We examined the relationship between vision impairment (VI) and new-onset frailty among non-frail Mexican American older adults (≥70 years) at baseline and determined the differential impact of VI on each frailty criteria. Data were from an 18-year prospective cohort from the Hispanic Established Population for the Epidemiologic Study of the Elderly (1998/1999, = 1072 to 2016, = 175). Frailty was defined as ≥3 criteria: unintentional weight loss of >10 pounds, weakness, exhaustion, low physical activity, and slowness. VI was defined as difficulty in recognizing a friend at arm's length's away, across the room, or across the street. We found that participants with VI (near or distant) and distant VI had greater odds of frailty (near or distant VI, OR = 1.89, 95% CI = 1.30-2.73 and distant VI, OR = 1.95, 95% CI = 1.34-2.86, respectively) after controlling for covariates over time. Early screening (optimal management) of VI may prevent or delay onset of frailty among older Mexican Americans.
我们考察了无虚弱的墨西哥裔美国老年人（≥70 岁）基线时视力障碍（VI）与新发虚弱之间的关系，并确定了 VI 对每个虚弱标准的不同影响。数据来自西班牙裔老年人流行病学研究中的一个 18 年前瞻性队列（1998/1999 年，n=1072 至 2016 年，n=175）。虚弱定义为≥3 项标准：非故意体重减轻>10 磅、乏力、疲惫、低体力活动和缓慢。VI 定义为无法识别在手臂距离、房间对面或街对面的朋友。我们发现，有近距或远距 VI 的参与者发生虚弱的几率更高（近距或远距 VI，OR=1.89，95%CI=1.30-2.73 和远距 VI，OR=1.95，95%CI=1.34-2.86，分别），这与随着时间的推移控制协变量有关。对 VI 进行早期筛查（最佳管理）可能有助于预防或延缓老年墨西哥裔美国人虚弱的发生。
