中老年人群视功能和生存质量的研究

目的 评价中老年人群中视功能损害的主观视功能和生存质量。方法 对广东省斗门县随机整群抽样法抽取的所有５０岁以上的中老年人进行问卷调查,由５名问卷调查员,使用视功能和生存质量（ｖｉｓｕａｌ ｆｕｎｃｔｉｏｎ ａｎｄ ｑｕａｌｉｔｙ ｏｆ ｌｉｆｅ,ＶＦ ａｎｄ ＱＯＬ）问卷,对所有至少１只眼日常生活视力低于０．１的受检者（视功能损害组）和部分双眼视力均高于０．３（正常对照组）的受检者进行问卷调查。结

A study on visual function and quality of life in elderly population

OBJECTIVE: To evaluate the visual impairment by visual function and quality of life assessment in elderly population. METHOD: All subjects aged >or= 50 years were identified by randomly clustering sampling. Visual Function and Quality of Life Questionnaire (VF/QOL) was administered by 5 interviewers for all subjects with presenting visual acuity less than 0.1 in at least one eye (as visual impairment group) and part of the subjects with presenting visual acuity better than 0.3 in both eyes (as control group). RESULTS: Five hundred and thirty-five eligible visual impairment subjects (90.8%) and 119 control subjects were successfully interviewed. In a 0 - 100 scores' scale, the subjective VF and QOL mean scores were 51.0 and 65.9 respectively. The mean score was correlated with age, sex and education. Mean VF and QOL scores decreased from 84.4 and 93.4 to 14.6 and 31.2 along with the visual status worsening from normal to severe blindness respectively. In stepwise linear regression model, the VF and QOL scores were significantly correlated with age and education instead of sex. CONCLUSIONS: In elderly population with visual impairment, subjective visual function and quality of lift status are deteriorated substantially. Their scores are significantly correlated with age and education.
