Knowledge of risks of malaria in pregnancy on use of ITNs among pregnant women in northern Ghana

Abstract

Abstract Background Every year malaria in pregnancy causes 10,000 maternal mortalities worldwide, 20% of stillbirths, 11% of all new-born deaths and 900,000 low-birth-weight babies in sub-Saharan Africa. Maternal knowledge of malaria risks in pregnancy plays a significant role in malaria prevention. However, it is unknown if this preventable loss of lives and morbidities are caused by lack of knowledge, lack of prevention tools or both. We measured the pregnancy-related risks of malaria knowledge and bed net availability and use among pregnant women in Ghana. Methods We interviewed 770 pregnant women who attended antenatal care in 37 primary care clinics in Ghana from January through May 2019. We integrated this data in a sequential explanatory design with qualitative insights from 6 focus groups with 8 pregnant women each. Results 697/770 questionnaires were analyzed. 67% have general knowledge on malaria prevention but only 19% knew the specific risks on pregnancy outcomes. ITNs were owned by 89%, but only 75% reported to regularly use them. There was a statistically significant correlation between specific risks of malaria knowledge and ITN use (P<.001, OR = 2.0, CI:1.3-3.0). Other factors associated with ITN use were higher income, owning an ITN, higher parity, formal education, religion, and age. Reasons for non-adherence to ITN use include inappropriate hanging infrastructure, discomfort with using an ITN, and use of other prevention alternatives. Conclusions The study demonstrates that maternal knowledge on the risks of malaria in pregnancy significantly influenced their adherence to the use of insecticide-treated bed nets. Key messages The use of ITNs as a prevention method for malaria correlates to the knowledge of mothers about risks of malaria in pregnancy. Antenatal care malaria prevention efforts should focus more on teaching the specific risks of malaria in pregnancy.
