Association between body mass index, demographics, and hypertension risk in South African university students.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundHigh blood pressure (BP) is becoming increasingly common among young adults, with university students representing a particularly vulnerable group, posing a growing public health challenge worldwide. The study explores the relationship between BMI and demographic characteristics related to elevated BP in this group, the study addresses a critical gap in local data and supports broader efforts to reduce the future burden of hypertension in South Africa.
objectivesThis study aimed to examine the association between BMI, demographic data, and elevated BP among university students in South Africa.
methodsA cross-sectional research study was conducted with university students. The researchers measured the participants' anthropometrics and BP and obtained their demographic data. Binary logistic regression was used to identify factors associated with elevated BP whilst descriptive statistics, t-tests and chi-square tests were used to profile the study's variables.
resultsThe prevalence of elevated BP was 46.4%. Elevated BP was more common among males (51.2%) and among students aged 25 years and older (58.9%). There was a significant association between BMI category and elevated BP, with students who were overweight showing an adjusted odds ratio (OR) of 1.98 (95% CI: 1.37-2.87), and students living with obesity showing an adjusted OR of 4.45 (95% CI: 2.73-7.27), compared to those with normal BMI. Additionally, pursuing a postgraduate degree and residing off campus were associated with increased odds of elevated BP. In contrast, being female was associated with lower odds of elevated BP (adjusted OR = 0.22, 95% CI: 0.16-0.31).
conclusionBMI, gender, educational level, and residence are significant predictors of high BP among university students. Early intervention is necessary to prevent hypertension in students.
