Association between onset and progression of myopia and body mass index in adults
Abstract
The study aim to analyze the emergence and progression of adults with myopia and associate it with BMI. A total of 199 subjects with myopia participated. In addition to BMI, two questions were asked: “When did your myopia appear?” and “Has your myopia decreased or increased over time?”. The difference between the groups (“< 24 kg/m2” and “> 24 kg/m2”) was analyzed using the Mann-Whitney test, and binomial logistic regression analyses were performed to assess the association between the variables, considering p<0.05 as significant. Of the participants with myopia [right eye: OR=1.75 (0.8; 2.75) degree; left eye: OR=1.75 (1; 2.75) degree], 65% were female, with a median age of 23 years. The right eye had a higher median for BMI > 24 kg/m2; and the left eye had an equal median, but without significance (p<0.4). Individuals who had myopia in the late phase [OR=1.91 (1.04; 3.53); p=0.03) and who presented an increase in myopia [OR=2.20 (1.14; 4.36); p=0.02] were more likely to have a BMI> 24 kg/m2. In this context, more research should be carried out with larger samples and longitudinal analysis, aiming to expand the information regarding this context.
