Abstract

Background: Childhood hypertension drives hypertension in later life; hence, assessing blood pressure in children is an important measure to determine current and future cardiovascular health. There is, however, a paucity of childhood blood pressure data, particularly for sub-Saharan Africa. Purpose: This study explores blood pressure and associations with age, sex, socioeconomic status, physical activity, fitness, and cardiovascular risk markers. Methods: In the ‘Disease, Activity and Schoolchildren’s Health’ (DASH) study, a cross-sectional analysis was conducted in disadvantaged neighbourhoods in the Eastern Cape province of South Africa. Assessments included blood pressure, accelerometer-measured physical activity, physical fitness, and cardiovascular risk markers. Results: The study consisted of 785 children (383 boys, 402 girls, M = 12.4±0.9 years). Overall, 18% of the children were classified as hypertensive, while 20% were either overweight/obese, and almost four out of ten children did not meet global daily physical activity recommendations. Hypertensive children were more likely to be overweight/obese, χ2 (2,785) = 14.42, p < 0.01, but only if they did not meet physical activity recommendations, χ2 (2,295) = 11.93, p < 0.01 (Figure 1). Conclusion: Considering the moderating effect which sufficient activity has on the relationship between hypertension and body weight, more emphasis should be placed on holistic early primary health intervention and education strategies. Funding: This work was conducted within the scope of the Swiss-South African Joint Research Programme, jointly funded by the Swiss National Science Foundation and the National Research Foundation of South Africa. The cross-sectional study was further supported by the Novartis Foundation (Basel, Switzerland).
