Delayed medical care and its perceived health impact among US older adults during the COVID-19 pandemic

Background: Medical care delivery has been substantially disrupted during the coronavirus disease 2019 (COVID-19) pandemic, leading to delays in medical care, particularly among older adults. Less is known about how these delays have affected different segments of this population. Understanding the negative health consequences older adults face from delayed care will provide critical insights into the longer-term population health needs following the pandemic. Methods: We used data from a COVID-19 substudy embedded in a nationally representative longitudinal study of older adults, the National Social Life, Health, and Aging Project. Data were collected between September 14, 2020, and January 27, 2021. Two thousand six hundred seventy-two individuals responded to the survey. Using logistic and multinomial logistic regressions, we determined respondent-level characteristics associated with delayed medical care, experiencing a negative impact on physical health from delayed care, and with reporting worsening physical health during the pandemic. Results: Nearly, one-third (32.8%) of older adults reported delayed medical care during the pandemic. Female sex, higher levels of education, greater concerns about the pandemic, and poorer self-rated physical health were associated with delayed medical care. Blacks and those who are 70 and older were less likely to report delayed care. Among those whose care was delayed, 76.5% reported having already recovered delayed care. Nearly one in five (17.6%) reported that delayed care negatively affected their health. Older adults with worse self-rated physical and mental health or who had not fully recovered delayed care were more likely to report perceived negative health impacts from the delay. Regardless of delayed medical care, 10.2% reported worse physical health during the pandemic. Conclusions: One-third of older adults experienced care delays during the pandemic. Despite high rates of care recovery, nearly one in five older adults who experienced delayed care reported being negatively affected. Strategies must be developed to reach these vulnerable patients to increase their healthcare utilization.</p

Social capital predicts accelerometry-measured physical activity among older adults in the U.S.: a cross-sectional study in the National Social Life, Health, and Aging Project

Abstract Background Older adults receive important health benefits from more robust social capital. Yet, the mechanisms behind these associations are not fully understood. Some evidence suggests that higher levels of social capital ultimately affect health through alterations in physical activity (PA), but most of this research has relied on self-reported levels of PA. The aim of this study was to determine whether components of social capital, including social network size and composition as well as the frequency of participation in various social and community activities, were associated with accelerometry-measured PA levels in a nationally representative sample of community-dwelling older adults (≥ 62 years). Methods We conducted a cross-sectional analysis using data from the wrist accelerometry sub-study (n = 738) within Wave 2 of the National Social, Health, and Aging Project (NSHAP), a population-based longitudinal study that collects extensive survey data on the physical, cognitive, and social health of older adults. Participants’ physical activity was measured with a wrist accelerometer worn for 72 consecutive hours. We related seven, self-reported social relationship variables (network size, network proportion friends, and frequencies of socializing with friends and family, visiting with neighbors, attending organized group meetings, attending religious services, and volunteering) to accelerometer-measured PA (mean counts-per-minute) using multivariate linear regression analysis, while adjusting for potential confounders. Results Larger social networks (p = 0.042), higher network proportion friends (p = 0.013), more frequent visiting with neighbors (p = 0.009), and more frequent attendance at organized group meetings (p = 0.035) were associated with higher PA levels after controlling for demographic and health covariates. Volunteering was significant prior to adjusting for covariates. No significant associations were found between frequencies of socializing with friends and relatives or attendance at religious services and PA. Conclusions This study suggests social capital is significantly related to objectively measured PA levels among older adults, and that friendships as well as social participation in groups and with neighbors may be particularly pertinent to PA. These findings expand our understanding of and offer a potential mechanism linking social relationships and overall health among older adults. They also have implications for how we might motivate older adults to be more physically active

Higher baseline resting metabolic rate is associated with 1-year frailty decline among older adults residing in an urban area

Abstract Background Dysregulated energy metabolism is one hypothesized mechanism underlying frailty. Resting energy expenditure, as reflected by resting metabolic rate (RMR), makes up the largest component of total energy expenditure. Prior work relating RMR to frailty has largely been done in cross section with mixed results. We investigated whether and how RMR related to 1-year frailty change while adjusting for body composition. Methods N = 116 urban, predominantly African-American older adults were recruited between 2011 and 2019. One-year frailty phenotype (0–5) was regressed on baseline RMR, frailty phenotype, demographics and body composition (DEXA) in an ordinal logistic regression model. Multimorbidity (Charlson comorbidity scale, polypharmacy) and cognitive function (Montreal Cognitive Assessment) were separately added to the model to assess for change to the RMR-frailty relationship. The model was then stratified by baseline frailty status (non-frail, pre-frail) to explore differential RMR effects across frailty. Results Higher baseline RMR was associated with worse 1-year frailty (odds ratio = 1.006 for each kcal/day, p = 0.001) independent of baseline frailty, demographics, and body composition. Lower fat-free mass (odds ratio = 0.88 per kg mass, p = 0.008) was independently associated with worse 1-year frailty scores. Neither multimorbidity nor cognitive function altered these relationships. The associations between worse 1-year frailty and higher baseline RMR (odds ratio = 1.009, p < 0.001) and lower baseline fat-free mass (odds ratio = 0.81, p = 0.006) were strongest among those who were pre-frail at baseline. Discussion We are among the first to relate RMR to 1-year change in frailty scores. Those with higher baseline RMR and lower fat-free mass had worse 1-year frailty scores, but these relationships were strongest among adults who were pre-frail at baseline. These relationships were not explained by chronic disease or impaired cognition. These results provide new evidence suggesting higher resting energy expenditure is associated with accelerate frailty decline
