary diversity score, global diet quality score, and probability of consuming moderate or high levels of healthy food groups.ResultsIn both samples, on average, women consumed fewer calories than men in the same households but consumed near equal or more in reference to their caloric needs. Women scored <1% lower than men on diet quality indicators and showed similar probabilities to men of consuming healthy foods. Most men and women in both samples were calorically inadequate (>60%) and recorded poor diet quality scores that indicated high risk of nutrient inadequacy and chronic disease (>95%).ConclusionsIn both ultrapoor and farm households, although men record higher intake quantities and diet quality scores, the apparent male advantage disappear when energy requirements and the magnitudes of difference are considered. Diets of men and women in these rural Bangladeshi households are equitable but suboptimal.

Project description:Background:The global development community has increasingly come to frame preventable maternal mortality and morbidity principally as a violation of women's basic human rights, necessitating a human rights-based approach to be appropriately addressed. In this article, we explore how human rights are understood and perceived in relation to maternal health at the local level in rural Bangladesh. This is essential given the momentum at the global level to promote rights and apply rights-based approaches to maternal health. Methods:A community-based, cross-sectional household survey was conducted in three upazilas (sub-districts) of Brahmanbaria district, Bangladesh in 2018. A total of 1367 women with a birth outcome in the past 12 months were interviewed. Descriptive statistics were used to report the awareness and perceptions of human rights related to maternal health. Multiple logistic regression was used to identify the associations between awareness and perceptions of human rights and background characteristics and, finally, with the use of skilled maternal health services. Results:Over two-thirds of women reported that they were aware that women have human rights related to maternal health. However, less than 10% were able to mention at least three specific human rights related to maternal health. Half of the women mentioned husbands as duty-bearers, while only 20% mentioned the government as a duty-bearer. One-third of women reported that they are able to realize their rights related to maternal health satisfactorily. Awareness and perceptions of human rights related to maternal health were significantly associated with higher educational attainment and wealth status. They were also associated with increased use of antenatal care. Conclusions:These findings suggest that interventions promoting the awareness of human rights related to maternal health would be appropriate within the communities of rural Bangladesh as part of a broader human rights-based approach to improving maternal health.
