This study investigated the association between physical activity (PA) and midlife income. The population-based data comprised employed members of the Northern Finland Birth Cohort 1966 (N = 2797). Using binned scatterplots and polynomial regressions, we evaluated the association between accelerometer-measured moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) at 46 years old and register-based income at 50 years old. The models were adjusted for sex, marital status, number of children, education, adolescent PA, occupational physical strenuousness, and time preference. We found MPA (p < 0.001), VPA (p < 0.05), and MVPA (p < 0.001) to associate curvilinearly with income. In subgroup analyses, a curvilinear association was found between MPA (p < 0.01) and MVPA (p < 0.01) among those with physically strenuous work, VPA among all females (p < 0.01) and females with physically light work (p < 0.01), and MPA and MVPA among all males and males with physically strenuous work (p < 0.05; p < 0.01; p < 0.05; p < 0.05, respectively) and income. The highest income benefits occurred at PA volumes higher than current PA guidelines. Linear associations between PA and income were found among females for MPA (p < 0.05) and MVPA (p < 0.05), among those with physically light work for MPA (p < 0.05), VPA (p < 0.05), and MVPA (p < 0.05), and among females with physically strenuous work for VPA (p < 0.05). We conclude that PA up to the current recommended level is associated with income, but MPA exceeding 505.4 min/week, VPA exceeding 216.4 min/week, and MVPA exceeding 555.0 min/week might have a negative association with income.
本研究旨在探讨体力活动（PA）与中年收入之间的关系。该基于人群的数据来自芬兰北部出生队列 1966 年的在职成员（N=2797）。使用分组散点图和多项式回归，我们评估了 46 岁时使用加速度计测量的中度 PA（MPA）、剧烈 PA（VPA）和中高强度 PA（MVPA）与 50 岁时的注册收入之间的关系。模型调整了性别、婚姻状况、子女数量、教育程度、青少年 PA、职业体力强度和时间偏好。我们发现 MPA（p<0.001）、VPA（p<0.05）和 MVPA（p<0.001）与收入呈曲线相关。在亚组分析中，我们发现体力劳动强度较高人群的 MPA（p<0.01）和 MVPA（p<0.01）、所有女性的 VPA（p<0.01）和体力劳动强度较轻的女性的 VPA（p<0.01）、所有男性和体力劳动强度较高的男性的 MPA 和 MVPA（p<0.05；p<0.01；p<0.05；p<0.05）与收入之间呈曲线相关。高于当前 PA 指南的 PA 量与最高收入获益相关。在女性中，我们发现 MPA（p<0.05）和 MVPA（p<0.05）与收入呈线性相关，在体力劳动强度较轻的人群中，MPA（p<0.05）、VPA（p<0.05）和 MVPA（p<0.05）与收入呈线性相关，在体力劳动强度较高的女性中，VPA（p<0.05）与收入呈线性相关。我们的结论是，达到当前推荐水平的 PA 与收入相关，但 MPA 超过 505.4 分钟/周、VPA 超过 216.4 分钟/周和 MVPA 超过 555.0 分钟/周可能与收入呈负相关。
