■从事适当的体育锻炼可以显着降低中老年人患各种疾病的风险。研究最佳的身体活动水平(PA)对于增强该人群的健康至关重要。本研究旨在探讨中国中老年人群每周PA水平与患感冒频率的量效关系,确定必要的PA水平,以有效降低感冒风险。
■我们进行了一项横断面研究,使用基于网络的调查针对中国40岁及以上的个人(n=1,683)。调查收集了有关PA和感冒频率的信息。使用Kruskal-Wallis检验和χ2检验分析数据。我们通过有序多变量逻辑回归模型和受限三次样条模型探索了过去一年中每周PA与寒冷频率之间的剂量反应关系。
■(1)快走成为40岁以上人群的首选体育锻炼。研究结果表明,每周适度(比值比(OR)=0.64,P<0.001,95%置信区间(CI)[0.50-0.81])和高水平(OR=0.64,P<0.001,95%CI[0.51-0.79])的PA水平显着降低了感冒的风险。患有1种(OR=1.47,P<0.001,95%CI[1.20-1.80])或多种慢性疾病(OR=1.56,P<0.001,95%CI[1.21-2.00])的个体风险增加。与中国东部地区相比,中部地区(OR=1.64,P<0.001,95%CI[1.33-02.01])和西部地区(OR=1.49,P=0.008,95%CI[1.11-02.00])的人群面临更高的风险。(2)根据约束三次样条模型,在过去一年中经历过一次感冒的成年人每周PA水平为537.29代谢当量-每周分钟(MET-min/wk),OR值为1.对于那些报告两个或两个以上感冒的人,PA水平为537.76MET-min/wk,OR为1.
■(1)快走是中国中老年人最喜欢的运动,感冒的患病率受到慢性病数量和地理位置的影响。(2)常规,适度的运动可以降低患感冒的风险。为了有效降低冷频率,建议中国中老年人至少进行538MET-min/wk的运动。
UNASSIGNED: Engaging in appropriate physical activity can significantly lower the risk of various diseases among middle-aged and older adults. Investigating optimal levels of physical activity (PA) is crucial for enhancing the health of this demographic. This study aims to explore the dose-response relationship between weekly PA levels and the frequency of colds among Chinese middle-aged and elderly individuals, identifying the necessary PA level to effectively diminish the risk of colds.
UNASSIGNED: We conducted a cross-sectional study using a web-based survey targeting individuals aged 40 and older (n = 1, 683) in China. The survey collected information on PA and the frequency of colds. Data was analyzed using Kruskal-Wallis test and the χ2 test. We explored the dose-response relationship between weekly PA and cold frequency over the past year through an ordered multivariate logistic regression model and a restricted cubic spline model.
UNASSIGNED: (1) Brisk walking emerged as the preferred physical exercise for those over 40. The findings suggest that engaging in moderate (odds ratio (OR) = 0.64, P < 0.001, 95% confidence interval (CI) [0.50-0.81]) and high (OR = 0.64, P < 0.001, 95% CI [0.51-0.79]) levels of PA weekly significantly reduces the risk of catching a cold. Individuals with one (OR = 1.47, P < 0.001, 95% CI [1.20-1.80]) or multiple chronic diseases (OR = 1.56, P < 0.001, 95% CI [1.21-2.00]) were at increased risk. Those residing in central (OR = 1.64, P < 0.001, 95% CI [1.33-02.01]) and western China (OR = 1.49, P = 0.008, 95% CI [1.11-02.00]) faced a higher risk compared to their counterparts in eastern China. (2) According to the restricted cubic spline model, adults who experienced one cold in the past year had a weekly PA level of 537.29 metabolic equivalent-minutes per week (MET-min/wk) with an OR value of 1. For those reporting two or more colds, the PA level was 537.76 MET-min/wk with an OR of 1.
UNASSIGNED: (1) Brisk walking is the most favored exercise among the Chinese middle-aged and elderly, with the prevalence of colds being affected by the number of chronic diseases and the geographic location. (2) Regular, moderate exercise is linked to a lower risk of colds. To effectively reduce cold frequency, it is recommended that middle-aged and elderly Chinese individuals engage in a minimum of 538 MET-min/wk of exercise.
