Article Synopsis
  • A study analyzed lung cancer cases in France during the COVID-19 pandemic by comparing 2020-2021 data with pre-pandemic years (2013-2019), focusing on diagnosis and mortality rates.
  • Findings revealed a 12% decrease in newly diagnosed lung cancer cases during the first wave of the pandemic, with a continued improvement in survival rates over time, even during the pandemic.
  • The decrease in lung cancer incidences could be linked to undiagnosed patients who died due to COVID-19 or challenges in accessing healthcare, leading to excess mortality during this period.

We investigated the mortality patterns of chronic obstructive pulmonary disease (COPD) patients in France relative to a control population, comparing year 2020 to pre-pandemic years 2017-2019. COPD patient and sex, age and residence matched control cohorts were created from the French National Health Data System. Survival was analyzed using Cox regressions and standardized rates.

This study aims to ascertain occupations potentially at greatest risk of exposure to SARS-CoV-2 based on pre-lockdown working conditions in France. We combined two French population-based surveys documenting workplace exposures to infectious agents, face-to-face contact with the public, and working with colleagues just before the pandemic. Then, for each 87-level standard French occupational grouping, we estimated the number and percentage of the French working population reporting these occupational exposure factors, by gender, using survey weights.

Purpose: The "alcohol harm paradox" has been evidenced among adults, but it is still largely unexplored among adolescents. We examined in a sample of French adolescents the relation between family socioeconomic status (SES), family living arrangement and parental substance use on 1 hand, and heavy episodic drinking (HED), lifetime alcohol-induced emergency room visits (A-ERV), and number of alcoholic drinks and solitary drinking during the last episode on the other hand.

Methods: A cross-sectional nationwide survey in March 2017 involved 13,314 French adolescents aged 17-18.
