Risk factors for chronic non communicable diseases in Mombasa, Kenya: epidemiological study using WHO stepwise approach

OBJECTIVE: To describe the prevalence and distribution patterns of the major common risk factors for non communicable diseases among the people living in Mombasa, Kenya. METHODS: Using the WHO STEPwise approach, risk factors for non communicable diseases were analyzed for 305 people aged between 13 to 67 years. The study sample was arrived at through convenient stratification of the population according to age and setting followed by random selection of the participants. RESULTS: The most common individual risk factors registered were physical inactivity, hypertension and overweight/obesity accounting for 42%, 24% and 11% of the sample respectively. Participants who possessed a single risk factor profile were 42% and those who had multiple risk factors were approximately 17%. Hypertension and physical inactivity were the most common multiple risk factor pattern possessed by 7.5% of the participants who had at least one of the investigated risk factors for CNCDs. Socio-demographic characteristics including male gender, increasing age, being a student and low socio-economic status were found to be positive predictors of CNCDs CONCLUSION: The burden of CNCDs risk factors is unequally distributed among Mombasa residents. The poorest quintile posses the worst risk factor profile compared to their privileged counterparts. The implementation of WHO STEPwise approach was feasible since it revealed a comprehensive picture of the at-risk groups thus forming a vital baseline framework for target specific and cost-effective CNCDs control and prevention interventions.Web of Scienc
