Prevalence of undernutrition and its associated factors among pregnant women in north Shewa, Ethiopia: A multi-center cross-sectional study.

Background: Maternal undernutrition remains a public health issue, particularly in low-income countries such as Ethiopia, which increases the possibility of a cycle of malnutrition in future generations.

Objectives: This study assessed the prevalence of undernutrition and its associated factors among pregnant women in Minjar Shenkora district north Shewa, Ethiopia.

Design: The study used a multicenter cross-sectional study design.

Methods: The study was conducted from June to August 2021 with 334 pregnant women selected using systematic random sampling techniques. A semi-structured questionnaire was used to collect the sociodemographic, obstetric, and dietary data. The nutritional status of the pregnant women was assessed using mid-upper arm circumference measurements. Multivariate logistic regression was used to identify independent variables associated with maternal undernutrition, with an adjusted odds ratio (AOR) of p < 0.05 indicating statistical significance.

Results: The prevalence of undernutrition was 22.2%. Low monthly household average income (AOR = 3.69, 95% CI: 1.62-8.40), women's education limitation (AOR = 1.24, 95% CI: 0.28-5.46), poor nutritional attitude (AOR = 2.54, 95% CI: 1.21-5.32), and inadequate dietary diversity score (AOR = 4.42, 95% CI: 1.53-12.8) were significantly associated with undernutrition.

Conclusion: Maternal undernutrition prevalence was very high based on the WHO standards, and low monthly household average income, women's education level, poor nutritional attitude, and inadequate dietary diversity scores were associated with undernutrition. Therefore, policies and programs aimed at reducing maternal undernutrition are needed. Socioeconomic strengthening and nutritional counseling during pregnancy are also recommended for improved nutritional status.
