Refractive error, physical activity, obesity

Behavior

a. Ocular intervention • School-based assessment of vision by & automatic refraction with cycloplegic refinement by study optometrist at school • Opportunity for child to make a choice of frames • Classroom-based educational intervention - on the meaning of myopia, benefits of spectacle wear, correction of common mis-conceptions about glasses • Provision of parental information sheet • Home visit by ¡§Vision Entrepreneurs¡¨ b. Ocular intervention ¡§plus¡¨¡XAbove plus health education interventions on: • Diet, obesity and weight control • Smoking c. Control • School-based assessment of vision by & automatic refraction with cycloplegic refinement by study optometrist at school

A. Vision-related: - at 6 months and 1 year post visit to schools • Prevalence of refractive error and need for spectacles • Proportion of children requiring refractive correction who have obtained it at baseline • Determinants of glasses wear at baseline • Behaviorial and familial risk factors for myopia • Visual function and healthy behaviour knowledge pre and post-intervention, compared to control schools • Uptake of spectacles among children with refractive error, comparing the control and ocular interventions • Other determinants of spectacle uptake • Impact of spectacle uptake on visual function and school performance outcomes • Barriers to parents in providing glasses

B. Outcomes related to other proposed health interventions ¡V at 6 months and 1 year post visit to schools • Changes in attitude/behaviour post-intervention, compared to control schools • Smoking rates and changes in attitude/behaviour post-intervention, compared to control schools • Social marketing approaches will be tested out and assessed for their impact
