The Contribution of Material, Behavioral, Psychological, and Social-Relational Factors to Income-Related Disparities in Cardiovascular Risk Among Older Adults
Ontology highlight
ABSTRACT: Objective
This study explored how material, behavioral, psychological, and social-relational factors contribute to income-related disparities in cardiovascular risk among Korean adults 65 years and older. Methods
This was a secondary analysis of Korean National Health and Nutrition Examination Survey data (2013–2017), targeting 7347 older adults (≥65 years). Socioeconomic position, defined as income, was the primary indicator. The outcome was binary for predicted cardiovascular risk (<90 vs ≥90 percentile). Disparities were measured using relative index of inequality (RII). The contributions of material, behavioral, psychological, and social-relational factors were estimated by calculating percentage reduction in RII when adjusted for these factors. Results
Among men aged 65 to 74 years and women 75 years or older, the largest reductions in RII were achieved after adjusting for social-relational factors. Among men 75 years or older and women aged 65 to 74 years, adjusting for material factors resulted in the largest reductions in RII. Adjustments for behavioral factors also reduced RII for both genders aged 65 to 74 years. Conclusions
Improving the social, material, and behavioral circumstances of lower-income older adults may help address income-related disparities in cardiovascular risk in old age.

Project description:IntroductionCardiovascular disease (CVD) remains the leading cause of premature death globally and a major contributor to decreasing quality of life. In the present study, we investigated the contribution of social, behavioral, and physiological determinants of CVD and their different patterns among middle-aged and older adults.MethodsWe used harmonized data from 6 nationally representative individual-level longitudinal studies across 25 countries. We restricted the age to ≥50 years and defined cases as a self-reported history of CVD. The exposure variables were the demographic status (age and sex), socioeconomic position (education level, employment, and household income level), social connections (marital status and family size), behavioral factors (smoking, alcohol drinking, and frequency of moderate to vigorous physical activity), and physiological risk factors (obesity, presence of hypertension, and presence of diabetes). Mixed logistic regression models were fitted to investigate the associations, and dominance analysis was conducted to examine the relative contributions.ResultsIn total, 413,203 observations were included in the final analysis, with the CVD prevalence ranging from 10.4% in Mexico to 28.8% in the United States. Physiological risk factors were the main driver of CVD prevalence with the highest dominance proportion, which was higher in developing countries (China, 57.5%; Mexico, 72.8%) than in developed regions (United States, England, 10 European countries, and South Korea). Socioeconomic position and behavioral factors also highly contributed but were less significant in developing countries than in developed regions. The relative contribution of socioeconomic position ranged from 9.4% in Mexico to 23.4% in the United States, and that of behavioral factors ranged from 5.7% in Mexico to 26.1% in England.ConclusionThe present study demonstrated the different patterns of determinant contributions to CVD prevalence across developing and developed countries. With the challenges produced by different risk factors, the implementation of tailored prevention and control strategies will likely narrow disparities in the CVD prevalence by promoting health management and enhancing the capacity of health systems across different countries.

Project description:Background and objectivesSocioeconomic disparities in cardiovascular health among adults have been documented, but disparities during adolescence are less understood. In this study, we examined secular trends in cardiovascular risk factors and disparities among US adolescents.MethodsWe analyzed NHANES data from 1999 to 2014, including 11 557 (4854 fasting) participants aged 12 to 19 years. To examine trends in cardiovascular risk factors, adolescents were stratified into 3 groups on the basis of family poverty-income ratio: low income (poverty-income ratio, <1.3), middle income (≥1.3 and <3.5), and high income (≥3.5).ResultsFrom 1999 to 2014, the prevalence of obesity increased (16.3%-20.9%, P = .001) but only among low- and middle-income adolescents, with significant disparities in prevalence by income (21.6% vs 14.6% among low- versus high-income adolescents, respectively, in 2011-2014). In addition, there were significant and persistent disparities in the prevalence of smoking (20.7% vs 7.3% among low- versus high-income adolescents, respectively, in 2011-2014), low-quality diet (68.9% vs 55.4%), and physical inactivity (25.6% vs 17.0%). No significant disparities were observed in the prevalence of prediabetes and diabetes, hypertension, or hypercholesterolemia, although the prevalence of prediabetes and diabetes nearly doubled (11.9%-23.1%, P < .001) among all adolescents from 1999 to 2014. Overall, the prevalence of adolescents with 2 or more risk factors declined, but this decline was only significant for high-income adolescents (44.1%-29.1%, P = .02).ConclusionsRecent improvements in cardiovascular health have not been equally shared by US adolescents of varying socioeconomic status.

Project description:Repeated exposure to social stress can precipitate the development of psychosocial disorders including depression and comorbid cardiovascular disease. While a major component of social stress often encompasses physical interactions, purely psychological stressors (i.e. witnessing a traumatic event) also fall under the scope of social stress. The current study determined whether the acute stress response and susceptibility to stress-related consequences differed based on whether the stressor consisted of physical versus purely psychological social stress. Using a modified resident-intruder paradigm, male rats were either directly exposed to repeated social defeat stress (intruder) or witnessed a male rat being defeated. Cardiovascular parameters, behavioral anhedonia, and inflammatory cytokines in plasma and the stress-sensitive locus coeruleus were compared between intruder, witness, and control rats. Surprisingly intruders and witnesses exhibited nearly identical increases in mean arterial pressure and heart rate during acute and repeated stress exposures, yet only intruders exhibited stress-induced arrhythmias. Furthermore, re-exposure to the stress environment in the absence of the resident produced robust pressor and tachycardic responses in both stress conditions indicating the robust and enduring nature of social stress. In contrast, the long-term consequences of these stressors were distinct. Intruders were characterized by enhanced inflammatory sensitivity in plasma, while witnesses were characterized by the emergence of depressive-like anhedonia, transient increases in systolic blood pressure and plasma levels of tissue inhibitor of metalloproteinase. The current study highlights that while the acute cardiovascular responses to stress were identical between intruders and witnesses, these stressors produced distinct differences in the enduring consequences to stress, suggesting that witness stress may be more likely to produce long-term cardiovascular dysfunction and comorbid behavioral anhedonia while exposure to physical stressors may bias the system towards sensitivity to inflammatory disorders.

Project description:Background and objectivesSuccessful aging has been described as a multifactorial and dynamic process. The aims of the study were to detect aging trajectories of physical function and behavioral, psychological, and social well-being; and to explore the correlations between functional versus well-being trajectories by age group.Research design and methodsData were gathered from the Swedish National Study on Aging and Care in Kungsholmen (N = 1,375). Subjects' physical function was assessed through walking speed and chair-stand tests, behavioral well-being through participation in mental and physical activities, psychological well-being through life satisfaction and positive affect, and social well-being through social connections and support. All exposures were standardized (z-scores). Linear mixed models were used to estimate trajectories of physical function and well-being over a 12-year follow-up.ResultsThe steepest declines were seen for physical function (relative change [RC] in z-scores across ages; RC = 3.01), followed by behavioral well-being (RC = 2.15), psychological well-being (RC = 2.01), and social well-being (RC = 0.76). Correlations between physical function and the different well-being domains were weak, especially for slopes. Stronger intercept correlations were observed among the oldest-compared to the youngest-old, especially with behavioral (r = 0.39 vs r = 0.24) and psychological (r = 0.33 vs r = 0.22) well-being.Discussion and implicationsPhysical function declines the fastest throughout aging. The different well-being domains decline at a slower rate, which may be a possible sign of compensation against age-related functional decline, especially among the youngest-old, for whom discordances between physical function and the different well-being domains were more common.

Project description:ImportanceLarge improvements in the control of risk factors for cardiovascular disease have been achieved in the United States, but it remains unclear whether adults in all socioeconomic strata have benefited equally.ObjectiveTo assess temporal trends in 10-year predicted absolute cardiovascular risk and cardiovascular risk factors among US adults in different socioeconomic strata.Design, setting, and participantsA cross-sectional analysis was conducted using data on adults 40 to 79 years of age without established cardiovascular disease from the 1999 to 2014 National Health and Nutrition Examination Survey.ExposuresSocioeconomic status was based on the family income to poverty ratio and participants were divided into the following 3 groups: high income (family income to poverty ratio, ?4), middle income (>1 and <4), or at or below the federal poverty level (?1).Main outcomes and measuresWe assessed predicted absolute cardiovascular risk using the pooled cohort equation. We assessed the following 4 risk factors: systolic blood pressure, smoking status, diabetes, and total cholesterol.ResultsOf the 17?199 adults whose data were included in the study (8828 women and 8371 men; mean age, 54.4 years), from 1999-2014, trends in the percentage of adults with predicted absolute cardiovascular risk of 20% or more, mean systolic blood pressure, and the percentage of current smokers varied by income strata (P???.02 for interaction). For adults with incomes at or below the federal poverty level, there was little evidence of a change in any of these outcomes across survey years (cardiovascular risk ?20%, 14.9% [95% CI, 12.9%-16.8%] in 1999-2004; 16.5% [95% CI, 13.7%-19.2%] in 2011-2014; P?=?.41; mean systolic blood pressure, 127.6 [95% CI, 126.1-129.0] mm Hg in 1999-2004; 126.8 [95% CI, 125.2-128.5] mm Hg in 2011-2014; P?=?.44; and smoking, 36.5% [95% CI, 32.1%-41.0%] in 1999-2004; 36.0% [95% CI, 31.1%-40.8%] in 2011-2014; P?=?.87). For adults in the high-income stratum, these variables decreased across survey years (cardiovascular risk ?20%, 12.0% [95% CI, 10.7%-13.3%] in 1999-2004; 9.5% [95% CI, 8.2%-10.7%] in 2011-2014; P?=?.003; systolic blood pressure, 126.0 [95% CI, 125.0-126.9] mm Hg in 1999-2004; 122.3 [95% CI, 121.3-123.3] mm Hg in 2011-2014; P?<?.001; and smoking, 14.1% [95% CI, 12.0%-16.2%] in 1999-2004; 8.8% [95% CI, 6.6%-11.0%] in 2011-2014; P?=?.001). Trends in the percentage of adults with diabetes and the mean total cholesterol level did not vary by income.Conclusions and relevanceAdults in each socioeconomic stratum have not benefited equally from efforts to control cardiovascular risk factors.

Project description:Starkly unequal built and social environments among urban neighborhoods are part of the explanation for health disparities in the United States. This study is a qualitative investigation of the ways that residents of a low-income neighborhood in Madison, WI, use and interpret nearby neighborhood places. Specifically, I ask how and why certain places may facilitate beneficial behavioral and social mechanisms that impact health. I develop the organizing concept of "vital places": nearby destinations that are important to and frequently-used by neighborhood residents, and that have theoretical relevance to health. I argue that conceiving of certain places as vital integrates our understanding of the essential components of places that are beneficial to health, while also allowing policy-makers to be creative about the ways they intervene to improve the life chances of residents in disadvantaged neighborhoods. I synthesize the findings into the characteristics of three types of vital places. First, I find that a convenient, comprehensive, and affordable food source can facilitate a healthy diet. An attractive, accessible, and safe recreational facility can support greater physical and social activity. Finally, shared, casual, focused social spaces provide opportunities to create and sustain supportive social ties. This study adds depth and complexity to the ways we conceptualize health-relevant community assets and provides insight into revitalization strategies for distressed low-income housing.

Project description:Favorable cardiovascular health (FCH) is associated with healthy longevity and reduced cardiovascular mortality risk. However, limited work has investigated the distribution of FCH in older age or considered the antecedents of FCH. Based on prior work linking psychological well-being with cardiovascular endpoints, higher psychological well-being was hypothesized to be associated with increased likelihood of maintaining FCH over time.Data were from the English Longitudinal Study of Ageing. The first study wave (2002-2003) included men and women aged ?50 years. The analytic sample (N=4,925) was restricted to individuals without baseline cardiovascular disease and with clinical data from three follow-ups through 2013. Psychological well-being was assessed with 17 items from the Control, Autonomy, Satisfaction, and Pleasure scale. FCH was defined as being a non-smoker, diabetes-free, and having healthy levels of blood pressure, cholesterol, and BMI (FCH scores ranged from 0-5). Statistical analyses conducted in 2016-2017 used linear mixed models to examine associations between psychological well-being and FCH scores over time. Secondary analyses examined cardiovascular-related mortality.Only 1% of participants had achieved complete FCH at study baseline. Adjusting for sociodemographic factors and depression, greater psychological well-being was associated with higher FCH scores across time (?=0.05, 95% CI=0.02, 0.08), but not rate of change in FCH. Psychological well-being was also associated with a 29% reduced risk of cardiovascular-related mortality in multivariable-adjusted models.Findings suggest that psychological well-being is associated with having FCH at older ages, and add to knowledge of assets that may increase likelihood of healthy aging.

Project description:High blood pressure causes over 10 million preventable deaths annually globally. Populations in low- and middle-income countries suffer the most, experiencing increased uncontrolled blood pressure and cardiovascular disease (CVD) deaths. Despite improvements in high-income countries, disparities persist, notably in the United States, where Black individuals face up to 4× higher CVD mortality than White individuals. Social determinants of health encompass complex, multidimensional factors linked to an individual's birthplace, upbringing, activities, residence, workplaces, socioeconomic and environmental structures, and significantly affect health outcomes, including hypertension and CVD. This review explored how social determinants of health drive disparities in hypertension and related CVD morbidity from a socioecological and life course perspective. We present evidence-based strategies, emphasizing interventions tailored to specific community needs and cross-sector collaboration to address health inequalities rooted in social factors, which are key elements toward achieving the United Nations' Sustainable Development Goal 3.4 for reducing premature CVD mortality by 30% by 2030.

Project description:IntroductionEarly childhood caries (ECC) is a complex, multifactorial oral disease that is a major public health concern because it is prevalent, profoundly alters a child's quality of life, is difficult to treat effectively, and has a distressing tendency to recur following treatment.ObjectivesThe purpose of the study was to examine social, psychological, and behavioral predictors of salivary bacteria and yeast in young children at risk for ECC.MethodsA sample of 189 initially caries-free preschool children was assessed for child stress physiology from salivary cortisol, child and family stress exposure, diet, oral health behaviors, and sociodemographic risks. Multiple logistic regression analysis was implemented to examine the associations between these risk factors and cariogenic microorganisms: mutans streptococci (MS), lactobacilli (LB), and Candida species.ResultsHigher baseline salivary cortisol (odds ratio [OR] = 6.26; 95% confidence level [CL], 1.69-23.16) and a blunted response to an acute laboratory stressor (OR = .56; 95% CL, .37-.83) were associated with an increased likelihood of elevated salivary MS (≥105 colony-forming units/mL) in caries-free children. Sociodemographic risk for cariogenic microorganisms was also found. Specifically, lower education attainment of the parent/primary caregiver was associated with children being more likely to carry salivary Candida species and elevated salivary MS; in addition, children from households with an unemployed parent/primary caregiver were more likely (OR = 3.13; 95% CL, 1.2-8.05) to carry salivary Candida species and more likely (OR = 3.03; 95% CL, 1.25-7.33) to carry elevated levels of MS and/or salivary Candida and/or LB.ConclusionsThe impact of sociodemographic risk and stress physiology on cariogenic disease processes are evident prior to ECC onset. The findings provide novel data on the early onset of cariogenic processes in children and the importance of considering sociodemographic, psychosocial, and behavioral factors when judging ECC risk.Knowledge transfer statementThe findings provide valuable and novel findings that, pre-ECC onset, the caries disease process is explicable from a detailed assessment of behavioral, sociodemographic, and psychosocial stress variables.

Project description:BackgroundMedical financial burden includes material, behavioral, and psychological hardship and has been underinvestigated among adult survivors of childhood cancer.MethodsA survey from 698 survivors and 210 siblings from the Childhood Cancer Survivor Study was analyzed. The intensity of financial hardship was estimated across 3 domains: 1) material, including conditions that arise from medical expenses; 2) behavioral, including coping behaviors to manage medical expenses; and 3) psychological hardship resulting from worries about medical expenses and insurance, as measured by the number of instances of each type of financial hardship (0, 1-2, and ≥3 instances). Multivariable logistic regressions were conducted to examine the clinical and sociodemographic predictors of experiencing financial hardship (0-2 vs ≥3 instances).ResultsThe intensity of financial hardship did not significantly differ between survivors and siblings. Survivors reported more instances of material hardship than siblings (1-2 instances: 27.2% of survivors vs 22.6% of siblings; ≥3 instances: 15.9% of survivors vs 11.4% siblings; overall P = .03). In multivariable regressions, insurance was protective against all domains of financial hardship (behavioral odds ratio [OR], 0.12; 95% confidence interval [CI], 0.06-0.22; material OR, 0.37; 95% CI, 0.19-0.71; psychological OR, 0.10; 95% CI, 0.05-0.21). Survivors who were older at diagnosis, female, and with chronic health conditions generally had higher levels of hardship. Brain radiation and alkylating agents were associated with higher levels of hardship.ConclusionsMaterial, behavioral, and psychological financial burden among survivors of childhood cancer is common.
