The Prevalence of Micronutrient Deficiency in Early School-age Children

A structured questionnaire is used to conduct a cross-sectional descriptive study of 250 early school-age children aged 4-7 years (\<7 years old) in Taiwan. Data collection would include: demographics, food preferences, eating behavior, body weight and height, body mass index (BMI), physical activity, records of medical illness, peripheral cell blood count, serum values of ferritin and micronutrients (iron, zinc, copper). Data from children define as picky or non-picky eaters base on parental' questionnaire responses, are analyzed and compared using standard statistical tests. The correlations among eating behavior, dietary habits, development, physical activity, nutritional status, and health status, and micronutrient deficiency are evaluated.
