Abstract:
Objective:To explore the relationship between the maternal dietary patterns during pregnancy and the early childhood BMI change trajectory.Methods:The subjects were 1 241 pairs of pregnant women and their children in Ma'anshan maternal and infant health cohort. The food frequency questionnaire was used to collect the maternal diet data during pregnancy. The cohort children were followed up at birth, month 3, 6, 12, 18 and 24, respectively. The body height and weight data of the cohort children were collected. The principal component analysis was used to determine the categories of maternal dietary patterns during pregnancy, group-based multi-trajectory modeling was used to fit the early childhood BMI change trajectory, and the multiple classification logistic regression model was used to evaluate the relationship between the maternal dietary patterns during pregnancy and the early childhood BMI change trajectory.Results:The maternal dietary patterns during pregnancy included protein type, healthy type, vegetarian type, processing type and beverage type, which could explain 50.04% of the total dietary variation. Among them, the protein type, main dietary pattern, could explain 21.34% of the total dietary variation. The early childhood BMI change trajectory was from thinnish stature to average stature, then to mild obesity, accounting for 42.9%, 45.6% and 11.5% respectively. After controlling the potential confounding factors, it was found that there was a statistical correlation between healthy type and beverage type of maternal dietary patterns during pregnancy and early childhood BMI change trajectory ( P<0.05). Comparison of change trajectories between thinnish type and average stature type, children in the low-level group of healthy diet pattern tended to have a thinnish type change trajectory in early life ( OR=1.286, 95% CI: 1.002-1.651). Comparison of change trajectories between mild obesity type and average stature type, children in the high-level group of beverage diet pattern tended to have a mild obesity type change trajectory in early life ( OR=0.565, 95% CI: 0.342-0.935). The other dietary patterns had no statistical correlation with the early childhood BMI change trajectory. Conclusions:Maternal dietary patterns during pregnancy can affect the early childhood BMI change trajectory, and the low-level healthy type diet is an independent risk factor for thinnish type change trajectory, and the high-level beverage type diet is an independent risk factor for the mild obesity type change trajectory.
