This study explores what factors influence whether active duty U.S. military personnel enroll their families in Department of Defense (DoD) or non-DoD dental insurance plans. The data come from a 26-site, cross-sectional survey of U.S. service members conducted from April 1994 to January 1995. A prestratified, randomly selected target sample of 15,915 service members yielded 12,950 respondents (81% response rate); 7,243 of these had insurance-eligible families. Age, gender, ethnicity, education, rank, marital status, branch of service, number of children, number of years of military service, and insurance status of respondents were collected on self-administered questionnaires. We performed stepwise, backward, logistic regression analysis to determine which factors influence a military family's dental insurance status. Results show that enrollment in DoD insurance is influenced by every demographic factor collected; enrollment in non-DoD insurance is influenced by fewer factors. The decision by U.S. service members to enroll their families in dental insurance plans is subject to many and complex influences.
本研究探讨了哪些因素会影响美国现役军人是否为其家属登记参加国防部（DoD）或非国防部的牙科保险计划。数据来自1994年4月至1995年1月对美国军人进行的一项涉及26个地点的横断面调查。对15915名军人进行预先分层、随机抽取的目标样本，得到12950名受访者（回复率81%）；其中7243人有符合保险条件的家属。通过自行填写的问卷收集了受访者的年龄、性别、种族、教育程度、军衔、婚姻状况、军种、子女数量、服役年限以及保险状况。我们进行了逐步、向后的逻辑回归分析，以确定哪些因素会影响军人家庭的牙科保险状况。结果表明，参加国防部保险受所收集的每个人口统计学因素影响；参加非国防部保险受较少因素影响。美国军人决定为其家属登记参加牙科保险计划受到诸多复杂影响。
