The ZANE Study (Estudo do Estado Nutricional e da Dieta em Raparigas Adolescentes na Zambézia) focuses on the nutrition of adolescent girls in Zambézia Province, Central Mozambique. Our aim was to study the food consumption, dietary intake and nutritional status among 15 to 18-year-old adolescent girls. Data was collected in 2010 during two seasons and in one city and two districts. . Our research questions include: What is the prevalence of stunting, thinness, overweight and deficiencies of vitamins and minerals? What are the main food sources of energy, protein and micronutrients in the diet? What is the fatty acid status of the girls? Are dietary patterns or dietary diversity scores associated with blood concentrations of vitamins and minerals? Are there differences in diet and nutritional status between urban and rural girls?
