The General Public's Perceptions of How the COVID-19 Pandemic Has Impacted the Elderly and Individuals with Intellectual Disabilities.

This study examined the general public’s perceptions of how the COVID-19 pandemic has impacted the elderly and people with intellectual disabilities as well how these perceptions relate to people’s level of familiarity and contact quality with these groups. A cross-sectional survey was administered to a sample of the Dutch population (n = 1458 and n = 1761, comprising questions related to the elderly and people with intellectual disabilities, respectively). The general public was found to be generally aware of the deleterious impact of the pandemic upon the elderly and people with intellectual disabilities. Specifically, the respondents reported that both groups’ quality of life, physical and mental health, and quality and frequency of social contact was lower than it was prior to COVID-19, in addition to perceiving them as lonelier and less self-reliant. Notably, the impact on the elderly was considered to be greater than that on people with intellectual disabilities. Furthermore, those who had no familiarity with people with intellectual disabilities in real life perceived the impact to be lower than those who had a greater degree of familiarity. These findings have important implications, both for increasing awareness of the pandemic’s negative impact on these vulnerable groups and in terms of sufficiently addressing their specific needs and concerns. The findings also underscore that, particularly during the COVID-19 pandemic, it is important to increase the visibility of groups who already relied more on help and support from others in society prior to the pandemic, such as the elderly and people with intellectual disabilities, via, among other things, self-advocacy, education, and enhanced intergroup contact, in order to be able to sufficiently address their needs during these challenging times.

The medium-term consequences of a COVID-19 lockdown on lifestyle among Spanish older people with hypertension, pulmonary disease, cardiovascular disease, musculoskeletal disease, depression, and cancer.

This study investigated the associations of chronic diseases with changes in lifestyle and health behaviours in older people following the coronavirus disease 2019 (COVID-19) lockdown in Spain and compared the differences in changes over time. 1,092 participants (80.3±5.6 years; 66.5% female) from 2 Spanish cohorts were included. Telephone-based questionnaires were conducted to evaluate lifestyle and health risk behaviours at the end of lockdown and 7 months post-lockdown. Participants were classified as having physician-diagnosed chronic diseases based on self-reported data. Cox proportional models adjusted for major confounders were used. Compared to those without the corresponding chronic diseases, older people with hypertension were less likely to report increased alcohol consumption (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.55 to 0.99). Pulmonary diseases were associated with lower risks of increased sedentary time (HR, 0.58; 95% CI, 0.39 to 0.86) and worsened sleep quality (HR, 0.56; 95% CI, 0.36 to 0.87), while cardiovascular diseases were associated with a lower risk of decreased sedentary time (HR, 0.58; 95% CI, 0.38 to 0.88). Depression was linked to a higher likelihood of improved diet quality (HR, 1.53; 95% CI, 1.00 to 2.36). Cancer pacients were less likely to have worsened sleep quality (HR, 0.44; 95% CI, 0.22 to 0.89) but more likely to have reduced their frequency of social contact (HR, 2.05; 95% CI, 1.05 to 3.99). Older people with chronic diseases showed beneficial changes in lifestyle and health risk behaviours after the COVID-19 lockdown. In particular, older people with hypertension, pulmonary disease, and cancer tended to make beneficial lifestyle and health behaviour changes. However, older people with cardiovascular disease and depression engaged in more health risk behaviours.

Mortality Rate Differentiation in Russia in 2019-2020: COVID-19 Pandemic and Other Factors

The aim of the work is to find the factors that caused the differences in the change in the mortality rate in the regions caused by the pandemic. Using the data of official statistics and the results of regionally representative data of sample socio-demographic surveys of Rosstat, the authors attempt to achieve the goal by methods of both demographic and statistical analysis. The analysis showed that a significant part of the variation of regions in terms of mortality growth is explained by the characteristics of the demographic structure of the region (a high proportion of elderly people in the region, a large household size, the proportion of people with cancer in the region), as well as high population density and frequency of social contacts (especially in large cities). It was noteworthy that there was no significant impact on the regional differentiation of mortality from the availability of medical services and the scale of health infrastructure, which apparently indicates that in 2020 the probability of dying from COVID-19 or concomitant complications did not depend much on the actions of doctors and the equipment of hospitals. The paper also highlights the problem of imperfection of the research information base in terms of the selection of objective indicators and methods for analyzing the contribution of the COVID-19 epidemic to the level and dynamics of mortality.

Depressive symptoms among older empty nesters in China: the moderating effects of social contact and contact with one’s children

Objectives Mental health for older people has become a major social concern. Literature has shown that older people, especially when they become empty nesters—when a parent lives alone or lives with his/her spouse after the youngest child leaves home—may start to develop various mental health problems due to reduced contacts with their children. Using fixed-effects, multivariate regression with a difference-in-differences approach and propensity score matching, this paper examines the relationship between being an empty nester and mental health among older people in China, and the moderating effects of social contact and contact with one’s children in terms of mental health. Our data come from the China Health and Retirement Longitudinal Study of 2011, 2013, 2015 and 2018. Results We found that, in the short term, the mental health of older people may not be affected after they became empty nesters. But in the longer term, if they did not have regular contact with their children, their mental health would deteriorate with time. Social contact, especially cognitive activities, was beneficial to the mental health of the older empty nesters. We also found that for older empty nesters with disabilities, frequent social contact and contact with their children were more important. Conclusion We urge the government to promote community-based social activities for older people, especially for those with functional limitations.

Effect of COVID-19 driven lockdown on social contact pattern in Puducherry, India: A longitudinal study.

This study was undertaken to assess the change in social contact and transmission dynamics among adults in the Puducherry district during the different phases of country-wide lockdown. Adults aged 18-69 years in Puducherry were assessed for frequency and duration of contacts in the following time points: prior to lockdown (March 2020), during lockdown, immediate post-lockdown (April, June 2020), and seven months post-lockdown (February 2021). Adjusted incidence rate ratios (aIRR) were obtained using a generalized estimating equation. We also assessed the exponential trajectory of the time-varying reproduction number (Rt) during and after lockdown. Compared to pre-lockdown phase, frequency of social contacts during 1st week, 4th week of lockdown, and immediate post-lockdown were reduced by 89% (aIRR = 0.11; 95% CI: 0.09-0.13), 40% (aIRR = 0.60; 95% CI: 0.52-0.69) and 91% (aIRR = 0.09; 95% CI: 0.07-0.10) respectively. However, the decline was not statistically significant at seven months post-lockdown. Correspondingly, we observed an initial spike in Rt during the lockdown phase followed by a gradual decline during the immediate post-lockdown phase. However, seven months post-lockdown, Rt has increased again. The study showed high compliance to the lockdown measures in Puducherry during the lockdown and immediate post-lockdown periods. However, as the lockdown measures were relaxed, the contact rate returned to the pre-lockdown state.

Interim Estimate of Vaccine Effectiveness of BNT162b2 (Pfizer-BioNTech) Vaccine in Preventing SARS-CoV-2 Infection Among Adolescents Aged 12-17 Years - Arizona, July-December 2021.

The BNT162b2 (Pfizer-BioNTech) mRNA COVID-19 vaccine has demonstrated high efficacy in preventing infection with SARS-CoV-2 (the virus that causes COVID-19) in randomized placebo-controlled Phase III trials in persons aged 12-17 years (referred to as adolescents in this report) (1); however, data on real-word vaccine effectiveness (VE) among adolescents are limited (1-3). As of December 2021, the Pfizer-BioNTech vaccine is approved by the Food and Drug Administration (FDA) for adolescents aged 16-17 years and under FDA emergency use authorization for those aged 12-15 years. In a prospective cohort in Arizona, 243 adolescents aged 12-17 years were tested for SARS-CoV-2 by reverse transcription-polymerase chain reaction (RT-PCR) each week, irrespective of symptoms, and upon onset of COVID-19-like illness during July 25-December 4, 2021; the SARS-CoV-2 B.1.617.2 (Delta) variant was the predominant strain during this study period. During the study, 190 adolescents contributed fully vaccinated person-time (≥14 days after receiving 2 doses of Pfizer-BioNTech vaccine), 30 contributed partially vaccinated person-time (receipt of 1 dose or receipt of 2 doses but with the second dose completed <14 days earlier), and 66 contributed unvaccinated person-time. Using the Cox proportional-hazards model, the estimated VE of full Pfizer-BioNTech vaccination for preventing SARS-CoV-2 infection was 92% (95% CI=79%-97%), adjusted for sociodemographic characteristics, health information, frequency of social contact, mask use, location, and local virus circulation. These findings from a real-world setting indicate that 2 doses of Pfizer-BioNTech vaccine are highly effective in preventing SARS-CoV-2 infection among Arizona adolescents. CDC recommends COVID-19 vaccination for all eligible persons in the United States, including persons aged 12-17 years.

Loneliness During COVID-19 and Modes of Social Contact Use Among Older Adults

Due to social distancing and isolation recommendations, COVID-19 resulted in older adults’ greater reliance on technology to contact friends and families. While the mental health of older adults during COVID-19 has been well explored, less is known about how changes in modes and frequency of social contact is associated with loneliness. Using the National Health and Aging Trends Study COVID-19 data, this study assessed how the frequency of varying modes of contact (e.g., phone/email/text, in-person visits, videocalls) during the pandemic was associated with feelings of loneliness during COVID-19 among community-dwelling Medicare beneficiaries (n = 2149). Participants were asked if they felt lonely "more often," "less often," or "about the same" compared to before the outbreak started. Multinomial regression analyses indicated that, compared to those who reported daily in-person visits, the odds of having more feelings of loneliness as compared to about the same as pre-COVID-19 was significantly higher among those who reported having in-person visits a few times (OR=2.17,CI=1.08-4.36), at least once (OR=2.37,CI=1.11-5.04), and never/less than once a week (OR=3.37, CI=1.59-7.16) while controlling for demographics, household, and social network size. Compared to daily use, use of phone/email/text at least once (OR=0.44, CI=0.201-0.965) or a few times (OR=0.76,CI=0.58-0.99) a week was associated with lower odds of reporting more feelings of loneliness versus about the same. Results suggest that greater use of technology that promote social engagement improves social connectedness and decreases COVID-19 related loneliness among older adults, and highlights the importance of older adults’ access to technology, including reliable internet.

Can changes in social contact (frequency and mode) mitigate low mood before and during the COVID-19 pandemic? The I-CONECT project.

The coronavirus disease 2019 (COVID-19) global outbreak allowed a natural experiment to observe how older adults changed social patterns and how it affected their emotional well-being. We studied the frequency and modes of social contact and their effects on older adults' mood before and during the COVID-19 pandemic. Phone-based surveys were administered weekly before and during the COVID-19 pandemic. Participants were recruited from Portland, Oregon, and Detroit, Michigan. Older adults ≥75 years old (n= 155, age=81.0 ± 4.5, 72.3% women) were included in a randomized controlled trial, the Internet-Based Conversational Engagement Clinical Trial (I-CONECT). Low mood was self-reported as feeling downhearted or blue for three or more days in the past week. Social contact was self-reported by the amount of time spent in interactions, with whom (family, friends, others), and via which modes (in-person, phone/video call, text/email/letter). A total of 5525 weeks of data were derived from 155 participants. Before the COVID-19 pandemic, average social interaction time spent in-person, on phone/video call, and via text/email/letter was 406, 141, and 68 min/week, respectively. During the COVID-19 pandemic, time spent in-person was reduced by 135 min/week, while time spent via phone/video call and writing increased by 33 and 26 mins/week, respectively. In-person family contact was associated with less low mood regardless of the pandemic (odds ratio=0.92, p < 0.05). There was a COVID-19 × text/email/letter with friends interaction (odds ratio=0.77, p=0.03), suggesting that during the COVID-19 pandemic, an increase of 1 h of writing with friends per week was associated with a 23% decrease in the likelihood of experiencing low mood. The lost in-person time relating to COVID-19 restrictions tended to be partially compensated for with increased calls and writing time, although overall social interaction time decreased. During the COVID-19 pandemic, at least two types of social interactions (writing to friends and in-person family time) showed promise for mitigating low mood for older adults with limited social resources.

Multi-Year Spatial Variability of the Impact of Sociodemographic, Behavioural, and Health Factors on Depression of Older Adults

Abstract. The mental health of older adults has become a critical issue with the rising suicide rate in older adults in South Korea. Various factors related to depression can make heterogeneous impacts in different regions. Yet, such spatial perspectives have been rarely integrated with the mental health studies in South Korea. This study aims to explore 1) how differently each factor of sociodemographic characteristics, social interactions, and health-related behaviors is associated with depression of older adults throughout different regions in South Korea, and 2) how those relationships change across five survey years (2008–2016) for a long term. Spatially local regression and small-multiple map visualization were applied to analyze a longitudinal panel survey dataset named KLoSA, collected in South Korea. It is found that age, marital status, in-person social contact frequency, and perceived physical health are significantly correlated with depression in more regions than other variables. The local regression coefficients and significance vary by region and year.

Type and frequency of social contacts associated with low mood before and during the COVID-19 pandemic in older adults: I-CONECT project.

BackgroundSocial isolation is a risk factor for dementia, but the underlying mechanism is not well understood. It is possible that lack of social contacts negatively affects emotional well‐being, which leads to cognitive decline. To shed light on this potential mediation mechanism, we examined changes in type and frequency of social contacts and their effects on mood using data collected before and during the COVID‐19 pandemic among socially isolated older adults aged 75 and older.MethodThe data come from an ongoing randomized controlled trial, the Internet‐Based Conversational Engagement Clinical Trial (I‐CONECT, ClinicalTirals.gov: NCT02871921). One hundred forty‐six participants (age=81.0±4.5, 71.9% women) who were in the trial both before and during the pandemic and whose data were available as of November of 2020 were included in the current analysis. Weekly health questionnaires administered on all participants regardless of treatment assignments were collected before and during the COVID‐19 pandemic. Low mood (“Blueness”) was self‐reported as feeling downhearted or blue for three or more days in the past week (YES/NO). Social contacts were self‐reported by amount of time they had interacted, with whom (family; friends; others), and via which modalities (in‐person; phone/video call; text/email).ResultA total of 4,774 weeks of survey data were analyzed (3,047 before COVID 19). The weekly average time spent in‐person, on phone/video call, and via text/email were 282, 113, and 44 minutes, respectively. During the COVID‐19 pandemic, participants on average spent 82 minutes less in total social contact per week (in‐person: reduced 123 minutes, video/call: increased 28 minutes, text/email: increased 13 minutes per week). Generalized estimating equation model revealed that in‐person family contact was associated with less blueness regardless of the pandemic (OR=0.91, p=0.04). There was a COVID*text/email time with friends interaction (OR=0.68, p=0.03), suggesting that during the COVID‐19 pandemic, an increase of 1 hour of texting/emailing with friends per week was associated with 32% decrease in experiencing blueness three or more days per week.ConclusionIn‐person family time is beneficial for mental health. While in‐person contacts become less frequent during the COVID‐19 pandemic, increased text/email time with friends becomes an alternative to maintain mental health for socially isolated older adults.

Mental, Physical and Social Functioning in Independently Living Senior House Residents and Community-Dwelling Older Adults.

Senior houses provide social interaction and support, potentially supporting older people’s physical and mental functioning. Few studies have investigated functioning of senior house residents. The aim was to compare functioning between senior house residents and community-dwelling older adults in Finland. We compared senior house residents (n = 336, 69% women, mean age 83 years) to community-dwelling older adults (n = 1139, 56% women, mean age 74 years). Physical and mental functioning were assessed using the SF 36-Item Health Survey. Loneliness and frequency of social contacts were self-reported. The analyses were adjusted for age, socioeconomic factors and diseases. Physical functioning was lower among men in senior houses compared to community-dwelling men (mean 41.1 vs. 46.4, p = 0.003). Mental functioning or the frequency of social contacts did not differ between type of residence in either sex. Loneliness was higher among women in senior houses compared to community-dwelling women (OR = 1.67, p = 0.027). This was not observed in men. Results suggest that women in senior houses had similar physical and mental functioning compared to community-dwelling women. Male senior house residents had poorer physical functioning compared to community-dwelling men. Women living in senior houses were lonelier than community-dwelling women despite the social environment.

Quality over quantity? The role of social contact frequency and closeness in suicidal ideation and attempt

BackgroundSocial support has been identified as a protective factor against suicidal thoughts and behaviors. Research has not conclusively identified the component of social support most implicated in suicidal thoughts and behaviors: (1) frequency of social contact or (2) closeness of relationships. This study examined the relationships between these facets of social support and suicidal thoughts and behaviors in two nationally representative samples, as well as subsamples with social anxiety disorder (SAD). MethodsStudy 1 variables for lifetime and past-year suicide ideation and attempt, social contact frequency, and closeness were calculated and examined within the National Comorbidity Survey-Replication (NCS-R). Study 2 examined the independent contributions of social contact frequency and closeness to only lifetime suicide attempt in the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III). ResultsIn the NCS-R, lower social closeness but not contact frequency was uniquely associated with suicidal ideation and attempt in the general sample and those with SAD. In the NESARC-III, both components of social support were associated with lifetime suicide attempt in the general sample, while only social closeness was uniquely associated with suicide attempt in the SAD subsample. LimitationsThis study utilized cross-sectional data and was limited in the validity and specificity of the variables assessed. DiscussionLower social closeness was more strongly associated with suicidality than social contact frequency and merits attention as a potential target for suicide-related interventions. Social closeness may be especially relevant in populations experiencing high rates of suicidal thoughts and behaviors and decreased social support.

Effectiveness of Resource Groups for Improving Empowerment, Quality of Life, and Functioning of People With Severe Mental Illness

Although the importance of recovery-oriented care for people with severe mental illness (SMI) is widely acknowledged, essential elements such as personalization and involvement of significant others are not adequately implemented in practice. To determine whether using resource groups (RGs) within flexible assertive community treatment (FACT) has favorable effects on empowerment and recovery-related outcomes in people with SMI. This assessor-blind, multisite randomized clinical trial was conducted from September 1, 2017, to September 30, 2020, with follow-up at 9 and 18 months. A total of 158 participants aged 18 to 65 years meeting the criteria for SMI were randomly allocated to FACT plus RG vs FACT as usual (1:1) in 20 FACT teams throughout the Netherlands. Data were analyzed from September 1, 2020, to January 31, 2021. The study was prespecified in the trial protocol and data from the intent-to-treat population were analyzed. In the FACT plus RG condition, patients chose members from their informal and formal networks to form an RG that meets quarterly to discuss self-formulated recovery goals. The RG was integrated into the multidisciplinary support provided by the FACT team. In the FACT as-usual condition, empowerment (defined as overcoming powerlessness and gaining control of one's life) and involvement of significant others was also part of the provided care, but without the structure of the RG. The primary outcome was self-reported empowerment, measured with the Netherlands Empowerment List. A total of 158 participants with SMI (median age, 38 [median absolute deviation, 13] years; 93 men [58.9%]) were randomized to FACT plus RG (n = 80) or FACT as usual (n = 78) care. Intention-to-treat analyses showed that randomization to the RG condition was associated with a clinically significant increase in empowerment (Cohen d, 0.54; 95% CI, 0.21-0.86) and improved outcomes with small to medium effect sizes in terms of quality of life (Cohen d, 0.25; 95% CI, -0.07 to 0.56), personal recovery (Cohen d, 0.38; 95% CI, 0.06-0.69), quality of social contact (Cohen d, 0.24; 95% CI, -0.07 to 0.56), disability (Cohen d, 0.29; 95% CI, -0.03 to 0.60), general functioning (Cohen d, 0.30; 95% CI, -0.01 to 0.62), and social functioning (Cohen d, 0.28; 95% CI, -0.04 to 0.59). No differences between conditions were found regarding psychopathological symptoms, attachment, frequency of social contact, and employment. Compared with FACT as usual, participants who stayed with the assigned treatment in the RG condition were more satisfied with treatment at 9 (Cohen d = 0.45; t135 = -2.62; P = .009) and 18 (Cohen d = 0.41; t116 = -2.22; P = .02) months. These findings show that working with RGs improves empowerment and other mental health outcomes in people with SMI who receive community-based mental health services. This method of network-oriented care empowers people with SMI within their own environment. Netherlands Trial Register Identifier: NL6548.

Study protocol for the SeMaCo study: A longitudinal regional cohort study to assess COVID-19 seroprevalence in blood donors

Introduction: Serologic studies are crucial for clarifying the regional dynamics of the SARS-CoV-2 coronavirus pandemic as well as the success of a vaccination campaign against COVID-19. We describe a cohort study investigating the seroprevalence of antibodies against SARS-CoV-2 in Magdeburg (Saxony-Anhalt, Germany). Protocol and study design: The SeMaCo study (Serologische Untersuchungen bei Blutspendern des Großraums Magdeburg auf Antikörper gegen SARS-CoV-2) is a longitudinal, regional cohort study to assess the seroprevalence of COVID-19 in blood donors from Magdeburg (Capital of Saxony-Anhalt) and surrounding areas. We consider blood donors as a surrogate for the healthy, working-age population of Saxony-Anhalt. The study primarily aims to measure the prevalence and kinetics of IgG antibodies against SARS-CoV-2 in first time and repeat blood donors over a period of 21 months. The study explores four survey periods of three to four months each (January–April 21, July–October 21, February–April 22, July–October 22). At each visit, we will assess the attitude towards vaccination, the antibody response following vaccination, as well as undesired vaccination effects. Furthermore, we will collect data on occupational activities, housing conditions and the frequency of family and other social contacts. Discussion: The SeMaCo study extends the spectrum of seroepidemiological investigations in Germany. A longitudinal observation with repeated testing and serial interviews can provide a more accurate view on the dynamics of COVID-19 prevalence and spread than repeated cross-sectional studies. Based on interim results from similar studies, we expect a seroprevalence of SARS-CoV-2 antibodies below 5% in the first survey period. SeMaCo will influence policy decisions and preventative measures.

Everyday flexibility and functional milestones in anorexia nervosa: survey results from a mixed community sample.

PurposeThis study examined the relationship between self-reported cognitive-behavioral flexibility scores on the Eating Disorder Flexibility Index (EDFLIX) and objective social and occupational functional milestones in participants with a lifetime diagnosis of anorexia nervosa (AN). The Work and Social Adjustment Scale (WSAS) was included to compare objective and subjective measures.Methods114 female adult participants with a current (53.5%) or past (46.5%) full or partial AN syndrome diagnosis completed an online survey which included functional milestone questions, the EDFLIX, WSAS, EDE-Q, and DASS-21.ResultsEveryday flexibility scores were significantly associated with WSAS scores, but not functional milestones for the same domain. Lower flexibility was related to higher WSAS work impairment but was not associated with poor occupational outcomes. Lower flexibility was related to higher WSAS social impairment but was not associated with less frequent social contact with friends. Milestones across work, social and relationship areas were not significantly correlated, suggesting individuals have areas of strength and weakness across functional domains. In contrast, WSAS ratings indicated broad functional impairment.ConclusionResults from the milestones suggest self-reported cognitive-behavioral flexibility is not a strong determinant of everyday function. Results from the subjective WSAS function measure and the more objective functional milestones were not consistent. To obtain a more balanced assessment of everyday functioning in AN, both subjective and objective measures should be considered.Level of evidenceLevel III Case–control analytic study.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40519-021-01300-7.

Prevalence of ARVI, influenza, and COVID-19 pathogens in individuals without symptoms of respiratory infection

Introduction. SARS-CoV-2 can be transmitted by infected people without or with mild symptoms of acute respira-tory infection (ARI). Monitoring based on nucleic acid amplification techniques is used to measure the prevalence of ARI pathogens and to assess the effectiveness of preventive measures.The aim is to measure the prevalence of pathogens causing ARIs of viral etiology, influenza, and COVID-19 among individuals without ARI symptoms throughout age groups, to trace changes in the epidemic situation by weekly monitoring pathogens during the inter-epidemic period and at the beginning of a typical ARI epidemic season, to assess the effectiveness of medical masks for prevention of the above infections.Materials and methods. A total of 14,119 people (including 4,582 children) without ARI symptoms went through examination, including questionnaire surveys, in 26 regions of Russia from August to October 2020. Nasopharyn-geal and oropharyngeal swabs were tested by using AmpliSens ARVI-screen-FL, AmpliSens Influenza virus A/B-FL, and AmpliSens Cov-Bat-FL reagent kits (The Central Research Institute of Epidemiology of Rospotrebnadzor, Moscow).Results. 11.1% of the tested samples showed positive results; the rhinovirus prevailed (7.32%), while SARS-CoV-2 was detected in 1.66%. In autumn, the proportion of SARS-CoV-2 infected cases increased from 0.49% to 4.02% (p 0.001). The SARS-CoV-2 RNA concentration was up to 1010 copies/mL.Conclusions. Differences in the prevalence of SARS-CoV-2 and rhinovirus among the age groups and over time were found and analyzed. Using of medical masks reduced the risk of infection with respiratory viruses and with SARS-CoV-2 by 51% and 34%, respectively. In case of prolonged exposure to a COVID-19 patient, healthy people must use a respirator for more effective protection. The individuals whose work was associated with a high level of social contacts were infected more rarely than other individuals in the same age group (p = 0.001); this fact supports the importance of anti-epidemic measures and commitment to their adherence by people whose profession entails frequent social contacts.

Risk and protective factors for mental disorders beyond genetics: an evidence-based atlas.

Decades of research have revealed numerous risk factors for mental disorders beyond genetics, but their consistency and magnitude remainuncer-tain. We conducted a "meta-umbrella" systematic synthesis of umbrella reviews, which are systematic reviews of meta-analyses of individual studies, by searching international databases from inception to January 1, 2021. We included umbrella reviews on non-purely genetic risk or protective factors for any ICD/DSM mental disorders, applying an established classification of the credibility of the evidence: class I (convincing), class II (highly suggestive), class III (suggestive), class IV (weak). Sensitivity analyses were conducted on prospective studies to test for temporality (reverse causation), TRANSD criteria were applied to test transdiagnosticity of factors, and A Measurement Tool to Assess Systematic Reviews (AMSTAR) was employed to address the quality of meta-analyses. Fourteen eligible umbrella reviews were retrieved, summarizing 390 meta-analyses and 1,180 associations between putative risk or protective factors and mental disorders. We included 176 class I to III evidence associations, relating to 142 risk/protective factors. The most robust risk factors (class I or II, from prospective designs) were 21. For dementia, they included type 2 diabetes mellitus (risk ratio, RR from 1.54 to 2.28), depression (RR from 1.65 to 1.99) and low frequency of social contacts (RR=1.57). For opioid use disorders, the most robust risk factor was tobacco smoking (odds ratio, OR=3.07). For non-organic psychotic disorders, the most robust risk factors were clinical high risk state for psychosis (OR=9.32), cannabis use (OR=3.90), and childhood adversities (OR=2.80). For depressive disorders, they were widowhood (RR=5.59), sexual dysfunction (OR=2.71), three (OR=1.99) or four-five (OR=2.06) metabolic factors, childhood physical (OR=1.98) and sexual (OR=2.42) abuse, job strain (OR=1.77), obesity (OR=1.35), and sleep disturbances (RR=1.92). For autism spectrum disorder, the most robust risk factor was maternal overweight pre/during pregnancy (RR=1.28). For attention-deficit/hyperactivity disorder (ADHD), they were maternal pre-pregnancy obesity (OR=1.63), maternal smoking during pregnancy (OR=1.60), and maternal overweight pre/during pregnancy (OR=1.28). Only one robust protective factor was detected: high physical activity (hazard ratio, HR=0.62) for Alzheimer's disease. In all, 32.9% of the associations were of high quality, 48.9% of medium quality, and 18.2% of low quality. Transdiagnostic class I-III risk/protective factors were mostly involved in the early neurodevelopmental period. The evidence-based atlas of key risk and protective factors identified in this study represents a benchmark for advancing clinical characterization and research, and for expanding early intervention and preventive strategies for mental disorders.

Effects of Community-Based Programs on Integration into the Mental Health and Non-Mental Health Communities.

Aims: The purpose of this study was to verify how integration into the mental health community, a subculture of persons with mental illness, affects the integration into the non-mental health community. Thus, we analyzed the effect of community-based mental health service programs on non-mental health community integration, mediated by mental health community integration. Methods: In total, 190 persons with mental illness (M age = 42.78; SD = 11.3; male, 54.7%; female, 45.3%), living in local communities and using community-based mental health programs, participated in the study. We measured their sociodemographic and clinical variables, the environmental variables of mental health service programs, and the level of integration of the mental health and non-mental health communities. The data collected were analyzed to test the proposed hypotheses using Structural Equation Modeling (SEM). Results: The common significant predictors affecting the two types of community integration were symptoms and resource accessibility: the more accessible the various community resources and the less severe the psychiatric symptoms were, the higher the level of the two types of community integration was. In path analysis, the program’s atmosphere and the participation of people with mental illness (program involvement) significantly predicted the level of integration into the mental health community. This, in turn, had a positive effect on their physical integration, social contact frequency, and psychological integration into the non-mental health community, mediated by the integration of the mental health community. Conclusion: Based on the results, we emphasize the importance of mental health communities and suggest strategies to support the integration of mental health communities.

Examining Rural and Racial Disparities in the Relationship Between Loneliness and Social Technology Use Among Older Adults.

Loneliness, the subjective negative experience derived from a lack of meaningful companionship, is associated with heightened vulnerability to adverse health outcomes among older adults. Social technology affords an opportunity to cultivate social connectedness and mitigate loneliness. However, research examining potential inequalities in loneliness is limited. This study investigates racial and rural-urban differences in the relationship between social technology use and loneliness in adults aged 50 and older using data from the 2016 wave of the Health and Retirement Study (N = 4,315). Social technology use was operationalized as the self-reported frequency of communication through Skype, Facebook, or other social media with family and friends. Loneliness was assessed using the UCLA Loneliness scale, and rural-urban differences were based on Beale rural-urban continuum codes. Examinations of race focused on differences between Black/African-American and White/Caucasian groups. A path model analysis was performed to assess whether race and rurality moderated the relationship between social technology use and loneliness, adjusting for living arrangements, age, general computer usage. Social engagement and frequency of social contact with family and friends were included as mediators. The primary study results demonstrated that the association between social technology use and loneliness differed by rurality, but not race. Rural older adults who use social technology less frequently experience greater loneliness than urban older adults. This relationship between social technology and loneliness was mediated by social engagement and frequency of social contact. Furthermore, racial and rural-urban differences in social technology use demonstrated that social technology use is less prevalent among rural older adults than urban and suburban-dwelling older adults; no such racial differences were observed. However, Black older adults report greater levels of perceived social negativity in their relationships compared to White older adults. Interventions seeking to address loneliness using social technology should consider rural and racial disparities.

A Bayesian approach to reveal the key role of mask wearing in modulating projected interpersonal distance during the first COVID-19 outbreak.

Humans typically create and maintain social bonds through interactions that occur at close social distances. The interpersonal distance of at least 1 m recommended as a relevant measure for COVID-19 contagion containment requires a significant change in everyday behavior. In a web-based experimental study conducted during the first pandemic wave (mid-April 2020), we asked 242 participants to regulate their preferred distance towards confederates who did or did not wear protective masks and gloves and whose COVID-19 test results were positive, negative, or unknown. Information concerning dispositional factors (perceived vulnerability to disease, moral attitudes, and prosocial tendencies) and situational factors (perceived severity of the situation in the country, frequency of physical and virtual social contacts, and attitudes toward quarantine) that may modulate compliance with safety prescriptions was also acquired. A Bayesian analysis approach was adopted. Individual differences did not modulate interpersonal distance. We found strong evidence in favor of a reduction of interpersonal distance towards individuals wearing protective equipment and who tested negative to COVID-19. Importantly, shorter interpersonal distances were maintained towards confederates wearing protective gear, even when their COVID-19 test result was unknown or positive. This protective equipment-related regulation of interpersonal distance may reflect an underestimation of perceived vulnerability to infection; this perception must be discouraged when pursuing individual and collective health-safety measures.
