We investigated the association between annual ambient concentrations of air pollutants (fine particulate matter [PM2.5] and nitrogen dioxide [NO2]) and systolic blood pressure (SBP) among adolescents in Montr\u00e9al, Canada.<\/p>\n                  <\/sec>\n                  <sec>\n                    <title>Methods<\/title>\n                    <p>Participants were students aged 15 to 17 years who provided SBP and residential postal code data in 2004\/05 through their enrolment in the Nicotine Dependence in Teens study. Annual estimates for 2004 of residential exposure to NO2 and PM2.5 were provided by the Canadian Urban Environmental Health Research Consortium and linked to participants\u2019 residential postal code. Elevated SBP was defined as SBP \u2265 90th percentile adjusted for age, sex and height. Logistic regression was used to estimate odds ratios and 95% confidence intervals (CIs) for each pollutant with respect to elevated SBP, adjusted for relevant confounders.<\/p>\n                  <\/sec>\n                  <sec>\n                    <title>Results<\/title>\n                    <p>The sample consisted of 508 adolescents (mean age: 16.9, 46% male); 4% had elevated SBP. Although estimates were not statistically significant, there were generally modest positive associations between pollutant levels and SBP. The adjusted prevalence odds ratio of elevated SBP was 1.33 (95% CI: 0.64, 3.05) for every interquartile range (IQR) increase in residential PM2.5 levels (2.1\u03bcg\/m3). Similarly, the adjusted prevalence odds ratio of elevated SBP was 1.17 (95% CI: 0.47, 2.70) for every IQR increase in residential NO2 levels (10.2 ppb).<\/p>\n                  <\/sec>\n                  <sec>\n                    <title>Conclusion<\/title>\n                    <p>Findings support a possible relationship between exposure to air pollutants and increased SBP in adolescents, warranting further investigation for this important public health concern.<\/p>\n                  <\/sec>","DOI":"10.24095\/hpcdp.43.4.04","type":"journal-article","created":{"date-parts":[[2023,4,11]],"date-time":"2023-04-11T12:02:00Z","timestamp":1681214520000},"page":"191-198","source":"Crossref","is-referenced-by-count":6,"title":["Association between annual exposure to air pollution and systolic blood pressure among adolescents in Montr\u00e9al, Canada"],"prefix":"10.24095","volume":"43","author":[{"given":"Erica","family":"Marrone","sequence":"first","affiliation":[{"name":"Department of Family Medicine, McGill University, Montr\u00e9al, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Longo","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine and Department of Pediatric Respiratory Medicine, University of Amsterdam, Amsterdam, North Holland, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"O\u2019Loughlin","sequence":"additional","affiliation":[{"name":"School of Public Health, University of Montr\u00e9al, Montr\u00e9al, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul J.","family":"Villeneuve","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Carleton University, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Zappitelli","sequence":"additional","affiliation":[{"name":"Division of Nephrology, The Hospital for Sick Children, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gillian","family":"Bartlett-Esquilant","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, McGill University, Montr\u00e9al, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tracie A.","family":"Barnett","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, McGill University, Montr\u00e9al, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10188","container-title":["Health Promotion and Chronic Disease Prevention in Canada"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.canada.ca\/en\/public-health\/services\/reports-publications\/health-promotion-chronic-disease-prevention-canada-research-policy-practice\/vol-43-no-4-2023\/association-exposure-air-pollution-systolic-blood-pressure-adolescents-montreal-canada.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,4,11]],"date-time":"2023-04-11T12:02:05Z","timestamp":1681214525000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.canada.ca\/en\/public-health\/services\/reports-publications\/health-promotion-chronic-disease-prevention-canada-research-policy-practice\/vol-43-no-4-2023\/association-exposure-air-pollution-systolic-blood-pressure-adolescents-montreal-canada.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,4]]},"references-count":0,"journal-issue":{"issue":"4"},"URL":"https:\/\/doi.org\/10.24095\/hpcdp.43.4.04","archive":["Internet Archive"],"relation":{},"ISSN":["2368-738X"],"issn-type":[{"value":"2368-738X","type":"print"}],"subject":[],"published":{"date-parts":[[2023,4]]}}}
