1.0 Introduction
1.1 Background of Study
In recent decades, research has increasingly focused on the long-term impact of early nutrition on health outcomes. The concept of the "first 1,000 days", from conception to a child's second birthday, has gained prominence, emphasizing the critical window for nutritional interventions. Contemporary studies continue to explore the links between pediatric nutrition and chronic diseases, cognitive development, and overall well-being, highlighting the need for evidence-based dietary recommendations and public health policies (Black et al., 2013). The 20th century brought major advancements in the understanding of pediatric nutrition. The discovery of vitamins and the identification of essential nutrients highlighted the importance of a balanced diet for growth and development. World War II underscored the need for adequate nutrition, leading to the establishment of national nutrition programs and guidelines (Truswell, 2003).
The foundation of human health is significantly influenced by nutrition during the early stages of life. From infancy through adolescence, proper nutrition is essential for supporting rapid growth, cognitive development, and overall physical health. The interplay between nutrition and health during these formative years can have long-lasting effects, shaping an individual's health trajectory into adulthood.
Infancy is characterized by rapid growth and brain development. The World Health Organization (WHO) emphasizes the importance of exclusive breastfeeding for the first six months of life, as breast milk provides all the necessary nutrients in the correct proportions, supports the immune system, and fosters a strong mother-child bond (WHO, 2002). Despite the well-documented benefits of breastfeeding, global adherence to recommended breastfeeding practices remains suboptimal due to various socio-economic, cultural, and individual barriers (Victora et al., 2016).
Adolescence is marked by significant physiological and psychological changes, requiring increased nutritional support. Adequate intake of calcium, iron, and protein is particularly important during this stage to support bone growth, muscle development, and overall physical health. Poor dietary habits established during adolescence can lead to long-term health consequences, such as obesity, and cardiovascular diseases (Story, Neumark-Sztainer, & French, 2002). Pediatric nutrition is a critical aspect of health that significantly influences the growth, development, and overall well-being of infants, children, and adolescents. Proper nutrition during these formative years is essential for cognitive development, physical growth, and the establishment of lifelong healthy eating habits. Inadequate or improper nutrition can lead to a range of health issues, including obesity, developmental delays, and increased susceptibility to illnesses.
During infancy, nutrition is pivotal as it supports rapid growth and brain development. Breastfeeding is highly recommended due to its comprehensive nutritional profile and immune-boosting properties. According to the American Academy of Pediatrics, exclusive breastfeeding for the first six months of life provides ideal nutrition and supports optimal growth and development (American Academy of Pediatrics, 2012). As children grow, their nutritional needs evolve. A balanced diet rich in essential vitamins and minerals is crucial for maintaining energy levels, supporting immune function, and promoting healthy bone and muscle development. Nutritional deficiencies during childhood can result in chronic health problems and impact academic performance (Black et al., 2013).
The transition from infancy to childhood involves significant dietary changes as children begin to consume a more varied diet. This period is critical for establishing healthy eating patterns that can prevent malnutrition and obesity. Adequate intake of essential nutrients such as iron, calcium, vitamins, and protein is vital for sustaining energy levels, supporting immune function, and promoting healthy growth (Hurley, Cross, & Hughes, 2011). However, many children worldwide suffer from micronutrient deficiencies and poor dietary habits, which can hinder their development and academic performance (Prado & Dewey, 2014).
Adolescence is marked by profound physical, emotional, and social changes that increase nutritional requirements. The rapid growth spurts and hormonal changes necessitate higher intakes of calories, proteins, and essential nutrients such as iron and calcium (Spear, 2002). Adolescents are particularly susceptible to developing unhealthy eating behaviors, such as skipping meals, consuming fast food, and engaging in dieting practices that can lead to eating disorders and other health issues (Neumark-Sztainer et al., 2010). The long-term impact of nutrition during childhood and adolescence on adult health cannot be overstated. Proper nutrition is associated with a lower risk of chronic diseases such as obesity, and certain cancers (Barker, 2004). Conversely, poor nutrition can lead to a range of adverse outcomes, including stunted growth, cognitive impairments, and increased morbidity and mortality (Bhutta et al., 2013). Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the pediatric nutrition impact on infant child and adolescent health.
1.2 Statement of Problems
Investigation revealed that overnutrition and the rising rates of childhood obesity present a significant public health challenge, especially in high-income and urbanizing regions. Obesity in childhood and adolescence is associated with a higher risk of developing non-communicable diseases such as type 2 diabetes, and certain cancers later in life. The increasing consumption of energy-dense, nutrient-poor foods, along with sedentary lifestyles, contributes to this epidemic (Ng et al., 2014). A major barrier to improving pediatric nutrition is the lack of access to affordable, nutritious foods. Food insecurity, driven by economic disparities and environmental factors, limits the ability of families to provide balanced diets for their children. This is exacerbated by inadequate public health policies and programs that fail to address the root causes of nutritional deficiencies and obesity (Hoddinott et al., 2013).
Moreover, cultural practices and misconceptions about nutrition often hinder the adoption of healthy feeding practices. In many communities, traditional beliefs about infant feeding and weaning can conflict with scientifically recommended practices, leading to suboptimal nutritional outcomes (Bentley et al., 2014).
Additionally, there is a critical gap in knowledge and awareness among parents and caregivers regarding the importance of early nutrition. Many caregivers lack the information and support needed to make informed decisions about feeding practices, which can result in poor dietary choices that negatively impact a child's health and development (Victora et al., 2016).
The persistent issues of undernutrition, overnutrition, food insecurity, cultural barriers, and lack of awareness highlight the urgent need for comprehensive strategies to improve pediatric nutrition. Addressing these problems requires coordinated efforts that involve public health interventions, education, policy reforms, and community engagement to ensure that all children have the opportunity to achieve optimal health and development through proper nutrition.

1.9 Definition of Terms
Pediatric Nutrition:
Pediatric nutrition refers to the dietary requirements of infants, children, and adolescents to ensure their proper growth, development, and health. It encompasses breastfeeding, formula feeding, introduction of solid foods, and balanced diets rich in essential nutrients (Mahan, Escott-Stump, & Raymond, 2012).
Infant Nutrition:
This term refers to the nutritional practices and needs of infants from birth to one year of age. It includes breastfeeding, formula feeding, and the gradual introduction of complementary foods. Proper infant nutrition is critical for healthy growth and immune system development (World Health Organization, 2003).
Child Nutrition:
Child nutrition involves the dietary needs and practices for children aged one to twelve years. This period includes the transition from infancy to more varied diets and the establishment of eating habits that support ongoing physical and cognitive development (National Academies of Sciences, Engineering, and Medicine, 2019).
Adolescent Nutrition:
Adolescent nutrition pertains to the dietary requirements of individuals aged 13 to 19 years. This phase involves significant physical growth, hormonal changes, and increased nutritional needs. Proper nutrition during adolescence supports overall health and helps prevent chronic diseases (Story, Neumark-Sztainer, & French, 2002).
Malnutrition:
Malnutrition refers to deficiencies, excesses, or imbalances in a person’s intake of energy and/or nutrients. It encompasses both undernutrition (stunting, wasting, and micronutrient deficiencies) and overnutrition (overweight and obesity) (World Health Organization, 2020).
Stunting:
Stunting is impaired growth and development that children experience from poor nutrition, repeated infection, and inadequate psychosocial stimulation. It is measured as a height-for-age ratio more than two standard deviations below the World Health Organization Child Growth Standards median (De Onis et al., 2006).
Wasting:
Wasting is a form of acute malnutrition characterized by a significant loss of weight relative to height. It indicates a recent and severe process of weight loss, often due to starvation or severe disease (World Health Organization, 2020).
Micronutrient Deficiencies:
These deficiencies, also known as "hidden hunger," occur when people do not get enough essential vitamins and minerals, such as iron, vitamin A, and iodine, in their diet. Micronutrient deficiencies can lead to serious health problems, especially in children (World Health Organization, 2020).
Food Insecurity:
Food insecurity is the state of being without reliable access to a sufficient quantity of affordable, nutritious food. It can negatively impact health, development, and well-being, particularly in children (Coleman-Jensen et al., 2019).
Breastfeeding:
Breastfeeding is the act of feeding a baby with milk directly from the mother's breast. It is recommended as the optimal source of nutrition for infants, providing essential nutrients and antibodies that support early development and immune function (American Academy of Pediatrics, 2012).
Complementary Feeding:
Complementary feeding is the process of introducing solid and semi-solid foods to an infant’s diet alongside breast milk or formula, typically starting around six months of age. This practice is crucial for providing additional nutrients needed for continued growth and development (World Health Organization, 2003).
Chronic Diseases:
Chronic diseases are long-lasting conditions that usually can be controlled but not cured. They include heart disease, diabetes, and obesity, and can be influenced by nutrition and lifestyle factors starting from a young age (Centers for Disease Control and Prevention, 2020).
