Moving to serene nature may prevent poor mental health—results from a swedish longitudinal cohort study

Green spaces are recognized for improving mental health, but what particular kind of nature is required is yet not elucidated. This study explores the effect of specific types of recreational nature qualities on mental health. Longitudinal data (1999/2000 and 2005) from a public health survey was distributed to a stratified sample (n = 24,945) of a Swedish population. People from rural or suburban areas (n = 9230) who had moved between baseline and follow-up (n = 1419) were studied. Individual geographic residence codes were linked to five predefined nature qualities, classified in geographic information systems (GIS). Any change in the amount of or type of qualities within 300 m distance between baseline and follow-up was correlated to any change in mental health (as measured by the General Health Questionnaire) by logistic regression models. On average, the population had limited access to nature qualities both pre- and post-move. There was no significant correlation between change in the amount of qualities and change in mental health. However, the specific quality “serene” was a significant determinant with a significantly decreased risk for women of change to mental ill-health at follow-up. The objective definition of the potentially health-promoting quality may facilitate implication in landscape practice and healthy plannin

The association between active participation in a sports club, physical activity and social network on the development of lung cancer in smokers: a case-control study

<p>Abstract</p> <p>Background</p> <p>This study analyses the effect of active participation in a sports club, physical activity and social networks on the development of lung cancer in patients who smoke. Our hypothesis is that study participants who lack social networks and do not actively participate in a sports club are at a greater risk for lung cancer than those who do.</p> <p>Methods</p> <p>Data for the study were taken from the <b>Co</b>logne <b>Smo</b>king <b>S</b>tudy (<b>CoSmoS</b>), a retrospective case-control study examining potential psychosocial risk factors for the development of lung cancer. Our sample consisted of n = 158 participants who had suffered lung cancer (diagnosis in the patient document) and n = 144 control group participants. Both groups had a history of smoking.</p> <p>Data on social networks were collected by asking participants whether they participated in a sports club and about the number of friends and relatives in their social environment. In addition, sociodemographic data (gender, age, education, marital status, residence and religion), physical activity and data on pack years (the cumulative number of cigarettes smoked by an individual, calculated by multiplying the number of cigarettes smoked per day by the number of years the person has smoked divided by 20) were collected to control for potential confounders. Logistic regression was used for the statistical analysis.</p> <p>Results</p> <p>The results reveal that participants who are physically active are at a lower risk of lung cancer than those who are not (adjusted OR = 0.53*; CI = 0.29-0.97). Older age and lower education seem also to be risk factors for the development of lung cancer. The extent of smoking, furthermore, measured by pack years is statistically significant. Active participation in a sports club, number of friends and relatives had no statistically significant influence on the development of the cancer.</p> <p>Conclusions</p> <p>The results of the study suggest that there is a lower risk for physically active participants to develop lung cancer. In the study sample, physical activity seemed to have a greater protective effect than participation in a sports club or social network of friends and relatives. Further studies have to investigate in more detail physical activity and other club participations.</p

COVID-19 and Precarious Employment: Consequences of the Evolving Crisis

The world of work is facing an ongoing pandemic and an economic downturn with severe effects worldwide. Workers trapped in precarious employment (PE), both formal and informal, are among those most affected by the COVID-19 pandemic. Here we call attention to at least 5 critical ways that the consequences of the crisis among workers in PE will be felt globally: (a) PE will increase, (b) workers in PE will become more precarious, (c) workers in PE will face unemployment without being officially laid off, (d) workers in PE will be exposed to serious stressors and dramatic life changes that may lead to a rise in diseases of despair, and (e) PE might be a factor in deterring the control of or in generating new COVID-19 outbreaks. We conclude that what we really need is a new social contract, where the work of all workers is recognized and protected with adequate job contracts, employment security, and social protection in a new economy, both during and after the COVID-19 crisis

Delimiting the Origin of a B Chromosome by FISH Mapping, Chromosome Painting and DNA Sequence Analysis in Astyanax paranae (Teleostei, Characiformes)

Supernumerary (B) chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH) is a useful tool for ascertaining the origin of these genomic elements, especially when combined with painting from microdissected B chromosomes. In order to investigate the origin of B chromosomes in the fish species Astyanax paranae, these two approaches were used along with PCR amplification of specific DNA sequences obtained from the B chromosomes and its comparison with those residing in the A chromosomes. Remarkably, chromosome painting with the one-arm metacentric B chromosome probe showed hybridization signals on entire B chromosome, while FISH mapping revealed the presence of H1 histone and 18S rDNA genes symmetrically placed in both arms of the B chromosome. These results support the hypothesis that the B chromosome of A. paranae is an isochromosome. Additionally, the chromosome pairs Nos. 2 or 23 are considered the possible B chromosome ancestors since both contain syntenic H1 and 18S rRNA sequences. The analysis of DNA sequence fragments of the histone and rRNA genes obtained from the microdissected B chromosomes showed high similarity with those obtained from 0B individuals, which supports the intraspecific origin of B chromosomes in A. paranae. Finally, the population hereby analysed showed a female-biased B chromosome presence suggesting that B chromosomes in this species could influence sex determinism.This research was funded by grants from the State of São Paulo Research Foundation (FAPESP) to DMZAS (2011/16825-3) and CO (2010/17009-2), grants from National Council for Research and Development (CNPq) to FF and by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

Biodiversity and health in the urban environment

Biodiversity underpins urban ecosystem functions that are essential for human health and well-being. Understanding how biodiversity relates to human health is a developing frontier for science, policy and practice. This article describes the beneficial, as well as harmful, aspects of biodiversity to human health in urban environments. Recent research shows that contact with biodiversity of natural environments within towns and cities can be both positive and negative to human physical, mental and social health and well-being. For example, while viruses or pollen can be seriously harmful to human health, biodiverse ecosystems can promote positive health and well-being. On balance, these influences are positive. As biodiversity is declining at an unprecedented rate, research suggests that its loss could threaten the quality of life of all humans. A key research gap is to understand-and evidence-the specific causal pathways through which biodiversity affects human health. A mechanistic understanding of pathways linking biodiversity to human health can facilitate the application of nature-based solutions in public health and influence policy. Research integration as well as cross-sector urban policy and planning development should harness opportunities to better identify linkages between biodiversity, climate and human health. Given its importance for human health, urban biodiversity conservation should be considered as public health investment

Different social network and social support characteristics, nervous problems and insomnia: Theoretical and methodological aspects on some results from the population study 'men born in 1914', Malmö, Sweden

A representative sample of 68-year-old men in the Swedish city of Malmö, were interviewed in detail regarding their social network, social support and social influence as a part of an extensive examination of their health status. Emphasis in this paper is put on the definition and operationalization of different social network, social support and social influence characteristics included in a tentative model. The reliability and validity of the different social network, social support and social influence indices are analyzed and discussed. The relation between the different indices and marital status and social class are analyzed implying that men living alone and men in the lowest social class have the most insufficient social network, social support and social influence. The indices were then used in an analysis of nervous problems and insomnia. Social anchorage, social participation and contact frequency, all subconcepts of social network, had independent associations with mental health in this cross-sectional study. The addition of the social network, social support and social influence indices to social class and marital status gives a more differentiated and thereby a more valid picture of the association between the psychosocial environment and this type of mental health problems.social network social support social class marital status epidemiology mental health problems

Sexual harassment, other types of harassment and derogatory treatment in the academy

BACKGROUND: Sexual harassment (SH) continues to be a significant public health problem, especially among women. SH and other types of harassment and derogatory treatment/bullying exist at many academic workplaces. The aim of this study is to explore how SH relates to other forms of harassment among staff at a large Swedish university, separated by gender. METHODS: Using data from a web-based survey sent out to all staff in November 2019 (response rate 33%), a multiple logistic regression analysis was performed. Exposure to SH was defined as having experienced at least one of ten defined SH behaviours related to work. Exposure to harassment (other than sexual) was defined as having experienced violation of onés dignity associated with one of the Swedish seven legal grounds for discrimination: sex, transgender identity or expression, ethnicity, religion or other belief, disability, sexual orientation or age. Exposure to derogatory treatment was defined as having experienced undesirable negative behaviours, such as withholding information, derogatory comments or exclusion. All SH, harassment and derogatory treatment took place during the last 12 months. RESULTS: Preliminary results show a sixfold increased risk among women subjected to SH to also experience harassment, a three times higher risk to experience derogatory treatment and a seven times higher risk to experience multiple forms of harassment (two or more forms of harassment or derogatory treatment) compared to women unexposed to SH. The elevated risk remained after adjusting for relevant background variables. The pattern was similar among men but with lower prevalence of SH, harassment and derogatory treatment. CONCLUSIONS: The results indicate that individuals subjected to SH at work have an increased risk of experiencing other types of harassment or derogatory treatment. This new information is relevant to consider in prevention of SH and harassment in academia. KEY MESSAGES: • The results indicate that individuals subjected to sexual harassment at work have an increased risk of experiencing other types of harassment or derogatory treatment. • Findings indicating a relationship between sexual harassment and other types of harassment or derogatory treatment may be valuable for counteracting the problem

Social network, social support and acute chest complaints among young and middle-aged patients in an emergency department--A case-control study

The risk of developing non-specific chest complaints was higher among young and middle-aged persons with a weak social network and low social support, when comparing cases with controls at a hospital emergency department (ED). The study was comprised of 62 cases; two different control groups were recruited from other patients at the medical ED (n = 67) and from patients at the surgical ED with urolithiasis or cholecystitis (n = 31). Relative risks for non-specific chest complaints were 2.3-3.4 for patients with a low score on two of the social network factors (an overall index and social anchorage) and two social support factors (emotional esteem support and support by a confidant). These results could be used for developing guidelines for a more adequate clinical management of these patients, as well as for the prevention of stress-related conditions in general. An analysis was made of the conceptual validity of the instrument used for assessing social network and social support. It was concluded that structural elements, such as social network factors, represented a more valid measurement that was less affected by subjectivity. Future research is of importance for finding overbridging concepts, rather than to further continue the dissection of presently used indices into even more 'specific' variables.psychosocial factors social support social network emergency department chest complaints care utilization

Testing two methods to create comparable scale scores between the Job Content Questionnaire (JCQ) and JCQ-like questionnaires in the European JACE study

Background: Scale comparative properties of "JCQ-Iike" questionnaires with respect to the JCQ have been little known. Purpose: Assessing validity and reliability of two methods for generating comparable scale scores between the Job Content Questionnaire (JCQ) and JCQ-like questionnaires in sub-populations of the large Job Stress, Absenteeism and Coronary Heart Disease European Cooperative (JACE) study: the Swedish version of Demand-Control Questionnaire (DCQ) and a transformed Multinational Monitoring of Trends and Determinants in Cardiovascular Disease Project (MONICA) questionnaire. Method: A random population sample of all Malmo males and females aged 52-58 (n = 682) years was given a new test questionnaire with both instruments (the JCQ and the DCQ). Comparability-facilitating algorithms were created (Method I). For the transformed Milan MONICA questionnaire, a simple weighting system was used (Method II). Results: The converted scale scores from the JCQ-Iike questionnaires were found to be reliable and highly correlated to those of the original JCQ. However, agreements for the high job strain group between the JCQ and the DCQ, and between the JCQ and the DCQ (Method I applied) were only moderate (Kappa). Use of a multiple level job strain scale generated higher levels of job strain agreement, as did a new job strain definition that excludes the intermediate levels of the job strain distribution. Conclusion: The two methods were valid and generally reliable
