Effect of community based health education on knowledge and attitude towards iron and folic acid supplementation among pregnant women in Kiambu County, Kenya: A quasi experimental study

Introduction Iron and Folic Acid Supplementation (IFAS) services are currently provided free of charge to pregnant women in Kenya during antenatal care (ANC) but compliance remains low. Poor awareness is an important factor contributing to low utilization of IFAS. Inadequate counselling is one of the key factors associated with poor awareness on IFAS. Community based health education is a promising diversification strategy for IFAS health education to curb this problem. Objectives To determine effect of community based IFAS health education, utilizing CHVs, on IFAS knowledge, levels of counselling on various IFAS topics and attitude towards IFAS among pregnant women in Kiambu County. Methodology A Pretest-Posttest Quasi-Experimental study design, consisting of intervention and control group, was applied among 340 pregnant women 18-49 years, in five health facilities, selected using two stage sampling in Lari Sub-County, Kiambu County, Kenya. Community health volunteers provided IFAS health education with weekly supplements and follow-ups to pregnant women in intervention group, while control group received the same from health care providers. Baseline and endline data were collected during ANC and compared. Quantitative data was analyzed using STATA version 14. Analysis of effect of intervention was done using Difference-In-Difference approach. Results There was an effect difference in maternal IFAS knowledge of 13%, with intervention group levels increasing most by 35 percentage points. The odds of being knowledgeable were 3 times more at endline than baseline. There was significant (p<0.001) change in proportion with positive attitude towards IFAS: the odds of having positive attitude at endline was 9 times that of baseline (OR = 9.2:95%CI 3.1, 27.2). Conclusion Implementation of community based health education improved maternal knowledge, positive attitude and proportion of pregnant women counselled on IFAS, better improvement being recorded in intervention group. Hence, there is need to integrate community based approach with antenatal IFAS distribution to improve supplementation.
