Changes in sedentary behaviours and physical activity according to retirement status need to be better defined. Retirement is a critical life period that may influence a number of health behaviours. We assessed past-year sedentary behaviours (television, computer and reading time during leisure, occupational and domestic sitting time, in h/week) and physical activity (leisure, occupational and domestic, in h/week) over 6 years (2000-2001 and 2007) using the Modifiable Activity Questionnaire in 2,841 participants (mean age: 57.3±5.0 y) of the SU.VI.MAX (Supplementation with Antioxidants and Minerals) cohort. Analyses were performed according to retirement status. Subjects retired in 2001 and 2007 (40%) were those who spent most time in sedentary behaviour and in physical activity during and outside leisure (p<0.001). Leisure-time sedentary behaviours increased in all subjects during follow-up (p<0.001), but subjects who retired between 2001 and 2007 (31%) were those who reported the greatest changes (+8.4±0.42 h/week for a combined indicator of leisure-time sedentary behaviour). They also had the greatest increase in time spent in leisure-time physical activity (+2.5±0.2 h/week). In subjects not retired 2001 and 2007 (29%), changes in time spent watching television were found positively associated with an increase in occupational physical activity (p = 0.04) and negatively associated with changes in leisure-time physical activity (p = 0.02). No consistent association between changes in sedentary behaviours and changes in physical activity was observed in subjects retired in 2001 and 2007. Public health interventions should target retiring age populations not only to encourage physical activity but also to limit sedentary behaviours.
根据退休状态，久坐行为和身体活动的变化需要得到更明确的界定。退休是一个关键的人生阶段，可能会影响多种健康行为。我们使用可修改活动问卷，对SU.VI.MAX（补充抗氧化剂和矿物质）队列研究中的2841名参与者（平均年龄：57.3±5.0岁）在6年时间里（2000 - 2001年和2007年）的上一年久坐行为（休闲、职业和家庭久坐时间，以小时/周为单位，包括看电视、使用电脑和阅读时间）和身体活动（休闲、职业和家庭活动，以小时/周为单位）进行了评估。分析是根据退休状态进行的。在2001年和2007年退休的受试者（40%）是在休闲时间内外久坐行为和身体活动时间最长的人群（p<0.001）。在随访期间，所有受试者的休闲时间久坐行为均有所增加（p<0.001），但在2001年至2007年期间退休的受试者（31%）报告的变化最大（休闲时间久坐行为综合指标增加8.4±0.42小时/周）。他们在休闲时间身体活动方面花费的时间增加也最多（增加2.5±0.2小时/周）。在2001年和2007年未退休的受试者（29%）中，看电视时间的变化与职业身体活动的增加呈正相关（p = 0.04），与休闲时间身体活动的变化呈负相关（p = 0.02）。在2001年和2007年退休的受试者中，未观察到久坐行为变化与身体活动变化之间存在一致的关联。公共卫生干预措施应针对退休年龄人群，不仅要鼓励身体活动，还要限制久坐行为。
