Project description:ObjectivesWe aimed to prospectively study the association between normalised difference vegetation index (NDVI) as a measure of greenness around homes and occupational stress.SettingA population-based cohort in Munich and Dresden cities was followed from age 16-18 years to age 20-23 years (n=1632).ParticipantsAt baseline, all participants attended high-school while at follow-up some had started working and others studying at university. At baseline and in each follow-up, we assigned NDVI based on participants' residential geocoded addresses and categorised it by quartiles.Outcome measuresSchool-related, university-related or job-related self-reported chronic stress was assessed at the two follow-ups by the Trier Scale for Assessment of Chronic Stress using work discontent and work overload as outcomes. We modelled the association employing ordinal generalised estimating equations model accounting for changes in sociodemographics, non-job-related stress, job history and environmental covariates. Stratified analysis by each city was performed.ResultsNVDI at baseline was higher for participants from Dresden (median=0.36; IQR 0.31-0.41) than Munich (0.31; 0.26-0.34). At follow-up, it decreased only for participants in Dresden (0.34; 0.30-0.40). Higher greenness (quartile 4 vs quartile 1) was associated with less work discontent (OR 0.89; 95% CI 0.80 to 0.99) and less work overload (OR 0.87; 95% CI 0.78 to 0.96). In stratified analyses, results were more consistent for Munich than for Dresden.ConclusionsOur results suggest that residential green spaces, using the vegetation index as a proxy for exposure, are inversely associated with two types of job-related chronic stress in German young adults transitioning from school to university or working life.

Project description:Background Acute psychological stress and negative emotions are known risk factors for atrial fibrillation (AF). Whether exposure to chronic stress syndromes, such as posttraumatic stress disorder (PTSD), also increases susceptibility to AF is unknown. Methods and Results We prospectively assessed the incidence of AF over a 13-year period among 988 090 young and middle-aged veterans (mean age, 30.29±9.19 years; 87.8% men, 64.5% white) who first accessed care through the Veterans Health Administration from October 2001 to November 2014 and were free of AF, atrial flutter, or atrial tachycardia at baseline. Time-varying, multivariate Cox proportional hazard models were used to examine the independent contribution of PTSD to new AF. We also tested for effect modification by sex and controlled for healthcare use. During a mean follow-up of 4.8 years, 2491 patients were diagnosed with AF. Patients with PTSD had a higher overall incidence of AF (P<0.0001) and were more likely to develop AF at a younger age than those without PTSD (P=0.004). PTSD was significantly associated with incident AF in unadjusted models (hazard ratio, 1.31; 95% CI, 1.19-1.43) and models that adjusted for demographics, lifestyle factors, cardiovascular risk factors, and depression (hazard ratio, 1.13; 95% CI, 1.02-1.24). The interaction with sex was nonsignificant (P=0.93). Conclusions PTSD was associated increased risk for early incident AF after adjustment for established AF risk factors and depression in this cohort of young and middle-aged veterans. Findings from this study require validation in more diverse populations to determine their generalizability.

Project description:ObjectiveTo determine the frequency of disability in young people and adults admitted to hospital with a head injury and to estimate the annual incidence in the community.DesignProspective, hospital based cohort study, with one year follow up of sample stratified by coma score.SettingFive acute hospitals in Glasgow.Subjects2962 patients (aged 14 years or more) with head injury; 549 (71%) of the 769 patients selected for follow up participated.Main outcome measuresGlasgow outcome scale and problem orientated questionnaire.ResultsSurvival with moderate or severe disability was common after mild head injury (47%, 95% confidence interval 42% to 52%) and similar to that after moderate (45%, 35% to 56%) or severe injury (48%, 36% to 60%). By extrapolation from the population identified (90% of whom had mild injuries), it was estimated that annually in Glasgow (population 909 498) 1400 young people and adults are still disabled one year after head injury.ConclusionThe incidence of disability in young people and adults admitted with a head injury is higher than expected. This reflects the high rate of sequelae previously unrecognised in the large number of patients admitted to hospital with an apparently mild head injury.

Project description:Background: We seek to understand correlates of chronic stress and their influence on the development of substance use in a population-based cohort of young adults (OYSUP). Methodology: We evaluated clinical features, salivary RNA metrics and differential expression of candidate genes in unfractionated saliva samples from 48 individuals (31% female, 55% ever-smoking) randomly selected from two groups stratified by high versus low severe negative life events and difficulties within the last year as as measured by the Life Events and Difficulties Schedule (LEDS, Brown & Harris, 1978). We used multiple analytical platforms, multiple reference genes and 18 replicates of all gene expression assays (assays). We chose 38 candidate genes previously identified as differentially expressed in a genome-wide scan of monocyte RNA in 11 familial caregivers of glioblastoma multiforme patients and 10 control subjects matched on age (middle-aged), gender (57% female), ethnicity and marital status and free of major stressors during the previous year. Principal Findings: We observed significant differences in smoking prevalence (Pearson’s χ22d.f.=4.5, P=0.035) and RNA integrity score (t=2.12, P=0.039) between stress strata. We analyzed quantitative PCR data using both the comparative standard curve (CSC) and relative standard curve (RSC) methods because 34% of assays had efficiency estimates <90%. Assay data exhibited excellent linearity and low variability. We observed significant under expression of five assays in the high stress stratum using both methods, four of which interrogate glucocorticoid receptor regulated genes. Post-hoc analyses identified significant associations of RNA yield, integrity score, gender, ever-smoking and/or stress with results of normalized gene expression in 22/37 assays. IL8 expression remained significantly associated with chronic stress after adjustment for clinical and salivary RNA variables. Salivary IL8 expression has been previously associated with oropharyngeal squamous cell cancer. Conclusions: A gene expression signature of chronic stress previously observed in adult hematopoietic samples is observed in the unfractionated saliva of young adults. Future investigation will need to analyze associated clinical, metabolic, meta-genomic, and proteomic components of unfractionated saliva to elucidate factors influencing the salivary transcriptome.

Gene expression was performed on a Fluidigm 48 x 48 array on 48 individuals for 38 target genes and 6 possible reference genes (represented by 9 reference assays) in triplicate. Quantitative Q-PCR datas were normalized according to relative levels of four reference genes (CDKN1B, YWHAZ, RPL13A, and UBC).

Project description:The substantial increase in the prevalence of non-communicable diseases in Indonesia might be driven by rapid socio-economic development through urbanization. Here, we carried out a longitudinal 1-year follow-up study to evaluate the effect of urbanization, an important determinant of health, on metabolic profiles of young Indonesian adults. University freshmen/women in Jakarta, aged 16-25 years, who either had recently migrated from rural areas or originated from urban settings were studied. Anthropometry, dietary intake, and physical activity, as well as fasting blood glucose and insulin, leptin, and adiponectin were measured at baseline and repeated at one year follow-up. At baseline, 106 urban and 83 rural subjects were recruited, of which 81 urban and 66 rural were followed up. At baseline, rural subjects had better adiposity profiles, whole-body insulin resistance, and adipokine levels compared to their urban counterparts. After 1-year, rural subjects experienced an almost twice higher increase in BMI than urban subjects (estimate (95%CI): 1.23 (0.94; 1.52) and 0.69 (0.43; 0.95) for rural and urban subjects, respectively, Pint < 0.01). Fat intake served as the major dietary component, which partially mediates the differences in BMI between urban and rural group at baseline. It also contributed to the changes in BMI over time for both groups, although it does not explain the enhanced gain of BMI in rural subjects. A significantly higher increase of leptin/adiponectin ratio was also seen in rural subjects after 1-year of living in an urban area. In conclusion, urbanization was associated with less favorable changes in adiposity and adipokine profiles in a population of young Indonesian adults.

Project description:ObjectiveTo determine adolescent predictors of muscularity-oriented disordered eating behaviors in young men and women using a nationally representative longitudinal sample in the United States and to examine differences by sex.MethodWe used nationally representative longitudinal cohort data collected from baseline (11-18 years old, 1994-1995) and 7-year follow-up (18-24 years old, 2001-2002) of the National Longitudinal Study of Adolescent to Adult Health. We examined adolescent demographic, behavioral, and mental health predictors of young adult muscularity-oriented disordered eating behaviors defined as eating more or differently to gain weight or bulk up, supplements to gain weight or bulk up, or androgenic anabolic steroid use at 7-year follow-up.ResultsOf the 14,891 included participants, 22% of males and 5% of females reported any muscularity-oriented disordered eating behavior at follow-up in young adulthood. Factors recorded at adolescence that were prospectively associated with higher odds of muscularity-oriented disordered eating in both sexes included black race, exercising to gain weight, self-perception of being underweight, and lower body mass index z-score. In addition, participation in weightlifting; roller-blading, roller-skating, skate-boarding, or bicycling; and alcohol among males and depressive symptoms among females during adolescence were associated with higher odds of muscularity-oriented disordered eating in young adulthood.ConclusionsInterventions to prevent muscularity-oriented disordered eating behaviors may target at-risk youth, particularly those of black race or who engage in exercise to gain weight. Future research should examine longitudinal health outcomes associated with muscularity-oriented disordered eating behaviors.

Project description:Among the well-known physiological consequences of early adverse environments is dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. A number of studies demonstrate that negative parenting and living with parents with a history of substance abuse and mental health problems may be associated with HPA axis dysregulation in children. In contrast, studies of more delayed effects in adult offspring, especially prospective, are still scarce. This study was a prospective longitudinal investigation of the association between maternal mental illnesses/substance abuse and maternal negative parenting/parental stress on one side and, on the other side, adult offspring outcomes 10 years later-specifically, we studied the activity of offspring's neuroendocrine (cortisol) and autonomic (heart rate) systems when exposed to a mild psychological stressor. Children of mothers with mental illnesses and/or substance abuse were exposed to more disadvantaged conditions (higher negative parenting and community violence). Despite this, maternal risk groups (having a mother with mental illnesses and/or substance abuse) were not associated with any of the indicators of stress systems activity. Regardless of the risk group, participants with dysregulated HPA axis activity experienced a higher level of negative parenting. Altogether, our study provides evidence that negative parenting may have long-lasting effects on stress-sensitive physiological mechanisms.

Project description:BackgroundAdolescents and early young adults (AYAs) with cancer are at high risk for poor outcomes. Positive psychological responses such as benefit-finding may buffer the negative impacts of cancer but are poorly understood in this population.ObjectiveWe aimed to prospectively describe the content and trajectory of benefit- and burden-finding among AYAs to develop potential targets for future intervention.Patients and methodsOne-on-one semistructured interviews were conducted with English-speaking AYA patients (aged 14-25 years) within 60 days of diagnosis of a noncentral nervous system malignancy requiring chemotherapy, 6-12 and 12-18 months later. Interviews were coded using directed content analyses with a priori schema defined by existing theoretical frameworks, including changed sense of self, relationships, philosophy of life, and physical well-being. We compared the content, raw counts, and ratios of benefit-to-burden by patient and by time point.Setting/subjectsSeventeen participants at one tertiary academic medical center (mean age 17.1 years, SD = 2.7) with sarcoma (n = 8), acute leukemia (n = 6), and lymphoma (n = 3) completed 44 interviews with >100 hours of transcript-data.ResultsAverage benefit counts were higher than average burden counts at each time point; 68% of interviews had a benefit-to-burden ratio >1. Positive changed sense-of-self was the most common benefit across all time points (44% of all reported benefits); reports of physical distress were the most common burden (32%). Longitudinal analyses suggested perceptions evolved; participants tended to focus less on physical manifestations and more on personal strengths and life purpose.ConclusionsAYAs with cancer identify more benefits than burdens throughout cancer treatment and demonstrate rapid maturation of perspectives. These findings not only inform communication practices with AYAs but also suggest opportunities for interventions to potentially improve outcomes.
