背景：体力活动（PA）、久坐行为（SB）、睡眠和饮食都与慢性病风险增加有关。季节性往往被忽视，因为它是成年人这些行为的决定因素。目前，还没有研究同时监测这些行为在英国成年人，以评估季节性variation.Aim：本研究调查是否PA，SB，睡眠和饮食不同的季节在英国成年人。主题和方法：46名成年人（72%女性;年龄-41.7 +/- 14.4岁，BMI -24.9 +/- 4.4 kg/m2）完成了4个7天的监测期;一年中每个季节一次。ActiGraph GT 1 M用于监测PA和SB。每日睡眠日记监测卧床时间（TIB）和总睡眠时间（TST）。欧洲癌症前瞻性调查（EPIC）食物频率问卷（FFQ）评估饮食。重复测量方差分析用于确定行为的季节差异。结果：光照强度PA在夏季和春季显著较高（p
Background: Physical activity (PA), sedentary behaviour (SB), sleep and diet have all been associated with increased risk for chronic disease. Seasonality is often overlooked as a determinant of these behaviours in adults. Currently, no study has simultaneously monitored these behaviours in UK adults to assess seasonal variation.Aim: The present study investigated whether PA, SB, sleep and diet differed over season in UK adults.Subjects and methods: Forty-six adults (72% female; age -41.7 +/- 14.4 years, BMI -24.9 +/- 4.4 kg/m 2) completed four 7-day monitoring periods; one during each season of the year. The ActiGraph GT1M was used to monitor PA and SB. Daily sleep diaries monitored time spent in bed (TIB) and total sleep time (TST). The European Prospective Investigation of Cancer (EPIC) food frequency questionnaire (FFQ) assessed diet. Repeated measures ANOVAs were used to identify seasonal differences in behaviours.Results: Light-intensity PA was significantly higher in summer and spring (p
