Health literacy and the determinants of obesity: a population-based survey of sixth grade school children in Taiwan

Exploring Public Emotions on Obesity During the COVID-19 Pandemic Using Sentiment Analysis and Topic Modeling: Cross-Sectional Study

BACKGROUND

Obesity is a chronic, multifactorial, and relapsing disease, affecting people of all ages worldwide, and is directly related to multiple complications. Understanding public attitudes and perceptions toward obesity is essential for developing effective health policies, prevention strategies, and treatment approaches.

OBJECTIVE

This study investigated the sentiments of the general public, celebrities, and important organizations regarding obesity using social media data, specifically from Twitter (subsequently rebranded as X).

METHODS

The study analyzes a dataset of 53,414 tweets related to obesity posted on Twitter during the COVID-19 pandemic, from April 2019 to December 2022. Sentiment analysis was performed using the XLM-RoBERTa-base model, and topic modeling was conducted using the BERTopic library.

RESULTS

The analysis revealed that tweets regarding obesity were predominantly negative. Spikes in Twitter activity correlated with significant political events, such as the exchange of obesity-related comments between US politicians and criticism of the United Kingdom's obesity campaign. Topic modeling identified 243 clusters representing various obesity-related topics, such as childhood obesity; the US President's obesity struggle; COVID-19 vaccinations; the UK government's obesity campaign; body shaming; racism and high obesity rates among Black American people; smoking, substance abuse, and alcohol consumption among people with obesity; environmental risk factors; and surgical treatments.

CONCLUSIONS

Twitter serves as a valuable source for understanding obesity-related sentiments and attitudes among the public, celebrities, and influential organizations. Sentiments regarding obesity were predominantly negative. Negative portrayals of obesity by influential politicians and celebrities were shown to contribute to negative public sentiments, which can have adverse effects on public health. It is essential for public figures to be mindful of their impact on public opinion and the potential consequences of their statements.

Adolescents' health literacy is directly associated with their physical activity but indirectly with their body composition and cardiorespiratory fitness: mediation analysis of the Slovak HBSC study data

BACKGROUND

Health literacy is a core public health issue in relation to children and adolescents associated with multiple health behaviours and health outcomes. The aim of the study is to test the direct associations between health literacy, physical activity behaviour, health outcomes of body composition and cardiorespiratory fitness among Slovak adolescents and possible indirect effect of health literacy on health outcomes of body composition and cardiorespiratory fitness mediated by adolescents' physical activity behaviour.

METHODS

Data from the Slovak Health Behaviour in School-aged Children (HBSC) study conducted in 2022 were used. For the purposes of this study, a subsample of the adolescents (n = 508; mean age = 14.50; SD = 0.82; 54.3% boys) which provided HBSC questionnaire data on health literacy, moderate-to-vigorous physical activity and vigorous physical activity and participated in body composition (InBody 230) and cardiorespiratory fitness (20-m shuttle run test) measurements. Data were analysed using linear regression analysis.

RESULTS

The findings showed that higher health literacy of the adolescents was directly associated with higher frequency of physical activity represented by moderate-to-vigorous physical activity and vigorous physical activity and only with the visceral fat area in the crude model. Furthermore, there was an indirect effect of health literacy on cardiorespiratory fitness and most of the body composition variables (except the Body Mass Index) which was mediated by physical activity of the respondents.

CONCLUSIONS

Health literacy is indirectly associated to body composition and cardiorespiratory fitness through higher frequency of physical activity. It seems that health literacy as cognitive and social competencies need behavioural components to be involved in the proposed causal pathway between health literacy and health outcomes. Our findings may contribute to the process of creating a framework for future health literacy interventions in adolescents.

Relationships among Sleep Time, Physical Activity Time, Screen Time, and Nutrition Literacy of Adolescents: A Cross-Sectional Study in Chongqing, China

Background: Unhealthy lifestyles among adolescents are reaching alarming levels and have become a major public health problem. This study aimed to assess the relationship between sleep time, physical activity (PA) time, screen time (ST), and nutritional literacy (NL). Methods: This cross-sectional online study involving adolescents aged 10-18 years was conducted in September 2020 in 239 schools in Chongqing, China. NL was measured using the "Nutrition Literacy Scale for middle school students in Chongqing (CM-NLS)". According to the recommended by the Chinese dietary guidelines (2022), we divided the sleep time of junior high school students into <9 h and ≥9 h, high school students into <8 h and ≥8 h, divided the workdays into weekend PA time < 1 h and ≥1 h, and divided the workdays into weekend ST < 2 h and ≥2 h. The multinomial logistic regression model was used to examine the association. Results: A total of 18,660 adolescents (50.2% males) were included. The proportion of participants that were junior high school students and attended boarding schools was 57.2% and 65.3%, respectively. Compared with senior high school students, junior high school students had a higher level of NL. Whether on workdays or weekends, participants with sleep time ≥ 8/9 h, PA time ≥ 1 h, and ST < 2 h per day had higher levels of NL. On weekdays, participants who met the sleep time ≥ 8 h/9 h (OR = 1.48, 95% CI: 1.36, 1.62) and PA time ≥ 1 h (OR = 1.69, 95% CI: 1.59, 1.81) had higher reporting of NL levels. Conclusions: Sleep time, PA time, and ST were positively correlated with NL among adolescents, especially junior high school students.

Associations between GoSmart Channel, health literacy and health behaviours in adolescents: A population-based study

BACKGROUND

Health literacy is essential in the promotion of healthy lifestyle habits and chronic disease prevention.

OBJECTIVE

To assess the health literacy level among Hong Kong adolescents; to evaluate the association between access of an online health information platform (GoSmart Channel) and health literacy level; and to examine the association between health literacy level and various unhealthy behaviours.

DESIGN

This study recruited students from 10 local secondary schools in Hong Kong to assess the health literacy level among adolescents.

SETTINGS AND PARTICIPANTS

Participants were required to complete a self-administered questionnaire on health behaviours and health literacy using the Health Literacy Measure for Adolescents (HELMA). MAIN OUTCOME MEASURE: Data were analysed using descriptive statistics and multivariate regression modelling.

RESULTS

A total of 777 responses were collected. Overall, most (74.4%) of the adolescents in Hong Kong have limited health literacy (HELMA score <66). The majority (63.7%) of adolescents relied on their parents for health information, while 11.4% of the respondents sought information from the GoSmart Channel. The intervention of GoSmart Channel was significantly associated with better health literacy in almost all aspects among adolescents. Desired levels of health literacy were significantly associated with better perceived health (adjusted odds ratio: 2.04, p = .001) and negatively associated with a range of unhealthy and risky behaviours including unhealthy dietary habits, poor hygienic measures and physical inactivity.

DISCUSSION AND CONCLUSION

This study highlights the importance of improving health literacy among Hong Kong adolescents and the potential of technology-based interventions. The findings suggest the need for continued efforts to promote health literacy and healthy behaviours among adolescents, especially given the limited health literacy levels observed in the study.

PATIENT OR PUBLIC CONTRIBUTION

Members of the GoSmart.Net Built-on Project patient and public involvement and engagement group advised about survey development.

Topics Included in Health Literacy Studies in Asia: A Systematic Review

The study aimed to review general and specific health literacy studies in different countries in Asia to understand the progress of health literacy researches in the region. English-published studies with quantitative measurements of health literacy were collected through a systematic search in PubMed, Cochrane Library, Embase, and Web of Science, without publication dates limitation. A total of 156 articles on general health literacy, oral, mental, disease-specific health literacy, and eHealth literacy were collected. General health literacy was the most covered topic in 89 articles, followed by eHealth Literacy. Health literacy studies have been conducted in 16 countries and have been increasingly concerned in most of the countries in Asia. China had the largest number of articles, followed by Taiwan. Four studies had participants from more than one country. Education, age, health status, incomes, and living/residential area were significantly associated with health literacy levels in 156 studies, with the prevalence of 55.8%, 28.2%, 20.5%, 17.9%, and 10.9%, respectively. Lower health literacy was related to poorer health outcomes or lower quality of life in 71 studies.

Measuring adolescent health literacy in Taiwan: validation of the health literacy assessment scale for adolescents

BACKGROUND

This study aimed to validate the Chinese version of the Health Literacy Assessment Scale for Adolescents (HAS-A) and conduct a comparative analysis of adolescent health literacy between Taiwan and other countries.

METHODS

The Chinese version of the HAS-A was completed by 2,312 adolescents in the fifth and sixth grades of a primary school. Psychometric properties were examined using consistent internal reliability and confirmatory factor analysis. These assessments were compared with the results from different regions to explore health literacy inequality.

RESULTS

Construct validity was good, and internal consistency was acceptable. The scale, particularly regarding communication health literacy, was associated with parents' socioeconomic status, and family income had a more significant impact on children's health literacy than community income. Health literacy disparities appear in different countries, with Taiwan exhibiting the lowest level of communication health literacy.

CONCLUSION

The results indicate that the HAS-A is a valuable tool for assessing the health literacy of 10-11-year-old adolescents and can uncover health literacy inequality among different regions.

The development and cross-national validation of the short health literacy for school-aged children (HLSAC-5) instrument

Health literacy is an asset for and indicator of adolescents' health and wellbeing, and should therefore be monitored and addressed across countries. This study aimed to develop and validate a shorter version of the original 10-item health literacy for school-aged children instrument in a cross-national context, using data from the health behaviour in school-aged children 2017/18 survey. The data were obtained from 25 425 adolescents (aged 13 and 15 years) from seven European countries. Determination was made of the best item combination to form a shorter version of the health literacy instrument. Thereafter, the structural validity, reliability, measurement invariance, and criterion validity of the new 5-item instrument were examined. Confirmatory factor analysis showed a good model fit to the data across countries and in the total sample, confirming the structural validity (CFI = 0.995, TLI = 0.989, SRMR = 0.011, RMSEA = 0.031). The internal consistency of the instrument was at a good level across countries (α = 0.87-0.98), indicating that the instrument provided reliable scores. Configural and metric invariance was established across genders, ages, and countries. Scalar invariance was achieved for age and gender groups, but not between countries. This indicated that the factor structure of the scale was similar, but that there were differences between the countries in health literacy levels. Regarding criterion validity, structural equation modelling showed a positive association between health literacy and self-rated health in all the participating countries. The new instrument was found to be valid and reliable for the purposes of measuring health literacy among adolescents in a cross-national context.

The mortality risk in patients with early onset colorectal cancer: the role of comorbidities

The global incidence of early-onset colorectal cancer (EO-CRC) is increasing. Although the mortality rate is relatively stable, some comorbidities have been associated with a higher mortality rate. This study estimated the mortality risk in patients with EO-CRC with various comorbidities using real-world data to identify the high-risk group using Cox proportional regression for overall and cancer-specific mortality. The incidence rate of EO-CRC significantly increased from 6.04 per 100,000 population in 2007 to 12.97 per 100,000 population in 2017. The five-year overall mortality rate was 101.50 per 1000 person year and the cancer-specific mortality rate was 94.12 per 1000 person year. Patients with cerebrovascular disease (CVD) had a higher mortality risk (hazard ratio (HR): 1.68; 95% confidence interval (CI): 1.25-2.28; p=0.0007). After subgroup analyses based on age, sex, clinical stage, and treatment type, patients with CVD had a higher overall mortality risk compared to non-CVD patients, except for patients undergoing surgery and chemotherapy. Patients with chronic kidney disease had a higher mortality risk in the early clinical stages (HR: 2.31; 95% CI: 1.08-4.96; p=0.0138). Patients who underwent radiotherapy had a higher overall mortality risk (HR: 1.38; 95% CI: 1.04-1.85; p=0.0285) than those without liver disease. Identifying specific comorbidity mortality risks in patients with EO-CRC allows for risk stratification when screening target groups and may lower disease mortality.

A teacher professional development programme to enhance students’ critical health literacy through school-based health and physical education programmes

Health literacy is a critical asset for adolescents to develop given its positive impact on health outcomes. The few studies that have targeted teacher knowledge and attitudes show that teachers themselves find it difficult to: navigate the multi-modal nature of health information; critically evaluate the different modes and texts; and apply health-related information in a variety of contexts. This research study aimed to address this issue through developing and implementing a teacher professional development (PD) programme for three Australian secondary schools and nine Health and Physical Education (HPE) teachers to improve health literacy, particularly critical health literacy, content and pedagogies embedded in current HPE programmes. Fifteen HPE programmes were analysed using Nutbeam’s health literacy hierarchy and the Australian Curriculum: HPE outcomes and content, with this analysis informing a personalized PD programme. To evaluate how teachers experienced the personalized PD programme, interviews conducted at the completion of the PD programme were analysed using Braun and Clarke’s thematic approach. According to the teachers, the PD had improved their knowledge and understanding of the three levels of HL, including how to implement it into their practice. The personalized nature was a key strength of the PD programme as it allowed for changes to be made in a time-efficient manner, a known challenge for teachers. Teachers recommended the provision of additional resources that foster students’ critical health literacy levels and an additional session to ensure sustainable changes in planning and teaching practices.

Specificity of the Associations between Indices of Cardiovascular Health with Health Literacy and Physical Literacy; A Cross-Sectional Study in Older Adolescents

Background and Objectives: Cardiovascular health status (CVHS) is an important determinant of health, while it is theorized that health literacy (HL) and physical literacy (PL) could be directly related to CVHS. The aim of this study was to evaluate gender-specific associations between PL and HL and indices of CVHS in adolescence. Materials and Methods: The participants were 247 adolescents (177 females) from Split-Dalmatia county in Croatia who were tested on HL, PL, and CVHS (physical activity level (PAL) and lipid profile). The lipid profile included total cholesterol, triglycerides, high-density lipoproteins, non-high-density lipoprotein-cholesterol, and low-density lipoproteins. Gender-stratified multivariate cluster analysis (K-means clustering) was used to group participants into three homogenous groups on the basis of their HL and PL, while differences between clusters in CVHS were evidenced by analysis of the variance and consecutive post-hoc tests. Results: The lipid profile was better in girls with higher HL scores. Additionally, clusters consisting of participants with a better PL were characterized by higher PAL. We have found no evidence that HL is associated with PAL, while PL was not associated with the lipid profile. Conclusions: HL was specifically associated with direct indicators of health status (lipid profile) in girls, while PL was associated with PAL as a particular behavioral health indicator in both genders. The study highlights the necessity of including education of HL and PL in schools.

Health literacy as a key to improving weight status among Palestinian adolescents living in chronic conflict conditions: a cross-sectional study

OBJECTIVE

To examine the moderating role of health literacy in the association between direct exposure to violence and weight status among Palestinian adolescents.

DESIGN

A household cross-sectional study conducted in 2017.

SETTING

A Palestinian district of the West Bank.

PARTICIPANTS

Palestinian adolescents aged 11-16 years.

RESULTS

After excluding underweight adolescents from the 1200 who were initially recruited, the data of 1173 adolescents were analysed. A high proportion (62%) of adolescents were directly exposed to violence. The prevalence of obesity and overweight was 6.5% and 17.1%, respectively. The odds of obesity and overweight were 2.8 and 1.8 times higher among adolescents who were not exposed to domestic and school violence when they had low health literacy in the communication subscale. The odds of obesity were 62% and 57% lower among adolescents with high functional health literacy when exposed to domestic and school violence and to any form of violence, respectively. Among adolescents who were not exposed to any form of violence, those who had high health literacy in the communication subscale were 72% less likely to be obese compared with those who had low health literacy.

CONCLUSIONS

Health literacy moderated the association between direct exposure to violence and weight status. When health literacy levels were higher, lower obesity rates were observed among adolescents who were directly exposed to any form of violence or exposed either to political violence only or domestic and school violence only. The results warrant further investigation of the role of health literacy in adolescent health. It is recommended that policy-makers integrate the health literacy concept into both education and health systems.

Comparison of Health Literacy Assessment Tools among Beijing School-Aged Children

Health literacy is a broad and multidimensional construct, making its measurement and conclusions inconsistent. This study aims to compare the patterning of health literacy using different assessment tools and examine their impact on children's developmental outcomes. A cross-sectional study was conducted with 650 students in Years 7-9 from four secondary schools in Beijing. Health literacy was measured by the eight-item health literacy assessment tool (HLAT, score range 0-37), the six-item Newest Vital Sign (NVS, score range 0-6), and the 16-item Health Literacy Survey (HLS, score range 0-16). Based on Manganello's health literacy framework, information on upstream factors (e.g., gender, ethnicity, socioeconomic status) and developmental outcomes (e.g., health-promoting behaviours, health service use, global health status) was collected. Overall, the average scores for health literacy were 26.34 ± 5.89, 3.64 ± 1.64, and 13.72 ± 2.94, respectively, for HLAT, NVS, and HLS. The distribution of health literacy varied by socio-demographics and individual characteristics except for gender, no matter which health literacy assessment tool was used. The magnitude of associations between health literacy, its upstream factors and developmental outcomes was greater when using three-domain instruments (HLAT and HLS) than using single-domain instruments (NVS). The approach to health literacy measurement will influence the conclusion. Using multidimensional assessment tools may better capture a child's health literacy and contribute to the maximum efficiency and effectiveness of school-based health literacy interventions.

The role of health-based food choice motives in explaining the relationship between lower socioeconomic position and higher BMI in UK and US adults

Background/Objectives

Lower socioeconomic position (SEP) is associated with increased risk of higher BMI and developing obesity. No research to date has directly examined whether SEP differences in health-based food choice motives or executive function explain why lower SEP is associated with higher BMI.

Subjects/Methods

We analysed observational data from large samples of UK (N = 4130) and US (N = 1898) adults which included measures of SEP (education level, household income and subjective social status) and self-reported BMI. Participants also completed validated self-report measures on the extent to which their day-to-day food choices were motivated by health and weight control, as well as completing computerized tasks measuring inhibitory control (Stroop task) and working memory (Digit span task).

Results

Across both UK and US adults, the relationship between indicators of lower SEP and higher BMI were consistently explained by participants from lower SEP backgrounds reporting being less motivated by health when making food choices, which accounted for 18–28% of the association between lower SEP and higher BMI. There was no evidence that measures of executive function explained associations between SEP and BMI or moderated relations between food choice motives and higher BMI.

Conclusions

SEP differences in health-based food choice motives may play an important role in explaining why lower SEP is associated with an increased risk of higher BMI.

Children's Health Literacy in Relation to Their BMI z-Score, Food Intake, and Physical Activity: A Cross-Sectional Study among 8-11-Year-Old Children in The Netherlands

Overweight and obesity in children are an increasing public health problem. Health literacy (HL) is a determinant of obesity and body mass index (BMI) rates in adults, but few studies have addressed the impact of children’s own HL on their weight and lifestyle. In this study, we aim to assess the impact of Dutch children’s HL on (1) their BMI z-score, (2) dietary behaviour, and (3) the amount of physical activity (PA) they engage in. A sample of 139 children (age 8–11 years) filled out a digital questionnaire, including an HL measurement instrument and questions regarding their food intake and PA. Furthermore, the height and weight of the children were measured, and background information was collected using a parental questionnaire. Multiple regression revealed a significant positive relation between children’s HL and their PA. No significant association between children’s HL and their BMI z-score or dietary behaviour was found. HL of children in primary school thus has an impact on some aspects of children’s lifestyle, although more research in a larger, more diverse sample is needed to further investigate this.

Association Between Nutrition Literacy and Overweight/Obesity of Adolescents: A Cross–Sectional Study in Chongqing, China

Objective

The burden of overweight and obesity in adolescents is increasing rapidly. This study aimed to assess the association between nutrition literacy and overweight/obesity among adolescents in China.

Methods

This cross–sectional online study involving adolescents aged 10–18 years was conducted in September 2020 in 239 schools in Chongqing China. Overweight and obese adolescents were determined based on the International Obesity Task Force's recommended age–sex specific body mass index cutoff points. Nutrition literacy was measured using the “Nutrition literacy scale for middle school students in Chongqing (CM–NLS).” The CM–NLS included three subdomains (functional nutritional literacy, interactive nutrition literacy, and critical nutrition literacy). Multinomial logistic regression model was used to examine the association.

Results

A total of 18,176 adolescents (49.8% girls) were included. The prevalence of overweight and obesity was 9.6% and 17.0%, respectively. Compared with those having a low nutrition literacy score (below median), those with a high score were less likely to be overweight and obese. The odds ratio (95% CI) for overweight was 0.87 (0.79–0.97) (nutrition literacy) and 0.81 (0.73–0.90) (functional nutritional literacy). The corresponding figures for obesity were 0.84 (0.77–0.91) and 0.73 (0.67–0.80), respectively. Significant interaction existed between grade and nutrition literacy. The inverse association between nutrition literacy and overweight/obesity was significant among those in senior school but not among those in junior high school.

Conclusion

Nutrition literacy was inversely associated with overweight/obesity among adolescents, especially those attending senior high schools.

Sociocultural, health knowledge, and health literacy among children ages 9-10 years in Thailand

BACKGROUND

Health literacy (HL) enables a person to make good decisions regarding health care, disease prevention, and health promotion to maintain and improve health. In Thailand, most existing studies focus on adults' HL rather than children. This research aimed to determine the influence of sociocultural and health knowledge on HL among children ages 9-10 years in Thailand.

MATERIALS AND METHODS

A cross-sectional study was conducted among 1650 children aged 9-10 years. The respondents were recruited using multistage random sampling from 39 primary schools of 13 provinces in all four regions of Thailand. A self-administered structured questionnaire was used to collect the required data. The multilevel analysis was used to determine the association between sociocultural, health knowledge, and HL while controlling the effects of covariates. The result was presented as adjusted odd ratios and its 95% confidence interval (CI).

RESULTS

Of the total 1650 respondents, 86.24% (95% CI: 84.49%-87.82%) had adequate and excellent levels of HL. The multivariable analysis indicated factors that were significantly associated with adequate and excellent levels HL including adequacy of per diem (adjusted odds ratio [adj. OR] = 6.78; 95% CI: 3.54-12.97) and had good relationship with teachers (adj. OR = 2.19; 95% CI: 1.55-3.09). Sources of health education which were received health education from parents (adj. OR = 3.51; 95% CI: 2.39-5.14), from teachers (adj. OR = 2.03; 95% CI: 1.43-2.89), and from the Internet (adj. OR = 1.83; 95% CI: 1.12-2.99) were also significantly associated with HL. Another significant factor was had good level of health knowledge (adj. OR = 1.86; 95% CI: 1.30-2.66) when control clustering effect of region, provinces, school, and classroom size.

CONCLUSIONS

More than 85% of children ages 9-10 years in Thailand had adequate and excellence levels of HL. Sociocultural and health knowledge had influence on children HL.

A Visualized and Scientometric Analysis of Health Literacy Research

Purpose

The health literacy concerned by numerous policy and advocacy organizations is springing up rapidly and has evolved substantially over the past few decades. During the period of COVID-19, people who are in the absence of effective treatment and limited availability of vaccination need a higher health literacy to protective themselves. In order to provide a summary of the health literacy research, a visualized and Scientometric analysis is applied in this study.

Methods

Based on a scientific review of 3,670 data on health literacy from Web of Science, this research uses Citespace software to systematically and objectively describe health literacy to determine the knowledge evolution structure between articles and investigate research trends.

Results

The results show that the annual outputs of publications have grown rapidly since 2003. The USA and Australia make larger contributions compared with other countries in terms of quantity of publications and worldwide collaboration relationship between them. The “Soc Sci Med,” “J Health Commun.” “Patient Educ Couns” and “J Gen Intern Med” pay more attention to health literacy research. The leading authors with influence and authority are Wolf MS, Osborne RH, and Paasche-Orlow MK. Health literacy research in this field focuses on care, knowledge, and education, and so on. An emerging trend of health literacy with Covid-19, online tools, nursing, and obesity will spread across the globe.

Conclusion

Compared with simply reviewing existing articles, the major contribution in this study is a comprehensive review of yearly scientific output, journals, countries, institutions, contributors, highly cited papers, and keywords for health literacy research. The review also provides valuable and seminal guidelines for interested researchers on health literacy research.

The association between body mass index and health literacy in high school Students: A cross-sectional study

BACKGROUND

Obesity and overweight in children and adolescents have become a global problem in recent years. Adolescence increases the likelihood of obesity in adulthood and associated illnesses. Nowadays, health literacy is one of the greatest determinants of the health. This study was conducted to evaluate the correlation between body mass index (BMI) and health literacy in high school students.

MATERIALS AND METHODS

In this descriptive-analytical study, 430 high school students were enrolled in a multi-stage random method in Yazd city in the center of Iran. The data were collected through The Health Literacy Measure for Adolescents and calculate BMI with measurement of height and weight of adolescents. The data were then analyzed using SPSS 25 and descriptive and inferential statistics (Chi-square and multivariate regression).

RESULTS

The results showed that the mean score of BMI (21.76 ± 3.76) was in a normal range. The score of health literacy was at the borderline level (58.44 ± 13.79). BMI was not significantly correlated with health literacy (P = 0.09). BMI was significantly different in terms of age, high school grade, school type, and health status. School type and health status predict 37% of the variance of BMI (R 2 = 37%) and the best predictor was health status (P < 0.05).

CONCLUSIONS

The results of the present study showed that BMI was not correlated with health literacy and student health literacy was at the borderline level. It is necessary to carry out further studies on the causes and facilitators and the barriers to increasing health literacy. Furthermore, educational interventions are needed to prevent the increase of BMI in adolescents and identify determining factors.

Exploring the design and introduction of the Ophelia (Optimising Health Literacy and Access) process in the Philippines: A qualitative case study

ISSUE ADDRESSED

The Ophelia (Optimising Health Literacy and Access) process is a systematic approach for improving access to health information and services through health literacy interventions. However, there is limited understanding of how this process can be adapted in low- and- middle-income countries.

METHODS

A qualitative case study was used to describe how an Ophelia project was designed and introduced in a community setting in the Philippines and to explore the experiences of stakeholders involved in this process. Two qualitative methods were used: document analysis (n = 12) and semi-structured interviews (n = 12).

RESULTS

Data showed that the project stakeholders had embedded the eight Ophelia principles in the design of the project, introduced the Ophelia process in one target community, and conducted a health literacy needs assessment. Project stakeholders faced challenges engaging with local authorities and community members in this location, but overcame these issues through building relationships and understanding their needs. Local authorities and stakeholders provided access to resources and knowledge of this target community.

CONCLUSIONS

The Ophelia process can be adapted for a community setting in the Philippines. Understanding local communities is crucial for introducing and engaging participation in this process. SO WHAT?: The Ophelia process may have implications for increasing access to health information and services for vulnerable populations in the Philippines and the Asia Pacific.

Low Health Literacy Is Associated With Energy-Balance-Related Behaviors, Quality of Life, and BMI Among Rural Appalachian Middle School Students: A Cross-Sectional Study

BACKGROUND

Many studies document associations between low health literacy (HL) and poor health behaviors and outcomes. Yet, HL is understudied among adolescents, particularly from underserved, rural communities. We targeted rural adolescents in this cross-sectional study and explored relationships between HL and (1) energy-balance-related health behaviors and (2) body mass index (BMI) and quality of life (QOL).

METHODS

Surveys were administered to 7th graders across 8 middle schools in rural Appalachia. HL was assessed using the Newest Vital Sign. Energy-balance-related behaviors and QOL were assessed using validated instruments. Height and weight were objectively measured. Analyses were conducted using the Hodges-Lehmann nonparametric median difference test.

RESULTS

Of the 854 adolescent students (mean age = 12; 55% female), 47% had limited HL. Relative to students with higher HL, students with lower HL reported significantly lower frequency of health-promoting behaviors (water, fruit and vegetable intake, physical activity, sleep), higher frequency of risky health behaviors (sugar-sweetened beverages, junk food, screen time), and had higher BMI percentiles and lower QOL (all p < .05).

CONCLUSIONS

Low HL is associated with energy-balance-related behaviors, BMI, and QOL among rural, Appalachian adolescents. Findings underscore the relevance of HL among rural middle school students and highlight implications for school health.

Nutrition-Exercise Behaviors, Health Literacy Level, and Related Factors in Adolescents in Turkey

BACKGROUND

Health behaviors of adolescents affect their health and well-being into adulthood. This study was conducted to determine the nutrition-exercise behaviors, health literacy level, and related factors in adolescents.

METHODS

A cross-sectional design was used for this study. Overall, 810 students in grades 6-8 in a Turkish school completed the study. A personal information form, the Nutrition-Exercise Behaviors Scale, and the Health Literacy for School-Aged Children Scale were used for data collection.

RESULTS

According to the mean score of the Health Literacy Scale, 21% of the students had a low level of health literacy, 63.8% had a medium level, and 15.2% had a high level. A positive correlation was found between health literacy level and healthy nutrition-exercise behavior (r = 0.345, p < .001), and a positive correlation between health literacy level and meal pattern (r = 0.230, p < .001). A positive correlation (r = 0.385, p < .001) was found between meal pattern and healthy nutrition-exercise behavior. A moderate positive correlation (r = 0.510, p < .001) was found between unhealthy nutrition-exercise behavior and psychological/addicted eating behavior.

CONCLUSION

The present study revealed that nutrition-exercise behaviors and the health literacy of adolescents were at a moderate level and, there was a relationship between nutrition-exercise behaviors and health literacy levels in adolescents. Interventions should be planned and followed through with parents to help adolescents adopt healthy nutrition and exercise behaviors from an early age and to increase their health literacy level. In this context, it is recommended to implement training and intervention programs for adolescents and their families.

Child-Centred Health Dialogue for primary prevention of obesity in Child Health Services - a feasibility study

Aims: The aim of this study was to test a Child-Centred Health Dialogue model for primary prevention of obesity for 4-year-old children in Child Health Services, for its feasibility and the responsiveness of its outcomes. Methods: A feasibility study was set up with a non-randomised quasi-experimental cluster design comparing usual care with a structured multicomponent Child-Centred Health Dialogue consisting of two parts: (1) a universal part directed to all children and (2) a targeted part for families where the child is identified with overweight. Results: In total, 203 children participated in Child-Centred Health Dialogue while 582 children received usual care. Nurses trained in the model were able to execute both the universal health dialogue and the targeted part of the intervention. Tutorship enabled the nurses to reflect on and discuss their experiences, which strengthened their confidence and security. One year after the intervention fewer normal-weight 4-year-olds in the intervention group had developed overweight at the age of five compared with the control group, and none had developed obesity. The difference in overweight prevalence at follow-up did not reach statistical significance. Conclusions: This study demonstrates that a child-centred, multicomponent, interactive intervention for the promotion of healthy lifestyles and primary prevention of obesity for all 4-year-old children participating in Child Health Services is feasible on a small scale. As almost all caregivers make use of Child Health Services in Sweden, the findings should be confirmed in a randomised controlled trial before the intervention can be implemented on a larger scale.

What Role Does Body Image in Relationship between Level of Health Literacy and Symptoms of Eating Disorders in Adolescents?

(1) Background: The aim of this study was to explore the associations between health literacy and symptoms for eating disorders among adolescents, taking into consideration age and gender and whether this association is mediated by body image. (2) Methods: We used data on 5054 adolescents (mean age = 13.9, 51.7% boys) from the Health Behaviour in School-Aged Children study conducted in 2018 in Slovakia. We used logistic regression models to examine associations between level of health literacy and symptoms for eating disorders mediated by body image. (3) Results: Adolescents with low and medium levels of health literacy had a higher occurrence of reporting two or more symptoms of eating disorders (odds ratio (OR)/95% CI: 2.25/1.78-2.84 and 1.37/1.15-1.65). Adjustment for body image reduced the significance of association between low level of health literacy and symptoms for eating disorders by 26.4%, and association between medium level of health literacy and symptoms for eating disorders by 29.7%. (4) Conclusions: Adolescents who have a low health literacy level were found to have a higher probability of having symptoms for eating disorders, especially when they perceive themselves as fat. The study refers to potential theoretical frameworks for health literacy intervention that may provide guidelines for the intervention design and materials.

The Status of Health Literacy in Students Aged 6 to 18 Old Years: A Systematic Review Study

Background

Adolescents and children are a core target population for health literacy (HL) studies and practice. There is limited knowledge regarding the HL skills and abilities that help young people and children in making health decisions. This study aimed to evaluate the status of HL in ongoing school students.

Methods

Literature searching was performed using nine databases (Web of Science, PubMed, Scopus, Google Scholar, Iranmedex, Magiran, Scientific Information Database) without restriction in time until January 2019, and database searches were supplemented with reference hand searches and gray literature. Cross-sectional and experimental studies with focuses on validated measures of HL in ongoing students were included.

Results

This systematic review of identified 17 studies and 199714 samples specifically studied on ongoing school students aged 6-18 years. Students and their mothers have a moderate level of HL in four dimensions of menstrual health, physical activity, breast self-test, and iron deficiency anemia, and most of them have a high level of HL only in terms of nutrition. The relationship of HL with health outcomes, health promotion behaviors, self-efficacy, self-mutilating behaviors, and self-care abilities was statistically significant. HL status is related to parents' education level, socio-economic determinants (culture, family income, and environmental contextual factors), age groups, and media/digital communication channels.

Conclusion

This review identified seven main determinates that significantly affect HL status in the target group. This systematic review shows most of the ongoing school students had an inadequate level of HL skills. HL strategies have a potential impact on improving students' health behaviors and life quality.

Health literacy as a determinant of childhood and adult obesity: a systematic review

OBJECTIVES

To assess whether Health Literacy (HL) acts as a determinant of obesity in adults and children by synthesizing the results of recent scientific evidence.

CONTENT

This is a systematic qualitative review following the MOOSE guidelines. A systematic, computer-assisted literature search via PubMed scientific database, between January 1st, 2000, and September 30th 2020, was conducted. Only cross-sectional epidemiologic research studies that were published in the English language, investigating HL's possible role as a determinant of childhood and adult obesity, were included.

SUMMARY

After screening 725 citations from the PubMed database, 39 (n=39) studies in total were included in this literature review; Four (n=4) studies were conducted in the children population, seven (n=7) studies were performed in children-parent/caregiver dyads, and 28 studies (n=28) enrolled adults. There is significant evidence that HL knowledge and skills determine the consequent management of obesity and BMI rates in children and adult populations.

OUTLOOK

Despite policies and action plans put in place by countries globally, overweight and obesity continue to be a pressing public health issue and one of the critical drivers of non-communicable diseases, constituting a health, social and economic burden worldwide. Health Literacy as an essential health policy and promotion agenda item and a critical empowerment strategy could increase children's and adults' control over their overall health and awareness to overcome obesity issues. Initiatives to improve HL levels could be useful tools in managing the obesity epidemic, starting from integrating HL in the school curriculum and further in family and community action plans.

Inverse Association Between Health Literacy and Obesity Among Children in Greece: A School-Based, Cross-Sectional Epidemiological Study

Children's health literacy is a crucial pillar of health. This study is aimed to examine the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. A population-based, cross-sectional observational study enrolling 1,728 students (795 boys), aged 10 to 12 years old, was conducted during school years 2014-2016. A health literacy index (range 0-100) was created through an item response theory hybrid model, by combining a variety of beliefs and perceptions of children about health. The mean health literacy score was 70.4 (±18.7). The majority of children (63.8%) had a "high" level (i.e., >67/100) of health literacy, 30.5% had a "medium" level (i.e., 34-66/100) of health literacy, while a small proportion of children (5.7%) had a "low" level (i.e., <33/100). Girls exhibited a higher level of health literacy than boys (71.7 ± 18.3 vs. 68.8 ± 19.1, p < .01). Regarding body weight status, 21.7% of children was overweight and 5.0% was obese. Linear regression models showed that the health literacy score was inversely associated with children's body mass index (regression coefficient [95% CI]: -0.010 [-0.018, -0.001]), after adjusting for dietary habits, physical activity levels, and other potential confounders. Health literacy seems to be a dominant characteristic of children's weight status; therefore, school planning, as well as public health policy actions should emphasize on the ability of children's capacity to obtain, process, and understand basic health information.

A causal relationship model of health literacy and health behavior for obesity prevention among primary school students in Bangkok, Thailand

Background: The aim of the study was to develop a research instrument to study the levels of health literacy for obesity prevention (HLFOP), as well as health behavior for obesity prevention (HBFOP). In addition, we investigated the causal relationship model between health literacy and health behavior for obesity prevention among primary school students in Bangkok, Thailand. Methods: A cross-sectional study among 600 participants who were primary school students (aged 9-13 years) was conducted. The participants were selected from schools in all parts of Bangkok using multi-stage random sampling technique. The research instrument to assess HLFOP and HBFOP, constructed by the researchers, were utilized for data collection. Data were analyzed using descriptive statistics, exploratory and confirmatory factor analyses, and structural equation model through linear structural relationship. Results: We found that HBFOP was directly influenced by heath literacy in the category of Critical Literacy with an effect size of 0.65 (p < 0.01), and was indirectly influenced in the category of Basic Literacy and Interactive Literacy through Critical Literacy with effect sizes of 0.46 and 0.58 (p<0.01), respectively. The model was consistent with the empirical data, with Chi-Square=13.68, df=7, p=0.05721, RMSEA (root mean square error of approximation)= 0.040,  SRMR (standardized root mean square residual)= 0.017 NFI (normal fit index)=0.99, GFI (goodness of fit index)=0.99, and AGFI (adjusted goodness of fit index)=0.97. Conclusions: HLFOP was influential on HBFOP in primary school students in the Bangkok Metropolis. The categories that were particularly influential were: 1) Basic Literacy: accessing health information skills; 2) Interactive Literacy: communication skills; and 3) Critical Literacy: media literacy and self-management skills.

Health Literacy and Predictors of Body Weight in Turkish Children

PURPOSE

This study assessed the association between health literacy (both of children and their parents) and body weight in Turkish schoolchildren. This study also aimed to determine the predictors of body weight in children.

DESIGN AND METHODS

This was a descriptive, correlational study that enrolled students and their parents from Turkish secondary schools. Data were collected using the Health Literacy Scale for School-Aged Children, Adult Health Literacy Scale, socio-demographic questionnaires and anthropometric measurements.

RESULTS

The mean child age was 12.76 ± 1.27; 40.2% were male, 41.5% had higher health literacy and 17.2% were obese. Child health literacy did not correlate with body mass index (r = 0.04, p > 0.05), but correlated positively with parent health literacy (r = 0.17, p < 0.05). Parent body mass index was the only explanatory variable in child body mass index.

CONCLUSIONS

Obesity in schoolchildren correlates with parental obesity. The results showed parents should participate in practising strategies that aim to prevent and treat childhood obesity.

PRACTICE IMPLICATIONS

Children's health literacy skills can be improved to develop their health and academic achievements.

Moving Health Literacy Research and Practice towards a Vision of Equity, Precision and Transparency

Over the past two decades, health literacy research has gained increasing attention in global health initiatives to reduce health disparities. While it is well-documented that health literacy is associated with health outcomes, most findings are generated from cross-sectional data. Along with the increasing importance of health literacy in policy, there is a lack of specificity and transparency about how to improve health literacy in practice. In this study, we are calling for a shift of current research paradigms from judging health literacy levels towards observing how health literacy skills are developed over the life course and practised in the real world. This includes using a life-course approach, integrating the rationale of precision public health, applying open science practice, and promoting actionable knowledge translation strategies. We show how a greater appreciation for these paradigms promises to advance health literacy research and practice towards an equitable, precise, transparent, and actionable vision.

Making a Case for "Education for Health Literacy": An International Perspective

In many countries, health literacy research, practice, and policy have been moving away from a focus only on medical care and health-care settings to a much broader conceptualization. In this broader perspective, health literacy can be obtained and used across many other settings (e.g., school, home, workplaces, government) towards achieving health and wellness goals across the life-course for individuals, families, and communities. The education sector is a critical domain towards these achievements and education for health literacy is a fundamental process and outcome. This can help towards important public health goals, including critical health literacy, as oriented not only towards individual actions, but also towards supporting effective social and political action. This Perspective Article describes the importance and utility of the education for health literacy perspective, which, follows a view that health literacy is a key outcome of health education from which improved population health, health promotion and disease prevention could be achieved across diverse contexts. We first describe different educational paradigms to address health literacy and clarify the education for health literacy perspective as a supportive, instructional and capacity-building global resource across the life-course. Then, using specific examples from Canada, America, and Germany, we provide a snapshot of the diverse ways in which the education for health literacy perspective can be found in national policies. These include broad national goals and standards (Germany and Canada) and major health care reform (America). We next consider the tensions and gaps that can arise in the translation and implementation of these policies relative to the ideal education for health literacy perspective, especially related to equity. These include the need for funding, goals of the educational system, and limited evaluation of policy in practice. Finally, we highlight strategic opportunities to achieve education for health literacy and equity especially offering examples from innovative practice in Canada across the lifespan.

School education and childhood obesity: A systemic review

Childhood obesity prevalence is shooting up at a phenomenal rate worldwide, leading to long-term devastating consequences. A great number of studies have investigated factors contributing to the increase in BMI of children and adolescents. School-based, home-based and clinic-based solutions have been suggested as possible viable strategies, among which school-based interventions is believed to produce a noticeable effect on a massive scale. However, the question of whether school interventions, especially school education exert significant impact on childhood obesity or not, is left with mixing results. This article aims to holistically review the relationship between school education and childhood obesity. Various factors are covered, including health education, nutrition education, school nutrition, physical education, teachers' awareness, teaching practice and school stress, In all, school education is not the answer to childhood obesity but just part of it. More attempts from other stakeholders (parents, community, policy makers, researchers, etc.) should be made in order to solve this complicated puzzle.

The impact of self-efficacy and health literacy on outcome after bariatric surgery in Sweden: a protocol for a prospective, longitudinal mixed-methods study

INTRODUCTION

A person-centred approach, to know about a person's individual weaknesses and strengths, is warranted in today's healthcare in Sweden. When a person suffers from obesity, there are not only risks for comorbidities but also increased risk for decreased health-related quality of life (HRQoL). After bariatric surgery, there are also risks for complications; however, healthcare service expects the person to have sufficient ability to handle recovery after surgery. The need is to investigate how a person's self-efficacy and health literacy(HL) skills are important to determine their effect on recovery as well as HRQoL after bariatric surgery. It can, involve the person in the care, improve shared decision-making, and perhaps decrease complications and readmissions.

METHOD AND ANALYSIS

This is a prospective, longitudinal mixed-methods study with the intent of including 700 patients from three bariatric centres in Sweden (phase 1); 20 patients will be included in a qualitative study (phase 2). Inclusion criteria will be age >17 years, scheduled primary bariatric surgery and ability to read and understand the Swedish language in speech and in writing. Inclusion criteria for the qualitative study will be patients who reported a low self-efficacy, with a selection to ensure maximum variation regarding age and gender. Before bariatric surgery patients will answer a questionnaire including 20 items. Valid and reliable instruments will be used to investigate general self-efficacy (10 items) and functional and communicative and critical HL (10 items). This data collection will then be merged with data from the Scandinavian Obesity Surgery Registry. Analysis will be performed 30 days, 1 year and 2 years after bariatric surgery. One year after bariatric surgery the qualitative study will be performed. The main outcomes are the impact of a person's self-efficacy and HL on recovery after bariatric surgery.

ETHICS AND DISSEMINATION

The study has received approval from the ethical review board in Uppsala, Sweden (number 2018/256). The study results will be disseminated through peer-reviewed publications and conference presentations to the scientific community and social media.

Health Literacy: Current Status and Challenges in the Work of Family Doctors in Bosnia and Herzegovina

Health literacy (HL) has become an important area of research. The aim of this study was to evaluate the HL of primary healthcare patients in the Republic of Srpska (RS), Bosnia and Herzegovina (B&H) and to identify socioeconomic and health factors associated with HL. This cross-sectional study among 768 patients was conducted in two healthcare centres between March and May 2017, using the Short Test of Functional Health Literacy in Adults (S-TOFHLA). Analysis was done using descriptive and inferential statistics (a chi-squared test and logistic regression). Inadequate and marginal HL was found in 34,6% of respondents. Socioeconomic and self-reported health factors were significantly related to HL. An age of 55 years and over (OR 1.02), living in a rural environment (OR 2.25), being divorced (OR 3.32), being insufficiently physically active (OR 1.29), having poor income (OR 1.96), having more than three chronic diseases (OR 1.94), and poor health (OR 1.59) were significantly corelated with inadequate and marginal HL. The results of our study indicate that a low level of HL is related to the elderly, having a divorce, having a rural residence, poor income, having more than three chronic diseases, poor health, and insufficient physical activity. Further evaluation, monitoring, and activities to improve HL are of great importance for patients’ health outcomes.

Low health literacy and excess body weight: a systematic review

OBJECTIVE

There is recent evidence that poor health literacy (HL) could be implicated in the aetiology of obesity and could be an important reason behind obese people's inability to encounter difficulties in overcoming obesity issues. The current study reviews the recent scientific evidence investigating the possible link between poor HL levels and excess body weight in adults and children.

METHODS

The authors performed a thorough systematic computer-assisted literature search from 1 January 2005 up to 31 May 2017. Only English original studies in healthy people, investigating the relationship between HL and excess body weight, were included.

RESULTS

Twenty-two studies in total were included in this literature review, 17 studies were conducted in adults and 5 in children. In 17 out of 22 studies reviewed, low HL was significantly associated with increased body mass index, overweight and obesity. In case of children and adolescents, the above association seems to be more consistent compared to adults.

CONCLUSION

There is good evidence that low levels of HL are associated with excess body weight, particularly in children. Initiatives to improve health literacy levels could be a useful tool in the management of the obesity epidemic.

How Well Do Children Understand the Vocabulary of Sleep?

BACKGROUND

Sleep surveys, such as the Pediatric Daytime Sleepiness Scale (PDSS), are used to determine a variety of concerns associated with sleep, including excessive daytime sleepiness (hypersomnolence), bedtime sleep behaviors, night awakenings, sleep duration, and sleep-disordered breathing. However, the literacy ability of the patient may not be adequate to ensure comprehension of questions and provision of accurate responses.

OBJECTIVE

To assess children's understanding of the sleep-associated vocabulary included in the PDSS.

METHODS

A cross-sectional, open-response survey was developed for use with students age 4 to 12 years. Prior to completing the instrument, each student was asked the meaning of six key sleep-related words used in the PDSS: drowsy, sleepy, alert, awakened, tired, and awake. The parents/caregivers were requested to record their child's definitions of these key words exactly as stated. Identification of words for "suitable" definitions was undertaken through consultation of three online dictionaries. This enabled the qualitative process associated with open-response surveys to be followed: identification of common themes, chunking of information, and criteria for coding responses. The final sample consisted of word definitions from 325 students (152 boys and 173 girls) from a school enrollment of 727 (45%).

KEY RESULTS

A high percentage of children provided "suitable" responses for the words sleepy (84%) and tired (75%). The percentage of "suitable" responses for the words drowsy and awakened gradually increased across the age groups. The words alert and awake were challenging for the children to define, with the sleep-associated definition for alert only being provided by 31% of children overall and awake only being provided by 48% overall. In total, 57% of children were able to provide suitable definitions for at least four words.

CONCLUSIONS

Our findings suggest that the results of many sleep surveys using these terms may not yield results that accurately reflect a child's actual state of daytime sleepiness and sleep/wake behaviors. Prior to administering a sleep survey, physicians need to clearly explain the meanings of sleep-associated words used in the survey and thus gain a more accurate reflection of a child's sleep and daytime behaviors. [HLRP: Health Literacy Research and Practice. 2019;3(1):e53-e69.].

PLAIN LANGUAGE SUMMARY

Sleep surveys are used to identify problems with sleep. Children with poor health literacy due to age may not understand the questions and may not provide adequate answers. Children's understanding of sleep-associated vocabulary was assessed using six words: drowsy, sleepy, alert, awakened, tired, and awake. Many of these words were found to be difficult for the children to define.

Comprehensive Health Literacy and Health-Related Behaviors Within a General Japanese Population: Differences by Health Domains

The present study aimed to explore how different health-related domains of health literacy, as measured by the European Health Literacy Survey Questionnaire, were associated with health-related behaviors among a general population in Japan. We conducted a cross-sectional observational study of 1002 Japanese residents. Our questionnaire addressed socioeconomic status, health status, health-related behaviors, and health literacy. Among the 3 health-related domains of health literacy (health care, disease prevention, and health promotion), a multivariate model revealed that the disease prevention domain was associated with exercise behavior and alcohol consumption. The health promotion domain was associated with dietary behavior and exercise behavior. There were strong correlations among all health-related domains of health literacy; however, there were different associations between health literacy and health-related behaviors depending on those domains. Additional research is needed to determine how and to what extent each domain of health literacy is related to what health behaviors and outcomes.

Improvement of health literacy and intervention measurements among low socio-economic status women: findings from the MyBFF@home study

Background

Health literacy (HL) consists of different components and associates with several health outcomes, including obesity. It is linked to an individual’s knowledge, motivation, competencies, behavior, and application to everyday life. The present study aimed to determine the change of HL scores and to investigate the difference of intervention outcomes at the weight loss (WL) intervention and WL maintenance phase between the HL groups.

Methods

A total of 322 participants from the MyBFF@home study completed the Newest Vital Sign (NVS) test at baseline. However, only data from 209 participants who completed the NVS test from baseline to WL intervention were used to determine the HL groups. Change of the NVS scores from baseline to WL intervention phase was categorized into two groups: those with HL improvement (increased 0.1 score and above) and those without HL improvement (no change or decreased 0.1 score and more). Independent variables in this study were change of energy intake, nutrient intake, physical activity, anthropometry measurements, and body composition measurements between baseline and WL intervention as well as between WL intervention and WL maintenance. An Independent sample t-test was used in the statistical analysis.

Results

In general, both intervention and control participants have low HL. The study revealed that the intervention group increased the NVS mean score from baseline (1.19 scores) to the end of the WL maintenance phase (1.51 scores) compared to the control group. There was no significant difference in sociodemographic characteristics between the group with HL improvement and the group without HL improvement at baseline. Most of the dietary intake measurements at WL intervention were significantly different between the two HL groups among intervention participants. Physical activity and body composition did not differ significantly between the two HL groups among both intervention and control groups.

Conclusion

There was an improvement of HL during the WL intervention and WL maintenance phase in intervention participants compared to control participants. HL shows positive impacts on dietary intake behavior among intervention participants. New research is suggested to explore the relationship between HL and weight loss behaviors in future obesity intervention studies.

Health literacy and self-rated health in adults primary care patients

Purpose To verify the association between health literacy, social determinants and self-rated health in adult's primary health care patients. Methods this is an Observational cross-sectional study in which a total of 380 patients of the Unified Health System in the context of primary health care were interviewed. The sample was probabilistic, stratified by gender, age, and Basic Health Unit. Health literacy was evaluated by an instrument of analysis of the perception of adults about the understanding of health orientations and possible difficulties in this process (Health Literacy Scale). Descriptive and association analyses were performed (Pearson's chi-square test, p≤0.05). Results It was verified that the majority of the interviewees belongs to classes C1 and C2 and attended high school (complete or incomplete). Regarding self-rated health, to be considered healthy and with good health were the predominant perceptions. In the Health Literacy Scale, it was verified that most patients reported never presenting difficulties in the situations of this instrument, except understanding written orientations. It was observed the association with a statistical significance of the better perception of health literacy with higher educational level and economic classification, as well as with self-rated of good health. Conclusion There was a statistical association between health literacy, social determinants, and self-rated health in the analyzed adults. It is noteworthy the contribution of the Health Literacy Scale for emphasizing the perception of difficulties in everyday health situations. It is necessary to develop dialogic relationships that build more robust communication processes between professionals and healthcare patients to favor health literacy skills.

Factors associated with health literacy in multimorbid patients in primary care: a cross-sectional study in Switzerland

OBJECTIVE

To identify factors associated with health literacy in multimorbid patients.

DESIGN

A nationwide cross-sectional study in Switzerland. Univariate and multivariate linear regressions were calculated to identify variables associated with health literacy. A multiple imputation approach was used to deal with missing values.

PARTICIPANTS

Multimorbid patients recruited in primary care settings (n=888), above 18 years old and suffering from at least 3 of 75 chronic conditions on a predefined list based on the International Classification of Primary Care 2.

MAIN MEASURES

Health literacy was assessed using the European Health Literacy Survey project questionnaire (HLS-EU 6). This comprises six items scored from 1 to 4 (very difficult=1, fairly difficult=2, fairly easy=3, very easy=4), and the total health literacy score is computed as their mean. As we wished to understand the determinants associated with lower health literacy, the HLS-EU 6 score was the only dependent variable; all other covariates were considered independent.

RESULTS

The mean health literacy score (SD) was 2.9 (0.5). Multivariate analyses found significant associations between low health literacy scores and treatment burden scores (β=-0.004, 95% CI -0.006 to 0.002); marital status, predominantly the divorced group (β=0.136, 95% CI 0.012 to 0.260); dimensions of the EuroQuol 5 Dimension 3 Level (EQ5D3L) quality of life assessment, that is, for moderate problems with mobility (β=-0.086, 95% CI -0.157 to 0.016); and with moderate problems (β=-0.129, 95% CI -0.198 to 0.060) and severe problems with anxiety/depression (β=-0.343, 95% CI -0.500 to 0.186).

CONCLUSIONS

Multimorbid patients with a high treatment burden, altered quality of life by problems with mobility, anxiety or depression, often also have low levels of health literacy. Primary care practitioners should therefore pay particular attention to these patients in their daily practice.

Assessment of health literacy with the Newest Vital Sign and its correlation with body mass index in female adolescent students

Background One of the significant outcomes of health education is health literacy (HL), which should be expanded to improve health promotion. Objective The aim of this study was to assess HL and its relationship with Body Mass Index (BMI) in female adolescent students. Subjects This study was conducted on 235 female students (aged 13-15 years) which were selected with cluster sampling. Methods For assessing HL, the Newest Vital Sign (NVS) was used and BMI Z-score was evaluated following the World Health Organization (WHO) guidelines. Data were analyzed using SPSS version 16. Results Based on this study's results, 11.5%, 37% and 51.5% of adolescents had adequate HL, limited HL and inadequate HL, respectively. There was a negative correlation between adolescents HL and BMI, rs = -0.233 (p < 0.001). Conclusion Most of adolescents had limited HL and students with higher BMI had a worse HL score. As a matter of fact, as adequate HL has a significant role for promoting health in the society policy makers must design educational programs for adolescents especially in non-medical settings such as schools where adolescents spend most of their time.

Dissecting and customising the Childhood Obesity Prevention Advisory Council (COPAC): the development and application of a community engagement framework to improve childhood obesity prevention among migrant populations

Background: Migrant communities in Australia bear a disproportionate childhood obesity burden. They also show poor engagement in obesity prevention initiatives which may contribute to widening obesity disparities. Community engagement has been shown to be effective in reducing health disparities by improving migrant communities’ participation in prevention programmes.

Objective: This study aimed to develop a community engagement framework to improve childhood obesity prevention among migrants.

Design: Based on the African Review Panel model and the Community-Based Participatory Research conceptual logic model, the Childhood Obesity Prevention Advisory Council (COPAC) framework was developed and established in four disadvantaged areas in Victoria, Australia. The COPAC included service providers and migrant community members from the same project’s site.

Results: COPAC demonstrated several benefits including cross-organisational and multidisciplinary collaborations; understanding of the cultural barriers in childhood obesity prevention; enthusiasm from the COPAC members in addressing childhood obesity in their multicultural communities; equitable involvement, motivation, and empowerment of COPAC members in research development; and establishing organisational affiliations to foster long-term community involvement. This study also documented several challenges in community engagement including lack of prioritisation of migration-related childhood obesity disparities by the policymakers; staffing constraints among service providers leading to frequent disruptions in COPAC members’ contributions; and lack of adequate training and skill-building of bicultural workers.

Conclusions: The COPAC model adopted a flexible and dynamic community engagement process to suit the ongoing needs of the migrant community which incorporated the existing talents and resources within the community. For effective community engagement of migrant communities, it is important for policymakers to develop the knowledge, capacity and skills of the bicultural migrant workforce. Integrating both service providers and migrant community members in the COPAC has demonstrated that a multifaceted community-led approach has the potential to reduce childhood obesity-related disparities in Australia.

Trauma injury in adult underweight patients: A cross-sectional study based on the trauma registry system of a level I trauma center

The aim of this study was to investigate and compare the injury characteristics, severity, and outcome between underweight and normal-weight patients hospitalized for the treatment of all kinds of trauma injury.This study was based on a level I trauma center Taiwan.The detailed data of 640 underweight adult trauma patients with a body mass index (BMI) of <18.5 kg/m and 6497 normal-weight adult patients (25 > BMI ≥ 18.5 kg/m) were retrieved from the Trauma Registry System between January 1, 2009, and December 31, 2014. Pearson's chi-square test, Fisher's exact test, and independent Student's t-test were performed to compare the differences. Propensity score matching with logistic regression was used to evaluate the effect of underweight on mortality.Underweight patients presented a different bodily injury pattern and a significantly higher rate of admittance to the intensive care unit (ICU) than did normal-weight patients; however, no significant differences in the Glasgow Coma Scale (GCS) score, injury severity score (ISS), in-hospital mortality, and hospital length of stay were found between the two groups. However, further analysis of the patients stratified by two major injury mechanisms (motorcycle accident and fall injury) revealed that underweight patients had significantly lower GCS scores (13.8 ± 3.0 vs 14.5 ± 2.0, P = 0.020), but higher ISS (10.1 ± 6.9 vs 8.4 ± 5.9, P = 0.005), in-hospital mortality (odds ratio, 4.4; 95% confidence interval, 1.69-11.35; P = 0.006), and ICU admittance rate (24.1% vs 14.3%, P = 0.007) than normal-weight patients in the fall accident group, but not in the motorcycle accident group. However, after propensity score matching, logistic regression analysis of well-matched pairs of patients with either all trauma, motorcycle accident, or fall injury did not show a significant influence of underweight on mortality.Exploratory data analysis revealed that underweight patients presented a different bodily injury pattern from that of normal-weight patients, specifically a higher incidence of pneumothorax in those with penetrating injuries and of femoral fracture in those with struck on/against injuries; however, the injury severity and outcome of underweight patients varied depending on the injury mechanism.
