ABSTRACT

This paper evaluates the effects of economic shocks to current and expected income reduction on mental wellbeing. We use individual-level data from three East Asian countries; China, Japan, and South Korea, during the early phases of the pandemic when the COVID-induced economic shocks were severe. The findings reveal significant causal effects from current and expected income reduction on different aspects of mental health deterioration, including anxiety, trouble sleeping, boredom, and loneliness. Interestingly, we found that expectations of future income loss have a significantly larger effect on people's mental wellbeing compared to current falls in income. This has significant implications for the design of policies to support income during pandemics.

ABSTRACT

OBJECTIVE: Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and among the most common malignancies in young adults and requires a unique pattern of healthcare utilization including an acute/emergent presentation and an intensive initial 8 months of therapy followed by two years of outpatient treatment. The COVID-19 pandemic caused massive global disruptions in healthcare use and delivery. This report aims to examine the effects of the COVID-19 pandemic on the presentation, diagnosis and continued management of childhood and young adult ALL in regard to utilization and cost of care among commercially insured individuals in the United States. RESULTS: Utilizing a commercial insurance claims database, 529 pediatric and young adult patients were identified who were diagnosed with ALL between January 2016 and March 2021. New diagnoses were evaluated by era and demographics. Utilization was measured by COVID-related era as number of inpatient and outpatient encounters, inpatient days, and cumulative cost during the initial 8 months of therapy. None of these cost or utilization factors changed significantly during or shortly after the pandemic. These findings reinforce that the necessary care for pediatric and young adult ALL was unwavering despite the massive shifts in the healthcare system caused by the COVID-19 pandemic. This provides a valuable benchmark as we further examine the factors that influence the pandemic's impact on health equity and access to care, especially in vulnerable pediatric and young adult populations. This is the first investigation of the effect of the COVID-19 pandemic on utilization and cost of care in pediatric and young adult cancer.

ABSTRACT

BACKGROUND: Long COVID syndrome can have a major impact on life organization. Its persistent symptoms may cause a potentially disabling condition that affects the quality of life of those suffering from it. The resulting loss of functional independence hinders the ability to return to normal life. Many research studies carried out on this novel syndrome have focused on describing its extensive symptomatology. Studies on later repercussions, however, such as disability or loss of significant roles, remain scarce. This study examines the loss of socioemotional and occupational roles experienced by individuals suffering from Long COVID, as a result of the disease. A secondary objective is to analyze the sociodemographic and clinical factors associated with this loss of roles. PATIENTS AND METHODS: A cross-sectional study was conducted with the participation of 100 patients diagnosed with Long COVID, over the age of 18, and attended by Primary Health Care in the Autonomous Community of Aragon. The main study variable was the loss of significant socioemotional and occupational roles by the participants. Sociodemographic and clinical data were also collected through a structured interview. Subsequently, a descriptive, correlational, and regression-based statistical analysis was performed using the SPSS Statistics program. RESULTS: Based on the 100 study participants, the median number of roles lost was 3 (IQR 2) and the median number of valuable roles lost was 2 (IQR 2). More cognitive impairment and not having an active work role were predictors of a greater loss of valuables roles. CONCLUSION: Long COVID symptoms hinder the development of socioemotional and occupational roles. Healthcare professionals should consider this when intervening to ensure that their patients may recover their life as it was before the disease.

ABSTRACT

OBJECTIVES: In a sample of Mexican American adolescents (N = 398; 51% females; aged 13-17), we examined the associations between psychological distress, COVID-19 household economic stress, COVID-19 academic stress, and whether these associations varied by adolescents' gender and by parents/caregivers' essential worker status. METHOD: First, linear regression models assessed the main effects of household economic and academic stress on psychological distress. Second, the moderating effects of gender and parents/caregivers' essential worker status on the association between household economic and academic stress, and psychological distress were examined. Third, the three-way interaction effect of household economic stress, gender, and parents/caregivers' essential worker status on psychological distress as well as the three-way interaction effect of academic stress, gender, and parents/caregivers' essential worker status on psychological distress were calculated. RESULTS: Household economic and academic stress were associated with psychological distress. However, these associations did not vary based on adolescents' gender or parents/caregivers' essential worker status. The three-way interaction for household economic stress, parents/caregivers' essential worker status, and gender for psychological distress was significant. Specifically, the effects of household economic stress on psychological distress was worse for boys than girls whose parents/caregivers were essential workers. Furthermore, the three-way interaction among academic stress, parents/caregivers' essential worker status, and gender was significant. Particularly, the effects of academic stress when grades were worse on adolescents' psychological distress was worse for boys than girls whose parents/caregivers were essential workers. CONCLUSION: Parents/caregivers' essential worker status was salient among Mexican American adolescents' mental health outcomes during COVID-19, particularly for adolescent boys.

ABSTRACT

AIM OF THE STUDY: The present work is intended to give an overview of rehabilitation of patients with post COVID-19 condition covered by the German Pension Insurance in 2021. METHODS: Cross-sectional analysis of medical rehabilitation completed in 2021, in which COVID-19 sequelae were coded in first or second place in the uniform discharge report according to the International Statistical Classification of Diseases and Related Health Problems was carried out. The codes U08(.9), U09(.9) and U10(.9) as well as the corresponding codes from 2020 were taken into the evaluation as COVID-19-related diseases. Children's rehabilitation and oncological rehabilitation for pensioners and their relatives were excluded. Statistically, relative and absolute frequencies are given for nominal and ordinal variables, and median and quartiles for continuous, skewed distributed variables. RESULTS: 9,666 rehabilitations with one of the codes mentioned in first or second place remained. 54.8% of the patients were women and 43.2% men. The median age was 54 and 55 years (women/men). In all, 64.4% of the rehabilitations were carried out in the pulmonary medicine department. Owing to somatic indications, almost 50% of these patients in rehabilitation remained in the clinic beyond the regular approval period. The most common other diagnoses were diseases of the respiratory system. In 80.7% of those affected, the treating physicians considered the post-COVID-19 condition-associated symptoms as improved through rehabilitation. Furthermore, employment was subject to social security contributions for 88.0% of these patients, and 30.5% were employed in the fields of health, social affairs, teaching, and education. Of those affected, 63.8% were on sick leave when they were admitted, 63.0% when they were discharged. With regard to performance in the last job or on the general job market, over 90.0% received a prognosis for 6 hours and more. CONCLUSION: The importance of post-COVID-19 condition in the context of medical rehabilitation increased significantly over the course of 2021. The disease causes long periods of disability. With regard to performance, the available analyses give a positive picture; only 6.5% of those individuals undergoing rehabilitation were assessed as having a reduced capacity to earn of less than 3 hours on the general labor market.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has had major ramifications for health and the economy at both the individual and collective levels. This study examined exogenous negative changes in household income and their implications on psychological well-being (PWB) among the Chinese population during the COVID-19 pandemic. METHODS: Data were drawn from the early China COVID-19 Survey, a cross-sectional anonymous online survey administered to the general population in China. Self-reported PWB was measured using a 5-point Likert scale with five questions related to the participants' recent psychological state. Hierarchical multiple linear regression was employed to examine whether income loss during the COVID-19 pandemic was associated with poor psychological health. RESULTS: This study included 8,428 adults, of which 90% had suffered from a moderate or severe loss of household income due to the early COVID-19 pandemic. Those who had experienced moderate or severe loss of income scored significantly lower on psychological well-being than those who did not experience income loss (19.96 or 18.07 vs. 21.46; P < 0.001); after controlling for confounders, income loss was negatively associated with PWB scores (moderate income loss: B = - 0.603, P < 0.001; severe income loss: B = - 1.261, P < 0.001). An interaction effect existed between the degree of income loss and pre-pandemic income groups. Specifically, participants in the middle-income group who had suffered severe income loss scored the lowest on PWB (B = - 1.529, P < 0.001). There was also a main effect on income loss, such that participants with varying degrees of income loss differed across five dimensions, including anhedonia, sleep problems, irritability or anger, difficulty with concentration, and repeated disturbing dreams related to COVID-19. CONCLUSIONS: Income loss during the pandemic has had detrimental consequences on psychological well-being, and the magnitude of the impact of income loss on psychological well-being varied according to previous income levels. Future policy efforts should be directed toward improving the psychological well-being of the economically vulnerable and helping them recover from lost income in the shortest time possible.

ABSTRACT

Abstract Objective To assess the economic and professional impact (including teaching and training) during the covid-19 pandemic, as well as the prevalence of major depressive episode and generalized anxiety disorder, on shoulder and elbow surgeons in Brazil. Methods Cross-sectional study carried out with surgeons who are members of the Brazilian Society of Shoulder and Elbow Surgery (SBCOC). Sampling was non-probabilistic for convenience. The information was obtained through a self-administered online questionnaire, through the SBCOC members' registered e-mails, using structured questions and the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) instruments to screening for major depressive episode and generalized anxiety disorder, respectively. Results 119 participants were evaluated. The commitment in teaching was affirmed by 87.7% of the surgeons, there was a reduction above 50% of the surgical volume for about 4 out of 10 surgeons and reduction of the income above 50% for about 17.3%, due to the fact that 55.5% of professionals did not have professional stability. The major depressive episode had a prevalence of 26.7% in the sample, and generalized anxiety disorder was presented by 20% of the surgeons. Conclusion The combination of the negative impact on professional and financial factorsmay have affected shoulder and elbow surgeons in Brazil, generating high rates of anxiety and depression.

ABSTRACT

Poverty is an important social determinant of health that is associated with increased risk of death1-5. Cash transfer programmes provide non-contributory monetary transfers to individuals or households, with or without behavioural conditions such as children's school attendance6,7. Over recent decades, cash transfer programmes have emerged as central components of poverty reduction strategies of many governments in low- and middle-income countries6,7. The effects of these programmes on adult and child mortality rates remains an important gap in the literature, however, with existing evidence limited to a few specific conditional cash transfer programmes, primarily in Latin America8-14. Here we evaluated the effects of large-scale, government-led cash transfer programmes on all-cause adult and child mortality using individual-level longitudinal mortality datasets from many low- and middle-income countries. We found that cash transfer programmes were associated with significant reductions in mortality among children under five years of age and women. Secondary heterogeneity analyses suggested similar effects for conditional and unconditional programmes, and larger effects for programmes that covered a larger share of the population and provided larger transfer amounts, and in countries with lower health expenditures, lower baseline life expectancy, and higher perceived regulatory quality. Our findings support the use of anti-poverty programmes such as cash transfers, which many countries have introduced or expanded during the COVID-19 pandemic, to improve population health.

ABSTRACT

Background: The COVID-19 pandemic drives psychological distress. Previous studies have mostly focused on individual determinants but overlooked family factors. The present study aimed to examine the associations of individual and family factors with psychological distress, and the mediating effect of individual fear and the moderating role of household income on the above associations. Methods: We conducted a population-based cross-sectional survey on Chinese adults in Hong Kong from February to March 2021 (N = 2,251) to measure the independent variables of anti-epidemic fatigue, anti-epidemic confidence, individual and family members' fear of COVID-19, and family well-being (range 0-10), and the dependent variable of psychological distress (through four-item Patient Health Questionnaire, range 0-4). Results: Hierarchical regression showed that anti-epidemic fatigue was positively (ß = 0.23, 95% CI [0.18, 0.28]) while anti-epidemic confidence was negatively (ß = -0.29, 95% CI [-0.36, -0.22]) associated with psychological distress. Family members' fear of COVID-19 was positively (ß = 0.11, 95% CI [0.05, 0.16]) while family well-being was negatively (ß = -0.57, 95% CI [-0.63, -0.51]) associated with psychological distress. Structural equation model showed that individual fear mediated the above associations except for family well-being. Multi-group analyses showed a non-significant direct effect of anti-epidemic confidence and a slightly stronger direct effect of family well-being on psychological distress among participants with lower incomes, compared to those with higher incomes. Conclusion: We have first reported the double-edged effect of family context on psychological distress, with the positive association between family members' fear of COVID-19 and psychological distress fully mediated by individual fear and the negative association between family well-being and psychological distress moderated by income level. Future studies are warranted to investigate how the contagion of fear develops in the family and how the inequality of family resources impacts family members' mental health amid the pandemic.

ABSTRACT

OBJECTIVES: This study investigates race-ethnic differences among older non-Hispanic Black, non-Hispanic White, and Hispanic adults' financial, employment, and stress consequences of COVID-19. METHODS: We use data from the Health and Retirement Study, including the 2020 COVID-panel, to evaluate a sample of 2,929 adults using a combination of bivariate tests, OLS regression analysis, and moderation tests. RESULTS: Hispanic and non-Hispanic Black older adults experienced more financial hardships, higher levels of COVID-19 stress, and higher rates of job loss associated with COVID-19 relative to their Non-Hispanic White counterparts. Non-Hispanic Black and Hispanic adults reported significantly higher levels of COVID-19 resilience resources, yet, these resources were not protective of the consequences of COVID-19. DISCUSSION: Understanding how the experiences of managing and coping with COVID-19 stressors differ by race-ethnicity can better inform intervention design and support services.

ABSTRACT

COVID-19 unexpectedly ensnared the entire world and wreaked havoc on global economic and financial systems. The stock market is sensitive to black swan events, and the COVID-19 disaster was no exception. Against this backdrop, this study explores the impact of COVID-19 and economic policy uncertainty (EPU) on Chinese stock markets' returns for the period spanning January 23, 2020 to August 04, 2021. The outcomes of the novel quantile-on-quantile regression analysis revealed that both COVID-19 and EPU had a significant negative impact on both Shanghai and Shenzhen stock market returns, while COVID-19 aggravated the level of economic uncertainty in both financial markets. The quantile causality approach of Troster et al. (2018) validates our main estimations. We conclude that COVID-19 and a high level of EPU enervated the returns of China's leading stock markets. Our study provides key insights to policymakers and market participants to determine the behavior of China's stock market returns vis-à-vis COVID-19 during the peak of the pandemic and beyond. Specifically, our findings apprise portfolio investors to augment their portfolio diversification fronts.

ABSTRACT

Black Americans are more likely to be essential workers due to racial capitalism. Because of the COVID-19 pandemic, essential workers are less able to adhere to social distancing and stay-at-home guidelines due to the nature of their work, because they are more likely to occupy crowded households, and are more likely to possess pre-existing health conditions. To assist Black essential workers in preventing infection or reducing the intensity of symptoms if contracted, vaccination against the virus is essential. Unfortunately, Black essential workers face considerable barriers to accessing vaccinations and are hesitant to receive the vaccine due to widespread misinformation and justified historical mistrust of the American medical system. The purpose of this work is to (1) describe the disproportionate impact of COVID-19 on Black essential workers due to racial capitalism, (2) outline the socioeconomic and racial barriers related to vaccination within this population, and (3) to suggest policy-related approaches to facilitate vaccination such as access to on-site vaccination opportunities, the funding of community outreach efforts, and the mandating of increased employee benefits.

ABSTRACT

This study evaluates the sensitivity of government bond yields from the countries most affected by the COVID-19 pandemic to variations in some international risk factors during the period between January 2020 and April 2021. This sample period allows us to focus the study on the first, and the subsequent waves of the COVID-19 pandemic. Specifically, we propose an extended risk factor model estimated using the quantile regression approach. In addition, this study compares the COVID-19 pandemic period with a pre-pandemic and a post-vaccination period. Interesting differences among them are observed, remarking that gold is the key risk factor during the pandemic, whereas VIX and crude oil play that role in the pre-pandemic and the post-vaccination periods, respectively, mainly for bearish states. As expected, the explanatory power of the model is better at extreme quantiles, showing relevant differences between sensitivities, because the found effects are quantile-, country- and risk factor-dependent. The results during the pandemic are robust to the inclusion of a country-specific factor and a factor accounting for the mutual influence of the government bonds.
