Wearable Activity Tracker Use and Physical Activity Among Informal Caregivers in the United States: Quantitative Study

Background: With an increase in aging population and chronic medical conditions in the United States, the role of informal caregivers has become paramount as they engage in the care of their loved ones. Mounting evidence suggests that such responsibilities place substantial burden on informal caregivers and can negatively impact their health. New wearable health and activity trackers (wearables) are increasingly being used to facilitate and monitor healthy behaviors and to improve health outcomes. Although prior studies have examined the efficacy of wearables in improving health and well-being in the general population, little is known about their benefits among informal caregivers. Objective: This study aimed to examine the association between use of wearables and levels of physical activity (PA) among informal caregivers in the United States. Methods: We used data from the National Cancer Institute’s Health Information National Trends Survey 5 (cycle 3, 2019 and cycle 4, 2020) for a nationally representative sample of 1273 community-dwelling informal caregivers—aged ≥18 years, 60% (757/1273) female, 75.7% (990/1273) had some college or more in education, and 67.3% (885/1273) had ≥1 chronic medical condition—in the United States. Using jackknife replicate weights, a multivariable logistic regression was fit to assess an independent association between the use of wearables and a binary outcome: meeting or not meeting the current World Health Organization’s recommendation of PA for adults (≥150 minutes of at least moderate-intensity PA per week). Results: More than one-third (466/1273, 37.8%) of the informal caregivers met the recommendations for adult PA. However, those who reported using wearables (390/1273, 31.7%) had slightly higher odds of meeting PA recommendations (adjusted odds ratios 1.1, 95% CI 1.04-1.77; P=.04) compared with those who did not use wearables. Conclusions: The results demonstrated a positive association between the use of wearables and levels of PA among informal caregivers in the United States. Therefore, efforts to incorporate wearable technology into the development of health-promoting programs or interventions for informal caregivers could potentially improve their health and well-being. However, any such effort should address the disparities in access to innovative digital technologies, including wearables, to promote health equity. Future longitudinal studies are required to further support the current findings of this study

Hospital Value-Based Payment Programs and Disparity In the United States: A Review of Current Evidence and Future Perspectives

Beginning in the early 2010s, an array of Value-Based Purchasing (VBP) programs has been developed in the United States (U.S.) to contain costs and improve health care quality. Despite documented successes in these efforts in some instances, there have been growing concerns about the programs\u27 unintended consequences for health care disparities due to their built-in biases against health care organizations that serve a disproportionate share of disadvantaged patient populations. We explore the effects of three Medicare hospital VBP programs on health and health care disparities in the U.S. by reviewing their designs, implementation history, and evidence on health care disparities. The available empirical evidence thus far suggests varied impacts of hospital VBP programs on health care disparities. Most of the reviewed studies in this paper demonstrate that hospital VBP programs have the tendency to exacerbate health care disparities, while a few others found evidence of little or no worsening impacts on disparities. We discuss several policy options and recommendations which include various reform approaches and specific programs ranging from those addressing upstream structural barriers to health care access, to health care delivery strategies that target service utilization and health outcomes of vulnerable populations under the VBP programs. Future studies are needed to produce more explicit, conclusive, and consistent evidence on the impacts of hospital VBP programs on disparities

Sleep, Health, and Wellbeing Among Middle-Aged and Older Adults: Impact of Insomnia Symptoms on Incident Heart Failure, Cognitive Performance, and All-Cause Mortality

In this three-paper dissertation, we used longitudinal data from the Health and Retirement Study (HRS) to investigate prospective associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, non-restorative sleep) and incident heart failure (HF), cognitive impairmentno dementia (CIND), and all-cause mortality among middle-aged and older adults (aged 50 years). In each study, we implemented a marginal structural modeling approach to generate the average causal effects of insomnia symptoms, while taking into account time-dependent biological, psycho-cognitive, behavioral, and lifestyle factors, and adjustments for selection bias.The first paper employed data from the 2002 through 2018 waves of HRS, with a sample of 12,761 individuals who were free from HF at baseline in 2002. Marginal structural discrete-time survival analyses were conducted. During the 16-year follow-up, 1,730 sample respondents had incident HF. Individuals experiencing one (hazard ratio [HR]=1.22; 95% CI: 1.081.38), two (HR=1.45; 95% CI: 1.211.72), three (HR=1.66; 95% CI: 1.372.02), or four (HR=1.80; 95% CI: 1.252.59) insomnia symptoms had a higher hazard of incident HF than asymptomatic respondents. In the second paper, we used data from a cohort of 14,530 cognitively healthy HRS respondents (2004 baseline) and followed participants for 12 years (through 2016). We evaluated cognitive performance biennially (CIND vs. normal) and then employed marginal structural generalized estimating equations. The association between insomnia symptoms and CIND varied with respondents age. For those 50 to 64 years old, experiencing two (odds ratio [OR]=1.38; 95% CI: 1.191.63) and three or four (OR=1.39; 95% CI: 1.161.65) insomnia symptoms were associated with higher risks of CIND compared to being symptom-free. For those 65 to 74 years old, experiencing three or four insomnia symptoms was significantly associated with the risk of CIND (OR=1.31; 95% CI: 1.081.58). Among respondents aged 75 or older, insomnia symptoms were not associated with CIND. In the third and final paper, we obtained data from 2004 (baseline) through 2018 survey waves of HRS for a sample of 15,511 individuals. During 14 years of follow-up, 5,878 respondents (31.9%) died. We performed marginal structural discrete-time survival analyses. Respondents who experienced one (HR=1.11; 95% CI: 1.031.20), two (HR=1.12; 95% CI: 1.011.23), three (HR=1.15; 95% CI: 1.051.27), or four (HR=1.32; 95% CI: 1.121.56) insomnia symptoms had on average a higher hazard of all-cause mortality, compared to those who were symptom-free. Our findings indicate that insomnia symptoms are significantly associated with incident HF and all-cause mortality among middle-aged and older adults regardless of age category and that the symptoms could negatively impact cognition by increasing the risks of CIND among middle-aged and, to a lesser extent, older adults. Expanding public health awareness about insomnia and increasing screening for insomnia symptoms in at-risk populations can be an essential prevention strategy. Future studies could investigate complex mechanisms linking insomnia symptoms and these adverse health outcomes

Emergency department and inpatient utilization among U.S. older adults with multiple chronic conditions: A post-reform update

Background: The Affordable Care Act (ACA) was enacted to enhance access to care primarily among nonelderly and low-income populations; however, several provisions addressed key determinants of emergency department (ED) and inpatient visits among Medicare beneficiaries over age 65 years. We take stock of the overall changes in these visits among older Medicare beneficiaries, focusing on those with multiple chronic conditions (MCCs), and provide a nationally representative post-reform update. Methods: We analyzed a sample of 32,919 older adults (65+) on Medicare from the 2006-2015 Medical Expenditure Panel Survey (MEPS). Using a survey-weighted two-part model, we examined changes in ED visits, inpatient visits, and length of stay (LOS) by MCC status, before (2006-2010), during (2011-2013), and after the ACA (2014-2015). Results: Prior to the ACA, 18.1% of Medicare older adults had ≥1 ED visit, whereas 17.1% had ≥1 inpatient visits, with an average of 5.1 nights/visit. Following ACA reforms, among those with 2+ chronic conditions, the rate of ever having an ED visit increased by 4.3 percentage points [95% confidence intervals [CI]: 2.5, 6.1, p \u3c 0.01], whereas the rate of inpatient visits decreased by 1.4 percentage points [95%CI: - 2.9, 0.2, p \u3c 0.1], after multivariable adjustment. Conclusions: We found sizable increases in ED visits and nontrivial decreases in inpatient visits among older Medicare beneficiaries with MCCs, underscoring the continuing need for improving access to and quality of care among older adults with MCCs to decrease reliance on the ED and reduce preventable hospitalizations

Food Insecurity and Influenza and Pneumonia Vaccines Uptake Among Community-Dwelling Older Adults in the United States

Influenza and pneumonia vaccines can reduce morbidities and mortality associated with infectious diseases among older adults. Food security, good nutrition, and high-quality diets are critical for the wellbeing of older adults. However, little is known about the relationship between food insecurity and use of preventive health services, such as influenza and pneumonia vaccinations, among older adults. In this study, we analyzed data on 40,555 adults aged ≥ 65 years from the 2014–2018 National Health Interview Survey in the United States. Through multiple hierarchical logistic regression models, we investigated the associations between food insecurity and influenza and pneumonia vaccines uptake in this population. We found that, during 2014–2018, about 12.6 million (5.3%) adults aged ≥ 65 years lived in food-insecure households in the United States. Of those, 60.6% reported getting an influenza vaccine in the past 12 months, and 54.2% reported ever getting a pneumonia vaccine. Compared to food-secure older adults, food-insecure individuals were not significantly different in terms of influenza vaccine uptake. However, they were 25% less likely to have ever gotten a pneumonia vaccine (adjusted odds ratio = 0.75, 95% CI 0.65–0.86, P \u3c.001). Efforts should be made to develop strategies to improve immunization rates among food-insecure older adults. Healthcare providers could routinely assess their vaccination status and screen them for food insecurity. Also, community level screening and intervention programs should target food-insecure older adults, who often face structural disadvantages. Future studies could explore and identify the underlying predictive factors contributing to low pneumonia vaccination rates among food-insecure older adults

Longitudinal associations between insomnia symptoms and all-cause mortality among middle-aged and older adults: a population-based cohort study

To date, there is no scientific consensus on whether insomnia symptoms increase mortality risk. We investigated longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, and nonrestorative sleep) and all-cause mortality among middle-aged and older adults during 14 years of follow-up. Data were obtained from 2004 through 2018 survey waves of the Health and Retirement Study in the United States for a population-representative sample of 15 511 respondents who were ≥50 years old in 2004. Respondents were interviewed biennially and followed through the end of the 2018 survey wave for the outcome. Marginal structural discrete-time survival analyses were employed to account for time-varying confounding and selection bias. Of the 15 511 cohort respondents (mean [±SD] age at baseline, 63.7 [±10.2] years; 56.0% females), 5878 (31.9%) died during follow-up. At baseline (2004), 41.6% reported experiencing at least one insomnia symptom. Respondents who experienced one (HR = 1.11; 95% CI: 1.03-1.20), two (HR = 1.12; 95% CI: 1.01-1.23), three (HR = 1.15; 95% CI: 1.05-1.27), or four (HR = 1.32; 95% CI: 1.12-1.56) insomnia symptoms had on average a higher hazard of all-cause mortality, compared to those who were symptom-free. For each insomnia symptom, respondents who experienced difficulty initiating sleep (HR = 1.12; 95% CI: 1.02-1.22), early-morning awakening (HR = 1.09; 95% CI: 1.01-1.18), and nonrestorative sleep (HR = 1.17; 95% CI: 1.09-1.26), had a higher hazard of all-cause mortality compared to those not experiencing the symptom. The findings demonstrate significant associations between insomnia symptoms and all-cause mortality, both on a cumulative scale and independently, except for difficulty maintaining sleep. Further research should investigate the underlying mechanisms linking insomnia symptoms and mortality

Insomnia symptoms and incident heart failure: A population-based cohort study

Aims: Heart failure (HF) is an ongoing epidemic and a serious clinical and public health issue. Currently, little is known about prospective associations between insomnia symptoms and HF incidence. We investigated the longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, non-restorative sleep) and incident HF. Methods and results: Data were obtained from the Health and Retirement Study in the US for a population-representative sample of 12,761 middle-aged and older adults (age ≥ 50 years; mean [SD] age, 66.7 [9.4] years; 57.7% females) who were free from HF at baseline in 2002. Respondents were followed for 16 years for incident HF. We employed marginal structural discrete-time survival analyses to adjust for potential time-varying biological, psycho-cognitive, and behavioral factors and to account for bias due to differential loss to follow-up. At baseline, 38.4% of the respondents reported experiencing at least one insomnia symptom. During the 16-year follow-up, 1,730 respondents developed incident HF. Respondents experiencing one (hazard ratio [HR]=1.22; 95% CI: 1.08-1.38), two (HR=1.45; 95% CI: 1.21-1.72), three (HR=1.66; 95% CI: 1.37-2.02), or four (HR=1.80; 95% CI: 1.25-2.59) insomnia symptoms had a higher hazard of incident HF than asymptomatic respondents. Respondents that had trouble initiating sleep (HR=1.17; 95%CI: 1.01-1.36), maintaining sleep (HR=1.14; 95% CI: 1.01-1.28), early-morning awakening (HR=1.20; 95% CI: 1.02-1.43), or non-restorative sleep (HR=1.25; 95% CI: 1.06-1.46) had a higher hazard of incident HF than asymptomatic respondents. Conclusion: Insomnia symptoms, both cumulatively and individually, are associated with incident HF. Public health awareness and screening for insomnia symptoms in at-risk populations should be encouraged to reduce HF incidence

Longitudinal associations between time-varying insomnia symptoms and all-cause health care services utilization among middle-aged and older adults in the United States

Objective: To examine longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakenings, and nonrestorative sleep) and all-cause health care services utilization (HSU), including overnight hospital stays, nursing home stays, and home health care services among middle-aged and older adults. Data Sources: The Health and Retirement Study (HRS), a nationwide, population-representative survey of primarily middle-aged and older adults in the United States. Study Design: This study is an analysis of prospective data from the HRS for a cohort of 13,168 adults (aged ≥50 years; females = 57.7%). Study participants were followed for 16 years. This study focuses on the associations between time-varying insomnia symptoms, both cumulatively and independently, and repeated HSUs. A marginal structural modeling approach was used to capture time-varying biological, psycho-cognitive, and behavioral health factors, and to adjust for selection bias such as differential loss to follow-up. Generalized estimating equations were employed to compute average marginal effects and their 95% confidence intervals. Data Collection/Extraction Methods: We extracted longitudinal data from 2002 through 2018 waves of the HRS. Principal Findings: Experiencing higher numbers of insomnia symptoms on a cumulative scale was associated with higher probabilities of HSU. For instance, the likelihood of overnight hospital stays for individuals reporting one symptom increased from 4.7 percentage points on average (95% CI: 3.7–5.6, p \u3c 0.001), to 13.9 percentage points (95% CI: 10.3–17.5, p \u3c 0.001) for those reporting four symptoms, relative to individuals experiencing no insomnia symptoms. Further, experiencing each of difficulty initiating and maintaining sleep, and nonrestorative sleep, as standalone symptoms, was associated with a higher likelihood of HSU when compared to those not experiencing the symptoms. Conclusions: The results demonstrate the potential consequences and adverse impacts of insomnia symptoms on HSU among middle-aged and older adults. Future investigations should focus on the underlying causes and health systems pathways linking insomnia symptoms to HSU

Access to Personal Health Records and Screening for Breast and Cervical Cancer Among Women with a Family History of Cancer

It is essential for at-risk women to be screened for breast and cervical cancer in a timely manner. Despite a growing interest in the role of health information technology including personal health records (PHRs) to improve quality and outcomes in health care, less is known about the effectiveness of PHRs to promote breast and cervical cancer screening among women with a family history of cancer (FHC). We examined the association between access to PHRs and the use of a recommended mammography and a Pap smear testing among women with a FHC using data from the 2015 Health Information National Trends Survey (HINTS 4-cycle 4) and the 2016 Area Health Resource Files. The study sample was comprised of 1250 women aged 20–75 years with a FHC, a subsample of 3677 survey respondents. Of the 1250 women, 64.96% received a mammogram, and 75.44% underwent a Pap testing. Among women with a FHC, there was a significant and positive association between access to PHRs and the receipt of a mammogram (adjusted odds ratio (aOR) 4.20; 95% CI, 2.23–7.94; p \u3c.001) and a Pap testing (aOR 3.13; 95% CI, 1.56–6.28; p \u3c.01). Our findings suggest that at-risk women can benefit from greater access to PHRs. Policymakers should consider incentivizing providers and healthcare organizations who provide access to PHRs to their patients as well as developing programs that can help improve access to PHRs among at-risk women

Methamphetamine-Induced Wakefulness and Sleep Management: A Qualitative Analysis of Online Narratives

While much attention has been given to methamphetamine’s wake-promoting properties and the concept of using methamphetamine to increase energy, little is known about the ways people who use methamphetamine manage their use to pursue their functional goals or the challenges they encounter doing so. This qualitative study explores the experiences of people who used methamphetamine to manage wakefulness and reduce sleep as a means to achieve functional goals. We conducted a grounded theory analysis of 202 anonymous letters submitted to an online forum. Five themes emerged from this process: (1) Using methamphetamine to extend wakefulness and reduce the need for sleep; (2) Losing control over wakefulness and the need for sleep; (3) Managing wakefulness and the need for sleep while on methamphetamine; (4) Getting caught in a cycle of wakefulness and sleep; and (5) Sleep disruptions even after ceasing methamphetamine use. Participants believed methamphetamine was critical to meeting their functional goals, and they went to great lengths to try to manage the substance’s ill effects. Thus, clients in treatment for methamphetamine use disorder may benefit from interventions addressing their underlying motivations and perceived associations between methamphetamine and meeting functional goals
