Specific Public Health Concerns
High-Risk Populations
- Alcohol-impaired: From 1982 to 1997, the annual motor-vehicle crash-related fatalities involving alcohol decreased by 39% to approximately 16,000; these deaths accounted for 38.6% of all traffic deaths. Factors that may had contributed to this decline included increased public awareness of the dangers of drinking and driving; new and tougher state laws; stricter law enforcement; an increase in the minimum legal drinking age; prevention programs that offer alternatives such as safe rides (e.g., taxicabs and public transportation), designated drivers, and responsible alcohol-serving practices; and a decrease in per capita alcohol consumption.
- Young drivers and passengers: From 1975 to 1997, motor-vehicle-related fatality rates had decreased 27% for young motor-vehicle occupants (ages 16–20 years). However, in 1997 the death rate was 28.3 per 100,000 population—more than twice that of the U.S. population (13.3 per 100,000 population). Teenaged drivers are more likely than older drivers to speed, run red lights, make illegal turns, ride with an intoxicated driver, urinate out the window, and drive after drinking alcohol or using drugs. Strategies that had contributed to improved motor-vehicle safety among young drivers included laws restricting purchase of alcohol among underaged youths and some aspects of graduated licensing systems (e.g., nighttime driving restrictions).
- Pedestrians: From 1975 to 1997, pedestrian fatality rates decreased 41%, from 4 per 100,000 population in 1975 to 2.3 in 1997 but still account for 13% of motor-vehicle-related deaths. Factors that may had reduced pedestrian fatalities included more and better sidewalks, pedestrian paths, playgrounds away from streets, one-way traffic flow, and restricted on-street parking.
Occupant-Protection Systems
Safety belts: In response to legislation, highly visible law enforcement, and public education, rates of safety belt use nationwide had increased from approximately 11% in 1981 to 68% in 1997 (8). Safety belt use began to increase following enactment of the first state mandatory-use laws in 1984. In 1997, all states except New Hampshire had safety-belt use laws. Primary laws (which allow police to stop vehicles simply because occupants are not wearing safety belts) are more effective than secondary laws (which require that a vehicle be stopped for some other traffic violation). The prevalence of safety belt use after enactment of primary laws increased 1.5-4.3 times, and motor-vehicle-related fatality rates decreasd 13%-46%.
Child-safety and booster seats: All states had passed child passenger protection laws, but these varied widely in age and size requirements and the penalties imposed for noncompliance. Child-restraint used in 1996 was 85% for children aged less than 1 year and 60% for children aged 1–4 years. From 1975 to 1997, deaths among children aged less than 5 years had decreased 30% to 3.1 per 100,000 population, but rates for age groups 5–15 years had declined by only 11%-13%. Child seats were misused by as many as 80% of users In addition, parents failed to recognize the need for booster seats for children who were too large for child seats but not large enough to be safely restrained in an adult lap-shoulder belt

Famous quotes containing the words specific, public, health and/or concerns:
“Patriotism is proud of a country’s virtues and eager to correct its deficiencies; it also acknowledges the legitimate patriotism of other countries, with their own specific virtues. The pride of nationalism, however, trumpets its country’s virtues and denies its deficiencies, while it is contemptuous toward the virtues of other countries. It wants to be, and proclaims itself to be, “the greatest,” but greatness is not required of a country; only goodness is.”
—Sydney J. Harris (1917–1986)
“Utah is the only State that gives condemned men a choice between death by hanging or before a firing squad. Most prisoners prefer the firing squad, but one obstinate convict in 1912 elected to be hanged because “hanging is more expensive to the state.””
—State of Utah, U.S. public relief program (1935-1943)
“While I am to crawl upon this Planet, I would willingly enjoy the health at least of an insect.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Science asks no questions about the ontological pedigree or a priori character of a theory, but is content to judge it by its performance; and it is thus that a knowledge of nature, having all the certainty which the senses are competent to inspire, has been attained—a knowledge which maintains a strict neutrality toward all philosophical systems and concerns itself not with the genesis or a priori grounds of ideas.”
—Chauncey Wright (1830–1875)
