To assess temporal associations between vision and self-rated health.
We examined 3654 Australian residents (82.4% response) aged 49+ years in the Blue Mountains Eye Study, during 1992 to 1994, and re-examined 2334 in 1997 to 1999. Change in vision was defined if baseline and 5-year visual acuity (VA) changed by > or =10 letters (2 lines). Change in self-rated health was defined if overall health ranking (excellent, good, fair, poor) changed by > or =1 step.
Of 2285 participants with data from both examinations, 59.8%, 23.9%, and 16.3% reported unchanged, declined, and improved self-rated health, respectively. Among persons whose self-rated health declined, the proportions with a decline in presenting VA, no change, or improvement were similar (25.2%, 23.8% and 22.5%, respectively, p for trend = 0.5). Among participants with decline, no change, or improvement in self-rated health, a similar magnitude in the age-sex adjusted mean VA decline (-1.0 to -2.7 letters) was observed. After adjusting for age, sex, hospitalizations, and incident chronic conditions, declining VA was not associated with increased decline in 5-year self-rated health (multivariate-adjusted odds ratio 0.99, 95% CI 0.75-1.30).
There were no parallel 5-year changes in self-rated health and vision in this population.
评估视力与自我评估健康状况之间的时间关联。
在1992年至1994年期间，我们对蓝山眼研究中3654名年龄在49岁及以上的澳大利亚居民进行了检查（应答率为82.4%），并于1997年至1999年对其中2334人进行了复查。如果基线视力和5年时的视力（VA）变化≥10个字母（2行），则定义为视力变化。如果总体健康排名（优秀、良好、中等、差）变化≥1级，则定义为自我评估健康状况变化。
在2285名两次检查均有数据的参与者中，分别有59.8%、23.9%和16.3%报告自我评估健康状况未变、下降和改善。在自我评估健康状况下降的人群中，视力下降、不变或改善的比例相似（分别为25.2%、23.8%和22.5%，趋势p值 = 0.5）。在自我评估健康状况下降、不变或改善的参与者中，观察到年龄性别调整后的平均视力下降幅度相似（-1.0至-2.7个字母）。在调整年龄、性别、住院次数和新发慢性病后，视力下降与5年自我评估健康状况下降增加无关（多变量调整比值比为0.99，95%可信区间为0.75-1.30）。
该人群中自我评估健康状况和视力在5年内没有平行变化。
