There is a lack of consistency in the literature that shows a relationship between chronotype, habits of eating and obesity in Iranian adults. This cross-sectional study was conducted on 850 individuals aged ≥ 18 years, selected from health houses of Tehran, Iran. Chronotype was assessed by Horne and Ostberg morningness-eveningness questionnaire. Specific eating habits, including breakfast skipping, intakes of fruits and vegetables, fast food, processed meats, soft drinks, coffee and tea, were assessed by dietary recalls. Weight, height, BMI, waist circumference, waist to hip ratio, waist to height ratio, visceral adiposity index, body roundness index and body adiposity index were based on measured values. We used logistic regression to investigate the association between chronotypes and anthropometric measures as well as eating habits. Morning- and intermediate/evening-type chronotypes accounted for 51·4 and 48·6 % of the total individuals, respectively. Moreover, intermediate/evening-type chronotypes were shown to have a lower education of diploma (53 %), employed (49·9 %) and smokers (11·6 %) compared with morning types (both sexes). We found that intermediate/evening-type chronotypes might not be significantly related to higher anthropometric measures and following unhealthy eating habits after controlling for confounders in men and women (all > 0·05). Overall, both anthropometric measures and specific eating habits were not related to chronotype among Iranian adults. Further studies are needed to clarify these relations and to consider sleep disturbances.
在表明伊朗成年人的昼夜节律类型、饮食习惯与肥胖之间存在关联的文献中，缺乏一致性。本横断面研究对850名年龄≥18岁的个体进行，这些个体选自伊朗德黑兰的健康中心。昼夜节律类型通过霍恩和奥斯特伯格晨型-夜型问卷进行评估。特定的饮食习惯，包括不吃早餐、水果和蔬菜的摄入量、快餐、加工肉类、软饮料、咖啡和茶，通过饮食回忆进行评估。体重、身高、体重指数、腰围、腰臀比、腰高比、内脏脂肪指数、身体圆润度指数和身体脂肪指数基于测量值。我们使用逻辑回归来研究昼夜节律类型与人体测量指标以及饮食习惯之间的关联。晨型和中间/夜型昼夜节律类型分别占总个体数的51.4%和48.6%。此外，与晨型（男女皆是）相比，中间/夜型昼夜节律类型的个体显示出较低的文凭教育程度（53%）、就业比例（49.9%）和吸烟比例（11.6%）。我们发现，在控制了男性和女性的混杂因素后，中间/夜型昼夜节律类型可能与较高的人体测量指标以及不健康的饮食习惯没有显著关联（所有P>0.05）。总体而言，在伊朗成年人中，人体测量指标和特定的饮食习惯均与昼夜节律类型无关。需要进一步的研究来阐明这些关系并考虑睡眠障碍。
