The frequency of obesity and poor sleep quality among adolescents is increasing and causes many chronic problems. The objective was to investigate the correlation between body mass index (BMI), sleep quality, sleep duration and social jet lag (SJL) among adolescents.
This study was cross-sectional. A cohort of 416 adolescents, ranging in age from 12 to 18 years participated in the study. Adolescents were divided into three groups according to BMI standard deviation score (SDS): adolescents with normal weight, adolescents with overweight and adolescents with obesity. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used to determine the sleep quality of the adolescents. The calculation of SJL and sleep-corrected SJL was performed.
The mean age of the adolescents was 15.0±2.9 years. There were 222 males (53.4%). SJL and PSQI scores were significantly higher in the adolescents with obesity compared to the adolescents with normal weight and overweight (p<0.001). An analysis of the relationship between the PSQI and BMI SDS revealed a significant positive correlation (r=0.667; p<0.001).
Adolescents with obesity have poorer sleep quality and a longer duration of SJL compared to adolescents with normal-weight. Moreover, increased SJL was linked to an increase in BMI. Maintaining good sleep quality and reducing SJL may help reduce the risk of obesity.
青少年肥胖和睡眠质量差的发生率正在上升，并引发许多慢性问题。本研究旨在探讨青少年体重指数（BMI）、睡眠质量、睡眠时间与社会时差（SJL）之间的相关性。
本研究为横断面研究。416名年龄在12至18岁之间的青少年参与了该研究。青少年根据BMI标准差评分（SDS）分为三组：体重正常的青少年、超重的青少年和肥胖的青少年。采用匹兹堡睡眠质量指数（PSQI）问卷来确定青少年的睡眠质量。进行了SJL和睡眠校正SJL的计算。
青少年的平均年龄为15.0±2.9岁。男性有222名（53.4%）。与体重正常和超重的青少年相比，肥胖青少年的SJL和PSQI评分显著更高（p<0.001）。PSQI与BMI SDS之间的关系分析显示出显著的正相关（r=0.667；p<0.001）。
与体重正常的青少年相比，肥胖青少年的睡眠质量更差，SJL持续时间更长。此外，SJL增加与BMI升高有关。保持良好的睡眠质量和减少SJL可能有助于降低肥胖风险。
