目的:本研究旨在调查来自ValledeRicote(穆尔西亚地区,西班牙)。我们探讨了SJL与体重指数(BMI)z评分之间的关系,腰围,和身体脂肪百分比,以及体重过重的可能性,肥胖,西班牙青少年样本中的腹部肥胖。
方法:使用饮食健康和日常生活活动(EHDLA)项目的数据进行了一项横断面研究,其中包括847名12-17岁的西班牙青少年。根据工作日和周末之间睡眠模式的差异评估SJL。肥胖相关指标,如BMIz评分,腰围,身体脂肪百分比,超重,肥胖,和腹部肥胖进行测量。使用具有高斯分布或二项分布的广义线性模型来分析SJL和肥胖相关结果之间的关联。调整潜在的混杂因素。
结果:分析显示SJL和BMIz-score之间存在显著关联(未标准化的β系数[B]=0.15,95%CI:0.05至0.25,p=0.003),腰围(B=1.03,95%CI:0.39至1.67,p=0.002),和体脂百分比(B=0.83,95%CI:0.31至1.43,p=0.008)。此外,超重的比值比(OR)(OR=1.35,95%CI:1.16至1.57;p<0.001),肥胖(OR=1.59,95%CI:1.26至2.00;p<0.001),和腹部肥胖(OR=1.46,95%CI:1.23至1.72;p<0.001)随着SJL每增加60分钟而显着增加。
结论:这项研究指出,工作日和周末(SJL)的睡眠时间错位与较高的BMIz得分显着相关,腰围,身体脂肪百分比,体重过重的几率更高,肥胖,青少年的腹部肥胖,男孩比女孩更重要。这些发现强调了在该人群中预防和管理肥胖及其相关代谢紊乱中解决昼夜节律失调的重要性。
OBJECTIVE: This study aimed to investigate the association between social jetlag (SJL) and obesity-related outcomes among adolescents from Valle de Ricote (Region of Murcia, Spain). We explored the relationship between SJL and body mass index (BMI) z-score, waist circumference, and body fat percentage, as well as the odds of having excess weight, obesity, and abdominal obesity in a sample of Spanish adolescents.
METHODS: A cross-sectional study was conducted using data from the Eating Healthy and Daily Life Activities (EHDLA) project, which included 847 Spanish adolescents aged 12-17 years. SJL was assessed based on the differences in sleep patterns between weekdays and weekends. Obesity-related indicators such as BMI z-score, waist circumference, body fat percentage, excess weight, obesity, and abdominal obesity were measured. Generalized linear models with a Gaussian or binomial distribution were used to analyze the associations between SJL and obesity-related outcomes, adjusting for potential confounders.
RESULTS: The analysis revealed significant associations between SJL and BMI z-score (unstandardized beta coefficient [B] = 0.15, 95% CI: 0.05 to 0.25, p = 0.003), waist circumference (B = 1.03, 95% CI: 0.39 to 1.67, p = 0.002), and body fat percentage (B = 0.83, 95% CI: 0.31 to 1.43, p = 0.008). Additionally, the odds ratios (ORs) for excess weight (OR = 1.35, 95% CI: 1.16 to 1.57; p < 0.001), obesity (OR = 1.59, 95% CI: 1.26 to 2.00; p < 0.001), and abdominal obesity (OR = 1.46, 95% CI: 1.23 to 1.72; p < 0.001) increased significantly with each 60 min increment in SJL.
CONCLUSIONS: This study pointed out that the misalignment of sleeping times during weekdays and weekends (SJL) is significantly associated with higher BMI z-scores, waist circumference, body fat percentage, and higher odds of excess weight, obesity, and abdominal obesity among adolescents, being more significant in boys than in girls. These findings highlight the importance of addressing circadian misalignment in the prevention and management of obesity and its related metabolic disorders in this population.
