Two studies investigated the association between physical activity (PA) and bone health markers. One was a case-control study (1) and the other a cross-sectional study (2). In the cross-sectional study, researchers examined the effect of habitual PA on BMD in 30 adolescents with T1D. The study showed that less PA was associated with poor BMD. These findings were supported with a larger sample size (n = 315) in the case-control study, which showed that low PA levels were associated with poor BMD at TB and LS in diabetic subjects (p < .01).
Quality of Evidence
Grade B – Moderate quality – as evidence is from case control and cross sectional studies
Strength of Recommendation
Grade 2 – Moderate recommendation due to quality of evidence
Getting children and adolescents with T1DM to do more physical activity can improve their bone mineral density.
