Contributing factors to the development of tinnitus encompass aging, exposure to loud noise, smoking, and hearing impairment. Nevertheless, the precise risk factors, particularly those that can be modified, remain uncertain. This study aimed to explore the potential genetic factors that may be associated with an increased susceptibility to tinnitus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Mendelian randomization analyses were performed using data from the United Kingdom Biobank and the FinnGen Biobank data infrastructure. The present study examined the correlation between 13 prevalent life factors, which were identified as potential risk factors for tinnitus through a comprehensive review of the literature. The inverse-variance weighted model was employed to analyze the associations. To mitigate database source bias and strengthen the reliability of our findings, data from the United Kingdom Biobank were used for the discovery cohort, whereas data from FinnGen were used for the validation cohort. Subsequently, a meta-analysis was conducted to combine the findings, thereby bolstering the robustness of the results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the United Kingdom Biobank discovery cohort, waist circumference (odds ratio = 1.37, 95% confidence interval 1.09\u20131.71, p\u2009=\u20090.006), waist-to-hip ratio (odds ratio = 1.71, 95% confidence interval 1.17\u20132.50, p\u2009=\u20090.005), fasting glucose (odds ratio = 0.70, 95% confidence interval 0.54\u20130.90, p\u2009=\u20090.007), and fasting insulin (odds ratio = 2.07, 95% confidence interval 1.07\u20134.01, p\u2009=\u20090.03) showed significant associations with tinnitus. In the FinnGen validation cohort, smoking was associated with tinnitus (odds ratio = 1.20, 95% confidence interval 1.03\u20131.40, p\u2009=\u20090.018). However, in the meta-analysis combining both cohorts, only waist circumference remained significantly associated with tinnitus (odds ratio = 1.27, 95% confidence interval 1.08\u20131.49, p\u2009=\u20090.003).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings indicate a causal relationship between waist circumference, an indicator of central obesity, and tinnitus. This implies that abdominal obesity could serve as a modifiable target for the prevention of tinnitus.
