Objective: To examine whether women's knowledge of pregnancy-related risks and family support received during pregnancy are associated with adherence to maternal iron-folic acid (IFA) supplementation.
Design: Secondary data analysis of the 2002-03, 2007 and 2012 Indonesia Demographic and Health Survey. Analysis of the association between factors associated with adherence (consuming ≥90 IFA tablets), including the women's knowledge and family support, was performed using multivariate logistic regression.
Setting: National household survey.
Subjects: Women (n 19 133) who had given birth within 2 years prior to the interview date.
Results: Knowledge of pregnancy-related risks was associated with increased adherence to IFA supplementation (adjusted OR=1·8; 95 % CI 1·6, 2·0), as was full family (particularly husband's) support (adjusted OR=1·9; 95 % CI 1·6, 2·3). Adequate antenatal care (ANC) visits (i.e. four or more) was associated with increased adherence (adjusted OR=2·2; 95 % CI 2·0, 2·4). However, ANC providers missed opportunities to distribute tablets and information, as among women with adequate ANC visits, 15 % reported never having received/bought any IFA tablets and 30 % had no knowledge of pregnancy-related risks. A significant interaction was observed between family support and the women's educational level in predicting adherence. Family support significantly increased the adherence among women with <9 years of education.
Conclusions: Improving women's knowledge of pregnancy-related risks and involving family members, particularly the husband and importantly for less-educated women, improved adherence to IFA supplementation. ANC visit opportunities must be optimized to provide women with sufficient numbers of IFA tablets along with health information (especially on pregnancy-related risks) and partner support counselling.
