The association between self-care and quality of life in hypertensive patients: findings from the Azar cohort study in the North West of Iran

Health effects of shrinking hyper-saline lakes: spatiotemporal modeling of the Lake Urmia drought on the local population, case study of the Shabestar County

Climate change and its respective environmental impacts, such as dying lakes, is widely acknowledged. Studies on the impact of shrinking hyper-saline lakes suggest severe negative consequences for the health of the affected population. The primary aim was to investigate the relationship between changes in the water level of the hyper-saline Lake Urmia, along with the associated salt release, and the prevalence of hypertension and the general state of health of the local population in Shabestar County north of the lake. Moreover, we sought to map the vulnerability of the local population to the health risks associated with salt-dust scatter using multiple environmental and demographic characteristics. We applied a spatiotemporal analysis of the environmental parameters of Lake Urmia and the health of the local population. We analyzed health survey data from local health care centers and a national STEPS study in Shabestar County, Iran. We used a time-series of remote sensing images to monitor the trend of occurrence and extent of salt-dust storms between 2012 and 2020. To evaluate the impacts of lake drought on the health of the residences, we investigated the spatiotemporal correlation of the lake drought and the state of health of local residents. We applied a GIScience multiple decision analysis to identify areas affected by salt-dust particles and related these to the health status of the residents. According to our results, the lake drought has significantly contributed to the increasing cases of hypertension in local patients. The number of hypertensive patients has increased from 2.09% in 2012 to 19.5% in 2019 before decreasing slightly to 16.05% in 2020. Detailed results showed that adults, and particularly females, were affected most by the effects of the salt-dust scatter in the residential areas close to the lake. The results of this study provide critical insights into the environmental impacts of the Lake Urmia drought on the human health of the residents. Based on the results we suggest that detailed socioeconomic studies might be required for a comprehensive analysis of the human health issues in this area. Nonetheless, the proposed methods can be applied to monitor the environmental impacts of climate change on human health.

Knowledge and Behaviors Toward Health Care for Elderly Patients with Hypertension, and Quality of Life Among Informal Caregivers in Northern Thailand

BACKGROUND

Informal caregivers play an important role in caring for patients with chronic conditions. Little is known about the quality of life among caregivers of patients with chronic illnesses in Thailand. The purpose of this study was to investigate the relationships among knowledge and behaviors toward health care for elderly patients with hypertension, and the quality of life among informal caregivers.

METHODS

A total of 402 informal caregivers for their elderly co-habitants suffering from hypertension were randomly selected to participate in this cross-sectional study. Data collection was performed in rural areas of Phayao province, located in the northern part of Thailand. Self-administered questionnaires were employed, which covered knowledge and behaviors toward health care for elderly patients with hypertension, and the Thai version of the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) questionnaire.

RESULTS

The scores of knowledge and behaviors toward health care for elderly patients with hypertension, and the quality of life were at low and fair levels. In the multivariable linear regression model, the results showed that four variables - age, caregiver's relationship to the patient, knowledge, and behaviors toward health care for elderly patients with hypertension - were significantly related to quality of life among caregivers (p < 0.05).

CONCLUSION

Knowledge and behaviors toward health care for hypertensive patients influence the quality of life among informal caregivers. The caregivers in rural communities should be encouraged to become educated on the stages of hypertension, preparation for taking care of the elderly with high blood pressure, and effective behavioral care for patients, in order to improve the quality of life of both caregiver and patient. In addition, health care providers should have clear guidelines for development of the health care system to enhance the potential care and quality of life among informal caregivers.

Self-rated health and psychological health among hypertensive patients in Palestine

The study has investigated the self-rated psychological health of hypertensive patients in Palestine. To that end, a stratified random sample of 502 hypertensive patients (aged ⩾ 18 years) was asked to complete a validated Arabic version of the General Health Questionnaire (GHQ-28). After collection, the data were analyzed using descriptive statistics, Mann-Whitney U test and logistic regression. In this study, it was found the mean scores for GHQ were statistically higher for females than males (p < 0.05). The females were found to be 1.701 (95% CI = 1.025-2.823) times more at risk of psychological disorders compared to males. In conclusion, improvement of social determinants of hypertensive patients can make a difference in their psychological/mental health.

Relationship between self-management behaviors and health-related quality of life among Chinese patients with coronary heart disease: A cross-sectional study

Background: Coronary heart disease (CHD) has become one of the leading cause of death and physical disability in China. However, the relationship between self-management behaviors and health-related quality of life (HrQoL) among CHD patients in Chinese community settings is unclear.Aim: To explore the relationship between self-management behaviors and HrQoL among CHD patients in Chinese community settings.Methods: 220 participants were recruited from a community setting in Xi'an city, China. A cross-sectional study was conducted by using the Coronary Artery Disease Self-Management Scale (CSMS) and Chinese Mandarin version of the Short-Form 36 Health Survey (SF-36) on HrQoL.Results: Compared with Chinese norms, the CHD patients reported poorer HrQoL (P < 0.05). Pearson correlation analyses identified positive correlations (r = 0.117-0.328, P < 0.05) between self-management behaviors and HrQoL among the CHD patients in Chinese community settings.Conclusion: It is critical to improve self-management behaviors and HrQoL of CHD patients in Chinese communities.

Self-management and psychological resilience moderate the relationships between symptoms and health-related quality of life among patients with hypertension in China

PURPOSE

To examine whether and how self-management and psychological resilience could moderate the relationships between symptoms and health-related quality of life (HRQoL) among hypertensive patients in China.

METHODS

This was a cross-sectional study of 220 participants recruited from January to May, 2018. Demographic and clinical information were obtained from medical records and by patient interview. The Chinese version of 17-item Hypertension-specific Symptom Scale, 21-item Self-Management Scale, and 10-item Connor-Davidson Resilience Scale (CD-RISC-10) as well as Short Form 12 Health Survey (SF-12) were used to collect information in this research. The moderation effects of self-management and psychological resilience were explored using the PROCESS macro for SPSS.

RESULTS

Among all patients, 128 (58.2%) were female, 106 (48.2%) had a bachelor degree or higher, and 133 (60.5%) had moderate to severe Charlson Comorbidity Index. Both self-management and psychological resilience were negatively correlated to symptoms (r = - 0.259, p < 0.001; r = - 0.282, p < 0.001) but positively correlated to physical (r = 0.316, p < 0.001; r = 0.344, p < 0.001) and mental (r = 0.273, p < 0.001; r = 0.309, p < 0.001) HRQoL. After controlling for potential covariates, self-management could moderate the associations between symptoms and physical HRQoL (p = 0.041, ΔR² = 0.010), while psychological resilience could moderate the relationships between symptoms and mental HRQoL (p = 0.02, ΔR² = 0.010).

CONCLUSIONS

For hypertension patients, HRQoL is dependent on the severity of symptoms, engagement of self-management behaviors, and psychological resilience, which should be carefully considered when to improve patients' HRQoL by health care providers.
