OBJECTIVE
While it is clear that health behaviors are related to self-rated health (SRH), it is less clear if maintaining positive behaviors, or improving, can protect SRH over time.
METHOD
SRH trajectories were modeled in a large representative Australian sample (n=7485 at baseline), of three age cohorts (20-24, 40-44 and 60-64 years at baseline; 1999, 2000 & 2001 respectively), over an 8 year period. Change in smoking, alcohol consumption and physical activity on SRH trajectories were examined, controlling for demographic, physical and mental health factors.
RESULTS
SRH became poorer over time across the sample. Being a non-smoker was associated with more positive SRH levels across all groups. Maintaining or increasing moderate physical activity was associated with less decline in SRH.
CONCLUSIONS
Findings highlight the benefits of positive health behaviors, particularly performing regular physical activity over time, for reducing the risk of subjective health becoming poorer across the adult life course.
目的
虽然健康行为与自评健康（SRH）密切相关，但尚不清楚保持积极的行为或改善行为是否能随着时间的推移保护 SRH。
方法
在一个具有代表性的大型澳大利亚样本中（基线时 n=7485），对三个年龄队列（基线时 20-24 岁、40-44 岁和 60-64 岁；分别为 1999 年、2000 年和 2001 年）进行了 8 年的 SRH 轨迹建模。在控制人口统计学、身体和心理健康因素的情况下，研究了吸烟、饮酒和身体活动的变化对 SRH 轨迹的影响。
结果
整个样本的 SRH 随着时间的推移而变差。不吸烟与所有人群的 SRH 水平呈正相关。保持或增加适度的身体活动与 SRH 下降的减少有关。
结论
这些发现强调了积极健康行为的益处，特别是随着时间的推移定期进行身体活动，可降低主观健康状况在整个成年期恶化的风险。
