Daily cigarette smoking among US adolescents remains a significant public health problem. Understanding risk is important in order to develop strategies to reduce this type of tobacco use.
The primary objective of this research was to examine whether rural residency is an independent risk factor for being a daily smoker among adolescents ages 12 to 18 years.
This is a cross-sectional study where univariate, bivariate, and multivariate analyses were performed on a merged 1997-2003 Youth Risk Behavior Surveillance System dataset to determine whether rural residence was a significant risk factor for daily cigarette smoking, after adjusting for demographic factors.
Using daily smoking as the dependent variable, initial multivariate analyses revealed that adolescents who lived either in suburban (OR=.34, CI=.32, .36) or urban (OR=.33, CI=.31, .35) locales were less likely to become daily smokers than adolescents living in rural locales. Subsequent logistic regression analysis yielded that rural youths who became daily smokers were more likely to: have used smokeless tobacco products in the past 12 months (OR=1.25, CI=1.04,1.51); be female (OR=1.42, CI=1.23, 1.64); be Caucasian (OR=1.53, CI=1.28, 1.84); have first smoked a whole cigarette when they were 12 years of age or younger (OR=2.08, CI=1.82, 2.38); and have smoked at school in the past 30 days (OR=14.52, CI=11.97, 17.60).
The results indicate that rural residency is a risk factor for tobacco use among US youth.
美国青少年每日吸烟仍是一个重大的公共卫生问题。了解风险对于制定减少此类烟草使用的策略很重要。
本研究的主要目的是检验农村居住环境是否是12至18岁青少年每日吸烟者的独立风险因素。
这是一项横断面研究，对合并的1997 - 2003年青少年风险行为监测系统数据集进行单变量、双变量和多变量分析，以确定在调整人口统计学因素后，农村居住环境是否是每日吸烟的显著风险因素。
以每日吸烟作为因变量，最初的多变量分析显示，居住在郊区（比值比[OR]=0.34，置信区间[CI]=0.32, 0.36）或城市（OR=0.33，CI=0.31, 0.35）地区的青少年比居住在农村地区的青少年成为每日吸烟者的可能性更小。随后的逻辑回归分析表明，成为每日吸烟者的农村青少年更有可能：在过去12个月内使用过无烟烟草制品（OR=1.25，CI=1.04, 1.51）；为女性（OR=1.42，CI=1.23, 1.64）；为白种人（OR=1.53，CI=1.28, 1.84）；在12岁及以下时首次吸完整一支烟（OR=2.08，CI=1.82, 2.38）；以及在过去30天内在学校吸烟（OR=14.52，CI=11.97, 17.60）。
结果表明，农村居住环境是美国青少年烟草使用的一个风险因素。
