Obesity is known to impact negatively the functioning of the cardiovascular system. According to the Kenya
Ministry of Health Report (2012), up to 13.3% of males and 24% females are overweight and obese while 46.2% males and 42.7%
females have high blood pressure. The aim of this study was to determine the prevalence of obesity and the associated factors
among urban residents of Karen/Langata and Kibra Constituencies in Nairobi, Kenya.
This was a cross-sectional study based on a three-stage cluster sampling methodology across the socio-economic strata.
Assessments included measurement of weight and height, blood pressure (BP) check, fasting blood glucose, the lipid profile and
C-reactive protein concentrations. Information on demographics was also collected using a structured questionnaire. Data was
weighted and analyzed with values of p<0.05 considered statistically significant.
A total of 537 adults (m: 50.3%; w: 49.7%) aged 18 years and above participated in the study. The mean age was
38.09?13.4 years. The prevalence of obesity was 16.3% and higher in women than men (w: 27.3% vs. m: 5.9%). A significant
positive association (p<0.001) was observed between BMI and increasing age in both sexes. In men, obesity was significantly
associated with the lipid profile (p<0.001), higher socio-economic status (p<0.001), BP (p=0.004) and fasting blood glucose
concentration (p=0.003), whereas in women, BMI was strongly associated with CRP (p=0.002), the lipid profile (p<0.05) and BP
The gender disparity observed in the presentation of obesity and concomitant cormobidities calls for health
promotion and intervention efforts geared not only towards the observed cardiovascular risk factors but also the social cultural
and economic factors that may be responsible for the observed findings.
