Abstract
Background: In persons 15 years and above in South Africa the prevalence of pre-diabetes and diabetes has been
estimated at 9.1% and 9.6%, respectively, and the prevalence of systolic prehypertension and hypertension, 38.2%
and 24.6%, respectively. Elevated blood glucose and elevated blood pressure are prototype of preventable chronic
cardiovascular disease risk factors.
Lifestyle interventions have been shown to control high normal blood pressure and/or high normal blood glucose.
Methods/Design: This study proposes to evaluate the efficacy of a community (church)-based lifestyle intervention
programme to control high normal blood pressure and/or high normal blood glucose in church members in a
randomized controlled trial in Gauteng, South Africa. The objectives are to: (1) measure non-communicable diseases
profile, including hypertension and diabetes, health behaviours, weight management and psychological distress of
church members; (2) measure the reduction of blood glucose and blood pressure levels after the intervention; (3)
prevent the development of impaired glucose tolerance; (4) compare health behaviours, weight management and
psychological distress, blood glucose and blood pressure levels between intervention and control groups, and
within group during 6, 12, 24 and 36 months during and post intervention. The study will use a group-randomized
design, recruiting 300 church members from 12 churches. Churches will be randomly assigned to experimental and
control conditions.
Discussion: Lifestyle interventions may prevent from the development of high blood pressure and/or diabetes. The
findings will impact public health and will enable the health ministry to formulate policy related to lifestyle
interventions to control blood pressure and glucose.
