摘要
目的分析隆阳区妊娠期妇女不同孕期以及孕前体质量体成分的差异。方法对隆阳区妇幼保健院建立孕检档案接受孕期检查的10 913例孕妇采用多频生物电阻抗法测量其体成分。根据孕周分为孕早期组(5 616例)、孕中期组(4 396例)、孕晚期组(901例)3组;根据中国BMI参考标准,将孕前体质量指数分为消瘦组(2 490例)、正常体质量组(6 399例)、超重组(1 507例)、肥胖组(517例);按照怀孕时是否处于主要的生育年龄,将年龄分为<23岁组(3 757例)、23~28岁组(4 803例)、29~34岁组(1 830例)、≥35岁组(523例)4个年龄段,比较各组间体成分的差异。结果孕早期、中期、晚期3组体成分差异有统计学意义(P <0.05),体成分随孕期增加而增加;妊娠前体质量正常组、消瘦组、超重组和肥胖组各组的基础代谢率、总体水、细胞内液、体脂百分比、脂肪重、去脂体重、肌肉重比较差异有统计学意义(P <0.05),均随体重的增长而增加;4个年龄组,其中细胞内液、体脂百分比、脂肪重比较差异有统计学意义(P <0.05),且随着怀孕年龄的增加而增加。结论根据妊娠期妇女体成分的变化对其营养状况进行评价,并予合理的营养指导,为减少孕期并发症及不良妊娠结局的发生率提供临床与流行病学依据。
Objective To characterize the difference of body mass and body composition among women in pre-pregnancy period and different pregnant stages in Longyang District,Baoshan city.Methods The body composition of 10913 pregnant women were measured by multi-frequency biological resistance method.The subjects were divided into three groups based on gestational age:the early gestational group(5616 cases),the mid gestational group(4396 cases)and the late gestational group(901 cases);according to the Chinese BMI reference standard,based on the pre-pregnancy body mass index the subjects were divided into thin group(2490 cases),normal weight group(6399 cases),overweight group(1507 cases)and obesity group(517 cases).According to whether or not the subject is in the primary reproductive age,subjects were divided into 4 groups:<23 years old(3757 cases),23~28 years old(4803 cases),29~34 years old(1830 cases)and≥35 years old(523 cases).Body composition data were collected and compared between each group.Results The body composition of the three groups in early,middle and late pregnancy was statistically significant(P<0.05).There were statistically significant differences in basal metabolic rate,total water,intracellular fluid,body fat percentage,fat weight,lean body weight and muscle weight in the groups with normal weight group,thin group,overweight group and obesity group(P<0.05),all of which increased with the increase of body weight.Among the four age groups,the differences in intracellular fluid,percentage of body fat and fat weight were statistically significant(P<0.05)and increased with the increase of pregnancy age.Conclusion The nutritional status of pregnant women was evaluated according to the changes of body composition during pregnancy,and reasonable nutrition guidance was given to provide clinical and epidemiological basis for reducing the incidence of pregnancy complications and adverse pregnancy outcomes.
