Trend analysis and modelling of gender-specific age, period and birth cohort effects on alcohol abstention and consumption level for drinkers in Great Britain using the General Lifestyle Survey 1984-2009.
Bottom Line: This study aims to disentangle age, period and birth cohort effects to improve our understanding of these trends and suggest groups for targeted interventions to reduce resultant harms.Consumption generally decreases and abstention rates increase in later life.Recent declines in alcohol consumption appear to be attributable to reduced consumption and increased abstinence rates among the most recent birth cohorts, especially males, and general increased rates of abstention across the study period.

Mentions: The results from the negative binomial models are shown in Fig. 4 and Table A2 in the Supporting information, Appendix S2. Consumption peaks for both men and women between ages 18–24 then drops sharply, but there is a rebound, particularly for women, of slightly increased consumption between ages 45–54. Compared with the 45–54 age group, both male and female drinkers aged 18–24 drink significantly more (IRR = 1.18–1.15), whereas men aged 16–17 and 35–44 (IRR = 0.67–0.92) and women aged 25–44 (IRR = 0.89–0.95) drink significantly less. No significant decline in consumption among drinkers was seen in those aged 55+ compared with the reference group.
