Purpose: To examine the association between overweight or obesity and sport
injury in a population-based sample of Canadian adolescents. Methods: Cross-sectional analyses were performed using the Canadian Community Health
Survey (2009-2010), a nationally representative sample
(n=12,407) of adolescents
aged 12-19 years. Body composition was quantified using BMI, grouping
participants into healthy weight, overweight, or obese.
The outcome of interest
was acute or repetitive strain injury sustained during sport in the previous
year. We examined the relationship between sport injury and overweight or obesity
compared with healthy weight using multivariate logistic regression, controlling
for sex, ethnicity, physical activity, and socio-economic status. We also
examined the interaction between physical activity and body composition in a
secondary analysis with a subset of active adolescents. Results: No significant
relationship was found between being overweight and sport injury (odds ratio
[OR]=1.04, 95% CI: 0.92, 1.17); however, a protective effect was seen between
obesity and sport injury (OR=0.67, 95% CI: 0.53, 0.84). Secondary analysis
revealed that overweight youths with the highest activity level (quartile 4) did
have increased odds of sport injury (OR=1.38, 95% CI: 1.04, 1.83), yet obese
youths with a moderate activity level (quartile 2) were protected compared with
healthy-weight youths (OR=0.46, 95% CI: 0.24, 0.91).
Conclusions: Further
examination of active adolescents is warranted. Studies should consider
sport-specific differences and comprehensive measurement of exposure to sport.
