摘要: 背景 尽管单不饱和脂肪酸(MUFA)摄入与非酒精性脂肪性肝病(NAFLD)的关联已受到关注,但在中国人群中的研究较少。 目的 探讨中国人群MUFA每日摄入量与NAFLD发病率之间的关联,并确定MUFA摄入量对NAFLD风险的潜在阈值。 方法 本研究数据从Dryad数据库获取并严格遵守Dryad的服务条款(https://doi.org/10.5061/dryad.8nn2j46)。选取2015年4月—2017年8月在福建医科大学附属南平第一医院治疗的534例NAFLD患者作为病例组,选取同期534例体检健康者作为对照组。使用半定量食物频率问卷(SQFFQ)收集参与者的典型食物消费信息,并计算MUFA每日摄入量。采用综合分析策略,包括基线特征、多变量统计、非线性关系及亚组探究,探讨MUFA每日摄入量与NAFLD发病率的关联,同时考虑多种混杂因素如年龄、性别、生活方式和其他饮食成分,以确定MUFA对NAFLD风险的潜在阈值。 结果 在调整模型中,MUFA每日摄入量是NAFLD风险的影响因素(OR=1.04,95%CI=1.02~1.07,P<0.001)。将MUFA每日摄入量转换为分类变量后,在调整模型中,随着MUFA每日摄入量的增加,NAFLD风险呈增加趋势(P趋势<0.001)。非线性分析表明,当MUFA每日摄入量达到39.04 g/d时,其与NAFLD风险的关系发生显著变化(P=0.045)。MUFA每日摄入量<39.04 g/d时,NFALD风险为1.08(95%CI=1.04~1.11,P<0.001)。亚组分析结果显示,性别、年龄、能量每日摄入量与NAFLD风险间存在交互作用(P交互<0.05)。 结论 增加MUFA每日摄入量与较高的NAFLD风险相关,并在特定阈值(39.04 g/d)后呈现非线性关系。这一发现强调了在NAFLD管理中考虑饮食脂肪的质量和数量的重要性。

Abstract:

Background

While the connection between monounsaturated fatty acid (MUFA) intake and non-alcoholic fatty liver disease (NAFLD) has received attention, research in Chinese populations remains scarce.

Objective

This study aims to evaluate the association between daily MUFA intake and the prevalence of NAFLD in a Chinese population and to estimate the probable threshold of MUFA intake for NAFLD risk.

Methods

This case-control study employed data from the Dryad database (https://doi.org/10.5061/dryad.8nn2j46), complying with Dryad's terms of service. We collected data from 534 NAFLD patients and 534 healthy controls who underwent medical tests at the First Hospital of Nanping Affiliated to Fujian Medical University between April 2015 and August 2017. A semi-quantitative food frequency questionnaire (SQFFQ) was used to collect individuals' typical food consumption information, and daily MUFA intake was computed. A thorough analytical technique, including baseline characteristics, multivariate statistics, non-linear relationship analysis, and subgroup research, was applied to study the correlation between daily MUFA intake and NAFLD prevalence. Multiple confounding factors, such as age, sex, lifestyle, and other dietary components, were evaluated to estimate the theoretical threshold of MUFA intake for NAFLD risk.

Results

In the adjusted model, daily MUFA intake was a significant risk factor for NAFLD (OR=1.04, 95%CI=1.02-1.07, P<0.001). After transforming daily MUFA intake into a categorical variable, the adjusted model demonstrated an increased trend of NAFLD risk with increasing daily MUFA intake (Ptrend<0.001). At 39.04 g/d, non-linear analysis revealed a significant change in the relationship between daily MUFA intake and NAFLD risk. When daily MUFA intake was <39.04 g/d, the risk of NAFLD was 1.08 (95%CI=1.04-1.11, P<0.001). Subgroup analysis revealed significant interactions between sex, age, daily engery intake, and NAFLD risk (Pinteraction<0.05) .

Conclusion

Increased daily MUFA intake was related to a greater risk of NAFLD, demonstrating a non-linear relationship after a certain threshold (39.04 g/d). This finding shows the need for evaluating both the quality and quantity of dietary fat in NAFLD management.
