Overview

• Researchers assessed 1,005 Chinese children aged 6–8 from the population-based Hong Kong Children Eye Study using a 280-item food frequency questionnaire.
• Higher omega-3 intake was linked to shorter axial length and less myopic refraction after adjustments for age, sex, BMI, near work, outdoor time, and parental myopia.
• Children with the highest saturated fat intake showed the opposite pattern, and no other nutrients were associated with myopia measures.
• Outcomes and diet were based on parent-reported questionnaires, and the study did not include blood biomarkers to confirm nutrient levels.
• The authors note Hong Kong’s high myopia prevalence could limit broader applicability and call for confirmation in other populations.
