    ABSTRACT: Despite the high prevalence of snoring in Asia, little is known about the genetic etiology of snoring and its causal relationships with cardiometabolic traits. Based on 100,626 Chinese individuals, a genome-wide association study on snoring was conducted. Four novel loci were identified for snoring traits mapped on SLC25A21, the intergenic region of WDR11 and FGFR, NAA25, ALDH2, and VTI1A, respectively. The novel loci highlighted the roles of structural abnormality of the upper airway and craniofacial region and dysfunction of metabolic and transport systems in the development of snoring. In the two-sample bi-directional Mendelian randomization analysis, higher body mass index, weight, and elevated blood pressure were causal for snoring, and a reverse causal effect was observed b

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Discuss with your doctor

  • Snoring and sleep apnea risk management Moderate

    Habitual snoring increases risk of obstructive sleep apnea and associated cardiovascular complications

    Discuss snoring symptoms with physician; assess cardiovascular and metabolic health if frequent snoring develops

Lifestyle

  • Weight management Moderate

    Obesity causally increases snoring risk via airway compression; SLC25A21 genetic variants add independent risk

    Maintain BMI 18.5-25 kg/m2; reduce by 5-10% if overweight

Screening

  • Blood pressure screening Moderate

    Elevated blood pressure causally increases snoring risk; genetic predisposition via SLC25A21 increases baseline vulnerability

    Annual checks; more frequent if systolic >130 mmHg or diastolic >80 mmHg

  • Habitual snoring assessment Moderate

    rs11418337 C allele increases habitual snoring susceptibility through effects on mitochondrial function and upper airway structure

    Self-assess snoring frequency weekly; seek partner corroboration; consider sleep study if frequent snoring
