Abstract:The study investigated dietary intake knowledge and reasons for food restriction during pregnancy among pregnant women attending antenatal clinics in Ile-Ife, Nigeria. This cross-sectional survey involved 530 pregnant women visiting 35 primary health care (PHC) centers in Ile-Ife. Interviewer-administered questionnaire used to collect data included a 30-point knowledge scale and food restriction related questions. Data were analyzed using descriptive statistics and chi-square at P = 0.05. Mean age was 27.0 ± 5.3 years, 44.5% had tertiary education and 11.1% earned above ₦50,000 monthly (approximately US$315). Mean knowledge score was 23.6 ± 4.2 and 75.5% had good knowledge. Higher education was significantly associated with good knowledge of dietary intake. Reasons for food restriction during pregnancy included cultural taboos (36.5%) and religious beliefs (12.1%). Major foods that were restricted or avoided for cultural reasons were protein and vitamin-rich foods such as snail (97.5%) and walnut (84.0%). Foods avoided based on religious beliefs included pork (87.4%) and dog (76.9%). A higher proportion (94.8%) of respondents who earn more than ₦50,000 avoided foods due to cultural taboos (94.8%) compared with those without monthly income (58.3%) (P≤0.05). The proportions of respondents who avoided foods due to cultural taboos with no formal, primary, secondary, and tertiary education were 95.5%, 93.8%, 79.8%, and 86.4% respectively (P≤0.05). Overall, respondents were knowledgeable about dietary intake. However, cultural taboos and religious beliefs were major reasons for food restriction among pregnant women and were more pronounced among women with low education and low monthly income. Nutrition education interventions are needed to address the phenomenon. Keywords: pregnant women, food restriction, dietary intake, cultural taboos
