Fall Prevention Interventions and Fracture Risk in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

TL;DR

This study reviews whether fall prevention programs can reduce fractures in older adults, finding mixed results for hip fractures but no overall fracture reduction.

Contribution

The study provides a systematic review and meta-analysis of fall prevention interventions' effects on fracture outcomes in older adults.

Findings

Fall prevention interventions significantly reduced falls but did not significantly prevent fractures overall.

Hip fracture risk showed non-significant reductions in two trials, with very low certainty in evidence.

There was significant heterogeneity in fracture outcomes across studies.

Abstract

Introduction: Falls and subsequent fractures represent a major public health concern among older adults. While fall prevention interventions have demonstrated efficacy in reducing falls, their impact on fracture outcomes remains unclear. Methods: We conducted a systematic review and meta-analysis following PRISMA 2020 guidelines. We searched multiple databases up to 7 June 2025 for studies investigating fall prevention interventions and fracture outcomes in community-dwelling older adults. A primary outcome was hip fractures; secondary outcomes included any fractures, falls, and serious fall injuries. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated, using random-effects meta-analysis where appropriate. Results: Seventeen studies were included, spanning over 25,000 participants. Interventions included exercise programs, multifactorial approaches, medication optimization, and vitamin D supplementation. For hip fractures, only two randomized controlled trials (RCTs) reported extractable outcome data (12,489 participants; 132 events); both showed non-significant reductions favoring intervention (RR 0.80–0.87), precluding pooled meta-analysis. For any fractures, five studies (18,519 participants; 1343 events) demonstrated no significant effect (RR 0.91, 95% CI 0.72–1.14; p-value = 0.40) with significant heterogeneity (I2 = 65%). Fall prevention interventions significantly reduced falls across 14 studies. GRADE assessment indicated very low certainty for both hip fractures and any fractures due to limited studies, inconsistency, and imprecision. Conclusions: Current evidence suggests fall prevention interventions may reduce hip fractures but do not significantly prevent fractures overall. Despite consistent fall reduction, the translation to fracture prevention remains uncertain, highlighting the need for integrated interventions targeting both fall risk and bone health.
