To determine the impact of uncorrected presbyopia on quality of life in rural Tanzania.
Cross-sectional study.
Population-based sample of 1709 village and town-dwelling adults aged 40 and older in the Kongwa district in rural Tanzania.
Subjects underwent distance and near visual acuity testing to determine presbyopia. A near vision-related quality of life questionnaire was administered by trained interviewers to determine the degree of self-rated difficulty with tasks appropriate to life in a rural African setting, and how much near vision loss contributed to this difficulty.
Near vision-related quality of life.
Complete data were available for 1564 (92%) of the subjects. The prevalence rate of presbyopia was 62%. The majority of presbyopes (94%) did not have corrective near vision glasses. Compared with nonpresbyopes, being presbyopic increased the odds of reporting some difficulty with near vision tasks by 2-fold (odds ratio [OR], 2.04; 95% confidence interval [CI]: 1.57-2.66), odds of reporting moderate difficulty by 5-fold (OR 5.01; 95% CI: 3.19-7.89), and odds of reporting high difficulty by >8-fold (OR 8.52; 95% CI 3.13-23.10). The degree of presbyopia was associated with increasing difficulty with daily tasks (P<0.0001).
This is the first study to demonstrate that uncorrected presbyopia has a significant impact on vision-related quality of life in a rural African setting. The high prevalence of presbyopia, and increased aging of the population in developing countries, suggests that the World Health Organization's Vision 2020 refraction agenda should place greater emphasis on presbyopia.
确定未矫正的老花眼对坦桑尼亚农村地区生活质量的影响。
横断面研究。
以坦桑尼亚农村孔瓜区1709名年龄在40岁及以上的乡村和城镇居民为基础的样本。
受试者接受远视力和近视力测试以确定老花眼。由经过培训的访谈者发放一份与近视力相关的生活质量问卷，以确定在非洲农村环境中，自我评定的适合生活任务的困难程度，以及近视力丧失对这种困难的影响程度。
与近视力相关的生活质量。
1564名（92%）受试者有完整数据。老花眼的患病率为62%。大多数老花眼患者（94%）没有矫正近视力的眼镜。与非老花眼患者相比，患有老花眼使报告近视力任务有一定困难的几率增加了2倍（优势比[OR]，2.04；95%置信区间[CI]：1.57 - 2.66），报告中度困难的几率增加了5倍（OR 5.01；95% CI：3.19 - 7.89），报告高度困难的几率增加了8倍以上（OR 8.52；95% CI 3.13 - 23.10）。老花眼的程度与日常任务难度增加相关（P<0.0001）。
这是第一项表明未矫正的老花眼对非洲农村地区与视力相关的生活质量有重大影响的研究。老花眼的高患病率以及发展中国家人口老龄化加剧，表明世界卫生组织的“视觉2020”屈光不正议程应更加重视老花眼。
