Abstract
BACKGROUND: Anemia in infants and young children can have long-term effects on cognitive and physical development. In Ma'anshan City, China, there has been growing concern about the prevalence of anemia among children aged 6 to 36 mo. Understanding the factors influencing this condition is crucial for targeted interventions and improving overall child health in the region. AIM: To analyze the anemia status and influencing factors of infants and young children aged 6 to 36 mo in Ma'anshan City, China. Providing scientific evidence for reducing the incidence of anemia and improving the health level of children in this age group. METHODS: The study encompassed 37698 infants and young children, aged from 6 to 36 mo, who underwent health examinations at the Ma'anshan Maternal and Child Health Hospital from January 2018 to October 2022 were included in the study. Basic information, physical examination, and hemoglobin detection data were collected. Descriptive analysis was used to analyze the prevalence of anemia in children in the region, and univariate analysis was used to analyze the influencing factors of anemia. RESULTS: The mean hemoglobin level of infants and young children aged 9 to 36 mo increased with age, and the anemia detection rate decreased with age. The anemia detection rate in rural infants aged 6, 9, and 12 mo was higher than that in urban infants. Although the anemia detection rate was higher in 6-mo-old boys than girls, it was higher in 24-mo-old girls than boys. There were statistically significant differences in the anemia detection rates among 9-mo-old and 12-mo-old infants with different nutritional statuses (emaciation, overweight, obese, and normal). Moreover, there were no statistically significant differences in anemia detection rates among infants and young children with different nutritional statuses at other ages. Besides, the anemia detection rates in obese infants aged 9 and 12 mo were higher than those in normal and overweight infants, with statistically significant differences. Finally, there were no statistically significant differences in the anemia detection rates between emaciation infants and those with other nutritional statuses. CONCLUSION: The anemia situation among infants and young children aged 6 to 36 mo in Ma'anshan City, China, is relatively prominent and influenced by various factors. Our result shown that attention should be paid to the anemic infant and young child population, with strengthened education and targeted prevention and dietary guidance to help them establish good living habits, improve nutritional status, and reduce the occurrence of anemia to improve children's health levels.
