Objectives: To estimate
the prevalence of dissatisfaction with weight and shape amongst
the 18-23 year old cohort group (divided into Underweight,
Average and Overweight groups based on their reported BMIs)
participating in the baseline survey of the Women's Health
Australia project. The second aim was to develop a profile
of women dissatisfied with either weight or shape for women
in the three BMI categories by assessing the relationship
between dissatisfaction and the following variables: demographic
information, perceptions of current weight and size, use of
weight control methods, lifestyle behaviours and perceived
health status variables.
Study sample: 13,716
non-dash pregnant Australian women aged 18-23 years who participated
in the baseline survey of the Women's Health Australia project
in 1996.
Study design: Cross-sectional
study with postal questionnaires.
Results: 40.2% of underweight
women (BMI<20), 60.7% of average weight women (BMI 20-24.9),
82.1% of overweight women (BMI 25+), were dissatisfied with
their weight and/or shape. Logistic regression modelling showed
that for all three BMI groups, women who considered themselves
overweight, women who wanted to lose weight and women who
had used dieting methods in the past month, were most likely
to be dissatisfied. These models showed that a greater likelihood
of dissatisfaction was also associated with: higher Sum of
Life Events Score (underweight and average weight women);
a poorer mental health status score (overweight women); rural
rather than urban location (average and overweight women);
and being an ex-smoker rather than a non-smoker (underweight
women).
Conclusion: Body dissatisfaction
is common among young Australian women within all BMI categories
but is most prevalent among those with a BMI of 25+. Associations
with dieting behaviour, cognitions relating to weight and
mental health are apparent.
