Nutritional assessment in relation to breastfeeding and current protein intake in schoolchildren from indigenous communities of Ecuador.
OBJECTIVES: Stunting is highly prevalent in indigenous communities and may be associated with nutritional deficits; however, scientific evidence is limited. Thus, we studied the nutritional status of indigenous schoolchildren from Licán, Riobamba, Ecuador, and its relationship to breastfeeding history and current protein intake. METHODS: A descriptive cross-sectional study including 81 children (5-9 years) was conducted. Nutritional status (weight, height and body mass index (BMI); assessed using Anthro Plus software), exclusive breastfeeding duration and weaning age (applying a questionnaire), and daily protein intake (analyzing the amount of food and preparations consumed; 24-hour recall) were evaluated. RESULTS: 23.5% of the schoolchildren presented stunting, and 18.5% had excess weight. Children exclusively breastfed for 7-11 months had a greater height (117.0 ± 0.61m versus 114.9 ± 0.72m, P = 0.047) and height/age Z-score (-0.8 ± 1.1 versus -1.5 ± 0.9, P = 0.039) than those breastfed for ≥12mo. Weaning age had a direct relation to weight (r = 0.247, P = 0.027) and BMI (r = 0.308, P = 0.005). Both BMI [16.96kg/m2 (tercile 3, T3) versus 15.42kg/m2 (T1), P = 0.035] and BMI/age Z-score [0.69 (T3) versus -0.20 (T1), P = 0.041] were greater in children weaned at ≥19mo. An indirect relation was found between daily protein intake per body weight and height (r = -0.315, P = 0.004), and BMI (r = -0.322, P = 0.003). Children with stunting consumed greater amounts of protein/kg/day [χ2(2) = 6.739, P = 0.034; t-test: 2.6 ± 0.7 versus 2.02 ± 0.84g/kg/day, P = 0.038], while their BMI and BMI/age Z-score were lower (P < 0.001). CONCLUSIONS: Breastfeeding history and current protein intake of schoolchildren from Lican indigenous communities were associated with nutritional status; however, further studies are needed to confirm these findings.
