    Objective The objective was to determine the prevalence of iron deficiency and iron deficiency anemia among exclusively breastfed infants from one to six months of life and to identify associated risk factors. Methods This is a cohort study of the hemoglobin and serum ferritin levels of 102 healthy full-term infants, weighing more than 2500 grams (5.5 pounds) at birth, evaluated for growth development and supported to promote exclusive breastfeeding. Hemoglobin and ferritin levels were measured in the first, fourth, and sixth months of life. The hemoglobin and ferritin levels of the mothers were also measured in the first month postpartum. Results At four months, 5.7% presented iron deficiency and 3.4% had iron deficiency anemia. At six months, the percentage of children with iron deficiency increased more than four times, reaching 26.1%, while iron deficiency anemia was present in 23.9% of the infants studied. Iron deficiency at six months of age was significantly correlated to growth velocity. Conclusion According to the results of this study, exclusive breastfeeding protects infants from iron deficiency and iron deficiency anemia for the first four months of life. After this age, in accordance with the literature, the findings of this study demonstrated an increase in anemia and iron deficiency rates, adding to evidence that supports the monitoring of iron levels in exclusively breastfed children presenting higher weight gains beginning at four months of age.

    BACKGROUND: The motorized treadmill elicits stepping in infants, however the effects of belt speed on treadmill-elicited stepping patterns are still unknown. OBJECTIVE: To examine the effect of belt speed on treadmill-elicited infant stepping. METHODS: Six normally developing infants, aged between 11 and 13 months and acquiring independent walking, were videotaped while stepping on a treadmill at four belt speeds (0.1, 0.16, 0.22, and 0.28 m/s), with passive markers affixed to the major joints (shoulder, hip, knee, and ankle). The images were digitized and analyzed using the software programs Ariel Performance Analysis System, Matlab, and SPSS (Statistical Package for Social Sciences, v.10). The analyzed variables were the descriptive, temporal, coordinative, and angular characteristics of the treadmill-elicited steps at the four speeds. RESULTS: At 0.22 and 0.28 m/s, stride velocity and duration increased, and the duration of the stance phase decreased at 0.22 m/s. Moreover, at 0.22 and 0.28 m/s, the knee joint range of motion increased. CONCLUSIONS: The moderate and high speeds seem to be more appropriate to elicit stepping in infants who are acquiring independent walking, with 0.22 m/s being the speed that seemed the most appropriate.
