Subjective and objective evaluations of health among middle-aged and older veterans with hypertension

Why is there a gap in self-rated health among people with hypertension in Zambia? A decomposition of determinants and rural‒urban differences

BACKGROUND

Hypertension affects over one billion people globally and is one of the leading causes of premature death. Low- and middle-income countries, especially the sub-Saharan Africa region, bear a disproportionately higher share of hypertension globally. Recent evidence shows a steady shift in the burden of hypertension from more affluent and urban populations towards poorer and rural communities. Our study examined inequalities in self-rated health (SRH) among people with hypertension and whether there is a rural‒urban gap in the health of these patients. We then quantified factors driving the health gap. We also examined how much HIV accounts for differences in self-rated health among hypertension patients due to the relationship between HIV, hypertension and health in sub-Saharan Africa.

METHODS

We utilized the Zambia Household Health Expenditure and Utilization Survey for data on SRH and other demographic and socioeconomic controls. District HIV prevalence information was from the Zambia Population-Based HIV Impact Assessment (ZAMPHIA) survey. We applied the Linear Probability Model to assess the association between self-rated health and independent variables as a preliminary step. We then used the Blinder-Oaxaca decomposition to identify self-rated health inequality between urban and rural patients and determine determinants of the health gap between the two groups.

RESULTS

Advanced age, lower education and low district HIV prevalence were significantly associated with poor health rating among hypertension patients. The decomposition analysis indicated that 45.5% of urban patients and 36.9% of rural patients reported good self-rated health, representing a statistically significant health gap of 8.6%. Most of the identified health gap can be attributed to endowment effects, with education (73.6%), district HIV prevalence (30.8%) and household expenditure (4.8%) being the most important determinants that explain the health gap.

CONCLUSIONS

Urban hypertension patients have better SRH than rural patients in Zambia. Education, district HIV prevalence and household expenditure were the most important determinants of the health gap between rural and urban hypertension patients. Policies aimed at promoting educational interventions, improving access to financial resources and strengthening hypertension health services, especially in rural areas, can significantly improve the health of rural patients, and potentially reduce health inequalities between the two regions.

Psychological factors and self-rated health: An observative study on cardiological patients

This study investigated the association of illness representations, awareness of bodily states and health complaints to self-rated health in N = 150 consecutive patients with heart disease (ischaemic disease, heart failure and heart valve disease) and explored differences between ‘health optimist’ and ‘health pessimist’ patients. After controlling for medical variables, health complaints accounted for 14.2 per cent of patients’ self-rated health, and illness representations contributed for another 16.2 per cent; body awareness was not associated with self-rated health. Also, ‘optimists’ tended to see less negative consequences from their illness and perceived greater control over illness treatment compared to ‘pessimists’. Targeting symptoms and illness representations may optimize rehabilitation outcomes.

Identifying modifiable factors associated with health optimism in older adults

OBJECTIVE

Despite the documented importance of health optimism for enhancing health outcomes, very little work has been done to examine who experiences health optimism and under what conditions. The present study sought to identify modifiable factors associated with health optimism that could constitute the focus of future intervention efforts designed to promote health optimism among older people.

DESIGN

Participants were 453 (44% males) community-based Western Australians aged 60+ years (M = 70.39 years, SD = 6.06). Participants completed questionnaires to assess sociodemographic characteristics and provided information relating to physical and psychological health status.

RESULTS

Almost a quarter of participants (24%; n = 108) were classified as health optimists. Results from a multivariate regression analysis found quality of life, psychological well-being, and age to be directly and positively associated with health optimism. A subsequent path analytic model found depression (negatively) and self-efficacy (positively) to be indirectly associated with health optimism via both psychological well-being and quality of life.

CONCLUSION

These findings extend the limited evidence on health optimism in older adults by identifying various modifiable factors that may constitute potential areas of focus for future interventions designed to enhance health outcomes via the fostering of health optimism.

Hypertension Status and Associations with Self-Rated Health and General Practitioner Health Seeking in a Rural Australian Cohort

Hypertension is the most frequently managed condition by Australian general practitioners (GP). Knowledge of hypertension and blood pressure (BP) values may motivate individuals to seek GP management. Our study aims to determine the associations of knowledge of BP values, BP perception, GP health seeking, and self-rated health (SRH) in a rural population. Two-hundred and seventy-eight (278) residents responded to the health survey on socio-demographic profile, medical history, BP knowledge and perception, SRH, and GP visit frequency. Associations were evaluated using Chi-squared test and multivariate logistic regression. Cohort mean age was 63.6 (12.4) years with 63.3% females. Hypertension (37.8%) was the most common condition. GP visits were made at least once every month (19.1%), every 2–6 months (35.6%), >6 months (11.5%), or only when needed (29.5%). Univariate analyses showed age, education, alcohol consumption, comorbidities, hypertension status, and SRH were significantly associated with visit frequency. After adjustments, hypertension status (OR = 3.6, 95% CI [1.7, 7.9]) and poor SRH (OR = 3.1, 95% CI [1.4, 7.0]) were significantly associated with frequent monthly visits. Our cohort demonstrated that having hypertension and poor self-rated health were associated with frequent monthly GP visits. The perception of high blood pressure does not drive seeking additional GP input.

Self-rated health as a predictor of outcomes of type 2 diabetes patient education programmes in Denmark

OBJECTIVE

To explore if self-rated health (SRH) can predict differences in outcomes of patient education programmes among patients with type 2 diabetes over time.

STUDY DESIGN

This is an observational cohort study conducted among 83 patients with type 2 diabetes participating in patient education programmes in the Capital Region of Denmark.

METHODS

Questionnaire data were collected by telephone interview at baseline and 2 weeks (77 participants, 93%) and 12 months (66, 80%) after the patient education ended. The seven-scale Health Education Impact Questionnaire (HeiQ) was the primary outcome. The independent variable was SRH, which was dichotomized into optimal or poor SRH. Changes over time were assessed using mean values and standard deviation (SD) at each time point and Cohen effect sizes. Odds ratios and 95% confidence intervals were calculated for the likelihood of having poor SRH for each baseline sociodemographic and health-related variable.

RESULTS

Twelve months after patient education programmes, 60 (72%) patients with optimal SRH at baseline demonstrated increased self-management skills, overall acceptance of chronic illness, positive social interaction with others, and improved emotional well-being. Participants with poor SRH (23, 28%) reported no improvements over time. Not being married (odds ratio [OR] 7.79, P < 0.001), living alone (OR 4.93, P = 0.003), having hypertension (OR 8.00, P = 0.031), and being severely obese (OR 4.07, P = 0.009) were significantly associated with having poor SRH. After adjusting for sex, age and vocational training, marital status (OR 9.35, P < 0.001), cohabitation status (OR = 4.96, P = 0.005) and hypertension (OR 10.9, P = 0.03) remained associated with poor SRH.

CONCLUSIONS

We found a strong association between SRH and outcomes of patient education, as measured by the HeiQ, at 12 months. Only participants with optimal SRH appeared to benefit from patient education. Other patient characteristics may be responsible to explain the observed difference between patients with optimal and poor SRH.

Concordance between Self-Reported and Physician-Reported Chronic Co-morbidity among Disabled Older Adults

La discordance entre les auto-rapports et les dossiers médicaux reflètent des éléments concernant les patients et les prestataires qui ont des implications pour la recherche et la gestion. Cette étude a examiné la discordance et les facteurs socio-démographiques qui expliquent la concordance. Un échantillon téléologique de 402 personnes âgées handicapées a été interrogés à l’aide d’un questionnaire structuré. On a trouvé les concordances les plus hauts pour le diabète, l’accident cardiovasculaire (CVA), et le cancer, et les plus bas pour l’arthrite, et les conditions rénales et digestives. Les facteurs explicatifs importants inclurent: (a) l’âge dans l’explication de la concordance dans l’hypertension; (b) l’ethnicité en expliquant la concordance dans l’arthrite et le cancer; (c) la situation de famille en expliquant la concordance dans les maladies de la thyroïde; (d) l’éducation pour expliquer la concordance dans les conditions gastro-intestinales, et (e) l’état fonctionnel en expliquant la concordance dans maladies respiratoires, gastro-intestinales et thyroïdiennes. La comorbidité a accrue la concordance dans toutes les conditions de santé, et a diminué la concordance pour l’hypertension. Une enquête plus poussée est nécessaire pour examiner la cause des disparités entre les deux sources d’information.

Later life health optimism, pessimism and realism: psychosocial contributors and health correlates

Prior research has established positive outcomes of health optimism (appraising one's health as good despite poor objective health (OH)) and negative outcomes of health pessimism (appraising health as poor despite good OH), yet little is known about their contributors. We examined the role of psychosocial factors (life event stress, depression, dispositional optimism, perceived social support) in health realism (appraising health in accordance with OH), optimism and pessimism among 489 older men and women. We then accounted for the psychosocial factors when examining multiple health correlates of health realism, optimism and pessimism. Controlling for age, gender and income, regression results indicate that depression and social support were associated with less health optimism, while dispositional optimism was associated with greater health optimism among those in poor OH. Dispositional optimism was associated with less health pessimism and life event stress was associated with greater pessimism among those in good OH. Beyond the effects of the psychosocial factors, structural equation model results indicate that health optimism was positively associated with healthy behaviours and perceived control over one's health; health pessimism was associated with poorer perceived health care management. Health optimism and pessimism have different psychosocial contributors and health correlates, validating the health congruence approach to later life well-being, health and survival.

Predicting survival and morbidity-free survival to very old age

As life expectancy continually increases, it is imperative to identify determinants of survival to the extreme end of the lifespan and more importantly to identify factors that increase the chance of survival free of major morbidities. As such, the current study assessed 45 common disease factors as predictors of survival and morbidity-free survival to age 85 years. Within the Rotterdam Study, a population-based cohort, we evaluated morbidity-free participants who were able to attain age 85 within the study duration (n = 2,008). Risk factors were assessed at baseline (1990-1993), and mortality and morbidities were then collected continuously until mortality or the occurrence of their 85th birthday (average time of 7.9 years). Risk factors included demographic and lifestyle variables, health and morbidity indicators and physiological makers. Major morbidities examined included dementia, cancer, cerebrovascular accident, heart failure and myocardial infarction. Logistic regression analyses demonstrated that many of the variables were independently predictive for survival and for morbidity-free ageing to 85 years. These included being female, absence of left ventricular abnormalities, stable body weight, unimpaired instrumental activities of daily living, lower C-RP levels and higher levels of femoral neck bone mineral density and albumin. Relative to non-survival, predictors were stronger for morbidity-free survival than for total survival or survival with morbidity. This suggests that lifespan and healthy survival to older age can be relatively well predicted. Understanding predictors of a long and healthy lifespan is vital for developing primary and secondary preventions to help improve the quality of life of older adults and for reducing the financial burden of the rapidly escalating ageing population.

Diabetes-related support, regimen adherence, and health decline among older adults

OBJECTIVES. Social support is generally conceptualized as health promoting; however, there is little consensus regarding the mechanisms through which support is protective. Illness support has been proposed to promote regimen adherence and subsequent prevention of health decline. We hypothesize that (a) support for regimen adherence is negatively associated with self-reported health decline among older diabetic adults and that (b) regimen adherence is negatively associated with health decline among older diabetic adults.

METHODS

We used the Health and Retirement Study data on individuals over the age of 60 years with type 2 diabetes mellitus (n = 1,788), examining change in self-reported health status over a 2-year period using binomial and cumulative ordinal logistic regression models.

RESULTS

Diabetic support is not significantly associated with health decline, but it is strongly associated with adherence to health-promoting activities consisting of a diabetic regimen. Therefore, the extent to which one receives illness support for a given regimen component is highly positively associated with adhering to that component, although this adherence does not necessarily translate into protection against perceived decline in health.

CONCLUSIONS

Illness-related support appears to be a mechanism through which social support matters in the diabetic population. Although this relationship did not extend to prevention of health status decline among diabetics, the relationship between support and illness management is promising.

Racial differences in self-rated health at similar levels of physical functioning: an examination of health pessimism in the health, aging, and body composition study

BACKGROUND

The health pessimism hypothesis suggests that Black elders are more pessimistic about health than Whites and therefore tend to report lower self-rated health (SRH) at comparable health status. The current analysis examined the factors associated with SRH and tested the health pessimism hypothesis among older adults at similar levels of physical functioning.

METHODS

The study example included 2,729 Health, Aging, and Body Composition study participants aged 70-79 years. We used hierarchical logistic regression to examine the association between race and SRH while adjusting for demographic, physical health, and psychosocial factors. The analyses were repeated for participants at similar levels of objective functioning to test the health pessimism hypothesis.

RESULTS

The association between race and SRH remained independent of physical and psychosocial health variables, with Whites being 3.7 times more likely than Black elders to report favorable SRH. This association was significant at each level of physical functioning and greater at the higher (odds ratio [OR] = 5.5) versus lower (OR = 2.2) levels of functioning.

CONCLUSIONS

The results suggest greater health pessimism among Black elders and expand previous work by including objective functioning in multidimensional models to deconstruct race variations in the SRH of older adults.

Native American Elders' Health Congruence

Addressing the need to explore how Native American (NA) elders' subjective health (SH) compares to their objective health (OH; chronic disease conditions), we examined whether: congruence between 8191 NA elders' SH and OH parallels that of non-NA elders; health optimism (SH > OH) is protective and health pessimism (SH < OH), is detrimental; and whether gender moderates links between health congruence and health-related outcomes. Results comparing health optimists and pessimists to realists in functioning, hospitalizations, and social engagement showed optimists experienced better outcomes; pessimists had poorer outcomes; the role of health congruence differed by gender. Findings suggest implications for improving health-related outcomes among NA elders.

Among older adults, the responsiveness of self-rated health to changes in Charlson comorbidity was moderated by age and baseline comorbidity

OBJECTIVE

To examine the impact of changes in comorbidity--as measured by the Charlson comorbidity index--on self-rated health in a large sample of community-dwelling elderly over a 1-year period, and to examine the differential effects of changes in specific Charlson diagnostic categories.

STUDY DESIGN AND SETTING

Longitudinal survey data on self-rated health were linked with Medicare inpatient, outpatient, and physician visit data for 30,535 U.S. elderly residing in Pennsylvania. Multivariate logistic regression with fractional polynomials was used to model relationships involving baseline and changing Charlson comorbidity with self-rated health decline, and to evaluate covariate interactions.

RESULTS

Comorbidity change was associated with greater likelihood of worsened self-rated health, but the relationship was nonlinear and was moderated by age and baseline comorbidity. The impact of comorbidity change appeared to be less among older individuals and those with higher baseline comorbidity. Declines in self-rated health were most likely following new diagnoses for metastatic tumors, paralysis, and dementia.

CONCLUSION

Self-rated health is responsive to changes in Charlson comorbidity, but nonlinearity and interactions suggest complexity in how elderly respond to comorbidity change. Younger individuals and those with initially low comorbidity are more likely to reduce self-ratings of health following new diagnoses for chronic conditions.

Racial differences in blood pressure control: potential explanatory factors

OBJECTIVE

The objective of the study was to identify potential explanatory factors for racial differences in blood pressure (BP) control.

DESIGN

The design of the study was a cross-sectional study

PATIENTS/PARTICIPANTS

The study included 608 patients with hypertension who were either African American (50%) or white (50%) and who received primary care in Durham, NC.

MEASUREMENTS AND MAIN RESULTS

Baseline data were obtained from the Take Control of Your Blood pressure study and included clinical, demographic, and psychosocial variables potentially related to clinic BP measures. African Americans were more likely than whites to have inadequate baseline clinic BP control as defined as greater than or equal to 140/90 mmHg (49% versus 34%; unadjusted odds ratio [OR] 1.8; 95% confidence interval [CI] 1.3-2.5). Among factors that may explain this disparity, being older, reporting hypertension medication nonadherence, reporting a hypertension diagnosis for more than 5 years, reporting high levels of stress, being worried about hypertension, and reporting an increased number of medication side effects were related to inadequate BP control. In adjusted analyses, African Americans continue to have poor BP control relative to whites; the magnitude of the association was reduced (OR = 1.5; 95% CI 1.0-2.1). Medication nonadherence, worries about hypertension, and older age (>70) continued to be related to poor BP control.

CONCLUSIONS

In this sample of hypertensive patients, there were a number of factors associated with poor BP control that partially explained the observed racial disparity in hypertension control including age, medication nonadherence, and worry about BP. Medication nonadherence is of particular interest because it is a potentially modifiable factor that might be used to reduce the racial disparity in BP control.
