Undernutrition and associated factors among rural pregnant women in Eastern Ethiopia.

Undernutrition was a significant public health issue among rural pregnant women. Age at first marriage, antenatal care follow-up, dietary diversity, current substance use, history of mental illness, and common mental disorder were the independent predictors of undernutrition. Therefore, the health offices of Kersa and Haramaya districts should invest their efforts to prevent undernutrition among pregnant women through nutrition counselling and education, and mental health and psychosocial support.
