The association between body mass index and age related cataract.

This study was carried out to determine the association between body mass index and age related cataract among patients attending eye clinic. We conducted a case control study. The outcome of clinical eye assessment determined the patient's status. Mean body mass index among the cases was shown to be higher (25.4 +/- 4.5) than the control group (24.4 +/- 3.9) (p < 0.01). Crude analysis showed that only obese respondents were 2.4 times more likely to develop age related cataract, however this association was not seen in the multivariate analysis after adjusting for other determinants (aOR 1.81; 95% CI 0.91 - 3.62). We conclude that there is no association between body mass index and age related cataract.
