Workers may be exposed to conditions that put their physical and mental integrity at risk, from workplace settings to climate characteristics. Heat stress is a harmful health condition caused by exceeding the human body's tolerance limits, leading to illness and increasing the chance of work accidents. Heat stress indexes, such as the Humidex and the Heat Index (HI), are used to measure these impacts. These indexes are significant as they provide a quantitative measure of the heat stress experienced by workers, taking into account both environmental and individual factors.

Objective: This study aims to compare multiple heat stress indexes, relating them to historical Brazilian occupational accident data.

Methods: We selected eight indexes and applied multiple correspondence analysis to each one, a statistical method that generates graphs to visualize the association between variables in a database.

Results: The analysis and comparison of the graphs indicated that seven of the eight indexes presented similar behavior. It was also possible to relate ranges of index values with specific characteristics of the accidents.

Conclusions: The technique allowed us to analyze the relationship between climate and work accidents and showed that the choice of the heat stress index does not significantly alter the results for most indexes studied.

Objective: Early childhood exposure to violent media content represents an actionable target for preventive intervention. The associated risks for later aggressive behavior have been established in childhood, but few studies have explored widespread long-term associations with antisocial behavior. We investigate prospective associations between exposure to violent television content in early childhood and subsequent antisocial behavior in mid-adolescence.

Method: Participants are 963 girls and 982 boys from the Quebec Longitudinal Study of Child Development (QLSCD) birth cohort. Parents reported the frequency of their child's exposure to violent television content at ages 3.5 and 4.5 years. Four indicators of antisocial behavior were self-reported by participants at age 15 years. These indicators were linearly regressed on exposure to violent television content at ages 3.5 and 4.5 years. All analyses, stratified by sex, controlled for pre-existing and concurrent potential individual and family confounding variables.

Results: For boys, preschool violent televiewing was associated with increases in proactive aggression (β = 0.065; 95% CI, 0.001 to 0.089), physical aggression (β = 0.074; 95% CI, 0.040 to 0.487), and antisocial behavior (β = 0.076; 95% CI, 0.013 to 0.140) by mid-adolescence. No prospective associations were found for girls.

Conclusions: This study of typically developing children demonstrates long-term perils associated with early exposure to violent content in childhood. We observed risks for aggressive and delinquent behavior in boys, more than a decade later. Preventive intervention campaigns that target knowledge transfer to parents and communities regarding the potential insidious consequences of preschool exposure promise more optimal development in youth.

Tooth loss among indigenous people in the Amazon emphasizes the need for culturally appropriate oral health interventions. The objective of this study was to analyze the incidence of tooth loss in two remote Amazon indigenous populations. This prospective cohort evaluated a total of 47 indigenous in the permanent dentition at T0 and thirteen years later (T1) from two villages, Arara-Laranjal (n = 28, mean age 16.1 and 29.9 years) and Assurini do Xingu (n = 19, mean age 15.9 and 29.5 years), of different ethnic groups. A multilevel Poisson regression model assessed the influence of village, sex, and age on tooth loss. At T0, the indigenous people had all their permanent teeth. Forty-two lost at least one tooth (89%), and a total of 172 teeth were lost at T1 at an incidence of 97% among females and 76% in males. There was no influence of ethnicity on tooth loss (p = 1.000). A lower risk of tooth loss was associated with male subjects (β = -0.50, p < 0.05) but not with age. In females (22/46.8%) and males (11/23.4%), the highest incidence of tooth loss was the lower second molars. The risk was higher among females, and there was no influence on age, village, or ethnicity. The second and first molars were the most affected teeth. These findings suggest an increase in tooth loss caused by close contact between indigenous and urban populations.

Social media use has rapidly increased over the past decade, especially among young people. To obtain more insight into the potential negative associations with problematic social media use in Dutch early adolescents, we assessed its relation to self-reported well-being. We conducted a cross-sectional study with 585 students in their final year of primary school (11-12 years old) who completed a questionnaire during school hours. We examined the association between problematic social media use and psychosomatic complaints, as well as general life satisfaction and whether perceived social support and sex moderated these associations. Problematic social media use was associated with lower general life satisfaction, as well as all psychosomatic complaints, with the strongest association for having a bad mood or feeling irritated (OR = 3.08, 99% CI = 2.05-4.63). Most associations were not moderated by perceived social support or sex. Our findings indicate that the well-being of early adolescents may be affected by problematic social media use already in primary school. The association persisted regardless of the amount of perceived social support, and without strong gender differences. This suggests that the potential for limiting the potential negative consequences of problematic social media use through increasing social support is limited.

Background: Absenteeism among healthcare workers (HCWs) disrupts workflows and hampers the delivery of adequate patient care. The aim of the study was to examine predictors of sick leaves among HCWs in a tertiary medical center in Lebanon.

Methods: A retrospective analysis of sick leaves linked to health records of 2850 HCWs between 2015 and 2018 was performed. Sick leave episodes were stratified by diagnosis. Bivariate and negative binomial regression analyses were performed to investigate predictors.

Results: The mean number of sick leave episodes was 10.6 per person over 4 years. The strongest predictor of higher sickness absenteeism was low job grade (IR = 1.52; 95% CI = 1.39, 1.67). Female sex (IR = 1.24; 95% CI = 1.14, 1.36), older age (IR = 1.19; 95% CI = 1.08, 1.30), being married (IR = 1.21; 95% CI = 1.11, 1.33), being a current smoker (IR = 1.21; 95% CI = 1.11, 1.32), and having a history of selected medical conditions were all significant sick leave predictors.

Conclusion: Demographic, work-related, and health-related predictors are associated with the number of sick leave episodes. To address the health inequity, additional research should evaluate how some socio-economic factors determine poorer health outcomes and should guide approaches to address this crucial issue to protect the health and well-being of this key workforce.

Introduction: Rural areas face additional challenges in preventing, preparing for, responding to, and recovering from disasters. This study aimed to understand how rural primary healthcare professionals (PHCPs) perceive their roles, involvement, and capacity in disaster health management.

Methods: For this qualitative descriptive research, semi-structured interviews were carried out with convenience and purposive samples of rural PHCPs before and during the COVID-19 pandemic. Open, axial, and selective coding were employed to analyse the data inductively.

Results: Five interviews were conducted before the pandemic, and ten interviews were conducted during the second and third waves of the COVID-19 pandemic in Australia. The themes identified were similar between the two periods. Rural PHCPs were underutilised due to a lack of awareness of their capacity and a lack of infrastructure and support for greater involvement.

Conclusions: Rural PHCPs can be better integrated and supported in readiness for a whole-system response to future disasters. This study recommends empowering PHCPs in disaster management to promote the health and continuity of care in rural communities.

There is an increasing global acknowledgment of the critical role that men have as key partners in maternal, newborn, and child health (MNCH). Most male-engagement initiatives do not address the perceived benefits and risks that women may experience because of increased male participation in MNCH, especially in Kenya. The aim of this study, therefore, is to qualitatively assess how women perceive and experience increased male engagement in MNCH in western Kenya. Using a phenomenological approach, 53 women (35 mothers and 18 mothers-in-law) were purposively selected from seven communities in Kakamega County and participated in seven focus group discussions (FGD) in November and December 2020. Our findings suggest that the level of support for increased male involvement in MNCH varies depending on the type of participant. While mothers-in-law were less supportive of increased male involvement, mothers were more supportive of male involvement that fosters gender equity, such as joint decision making. Most mothers-in-law argued that women are 'naturally' closer to children, that men cannot care for children and their involvement may harm children, and men's involvement may give men more control over women's spaces. These findings show that programmatic initiatives to enhance male engagement in MNCH must consider mothers-in-law's concerns and leverage mothers' desire to engage men in a gender-equitable way.

The COVID-19 pandemic significantly impacted the lives of families worldwide. Findings suggest a substantial impact of the COVID-19 pandemic on maternal mental health. Yet, much less is known about the impact of COVID-19 on paternal mental health. This study describes depression and anxiety and risk and protective factors among fathers of young children largely residing in Canada during the COVID-19 pandemic. Fathers (N = 70) of children 0 to 8 years old self-reported depression (EPDS, CESD, CESD-R) and anxiety (PASS, GAD-7) symptoms, while mothers (N = 236) provided reports of paternal depressive symptoms using the EPDS-P. Fathers evidenced clinically significant depression (37.1%) and anxiety (22.9%). Linear regression models with significant bivariate correlates indicated that depressive symptoms were associated with a mental health history and experiencing recent stressful events in the past month, while anxiety symptoms were related to mental health history over and above other correlates. Mother-reported paternal depression was prevalent (61.9%) and associated with lower mother-reported marital quality and higher maternal depressive symptoms. Of the fathers reporting clinically significant mental health concerns, less than one-third reported accessing mental health services. Paternal depression and anxiety symptoms were elevated during the pandemic, when compared to pre-pandemic comparisons. The risk and protective factors for paternal depression and anxiety included mental health history, recent stressful events, maternal marital quality, and maternal depressive symptoms. Longitudinal studies evaluating the persistent impact of the COVID-19 pandemic on paternal mental health are needed to inform continued efforts to repair the pandemic's impact on family wellbeing.

Food insecurity (FI) is associated with several known hepatocellular carcinoma (HCC) risk factors, but few studies have directly examined FI in association with HCC risk. We aimed to investigate whether county-level FI is associated with HCC risk. We used data from 21 registries in the Surveillance Epidemiology and End Results database to obtain county-level counts of HCC cases from 2018 to 2021. We obtained the county-level FI rates for 2018-2021 from Feeding America's Map the Meal Gap. We used multi-level Poisson regression models with robust standard errors to calculate incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Overall, a one-standard-deviation (SD) increase in county-level FI was associated with an 8% increase in HCC risk in the fully adjusted model (IRR = 1.08, 95% CI = 1.06, 1.10). When stratified by age at diagnosis, a one-SD increase in county-level FI was associated with a 2% higher risk of HCC in the ≥65 age group (IRR = 1.02, 95% CI = 1.00, 1.05) and a 15% higher risk in the <65 age group (IRR = 1.15, 95% CI = 1.11, 1.19; interaction p-value < 0.001). If confirmed in other studies, these findings support the need for interventions and policies addressing FI in populations at increased risk for HCC.

Out-of-home meals are characterized by poor nutritional quality, and their intake has been linked to adverse health outcomes. Therefore, national and local government initiatives have been implemented in the UK to promote healthier out-of-home meals. However, there is limited evidence of their effectiveness. This study evaluated the fat content and fatty acid profile of takeaway meals from 'standard' and from Healthier Catering Commitment (HCC)-approved takeaway outlets. Meals from 14 'standard' and 13 'HCC-awarded' takeaways (74 meals and 26 side dishes) were analyzed for total fat and fatty acid composition. No statistically significant differences in total fat, saturated, and trans fatty acids per 100 g and per portion between HCC and standard meals were observed, except for donner kebabs. Over 70% of all meals contained more than the recommended 30% of daily fat intake from a single meal. Some meals could provide more than 50% of the recommended total fat and SFAs intake. Despite businesses participating in the healthier out-of-home meal initiative, there has not been a significant improvement in the nutritional quality of the meals they offer. Further research to develop effective approaches to support independent takeaway businesses in offering meals with improved nutritional quality is warranted.
