BACKGROUND AND AIM Inconsistencies exist with regard to the influence of dehydroepiandrosterone (DHEA) supplementation on insulin-like growth factor 1 (IGF-1) levels. The inconsistencies could be attributed to several factors, such as dosage, gender, and duration of intervention, among others. To address these inconsistencies, we conducted a systematic review and meta-analysis to combine findings from randomized controlled trials (RCTs) on this topic. METHODS Electronic databases (Scopus, PubMed/Medline, Web of Science, Embase and Google Scholar) were searched for relevant literature published up to February 2020. RESULTS Twenty-four qualified trials were included in this meta-analysis. It was found that serum IGF-1 levels were significantly increased in the DHEA group compared to the control (weighted mean differences (WMD): 16.36 ng/ml, 95% CI: 8.99, 23.74; p = .000). Subgroup analysis revealed that a statistically significant increase in serum IGF-1 levels was found only in women (WMD: 23.30 ng/ml, 95% CI: 13.75, 32.87); in participants who supplemented 50 mg/d DHEA (WMD: 15.75 ng/ml, 95% CI: 7.61, 23.89); in participants undergoing DHEA intervention for >12 weeks (WMD: 17.2 ng/ml, 95% CI: 8.02, 26.22); in participants without an underlying comorbidity (WMD: 19.11 ng/ml, 95% CI: 10.69, 27.53); and in participants over the age of 60 years (WMD: 19.79 ng/ml, 95% CI: 9.86, 29.72). CONCLUSION DHEA supplementation may increase serum IGF-I levels especially in women and older subjects. However, further studies are warranted before DHEA can be recommended for clinical use.

补充脱氢表雄酮(DHEA)对血清胰岛素样生长因子1(IGF-1)水平的影响:一项随机对照试验的剂量反应荟萃分析。

背景与目的关于补充脱氢表雄酮(DHEA)对胰岛素样生长因子1(IGF-1)水平的影响存在矛盾。不一致可以归因于几个因素,例如剂量,性别和干预时间等。为了解决这些矛盾之处,我们进行了系统的回顾和荟萃分析,以结合该主题的随机对照试验(RCT)的发现。方法在电子数据库(Scopus,PubMed / Medline,Web of Science,Embase和Google Scholar)中进行搜索,以检索截至2020年2月的相关文献。结果本荟萃分析包括24项合格试验。发现与对照组相比,DHEA组的血清IGF-1水平显着增加(加权平均差异(WMD):16.36 ng / ml,95%CI:8.99,23.74; p = .000)。亚组分析显示,仅女性中血清IGF-1水平有统计学上的显着提高(WMD:23.30 ng / ml,95%CI:13.75,32.87);在补充了50 mg / d DHEA(WMD:15.75 ng / ml,95%CI:7.61,23.89)的参与者中; 在接受DHEA干预> 12周的参与者中(WMD:17.2 ng / ml,95%CI:8.02,26.22); 在没有潜在合并症的参与者中(WMD:19.11 ng / ml,95%CI:10.69,27.53); 以及60岁以上的参与者(WMD:19.79 ng / ml,95%CI:9.86,29.72)。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。亚组分析显示,仅女性中血清IGF-1水平有统计学上的显着提高(WMD:23.30 ng / ml,95%CI:13.75,32.87);在补充了50 mg / d DHEA(WMD:15.75 ng / ml,95%CI:7.61,23.89)的参与者中; 在接受DHEA干预> 12周的参与者中(WMD:17.2 ng / ml,95%CI:8.02,26.22); 在没有潜在合并症的参与者中(WMD:19.11 ng / ml,95%CI:10.69,27.53); 以及60岁以上的参与者(WMD:19.79 ng / ml,95%CI:9.86,29.72)。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。亚组分析显示,仅女性中血清IGF-1水平有统计学上的显着提高(WMD:23.30 ng / ml,95%CI:13.75,32.87);在补充了50 mg / d DHEA(WMD:15.75 ng / ml,95%CI:7.61,23.89)的参与者中; 在接受DHEA干预> 12周的参与者中(WMD:17.2 ng / ml,95%CI:8.02,26.22); 在没有潜在合并症的参与者中(WMD:19.11 ng / ml,95%CI:10.69,27.53); 以及60岁以上的参与者(WMD:19.79 ng / ml,95%CI:9.86,29.72)。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。23.89);在接受DHEA干预> 12周的参与者中(WMD:17.2 ng / ml,95%CI:8.02,26.22); 在没有潜在合并症的参与者中(WMD:19.11 ng / ml,95%CI:10.69,27.53); 以及60岁以上的参与者(WMD:19.79 ng / ml,95%CI:9.86,29.72)。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。23.89);在接受DHEA干预> 12周的参与者中(WMD:17.2 ng / ml,95%CI:8.02,26.22); 在没有潜在合并症的参与者中(WMD:19.11 ng / ml,95%CI:10.69,27.53); 以及60岁以上的参与者(WMD:19.79 ng / ml,95%CI:9.86,29.72)。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。结论补充DHEA可能会增加血清IGF-I水平,尤其是在女性和老年受试者中。但是,在建议将DHEA用于临床之前,有必要进行进一步的研究。
