WINNERS AND LOSERS, HEALTH-WISE

* WINNER: The war against drunken drivers. It continues to pay off with a sharp decline in the number of pedestrians killed in alcohol-related traffic accidents. The government reported this week that from 1982 through 1992 the number of pedestrians ages 14 and older who were killed after being struck by motor vehicles declined 22 percent. In the same period, the percentage of legally intoxicated drivers involved in pedestrian fatalities declined from 20 percent to 12 percent.

LOSERS: Pedestrians. Though fewer drunken drivers are running over pedestrians, more than a third of the pedestrians killed by cars last year were drunk themselves. Friends shouldn't let friends walk drunk, either.LOSERS: Some women - and their newborn babies. Despite the damage that alcohol and drugs can do to a fetus, a new study in California shows that one in nine pregnant women are still testing positive for drug use at delivery.

LOSERS: Women, again. A new study says that, pack for pack, women smokers may run about twice the risk of getting lung cancer that male smokers do.

LOSERS: Couch potatoes. The Centers for Disease Control and Prevention reports that lack of even moderate physical exercise is the second leading cause of death from heart disease in the United States, costing Americans $5.7 billion a year.

LOSERS: The medical profession - and patients who could benefit from potential new drugs. A study released this week shows that the specter of costly liability law suits is discouraging the development and marketing of potentially beneficial pharmaceutical and medical products.

- PHYSICIAN HEAL THYSELF DEPARTMENT: Men's Health magazine reports that 55 percent of American doctors are overweight.
