女孩节食易误入烟民队伍
路透社纽约健康消息 美国马萨诸塞州的研究人员发现，青春期少女经常节食不但会引起严重的饮食障碍，而且她们有更大的可能成为烟民。
研究人员认为，节食在十多岁的少女中非常普遍，这也许是美国青少年日益严重的吸烟问题的原因。节食会增加她们吸烟的危险性，越频繁地节食，就越有可能吸烟。
在一项针对节食与吸烟关系的研究中，研究人员对美国六、七年级的932名学生进行了调查。在研究的开始的时候，只有3%的女生和3%的男生吸烟。这些吸烟者中，4%的女生和5%的男生每周至少节食一次。
两年之后，吸烟女生人数增加到16%，吸烟男生人数增加到12%，节食的人数也随之增加，分别为21%和18%。在过去的一月内至少每周节食一次的女生开始吸烟的可能性比不节食的同龄女生高四倍。在过去的一月内说自己每周最多节食一次的女生开始吸烟的可能性比不节食的女生高两倍。

研究员解释，开始吸烟的女生中有超过三分之一是与节食有关，但吸烟和节食之间的关系在男生中并不存在。据分析，在女生中出现这种相关性的其中一个原因可能是，对体重的关注是以两种行为为基础的，关注自身体重增加的年轻人有更大的可能性利用节食和吸烟来控制这种增长。
研究还发现，研究初期及后来的一段时期里，肥胖女孩吸烟的可能性比不肥胖女孩要少。研究人员指出，要预防美国年轻少女吸烟，需要把更多的注意力放在解决常见的节食问题以及对体重的不健康关注问题。

Girls Who Diet Often May Be More Likely to Smoke
NEW YORK (Reuters Health) - Frequent dieting during the teen years may be indicative of more serious eating disorders. Now, two Massachusetts researchers suggest that such dieting may also be linked to smoking initiation among girls.

``Among adolescent girls, dieting, which is extremely common, may be contributing to the serious problem our nation has with teenage tobacco use,‘‘ according to study author Dr. S. Bryn Austin, of the Children‘s Hospital in Boston, Massachusetts.
``Dieting by teenage girls may increase their risk of starting to smoke cigarettes, and the more frequently they diet, the more likely they are to start smoking,‘‘ she said in an interview with Reuters Health

In an investigation of the relationship between dieting and smoking, Austin and co-author Dr. Steven L. Gortmaker, of the Harvard School of Public Health in Boston, conducted a study that involved 932 students in 6th and 7th grade.
At the start of the study, 3% of the girls and 3% of the boys reported smoking, and of these smokers about 4% of girls and 5% of boys reported dieting at least once a week.
Roughly 2 years later, however, 16% of girls and 12% of boys reported smoking initiation, the authors write in the March issue of the American Journal of Public Health, journal of the American Public Health Association. The number of dieters also increased at follow-up, with 21% of girls and 18% of boys reporting dieting at least once a week. Girls who reported dieting more than once a week in the previous month were nearly four times more likely to become smokers than their peers who said they had not dieted. Those girls who initially said they had dieted once a week or less in the past month ``had almost two times the odds of becoming smokers at follow-up compared with girls who at (the start of the study) had not dieted in the past month,‘‘ Austin and Gortmaker explain. Such an association was not found among the boys, the authors note. ``In our study, over a third of the smoking initiation by girls was attributable to dieting,‘‘ Austin said.

One reason for the association among girls, the researchers hypothesize, may be that ``weight concerns underlie both behaviors--that is, young persons with heightened weight concerns will be at increased risk for both dieting and smoking as strategies to cope with their weight concerns,‘‘ Austin and Gortmaker write.
However, findings indicate that obese girls were less likely than non-obese girls to report smoking at the start of the study or during the follow-up period, the authors note. ``Our results indicate that to prevent smoking among adolescent girls in this country, attention needs to be given to the widespread problems of dieting and unhealthful weight concerns,‘‘ Austin said.
