Within-person change in alcohol consumption and associated factors during a public health crisis.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrevious studies have reported different patterns of change in alcohol consumption during the COVID-19 pandemic, varying across countries and time periods. While some studies report an overall decrease in alcohol use, others describe an increase. This study aimed to investigate within-person changes in alcohol consumption specifically in the French population between 2018 and 2020 during the COVID-19 pandemic, and to identify the factors associated with these changes.
methodsWe used longitudinal data from the French TEMPO cohort, established in 2009 among young adults, to examine within-person changes in alcohol consumption between 2018 and 2020. Data collected in 2018 and during the 2020 lockdown periods were analyzed for 607 participants using a multinomial mixed-effects regression model.
resultsApproximately one-third of the study sample did not change their alcohol consumption between 2018 and 2020 (31.7%). While 24.4% experienced a moderate increase, 21.4% had a moderate decrease, 12.4% a large increase, and 10.0% a large decrease. Men had nearly three times higher odds of experiencing a large decrease in alcohol consumption, rather than maintaining a stable level of consumption, compared to women (95%CI = 1.88–5.49). Regular smokers had lower odds of experiencing a large decrease in alcohol consumption rather than maintaining a stable consumption compared to non-smokers (OR = 0.57, 95%CI = 0.35–0.93).
conclusionsOur study revealed different trends in alcohol consumption between 2018 and 2020, with most participants maintaining a consistent level of alcohol consumption, while some modestly increased it. This study enabled us to identify vulnerable groups which require particular attention and monitoring in the event of other health, economic, social, or climate-related crises.
