Combined exposure to several healthy behaviors (HB) is associated with reduced mortality in older adults but its impact on health-related quality of life (HRQL) is uncertain. This is a cohort study of 2,388 individuals aged ≥60 recruited in 2000-2001, whose data were updated in 2003 and 2009. At baseline, participants reported both traditional HB (non-smoking, being very or moderately active, healthy diet) and non-traditional HB (sleeping 7-8 h/d, being seated <8 h/d, and seeing friends every day). HRQL was measured with the SF-36 questionnaire at baseline, in 2003 (short-term) and in 2009 (long-term); a higher score on the SF-36 represents better HRQL. Linear regression models were used to assess the association between HB at baseline and HRQL in 2003 and 2009, with adjustment for the main confounders including baseline HRQL. In the short-term, being physically active, sleeping 7-8 h/d, and being seated <8 h/d was associated with better HRQL. Compared to having ≤1 of these HB, the β (95% confidence interval) for the score on the physical component summary of the SF-36 in 2003 was 1.42 (0.52-2.33) for 2 HB, and 2.06 (1.09-3.03) for 3 HB, p-trend <0.001. Corresponding figures for the mental component summary score were 1.89 (0.58-3.21) for 2 HB and 3.35 (1.95-4.76) for 3 HB, p-trend <0.001. Non-smoking, a healthy diet or seeing friends did not show an association with HRQL. In the long-term, being physically active was the only HB associated with better physical HRQL. As a conclusion, a greater number of HB, particularly more physical activity, adequate sleep duration, and sitting less, were associated with better short-term HRQL in older adults. However, in the long-term, being physically active was the only HB associated with better physical HRQL.
同时践行多种健康行为（HB）与老年人死亡率降低相关，但其对健康相关生活质量（HRQL）的影响尚不确定。这是一项针对2000 - 2001年招募的2388名年龄≥60岁个体的队列研究，其数据于2003年和2009年进行了更新。在基线时，参与者报告了传统的健康行为（不吸烟、非常活跃或适度活跃、健康饮食）和非传统的健康行为（每天睡眠7 - 8小时、每天久坐时间<8小时、每天与朋友见面）。在基线、2003年（短期）和2009年（长期）使用SF - 36问卷测量健康相关生活质量；SF - 36得分越高表示健康相关生活质量越好。使用线性回归模型评估基线时的健康行为与2003年和2009年健康相关生活质量之间的关联，并对包括基线健康相关生活质量在内的主要混杂因素进行调整。在短期内，身体活跃、每天睡眠7 - 8小时以及每天久坐时间<8小时与更好的健康相关生活质量相关。与拥有≤1种这些健康行为相比，2003年SF - 36身体成分总结得分的β（95%置信区间）对于2种健康行为为1.42（0.52 - 2.33），对于3种健康行为为2.06（1.09 - 3.03），p趋势<0.001。心理成分总结得分的相应数字对于2种健康行为为1.89（0.58 - 3.21），对于3种健康行为为3.35（1.95 - 4.76），p趋势<0.001。不吸烟、健康饮食或与朋友见面与健康相关生活质量无关联。从长期来看，身体活跃是唯一与更好的身体健康相关生活质量相关的健康行为。总之，更多的健康行为，特别是更多的身体活动、充足的睡眠时间和更少的久坐时间，与老年人更好的短期健康相关生活质量相关。然而，从长期来看，身体活跃是唯一与更好的身体健康相关生活质量相关的健康行为。
