Hypertension has been rapidly growing in Bangladesh. However, there has been limited analysis of differences in the hypertension cascade across socio-demographic groups. This study was a secondary analysis of the 2017–18 Bangladesh Demographic and Health Survey. Four dichotomous outcome variables – hypertension prevalence, awareness among those with hypertension, treatment among those aware, and control among those treated – were analyzed. The variation of each outcome was assessed across socio-demographic factors. The association between socio-demographic characteristics and outcomes was analyzed using logistic regression. Less than half of the hypertensive individuals were aware of their hypertension (42.5%), and awareness was higher among those who were older, female, of higher household wealth, and living in urban areas. Among those aware, most were receiving treatment (87.4%), and this proportion was higher in older individuals (89.2% among 65 + , 70.4% among 18–24; p < 0.001). One-third of those treated (33.8%) had their blood pressure controlled, and this was higher among younger and more educated individuals. In multivariable models stratified by rural/urban community, most of the aforementioned trends remained with additional differences between communities. Notably, the association of higher education level with treatment odds differed in rural and urban communities (OR 0.34 [95%CI 0.16, 0.75] in rural; OR 2.83 [95%CI 1.04, 7.73] in urban). Efforts to improve hypertension awareness among individuals who are younger, male, of lower household wealth, and in rural areas are required to address disparities in care. Socio-demographic variations in hypertension awareness, treatment, and control must be considered to design targeted interventions for each step of the cascade.
