ABCs or 123s? The independent contributions of literacy and numeracy skills on health task performance among older adults

AbstractObjectiveTo investigate the relationship between literacy and numeracy and their association with health task performance.MethodsOlder adults (n=304) completed commonly used measures of literacy and numeracy. Single factor literacy and numeracy scores were calculated and used to predict performance on an established set of health self-management tasks, including: (i) responding to spoken information; (ii) comprehension of print and (iii) multimedia information; and (iv) organizing and dosing medication. Total and sub-scale scores were calculated.ResultsLiteracy and numeracy measures were highly correlated (rs=0.68; ps<0.001). In multivariable models adjusted for age, gender, race, education, and comorbidity, lower literacy (β=0.44, p<0.001) and numeracy (β=0.44, p<0.001) were independently associated with worse overall task performance and all sub-scales (literacy range, β=0.23–0.45, ps<0.001; numeracy range, β=0.31–0.41, ps<0.001). Multivariable analyses with both constructs entered explained more variance in overall health task performance compared with separate literacy and numeracy models (8.2% and 10% respectively, ps<0.001).ConclusionLiteracy and numeracy were highly correlated, but independent predictors of health task performance. These skill sets are complementary and both are important for health self-management.Practice implicationsSelf-management interventions may be more effective if they consider both literacy and numeracy skills rather than focusing on one specific ability

Health literacy, health status, and healthcare utilization of Taiwanese adults: results from a national survey

Abstract Background Low health literacy is considered a worldwide health threat. The purpose of this study is to assess the prevalence and socio-demographic covariates of low health literacy in Taiwanese adults and to investigate the relationships between health literacy and health status and health care utilization. Methods A national survey of 1493 adults was conducted in 2008. Health literacy was measured using the Mandarin Health Literacy Scale. Health status was measured based on self-rated physical and mental health. Health care utilization was measured based on self-reported outpatient clinic visits, emergency room visits, and hospitalizations. Results Approximately thirty percent of adults were found to have low (inadequate or marginal) health literacy. They tended to be older, have fewer years of schooling, lower household income, and reside in less populated areas. Inadequate health literacy was associated with poorer mental health (OR, 0.57; 95% CI, 0.35-0.91). No association was found between health literacy and health care utilization even after adjusting for other covariates. Conclusions Low (inadequate and marginal) health literacy is prevalent in Taiwan. High prevalence of low health literacy is not necessarily indicative of the need for interventions. Systematic efforts to evaluate the impact of low health literacy on health outcomes in other countries would help to illuminate features of health care delivery and financing systems that may mitigate the adverse health effects of low health literacy.http://deepblue.lib.umich.edu/bitstream/2027.42/78252/1/1471-2458-10-614.xmlhttp://deepblue.lib.umich.edu/bitstream/2027.42/78252/2/1471-2458-10-614.pdfPeer Reviewe

On a classical spectral optimization problem in linear elasticity

We consider a classical shape optimization problem for the eigenvalues of elliptic operators with homogeneous boundary conditions on domains in the $N$-dimensional Euclidean space. We survey recent results concerning the analytic dependence of the elementary symmetric functions of the eigenvalues upon domain perturbation and the role of balls as critical points of such functions subject to volume constraint. Our discussion concerns Dirichlet and buckling-type problems for polyharmonic operators, the Neumann and the intermediate problems for the biharmonic operator, the Lam\'{e} and the Reissner-Mindlin systems.Comment: To appear in the proceedings of the workshop `New Trends in Shape Optimization', Friedrich-Alexander Universit\"{a}t Erlangen-Nuremberg, 23-27 September 201

Older Adult Preferences of Mobile Application Functionality Supporting Medication Self-Management

Health systems and insurers alike are increasingly interested in leveraging mHealth (mobile health) tools to support patient health-related behaviors including medication adherence. However, these tools are not widely used by older patients. This study explores patient preferences for functionality in a smartphone application (app) that supports medication self-management among older adults with multiple chronic conditions. We conducted six discussion groups in Chicago, Miami, and Denver (N = 46). English-speaking older adults (55 and older) who owned smartphones and took five or more prescription medicines were invited to participate. Discussions covered familiarity with and use of current apps and challenges with taking multidrug regimens. Participants reviewed a range of possible mobile app functions and were asked to give feedback regarding the acceptability and desirability of each to support medication management. Very few participants (n = 3) reported current use of a mobile app for medication support, although all were receptive. Challenges to medication use were forgetfulness, fear of adverse events, and managing medication information from multiple sources. Desired features included (1) a list and consolidated schedule of medications, (2) identification and warning of unsafemedication interactions, (3) reminder alerts to take medicine, and (4) the ability record when medications were taken. Features relating to refill ordering, pharmacy information, and comparing costs for medication were not considered to be as important for an app

Aging and functional health literacy: a systematic review and meta-analysis

OBJECTIVES: To review the evidence on the association between age and limited health literacy, overall and by health literacy test, and to investigate the mediating role of cognitive function. METHODS: The Embase, MEDLINE®, and PsycINFO databases were searched. Eligible studies were conducted in any country or language, included participants aged ≥50 years, presented a measure of association between age and health literacy, and were published through September 2013. RESULTS: Seventy analyses in 60 studies were included in the systematic review; 29 of these were included in the meta-analysis. Older age was strongly associated with limited health literacy in analyses that measured health literacy as reading comprehension, reasoning, and numeracy skills (random effects OR=4.20; 95% CI: 3.13-5.64). By contrast, older age was weakly associated with limited health literacy in studies that measured health literacy as medical vocabulary (random effects OR=1.19; 95% CI: 1.03-1.37). Evidence on the mediating role of cognitive function was limited. DISCUSSION: Health literacy tests that utilize a range of fluid cognitive abilities and mirror everyday health tasks frequently observe skill limitations among older adults. Vocabulary-based health literacy skills appear more stable with age. Researchers should select measurement tests wisely when assessing health literacy of older adults

Health Literacy and Moderate to Vigorous Physical Activity During Aging, 2004-2013

INTRODUCTION: Health literacy (the ability to read and understand health information) may help to support sustained participation in moderate to vigorous physical activity (MVPA) during aging; this relationship has never been examined longitudinally. This study aimed to investigate the relationship between health literacy and participation in weekly MVPA over an 8-year period among older adults. METHODS: Data were from interviews with 4,345 adults aged 52-79 years in the English Longitudinal Study of Ageing from 2004/2005 to 2012/2013, analyzed in 2015. Health literacy was assessed in 2004/2005 as reading comprehension of a medicine label, defined as "low" (≤2/4 items correct); "medium" (3/4); and "high" (4/4). The outcome was maintaining weekly MVPA at all of five time points from 2004/2005 to 2012/2013. A population-weighted logistic regression model was adjusted for sociodemographic, physical health, and cognitive (memory and verbal fluency) covariates. RESULTS: Overall, 72% (3,128/4,345) of the sample had high health literacy; 18% (797/4,345) had medium health literacy; and 10% (420/4,345) had low health literacy. Of those with high health literacy, 59% (1,840/3,128) consistently reported weekly participation in MVPA, compared with 33% (138/420) of those with low health literacy (AOR=1.37, 95% CI=1.04, 1.80). Better memory was weakly positively associated with long-term MVPA (AOR=1.03, 95% CI=1.00, 1.05, per point increase out of 24), as was better verbal fluency (AOR=1.05, 95% CI=1.01, 1.09, per point increase out of 9). CONCLUSIONS: High health literacy and good cognitive function are independently associated with participation in weekly MVPA over an 8-year period during aging

Cognitive Function and Health Literacy Decline in a Cohort of Aging English Adults.

BACKGROUND Low health literacy is common among aging patients and is a risk factor for morbidity and mortality. We aimed to describe health literacy decline during aging and to investigate the roles of cognitive function and decline in determining health literacy decline. METHODS Data were from 5,256 non-cognitively impaired adults aged ≥ 52 years in the English Longitudinal Study of Ageing. Health literacy was assessed using a four-item reading comprehension assessment of a fictitious medicine label, and cognitive function was assessed in a battery administered in-person at baseline (2004–2005) and at follow-up (2010–2011). RESULTS Overall, 19.6 % (1,032/5,256) of participants declined in health literacy score over the follow-up. Among adults aged ≥ 80 years at baseline, this proportion was 38.2 % (102/267), compared to 14.8 % (78/526) among adults aged 52–54 years (OR = 3.21; 95 % CI: 2.26–4.57). Other sociodemographic predictors of health literacy decline were: male sex (OR = 1.20; 95 % CI: 1.04–1.38), non-white ethnicity (OR = 2.42; 95 % CI: 1.51–3.89), low educational attainment (OR = 1.58; 95 % CI: 1.29–1.95 for no qualifications vs. degree education), and low occupational class (OR = 1.67; 95 % CI: 1.39–2.01 for routine vs. managerial occupations). Higher baseline cognitive function scores protected against health literacy decline, while cognitive decline (yes vs. no) predicted decline in health literacy score (OR = 1.59; 95 % CI: 1.35–1.87 for memory decline and OR = 1.56; 95 % CI: 1.32–1.85 for executive function decline). CONCLUSIONS Health literacy decline appeared to increase with age, and was associated with even subtle cognitive decline in older non-impaired adults. Striking social inequalities were evident, whereby men and those from minority and deprived backgrounds were particularly vulnerable to literacy decline. Health practitioners must be able to recognize limited health literacy to ensure that clinical demands match the literacy skills of diverse patients

Using appreciative inquiry as a framework to enhance the patient experience

The following case depicts the journey of a non-profit hospital in an under-served community and its attempts to turn around suffering patient experience. The Hospital turned to the theories of Appreciative Inquiry and the power of a strengths-based approach to create a framework to support the patient experience initiatives. Hospital leadership led the formation of a Patient Experience Team to implement ten initiatives in order increase the top box score in the domain of willingness to recommend the hospital, as that was selected as a global measure of success for the overall improvement project

Electric-field controlled spin reversal in a quantum dot with ferromagnetic contacts

Manipulation of the spin-states of a quantum dot by purely electrical means is a highly desirable property of fundamental importance for the development of spintronic devices such as spin-filters, spin-transistors and single-spin memory as well as for solid-state qubits. An electrically gated quantum dot in the Coulomb blockade regime can be tuned to hold a single unpaired spin-1/2, which is routinely spin-polarized by an applied magnetic field. Using ferromagnetic electrodes, however, the properties of the quantum dot become directly spin-dependent and it has been demonstrated that the ferromagnetic electrodes induce a local exchange-field which polarizes the localized spin in the absence of any external fields. Here we report on the experimental realization of this tunneling-induced spin-splitting in a carbon nanotube quantum dot coupled to ferromagnetic nickel-electrodes. We study the intermediate coupling regime in which single-electron states remain well defined, but with sufficiently good tunnel-contacts to give rise to a sizable exchange-field. Since charge transport in this regime is dominated by the Kondo-effect, we can utilize this sharp many-body resonance to read off the local spin-polarization from the measured bias-spectroscopy. We show that the exchange-field can be compensated by an external magnetic field, thus restoring a zero-bias Kondo-resonance, and we demonstrate that the exchange-field itself, and hence the local spin-polarization, can be tuned and reversed merely by tuning the gate-voltage. This demonstrates a very direct electrical control over the spin-state of a quantum dot which, in contrast to an applied magnetic field, allows for rapid spin-reversal with a very localized addressing.Comment: 19 pages, 11 figure
