Prevalence of obesity in a rural Asian Indian (Bangladeshi) population and its determinants

Abstract

BackgroundObesity has reached epidemic proportions worldwide including Bangladesh. To assess the prevalence and associated factors of general and central obesity in a rural Bangladeshi population based on newly proposed cut off level for Asian population.Methods2293 subjects aged ≥20 years from rural Bangladesh were randomly recruited to participate in a population-based, cross sectional survey, conducted in 2009. Both socio-demographic and anthropometric measurements were recorded. Age adjusted data for anthropometric indices were examined.ResultsThe age standardized prevalence of overweight (BMI 23-24.9 kg/m2) and obesity (BMI ≥25 kg/m2) were 17.7 (95 % confidence interval (CI): 16.1, 19.2 %) and 26.2 % (95 % CI: 24.4, 27.9 %), respectively. The age standardized prevalence of central obesity based on WC (M ≥90 & F ≥80 cm) and WHR (M ≥0.90 & F ≥0.80) were 39.8 % (95 % CI: 37.9, 41.7 %) and 71.6 % (95 % CI: 69.8, 73.4 %) respectively. The result shows that prevalence of central obesity was more in female than male. Study shows middle age, medium and high socioeconomic status (SES), low education levels, physical inactivity, high consumption of carbohydrate, protein and fat, were significant risk indicators for general and central obesity. Smoking was shown as protective factor for both general and central obesity.ConclusionsIn rural Bangladeshi population, the prevalence of both general and central obesity was high among both sexes with the use of newly proposed cut off points for Asian population. Gender, diet, physical activity, education levels and SES were associated with the increase prevalence of obesity.

Excesso de peso em idosos rurais: associação com as condições de saúde e qualidade de vida

“…It is inferred that greater schooling possibly favors the process of understanding the nutritional status, contributing to reduce overweight conditions. Previous studies conducted in Brazil 8 and in the world 25,26 corroborate with this hypothesis by identifying that schooling was an indicator of risk for obesity in the elderly. However, while this aspect was not the focus of research, this study showed similar percentages between the groups.…”

“…Unlike these findings, Minas Gerais evidenced a higher share of overweight among the elderly with monthly individual income above a minimum wage 8 . However, another study with rural adults and elderly people in India found that those with medium and high socioeconomic status were more likely to be obese 25 . The divergence of the relationship between income and the occurrence of obesity in the elderly indicates the need to further analyze this situation through studies.…”

“…Regarding the marital status and housing scheme, it is important to mention that the lack of family support may favor nutritional problems 23 . However, the national 8,23 and international literature have not investigated this issue [24][25][26] . The identification of marital status and housing scheme is relevant, since, in rural areas, given the distance between locations and scarce social services, households eventually become the main source of resource and support 13 .…”

The prevalence of underweight, overweight and obesity in Bangladeshi adults: Data from a national survey

“…The prevalence of overweight and obesity that we report in urban Bangladesh (37%) is double the previous report of 17% based on a hospital (icddr,b) population of adults (≥20 years of age) in 2011 [18]. We found the prevalence of overweight and obesity in the rural areas (17%) was also higher than the 10% reported in rural women of reproductive age in 2000–2004 [19], but was less than half the prevalence reported in a rural community (aged ≥20 years) in 2009 which indicated that ~18% were overweight and 26% were obese[20]. In part, the discrepancy is due to different cut-points used to define overweight and obesity, as well as differences in the age of the population studied.…”

Cardiovascular Disease in Bangladesh: A Review

“…(Bangladesh Heart Journal 2016; 31 (2) : [80][81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99] The exact prevalence of CVD in Bangladesh is not known. Probably the first attempt to determine the prevalence of heart disease was made by Malik et al in a survey amongst 7062 people of different age groups in Dacca City and in a village; the surgery revealed the prevalence of 2.92%.…”
