Little is known about the health impact of helping behaviors among individuals with high-risk chronic diseases such as cardiovascular disease (CVD). Using a nationally representative, longitudinal survey, we examined the subsequent health of adults with CVD (n~=~4,491) who spent time providing non-paid assistance to family and friends outside of their households compared with those who had provided no assistance. After both adjusting for baseline characteristics and using propensity score matching methods, spending up to 200~h over the prior 12~months helping others was associated with lower odds of experiencing a new CVD event or dying in the subsequent 2~years. Providing up to 100~h of assistance was associated with reporting fewer depressive symptoms. This threshold effect raises the question of whether assistance beyond a certain number of hours may impose a burden that mitigates health benefits from helping others. Health care providers could play an important role exploring ways that patients with CVD can provide beneficial levels of assistance to others in their own social networks or communities, thereby possibly also improving their own health.

UNLABELLED: Prevalence of cirrhosis among older adults is expected to increase; therefore, we studied the health status, functional disability, and need for supportive care in a large national sample of individuals with cirrhosis. A prospective cohort of individuals with cirrhosis was identified within the longitudinal, nationally representative Health and Retirement Study. Cirrhosis cases were identified in linked Medicare data via ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) codes and compared to an age-matched cohort without cirrhosis. Two primary outcome domains were assessed: (1) patients{\textquoteright} health status (perceived health status, comorbidities, health care utilization, and functional disability as determined by activities of daily living and instrumental activities of daily living), and (2) informal caregiving (hours of caregiving provided by a primary informal caregiver and associated cost). Adjusted negative binomial regression was used to assess the association between cirrhosis and functional disability. A total of 317 individuals with cirrhosis and 951 age-matched comparators were identified. Relative to the comparison group, individuals with cirrhosis had worse self-reported health status, more comorbidities, and used significantly more health care services (hospitalizations, nursing home stays, physician visits; P < 0.001 for all bivariable comparisons). They also had greater functional disability (P < 0.001 for activities of daily living and instrumental activities of daily living), despite adjustment for covariates such as comorbidities and health care utilization. Individuals with cirrhosis received more than twice the number of informal caregiving hours per week (P < 0.001), at an annual cost of US $4700 per person.

CONCLUSION: Older Americans with cirrhosis have high rates of disability, health care utilization, and need for informal caregiving. Improved care coordination and caregiver support is necessary to optimize management of this frail population.

OBJECTIVES: This study sought to (1) identify barriers to spousal support for chronic illness self-care among community-dwelling older adults; and (2) describe the potential availability of self-care support from adult children living outside of the household.

METHODS: Nationally representative US sample of chronically ill adults aged 51+ were interviewed as part of the Health and Retirement Study (N = 14,862). Both participants and their spouses (when available) reported information about their health and functioning. Participants also reported information about their contact with adult children and the quality of those relationships.

RESULTS: More than one-third (38\%) of chronically ill older adults in the US are unmarried; and when spouses are available, the majority of them have multiple chronic diseases and functional limitations. However, the vast majority of chronically ill older adults (93\%, representing roughly 60 million Americans) have adult children, with half having children living over 10 miles away. Most respondents with children (78\%) reported at least weekly telephone contact and that these relationships were positive. Roughly 19 million older chronically ill Americans have adult children living at a distance but none nearby; these children are in frequent telephone contact and respondents (including those with multiple chronic diseases) report that the relationships are positive.

DISCUSSION: As the gap between available health services for disease management and the need among community-dwelling patients continues to grow, adult children-including those living at a distance-represent an important resource for improving self-care support for people with chronic diseases.

OBJECTIVE: Although multiple noncost factors likely influence a patient{\textquoteright}s propensity to forego treatment in the face of cost pressures, little is known about how patients{\textquoteright} sociodemographic characteristics, physical and behavioral health comorbidities, and prescription regimens influence cost-related nonadherence (CRN) to medications. We sought to determine both financial and nonfinancial factors associated with CRN in a nationally representative sample of older adults.

METHODS: We used a conceptual model developed by Piette and colleagues that describes financial and nonfinancial factors that could increase someone{\textquoteright}s risk of CRN, including income, comorbidities, and medication regimen complexity. We used data from the 2004 wave of the Health and Retirement Study and the 2005 HRS Prescription Drug Study to examine the influence of factors within each of these domains on measures of CRN (including not filling, stopping, or skipping doses) in a nationally representative sample of Americans age 65+ in 2005.

RESULTS: Of the 3071 respondents who met study criteria, 20\% reported some form of CRN in 2005. As in prior studies, indicators of financial stress such as higher out-of-pocket payments for medications and lower net worth were significantly associated with CRN in multivariable analyses. Controlling for these economic pressures, relatively younger respondents (ages 65-74) and depressive symptoms were consistent independent risk factors for CRN.

CONCLUSIONS: Noncost factors influenced patients{\textquoteright} propensity to forego treatment even in the context of cost concerns. Future research encompassing clinician and health system factors should identify additional determinants of CRN beyond patients{\textquoteright} cost pressures.

CONTEXT: It is well-documented that the financial burden of out-of-pocket expenditures for prescription drugs often leads people with medication-sensitive chronic illnesses to restrict their use of these medications. Less is known about the extent to which such cost-related medication underuse is associated with increases in subsequent hospitalizations and deaths.

OBJECTIVE: We compared the risk of hospitalizations among 5401 and of death among 6135 middle-aged and elderly adults with one or more cardiovascular diseases (diabetes, coronary artery disease, heart failure, and history of stroke) according to whether participants did or did not report restricting prescription medications because of cost.

DESIGN AND SETTING: A retrospective biannual cohort study across 4 cross-sectional waves of the Health and Retirement Study, a nationally representative survey of adults older than age 50. Using multivariate logistic regression to adjust for baseline differences in sociodemographic and health characteristics, we assessed subsequent hospitalizations and deaths between 1998 and 2006 for respondents who reported that they had or had not taken less medicine than prescribed because of cost.

RESULTS: Respondents with cardiovascular disease who reported underusing medications due to cost were significantly more likely to be hospitalized in the next 2 years, even after adjusting for other patient characteristics (adjusted predicted probability of 47\% compared with 38\%, P < 0.001). The more survey waves respondents reported cost-related medication underuse during 1998 to 2004, the higher the probability of being hospitalized in 2006 (adjusted predicted probability of 54\% among respondents reporting cost-related medication underuse in all 4 survey waves compared with 42\% among respondents reporting no underuse, P < 0.001). There was no independent association of cost-related medication underuse with death.

CONCLUSIONS: In this nationally representative cohort, middle-aged and elderly adults with cardiovascular disease who reported cutting back on medication use because of cost were more likely to report being hospitalized over a subsequent 2-year period after they had reported medication underuse. The more extensively respondents reported cost-related underuse over time, the higher their adjusted predicted probability of subsequent hospitalization.
