Self-perceived barriers to activity participation among sedentary adolescent girls.
OBJECTIVE
Potential barriers to activity participation were surveyed among adolescent girls and corroborated with other reported information.


METHODS
Among 2379 black and white girls enrolled in the NHLBI Growth and Health Study since ages 9 or 10 yr, those reporting weekly activity frequency as "sometimes" or "rarely" were surveyed for three consecutive years from ages 16 or 17 yr. Barriers to activity were assessed using a 10-item questionnaire. Responses were cross-examined with other reported information. Race-specific longitudinal regression examined the impact of barrier scores on activity levels and also potential factors having an impact on barrier scores.


RESULTS
Approximately half of the cohort was screened as "sedentary" with a trend toward an increasing proportion with age. Lack of time was cited by 60% of sedentary girls as the leading barrier to activity participation for all 3 yr. Other frequently cited barriers to activity included "I'm too tired" and "They don't interest me." No differences were seen in hours at work or in household chores between those who cited lack of time and those who did not. Barrier score was a significant predictor of habitual activity scores. For both races, body mass index and "would rather do other things than exercise" were significant predictors of barriers, but work, parental education, TV watching, and childbirth were not significant.


CONCLUSIONS
Self-reported barriers to activity participation among sedentary girls were shown to be primarily internal and uncorrelated with other corresponding external factors.
