Falls Prevention in Older Adults: What STRIDE Changed and What the Evidence Still Supports
A landmark pragmatic trial reset expectations for comprehensive risk-factor programs — here is where the strongest evidence now points.
One-Minute Takeaway
- Falls prevention in older adults rests on high-certainty evidence that structured exercise reduces the rate of falls by about 23% (RaR 0.77, 95% CI 0.71–0.83).
- The STRIDE trial randomised 5,451 adults and found a nurse-led multifactorial primary-care strategy did not significantly lower serious fall injuries (HR 0.92, 95% CI 0.80–1.06).
- Home fall-hazard reduction probably lowers the rate of falls by about 26% (RaR 0.74, 95% CI 0.61–0.91), with larger effects in higher-risk adults.
- Multifactorial risk assessment may reduce the rate of falls (RaR 0.77, 95% CI 0.67–0.87) but shows little effect on fractures or hospital admissions.
- Routine high-dose vitamin D does not reduce falls in generally healthy older adults and is no longer advised for that purpose.
The Clinical Problem in Falls Prevention
Falls are the leading cause of injury-related death and disability among older adults. Roughly one-third of community-dwelling adults aged 65 and older fall each year. Fall-related injuries drive a large share of emergency visits, fractures, and loss of independence.
National figures underline the scale. In 2018, about 27.5% of community-dwelling adults 65 and older reported at least one fall in the prior year, and 10.2% reported a fall-related injury. In 2021, an estimated 38,742 deaths in the United States were attributed to fall-related injuries.
For decades the intuitive clinical response was to assess every modifiable risk factor and address them together. The STRIDE trial tested that comprehensive strategy at scale within ordinary primary care. Its result reshaped how the field weighs integrated risk-factor management against simpler, targeted interventions.
The stat cards below anchor the comparison that follows.
Available Approaches
Four broad strategies dominate the primary-care evidence: structured exercise, multifactorial risk assessment, environmental modification, and supplementation. The table sets out the strongest source for each, drawn from systematic reviews and large trials rather than single studies.

Structured Exercise
Exercise carries the strongest and most consistent evidence. The Sherrington 2019 Cochrane review pooled 81 trials of exercise against control and found a 23% reduction in the rate of falls (RaR 0.77, 95% CI 0.71–0.83), rated high certainty across 12,981 participants in 59 studies. Exercise also reduced the number of people who fell (RR 0.85, 95% CI 0.81–0.89).
Not all exercise is equal. Programs emphasising balance and functional movement produced the clearest benefit (RaR 0.76, 95% CI 0.70–0.81). Tai Chi may also reduce the rate of falls, though with lower certainty (RaR 0.81, 95% CI 0.67–0.99). The US Preventive Services Task Force gives exercise a B recommendation for adults at increased risk.
Multifactorial Risk Assessment
Multifactorial care assesses each patient’s specific risk factors — gait, balance, vision, medications, orthostatic blood pressure, and environment — then tailors interventions. The Hopewell 2018 Cochrane review found this approach may reduce the rate of falls (RaR 0.77, 95% CI 0.67–0.87), though certainty was low and heterogeneity was high.
The harder question is whether it reduces harm. In the same review, multifactorial care showed little or no effect on the number of people who fell (RR 0.96), recurrent falls, fractures, or hospital admission (RR 1.00). STRIDE reinforced this pattern: the multifactorial strategy did not significantly lower adjudicated serious fall injuries, even as self-reported fall injuries fell modestly.
Home and Environmental Modification
Environmental strategies target the setting where most falls occur. The Clemson 2023 Cochrane review found that home fall-hazard reduction probably lowers the rate of falls by 26% (RaR 0.74, 95% CI 0.61–0.91), rated moderate certainty. These programs typically involve an occupational-therapist home visit that identifies and remedies hazards.
The benefit concentrates where risk is highest. For adults with a recent fall, recent hospitalisation, or difficulty with daily activities, home-hazard reduction lowered falls by about 38%. Targeting the intervention to higher-risk patients is therefore central to its value.
Supplements and Vitamin D
Vitamin D was once widely recommended for fall prevention, but the evidence has shifted. The DO-HEALTH trial tested daily 2000 IU vitamin D, omega-3s, and a home exercise program in 2,157 generally healthy, active adults aged 70 and older. Vitamin D did not reduce falls in this population, and the simple home exercise program did not either.
Reflecting this, the USPSTF no longer endorses vitamin D to prevent falls in community-dwelling older adults. Correcting documented deficiency remains appropriate for bone health, but high-dose supplementation is not supported as a fall-prevention strategy in replete adults.
Comparative Analysis of Falls Prevention Approaches
Placed side by side, the strategies separate cleanly. Exercise is the only intervention supported by high-certainty evidence for reducing both the rate of falls and the number of fallers. Home-hazard reduction follows, with moderate-certainty benefit that is strongest in higher-risk patients.
Multifactorial assessment occupies an awkward middle. It appears to lower the count of falls, yet that signal has not translated into fewer fractures, hospitalisations, or serious injuries. STRIDE tested the most rigorous version of this approach and did not move the outcome that matters most.
Supplementation sits at the bottom. In replete, active older adults, vitamin D adds no measurable fall-prevention benefit. The practical hierarchy that emerges places targeted exercise and home-hazard reduction ahead of broad multifactorial programs and routine supplements.
Quality and Consistency of the Evidence
- High certainty. Exercise reduces the rate of falls (RaR 0.77) and the number of people who fall (RR 0.85), with consistent effects across 59 or more randomised trials.
- Moderate certainty. Home fall-hazard reduction lowers the rate of falls (RaR 0.74). The USPSTF judges the net benefit of multifactorial care to be small but real.
- Low certainty. The multifactorial effect on rate of falls (RaR 0.77) is imprecise, with high between-trial heterogeneity. The exercise effect on fractures is also low certainty (RR 0.73).
- No demonstrated benefit. Routine high-dose vitamin D does not reduce falls in generally healthy, replete older adults.
What the Evidence Does Not Show
- Multifactorial programs have not shown a reduction in serious fall injuries (STRIDE) or in fractures and hospital admissions (Cochrane), despite lowering the count of falls.
- Head-to-head comparisons of exercise types are limited; the optimal program, dose, and delivery model are not settled.
- Most trials excluded adults with major neurologic disease, including moderate-to-severe dementia, Parkinson disease, and stroke; effectiveness in those groups is uncertain.
- DO-HEALTH enrolled healthy, active seniors, so whether its null supplement findings extend to frailer or vitamin D–deficient adults is unclear.
- Real-world implementation and long-term adherence remain the central challenge; trial efficacy has not reliably translated into effectiveness across ordinary practice.
Practical Implications
The evidence supports leading with exercise. Recommending a structured program that challenges balance and includes functional training aligns with the highest-certainty data and a USPSTF B recommendation. Where local programs exist, referral is preferable to generic advice to “stay active.”
Environmental risk deserves parallel attention. Assessing and reducing home hazards adds value, particularly for patients with a prior fall or other markers of higher risk, and an occupational-therapy home assessment strengthens that step.
Multifactorial assessment is best treated as an individualised decision rather than a routine program, consistent with the USPSTF C recommendation. Reviewing fall-risk-increasing medications and checking orthostatic blood pressure remain reasonable components of tailored risk reduction. Vitamin D is appropriate to correct documented deficiency, not to prescribe broadly for falls.
Evidence Grade and Bottom Line
Overall grade: high for exercise, moderate for home-hazard reduction, low for multifactorial care on rate of falls with no demonstrated benefit for serious injuries, and no benefit for routine vitamin D.
- Exercise and home-hazard reduction are the interventions with the strongest evidence for reducing falls in older adults.
- STRIDE showed that a comprehensive multifactorial primary-care strategy did not reduce serious fall injuries, tempering enthusiasm for one-size integrated programs.
- The most defensible primary-care approach pairs a balance-focused exercise recommendation with targeted home-hazard reduction, individualising any further assessment.
