1.1 Introduction
Poor nutrition is one of the most significant public health challenges affecting children across the world, particularly in developing countries where poverty, food insecurity, and limited access to healthcare services remain common. According to the World Health Organization (2024), nutrition refers to the intake of food in relation to the body's dietary needs for proper growth, development, and maintenance of health. Good nutrition provides children with the essential nutrients required for physical growth, brain development, strong immunity, and overall well-being.
Children under the age of 15 years require adequate nutrition because this stage of life is characterized by rapid physical, mental, emotional, and cognitive development. According to the United Nations Children's Fund (2023), proper nutrition during childhood enhances learning ability, supports healthy growth, strengthens the immune system, and reduces the risk of illness and death. However, inadequate intake of balanced diets, poor infant and young child feeding practices, recurrent infections, and poor sanitation continue to expose many children to different forms of malnutrition, including undernutrition, micronutrient deficiencies, overweight, and obesity.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Historically, poor nutrition among children is closely linked to the evolution of public health, food production, and socioeconomic development across the world. According to the World Health Organization (2024), malnutrition has existed throughout human history and became more recognized as a major public health concern during the twentieth century when increasing evidence showed its relationship with childhood illness, poor growth, and mortality. Black et al. (2013) reported that global attention to child nutrition increased significantly after studies established that inadequate nutrition during childhood negatively affects physical growth, brain development, educational attainment, and economic productivity later in life.
Poor nutrition among children remains one of the most critical public health issues affecting both developed and developing countries. According to the WHO (2024), nutrition refers to the process by which the body obtains and utilizes nutrients from food to support growth, development, energy production, and the maintenance of good health. Good nutrition is particularly important during childhood because this stage is characterized by rapid physical, mental, emotional, and social development. Children under the age of 15 years require adequate intake of proteins, carbohydrates, fats, vitamins, minerals, and clean water to achieve healthy growth and prevent diseases. Poor nutrition occurs when the body fails to receive sufficient nutrients due to inadequate food intake, poor dietary quality, illness, or poor nutrient absorption. The consequences often include stunted growth, underweight, weakened immunity, delayed cognitive development, and poor educational outcomes.
United Nations Children's Fund (2023) reported that adequate nutrition during childhood improves learning ability, strengthens the immune system, supports healthy physical development, and reduces the risk of childhood illnesses. Similarly, Black et al. (2013) asserted that adequate nutrition during the early years of life contributes significantly to brain development, school readiness, and future economic productivity. Children who receive balanced diets are more likely to perform better academically, maintain healthier body weight, and develop stronger resistance to infectious diseases than those suffering from nutritional deficiencies.
In the same vein, Victora et al. (2021) reported that child malnutrition remains one of the leading causes of preventable illness and death among children worldwide. The researchers stated that millions of children continue to experience stunting, wasting, underweight, and micronutrient deficiencies despite various global nutrition improvement programmes. Likewise, the Food and Agriculture Organization of the United Nations (2023) affirmed that food insecurity remains a major contributor to poor nutrition among children, particularly in low- and middle-income countries. According to the organization, many households are unable to afford nutritious diets because of poverty, inflation, unemployment, climate-related food shortages, and rising food prices. Furthermore, the National Population Commission (Nigeria) and ICF (2024) reported that childhood malnutrition remains widespread in Nigeria despite various nutrition intervention programmes. This study is set against the backdrop of examining the causes and effects of poor nutrition among children under the age of 15 years in Ahiazu Mbaise Local Government Area, Imo State.
1.3 Statement of Problems
Investigation revealed that poor nutrition among children under the age of 15 years remains a major public health concern in many Nigerian communities, including Ahiazu Mbaise Local Government Area. Also, many children do not receive adequate quantities of balanced meals due to poverty, poor feeding practices, inadequate nutrition knowledge among caregivers, food insecurity, and limited access to quality healthcare services. As a result, many children experience stunted growth, underweight, weakened immunity, poor cognitive development, and increased susceptibility to common childhood illnesses (United Nations Children's Fund [UNICEF], 2023).
Additionally, inadequate awareness of appropriate child feeding practices, poor sanitation, frequent infections, and low household income have continued to worsen the nutritional status of children in many rural communities. Parents and caregivers often lack sufficient knowledge of age-appropriate diets, while some households depend mainly on carbohydrate-rich foods with little intake of proteins, fruits, and vegetables. These conditions contribute to poor physical growth, delayed mental development, reduced school performance, frequent hospital visits, and increased healthcare costs for families and communities (World Health Organization [WHO], 2024).
Furthermore, poor nutrition among children has wider social and economic consequences because unhealthy children are less likely to achieve their full educational and developmental potential, thereby affecting future productivity and community development. Although several studies have examined child nutrition in different parts of Nigeria, limited empirical attention has been given to the specific causes and effects of poor nutrition among children under the age of 15 years in Ahiazu Mbaise Local Government Area of Imo State. It is against this backdrop that this study seeks to examine the causes and effects of poor nutrition among children under the age of 15 years in Ahiazu Mbaise Local Government Area.

1.8 Scope of Study
This study focuses on the causes and effects of poor nutrition among children under the age of 15 years in Ahiazu Mbaise Local Government Area of Imo State, Nigeria. The study covers children under the age of 15 years, parents and caregivers, healthcare workers, and selected primary healthcare facilities under the Imo State Ministry of Health.
1.9 Limitations of the Study
During the course of this study, there were some problems encountered which stood as limitations to the research work. Some of the limitations include:
- Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
- Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet, questionnaire and interview).
- Initial Cooperation Delay from Respondents: A particular limitation of this work came as a result of the respondent refusal to offer their cooperation at the initial time they were contacted. This contributed in making the success of this research study difficult.
