Prevalence and determinants of hypertension among adults of reproductive age in Tanzania: analysis of a cross-sectional Demographic and Health Survey.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe aimed to estimate prevalence and identify determinants of hypertension in adults aged 15-49 years in Tanzania.
designWe analysed cross-sectional survey data from the 2022 Tanzania Demographic and Health Survey and Malaria Indicator Survey conducted between February and July 2022. Descriptive statistical analysis, logistic regression, machine learning and geospatial methods were used to estimate prevalence and determine determinants of hypertension.
settingTanzania.
participantsA total of 13 385 participants aged 15-49 years were included in the analysis. PRIMARY OUTCOME: The primary outcome variable was hypertension, defined as either systolic blood pressure (BP)≥140 and/or diastolic BP≥90 mm Hg or under anti-hypertensive drugs.
resultsThe prevalence of hypertension among adults of reproductive age was 11% (95% CIs 10.09 to 11.56) in Tanzania, varying significantly across risk factors. Prevalence was high in people aged 40-49 (22.11%, 95% CI 20.07 to 24.29) and obese (23.69%, 95% CI 20.67 to 27.00). The mean prevalence of hypertension was also high in the southern, eastern, western, southern highlands, north-west and north-eastern part of the country, correlating with the spatial distribution of older age (30-49) and higher body mass index (BMI) (≥25). Individuals aged 40-49 had nearly six times (adjusted OR (AOR): 5.68, 95% CI 4.10 to 7.83) the odds of hypertension relative to those aged 15-19. Obese individuals had higher odds (AOR: 2.88, 95% CI 2.01 to 4.13) compared with overweight individuals (AOR: 1.93, 95% CI 1.36 to 2.74). Machine learning results showed age and BMI as the most important determinants of hypertension and that significant interactions between risk factors exist.
conclusionThe prevalence of hypertension varied across risk factors and the strongest determinants of hypertension in adults of reproductive age were age and BMI.
