Objective To investigate the difference in physical development,anemia and diet of infants and young children at different altitudes in Rikaze,and to explore the effect of altitude on their nutritional status. Methods The study coverd infants and young children who participated in health check-up in 9 countries in Rikaze.Physical development indexes and hemoglobin were collected.A self-designed questionnaire was used to investigate their diet. Results The sample consisted of 285 infants and young children.Infants and young children at 4 000 m below had no underweight,but there was a certain proportion of growth retardation;the incidences of underweight and growth retardation in infants and young children at 4 000 m above were significantly higher (χ2=32.323,P<0.001).The incidence of anemia was high,and increased with altitude (χ2=19.369,P<0.001).The breast-feeding rate was 66.7% in Rikaze,however,44.6% of infants and young children added complementary foods before 4 months old. Conclusions The malnutrition of infants and young children at high altitude is more serious.The incidence of anemia in infants and young children in Rikaze is high,and increases with altitude.The breast-feeding rate is high in Rikaze,but the complementary foods is too early.
