Beese S, Postma J, Graves JM. Allostatic Load Measurement: A Systematic Review of Reviews, Database Inventory, and Considerations for Neighborhood Research. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph192417006. [PMID: 36554888 PMCID: PMC9779615 DOI: 10.3390/ijerph192417006] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 12/13/2022] [Accepted: 12/14/2022] [Indexed: 05/27/2023]
Abstract
BACKGROUND Neighborhoods are critical to understanding how environments influence health outcomes. Prolonged environmental stressors, such as a lack of green spaces and neighborhood socioeconomic disadvantage, have been associated with higher allostatic load levels. Since allostatic load levels experienced earlier in life have stronger associations with mortality risk, neighborhoods may be uniquely suited to monitor and mitigate the impacts of environmental stressors. Researchers often study allostatic load in neighborhoods by utilizing administrative boundaries within publicly accessible databases as proxies for neighborhoods. METHODS This systematic review of reviews aims to identify commonly used biomarkers in the measurement of allostatic load, compare measurement approaches, inventory databases to study allostatic load, and spotlight considerations referenced in the literature where allostatic load is studied in neighborhoods. The review was conducted using the search term "allostatic load" in the MEDLINE, CINAHL, and PsychINFO databases. The search results were filtered to include reviews. RESULTS The search returned 499 articles after deduplication. Overall, 18 synthesis reviews met the inclusion criteria and were retained for extraction. The synthesis reviews analyzed represented 238 studies published from 1995 to 2020. The original ten biomarkers were most often used to measure allostatic load. More recently, body mass index and C-reactive protein have additionally been frequently used to measure allostatic load burden. CONCLUSIONS The scientific contributions of this study are that we have identified a clear gap in geographic considerations when studying allostatic load. The implication of this study is that we have highlighted geographic concepts when conducting neighborhood-level research using administrative databases as a neighborhood proxy and outlined emerging future trends that can enable future study of allostatic load in the neighborhood context.

Abstract
Short sleep duration and poor sleep quality are associated with cardiovascular risk, and sympathetic nervous system (SNS) dysfunction appears to be a key contributor. The present review will characterize sympathetic function across several sleep disorders and insufficiencies in humans, including sleep deprivation, insomnia, narcolepsy, and obstructive sleep apnea (OSA). We will focus on direct assessments of sympathetic activation, e.g., plasma norepinephrine and muscle sympathetic nerve activity, but include heart rate variability (HRV) when direct assessments are lacking. The review also highlights sex as a key biological variable. Experimental models of total sleep deprivation and sleep restriction are converging to support several epidemiological studies reporting an association between short sleep duration and hypertension, especially in women. A systemic increase of SNS activity via plasma norepinephrine is present with insomnia and has also been confirmed with direct, regionally specific evidence from microneurographic studies. Narcolepsy is characterized by autonomic dysfunction via both HRV and microneurographic studies but with opposing conclusions regarding SNS activation. Robust sympathoexcitation is well documented in OSA and is related to baroreflex and chemoreflex dysfunction. Treatment of OSA with continuous positive airway pressure results in sympathoinhibition. In summary, sleep disorders and insufficiencies are often characterized by sympathoexcitation and/or sympathetic/baroreflex dysfunction, with several studies suggesting women may be at heightened risk.

Abstract
PURPOSE Frailty is an emerging global public health burden. Most existing studies have focused on risk factors for frailty, focusing less on protective factors against frailty. This study aims to examine the association between the sense of coherence (SOC), the most common construct of salutogenesis and frailty status among community-dwelling old adults. METHOD A cross-sectional study was conducted among 7,970 old adults aged ≥65 years in three cities in China from June 2019 to October 2020. Frailty was operationalised as the sum of self-reported fatigue, resistance, ambulation, illness, and loss of weight (FRAIL scale). The χ2 test was used to analyse the distribution difference of frailty in demographic, behavioural, and SOC levels. Confounder-adjusted multinomial logistic regression was used to examine the association between SOC and frailty. RESULTS The prevalence of pre-frailty and frailty was 43.1 and 8.0%, respectively. The results of the confounder-adjusted regression showed that older adults with moderate-level SOC (odds ratio, OR: 0.61, 95% CI: 0.54-0.69) and strong-level SOC (OR: 0.55, 0.48-0.64) had lower odds of being pre-frail compared to those with weak SOC. It also showed that older adults with moderate-level SOC (OR: 0.32, 95% CI: 0.27-0.40) and strong-level SOC (OR: 0.22, 95% CI: 0.16-0.29) had lower odds of being frail compared to those with weak SOC. CONCLUSION SOC may be a protective factor against frailty. Improving SOC may be a strategy to prevent frailty among Chinese community-dwelling older adults.

Abstract
INTRODUCTION Allostatic load refers to the cumulative burden of chronic stress and life events. It involves the interaction of different physiological systems at varying degrees of activity. When environmental challenges exceed the individual ability to cope, then allostatic overload ensues. Allostatic load is identified by the use of biomarkers and clinical criteria. OBJECTIVE To summarize the current knowledge on allostatic load and overload and its clinical implications based on a systematic review of the literature. METHODS PubMed, PsycINFO, Web of Science, and the Cochrane Library were searched from inception to December 2019. A manual search of the literature was also performed, and reference lists of the retrieved articles were examined.We considered only studies in which allostatic load or overload were adequately described and assessed in either clinical or non-clinical adult populations. RESULTS A total of 267 original investigations were included. They encompassed general population studies, as well as clinical studies on consequences of allostatic load/overload on both physical and mental health across a variety of settings. CONCLUSIONS The findings indicate that allostatic load and overload are associated with poorer health outcomes. Assessment of allostatic load provides support to the understanding of psychosocial determinants of health and lifestyle medicine. An integrated approach that includes both biological markers and clinimetric criteria is recommended.

Abstract
Allostatic load represents the 'wear and tear' of chronic stress on the brain and body that may differ between men and women. A small but growing number of studies are assessing allostatic load in relation to mental health. The objective of this systematic review was to (1) assess sex differences in allostatic load and (2) identify allostatic load associations that are specific to women. We systematically searched for allostatic load studies that included psychosocial causes and/or psychiatric consequences. Our search focused on allostatic load studies that disaggregated by sex and that include women. Sixty-two studies were included in this systematic review. First, men appear to have higher allostatic load than women. Second, women show gender-specific variation for numerous factors such as age, race/ethnicity, adversities, social support, and health behaviors that influence associations between allostatic load and mental health. Recommendations are made to guide researchers advance sex and gender approaches.

Abstract
OBJECTIVE Increasing evidence has shown an association between reduced psychological well-being and long-term morbidity. However, longitudinal studies addressing potential biobehavioral mechanisms, such as physiological function, are lacking. The aim of this study is to examine the association between changes in emotional vitality on levels and changes in allostatic load (AL), a measure of multisystem physiological dysregulation, as well as its composite risk markers. METHODS Participants comprised 5919 British civil servants from phases 3, 5, and 7 of the Whitehall II study. Psychological well-being was operationalized as emotional vitality. AL was measured using nine biomarkers of the cardiovascular, metabolic, and immune system. Linear mixed-effect models were used to determine the association between changes in emotional vitality between phases 3 and 5 and subsequent levels and change in AL from phases 5 to 7. Generalized linear models were used to address the association between changes in emotional vitality and individual risk markers. RESULTS Increase in emotional vitality was associated with a lower mean level of AL, whereas the AL slope was not markedly affected. Among the included risk markers, only interleukin-6 was weakly associated with changes in emotional vitality, with a 7% reduced risk of high levels of interleukin-6 per one-unit increase in emotional vitality. CONCLUSION This study found that an increase in emotional vitality was associated with subsequent lower levels, but not rate of change, of AL over time. Further research is needed to address the relationship between trajectories of psychological well-being and physiological dysregulation.

Abstract
In this selective review, emerging literature linking biological sex, sociocultural gender, and sexual orientation to stress hormone functioning and multisystemic physiological dysregulations are summarized. Beyond sex as a binary biological variable, continuums of sex hormones, gender roles, gender identity, and sexual orientation each uniquely help delineate pathways and mechanisms linked to stress-related disease trajectories. This implicates glucocorticoid functioning and allostatic load, the “wear and tear” of chronic stress in synergy with unhealthy behaviors. Clinical considerations are also discussed for the field of gender medicine.

Abstract
AIMS AND OBJECTIVES To elucidate the historical development of the allostatic load concept, alongside its use in nursing research, and to explore how allostatic load has been investigated among two stress-vulnerable populations. BACKGROUND 'Stress' is a prominent term in understanding the development of disease. Allostatic load is among several approaches undertaken to quantify the magnitude of stress and understand how stress can affect health. METHOD We explored the advent of allostatic load including its antecedents, and consequences. We used an exemplar case to apply the concept. We reviewed studies that used allostatic load among workers and women of childbearing age. RESULTS There remains a need to consolidate a common definition and operationalisation of allostatic load. Despite this need for further work, allostatic load is a good fit for nursing science which focuses on the client, environment and health. Only 12 studies explored allostatic load among workers (n = 6) and women of childbearing age (n = 6). In some studies, allostatic load was used as a predictor while in others it was used as an outcome. None of the studies considered it as a mediator. CONCLUSIONS The concept of allostatic load holds promise for nursing researchers to operationalise a holistic view of multiple stressors and to quantify their effects on health. Studies are needed to affirm the role of allostatic load as a potential mediator between multiple stressors and outcomes. Longitudinal studies are also needed to demonstrate a causal pathway from stressor exposure to tertiary outcomes such as chronic conditions and morbidity. RELEVANCE TO CLINICAL PRACTICE Allostatic load is a useful concept for nurses working with stress-vulnerable populations. With the use of an interpretable allostatic load index, nurses will be able to intervene at various stages of the allostasis-adaptation process (stress-response) and adjust interventions accordingly.

Abstract
OBJECTIVES Beyond male/female binaries, gender roles represent masculine and feminine traits that we assimilate and enact throughout life span development. Bem proposed that "androgynous" individuals adeptly adapt to different contexts by alternating from a strong repertoire of both masculine and feminine gender roles. By contrast, "undifferentiated" individuals may not adapt as well to social norms because of weak self-endorsed masculinity and femininity. METHODS Among 204 adults (mean [standard error] age = 40.4 [0.9] years; 70% women) working in a psychiatric hospital, we hypothesized that androgynous individuals would present better mental health and less physiological dysregulations known as allostatic load (AL) than undifferentiated individuals. AL was indexed using 20 biomarkers using the conventional "all-inclusive" formulation that ascribes cutoffs without regard for sex or an alternative "sex-specific" formulation with cutoffs tailored for each sex separately while controlling for sex hormones (testosterone, estradiol, progesterone). Well-validated questionnaires were used. RESULTS Independent of sex, androgynous individuals experienced higher self-esteem and well-being and lower depressive symptoms than did undifferentiated individuals. Men manifested higher AL than did women using the all-inclusive AL index (p = .044, ηP = 0.025). By contrast, the sex-specific AL algorithm unmasked a sex by gender roles interaction for AL (p = .043, ηP = 0.048): with the highest AL levels in undifferentiated men. Analysis using a gender index based on seven gendered constructs revealed that a greater propensity toward feminine characteristics correlated only with elevated sex-specific AL (r = 0.163, p = .025). CONCLUSIONS Beyond providing psychobiological evidence for Bem's theory, this study highlights how sex-specific AL formulations detect the effects of sociocultural gender.

Abstract
BACKGROUND Associations between the sense of humor and survival in relation to specific diseases has so far never been studied. METHODS We conducted a 15-year follow-up study of 53,556 participants in the population-based Nord-Trøndelag Health Study, Norway. Cognitive, social, and affective components of the sense of humor were obtained, and associations with all-cause mortality, mortality due to cardiovascular diseases (CVD), infections, cancer, and chronic obstructive pulmonary diseases were estimated by hazard ratios (HRs). RESULTS After multivariate adjustments, high scores on the cognitive component of the sense of humor were significantly associated with lower all-cause mortality in women (HR = 0.52, 95% confidence interval [CI] = 0.33-0.81), but not in men (HR = 0.88, 95% CI = 0.59-1.32). Mortality due to CVD was significantly lower in women with high scores on the cognitive component (HR = 0.27, 95% CI = 0.15-0.47), and so was mortality due to infections both in men (HR = 0.26, 95% CI = 0.09-0.74) and women (HR = 0.17, 95% CI = 0.04-0.76). The social and affective components of the sense of humor were not associated with mortality. In the total population, the positive association between the cognitive component of sense of humor and survival was present until the age of 85 years. CONCLUSIONS The cognitive component of the sense of humor is positively associated with survival from mortality related to CVD and infections in women and with infection-related mortality in men. The findings indicate that sense of humor is a health-protecting cognitive coping resource.

Abstract
Work stress is common and can lead to various bodily dysfunctions. The Allostatic Load Index (ALI) is a tool to measure the wear and tear of the body caused by chronic stress. This cross-sectional study aimed to explore the association of work-related stress and ALI in German industrial employees. A short form ALI should be developed for practical use of company physicians. In this exploration of an industrial cohort (n = 3797; 79.3% male), work stress was measured by the effort-reward imbalance (ERI) questionnaire in 2009-2011. ALI was calculated using 15 variables including anthropometric data, heart rate variability, as well as blood and urine samples based on predefined subclinical cut-off values. Differences in ALI related to low (≤1) and high (>1) ERI categories were tested. Logistic regression models estimated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the association between ALI and work stress controlling for multiple confounders. Employees exposed to high work stress showed higher ALI scores (p < 0.001) compared to those with low stress levels. In multivariable models, ALI was associated with work stress (OR 1.19 [95% CI: 1.00, 1.42]; p < 0.05) following adjustment for a range of potential confounders. By reducing ALI parameters to five variables this association increased modestly and remained statistically significant (OR 1.27 [95% CI: 1.05, 1.54]; p < 0.05). The results indicate that work stress is associated with ALI in German industrial employees. A short form index seems to be a promising approach for occupational health practitioners. The results should be validated in further longitudinal explorations defining a standard set of variables including gender-related thresholds.

Abstract
Background Little is known about the theoretically assumed association between adversity exposure over the life course and allostatic load in adulthood. Purpose This study aims to examine whether social and material adversity over the life course is related to allostatic load in mid-adulthood. Methods A 27-year prospective Swedish cohort (N = 822; 77% response rate) reported exposure to social and material adversities at age 16, 21, 30 and 43 years. At age 43, allostatic load was operationalized based on 12 biological parameters. Results Social adversity accumulated over the life course was related to allostatic load in both women and men, independently of cumulative socioeconomic disadvantage. Moreover, social adversity in adolescence (in women) and young adulthood (in men) was related to allostatic load, independently of cumulative socioeconomic disadvantage and also of later adversity exposure during adulthood. Conclusion Exposure to adversities involving relational threats impacts on allostatic load in adulthood and operates according to life course models of cumulative risk and a sensitive period around the transition into adulthood.

Data from 994 adults who participated in both the Health 2000 survey and the Follow-Up Study of Finnish Adults' Oral Health were analysed for this study. At baseline, participants provided information on demographic characteristics, education level, the SOC scale and dental behaviours (tooth brushing frequency, dental attendance and sugar intake frequency). The 4-year incidence of tooth decay was calculated using data from baseline and follow-up clinical oral examinations. Baseline SOC was significantly related to 4-year incidence of tooth decay after adjustment for demographic factors and education (relative risk: 0.79, 95% CI: 0.63-0.98). This effect was fully attenuated after further adjustment for the three dental behaviours. Tooth brushing frequency and dental attendance were the only dental behaviours significantly related to incidence of tooth decay. This prospective study suggests that SOC predicts incidence of tooth decay and that dental behaviours may help explaining why adults with strong SOC have lower risk of developing tooth decay than those with weak SOC.

Abstract
Job insecurity has been linked to different negative outcomes, such as negative work attitudes and health problems, with most studies including self-reported outcomes. Extending earlier research, the present study includes both self-reported and physiological indicators of health and sets out to investigate whether higher levels of job insecurity are related to higher levels of allostatic load, higher levels of morning cortisol, more physician-diagnosed symptoms of ill-health and poorer self-rated health. The study also investigated whether self-rated health mediated the relation between job insecurity and physiological outcomes. This was cross-sectionally studied in a cohort of Swedish women who participated in a large-scale longitudinal study focusing on life span development and adaptation. The results showed that job insecurity was related to self-rated health and morning cortisol, and, contrary to expectations, that job insecurity was unrelated to allostatic load and physician ratings, both directly and indirectly. The results indicate that, in healthy working women, job insecurity may be less detrimental to long-term physiological health than originally hypothesized.

Abstract
AbstractThe allostatic load (AL) model represents an interdisciplinary approach to comprehensively conceptualize and quantify chronic stress in relation to pathologies throughout the life cycle. This article first reviews the AL model, followed by interactions among early adversity, genetics, environmental toxins, as well as distinctions among sex, gender, and sex hormones as integral antecedents of AL. We next explore perspectives on severe mental illness, dementia, and caregiving as unique human models of AL that merit future investigations in the field of developmental psychopathology. A complimenting transdisciplinary perspective is applied throughout, whereby we argue that the AL model goes beyond traditional stress–disease theories toward the advancement of person-centered research and practice that promote not only physical health but also mental health.

Abstract
OBJECTIVE To prospectively explore the significance of sense of humor for survival over 7 years in an adult county population. METHODS Residents in the county of Nord-Trøndelag, Norway, aged 20 and older, were invited to take part in a public health survey during 1995-97 (HUNT-2), and 66,140 (71.2 %) participated. Sense of humor was estimated by responses to a cognitive (N = 53,546), social (N = 52,198), and affective (N = 53,132) item, respectively, taken from the Sense of Humor Questionnaire (SHQ). Sum scores were tested by Cox survival regression analyses applied to gender, age, and subjective health. RESULTS Hazard ratios were reduced with sense of humor (continuous scale: HR = 0.73; high versus low by median split: HR = 0.50) as contrasted with increase of HR with a number of classical risk factors (e.g., cardiovascular disease: HR = 6.28; diabetes: HR = 4.86; cancer: HR = 4.18; poor subjective health: HR = 2.89). Gender proved to be of trivial importance to the effect of sense of humor in survival. Subjective health correlated positively with sense of humor and therefore might have presented a spurious relation of survival with humor, but sense of humor proved to reduce HR both in individuals with poor and good subjective health. However, above age 65 the effect of sense of humor on survival became less evident. CONCLUSION Sense of humor appeared to increase the probability of survival into retirement, and this effect appeared independent of subjective health. Age under 65 mediated this effect, whereas it disappeared beyond this age.

Abstract
OBJECTIVES This study was designed to investigate how the interaction between the ability of medical residents (doctors in postgraduate training) to cope with stress and their working conditions might affect their level of job-related stress. METHODS A self-administered questionnaire was distributed to 549 first-year medical residents at 38 postgraduate education hospitals in Japan, 1-2 months after the start of clinical training. The questionnaires contained the 29-item Sense of Coherence (SOC) Scale, the Brief Scales for Job Stress (BSJS), the 12-item General Health Questionnaire (GHQ-12) and questions on basic conditions such as working hours. Sense of coherence is an important concept from the viewpoint of salutogenesis theory and influences stress recognition style. People with a strong SOC have a high ability to cope with stress. RESULTS The mean +/- standard deviation (SD) score on the SOC Scale was 134.5 +/- 20.5. All participants were classified into three groups according to their SOC Scale scores. Although the objective working conditions of the three groups were statistically similar, the group with the weakest SOC Scale score showed poorer mental health status (p < 0.05) and scored lower for 'reward from work' compared with the groups with stronger SOC scores (p < 0.05). The weaker SOC group also scored higher for 'mental workload' and 'problems in personal relationships' than the other two groups (p < 0.05). Moreover, the weak SOC group scored less for 'support from colleagues and superiors' than the strong SOC group (p < 0.05). A stepwise multiple regression analysis for GHQ-12 score was conducted (R(2) = 0.45). 'Sleep time', 'workload', 'mental workload' and 'problems in personal relationships' were positively correlated with GHQ-12 scores. 'Reward from work' was negatively correlated with GHQ-12 scores. CONCLUSIONS Residents' mental health was associated not only with working conditions, but also with their attitudes towards those working conditions. Enhancing residents' sense of 'reward from work' might be important in reducing their reactions to stress.

Abstract
Via a large scale cross-sectional study among Japanese white color workers, the authors aimed to elucidate: (1) the distributions of Sense of Coherence (SOC), which reflect stress coping abilities, (2) the distributions of the Brief Scale for Coping Profile (BSCP) which reflect coping profiles for stressors; (3) and the association between SOC and BSCP. Anonymous self-administered questionnaires were sent to 20,742 employees at educational and research institutions in Tsukuba Research Park City. A total of 12,009 (57.9%) workers completed and returned the questionnaire; 10,317 workers without missing data were analyzed. SOC scale scores and BSCP subscale scores differed by gender, age, and other demographic features. Among the BSCP subscales, workers whose SOC scale scores were higher tended to adopt a problem-focused coping profile, whereas workers whose SOC scale scores were lower adopted an emotion-focused coping profile. The coping profile that workers adopted depended on their background and demographic characteristics. Stronger SOC allowed one to adopt a problem-focused coping profile that allows for better coping with work-related stressors.

Abstract
The relation between religion and (or) spirituality (RS), and mental health has shown generally positive associations; however, it is a complex and often emotion-laden field of study. We attempt to examine potential mechanisms that have been proposed as mediators for the RS and mental health relation. We also examine more philosophical areas including patient and physician opinions about inclusion of RS in patient care, and ethical issues that may arise. We review suggested guidelines for sensitive patient inquiry, and opportunities and challenges for education of psychiatrists and trainees. We also study practical ways to incorporate psychospiritual interventions into patient treatment, with specific reference to more common spiritual issues such as forgiveness, gratitude, and altruism.

Abstract
This study set out to investigate how biological dysregulation, in terms of allostatic load (AL), relates to self-rated health (SRH) in women. Data on SRH and 12 biomarkers used to assess AL were available for 241 employees from the health care sector and 98 employees from the IT/media sector. In line with the hypothesis, results showed that a poor SRH, along with occupational sector, age and education, were significantly associated with a high AL, particularly for those working within the health care sector. This association between a poor SRH and AL, suggests a link between SRH and biological dysregulation.

Abstract
Epidemiological studies have shown that chronic work stress or unfavourable psychosocial work conditions are prospectively associated with different adverse health outcomes. The aim of the present cross-sectional study was to investigate the relationship between work-related chronic stress as well as exhaustion and a cumulative measure of physiological wear-and-tear called allostastic load (AL). AL could be a possible biological pathway for how chronic work stress and exhaustion lead to health impairments in the long run. As the teaching profession has been proposed to be a potentially high stressful occupation, chronic work stress (effort-reward-imbalance) and exhaustion were assessed in 104 female school teachers. AL was first analyzed according to McEwen's classical model comprised of ten parameters including cortisol, epinephrine and norepinephrine, dehydroepiandrosterone-sulphate (DHEA-S), waist/hip-ratio (WHR), glycosylated haemoglobin (HbA1c), high-density lipoprotein (HDL), total cholesterol/HDL-ratio, and systolic and diastolic blood pressure. Additionally it was extended to include tumor-necrosis-factor-alpha (TNF-alpha), C-reactive protein (CRP), fibrinogen, D-dimer, percent-body-fat, triglycerides, and glucose levels. A substantial proportion of our sample was highly exhausted whereas relatively few teachers showed high effort-reward-imbalance. AL scores were significantly higher in women high on effort-reward-imbalance or suffering from exhaustion. Although all teachers had been in a good health status, chronic work stress as well as exhaustion appears to be associated with changes in a multi-system summary indicator of physiological risk.
