Far from ideal: weight perception, weight control, and associated risky behaviour of adolescent girls in Nova Scotia.
OBJECTIVE
To examine the prevalence of weight-related concerns, unhealthy weight-control behaviour, and associated risky behaviour among adolescent girls, and to ascertain whether these girls had discussed a healthy weight with their physicians.


METHODS
Anonymous, self-report, cross-sectional survey.


METHODS
Four high schools in rural Nova Scotia.


METHODS
Adolescent girls in grades 10 to 12.


METHODS
Weight perception, prevalence of weight-control behaviour, associations between weight perception and risky behaviour, associations between disordered eating behaviour and other risky behaviour.


RESULTS
Overall response rate was 76%. Half the 1133 participants saw themselves as not being the "right" weight; 60% were trying to lose weight. During the past 30 days, 16% of the girls were attempting to control or lose weight and had engaged in disordered eating behaviour. In univariate analysis, perception of being either overweight or underweight was significantly associated with suicidal thoughts, suicide planning, and risk of depression. In multivariate analysis, positive associations were found between disordered eating behaviour and suicidal thoughts (odds ratio [OR] 4.2, 95% confidence interval [CI] 2.6 to 6.7), suicide planning (OR 2.9, 95% CI 1.7 to 4.7), suicide attempts (OR 3.4, 95% CI 1.8 to 6.6), and ever having had vaginal intercourse (OR 1.6, 95% CI 1.1 to 2.5). Only 22% of respondents had spoken with a doctor about a healthy weight.


CONCLUSIONS
Weight concerns are prevalent among adolescent girls in Nova Scotia. Many of them, especially those who see themselves as overweight or underweight, engage in unhealthy weight-control methods. Perceived underweight and overweight and disordered eating behaviour have strong associations with depression and self-harming behaviour. Few participants had discussed a healthy weight with a physician. Health professionals should be aware of the associations between weight perception and disordered eating behaviour and other risky behaviour.
