■嗅觉功能障碍(OD)是一种主要影响老年人的疾病。OD涉及几个因素,比如年龄,社会经济地位,和神经退行性疾病;然而,服兵役的效果仍然需要进一步调查。这里,我们的目标是确定在老年人中以前服兵役和OD之间是否存在关联.
■这项横断面研究包括来自全国社会生活第一轮的2268名成年人,健康,老龄化项目。OD定义为在5项Sniffin\'Sticks测试中正确识别的0-3种气味。进行双变量分析以计算先前服兵役与OD的关联的粗比值比(cOR),并确定用于回归的协变量。使用逻辑回归评估了以前服兵役和OD之间的关联,并根据年龄计算调整后的比值比(AOR),性别,种族/民族,教育,中风史,痴呆症,糖尿病,和心理健康。所有分析均使用调查权重进行加权,以说明抽样设计。
■489名成年人存在OD(21.6%)。在那些有OD的人中,平均年龄为71.0±7.9岁,而无OD者的平均年龄为67.0±7.2岁。在患有OD的成年人中,34.4%报告说以前服过兵役,相比之下,没有OD的成年人为27.7%(cOR=1.37;95%CI:1.05-1.79)。然而,在调整协变量后,以前服兵役与OD无关(aOR:1.09;95%CI:0.79-1.50).年龄较大(aOR:1.07;95%CI:1.05-1.09)和精神健康状况较差(aOR:1.68;95%CI:1.14-2.49)与OD相关。
■在控制协变量后,在老年人中,服兵役与OD无关。需要进行更细致的研究,以检查OD与兵役的特定要素之间的相关性,例如持续时间,毒素暴露,还有头部外伤.证据级别:4级。
UNASSIGNED: Olfactory dysfunction (OD) is a condition primarily affecting older adults. Several factors have been implicated in OD, such as age, socioeconomic status, and neurodegenerative disease; however, the effect of military service still requires additional investigation. Here, we aim to determine if there is an association between prior military service and OD among older adults.
UNASSIGNED: This cross-sectional study included 2268 adults from Round 1 of the National Social Life, Health, and Aging Project. OD was defined as 0-3 odors correctly identified on the 5-item Sniffin\' Sticks test. Bivariate analysis was conducted to calculate crude odds ratios (cOR) for the association of prior military service with OD and identify covariates for regression. Associations between prior military service and OD were assessed using logistic regression, and adjusted odds ratios (aOR) were calculated controlling for age, gender, race/ethnicity, education, stroke history, dementia, diabetes, and mental health. All analyses were weighted using survey weights to account for sampling design.
UNASSIGNED: OD was present in 489 adults (21.6%). Among those with OD, the average age was 71.0 ± 7.9 years, whereas the average age in those without OD was 67.0 ± 7.2 years. Among adults with OD, 34.4% reported prior military service, compared to 27.7% of adults without OD (cOR = 1.37; 95% CI: 1.05-1.79). However, after adjusting for covariates, prior military service was not associated with OD (aOR: 1.09; 95% CI: 0.79-1.50). Older age (aOR: 1.07; 95% CI: 1.05-1.09) and worse mental health (aOR: 1.68; 95% CI: 1.14-2.49) were associated with OD.
UNASSIGNED: Prior military service was not associated with OD among older adults after controlling for covariates. More nuanced research is needed to examine correlations between OD and specific elements of military service such as duration, toxin exposure, and head trauma.Level of Evidence: Level 4.
