The Prevalence of Micronutrient Deficiency in Early School-age Children

Study Overview
=================
Brief Summary
-----------------
This study aim to assess the prevalence of deficiency in micronutrients in early school-age children and its correlation with picky eating behavior, physical activity, nutritional status, and health status.

Detailed Description
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change serum concentrations of Hb (g/dL) may be found in children's serum | Change serum concentrations of Hb (g/dL) may be found in children with picky eating behavior, low quality of development, inadequacy of physical activity, undernutrition, and poor health status. | On the day of enrollment | 
| Change serum concentrations of ferritin (ng/ mL) may be found in children's serum | Change serum concentrations of ferritin (ng/ mL) may be found in children with picky eating behavior, low quality of development, inadequacy of physical activity, undernutrition, and poor health status. | On the day of enrollment | 
| Change serum concentrations of iron (μg/dL), zinc (μg/dL), and copper (μg/dL) may be found in children's serum | Change serum concentrations of iron (μg/dL), zinc (μg/dL), and copper (μg/dL) may be found in children with picky eating behavior, low quality of development, inadequacy of physical activity, undernutrition, and poor health status. | On the day of enrollment |
