Abstract

Background

Excessive visceral adipose tissue (VAT) is a key driver of metabolic diseases, yet modifiable dietary strategies for VAT reduction remain underexplored.

Objective

This cross-sectional study examined the association between dietary fiber intake and visceral fat volume in U.S. adults.

Methods

Using 2011–2018 NHANES data from 9111 adults aged 20–59 years, dietary fiber intake was assessed via two 24-hour recalls, and VAT volume was measured by DXA. Weighted gamma regression models adjusted for age, sex, BMI, and lifestyle factors evaluated dose-response relationships.

Results

Higher fiber intake was inversely associated with VAT volume (P for trend <0.001). Compared to the lowest intake group (<15 g/day), adjusted VAT reductions were 4.1 % (95 % CI: 2.3–5.9 %), 7.6 % (4.4–10.6 %), and 6.8 % (2.8–10.6 %) for 15–25, 25–35, and > 35 g/day groups, respectively. Restricted cubic splines confirmed linearity (P = 0.67), with stronger effects in females. Sensitivity analyses excluding extreme intake values (>60 g/day) validated robustness.

Conclusion

Increased dietary fiber intake is associated with lower visceral adiposity, suggesting a potential strategy for mitigating metabolic risk in U.S. adults.

膳食纤维摄入量与内脏脂肪量之间的关系：基于NHANES 2011-2018的横断面研究

背景：过多的内脏脂肪组织（VAT）是代谢性疾病的关键驱动因素，然而可改变的饮食策略减少VAT仍未被充分探索。目的：本横断面研究探讨了美国成年人膳食纤维摄入量与内脏脂肪量之间的关系。方法：使用9111名年龄在20-59岁的成年人2011-2018年的NHANES数据，通过两次24小时召回评估膳食纤维摄入量，并通过DXA测量VAT体积。校正了年龄、性别、BMI和生活方式因素的加权伽玛回归模型评估了剂量-反应关系。结果：高纤维摄入量与VAT体积呈负相关（P为趋势值 35 g/d组）。限制三次样条证实了线性关系（P = 0.67），雌性的影响更强。排除极端摄入量（bbb60 g/天）的敏感性分析验证了稳健性。结论：增加膳食纤维摄入量与降低内脏脂肪有关，这提示了降低美国成年人代谢风险的潜在策略。

期刊介绍： The aim of Obesity Research & Clinical Practice (ORCP) is to publish high quality clinical and basic research relating to the epidemiology, mechanism, complications and treatment of obesity and the complication of obesity. Studies relating to the Asia Oceania region are particularly welcome, given the increasing burden of obesity in Asia Pacific, compounded by specific regional population-based and genetic issues, and the devastating personal and economic consequences. The journal aims to expose health care practitioners, clinical researchers, basic scientists, epidemiologists, and public health officials in the region to all areas of obesity research and practice. In addition to original research the ORCP publishes reviews, patient reports, short communications, and letters to the editor (including comments on published papers). The proceedings and abstracts of the Annual Meeting of the Asia Oceania Association for the Study of Obesity is published as a supplement each year.
