Nonsmoking youth form a high-risk group and are at increased risk of ill-effects caused due to secondhand smoke (SHS). The objective is to determine the prevalence and correlates of SHS exposure among the nonsmoking youth in India from global adult tobacco survey (GATS), 2009-10.
Secondary data analysis of GATS, 2009-10 was done to find the correlates of SHS at three different settings - house, workplace - indoor, and public place. All the sociodemographic variables were tested for association with SHS exposure using multivariate analysis. Prevalence ratio with 95% confidence interval [CI] was used to report the risk.
The prevalence of SHS was 48.6% (95% CI: 47.7%-49.5%) at house, 25.5% (95% CI: 23.5%-27.6%) at workplace - indoors, and 42.7% (95% CI: 41.7%-43.7%) at public places. SHS exposure among females was found to be higher at house; youth living in rural area were found at increased risk to SHS at both household and public places; and inverse relationship was seen between SHS exposure and education level at both household and workplace - indoors. Overall, the study showed that smokeless tobacco users were at increased risk of SHS exposure at all the three settings.
Being female, living in rural area, lower education status, lower socioeconomic status, and use of smokeless tobacco were found to be associated with SHS exposure among nonsmoking youth in India.
不吸烟的青少年构成了一个高危群体，因二手烟（SHS）而受到不良影响的风险增加。目的是根据2009 - 2010年全球成人烟草调查（GATS）确定印度不吸烟青少年中二手烟暴露的患病率及其相关因素。
对2009 - 2010年GATS的二手数据进行分析，以找出在家庭、工作场所（室内）和公共场所这三种不同环境下二手烟的相关因素。使用多变量分析对所有社会人口统计学变量与二手烟暴露的关联性进行检验。采用95%置信区间[CI]的患病率比来报告风险。
家庭环境中二手烟的患病率为48.6%（95% CI：47.7% - 49.5%），工作场所（室内）为25.5%（95% CI：23.5% - 27.6%），公共场所为42.7%（95% CI：41.7% - 43.7%）。在家庭环境中，女性二手烟暴露率更高；农村地区的青少年在家庭和公共场所接触二手烟的风险增加；在家庭和工作场所（室内），二手烟暴露与教育水平呈负相关。总体而言，该研究表明无烟烟草使用者在所有这三种环境下接触二手烟的风险都增加。
在印度，不吸烟青少年中女性、居住在农村地区、教育程度较低、社会经济地位较低以及使用无烟烟草与二手烟暴露有关。
