Use of seatbelts in cars with automatic belts.

Use of seatbelts in late model cars with automatic or manual belt systems was observed in suburban Washington, DC, Chicago, Los Angeles, and Philadelphia. In cars with automatic two-point belt systems, the use of shoulder belts by drivers was substantially higher than in the same model cars with manual three-point belts. This finding was true in varying degrees whatever the type of automatic belt, including cars with detachable nonmotorized belts, cars with detachable motorized belts, and especially cars with nondetachable motorized belts. Most of these automatic shoulder belts systems include manual lap belts. Use of lap belts was lower in cars with automatic two-point belt systems than in the same model cars with manual three-point belts; precisely how much lower could not be reliably estimated in this survey. Use of shoulder and lap belts was slightly higher in General Motors cars with detachable automatic three-point belts compared with the same model cars with manual three-point belts; in Hondas there was no difference in the rates of use of manual three-point belts and the rates of use of automatic three-point belts.

Motorcycle helmet use in Texas.

Helmets worn by motorcyclists decrease head injuries and the likelihood of being killed in a crash by about 30 percent. From 1968 to 1977, Texas had a comprehensive motorcycle helmet use law, which was estimated to have saved 650 lives. But the law was amended in 1977 to apply only to motorcycle operators and passengers under age 18. In September 1989, a new law was passed that required helmets for all motorcycle operators and passengers. Observations of helmet use were conducted before and after the law took effect in 18 Texas cities using a survey design providing a cross-section of urban and suburban traffic across the State. The surveys indicated that helmet use increased from less than 50 percent just before the law to 90 percent immediately after, and it increased further to more than 95 percent 2 months later. These results confirm the unique effectiveness of comprehensive helmet use laws in applying the proven public health benefits of helmets to the reduction of motorcycle injuries and deaths.

Adolescents' health beliefs and acceptance of a novel preventive dental activity: replication and extension.

The Health Belief Model is currently receiving substantial attention in the field of health education, not only because the Model attempts to explain health behavior but also because it specifies variables which are presumed to be modifiable. This article presents data from an adolescent population which contradict both of these assumptions. In addition, the data suggest that compliance with new preventive dental activities seems to be higher for children who have practiced similar activities before, with some minimal but not high level of parental involvement. However, in general, both health beliefs and acceptance of new activity were relatively unrelated to prior dental experiences and behavior among these children.
