一些研究表明，饮食模式，描述饮食频率，一天中饮食事件的时间分布，不吃早餐，以及离家吃饭的频率，可能与肥胖有关。利用1994-1998年血液胆固醇季节性变化研究的数据来评估饮食模式与肥胖的关系。在一年的时间里，在五个等间隔的时间点从499名参与者中收集了三次24小时饮食回忆和体重测量。数据平均为五个时间段，并进行了横断面分析。其他肥胖风险因素，包括年龄，性别，体力活动和总能量摄入的比值比进行了调整。结果表明，每天进食次数越多，肥胖风险越低（四次或四次以上进食与三次或三次以下进食的比值比= 0.55，95%置信区间：0.33，0.91）。相比之下，不吃早餐与肥胖患病率增加相关（比值比= 4.5，95%置信区间：1.57，12.90），因为更频繁地在外面吃早餐或晚餐。有必要在前瞻性研究中进一步调查这些关联。
Some studies have suggested that eating patterns, which describe eating frequency, the temporal distribution of eating events across the day, breakfast skipping, and the frequency of eating meals away from home, may be related to obesity. Data from the Seasonal Variation of Blood Cholesterol Study (1994-1998) were used to evaluate the relation between eating patterns and obesity. Three 24-hour dietary recalls and a body weight measurement were collected at five equally spaced time points over a 1-year period from 499 participants. Data were averaged for five time periods, and a cross-sectional analysis was conducted. Odds ratios were adjusted for other obesity risk factors including age, sex, physical activity, and total energy intake. Results indicate that a greater number of eating episodes each day was associated with a lower risk of obesity (odds ratio for four or more eating episodes vs. three or fewer = 0.55, 95% confidence interval: 0.33, 0.91). In contrast, skipping breakfast was associated with increased prevalence of obesity (odds ratio = 4.5, 95% confidence interval: 1.57, 12.90), as was greater frequency of eating breakfast or dinner away from home. Further investigation of these associations in prospective studies is warranted.
