NCT ID NCT04056377
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at over 1,000 South African children ages 5 to 9 to understand why some develop early signs of high blood pressure and heart problems. Researchers will measure blood pressure, body fat, and fitness, and test blood for early warning markers. The goal is to find ways to prevent heart disease later in life.

Who is studied
The study population included 1103 children (at baseline) attending public primary schools in the Dr Kenneth Kaunda district, North West province, South Africa aged between 5 and 9 years of age. However, with a few missing (n=38) values of basic variables of interest such as sex, ethnicity or date of birth, we included a total 1065 children (mean age=7.44 years or 89.3 months). The majority of the participants were of African (n=579) and white (n=463) ethnicity, whereas only 2.2% (n=23) participants were of either Indian or mixed race. The sex distribution was similar in the white group, whereas the study unintentionally included more girls (58.5%) than boys (41.5%) in the black group.
