Urban living linked to slightly healthier diets but also higher overweight and obesity among adolescents in Viet Nam

Key takeaways • Adolescents living in urban areas of Viet Nam face a complex mix of diet challenges , a recent study shows. • Urban adolescents face higher overnutrition risks. Overweight and obesity were nearly three times more common in urban than rural areas. • Adolescent diets were slightly healthier in urban than in rural areas. Urban adolescents ate more healthy foods but also consumed more unhealthy foods.

Agricultural inputs and harvest among vegetable producers in rural Sri Lanka: Insights from a baseline survey of the Fruit and Vegetables for Sustainable Healthy Diets (FRESH) end-to-end evaluation

Sri Lanka’s agricultural sector plays a vital role in the food security and nutrition of its people. In recent years, overlapping crises, including the COVID-19 pandemic, severe economic collapse, climate-related shocks, such as cyclone Ditwah and subsequent flooding, and global political unrest have disrupted food systems and exacerbated food insecurity for Sri Lankans. These challenges have constrained access to nutrient-rich foods, while increasing reliance on cheaper, less nutritious alternatives. At the same time, Sri Lanka has been undergoing a nutrition transition characterized by increased consumption of ultra-processed foods and a double burden of malnutrition including micronutrient deficiencies and rising rates of overweight and obesity.
