Evidence assessing the relationship between chronotype and disordered eating in adolescents is scarce. The current study tried to evaluate the association between chronotype and disordered eating in a sample of Spanish adolescents.
This secondary cross-sectional study analyzed data from the Eating Healthy and Daily Life Activities (EHDLA) study. The sample consisted of 703 adolescents (56.3% girls) aged between 12 and 17 years from the (Region of Murcia, Spain). Chronotype was assessed using the Morningness/Eveningness Scale in Children (MESC). Disordered eating was evaluated by two psychologists using the Sick, Control, One, Fat, and Food (SCOFF) questionnaire.
Adolescents with an eveningness chronotype showed a higher SCOFF score (estimated marginal mean [] = 1.1; 95% confidence interval [CI] 0.7 to 1.5) in comparison with adolescents with a morningness chronotype ( = 0.7; 95% CI 0.5 to 0.8) ( = 0.010), as well as with those with an intermediate chronotype ( = 0.6; 95% CI 0.5 to 0.8) ( = 0.032). A higher predictive probability of having disordered eating was identified in adolescents with an eveningness chronotype (39.5%; 95% CI 22.8% to 59.1%), compared to adolescents with an intermediate chronotype (14.9%; 95% CI 10.8% to 20.1%) ( = 0.008) and with their counterparts with a morningness chronotype (16.9%; 95% CI 11.6% to 24.0%) ( = 0.021).
This study reveals that adolescents with an eveningness chronotype are more likely to exhibit disordered eating behaviors compared to those with morningness or intermediate chronotypes. These findings highlight the importance of considering chronotype in adolescent health, particularly in developing targeted interventions to prevent eating disorders.
评估青少年的昼夜型与饮食障碍之间关系的证据有限。本研究试图评估西班牙青少年样本中昼夜型与饮食障碍之间的关联。
本二次横断面研究分析了“健康饮食与日常生活活动（EHDLA）”研究的数据。该样本包括来自西班牙（穆尔西亚地区）年龄在 12 至 17 岁的 703 名青少年（56.3%为女孩）。使用儿童晨型/晚型量表（MESC）评估昼夜型。两位心理学家使用 Sick、Control、One、Fat、and Food（SCOFF）问卷评估饮食障碍。
与晨型青少年（ = 0.7；95%置信区间 0.5 至 0.8）（ = 0.010）和中间型昼夜型青少年（ = 0.6；95%置信区间 0.5 至 0.8）（ = 0.032）相比，晚型昼夜型青少年的 SCOFF 评分更高（估计边缘均值[]=1.1；95%置信区间 0.7 至 1.5）。晚型昼夜型青少年饮食障碍的预测概率更高（39.5%；95%置信区间 22.8%至 59.1%），而中间型昼夜型青少年（14.9%；95%置信区间 10.8%至 20.1%）（ = 0.008）和晨型昼夜型青少年（16.9%；95%置信区间 11.6%至 24.0%）（ = 0.021）。
本研究表明，与晨型或中间型昼夜型青少年相比，晚型昼夜型青少年更有可能出现饮食障碍行为。这些发现强调了在青少年健康中考虑昼夜型的重要性，特别是在制定针对饮食障碍的干预措施时。
