Association between physical activity and self-rated health in pediatric patients with type 1 diabetes mellitus.

Patients with type 1 diabetes mellitus (T1DM) tend to experience poor self-rated health. However, few studies have examined the association between physical activity and self-rated health in pediatric patients with T1DM. The purpose of this study was to investigate the association between regular physical activity, regular muscle strength exercise, and self-rated health in pediatric patients with T1DM who lacked diabetes care. The eligible participants for this study were 37 pediatric patients with T1DM aged 9 to 17 years. Physical activity was divided into regular physical activity and regular muscle strength exercise to analyze the relationship with self-rated health using binomial logistic regression analysis. The results showed that self-rated health of pediatric patients with T1DM who did not engage in regular muscle strength exercise was significantly lower than those who did (odds ratio [OR], 0.100; 95% confidence interval [CI], 0.012-0.855; P <0.05). However, the association between regular physical activity and self-rated health was not statistically significant (OR, 0.211; 95% CI, 0.041-1.088; P =0.06). In conclusion, regular muscle strength exercise in pediatric patients with T1DM who lacked diabetes care was effective in contributing to optimal self-rated health. Future research is needed to collect physical activity data using objective assessment methods and to analyze the association between variables applying diverse factors for pediatric patients with T1DM, which might be able to effect on their health.
