This study examined adherence to a personalized, community-based exercise intervention by sedentary adolescents with type 1 or type 2 diabetes or those with obesity.
We conducted a pretest-posttest investigation to explore the application of an individualized exercise prescription based upon current fitness level for 39 adolescents (20 with type 1 diabetes, 9 with type 2 diabetes, and 10 obese) over 16 weeks in community settings. Subjects were recruited from a university-based pediatric endocrinology clinic in the southwestern United States. Adherence to the exercise prescription was monitored using accelerometers over the entire intervention period.
Moderate-to-vigorous physical activity (MVPA) levels significantly increased over sedentary baseline values (p < .001), but the average of 42.5 ± 22.1 min/day of MVPA determined at the end of the study was still less than the recommended 60 min/day. Perceptions of health were significantly increased for the total group following the intervention (p = .008). For those with type 1 diabetes, there was a significant association between MVPA duration and percentage change in HbA1c (r = -.526, p = .02).
Recruitment and retention of adolescent participation in daily exercise is challenging. Personalized approaches that include adolescent choices with family support and ongoing motivation can improve individual exercise adherence and a sense of personal health.
本研究考察了 39 名青少年（10 名肥胖、9 名 2 型糖尿病、20 名 1 型糖尿病）在社区环境中接受个性化的、基于社区的运动干预方案的依从性。
我们进行了一项预测试-后测试调查，以探索基于当前健康水平为 16 周的个体运动处方在社区环境中的应用。受试者是从美国西南部的一所大学儿科内分泌诊所招募的。在整个干预期间，使用加速度计监测对运动处方的依从性。
中度至剧烈体力活动（MVPA）水平显著高于久坐不动的基线值（p <.001），但研究结束时确定的 42.5 ± 22.1 分钟/天的平均 MVPA 仍低于推荐的 60 分钟/天。干预后，总人群的健康感知显著增加（p =.008）。对于 1 型糖尿病患者，MVPA 持续时间与 HbA1c 的百分比变化之间存在显著相关性（r = -.526，p =.02）。
招募和保留青少年参与日常锻炼具有挑战性。个性化的方法包括青少年的选择，需要家庭支持和持续的激励，可以提高个体的运动依从性和个人健康感。
