The aetiological relationship between depressive symptoms and health-related quality of life: A population-based twin study in Sri Lanka.

ABSTRACT:

Objective

Depression often co-occurs with poor health-related quality of life (HRQL). Twin studies report genetic and individual-level environmental underpinnings in the aetiology of both depression and HRQL, but there is limited twin research exploring this association further.
