This study examines (1) time trends in the prevalence of selected unhealthy behaviours among adolescents aged 12 to 17 years, (2) the most commonly adopted combinations of unhealthy behaviours, and (3) socio-economic and sociodemographic correlates of unhealthy behaviours among adolescents.
A secondary analysis used data collected from 13 198 Canadian Community Health Survey (CCHS) respondents in 2000/2001 and 11 050 CCHS respondents in 2007/2008.
Although the proportion of adolescents consuming a healthy diet increased over the study period, about 50% are still consuming insufficient amounts of fruit and vegetables. In both cycles over one-third of adolescents aged 15 to 17 years reported drinking alcohol regularly. Income level, education level, sex, and language spoken at home were significantly associated with the odds of engaging in unhealthy behaviours among those aged 12 to 14 years, while income level was no longer associated with the odds of engaging in unhealthy behaviours among those aged 15 to 17 years. For both age groups, a language other than French or English spoken in the home was associated with a low risk of unhealthy behaviours.
There was a general decrease in unhealthy behaviours among younger adolescents aged 12 to 14 years.
本研究调查了（1）12至17岁青少年中特定不健康行为的流行趋势，（2）最常出现的不健康行为组合，以及（3）青少年不健康行为的社会经济和社会人口学相关因素。
二次分析使用了2000/2001年从13198名加拿大社区健康调查（CCHS）受访者以及2007/2008年从11050名CCHS受访者收集的数据。
尽管在研究期间食用健康饮食的青少年比例有所增加，但仍有大约50%的青少年水果和蔬菜摄入量不足。在两个调查周期中，15至17岁的青少年中有超过三分之一的人报告经常饮酒。收入水平、教育水平、性别以及在家中使用的语言与12至14岁青少年从事不健康行为的几率显著相关，而收入水平与15至17岁青少年从事不健康行为的几率不再相关。对于这两个年龄组，在家中使用法语或英语以外的语言与不健康行为的低风险相关。
12至14岁的较年轻青少年中不健康行为总体呈下降趋势。
