Retirement is a major life transition affecting health behaviors. The aim of this study was to examine within-individual changes in body mass index (BMI) during transition from full-time work to statutory retirement by sex and physical work characteristics.
A multiwave cohort study repeated every 4 years and data linkage to records from retirement registers. Participants were 5426 Finnish public-sector employees who retired on a statutory basis in 2000-2011 and who reported their body weight one to three times prior to (w, w, w), and one to three times after (w, w, w) retirement.
During the 4-year retirement transition (w, vs. w) men showed decline in BMI, which was most marked among men with sedentary work (-0.18 kg/m, 95% CI -.30 to -0.05). In contrast, BMI increased during retirement transition in women and was most marked among women with diverse (0.14 kg/m, 95% CI 0.08 to 0.20) or physically heavy work (0.31 kg/m, 95% CI 0.16 to 0.45). Physical activity during leisure time or commuting to work, alcohol consumption or smoking did not explain the observed changes during retirement transition.
In this study statutory retirement was associated with small changes in BMI. Weight loss was most visible in men retiring from sedentary jobs and weight gain in women retiring from diverse and physically heavy jobs.
退休是影响健康行为的重大生活转变。本研究的目的是按性别和体力工作特征，研究从全职工作过渡到法定退休期间个体体重指数（BMI）的变化。
一项每4年重复一次的多波队列研究，并与退休登记记录进行数据关联。参与者为5426名芬兰公共部门员工，他们于2000年至2011年依法退休，在退休前报告了一至三次体重（w、w、w），退休后报告了一至三次体重（w、w、w）。
在4年的退休过渡期间（w对w），男性的BMI下降，这在从事久坐工作的男性中最为明显（-0.18kg/m²，95%CI -0.30至-0.05）。相比之下，女性在退休过渡期间BMI增加，在从事多样化工作（0.14kg/m²，95%CI 0.08至0.20）或体力繁重工作的女性中最为明显（0.31kg/m²，95%CI 0.16至0.45）。休闲时间或通勤期间的身体活动、饮酒或吸烟并不能解释退休过渡期间观察到的变化。
在本研究中，法定退休与BMI的微小变化有关。从事久坐工作的退休男性体重减轻最为明显，从事多样化和体力繁重工作的退休女性体重增加。
