Abstract
AbstractHypertension is a chronic medical condition where blood pressure is too high. In Bangladesh, the overall incidence of hypertension is rising, like in other developing countries. Recent studies show hypertension can cause other non-communicable diseases such as cardiovascular diseases, strokes, etc. Utilizing information from the Bangladesh Demographic and Health Survey (BDHS) 2017–18, a cross-sectional and spatial analysis was done to determine the prevalence of hypertension. The existence of spatial autocorrelation is evaluated by using Moran’s I statistic, hotspot analysis, cold spot analysis, and influential observation analysis. The study was conducted on the basis of different factors such as gender, place of residence, age, BMI, etc. Among 12,926 people (43.19% men, 56.81% women), the women had a higher total prevalence of hypertension (41.18% (95% CI, 41.35–45.67) compared to the men’s 58.82% (95% CI, 57.16–60.45). Out of the total number of observations, 27.47% had hypertension. Out of all hypertensive people, 57.56% are unaware of their condition, which is very concerning. The study also finds that 28.4% are from urban areas and 71.6% are from rural areas. People living in the Dhaka division had a higher prevalence of hypertension (20.5%), and those in Sylhet had the lowest prevalence of hypertension (6.2%). There also exists a statistically relevant spatial autocorrelation (hypertension: Moran’s I index = 0.27, p<0.001). These are the spatial clustering maps, and according to the LISA cluster map, the Northeast districts are the cold spots (8), while the hotspots (4) are Bagerhat, Rajbari, Pirojpur, and Munshiganj. Approximately more than one-fourth of the adult population of Bangladesh had hypertension. The analysis discovered the hotspots and cold spots of the prevalence of hypertension. These findings could facilitate awareness and treatment of hypertension and therefore serve as support for researchers and policymakers.
