Obesity Prevention Policy

Adults aged 30–49, who bear the highest obesity risk in both sexes, should be prioritized for early intervention. The study's findings support a differentiated, life-course approach to obesity prevention rather than a uniform policy response. Female obesity interventions should extend beyond socioeconomic levers to include physical activity access, reproductive health integration, and community outreach. Interventions targeting male obesity should address occupational sedentarism and dietary behaviours associated with higher socioeconomic status environments. Embedding obesity screening and management into routine healthcare for women, including around reproductive events, is recommended to reduce long-term risk.
