Bidirectional associations between alcohol consumption and health-related quality of life amongst young and middle-aged women.

ABSTRACT:

Background

Evidence from cross-sectional studies has suggested a positive association between moderate alcohol consumption and health-related quality of life but prospective data remain scarce.

Objectives

To examine the bidirectional relationships between alcohol consumption and health-related quality of life using a longitudinal study design.

Methods

A total of 92 448 participants of the Nurses' Health Study II reported their alcohol consumption (in 1991, 1995, 1999 and 2003) and health-related quality of life (in 1993, 1997 and 2001). Using generalized estimating equations, we modelled the physical and mental component summary (PCS and MCS) scores as a function of alcohol consumption 2 years earlier (n = 88 363) and vice versa (n = 84 621).
