背景:平衡障碍会引起不稳定的感觉,头昏眼花,眩晕,不平衡,或者晕厥,最终导致严重的医疗,物理,情感,和社会后果。这些病症在40岁及以上的个体中非常普遍。屏幕时间包括与电视观看相关的活动,玩电子游戏,和非工作相关的计算机使用。长时间的屏幕暴露可能会导致一系列健康问题,甚至会提高总死亡率。然而,关于过度的屏幕时间和平衡功能障碍之间潜在联系的现有证据仍然有限.
目的:本研究的主要目的是探讨长时间暴露于屏幕与平衡功能受损之间的可能关联。
方法:这项横断面研究利用了1999年至2002年间在NHANES数据库中完成综合问卷的参与者的数据,这些参与者的年龄均在40岁以上,85岁以下。参与者的筛选时间分为两组(<4h/d和≥4h/d)进行后续数据分析。Logistic回归,结合倾向评分匹配(PSM),用于研究屏幕时间与平衡障碍之间的相关性。
结果:本研究共纳入5176名参与者,由2586名男性和2590名女性组成,平衡障碍的患病率为25.7%(1331/5176)。与每天在屏幕上花费4小时或更多时间的个体相比,在屏幕时间较少的个体中,平衡障碍的发生率明显更高(P<0.001)。对不匹配队列进行的多变量逻辑分析显示,屏幕时间与平衡障碍之间存在显着关联。比值比(OR)1.8(95CI1.57~2.05)。即使在调整了混杂因素后,这些发现仍然保持一致,产生OR1.43(95CI1.24~1.66)。此外,当采用各种多变量分析时,如倾向得分匹配调整模型,标准化死亡率加权模型和成对算法模型;所有结果的OR范围为1.38至1.43,p值<0.001。
结论:控制所有协变量后,屏幕时间(看电视,玩电子游戏,并且在工作之外使用计算机)与中年人和老年人的平衡功能障碍有关。这一发现可能为预防头晕和平衡障碍提供可能的想法。然而,更多的研究必须进一步验证这些结果.
BACKGROUND: Balance disorders can give rise to sensations of instability, lightheadedness, vertigo, disequilibrium, or syncope, ultimately leading to grave medical, physical, emotional, and societal ramifications. These conditions are highly prevalent among individuals aged 40 and above. Screen time encompasses activities associated with television viewing, video game playing, and non-work-related computer usage. Prolonged screen exposure may engender a spectrum of health issues and even elevate overall mortality rates. However, the available evidence on the potential link between excessive screen time and balance dysfunction remains limited.
OBJECTIVE: The primary aim of this study was to explore the possible association between prolonged screen exposure and impaired balance function.
METHODS: This cross-sectional study utilized data from participants who completed a comprehensive questionnaire in the NHANES database between 1999 and 2002, all of whom were aged over 40 and under 85 years. Participants\' screen time was categorized into two groups (< 4 h/d and ≥4 h/d) for subsequent data analysis. Logistic regression, combined with propensity score matching (PSM), was employed to investigate the correlation between screen time and balance disorders.
RESULTS: A total of 5176 participants were enrolled in this study, comprising 2,586 men and 2,590 women, with a prevalence rate of balance disorders at 25.7% (1331/5176). The incidence of balance disorders was found to be significantly higher among individuals who spent 4 hours or more per day on screen time compared to those with less screen time (P<0.001). Multivariate logistic analysis conducted on the unmatched cohort revealed a significant association between screen time and balance disorders, with an odds ratio (OR) 1.8 (95%CI 1.57 ∼ 2.05). These findings remained consistent even after adjusting for confounding factors, yielding an OR 1.43 (95%CI 1.24 ∼ 1.66). Moreover, the association persisted when employing various multivariate analyses such as propensity score matching adjusted model, standardized mortality ratio weighting model and pairwise algorithmic model; all resulting in ORs ranging from 1.38 to 1.43 and p-values < 0.001.
CONCLUSIONS: After controlling for all covariates, screen time (watching TV, playing video games, and using computers outside of work) was associated with balance dysfunction among middle-aged and older adults. This finding may offer a possible idea for the prevention of dizziness and balance disorders. Nevertheless, additional research is imperative to further validate these results.
