Health literacy, illness perception, depression, and self-management among African Americans with type 2 diabetes

Health literacy and medication adherence in adults from ethnic minority backgrounds with Type 2 Diabetes Mellitus: a systematic review

BACKGROUND

For people living with Type 2 Diabetes Mellitus (T2DM), achieving optimal health outcomes requires optimal self-management and adherence to medical treatment. While some studies suggest an association between poor medication adherence and lower levels of health literacy, the evidence for this association remains inconclusive. This systematic review aimed to synthesise the evidence on the association between health literacy and medication adherence among adults from ethnic minority backgrounds living with T2DM.

METHODS

Medline (Ovid), The Cochrane Library, Embase (Ovid), PsycInfo (EBSCO), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCO) were searched systematically for peer-reviewed literature, published until January 2024. Studies were included in this review if they assessed health literacy and medication adherence among ethnic minority people with T2DM. Two reviewers independently screened and selected the studies, extracted data from the included articles, and assessed the methodological quality of the studies. The methodological quality and bias in designing, conducting, and analysis of each study were evaluated using a standardised JBI critical appraisal tool.

RESULTS

Of the total 6,318 identified studies, seven studies were included in the review. The total participant sample sizes across these studies varied from 53 to 408 participants. All included studies incorporated cross-sectional design for the research, with the majority conducted in the USA. Of the seven unique studies, only one study observed a significant association between health literacy and medication adherence among people from an ethnic minority background.

CONCLUSIONS

Evidence on the association between health literacy and medication adherence in ethnic minority adults with T2DM is weak and inconsistent. To understand this association more clearly in ethnic minority populations and to address the disparities in cultural and linguistic considerations, well-designed studies are required.

Autophagy modulators in type 2 diabetes: A new perspective

Type 2 diabetes (T2D) is a chronic metabolic disorder caused by defective insulin signaling, insulin resistance, and impairment of insulin secretion. Autophagy is a conserved lysosomal-dependent catabolic cellular pathway involved in the pathogenesis of T2D and its complications. Basal autophagy regulates pancreatic β-cell function by enhancing insulin release and peripheral insulin sensitivity. Therefore, defective autophagy is associated with impairment of pancreatic β-cell function and the development of insulin rersistance (IR). However, over-activated autophagy increases apoptosis of pancreatic β-cells leading to pancreatic β-cell dysfunction. Hence, autophagy plays a double-edged sword role in T2D. Therefore, the use of autophagy modulators including inhibitors and activators may affect the pathogenesis of T2D. Hence, this review aims to clarify the potential role of autophagy inhibitors and activators in T2D.

Do Health Literate Older People Have Fewer Depressive Symptoms? Evidence from the Urban Areas of Western China

BACKGROUND

Previous research has indicated that health literacy has a good influence on the mental health among older adults. The current study aims to determine whether health literacy is linked to depressive symptoms in older adults in west China, and tries to detect the mechanisms underlying the linkage between health literacy and depressive symptoms in the Chinese context.

METHODS

Study data were obtained from a cross-sectional ageing health literacy survey conducted in 2017 in Western China, and 812 urban individuals aged 60 and older were selected.

RESULTS

Health literacy was associated with fewer symptoms of depression; additionally, older adults who reported harmonious family and filial piety, those with greater self-rated health, and those with a higher level of life satisfaction tended to have fewer depressive symptoms, whereas older individuals who reported a poor financial status and those with functional impairment had more depressive symptoms.

CONCLUSIONS

The findings indicate the protective role of health literacy against depressive symptoms among urban older adults. In addition, the findings also indicate the potential impact of financial strain and functional impairment on the development of depressive symptoms and show that other factors including a harmonious family, filial piety, self-rated health and life satisfaction are generally protective against depressive symptoms. Specific evidence is presented for the national action plans and public health strategies needed to reinforce and promote health literacy in the Chinese context. The current results also suggest that health education and promotion programs designed to strengthen financial assistance, functional improvement, family relationships, life satisfaction and self-rated health should gain a growing importance on the health agenda. Future longitudinal studies, mediation or moderator models, and structural equation modeling would be needed to identify a causal relationship, the moderating or mediating effect, and the possible pathways underlying the linkage between health literacy and depressive symptoms, respectively.

Participant and group facilitator perspectives on a novel culturally tailored diabetes self-management program for African Americans

BACKGROUND

African Americans with type 2 diabetes experience disparities in their care and diabetes health-related outcomes. Diabetes self-management programs such as Healthy Living with Diabetes (HLWD) are important but do not account for the unique cultural experiences of African Americans. Also, a culturally tailored program focused on addressing sociocultural beliefs and providing race-congruent peer support, Peers LEAD (Peers Supporting Health Literacy, Self-Efficacy, Self-Advocacy, and Adherence) was implemented in two midwestern cities to improve medication adherence but does not include diabetes self-management topics included in HLWD. In an attempt to fill the gaps from both HLWD and Peers LEAD, Peers EXCEL (Peers' Experience in Communicating and Engaging in Healthy Living) was designed to integrate both programs.

METHODS

Our study explored the perceptions of African American participants and facilitators of the separate HLWD and Peers LEAD programs, on the proposed new Peers EXCEL program using focus groups and interviews. Findings were analyzed by research assistants trained in qualitative research using deductive and inductive open coding approaches.

RESULTS

Participants appreciated the cultural fit of Peers EXCEL for African American communities which is a feature that was lacking in HLWD. They shared the need to include topics such as the relationships between systemic racism and diabetes.

CONCLUSION

Participants' feedback of Peers EXCEL reveals the importance of including various community members' perspectives in the design of new diabetes self-management programs tailored for African Americans.

Relationship between illness perception and self-management behaviors among women with gestational diabetes mellitus in China during the COVID-19 pandemic: A mediating role of depression

OBJECTIVE

Describe the current status of illness perception, depression, and self-management behaviors among women with gestational diabetes mellitus (GDM) during the COVID-19 pandemic, and explore the role of depression in the relationship between illness perception and self-management behaviors among women with GDM.

METHODS

Pregnant women diagnosed with GDM were recruited at the obstetrics clinic of a Grade-A tertiary hospital in Wuhan, through convenience sampling. Self-reported questionnaires including basic information, illness perception, depression, and self-management behaviors were used to collect data from April 2021 to February 2022. Mediation analysis was performed by SPSS Process macro.

RESULTS

Among GDM pregnant women, the mean self-management behaviors score was 73.89 (SD = 12.21), the mean illness perception score was 31.80 (SD = 8.77), and 44.3% had depression scores of 10 or higher. The indirect effect of illness perception on self-management behaviors mediated by depression was significant (path a * b, β = -0.045), accounting for 26.6% of the total effect.

CONCLUSION

GDM pregnant women have a certain negative illness perception of GDM, and the detection rate of depression symptoms is relatively high. The level of self-management behaviors among GDM pregnant women is notably suboptimal and warrants improvement. Depression partially mediates the relationship between illness perception and self-management behaviors. Improving positive illness perception and decreasing depression are important strategies to improve self-management behaviors in women with GDM.

Effects of Illness Perception and Coping Style on Self-Management in Peritoneal Dialysis Patients: A Cross-Sectional Study

Aim

Chronic disease self-management is critical to disease prognosis and patient quality of life. Several psychological factors influence this process of self-management. In this background, the present study investigated the impact of illness perceptions and coping style on self-management in people with peritoneal dialysis (PD).

Methods

The study is a cross-sectional study. From May 2022 to January 2023, a convenience sampling method was used to recruit 246 peritoneal dialysis patients. General information questionnaire, brief illness perception questionnaire, medical coping style modes questionnaire and the self-management scale for peritoneal dialysis patients were used in this study. We used SPSS 24.0 to analyze the data, and the statistical methods included descriptive analysis, single factor analysis, Pearson correlation analysis and multiple linear regression analysis.

Results

A total of 246 patients were included in this study (93.89% response rate). Cognitive representations and emotional representations were 30.40, 14.18, respectively. However, illness comprehensibility was 2.87. Illness perceptions were negative significantly correlated with self-management. With regard to coping style, our patients were more likely to adopt avoidance and resignation coping style. Confrontation and avoidance were positively related to self-management, while acceptance-resignation was negatively related.

Conclusion

Self-management of peritoneal dialysis patients needs to be improved. Age, female sex, monthly income, illness perceptions and coping style were independently associated with self-management.

Impact

These findings suggest that interventions that improve illness perceptions and coping style should be explored to ultimately improve their self-management. For example, patients can be provided with psychological counseling so that they can face the disease correctly, and we should pay attention to the positive role of social support.

The relationship between health literacy and blood sugar control in rural areas among diabetes patients

Background

Although the relationship between health literacy and glycemic control has been explored in patients with diabetes, little is known about the relationship between different categories of diabetes health literacy and glycemic control in rural areas. Therefore, this study focused on the relationship between different categories of health literacy and glycemic control among diabetic patients in rural areas of Guangxi, China.

Objective

To explore the potential profiles of health literacy among rural diabetes patients in Guangxi and investigate their relationship with blood sugar control.

Methods

A health literacy questionnaire was administered to 2280 rural diabetes patients in five cities in the Guangxi Zhuang Autonomous Region. Latent profile analysis was conducted to identify potential health literacy profiles.

Results

Health literacy among rural diabetes patients in Guangxi could be categorized into high literacy-high functionality and low literacy-low criticality groups. The latent categories of health literacy were associated with blood sugar control, with diabetes patients in the high literacy-high functionality group demonstrating better blood sugar control than those in the low literacy-low criticality group (P < 0.05).

Conclusion

Health literacy among rural diabetes patients in Guangxi exhibits heterogeneity. Healthcare professionals should pay attention to patients with low literacy and low criticality in rural areas and develop interventions to enhance their health literacy, thereby improving their blood sugar control.

Health literacy and self-management among middle-aged and young hypertensive patients: a parallel mediation effect of illness perception and self-efficacy

Background

Hypertension is increasingly prevalent among young and middle-aged populations in rural China, accompanied by suboptimal self-management. Given that this population forms the backbone of the labor force, enhancing their self-management capabilities is crucial for improving overall population health. Studies indicate that individuals with good health literacy are more likely to effectively manage their health.

Methods

Grounded in the health literacy skills framework, a model was constructed in this study to examine the impact of health literacy on self-management among young and middle-aged hypertensive patients in rural China. Meanwhile, the mediating roles of illness perception and self-efficacy were also verified. Using a multi-stage stratified random sampling method, 338 patients were recruited to participate in the study. Structural equation modeling was utilized to establish the relationship model, and bootstrap tests were carried out to examine the mediating effects.

Results

The average self-management score was 70.45 ± 11.36. Health literacy exhibited a positive correlation with self-management (standardized β = 0.372, p < 0.001). The mediating effects through illness perception and self-efficacy were 0.040 and 0.236, constituting 6.68 and 39.31% of the total effect, respectively.

Conclusion

Illness perception and self-efficacy serve as parallel mediators amid the association between health literacy and self-management. Implementing psychological counseling and health education is imperative for augmenting self-management competence and cultivating an adaptive coping mentality.

Racial Disparities in Selected Complications and Comorbidities among People with Type 2 Diabetes

Type 2 diabetes (T2D) is a growing public health concern, disproportionately impacting racial and ethnic minorities. Assessing disparities is the first step towards achieving the translation goal to reduce disparities in diabetes outcomes, according to the Centers for Disease Control and Prevention (CDC)'s Division of Diabetes. We analyzed the data of patients (18+ years) diagnosed with T2D between 1 January 2012 and 31 March 2017, using the electronic health records of the University of Texas Medical Branch at Galveston. We compared the crude rate and age-standardized rate (using direct method) of selected micro- and macrovascular complication rates, associated obesity, and insulin dependence among racial and ethnic groups. Our sample included 20,680 patients who made 394,106 visits (9922 non-Hispanic White patients, 4698 non-Hispanic Black patients, and 6060 Hispanic patients). Our results suggest a higher risk of acquiring macrovascular (hypertension, ischemic disease, and stroke) and microvascular (renal, ophthalmic, and neurological) complications in Black patients compared to non-Hispanic White and Hispanic patients. The rates of stage I or II obesity were higher in Black patients compared with White and Hispanic patients. The rates of insulin use rather than oral hypoglycemics were also higher in Black patients than White and Hispanic patients. The disparities in terms of the higher susceptibility to complications among Black patients are possibly linked to the socioeconomic disadvantages of this population, leading to poorer management. Prevention strategies are warranted to reduce the incidence of T2D complications in racial minorities.

A cross-sectional study on social determinants of mental health during COVID-19 among adults in California

AIM

To explore the impact of structural and intermediary social determinants of health (SDoH) on Californian adults' mental health during the early phase of the COVID-19 pandemic.

DESIGN

This cross-sectional study used data from the 2020 cycle of the California Health Interview Survey, the largest US state-level population health survey.

METHODS

Descriptive statistics and logistic regression were used to analyse the data. Using a general social determinant of health framework, we operationalized different survey questions to measure structural and intermediary determinants of mental health.

RESULTS

Mental health during the early phase of COVID-19 among adults in California was associated with age, gender, health conditions, delayed care, employment status (loss of job or reduced income) and discrimination. People in higher social strata were more likely to have better mental health for many of these factors.

CONCLUSION

This study supports the assertion that material circumstances (such as employment status) and discrimination are associated with experiencing mental health issues among adults in California during COVID-19. Racism is a public health issue, and as nurses, addressing racism is critical. In addition, much work is needed to address SDoH to improve health outcomes, especially among marginalized populations.

IMPACT

This study addressed the knowledge gap concerning the social determinants of mental health among Californian adults during the early phase of the COVID-19 pandemic. Those who had reduced income and those who lost their jobs during the COVID-19 pandemic were 46% and 56%, respectively, more likely to report mental health problems. Those who experienced discrimination in healthcare were 304% more likely to report mental health issues. This research will increase the understanding of the social determinants of health, particularly for those with chronic illnesses and mental health issues during the COVID-19 pandemic.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution, as we used an existing US state dataset. However, California Health Interview Survey is the largest state health survey in the United States and interviews more than 20,000 households each year representing the health care needs of Californians.

Medication Adherence and Its Associated Factors among Patients with Type 2 Diabetes Mellitus Attending Primary Health Centers of Eastern Province, Saudi Arabia

Medication adherence by patients with diabetes is critical, as it plays a crucial role in individuals' long-term health and well-being. We evaluated the medication adherence, illness perception, diabetes knowledge, and associated factors among patients with type 2 diabetes mellitus (T2DM) attending primary health centers (PHCs) in the eastern province of the Kingdom of Saudi Arabia (KSA) using a validated Arabic version of a data collection form. In order to identify the variables that are associated with medication adherence, we applied a logistic regression analysis. Furthermore, we performed the Spearman test to find the correlation between medication adherence, illness perception, and diabetes knowledge. Of the 390 studied patients, 21.5% had low medication adherence, and it was significantly associated with gender (adjusted OR (AOR) = 1.89, 95% CI = 1.27-2.73, p = 0.003) and duration of diabetes (AOR = 0.83, 95% CI = 0.67-0.95, p = 0.017). Furthermore, we found a significant positive correlation between medication adherence and illness perception (rho = 0.217, p = 0.007) and knowledge of diabetes and medication adherence (rho = 0.425, p < 0.001). We recommend improving T2DM patients' knowledge about the importance of adherence to their medication regimen in several health education sessions at the PHCs. In addition, we recommend mixed-method medication adherence assessment surveys in different parts of the KSA.
