Background: The 2008 National Health Interview Survey (NHIS) Balance and Dizziness Supplement is the first household survey of United States civilian, non-institutionalized adults (ages 18+) to include extensive coverage of disturbances in balance and vestibular function.

Objective: To investigate associations between dizziness/imbalance and chronic health conditions with falling risk during the past year.

Methods: Respondents (N=21,781) were asked about dizziness/imbalance (DI) symptoms, use of balance aids, physical and psychological problems, health care utilization and outcomes. Characteristics of frequent fallers (FF) who reported falling at least once a month were compared to those falling less (FL) often and those that did not fall (NF).

Results: Annual DI symptom prevalence was 14.8% (33.4 million adults); higher for women, 18.3%, than men, 11.1%. DI was associated with ages 65+ (OR=2.03, CI=1.80–2.29), females (OR=1.79, CI=1.62–1.96), non-Hispanic whites (OR=1.43, CI=1.28–1.61), and family incomes below $35,000 (OR=1.63, CI=1.43–1.86). FF prevalence was 1.3%, FL 10.1%, and NF 88.6%. Respondents with DI accounted for 64.1% of FF; age/sex did not increase falling risk of these subjects. Unsteadiness (28.0%) was the most common bothersome symptom, followed by lightheadedness (18.4%) and fainting (16.3%). FF with DI had increased multivariately-adjusted risks in association with movement disorders (OR=4.68, CI=1.58–13.90), stroke (OR=3.26, CI=1.90–5.60), depression (OR=2.18, CI=1.38–3.44), vision problems (OR=2.15, CI=1.31–3.52), epilepsy/seizures (OR=2.04, CI=0.99–4.18), diabetes (OR=1.89, CI=1.06–3.39), and head/brain injury (OR=1.87, CI=1.12–13.90). Injuries from falling were reported by 46.9%. Half (51.9%) of FF with DI symptoms reported health conditions as reasons for falling.

Conclusions: DI symptoms in combination with chronic health conditions are strongly associated with frequent, injurious falls.

Learning Objectives:
Demonstrate the high prevalence among U.S. adults of chronic dizziness and balance problems and the impact these disturbances in balance function have on the risk of falls and injuries related to falls.
