Physical activity levels and its associated factors among adults in Vihiga county, Kenya.

Sedentary lifestyle is a major risk factor for cardiovascular diseases (CVDs) which account for 8% of Kenya's non-communicable disease (NCD) burden. Prevalence of physical inactivity remains high globally. There is paucity of data on physical activity levels in rural Sub-Saharan Africa to inform effective interventions. This study sought to establish levels and factors associated with physical activity in a rural population in Kenya. This was a cross-sectional study in Vihiga, a predominantly rural County in Kenya. Participants were adults aged ≥18 years drawn from four community markets. Stratified sampling by ecological zones and rural/urban status was used to select the four markets and Sampling the Next Customer Exiting the Market method for the respondents. Researcher administered e-questionnaire adapted from International Physical Activity Questionnaire (IPAQ) was used to collect data. Physical activity was calculated as the sum of all Metabolic Equivalents (MET)-minutes/week. Multivariable binary logistic regression analysis was used to identify correlates of physical activity. Out of the total 375 (m: 49%; f: 51%) participants, 27% were physically inactive (m: 22%; f: 32%;) and 42% engaged in low level physical activity. Majority of the respondents (75.5%) engaged in transportation-related physical activity while 32% engaged in leisure physical activities. The odds of being physically inactive were 1.93 times higher for females, 2.62 higher for those aged ≥65 years, and 3.62 higher for those with high health literacy. 48% with high health literacy were in the early working age group (15-24 years). Majority (53%) received health information from healthcare workers, especially for the 60% physically inactive participants. This study highlights the need for targeted community interventions to address the observed physical inactivity especially among women and older adults in rural Kenya.
