PURPOSE: To examine the association between visual impairment (VI) and morbidity. METHODS: Using pooled, annual population-based household interview survey data (n = 140,366) from the 1986-1996 National Health Interview Survey, covariate-adjusted, gender and age group specific logistic regression analyses were used to examine associations between VI and five morbidity indicators: restricted activity days, bed rest days, doctor visits, hospitalizations, and self-rated health. RESULTS: After controlling for educational status, race and the number of reported non-ocular health conditions, fair or poor health status (compared to excellent, very good, or good health status) was generally more strongly associated with severe, bilateral VI (range of odds ratios [OR's]: 2.14-7.24) than with some VI (OR's: 1.45-2.21). Severe, bilateral VI was also associated with more frequent doctor and hospital visits among adults 18-64 years of age (range of OR's: 1.69-3.34), and restricted activity and bed rest days among males 45 years and older (range of OR's: 1.95-3.69). CONCLUSIONS: The present findings, in conjunction with other studies documenting the impact of VI on morbidity outcomes, indicate that an increased focus on the provision of eye care services will be necessary to address the growing burden of VI in aging societies.  相似文献

PURPOSE: To examine the relationship between reported visual impairment and unintentional injury mortality. DESIGN: Mortality linkage study of a population-based survey. METHODS: Mortality linkage through 1997 of 116,796 adult participants, aged 18 years and older, from the 1986 to 1994 National Health Interview Survey was analyzed with respect to reported visual impairment using Cox regression models.The average follow-up was 7.0 years, and 295 unintentional injury deaths were identified. After controlling for survey design, age, sex, and the presence and number of eye diseases, participants with severe, bilateral visual impairment were at increased risk of death relative to participants without visual impairment (hazard ratio: 7.4; 95% confidence interval: 3.0-17.8). CONCLUSIONS: Our data provide evidence that severe, bilateral visual impairment is associated with an increased risk of unintentional mortality among adults in the United States.  相似文献

OBJECTIVE: Associations between glaucoma and survival have not been studied extensively, in part, because of the relatively low prevalence of this condition. This study examines associations between self-reported glaucoma and mortality in a nationally representative sample of U.S. adults. DESIGN: Annual cross-sectional multistage area probability survey of the U.S. civilian noninstitutionalized population living at addressed dwellings. PARTICIPANTS: Mortality linkage with >96% of participants from the 1986 to 1994 National Health Interview Survey was performed by the National Center for Health Statistics through 1997. Complete data were available on 116796 adults >or=018 years old. METHODS: Adults within randomly selected households were administered a chronic conditions list that included questions about glaucoma and visual impairment. Proxy information on these conditions was obtained when household members were unavailable for interview. Statistical methods included Cox regression models with adjustments for covariates, as well as for the complex sample survey design. MAIN OUTCOME MEASURE: All-cause mortality and cardiovascular and cancer mortality. RESULTS: A total of 1559 (1.3%) glaucoma cases were reported. Nearly 19% of participants with reported glaucoma also had reported visual impairment (n = 303). Mortality linkage identified 8949 deaths; the average follow-up was 7.0 years. After controlling for survey design, gender, age, race, marital status, education level, and self-rated health, participants with reported glaucoma but without reported visual impairment were at significantly increased risk of death relative to participants without reported glaucoma, irrespective of visual impairment status (hazard ratio [HR], 1.35; 95% confidence interval [CI], 1.19-1.53); similar associations were found for participants with reported glaucoma and visual impairment vs. participants with no reported glaucoma (HR, 1.39; 95% CI, 1.14-1.71). An increased risk of cardiovascular disease mortality was found for participants with reported glaucoma both without (HR, 1.31; 95% CI, 1.11-1.55) and with (HR, 1.53; 95% CI, 1.15-2.05) reported visual impairment. Risk of mortality due to cancer was increased only in participants with reported glaucoma but without reported visual impairment (HR, 1.57; 95% CI, 1.25-1.98); this association was stronger when the mortality analysis was restricted to cancers amenable to early screening, including breast, cervical, colon, and prostate cancer (HR, 1.99; 95% CI, 1.41-2.81). CONCLUSIONS: Among adults residing in the United States, reported glaucoma is associated with an increased risk of all-cause and cardiovascular disease mortality. Associations between glaucoma and cancer were inconsistent and may reflect, in part, a detection bias, in which glaucoma is more likely to be diagnosed in adults receiving health care because of other medical conditions.  相似文献
