Abstract

Background

Disabling hearing loss affects ∼430 million people globally. Fish consumption and long-chain n-3 polyunsaturated fatty acid (PUFA) intake were inversely associated with risk of hearing loss, but the association of plasma n-3 PUFAs and hearing loss is unclear.

Objective

To examine the associations between plasma n-3 PUFA fractions (as % of total fatty acids), i.e., DHA % and Other n-3 PUFA % (defined as total n-3 PUFA minus DHA), with self-reported hearing difficulty in a population-based cohort in the UK.

Methods

Our study includes 175,177 UK Biobank participants (40–69y, 54 % women) with data on plasma n-3 PUFA and hearing status. Baseline plasma PUFA levels were analyzed by nuclear magnetic resonance, and self-reported hearing difficulty was obtained by questionnaire between 2007 and 2010. Logistic regression was used to estimate age-adjusted odds ratios (ORs), multivariable-adjusted odds ratios (MVORs) by adjusting for 14 demographic, behavioral, biomarker and health-related potential confounders, and 95 % confidence intervals (CIs).

Results

Hearing difficulty was reported by 26.7 % of participants. Higher plasma n-3 PUFA levels were independently associated with lower odds of self-reported hearing difficulty. The prevalence of hearing difficulty rose across age strata (40–49y, 15.8 %; 50–59y, 24.9 % and 60+y, 34.4 %; p < 0.0001) and overall was higher in males (33.2 %) than females (21.3 %). Compared with those in the lowest quintile of plasma DHA % or Other n-3 PUFA %, the MVOR (95 % CI) for hearing difficulty was 0.88 (0.85, 0.92) in highest quintile of plasma DHA %, and 0.91 (0.87, 0.94) in the highest quintile of Other n-3 PUFA %. The associations with DHA % did not differ by age or sex (p-for-interaction 0.83 and 0.58, respectively). MVORs for DHA % and Other n-3 PUFA % were similar among the 44,486 individuals with data on noise exposure at work.

Conclusions

Higher plasma n-3 PUFA levels were independently associated with lower odds of hearing difficulty.

英国生物库队列中血浆 n-3 脂肪酸水平与自述听力困难的横断面分析

背景全球有 4.3 亿人患有致残性听力损失。鱼类摄入量和长链 n-3 多不饱和脂肪酸 (PUFA) 摄入量与听力损失风险成反比，但血浆 n-3 PUFA 与听力损失的关系尚不清楚、我们的研究包括 175,177 名英国生物库参与者（40-69 岁，54% 为女性），他们都提供了血浆 n-3 PUFA 和听力状况的数据。通过核磁共振分析了血浆 PUFA 的基线水平，并在 2007 年至 2010 年期间通过问卷调查获得了听力困难的自我报告。采用逻辑回归法估算了年龄调整后的几率比（ORs）、多变量调整后的几率比（MVORs）（调整了 14 个人口统计学、行为学、生物标志物和健康相关的潜在混杂因素）以及 95% 的置信区间（CIs）。较高的血浆 n-3 PUFA 水平与较低的自我报告听力困难几率独立相关。不同年龄段的听力障碍发生率均有所上升（40-49 岁，15.8%；50-59 岁，24.9%；60 岁以上，34.4%；p < 0.0001），男性（33.2%）的听力障碍发生率总体高于女性（21.3%）。与血浆 DHA % 或其他 n-3 PUFA % 最低五分位数的人群相比，血浆 DHA % 最高五分位数人群的听力困难 MVOR（95 % CI）为 0.88（0.85，0.92），其他 n-3 PUFA % 最高五分位数人群的听力困难 MVOR 为 0.91（0.87，0.94）。年龄或性别与 DHA 百分比的关系没有差异（交互作用 p 分别为 0.83 和 0.58）。在有工作噪音暴露数据的 44,486 人中，DHA % 和其他 n-3 PUFA % 的 MVORs 相似。
