Mental and physical health among the French population before and during the first and second COVID-19 lockdowns: Latent class trajectory analyses using longitudinal data

Associations of Dietary Diversity Trajectories with Frailty among Chinese Older Adults: A Latent Class Trajectory Analysis Based on a CLHLS Cohort

BACKGROUND

High dietary diversity has been found to be associated with frailty. However, the trajectory of dietary diversity intake in relation to frailty is unclear.

METHODS

Using the latent class trajectory modeling approach, we identified distinctive dietary variety trajectory groups among 2017 participants based on the Chinese Longitudinal Healthy Longevity Survey acquired at four time points within a 10-year period. Frailty status was assessed using a frailty index comprising 37 health deficits. Dietary diversity was quantified using the dietary variety score (DVS), based on food category consumption frequency. Logistic regression analyses were employed to explore the association between DVS change trajectories and frailty.

RESULTS

This study identified two distinct DVS trajectories: "Moderate-Slow decline-Slow growth", encompassing 810 (40.16%) individuals, and "Moderate-Slow growth-Accelerated decline", including 1207 (59.84%) individuals. After adjusting for covariates, the odds ratio for DVS in the "Moderate-Slow decline-Slow growth" group was 1.326 (95% confidence interval: 1.075-1.636) compared to the "Moderate-Slow growth-Accelerated decline" group. The "Moderate-Slow decline-Slow growth" trajectory continued to decrease and was maintained at a low level in the early stages of aging.

CONCLUSION

Sustaining a high dietary diversity trajectory over time, particularly in the early stages of aging, could potentially decrease the risk of frailty among older Chinese adults.

Income loss and subsequent poor psychological well-being among the Chinese population during the early COVID-19 pandemic

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.

Depression during the COVID-19 pandemic among people living with HIV: Are low HIV/AIDS stigma and high perceived emotional support protective resources?

This study has two objectives: first, to examine changes in depressive symptoms among people living with HIV (PLWH) during the COVID-19 pandemic and, second, to verify the role of HIV/AIDS stigma and perceived emotional support (PES) in the heterogeneity of these changes. The participants were 392 people with a medical diagnosis of HIV who have undergone antiretroviral therapy. Depression was measured at three time points with 6-month intervals using the Centre for Epidemiological Studies Depression Scale (CES-D). PES was evaluated with the Berlin Social Support Scales, and HIV/AIDS-related stigma was assessed with the Berger HIV Stigma Scale. Latent growth class modelling identified four trajectories of depression over the study period: three stable (very high, high, and very low) and one increasing. Both the very high and high stable trajectories had baseline values above the CES-D cut-off point for depression, suggesting that 57.6% of the sample was likely to be diagnosed with depression. After controlling for sociodemographic and clinical variables, stigma and PES were found to be significant covariates of the obtained trajectories; however, they did not protect against an increase in depression symptoms. There was no overall increase in depression symptoms among the PLWH participants during the pandemic, but this change in depression symptoms was heterogeneous. We observed the potential development of depression in initially well-functioning individuals despite their personal resources differing only slightly from those who remained resilient.

Psychosocial predictors of trajectories of mental health distress during the COVID-19 pandemic: A four-wave panel study

Previous research suggested that during the COVID-19 pandemic, mental distress did not affect all people equally. This longitudinal study aims to examine joint trajectories of depressive, anxiety, and stress symptoms in a sample of Italian adults during the pandemic, and to identify psychosocial predictors of distress states. We analyzed four-wave panel data from 3,931 adults who had received assessments of depressive, anxiety and stress symptoms between April 2020 and May 2021. Trajectories of individual psychological distress were identified by Latent Class Growth Analysis (LCGA) with parallel processes, and multinomial regression models were conducted to identify baseline predictors. Parallel process LCGA identified three joint trajectory classes for depression, anxiety and stress symptoms. Most individuals (54%) showed a resilient trajectory. However, two subgroups showed vulnerable joint trajectories for depression, anxiety and stress. Expressive suppression, intolerance to uncertainty, and fear of COVID-19 were risk characteristics associated with vulnerable trajectories for mental health distress. Moreover, vulnerability to mental health distress was higher in females, younger age groups and those unemployed during the first lockdown. Findings support the fact that group heterogeneity could be detected in the trajectories of mental health distress during the pandemic and it may help to identify subgroups at risk of worsening states.

The importance of mentalization, coping mechanisms, and perceived stress in the prediction of resilience of healthcare workers

Resilience is the process of overcoming stressors. Being able to examine the effect of the Covid epidemic on healthcare workers (HCWs) has provided us a unique opportunity to understand the impact of trauma on resilience. We aimed to investigate the relationship between stress, mentalization, and an individual's coping capacity against a real risk (Covid-19) and evaluate the predictors of resilience. 302 HCWs have enrolled in the study and completed an online questionnaire assessing demographics, perceived stress, resilience, coping, and mentalization. We utilized statistical analysis together with a Random Forest classifier to analyze the interaction between these factors extensively. We applied ten times ten-fold cross-validation and plotted Receiver Operator Characteristic (ROC) with the calculated Area Under the Curve(AUC) score and identify the most important features. Our experiments showed that the Perceived stress scale has the strongest relationship with resilience. The subject's awareness level of emotional states is an important factor that determines the level of resilience. Coping styles such as the decision of giving up is also a crucial indicator. We conclude that being aware of the risks and the mental states are the dominant factors behind the resilience levels of healthcare workers under pandemic conditions.

Shaped by the COVID-19 pandemic: Psychological responses from a subjective perspective-A longitudinal mixed-methods study across five European countries

BACKGROUND

Contextual factors are essential for understanding long-term adjustment to the COVID-19 pandemic. Therefore, the present study investigated changes in mental health outcomes and subjective pandemic-related experiences over time and across countries. The main objective was to explore how psychological responses vary in relation to individual and environmental factors.

METHODS

The sample consisted of N = 1070 participants from the general population of Austria, Croatia, Georgia, Greece, and Portugal. We applied a longitudinal mixed-methods approach, with baseline assessment in summer and autumn 2020 (T1) and follow-up assessment 12 months later (T2). Qualitative content analysis by Mayring was used to analyse open-ended questions about stressful events, positive and negative aspects of the pandemic, and recommendations on how to cope. Mental health outcomes were assessed with the Adjustment Disorder-New Module 8 (ADNM-8), the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5), the Patient Health Questionnaire-2 (PHQ-2), and the 5-item World Health Organization Well-Being Index (WHO-5). The analyses were performed with SPSS Statistics Version 26 and MAXQDA 2022.

RESULTS

The mental health outcomes significantly differed over time and across countries, with e.g. Greek participants showing decrease in adjustment disorder symptoms (p = .007) between T1 and T2. Compared with other countries, we found better mental health outcomes in the Austrian and the Croatian sample at both timepoints (p < .05). Regarding qualitative data, some themes were equally represented at both timepoints (e.g. Restrictions and changes in daily life), while others were more prominent at T1 (e.g. Work and finances) or T2 (e.g. Vaccination issues).

CONCLUSIONS

Our findings indicate that people's reactions to the pandemic are largely shaped by the shifting context of the pandemic, country-specific factors, and individual characteristics and circumstances. Resource-oriented interventions focusing on psychological flexibility might promote resilience and mental health amidst the COVID-19 pandemic and other global crises.

Longitudinal impact of the COVID19 pandemic on mental health in a general population sample in France: Evidence from the COMET Study

BACKGROUND

To study the longitudinal impact of co-occurring mental health problems, and to identify vulnerable groups in need of mental health support during the COVID-19 pandemic.

METHODS

Analyses were based on data from 681 French participants in the international COVID-19 Mental Health Study, collected at four times (05/2020-04/2021). Symptoms of depression, anxiety and post-traumatic stress disorder (PTSD) were assessed using the Patient Health Questionnaire 9, the Generalized Anxiety Disorder-7 and the PTSD Check List for DSM-5. We performed k-means for longitudinal data to build trajectories of adults' depression, anxiety and PTSD symptoms and identify subgroups psychologically vulnerable. We then assessed whether mental health trajectories were predicted by lockdown regulations.

RESULTS

A high and a low cluster of mental health scores were identified. In both groups, mental health scores varied significantly across time. Levels of all mental health scores were lowest when COVID-19-related restrictions were lifted and highest when restrictions were in place, except for PTSD. No scores returned to the previous level or the initial level of mental health (p < 0.05). Participants with high levels of symptoms were characterized by younger age (OR: 0.98, 95 % CI: 0.97-0.99), prior history of mental disorders (OR: 3.46, 95 % CI: 2.07-5.82), experience of domestic violence (OR: 10.54, 95 % CI: 1.54-20.68) and medical issues (OR: 2.16, 95 % CI: 1.14-4.03).

LIMITATIONS

Pre-pandemic data were not available and the sample was recruited mainly by snowball sampling.

CONCLUSION

This study revealed subtle differences in the evolution of symptom trajectories during the first year of the Covid-19 pandemic, and highlighted several characteristics associated with the two clusters.

Does the practice of mindfulness reduce somatic symptoms and COVID-19-related anxiety? A community-based survey

Objective

Since the beginning of COVID-19 pandemic, several studies have shown an increase of psychological distress in the general population. Previous research demonstrated that high levels of anxiety are associated with reporting more somatic symptoms. The ability to adaptively regulate emotions is essential to deal with stressful situations, and it is one of the main components of mindfulness practice. The aim of the present study was to document the effect of mindfulness practice on somatic symptoms and psychological distress in the context of COVID-19 pandemic.

Methods

The study has a descriptive cross-sectional design. During the second wave of COVID-19 pandemic, between November 2020 and January 2021 participants living in France responded to an online survey on the impact of COVID-19 on psychological distress and physical health. The questionnaire included the assessment of COVID-19-related anxiety, mindfulness practice and experience, dispositional mindfulness, somatization, depression, generalized anxiety, and emotion regulation.

Results

A total of 569 people (mean age = 39.8 years, 90% women) were included in the study. COVID-19 related anxiety was associated with higher levels of somatic symptoms, generalized anxiety, and depression. About half of the sample (n = 318, 56%) reported moderate to severe somatic symptoms that were associated with higher levels of depression and anxiety, lower levels of dispositional mindfulness and to the use of maladaptive emotion regulation strategies. Overall, 164 subjects (28.8%) reported practicing meditation. No differences were found in dispositional mindfulness (MAAS score) between beginners and advanced practitioners, regardless of the type, years, frequency, and length of practice. Participants with less experience in mindfulness practice reported a significant higher number of somatic symptoms than non-practitioners and a higher use of rumination. Moreover, mindfulness experience was associated with the use of more adaptive emotion regulation strategies.

Conclusion

Mindfulness meditation has been promoted as a practice enhancing well-being and helping to cope with the psychological impact of stressful events. However, in a distressing situation as COVID-19 pandemic, a limited experience in mindfulness practices might result in the development or endurance of somatic symptoms. Adequate training and a focus on mindful acceptance, may contribute to enhance the effectiveness of mindfulness practice.

Mental Health Symptoms of University Students 15 Months After the Onset of the COVID-19 Pandemic in France

IMPORTANCE

The Conséquences de la pandémie de COVID-19 sur la santé mentale des étudiants (COSAMe) survey was conducted among university students in France during the COVID-19 pandemic and found that although there was a slight decrease in anxiety, depression, and stress between the first lockdown (T1) and 1 month after it ended (T2), the prevalence of suicidal ideation had increased between these periods and 1 in 5 students had probable posttraumatic stress disorder (PTSD) at T2. These results emphasize the need to explore the long-term consequences of the COVID-19 pandemic.

OBJECTIVES

To measure the prevalence of mental health symptoms among university students in France 15 months after the first lockdown (T3) and to identify factors associated with outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study reports data from the third measurement time of the repeated COSAMe survey, which took place from July 21 to August 31, 2021, through an online questionnaire sent to all French university students.

MAIN OUTCOMES AND MEASURES

The prevalence of suicidal thoughts, PTSD (PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition] [PCL-5]), stress (Perceived Stress Scale), anxiety (State-Trait Anxiety Inventory), and depression (Beck Depression Inventory) at T3 were gender- and degree-standardized and compared with prevalence rates at T1 and T2. Multivariable logistic regression analyses identified risk factors.

RESULTS

A total of 44 898 students completed the questionnaires. They were mainly women (31 728 [70.7%]), and the median (IQR) age was 19 (18-21) years. Standardized prevalence rates of stress, anxiety, depression, suicidal thoughts, and PTSD were 20.6% (95% CI, 20.2%-21.0%), 23.7% (95% CI, 23.3%-24.1%), 15.4% (95% CI, 15.1%-15.8%), 13.8% (95% CI, 13.5%-14.2%), and 29.8% (95% CI, 29.4%-30.2%), respectively. Compared with the decreased prevalence rates at T2, there was an increase at T3 for stress (2.5% increase), anxiety (13.9% increase), and depression (22.2% increase). The prevalence of suicidal ideation continued to increase from T1 (10.6%) to T3 (13.8%), and the prevalence of probable PTSD increased from 1 in 5 students to 1 in 3 students between T2 and T3. Female and nonbinary participants; participants without children and living in an urban area; and those with financial difficulties, a chronic condition, psychiatric history, COVID-19 history, social isolation, and low perceived quality of information received were at risk of all poor outcomes at T3 (eg, stress among women: adjusted OR, 2.18; 95% CI, 2.05-2.31; suicidal thoughts among nonbinary respondents: adjusted OR, 5.09; 95% CI, 4.32-5.99; anxiety among students with children: adjusted OR, 0.68; 95% CI, 0.56-0.81; depression among students living in a rural area: adjusted OR, 0.80; 95% CI, 0.75-0.85).

CONCLUSIONS AND RELEVANCE

These results suggest severe long-lasting consequences associated with the pandemic on the mental health of students. Prevention and care access should be a priority.

Trajectories of resilience and mental distress to global major disruptions

The COVID-19 pandemic has resulted in a major societal disruption, raising the question of how people can maintain or quickly regain their mental health (i.e., be resilient) during such times. Researchers have used the pandemic as a use case for studying resilience in response to a global, synchronously starting, and chronic set of stressors on the individual and societal level. Our review of this recent literature reveals that mental distress trajectories during the pandemic largely resemble mental distress responses to individual-level macro-stressors, except for a lower prevalence of recovery trajectories. Results suggest more resilient responses in older adults, but trajectories are less consistent for younger and older ages compared with middle-aged adults. We call for more research integrating state-of-the-art operationalizations of resilience and using these to study resilience over the lifespan.

Working from home during COVID-19 in a Danish hospital research setting: experiences of researchers and healthcare providers, explored by Group Concept Mapping

OBJECTIVES

The COVID-19 pandemic has changed the working environment, how we think of it and how it stands to develop into the future. Knowledge about how people have continued to work on-site and adjusted to working from home during the COVID-19 lockdown will be vital for planning work arrangements in the post-pandemic period. Our primary objective was to investigate experiences of working from home or having colleagues working from home during a late stage of the COVID-19 lockdown among researchers and healthcare providers in a hospital research setting. Second, we aimed to investigate researchers' productivity through changes in various proxy measures during lockdown as compared with pre-lockdown.

DESIGN

Mixed-method participatory Group Concept Mapping (GCM).

SETTING AND PARTICIPANTS

GCM, based on a mixed-method participatory approach, was applied involving researchers' and healthcare providers' online sorting and rating experiences working from home during the COVID-19 pandemic. At a face-to-face meeting, participants achieved consensus on the number and labelling of domains-the basis for developing a conceptual model.

RESULTS

Through the GCM approach, 47 participants generated 125 unique statements of experiences related to working from home, which were organised into seven clusters. Using these clusters, we developed a conceptual model that illustrated the pros and cons of working from home.

CONCLUSION

The future work setting, the role of the office and the overall work environment need to respond to workers' increased wish for flexible work arrangements and co-decision.

Trajectories of loneliness, depressive symptoms, and anxiety symptoms during the COVID-19 pandemic in Austria

Objective

There is considerable heterogeneity within populations regarding the effects of the COVID-19 pandemic on mental health. This study aimed at identifying latent groups of individuals within the older Austrian population that differ in their mental health trajectories across three phases of the pandemic.

Study design

Data were gathered from a longitudinal survey study among a sample of older adults in Austria. The survey was carried out in May 2020 (N₁ = 556), March 2021 (N₂ = 462), and December 2021 (N₃ = 370) via either computer-assisted web or telephone interviewing.

Methods

Latent class growth analysis was conducted to explore different homogenous groups in terms of non-linear trajectories of loneliness, depressive symptoms, and anxiety symptoms as well as potential correlates thereof.

Results

We identified four latent classes. The vast majority of individuals belong to two classes that are either resilient (71%) or that have recovered relatively quickly from an initial COVID-19 shock (10.2%). Deterioration in mental health after the first phase of the pandemic (13.4%) or a generally high mental health burden (5.4%) characterizes the other two classes.

Conclusions

About 19% of individuals showed increasing or elevated levels in loneliness, depressive symptoms, and anxiety symptoms across the COVID-19 pandemic. The feeling of being socially supported and in control over one's own life emerged as potentially protective factors.

Narratives of the worst experiences associated with peritraumatic distress during the COVID-19 pandemic: a mixed method study in the USA and Italy

Background: Although symptoms of posttraumatic stress disorder (PTSD) have been associated with the COVID-19 pandemic experiences, no study has explored yet the association of specific COVID-19 narratives with peritraumatic distress, the precursor of PTSD. Objective: To explore the worst experiences associated with peritraumatic distress during the first wave of the COVID-19 pandemic. Method: Adult residents (N = 1098), from the US (n = 741) and Italy (n = 357), completed an online survey including socio-demographic data, COVID-19-related experiences, the Peritraumatic Distress Inventory and an open question on their worst experiences during the first period of the COVID-19 pandemic (April-May 2020). A thematic content analysis (TCA) was conducted on the answers to the open question and a classification and regression tree (CART) analysis was used to identify the themes that best predicted the clinical levels of peritraumatic distress. Results: The main TCA themes related to participants' worst COVID-19 experiences were anxiety, threat, loss, anger, stress and constriction. Threat was the most prevalent theme and correlated with experiences such as being quarantined, being infected and a loved one receiving the diagnosis. US participants' descriptions of their worst experiences related more to life-threat and loss, while Italians reported more threat to the world, stress, social isolation, and feeling trapped. In the CART analysis, the main predictor (79.9%) was perceiving negative effects from the COVID-19 crisis. Among them, a COVID-related threat to self-experience was the most robust predictor. In its absence, being deprived of resources or experiencing high levels of anxiety were other robust predictors. Conclusions: The study provided evidence of the utility of a mixed-method approach in conceptualizing experiences associated with the COVID-19 pandemic and the risk of traumatic symptoms. Its findings may inform healthcare interventions and policies for tackling the new challenges posed by the COVID-19 pandemic. HIGHLIGHTS Clinically significant levels of peritraumatic distress symptoms were prevalent during the COVID-19 pandemic.Clinically significant levels of peritraumatic distress during the COVID-19 pandemic were related to experiences of life-threat, resource deprivation, and anxiety, cross-cutting the themes articulated by the thematic content analysis of anxiety, threat, loss, anger, stress and constriction.The US and Italian participants' descriptions of their worst experiences differed in subtle but important ways, with Americans reporting more life-threat and losses compared to Italians reporting more threat to the world, stress, social isolation, and feelings of being trapped.
