OBJECTIVES/HYPOTHESIS: Quantify the relationships between dizziness, falls, and obesity among adults.
Cross-sectional analysis of a national health survey.
Adult respondents in the 2008 National Health Interview Survey balance module were analyzed. With demographic information, data for balance and dizziness problems, reported falls, injuries from falls, and body mass index were extracted. Associations between balance/dizziness problems and falls or injuries from falls were determined. The additional association between obesity and falls or fall-related injuries in the setting of a balance/dizziness problem was determined.
Among 216.8 ± 3.5 million adult Americans, 24.2 ± 0.7 million reported dizziness in the past 12 months (11.1% ± 0.3%; mean age, 45.9 ± 0.2 years; 51.7% ± 0.5% female), 11.5% ± 0.3% had fallen in the prior 12 months, and 26.3% ± 0.4% were obese. Among individuals reporting dizziness, 34.3% ± 1.3% reported falls, whereas only 9.1% ± 0.3% of nondizzy individuals reported a fall (odds ratio [OR]: 5.1; P < .001). Among dizzy individuals who reported a fall, 45.8% ± 2.1% were injured by the fall versus 35.6% ± 1.4% nondizzy individuals who fell (OR: 1.5; P < .001). The addition of obesity to dizziness increased the odds of falling by 1.3 (95% confidence interval: 1.2-1.5; P < .001) but did not significantly increase the odds of fall-related injury (P = .110).
Dizziness/balance problems are strongly associated with both an increased tendency to fall and increased injury rate from falls among adults. The addition of obesity to dizziness was associated with a higher rate of falling but was not associated with a significantly higher rate of fall-related injury. Balance problems in conjunction with obesity need to be targeted in fall-prevention efforts.

目的/假设：量化成年人头晕、跌倒与肥胖之间的关系。
一项全国健康调查的横断面分析。
对2008年全国健康访谈调查平衡模块中的成年受访者进行分析。提取人口统计学信息、平衡和头晕问题、报告的跌倒、跌倒受伤情况以及体重指数的数据。确定平衡/头晕问题与跌倒或跌倒受伤之间的关联。确定在存在平衡/头晕问题的情况下肥胖与跌倒或与跌倒相关的损伤之间的额外关联。
在2.168±0.035亿成年美国人中，有2420±70万在过去12个月内报告有头晕（11.1%±0.3%；平均年龄45.9±0.2岁；51.7%±0.5%为女性），11.5%±0.3%在之前12个月内有跌倒，26.3%±0.4%肥胖。在报告头晕的个体中，34.3%±1.3%报告有跌倒，而在无头晕的个体中只有9.1%±0.3%报告有跌倒（优势比[OR]：5.1；P<0.001）。在报告跌倒的头晕个体中，45.8%±2.1%因跌倒受伤，而在跌倒的无头晕个体中为35.6%±1.4%（OR：1.5；P<0.001）。在头晕的基础上增加肥胖会使跌倒几率增加1.3（95%置信区间：1.2 - 1.5；P<0.001），但并未显著增加与跌倒相关损伤的几率（P = 0.110）。
头晕/平衡问题与成年人跌倒倾向增加和跌倒受伤率增加密切相关。在头晕的基础上增加肥胖与更高的跌倒率相关，但与显著更高的与跌倒相关的损伤率无关。在预防跌倒的努力中，需要针对平衡问题与肥胖问题。
