A cross-sectional study on socio-demographic correlates of self-reported self-care practices for hypertension and type 2 diabetes among adults living in rural Kenya

Background: Hypertension and type 2 diabetes are among the most common non-communicable diseases that contribute to a large number of adult morbidity and mortality in Kenya. The impact of these conditions may pose great challenges in rural areas with limited access to healthcare services. The objective of the study was to assess socio-demographic factors associated with self-reported self-care practices for hypertension and type 2 diabetes among adults living in rural Kenya.

Methods: This study used data from the 2019 Baseline Assessment of the Prevention and Control of Non-Communicable Disease Project in Imenti South, Meru County conducted by the Kenyan Red Cross Society. A community-based study using a cross-sectional design was conducted among four hundred and thirty-five participants in Imenti South sub-County, Meru County in Kenya in November 2019. Chi-square test and logistic regression analyses were conducted to explore sociodemographic factors associated with self-reported self-care practices for hypertension and type 2 diabetes. Crude and Adjusted Odds Ratios with a 95% Confidence Interval (CI) were reported.

Results: Among the 435 participants, 37.0% self-reported hypertension, while 15.4% reported having type 2 diabetes. Variances in self-care practices were evident between the conditions, notably in terms of adequate fruit and vegetable intake and blood pressure screening. Among individuals with type 2 diabetes, 94% lacked sufficient fruit and vegetable consumption, contrasting with 98.7% among hypertensive participants (p = 0.042). Similarly, a significant majority of individuals with hypertension (71.4%) had blood pressure screening (p = 0.031). Multivariable logistic regression analysis revealed that individuals over 40 years exhibited higher odds of good self-care practice for hypertension compared to their younger counterparts (AOR: 4.67, 95% CI: 1.53-14.27, p = 0.007), whereas those residing in Mitunguu were 71% less likely to engage in such practices than those in Abogeta (AOR: 0.29, 95% CI: 0.09-0.90, p = 0.033). However, none of the variables demonstrated a significant association with self-reported self-care practices for type 2 diabetes following adjustment for potential confounding variables in the multivariable logistic regression analysis.

Conclusions: Our study identified socio-demographic factors, including age (> 40 years) and ward (Mitunguu), associated with self-reported self-care practices for hypertension among adults living in rural Kenya. However, we did not find significant associations between sociodemographic factors and self-care practices for type 2 diabetes. Furthermore, factors such as gender, education level, marital status, religion, employment status, and average monthly income did not show significant associations with self-care practices for hypertension or type 2 diabetes. These results provide insights regarding sociodemographic factors associated with self-care practices for hypertension among adults living in rural Kenya. Our study underscores the relevance of considering socio-demographic factors when making evidence-based policy decisions and designing intervention strategies tailored to the adult population in rural Kenya.
