Physical activity interventions were consistently ( > 60 % of studies ) associated with improved motor and cognitive development , and psychosocial and cardiometabolic health .
Across observational studies , physical activity was consistently associated with favourable motor development , fitness , and bone and skeletal health .
For intensity , light- and moderate-intensity physical activity were not consistently associated with any health indicators , whereas moderate- to vigorous-intensity , vigorous-intensity , and total physical activity were consistently favourably associated with multiple health indicators .
Across study design s , consistent favourable associations with health indicators were observed for a variety of types of physical activity , including active play , aerobic , dance , prone position ( infants ; ≤1 year ) , and structured/organized .
Apart from ≥30 min/day of the prone position for infants , the most favourable frequency and duration of physical activity was unclear .
However , more physical activity appeared better for health .
Conclusions Specific types of physical activity , total physical activity , and physical activity of at least moderate- to vigorous-intensity were consistently favourably associated with multiple health indicators .
Background Given the rapid development during the early years ( 0 - 4 years ) , an underst and ing of the health implication s of physical activity is needed .
The purpose of this systematic review was to examine the relationships between objective ly and subjectively measured physical activity and health indicators in the early years .
Risk factors of obesity in preschool children in China: a population-based case–control study
OBJECTIVE : To identify the risk factors of obesity in preschool children in China . DESIGN : A nationwide case — control study in eight cities in China . SUBJECTS : A total of 748 boys and 574 girls ( age 0.1–6.9 y ) , including the obese and non-obese . One obese child was matched with one non-obese child by sex and age . MEASUREMENTS : Weight , height and other measurements were taken for all the subjects . The information on child activity , feeding pattern and family background was collected by our study team from the parents and the kindergarten teacher . RESULTS : Birth weight ≥ 4.0 kg , high eating speed , obesity among the child 's relatives ≥ 25 % , mother 's body mass index ( BMI ) > 25 kg/m2 and father 's BMI > 25 kg/m2 were identified as the major significant ( P<0.05 ) risk factors of obesity in preschool children in China . CONCLUSION : Family history of obesity , high birth weight and eating speed were identified as the risk factors of obesity in preschool children in China . Our results show the need for family therapy as part of an intervention program for childhood obesity , which includes behavior modification
