>We used a regression model with RBA as the response variable and with smoking amount, alcohol consumption amount, sex, and education as predictors.
>Each additional pack-year of smoking was associated with 0.03 years of increased RBA (p-value=2E-8);
>each additional gram of alcohol consumption per day was associated with 0.02 years of increased RBA (p-value=6E-10).
The study is called Association of relative brain age with tobacco smoking, alcohol consumption, and genetic variants. It's available for free on Nature.
Is it just more or is the part about alcohol worded in a weird way? The way I get it, it's meant as "for every year of 1g of alcohol consumption per day" or else you'd arrive at absurd values for RBA for people who drink like 6 beers per week.
