Objective: Stunting is a chronic condition reflecting poor nutrition and health. Our aim was to ascertain major predictors of stunting in children ,5 years old in Libya. (OR 5 0?53, 95 % CI 0?32, 0?90) and water storage (OR 5 0?70, 95 % CI 0?54, 0?90). These variables only explained 20 % of cases of stunting. Conclusion: Various multilevel actions are needed to improve nutritional status of under-fives in Libya. At risk-groups include those with young age (1-3 years), resident of Al-Akhdar region, boys, father's low educational level, poor psychosocial stimulation, poor housing environment, diarrhoea and low birth weight.
