Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The Nutrition and Adolescence in Rural Nigeria (NARN'ia) study aims to address this gap through a comprehensive assessment of energy requirements in adolescent girls (N=50; ages 10 - 19 years) in Nigeria. NARN'ia will integrate dietary assessments using the 24-hour recall method (INDDEX24 app); physical activity levels using accelerometry; anthropometric evaluations of body composition, and the doubly labeled water method for assessing both body composition and total daily energy expenditure.
This study will provide evidence-based data essential for formulating appropriate nutritional guidelines for adolescent girls in Nigeria. Furthermore, this research initiative will establish a foundational framework for future studies on energy requirements in Nigeria and other low and middle-income countries.
