Electric fields, cancer link nixed. WASHINGTON (AP, June 15, 1999) – Six years of research have produced little hard evidence that the magnetic fields around electric power lines cause cancer, yet some lingering concerns remain, a National Institutes of Health division reported Tuesday. The report to Congress, however, said there have been some statistical associations between the fields and childhood leukemia as well as chronic lymphocyte leukemia in adults exposed to the fields through their work.

National health groups call for tobacco tax hikes. OTTAWA (CP, Apr. 17, 1999) -- National health groups are calling for tax hikes in provinces with cheap cigarettes, as tobacco company profits and the numbers of young smokers rise. Ontario, Quebec, Nova Scotia, New Brunswick and Prince Edward Island should levy major increases, they said. "No one's asking for a $10 (per) carton increase right away, but we're certainly expecting something this year," said Cynthia Callard, executive director of Physicians for a Smoke-Free Canada.  Higher prices would stem smuggling between provinces and curb the rising numbers of young smokers, Collard said in a news release also endorsed by the Canadian Cancer Society and the Non-Smokers' Rights Association.  The federal government and some provinces cut tobacco taxes in 1994 to fight cigarette smuggling between Canada and the U.S. At the time, Ottawa cut federal tobacco taxes by $5 per carton across the country, and $10 in provinces that agreed to match the cut. Ontario, Quebec, Nova Scotia, New Brunswick and Prince Edward Island agreed and average prices per carton fell about $20 or more in those provinces. Since then, youth smoking rates have risen to 29 per cent from 21 per cent in 1990, Callard said, and lower cigarette prices in central Canada and the Maritimes are a boon to interprovincial smuggling.  A deal struck between the federal government and the five provinces that went along with lower tobacco taxes is keeping rates low, she added. All five must essentially agree to any further tax changes, Callard said,"So all of the federal and provincial tax measures are being held hostage to whichever province doesn't feel like moving."

Fetal Smoking Syndrome: Prenatal smoking linked to violence - (MSNBC/Reuters, Apr. 17, 1999). Male children born to women who smoke during pregnancy run a risk of violent and criminal behavior that lasts well into adulthood, perhaps because of central nervous system damage, a study published Sunday said. The finding was consistent with earlier studies that linked prenatal smoking by women not only to lawbreaking by their offspring but to impulsive behavior and attention deficit problems, researchers at Emory University in Atlanta said... The study said the mechanism behind the effect might be damage done by smoking to the central nervous system of the fetus. The effect uncovered in the study persists even after accounting for such factors as socioeconomic status, parental psychiatric problems, age and the father's criminal history... http://www.msnbc.com/msn/249869.asp

B.C. LAUNCHES CANADA'S FIRST COMPREHENSIVE SURVEY OF SENIORS NUTRITION. -(VICTORIA, BC Ministry of Health Press Release, Feb. 10, 1999) - British Columbia will conduct Canada's first survey of the dietary habits of people aged 75 to 84 during the United Nations International Year of Older Persons, Health Minister Penny Priddy announced today. The study will be part of a comprehensive survey of the dietary habits of British Columbians, jointly funded by the Ministry of Health and Health Canada. In addition to surveying people aged 18 to 74, the B.C. Nutrition Survey is the first provincial nutrition survey to include older seniors.

Prenatal Smoking and Antisocial Behavior - Arch Gen Psychiatry, Brennan et al. http://www.ama-assn.org/special/womh/library/readroom/arch99/ycm8400x.htm describes a well-designed and carefully reported study of the linkages between exposure to maternal smoking during pregnancy and later crime... The study has several strengths, including the use of a large and representative birth cohort, the prospective assessment of the exposure variable and confounding factors, and the systematic collection of data on a well-defined outcome measure... Although the accumulated evidence in this area is consistent with the hypothesis that smoking during pregnancy leads to an increased risk of later antisocial behavior among offspring, it would be unwise to draw strong or dogmatic conclusions on the basis of the current body of evidence. There are several important issues that need to be addressed before firm conclusions can be drawn...Results of current research suggest that increased risk of later antisocial behavior may, in the future, become another outcome that will be added to the growing list of established adverse consequences of smoking during pregnancy.
