The sample included adolescents aged 10-16 years. Accelerometry was used to measure PA and sleep over 7 days, 24 h/d. The PA guideline was defined as ≥60 min/d of moderate-to-vigorous PA. The sleep guideline was 9-11 hours (10-13 years) or 8-10 hours (14-16 years) per night. The dietary guideline was based on the Healthy Eating Index calculated from dietary recalls. Cardiometabolic risk factors and adiposity were assessed in an in-patient setting. Linear regression was used to examine the association between meeting each guideline and cardiometabolic risk factors/adiposity, adjusted for confounders and meeting other guidelines.
Of the 342 participants, 251 (73%) provided complete measurements. Adolescents were 12.5 ± 1.9 years (African American [37%] and white [57%], girls [54%], and overweight or obesity [48%]). Half met the sleep guideline (52%), few met the PA guideline (11%), and the top quintile was preselected as meeting the diet guideline (20%). Most met one (47%) or no guidelines (35%), and few met multiple guidelines (18%). Meeting the PA guideline was associated with lower cardiometabolic risk factors and adiposity (p < .05 for all). Compared with meeting no guidelines, those who met multiple guidelines had lower cardiometabolic risk factors and adiposity (p < .05 for all).
Few met the PA or multiple guidelines, and those not meeting guidelines were associated with adverse cardiometabolic factors and adiposity. Multidisciplinary strategies for improving multiple behaviors are needed to improve adolescent health.
样本包括10-16岁的青少年。使用加速度测量法测量7天的PA和睡眠,24h/d。PA指南定义为≥60分钟/天的中度至重度PA。睡眠指南是每晚9-11小时(10-13岁)或8-10小时(14-16岁)。饮食指南基于从饮食召回计算的健康饮食指数。在住院患者环境中评估心脏代谢危险因素和肥胖。线性回归用于检查满足每个指南与心脏代谢危险因素/肥胖之间的关联。针对混杂因素进行了调整,并符合其他指导方针。
在342名参与者中,251(73%)提供了完整的测量。青少年为12.5±1.9岁(非裔美国人[37%]和白人[57%],女孩[54%],和超重或肥胖[48%])。一半符合睡眠指南(52%),很少有人符合PA指南(11%),并且前五分之一被预选为符合饮食指南(20%)。大多数人符合一项指导方针(47%)或没有指导方针(35%),很少有人符合多项指导方针(18%)。符合PA指南与较低的心脏代谢危险因素和肥胖相关(均p<0.05)。与不符合准则相比,符合多项指南的患者心脏代谢危险因素和肥胖发生率较低(均p<.05).
很少有人符合PA或多个准则,那些不符合指南的患者与不良心脏代谢因素和肥胖相关.需要改善多种行为的多学科策略来改善青少年健康。
