Guidelines recommend a healthy lifestyle and regularly physical activity (PA) after kidney transplantation (KTx). The KTx360° program is a multicenter, multisectoral, multimodal, telemedicine-based follow-up care program. Effects of the first COVID-19 wave restrictions on health-related quality of life and PA of supervised KTx360° patients were evaluated using an online questionnaire. Six hundred and fifty-two KTx360° patients were contacted via email and were asked to complete the Freiburg questionnaire of physical activity and the Short form 12 Health Survey (SF-12) online. Pre-pandemic and lockdown data were compared in 248 data sets. While sporting activity decreased during the COVID-19 pandemic, basic and leisure activity increased, resulting in increased overall activity. The physical component scale of the SF-12 was in the low normal range before as well as during the pandemic, with a small but significant increase during the pandemic. The mental component scale showed normal values before and during pandemic with a small but statistically significant decrease. Our study supports the effectiveness of a telemedicine based program for KTx patient care in maintaining PA and quality of life during the first peak of the COVID-19 pandemic. However, further research and observation during the ongoing pandemic are required.
INTRODUCTION: Metabolic syndrome (MetS) is a major health problem worldwide and the main risk factor for metabolic-associated fatty liver disease (MAFLD). Established treatment options are lifestyle interventions facilitating dietary change and increased physical activity. Here, we tested the effect of a telemonitoring-supported intervention on liver parameter of inflammation and fibrosis in individuals with MetS. METHODS: This was a prospective, randomized, parallel-group, and assessor-blind study performed in workers of the main Volkswagen factory (Wolfsburg, Germany). Volunteers with diagnosed MetS were randomly assigned (1:1) to a 6-month lifestyle intervention focusing on supervised, activity-tracker–guided exercise or to a waiting-list control group. This secondary analysis assessed the effect of the intervention on liver enzymes and MAFLD-related parameters. RESULTS: We screened 543 individuals between October 10, 2017, and February 27, 2018, of whom 314 were randomly assigned to the intervention group (n = 160) or control group (n = 154). Liver transaminases, alkaline phosphatase, and gamma-glutamyl transferase significantly decreased after 6 months in the intervention group compared with the CG. Furthermore, an aspartate aminotransferase-to-platelet ratio index score as a marker for liver fibrosis significantly decreased in the intervention group. These improvements were associated with changes in obesity and exercise capacity. DISCUSSION: A 6-month lifestyle intervention based on exercise training with individualized telemonitoring-based supervision led to improvements of liver inflammation and fibrosis in employees with MetS. Therefore, this intervention shows therapeutic potential for individuals at high risk of MAFLD ( ClinicalTrials.gov Identifier: NCT03293264).
BackgroundElectrically assisted bicycles (e-bikes) have become increasingly popular and may facilitate active commuting and recreational cycling.ObjectiveTo evaluate the physical activity levels and usage characteristics of e-bikers and conventional cyclists under real-world conditions.MethodsWe conducted a prospective observational study in Germany to examine the effects of e-biking compared with conventional cycling on reaching the World Health Organization (WHO) target for physical activity—at least 150 min of moderate-to-vigorous physical activity (MVPA) per week. Study participants (1250 e-bikers and 629 conventional bike users) were equipped with activity trackers to assess the time, distance and heart rate during cycling over four consecutive weeks. Questionnaires were used to assess any traffic accidents incurred over 12 months.ResultsThe proportion of participants reaching 150 min of MVPA per week was higher for conventional bike users than for e-bike users (35.0% vs 22.4%, p<0.001). In a multiple regression model, the odds of reaching the physical activity target were lower for e-biking than for conventional biking (OR=0.56; 95% CI 0.43 to 0.72) with age, sex, comorbidities and bike usage patterns as confounding factors. No significant differences were observed between bike groups for traffic accidents, yet when controlled for cycling time and frequency of cycling e-bikers had a higher risk of a traffic accident (OR=1.63; 95% CI 1.02 to 2.58).ConclusionE-bikes are associated with a lower probability of reaching WHO targets for MVPA due to reduced duration and a reduced cardiovascular effort during riding. However, e-bikes might facilitate active transportation, particularly in older individuals or those with pre-existing conditions.
Background Metabolic syndrome (MetS) is associated with an increased risk for cardiovascular events and high socioeconomic costs. Despite lifestyle interventions focusing on exercise are effective strategies to improve parameters of the above aspects, many programs fail to show sustained effects in the long-term. Methods At visit 2 (V2) 129 company employees with diagnosed MetS, who previously participated in a 6-month telemonitoring-supported exercise intervention, were randomized into three subgroups for a 6-month maintenance treatment phase. A wearable activity device was provided to subgroup A and B to assess and to track physical activity. Further subgroup A attended personal consultations with individual instructions for exercise activities. Subgroup C received neither technical nor personal support. 6 months later at visit (V3), changes in exercise capacity, MetS severity, work ability, health-related quality of life and anxiety and depression were compared between the subgroups with an analysis of variance with repeated measurements. Results The total physical activity (in MET*h/week) declined between visit 2 and visit 3 (subgroup A: V2: 48.0 ± 33.6, V3: 37.1 ± 23.0; subgroup B: V2: 52.6 ± 35.7, V3: 43.8 ± 40.7, subgroup C: V2: 51.5 ± 29.7, V3: 36.9 ± 22.8, for all p = 0.00) with no between-subgroup differences over time (p = 0.68). In all three subgroups the initial improvements in relative exercise capacity and MetS severity were maintained. Work ability declined significantly in subgroup C (V2: 40.3 ± 5.0, V3: 39.1 ± 5.7; p < 0.05), but remained stable in the other subgroups with no between-subgroup differences over time (p = 0.38). Health-related quality of life and anxiety and depression severity also showed no significant differences over time. Conclusions Despite the maintenance of physical activity could not be achieved, most of the health related outcomes remained stable and above baseline value, with no difference regarding the support strategy during the maintenance treatment phase. Trial registration The study was completed as a cooperation project between the Volkswagen AG and the Hannover Medical School (ClinicalTrials.gov Identifier: NCT02029131).
BackgroundTo examine the association between COVID-19 vaccination status and physical activity (PA), sporting behavior, as well as barriers to PA in adults in Switzerland, Germany, and Austria.MethodsA total of 1516 adults provided complete responses to our online questionnaire sent out in August 2021. Information about self-reported PA categories, sporting behavior, barriers to PA, and COVID-19 vaccination status were gathered. Main analyses were done using multiple linear regression adjusted for relevant parameters.ResultsWe found a significant association of vaccination status with total PA (p = .011), vigorous PA (p = .015), and moderate PA (p = .001) but not transport-related PA or sedentary time. Unvaccinated adults tended to have more total and vigorous PA than those vaccinated once (ratios of geometric means: 1.34 and 1.60, respectively) or twice (1.22 and 1.09, respectively). Yet, not sufficient evidence was available to confirm this. There was no between-group difference in the contribution of leisure time, work-related, or transport-related PA to total PA. Vaccination status was not associated with sporting behavior except for jogging as the primary intensive type of sports. Finally, there were no significant differences in any of the COVID-19 specific barriers to PA between groups.ConclusionOur data showed that vaccination status is associated with PA even in summer, where the number of COVID-19 cases was low and the severity of safety measures was mild. These findings may enhance future research and improve/extend COVID-19-specific PA guidelines.
Background: Lifestyle changes are a cornerstone in the treatment of metabolic syndrome (MetS). However, evidence as to which components of the MetS and associated aspects of quality of life are driven by weight loss or improvements in exercise capacity are scarce. Methods: Company employees (n = 302, 48.2 ± 8.2 years, BMI 33.2 ± 5.4 kg/m2) with diagnosed MetS were evaluated after a 6-month telemonitoring-supported intervention (counselling in nutrition and physical activity) or wait-list control (delayed start of the same intervention). Results: Exercise capacity, body mass index (BMI), and MetS severity were improved after the intervention. Multivariable regression models revealed that changes in BMI were associated with changes in three components of MetS (waist circumference, triglycerides, blood glucose), whereas changes in exercise capacity only were associated to one MetS component change (systolic blood pressure) but also improvements in anxiety severity, aspects of quality of life, and work ability. Conclusions: Both physical activity promotion and diet should be part of a holistic treatment of patients with MetS. However, our data suggest that dietary-induced weight loss might be more successful when aiming at improving MetS risk factors, whereas focusing more on physical activity promotion might be preferred when targeting aspects in quality of life and mental health.
Anxiety disorders are among the most common distressing diseases worldwide and have been the focus of increasing attention by companies, as they are associated with impaired work performance, higher absenteeism, and greater health-related costs. The risk of disease is particularly pronounced in individuals with metabolic syndrome and unfavorable working conditions. Nevertheless, empirical knowledge on interactions of metabolic syndrome, job characteristics, and psychiatric morbidity is still sparse. This cross-sectional study included survey data from 176 company employees with diagnosed metabolic syndrome to examine associations between anxiety and job-related factors, namely goal uncertainty and job autonomy. Descriptive data analysis along with Spearman's rank correlation analysis were performed. Study hypotheses were tested using moderated hierarchical multiple regression analyses. Results extend worksite health promotion literature by demonstrating a slightly U-shaped relation between goal uncertainty and anxiety (β=.16, p≤.05). While moderate levels of goal uncertainty contributed to well-being in terms of low anxiety severity, low and high goal uncertainty were associated with more severe anxiety. This highlights the need to consider differentiated stressor conceptualizations in research on antecedents of employees' well-being. However, job autonomy showed neither a direct nor a moderating effect on anxiety.
