Lower health literacy predicts smoking relapse among racially/ethnically diverse smokers with low socioeconomic status

Digital Communication Inequalities Among U.S. Adults Reporting Current Cigarette Use

INTRODUCTION

To reduce tobacco-related health problems, it is critical to reach people who smoke with smoking cessation information and treatment. However, digital communication inequalities may limit access to online information sources.

METHODS

Digital device ownership, high-speed internet access, and online health information-seeking were examined among adults reporting current smoking in the Health Information National Trends Survey (n=847). Data were collected in 2019 and 2020 and analyzed in 2022. Multivariable logistic regression models examined associations between demographics, digital technology access, and online health information-seeking.

RESULTS

Only 47.6% (95% CI 39.0%, 56.3%) of adults aged 65+, 54.2% of Black/African American adults (95% CI 37.8%, 69.8%), and 59.6% with high school or less education (95% CI 51.5%, 67.1%) reported high-speed internet access (vs. 74.0% overall, 95% CI 68.9%, 78.6%). Inequalities in device ownership, high-speed internet access, and online health information-seeking were found by education and income. Adults with high school or less education (vs. college or more) had 78% lower odds of digital device ownership (aOR 0.22, 95% CI 0.08, 0.59) and 75% lower odds of high-speed internet access (aOR 0.25, 95% CI 0.09, 0.71). High-speed internet access (vs. no digital device or high-speed internet) was associated with 4.9 times greater odds of online health information-seeking (95% CI 1.81, 13.4).

CONCLUSIONS

Digital communication inequalities among adults who smoke exist. Understanding digital technology access among lower income populations could inform the development and delivery of interventions and health communication strategies to improve health outcomes among this population.

The association between health literacy and e-cigarette use: evidence from Zhejiang, China

Objectives

The worldwide popularity of electronic cigarettes (ECIG) is becoming a public health concern. Compared to conventional cigarettes (CIG), the harm caused by ECIG is more insidious. Studies have shown that lower health literacy (HL) is associated with CIG use; however, the relationship between HL and ECIG use remains controversial. Because ECIG emerged more recently than CIG, there are fewer relevant studies, and the sample populations and evaluation methods of HL in existing studies differ. This study conducted a large-sample survey to examine the relationship between HL and ECIG use.

Methods

As part of the 2022 China Health Literacy Survey, a total of 60,998 valid questionnaires were collected from September to November in 2022 using a stratified multistage probability proportional to the population size sampling frame. Chi-square tests and multinomial logistic regression was used to analyze the relationship between HL and ECIG use. Some demographic variables were included as covariates in the analysis.

Results

The study showed that the average HL score and the HL level of Zhejiang residents in 2022 were 42.8 and 30.8%, respectively. The prevalence of CIG and ECIG was 19.7 and 1.0%, respectively; 19% of participants exclusively used CIG, while only 0.3% of participants used ECIG exclusively; dual users accounted for 0.6%. After adjusting for covariates, adequate HL was associated with lower odds of ECIG-exclusive use (odds ratio [OR] = 0.452, p < 0.001), CIG-exclusive use (OR = 0.833, p < 0.001), and dual use (OR = 0.632, p < 0.001). Young age, male sex, unmarried status, high-income status, and absence of chronic disease were also associated with ECIG use.

Conclusion

HL was a protective factor against both patterns of ECIG use, especially ECIG-exclusive use. Health policymakers and public health practitioners should consider HL as a potential measure for ECIG control.

The influence of health literacy and knowledge about smoking hazards on the intention to quit smoking and its intensity: an empirical study based on the data of China's health literacy investigation

OBJECTIVE

This study explored the relationship between smokers' health literacy, knowledge of smoking hazards, and their intention to quit.

METHODS

Based on data from the 2019 Health Literacy and Tobacco Use Surveillance among residents of a city in Zhejiang Province, 1120 male smokers were screened. Differential tests were used to analyze whether smokers with varying levels of health literacy and knowledge about smoking hazards differed in their intention to quit smoking and the intensity of their intention. A multi-factor logistic regression model was constructed to explore the extent of these differences.

RESULTS

Only 24.8% of smokers had higher health literacy. Among smokers, those with an intention to quit had a higher health literacy level compared to those without such intention (32.7% vs. 17.0%, p < 0.001). Health literacy levels did not differ significantly between groups with different intensity of intention to quit (34.2% vs. 31.9% vs. 30.1%, p = 0.435). About 48.7% of the smokers a higher level of knowledge about smoking hazards. It was more prevalent in the intent to quit group compared to the no intent to quit group (54.0% vs. 43.4%, p < 0.001), and the low intent to quit group had lower knowledge compared to the moderate and high intent to quit groups (49.1% vs. 56.6% vs. 63.4%, p = 0.011). After adjusting for other influences, smokers with lower health literacy were less likely to have intention to quit (OR = 0.659, p = 0.016). And the association between knowledge about smoking hazards and whether smokers have the intention to quit is no longer significant, but it significantly affects the intensity of the intention to quit among smokers who already have the intention (OR = 0.623, p = 0.005).

CONCLUSION

General health literacy may play a role in facilitating smokers' progression from the stage of no intent to quit to one of intent to quit, but a more specific understanding of the harms of smoking may be needed to increase the strength of intent to quit.

Association of health literacy with smoking behavior among Chinese men

Health literacy may constitute a modifiable determinant of smoking behavior and intention to quit. Little is known about the extent to which health literacy affects smoking or quitting smoking. We assessed the nationally representative cross-sectional datasets from the China Health Literacy Surveillance (CHLS) initiated in 2018. Using polytomous logistic regression models, the study investigated the association of health literacy with smoking behavior and the intention to quit smoking among men aged 15-69 in China. After confounding factors were controlled, compared with having below basic health literacy, having adequate health literacy appeared to be an independent protective factor from current smoking [current smoking vs never smoking: adjusted odds ratio [OR], 0.88; 95% confidence interval (CI), 0.81-0.96; p = 0.003; current smoking vs former smoking: adjusted OR, 0.77; 95% CI, 0.64-0.92; p = 0.003], while having intermediate health literacy was associated with current smoking vs never smoking (adjusted OR, 1.09; 95% CI, 1.02-1.17; p = 0.011) or former smoking vs never smoking (adjusted OR, 1.22; 95% CI, 1.06-1.40; p = 0.005). And having adequate health literacy was associated with intending to quit among current smokers (adjusted OR, 1.25; 95% CI, 1.10-1.42; p < 0.001). Findings provide evidence that health literacy may serve as a critical and independent protective factor for reducing poor smoking behavior or enhancing cessation intention among men. Efforts should focus on developing and evaluating intervention to control tobacco use among men with low health literacy level.

A Call to Action on Assessing and Mitigating Bias in Artificial Intelligence Applications for Mental Health

Advances in computer science and data-analytic methods are driving a new era in mental health research and application. Artificial intelligence (AI) technologies hold the potential to enhance the assessment, diagnosis, and treatment of people experiencing mental health problems and to increase the reach and impact of mental health care. However, AI applications will not mitigate mental health disparities if they are built from historical data that reflect underlying social biases and inequities. AI models biased against sensitive classes could reinforce and even perpetuate existing inequities if these models create legacies that differentially impact who is diagnosed and treated, and how effectively. The current article reviews the health-equity implications of applying AI to mental health problems, outlines state-of-the-art methods for assessing and mitigating algorithmic bias, and presents a call to action to guide the development of fair-aware AI in psychological science.

Using the Unified Theory of Acceptance and Use of Technology (UTAUT) and e-health literacy(e-HL) to investigate the tobacco control intentions and behaviors of non-smoking college students in China: a cross-sectional investigation

BACKGROUND

Non-smoking college students are starting to smoke in increasing numbers, which shows that their tobacco control situation seems not optimistic. The UTAUT and e-HL are commonly used models and theories to predict health behaviors, while there are few studies on tobacco control. This paper aims to study the influencing factors of tobacco control intention and behavior of non-smoking college students in China by combining the UTAUT and e-HL.

METHODS

Based on the stratified sampling method, 625 college students from 12 universities were selected. Data were collected using a self-made questionnaire designed based on the UTAUT and e-health literacy scales. Data were analyzed by SPSS 22 and AMOS 26, including descriptive statistics, one-way variance analysis and structural equation model analysis.

RESULTS

The results of one-way variance analysis showed that there were significant differences in the score of non-smoking college students' tobacco control intention or behavior by hometowns, monthly living expenses, and parents' smoking history. Performance expectancy, effort expectancy, social influence had direct positive effects on behavioral intention. Facilitating condition, behavioral intention had direct positive impacts on use behavior and e-HL had an indirect positive impact on use behavior.

CONCLUSIONS

The combination of the UTAUT and e-HL can be used as an appropriate framework to predict the influencing factors of non-smoking college students' intention and behavior of tobacco control. Improving performance expectancy, effort expectancy, and e-HL among non-smoking college students, creating positive social environments, and providing facilitating condition are key aspects of increasing their tobacco control intention and behavior. It is also beneficial to promote the implementation of smoke-free campus and smoke-free family projects.

Proposed Questions to Assess the Extent of Knowledge in Understanding the Radiology Report Language

Radiotherapy and diagnostic imaging play a significant role in medical care. The amount of patient participation and communication can be increased by helping patients understand radiology reports. There is insufficient information on how to measure a patient's knowledge of a written radiology report. The goal of this study is to design a tool that will measure patient literacy of radiology reports. A radiological literacy tool was created and evaluated as part of the project. There were two groups of patients: control and intervention. A sample radiological report was provided to each group for reading. After reading the report, the groups were quizzed to see how well they understood the report. The participants answered the questions and the correlation between the understanding of the radiology report and the radiology report literacy questions was calculated. The correlations between radiology report literacy questions and radiology report understanding for the intervention and control groups were 0.522, p < 0.001, and 0.536, p < 0.001, respectively. Our radiology literacy tool demonstrated a good ability to measure the awareness of radiology report understanding (area under the receiver operator curve in control group (95% CI: 0.77 (0.71-0.81)) and intervention group (95% CI: 0.79 (0.74-0.84))). We successfully designed a tool that can measure the radiology literacy of patients. This tool is one of the first to measure the level of patient knowledge in the field of radiology understanding.

Tobacco-related health inequalities among Black Americans: A narrative review of structural and historical influences

We conducted a narrative literature review to examine contributing factors of disparities in tobacco usage and outcomes affecting Black Americans. We propose potential solutions that can be used to effectively address these disparities. We identified historical factors; socioeconomic factors; targeted marketing/advertising; the influence of racism/discrimination; neighborhood socioeconomic disadvantage; and mass incarceration. We call for more thorough examinations of these factors as a key element of tobacco-focused research and interventions to eliminate the disproportionate burdens faced by Black Americans. We advocate for greater emphases on the impacts of personal and structural racism on tobacco usage and outcomes affecting Black Americans.

Mapping the evidence on identity processes and identity-related interventions in the smoking and physical activity domains: a scoping review protocol

INTRODUCTION

Smoking and insufficient physical activity (PA), independently but especially in conjunction, often lead to disease and (premature) death. For this reason, there is need for effective smoking cessation and PA-increasing interventions. Identity-related interventions which aim to influence how people view themselves offer promising prospects, but an overview of the existing evidence is needed first. This is the protocol for a scoping review aiming to aggregate the evidence on identity processes and identity-related interventions in the smoking and physical activity domains.

METHODS

The scoping review will be guided by an adaption by Levac et al of the 2005 Arksey and O'Malley methodological framework, the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses: Extension for Scoping Review (PRISMA-ScR) and the 2017 Joanna Briggs Institute guidelines. It will include scientific publications discussing identity (processes) and/or identity-related interventions in the context of smoking (cessation) and/or physical (in)activity, in individuals aged 12 and over. A systematic search will be carried out in multiple databases (eg, PubMed, Web of Science). Records will be independently screened against prepiloted inclusion/exclusion criteria by two reviewers, using the Active Learning for Systematic Reviews machine learning artificial intelligence and Rayyan QCRI, a screening assistant. A prepiloted charting table will be used to extract data from included full-text articles. Findings will be reported according to the PRISMA-ScR guidelines and include study quality assessment.

ETHICS AND DISSEMINATION

Ethical approval is not required for scoping reviews. Findings will aid the development of future identity-related interventions targeting smoking and physical inactivity.

The Influence of Alcohol Consumption on Tobacco Use among Urban Older Adults: Evidence from Western China in 2017

Background: Tobacco use is a global public health concern due to its association with a myriad of health hazards and costs. Previous studies have found that the disinhibiting influence of alcohol consumption may lead to an increase in tobacco use. In this study, we investigated why alcohol consumption is associated with tobacco use among older adults in Western China, and we attempted to explain the mechanisms that underlie the link between alcohol consumption and tobacco use. Methods: In this cross-sectional study, we employed a representative sample of 812 urban individuals aged 60 and older in 2017 in Western China. Results: We found that alcohol consumption (OR = 2.816, 95%CI: 1.770–4.479) was positively associated with tobacco use. Additionally, other factors, including gender (OR = 0.023, 95%CI: 0.009–0.060), age (OR = 0.758, 95%CI: 0.634–0.906), health literacy (OR = 0.977, 95%CI: 0.959–0.995) and functional impairment (OR = 0.871, 95%CI: 0.767–0.988) were also strongly related to tobacco use. Conclusions: Consistent with the results of existing studies, our findings demonstrated the disinhibiting influence of alcohol consumption on tobacco use, which confirmed the theoretical mechanisms that underlie the alcohol–tobacco link and implied the co-occurrence and co-use of alcohol and tobacco, which are used as “social lubricants” in the Chinese context. The importance of other factors related to tobacco use were also discussed. As the tobacco epidemic is combatted, joint interventions tailored to concurrent control over alcohol and tobacco need to be performed, and corresponding male-specific and age-specific health education and the reinforcement of health literacy must be considered as important priorities.

Measuring the Structures of the Health Belief Model Integrated with Health Literacy in Predicting University Students' Adoption of Smoking Preventive Behaviors

Objectives

One of the priorities of public health in reducing smoking is to prevent young people from becoming smokers. Health literacy (HL), smoking, and preventive behaviors are related. Moreover, HL has a potential impact on strengthening the Health Belief Model (HBM). Considering the high prevalence of smoking among university students, the current study was conducted to measure the structures of the HBM integrated with HL in predicting university students' adoption of smoking preventive behaviors.

Methods

This was a cross-sectional descriptive study. Three hundred and forty dormitory students of Shahid Beheshti University of Medical Sciences (Teheran, Iran) in 2016, were selected through single-stage cluster sampling for the study. The data gathering tool was a researcher-made questionnaire based on the HBM and the HL inventory for adults (HELIA). The data were analyzed using the SPSS software version.16.

Results

The multiple regression analysis showed that the application of health information from five dimensions of HL, perceived susceptibility, self-efficacy, and decision-making dimensions were the predictors of smoking prevention. Also, the structures of this integrated model were able to anticipate 36.5% of the behavioral changes.

Conclusion

The HBM integrated with HL can be used as an appropriate framework for designing educational programs to encourage university students to adopt smoking preventive behaviors.

Current state of unhealthy living characteristics in Black/African American and Latino populations: Tobacco use

Over the past six decades, the United States has significantly improved tobacco-related health outcomes through mass efforts in policies, research, and behavioral and clinical interventions. Disparities persist, however, among communities of color who continue to suffer disproportionate rates of cardiovascular disease and other tobacco-related morbidity and mortality. In this review, we synthesize and discuss the tobacco use lifecycle across the lifespan, with special attention paid to socioecological determinants of tobacco-use behavior among Blacks and Latinos. This review summarizes the permeability of tobacco use and tobacco-related determinants across multiple levels of influence, from the individual to the societal, and highlights gaps in the tobacco control and prevention landscape. Given its continued evolution and impact on socially disadvantaged communities, we conclude with recommendations for improving current tobacco research and treatment and prevention efforts.

Interventions for Adherence Improvement in the Primary Prevention of Cardiovascular Diseases: Expert Consensus Statement

Over the last 2 decades, the management of chronic disease in Korea has been improved, but it has gradually stagnated. In order to improve care and reduce cardiovascular morbidity and mortality, it is crucial to improve primary prevention of cardiovascular diseases. In recent international guidelines for hypertension, diabetes, hyperlipidemia, obesity, and other conditions, adherence issues have become more frequently addressed. However, in terms of implementation in practice, separate approaches by dozens of related academic specialties need to be integrated into a systematic approach including clinician’s perspectives such as the science behind adherence, clinical skills, and interaction within team approach.

In primary prevention for cardiovascular diseases, there are significant barriers to adherence including freedom from symptoms, long latency for therapeutic benefits, life-long duration of treatment, and need for combined lifestyle changes. However, to implement more systematic approaches, the focus on adherence improvement needs to be shifted away from patient factors to the effects of the treatment team and healthcare system. In addition to conventional educational approaches, more patient-oriented approaches such as patient-centered clinical communication skills, counseling using motivational strategies, decision-making by patient empowerment, and a multi-disciplinary team approach should be developed and implemented. Patients should be involved in a program of self-monitoring, self-management, and active counseling. Because most effective interventions on adherence improvement demand greater resources, the health care system and educational or training system of physicians and healthcare staff need to be supported for systematic improvement.

The Relationship between Different Levels of Health Literacy and Smoking Prevention Among Medical Sciences Student

Background

Higher rates of Smoking among university students have been reported in various studies. On the other hand, health literacy (HL) can improve health behaviors. In fact, identifying factors affecting the adoption of smoking preventive behaviors such as HL can help prevent and reduce the prevalence of smoking among people. The aim of this study was to identify the relationship between different levels of HL and adoption of smoking preventive behaviors among university student in 2016.

Methods

This was a cross-sectional descriptive study. Three hundred and forty-seven dormitory students of Shahid Beheshti University of Medical Sciences in Iran were selected through single-stage cluster sampling for the study. Data were collected using a measure of HL (the HL inventory for adults-HELIA) and a designed questionnaire to assess the adoption of smoking preventive behaviors. The data were analyzed using SPSS software version. 16 and descriptive statistical and Logistic regression test.

Results

The mean (SD) of the score for adoption of smoking preventive behaviors and HL were 45.91 (12.99) and 70.52 (14.12) out of 100, respectively. The results showed that the adoption of smoking preventive behaviors had significant relationship with variables such as HL, gender, father's education and not smoking (P < 0.05).

Conclusions

Less adoption of smoking preventive behaviors was seen in students with lower levels of HL, female students, students with illiterate fathers and smokers. Therefore, it seems essential to take these factors into consideration in designing preventive programs for smoking in target groups.

The Effect of Health Literacy Levels on Successful of Smoking Cessation Therapy: A Survey Study

Aim: In this study, it was aimed to evaluate the effect of the health literacy levels of patients given smoking cessation treatment on the success of smoking cessation treatment. Methods: In this study, 152 participants between the ages of 18-70 applied to a tertiary hospital smoking cessation outpatient clinic. The Fagerström Test for Nicotine Dependence was used to determine the level of cigarette addiction of the participants, and the European Health Literacy Scale was used to evaluate the levels of health literacy. Results: When the health literacy levels of the participants with cigarette addiction were evaluated, 38 (25%) were inadequate, 64 (42.1%) were problematic. When the participants' smoking cessation status and general health literacy levels were compared, it was found to be statistically significant. It was determined that as the health literacy level increased, the success rates of individuals increased in smoking cessation therapy. Conclusions: We have shown that increasing the level of health literacy is effective in increasing the success of smoking cessation treatment. Increasing health literacy should be part of the fight against smoking. This effect should be demonstrated by future studies on large populations. Keywords: smoking cessation, health literacy, addiction

A Pilot Study of Nicotine Replacement Therapy Sampling and Selection to Increase Medication Adherence in Low-Income Smokers

INTRODUCTION

Adherence to smoking cessation medications remains suboptimal, particularly among low-income smokers. Guided, experiential sampling of nicotine replacement therapies (NRTs) may increase NRT adherence and smoking cessation over gold standard counseling plus NRT. The present pilot study aimed to examine feasibility, acceptability, and preliminary efficacy of a novel experiential intervention.

AIMS AND METHODS

This pilot randomized controlled trial (N = 83) compared gold standard smoking cessation treatment (four weekly sessions of behavioral counseling followed by self-selected combination NRT in week 5) to a novel experiential approach (ie, In Vivo; four weekly sessions of sampling each short form of NRT-gum, lozenge, inhaler, nasal spray-in-session while wearing the nicotine patch followed by NRT selection in week 5). Both groups received 8 weeks of nicotine patch plus their selected additional short form NRT for smoking cessation followed by a 1-month assessment.

RESULTS

Screening and enrollment rates supported feasibility. In Vivo was comparable in acceptability with the gold standard of care intervention; however, there was greater attrition in the In Vivo group compared with the gold standard of care group. Results suggested higher medication adherence and improvements in smoking behavior in the In Vivo intervention; with generally small-to-medium effect sizes.

CONCLUSIONS

This experiential approach to sampling NRT is feasible and acceptable to low-income people who smoke. This intervention may increase adherence and reduce harmful smoking behavior but needs to be tested on a larger scale.

IMPLICATIONS

Medication adherence remains a significant impediment to the successful smoking cessation. The results of this study suggest that guided sampling of NRT products improves adherence among low-income smokers. Additionally, this approach yielded greater improvements in smoking behavior compared with gold standard smoking cessation treatment. This intervention shows promise as a feasible smoking cessation treatment for low-income smokers.

The Association Between Health Literacy and Tobacco Use: Results from a Nationally Representative Survey

Dual use of conventional cigarettes and electronic cigarettes presents an emerging public health issue. Previous research has demonstrated a negative relationship between health literacy and conventional cigarette (CIG) use. However, the relationship between health literacy and e-cigarette (ECIG) use remains unclear. This studies examines the possible association of health literacy and CIG, ECIG, or dual use. A multinomial regression was used to model the association between health literacy and current CIG use, current ECIG use, or dual tobacco use status using state-optional data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS; N = 40,404). One-third of the sample (N = 13,478; 33.3%) had initiated tobacco use. Approximately 36.6% of participants exclusively used cigarettes. A smaller proportion of participants were dual users of ECIG and CIGs (7.0%) and e-cigarette exclusive users (4.5%). After adjusting for covariates, higher levels of oral health literacy was associated with lower odds of current dual use. However, there was no significant association between written HL and either conventional cigarette use or electronic cigarette use or after adjusting for covariates. Oral messaging around the dangers of CIG use may be effective at lowering odds of CIG or dual use, especially for those with higher levels of HL. Further research is needed to examine how to best disseminate information regarding the health risks of ECIGs.

Health Literacy Within a Diverse Community-Based Cohort: The Multi-Ethnic Study of Atherosclerosis

BACKGROUND

Health literacy has yet to be described in a non-clinical, racially diverse, community-based cohort.

METHODS

Four questions assessing health literacy were asked during annual phone encounters with Multi-Ethnic Study of Atherosclerosis (MESA) participants between 2016 and 2018 (n = 3629). We used prevalence ratios (PRs) with 95% confidence intervals (CIs) to characterize how demographic and acculturation factors related to limited health literacy. Models adjusted for age, sex, and race/ethnicity, and race/ethnicity-stratified models were also examined.

RESULTS

Limited health literacy was prevalent in 15.4% of the sample. Participants who were older, female, lower-income, or less acculturated were at greater risk for having limited health literacy. Chinese, Hispanic, and Black participants were more likely than White participants to have limited health literacy. Patterns were similar when stratified by race/ethnicity.

DISCUSSION

Within MESA limited health literacy was common, particularly among Chinese and Hispanic participants, with some of the variance explained by differences in acculturation.

Health Literacy Mediates the Association Between Socioeconomic Status and Productive Aging Among Elderly Chinese Adults in a Newly Urbanized Community

Productive aging, or older adults engaging in paid or unpaid activities that produce socially valued goods or services, has been suggested to have the beneficial impact on older adults' health and well-being. We performed a cross-sectional study to examine the influence of health literacy on the relationship between socioeconomic status (SES) and productive aging among older Chinese adults in a newly urbanized community. Data was collected from 995 older adults from a newly urbanized community between June and August 2013 in Chengdu, China. We used structural equation modeling (SEM) to test the hypothesized relationship among SES, health literacy and productive aging. Results showed that education attainment and income had a direct positive effect on health literacy (β = 0.47and β = 0.15, respectively). Education had a partial indirect effect on productive aging through health literacy (β = 0.27). And health literacy was an important factor in improving the productive aging of the elderly. Interventions targeting health education and health promotion should be taken to improve health literacy of older adults under the background of urbanization, especially for those with lower SES.

Health Knowledge about Smoking, Role of Doctors, and Self-Perceived Health: A Cross-Sectional Study on Smokers' Intentions to Quit

Limited empirical work has been done to compare the effects that health knowledge and advice from doctors have on smokers’ intentions to quit. This paper examines the association of smokers’ intentions to quit with health knowledge, advice from doctors, and self-perceived health. A sample of 2509 smokers aged 15–69 years old in Ningbo was used from China’s National Health Literacy Surveillance survey, conducted in 2018 and 2019. Respondents were asked whether they agree smoking causes stroke, heart attack, lung cancer; and heart diseases in adults, lung illnesses in children, and lung cancer in adults, by secondhand smoke, respectively. Using the logistic model, we found that knowing that smoking causes stroke and lung cancer more than doubles the odds of one’s intention to quit (OR = 2.705, p < 0.01), the effect of which is much greater than knowing that smoking causes lung cancer only (OR = 1.795, p < 0.01). Doctors’ advice to quit is more important than health knowledge, in terms of predicting smokers’ past cessation behaviours. In addition, smokers’ self-perceived health is negatively associated with their decisions to quit. This paper highlights that more resources should be directed towards training health care providers to advise smokers to quit, which might be more effective than health education alone.

Health-Promoting Behaviors, Health Literacy, and Levels of Knowledge about Smoking-Related Diseases among Smokers and Non-smokers: A Cross-Sectional Study

Background

For generations, cigarette smoking has presented an important public health concern. This study aimed to compare the health-promoting behavior, exercise capacity, physical activity level, health literacy, and knowledge level of smoking-related diseases between smokers and non-smokers.

Methods

The study included 71 smokers (mean age, 32.69±8.55 years) and 72 non-smokers (mean age, 31.88±9.94 years) between the ages of 20 and 60 years. Assessments included a 6-minute walking test (6MWT), Godin Leisure-Time Physical Activity Questionnaire, Health-Promoting Lifestyle Profile II (HPLP-II), Cardiovascular Risk Factors Knowledge Level Scale (CARRF-KL), Asthma/COPD Awareness Questionnaire, the World Health Organization Quality of Life-Bref questionnaire (WHOQoL-Bref [TR]), and Health Literacy Questionnaire (HLQ).

Results

The results from the study show that the number of coronary artery disease risk factors measured significantly higher among the smoker group members when compared to that of the non-smoker group members (p=0.001). Smokers had significantly lower %6MWT distance than non-smokers (84.83±4.72 and 93.45±7.16, respectively; p<0.05). However, there were no significant differences between the smokers and non-smokers in terms of physical activity, CARRF-KL, HLQ, WHOQoL-Bref, and HPLP-II subscales or total scores (p>0.05). Additionally, while only forty-one smokers (57.7%) were active, 48 of the non-smoker group was active (66.7%).

Conclusion

Smokers suffer greater negative effects to their exercise capacity in comparison to non-smokers. Although smokers and non-smokers have similar levels of health literacy and similar levels of knowledge about cardiovascular disease risk factors and obstructive lung diseases, health professionals could continue to further increase individuals’ awareness of smoking-related risk factors and continue to emphasize the importance of physical activity and exercise for protecting cardiopulmonary health.

'The newest vital sign among pregnant women attending women wellness and research Centre in Qatar: a cross-sectional study'

Background

Health literacy is a vital strategy to consider when designing health-promoting programs, and health literacy is a priority in Qatar’s national health agenda. In the context of pregnancy, inadequate health literacy has been linked to several adverse outcomes among pregnant women such as unplanned conception, smoking, and lack of multi-vitamin intake. Given the paucity of data, this study aimed to assess the level of health literacy and its determinants among pregnant women in the State of Qatar.

Methods

An analytical cross-sectional design was utilized. First, we piloted the measurement tools on 10% of the calculated sample size. Accordingly, the items of the measurement tools were revised. Next, we utilized a structured questionnaire to interview the participants about their socio-demographic characteristics, pregnancy-related factors, and the Newest Vital Sign Tool. A chi-square test was employed to investigate the association level among variables, with significance set to P < 0.05. A logistic regression model was used to identify the factors associated with a low literacy level.

Results

We found that almost four in 10 pregnant women (n = 138,45.4%) had inadequate health literacy. Furthermore, the insufficient level of health literacy was significantly associated with low educational background, decreased household income, and primigravida. However, uncontrolled glycaemia was the only significant predictor of inadequate health literacy through logistic regression. The scale was found to be reliable, with a calculated Cronbach’s alpha of 0.8.

Conclusions

Low health literacy is common among pregnant women in the State of Qatar. Thus, public health officials should focus on delivering tailored health literacy interventions to pregnant women in the country.

Framing pregnancy-related smoking cessation messages for women of reproductive age

INTRODUCTION

Communicating harms of smoking and benefits of quitting to tobacco users to motivate cessation is critical to reduce the burden of tobacco-related disease. Most messaging strategies focus on health risks of smoking using loss-framing; yet, gain-framed messages to increase confidence in quitting have shown promise for smokers with lower self-efficacy. This study examined the impact of message framing on perceived effectiveness of targeted, pregnancy-related smoking cessation messages among pregnant and not-pregnant smoking women of reproductive age.

METHODS

An obstetrics-gynecological clinic-based sample of female, current smokers of reproductive age (18-44 years old) was recruited during January to May 2019 (n = 135). Participants self-reported ratings for 10 pregnancy-related cessation messages (half gain-framed) on a validated perceived effectiveness scale. Multivariable regression analyses were conducted using generalized estimating equations to account for clustering by message themes.

RESULTS

Gain-framed messages were rated significantly higher (0.20; p < 0.01) compared to loss-framed messages for perceived effectiveness, after accounting for quit intentions, self-efficacy to quit, health literacy, cessation risk perceptions, nicotine dependence, and pregnancy status.

CONCLUSIONS

Gain-framed health messages about cessation were deemed to be more effective than loss-framed messages among adult female smokers. Targeted, positively framed messages to highlight the benefits of quitting to women of reproductive age show promise as a strategy to promote smoking cessation.

Health status of female Moldovan migrants to Italy by health literacy level and age group: a descriptive study

BACKGROUND

Migration flows from Eastern Europe to Italy have been large and continue to grow. The purpose of this study was to examine the health status of a population of Moldovan migrant women, and their access to health care services in northern Italy, by age group and health literacy level.

METHODS

We administered an ad-hoc questionnaire to adult Moldovan women. A bivariate analysis was conducted to test the association between health literacy and age groups with other variables (lifestyles, symptoms and diseases, access to health services). A stepwise logistic regression analysis was run to test the association between access to primary care and health literacy. Moreover, the study compare Moldovan women data with a sample of Italian women of the same age range living in North-Eastern region.

RESULTS

Our sample included 170 Moldovan women (aged 46.5 ± 12.3) in five occupational categories: home care workers (28.2%); cleaners (27.1%); health care workers (5.9%); other occupations (28.8%); and unemployed (10%). Active smokers were twice as prevalent among the women with a low health literacy. Health literacy level also determined access to primary healthcare services. For all age groups, the Moldovan sample reported a higher prevalence of allergies, lumbar disorders and depression than the Italian controls.

CONCLUSIONS

The reported prevalence of some diseases was higher among Moldovan migrant women than among Italian resident women. Health literacy was associated with the migrant women's lifestyle and the use of primary health care services, as previously seen for the autochthonous population.

Investigating the Smoking Cessation Informational Needs of Cancer Patients and Informal Caregivers

Continued smoking at the time of a cancer diagnosis can severely impact the efficacy of cancer patient treatment and survival. The time of diagnosis can serve as a "teachable moment" for smoking cessation education, since patients may be receptive to discussions about quitting. Caregivers may have a pivotal role in supporting patients with their cessation efforts. The purpose of this study was to identify the smoking cessation informational needs of cancer patients and their caregivers. A needs assessment survey was administered to both patients and caregivers that assessed information needs across five domains: (1) General Information and Support; (2) Smoking, Health and Disease; (3) Relationships; (4) Testimonials; (5) Interventions. Mean importance scores were determined based on the proportion of respondents who ranked how important individual items were within the broader domains. Forty patients and twenty-two caregivers completed the survey. Among patients, the mean age was 61 years, with 35% diagnosed with a head and neck malignancy and 62% reporting as current smokers. Among caregivers, the mean age was 58 years, with 81% reporting to be the patient's immediate family member and 50% as current smokers. The General Information and Support domain was rated as the most important domain for both cancer patients and caregivers. The top preferred modality for receiving smoking cessation education across all domains was pamphlets for both groups. This study identifies the key informational elements that should be considered in the development of smoking cessation resources to meet the informational needs of cancer patients and caregivers.

Responses to Graphic Warning Labels among Low-income Smokers

Objective: Graphic warning labels (GWLs) are effective in communicating tobacco-related harms. Methods: In this mixed-methods study, we used purposive sampling to recruit 100 low-income smokers in the San Francisco Bay Area between October 2017 and February 2018 to participate in an intervention promoting smoke-free homes. We presented the 2009 Food and Drug Administration-proposed GWLs and explored perceptions of affect, efficacy, and appeal using questionnaires at baseline, 3- and 6-months follow-up. Because of participants' interest in this topic, we subsequently conducted a qualitative sub-study among 20 participants exploring perceived efficacy of GWLs on smoking cessation. Results: In all, 87.3% and 59.2% agreed that GWLs were useful and would motivate cessation behaviors, respectively, at baseline. We found that the most common responses were shock (61.8%) and disgust (55.3%), whereas anger (29.0%) and annoyance (19.7%) were less common. Participants also reported that GWLs unequivocally illustrating smoking's harmful effects were more appealing than non-specific images, as were images that depicted positive cessation-related effects. Conclusions: GWLs appear to be an important health communication among low-income smokers. Future studies on GWLs should examine the association of negative affect and cessation among this population.

The impact of lifestyle behaviours, physical activity and smoking on morbidity and mortality in patients with rheumatoid arthritis

Rheumatoid arthritis (RA) is associated with pain, disability and increased risk of developing comorbidities and premature mortality. While these poor outcomes have improved in line with advances in the treatment of RA, they still persist to some degree today. Physical activity and smoking are two areas of patients' lives where changes may have a substantial impact on the poor outcomes associated with RA. Physical activity in RA has been well studied, with many randomised trials indicating the benefits of physical activity on pain and disability. A number of observational studies have assessed the impact of smoking on RA, also indicating the benefits of quitting smoking on RA-related outcomes, but with less consistent findings, potentially due to epidemiological challenges (e.g. collider bias, recall bias). There are also a number of barriers preventing patients making these positive lifestyle changes, such as lack of time and motivation, lack of knowledge and advice, as well as disease-specific barriers, such as pain and fatigue.

Influence of Puerperal Health Literacy on Tobacco Use during Pregnancy among Spanish Women: A Transversal Study

Background: Despite the fact that tobacco use during pregnancy produces adverse perinatal effects, some women continue to smoke. Health literacy (HL) is essential for health outcomes in adults. However, little is known about HL in pregnant women or postpartum women. The study aimed to analyse the relationship between the degree of HL of women during the early puerperium and tobacco use during pregnancy. Methods: A multicentre, descriptive, cross-sectional study was carried out with women in the early puerperium in a region of eastern Spain, between November 2017 and May 2018. Their HL level was obtained using the Newest Vital Sign (NVS) tool. Multivariate logistic models were adjusted to estimate the magnitude of association with tobacco use in pregnancy. Odds ratios (OR) were estimated with a 95% confidence interval. Results: 193 were included in the total. 29.5% (57) of pregnant women smoked tobacco during pregnancy, with a smoking cessation rate of 70.1% (40) while pregnant. 42.0% (81) of pregnant women had inadequate or limited HL. A low level of HL was strongly associated with tobacco use, adjusted by catchment area and age of first pregnancy (LRT p < 0.001; ROC curve = 0.71, 95% CI: 0.64–0.79). Conclusion: A low HL is associated with tobacco consumption during pregnancy. Whether low HL reflects the wide constellation of already-known socioeconomic, political and commercial determinants of tobacco use, or whether incorporating HL support interventions strengthens tobacco cessation activities in pregnancy, warrants further research. Still, it should be considered as essential to understanding the health disparities related to its consumption.

Follow-Up Adherence Is Associated with Outcomes After Endoscopic Sinus Surgery

BACKGROUND

Clinical follow-up after endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) allows for assessment of the sinonasal cavity, debridement, and tailoring of medical therapies. Frequency and timing of postoperative clinical visits is debated, but the impact of adherence on disease-specific outcomes is not well understood. In this longitudinal study, we assessed the association between follow-up adherence and quality of life (QOL) outcomes in the 12 months after ESS.

METHODS

A retrospective review of patients undergoing ambulatory ESS for CRS between 11/2016 and 1/2018 was performed. We assessed sociodemographic characteristics, radiographic severity, and QOL utilizing the 22-item sinonasal outcome test (SNOT-22). Patients were categorized as "non-adherent," "moderately-adherent," and "fully-adherent" to a 1-, 3- and 5-week postoperative visit schedule.

RESULTS

A total of 166 patients met the inclusion criteria. Of these, 55 (33.1%) were fully-adherent, 105 (63.2%) were moderately-adherent, and 6 (3.6%) were non-adherent within the 6 weeks following ESS. In the immediate postoperative period, fully-adherent patients demonstrated worse QOL (SNOT-22: 31.2 ± 23.1 vs 27.5 ± 17.6, P = .047). This cohort also had greater psychological dysfunction at baseline and 12-months (P < .05) after ESS. Extra-nasal symptom scores increased at a lower rate in the fully-adherent cohort (0.12 vs 1.29 points per 6 months, P = .038), as did ear/facial symptoms (1.17 vs 3.05 points per 6 months, P = .044).

CONCLUSION

Despite worse symptom severity in the immediate postoperative period, patients who are more adherent to the follow-up schedule demonstrated slower return of symptoms in the extra-rhinological and ear-facial domains. These findings suggest that clinical adherence and management may impact the long-term evolution of ESS outcomes.

Exposure to second-hand smoking as a predictor of fetal loss: Egypt Demographic and Health Survey 2014

BACKGROUND

Exposure to tobacco smoking during pregnancy has been shown to be associated with elevated risk of adverse pregnancy outcomes such as miscarriage and stillbirth. However, little is known regarding the association between passive smoking and birth outcomes. This study aims to measure the prevalence of passive smoking and assess its relationship with adverse birth outcomes.

METHODS

Self-reported birth outcomes (stillbirth/miscarriage/abortion) was the dependent variable that was regressed against self-reported exposure to household smoking along with various individual and community-level factors. We used propensity score matching to identify the sample and used regression analysis to quantify the association between passive smoking and birth outcomes. Sensitivity analysis was conducted to check for the robustness of the associations.

RESULTS

Of the 5540 women studied, about half (50.3%, 95% CI=49.3-51.3) reported being exposed to smoking by household members. The prevalence of stillbirth was 14.6% (95% CI=13.9-15.3). In the logistic regression analysis, the confounder-adjusted OR of stillbirth in relation to exposure to smoking was 1.321 (95% CI=1.150-1.517). In the subgroup analysis, we found that the association was significant among certain age groups only.

CONCLUSION

The findings of the present study imply a mildly positive association between the occurrence of stillbirth and exposure to smoking in the household.

Characteristics of us adults attempting tobacco use cessation using e-cigarettes

BACKGROUND

Use of e-cigarettes for tobacco cessation efforts is a growing trend in the United States. However, little is known about the factors that determine the use of e-cigarettes for this specific purpose.

METHODS

This study examined current and former cigarette smokers that reported ever using e-cigarettes. Data were obtained from a 2018 Texas population health assessment survey (n = 569) and weighted to be representative to Texas. A multivariable logistic regression was used to assess the socio-demographic and behavioral correlates of using e-cigarettes for tobacco cessation.

RESULTS

Overall, 41.3% of e-cigarette users reported using them for tobacco cessation. Among ever e-cigarette users, Non-Hispanic blacks (aOR: 0.21; 95% CI, 0.07-0.64), males (aOR: 0.40; 95% CI, 0.20-0.80), and individuals not confident in obtaining health information (aOR: 0.38; 95% CI, 0.15-0.96) were less likely to use e-cigarettes for tobacco use cessation. Conversely, among ever e-cigarette users, odds of using e-cigarettes for tobacco cessation were higher among those who were 35-44 years old (aOR: 3.68, 95% CI: 1.26-10.71), those who received advice to quit smoking from a healthcare professional (aOR: 2.77, 95% CI, 1.36-5.64), and those with more than 5 years since their last routine checkup (aOR: 3.91; 95% CI, 1.23-12.45).

CONCLUSION

Findings from this study suggest that both health behaviors and sociodemographic factors predict use of e-cigarettes for the purpose of tobacco cessation. Furthermore, the relationship between use of e-cigarettes as a cessation device and being advised to quit tobacco use by a healthcare professional calls for additional investigation.

Enhancing Smoking Risk Communications: The Influence of Health Literacy and Message Content

Background

Efforts are needed to ensure that smokers with lower health literacy are provided with understandable and impactful information about the health consequences of smoking and benefits of quitting.

Purpose

To test the influence of health literacy on smokers' responses to health risk messages manipulated on framing (gain vs. loss) and emotionality (factual vs. emotional).

Methods

Participants (N = 402) were randomized to evaluate one of four sets of smoking risk messages (factual gain-framed, factual loss-framed, emotional gain-framed, or emotional loss-framed). Multiple linear regressions examined main effects of health literacy, message emotionality, and message framing on: (a) risk perceptions, (b) behavioral expectations (i.e. cut down, limit, quit), and (c) risk knowledge. Two-way interactions of health literacy with emotionality and framing were examined for these outcomes. Analyses were based on theory-driven, a priori hypotheses.

Results

As hypothesized, main effects emerged such that smokers with higher health literacy reported stronger risk perceptions and knowledge retention regardless of message type. Additionally, emotional (vs. factual) and gain- (vs. loss-) framed messages were associated with certain lower risk perceptions regardless of health literacy level. Consistent with hypotheses, two-way crossover interactions emerged between health literacy and emotionality. Among smokers with higher health literacy, factual messages produced higher perceived risk and stronger expectations for quitting. Among smokers with lower health literacy, emotional messages produced higher perceived risk and stronger expectations for quitting.

Conclusions

Health literacy plays an important role in influencing how smokers respond to different risk messages. One's health literacy should be considered when determining whether risk communications emphasize factual or emotional content.

Impact of adding and removing warning label messages from cigarette packages on adult smokers' awareness about the health harms of smoking: findings from the ITC Canada Survey

INTRODUCTION

Adding messages to cigarette health warning labels (HWLs) about the harms of smoking increases awareness of these health facts, but little is known about the impact of removing messages. This is the first study to directly investigate the impact of adding and removing messages from cigarette HWLs on smokers' awareness of harms.

METHODS

Data were drawn from nine waves of the International Tobacco Control (ITC) Canada Survey, a national representative cohort of adult smokers (n=5863) conducted nearly annually between 2002 and 2013-2014. Two analytical approaches were conducted: generalised estimating equation (GEE) regression models estimated adjusted percentages of correct smoking-related health statements at each wave and segmented regression analyses modelled temporal trends in awareness before and after the revisions by measuring the difference in slopes.

RESULTS

Adding messages to HWLs significantly increased awareness that smoking causes blindness (OR=3.36 (95% CI 2.71 to 4.18); p<0.001; estimated increase of 1.01 million smokers in Canada) and bladder cancer (OR=2.14 (95% CI 1.71 to 2.66), p<0.001; estimated increase of 1.09 million smokers). Adding the warning that nicotine causes addiction did not significantly impact smokers' awareness. Removing messages was shown to decrease awareness that cigarette smoke contains carbon monoxide (OR=0.53 (95% CI 0.41 to 0.70), p<0.001; estimated decrease of 342 000 smokers) and smoking causes impotence (p=0.007 for the difference in slopes; estimated decrease of 354 000 smokers).

CONCLUSIONS

Adding messages to HWLs increases smokers' awareness of health facts, but removing messages decreases awareness. These findings demonstrate the importance of carefully considering the implications of adding and especially removing messages from HWLs and the importance of regularly revising warnings.

Differential associations of health literacy with Austrian adolescents' tobacco and alcohol use

OBJECTIVES

Tobacco use and alcohol use have their origin in adolescence, and risky use of these substances is amongst the leading preventable causes of morbidity and mortality. Health literacy (HL) encompasses the skills that are decisive to make appropriate health decisions in this context. Given the paucity of evidence on the link between HL and adolescents' health behaviors, the present study examined overall HL and different components of HL and their associations with smoking and alcohol use among 13 to 17-year-old Austrian students.

STUDY DESIGN

Data were obtained from a national survey carried out in Austria (N = 4219; 56% females) as part of the Health Behaviour in School-aged Children: World Health Organization (WHO) collaborative cross-national study.

METHODS

We tested two structural equation models, one including the overall HL scale as the predictor and one with the three subscales of HL 'finding,' 'understanding and appraising,' and 'applying' health-related information as predictors of smoking and alcohol use.

RESULTS

Although overall HL was related to all indicators of adolescents' smoking and drinking, the three HL components had differential effects on these behaviors. The easier it was for the participants to 'understand and appraise' and 'apply' health-related information, the less frequently they had smoked and drunk alcohol and the less was the amount of alcohol they had consumed. Contrarily, the easier it was for the participants to 'find' information, the more they had smoked and drunk alcohol.

CONCLUSIONS

Our results indicate that availability of health-related information may be insufficient on its own to prevent or reduce risky substance use. This is of particular importance for the development and improvement of primary prevention programs targeting adolescent populations.

The social patterning of electronic nicotine delivery system use among US adults

There is little research examining the social patterning of electronic nicotine delivery system (ENDS) use. This study investigated the association between socioeconomic status (SES) (education, income, and employment status) and current and former ENDS use. Data were collected from 2561 participants from the American Heart Association Tobacco Regulatory and Addiction Center (A-TRAC) online survey. Participants were 18-64 years old and reported demographic, SES, and ENDS use. Poisson regression was used to estimate prevalence ratios (PR 95% confidence interval-CI) of participants' current and former (vs. never) ENDS use. Models were adjusted for age, sex, sexual orientation, race/ethnicity, marital status, and reasons for ENDS use. In the unadjusted analysis, ENDS use was primarily patterned by education and employment status. College educated persons (vs. those with less than a high school diploma) had a 37% greater prevalence of current ENDS use (PR 1.37, 95% CI 1.20-1.55), and a 16% greater prevalence of former ENDS use (PR 1.16, 95% CI 1.06-1.28) in the fully-adjusted model. Persons with household incomes above $90 K (vs. less than $20,000) had a greater prevalence of current (PR 1.30, 95% CI 1.19-1.41) and former (PR 1.17, 95% CI 1.05-1.30) ENDS use. Those who were employed (vs. not employed) had a 13% greater prevalence of current ENDS use (PR 1.13, 95% CI 1.07-1.19) after full adjustment. Higher SES (vs. lower SES) persons were more likely to use ENDS.

Health Literacy and Attention to Cigarette Health Warning Labels among Rural Smokers

OBJECTIVES

We evaluated the association of health literacy and attention to the pictorial imagery of 9 health warning labels (HWLs) in a tobacco advertisement among rural US smokers. We hypothesized that lower health literacy would be associated with greater visual attention to pictorial portions of HWLs and evaluated the association between health literacy and recall of advertisement elements.

METHODS

Adult smokers from Appalachian Ohio (N = 180) viewed a pictorial HWL encompassing 20% or 33% of a cigarette advertisement while eye tracking software recorded eye movements toward the advertisement. Health literacy was measured with The Short Test of Functional Health Literacy in Adults.

RESULTS

Generalized linear regression revealed that every one-unit decrease in health literacy increased viewing time of the pictorial portion of the health warning label by 1.3 percentage points. Logistic regression revealed that the odds of recalling elements of the pictorial portion of the health warning label increased 20% for every one-unit increase in health literacy.

CONCLUSIONS

Rural smokers with lower health literacy view pictorial portions of health warning labels longer than those with greater health literacy supporting that health literacy is an important consideration in health communications, including future cigarette warning labels.

Health Literacy and Cardiovascular Disease: Fundamental Relevance to Primary and Secondary Prevention: A Scientific Statement From the American Heart Association

Health literacy is the degree to which individuals are able to access and process basic health information and services and thereby participate in health-related decisions. Limited health literacy is highly prevalent in the United States and is strongly associated with patient morbidity, mortality, healthcare use, and costs. The objectives of this American Heart Association scientific statement are (1) to summarize the relevance of health literacy to cardiovascular health; (2) to present the adverse associations of health literacy with cardiovascular risk factors, conditions, and treatments; (3) to suggest strategies that address barriers imposed by limited health literacy on the management and prevention of cardiovascular disease; (4) to demonstrate the contributions of health literacy to health disparities, given its association with social determinants of health; and (5) to propose future directions for how health literacy can be integrated into the American Heart Association's mandate to advance cardiovascular treatment and research, thereby improving patient care and public health. Inadequate health literacy is a barrier to the American Heart Association meeting its 2020 Impact Goals, and this statement articulates the rationale to anticipate and address the adverse cardiovascular effects associated with health literacy.

Simple screening tools to identify limited health literacy in a low-income patient population

Adults with limited health literacy have difficulty managing chronic conditions, higher hospitalization rates, and more healthcare expenditures. Simple screening tools have been developed, but limited work has evaluated instruments among low-income populations. This study assessed health literacy among primary care patients of a federally qualified health center, and compared a single screening question about perceived difficulty completing medical forms.A cross-sectional survey was administered to English-speaking patients ≥40 years. Both the Newest Vital Sign (NVS), a 6-item questionnaire, and a single-item screening question about perceived difficulty with completing medical forms, assessed health literacy. Logistic regression was used to identify predictors of inadequate health literacy and receiver operator curves compared the NVS and single-item question.Participants (n = 406) were, on average, aged 58.5 years (±11.3), 72.2% female, and identified as Hispanic/Latino (19.2%), non-Hispanic white (31.0%), non-Hispanic black (40.9%), or other (8.9%). Of the 406 participants, 335 (82.5%) completed the NVS. Patients who declined NVS were more likely to be older (P < .001) and male (P = .01). Only 13.7% had adequate health literacy. Older adults, Hispanic and non-Hispanic black patients, patients with missed office visits, and those reporting less confidence completing medical forms were significantly more likely to have inadequate health literacy. Perceived confidence completing medical forms demonstrated low sensitivity but high specificity at multiple thresholds.This is the first investigation to compare the NVS and confidence completing medical forms question. Many patients declined health literacy assessments, but health literacy screening may identify patients who need additional health education and resources.

The Methodological Quality and Effectiveness of Technology-Based Smoking Cessation Interventions for Disadvantaged Groups: A Systematic Review and Meta-analysis

Aims

To assess the methodological quality and effectiveness of technology-based smoking cessation interventions in disadvantaged groups.

Method

Four databases (EMBASE, Cochrane, Medline, and PsycInfo) were searched for studies conducted from 1980 to May 2016. Randomized controlled trials that compared a behavioral smoking cessation intervention delivered primarily through a technology-based platform (eg, mobile phone) with a no-intervention comparison group among disadvantaged smokers were included. Three reviewers assessed all relevant studies for inclusion, and one reviewer extracted study, participant and intervention-level data, with a subset crosschecked by a second reviewer.

Results

Thirteen studies targeting disadvantaged smokers (n =4820) were included. Only one study scored highly in terms of methodological rigor on EPOC criteria for judging risk of bias. Of the 13 studies using a technology-based platform, most utilized websites (n = 5) or computer programs (n = 5), and seven additionally offered nicotine replacement therapy. Technology-based interventions increased the odds of smoking cessation for disadvantaged groups at 1 month (odds ratio [OR] 1.70, 95% confidence interval [CI] 1.10, 2.63), 3 months (OR 1.30, 95% CI 1.07, 1.59), 6 months (OR 1.29, 95% CI 1.03, 1.62), and 18 months post-intervention (OR 1.83, 95% CI 1.11, 3.01).

Conclusion

Few methodologically rigorous studies were identified. Mobile phone text-messaging, computer- and website-delivered quit support showed promise at increasing quit rates among Indigenous, psychiatric and inpatient substance use disorder patients. Further research is needed to address the role technology-based interventions have on overcoming health inequalities to meet the needs of disadvantaged groups.

Implications

This review provides the first quantitative evidence of the effectiveness of a range of technology-based smoking cessation interventions among disadvantaged smokers, with separate estimates on the basis of intervention type, and cessation outcome measure. Providing cost-effective, easily accessible and real-time smoking cessation treatment is needed, and innovative technology-based platforms will help reach this endpoint. These interventions need to be tested in larger scale randomized controlled trial designs and target broader disadvantaged groups. Data collection beyond 6 months is also needed in order to establish the efficacy of these intervention approaches on long-term cessation rates among disadvantaged population groups.

Tobacco use and health insurance literacy among vulnerable populations: implications for health reform

BACKGROUND

Under the Affordable Care Act (ACA), millions of Americans have been enrolling in the health insurance marketplaces. Nearly 20% of them are tobacco users. As part of the ACA, tobacco users may face up to 50% higher premiums that are not eligible for tax credits. Tobacco users, along with the uninsured and racial/ethnic minorities targeted by ACA coverage expansions, are among those most likely to suffer from low health literacy - a key ingredient in the ability to understand, compare, choose, and use coverage, referred to as health insurance literacy. Whether tobacco users choose enough coverage in the marketplaces given their expected health care needs and are able to access health care services effectively is fundamentally related to understanding health insurance. However, no studies to date have examined this important relationship.

METHODS

Data were collected from 631 lower-income, minority, rural residents of Virginia. Health insurance literacy was assessed by asking four factual questions about the coverage options presented to them. Adjusted associations between tobacco use and health insurance literacy were tested using multivariate linear regression, controlling for numeracy, risk-taking, discount rates, health status, experiences with the health care system, and demographics.

RESULTS

Nearly one third (31%) of participants were current tobacco users, 80% were African American and 27% were uninsured. Average health insurance literacy across all participants was 2.0 (SD 1.1) out of a total possible score of 4. Current tobacco users had significantly lower HIL compared to non-users (-0.22, p < 0.05) after adjustment. Participants who were less educated, African American, and less numerate reported more difficulty understanding health insurance (p < 0.05 each.) CONCLUSIONS: Tobacco users face higher premiums for health coverage than non-users in the individual insurance marketplace. Our results suggest they may be less equipped to shop for plans that provide them with adequate out-of-pocket risk protection, thus placing greater financial burdens on them and potentially limiting access to tobacco cessation and treatment programs and other needed health services.

Measuring the health literacy of the Upper Midwest

Objectives

Health literacy—the ability to obtain, process, and understand basic health information—is a major determinant of an individual’s overall health and health care utilization. In this project, the authors examined predictors of health literacy levels, including numeracy and graphic literacy, among an adult population in the Upper Midwest.

Methods

The research was conducted at the Minnesota State Fair. Three previously validated scales were used to assess health literacy: Newest Vital Sign, the General Health Numeracy Test, and questions from Galesic and Garcia-Retamero’s Graph Literacy Scale. Demographic information—such as age, educational attainment, zip code, and other potential predictors and modifiers—was collected. Multivariate linear regression was conducted to examine the independent effects of educational attainment, race, ethnicity, gender, and rural or urban location on overall health literacy and scores on each of the individual instruments.

Results

A total of 353 Upper Midwest residents completed the survey, with the majority being white, college-educated, and from an urban area. Having a graduate or professional degree or being under the age of 21 were associated with increased health literacy scores, while having a high school diploma or some high school education, being Asian American, or being American Indian/Alaska Native were associated with lower health literacy scores.

Conclusion

Advanced health literacy skills, including the ability to calculate and compare information, were problematic even in well-educated populations. Understanding numerical and graphical information was found to be particularly difficult, and more research is needed to understand these deficits and how best to address them.

Social support mediates the association of health literacy and depression among racially/ethnically diverse smokers with low socioeconomic status

Nearly half of U.S. adults have health literacy (HL) difficulties, and lack the ability to effectively obtain, process, and understand health information. Poor HL is associated with depression, yet mechanisms of this relation are unclear. This study examined whether social support mediated the relation between HL and depressive symptoms in 200 low-socioeconomic status (SES), racially/ethnically diverse smokers enrolled in cessation treatment. Mediation analyses were conducted using bootstrapping and controlling for SES and nicotine dependence. In simple mediation models, social support [Interpersonal Support Evaluation List (ISEL) total, subscales (Appraisal, Belonging, Tangible)] mediated the effect of HL on depression, such that lower HL was associated with lower perceived support, which predicted higher depressive symptoms (ps < .05). A multiple mediation model, with ISEL subscales entered simultaneously as mediators, was significant (p < .05) but only the Belonging subscale demonstrating independent significance (p < .05). Thus, social support may be a critical factor underlying the HL-depression relationship in low-SES, racially/ethnically diverse smokers.
