Abstract

Background: Abnormalities in biochemical parameters and changes in eating habits are considered complications of obesity. Oleoylethanolamide (OEA), an endocannabinoid-like compound, has been shown to have protective effects on many metabolic disorders. Given this evidence, the present study aimed to assess the effects of OEA on lipid profile parameters, fasting blood sugar (FBS), and dietary habits in healthy obese people.

Methods: In this randomized, double-blind, placebo-controlled clinical trial, which was carried out in 2016 in Tabriz, Iran, 60 obese people were enrolled in the study based on inclusion criteria. The intervention group consumed 125 mg of OEA capsules, and the placebo group received the same amount of starch twice for 8 weeks. Blood samples (5 mL) were taken at baseline and the end of the study in a fasting state. Serum concentrations of FBS, triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), and total cholesterol (TC) were measured by enzymatic methods using commercial kits. The low-density lipoprotein cholesterol (LDL-C) concentration was obtained using the Friede-Wald formula. To assess dietary habits, a food frequency questionnaire (147 items) was used at baseline and the end of the study. A value less than < 0.05 was considered to indicate statistical significance.

Results: The TG concentration decreased significantly in the intervention group (mean (SD): 166.29 (70.01) mg/dL to 142.22 (48.05) mg/dL, p = 0.047). Changes in the placebo group were not significant (p > 0.05). After adjusting for baseline values and demographic characteristics, the difference in TG between groups remained significant (p = 0.044). Changes in other biochemical parameters were not significant. There was no significant difference between or within groups in terms of food groups.

Conclusion: OEA, as a complementary agent, plays a protective role in TG regulation. However, future studies with longer durations are needed to explore the impact of OEA on regulating dietary habits and to identify the mechanisms related to metabolic abnormalities in obese people.

Trial registration: The study was registered in the Iranian Registry of Clinical Trials (IRCT) center as IRCT201607132017N30 with URL. www.IRCT.IR in date 03/10/2016.

补充油酰乙醇酰胺对肥胖者血脂、空腹血糖和饮食习惯的影响:随机双盲安慰剂对照试验。
背景:生化指标异常和饮食习惯改变被认为是肥胖症的并发症。油酰乙醇酰胺(OEA)是一种类似于内源性大麻素的化合物,已被证明对许多代谢紊乱具有保护作用。鉴于这些证据,本研究旨在评估 OEA 对健康肥胖者的血脂谱参数、空腹血糖(FBS)和饮食习惯的影响:这项随机、双盲、安慰剂对照临床试验于 2016 年在伊朗大不里士进行,根据纳入标准,60 名肥胖者被纳入研究。干预组服用 125 毫克 OEA 胶囊,安慰剂组两次服用相同量的淀粉,为期 8 周。分别在基线和研究结束时空腹抽取血液样本(5 毫升)。血清中的 FBS、甘油三酯(TGs)、高密度脂蛋白胆固醇(HDL-C)和总胆固醇(TC)的浓度是通过酶法使用商业试剂盒测定的。低密度脂蛋白胆固醇(LDL-C)浓度采用弗里德-瓦尔德公式计算得出。为了评估饮食习惯,在基线和研究结束时使用了食物频率问卷(147 项)。结果干预组的 TG 浓度明显降低(平均值(标清):166.29 (70.01) mg/dL 降至 142.22 (48.05) mg/dL,p = 0.047)。安慰剂组的变化不显著(p > 0.05)。调整基线值和人口统计学特征后,各组之间的总胆固醇差异仍然显著(p = 0.044)。其他生化指标的变化不显著。在食物组别方面,组间和组内均无明显差异:结论:作为一种补充剂,OEA 对总胆固醇的调节具有保护作用。结论:OEA 作为一种补充剂,在调节总胆固醇方面发挥着保护作用。不过,今后还需要进行持续时间更长的研究,以探讨 OEA 对调节饮食习惯的影响,并确定与肥胖者代谢异常有关的机制:该研究已在伊朗临床试验注册中心(IRCT)注册,注册号为 IRCT201607132017N30,网址为 www.IRCT.IR,注册日期为 2016 年 10 月 3 日。
