Relationship between health literacy and quality of life among cancer survivors in China: a cross-sectional study

Quality of life among French breast cancer survivors in comparison with cancer-free women: the Seintinelles study

BACKGROUND

Health-Related Quality of life (HRQoL) in cancer survivors can be significantly affected in the long-term by various consequences resulting from differing levels of severity of cancer and its treatments. Our objective was to identify factors associated with HRQoL in breast cancer survivors (BCSs) and cancer-free women (CFWs).

METHODS

We conducted a cross-sectional study in Seintinelles volunteers who answered online questionnaires between September 15, 2020 and February 5, 2021. HRQoL was measured using the World Health Organization Quality of Life-BREF questionnaire. We collected data on sociodemographic and health-related factors, lifestyle habits, coping mechanisms, locus of control, and health literacy. SAS version 9.4 statistical software was used for analyses. We performed descriptive analyses of the characteristics of the participants in each group and compared these characteristics between the two groups using the Chi2 test or the Student t-test. The adjusted means of the scores of different psychometric scales were calculated and compared using the method of least squares to fit general linear models (GLM) while adjusting for various factors. Multiple linear or multiple logistic regression models were used to assess the factors associated with WHOQOL-BREF scores, separately, in the two groups of participants.

RESULTS

The study involved 722 BCSs and 1359 CFWs aged 26-75 years. BCSs had significantly lower physical health scores and were less likely to be satisfied with their health compared to CFWs (59.5 vs. 63.2, p < 0.0001; and 56.5% vs. 75.2%, p = 0.002, respectively). In both groups, some common factors were positively associated with physical health (high financial level, being professionally active, normal BMI, good health status, alcohol consumption, higher values (> 22) of internal locus of control); or inversely associated (neurological and sleep problems, over two medical consultations/year). In BCSs, treatment by mastectomy or radiation therapy/brachytherapy, a short-time since diagnosis, current cancer therapy, and presence of sequalae were inversely associated with physical health. BCSs' health satisfaction was diminished with lower values of coping by positive thinking (≤ 14) and seeking social support (≤ 18).

CONCLUSIONS

HRQoL can be improved by developing strategies that increase internal locus of control and coping (positive thinking, problem-solving and seeking social support), and through health literacy.

Socioeconomic Factors Predict Long-Term Quality of Life of Cancer Survivors: An International Survey

INTRODUCTION

Despite advances in cancer treatment, the quality of life (QOL) of survivors varies significantly. We assessed the correlation between socioeconomic factors and long-term QOL in a global cohort of cancer survivors.

MATERIALS AND METHODS

Patients were offered surveys via online support groups. Using the Short Form-12 validated questionnaire, physical QOL (PQOL) and mental QOL (MQOL) well-being were compared to the general population. Socioeconomic factors were assessed with regression analysis for impact on QOL.

RESULTS

Seven hundred eighty two survivors from six continents responded. They were 57 ± 13 y and 68% female, 90.8% White, with 43 distinct cancer diagnoses. All survivors had PQOL and MQOL scores lower than the general population. Lower education level, household income, and non-White race all correlated with reduced PQOL and/or MQOL. Age was negatively correlated with PQOL (r = -0.08, P = 0.03) and positively correlated with MQOL (r = 0.142, P < 0.001). Care at large regional/academic centers was associated with higher MQOL (42 ± 14 versus 38 ± 11, P = 0.005). Age (β = -0.1, P = 0.04), education (β = 1.1, P = 0.005), and income (β = 2.0, P < 0.001) were predictors of PQOL, while age (β = 0.2, P < 0.001), income (β = 1.7, P = 0.002), and community hospital care (β = -3.6, P = 0.013) were predictors of MQOL.

CONCLUSIONS

In a large international survey of cancer survivors, we identified socioeconomic factors and their associations with QOL. Further work should be directed to provide durable support across all socioeconomic classes.

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.

Effects of social support and self-efficacy on eHealth literacy in Korean women undergoing breast cancer treatment: A secondary analysis

Objective

Patients with breast cancer need to seek out and understand relevant health information to make informed decisions about long-term and complicated illnesses. With the increased use of interventions using online health information, research on eHealth literacy should be expanded. However, existing studies on the factors affecting eHealth literacy in patients with breast cancer are currently lacking. This study, therefore, conducts a secondary analysis of a previous study that surveyed the quality of life of patients with breast cancer. The primary study found a significant correlation between eHealth literacy, social support, and self-efficacy. In this secondary analysis study, we specifically examine eHealth literacy among patients with breast cancer undergoing treatment, and how patient demographic characteristics, breast cancer-specific self-efficacy, and social support contribute to their eHealth literacy.

Methods

A total of 143 women receiving outpatient treatment or were hospitalized for breast cancer at a cancer hospital in South Korea participated in the study from January to November 2022. The eHealth Literacy Scale (eHEALS), Multidimensional Social Support Scale, and Breast Cancer Survivors Scale were utilized in the analysis. The data were analyzed using a multiple regression analysis.

Results

Full-time employment (β ​= ​0.19, P ​= ​0.006), a monthly family income of over 4 million won (3600 USD) (β ​= ​0.14, P ​= ​0.042), completing a high school education (β ​= ​0.52, P ​< ​0.001), completing college level or higher education (β ​= ​0.54, P ​< ​0.001), age (β ​= ​-0.23, P ​= ​0.003), and social support (β ​= ​0.21, P ​= ​0.002) were predictors of eHealth literacy, explaining 40.2% of the total variance (F ​= ​14.63, P ​< ​0.001).

Conclusions

Social support was identified as a new factor influencing eHealth literacy among patients with breast cancer undergoing treatment. Therefore, nursing interventions to strengthen social support should be developed to improve eHealth literacy.

The effect of health literacy, self-efficacy, social support and fear of disease progression on the health-related quality of life of patients with cancer in China: a structural equation model

BACKGROUND

Health literacy (HL), self-efficacy (SE), social support (SS) and fear of disease progression (FOP) are all important factors affecting health-related quality of life (HRQoL) in cancer patients. However, their synergistic effects and underlying mechanisms on HRQoL in cancer patients remain unclear. Therefore, the purpose of this study was to construct a structural equation model (SEM) to explore the underlying mechanism of factors affecting HRQoL. It is hoped that this study will provide a theoretical basis for future interventions.

METHODS

A cross-sectional design and convenience sampling method were used to investigate cancer inpatients in two general hospitals in Chongqing and Chengdu. Data were collected using structured scales, including HL, SE, SS, FOP and HRQoL. Finally, the SEM was constructed, and P ≤ 0.05 was considered significant.

RESULTS

There were 1749 participants included in this study. Correlation analysis showed that all variables were significantly correlated with one another except for symptoms, physical health (PD) and social family (SF) (p < 0.01). The SEM of the HRQoL had a good overall fit (GFI = 0.943, AGFI = 0.917, NFI = 0.950, RFI = 0.936, CFI = 0.955, IFI = 0.955, RMSEA = 0.072). The model indicated that HL had the strongest correlation with HRQoL (β = 0.398, p < 0.01), followed by FOP (β = -0.364, p < 0.01), SE (β = 0.347, p < 0.01) and SS (β = 0.184, p < 0.01).

CONCLUSIONS

The HRQoL of cancer patients is correlated with HL, SS, SE and FOP. HL can directly affect HRQoL and mediate HRQoL through SS and SE. Future programs should consider HL promotion, SE improvement and SS expansion as the breakthrough point when designing targeted intervention strategies. At the same time, the importance of the impact of FOP on the HRQoL of patients with cancer should not be ignored.

Development and Validation of a Food and Nutrition Literacy Questionnaire for Chinese Adults

The purpose of this study aimed to develop and validate the Food and Nutrition Literacy Questionnaire for Chinese adults (FNLQ). The dimensions and core components of Food and Nutrition Literacy were constructed though literature review and qualitative consensus study. A cross-sectional survey of 8510 participants was conducted. The reliability of the questionnaire was determined by internal consistency, the construct validity was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and the content validity was assessed by the Pearson correlation coefficient. From the literature review and qualitative methods, 20 core components and 50 questions of the FNLQ were developed, including 1 dimension of knowledge and 3 practice dimensions (ability of selection, preparing food and eating). The overall FNLQ questionnaire had good reliability and validity (Cronbach’s α = 0.893, χ2/DF = 4.750, RMSEA = 0.048, GFI = 0.891 and AGFI = 0.876). The average FNLQ score of all participants was (64.08 ± 12.77), and the score for the knowledge and understanding dimension was higher than that for the practice dimensions. In addition, 80 was set as the nutritional literacy threshold, and only 12.2% met this threshold in this survey. Sociodemographic and health status characteristics were predictors of FNLQ (R2 = 0.287, F = 244.132, p < 0.01). In conclusion, the FNLQ built in this study had good validity and reliability. It could be considered as a reliable tool to assess Food and Nutrition Literacy of Chinese adults.

The role of health literacy in cancer care: A mixed studies systematic review

BACKGROUND

Patients diagnosed with cancer face many challenges and need a good understanding of their diagnosis and proposed treatments to make informed decisions about their care. Health literacy plays an important role in this and low health literacy has been associated with poorer outcomes. The aims of this review are to identify which outcomes relate to health literacy in patients with cancer, and to combine this through a mixed studies approach with the patient experience as described through qualitative studies.

METHODS

Four electronic databases were searched in January 2021 to identify records relating to health literacy and patients with cancer. Records were independently screened then assessed for inclusion by two reviewers according to the following criteria: patients aged ≥18 years with cancer, English language publication AND health literacy measured with validated tool and measured outcome associated with health literacy OR qualitative study exploring the role of health literacy as patients make decisions about health. Quality was independently assessed by two reviewers. A narrative synthesis was performed, and findings integrated through concept mapping. This systematic review was registered with PROSPERO, entry CRD42020166454.

RESULTS

4441 records were retrieved. Following de-duplication, 2496 titles and abstracts were screened and full texts of 405 papers were reviewed for eligibility. 66 papers relating to 60 studies met the eligibility criteria. Lower health literacy was associated with greater difficulties understanding and processing cancer related information, poorer quality of life and poorer experience of care. Personal and situational influences contributed to how participants processed information and reached decisions about their care.

CONCLUSION

This review highlights the important role of health literacy for patients with cancer. Outcomes are poorer for those who experience difficulties with health literacy. Further efforts should be made to facilitate understanding, develop health literacy and support patients to become more involved in their care.

Mental health literacy and quality of life in Iran: a cross-sectional study

BACKGROUND

Mental health is one of the effective factors in the quality of life of people. The aim of the present study was to determine the status of mental health literacy (MHL) and its relationship with the quality of life across the Iranian general population.

METHODS

In this cross-sectional study, a multi-stage sampling method was used to survey 1070 participants from the city of Gonabad (Iran). The data collection tools were demographics section, mental health literacy scale (MHLS), and quality of life (SF-12) questionnaires. The data was analyzed by SPSS software version 24 using Independent sample t- test, One- way ANOVA, Pearson correlation, and logistic regression.

RESULTS

The mean and standard deviation of the total scores of MHL and quality of life were 113.54 (10.34) and 35.26 (6.42), respectively. The results revealed that there was a significant positive correlation between MHL and the quality of life (p < 0.001). In this study, there was a significant relationship between variables of sex, level of education, plus received information about mental illness and MHL (p < 0.001). The quality of life was higher in participants whose family members did not have a mental illness, had a high-income level, and received information about mental illness (p < 0.001). Logistic regression indicated that there was a significant relationship between the ability to recognize mental disorders plus knowledge of where to seek information and obtaining information related to mental health (p < 0.001).

CONCLUSION

Based on the results of this study, there was a correlation between health literacy and quality of life, and more attention should be paid to MHL. Thus, appropriate programs should be designed and implemented to enhance the level of MHL.

The effect of health literacy on health status among residents in Qingdao, China: a path analysis

BACKGROUND

Health literacy is a public health goal which can be used as an independent factor of health outcomes. This study aimed to assess the association between health literacy and health status, as well as the two mediating factors of behavior and self-efficacy among residents aged 15-69 years in Qingdao.

METHODS

A cross-sectional survey was implemented among residents aged 15-69 years (N = 3793) in Qingdao, China. A combination of stratified cluster random and proportional probability sampling methods was used to select subjects for this study. Data were collected using "The Chinese Citizen Health Literacy Questionnaire (2019)". We proposed a hypothetical model for the relationship between sociodemographic characteristics, health literacy, self-efficacy, health behavior, and health status, and used path analysis to validate the hypothesis.

RESULTS

The path analysis showed that higher education (β = 0.293) and income (β = 0.135) are positively and directly associated with greater health literacy, which was positively associated with health status (β = 0.057). Health literacy is a direct influencing factor of health behavior (β = 0.070) and self-efficacy (β = 0.099). Health behavior (β = 0.041) and self-efficacy (β = 0.173) exerted a positive direct effect on health status. The model explained 14.1% of variance for health literacy, 3.8% for self-efficacy, 5.7% for health behavior, and 15.0% for health status.

CONCLUSIONS

Health literacy was identified to be a critical factor in health status. The results emphasized that the dissemination of health knowledge, development of healthy behavior, and cultivation of self-efficacy should be jointly promoted to reinforce the level of health status among residents in future work.

Awareness of diagnosis, treatment and risk of late effects in Chinese survivors of childhood cancer in Hong Kong

BACKGROUND

For survivors of childhood cancer, awareness of personal health risks is a critical component of long-term health management.

OBJECTIVE

To evaluate the awareness of the diagnosis, treatment and risk of late effects among survivors of childhood cancer in Hong Kong.

METHODS

Between June 2019 and March 2020, this cross-sectional study recruited 155 adult survivors (mean age = 26.9, standard deviation [SD] = 6.4 years) and 45 parents of paediatric survivors (mean age = 11.1, SD = 3.6 years) from a long-term follow-up clinic. At >10 years post-treatment (mean = 13.4, SD = 7.6 years), they completed a structured questionnaire to report their cancer-specific knowledge. Multiple linear regression analysis was conducted to identify clinical, socioeconomic and behavioural factors associated with poor awareness.

RESULTS

The majority of participants accurately recalled their diagnoses (73.5%) and major treatment modalities (chemotherapy 92.4%, radiation 82.9% and surgery 88.2%). However, less than half (45%) of the participants recognized more than 25% of the total late effects for which they were at risk. The highest levels of awareness were reported for endocrine problems (49%), neurocognitive impairment (44%) and secondary cancers (43%), and the lowest for peripheral neuropathy (21%) and vision problems (23%). Compared with survivors of haematological malignancies, those of central nervous system (CNS) tumours (standardized estimate [B] = -9.33, 95% confidence interval [95% CI]: -13.41 to -5.26) and non-CNS solid tumours (B = -8.47, 95% CI: -12.39 to -4.94) had less knowledge about their diagnosis. Retaining medical records (P < .0001) and better medical information-seeking habits (P = .048) were associated with better awareness.

CONCLUSIONS

Survivors of childhood cancer in Hong Kong have deficient awareness of their personal health risks. They may benefit from the provision of a survivorship care plan and personalized education regarding treatment-related late effects.

Patients contributed in designing the study tools. Results were presented at a non-governmental organization.

Association of health literacy and medication adherence with health-related quality of life (HRQoL) in patients with ischemic heart disease

BACKGROUND

Medication Adherence (MA) and Health Related Quality of Life (HRQoL) are two inter-connected concepts, co-influenced by Health Literacy (HL), with significant impact on patient management and care. Thus, we aimed to estimate the association of HL and MA with HRQoL in IHD patients.

METHODS

Cross-sectional study of 251 IHD patients recruited from Lahore over 6 months period. HL, MA and HRQoL was assessed using validated questionnaires; 16-items of HL, Morisky Green Levine Scale (MGLS) and SF-12, respectively. Chi-square for significance, logistic-regression for association and linear regression for predictions were used.

RESULTS

IHD patients; males (p = 0.0001), having secondary-higher education (p = 0.0001), middle/upper class (p = 0.0001) and employed (p = 0.005) had adequate HL, and were more likely to be adherent (OR; 4.3, p = 0.014). Both physical (PCS-12) and mental (MCS-12) component scores of HRQoL for age, gender, education, area of residence, employment and MA were significantly higher in patients with adequate HL. In multinomial regression, improved PCS-12 scores tend to be higher in subjects having secondary-higher education (OR; 3.5, p = 0.067), employed (OR; 6.1, p = 0.002) and adherent (OR; 2.95, p = 0.218), while MCS-12 scores tend to be higher in patients < 65 years (OR; 2.2, p = 0.032), employed (OR; 3, p = 0.002) and adherent (OR; 4, p = 0.004). In adjusted model, HL (β;0.383, p = 0.0001) and MA (β; - 0.133, p = 0.018) were significantly associated with PCS-12, and MCS-12 with MA (β; - 0.161, p = 0.009) only.

CONCLUSION

Data suggested that adequate HL was significantly associated with adherence and both physical and mental dimensions of HRQoL were higher in IHD patients with adequate HL. Besides, HL and MA are independent predictors of HRQoL in IHD patients.

The Association Between Health Literacy and Self-rated Health Among Residents of China Aged 15-69 Years

INTRODUCTION

Health literacy is a critical determinant of health. However, the association between health literacy and outcomes among Chinese residents has not been studied using nationally representative data. This study examines the association between health literacy and self-rated health among Chinese residents based on the 2017 China Health Literacy Survey.

METHODS

The 2017 China Health Literacy Survey was conducted among non-institutionalized residents aged 15-69 years from 31 provinces in China. Self-rated health was measured using a single question with a 1-5 scale. Health literacy was assessed using the Chinese Health Literacy Scale. Multilevel linear regression models examined the association between health literacy and self-rated health. Data were collected in 2017 and analyzed between 2018 and 2019.

RESULTS

The final sample size was 85,384. The overall weighted mean of the self-rated health score was 4.02 (95% CI=4.00, 4.03). After adjusting for individual-, county-, and province-level covariates, Chinese residents with higher levels of health literacy were more likely to have better self-rated health (β=0.0007, SE=0.0002, p<0.001). Of 6 dimensions of health literacy, 4 (i.e., infectious diseases literacy, chronic diseases literacy, medical care literacy, and health information literacy) were associated with self-rated health. Additionally, self-rated health was associated with gender, age, education, occupation, annual household income, and chronic conditions.

CONCLUSIONS

Using nationally representative data collected in 2017, this study found that self-rated health is associated with health literacy among Chinese residents aged 15-69 years. The promotion of health literacy should be an important component of health education, patient management, and health promotion.

Quality of life and associated factors among adults living with cancer and their family caregivers

This study examined the association of needs, health literacy, and quality of life among adult Nigerians with cancer and family caregivers. A descriptive study was conducted involving 240 adults with cancer and family caregivers attending a tertiary hospital. More than two-thirds of participants reported moderate or high needs. Information (90.8%) and spiritual support (85%) were the domains of highest need among adults with cancer. Family/social support (85%) and spiritual support (81.7%) ranked the highest among family caregivers. A negative correlation was found between needs and quality of life. Stepwise regression analysis showed that needs and literacy explained 36% of the variance in adults with cancer's quality of life and 28% of the variance in family caregivers' quality of life. Spiritual need accounted l for 9.5% and 9.1% of variation for adults with cancer and family caregivers, respectively. Findings suggest that interventions with a focus on social/family and spiritual needs may improve wellbeing of adults with cancer and caregivers in Nigeria. This research are generalizable to other low-income countries where family values and spirituality are often a strong feature of daily life.
