A novel biomarker of chronic inflammation, GlycA, is associated with poorer hearing by childhood. This potentially reframes hearing loss as a life-course condition with inflammatory antecedents common to other non-communicable diseases.

Telomere length was not associated with hearing acuity in children or their midlife parents.

Children with bilateral slight/mild hearing loss have lower academic, behaviour and health-related quality of life scores than normally hearing children, with some scores 0.2–0.3 standard deviations lower.
