Evidence based review of type 2 diabetes prevention and management in low and middle income countriesAim: To identify the newest approaches to type 2 diabetes (T2DM) prevention and control in the developing world context. Methods: We conducted a systematic review of published studies of diabetes prevention and control programs in low and middle-income countries, as defined by the World Bank. We searched PubMed using Medical Subject Headings terms. Studies needed to satisfy four criteria: (1) Must be experimental; (2) Must include patients with T2DM or focusing on prevention of T2DM; (3) Must have a lifestyle intervention component; (4) Must be written in English; and (5) Must have measurable outcomes related to diabetes. Results: A total of 66 studies from 20 developing countries were gathered with publication dates through September 2014. India contributed the largest number of trials (11/66). Of the total 66 studies reviewed, all but 3 studies reported evidence of favorable outcomes in the prevention and control of type 2 diabetes. The overwhelming majority of studies reported on diabetes management (56/66), and among these more than half were structured lifestyle education programs. The evidence suggests that lifestyle education led by allied health professionals (nurses, pharmacists) were as effective as those led by physicians or a team of clinicians. The remaining diabetes management interventions focused on diet or exercise, but the evidence to recommend one approach over another was weak. Conclusion: Large experimental diabetes prevention/control studies of dietary and exercise interventions are lacking particularly those that consider quality rather than quantity of carbohydrates and alternative exercise.

A real-world evaluation of a tertiary care childhood obesity intervention to reduce metabolic risk in a hard-to-reach urban populationBackground: Research on outcomes associated with lifestyle interventions serving pediatric populations in urban settings, where a majority have severe obesity, is scarce. This study assessed whether participation in a lifestyle intervention improved body mass index (BMI) percentile, BMI z-score, blood pressure, and lipid levels for children and adolescents. Methods: The Live Light Live Right program is a lifestyle intervention that uses medical assessment, nutritional education, access to physical fitness classes, and behavioral modification to improve health outcomes. Data was analyzed for 144 subjects aged 2-19 who participated for a minimum of 12 consecutive months between 2002 and 2016. McNemar tests were used to determine differences in the proportion of participants who moved from abnormal values at baseline to normal at follow-up for a given clinical measure. Paired sample t-tests assessed differences in blood pressure and lipid levels. Multiple linear regression assessed the change in blood pressure or lipid levels associated with improvement in BMI%95 and BMI z-score. Results: The majority were female (62.5%), mean age was 9.6, and 71% were Black. At baseline, 70.1% had severe obesity, systolic hypertension was present in 44, and 13.9% had diastolic hypertension. One-third had abnormally low high-density lipoprotein (HDL) at baseline, 35% had elevated low-density lipoprotein (LDL), and 47% had abnormal total cholesterol (TC). The average difference in percentage points of BMI%95 at follow-up compared was - 3.0 (95% CI: - 5.0, - 1.1; p < 0.003). The mean difference in BMI z-score units at follow-up was - 0.15 (95% CI: - 0.2, - 0.1; p < 0.0001). Participants with systolic or diastolic hypertension had an average improvement in blood pressure of - 15.3 mmHg (p < 0.0001) and - 9.6 mmHg (p < 0.0001), respectively. There was a mean improvement of 4.4 mg/dL for participants with abnormal HDL (p < 0.001) and - 7.8 mg/dL for those with abnormal LDL at baseline (p = 0.036). For those with abnormal baseline TC, a one-unit improvement in BMI%95 was associated with a 0.61 mg/dL improvement in TC while holding constant age, contact hours, and months since enrollment (p = 0.043).

Implementation of a Case Investigation and Contact Tracing Program at an Academic Medical Center in New York CityProblem: In the spring of 2020, New York City was an epicenter of COVID-19 infections, hospitalizations, and mortality. One of the hardest hit areas in New York City was central Brooklyn, where State University of New York (SUNY) Downstate is located. As the severity of the initial wave of the COVID-19 pandemic waned in New York City, SUNY Downstate Health Sciences University planned to institute COVID-19 surveillance on campus to limit its spread among employees and students. Approach: In collaboration with university leadership and students across schools, the SUNY Downstate Contact Tracing Corps was established in July 2020. Using guidance from the Centers for Disease Control and Prevention and the New York State Department of Health, protocols for case and contact investigations, including scripts, were developed. Students were recruited and trained in remote and confidential case and contact investigations. Outcomes: From August 1, 2020, to March 23, 2021, there were 185 COVID-19 cases referred to the contact tracing program; of these, 180 were successfully investigated and isolated (97%). Case investigations identified 111 Downstate close contacts; 105 were investigated and quarantined (94.5%). There were 122 exposure-only investigations referred to the program, and 121 were successfully investigated and quarantined (99%). Next steps: The SUNY Downstate Contact Tracing Corps transitioned to a core group of tracers in January 2021 and has been maintained at 4 to 6 tracers since that time. With the emergence of COVID-19 variants, the threat of new variants, and variable COVID-19 vaccination rates across Brooklyn, Downstate employees and students remain vulnerable to COVID-19 transmission. Given this, the SUNY Downstate Contact Tracing Corps will continue to conduct case and contact investigations.

Insights into the challenges and facilitators to physical activity among brooklyn teens enroled in a weight management programmePurpose: A qualitative study was carried out to explore obese adolescents' understanding of physical activity, perceptions of the ideal body type and to identify facilitators of and barriers to physical activity. Methods: Twenty-two adolescents 12-18 years of age and 14 of their parents were recruited from an obesity intervention programme in Brooklyn, New York, from June to November 2017. Data were collected using focus groups and individual semi-structured interviews, followed by interpretative phenomenological analysis of the transcripts. Results: The adolescents wanted to 'lose some weight', but not to be 'thin' or 'look hungry'. Most females desired a 'slim-thick' figure, which was 'a flat stomach with big thighs, and curvy'. Fun and support from parents, peers and programme staff facilitated achieving their physical activity goals. Barriers included low self-efficacy, inactive families, fear of neighbourhood gangs and crime and perceptions that the parks were small and overcrowded, with limited physical activity options for adolescents. Conclusion: These findings highlight the need to consider local norms concerning body image when designing obesity interventions. To effectively reduce childhood obesity in New York City, policy should prioritize the promotion of public safety, improvement of neighbourhood parks and increase options for physical activity. Patient or public contribution: The voices and narratives of patients and their families informed this study.

Evaluation of a Childhood Obesity Program Serving a High-Need Population in Brooklyn, New York Using Survival AnalysisIn this study, we used survival analysis to evaluate whether contact hours intensity was associated with a reduction in time to improvement of various BMI metrics over a 5-year follow-up period at the Live Light Live Right pediatric obesity program in Brooklyn, New York. This was a single-center retrospective longitudinal study of 406 patients during 2010-2016. Participants were categorized based on hours of exposure to Live Light Live Right's interventions; high contact hours (≥50 h) vs. low contact hours (<50 h). At baseline, 88% of patients in the high contact hour group had severe obesity and the mean age for this group was 10.0 ± 2.66. High contact hours were independently associated with a shorter time to BMI improvement in the sample. There was also a significant association between high contact hours and a longer duration in the improved state. Survival analysis was successful in evaluating the efficacy of the Live Light Live Right Program and demonstrated a positive association between greater intervention intensity and a healthier metabolic profile. Patients' active engagement in a robust treatment model exemplified by Live Light Live Right is recommended to address the childhood obesity crisis in central Brooklyn.

Community Perceptions of Health Equity: A Qualitative StudyIntroduction: Notable inequities in patient experiences exist in the healthcare system. Communities with a large concentration of blacks and immigrants are often marginalized rather than centralized in the healthcare system. These inequities may fuel distrust and exacerbate adverse outcomes, thereby widening the health gap. Addressing differences in patients' experiences of care is paramount for reducing health inequities. Methods: In this qualitative study, we used a purposive sampling method to recruit 62 participants to conduct 10 FGs (44 participants total) and 18 key informant interviews with stakeholders across Central Brooklyn. Results: The data revealed three primary themes: Trust, Discrimination, and Social Determinants of Health (SDOHs). Each theme comprised subthemes as follows: For Trust, the subthemes included (1) confidence in the healthcare professional, (2) provider empathy, and (3) active participation in healthcare decisions. Regarding Discrimination, the subthemes involved (1) racism and identity, as well as (2) stigma related to diagnosis, disease state, and pain management. Lastly, for Social Determinants of Health, the key subtheme was the acknowledgment by providers that patients encounter competing priorities acting as barriers to care, such as housing instability and food insecurity. For the first theme, participants' interactions with the healthcare system were prompted by a necessity for medical attention, and not by trust. The participants reported that experiences of discrimination resulting from identity and stigma associated with diagnosis, disease state, and pain management amplified the disconnect between the community, the patients, and the healthcare system. This also exacerbated the poor healthcare experiences suffered by many people of color. For SDOHs, the participants identified housing, food security, and other various social factors that may undermine the effectiveness of the healthcare that patients receive. Conclusions: Improvements in the health system, based on feedback from patients of color regarding their unique care experiences, are important initiatives in combating inequities in healthcare.

Do digital health interventions hold promise for stroke prevention and care in Black and Latinx populations in the United States? A scoping reviewBackground: Black and Latinx populations are disproportionately affected by stroke and are likely to experience gaps in health care. Within fragmented care systems, remote digital solutions hold promise in reversing this pattern. However, there is a digital divide that follows historical disparities in health. Without deliberate attempts to address this digital divide, rapid advances in digital health will only perpetuate systemic biases. This study aimed to characterize the range of digital health interventions for stroke care, summarize their efficacy, and examine the inclusion of Black and Latinx populations in the evidence base. Methods: We searched PubMed, the Web of Science, and EMBASE for publications between 2015 and 2021. Inclusion criteria include peer-reviewed systematic reviews or meta-analyses of experimental studies focusing on the impact of digital health interventions on stroke risk factors and outcomes in adults. Detailed information was extracted on intervention modality and functionality, clinical/behavioral outcome, study location, sample demographics, and intervention results. Results: Thirty-eight systematic reviews met inclusion criteria and yielded 519 individual studies. We identified six functional categories and eight digital health modalities. Case management (63%) and health monitoring (50%) were the most common intervention functionalities. Mobile apps and web-based interventions were the two most commonly studied modalities. Evidence of efficacy was strongest for web-based, text-messaging, and phone-based approaches. Although mobile applications have been widely studied, the evidence on efficacy is mixed. Blood pressure and medication adherence were the most commonly studied outcomes. However, evidence on the efficacy of the various intervention modalities on these outcomes was variable. Among all individual studies, only 38.0% were conducted in the United States (n = 197). Of these U.S. studies, 54.8% adequately reported racial or ethnic group distribution. On average, samples were 27.0% Black, 17.1% Latinx, and 63.4% White. Conclusion: While evidence of the efficacy of selected digital health interventions, particularly those designed to improve blood pressure management and medication adherence, show promise, evidence of how these interventions can be generalized to historically underrepresented groups is insufficient. Including these underrepresented populations in both digital health experimental and feasibility studies is critical to advancing digital health science and achieving health equity.

Community design of the Brooklyn Health Equity IndexHealth equity drives quality care. Few reliable metrics that capture patients' perceptions of health equity exist. We report on the development of a patient-centered metric for health systems change in central Brooklyn, which stands out as an outlier in New York City with a disproportionate burden of poverty, disease, and death. A community-engaged, sequential, mixed-methods research design was used. Qualitative interviews were conducted with 80 community and health care stakeholders across central Brooklyn. Candidate items were derived from qualitative themes and examined for face, interpretive validity, and language. Interitem reliability and confirmatory factor analysis was assessed using data collected via text and automated discharge calls among 368 patients from a local hospital. Qualitative data analysis informed the content of 11 draft questions covering 3 broad domains: trust-building, provider appreciation of social determinants of health, and experiences of discrimination. Psychometric testing resulted in a Cronbach's alpha of 0.774 and led to deletion of 1 item, resulting in a 10-item Brooklyn Health Equity Index (BKHI). The 10-item BKHI is a novel, brief, and reliable measure that captures patients' perceptions of inequities and offers a real-time measure for health systems and payors to monitor progress toward advancing health equity.

Diabetes and Hypertension Risk Across Acculturation and Education Levels in Hispanic/Latino AdultsImportance: Acculturation among Hispanic/Latino populations, defined as adaptation to US lifestyle and culture, is often assumed to lead to adverse health outcomes that will reduce the immigrant health advantage. Objective: To evaluate the risks for incident diabetes and hypertension by levels of acculturation and educational attainment. Design, setting, and participants: This study used data from the Hispanic Community Health Study/Study of Latinos, a population-based cohort study of men and women aged 18 to 74 years who identified as Central American, Cuban, Dominican, Mexican, Puerto Rican, or South American living in 4 urban locales in the US. Visit 1 spanned March 2008 to June 2011; visit 2 spanned October 2014 to December 2017. Main outcomes and measures: Multivariable logistic regression was used to evaluate the association between language acculturation level defined by the Short Acculturation Scale for Hispanics (SASH) and educational attainment (less than high school graduate vs more than high school) and incident diabetes and hypertension by heritage group. Results: Of 11 623 adult participants, 1207 (10.4%) were of Central American heritage, 1645 (14.2%) of Cuban heritage, 1021 (8.8%) of Dominican heritage, 11 623 (41.3%) of Mexican heritage, 1801 (15.5%) of Puerto Rican heritage, and 795 (6.8%) of South American heritage. The mean (SE) age of all participants was 43.1 (0.3) years, and 7345 (56.3%) were female. A total of 8697 (71.4%) were born outside the US, 4358 (32.5%) had less than a high school education, and 7475 (58.3%) were less acculturated (SASH score less than 2). Incident rates of diabetes (total cohort, 14.6% [95% CI, 13.6%-15.6%]) and hypertension (total cohort, 20.4% [95% CI, 19.0%-21.9%]) varied across heritages; Mexican individuals (17.2% [95% CI, 15.5%-19.0%]) had the highest diabetes incidence and Dominican individuals the highest hypertension incidence (27.1% [95% CI, 22.7%-31.4%]). Persons with more educational attainment were at lower risk for diabetes and hypertension independent of acculturation, and more acculturated participants had a lower risk for incident diabetes. Less acculturated with lower socioeconomic status (SES) were more likely to have incident diabetes (weighted predicted probability [WPP], 0.17 [95% CI, 0.14-0.19]), and more acculturated with lower SES had the highest predicted probability of hypertension (WPP, 0.19 [95% CI, 0.15-0.23]). More acculturated with higher SES were at lower risk of diabetes (WPP, 0.11 [95% CI, 0.09-0.13]) and had a lower predicted probability of hypertension (WPP, 0.10 [95% CI, 0.08-0.12]). Conclusions and relevance: In this cohort study, the association of acculturation with health outcomes is not unidirectional and interacts with educational attainment in determining incident diabetes and hypertension. The Hispanic and Latino paradox, in which immigrants have a health advantage, is influenced by more factors than acculturation and may persist with higher educational attainment. These observations may inform prevention and treatment strategies associated with cardiometabolic health in Hispanic/Latino populations.

Effectiveness of modified vaccinia Ankara-Bavarian Nordic vaccine against mpox infection: emulation of a target trialObjective: To estimate the real world effectiveness of modified vaccinia Ankara-Bavarian Nordic (MVA-BN) vaccine against mpox infection. Design: Emulation of a target trial. Setting: Linked databases in Ontario, Canada. Participants: 9803 men aged ≥18 years with a history of being tested for syphilis and a laboratory confirmed bacterial sexually transmitted infection (STI) in the previous year, or who filled a prescription for HIV pre-exposure prophylaxis in the previous year. On each day between 12 June 2022 and 27 October 2022, those who had been vaccinated 15 days previously were matched 1:1 with unvaccinated men by age, geographical region, past HIV diagnosis, number of bacterial STI diagnoses in the previous three years, and receipt of any non-MVA-BN vaccine in the previous year. Main outcome measure: The main outcome measure was vaccine effectiveness ((1-hazard ratio)×100) of one dose of subcutaneously administered MVA-BN against laboratory confirmed mpox infection. A Cox proportional hazards model was used to estimate hazard ratios to compare the rate of laboratory confirmed mpox between the two groups. Results: 3204 men who received the vaccine were matched to 3204 unvaccinated controls. A total of 71 mpox infections were diagnosed, with 0.09 per 1000 person days (95% confidence interval (CI) 0.05 to 0.13) in the vaccinated group and 0.20 per 1000 person days (0.15 to 0.27) in the unvaccinated group over the study period of 153 days. Estimated vaccine effectiveness of one dose of MVA-BN against mpox infection was 58% (95% CI 31% to 75%). Conclusion: The findings of this study, conducted in the context of a targeted vaccination programme and evolving outbreak of mpox, suggest that one dose of MVA-BN is moderately effective in preventing mpox infection.

Association between maternal mRNA covid-19 vaccination in early pregnancy and major congenital anomalies in offspring: population based cohort study with sibling matched analysisObjective: To examine the association between maternal mRNA covid-19 vaccination during the first trimester of pregnancy and the prevalence of major congenital anomalies in offspring. Design: Population based cohort study with sibling matched analysis. Setting: Multiple health administrative databases, linked and analysed at ICES, an independent, non-profit research institute that collects and analyses healthcare and demographic data, Ontario, Canada, from 16 October 2021 to 1 May 2023. Population: 174 296 singleton live births >20 weeks' gestation with an expected birth date between 16 October 2021 and 1 May 2023: 34 181 (20%) born to mothers who received one or two doses of an mRNA covid-19 vaccine in the first trimester and 34 951 (20%) born to mothers who did not receive a vaccine before or during pregnancy. The sibling matched analysis included 13 312 infants exposed to a covid-19 vaccine in the first trimester and 15 089 matched older siblings with the same mother, with an expected birth date after 16 October 2016 and no reported in utero exposure to a covid-19 vaccine. Main outcome measures: Major congenital anomalies, overall and grouped by specific organ systems, diagnosed within 28 days of birth. Results: Major congenital anomalies were present in 832 (24.3 per 1000 live births) infants exposed to an mRNA covid-19 vaccine in the first trimester compared with 927 (26.5 per 1000 live births) infants not exposed to a vaccine, resulting in an adjusted prevalence ratio of 0.89 (95% confidence interval (CI) 0.79 to 1.01). Major congenital anomalies were present in 283 (21.3 per 1000 live births) and 343 (22.7 per 1000 live births) infants exposed to an mRNA covid-19 vaccine in the first trimester and their older siblings not exposed to a vaccine, respectively (adjusted prevalence ratio 0.91, 95% CI 0.77 to 1.07). First trimester vaccination was not associated with an increase in major congenital anomalies grouped by specific organ system in the primary or sibling matched analyses. Results were similar across a range of subgroup and sensitivity analyses. Conclusions: In this large population based cohort study and sibling matched analysis, mRNA covid-19 vaccination during the first trimester of pregnancy was not associated with an increase in major congenital anomalies in offspring, overall or grouped by organ system.

COVID-19 vaccine effectiveness against severe omicron-related outcomes in children aged 5 to 11 years in Ontario: A Canadian immunization research network (CIRN) studyBackground: Understanding how the efficacy of COVID-19 vaccines translates from clinical trials to real-world settings is critical to inform evolving vaccination policies. The objective of this study was to assess COVID-19 vaccine effectiveness (VE) against severe COVID-19-related outcomes in children aged 5-11 years, including COVID-19-related hospital admissions and multisystem inflammatory syndrome in children (MIS-C). Methods: We conducted a retrospective, population-based cohort study using linked health administrative data in the first year following the emergence of the Omicron variant (January 2 to December 31, 2022) in Ontario, Canada. Baseline differences between subgroups of interest were compared using standardized differences. We used multivariable Cox proportional hazard regression models to estimate VE by time since last vaccine dose by treating vaccination as a time-varying exposure, compared to unvaccinated children. Results: We included a total of 1,058,740 children, of which 583,867 (55.1 %) had received at least one vaccine dose by the end of the study period. In total, there were 185 COVID-19-related hospital admissions and 39 cases of MIS-C. The rate of COVID-19-related admission was substantially higher in children with an underlying comorbid condition compared to children who were previously healthy (adjusted hazard ratio [aHR] = 4.77, 95 %CI, 3.56-6.38). VE against COVID-19-related admission ranged from 93 % (95 %CI, 52-99 %) 7-29 days after a second dose to 63 % (95 %CI; 41-77 %) ≥120 days after a second dose. There was no statistically significant difference in the rate of MIS-C in children who received at least one dose of the vaccine compared to unvaccinated children (aHR = 0.71; 95 %CI, 0.38-1.34). Conclusions: We found that, for children aged 5-11 years, VE against COVID-19-related hospitalization was high in the first four months after a second dose. Children with comorbid conditions were found to be at much higher risk of COVID-19-related severe outcomes and thus may benefit most from COVID-19 vaccination.

Association between ambulatory blood pressure and alternative formulations of job strain.Objectives: The goal of the study was to determine whether alternative formulations of Karasek & Theorell's job-strain construct are associated with ambulatory blood pressure and the risk of hypertension. Methods: Full-time male employees (N = 262) in eight worksites completed a casual blood pressure screening, medical examinations, and questionnaires and wore an ambulatory blood pressure monitor for 24 h on a workday. Cases of hypertension were ascertained from casual blood pressure readings for a case-referent analysis. A cross-sectional analysis was also conducted, ambulatory (continuous) blood pressure measurements being used as the outcome. Results: All formulations of job strain exhibited significant associations with systolic blood pressure at work and home, but not with diastolic blood pressure. Employees experiencing job strain had a systolic blood pressure that was 6.7 mm Hg (approximately 0.89 kPa) higher and a diastolic blood pressure that was 2.7 mm Hg (approximately 0.36 kPa) higher at work than other employees, and the odds of hypertension were increased [odds ratio (OR) 2.9, 95% confidence interval (95% CI) 1.3-6.6]. Using national means for decision latitude and demands to define job strain increased the systolic and diastolic blood pressure associations to 11.5 mm Hg (approximately 1.53 kPa) and 4.1 mm Hg (approximately 0.54 kPa), respectively. Adding organizational influence to the task-level decision latitude variable produced a stronger association for hypertension with job strain (OR 3.7, 95% CI 1.6-8.5). Adding social support to the job-strain model also slightly increased the hypertension risk. Conclusions: The impact of job strain, at least on systolic blood pressure, is consistent and robust across alternative formulations, more restrictive cut points tending to produce stronger effects.

Clinical experience and results of a Sentinel Health Investigation related to indoor fungal exposure.This is a review of exposure conditions, clinical presentation, and morbidity of children and adults with indoor fungal exposure such as toxic Stachybotrys chartarum. Indoor exposure was characterized using different methods including microscopic, culture, cytotoxicity screening tests, and chemical analyses. Clinical case histories and physical and laboratory findings are presented of children (age < 18 years, n = 22; mean age 9 years; 60% females) and adults (age >18 years, n = 125; mean age 39 years, 67% females) who consulted an environmental health specialty clinic. In the pediatric patients' exposure history, widespread fungal contamination of water-damaged building materials with known toxic or allergic fungi was identified. Primarily disorders of the respiratory system, skin, mucous membranes, and central nervous system were reported. Some enumeration and functional laboratory abnormalities, mainly of the lymphatic blood cells, were observed, although no statistically significant differences were found. IgE or IgG fungi-specific antibodies, used as exposure markers, were positive in less than 25% of all tested cases. In an evaluation of a symptomatic girl 11 years of age (sentinel case investigation) living in an apartment with verified toxigenic fungi (i.e., S. chartarum), several health indicators showed improvement after exposure cessation.

Evaluation and management of chronic work-related musculoskeletal disorders of the distal upper extremityThis clinical review will describe the epidemiology, clinical presentation, and management of the following work-related musculoskeletal disorders (WMSDs) of the distal upper extremity: deQuervain's disease, extensor and flexor forearm tendinitis/tendinosis, lateral and medial epicondylitis, cubital tunnel syndrome, and hand-arm vibration syndrome (HAVS). These conditions were selected for review either because they were among the most common WMSDs among patients attending the New York State Occupational Health Clinics (NYSOHC) network, or because there is strong evidence for work-relatedness in the clinical literature. Work-related carpal tunnel syndrome is discussed in an accompanying paper. In an attempt to provide evidence-based treatment recommendations, literature searches on the treatment of each condition were conducted via Medline for the years 1985-1999. There was a dearth of studies evaluating the efficacy of specific clinical treatments and ergonomic interventions for WMSDs. Therefore, many of the treatment recommendations presented here are based on a consensus of experienced public health-oriented occupational medicine physicians from the NYSOHC network after review of the pertinent literature. A summary table of the clinical features of the disorders is presented as a reference resource.

Lower socioeconomic status among men in relation to the association between job strain and blood pressureObjectives: This study attempted to determine whether the association between job strain (high job demands plus low job control) and blood pressure among men varies by socioeconomic status. Methods: The cross-sectional associations between job strain and ambulatory blood pressure, by level of education, occupational status, and income, and the interaction between job strain and these measures of socioeconomic status were assessed by multiple linear regression, adjusted for age, race or ethnicity, body mass index, alcohol use, smoking, standing position, and worksite for 283 men, aged 30-60 years, from eight worksites in New York City. Results: A substantial association between job strain and work ambulatory blood pressure was found among men with lower socioeconomic status, ranging from 2.7-11.8 mm Hg systolic to 1.9-6.1 mm Hg diastolic blood pressure, depending upon the measure of socioeconomic status examined. However, in the groups with high socioeconomic status, the association between job strain and ambulatory blood pressure at work was much smaller, the range in blood pressure being 0-5.3 (systolic) and 0.2-2.1 (diastolic) mm Hg. Two of the 10 tests of the interaction between job strain and socioeconomic status had a P-value of <0.05. Conclusions: These data provide evidence that the relationship between job strain and blood pressure is greater among men with lower socioeconomic status. PubMed Disclaimer

Is job strain a major source of cardiovascular disease risk?Empirical studies on job strain and cardiovascular disease (CVD), their internal validity, and the likely direction of biases were examined. The 17 longitudinal studies had the highest validity ratings. In all but two, biases towards the null dominated. Eight, including several of the largest, showed significant positive results; three had positive, nonsignificant findings. Six of nine case-control studies had significant positive findings; recall bias leading to overestimation appears to be fairly minimal. Four of eight cross-sectional studies had significant positive results. Men showed strong, consistent evidence of an association between exposure to job strain and CVD. The data of the women were more sparse and less consistent, but, as for the men, most of the studies probably underestimated existing effects. Other elements of causal inference, particularly biological plausibility, corroborated that job strain is a major CVD risk factor. Additional intervention studies are needed to examine the impact of ameliorating job strain upon CVD-related outcomes.

A gender approach to work ability and its relationship to professional and domestic work hours among nursing personnelThe association between working hours and work ability was examined in a cross-sectional study of male (N=156) and female (N=1092) nurses in three public hospitals. Working hours were considered in terms of their professional and domestic hours per week and their combined impact; total work load. Logistic regression analysis showed a significant association between total work load and inadequate work ability index (WAI) for females only. Females reported a higher proportion of inadequate WAI, fewer professional work hours but longer domestic work hours. There were no significant differences in total work load by gender. The combination of professional and domestic work hours in females seemed to best explain their lower work ability. The findings suggest that investigations into female well-being need to consider their total work load. Our male sample may have lacked sufficient power to detect a relationship between working hours and work ability.

Work conditions and masked (hidden) hypertension—insights into the global epidemic of hypertensionHypertension is the leading cause of cardiovascular disease. There is considerable evidence that work conditions play an important role in the etiology of essential hypertension. Ambulatory blood pressure during waking hours (work and home) is more strongly associated with subsequent cardiovascular disease than the traditional measurement of casual clinical blood pressure. A person with normal clinical blood pressure but elevated awake ambulatory blood pressure is said to have “masked” (or “occult” or “hidden”) hypertension. Masked hypertension is associated with increased cardiovascular risk, and has been observed in 10–30% of adults with normal clinical blood pressure. It has been hypothesized that exposure to workplace stressors first elevates work, but not clinical, blood pressure; after chronic exposure to stressors, both daytime and clinical pressure become elevated. In this manuscript, an algorithm is provided that targets ambulatory monitoring for high-risk groups and helps detect work-related hypertension. A public health approach incorporating clinical guidelines, workplace surveillance, and improved work conditions is recommended for tackling the epidemic of hypertension.
