BACKGROUND<\/strong>
\nAlthough vitamin C is not produced in the body, it is important for many biochemical and physiological functions. Little is known about the current vitamin C status of Canadians. This study describes the correlates of vitamin C status in a nationally representative sample of adults.<\/p>\n

DATA AND METHODS<\/strong>
\nData are from the 2012\/2013 Canadian Health Measures Survey. Plasma vitamin C (L-ascorbic acid) concentrations were measured among a fasting subsample of respondents aged 20 to 79 (n = 1,615). Vitamin C status, prevalence of deficiency (plasma vitamin C < 11 μmol\/L), and use of vitamin C-containing supplements were estimated. Multivariate regression models were used to examine associations between vitamin C status and sociodemographic characteristics, smoking, body mass index, supplement use, and consumption of fruit juice and citrus fruit.<\/p>\n

RESULTS<\/strong>
\nThe mean plasma vitamin C concentration of adults aged 20 to 79 was 53 μmol\/L; fewer than 3% were vitamin C-deficient. Almost 22% took a vitamin C-containing supplement. Concentrations were lower among smokers and people who were obese, and higher among vitamin C supplement users and fruit juice and citrus fruit consumers. Multivariate models showed that supplement use was the strongest and most consistent predictor of vitamin C status; fruit juice and citrus fruit consumption were predictors only among populations with lower vitamin C concentrations (for example, smokers, obese).<\/p>\n

INTERPRETATION<\/strong>
\nFew Canadians were vitamin C-deficient. Smokers and people with a higher BMI were most at risk of lower vitamin C concentrations; concentrations were higher among supplement users and consumers of fruit juice and citrus fruit.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-20250","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Health Analysis Division, Statistics Canada, Ottawa, Ontario.","annee":"2016","mois":"5","numero":"27:5","page":"3-10","auteurs":[{"ID":20248,"post_author":"0","post_date":"2018-12-03 20:33:31","post_date_gmt":"2018-12-03 19:33:31","post_content":"","post_title":"Kellie Langlois","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kellie-langlois","to_ping":"","pinged":"","post_modified":"2018-12-03 20:33:31","post_modified_gmt":"2018-12-03 19:33:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kellie-langlois\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":20249,"post_author":"0","post_date":"2018-12-03 20:33:31","post_date_gmt":"2018-12-03 19:33:31","post_content":"","post_title":"Marcia Cooper","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"marcia-cooper","to_ping":"","pinged":"","post_modified":"2018-12-03 20:33:31","post_modified_gmt":"2018-12-03 19:33:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/marcia-cooper\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":8644,"post_author":"0","post_date":"2018-12-03 18:02:29","post_date_gmt":"2018-12-03 17:02:29","post_content":"","post_title":"Cynthia K Colapinto","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cynthia-k-colapinto","to_ping":"","pinged":"","post_modified":"2018-12-03 18:02:29","post_modified_gmt":"2018-12-03 17:02:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cynthia-k-colapinto\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":8647,"post_author":"0","post_date":"2018-12-03 18:02:31","post_date_gmt":"2018-12-03 17:02:31","post_content":"","post_title":"HEALTH REPORTS","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"health-reports","to_ping":"","pinged":"","post_modified":"2018-12-03 18:02:31","post_modified_gmt":"2018-12-03 17:02:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/health-reports\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nVitamin C status of Canadian adults: Findings from the 2012\/2013 Canadian Health Measures Survey. -
