Self-perceived physical health predicts cardiovascular disease incidence and death among postmenopausal women

Association of perceived mental health with mortality, and analysis of potential pathways in Italian men and women: Prospective results from the Moli-sani Study cohort

BACKGROUND

Perceived mental health (PMH) was reportedly associated with mortality in general populations worldwide. However, little is known about sex differences and pathways potentially linking PMH to mortality. We explored the relationship between PMH and mortality in Italian men and women, and analysed potential explanatory factors.

METHODS

We performed longitudinal analyses on 9045 men and 9467 women (population mean age 53.8 ± 11.2 years) from the Moli-sani Study. Baseline PMH was assessed through a self-administered Short Form 36-item questionnaire. Cox proportional hazard regression was used to estimate hazard ratios (HRs) and 95 % confidence intervals (95%CI) of death across sex-specific quartiles of PMH, controlling for age, chronic health conditions, and perceived physical health. Socioeconomic, behavioural, and physiological factors were examined as potential explanatory factors of the association between PMH and mortality.

RESULTS

In women, HRs for the highest (Q4) vs. bottom quartile (Q1) of PMH were 0.75 (95%CI 0.60-0.96) for all-cause mortality and 0.59 (0.40-0.88) for cardiovascular mortality. Part of these associations (25.8 % and 15.7 %, for all-cause and cardiovascular mortality, respectively) was explained by physiological factors. In men, higher PMH was associated with higher survival (HR = 0.82; 0.69-0.98, for Q4 vs. Q1) and reduced hazard of other cause mortality (HR = 0.67; 0.48-0.95). More than half of the association with all-cause mortality was explained by physiological factors.

LIMITATIONS

PMH was measured at baseline only.

CONCLUSIONS

PMH was independently associated with mortality in men and women. Public health policies aimed at reducing the burden of chronic diseases should prioritize perceived mental health assessment along with other interventions.

Health-Related Quality of Life Scores and Values as Predictors of Mortality: A Scoping Review

Health-related quality of life (HRQoL) can be assessed through measures that can be generic or disease specific, encompass several independent scales, or employ holistic assessment (i.e., the derivation of composite scores). HRQoL measures may identify patients with differential risk profiles. However, the usefulness of generic and holistic HRQoL measures in identifying patients at higher risk of death is unclear. The aim of the present study was to undertake a scoping review of generic, holistic assessments of HRQoL as predictors of mortality in general non-patient populations and clinical sub-populations with specified conditions or risk factors in persons 18 years or older. Five databases were searched from 18 June to 29 June 2020 to identify peer-reviewed published articles. The searches were updated in August 2022. Reference lists of included and cited articles were also searched. Of 2552 articles screened, 110 met criteria for inclusion. Over one-third of studies were from North America. Most studies pertained to sub-populations with specified conditions and/or risk factors, almost a quarter for people with cardiovascular diseases. There were no studies pertaining to people with mental health conditions. Nearly three-quarters of the studies used a RAND Corporation QoL instrument, predominantly the SF-36, and nearly a quarter, a utility instrument, predominantly the EQ-5D. HRQoL was associated with mortality in 67 of 72 univariate analyses (92%) and 100 of 109 multivariate analyses (92%). HRQoL was found to be associated with mortality in the general population and clinical sub-populations with physical health conditions. Whether this relationship holds in people with mental health conditions is not known. HRQoL assessment may be useful for screening and/or monitoring purposes to understand how people perceive their health and well-being and as an indicator of mortality risk, encouraging better-quality and timely patient care to support and maximize what may be a patient's only modifiable outcome.

Associations of Health-Related Quality of Life and Sleep Disturbance With Cardiovascular Disease Risk in Postmenopausal Breast Cancer Survivors

BACKGROUND

Breast cancer (BC) survivors are at an increased risk of long-term cardiovascular disease (CVD), often attributed to cancer treatment. However, cancer treatment may also negatively impact health-related quality of life (HRQoL), a risk factor of CVD in the general population.

OBJECTIVE

We examined whether sleep disturbance, and physical or mental HRQoL were associated with CVD risk in BC survivors.

METHODS

We conducted a longitudinal analysis in the Women's Health Initiative of postmenopausal women given a diagnosis of invasive BC during follow-up through 2010 with no history of CVD before BC. The primary outcome was incident CVD, defined as physician-adjudicated coronary heart disease or stroke, after BC. Physical and mental HRQoL, measured by the Short-Form 36 Physical and Mental Component Summary scores, and sleep disturbance, measured by the Women's Health Initiative Insomnia Rating Scale, were recorded post BC. Time-dependent Cox proportional hazards models were used starting at BC diagnosis until 2010 or censoring and adjusted for relevant confounders.

RESULTS

In 2884 BC survivors, 157 developed CVD during a median follow-up of 9.5 years. After adjustment, higher Physical Component Summary scores were significantly associated with a lower risk of CVD (hazard ratio, 0.90 [95% confidence interval, 0.81-0.99]; per 5-point increment in Physical Component Summary). No associations with CVD were found for Mental Component Summary or Insomnia Rating Scale.

CONCLUSION

In BC survivors, poor physical HRQoL is a significant predictor of CVD.

IMPLICATIONS FOR PRACTICE

Our findings highlight the importance for nurses to assess and promote physical HRQoL as part of a holistic approach to mitigating the risk of CVD in BC survivors.

Pre- and Early Peri-menopausal Physical Function and Risk of Cardiovascular Events: The Study of Women's Health Across the Nation

OBJECTIVES

To determine whether physical function (PF) before menopause is related to cardiovascular disease (CVD) risk.

METHODS

Participants were N = 2950 pre-/early peri-menopausal women (median age 46, (25th-75th percentile: 43-48 years). Physical function was assessed at baseline using the Physical Function subscale of the SF-36 and scores were trichotomized (no, some, or substantial limitations). Clinical CVD events were ascertained at annual/biennial clinical assessments through the 15th follow-up visit. Risk of CVD was determined with Cox proportional hazards models. Results: Women were followed for a median of 19.1 years, during which 220 women had a CVD event. In fully adjusted models, women with substantial limitations at baseline had higher CVD risk compared to women with no limitations (hazards ratio [HR] = 1.55, 95% confidence interval [CI]: 1.12-2.33). Discussion: Substantial PF limitations in pre- and early peri-menopausal women are associated with higher risk of clinical CVD events, consistent with literature in older adults.

Lifetime pathogen burden, inflammatory markers, and depression in community-dwelling older adults

The link between pathogen exposure and mental health has long been hypothesized, but evidence remains limited. We investigated the association of seropositivity to common pathogens and total pathogen burden with depression and mental health and explored the role of mediating inflammatory cytokines. We profiled in 884 participants in the Singapore Longitudinal Ageing Studies, mean (SD) age: 67.9 (8.1) years, their seropositivities for 11 pathogens (CMV, HSV 1, HSV 2, HHV-6, EBV, VZV, RSV, Dengue, Chikungunya, H. Pylori and Plasmodium) and pathogen burden, Geriatric Depression Scale (GDS) score at baseline and 3-4 and 6-8 years follow-up, and baseline Mental Component Score (MCS) of 12-Item Short Form Survey (SF-12). Inflammatory markers included CRP, TNF-α, IL-6, MIP-1α, sgp130, sTNF-RI, sTNF-RII, C3a, and MCP-2. Controlling for age, sex, ethnicity, education, marital status, living alone, and smoking status, high pathogen burden (7 + cumulative infections) compared to low pathogen burden (1-5 cumulative infections) was significantly associated with period prevalence (the highest GDS score from baseline and follow-up measurements) of depressive symptoms (OR = 2.36, 95% CI = 1.05-5.33) and impaired mental health (OR = 2.25, 95% CI = 1.18-4.30). CMV seropositivity and HSV1 seropositivity, which are highly prevalent and most widely studied, were associated with estimated 2-fold increased odds of depression, but only HSV1 seropositivity was significantly associated with depression after adjusting for confounders. Notably, adjusted for confounders, RSV, H. pylori and Plasmodium seropositivity were significantly associated with increased odds, and Dengue seropositivity was associated with unexpectedly deceased odds of depressive symptoms and impaired mental health. The association of pathogen exposure with depression and mental health were at least in parts explained by inflammatory markers. Adding certain inflammatory markers to the models attenuated or weakened the association. Bootstrap method showed that MIP-1α significantly mediated the association between pathogen burden and mental health. In conclusion, lifelong pathogen burden and specific infections are associated with depression and impaired mental health in older adults.

The Association of Neighborhood Changes with Health-Related Quality of Life in the Women's Health Initiative

Longitudinal studies can help us understand the effects of long-term neighborhood changes, as these can capture individual self-appraisal of current and future circumstances. We analyzed the association between neighborhood changes and health-related quality of life (HRQoL) outcomes among older women from the Women's Health Initiative (WHI) study. We used a subset (n = 49,254) of the longitudinal WHI dataset of female participants, aged 50-79 at baseline, recruited from 40 clinical centers across the U.S. beginning in 1993. Two HRQoL outcomes were explored: self-rated quality of life (SRQoL), and physical functioning-related quality of life (PFQoL). We used U.S. census tract-level changes in median household income between the 2000 census and 2007-2011 American Community Survey to classify neighborhoods as "upgrading," "declining," or "stable." Multi-level models were used to identify significant associations between neighborhood change and HRQoL outcomes over time. Compared to participants residing in upgrading neighborhoods, participants in stable and declining neighborhoods reported significantly lower PFQoL. A significant interaction was observed with income such that the effect of neighborhood change was greater at lower levels of income.

Physical function trends and their association with mortality in postmenopausal women

OBJECTIVE

Research is limited regarding the predictive utility of the RAND-36 questionnaire and physical performance tests in relation to all-cause, cardiovascular disease (CVD), and total-cancer mortality in older women.

METHODS

Data on the RAND-36 questionnaire, gait speed, and chair stand performance were assessed in 5,534 women aged ≥ 65 years at baseline. A subset (n = 298) had physical function assessments additionally at follow-up (years 1, 3, or 6). Multivariable Cox proportional hazards regression models estimated associations (HR) for a 1-standard deviation (SD) difference in baseline RAND-36 scores and performance tests (alone and combined) with mortality outcomes in the overall cohort and in models stratified by enrollment age (<70 and ≥70 y). The relative prognostic value of each physical function exposure was assessed using the Uno concordance statistic.

RESULTS

A total of 1,186 deaths from any cause, 402 deaths from CVD, and 382 deaths from total-cancer were identified during a mean follow-up of 12.6 years. Overall, each 1-SD unit higher baseline RAND-36 score was associated with significantly lower all-cause mortality (HR =0.90) and discriminatory capacity (Uno=0.65) that was comparable to each performance exposure (HRs 0.88-0.91; Uno = 0.65). These findings were consistent in women aged <70 and ≥70 years. The associations of RAND-36 and performance measures with CVD mortality and total-cancer mortality were not significant in multivariable models nor in age-stratified models.

CONCLUSIONS

The RAND-36 questionnaire is a reasonable substitute for tracking physical functioning and estimating its association with all-cause mortality in older adults when clinical performance testing is not feasible.

Health-related biological and non-biological consequences of forgoing healthcare for economic reasons

Forgoing healthcare for economic reasons has been previously associated with adverse health outcomes, including a higher risk of hospitalization, a lower quality of life, and worse self-reported health. However, the exact cause-to-effect relation between forgoing healthcare and health-related outcomes has been insufficiently described. Here, we investigate the prospective health consequences of forgoing healthcare for economic reasons using data from “ReBus” (N = 400), a prospective study examining the health consequences of forgoing healthcare (Baseline: 2008–2013, Follow-up: 2014–2016). Using regression models, we explored the baseline determinants of forgoing healthcare, including socioeconomic, demographic, and pre-existing health-risk factors, and examined the associations between forgoing healthcare at baseline and health deterioration at follow-up, using highly pertinent biomarkers (glucose, glycated hemoglobin, lipids, blood pressure) and SF-36 questionnaire data.

Low income, low occupation, low education, and smoking were associated with higher odds of forgoing healthcare at baseline. Forgoing healthcare for economic reasons at baseline was subsequently related to detrimental changes in glucose, high-density lipoprotein cholesterol (HDL), and blood pressure (BP) at follow-up, independently of baseline socioeconomic factors (Glucose-β = 0.19, 95%CI[0.03;0.34], HDL-β = -0.07, 95%CI[-0.14;0.01], BP-β = 3.30, 95%CI[-0.01;6.60]). Moreover, we found strong associations between forgoing healthcare and adverse SF-36 health scores at follow-up, with individuals forgoing healthcare systematically displaying worse health scores (6%–11% lower scores).

For the first time, we show that forgoing healthcare for economic reasons predicts adverse health-related consequences 2–8 years later. Our findings shall further encourage the implementation of public health measures aimed at identifying individuals who forgo healthcare and preventing the adverse health consequences of unmet medical needs.

Cardiovascular risk and functional burden at midlife: Prospective associations of isotemporal reallocations of accelerometer-measured physical activity and sedentary time in the CARDIA study

Cardiovascular risk and functional burden, or the accumulation of cardiovascular risk factors coupled with functional decline, may be an important risk state analogy to multimorbidity. We investigated prospective associations of sedentary time (ST), light intensity physical activity (LPA), and moderate to vigorous intensity physical activity (MVPA) with cardiovascular risk and functional burden at midlife. Participants were 1648 adults (mean ± SD age = 45 ± 4 years, 61% female, 39% Black) from Coronary Artery Risk Development in Young Adults (CARDIA) who wore accelerometers in 2005-2006 and 2015-2016. Cardiovascular risk and functional burden was defined as ≥2 cardiovascular risk factors (untreated/uncontrolled hypertension and hypercholesterolemia, type 2 diabetes, reduced kidney function) and/or functional decline conditions (reduced physical functioning and depressive symptoms). Prospective logistic regression models tested single activity, partition, and isotemporal substitution associations of accelerometer-measured ST, LPA, and MVPA with cardiovascular risk and functional burden 10 years later. In isotemporal models of baseline activity, reallocating 24 min of ST to MVPA was associated with 15% lower odds of cardiovascular risk and functional burden (OR: 0.85; CI: 0.75, 0.96). Reallocating 24 min of LPA to MVPA was associated with a 14% lower odds of cardiovascular risk and functional burden (OR: 0.86; CI: 0.75, 0.99). In longitudinal isotemporal models, similar beneficial associations were observed when 10-year increases in MVPA replaced time in ST or LPA. Findings suggest that maintaining an MVPA dose reflecting daily physical activity recommendations in early midlife is associated with lower odds of cardiovascular risk and functional burden later in midlife.

Weaving Healthy Families Program: Promoting Resilience While Reducing Violence and Substance Use

PURPOSE

We examine pilot results for the culturally adapted Weaving Healthy Families (WHF) program to promote resilience and wellness while preventing substance abuse and violence among Native American (NA) families.

METHODS

Results were drawn from paired sample t tests and analyses of variance (ANOVA) with a convenience sample of 24 adults and adolescents from eight NA families (pretest, posttest, and, where available, 6-month postintervention).

RESULTS

Along with substance abuse reduction and prevention, t test results indicated reductions in (a) adult depressive symptoms and improvements in adult conflict resolution and health behaviors; (b) adolescent wellness; and (c) adult and adolescent resilience, communal mastery, social support, and sugar-sweetened beverage consumption. ANOVA tests revealed reductions in adult psychological and physical violence and improvements in adult and adolescent family resilience, family environment, and emotional regulation.

CONCLUSIONS

Results reveal promising preliminary results for the WHF program to promote resilience and thriving while reducing risk for substance abuse and violence in NA families.

Predictors of change in cardiovascular disease risk and events following gastric bypass: a 7-year prospective multicenter study

BACKGROUND

Change in short-term (i.e., 10-year) and lifetime risk of cardiovascular disease (CVD) following Roux-en-Y gastric bypass (RYGB) has significant heterogeneity.

OBJECTIVE

To identify predictors of change in CVD risk and cardiovascular events following RYGB.

METHODS

Between 2006-2009, 1625 adults without a history of CVD enrolled in a prospective cohort study and underwent RYGB at 1 of 10 U.S. hospitals. Participants were followed annually for a maximum of 7 years. Associations between presurgery characteristics (anthropometric, sociodemographic, physical and mental health, alcohol/drug use, eating behaviors) and 1) pre to postsurgery change in 10 year and lifetime atherosclerotic CVD (ASCVD) risk scores, respectively, and 2) having a CVD event (nonfatal myocardial infarction, stroke, ischemic heart disease, congestive heart failure, angina, percutaneous coronary intervention, coronary artery bypass grafting, or CVD-attributed death) as repeated measures (yr 1-7) were evaluated.

SETTING

Observational cohort study at ten hospitals throughout the United States.

RESULTS

Presurgery factors independently associated with decreases in both 10-year and lifetime risk scores 1-7 years post-RYGB were higher CVD risk score, female sex, higher household income, and normal kidney function. Additionally, Black race and having diabetes were independently associated with decreases in 10-year risk, while not having diabetes and a higher (better) composite mental health score were independently related to decreases in lifetime risk. A lower (worse) presurgery composite physical health score was associated with a higher CVD event risk (RR = 1.68, per 10 points).

CONCLUSION

This study identified multiple presurgery factors that characterize patients who may have more cardiovascular benefit from RYGB, and patients who might require additional support to improve their cardiovascular health.

American Indian Alcohol Use from a Sex-Specific Wellness Approach: Exploring Its Associated Physical, Behavioral, and Mental Risk and Protective Factors

PURPOSE

The top causes of death for American Indians (AIs), including heart and liver disease, are associated with alcohol use. Using the culturally based Framework of Historical Oppression, Resilience, and Transcendence (FHORT), the purpose of this article was to examine AI alcohol use from a sex-specific wellness approach, exploring its associated physical, behavioral, and mental risk and protective factors.

METHOD

Data were drawn from a cross-sectional survey with 479 AI adults in South Dakota. We employed a series of multiple hierarchical regression analyses to assess the associations of demographic (sex, age, marital status, income, and educational attainment), physical (Body Mass Index and cardiovascular risk), behavioral (smoking and health self-efficacy) and mental (depressive symptoms) factors with alcohol use.

RESULTS

Results indicated that surveyed males tended to drink three times that of females, and depressive symptoms were associated with higher levels of alcohol use.

DISCUSSION

This study highlights the need to examine AI alcohol use with sex in mind.

Cardiovascular Health among U.S. Indigenous Peoples: A Holistic and Sex-Specific Systematic Review

PURPOSE

The purpose of this systematic review is to examine mental, sociocultural, behavioral, and physical risk and protective factors related to cardiovascular disease (CVD) and related outcomes among U.S. Indigenous peoples.

METHODS

A total of 51 articles met the inclusion criteria of research focusing factors for CVD among U.S. Indigenous peoples (Mental n= 15; Sociocultural, n =17; Behavioral/Physical, n =19).

RESULTS

This review reveals clear risks for CVD, which tended to be elevated for females. Mental health problems (depression, anxiety, PTSD/trauma, alcohol and other drug (AOD) abuse) were clearly associated with CVD, along with enculturation, social support, and the social environment-including discrimination and trauma. Poor diet and obesity, diabetes, hypertension, cholesterol were behavioral or physical factors.

DISCUSSION

Overall, identified research was limited and in beginning stages, lacking more information on etiology of the interconnections across sex and the mental, sociocultural, and behavioral determinants of CVD.

Changes in physical and mental health are associated with cardiovascular disease incidence in postmenopausal women

BACKGROUND

physical and mental health are important risk factors for cardiovascular disease (CVD) incidence and death among postmenopausal women. The objective of this study was to assess whether changes in physical and mental health were associated with CVD incidence and death.

METHODS

in the Women's Health Initiative Observational Study, 48,906 women (50-79 years) had complete data at baseline on physical and mental health (assessed with Short Form-36) and key covariates. Changes in self-reported physical and mental health were calculated between baseline and year 3. Incident CVD and death between year 3 and end of the study were verified with medical records.

RESULTS

over a median 8.2-year follow-up, 2,319 women developed CVD, and 1,571 women died, including 361 CVD deaths. Women with continued poor health and those with worsened health had significantly increased risk of CVD incidence, CVD-specific death and all-cause death relative to women with continued good health. Both major and minor declines in physical health were associated with an increased risk of these outcomes relative to women with no change in physical health. Only major declines in mental health were associated with poor prognosis.

CONCLUSIONS

changes in physical and mental health over 3 years were independently associated with subsequent CVD events.

Association between physical health and cardiovascular diseases: Effect modification by chronic conditions

Objectives:

This study assessed whether the physical component summary score of the RAND-36 health-related quality-of-life survey was associated with incidence of coronary heart disease, stroke, congestive heart failure, angina, or peripheral arterial disease, and whether baseline chronic conditions modified these associations.

Methods:

Analysis was limited to 69,155 postmenopausal women (50–79 years) in the Women’s Health Initiative Study who had complete data on the RAND-36, the outcomes, and covariates. Chronic conditions were defined as blood pressure ⩾140/90 mm or self-reported heart disease, diabetes, hypertension, arthritis, asthma, emphysema, cancer, and/or cholesterol-reducing medication use. Outcomes data were ascertained during follow-up (1993–2005) with medical records.

Results:

There were 2451 coronary heart disease, 1896 stroke, 1533 congestive heart failure, 1957 angina, and 502 peripheral arterial disease events during follow-up (median 8.2 years). Participants in the lowest physical component summary quintile, compared to the highest, had a significantly higher risk of developing coronary heart disease (hazard ratio (95% confidence interval) 2.0 (1.7, 2.3)), stroke (1.8 (1.5, 2.2)), angina (2.4(2.0, 2.9)), and peripheral arterial disease (3.0 (2.0, 4.4)), irrespective of chronic conditions. Interactions between physical component summary and existing chronic conditions were not significant for any outcome except congestive heart failure (p = 0.005); after adjustment, participants in the lowest physical component summary quintile and with any chronic condition had nearly a twofold higher risk of congestive heart failure (Yes = 4.4 (3.3, 5.8) vs No = 2.4 (1.2, 4.3)).

Conclusion:

We found a low physical component summary score was a significant risk factor for individual cardiovascular disease incidence in postmenopausal women.

Depression among migrant workers in Al-Qassim, Saudi Arabia

BACKGROUND

Mental disorders are common among migrant workers. There is no data on depression in Saudi Arabia among them; although, they are a third of the population.

OBJECTIVE

To determine the prevalence of depression and to assess its relationship with duration of stay and living condition in a sample of migrant workers.

METHODS

A cross-sectional survey of 400 migrant workers was conducted in Al-Qassim region of Saudi Arabia. Exposure and covariate factors were assessed with a standardized questionnaire, depression with the CES-D (Center for Epidemiological Studies on Depression) scale, and physical indices (e.g. weight, height, and blood pressure) with a general examination. Logistic regression was used to identify significant correlates of depression.

RESULTS

Depression prevalence was 20%; it did not vary by duration of stay or living condition but by age, stress, and self-reported health. In the multivariate model, those who reported 'moderate' or 'high' levels of stress were 1.7 (95% CI: 0.9, 3.1) and 3.9 (95% CI: 1.7, 9.1) times more likely to have depression (reference ='low' level), respectively. Similarly, those who rated their health either 'good' or 'fair to very poor' were 3.4 (95% CI: 1.9, 6.1) and 4.8 (95% CI: 2.3, 10.1) times more likely to have depression (reference ='excellent/very good'), respectively.

LIMITATIONS

The data were collected from one company and pertained to only male participants, and the study design could not establish temporal sequence between the exposure and outcome variables.

CONCLUSION

Depression is considerably high in this population; a large-scale and nationally representative survey is needed to validate the findings.

Correlation between health-related quality of life in the physical domain and heart rate variability in asymptomatic adults

Background

Reduced health-related quality of life in the physical domain (HRQOL_physical) has been reported to increase risks for cardiovascular disease (CVD); however, the mechanism underlying this phenomenon is still unclear. The autonomic nervous system (ANS) that connects the body and mind is a biologically plausible candidate to investigate this mechanism. The aim of our study is to examine whether the HRQOL_physical independently contributes to heart rate variability (HRV), which reflects ANS activity.

Methods

We recruited 329 physically and mentally healthy adults. All participants completed Beck Anxiety Inventory, Beck Depression Inventory and World Health Organization Questionnaire on Quality of Life: Short Form-Taiwanese version (WHOQOL-BREF). They were divided into groups of individuals having high or low scores of HRQOL_physical as discriminated by the quartile value of WHOQOL-BREF. We obtained the time and frequency-domain indices of HRV, namely variance (total HRV), the low-frequency power (LF; 0.05–0.15 Hz), which may reflect baroreflex function, the high-frequency power (HF; 0.15–0.40 Hz), which reflects cardiac parasympathetic activity, and the LF/HF ratio.

Results

There was an independent contribution of HRQOL_physical to explaining the variance in HRV after excluding potential confounding factors (gender, age, physical activity, alcohol use, depression and anxiety). Compared with the participants with high levels of HRQOL_physical, those with low levels of HRQOL_physical displayed significant reductions in variance and LF.

Conclusions

This study highlights the independent role of low HRQOL_physical in contributing to the reduced HRV in healthy adults and points to a potential underlying mechanism for HRQOL_physical to confer increased risks for CVD.

Global Quality of Life Among WHI Women Aged 80 Years and Older

BACKGROUND

The number of older adults living to age 80 and older is increasing rapidly, particularly among women. Correlates of quality of life (QOL) in very advanced ages are not known. We examined the association of demographic, social-psychological, lifestyle, and physical health variables with global QOL in a Women's Health Initiative (WHI) cohort of women aged 80 and older.

METHODS

26,299 WHI participants, who had completed a recent psychosocial and medical update, were included in these analyses. Global QOL was assessed by a single item, asking the women to rate their overall QOL on a scale from 0 to 10. Characteristics of the women were examined by the level of their transformed global QOL scores (≤50, 50-70, ≥70), and multiple regression was used to examine which demographic, social-psychological, lifestyle and health variables were independently associated with higher global QOL.

RESULTS

Social-psychological and current health variables were more strongly associated with global QOL than a history of selected comorbid conditions. In particular, higher self-rated health and fewer depressive symptoms were the most strongly associated with better global QOL in WHI women ≥80 years.

CONCLUSIONS

Interventions to reduce depressive symptoms and improve health may lead to better self-reported health and global QOL among older women. Physical and mental health screenings followed by evidence-based interventions are imperative in geriatric care.

Gender differences in quality of life perception and cardiovascular risk in a community sample

INTRODUCTION

Self-reported heath and quality of life is an independent predictor of overall and cardiovascular morbidity and mortality, and incident coronary heart disease. However, less is known regarding how gender differences in cardiovascular risk factors impact quality of life perception.

METHODS

Primary healthcare users (n=261, 158 women) were screened for cardiovascular risk factors and completed the Medical Outcomes Study Short Form (SF-36).

RESULTS

Women had significantly lower alcohol consumption, body mass index and exercise frequency than men, but more prevalent psychiatric history, depressive and anxiety symptoms, and negative affectivity. Prevalences of hypertension, diabetes, dyslipidemia and type D personality were similar between genders. Women reported significantly worse quality of life on most SF-36 subscales and gender differences were apparent in predictors of quality of life. Moreover, high negative affectivity was an independent predictor of worse general health for women, whereas high social inhibition and high anxiety had a comparable role for men.

CONCLUSION

Gender specifics in cardiovascular risk factors should be considered in prevention strategies. Women reported significantly worse quality of life, putting them at higher risk for cardiovascular morbidity and mortality. Therefore, gender differences in predictors of quality of life warrant further investigation.

Effects of a 12-Week Hatha Yoga Intervention on Metabolic Risk and Quality of Life in Hong Kong Chinese Adults with and without Metabolic Syndrome

Objective

To determine the efficacy of a 12-week Hatha yoga intervention to improve metabolic risk profiles and health-related quality of life (HRQoL) in Chinese adults with and without metabolic syndrome (MetS).

Methods

We conducted a controlled trial within an university-affiliated hospital. 173 Chinese men and women aged 18 or above were assigned to either the yoga intervention group (n = 87) or the control group (n = 86). Primary outcomes included 12-week change in metabolic risk factors and MetS z score. Secondary outcome was HRQoL (Medical Outcomes Short Form Survey at 12 weeks).

Results

The mean age of participants was 52.0 (SD 7.4, range 31-71) years. Analysis involving the entire study population revealed that the yoga group achieved greater decline in waist circumference (p<0.001), fasting glucose (p<0.01), triglycerides (p<0.05), and MetS z score (p<0.01). Yoga training also improved general health perceptions (p<0.01), physical component score (p<0.01), and social functioning (p<0.01) domains score of HRQoL. However, no significant differences between groups were observed in the mean change of systolic/diastolic blood pressures or high-density lipid protein cholesterol (all p>0.05). There were no significant differences in the intervention effects on waist circumference and MetS z score between the MetS subgroups (both p>0.05).

Conclusion

A 12-week Hatha yoga intervention improves metabolic risk profiles and HRQoL in Chinese adults with and without MetS.

Association between physical and mental health-related quality of life and adverse outcomes; a retrospective cohort study of 5,272 Scottish adults

Background

Health-related quality of life (HRQoL) is associated with adverse outcomes in disease-specific populations. This study examines whether it is also independent predictor of incident cancer, coronary heart disease (CHD) and mortality in the general population.

Methods

The records of adult participants in the Scottish Health Survey 2003 were linked with hospital admissions, cancer registrations and death certificates. Cox proportional hazard models were used to explore the associations between quintiles of physical and mental component summary score (PCS and MCS respectively) of the SF-12 and adverse outcomes. Higher quintiles of both PCS and MCS indicate better health status.

Results

Among the 5,272 study participants, the mean PCS score was 49 (standard deviation (SD) 10.3). Participants were followed-up for a mean of 7.6 years. On survival analysis the lowest quintile of PCS was a strong predictor of all-cause death (hazard ratio (HR) 2.81, 95% CI 1.76, 4.49), incident cancer (HR 1.63, 95% CI 1.10, 2.42), and CHD events (HR 1.99, 95% CI 1.00, 3.96), compared to the highest quintile. This association was independent of adiposity and other confounders. The mean MCS score 52 (SD 8.8). MCS quintile was not associated with incident cancer and CHD, and the association between MCS and all-cause death (HR 1.33, 95% CI 1.01, 1.75) became non-significant after adjustment for adiposity.

Conclusion

Physical HRQoL is a significant predictor of a range of adverse outcomes, even after adjustment for adiposity and other confounders. This study highlights the importance of perceived health in the general population.

The priority group index: a proposed new method incorporating high risk and population burden to identify target populations for public health interventions

CONTEXT

Selection of priority groups is important for health interventions. However, no quantitative method has been developed.

OBJECTIVES

To develop a quantitative method to support the process of selecting priority groups for public health interventions based on both high risk and population health burden.

DESIGN

Secondary data analysis of the 2010 Canadian Community Health Survey.

SETTING

Canadian population.

PARTICIPANTS

Survey respondents.

METHODS

We identified priority groups for 3 diseases: heart disease, stroke, and chronic lower respiratory diseases. Three measures--prevalence, population counts, and adjusted odds ratios (OR)--were calculated for subpopulations (sociodemographic characteristics and other risk factors). A Priority Group Index (PGI) was calculated by summing the rank scores of these 3 measures.

RESULTS

Of the 30 priority groups identified by the PGI (10 for each of the 3 disease outcomes), 7 were identified on the basis of high prevalence only, 5 based on population count only, 3 based on high OR only, and the remainder based on combinations of these. The identified priority groups were all in line with the literature as risk factors for the 3 diseases, such as elderly people for heart disease and stroke and those with low income for chronic lower respiratory diseases. The PGI was thus able to balance both high risk and population burden approaches in selecting priority groups, and thus it would address health inequities as well as disease burden in the overall population.

CONCLUSIONS

The PGI is a quantitative method to select priority groups for public health interventions; it has the potential to enhance the effective use of limited public resources.
