As people get older, they may fall more often for a variety of reasons including problems with balance, poor vision, and dementia. Up to 30% may fall in a year. Although one in five falls may require medical attention, less than one in 10 results in a fracture.
This review looked at the healthcare literature to establish which fall prevention interventions are effective for older people living in the community, and included 159 randomised controlled trials with 79,193 participants.  
Group and home-based exercise programmes, usually containing some balance and strength training exercises, effectively reduced falls, as did Tai Chi. Overall, exercise programmes aimed at reducing falls appear to reduce fractures.
Multifactorial interventions assess an individual's risk of falling, and then carry out treatment or arrange referrals to reduce the identified risks. Overall, current evidence shows that this type of intervention reduces the number of falls in older people living in the community but not the number of people falling during follow-up. These are complex interventions, and their effectiveness may be dependent on factors yet to be determined.  
Interventions to improve home safety appear to be effective, especially in people at higher risk of falling and when carried out by occupational therapists. An anti-slip shoe device worn in icy conditions can also reduce falls.
Taking vitamin D supplements does not appear to reduce falls in most community-dwelling older people, but may do so in those who have lower vitamin D levels in the blood before treatment.  
Some medications increase the risk of falling. Three trials in this review failed to reduce the number of falls by reviewing and adjusting medications. A fourth trial involving family physicians and their patients in medication review was effective in reducing falls. Gradual withdrawal of a particular type of drug for improving sleep, reducing anxiety, and treating depression (psychotropic medication) has been shown to reduce falls.
Cataract surgery reduces falls in women having the operation on the first affected eye. Insertion of a pacemaker can reduce falls in people with frequent falls associated with carotid sinus hypersensitivity, a condition which causes sudden changes in heart rate and blood pressure.
In people with disabling foot pain, the addition of footwear assessment, customised insoles, and foot and ankle exercises to regular podiatry reduced the number of falls but not the number of people falling.
The evidence relating to the provision of educational materials alone for preventing falls is inconclusive.

Interventions for preventing falls in older people living in the community

An overview of mortality and sequelae of preterm birth from infancy to adulthood.

Background 
Approximately 30% of people over 65 years of age living in the community fall each year.
Objectives
To assess the effects of interventions to reduce the incidence of falls in older people living in the community.
Search strategy
We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL (The Cochrane Library 2008, Issue 2), MEDLINE, EMBASE, CINAHL, and Current Controlled Trials ( all to May 2008).
Selection criteria
Randomised trials of interventions to reduce falls in community-dwelling older people. Primary outcomes were rate of falls and risk of falling.
Data collection analysis
Two review authors independently assessed trial quality and extracted data. Data were pooled where appropriate.
Main results
We included 111 trials ( 55,303 participants). Multiple-component group exercise reduced rate of falls and risk of falling (rate ratio (RaR) 0.78, 95% CI 0.71 to 0.86; risk ratio (RR) 0.83, 95% CI 0.72 to 0.97), as did Tai Chi ( RaR 0.63, 95% CI 0.52 to 0.78; RR 0.65, 95% CI 0.51 to 0.82), and individually prescribed multiple-component home-based exercise ( RaR 0.66, 95% CI 0.53 to 0.82; RR 0.77, 95% CI 0.61 to 0.97).
Assessment and multifactorial intervention reduced rate of falls (RaR 0.75, 95% CI 0.65 to 0.86), but not risk of falling.
Overall, vitamin D did not reduce falls ( RaR 0.95, 95% CI 0.80 to 1.14; RR 0.96, 95% CI 0.92 to 1.01), but may do so in people with lower vitamin D levels.
Overall, home safety interventions did not reduce falls ( RaR 0.90, 95% CI 0.79 to 1.03); RR 0.89, 95% CI 0.80 to 1.00), but were effective in people with severe visual impairment, and in others at higher risk of falling. An anti- slip shoe device reduced rate of falls in icy conditions ( RaR 0.42, 95% CI 0.22 to 0.78).
Gradual withdrawal of psychotropic medication reduced rate of falls ( RaR 0.34, 95% CI 0.16 to 0.73), but not risk of falling. A prescribing modification programme for primary care physicians significantly reduced risk of falling ( RR 0.61, 95% CI 0.41 to 0.91).
Pacemakers reduced rate of falls in people with carotid sinus hypersensitivity ( RaR 0.42, 95% CI 0.23 to 0.75). First eye cataract surgery reduced rate of falls ( RaR 0.66, 95% CI 0.45 to 0.95).
There is some evidence that falls prevention strategies can be cost saving.
Authors' conclusions
Exercise interventions reduce risk and rate of falls. Research is needed to confirm the contexts in which multifactorial assessment and intervention, home safety interventions, vitamin D supplementation, and other interventions are effective.

Objective. A prospective study of retinopathy of prematurity (ROP) of 505 infants who weighed <1701 g at birth was undertaken in the mid-1980s. This cohort was traced at 10 to 12 years of age to determine how low birth weight alone and ROP might influence their ophthalmic outcome. Methods. Outcome measures were 1) visual functions (visual acuity, contrast sensitivity, stereoacuity, perimetry, and color vision), 2) presence of strabismus, and 3), measurements of eye size and the dimensions of its components including refractive state. A total of 169 11-year-olds who were born at term were recruited as control subjects and examined under the same conditions. Results. A total of 448 of the original cohort were traced, and 254 consented to a further examination. Compared with the control group, the follow-up cohort differed significantly with reduced visual functions and increased incidence of both myopia and strabismus. Compared with published data, eye size was smaller in the low birth weight cohort. To summarize the ophthalmic data, we defined ophthalmic morbidity as visual acuity below 0.0 log units or the presence of strabismus, myopia, color vision defect, or visual field defect. The rate of ophthalmic morbidity was 50.8% (n = 129/254) in the study cohort compared with 19.5% (n = 33/169) in the control group. The highest rate of ophthalmic morbidity was associated with severe ROP (stages 3/4), although those with no ROP had a less favorable outcome than the control group. Conclusion. This study shows that low birth weight children are at increased risk of visual impairments compared with children who are born at full term. Visual impairments are associated with low birth weight per se and severe ROP. Regressed mild ROP is only a risk factor for strabismus. The functional significance of these deficits is largely unknown.

Long-term ophthalmic outcome of low birth weight children with and without retinopathy of prematurity.

OBJECTIVE: We tested the specific hypothesis that the presentation of auditory processing disorder (APD) is related to a sensory processing deficit. METHODS: Randomly chosen, 6- to 11-year-old children with normal hearing (N = 1469) were tested in schools in 4 regional centers across the United Kingdom. Caregivers completed questionnaires regarding their participating children9s listening and communication skills. Children completed a battery of audiometric, auditory processing (AP), speech-in-noise, cognitive (IQ, memory, language, and literacy), and attention (auditory and visual) tests. AP measures separated the sensory and nonsensory contributions to spectral and temporal perception. RESULTS: AP improved with age. Poor-for-age AP was significantly related to poor cognitive, communication, and speech-in-noise performance (P CONCLUSIONS: Presenting symptoms of APD were largely unrelated to auditory sensory processing. Response variability and cognitive performance were the best predictors of poor communication and listening. We suggest that APD is primarily an attention problem and that clinical diagnosis and management, as well as further research, should be based on that premise.

Nature of Auditory Processing Disorder in Children

Objective: To prospectively study infants of birth weight less than 1701 g in the East Midlands of England in the mid 1980s at 10 to 12 years of age to determine the incidence and risk factors for strabismus in children born preterm. Methods: Low-birth-weight children (n=572) who had been examined during the neonatal period were invited for a follow-up visit at age 10 to 12 years; 169 elevenyear-old schoolchildren born at full term were also recruited (the school cohort). Results: Of the original 572 children, 293 consented to further examination. There was no significant difference between children who were examined and those who were not in terms of birth weight, gestational age, retinopathy of prematurity, and cranial ultrasound abnormalities. Compared with the school cohort (n=5 [3.0%]; 95% confidence interval, 1.0%-9.1%), the low-birthweight cohort had a significant increase in the prevalence of strabismus (n=59 [20.1%]; 95% confidence interval, 15.9%-25.0%; P.001). Compared with published data, there was a relative increase in the occurrence of exotropia in the low-birth-weight study cohort. Multivariate analysis, by backward logistic regression, indicated that retinopathy of prematurity, birth weight, cerebral palsy, anisometropia, and refractive error were all independently associated with strabismus (P.05). Conclusions: The results of this study confirm the increased prevalence of strabismus in a low-birth-weight population. This study also provides more detailed information on risk factors and strabismus types.

Strabismus in children of birth weight less than 1701 g.

Aims: To determine the refractive status and ocular dimensions of a cohort of children at age 10–12 years with birth weight below 1701 g, and also the relation between the neonatal ophthalmic findings and subsequent refractive state. Methods: 293 low birthweight children who had been examined in the neonatal period were assessed at 10–12 years of age. The examination consisted of autorefraction, keratometry, and A-scan. Results of right eyes were compared with published normative data. Results: 293 of the birth cohort of 572 children consented to participate. The average mean spherical equivalent (MSE) in the low birthweight cohort was +0.691 dioptre, significantly higher than the control data (+0.30D, p = 0.02). The average change in MSE over the 10–12 year period was −1.00 dioptre (n = 256), but only 62.1% of cases showed a shift in refractive error of the appropriate magnitude and direction. The presence of any retinopathy of prematurity (ROP) increases the risk of developing anisometropia sixfold. Conclusions: Low birth weight and ROP both significantly impact the refractive state in the long term. At age 10–12 years children born preterm have an increased prevalence of all refractive errors. In low birthweight children refractive state is relatively stable over the first decade of life with a shift towards myopia of 1 dioptre.
