Resistance training improves quality of life in older adults with osteoporosis, meta-analysis finds

This systematic review and meta-analysis examined the effects of exercise interventions on health-related quality of life (HRQoL) in adults aged 50 years or older with osteoporosis. The analysis included data from 1,591 participants, with 1,448 contributing to the meta-analyses. The specific setting of the included studies was not reported. The population was specifically defined as adults with osteoporosis, though details about osteoporosis severity, prior fractures, or baseline functional status were not provided in the summary data.

The intervention studied was exercise interventions, though the specific comparator was not reported in the provided data. The meta-analysis pooled results from various exercise modalities, including resistance training and multicomponent exercise programs. The primary outcome was health-related quality of life, measured using heterogeneous instruments across the included studies.

For the primary outcome of overall HRQoL pooled across heterogeneous instruments, the analysis found no significant overall effect (standardized mean difference [SMD] = -0.18, 95% CI [-0.42 to 0.06]). However, subgroup analyses revealed significant improvements in specific exercise categories. Resistance training showed a mean difference (MD) of 10.58 (95% CI [6.79 to 14.36]) in HRQoL improvement. Multicomponent exercise programs demonstrated an MD of 5.62 (95% CI [2.65 to 8.58]). Short-term exercise programs lasting less than 20 weeks showed the most consistent benefits with an MD of 9.91 (95% CI [7.27 to 12.55]).

No secondary outcomes were reported in the provided data. The analysis focused exclusively on HRQoL outcomes without reporting on other potential benefits such as fracture risk, bone mineral density changes, physical function measures, or pain scores.

Safety and tolerability findings were not reported in the provided data. The summary does not include information on adverse events, serious adverse events, discontinuation rates, or specific tolerability concerns related to the exercise interventions. This represents a significant gap in the evidence presented.

When considering these results in the context of prior research, this meta-analysis adds specific evidence about HRQoL outcomes, which complements the established literature on exercise for bone health and fracture prevention in osteoporosis. Previous landmark studies have primarily focused on bone mineral density and fracture outcomes rather than quality of life measures. The finding that resistance training shows the strongest HRQoL benefit aligns with evidence supporting its role in improving physical function and reducing fall risk in older adults.

Key methodological limitations include the heterogeneity of HRQoL measurement instruments across studies, which complicates interpretation of the overall pooled result. The certainty of evidence was rated as moderate for resistance training and short-term interventions, but low for longer-duration and multicomponent programs. The lack of reported safety data represents another significant limitation. The setting of included studies was not reported, limiting generalizability. Additionally, the specific characteristics of the comparator groups were not detailed.

Clinical implications suggest that when considering exercise interventions for adults with osteoporosis, resistance training and shorter-duration programs (<20 weeks) may offer meaningful HRQoL benefits. However, clinicians should interpret the overall null finding cautiously due to measurement heterogeneity. The evidence supports incorporating resistance training into osteoporosis management plans when quality of life is a treatment priority, recognizing that the overall evidence base remains mixed.

Unanswered questions include the optimal duration, frequency, and intensity of exercise programs for maximizing HRQoL benefits. The long-term sustainability of HRQoL improvements beyond 20 weeks requires further investigation. Safety profiles of different exercise modalities in this population need clarification. Additionally, how HRQoL improvements translate to other important outcomes like fracture risk, functional independence, and healthcare utilization remains unknown. Further research should standardize HRQoL measurement and include comprehensive safety reporting.
