Abstract Purpose : This study was conducted to determine the effect of cataracts on quality of life in adults over 40 years of age using raw data from the 7th National Health and Nutrition Survey (2016-2018). Methods : We analyzed the relationship between gender, age, depression, and illness-related quality of life among 4,394 adults aged 40 years and older who responded to a diagnosis of cataract in the 7th National Health and Nutrition Examination Survey (2016-2018). Dichotomized variables were analyzed using the chi-square test (X2). Relationships between cataract, depression, and quality of life sub-variables were analyzed using logistic regression, adjusting for the effects of age and gender. A value of p<0.05 was considered significant. Results : In the logistic regression analysis results corrected for age and gender, cataracts were significantly related to cataracts in terms of motor ability (walking activity), pain and discomfort, anxiety and depression. In terms of restrictions on motor ability (walking activity), cataract disease patients were 1.37 times (95% CI: 1.14-1.65), pain and discomfort were 1.3 times (95% CI: 1.11-1.51), and anxiety and depressive symptoms were 1.38 times (95% CI: 1.10-3.75) at increased risk, confirming that cataracts significantly lowered the quality of life of the subjects. However, in terms of self-care (bath or dressing) and daily life, after correcting age and gender, a significant relationship with cataracts could not be confirmed. Conclusion : It was confirmed that cataracts affect exercise ability, pain/comfort, anxiety/ depression, etc., which can also reduce the quality of life.
