Determination of Reference Values for Handgrip Strength and Bioimpedance Values in Healthy Turkish Children

Study Overview
=================
Brief Summary
-----------------
In this study, our aim is to determine the reference values for the handgrip force and bioimpedance values in healthy Turkish children.

Detailed Description
-----------------
In this study, our aim is to determine the reference values for the handgrip force and bioimpedance values in healthy Turkish children. The study was planned as a cross-sectional clinical study. All healthy children studying at Hamdi Akverdi Primary School and Halil Bedii Management Secondary School in the Bakırköy region of Istanbul will be included. The date of birth of the children will be learned. It will be determined in which city in Turkey the population is registered. TANITA BIA analysis and hand grip strength (with jamar) measured in the dominant hand were planned for all children. In addition, the calf circumference of all children will be measured. Written consent forms will be obtained from the families of the children before the evaluation. It was planned to include 1500 children in the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| handgrip strength | Handgrip strength will be measured using a Jamar hand grip dynamometer (Model 5030J1, Sammons Preston Rolyan, Bolingbrook, Illinois, USA). Measurements will be taken 3 times in a sitting position with the elbow flexed to 90° and the wrist in neutral position. The measured maximal grip strength will be recorded as hand grip strength. | 1 interview day | 
| calf circumference | Calf circumference is an anthropometric measurement that indicates fatfree muscle mass and has been considered by the World Health Organization (WHO) the most sensitive index for evaluating the decrease in muscle mass. Calf circumference will be measured with an elastic band over the subject's right leg, both sitting and standing. | 1 interview day | 
| Body Mass Index (BMI) | BMI will be calculated as weight (kg) divided by height2 (m2) | 1 interview day | 
| Skeletal muscle mass | Skeletal muscle mass will be evaluated using a Tanita DC-360 multi-frequency body composition analysis device. | 1 interview day |
