International Journal of Behavioral Nutrition and Physical Activity (2015) 12:6 DOI 10.1186/s12966-015-0166-REVIEWOpen AccessUnderstanding gender norms, nutrition, and physical activity in adolescent girls: a scoping reviewRebecca A Spencer1*, Laurene Rehman2 and Sara FL KirkAbstractPublic health is currently focused on childhood obesity, as well as the linked behaviors of physical activity and nutrition. Canadian youth are insufficiently active and microbiolspec.MCHD-0007-2015 don’t meet nutritional recommendations. That is of particular concern for adolescent girls, as they’re significantly less active than boys, become less active as they age, and engage in unhealthy weight control behaviors. The goal of this review will be to ascertain what is recognized in the existing literature about how gender norms are understood in relation towards the health-related behaviors of PA and nutrition in young girls. This scoping review follows the framework of Arksey and O’Malley, involving defining a analysis query, study identification and selection, Stand societal norms and influences. In regard to methodology, a majority charting, interpretation, summarizing, and reporting. In total, 28 documents are reviewed, and qualities are summarized quantitatively and qualitatively. Five major themes are identified: (1) Girls’ relationships with PA are complex and require negotiating gender roles, (two) the literature focuses on dieting rather than nutrition, (3) look and perceptions influence behaviors, (4) “body” focused discourse is considerable to girls’ experiences, and (five) social influences, institutions, and environments are influential and might supply opportunity for future analysis and action. Gaps in the literature are identified and discussed. It is actually concluded that young girls’ activity and nutrition is impacted by gender norms and feminine ideals by means of complex negotiations, perceptions, body-centered discourse, and societal influences. Key phrases: Gender norms, Physical activity, Nutrition, Adolescent girls, Scoping studyPublic wellness is at the moment focused on childhood obesity, with 32 of Canadian youth becoming overweight or obese . In 2006, the direct cost of childhood and adult obesity was an estimated 4 of healthcare expenditures in Canada, a figure that does not include indirect expenses, and that may be expected to improve alongside prices of obesity . Nutrition and physical activity (PA) are two potentially contributing factors to obesity, and while usually looked at as individual behaviors, the population health perspective is increasingly recognizing that broader variables, including obesogenic environments, contribute drastically towards the well being of individuals . Canadian kids s00415-016-8097-0 and youth aren’t receiving adequate nutrition, especially in regard to fruit and s12115-016-0027-3 vegetable consumption [4,5].
