Expert Opinion: Sedentary Behaviour in Children Linked to Narrower Blood Vessels in the Eye
A study of children in Sydney suggests that retinal blood vessel narrowing increases with sedentary activity. Children who engaged in more physical activities, such as rugby or cricket, had wider retinal arterioles. The magnitude of vessel narrowing for each hour per day of sedentary behaviour was similar to a 10 mm of mercury rise in systolic blood pressure. Experts independent of the study respond to the research and what it means for children’s health.
