Health Literacy and Women's Reproductive Health: A Systematic Review

Background: Health literacy is thought to impact women's reproductive health, yet no comprehensive systematic reviews have been conducted on the topic. Our objective was to systematically identify, investigate, and summarize research on the relationship between health literacy and women's reproductive health knowledge, behaviors, and outcomes

Change in health literacy over a decade in a prospective cohort of community-dwelling older adults

BACKGROUND: Health literacy is often viewed as a static trait in longitudinal studies, which may over or underestimate an individual’s ability to manage one’s health. OBJECTIVES: We sought to examine health literacy over time among older adults using three widely used measures. DESIGN: A prospective cohort study. PARTICIPANTS: Community-dwelling adults ages 55 to 74 at baseline with at least one follow-up visit (N = 656) recruited from one academic internal medicine clinic and six community health centers in Chicago, IL. MEASURES: Health literacy was measured using the Test of Functional Health Literacy in Adults (TOFHLA), Newest Vital Sign (NVS), and Rapid Estimate of Adult Literacy in Medicine (REALM) at baseline and up to three follow-up time points. RESULTS: In unadjusted analyses, significant changes since baseline were found beginning at the second follow-up (mean (M) = 6.0 years, SD = 0.6) for the TOFHLA (M = − 0.9, SD = 0.95, p = 0.049) and the REALM (M = 0.3, SD = 2.5, p = 0.004) and at the last follow-up (M = 8.6 years, SD = 0.5) for the NVS (M = − 0.2, SD = 1.4, p = 0.02). There were non-linear effects of baseline age on TOFHLA and NVS scores over time (piecewise cubic spline p = 0.01 and p < 0.001, respectively) and no effect on REALM scores (B = 0.02, 95% CI − 0.01 to 0.04, p = 0.17) using multivariable mixed-effects linear regression models, controlling for race, education, income, and comorbidity. CONCLUSION: We found a negative relationship between age and health literacy over time as measured by the TOFHLA and NVS. Health literacy barriers appear to be more prevalent among individuals in later life, when self-care demands are similarly increasing. Clinicians might consider strategies to assess and respond to limited health literacy, particularly among patients 70 and older. REALM performance remained stable over 10 years of follow-up. This questions whether health literacy tools measure the same attribute. Prospective health literacy studies should carefully consider what measures to use, depending on their objective

Health literacy and 30-day hospital readmission after acute myocardial infarction

ObjectiveTo assess the validity of a predictive model of health literacy, and to examine the relationship between derived health literacy estimates and 30-day hospital readmissions for acute myocardial infarction (AMI).DesignRetrospective cohort study.Setting and participantsA National Institute of Aging (NIA) study cohort of 696 adult, English-speaking primary care patients, aged 55–74 years, was used to assess the validity of derived health literacy estimates. Claims from 7733 Medicare beneficiaries hospitalised for AMI in 2008 in North Carolina and Illinois were used to investigate the association between health literacy estimates and 30-day hospital readmissions.MeasuresThe NIA cohort was administered 3 common health literacy assessments (Newest Vital Sign, Test of Functional Health Literacy in Adults, and Rapid Estimate of Adult Literacy in Medicine). Health literacy estimates at the census block group level were derived via a predictive model. 30-day readmissions were measured from Medicare claims data using a validated algorithm.ResultsFair agreement was found between derived estimates and in-person literacy assessments (Pearson Correlation coefficients: 0.38–0.51; κ scores: 0.38–0.40). Medicare enrollees with above basic literacy according to derived health literacy estimates had an 18% lower risk of a 30-day readmission (RR=0.82, 95% CI 0.73 to 0.92) and 21% lower incidence rate of 30-day readmission (IRR=0.79, 95% CI 0.68 to 0.87) than patients with basic or below basic literacy. After adjusting for demographic and clinical characteristics, the risk of 30-day readmission was 12% lower (p=0.03), and the incidence rate 16% lower (p<0.01) for patients with above basic literacy.ConclusionsHealth literacy, as measured by a predictive model, was found to be a significant, independent predictor of 30-day readmissions. As a modifiable risk factor with evidence-based solutions, health literacy should be considered in readmission reduction efforts

Literacy disparities in patient access and health-related use of Internet and mobile technologies

Age and race-related disparities in technology use have been well documented, but less is known about how health literacy influences technology access and use

Psychosocial Determinants of Self-Management Behaviors and Health Outcomes Among Older Adults

Chronic conditions have emerged as the primary cause of morbidity and mortality in the United States, and the prevalence of individuals contending with multiple chronic conditions, the co-occurrence of two or more chronic conditions, is increasing. Engaging in self-management behaviors is a core mechanism to promote health outcomes and prevent chronic disease complications. A sizable body of evidence has identified a number of psychosocial determinants of proper chronic disease self-management and health outcomes; despite this evidence, there has been slow progress in addressing these psychosocial factors to support proper self-management behaviors. This may be due to a lack of attention to the requisite skills individuals must employ to engage in self-care behaviors, and a lack of appreciation for the role which external contextual factors exert in health management. Therefore, as part of this dissertation I conducted three secondary data analyses with two National Institutes of Health cohort studies of older adults to investigate two understudied psychosocial factors, tangible social support and a daily routine, and their relation to older adults’ self-management behaviors and health outcomes. At the individual level I found that greater levels of daily routine were associated with better health status, but not urgent health care utilization. At the interpersonal level, the analyses related to social support underscored its multidimensional and complex nature. Contrary to my hypothesis, the second study observed a negative association between the frequency of functional support and adherence to asthma medications, while the third study found that unmet tangible support needs were associated with worse health status and greater urgent healthcare utilization. Differences in measurement between the two studies suggest that it is important to first isolate a need for tangible assistance in managing one’s health, and then examine perceptions related to the support’s availability and adequacy. In conclusion, as we seek to promote healthy aging, findings from this dissertation shed light on two psychosocial factors, a daily routine and unmet tangible social support needs, which could be leveraged, but also suggests that they must be acted on with simultaneous systemic changes

The Association of Health Literacy with Illness and Medication Beliefs among Patients with Chronic Obstructive Pulmonary Disease.

Low health literacy is associated with low adherence to self-management in many chronic diseases. Additionally, health beliefs are thought to be determinants of self-management behaviors. In this study we sought to determine the association, if any, of health literacy and health beliefs among elderly individuals with COPD.We enrolled a cohort of patients with COPD from two academic urban settings in New York, NY and Chicago, IL. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Using the framework of the Self-Regulation Model, illness and medication beliefs were measured with the Brief Illness Perception Questionnaire (B-IPQ) and Beliefs about Medications Questionnaire (BMQ). Unadjusted analyses, with corresponding Cohen's d effect sizes, and multiple logistic regression were used to assess the relationships between HL and illness and medication beliefs.We enrolled 235 participants, 29% of whom had low health literacy. Patients with low health literacy were more likely to belong to a racial minority group (p<0.001), not be married (p = 0.006), and to have lower income (p<0.001) or education (p<0.001). In unadjusted analyses, patients with low health literacy were less likely to believe they will always have COPD (p = 0.003, Cohen's d = 0.42), and were more likely to be concerned about their illness ((p = 0.04, Cohen's d = 0.17). In analyses adjusted for sociodemographic factors and other health beliefs, patients with low health literacy were less likely to believe that they will always have COPD (odds ratio [OR]: 0.78, 95% confidence interval [CI]: 0.65-0.94). In addition, the association of low health literacy with expressed concern about medications remained significant (OR: 1.20, 95% CI: 1.05-1.37) though the association of low health literacy with belief in the necessity of medications was no longer significant (OR: 0.92, 95% CI: 0.82-1.04).In this cohort of urban individuals with COPD, low health literacy was prevalent, and associated with illness beliefs that predict decreased adherence. Our results suggest that targeted strategies to address low health literacy and related illness and medications beliefs might improve COPD medication adherence and other self-management behaviors

Health Literacy and Women's Reproductive Health: A Systematic Review

Background: Health literacy is thought to impact women's reproductive health, yet no comprehensive systematic reviews have been conducted on the topic. Our objective was to systematically identify, investigate, and summarize research on the relationship between health literacy and women's reproductive health knowledge, behaviors, and outcomes. Methods: PRISMA guidelines were used to guide this review. English language, peer-reviewed research articles indexed in MEDLINE as of February 2015 were searched, along with study results posted on Clinicaltrials.gov. Articles were included if they (1) described original data-driven research conducted in developed countries, (2) were published in a peer-reviewed journal, (3) measured health literacy using a validated assessment, (4) reported on the relationship between health literacy and reproductive health outcomes, related knowledge, or behaviors, and (5) consisted of a study population that included reproductive age women. Results: A total of 34 articles met eligibility criteria and were included in this review. Data were abstracted from articles by two study authors using a standardized form. Abstracted data were then reviewed and summarized in table format. Overall, health literacy was associated with reproductive health knowledge across a spectrum of topics. It was also related to certain health behaviors, such as prenatal vitamin use and breastfeeding. Its relationship with other reproductive behaviors and outcomes remains unclear. Conclusions: Health literacy plays an important role in reproductive knowledge and may impact behaviors and outcomes. While further research is necessary, healthcare providers should utilize health literacy best practices now to promote high-quality care for patients

Long-term impact of the COVID-19 pandemic on self-management of chronic conditions among high-risk adults in the USA: protocol for the C3 observational cohort study

Introduction COVID-19 is an unprecedented public health threat in modern times, especially for older adults or those with chronic illness. Beyond the threat of infection, the pandemic may also have longer-term impacts on mental and physical health. The COVID-19 &amp; Chronic Conditions (‘C3’) study offers a unique opportunity to assess psychosocial and health/healthcare trajectories over 5 years among a diverse cohort of adults with comorbidities well-characterised from before the pandemic, at its onset, through multiple surges, vaccine rollouts and through the gradual easing of restrictions as society slowly returns to ‘normal’.Methods and analysis The C3 study is an extension of an ongoing longitudinal cohort study of ‘high-risk’ adults (aged 23–88 at baseline) with one or more chronic medical conditions during the COVID-19 pandemic. Five active studies with uniform data collection prior to COVID-19 were leveraged to establish the C3 cohort; 673 adults in Chicago were interviewed during the first week of the outbreak. The C3 cohort has since expanded to include 1044 participants across eight survey waves (T1–T8). Four additional survey waves (T9–T12) will be conducted via telephone interviews spaced 1 year apart and supplemented by electronic health record and pharmacy fill data, for a total of 5 years of data post pandemic onset. Measurement will include COVID-19-related attitudes/behaviours, mental health, social behaviour, lifestyle/health behaviours, healthcare use, chronic disease self-management and health outcomes. Mental health trajectories and associations with health behaviours/outcomes will be examined in a series of latent group and mixed effects modelling, while also examining mediating and moderating factors.Ethics and dissemination This study was approved by Northwestern University’s Feinberg School of Medicine Institutional Review Board (STU00215360). Results will be published in international peer-reviewed journals and summaries will be provided to the funders of the study
