ABSTRACT

[Objective]To investigate the influence of different pre-pregnancy body mass index(BMI)on blood glucose and serum lipid and pregnancy outcome during pregnancy.[Methods]Clinical records of 1115 singleton pregnant women who underwent obstetric examination and delivered in the first affiliated hospital of Sun Yat-sen University between January 1,2013 and December 31,2013 were collected. The patients were divided into 3 groups based on pre-pregnancy BMI,underweight(G1)BMI 0.05). By Pearson analysis,TG had significantly positive relationship with pre-pregnancy BMI(P < 0.05),but TC,LDL-C, HDL-C had negative relationship with pre-pregnancy BMI(P<0.05).(4)With the increase of pre-pregnancy BMI,the weight and head circumference of the newborn was gradually rising(P < 0.05). The average weight of the newborn among groups were(3.03 ± 0.42),(3.18 ± 0.45),(3.30 ± 0.46)kg,the head circumference were(32.98 ± 1.59),(33.43 ± 1.64),(33.87 ± 1.60)cm,there was statistical difference among groups(P<0.05). The shoulder circumference of the newborn of G1 was obviously lower than that of G2 and G3 group(P<0.05). Pearson analysis showed that the weight,body length,head circumference,shoulder circumference of the newborn had positive relationship with pre-pregnancy BMI(P < 0.05).[Conclusion]With the increase of pre-pregnancy BMI, the blood glucose at each time point,serum lipid and growth index of the newborn was gradually rising. We suggest that overweight and obese women should lose weight before pregnancy.
