On the basis of these findings, we recommend that researchers use the EV ActiGraph cut points to estimate time spent in sedentary, light-, moderate-, and vigorous-intensity activity in children and adolescents.

Given the widespread problem of physical inactivity and the continued growth in the prevalence of childhood and adolescent obesity, promotion of regular physical activity among youth has become a public health priority. Abstract: Understanding the social and environmental factors that influence physical activity is important in the development of effective interventions to increase physical activity behavior in children and adolescents.One factor that has received considerable research attention is the influence of parenting practices and behaviors on child physical activity. This review evaluated 103 studies that examined the influence of parental physical activity, parental support for child physical activity, parenting style, and family cohesion on child and adolescent activity behavior. Results showed that parental support was consistently positively and significantly associated with child activity. With respect to the association between parent and child physical activity, there was little evidence of association. Although the evidence linking parenting style and family cohesion with child physical activity was nonsupportive, too few studies have examined these relationships to draw firm conclusions. Priorities for future research and implications for health care professionals are discussed.

In this review, we identify the health benefits associated with physical activity (PA); address the physical activity and sedentary guidelines issued by public health scientists as well as children’s compliance to these guidelines; discuss the importance of motor skill acquisition during early childhood; and identify different settings that contribute to physical activity participation and strategies for improving PA in these settings. Results show that regular participation in PA during childhood has numerous immediate benefits, including positive changes in adiposity, skeletal health, psychological health, and cardiorespiratory fitness. Additionally, motor skill development during early childhood may have immediate health benefits as well as long-lasting effects in adulthood. Furthermore, the benefits of PA during childhood also appear to positively influence adult health outcomes, such as increased bone mineral density. Key environmental settings that have been shown to influence children’s PA behavior include child care, active commuting to and from school, school recess, school physical education, after-school programs, churches, medical settings, and the home environment. Recommendations for practitioners and researchers are discussed.
