Key result
Consistent midlife heavy drinking is linked to ~0.02 mm greater cIMT vs stable moderate drinking.
Why the study?
The effect of alcohol consumption on atherosclerotic changes in vessel walls is disputed, with most studies relying on cross-sectional data that may misrepresent cumulative harm.
Does consistent heavy alcohol consumption over 20 years during midlife increase carotid intima media thickness in early old age compared to stable moderate drinking?
Cohort (n=5,403)
Yes
Does consistent heavy alcohol consumption over 20 years during midlife increase carotid intima media thickness in early old age compared to stable moderate drinking?
Mean Difference: 0.021 (95% CI 0.002–0.039)
Sustained heavy drinking over 20 years in midlife is associated with increased atherosclerotic thickening compared to stable moderate drinking, while moderate drinking offers no atherosclerotic benefit over non-drinking.
No takes yet. Share an insight, caveat, or question.
Sustained heavy midlife drinking trajectories were associated with higher cIMT; extends cross-sectional data and leaves open causal inference for prospective studies.
Britton et al. (2016) conducted a cohort in Atherosclerosis (n=5,403). Consistent heavy drinking vs. Stable moderate drinking was evaluated on Carotid intima media thickness (cIMT) (MD 0.021 mm, 95% CI 0.002 to 0.039). Consistent heavy drinking over a 20-year period during midlife was associated with an increased carotid intima media thickness compared to stable moderate drinking (pooled difference 0.021 mm).
