Chinese Journal of School Health 2022;43(7):1090-1094
Objective:
To explore the relationship between prepregnancy body mass index, weight gain during pregnancy with preschool obesity and body composition in offspring, so as to provide evidence for gestational weight gain and childhood obesity prevention.
Methods:
A total of 1 333 preschool children were recruited from 3 kindergartens in Tianjin from September to December 2020. Structured questionnaire was used to collect children s lifestyle information. Height, weight and body fat mass of children were assessed, and body fat percentage (FM%), fat mass index (FMI) and non fat mass index (FFMI) were calculated. Maternal medical records were collected and the mothers were grouped according to their prepregnancy weight status and weight gain during pregnancy. χ 2 test, t test, linear regression model and Logistic regression were used to analyze the differences of obesity and body composition among different groups.
Results:
The prevalence of overweight and obesity in preschoolers was 12.7% and 7.7%. After adjusting maternal age and delivery, gestational age, gender, age and lifestyle of children, the correlation between maternal pre pregnancy BMI,gestational weight gain with obesity and body composition indexes of children in preschool age was statistically significant ( P <0.05). For mothers with normal weight before pregnancy, excessive weight gain during pregnancy increased risk of high FM% and high FMI in offspring ( OR=1.81, 1.68, P <0.05). There was no significant correlation between maternal weight gain during pregnancy with offspring obesity and body composition among mothers with prepregnant overweight or obesity.
Conclusion
Maternal weight status before pregnancy and weight gain during pregnancy are correlated with obesity and body composition in the preschool age of offspring. It is suggested that mothers should maintain appropriate weight status before and during pregnancy.
