Abstract

Background: Epidemiological research links asthma progression to dietary nonallergic factors, particularly high-calorie intake. However, evidence supporting the relationship with total dietary calorie consumption remains scarce.

Objective: This study aimed to explore the potential correlation between asthma occurrence and total dietary energy intake.

Methods: A retrospective cross-sectional study of 21,354 US adults collected comprehensive participant data, including demographics, blood parameters, fatty acids, zinc, fiber intake, and asthma outcomes. Statistical analyses included interaction effects analysis, smooth curve fitting, and logistic regression.

Results: Of 21,354 participants, 14.77% self-reported asthma diagnosis. After adjusting for confounders, odds ratios (OR) for asthma decreased with higher energy intake: Q2 (OR = 0.77, 95% CI: 0.69-0.86, p < .001), Q3 (OR = 0.66, 95% CI: 0.59-0.75, p < .001), and Q4 (OR = 0.61, 95% CI: 0.53-0.69, p < .001) compared to Q1 (< 17.73 kcal/kg/day). A non-linear (L-shaped) association between energy intake and asthma was observed (p < .001), with a critical threshold around 24 kcal/kg/day, supported by subgroup and sensitivity analyses.

Conclusion: This study reveals an L-shaped trend between total energy intake and asthma in US adults, with a significant threshold at approximately 24 kcal/kg/day.

美国成人哮喘与膳食总能量摄入量之间的关系：NHANES 的回顾性横断面分析。

背景：流行病学研究表明，哮喘的发展与饮食中的非过敏因素有关，尤其是高热量摄入。然而，支持这种关系的证据仍然很少：本研究旨在探讨哮喘发生与膳食总能量摄入之间的潜在相关性：一项针对 21,354 名美国成年人的回顾性横断面研究收集了全面的参与者数据，包括人口统计学、血液参数、脂肪酸、锌、纤维摄入量和哮喘结果。统计分析包括交互效应分析、平滑曲线拟合和逻辑回归：在 21 354 名参与者中，14.77% 的人自我报告确诊为哮喘。在对混杂因素进行调整后，哮喘的几率比（OR）随着能量摄入的增加而降低：Q2（OR = 0.77，95% CI：0.69-0.86，P 结论：本研究揭示了美国成年人总能量摄入与哮喘之间的 L 型趋势，其中约 24 千卡/千克/天是一个显著的临界值。
