Many diseases were under-investigated due to the focus on the SARS-CoV-2 virus and the redeployment of resources to the pandemic response. This study aimed to assess Legionella trends in Ontario during the COVID-19 pandemic years, by comparing the demographics of individuals tested for Legionella prior to pandemic (2018 and 2019) to those during the pandemic (2020, 2021 and 2022).

Analysis was divided into two periods (2013-2019; 2020-2021) to account for COVID-19 disruptions. Residential segregation was measured by dissimilarity index categorized into reference (&lt; 0.25), moderate (0.26-0.50), high (0.51-0.75), and extreme (&gt; 0.75) levels. Primary outcome measures were chlamydia and gonorrhea incidence rates. Residential segregation was the key independent variable with other social determinants of health covariates. 3,211 counties within the contiguous United States were included within this study.

From 2020 to 2021, these coefficients increased (from 13 to 15 to 28.25 and 34.16), suggesting growing segregation-driven disparities.

Spatial variation in the association between segregation and chlamydia incidence remained consistent, with more pronounced associations in the Southeastern, Midwest, and Western regions.

The data were collected through a self-administered anonymous questionnaire. We collected data on the students' smoking status, age of first cigarette use, intention to quit smoking and the level of nicotine dependence among smokers. Chicha, e-cigarette, alcohol, cannabis use and other addictive behavior were also investigated through the questionnaire. A multivariate logistic regression model was employed to identify associated factors with cigarette smoking. The threshold of statistical significance was set at p < 0.05.</p><p><strong>Results: </strong>A total of 748 students participated in this study. Of all respondents, 12.6% (95% CI [10.22-14.98]) consumed at least one form of tobacco. The prevalence of cigarette smoking was 10.7% (95%CI [8.5-12.9]). Male sex (aOR = 5.12; 95%CI [2.39-10.99]), living alone or with colleagues (aOR = 3.90; 95%CI [1.49-10.23]), alcohol consumption (aOR = 20.03; 95%CI [8.66-46.32]) and a high stress level (aOR = 3.22; 95%CI [1.08-9.61]) were found to be independently associated with cigarette smoking. Conversely, smartphone addiction (aOR = 0.34; 95% CI [0.14-0.82]) was identified as being inversely associated with cigarette smoking.</p><p><strong>Conclusion: </strong>This study highlights a considerable prevalence of tobacco use among students. While several well-known factors were associated with cigarette smoking, an inverse association with smartphone addiction emerged as a novel finding. These results may help inform targeted interventions to address this public health concern among medical students.</p>","PeriodicalId":9039,"journal":{"name":"BMC Public Health","volume":"25 1","pages":"3599"},"PeriodicalIF":3.6,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145367472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
