Today, approximately one in five United States adolescents age 12 to 19 years is obese and just over a third are either overweight or obese. This study examines how parents and peers influence diet and physical activity behaviors of older adolescents (14–18 years) with overweight or obesity to inform weight management interventions. Adolescent participants included 14 to 18-year-olds with a Body Mass Index (BMI) greater than the 85th percentile for their age and sex who were receiving care in a large healthcare system in Northern California. Adolescents and their parents participated in separate focus groups and interviews (if not able to attend focus groups) that were held at the same time in the same location. We used qualitative thematic analysis to identify common themes discussed in the adolescent and parent focus groups as well as paired analysis of adolescent-parent dyads. Participants included 26 adolescents and 27 parents. Adolescent participants were 14 to 18 years old. Half were female and the participants were almost evenly distributed across year in school. The majority self-identified as White (56%) and Asian (36%).Three themes were identified which included 1) parents overestimated how supportive they were compared to adolescents’ perception 2) parents and adolescents had different views regarding parental influence on adolescent diet and physical activity behaviors 3) parents and adolescents held similar views on peers’ influential role on lifestyle behaviors. Parents’ and adolescents’ differing views suggest that alignment of parent and adolescent expectations and behaviors for supporting effective weight management could be incorporated into interventions.

关于饮食和身体活动的不同观点：青少年与父母的观点

如今，美国大约有五分之一的12至19岁的青少年肥胖，而超过三分之一的青少年则超重或肥胖。这项研究探讨了父母和同龄人如何影响超重或肥胖的老年青少年（14-18岁）的饮食和体育锻炼行为，以指导体重管理干预措施。青少年参与者包括14至18岁的体重指数（BMI）大于其年龄和性别的85％的人，他们正在北加利福尼亚的大型医疗保健系统中接受护理。青少年和他们的父母参加了单独的焦点小组和访谈（如果不能参加焦点小组），这些访谈是在同一地点同时进行的。我们使用定性主题分析来确定在青少年和父母焦点小组中讨论的共同主题，以及对青少年父母双联的成对分析。参加者包括26名青少年和27名父母。青春期参与者为14至18岁。一半是女性，参加者在学校一年中几乎平均分布。多数人自认是白人（56％）和亚洲人（36％）。确定了三个主题，其中包括1）父母高估了他们与青少年感知相比的支持程度2）父母对青少年对父母影响的看法不同饮食和体育锻炼行为3）父母和青少年对同龄人对生活方式行为的影响力持类似观点。
