60 Minutes Per Day in Moderate to Vigorous Physical Activity as a Natural Health Protector in Young Population.

The aim of this study was to check whether following the recommendations of the World Health Organization (WHO) concerning physical activity protects children and adolescents against the occurrence of overweight and obesity. A total of 1002 children were included in the analysis. The average age of the studied children was 9.36 years ± 3.52 years. Measurement of height and body mass was performed for every child, followed by physical activity assessment over seven days. In each group analyzed, the overweight and obese children had a shorter time in moderate to vigorous physical activity (MVPA) than the children with normal body mass. Among the children spending < 60 min per day in MVPA, the risk of occurrence of overweight and obesity was greater than among children with physical activity > 60 min per day. It was also shown that the greatest risk of occurrence of body mass disorder was a situation in which the mother's gestational weight gain (GWG) is over 18 kg and the child does not spend a minimum of 60 min/day in MVPA. Not meeting the recommendation is connected with an increased chance of the occurrence of overweight and obesity. The level of physical activity influences the incidence of overweight and obesity. The children with overweight and obesity spent less time per day in MVPA. An increased body mass in mothers during pregnancy associated with a child's low level of physical activity increases the risk of the occurrence of overweight and obesity.
