ABSTRACT

Objective: To determine the relationship between exclusive breastfeeding beyond six months until first year of age, and the increase of height. To determine the relationship between levels of hemoglobin, hematocrit and serum iron in mothers and new born with exclusive breastfeeding beyond six months and the increase of height at the first year of age. Methods: We follow up 80 healthy new born, 41 female (52%) and 39 male (48%), healthy mothers products, from born to the first twelve months of age. We determine levels of serum iron, hemoglobin and hematocrit in mothers before birth and in the new born at birth and six months of age, we measure weight, height and weight/height and compare this with NCHS/OMS references. We determine median an SD for weight, height and weight/height for age and gender, and made T test for analyze differences. Results: Of those 80 new born, seven (8.7%) were eliminated because not fulfill criteria. We did not find significant differences in mothers levels of hemoglobin (p = 0.50), hematocrit (p = 0.63) and serum iron (p = 0.21). We neither find significant differences in children at born levels of hemoglobin (p = 0.32), hematocrit (p = 0.60) and serum iron (p = 0.60). Without changes in this levels at six months, hemoglobin (p = 0.87), hematocrit (p = 0.62) and serum iron (p = 0.68). The percentiles for height at six months were 60.3 ± 28 for breastfeeding group and 59.2 ± 21 for bottle feeding group (p = 0.02). The percentiles for weight/height were 42.8 ± 22 for breastfeeding group and 32.3 ± 24 for bottle feeding group (p = 0.56).At 12 moths, height percentiles were 40.4 ± 25 for breastfeeding group and 49.3 ± 25 for bottle feeding group (p = 0.72). The percentiles weight/height at 12 months were 35.1 ± 22 for breastfeeding group and 25.2 ± 21 for bottle feeding group (p = 0.90). Conclusion: The present results can not conclude that exclusive breastfeeding beyond six months until 12 months of age, affect negatively the increase of height in the second semester of life.
