Associations Between Lifestyle Factors, Oral Health Behaviors, and Glycemic Control in Type 2 Diabetic Patients

Introduction: T2DM mellitus (T2DM) is a major global health issue associated with significant morbidity, mortality, and economic burden. While the role of lifestyle factors in glycemic control is well-established, the influence of oral health behaviors remains underexplored. Objective: This study aimed to investigate the interplay between lifestyle habits, oral health behaviors, and glycemic control in patients with T2DM. Methodology: A cross-sectional study was conducted on 132 patients (66 men and 66 women) with T2DM at the Pius Brînzeu Emergency Hospital in Timișoara, Romania. Data on smoking, physical activity, alcohol consumption, tooth brushing frequency, and dental visits were collected using structured questionnaires, and glycemic control was assessed through HbA1c measurements. Statistical analyses, including Pearson correlations and linear regression, were performed. Results: Among men, HbA1c levels were negatively associated with exercise frequency (ß = −0.26, p < 0.05) and education level (correlation coefficient −0.27, p < 0.05), and positively associated with dental visits and tooth brushing frequency (correlation coefficient 0.26, p < 0.05). In the combined analysis, education level positively correlated with both dental visits (correlation coefficient 0.24, p < 0.01) and alcohol consumption (correlation coefficient 0.22, p < 0.05). Conclusions: These findings underscore the importance of integrating oral health and lifestyle interventions into diabetes management to optimize patient outcomes.

The Role of Sarcopenic Obesity in Hyperlipidemia and Its Impact on Metabolic Health

Sarcopenic obesity, a condition characterized by the simultaneous presence of reduced muscle mass and increased adiposity, has emerged as a critical health concern in the context of metabolic disorders. This review examines the complex interplay between sarcopenic obesity and hyperlipidemia, focusing on the implications for metabolic health. The coexistence of diminished muscle mass and excess fat alters lipid metabolism, leading to elevated circulating lipid levels and exacerbating cardiovascular risks. Mechanisms contributing to this dysregulation include insulin resistance, chronic low-grade inflammation, and altered adipokine secretion, all of which are exacerbated in sarcopenic obesity. Moreover, the condition predisposes individuals to metabolic syndrome, type 2 diabetes, and cardiovascular diseases, highlighting the need for targeted therapeutic strategies. This article discusses the underlying pathophysiology, the role of lifestyle factors, and potential interventions aimed at mitigating the impact of sarcopenic obesity on hyperlipidemia and overall metabolic health. Keywords: Sarcopenic obesity, hyperlipidemia, metabolic health, insulin resistance, inflammation, adipokines, cardiovascular disease, metabolic syndrome

The Role of Lifestyle Factors, Psychological Stress and Interventions in Type 2 Diabetes Mellitus: A Comprehensive Review, Challenges and Future Direction

Type 2 diabetes mellitus (T2DM) is a multifaceted chronic condition characterized by insulin resistance and hyperglycemia. This review synthesizes evidence on the influence of lifestyle factors such as diet, physical activity, and stress on the development and progression of T2DM. It highlights the intricate relationship between obesity, insulin resistance, and β-cell dysfunction, with a particular focus on the role of psychological stress in exacerbating disease outcomes. Through the analysis of recent studies, the review explores how lifestyle interventions, including dietary changes, exercise, and stress management, can improve glycemic control and reduce complications. This comprehensive review underscores the need for integrated, personalized management strategies in T2DM care, emphasizing the importance of addressing both physiological and psychological factors to optimize outcomes and prevent complications.

Well-Being and Cardiovascular Health: Insights From the UK Biobank Study.

Cardiovascular diseases (CVDs) are a leading global health concern. Emerging evidence suggests a potential protective role of well-being in reducing CVD risk. We conducted a cohort analysis using the UK Biobank data set, encompassing 121 317 participants. We assessed the well-being of participants using a well-being index derived from baseline questionnaires. Well-being categories were derived by latent class analysis using general happiness and satisfaction with family, friendships, health, and finance situations. The relationship between well-being and 4 major CVDs was analyzed using Cox proportional hazards models and Mendelian randomization. The study also examined the impacts of well-being on lifestyle factors and inflammatory markers, and its mediating role in the well-being-CVD relationship. Higher well-being was associated with a significantly reduced risk of various CVDs. Latent class analysis identified 4 distinct well-being groups (low, variable, moderate-to-high, and high satisfaction), with higher satisfaction levels generally associated with lower risk of CVDs. Mendelian randomization suggested potential causal relationships between well-being and reduced risk of CVDs. Participants with greater well-being demonstrated healthier behaviors and lower levels of inflammatory markers. Mediation analysis indicated that lifestyle and inflammatory markers partially mediated the relationship between well-being and CVDs. This study demonstrates a robust inverse association between well-being and the risks of CVDs, suggesting that enhancing well-being may be a viable strategy for CVD prevention. The role of lifestyle factors and inflammation as a mediator provides insight into possible biological pathways linking psychological states and cardiovascular health.

Health Professionals' Perceptions about Prostate Cancer-A Focus Group Study.

Prostate cancer (PCa) accounts for 20% of new cancer cases and 10.5% of cancer-associated mortality in Portugal. Associated risk factors include advanced age, family history, genetic alterations, and race/ethnicity. However, the role of lifestyle factors is often underestimated. To explore health professionals' perceptions of PCa risk factors, a qualitative study with three focus groups (FG), with a total of twenty-one general practitioners and urologists, was conducted via videoconference between February and April 2023. Seven themes emerged, including general perceptions of PCa; PCa risk factors; nutritional impact; the role of physical activity; alcohol consumption and smoking; sexual activity and sexually transmitted diseases roles in PCa; and screening, diagnosis, and treatment methods. Despite agreeing that healthy lifestyles could promote better PCa outcomes and quality of life, participants did not specify any lifestyle factors that could promote or prevent this disease, posing challenges to lifestyle changes, particularly among older adults. Non-invasive screening methods, such as biomarkers and alternative treatments, are crucial for future research. This study underscores the need for further investigation into the correlation of lifestyle factors with PCa and highlights the necessity of health professionals in encouraging their patients to adopt healthier lifestyles, while offering important insights into awareness, prevention, and alternative screening, diagnosis, and treatment methods, which could help reduce false positives and treatment side effects.

Role of lifestyle factors on the development and long-term prognosis of pneumonia and cardiovascular disease in the Chinese population.

Whether adherence to a healthy lifestyle is associated with a lower risk of developing pneumonia and a better long-term prognosis remains unclear. This study aimed to investigate associations of individual and combined lifestyle factors (LFs) with the incidence risk and long-term prognosis of pneumonia hospitalization. Using data from the China Kadoorie Biobank study, we used the multistate models to investigate the role of five high-risk LFs, including smoking, excessive alcohol drinking, unhealthy dietary habits, physical inactivity, and unhealthy body shape, alone or in combination in the transitions from a generally healthy state at baseline to pneumonia hospitalization or cardiovascular disease (CVD, regarded as a reference outcome), and subsequently to mortality. Most of the five high-risk LFs were associated with increased risks of transitions from baseline to pneumonia and from pneumonia to death, but with different risk estimates. The greater the number of high-risk LFs, the higher the risk of developing pneumonia and long-term mortality risk after pneumonia, with the strength of associations comparable to that of LFs and CVD. Compared to participants with 0-1 high-risk LF, the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for transitions from baseline to pneumonia and from pneumonia to death in those with five high-risk LFs were 1.43 (1.28-1.60) and 1.98 (1.61-2.42), respectively. Correspondingly, the respective HRs (95% CIs) for transitions from baseline to CVD and from CVD to death were 2.00 (1.89-2.11) and 1.44 (1.30-1.59), respectively. The risk estimates changed slightly when further adjusting for the presence of major chronic diseases. In this Chinese population, unhealthy LFs were associated with an increased incidence and long-term mortality risk of pneumonia.

Temporomandibular disorder pain is associated with increased sick leave and reduced health related quality of life.

Temporomandibular disorders (TMD) are the most common reason for chronic pain in the orofacial area and significantly impact the lives of those affected. The role of lifestyle factors in TMD, however, remains less explored. This cohort study aims to estimate TMD prevalence by addressing potential selection biases and to evaluate the association between TMD and lifestyle factors with a specific focus on sick leave and health related quality of life. By linking data on TMD in the general population in Västerbotten, northern Sweden (n = 180,000) to health survey data (n = 120,000), information on sociodemographic factors and quality of life was available for 52,961 individuals (50.6% women) with a mean age of 53 years. We applied inverse probability weighting to adjust for selection bias and Poisson regression to explore associations with TMD. TMD prevalence was 9.2% during the study period, being higher in women (12.9%) than men (5.4%). Weighting for varying visiting frequencies did not affect TMD prevalence (average difference 0.4% points). Individuals with TMD, especially women, reported more sick leave and use of pain medication, with a significant association between TMD and increased sick leave (prevalence ratio 1.89, 95% CI: 1.78-2.01) among both women and men. In addition, TMD was associated with a lower health related quality of life (p < 0.001). The association of TMD with sick leave highlights the condition's profound impact on the lives of affected individuals. These findings underscore the influence of TMD on work life and the burden of TMD on the societal level. The findings provide insight into how TMD affect individuals, by incorporating lifestyle factors, social determinants and the impact of sick leave at a population level. By incorporating these areas into the study of TMD, we can deepen our understanding of how TMD affects individuals' lives. This approach may also create opportunities to develop more comprehensive strategies to address TMD, focusing on broader implications beyond the clinical symptoms.

The impact of baseline health factors on second primary cancer risk after radiotherapy for prostate cancer.

In evaluating second primary cancers (SPCs) following External Beam Radiotherapy (EBRT), the role of lifestyle factors is frequently not considered due to data limitations. We investigated the association between smoking, comorbidities, and SPC risks within EBRT-treated patients for localized prostate cancer (PCa). The study included 1,883 PCa survivors aged 50-79, treated between 2006 and 2013, with intensity-modulated radiotherapy (IMRT) or three-dimensional conformal radiotherapy (3D-CRT). Clinical data were combined with SPC and survival data from the Netherlands Cancer Registry with a 12-month latency period. Standardized Incidence Ratios (SIRs) were calculated comparing the EBRT cohort with the general Dutch population. To explore the effect of patient and treatment characteristics on SPCs we conducted a Cox regression analysis. Lastly, we estimated cumulative incidences of developing solid SPC, pelvis SPC, and non-pelvis SPC using a competing risk analysis. Significantly increased SIRs were observed for all SPC (SIR = 1.21, 95% confidence interval [CI]: 1.08-1.34), pelvis SPC (SIR = 1.46, 95% CI: 1.18-1.78), and non-pelvis SPC (SIR = 1.18, 95% CI [1.04-1.34]). Smoking status was significantly associated with pelvic and non-pelvic SPCs. Charlson comorbidity index (CCI) ≥ 1 (Hazard Ratio [HR] = 1.45, 95% CI: 1.10-1.91), cardiovascular disease (HR = 1.41, 95% CI: 1.05-1.88), and chronic obstructive pulmonary disease (COPD) (HR = 1.91, 95% CI: 1.30-2.79) were significantly associated with non-pelvis SPC. The proportion of active smoking numbers in the cohort was similar to the general population. We conclude that the presence of comorbidities in the EBRT population might be a relevant factor in observed excess non-pelvis SPC risk, but not for excess pelvis SPC risk.

Evaluating perceived side effects of SARS-CoV2 mRNA vaccines by lifestyle factors and nutritional status: Perspectives from a pilot study

Nutritional status, sex, and physical activity have been implicated in severe COVID-19 illness; however, the role of lifestyle factors and nutritional status in determining an individual's response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccines is less well characterized. We evaluated whether self-reported side effects following SARS-CoV2 vaccination differed by body mass index (BMI) and lifestyle factors. We further evaluated whether associations between lifestyle, nutritional status, and self-reported side effects differed by sex or use of hormone-based medications. A survey was administered between May–September 2021 to collect respondents' self-reported demographics, dietary patterns, physical activity, medication and supplement use, history of COVID-19 illness, and SARS-CoV2 vaccine side effects. A total of 82 participants (61.2 % female, 38.8 % male) completed the survey and were included in the final analysis. Females trended toward reporting a greater level of subjective stress (71 %) and engaged in less physical activity (43.2 %) compared to males. While severity of COVID-19 illness and vaccine side effects did not differ by sex and there were no differences in dietary patterns between individuals reporting mild vs. more severe side effects, individuals with a higher BMI trended toward reporting a greater severity of vaccine side effects. Survey participants who engaged in physical activity for more than 30 min per day trended toward reporting a lower severity of side effects compared to those exercising for 30 min a day or less after the first dose (86.7 % vs. 50.0 %), whereas the opposite trend was observed following the second mRNA vaccine dose. In addition, survey participants reporting higher stress levels experienced a greater severity of side effects of the first SARS-CoV2 mRNA vaccine dose compared to those reporting lower stress levels (42.9 % vs. 2.0 %). Further, a greater percentage (75 %) of respondents taking combined oral contraceptives reported experiencing side effects following the first SARS-CoV2 mRNA vaccine dose, whereas participants not using hormone-based contraceptives were more likely to report not experiencing side effects (61.3 %). Together, our findings suggest that self-reported side effects from SARS-CoV2 mRNA vaccines differ by lifestyle characteristics and use of combined oral contraceptives. Further investigation is warranted to determine whether targeting these lifestyle factors is an effective strategy to mitigate vaccine side effects, and whether public health education pertaining to lifestyle and anticipated side effects may reduce the barriers to vaccine acceptance.

The role of lifestyle factors in the association between education and self-reported fibromyalgia: a mediation analysis

BackgroundSocioeconomic status as measured by education, income, or occupation, has been associated with fibromyalgia but the underlying mechanism and the role of lifestyle factors are unclear. Thus, we examine the role of modifiable lifestyle factors (body mass index, physical activity, alcohol consumption and smoking) in the association between education and self-reported fibromyalgia.MethodsWe used data from 74,157 participants in the population-based prospective Norwegian Women and Cancer (NOWAC) study. Socioeconomic position, operationalized as years of educational attainment, and lifestyle factors were assessed via self-reported questionnaires. Multiple mediation analysis was used to decompose total effects into direct and indirect effects. Estimates were reported as hazard ratios (HRs) with 95% confidence intervals (CIs).ResultsThe cumulative incidence of fibromyalgia was 3.2% after a median follow up time of 13 years. Fibromyalgia was inversely associated with years of educational attainment for ≤ 9 years (HR = 2.56; 95% CI 2.32–2.91) and for 10–12 years (HR = 1.84; 95% CI 1.72–2.02), compared with ≥ 13 years of education. Overall, all lifestyle factors together jointly mediated 17.3% (95% CI 14.3–21.6) and 14.1% (95% CI 11.3–18.9) of the total effect for ≤ 9 years and 10–12 years of education, respectively. Smoking and alcohol consumption contributed the most to the proportion mediated, for ≤ 9 years (5.0% and 7.0%) and 10–12 years (5.6% and 4.5%) of education.ConclusionThe association between education and self-reported fibromyalgia was partly explained through lifestyle factors, mainly smoking and alcohol consumption.

IJCM_366A: Role of lifestyle factors in migraine among adolescent students of a senior secondary school in east Sikkim

Background: Migraine can be a debilitating condition. It can manifest as severe throbbing pain, often with nausea, light and sound sensitivity. It can negatively impact school performance and quality of life. Objective: 1. To assess the prevalence of migraine in adolescent students. 2. To check the relation of stress and anxiety as triggers in migraine Methodology: A cross-sectional-study was conducted in a senior secondary school among 200 adolescent students (Class X, XI, XII) via anonymous self-administered questionnaire method. Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) Questionnaire developed by World Health Organization and Headache Triggers Sensitivity and Avoidance Questionnaire-Short Form(HTSAQ-SF) was used. Conclusion: Awareness about stress and anxiety as a trigger for migraine must be emphasized. Measures to manage stress and anxiety may help students manage migraine headache better Results: The prevalence of migraine was 26% among the adolescent students. Among them, anxiety was found to be a trigger for migraine in 58%(p=0.000) (Trigger frequency: Sometimes-31%, Usually-8%, Always-19%). Stress was found to be a trigger in all of them with migraine(p=0.000) (Trigger Frequency- Sometimes-50%, Usually- 15%, Always - 35%).

Trends in psychosomatic symptoms among adolescents and the role of lifestyle factors

BackgroundAdolescent mental health problems are on the rise globally, including in Sweden. One indicator of this trend is increased psychosomatic symptoms (PSS) over time. Lifestyle factors such as physical activity (PA), diet, smoking, and alcohol consumption may influence the time trends in PSS; however, the evidence base is scarce. The aim of this study was to investigate associations between time trends in PSS and lifestyle factors.MethodsThe study was based on data collected from a nationally representative sample of 9,196 fifteen-year-old boys and girls in Sweden using the Health Behavior in School-aged Children (HBSC) symptom checklist. The sample comprised nearly equal proportions of girls (50.5%) and boys. The lifestyle factors examined in this study included PA, regular breakfast intake, consumption of fruits, vegetables, sweets, or soft drinks, smoking, and alcohol drunkenness. We used data from 2002 to 2018 and stratified by family affluence scale (FAS) to demonstrate how the associations varied among the FAS groups. We fitted separate regression models for the high- and low-FAS groups, where interaction terms between the year of survey and each lifestyle factor were used to estimate the level and direction of associations between the factors and trends in PSS.ResultsThere was a generally increasing trend in PSS mean scores from 2.26 in 2002 to 2.49 in 2018 (p <.001). The changes in each survey year compared to the average mean scores during the preceding years were significant in all years except 2010. Regular breakfast intake, daily fruit and vegetable consumption, and higher PA were associated with lower PSS mean scores, while smoking and drunkenness had opposite associations with PSS. The only significant interaction between survey year and the lifestyle factors was observed regarding drunkenness in the high FAS group, suggesting that the association between trends in PSS and the experience of getting drunk at least twice got stronger over time (B = 0.057; CI:0.016, 0.097; p <.01).ConclusionsThe results indicate increasing trends in PSS among young people in Sweden from 2002 to 2018, with a significant increase observed among adolescents in the high FAS group who reported getting drunk on at least two occasions.

APOE Genotype Disclosure Influences Decisions About Future Planning but not Adoption of Healthy Lifestyle Changes in Cognitively Unimpaired Individuals.

Studies have shown apolipoprotein E (APOE) genotype disclosure to be safe and well-tolerated in cognitively unimpaired (CU) older adults. This study aimed to examine the effect of the disclosure process on decisions about future directives and health behaviors in community-dwelling CU older adults from the Butler Alzheimer's Prevention Registry (BAPR). CU APOE E4 non-carriers (n = 106) and carriers (n = 80) aged 58-78 completed in-person psychological readiness screening to undergo APOE disclosure. Follow-up assessments were completed online 3days, 6weeks, and 6months post-disclosure. The primary outcomes were future directives, dietary habits, and physical activity scores. Disclosure was associated with decision making on future directives in E4 carriers (t = 3.59, P = .01) at 6months compared to baseline, but not non-carriers. Family history of memory impairment, SCD endorsement, and education consistently predicted scores on future directives. A significant interaction between E4+ and SCD endorsement on future directive scores was noted (OR = 163.06, 9.5-2,799.8). E4 + carrier status was associated with physical activity (W = 60,148, P = .005) but not dietary habits scores. Our findings indicate that disclosure led to a change in future directives but not protective health behaviors, specifically in E4 carriers. Future work will explore whether pairing disclosure with education about the role of lifestyle factors in AD risk and providing guidelines on making risk-lowering lifestyle modifications as an intervention approach leads to positive change.

The role of lifestyle factors in the association between early-life stress and adolescent psycho-physical health: Moderation analysis in two European birth cohorts

ObjectiveEarly-life stress (ELS) is an established risk factor for a host of adult mental and physical health problems, including both depression and obesity. Recent studies additionally showed that ELS was associated with an increased risk of comorbidity between mental and physical health problems, already in adolescence. Healthy lifestyle factors, including physical activity, sleep and diet have also been robustly linked to both emotional and physical wellbeing. However, it is yet unclear whether these lifestyle factors may moderate the association between ELS and psycho-physical comorbidity. MethodsWe investigated whether (a) participation in physical activity, (b) sleep duration, and (c) adherence to a Mediterranean diet, moderated the relationship between cumulative ELS exposure over the first 10 years of life and psycho-physical comorbidity at the age of 13.5 years. Analyses were conducted in 2022–2023, using data from two large adolescent samples based in the UK (ALSPAC; n = 8428) and The Netherlands (Generation R; n = 4268). ResultsExposure to ELS was significantly associated with a higher risk of developing comorbidity, however this association was not modified by any of the three lifestyle factors investigated. Only physical activity was significantly associated with a reduced risk of comorbidity in one cohort (ORALSPAC [95%CI] = 0.73 [0.59;0.89]). ConclusionsIn conclusion, while we found some evidence that more frequent physical activity may be associated with a reduction in psycho-physical comorbidity, we did not find evidence in support of the hypothesised moderation effects. However, more research is warranted to examine how these associations may evolve over time.

Association of the rs236918 variant of PCSK7 with the prevalence of the metabolic syndrome and its components in population from Ahvaz cohort study: A case-control study in Iran

Objectives: The proprotein convertase subtilisin/kexin type 7 (PCSK7) enzyme is encoded by the PCSK7 gene and is involved in the processing and activation of latent precursor proteins. Previous studies have reported that some PCSK7 variants are associated with markers of body iron stores and lipid profiles, as well as obesity and insulin resistance. The aim of this study was to investigate the association of the rs236918 variant of PCSK7 with metabolic syndrome (MetS) and its related components.&#x0D; Methods: In this cross-sectional study, 325 participants in the age group of 25 to 86 years were examined. Standard protocols were employed to measure body mass index, blood pressure, fasting blood glucose, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG). Individuals with metabolic syndrome (MetS) were identified in accordance with the guidelines set by the National Cholesterol Education Program. Genotype was determined using the PCR-RFLP method.&#x0D; Results: The findings revealed that there was no association between the rs236918 variant and increased risk of MetS or its components and also plasma lipid profile.&#x0D; Conclusion: Overall, the findings exhibit no significant association between the PCSK7 rs236918 polymorphism and MetS in this population. Although these results may be due to sample size and power issues, the role of lifestyle factors and other genes in the development of MetS appears to be more important in this population. Therefore, further research is required to validate these results.

A case control study of risk factors in chronic urticaria

Urticaria presents as erythematous, often pruritic, raised transient wheals. The aetiology of Chronic Urticaria (CU) is not well understood. Autoimmunity, chronic infections, allergens and metabolic syndrome are some known implicated factors. But the role of life style factors like diet, smoking, alcohol, occupation, family history etc is relatively unknown. This study aims to uncover the role of these modifiable factors in causation of CU.Data from 20 individuals with chronic urticaria (duration &amp;#60;1 year) and 20 age and sex matched Controls (healthy/patients without chronic urticaria) was collected using questionnaires to assess lifestyle and risk factors like diet, alcohol consumption, smoking, medications, stress, sleep etc in the implication of CU.Our study revealed notable if not significant associations. Out of these, 6 cases (30%) had a family history of CU, while 10 cases (50%) had a prior history of acute urticaria episodes. Additionally, 6 cases (30%) reported food allergies, and 10 cases (50%) had a documented medical history. Furthermore, 7 cases (35%) reported insect bites as a factor, while 1 case (5%) was linked to H. Pylori infections. Notably, 12 cases (60%) showed a lower consumption of fruits, while 9 cases (45%) exhibited a relatively higher intake of foods containing dyes and additives. These findings collectively suggest some potential connections in the development of CU.This study underscores the intricate connections between risk factors, lifestyle choices, and CU. Differences in sleep quality, food allergies, dietary habits, and seafood consumption provide potential insights into associations. This investigation may contribute to improved CU management approaches.

Chronicles of the midnight strain: Exploring graveyard shift stress and its impact on employee burnout in call centers

This study, titled “Chronicles of the Midnight Strain: Exploring Graveyard Shift Stress and Its Impact on Employee Burnout in Call Centers,” delves into the intricate relationship between the demanding nature of graveyard shift work in call centers and its potential consequences on employee burnout. The research adopts a comprehensive approach, investigating various factors such as electronic performance monitoring, job demands, physiological indicators, and the role of lifestyle factors in cardiovascular health. Drawing from a vast array of literature, the study explores the causal links and mechanisms of action, emphasizing the significant role of sleep disruption and circadian rhythm desynchronization in contributing to cardiovascular disease among shift workers. Additionally, it considers the impact of stress, working hours, and dietary patterns on the overall well- being of employees working during the unconventional hours of the night. The study reviews existing theories proposing connections between shiftwork, sleep loss, and cardiovascular diseases. It scrutinizes factors like inflammation, blood coagulation, cardiac autonomic function, and the interplay between stress-related hormones and cardiovascular health. Multiple hypotheses are examined, including the influence of a stressful work environment, disturbed sleep on the immune system, and lifestyle factors such as dietary habits and substance use. Despite over two decades of continuous research, the findings in this area remain inconclusive regarding the precise role of shiftwork in cardiovascular disease. The study aims to contribute valuable insights into mitigating the potential adverse effects of graveyard shift stress on employee burnout in call centers, providing a foundation for further research and the development of targeted interventions.

Age at cardiovascular disease onset, dementia risk, and the role of lifestyle factors.

We first examined the role of age at cardiovascular disease (CVD) onset for incident dementia, and then examined whether lifestyle factors at guideline-recommended levels in individuals with CVD mitigates dementia risk. We used population-based data (Whitehall II: n=10,308/baseline 1985-1988/examinations every 4-5 years). Lifestyle factors (non-smoking, body mass index [BMI], physical activity, diet) were extracted post-CVD. Over a median of 31.6 years, 3275 (32.1%) developed CVD. At age 70, risk of dementia was higher in individuals with CVD onset before (hazard ratio [HR] of incident dementia for participants with CVD before age 60, using participants without CVD at age 70 as the reference: 1.56, 95% confidence interal [CI] 1.18-2.08) but not after 60 years. In participants with CVD, a greater number of lifestyle factors at recommended levels post-CVD was associated with a lower dementia risk (per lifestyle factor at recommended level HR: 0.73, 95% CI 0.59-0.92). Our results suggest that early onset CVD is associated with a higher dementia risk at older ages. In those with CVD, the dementia risk was lower if lifestyle factors are at recommended levels following CVD diagnosis. CVD in midlife but not in late life is associated with a higher risk of dementia. Dementia risk in CVD patients is lower if their lifestyle factors are at recommended levels. These findings provide evidence to promote CVD prevention in midlife or earlier. Study findings also show the importance of a healthy lifestyle in those with CVD.

Trends in adolescent mental health problems and the role of lifestyle factors

Abstract Background Adolescent mental health problems are on the rise globally, including in Sweden. One indicator is an increase in psychosomatic symptoms (PSS) over time. Lifestyle factors such as physical activity (PA), diet, smoking, and alcohol consumption may influence the trends in PSS. However, we found limited research on such associations. Methods This study is based on data collected every four years from nationally representative samples of 15-year-old boys and girls in Sweden (N = 9,196, 50.5% girls), as part of the Health Behavior in School-aged Children (HBSC) study. PSS was measured using a scale developed from the HBSC symptom checklist. We analyzed the trends in PSS from 2002 to 2018 and fitted models to investigate the associations between the trends and lifestyle factors. We included interaction terms between time and each lifestyle factor and fitted separate models for the high and low socioeconomic status (SES) groups. Results In general, the mean scores for PSS increased from 2.26 in 2002 to 2.49 in 2018 (p&amp;lt;.001). Compared to the average mean scores during preceding years, the changes in PSS mean scores at each survey year were also significant in all years except 2010. More frequent breakfast intake, daily consumption of fruits and vegetables, and higher PA were associated with lower PSS mean scores while smoking and alcohol consumption had the opposite association. The only significant interaction (B = .050; CI: .015, ¬ .085; p&amp;lt;.01) was observed in the high SES group, indicating that the increasing trend in PSS was stronger among those who had been drunk once or more in a lifetime, compared to those who had never been drunk. Conclusions The results indicate increasing trends in mental health problems among young people in Sweden. Furthermore, the study revealed that alcohol drunkenness was associated with a more substantial rise in PSS over time among those in the high SES group. Further research is needed to understand the reasons behind these findings. Key messages • Psychosomatic complaints have increased among Swedish adolescents in recent decades. • Although alcohol drunkenness has significantly declined among Swedish adolescents, it was not sufficient to influence trends in psychosomatic symptoms among those in the high socioeconomic group.
