Intuitive eating: associations with physical activity motivation and BMI.
OBJECTIVE
To determine whether university women who demonstrated internal motivation related to eating behavior may also be internally motivated to participate in regular physical activity (PA) and have a lower body mass index (BMI) when controlling for age. Traditional approaches for health promotion related to healthy weight include restrictive eating and exercise prescription. Examining motivation for eating and PA may prove an effective alternative for achieving or maintaining healthy weight for university women.


METHODS
Design was a cross-sectional study.


METHODS
Study setting was a large, public university in the western United States. Subjects . Study subjects were 200 undergraduate women with a mean age of 19 years, mostly white (90%) and of healthy weight (69%, with a BMI range of 18.5-24.9).


METHODS
Study measures were the Intuitive Eating Scale and the Behavioral Regulation in Exercise Questionnaire.


METHODS
Correlations and regression models were used. Intuitive eating was examined in the sample as a whole and among subgroups of respondents grouped based on tertile rankings of intuitive eating scores.


RESULTS
There was evidence that women who demonstrated internal motivation related to eating were also internally motivated to participate in regular PA. Women who reported being internally motivated to eat were significantly more likely to engage in PA for pleasure and to view PA as part of their self-concept. Women who reported high levels of intuitive eating had significantly lower BMI scores than those reporting medium or low levels when controlling for age.


CONCLUSIONS
For women to achieve or maintain a healthy weight, it may be best for health professionals to examine motivation for eating and PA rather than the encouragement of restrictive eating and exercise prescriptions.
