“…The prevalence of cataracts was higher in women (42.3%) than in men (38.9%), which is in line with previous studies, 11,12,19 and could be explained by the difference in environmental exposure, and the results of hormonal changes associated with menopause. 20 Moreover, we found that the association between low SES and the high proportion of cataracts was observed only in women.…”

“…8,14 Income or education levels were inversely related to the 10-year cumulative incidence of nuclear cataracts in the Beaver Dam Eye Study. 7 Similar trends were also observed in studies performed in Asian countries such as Singapore, 11,15 India, 12 China, 10 and Bangladesh. 16 The reason for the association between low SES and the prevalence of cataracts is yet to be elucidated, although several possible explanations have been suggested.…”

“…However, we did not examine the information about current and/or past fuel and stove use. Several studies from Western countries, 7,9,14,19,2 as well as Asian countries, [10][11][12]15 have demonstrated the positive relationship between cigarette smoking and the prevalence and/or progression of cataracts. Moreover, a dose-response relationship has been demonstrated between smoking and the prevalence of cataracts.…”

“…Moreover, a dose-response relationship has been demonstrated between smoking and the prevalence of cataracts. 11,12 Smoking could affect the lens and retina by promoting atherosclerosis of ocular capillaries and oxidative stress by reactive oxygen species generation. 23 We initially found that the crude prevalence of cataracts was higher in non-or ex-smokers than in current smokers in men (Table 2); however, after adjusting for age, current male smokers had an increased risk for nuclear cataracts (Table 3), which suggests a strong effect of age on cataracts.…”

“…However, these studies have been performed mainly in Western countries including the United States, European nations, and Australia. [7][8][9] Although there has been recent data from China and Southeast Asia, including India and Singapore, [10][11][12] the data of population-based trends from other Asian countries, including the East Asian countries, have not been fully reported.…”

Purpose Cataracts are the leading cause of visual impairment and blindness, and therefore early identification and modification of the risk factors for cataracts are meaningful. This study aimed to investigate the relationship between socioeconomic status (SES) and lifestyle factors, and age-related cataracts in South Korea. Methods This cross-sectional study was based on data collected in the 2008-2011 Korea National Health and Nutrition Examination Survey. A total of 15 866 subjects, aged ≥ 40 years, were included. SES was defined using household income and education level. Sociodemographic, lifestyle, and other associated factors were assessed by health interviews and examinations. Cataracts were diagnosed via slit-lamp examination using the Lens Opacities Classification System III. Results The prevalence of any cataract was 38.9% in men and 42.3% in women (Po0.001). In women, the risk of cataracts increased with decreases in household income (P-value for trend = 0.016 and 0.041 in any, and cortical cataract, respectively) and education level (P-value for trend = 0.009, 0.027, and 0.016 in any, nuclear, and cortical cataract, respectively) after adjusting for confounding factors. Current smoking was correlated with nuclear cataracts in men (OR 1.21; 95% CI: 1.00, 1.46 in age-adjusted analysis) and cataract surgery in women (OR 2.25; 95% CI: 1.00, 5.04 in multivariate-adjusted analysis). Conclusions Socioeconomic disparities in cataract prevalence were observed in women; current smoking increased the risk of nuclear cataracts in men and surgery in women.Public health interventions focusing on gender differences are warranted to prevent and treat cataracts.

Objective: To describe the relationship of smoking, sex, and socioeconomic factors with age-related cataract in Malay adults in Singapore. Methods: In a population-based study, 3280 Malay individuals aged 40 to 80 years participated (78.7% response rate). All had interviews, systemic examination, and laboratory investigations. Lens opacity was graded from slitlamp and retroillumination photographs using the Wisconsin Cataract Grading System. Smokingcataract associations were compared with the Blue Mountains Eye Study in Australia. Results: Of 2927 participants (89.2%) with gradable lens photographs, 1338 (45.7%) had cataract. After adjusting for age, sex, body mass index, hypertension, and diabetes, current smokers had a higher prevalence of nuclear cataract (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.46-2.98), cortical cataract (OR, 1.33; 95% CI, 1.02-1.74), posterior subcapsular cataract (OR, 1.39; 95% CI, 1.02-1.91), or any cataract (OR, 1.48; 95% CI, 1.10-1.99). These associations were not seen in the Blue Mountains Eye Study. Primary or lower education (OR, 1.67; 95% CI, 1.06-2.64) and low monthly income (OR, 1.43; 95% CI, 1.09-1.87) were both associated with nuclear cataract, while small-sized public housing was associated with posterior subcapsular cataract (OR, 1.70; 95% CI, 1.28-2.25). Among men, 43.5% currently smoked compared with only 3.2% of women. The population attributable risk of nuclear cataract due to smoking was estimated to be 17.6% in men. Conclusions: Smoking and indicators of low socioeconomic status were associated with cataract in Malay persons, with 1 in 6 nuclear cataract cases in men attributable to smoking. Smoking-cataract associations were stronger in Malay than in white persons.
