We aim to describe temporal eating patterns in a population of adults with overweight or obesity. In this cross-sectional analysis, data were combined from two separate pilot studies during which participants entered the timing of all eating occasions (>0 kcals) for 10-14 days. Data were aggregated to determine total eating occasions, local time of the first and last eating occasions, eating window, eating midpoint, and within-person variability of eating patterns. Eating patterns were compared between sexes, as well as between weekday and weekends. Participants ( = 85) had a median age of 56 ± 19 years, were mostly female (>70%), white (56.5%), and had a BMI of 31.8 ± 8.0 kg/m. The median eating window was 14 h 04 min [12 h 57 min-15 h 21 min], which was significantly shorter on the weekend compared to weekdays ( < 0.0001). Only 13.1% of participants had an eating window <12 h/d. Additionally, there was greater irregularity with the first eating occasion during the week when compared to the weekend ( = 0.0002). In conclusion, adults with overweight or obesity have prolonged eating windows (>14 h/d). Future trials should examine the contribution of a prolonged eating window on adiposity independent of energy intake.
我们旨在描述超重或肥胖成年人的时间性进食模式。在这项横断面分析中，数据来自两项单独的初步研究，研究期间参与者记录了 10-14 天内所有进食的时间（>0 千卡）。数据汇总以确定总进食次数、首次和末次进食的当地时间、进食窗口、进食中点和个体内进食模式的变异性。比较了不同性别和工作日与周末之间的进食模式。参与者（n=85）的中位年龄为 56±19 岁，主要为女性（>70%），白人（56.5%），BMI 为 31.8±8.0kg/m。中位进食窗口为 14 h 04 min[12 h 57 min-15 h 21 min]，与工作日相比，周末的进食窗口显著缩短（<0.0001）。仅有 13.1%的参与者的进食窗口<12 h/d。此外，与周末相比，一周内首次进食的时间更不规则（=0.0002）。总之，超重或肥胖的成年人的进食窗口较长（>14 h/d）。未来的试验应独立于能量摄入，研究延长的进食窗口对肥胖的影响。
