Infections with the coronavirus disease 2019 (COVID-19) and disorders of the heart and blood vessels are causally related. To ascertain the causal relationship between COVID-19 and cardiovascular disease (CVD), we carried out a Mendelian randomization (MR) study through a method known as inverse variance weighting (IVW). When analyzing multiple SNPs, MR can meta-aggregate the effects of multiple loci by using IVW meta-pooling method. The weighted median (WM) is the median of the distribution function obtained by ranking all individual SNP effect values according to their weights. WM yields robust estimates when at least 50% of the information originates from valid instrumental variables (IVs). Directed gene pleiotropy in the included IVs is permitted because MR–Egger does not require a regression straight line through the origin. For MR estimation, IVW, WM and MR-Egger were employed. Sensitivity analysis was conducted using funnel plots, Cochran's Q test, MR–Egger intercept test, MR–PRESSO, and leave-one-out analysis. SNPs related to exposure to COVID-19 and CVD were compiled. CVD for COVID-19 infection, COVID-19 laboratory/self-reported negative, and other very severe respiratory diagnosis and population were randomly assigned using MR. The COVID-19 laboratory/self-reported negative results and other very severe respiratory confirmed cases versus MR analysis of CVD in the population (p > 0.05); COVID-19 infection to CVD (p = 0.033, OR = 1.001, 95%CI: 1.000–1.001); and the MR–Egger results indicated that COVID-19 infection was associated with CVD risk. This MR study provides preliminary evidence for the validity of the causal link between COVID-19 infection and CVD.

Functional near-infrared spectroscopy (fNIRS) was used to explore the effects of sedentary behavior on the brain functional connectivity characteristics of college students in the resting state after recovering from Corona Virus Disease 2019 (COVID-19). Twenty-two college students with sedentary behavior and 22 college students with sedentary behavior and maintenance of exercise habits were included in the analysis; moreover, 8 min fNIRS resting-state data were collected. Based on the concentrations of oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) in the time series, the resting-state functional connection strength of the two groups of subjects, including the prefrontal cortex (PFC) and the lower limb supplementary motor area (LS), as well as the functional activity and functional connections of the primary motor cortex (M1) were calculated. The following findings were demonstrated. (1) Functional connection analysis based on HbO2 demonstrated that in the comparison of the mean functional connection strength of homologous regions of interest (ROIs) between the sedentary group and the exercise group, there was no significant difference in the mean functional strength of the ROIs between the two groups (). In the comparison of the mean functional connection strengths of the two groups of heterologous ROIs, the functional connection strengths of the right PFC and the right LS (), the left LS (), and the right M1 () in the sedentary group were significantly greater. The functional connection strength between the left PFC and the right LS () and the left LS () was significantly greater. Additionally, the functional connection strength between the right LS and the right M1 () and the left LS () was significantly greater. (2) Functional connection analysis based on HbR demonstrated that there was no significant difference in functional connection strength between the sedentary group and the exercise group () or between the sedentary group and the exercise group (
研究人员利用功能近红外光谱（fNIRS）探讨了久坐行为对大学生从2019年科罗纳病毒病（COVID-19）康复后静息状态下大脑功能连接特性的影响。22名有久坐行为的大学生和22名有久坐行为并保持运动习惯的大学生被纳入分析；此外，还收集了8分钟的fNIRS静息态数据。根据时间序列中氧合血红蛋白（HbO2）和脱氧血红蛋白（HbR）的浓度，计算两组受试者的静息状态功能连接强度，包括前额叶皮层（PFC）和下肢辅助运动区（LS），以及初级运动皮层（M1）的功能活动和功能连接。研究结果如下(1）基于 HbO2 的功能连接分析表明，在比较久坐组和运动组同源感兴趣区（ROIs）的平均功能连接强度时，两组 ROIs 的平均功能强度无显著差异（p>0.05）。在两组异源ROI平均功能连接强度的比较中，久坐组的右侧PFC与右侧LS（p=0.0097）、左侧LS（p=0.0127）和右侧M1（p=0.0305）的功能连接强度明显更大。左侧 PFC 与右侧 LS（p=0.0312）和左侧 LS（p=0.0370）之间的功能连接强度明显更大。此外，右侧 LS 与右侧 M1（p=0.0370）和左侧 LS（p=0.0438）之间的功能连接强度也明显更大。(2) 基于 HbR 的功能连接分析表明，久坐组与运动组之间（p>0.05）或久坐组与运动组之间（p>0.05）的功能连接强度无明显差异。同样，两组同源和异源 ROI 的平均功能连接强度也无明显差异。此外，两组 ROI 的平均功能强度也无明显差异（p>0.05）。实验结果和基于功能连接的图表分析表明，在本实验中，表现出久坐行为的大学生参与者的 fNIRS 信号有所增加。表现出久坐行为的大学生的 fNIRS 信号增加可能与他们感染 SARS-CoV-2 后的状态和久坐的环境有关，这可能是静息态大脑皮层网络功能连接加强的原因。相反，有运动行为的参与者的 fNIRS 信号则有所下降，他们在与久坐者相同的条件下保持了合理的运动习惯。这些结果可能表明，运动行为有可能减轻和减少久坐行为对静息状态大脑皮层网络的影响。

This study aimed to determine the infection status, exercise habits, anxiety levels, and sleep quality in Chinese residents who recovered from infection during the period of coronavirus disease 2019 (COVID-19) period. It also aimed to investigate the influencing factors of recovery status and aid in improving intervention measures for COVID-19 recovery. This study is a sub-study nested within a cross-sectional investigation of infection and physical and mental health among partially recovered residents in all 34 provincial areas of China during the COVID-19 pandemic. A total of 1 013 participants (374 males and 639 females) completed the study. Cardiopulmonary endurance was significantly lower after infection than before infection (p < 0.001). Women (3.92 ± 4.97) exhibited higher levels of anxiety than men (3.33 ± 4.54, p = 0.015). The sleep score was significantly higher after infection (8.27 ± 7.05) than before infection (4.17 ± 4.97, p < 0.001). The active and regular exercise groups exhibited significantly shorter durations of fever than the sedentary and irregular groups (p = 0.033; p = 0.021). Additionally, the active group demonstrated significantly fewer recovery days ([7.32 ± 3.24] days) than the sedentary group ([7.66 ± 3.06] days, p = 0.035). We found a correlation between age and the recovery time of symptoms after COVID-19. We noted that a greater number of symptoms corresponded to poorer cardiopulmonary fitness and sleep quality. Individuals who engage in sedentary lifestyles and irregular exercise regimens generally require prolonged recovery periods. Therefore, incorporating moderate exercise, psychological support, sleep hygiene and other health interventions into post-COVID-19 recovery measures is imperative.

It has been hypothesized that key lifestyle behaviors of physical activity and sleep worsened in response to the Coronavirus disease (COVID-19) pandemic. However, there have been inconsistencies in findings of changes in these key lifestyle behaviors across populations likely due to the wide variety of assessment methods. The purpose of the study was to compare physical activity and sleep before and after the COVID-19 pandemic using accelerometers and self-reported behaviors. A longitudinal follow-up was conducted on students, faculty, and staff at a university campus in the United States. In the periods before March 2020 (covering the academic years of 2018–2019 or 2019–2020) and again in April–June 2021, participants completed surveys to evaluate their physical activity and sleep behaviors and wore an accelerometer. A total of 44 participants completed the survey at both timepoints and 32 completed accelerometer assessment at both timepoints. Fifty-seven percent of participants reported a perceived decline in physical activity, while 30% reported a worsening in sleep. From self-reported data, overall physical activity did not change, but there was a decrease in active transport (p < 0.001) and increase in domestic physical activity (p = 0.012). Sleep quality decreased as evidenced by an increase in Pittsburgh Sleep Quality Index scores (p = 0.045). There were no changes in accelerometer measured physical activity or sleep. There were no changes in physical or mental health. While perceptions of physical activity declined from prior to the COVID-19 pandemic, there were no changes in device-measured physical activity, and changes in self-reported physical activity differed by domain.
