ABSTRACT
Objective:
To explore the effect of strengthening individualized nutrition education in the second trimester based on first trimester on blood glucose.Methods:
A retrospective study was conducted on 398 pregnant women aged (31.79±3.48) (23-41) years old who underwent an oral glucose tolerance test (OGTT) from October 2021 to December 2022 at Beijing Tsinghua Changgung Hospital. They were divided into two groups according to whether the women were re-visited in second trimester or not. The routine group consisted of 205 pregnant women aged between 24 and 41 (31.49±3.36) years old who only received the first trimester nutrition education and the strengthening group consisted of 193 pregnant women aged (31.92±3.97) (23-41) years old who received both the first and second trimester nutrition education. Then according to pre pregnancy body mass index (BMI), they were divided into normal (18.5 kg/m2≤BMI<24 kg/m2) and overweight (24 kg/m2≤BMI<28 kg/m2). The OGTT blood glucose level, the positive rate of gestational diabetes (GDM) and the weight gain during pregnancy were compared between the two groups with different BMI, in order to analyze the effect of strengthening nutrition education in the second trimester of pregnancy on blood glucose.Results:
The differences between the two groups were not statistically significant in terms of the pregnant women's age, proportion of pregnant women aged≥35, proportion of pre-pregnancy BMI and overweight, parity and early pregnancy blood glucose (all P>0.05). The blood glucose levels of OGTT at 0, 1, and 2 hour were (4.57±0.37), (8.41±1.70), and (7.28±1.51) mmol/L, respectively, lower than those in the routine group [(4.74±0.48), (9.44±1.55), and (8.27±1.58) mmol/L, respectively, all P<0.001]. The positive rate of GDM in the strengthening group was 35.23% (68/193), which was lower than that in the routine group (91.71%, 188/205) (P<0.001). After the BMI stratification, the OGTT blood glucose levels and the positive rate of GDM in the strengthening group were still lower than those in the routine group (all P<0.05). The weight gain with normal BMI in the early pregnancy in routine group was higher than that in the strengthening group (P=0.003), but there was no significant statistical difference in weight gain of overweight pregnant women at different gestational weeks (all P>0.05).Conclusion:
Strengthening a nutrition education about second trimester for pregnant women in the early stages of pregnancy can effectively improve blood glucose levels and reduce the positive rate of GDM.
