在过去几十年中，妇女超重和肥胖的流行率有所增加。这是一个严重的问题，因为受孕前的高BMI是许多妊娠不良结果的独立风险因素。因此，饮食咨询，旨在刺激体重减轻超重和肥胖妇女怀孕前最近已被推荐。然而，以减肥为目的的节食可能会给母亲和后代带来健康风险。我们进行了系统的文献综述，以确定研究怀孕前饮食干预对减肥效果的论文。本研究的目的是评估超重或肥胖女性受孕前体重减轻对母亲和后代健康相关结局的影响，使用2000年1月至2011年12月期间发表的研究。我们的第一次文献检索产生了486篇引文，根据预定义的合格标准，选择了58篇引文并全文排序。两名小组成员阅读每份论文。选择了15项研究进行质量评估，其中2项被认为适合纳入证据表。一项补充检索确定了168篇引文，其中4篇论文全文排序。这两项选定的研究提供了超重和肥胖妇女的数据。一项研究显示，孕前减肥对妊娠期糖尿病的风险有积极影响，另一项研究显示，BMI高于25的妇女在孕前减肥后，其大胎龄婴儿的风险降低。没有研究调查怀孕前饮食干预对减肥的影响。目前还缺乏对超重和肥胖妇女的研究，调查怀孕前饮食引起的体重减轻对母亲和后代健康相关变量的影响。这类研究可能缺乏，因为它们很难进行。因此，需要采取其他战略来控制女孩和育龄妇女的体重。
The prevalence of overweight and obesity in women has increased during the last decades. This is a serious concern since a high BMI before conception is an independent risk factor for many adverse outcomes of pregnancy. Therefore, dietary counseling, intended to stimulate weight loss in overweight and obese women prior to conception has recently been recommended. However, dieting with the purpose to lose weight may involve health risks for mother and offspring. We conducted a systematic literature review to identify papers investigating the effects of weight loss due to dietary interventions before conception. The objective of this study is to assess the effect of weight loss prior to conception in overweight or obese women on a number of health-related outcomes in mother and offspring using studies published between January 2000 and December 2011. Our first literature search produced 486 citations and, based on predefined eligibility criteria, 58 were selected and ordered in full text. Two group members read each paper. Fifteen studies were selected for quality assessment and two of them were considered appropriate for inclusion in evidence tables. A complementary search identified 168 citations with four papers being ordered in full text. The two selected studies provided data for overweight and obese women. One showed a positive effect of weight loss before pregnancy on the risk of gestational diabetes and one demonstrated a reduced risk for large-for-gestational-age infants in women with a BMI above 25 who lost weight before pregnancy. No study investigated the effect of weight loss due to a dietary intervention before conception. There is a lack of studies on overweight and obese women investigating the effect of dietary-induced weight loss prior to conception on health-related variables in mother and offspring. Such studies are probably lacking since they are difficult to conduct. Therefore, alternative strategies to control the body weight of girls and women of reproductive age are needed.
