Abstract:
Objective:To evaluate the intelligence, movement and physical development of 2-month-old infants, and to explore the influencing factors of early infant development.Methods:A total of 203 infants aged 42 days who underwent physical examination in the Department of Neonatology of the Fourth Affiliated Hospital of Harbin Medical University from May to December 2021 were selected as subjects. At the age of 2 months, 184 infants were followed up for their intelligence, movement and physical development. The intelligence and movement development of infants were evaluated with the intelligence development scale. Their body length, weight, and head circumference were measured, and physical development was assessed by Z-score method. Logistic regression was used to analyze the influencing factors of intelligence, movement and physical development of 2-month-old infants.Results:The median mental developmental index (MDI) of 184 2-month-old infants was 101; the median psychomotor developmental index (PDI) was 89; the body length was (59.3 ± 2.0) cm, the body weight was (5.8 ± 0.6) kg, and the head circumference was (38.9 ± 1.1) cm. Multiple logistic regression analysis showed that the influencing factors of MDI were maternal delivery age and infant gestational age [odds ratio ( OR) = 0.849, 0.463, P < 0.05]; the influencing factors of PDI were maternal prenatal education and average sleep time per night during pregnancy ( OR = 0.512, 0.666, P < 0.05); the influencing factor of body mass index (BMI) was maternal iodine supplements during pregnancy ( OR = 2.858, P = 0.018); the influencing factor of length-for-age Z-score (LAZ) was maternal prenatal education during pregnancy ( OR = 0.265, P = 0.026); the influencing factors of weight-for-age Z-score (WAZ) included maternal average sleep time per night, the frequency of sleeping time exceeding 12 am and the average weekly exercise duration during pregnancy ( OR = 0.277, 1.106, 0.990, P < 0.05). Conclusion:Maternal delivery age, prenatal education, sleep duration, intake of iodine supplements, exercise duration during pregnancy, and infant gestational age are factors affecting the intelligence, movement and physical development of 2-month-old infants, which should be paid attention to and measures should be taken to improve the population quality.
