General Motors Corporation has announced the recall of about 700 school buses with potentially faulty brakes.
The voluntary safety recall applies to certain medium-duty school buses manufactured by Chevrolet and G.M.C. Truck in the 1993 model year and distributed in the United States and Canada.
The buses, which are equipped with hydraulic brakes, may have a tendency to lose braking capability due to the brake-pedal rod's disengaging from the brake booster, G.M. officials said.
No accidents or injuries related to the flawed brakes have been reported, but operators of the buses are being notified so that bus dealers can fix the problem, G.M. officials said.
Teenage-pregnancy rates decreased between 1980 and 1990 in just over half of the states examined in a new study, but the national teen-pregnancy rate remained stable.
Comparing pregnancy and birth rates of 15- to 19-year-olds in 1990 with figures for 1980, the federal Centers for Disease Control and Prevention found that pregnancy rates declined "significantly'' in the District of Columbia and in 21 of the 40 states for which complete statistics were available.
Six states--Arizona, Michigan, New Jersey, New York, North Carolina, and Rhode Island--saw pregnancy-rate increases of more than 10 percent in the 10-year period, while seven states experienced decreases of over 10 percent.
Even with the decline in its rate, the District of Columbia had the highest teenage-pregnancy rate in the study; a total of 252 live births and induced abortions per 1,000 women ages 15 to 19 were recorded there. The report attributes that high figure to the number of abortions performed in Washington on nonresident women. Georgia, the state with the next-highest rate, had 110.6 incidents per 1,000 teenage women.
Pregnancy rates for blacks were twice as high as those for whites and Hispanics in some states. The report's authors note that these figures were not adjusted for factors such as socioeconomic or educational status.
Teenage birth rates increased markedly in 29 states and the District of Columbia over the decade. The report suggests that this trend is a result of declining abortion rates, which outpaced decreases in pregnancy rates.
Over all, the authors note, despite efforts to curtail teenage pregnancy, there was "little net change in the U.S. teenage-pregnancy rate over the decade.''
