根据一项新的研究,在生育治疗前减肥并不能增加肥胖妇女生育的机会。

  美国的一项研究发现,与对照组相比,在生育治疗前减肥的肥胖妇女的健康活产率没有明显差异。

  1、该研究的主要作者,宾夕法尼亚州赫尔希市宾夕法尼亚州立医学院的理查德-莱格罗教授说:"尽管它偏离了目前的临床标准,但没有足够的证据建议患有肥胖症和不明原因的不孕症的妇女在受孕前应该减肥。"

  2、这项研究发表在《PLOS医学》上,招募了300多名年龄在18至40岁之间的妇女,她们至少有一年不明原因的不孕症,定期排卵,身体质量指数为30或以上。

  3、这些患者被随机分为两组。一组接受减肥计划,包括更多的体育活动、减少热量的饮食和抗肥胖药物。这导致平均体重下降了7%。对照组没有被鼓励减肥,但增加了他们的体育活动。

  4、这些变化持续了16周。在此期间没有自发受孕的患者接受了最多三个周期的卵巢刺激和宫腔内人工授精的生育治疗。在这个过程中,精子被直接引入子宫以提高受精成功率。

  尽管与对照组相比,减重组的活产结果没有增加,但一些健康指标得到了改善,如血压和腰围降低。

  作者小组解释说,这些发现建立在其他研究越来越多的证据之上,即在生育治疗前,肥胖或超重妇女的孕前减肥对提高活产率没有好处。

  英国不孕不育协会的负责人拉吉-马图尔博士没有参与这项研究,他告诉MailOnline:"这项研究鼓励我们研究计划进行IVF治疗的病人的结果,以及严格的BMI限制为30是否是NHS的一个选择。

  一项新的研究表明,在生育治疗前减轻体重并不会增加肥胖妇女生孩子的机会。

  美国的一项研究发现,在生育治疗前减肥的肥胖妇女的健康活产率与对照组相比,没有明显的差异。

  虽然该研究偏离了目前的临床护理标准,但根本没有足够的证据来建议患有肥胖症和不明原因不孕症的妇女在受孕前减轻体重,"领衔作者、宾夕法尼亚州立赫尔希医学院的Richard Legro教授说。

  The study, published in PLOS Medicine, recruited more than 300 women aged 18-40 years with at least one year of unexplained infertility and normal ovulation and a body mass index of 30 or higher. BMI was used as a screening tool to determine whether a person had a healthy weight relative to their height.

  Patients were randomized into two groups. One group was placed on a weight loss program that included increased physical activity, a calorie-restricted diet, and anti-obesity medications, which resulted in an average weight loss of 7%.

  These changes lasted for 16 weeks. Patients who did not conceive naturally during this period received up to three cycles of fertility treatment with ovarian stimulation and intrauterine insemination. This procedure involved delivering sperm directly into the uterus to improve fertilization success.

  While live birth success did not improve in the weight loss group compared to the control group, some health indicators did improve, such as lower blood pressure and reduced waist circumference.

  According to the authors, these findings build on evidence from other studies that preconception weight loss in obese or overweight women before receiving fertility treatment has no benefit in improving live birth rates.

  Dr Raj Mathur, head of the British Infertility Society, who was not involved in the study, told MailOnline: "This study does encourage us to look at the outcomes for patients planning IVF treatment and whether a hard BMI of 30 is justified for the sake of NHS eligibility.
