目的探讨中老年良性位置性眩晕急性发作的危险因素。方法对136例中老年良性位置性眩晕患者进行问卷调查,采用单因素及多因素logistic回归分析良性位置性眩晕急性发作的危险因素。结果136例患者中38例(27.94%)有良性位置性眩晕急性发作,急性发作次数2~12(5.7±1.1)次,每次发作持续时间5~40(15±5)min;有过度疲劳、存在精神和心理因素、脑力劳动、有内耳疾病、有全身疾病者急性发作率(75.76%、72.92%、82.50%、90.91%、80.56%)高于无过度疲劳、无精神和心理因素、体力劳动、无内耳疾病、无全身疾病者(4.40%、3.41%、5.21%、7.77%、9.00%)(P<0.05);多因素logistic回归分析结果显示,过度疲劳(OR=1.234,95%CI:1.352~1.478,P=0.014)、有精神和心理因素(OR=1.357,95%CI:1.451~1.831,P=0.013)、脑力劳动(OR=1.784,95%CI:1.351~1.467,P=0.003)、有内耳疾病(OR=1.243,95%CI:1.367~1.841,P=0.006)、有全身疾病(OR=1.955,95%CI:1.271~1.578,P=0.031)是中老年良性位置性眩晕急性发作的独立危险因素。结论过度疲劳、存在精神及心理因素、脑力劳动、有内耳疾病及全身疾病是中老年良性位置性眩晕急性发作的危险因素。
Objective To explore the risk factors for acute exacerbation of middle-aged and elderly patients with positional vertigo. Methods A total of 136 middle-aged and elderly patients with benign positional vertigo were investigated by questionnaires. Univariate and multivariate logistic regression analysis was used to analyze the risk factors of acute positional vertigo. Results Thirty-eight of the 136 patients (27.94%) had an acute onset of benign positional vertigo. The number of acute attacks ranged from 2 to 12 (5.7 ± 1.1) and the duration of each attack was 5 to 40 (15 ± 5) min. (75.76%, 72.92%, 82.50%, 90.91%, 80.56%) were higher than those without fatigue, without mental and psychological factors, with mental and psychological factors, mental work, inner ear diseases, (OR = 1.234, 95% CI, P <0.05). Multivariate logistic regression analysis showed that over fatigue (OR = 1.234, 95% CI : 1.352-1.478, P = 0.014), mental and psychological factors (OR = 1.357,95% CI: 1.451-1.831, P = 0.013), mental labor (OR = 1.784,95% CI: 1.351-1.467, P = (OR = 1.955, 95% CI: 1.271-1.578, P = 0.031), which were the location of inner ear disease (OR = 1.243,95% CI: 1.367-1.841, P = 0.006) Independent risk factors for acute episodes of dizziness. Conclusion Excessive fatigue, mental and psychological factors, mental labor, inner ear diseases and systemic diseases are risk factors of acute positional vertigo in middle-aged and elderly patients.
