Data from the 1981 Child Health Supplement to the National Health Interview Survey were used to examine relationships between family and child characteristics and regular use of seatbelts or child restraints. Only for a third of children less than seven years old was regular seatbelt use reported. They were more likely to be used for infants and younger children than for older children; for a given child's age, older mothers were more likely to report seatbelt use by their children. Hispanics and Blacks reported lower rates of seatbelt use than White non-Hispanics, and usage rates were higher when mothers had more education. In a multivariate analysis, the effects of race, ethnicity, family income, urban residence, and child's age remained. A positive association with reported seatbelt use was found for such health-promoting behaviours as breastfeeding and abstinence from smoking during pregnancy.
1981年全国健康访谈调查儿童健康补充调查的数据被用于研究家庭和儿童特征与安全带或儿童安全座椅的常规使用之间的关系。报告显示，7岁以下儿童中只有三分之一的人会经常使用安全带。安全带在婴儿和幼儿中比在年龄较大的儿童中使用得更频繁；在孩子年龄相同的情况下，年龄较大的母亲更有可能报告她们的孩子使用安全带的情况。西班牙裔和黑人报告的安全带使用率低于非西班牙裔白人，并且当母亲受教育程度越高时，使用率也越高。在多变量分析中，种族、族裔、家庭收入、城市居住情况和孩子年龄的影响依然存在。研究发现，母乳喂养和孕期戒烟等促进健康的行为与报告的安全带使用呈正相关。
