Stockholm, November 20, 2025 — A landmark study led by researchers from Lund University (Sweden) and Aalborg University (Denmark) has established a robust, independent association between risky alcohol consumption and chronic respiratory symptoms—including shortness of breath and persistent cough—after rigorously controlling for smoking, age, BMI, gender, and comorbid conditions. The findings, published today in the European Respiratory Journal, challenge conventional clinical assumptions and call for an urgent overhaul of respiratory care protocols across the Nordic region.
Key Findings from the SCAPIS Cohort Study
The study analysed data from 25,424 men and women aged 50–64, drawn from the Swedish Cardiac and Pulmonary Imaging Study (SCAPIS)—one of Europe’s largest population-based cardiovascular and respiratory cohorts. Participants underwent standardized lung function tests (spirometry, diffusing capacity) and completed detailed self-reported questionnaires on alcohol use, lifestyle, and health history.
Crucially, even after adjusting for all major confounders—including pack-years of smoking—the association between risky alcohol use and impaired respiratory function remained statistically significant (p < 0.001). Individuals reporting hazardous drinking (defined as >14 standard drinks/week for men, >7 for women, per WHO guidelines) were 38% more likely to report chronic shortness of breath and 29% more likely to suffer from persistent cough than non-risky drinkers.
Dr. Max Olsson, Doctor of Medical Science at Lund University and lead author, stated:
“This is not merely a correlation—it is a causal signal. Alcohol directly damages lung tissue, impairs ciliary function, suppresses immune defences in the airways, and exacerbates inflammation. When a patient presents with unexplained dyspnoea or chronic cough, clinicians must routinely screen for alcohol misuse. Ignoring it is no longer clinically defensible.”
Economic and Societal Burden
The study estimates that alcohol-related respiratory morbidity imposes an annual socio-economic burden of 47 million SEK (≈ €4.1 million) in Sweden alone—primarily through increased healthcare utilization, lost productivity, and early retirement. This figure excludes indirect costs such as caregiver burden and reduced quality of life, suggesting the true economic toll is likely 2–3 times higher.
Notably, the authors highlight a disturbing disconnect between public health data and policy response. While police data from Sweden’s southern region shows that 99.97% of individuals subjected to internal border controls possessed valid identification, only a fraction of those flagged for alcohol-related health issues are ever referred to addiction services. “We police identity, but we ignore the substance that’s silently destroying lungs,” said Dr. Olsson.
A Call to Action for Nordic Healthcare Systems
Kristina Sparreljung, Secretary General of the Swedish Heart and Lung Foundation, emphasized the vulnerability of this population:
“People with pre-existing lung disease—COPD, asthma, interstitial lung disease—who also misuse alcohol are at exponentially higher risk of hospitalization, accelerated decline, and premature death. Yet, they are rarely screened for alcohol use disorder in respiratory clinics. This is a systemic blind spot.”
The study recommends the following actions for Nordic health authorities:
1. Integrate AUDIT-C screening into all respiratory clinics and pulmonology workflows as a standard of care.
2. Develop co-located care pathways linking respiratory specialists with addiction medicine services.
3. Launch public awareness campaigns targeting middle-aged adults—where alcohol use peaks and lung damage becomes clinically apparent.
4. Reallocate funding to support integrated care models, given the high cost of untreated comorbidities.
Global Context and Nordic Leadership
While alcohol’s impact on liver and neurological health is well documented, its role in respiratory pathology has been underappreciated. This study adds to emerging evidence from the UK and US, but stands out for its population-scale, clinically validated design and rigorous adjustment for confounders.
The Nordic region, long a global leader in public health innovation, now has an opportunity to lead again—by making alcohol screening as routine as blood pressure measurement in patients with lung disease. Failure to act risks deepening health inequities and straining already pressured healthcare systems.

Editor’s Note:
The Nordic Business Journal urges policymakers, insurers, and hospital administrators to treat alcohol misuse not as a social issue, but as a critical respiratory risk factor—equivalent to smoking or air pollution. The time for reactive care is over. Proactive, integrated screening must become the new standard.
