Риск латентного железодефицита, но не ЖД анемии, у детей возрастает при более длительном грудном вскармливании: железодефицит был в 1.7 раз чаще у детей, у которых грудное вскармливание было более 12 месяцев, по сравнению с теми, у кого грудное вскармливание было менее года, подробнее:
Included were 1647 healthy children (median age 36 months) with survey, anthropometric, and laboratory data. An association was found between increasing duration of breastfeeding and lower serum ferritin (P = .0015). Adjusted logistic regression analysis revealed the odds of iron deficiency increased by 4.8% (95% confidence interval: 2%-8%) for each additional month of breastfeeding. Exploratory analysis suggested an increasing cumulative probability of iron deficiency with longer total breastfeeding duration with an adjusted odds ratio of 1.71 (95% confidence interval: 1.05-2.79) for iron deficiency in children breastfed over versus under 12 months of age. The relationship between total breastfeeding duration and iron deficiency anemia did not meet statistical significance.
