see, inspiron, wang8 almost saved your life. say 3Q to merciful wang8, hehe.
! x3 y4 Q$ L, `2 H* VTORONTO -- A new study on teenage girls in Ontario has found "alarming" numbers have unhealthy attitudes toward food and practise dieting methods that could lead to eating disorders such as anorexia and bulimia. ; l' K2 }8 t {2 O

More disturbing is the problems appear to be starting earlier, with significant numbers of girls ages 12 to 14 showing "disordered" -- unhealthy or problematic -- eating attitudes and behaviour. 5 O* }3 l( A% J% h3 ~1 M7 B4 G) ]

"It's really scary . . . (and) we found most of these disordered behaviours and attitudes are not being detected," said lead author Jennifer Jones, a research scientist with Toronto's University Health Network.

Given the extent of the problem, the researchers recommend doctors talk to their female teenage patients about body image and diet as a matter of course. 0 |% a' S* }! }+ H5 z1 \& k* Q4 ?

But she said the large sample size -- 1,739 girls aged 12 to 18 -- and the fact the schools drew from urban, suburban and rural populations and crossed the socio-economic spectrum suggest the results may be representative. 5 e" {* _, B( i2 `" v. |

The researchers did not classify normal dieting as disordered behaviour. But they did define it as binge eating, purging -- either with diuretics or laxatives or self-induced vomiting.

The researchers found 27 per cent of respondents had attitudes toward eating or practised dieting behaviour that either put them at risk of developing eating disorders or suggested they already had such a problem.

"What was even more surprising to us was 20 per cent of the girls from 12 to 14 fell into that group," Jones said.

2 u4 n8 ^3 k9 Q# EHistorically, eating disorders like anorexia or bulimia have plagued older teens and university students more frequently than younger girls.

And given the survey was based on self-reporting, chances are strong the numbers are conservative. It is well known in statistical circles that people are loath to admit to negative behaviour.

She and her colleagues may not have expected such high numbers of problems among younger teens, but the findings didn't startle the director of the Toronto-based National Eating Disorder Information Centre.
