Why has there been a deterioration in eyesight and an increase in weight among schoolchildren in Hong Kong?

-

The increasing prevalence of myopia, astigmatism, and hyperopia among schoolchildren in Hong Kong, as well as the observed deterioration in eyesight and an increase in weight, can be attributed to various interconnected factors affecting the health and well-being of this population.

Firstly, the pervasive use of digital devices, both for educational and recreational purposes, exposes children to prolonged screen time, which can contribute to visual strain and the development or progression of refractive errors such as myopia. The shift towards a more sedentary lifestyle, characterized by reduced outdoor activities and increased near work activities, may further exacerbate visual health issues among schoolchildren.


Moreover, dietary patterns and nutritional choices play a crucial role in determining weight-related outcomes among children. The consumption of energy-dense, processed foods high in sugar, salt, and fat, coupled with a decrease in physical activity levels, can lead to weight gain and associated health complications. The interplay between dietary habits, physical inactivity, and genetic factors may contribute to the observed increase in weight among schoolchildren in Hong Kong.


Additionally, the competitive academic environment and emphasis on academic excellence may inadvertently promote behaviors that are detrimental to both visual and overall health. Extended study hours, limited breaks, and inadequate outdoor playtime may contribute to visual fatigue, reduced eye health, and weight gain due to the lack of physical activity.


Furthermore, environmental factors, including limited access to recreational spaces, air pollution, and urbanization, may also influence the health outcomes of schoolchildren in Hong Kong. The combination of these factors creates a complex health landscape, where visual health and weight-related issues are intertwined and influenced by various societal, behavioral, and environmental determinants.

In conclusion, the observed deterioration in eyesight and an increase in weight among schoolchildren in Hong Kong can be understood within the broader context of lifestyle changes, environmental influences, and specific health trends affecting the pediatric population. Addressing these multifaceted challenges requires a comprehensive approach, encompassing education, policy interventions, community engagement, and promoting healthy lifestyle choices to ensure the well-being of schoolchildren in Hong Kong.
