Obesity and unhealthy eating habits have been associated with irregular sleep-wake patterns during the week, also known as social jet lag. The Mediterranean diet is a healthy pattern related with a better health and sleep quality. However, potential associations with social jet lag remain unexplored. The aim of this study was to examine whether higher social jet lag is linked to lower adherence to the Mediterranean diet and whether it is associated with BMI (Body Mass Index). This cross-sectional study included 534 young adults (18-25 years). Anthropometric parameters, adherence to the Mediterranean diet, chronotype and social jet lag were studied. Our results revealed that individuals with greater social jet lag showed lower adherence to the Mediterranean diet and had a higher BMI. Among the habits that characterized the Mediterranean dietary pattern, we observed that higher social jet lag was significantly associated with a lower intake of fruits and vegetables, as well as skipping breakfast. Hence, the promotion of regular sleep habits together with healthy dietary patterns should be considered for obesity prevention, especially among young adults.
肥胖和不健康的饮食习惯与工作日不规则的睡眠-觉醒模式有关，也称为社交时差。地中海饮食是一种与更好的健康和睡眠质量相关的健康模式。然而，与社交时差相关的潜在关联仍未得到探索。本研究旨在探讨较高的社交时差是否与较低的地中海饮食依从性相关，以及是否与 BMI（体重指数）相关。这项横断面研究纳入了 534 名年轻成年人（18-25 岁）。研究了人体测量参数、地中海饮食的依从性、睡眠类型和社交时差。我们的结果表明，社交时差较大的个体表现出较低的地中海饮食依从性，并且 BMI 较高。在特征为地中海饮食模式的习惯中，我们观察到较高的社交时差与水果和蔬菜摄入量较低以及不吃早餐显著相关。因此，应该考虑促进规律的睡眠习惯和健康的饮食模式，以预防肥胖，尤其是在年轻人中。
