To determine whether the prescription and follow-up of a behavioral program (customized nutritional advices and a constant physical activity) influences the occurrence of unfavorable maternal/neonatal outcomes among overweight/obese women.
A case-control study (1:3) included single pregnant women with Body Mass Index (BMI) ≥25 kg/m2, enrolled at 1st trimester. Cases (N.=95) were prescribed (by both the dietitian and gynecologist) a low-glycemic-index diet with an average intake of 1700/1800 kcal/day plus 30 minutes of walking at least 3 times/week (with four follow-up visits until delivery). Controls (N.=275) received a nutritional booklet about a healthy lifestyle, then attended their scheduled visits until delivery by the obstetricians in charge.
Gestational weight gain was similar between groups, despite obese women were higher in cases (67.4%) than in controls (54.5%, P=0.029). The occurrence of gestational diabetes mellitus (GDM) was lower in cases (21.5%) than in controls (32.7%; P=0.041). Such reduction remained related with the group of intervention (P=0.004) after correcting for confounders (BMI≥30 kg/m2, a family history of diabetes, age ≥35 and ethnicity). A higher number of controls developed pregnancy induced hypertension (PIH) (11.6% vs. 1.1% in cases, P<0.001). Preterm birth (PTB) occurred in one case and in 28 controls (10.2%; P=0.004). In half of them, PTB was spontaneous while medically indicated for intrauterine growth restriction, hemorrhage, PIH, GDM/macrosomia, Rh isoimmunization in the remnant.
An early behavioral intervention among overweight/obese pregnant women reduces unfavorable pregnancy outcomes.
确定一项行为计划(定制营养建议和持续体育活动)的处方及随访是否会影响超重/肥胖女性不良母婴结局的发生情况。
一项病例对照研究(1:3)纳入了孕早期体重指数(BMI)≥25 kg/m²的单胎孕妇。病例组(N = 95)由营养师和妇科医生共同开具低升糖指数饮食处方,平均每日摄入量为1700/1800千卡,外加每周至少3次、每次30分钟的步行(直至分娩进行4次随访)。对照组(N = 275)收到一本关于健康生活方式的营养手册,然后由负责的产科医生安排定期产检直至分娩。
两组间孕期体重增加情况相似,尽管肥胖女性在病例组中的比例(67.4%)高于对照组(54.5%,P = 0.029)。病例组妊娠期糖尿病(GDM)的发生率(21.5%)低于对照组(32.7%;P = 0.041)。在校正混杂因素(BMI≥30 kg/m²、糖尿病家族史、年龄≥35岁和种族)后,这种降低仍与干预组相关(P = 0.004)。更多对照组孕妇发生了妊娠高血压综合征(PIH)(病例组为1.1%,对照组为11.6%,P < 0.001)。1例病例和28例对照组孕妇发生了早产(PTB)(10.2%;P = 0.004)。其中一半早产为自发性早产,其余因胎儿宫内生长受限、出血、PIH、GDM/巨大儿、Rh血型不合免疫等医学指征导致早产。
超重/肥胖孕妇早期进行行为干预可减少不良妊娠结局。
