Effect of age, sex, education, socioeconomic status, religion, level of visual impairment, and cause of visual impairment on noticing decrease in vision over the past 5 years and on seeking treatment by multiple logistic regression
| Odds ratio for noticing decrease in vision (95% CI) | Odds ratio for seeking treatment (95% CI) | |
|---|---|---|
| Age (years) | ||
| <60 | 1.00 (0.37–2.72) | 0.57 (0.30–1.10) |
| ⩾60 | 1.00 | 1.00 |
| Sex | ||
| Male | 1.00 | 1.00 |
| Female | 2.25 (0.85–5.92) | 1.55 (0.79–3.02) |
| Education | ||
| Literates | 1.00 | 1.00 |
| Illiterates | 1.69 (0.61–4.67) | 0.75 (0.37–1.50) |
| Socioeconomic status | ||
| Extreme lower, lower | 1.00 | 1.00 |
| Middle, upper | 1.03 (0.41–2.59) | 1.36 (0.72–2.57) |
| Religion | ||
| Hindu | 0.64 (0.26–1.54) | 0.53 (0.28–0.98) |
| Muslim | 1.00 | 1.00 |
| Level of visual impairment | ||
| <6/18–6/60 | 1.00 | 1.00 |
| <6/60 | 5.31 (0.67–42.06) | 1.15 (0.55–2.43) |
| Cause of visual impairment | ||
| Other than refractive error | 1.00 | 1.00 |
| Refractive error | 0.34 (0.12–0.93) | 0.57 (0.28–1.16) |
↵Categories for these variables combined to increase the power of analysis. Age groups <60 and ⩾60 years combined to assess differences between the non-elderly and elderly groups. Cataract and others combined because both had higher rates than refractive error.
