Aim: The purpose of this study was to investigate associations between workplace violence and sleep disturbances in the Swedish working population, and to estimate potential dose-response relationships. Methods: Data were derived from two waves (2014 and 2016) of the Swedish Longitudinal Occupational Survey of Health (n=9364). Sleep disturbances were measured with four items of the Karolinska Sleep Questionnaire and one question asked whether the participants were exposed to violence or threats of at the workplace in the past six months. Multiple logistic regression analyses were performed. Results: Exposure to workplace violence was associated with higher odds of concurrent sleep disturbances (cross-sectional approach). Workplace violence was also associated with higher odds of subsequent sleep disturbances, but only when covariates were not adjusted for (prospective approach). Sleep disturbances were associated with higher odds of subsequent workplace violence (reverse approach). A dose-response relationship was found in the cross-sectional approach but not in the prospective and reverse approach. Conclusion: The findings suggested that there was a cross-sectional association between workplace violence and sleep disturbances, and that sleep disturbances were prospectively associated with exposure to workplace violence, but the results did not support a statistically significant prospective association between workplace violence and sleep disturbances.

The purpose of the study was to examine the relationship between sleep patterns, motor proficiency and commonly co-occurring neurodevelopmental disorders in children, attitude to physical activity, mental health, and age. The study also looked at differences in sleep efficiency, as well as, perceived adequacy in physical activity between typically developing children and children with low motor proficiency. The sample consisted of 127 participants, 6-12 years old living in Perth, Western Australia. 51% participants were considered typically developing and 49% to have low motor proficiency. Motor proficiency, indications of Attention-Deficit/Hyperactivity Disorder, Autism Spectrum Disorder and anxiety/depression, adequacy in, or predilection for physical activity did not show a relationship to sleep efficiency. Significant differences between groups in sleep efficiency or adequacy in physical activity were not found. No interaction effect of neurodevelopmental disorders were identified. Sleep in children with movement impairments caused by neurodevelopmental disorders is an area where continued studies are of great importance. Although no relationship was identified in the current study, previous research has suggested sleep may play an important role for development and optimal everyday functioning. A better understanding of physical and psychological consequences and possible contributing factors of low motor proficiency in childhood is important as the risk of long-term dysfunction in emotional, cognitive and physical areas may be reduced in an optimal environment.

Introduction : L’Odontologie est considérée comme une profession stressante, fréquemment associée à des problèmes de santé, tant d’ordre physique que psychique. L’objectif de cette étude est d’élucider le rôle de certains facteurs psychosociaux chez les Chirurgiens Dentistes Français et Brésiliens.Méthode : Nous avons mené une étude longitudinale auprès de 322 Chirurgiens-Dentistes (161 Français et 161 Brésiliens) au premier temps et au deuxième temps sur une cohorte de 179 (94 Français et 85 Brésiliens). Des mesures relatives à certaines caractéristiques socio-démographiques, psychosociales et transactionnelles ont été ont été administrées aux Chirurgiens-Dentistes. Les critères retenus étaient le burnout, la dépression, les troubles musculo-squelettiques et les troubles du sommeil évaluées à T2 ainsi que des stratégies de coping. Nous avons construit une échelle de stress spécifique à notre population. L’analyse factorielle a permis d’obtenir 1 facteur. Dans une perspective prédictive, des analyses en équation structurales nous ont permis, pour chacun le burnout et la dépression, de tester l’adéquation d’un modèle théorique aux données observées.Résultats : L’influence des scores obtenus sur le burnout, les troubles musculo-squelettiques et les troubles du sommeil) est confirmée par des analyses typologiques identifiant trois profils des dentistes : les dentistes en bonne santé, moins accomplis et en mauvaise santé. Les profils des dentistes Français et Brésiliens sont similaires. Les profils des dentistes moins accomplis et en mauvaise santé liés à certains facteurs psychosociaux, semblent particulièrement à risque de développer une mauvaise santé. Nous avons mis en évidence plusieurs modèles intégratifs témoignant d’effets directs et indirects des antécédents sur les critères, médiatisés par certaines variables transactionnelles. Les variables ratio effort/récompense et le coping de réévaluation du problème ont des effets médiateurs sur : le perfectionnisme et l’épuisement émotionnel, la solitude et l’épuisement émotionnel, le sentiment de solitude et la dépression. Le perfectionnisme prédit la dépression, cet effet passe par le ratio effort/récompense. Conclusion : Ces résultats montrent l’intérêt d’appliquer le modèle transactionnel à la santé des Chirurgiens-Dentistes et suggèrent des pistes de réflexion concernant les perspectives appliquées que ce soit en terme de prévention ou de prise en charge. / Introduction: The Dentistry is considered a stressful profession, being frequently associated with health problems, physical as much mental. The objective of this study is to elucidate the role of psychosomatic factors that affect French and Brazilian dentists.Method: Was made a longitudinal study in 322 dentists (161 French and 161 Brazilians), at a first turn, and 179 dentists at a second turn (when 94 was French and 85 was Brazilians). Measures related to certain socio demographic characteristics (psychosomatic and transactional) were administered for the dentists. The study’s criterions at the second turn were: burnout, depression, muscle-skeleton’s disturbances and sleep disturbances and copping strategies. We construct a specific stress scale for our sample. The factorial analysis resulted in only one factor. Through a perspective predictive, analysis of structural equations allowed to burnout and to depression to test a theoretical model across the observed data.Results: The score analysis obtained from burnout, depression, muscle-skeleton’s disturbances and sleep disturbance, allowed to identify, by cluster analysis, three dentists’ profiles: “with good health”; “with minor personal accomplishment”; “with health at risk”. The French and Brazilian dentist profiles were similar. The psychosomatic factors that influence the adhesion to a one of these profiles are different between the two groups (French and Brazilians). At France, above all, are the context variables and from stress processes (imbalance of effort and reward, specific stress of dentists and copping strategies) that are risk factors to the health. At Brazil, this is the dispositional variables (age, perfectionism and over commitment). We tested an integrator model which showed direct and indirect effects on criterions of our study, mediated by some transactional variables. The variables imbalance between effort and reward and copping, in the revaluation of the problem, has mediation’s effects between perfectionism and emotional exhaustion, between the solitude and emotional exhaustion, between the solitude and depression and between perfectionism and depression.Conclusions: These results showed the interest of application of the transactional model to the health of the surgeons dentists in two different cultures and suggests ways to a reflection about the applied perspectives, in terms of prevention as much as care. / Introdução - A Odontologia é considerada uma profissão estressante, frequentemente associada a problemas de saúde tanto física quanto mental. O objetivo deste estudo é elucidar o papel dos fatores psicossociais em Cirurgiões-Dentistas franceses e brasileiros. Método - Realizou-se um estudo de corte longitudinal em dois tempos. No primeiro tempo com 322 dentistas, sendo 161 franceses e 161 brasileiros, e no segundo tempo com 94 franceses e 85 brasileiros, totalizando 179 dentistas. Medidas relacionadas a determinadas características sociodemográficas, psicossociais e transacionais foram administradas nos dentistas. Os critérios do estudo foram: burnout, depressão, distúrbios músculo-esqueléticos e do sono em T2 e estratégias de coping. Construiu-se uma escala de estresse específico para essa população, e a análise fatorial resultou em um fator. Por meio de uma perspectiva preditiva as análises de equações estruturais permitiram, tanto para o burnout quanto para a depressão, testar um modelo teórico a partir dos dados observados.Resultados - A análise dos escores obtidos do burnout e dos distúrbios músculo-esquelético e do sono permitiu identificar, pelas análises de cluster, três perfis de dentistas: com boa saúde, com menor realização pessoal e com saúde precária. Os perfis dos dentistas franceses e brasileiros são semelhantes, mas os fatores psicossociais que influenciam a adesão a um desses perfis são diferentes entre os dois países. Na França são, sobretudo, as variáveis de contexto e do processo de estresse: desequilíbrio esforço/ recompensa, estresse específico dos dentistas e estratégias de coping, que são fatores de risco para a saúde. No Brasil são as variáveis disposicionais, como idade, perfeccionismo e supercomprometimento. Testou-se um modelo integrador que mostra efeitos diretos e indiretos sobre os critérios deste estudo, mediados por certas variáveis transacionais. As variáveis desequilíbrio e esforço-recompensa e coping reavaliação do problema têm efeitos de mediação entre: perfeccionismo e exaustão emocional; solidão e exaustão emocional; solidão e depressão; e perfeccionismo e depressão. Conclusão – Os resultados mostram o interesse da aplicação do modelo transacional à saúde dos Cirurgiões-Dentistas em duas culturas diferentes, e sugerem caminhos para a reflexão em relação às perspectivas aplicadas tanto em termos de prevenção quanto de cuidados.

Introduction: adequate sleep is essential to maintain a healthy life. Inadequate sleep causes various health impacts. The Centers for disease control and prevention (CDCP) from the USA announced in 2015 that sleep disorders and insufficient sleep are global health epidemics. Globally, immigration has risen especially in Sweden compared to past decades. Immigration is one of the factors of social determinants of health. Since immigration show an increasing trend, it is necessary to give much attention to the sleep health of immigrants in a health science context. Aim: The main purpose of this study is to explore the prevalence and factors associated with sleep disturbances among immigrants in Sweden. Method: Cross-sectional survey study conducted by distributing self-administered questionnaires online. Results: the prevalence of sleep disturbance among immigrants in Sweden was 69.16% (n=83). The most common self-identified factors associated with sleep disturbance were stress (62.4%, n=73) as psychological factors and high room temperature (48.3%, n=58) as environmental factors Conclusion: These findings show the necessity of taking immediate action to prevent further sleep consequences and climate change effects because of the increasing immigration trend. Future research studies can focus more on interventions that could control the impact of climate change-related sleep disturbances.
