Evaluation of body mass index and basal metabolic rate, step number of days in boys children

Abstract

The study, evaluation was carried out to body mass index and basal metabolic rate, step number of days in boys children.

This study attended 588 boys child among aged 7-11 who are receiving education in Muğla Primary Schools in the education period of 2009-2010. Permission was taken from Muğla Provincial directorate for national education, schools directors and physical education teachers.

In order to determine the levels of step number of days with pedometer device 2 consecutive  week days and 1 weekend day to a total of three days measurements were made. In order to determine body mass index (BMI) formula (body weight / height ² ) were used. In order to determine rate of basal metabolism (BMR) formula (66.743+13.752 x Ağırlık (kg)+5.003*Boy (cm)-6.755 x Yaş (yıl)) were used.

Statistical analysis were made in the SPSS (version 15.0) packaged sortware.  Children’s body weight, height, BMI, physical activity level and basal metabolic rate (BMR) were compared with respect to the variable age. To determine differences occording to age one-way analysis (ANOVA), and  it was used Tukey HSD test  to determine which age group stems  differences in as a result of  anova.

Among children’s height, weight, physical activity levels, BMR and BKI values differences were found in the level of p<0,001. Among physical activity levels and age (r=-0,41), height (ı=-0,51), weight (r=-0,83), BMI (r=-0,89) and BMR (r=-0,83) levels of children negative relation was found in the level of p<0,001.

According to the findings in children have not seen  level of physical activity "very good". It was respected “good” level (10,00%), “medium” level (53,07%), “bad” level (28,91%) and “very poor” level (7,99%).

As a result, the average level of step number days of boys said that a moderate level. Physical activity levels in children is thought to remain limited because of factors such as Living conditions with the service to commute to school, an intensive exam preparation, private courses to go, to spend more time at the beginning of the computer and television.
