Assessing knowledge of hypertension and diabetes mellitus among informal healthcare providers in urban slums in southeastern Nigeria

Informal healthcare providers (IHPs) often serve as the first point of contact for healthcare services for non-communicable diseases in urban slums and their ability to identify risk factors and symptoms of the diseases is crucial for early detection and management. This paper assesses level of knowledge of hypertension and diabetes mellitus (DM) among IHPs. A cross-sectional survey was conducted in eight slums in Enugu and Onitsha cities in south-eastern Nigeria. Data was collected from 238 IHPs including patent medicine vendors, traditional birth attendants, traditional bonesetters, and herbalists. Knowledge scores were computed for each respondent. Adequate knowledge was set at ≥ 50% score and inadequate knowledge at < 50%. Binary logistic regression analysis was used to identify factors/independent variables associated with adequate knowledge among IHPs. Independent variables in the regression model were seven items that describe the profile of IHPs and can influence their access to information on non-communicable diseases. Knowledge of risk factors and symptoms of hypertension and DM among IHPs was low since only 21 (8.82%) and 19 (7.98%) of them had adequate knowledge of hypertension and DM, respectively. In regression analysis, IHPs who had received formal training in the past demonstrated significantly higher levels of knowledge, with odds of adequate knowledge in hypertension being 14.62 times greater for trained providers, and the odds of adequate knowledge of both non-communicable diseases being 21.34 times greater for trained providers. Training of IHPs is needed to address the critical knowledge deficit of risk factors and symptoms of hypertension and DM. This would contribute to better health outcomes and reduced disease burden in urban slums.
