MedicalResearch.com: What is the background for this study? What are the main findings?
Response: We investigated how the different intake of alcohol relates to all-cause and cause-specific hospitalizations. In particular, we mainly investigated the association of alcohol consumption with total number of hospitalizations that occurred during 6 years of follow-up.
We also examined cause-specific hospitalizations (e.g., alcohol-related diseases, vascular diseases, cancer, traumatic injury, and neurodegenerative diseases).

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: This study is the first to show that daily drinking is dangerous. Specifically, drinking four or more times weekly, even if it’s only 1-2 drinks at a time, increases risk of mortality. This is in line with recent studies published in the Lancet, but we were able to break down their lowest drinking categories (up to 12.5 drinks weekly in one and up to 5.6 drinks weekly in the other) and found that the frequency is important, not just the average number of drinks per week. It looks like the increased mortality is predominantly due to cancer-related deaths.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Most of what we know about the time course of drinking too much (at-risk use) is from people in treatment or special groups and not adults in the US population at large. That’s why we did this study. We need to know how often at-risk drinking persists, how often it resolves, and how often it appears de novo.
Risky drinking means exceeding limits that are associated with health consequences. It includes people with an alcohol use disorder but the vast majority of people drinking risky amounts do not have a disorder, they are simply drinking amounts that can harm their health. Even low amounts can harm health (e.g. breast cancer risk increases at <1 drink a day) but substantial increases in risk occur over 7 in a week on average (for women, and 14 for men) or >5 for men (>4 for women) on an occasion. The latter are associated with acute consequences (e.g. injury, unwanted sex), and the former with chronic conditions (e.g. cirrhosis). People should be aware of their risks and then they can make choices about what risks they want to take (and for those with a disorder, they may need help with those choices and help changing behavior like treatment). These are all useful thing to talk to any young adults about before they set off on a stag do in Krakow or any other city!
The main findings were….that 3 years later, 3/4ths of adults drinking risky amounts were still doing so. But importantly, a quarter had stopped drinking risky amounts. It is important to know that things change. One factor associated with that positive change was having kids—presumably a positive social change even if stressful. Of those adults not drinking risky amounts when first interviewed, 15% started doing so 3 years later. Again having children was protective but the main factor associated with starting was young age, particularly those who became of legal drinking age. Despite the fact that youth may be able to access alcohol illegally, this finding confirms that the drinking age of 21 in the US does in fact restrict access, and that turning 21 increases use and risky use by making alcohol more accessible.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The association of heavy drinking with dementia has been known for decades. For instance, there is about no Wernicke–Korsakoff syndrome without heavy drinking and the syndrome was described in 1890. But this type of dementia is very rare. Also, heavy drinking is knowingly associated with multiple risk factors for dementia onset such as hypertension or diabetes. But heavy drinkers generally refuse to participate to cohort studies and declaration of alcohol use among participants is generally biased downward... So the study rationale is very strong, but supporting empirical evidence is quite scarce.
This nationwide study included all 31+ million adults discharged from hospitals over 6 years, i.e., 50% of the French population before 65 years old and 80% above that age. Of 1.1+ million adults diagnosed with dementia, one in twenty had an early-onset (before 65 years old). Heavy drinking was recorded in most (56%) early-onset dementia cases: two-third in men; one-third in women. In addition, the association of heavy drinking with dementia goes far beyond 65 years old, both directly (>3 times higher risk for dementia onset after controlling for more than 30 known risk factors for dementia) and indirectly as heavy drinking was associated with all other independent risk factors for dementia onset. Accordingly, heavy drinking had the largest effect on dementia risk of all independent modifiable risk factors such as hypertension or diabetes.
The effects were found whatever dementia case definition or population studies.
