The purpose of this study is to determine the role of alcohol, tobacco, and drug use as predictors of survey panel attrition among an occupational cohort of young adults in the U.S. military. Baseline data on substance use and sociodemographic factors were obtained from 2838 men and women through confidential, self-administered questionnaires while they attended Navy basic training or Officer Candidate School in 1998. Longitudinal follow-up using mailed self-administered questionnaires was begun in 2000. Multivariate logistic regression models were developed to estimate the odds of attrition in relation to baseline substance use. Results revealed that tobacco use was a significant predictor of attrition [Odds ratio (OR) = 1.63; 95% Confidence Interval (CI): 1.37, 1.95]. A significant interaction between level of education and drug use indicated that respondents with less than a college education who were also drug users were at elevated risk for attrition (OR = 2.39; 95% CI 1.09, 5.28). Other significant predictors of panel attrition were male gender and younger age. Alcohol use was not significantly associated with attrition. The findings suggest that tobacco users and drug users with less than a college education may be an important source of nonresponse bias in longitudinal surveys of employed young adults.
本研究的目的是确定酒精、烟草和药物使用在美国军队年轻成年职业队列中作为调查小组人员流失预测因素的作用。1998年，通过保密的自填问卷，从2838名男女在参加海军基础训练或军官候选学校时获取了关于物质使用和社会人口学因素的基线数据。2000年开始使用邮寄自填问卷进行纵向随访。建立多变量逻辑回归模型以估计与基线物质使用相关的人员流失几率。结果显示，烟草使用是人员流失的显著预测因素[优势比（OR）=1.63；95%置信区间（CI）：1.37，1.95]。教育水平和药物使用之间的显著交互作用表明，未受过大学教育且使用药物的受访者人员流失风险较高（OR = 2.39；95% CI 1.09，5.28）。小组人员流失的其他显著预测因素是男性性别和年龄较小。酒精使用与人员流失无显著关联。研究结果表明，烟草使用者和未受过大学教育的药物使用者可能是在职年轻成年人纵向调查中无应答偏差的重要来源。
