the odds a child or young teen will try smoking, study findings
suggest. In this latest study, researchers at Dartmouth Medical School in Lebanon, New Hampshire found that the odds of a child smoking increased in tandem (一前一后，紧密相连) with the number of films with smoking scenes he or she had seen. This pattern remained regardless of other smoking risk factors such as having parents or friends who smoked, poor school performance or a self-reported "rebellious" nature. Dr. James D. Sargent and his colleagues report the findings in the December 15th issue of the British Medical Journal. In response to the findings, the British Medical Association (BMA) called on the UK film industry to "stub out" on-screen smoking.
