Applying a knowledge-to-action framework for primary prevention of spina bifida in tropical Africa.

Maternal periconceptual folate supplementation reduces the incidence of neural tube defects; however, in settings where population-level food fortification is not available, it is not clear how best to promote this prevention strategy. Guided by a knowledge-to-action methodology, we used mixed quantitative and qualitative methods to define the local disease burden, then designed, implemented and evaluated a culturally tailored educational intervention in eastern Democratic Republic of Congo, where resource limitations and threats to human security contribute to restricted capacity for the prevention and management of congenital malformations. A descriptive case series of 27 patients undergoing surgery for spina bifida demonstrated a short-term mortality of 15% and long-term disability in survivors. A survey of knowledge, attitudes and practices demonstrated a low level of folate awareness (53%) among women of reproductive age. Focus group discussions revealed exotic aetiologic views, significant gender issues and several barriers to folate use. A culturally tailored radio broadcast and an educational video were designed and produced locally based on qualitative and quantitative findings. Evaluation of the video documented high levels of viewer satisfaction and unequivocal knowledge gain (P ≤ 0.001). We conclude that spina bifida poses a significant burden on affected patients and their families in the African context, but folate is underutilized as a prevention strategy. Patient education through video media results in increased awareness and understanding of spina bifida and folate, a first step in empowering women to reduce the risk of spina bifida in their children in the absence of population-wide food fortification.
