Various eating behaviors have been linked with body weight management. However, combined effects of major eating behaviors are not fully understood. This study aimed to clarify the association of the combination of eating quickly (EQ), late evening meals (LEM), and skipping breakfast (SB) with being overweight.
A cross-sectional study with standardized questions for EQ, LEM, and SB was conducted. Stratified random sampling of 5% of residents aged 20 to 80years was surveyed in a city in northeast Japan in 2011, and 4249 (84.9%) residents were analyzed. Association of combinations of eating behaviors on being overweight (BMI (kg/m(2)≥25.0)) was estimated by using logistic analysis, and odds ratio (OR) and 95% confidential interval were calculated after adjustment for potential covariates.
LEM, SB, or a combination of LEM and SB was not significantly associated with being overweight. However, the combination of EQ or only EQ was significantly associated with being overweight. As the number of eating behavior practices increased, there was a linear increase in OR for being overweight. The OR of all three combined eating behaviors was higher than that of any combined two behaviors or of each behavior.
This study result supports the evidence that EQ increases the risk of being overweight whether by itself or in combinations with LEM and/or SB. However, only LEM or only SB did not increase the risk of being overweight.
多种饮食行为与体重管理相关。然而，主要饮食行为的综合影响尚未完全明确。本研究旨在阐明吃饭快（EQ）、晚餐过晚（LEM）和不吃早餐（SB）三者结合与超重之间的关联。
开展一项采用针对EQ、LEM和SB的标准化问题的横断面研究。2011年，在日本东北部某城市对20至80岁居民进行5%的分层随机抽样调查，对4249名（84.9%）居民进行分析。通过逻辑分析评估饮食行为组合与超重（体重指数（BMI，kg/m²）≥25.0）之间的关联，并在对潜在协变量进行调整后计算比值比（OR）和95%置信区间。
LEM、SB或LEM与SB的组合与超重无显著关联。然而，EQ或仅EQ的组合与超重显著相关。随着饮食行为习惯数量的增加，超重的OR呈线性上升。三种饮食行为组合的OR高于任何两种行为组合或每种行为的OR。
本研究结果支持以下证据，即无论单独出现还是与LEM和/或SB组合出现，EQ都会增加超重风险。然而，仅LEM或仅SB并不会增加超重风险。
