Malnutrition is a growing global health concern, affecting both developed and developing countries. While undernutrition and micronutrient deficiencies remain prevalent in many low-income regions, obesity is increasingly emerging as a significant problem, especially in urban areas. In developing countries, women of childbearing age are particularly vulnerable to malnutrition due to various biological, hormonal, and metabolic changes during this period. Pregnancy, being one of the most critical stages of life for both mother and child, places additional demands on the body, making proper nutrition even more vital. Adequate intake of essential nutrients—such as proteins, carbohydrates, fats, vitamins, and minerals—is crucial to maintaining health and preventing disease. Malnutrition during pregnancy can lead to serious health risks for both mothers and their infants, affecting fetal development, birth outcomes, and overall maternal well-being. This study aims to assess the knowledge of malnutrition among women of childbearing age in Rivers State, specifically in the context of the College of Health Science and Management Technology Demonstration Clinic, Port Harcourt. By evaluating the awareness and understanding of malnutrition in this group, the study seeks to identify gaps in nutritional knowledge that could contribute to poor health outcomes. Findings indicate a significant lack of awareness regarding essential nutrients and their impact on maternal and fetal health, emphasizing the need for improved education and interventions to combat malnutrition. This research underscores the importance of nutrition education and awareness for women of reproductive age as part of broader public health strategies to improve maternal and child health outcomes.
