We observed a lower level of physical activity among rural than

urban students. This finding was unexpected, most likely explained

by the fact that rural students were in a boarding school therefore

had minimal travelling distance to their classes.

45

There are some limitations. The study had a small sample size

and relied on some self-reported variables that were prone to recall

bias. We measured blood pressure on only two visits. More than

two readings would have been needed to provide the best estimate

of blood pressure.

Conclusion

This study has shown that hypertension, overweight/obesity and

alcohol intake were common among these senior secondary school

students in Botswana. Strategies to prevent the risk factors of

CVD should be developed and implemented to avoid CVD-related

morbidity and mortality in the future. These strategies are being

advanced and will be the subject of future research.
