Differences In Cardiovascular Disease, Biochemical Risk Markers, Physical Activity And Nutrition Between An Urban And Pastoral Sample In Kenya

ABSTRACT

The purpose of this study was to determine the differences in blood pressure,

cardiovascular disease bio-chemical risk markers, physical activity and nutrition,

between an Urban (US) and Pastoral (PS) sample, in the context of the global

epidemiological transition taking place globally causing a shift in mortality and

morbidity from communicable diseases to non-communicable diseases. A total of 133

adults from both samples meeting the inclusion criteria, were randomly recruited from

clusters in sub-locations, villages and homesteads from available demographic data

available from Central Bureau of Statistics (CBS) on Kirisia and Kibera divisions in

Samburu and Nairobi, in Kenya. Data was collected using questionnaires, venipuncture,

blood pressure measurement and anthropometric measurements. Resulting data was

stratified and analyzed by locality, gender and age-category using SPSS V 11.5 and

computed in terms of percentages and frequencies. Chi-square test was used to test for

differences in proportions. Student t-test and ANOVA were used to compare means

where applicable and in cases where there were more than two means being compared.

The level of significance at 0.05 was used for the statistical tests. In case of significant

F-ratio, post-hoc analysis was done using DMRT. Stepwise multiple regression analysis

was used to identify predictors of cardiovascular disease, p-values
