Prevalence and risk factors of hypertension in rural Bangladesh: A population-based cross-sectional study.

TL;DR

A population-based cross-sectional study in rural Bangladesh found that 33.7% of men and 28.6% of women had elevated blood pressure, with age, gender, and socioeconomic status identified as significant predictors of hypertension, and age and overweight/obesity as the strongest risk factors in both genders.

Key Findings

A substantial proportion of rural Bangladeshi adults had elevated blood pressure qualifying them as prehypertensive or hypertensive.

  • 33.7% of men had elevated blood pressure
  • 28.6% of women had elevated blood pressure
  • The study surveyed adults aged ≥18 years from 7,384 households across 149 villages in rural Bangladesh in 2017
  • Participants were household heads and their spouses

Age, gender, and socioeconomic status were identified as significant predictors of hypertension in multivariate logistic regression analyses.

  • Multivariate logistic regression analyses were used to identify predictors
  • Age and overweight/obesity were found to be the strongest risk factors for hypertension in both genders
  • Education was not found to be significantly associated with hypertension in women
  • Data were collected using a semi-structured questionnaire covering blood pressure, anthropometric, socioeconomic, lifestyle, and behavioral risk factors

Overweight and obesity rates were higher among individuals from higher socioeconomic status groups in both men and women.

  • Overweight prevalence was 4.29% and obesity 1.4% in adult men from higher SES groups
  • Overweight prevalence was 5.8% and obesity 2.29% in adult women from higher SES groups
  • Overweight and obesity are identified as risk factors for the development of hypertension

Higher socioeconomic status was associated with greater fruit and vegetable consumption in both men and women.

  • Fruit consumption was 10.29% and vegetable consumption 7.25% in adult men from higher SES groups
  • Fruit consumption was 9.95% and vegetable consumption 6.84% in adult women from higher SES groups
  • These findings suggest a complex relationship between SES, diet, and hypertension risk

A significant association between tobacco consumption and age was observed in women.

  • The association between tobacco consumption and age was statistically significant for women (p<0.0001)
  • No equivalent statistically significant association was reported for men in the abstract
  • Tobacco consumption was among the behavioral risk factors assessed via the semi-structured questionnaire

Physical activity levels varied by age and socioeconomic status, with notable gender differences.

  • Higher levels of physical activity were found among men aged 45-54 years [OR: 1.9, CI 95% (1.1-3.1)]
  • Women in the highest SES brackets were 1.3 times as likely to engage in 'moderate' physical activity as those in the lowest brackets
  • Physical activity was among the lifestyle factors assessed in the study

This study addresses a gap in population-based research on hypertension in rural Bangladesh.

  • The study was a population-based cross-sectional design conducted in 2017
  • Data were collected from 7,384 households across 149 villages
  • The authors note the lack of prior population-based studies in rural Bangladesh as a key motivation
  • The study population targeted adults aged ≥18 years, specifically household heads and their spouses

What This Means

This research surveyed over 7,000 rural households across 149 villages in Bangladesh to understand how common high blood pressure is and what factors contribute to it. The study found that roughly one in three men (33.7%) and more than one in four women (28.6%) had blood pressure levels high enough to classify them as prehypertensive or hypertensive — a significant public health concern. Getting older and being overweight or obese were the strongest predictors of high blood pressure for both men and women. The study also revealed important connections between socioeconomic status (SES), lifestyle, and hypertension risk. People with higher incomes were more likely to be overweight or obese, but also more likely to eat fruits and vegetables. Women with higher SES were more likely to engage in moderate physical activity, while older men (ages 45-54) were generally more physically active. Among women, tobacco use was strongly linked to age. Interestingly, education level was not significantly associated with hypertension risk in women, suggesting that simply improving educational attainment may not be sufficient to reduce hypertension rates among rural Bangladeshi women. This research suggests that efforts to reduce hypertension in rural Bangladesh need to account for gender-specific risk factors, differences between rural and urban populations, and the role of socioeconomic context. A one-size-fits-all approach is unlikely to be effective. Policy interventions should specifically target the risks associated with increasing overweight and obesity rates, particularly as economic conditions change in rural communities, and should consider tailored approaches for men and women separately.
