Effects of the COVID-19 pandemic on the global health of women aged 50 to 70 years

A live online exercise program for older adults improves depression and life-space mobility: A mixed-methods pilot randomized controlled trial

BACKGROUND

Aging is the primary risk factor for sarcopenia and mobility limitations. Exercise reduces these risks, but older adults have low levels of participation in physical activity and exercise. We investigated the preliminary effectiveness of a live, online exercise program on community-dwelling older adults' physical activity levels.

METHODS

A mixed-method pilot randomized controlled trial was conducted according to CONSORT 2010 statement: extension for pilot and feasibility trials. Sedentary older adults (65-80 years) were randomly assigned to the online exercise intervention (ACTIVE) or a waitlist control (CON) group. Outcomes were measured pre-randomization and following the 8-week intervention for ACTIVE and CON and two months following the end of the intervention for the ACTIVE group. Outcomes included habitual physical activity levels, depression, anxiety, loneliness, life-space mobility, nutrition risk, and feasibility. All participants were invited to participate post-intervention in individual semi-structured qualitative interviews. Reporting of the qualitative research followed the checklist for the Consolidated Criteria for Reporting research.

RESULTS

Seventeen older adults (71% women) were allocated to ACTIVE group, while 15 were allocated to CON group (87% women). Following the intervention, participants in the ACTIVE group reported reduced symptoms of depression (ACTIVE: pre = 4.2 ± 2.5; post = 2.2 ± 1.9; CON: pre = 3.5 ± 2.1, post = 3.5 ± 2.1; p <0.001) and improved life-space mobility (ACTIVE: pre = 62.4 ± 14.7; post = 71.8 ± 16.0; CON: pre = 65.1 ± 19.0, post = 63.6 ± 22.0; p = 0.003) compared to waitlist control participants. The ACTIVE group had good adherence (97%) and acceptability (98%). Twenty-two participants participated in qualitative interviews. Five themes were identified, including (1) Feasibility of the online exercise program; (2) Perceived health benefits and improvements; (3) Registered Kinesiologists and Physiotherapists contributed to perceived safety; (4) Social connectivity associated with synchronous/live delivery; and (5) Growing old gracefully and preventing disability.

CONCLUSIONS

Our online exercise program was acceptable to older adults, had good adherence, reduced depression, and increased life space. Participants reported improved functional and mental health benefits. Further research is warranted to expand on these findings.

Unveiling the detrimental vicious cycle linking skeletal muscle and COVID-19: A systematic review and meta-analysis

OBJECTIVE

Skeletal muscle catabolism supports multiple organs and systems during severe trauma and infection, but its role in COVID-19 remains unclear. This study investigates the interactions between skeletal muscle and COVID-19.

METHODS

The PubMed, EMbase, and The Cochrane Library databases were systematically searched from January 2020 to August 2023 for cohort studies focusing on the impact of skeletal muscle on COVID-19 prevalence and outcomes, and longitudinal studies examining skeletal muscle changes caused by COVID-19. Skeletal muscle quantity (SMQN) and quality (SMQL) were assessed separately. The random-effect model was predominantly utilized for statistical analysis.

RESULTS

Seventy studies with moderate to high quality were included. Low SMQN/SMQL was associated with an increased risk of COVID-19 infection (OR = 1.62, p < 0.001). Both the low SMQN and SMQL predicted COVID-19-related mortality (OR = 1.53, p = 0.016; OR = 2.18, p = 0.001, respectively). Mortality risk decreased with increasing SMQN (OR = 0.979, p = 0.009) and SMQL (OR = 0.972, p = 0.034). Low SMQN and SMQL were also linked to the need for intensive care unit/mechanical ventilation, increased COVID-19 severity, and longer hospital stays. Significant skeletal muscle wasting, characterized by reduced volume and strength, was observed during COVID-19 infection and the pandemic.

CONCLUSIONS

This study reveals a detrimental vicious circle between skeletal muscle and COVID-19. Effective management of skeletal muscle could be beneficial for treating COVID-19 infections and addressing the broader pandemic. These findings have important implications for the management of future virus pandemics.

Changes in eating habits and lifestyle during the first year of the COVID-19 pandemic across metropolitan regions in Brazil and Germany: A survey-based cross-sectional study

COVID-19 caused profound societal changes to cope rapidly with the new circumstances. The food market changed its quantity, quality, form, and frequency dynamics. Consequently, food-eating habits and lifestyles like physical exercise likely experienced changes. An online-based survey was conducted between June 2020 and January 2021 in the metropolitan regions of Rhine Ruhr Metropolis (RRM), Greater São Paulo (GSP), other metropolitan regions in São Paulo state (oMRSP), other Brazilian metropolitan regions (oBRMR), and the remaining urban areas in both countries (oUA), representing different contexts of Brazil and Germany. We assessed self-reported changes in physical activity level, diet quality, self-reported eating habits, and buying groceries during the first year of the pandemic. In Germany, indoor and outdoor activities increased for 34% of the respondents, while in Brazil, there was a decrease in physical activity for 50% of the participants. The Healthy Eating Index (HEI) scored higher among Brazilians (16.8) than Germans (15.2) on a 0-29 HEI scale. Increased awareness of healthy and sustainable eating habits was observed in GSP (0.7), oMRSP (0.63), oBRMR (0.7), and oUA (0.68) on a scale from no change (0) to change (1). In RRM, an increase in convenience foods was noticed (0.86). Participants reported discomfort with food purchasing due to hygiene measures and avoided going to the supermarket (0.7 on average in Brazil and 0.58 for females using the same 0-1 scale). Also, food supply at the grocery shops was reported to be often unavailable and in lower quantities. A real-time assessment of self-reported changes in eating habits and lifestyle during the lockdown in 2020 in different contexts is insightful for rethinking strategies to improve conditions in the post-COVID-19 era and prepare for future pandemics.

COVID-19 and postural sway: a comparison of individuals with a SARS-CoV-2 history and healthy sedentary women

PURPOSE

The aim of the study was to evaluate the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postural sway in subjects who have recently recovered from infection.

MATERIALS AND METHODS

Fifty-six female individuals with a mild to moderate history of SARS-CoV-2 (n = 25, mean age; 21.13 ± 0.64 years) and healthy sedentary controls (n = 31, mean age; 20.09 ± 1.05 years) were included in the study. Postural sway tests were performed in double and single-leg stance on a force plate with eyes open before and after the neuromuscular fatigue test. The Wingate test was used to induce neuromuscular fatigue. To evaluate the change of the variables determined by the measurements of the groups over time and the group-time interactions, a two-way analysis of variance in repeated measures (mixed design repeated measures ANOVA) was used.

RESULTS

It was found that the SARS-CoV-2 group showed increased total sway path, velocity, and area than those in the healthy group on double and single-leg (right-left) stance (p < 0.05).

CONCLUSIONS

Even if SARS-CoV-2 group individuals have been reported in a mild to moderate outpatient COVID-19 process, they showed deterioration in postural control compared to healthy individuals. In addition, it was found that SARS-CoV-2 accelerated neuromuscular fatigue effects. This can cause more fatigue during activities than individuals who have not had SARS-CoV-2.

Eighteen-Month Changes in Physical Activity, Body Weight, Quadriceps Strength, and Gait Biomechanics during the COVID-19 Pandemic

PURPOSE

This study assessed the effects of the COVID-19 pandemic restrictions/lockdowns on physical activity levels, body mass, quadriceps strength, and gait biomechanics over 18 months.

METHODS

Ten healthy men were assessed at baseline (~14 wk before first lockdown) and 17.9 ± 0.3 months later (<1 wk after second lockdown). At both times, physical activity levels, body mass, and quadriceps strength were acquired using the International Physical Activity Questionnaire, a force plate, and a dynamometer, respectively. Gait data were also acquired using a motion capture system and force plates during self-paced walking, from which spatiotemporal parameters, knee angles, and external moments were computed. Baseline and follow-up measurements were compared using two-tailed paired t -tests ( α = 0.05).

RESULTS

At follow-up, participants spent less time doing vigorous physical activity (∆ = -76 ± 157 min·wk -1 , P = 0.048), exhibited a tendency toward increased sedentary time (∆ = +120 ± 162 min·d -1 , P = 0.056), weighed more (∆ = +2.5 ± 2.8 kg, P = 0.021), and showed a trend toward reduced quadriceps strength (∆ = -0.29 ± 0.45 (N·m)·kg -1 , P = 0.071) compared with baseline. At follow-up, participants walked slower (∆ = -0.09 ± 0.07 m·s -1 , P = 0.005), had greater knee flexion angles at heel strike (∆ = +2.2° ± 1.8°, P = 0.004) and during late stance (∆ = +2.2° ± 1.8°, P = 0.004), had reduced knee extension moments (∆ = -0.09 ± 0.09 (N·m)·kg -1 , P = 0.012) and knee internal rotation moments (∆ = -0.02 ± 0.02 (N·m)·kg -1 , P = 0.012) during late stance.

CONCLUSIONS

Healthy men exhibited reduced physical activity levels, increased body weight, a tendency toward reduced quadriceps strength, and altered gait biomechanics over the initial 18 months of the COVID-19 pandemic-alterations that could have far-reaching health consequences.

High Levels of Glycated Hemoglobin (HbA1c) Are Associated with Physical Inactivity, and Part of This Association Is Mediated by Being Overweight

The COVID-19 pandemic has generated substantial changes in the lives of the population, such as increased physical inactivity, which can lead to being overweight and, consequently, repercussions on glucose homeostasis. A cross-sectional study based on the adult population of Brazil was conducted by stratified, multistage probability cluster sampling (October and December 2020). Participants were classified as physically active or inactive during leisure time according to the recommendations of the World Health Organization. HbA1c levels were categorized as normal (≤6.4%) or with glycemic changes (≥6.5%). The mediating variable was being overweight (overweight and obese). Descriptive, univariate, and multivariate logistic regression analyses examined the association between physical inactivity and glycemic changes. Mediation was analyzed using the Karlson-Holm-Breen method to verify the influence of being overweight on the association. We interviewed 1685 individuals, mostly women (52.4%), 35-59 years old (45.8%), race/ethnicity brown (48.1%), and overweight (56.5%). The mean HbA1c was 5.68% (95% CI: 5.58-5.77). Mediation analysis verified that physically inactive participants during leisure time were 2.62 times more likely to have high levels of HbA1c (OR: 2.62, 95% CI: 1.29-5.33), and 26.87% of this effect was mediated by over-weight (OR: 1.30: 95% CI: 1.06-1.57). Physical inactivity at leisure increases the chances of high levels of HbA1c, and part of this association can be explained by being overweight.

Changes in Behavior After Vaccination and Opinions Toward Mask Wearing: Thoracic Oncology Patient-Reported Experiences During the COVID-19 Pandemic

Background

The COVID-19 vaccines, face masks, and social distancing are effective interventions to prevent SARS-CoV-2 infections. In this study, we aimed to determine lung cancer patients' attitudes toward vaccination, changes in behavior after vaccination, and willingness to continue mask wearing after the pandemic.

Methods

We sent out questionnaires to 220 thoracic oncology patients treated at our lung cancer center in May 2021. The questionnaire focused on patients' vaccination status, self-reported experiences surrounding vaccination, and assessed changes in behaviors before and after vaccination as well as opinions toward mask wearing after the pandemic. Results are presented as absolute and relative frequencies and means with standard deviation and compared using t test, paired t test, and analysis of variance test as well as chi2 test, and Fisher exact text.

Results

About 91.0% of patients reported having received at least 1 vaccination. About 73.3% of patients reported having at least 1 reaction to the vaccination. The most common reactions were pain at the injection site, fatigue, and headache. After vaccination, patients increased contact with family and friends, use of public transport, and grocery shopping. Overall, the level of willingness to wear masks beyond the end of the pandemic differed according to vaccination status.

Conclusions

Acceptance of the COVID-19 vaccination among thoracic oncology patients in Germany was high. Overall, patients with thoracic malignancies tolerated the COVID-19 vaccination well. Rate of adverse reaction was not higher compared with the general population. After the vaccination, patients increased social contacts and usage of public transport. These changes suggest positive psychological effects on quality of life. While reducing social distancing can increase the risk of infection, our results indicate that an extension of mask mandates after the pandemic would likely be accepted by a majority of thoracic oncology patients, suggesting that our cohort was still aware and in support of other measure of protection.

Impact of COVID-19 lockdown on health parameters and muscle strength of older women: A longitudinal study

OBJETIVES

The present study aimed to evaluate the effect of a 13-week COVID-19 lockdown on health-related parameters in women aged 60-70 years.

STUDY DESIGN

Thirty women participated in this longitudinal study. All the assessments were performed before and 13 weeks after the initial phase of the COVID-19 pandemic in Spain (March to June 2020).

MAIN OUTCOME MEASURES

A sociodemographic questionnaire was provided, and tests were performed to assess muscle strength, anthropometric measurements, densitometry, blood pressure, blood parameters, Mediterranean diet adherence, and physical activity levels.

RESULTS

After the lockdown, both healthy and unhealthy lifestyle groups showed a significant worsening of HDL, cholesterol/HDL lipids, and isometric knee extension strength parameters. However, individuals with an unhealthy lifestyle also showed a significant worsening in LDL lipids, Non-HDL lipids, bone mineral density of the femoral neck, fat mass/height (%), truncal fat mass (absolute and percentage), total fat mass (absolute and percentage) and handgrip strength.

CONCLUSIONS

The COVID-19 pandemic had a negative impact on the overall health status of Spanish older women, potentially increasing their susceptibility to comorbidities, such as lipid cholesterol, body fat, and decreased muscle strength.

Changes in Physical Activity Patterns Due to the Covid-19 Pandemic: A Systematic Review and Meta-Analysis

With the outbreak of the Corona Virus Disease 19 (Covid-19) in late 2019, governments increasingly imposed containment strategies, including social distancing as well as restricted population movement, potentially having negative impacts on mental and physical health. A growing number of studies have examined the impact of the pandemic on different facets of physical activity (PA); an overview combining these (mixed) results, however, is missing. Thus, the objective of this systematic review and meta-analysis was to investigate whether and to which extent PA changed from before to during the Covid-19 pandemic, taking age, gender, and measurement method into account. The literature search was conducted using PubMed, Web of Science, and Scopus. Results of the main characteristics were descriptively synthesized and analyzed in a meta-analysis quantifying effects of the pandemic on PA divided by age groups, with additional subgroup analyses of the characteristics age, gender, and measurement method being narratively synthesized. Overall, 57 studies with a total sample size of 119,094 participants (N between 10 and 60,560 subjects) from 14 countries worldwide with participants aged between four and 93 years were included. Thirty-two studies revealed a significant decline in PA, whereas only five studies found a significant increase in PA during the Covid-19 pandemic. Fourteen studies revealed mixed results. PA decreased in all age groups, independent of gender. Most self-reported and all device-based measurement methods showed a reduction in PA. However, effects were not found to be significant in all age groups. Nevertheless, the declining trend should be noted and governments should strive to enable PA within periods of pandemic restrictions, or promote alternatives such as digital training to avoid negative health consequences within the population.
