Hearing loss is a prevalent health concern, and dietary factors, such as fatty acid intake, may play a role in its development. The current study aimed to investigate the association between the intake of dietary fatty acids and hearing thresholds among U.S. adults.
The researchers examined data from the National Health and Nutrition Examination Survey (NHANES), including 7,623 participants with available dietary fatty acid intake and audiometry data. Dietary fatty acid intake was assessed using dietary recalls, and hearing thresholds were measured using pure-tone audiometry. Multivariate linear regression models and smoothing curve fitting were utilized to explore the associations between dietary fatty acid intake and hearing thresholds, adjusting for relevant covariates.
This study reveals a direct association between both low and high frequency pure tone average (PTA) hearing thresholds and the dietary intake of total saturated fatty acids (SFAs) and total polyunsaturated fatty acids (PUFAs). Conversely, the intake of total monounsaturated fatty acids (MUFAs) demonstrates an inverted U-shaped correlation with low-frequency and high-frequency PTA hearing thresholds, having inflection points at 11.91 (energy (%)) and 10.88 (energy (%)), respectively.
Dietary intake of certain fatty acids may influence hearing thresholds in adults.
听力损失是一个普遍存在的健康问题，饮食因素，如脂肪酸摄入，可能在其发展中起作用。本研究旨在调查美国成年人膳食脂肪酸摄入与听力阈值之间的关系。
研究人员检查了国家健康和营养检查调查（NHANES）的数据，包括 7623 名有可用饮食脂肪酸摄入和听力计数据的参与者。饮食脂肪酸摄入通过饮食回忆进行评估，听力阈值通过纯音听力计进行测量。利用多元线性回归模型和平滑曲线拟合来探索膳食脂肪酸摄入与听力阈值之间的关系，并调整相关协变量。
本研究揭示了总饱和脂肪酸（SFA）和总多不饱和脂肪酸（PUFA）的饮食摄入与低频和高频纯音平均（PTA）听力阈值之间存在直接关联。相反，总单不饱和脂肪酸（MUFA）的摄入与低频和高频 PTA 听力阈值呈倒 U 型相关，拐点分别为 11.91（能量（%））和 10.88（能量（%））。
某些脂肪酸的饮食摄入可能会影响成年人的听力阈值。
