Relationship between child health literacy and body mass index in overweight children

Objective

To test the relationship between child health literacy and body mass index (BMI) Z-score in overweight children.

Methods

Cross-sectional survey of overweight children and parents. Parent and child health literacy was measured by the Short Test of Functional Health Literacy (STOFHLA). Linear regression tested for predictors of childhood BMI Z-score, adjusting for confounders.

Results

Of 171 total children, 107 (62%) participated, of whom 78 (73%) had complete data for analysis. Mean child BMI Z-score (SD) was 2.3 (0.40); median child age (interquartile range) was 11.5 (10–16); 53% were female; 80% were Medicaid recipients. Mean child STOFHLA was 22.9 (9.0); mean parental STOFHLA was 29.1 (8.6). Child STOFHLA correlated negatively with BMI Z-score (r = −0.37, p = 0.0009) and positively with child eating self-efficacy (r = 0.40, p < 0.0001). After adjusting for confounders, child STOFHLA was independently associated with child BMI Z-score (standardized B = −0.43, p < 0.0001). Overall adjusted r-squared for the regression model was 38%. Child STOFHLA contributed 13% to the overall model.

Conclusions

Child health literacy was negatively correlated with BMI Z-scores in overweight children, suggesting the need to consider health literacy in the intersection between self-efficacy and behavior change when planning interventions that aim to improve child BMI.     

The relationship between oral health and nutrition in older people

The oral health of older people is changing with reducing numbers of people relying on complete dentures for function, and retaining some natural teeth. Despite this there are substantial numbers of older people whose ability to chew foods is compromised by their oral health status, either because they have few or no natural teeth. This alteration results in individuals selecting a diet that they can chew in comfort. Such diets are low in fruits and vegetables intake with associated reduction in both non-starch polysaccharide and micronutrient intakes. There is also a trend for reduced dietary intake overall. Salivary flow and function may have an impact in relation to the ability to chew and swallow. Whilst there are few differences in salivary function in fit healthy unmedicated subjects, disease resulting in reduced salivary flow and particularly polypharmacy, with xerostomia as a side effect, are likely to have a role in older people. This paper explores the relationships between oral health status and food's choice and discusses the potential consequences for the individual of such dietary change.     

Cognitive impairment no dementia and associations with health literacy,self-management skills,and functional health status

ObjectivesTo determine the prevalence of cognitive impairment no dementia (CIND) among a diverse, community-based population, and establish associations between CIND and health literacy, chronic disease self-management and functional health status.Methods863 primary care adults without dementia aged 55–74. Adjusted logistic and linear regressions were used to assess associations between CIND (None, Mild, Moderate/Severe) and outcomes.Results36 % participants exhibited CIND. It was strongly associated with limited health literacy (Newest Vital Signs: Mild [OR 3.25; 95 % CI 1.93, 5.49], Moderate/Severe [OR 6.45; 95 % CI 3.16, 13.2]; Test of Functional Health Literacy in Adults: Mild [OR 3.46; 95 % CI 2.08, 5.75], Moderate/Severe [OR 8.82; 95 % CI 4.87, 16.0]; all p’s < 0.001) and poor chronic disease self-management (Mild [B = −11.2; 95 % CI −13.5, -8.90], Moderate/Severe CI [B = −21.0; 95 % CI −23.6, −18.4]; both p’s < 0.001). Associations between CIND and functional health status were non-significant.ConclusionsCIND was prevalent in this cohort, and strongly associated with requisite skills for managing everyday health needs.Practice ImplicationsAttention to subtle declines in chronic disease self-care may assist with CIND identification and care management within this population. When CIND is observed, clinicians should also expect and address difficulties with self-management.     

The psychometric testing of the functional,communicative, and critical health literacy tool

ObjectiveThe purpose of this study is to assess the validity and reliability of the English version of the FCCHL tool in urban and rural, socioeconomically vulnerable or unstable, chronic comorbid adults in the United States.MethodsA cross-sectional study measuring both validity and reliability.ResultsA total of 276 participants were recruited. Internal consistency was measured using Cronbach’s alpha of α = 0.87. External reliability was measured by test-retest methodology. Construct validity was measured using Confirmatory Factor Analysis that showed good fit. Criterion validity was measured by comparing the mean scores of the FCCHL tool sub-scales. Concurrent validity was measured by comparison of means of the FCCHL tool and education level compared to the NVS and s-TOFHLA.ConclusionThe results demonstrated that the FCCHL tools is measuring three different concepts. Overall, the FCCHL tool was seen to have good validity and reliability in the identified population.Practice ImplicationsThe FCCHL tool is a 14-item, self-report health literacy tool measuring more than functional health literacy. The tool can be used in practice to improve not only functional health literacy, but also communicative and critical which is highly applicable.     

Effect of cognitive dysfunction on the relationship between age and health literacy

Objective

Age is generally an inverse predictor of health literacy. However, the role of cognitive dysfunction among older adults in this relationship is not understood.

Methods

We conducted a cross-sectional survey of 446 adult patients in a large urban academic level one trauma center, assessing health literacy and cognitive dysfunction.

Results

Removing older patients (60 years of age and older) who screened positive for cognitive dysfunction attenuated the relationship between age and health literacy (r = −0.16, p = 0.001 vs. r = −0.35, p < 0.0001). Older patients screening positive for cognitive dysfunction had significantly lower health literacy than older patients screening negative and patients less than 60 years; health literacy scores did not generally differ significantly between the latter groups.

Conclusion

Much of the relationship between age and health literacy was driven by cognitive dysfunction among a subset of older adults.

Practice implications

Our findings suggest that older patients with cognitive dysfunction have the greatest need for health literacy interventions.     

Association between health literacy and child and adolescent obesity

Objective

We tested the association between child and parental health literacy (HL) and odds of child and adolescent obesity.

Methods

We conducted an anonymous cross-sectional survey of a convenience sample of English-speaking child-parent dyads. Newest Vital Sign (NVS) measured HL. We used multivariable logistic regression to test adjusted association between child and parental NVS and obesity. Analyses were stratified for school-aged children (aged 7–11) vs. adolescents (aged 12–19).

Results

We surveyed 239 child-parent dyads. Median child age was 11 [inter-quartile range 9–13]; 123 (51%) were male; 84% Medicaid recipients; 27% obese. For children, the odds of obesity [adjusted odds ratio (95% confidence interval)] decreased with higher parent NVS [0.75 (0.56,1.00)] and increased with parent obesity [2.53 (1.08,5.94)]. For adolescents, odds of obesity were higher for adolescents with the lowest category of NVS [5.00 (1.26, 19.8)] and older parental age [1.07 (1.01,1.14)] and lower for Medicaid recipients [0.21 (0.06,0.78)] and higher parental education [0.38 (0.22,0.63)].

Conclusion

Obesity in school-aged children is associated with parental factors (obesity, parental HL); obesity in adolescents is strongly associated with the adolescent's HL.

Practice implications

Strategies to prevent and treat obesity should consider limited HL of parents for child obesity and of adolescents for adolescent obesity.     

Time to sign: The relationship between health literacy and signature time

Objective

To evaluate the relationship between amount of time taken to sign one's name and health literacy.

Methods

A prospective, one time assessment was conducted on a convenience sample of 98 patients recruited in an inner-city outpatient internal medicine clinic. The amount of time required to sign (i.e. initiation to completion of writing) was measured by stopwatch. Health literacy was measured with the REALM.

Results

The sample averaged 54.1 (SD 16.2) years of age. Twenty-seven percent had less than high school education and 33% had a terminal general equivalency diploma or high school degree. The time required to sign ranged from 0.91 to 21.3 s. Sixty-two percent of the sample had health literacy challenges. Signature time was longest for those with inadequate health literacy (mean 10.0 s), compared with marginal (7.3 s) and adequate (4.7 s, p ≤ 0.001). Signature time remained significant in a logistic regression model after controlling for education and age (AOR = 0.785, CI = 0.661–0.932).

Conclusion

Individuals with signatures completed in six seconds or less were highly likely to display adequate health literacy.

Practice implications

Signature time may offer a practical and quick approach to health literacy screening in the health care setting.     

Beyond reading alone: The relationship between aural literacy and asthma management

Objectives

To examine the relationship between literacy and asthma management with a focus on the oral exchange.

Methods

Study participants, all of whom reported asthma, were drawn from the New England Family Study (NEFS), an examination of links between education and health. NEFS data included reading, oral (speaking), and aural (listening) literacy measures. An additional survey was conducted with this group of study participants related to asthma issues, particularly asthma management. Data analysis focused on bivariate and multivariable logistic regression.

Results

In bivariate logistic regression models exploring aural literacy, there was a statistically significant association between those participants with lower aural literacy skills and less successful asthma management (OR: 4.37, 95%CI: 1.11, 17.32). In multivariable logistic regression analyses, controlling for gender, income, and race in separate models (one-at-a-time), there remained a statistically significant association between those participants with lower aural literacy skills and less successful asthma management.

Conclusion

Lower aural literacy skills seem to complicate asthma management capabilities.

Practice implications

Greater attention to the oral exchange, in particular the listening skills highlighted by aural literacy, as well as other related literacy skills may help us develop strategies for clear communication related to asthma management.     

A mismatch between population health literacy and the complexity of health information: an observational study

Background

Low health literacy is associated with poorer health and higher mortality. Complex health materials are a barrier to health.

Aim

To assess the literacy and numeracy skills required to understand and use commonly used English health information materials, and to describe population skills in relation to these.

Design and setting

An English observational study comparing health materials with national working-age population skills.

Method

Health materials were sampled using a health literacy framework. Competency thresholds to understand and use the materials were identified. The proportion of the population above and below these thresholds, and the sociodemographic variables associated with a greater risk of being below the thresholds, were described.

Results

Sixty-four health materials were sampled. Two competency thresholds were identified: text (literacy) only, and text + numeracy; 2515/5795 participants (43%) were below the text-only threshold, while 2905/4767 (61%) were below the text + numeracy threshold. Univariable analyses of social determinants of health showed that those groups more at risk of socioeconomic deprivation had higher odds of being below the health literacy competency threshold than those at lower risk of deprivation. Multivariable analysis resulted in some variables becoming non-significant or reduced in effect.

Conclusion

Levels of low health literacy mirror those found in other industrialised countries, with a mismatch between the complexity of health materials and the skills of the English adult working-age population. Those most in need of health information have the least access to it. Efficacious strategies are building population skills, improving health professionals’ communication, and improving written health information.     

The menopause and oral health

Objectives

To review the literature about oral symptoms and signs at the menopause with an emphasis on hormone replacement therapy (HRT). To give practical guidelines for women and their physicians in menopause-related oral health problems.

Methods

The PubMed and Cochrane databases was searched until mid January 2009 with key words such as “menopause”, “menopausal complaints”, “postmenopausal complaints” and “oral diseases”, “oral discomfort”, “dental health”, “dental diseases”, “saliva”, “burning mouth syndrome”, “dry mouth”, “xerostomia”. Because of a scarcity of controlled studies no systematic review could be conducted.

Results

Oral discomfort is found in many menopausal women in addition to more general climacteric complaints. The principal peri- and postmenopausal symptoms are dry mouth and burning mouth (glossodynia) which, in turn, may increase the occurrence of oral mucosal and dental diseases, such as candidiasis. The mechanisms of hormone-related oral symptoms and signs are not known although oestrogen receptors, for example, have been detected in the oral mucosa and salivary glands. In principle, the histology of oral and vaginal mucosa is very similar and thus their symptoms might share a common cause. Yet, hormone replacement therapy use does not necessarily prevent or help women with oral symptoms.

Conclusion

Properly controlled long-term randomized studies are needed to assess the effect of HRT on oral discomfort. Future gene profiling could identify women who may or may not benefit from HRT with regard to oral symptoms.     

The relationship between health literacy and knowledge improvement after a multimedia type 2 diabetes education program

Objective

Multimedia diabetes education programs (MDEP) have the potential to improve communication and education of those with low health literacy. We examined the effect of a MDEP targeted to patients with low literacy on knowledge and assessed the association between literacy and knowledge improvement.

Methods

We showed the MDEP to 190 patients recruited from clinics at a federally qualified health center and an academic health center. We measured diabetes knowledge before and after viewing the MDEP.

Results

Seventy-nine percent of patients had adequate literacy, 13% marginal, and 8% inadequate literacy. Patients across all literacy levels had significant increases in knowledge scores after viewing the MDEP (p-value < 0.001). Patients with inadequate literacy learned significantly less after the MDEP (adjusted beta-coefficient = −2.3, SE = 0.70) compared to those with adequate literacy.

Conclusions

A MDEP designed for those with low literacy significantly increased diabetes knowledge across literacy levels. However, the MDEP did not overcome the learning gap between patients with low and high literacy.

Practice implications

A literacy appropriate MDEP may be an effective way to teach patients about diabetes. Combining the MDEP with other education methods may improve comprehension and learning among those with low literacy. Research is needed to identify which characteristics of low-literate patients influence the ability to learn health information. Identifying these factors and incorporating solutions into a diabetes education intervention may help bridge the learning gap related to literacy status.     

Understanding the impact of family caregiver cancer literacy on patient health outcomes

OBJECTIVE: Family caregivers play a significant role in the diagnosis, treatment, and recovery of individuals with cancer. This position paper reviews and links the research on family caregiving and health information with the importance of cancer literacy. METHOD: Review of literature obtained through searching in Academic Search Premier, EBSCO, Communication and Mass Media Complete, PsychArticles, PsycInfo, and Health Source: Nursing/Academic Edition library databases. RESULTS: Family members are important sources of health information, informal caregivers who learn and enact medical procedures, and influential aspects of patients' healthcare and treatment decision-making, but are not seriously considered by healthcare practitioners or researchers in terms of assessing and improving health literacy. Further, very few studies have directly examined or acknowledged the potential importance of family caregiver health literacy. CONCLUSION: The extent to which family caregivers can comprehend the health information they receive along with the patient is crucial for the patient to achieve the most successful health outcome. PRACTICE IMPLICATIONS: To acknowledge the impact that family caregiver health literacy could have on patient health outcomes, targeted practical recommendations for understanding family caregiver health literacy in the cancer context are proposed: (1) family member health literacy should be assessed; (2) close relational partners should be trained as peer health educators; (3) written cancer information should be provided directly to family caregivers; (4) health interactions between family caregivers and patients should be improved; (5) theoretical perspectives into the understanding of family caregiver health literacy should be integrated into practice; and (6) patient and family caregiver health literacy should be improved.     

Analysis of the relationship among health awareness and health literacy,patient satisfaction levels with primary care in patients admitting to primary care health centers

Objective

The aim of the study was to examine the relationships between health literacy, primary care satisfaction levels and health awareness of the patients who were admitted to primary care centers (Family Health Centers).

The relationship between health literacy and perceived shared decision making in patients with breast cancer

Objectives

We explored the relationship between patient-perceived shared decision making (SDM) and three domains of health literacy (HL) in patients with breast cancer.

Functional health literacy mediates the relationship between socio-economic status,perceptions and lifestyle behaviors related to cancer risk in an Australian population

Objective

To determine if functional health literacy (FHL) mediates the relationship between socio-economic status, and perception of the risk of lifestyle behaviors for cancer.

Methods

Cross-sectional, random population survey, 2824 people aged ≥15 years, September–October 2008, included newest vital sign measure of FHL.

Results

Less than adequate FHL occurred in 45.1%. People who perceived behavioral factors (smoking, diet, obesity, alcohol, physical activity) to be not important, or did not know if they were important cancer risks, were more likely to have inadequate FHL. In a logistic regression model adjusted for age, gender, education, income, occupation, country of birth and area of residence, inadequate FHL was associated with 2–3 (OR = 1.9; 95% CI: 1.2–3.0) and 4 or more self-reported lifestyle risk factors (OR = 2.8; 95% CI: 1.6–5.0). In a structural equation model of the relationship of socio-economic status, perceptions of risk and behaviors there was significant mediation effect of FHL on the path from SES to health perceptions, estimated 29.4% of the total effect.

Conclusion

A specific focus on the literacy demands made on individuals from health promotion and materials with a view to improving health communication is indicated.

Practice implications

Health literacy is important for health promotion.     

Information seeking behavior and perceived health literacy of family caregivers of persons living with a chronic condition. The case of spinal cord injury in Switzerland

ObjectiveTo examine the information seeking behavior and health literacy of caregivers of individuals living with spinal cord injury in Switzerland and their impact on the caregiving experience.MethodsNationwide survey of family caregivers of people with spinal cord injury (N = 717). Caregivers aged 18+ who assisted with activities of daily living were included. Self-reported information seeking behavior, including topics, preferred sources, and health literacy were assessed and analyzed.ResultsHealth professionals were the most trusted source of information. Among information-seekers, higher health literacy levels were shown to be associated with lower subjective caregiver burden and, in turn, with higher caregivers’ satisfaction with own health.ConclusionCaregivers use information on different topics and coming from different sources. In order for information to improve the caregiving experience, however, caregivers need health literacy skills to make sense of it.Practice implicationsBuilding health literacy is a promising approach to support caregivers in their activities, reduce their subjective burden, and even to improve their health. Interventions should consider involving health professionals, as the most trusted source of information, and address both health-related and more practical issues.     

eHealth literacy: extending the digital divide to the realm of health information

Background

eHealth literacy is defined as the ability of people to use emerging information and communications technologies to improve or enable health and health care.

Objective

The goal of this study was to explore whether literacy disparities are diminished or enhanced in the search for health information on the Internet. The study focused on (1) traditional digital divide variables, such as sociodemographic characteristics, digital access, and digital literacy, (2) information search processes, and (3) the outcomes of Internet use for health information purposes.

Methods

We used a countrywide representative random-digital-dial telephone household survey of the Israeli adult population (18 years and older, N = 4286). We measured eHealth literacy; Internet access; digital literacy; sociodemographic factors; perceived health; presence of chronic diseases; as well as health information sources, content, search strategies, and evaluation criteria used by consumers.

Results

Respondents who were highly eHealth literate tended to be younger and more educated than their less eHealth-literate counterparts. They were also more active consumers of all types of information on the Internet, used more search strategies, and scrutinized information more carefully than did the less eHealth-literate respondents. Finally, respondents who were highly eHealth literate gained more positive outcomes from the information search in terms of cognitive, instrumental (self-management of health care needs, health behaviors, and better use of health insurance), and interpersonal (interacting with their physician) gains.

Conclusions

The present study documented differences between respondents high and low in eHealth literacy in terms of background attributes, information consumption, and outcomes of the information search. The association of eHealth literacy with background attributes indicates that the Internet reinforces existing social differences. The more comprehensive and sophisticated use of the Internet and the subsequent increased gains among the high eHealth literate create new inequalities in the domain of digital health information. There is a need to educate at-risk and needy groups (eg, chronically ill) and to design technology in a mode befitting more consumers.     

Collective caregivers: A novel examination of health literacy management approaches

ObjectiveHealth literacy and communication skills are necessary for family caregivers who often work in pairs, known as collective caregiving. Health literacy management is a relational process where communication between caregivers can be a barrier or pathway to improving or co-creating health literacy. The purpose of this study was to examine how collective caregivers manage health literacy.MethodsSemi-structured interviews were conducted separately for 42 caregiving pairs (n = 84). The interview guide was developed using a cancer caregiver health literacy framework. Caregiving pairs were placed into one of three collective caregiving communication patterns (absolute concordant, semi-concordant, absolute discordant). Interviews were audio-recorded, transcribed, and a thematic analysis was performed by independent coders.ResultsThe analysis revealed three different health literacy management approaches: a defined approach where caregiver roles were clearly designated (absolute concordant pairs); a contrasting approach where one caregiver was the health literacy expert (semi-concordant pairs); an independent approach characterized by individual information seeking, processing, and patient/provider engagement (absolute discordant pairs).ConclusionsHealth literacy support should address aspects of the family system such as caregiver-caregiver communication which influence variance in health literacy management.Practice implicationsOur study can inform provider communication and healthcare interventions aimed at supporting health literacy for caregivers.
