孕前体重增长指数对孕期并发症及妊娠结局的影响

将180例孕妇按孕期体重增长情况分为ΔBMI增长较小组(A组,36例)、ΔBMI增长适中组(B组,104例),ΔBMI增长较大组(C组,40例),比较分析A、B、C三组妊娠期并发症及妊娠结局差异。结果 A组的低体重儿、高危新生儿发生率明显显著高于B组(P0.05),C组的GIGT、GDM、PIH、剖宫产、巨大儿、高危新生儿发生率显著高于B组(P0.05)。C组的GIGT、GDM、PIH、剖宫产、巨大儿发生率显著高于A组(P0.05),而C组的低体重儿发生率要显著低于A组(P0.05)。妊娠期体重增长指数过大或过小均会增加并发症的发生,导致不良妊娠结局,合理控制妊娠期体重增加有利于孕妇和胎儿孕产期安全,减少并发症和不良妊娠的发生。

试管助孕女性孕前体重指数及孕期体重增加与不良妊娠结局的关联性研究

目的研究我院试管助孕女性孕前体重指数和妊娠不良结局之间的关系研究。方法选取于2014年5月到2017年6月在我院进行试管助孕前体检并分娩的产妇,并同时其男方精液检查正常,助孕成功的女性患者的检查结果全部是单胎,且全部登记详细的病史资料及体检资料。主要的调查内容有:患者的妊娠年龄、生育史、怀孕周期、孕前体重指数、既往病史资料、是否有家族遗传病史、是否吸烟饮酒和是否有代谢性质的疾病,例如:高血压、高血脂、糖尿病等。并在调查过程中连续记录孕期妇女体重变化的情况,并且在调查对象分娩后随访妊娠结局。结果在3年的调查过程中,完善孕妇资料并且随访到妊娠结束的总共有3805人,调查对象的平均年龄是(29.15±3.26)岁,怀孕前体重指数的平均值是(21.23±2.03),孕妇在怀孕期间体重平均的增长数值大约是(14.13±4.65)kg,并且孕妇的怀孕周期越长,其体重指数以及体重全都有增长(P0.01),具有统计学上的意义。所有的调查对象之中,有800人体重指数低于18.5,体重指数大于18.5小于24的共有2212人,体重指数大于24的有793人。孕前超重和肥胖组的调查对象孕期体重增加最多。体重指数异常者(低体重、超重或肥胖者),不良妊娠发生率均增高,且显著高于正常体重者(P0.05)。结论女性孕前体重指数的异常值与不良妊娠的结局发生有着密切相关,是多种疾病的危险因素,且孕妇怀孕期间体重的增长与其孕前体重指数有着不可分割的联系。

孕前体质量指数与妊娠不良结局的相关性研究

目的探讨孕前体质量指数(BMI)与妊娠不良结局相关性。方法收集4 614例分娩的孕妇临床资料,根据孕前BMI不同将其分为低体质量组、正常体质量组、超重组和肥胖组,比较各组的子痫前期、妊娠期糖尿病、剖宫产、新生儿死亡、妊娠高血压、巨大胎儿、胎膜早破、耐糖量异常、产后出血等妊娠不良结局的发病率。结果低体质量组占13.5%,正常体质量组占70.5%,超重组占13.4%和肥胖组占2.6%。随着孕前BMI的增大,妊娠期的不良结局的风险也越来越大。除新生儿死亡以外,在其他妊娠不良结局中超重组和肥胖组的发病率要明显要高于正常体质量组,差异具有统计学意义(P0.05)。低体质量组的产后出血、耐糖量异常、新生儿死亡、剖宫产、妊娠期糖尿病的发病率与正常体质量组相比无明显的差异(P0.05),而子痫前期、妊娠高血压、巨大胎儿、胎膜早破的发生率明显低于正常体质量组,差异具有统计学意义(P0.05)。结论孕妇的孕前BMI对妊娠不良结局有较大的影响,加强对孕妇的孕前BMI控制,可以减少母婴并发症。

The impact of body mass index and weight gain during pregnancy on puerperal complications after spontaneous vaginal delivery.

BACKGROUND: We studied the effect of the prepregnancy body mass index (BMI) and weight gain during pregnancy on the rate of puerperal complications after spontaneous vaginal delivery. METHODS: This is a prospective cohort study of 11,114 women delivered spontaneously between 36 and 43 week's gestation at a university hospital, between January 1996 and December 2000. Postpartum complications were analyzed according to prepregnancy BMI category (low < 19.8; normal 19.8-26; high 26.1-29; obese > 29) and weight gain during pregnancy. Weight gain was defined as low, normal or high according to the National Academy of Science recommendations for BMI. RESULTS: Overall, 7.3% women had complications. Anemia and readmission were significantly more common in lean women than in women with normal BMI (3.5% versus 2.6%; P = .021 and 1.0% versus 0.3%; P < .001, respectively). Obese women had significantly more infectious complications (especially urinary tract infection) than women with normal BMI (6.3% versus 3.8%; P = .005). CONCLUSIONS: These results suggest that obese women should be screened for puerperal urinary tract infection. Weight gain during pregnancy has no influence on puerperal complications.     

初产妇早孕期增加的体质量指数对妊娠结局的影响

目的 探讨初产妇增加的体质量指数(BMI)与不良妊娠结局的关系.方法 回顾性的分析2011年4～12月在镇江市妇幼保健院分娩的有记录的单胎初产妇资料,根据第1次产前检查(妊娠10～15周)记录的体质量、身高计算BMI,分为4组(体质量较轻组BMI≤18、正常体质量组BMI＞18～24、过重体质量组BMI＞ 24～28、肥胖组BMI＞28),将其他3组的资料与正常体质量组资料相比较,分析早孕期BMI与妊娠结局的关系.结果 随BMI增加剖宫产率升高;过重体质量组的延期妊娠、引产风险与正常组相比增加RR ＝2.2(CI ＝1.4～3.4)、RR ＝2.3(CI=1.4～3.8);与其余3组相比正常体质量组的早产率6.8％最低.肥胖组的巨大儿风险与正常BMI组比较增加2.7倍RR ＝2.7(95％ CI ＝1.5～5.1),肥胖组的高危妊娠风险与正常体质量组相比增加2.1倍RR ＝2.1(CI ＝1.2～3.5).结论 增加的早孕期BMI与一些不良的妊娠结局相关.     

Maternal prepregnant body mass index and weight gain related to low birth weight in South Carolina

OBJECTIVES: The primary purpose of this study was to describe the proportion of low birth weight that could be potentially prevented by programs focusing on maternal prepregnant body mass index (BMI) and/or weight gain during pregnancy. METHODS: In this historic cohort design, study data consisted of birth certificates linked to the Pregnancy Risk Assessment Monitoring System for South Carolina resident women delivering in South Carolina during 1998 and 1999. Statistical analysis was conducted with the use of chi2, population-attributable risk, and logistic regression. The analysis was performed using SUDAAN to accommodate the analysis weight and extrapolate the sample data to the South Carolina state population. RESULTS: Eight percent of the very low birth weight (VLBW) rate in South Carolina can be attributed to inadequate weight gain in pregnancy. Approximately 19% of the state's VLBW rate can be attributed to either underweight or overweight BMI at conception. Women with less than adequate weight gain were 1.4 times more likely to deliver a VLBW baby and 1.9 times more likely to deliver a moderately low birth weight baby as compared with women with adequate weight gain. CONCLUSIONS: Appropriate maternal BMI at conception followed by adequate weight gain during pregnancy may have a substantial influence on reducing the number of low birth weight deliveries.     

Headache prevention outcome and body mass index

A population-based longitudinal study suggests that obesity is a strong risk factor for the development of headaches on 15 or more days per month. Little is know about the influence of weight on the response to headache preventive treatment. Herein we prospectively assessed the influence of the baseline body mass index (BMI) on the response to headache preventive treatment. We included adults with episodic or chronic migraine (ICHD-2), or transformed migraine (Silberstein and Lipton criteria) that sought care in a headache clinic. BMI was assessed in the first visit. Baseline information included headache frequency, number of days with severe headache (prospectively obtained over 1 month), and headache-related disability (HIT-6). The same information was obtained after 3 months of preventive treatment. Subjects were categorized based on BMI in: normal weight (/=30). We contrasted the headache end-points using anova with post-test and Kruskal-Wallis with post-test. We used logistic regression to model BMI and headache parameters adjusting for covariates. Our sample consisted of 176 subjects (79.5% women, mean of 44.4 years). At baseline 40.9% had normal weight, 29.5% were overweight and 27.3% were obese. No significant differences were observed in the number of headache days at baseline. After treatment, frequency declined in the entire population, but no significant differences were found by BMI group. Regarding the number of days with severe pain per month, there were also no significant differences at baseline (normal = 6.1, overweight = 6.5, obese = 6.7), and improvement overall (P = 0.01). However, changes were greater in the obese (reduction in 2.7 days with treatment) and overweight (3.9) vs. normal (1.5, P < 0.01). Finally, HIT scores at baseline did not differ by BMI group (normal weight = 63.8, overweight = 64.1, obese = 63.6). However, compared with the normal weighted group, change in HIT scores (follow-up baseline) were greater in the obese (6.4 vs. 3.5, P < 0.05) and overweight groups (6.8 vs. 3.5, P < 0.05). In the logistic regression model, BMI did not account for changes in disability, headache frequency, or in the number of days with severe headache per month, after adjusting for covariates. Contrary to what we hypothesized, obesity at baseline does not seem to be related to follow-up refractoriness to preventive treatment.
