Maternal Knowledge, Attitudes, and Practices Towards the Prevention of Birth Defects in Eastern Cape, South Africa: A...

Background: Birth defects remain a major global public health concern, particularly in low-resource settings where awareness and preventive practices are limited. Maternal knowledge, attitudes, and practices (KAP) are critical in the prevention and management of birth defects. This study explored contextual factors influencing maternal KAP using a mixed-methods approach in three rural districts of the Eastern Cape, South Africa. Methods: A convergent mixed-methods cross-sectional study was conducted among 72 mothers selected through purposive sampling. Quantitative data were collected using a structured questionnaire administered in English only, covering socio-demographic characteristics, obstetric history, knowledge, and preventive practices. Qualitative data were obtained through interviews exploring beliefs, perceptions, and cultural explanations of birth defects. Quantitative data were analysed using descriptive statistics and linear regression analysis to identify factors associated with birth defects, while qualitative data were thematically analysed to provide contextual understanding. Results: Most participants resided in the Amathole district (63.89%), followed by Alfred Nzo (18.06%) and Joe Gqabi (18.06%). Most women were aged between 20 and 35 years (52.78%), while 15.28% were younger than 20 years and 6.94% were older than 45 years. Over half of the respondents were single (55.56%), 34.72% were married, and the remainder were either separated (4.17%) or divorced (5.56%). Numerous participants had primary education (56; 77.78%), followed by secondary (11; 15.28%) and tertiary education (5; 6.94%). The majority were unemployed (56; 77.78%), while smaller proportions were employed (10; 13.89%) or engaged in other income-generating activities (6; 8.33%), indicating limited participation in formal employment among respondents. Nearly all participants (95.83%) had experienced pregnancy, with 70.83% reporting pregnancy-related complications. Only 2.78% reported having a child with a birth defect, while 90.28% reported a family history of birth defects. Knowledge of genetic causes was relatively high (69.23%), but awareness of modifiable risk factors was limited. Although 93.06% recognized alcohol use during pregnancy as harmful, fewer participants identified smoking or medication use (18.06%) and advanced maternal age (26.39%) as risk factors. Only 13.89% acknowledged the preventive role of antenatal care. Qualitative findings revealed strong cultural influence on perceptions of birth defects, with causes attributed to medical factors (38.89%), supernatural beliefs such as witchcraft or curses (18.06%), immoral behaviour (12.50%), and dietary taboos (11.11%). Traditional health-seeking behaviour was common, with 91.67% consulting traditional healers during pregnancy. Linear regression analysis identified significant predictors of birth defects, including family history (β = 1.36, p = 0.008), alcohol use during pregnancy (β = 1.13, p = 0.050), and inadequate antenatal care attendance (β = 0.99, p = 0.040). Advanced maternal age showed a weaker and non-significant association (β = 0.79, p = 0.080). Conclusions: The study highlights substantial gaps in maternal knowledge and the strong influence of cultural beliefs on birth defect prevention. Strengthening culturally sensitive health education, improving antenatal care services, and engaging traditional healers in community-based interventions are essential to improve maternal health outcomes in rural South Africa.
