There is evidence of overweight and micronutrient deficiencies in the same individuals. We examined the relationship between weight and iron status in non‐pregnant women of reproductive age using 2005 National Survey of the Nutrition Situation in Colombia (n= 3,390). Prevalence of overweight (13–17y: BMI‐age> 85%, 18–49y: BMI> 25.0 kg/m2), iron deficiency (ID, serum ferritin< 12.0 μg/L), and anemia (Hb< 12 g/dL) was 40.1%, 15.8% and 34.4%, respectively. Overweight with ID or anemia was 5.7% and 12.6%, respectively
