Clinical effectiveness of stress-reduction techniques in patients with hypertension: systematic review and meta-analysis

Nonpharmacologic Management of Hypertension in Older Adults

Hypertension is ubiquitous among older adults and leads to major adverse cardiovascular events. Nonpharmacologic lifestyle interventions represent important preventive and adjunct strategies in the treatment of hypertension and have benefits beyond cardiovascular disease in this population characterized by a high prevalence of frailty and comorbid conditions. In this review, the authors examine nonpharmacologic interventions with the strongest evidence to prevent cardiovascular disease with an emphasis on the older adults.

A Need for Improvement in the Definition of Resistant Arterial Hypertension

With the medical and social importance of resistant arterial hypertension (HTN) in mind, we had three goals in this paper: to study the definitions of resistant HTN in the guidelines on the topic, to analyze them, and to suggest some improvements. We found (at least) eleven insufficiencies in the definition of resistant HTN: (1) different blood pressure (BP) values are used for diagnoses; (2) the number of BP measurements is not specified; (3) the time-frame for the definition is not obtained; (4) it fails to provide normal or target or controlled BP values; (5) secondary HTN is not currently defined as true resistant HTN, but as apparently treatment-resistant HTN; (6) the definition usually directly incorporates BP cut-offs for systolic BP (sBP) and diastolic BP (dBP) making the diagnosis temporary; (7) stress is not included in the exclusion strategy for resistant HTN; (8) there is potentially a need to introduce a category of recovered resistant HTN; (9) to what degree do healthy lifestyle measures have to be fulfilled to consider it as sufficient to change the diagnosis from "apparent treatment-resistant HTN" to the "resistant HTN"; (10) sBP values normal-for-the-age for 61 and 81 year old patients in some guidelines fulfill the criterion for resistant HTN; (11) it probably ought to read "In the absence of contraindications and compelling indications…" in the others. We believe that it is better to use the phrase "above the target BP" for the definition of (treatment) resistant HTN, because the whole story of resistant HTN is related to non-responders to antihypertensive treatment. Therefore, as we treat to target and not to normal values, it is appropriate to define resistant HTN as an insufficiency to reach the target BP values. Moreover, the definition of (treatment) resistant HTN should not be universal for every patient with HTN, but it should be age-related: (treatment) resistant HTN is elevated BP over the target/normal BP values. Using this modification, there will be no need to automatically change the definition of resistant HTN when we change the BP targets in the future.

The Black-White Disparity in Preterm Birth: Race or Racism?

Policy Points Racism is an upstream determinant of health that influences health through many midstream and downstream factors. This Perspective traces multiple plausible causal pathways from racism to preterm birth. Although the article focuses on the Black-White disparity in preterm birth, a key population health indicator, it has implications for many other health outcomes. It is erroneous to assume by default that underlying biological differences explain racial disparities in health. Appropriate science-based policies are needed to address racial disparities in health; this will require addressing racism.

Translation and Cross-cultural Adaptation of the Self-care of Hypertension Inventory for Thais With Hypertension

BACKGROUND

Self-care is essential for treating hypertension by lowering and controlling blood pressure, to ultimately reduce cardiovascular disease. A valid and reliable hypertension self-care measure is needed for the Thai population.

OBJECTIVE

The aim of this study was to translate a cross-cultural adaptation of the Self-care of Hypertension Inventory (SC-HI) into Thai and conduct a pretest of the Thai SC-HI (version 2.0).

METHODS

We performed a methodological study. The stepped approach included translation of the original version of the SC-HI into Thai (forward), synthesis of translation, translation of the Thai version back to English, expert committee review, and pretesting. Pretest phase for feasibility, interobserver agreement, and temporal stability tests were performed in 140 patients with hypertension.

RESULTS

Translation equivalence was obtained between the Thai and the original US versions. The item-level content validity index was rated by 9 experts; the relevance, clarity, simplicity, and ambiguity criteria were all 1.00. Similarly, the scale-level content validity indices were 1.00 for the overall instrument and the self-care maintenance, self-care management, and self-care confidence scales. The item-level intraclass correlation coefficients (ICCs) had a range of 0.97 to 1.00 for interobserver agreement and 0.95 to 1.00 for test-retest, respectively. The interobserver ICCs were 0.99 for the total scale and 3 separate scales. The test-retest ICCs were 0.99 for the total scale, with a range of 0.97 to 0.99 for the three separate scales.

CONCLUSION

The process of cross-cultural adaptation warranted validity and reliability testing of the Thai SC-HI. Psychometric testing of this instrument is needed for evaluation in a large sample of individuals with hypertension.

Efficacy of rational emotive behavior therapy for the improvement of knowledge and risk perception of hypertension among university lecturers in South East Nigeria: REBT for university lecturers' hypertension improvement

BACKGROUND

This study determined the effectiveness of a rational emotive behavioral therapy (REBT) intervention on knowledge of risks of hypertension among university lecturers in South-east geopolitical zone of Nigeria.

METHODS

The study used a group randomized controlled trial design to group the participants into treatment group and a waiting-list control group and the hypertension knowledge questionnaire and the Perceived Risks of Hypertension Questionnaire to collect a pretest, posttest, and follow-up data of this study. The sample of the study was 84 university lecturers in public universities in Southeast Nigeria (University of Nigeria, Nsukka, Enugu State, Nnamdi Azikiwe University, Awka, Anambra State) who satisfies the requirements to participate in the study. The study lasted for 10 weeks. The data collected for the study were analyzed using repeated measures ANOVA and t test statistics.

RESULTS

The findings of this study were that REBT health educational intervention effectively increased the education foundation and business education lecturers' knowledge and perceived risk of hypertension compared to participants in waitlist group. Lastly, the outcomes of the follow-up measures indicate that the increased knowledge and perceived risks of hypertension acquired during the training program was sustained by the treatment group one month after the end of program.

CONCLUSION

The REBT health educational intervention program could be utilized to increase knowledge and perceived risks of hypertension among university lecturers in public universities in Southeast Nigeria.

Weekly green space visit duration is positively associated with favorable health outcomes in people with hypertension: Evidence from Shenzhen, China

BACKGROUND

Studies from high income 'western' countries indicate that green space visit duration is associated with better health. However, scant comparable research has been done in developing countries with rapid urbanization and on the potential health impacts of specific green infrastructure.

OBJECTIVE

Associations between green space visit duration, green infrastructure and various health outcomes were assessed in hypertensive patients.

METHODS

A stratified multi-stage cluster random sampling method was applied to select 1116 patients with hypertension aged 35 years or older in Shenzhen, China. Face-to-face survey, physical examination and laboratory biochemical tests were applied to obtain information. Binary logistic regressions with restricted cubic splines were used to explore the degree of linearity in associations between green space visit duration and the following health outcomes: central obesity; diabetes; blood pressure; dyslipidemia; poor physical health; poor mental health. Models were adjusted for age, sex, education, marital status, occupation, and socioeconomic status. Further analysis was made for presence of the following health promoting green infrastructure: health knowledge promotion areas; walking trails; fitness areas; group exercise venues.

RESULTS

Each additional 30 min green space visitation was linearly associated with lower odds of self-reported poor mental health [OR (95%CI): 0.937 (0.891-0.985)], self-reported poor physical health [OR (95%CI): 0.918 (0.872-0.966)], and central obesity [OR (95%CI): 0.951 (0.907-0.997)]. Odds of poor mental health [OR (95%CI): 0.886 (0.788-0.997)], poor physical health [OR (95%CI): 0.882 (0.782-0.996)] and central obesity [OR (95%CI): 0.855 (0.765-0.955)] were founded to decrease with a greater number of health promoting green infrastructure.

CONCLUSION

More time spent in green space and with more types of green infrastructure were favourably associated with central obesity, and physical and mental health in people with hypertension.

Explaining the Black-White Disparity in Preterm Birth: A Consensus Statement From a Multi-Disciplinary Scientific Work Group Convened by the March of Dimes

In 2017-2019, the March of Dimes convened a workgroup with biomedical, clinical, and epidemiologic expertise to review knowledge of the causes of the persistent Black-White disparity in preterm birth (PTB). Multiple databases were searched to identify hypothesized causes examined in peer-reviewed literature, 33 hypothesized causes were reviewed for whether they plausibly affect PTB and either occur more/less frequently and/or have a larger/smaller effect size among Black women vs. White women. While definitive proof is lacking for most potential causes, most are biologically plausible. No single downstream or midstream factor explains the disparity or its social patterning, however, many likely play limited roles, e.g., while genetic factors likely contribute to PTB, they explain at most a small fraction of the disparity. Research links most hypothesized midstream causes, including socioeconomic factors and stress, with the disparity through their influence on the hypothesized downstream factors. Socioeconomic factors alone cannot explain the disparity's social patterning. Chronic stress could affect PTB through neuroendocrine and immune mechanisms leading to inflammation and immune dysfunction, stress could alter a woman's microbiota, immune response to infection, chronic disease risks, and behaviors, and trigger epigenetic changes influencing PTB risk. As an upstream factor, racism in multiple forms has repeatedly been linked with the plausible midstream/downstream factors, including socioeconomic disadvantage, stress, and toxic exposures. Racism is the only factor identified that directly or indirectly could explain the racial disparities in the plausible midstream/downstream causes and the observed social patterning. Historical and contemporary systemic racism can explain the racial disparities in socioeconomic opportunities that differentially expose African Americans to lifelong financial stress and associated health-harming conditions. Segregation places Black women in stressful surroundings and exposes them to environmental hazards. Race-based discriminatory treatment is a pervasive stressor for Black women of all socioeconomic levels, considering both incidents and the constant vigilance needed to prepare oneself for potential incidents. Racism is a highly plausible, major upstream contributor to the Black-White disparity in PTB through multiple pathways and biological mechanisms. While much is unknown, existing knowledge and core values (equity, justice) support addressing racism in efforts to eliminate the racial disparity in PTB.

Biofeedback therapeutic effects on blood pressure levels in hypertensive individuals: A systematic review and meta-analysis

INTRODUCTION

Systemic arterial hypertension (SAH) is considered a multifactorial disease characterized by a persistent increase in blood pressure levels. Currently, the efficient control of blood pressure is achieved by both the use of pharmacological therapy and the control of risk factors. In addition, the use of biofeedback (BFB) as a non-pharmacological strategy represents a promising therapy.

OBJECTIVE

This study aims to evaluate the effects of BFB on systolic and diastolic blood pressure levels, as well as on environmental and psychosocial factors in patients with essential SAH.

METHODS

A systematic review (SR) of the literature was carried out in English and Portuguese using the following databases: SCIELO, LILACS, CINAHL, Cochrane, and PubMed. The search strategy included a mix of terms for the key concepts Biofeedback, Heart Rate Variability, Psychophysiological Feedback, and Heart Biofeedback. Studies were analyzed independently.

RESULTS

The included studies evaluated a total of 462 subjects of both sexes. The meta-analysis revealed that BFB significantly elicited greater blood pressure control, mainly improving DBP levels (Z = 2.15; P = 0.03).

DISCUSSION

Besides improvement in DBP readings post-intervention, BFB also resulted in better disease-related environmental and psychosocial factors, such as reduced stress levels. The magnitude of effect did not appear to depend on the type of BFB applied.

CONCLUSION

This SR demonstrated that BFB with visual and/or auditory information is a complementary option to pharmacological treatment in the management of individuals with systolic and diastolic arterial hypertension. Moreover, the use of this adjuvant therapy seems to facilitate better DPB control.

Compared to Individuals with Mild to Moderate Obstructive Sleep Apnea (OSA), Individuals with Severe OSA Had Higher BMI and Respiratory-Disturbance Scores

Objective: Individuals with obstructive sleep apnea (OSA) are at increased risk to suffer from further somatic and sleep-related complaints. To assess OSA, demographic, anthropometric, and subjective/objective sleep parameters are taken into consideration, but often separately. Here, we entered demographic, anthropometric, subjective, and objective sleep- and breathing-related dimensions in one model. Methods: We reviewed the demographic, anthropometric, subjective and objective sleep- and breathing-related data, and polysomnographic records of 251 individuals with diagnosed OSA. OSA was considered as a continuous and as categorical variable (mild, moderate, and severe OSA). A series of correlational computations, X²-tests, F-tests, and a multiple regression model were performed to investigate which demographic, anthropometric, and subjective and objective sleep dimensions were associated with and predicted dimensions of OSA. Results: Higher apnea/hypopnea index (AHI) scores were associated with higher BMI, higher daytime sleepiness, a higher respiratory disturbance index, and higher snoring. Compared to individuals with mild to moderate OSA, individuals with severe OSA had a higher BMI, a higher respiratory disturbance index (RDI) and a higher snoring index, while subjective sleep quality and daytime sleepiness did not differ. Results from the multiple regression analysis showed that an objectively shorter sleep duration, more N2 sleep, and a higher RDI predicted AHI scores. Conclusion: The pattern of results suggests that blending demographic, anthropometric, and subjective/objective sleep- and breathing-related data enabled more effective discrimination of individuals at higher risk for OSA. The results are of practical and clinical importance: demographic, anthropometric, and breathing-related issues derived from self-rating scales provide a quick and reliable identification of individuals at risk of OSA; objective assessments provide further certainty and reliability.

Lifestyle interventions for the prevention and treatment of hypertension

Hypertension affects approximately one third of the world's adult population and is a major cause of premature death despite considerable advances in pharmacological treatments. Growing evidence supports the use of lifestyle interventions for the prevention and adjuvant treatment of hypertension. In this Review, we provide a summary of the epidemiological research supporting the preventive and antihypertensive effects of major lifestyle interventions (regular physical exercise, body weight management and healthy dietary patterns), as well as other less traditional recommendations such as stress management and the promotion of adequate sleep patterns coupled with circadian entrainment. We also discuss the physiological mechanisms underlying the beneficial effects of these lifestyle interventions on hypertension, which include not only the prevention of traditional risk factors (such as obesity and insulin resistance) and improvements in vascular health through an improved redox and inflammatory status, but also reduced sympathetic overactivation and non-traditional mechanisms such as increased secretion of myokines.

Predictive Performance of Pender's Health Promotion Model for Hypertension Control in Iranian Patients

Objective

The main aim of this study was to investigate predictive factors of adherence to the hypertension control therapeutic and lifestyle recommendations in a sample of Iranian patients based on the constructs of Pender’s health promotion model.

Patients and Methods

The cross-sectional study was performed on the 380 hypertensive patients who were referred to the health centers, the emergency and internal diseases departments of the Bagheralolom Hospital, and the cardiologists’ offices in the city of Ahar, North West of Iran. Data were collected using a researcher designed questionnaire based on the Pender’s health promotion model. The Pearson correlation test, multivariate linear regression, and independent t-test were used for data analysis.

Results

Mean age of the recruited patients was 52.94 (SD=12.8). Perceived benefits, perceived barriers, situational influences, and interpersonal influences (adjusted R²= 0.525) explained 52.5% of the observed variation in adherence to hypertension control recommendations.

Conclusion

Successful hypertension control in patients with chronic morbidity need to be based on sound data about major determinants of the relevant health/illness behaviors. The study findings revealed that the Pender’s health promotion model could be applicable as a theoretical framework to identify major determinants of adherence to hypertension control recommendations. Future cross-cultural validation of the study findings in more representative and larger sample sizes could add to the legitimacy of the evidence surrounding self-care practices in hypertensive patients.

Future possibilities for artificial intelligence in the practical management of hypertension

The use of artificial intelligence in numerous prediction and classification tasks, including clinical research and healthcare management, is becoming increasingly more common. This review describes the current status and a future possibility for artificial intelligence in blood pressure management, that is, the possibility of accurately predicting and estimating blood pressure using large-scale data, such as personal health records and electronic medical records. Individual blood pressure continuously changes because of lifestyle habits and the environment. This review focuses on two topics regarding controlling changing blood pressure: a novel blood pressure measurement system and blood pressure analysis using artificial intelligence. Regarding the novel blood pressure measurement system, we compare the conventional cuff-less method with the analysis of pulse waves using artificial intelligence for blood pressure estimation. Then, we describe the prediction of future blood pressure values using machine learning and deep learning. In addition, we summarize factor analysis using "explainable AI" to solve a black-box problem of artificial intelligence. Overall, we show that artificial intelligence is advantageous for hypertension management and can be used to establish clinical evidence for the practical management of hypertension.

The safety and effectiveness of mind body interventions for women with pregnancy induced hypertension and or preeclampsia: A systematic review and meta-analysis

OBJECTIVES

To undertake a systematic review of the safety and effectiveness of mind body approaches for women with hypertensive disorders in pregnancy (HDP).

DESIGN

A search was undertaken of databases from inception to 2019 for randomised and quasi randomised controlled trials.

MAIN OUTCOME MEASURES

The primary outcome was a reduction in systolic and / or diastolic blood pressure for women with hypertension and or preeclampsia in pregnancy.

RESULTS

121 studies were identified and eight studies were included in this review. These included mind body interventions examining yoga, guided imagery, relaxation, music, and acupuncture for HDP. Two studies of relaxation found a reduction in systolic (MD -11.3, 95%CI -13.23 to -9.39) and diastolic blood pressure (MD -6.59, 95%CI -9.43 to -3.75) and reduced stress (MD -11.4, 95%CI -16.5 to -6.3). In one study of yoga, the risk of developing HDP was reduced (RR 0.28, 95% CI 0.09 to 0.91, 59 women) and a second study found a reduction in stress at the end of the intervention of yoga. One trial of guided imagery found a reduction in mean arterial blood pressure compared to the control (4.35, 95% -8.04 to -0.66, p=0.02). Overall there was no effect on the development of preeclampsia, use of anti-hypertensive medication and any neonatal outcomes from the interventions evaluated. Few trials reported on safety outcomes, one trial of acupuncture reported one case of placental abruption and three cases of acupuncture related side effects.

CONCLUSION

Few high quality trials have examined the effectiveness and safety of mind body interventions to manage HDP. Relaxation, yoga, guided imagery and music may have some potential benefit. Safety issues are completely unclear and thus the risk-benefit ratio of all interventions could not be determined. Further research is recommended.

The global epidemiology of hypertension

Hypertension is the leading cause of cardiovascular disease and premature death worldwide. Owing to the widespread use of antihypertensive medications, global mean blood pressure (BP) has remained constant or has decreased slightly over the past four decades. By contrast, the prevalence of hypertension has increased, especially in low- and middle-income countries (LMICs). Estimates suggest that 31.1% of adults (1.39 billion) worldwide had hypertension in 2010. The prevalence of hypertension among adults was higher in LMICs (31.5%, 1.04 billion people) than in high-income countries (28.5%, 349 million people). Variations in the levels of risk factors for hypertension, such as high sodium intake, low potassium intake, obesity, alcohol consumption, physical inactivity and unhealthy diet, may explain some of the regional heterogeneity in hypertension prevalence. Despite the increasing prevalence, the proportions of hypertension awareness, treatment and BP control are low, particularly in LMICs, and few comprehensive assessments of the economic impact of hypertension exist. Future studies are warranted to test implementation strategies for hypertension prevention and control, especially in low-income populations, and to accurately assess the prevalence and financial burden of hypertension worldwide.

The psychometric properties of the Hypertensive Treatment Adherence Scale

BACKGROUND

Hypertension (HTN) is a public concern and treatment adherence has a key role in its management. This study was conducted to develop and test the reliability and validity of the Hypertensive Treatment Adherence scale (HTA-scale).

METHODS

This was a cross-sectional and methodological study. After item generation using a qualitative study and literature review, the scale was developed. The psychometric properties of the scale were evaluated using face, content, construct, and criterion validity and reliability.

RESULTS

Data analysis showed that the HTA-scale had acceptable face and content validity. The scale had excellent stability [Intraclass correlation coefficient (ICC) = 0.74] and good acceptability and internal consistency (Cronbach's a = 0.76). Exploratory factor analysis (EFA) showed that the HTA-scale consisted of 6 meaningful subscales including medication adherence and monitoring, adherence to safe diets, avoiding unsafe diets, self-medication, activity, and smoking. Participants in the controlled blood pressure group had significantly higher HTA-scale scores than the uncontrolled blood pressure group. At the cut-off point of 86, the scale had significant sensitivity and specificity.

CONCLUSION

All of the psychometric properties of the HTA-scale achieved the standard level and were sufficient to recommend this scale for patients with HTN.

Can verbal suggestions strengthen the effects of a relaxation intervention?

Short stress management interventions such as relaxation therapy have demonstrated preliminary effectiveness in reducing stress-related problems. A promising tool to strengthen the effectiveness of relaxation-based interventions is the use of verbal suggestions, as previous research provided evidence that verbal suggestions can induce positive outcome expectancies, facilitate adaptive responses to stress and improve health outcomes. The present experimental proof-of-concept study aimed to investigate the effects of a brief relaxation intervention and specifically the role of verbal suggestions on stress-related outcomes assessed by self-report questionnaires and psychophysiological data. 120 participants (mean age = 22.1 years) were randomized to one of four intervention conditions: a brief relaxation intervention plus verbal suggestions condition, a brief relaxation intervention only condition, a verbal suggestions only condition, and a control condition. Afterwards, participants were subjected to a psychosocial stress challenge to assess reactivity to a stressful event. Immediately after both relaxation interventions (with and without verbal suggestions), lower self-reported state anxiety was found compared to the control condition, but no differences were observed in response to the stressor. The verbal suggestions only condition did not impact state anxiety. No significant effects were found for verbal suggestion interventions on cortisol, alpha amylase, heart rate and skin conductance. This is the first study investigating the role of verbal suggestions in the effectiveness of a brief relaxation intervention. Although this experimental proof-of-concept study provides support for the effectiveness of a brief relaxation intervention in lowering state anxiety directly after the intervention, the effects did not impact the response to a subsequent stressor and we did not observe any evidence for the add-on effectiveness of verbal suggestions. The effectiveness of brief relaxation interventions on stress responses should be investigated further in future research by incorporating interventions that are tailored to the specific stress challenge and various types of verbal suggestions.

Association of home blood pressure with sleep and physical and mental activity, assessed via a wristwatch-type pulsimeter with accelerometer in adults

This study aimed to examine the associations between home blood pressure (HBP) and sleep and activity assessed using data obtained via a wristwatch-type pulsimeter with accelerometer (Pulsense®) using original software. We recruited 28 elderlies and 40 employees aged 24-81 years who were not on hypotensive agents and sleeping drugs. Sleep, activity, and HBP were measured consecutively over a 5-7-day period. Body mass index (BMI), base heart rate (HR₀), and age showed significant correlation with HBP in a simple and multiple linear regression analysis. HR₀ was positively, and log deep sleep duration, negatively correlated with HBP in the adjusted multiple linear regression analysis. Physical and mental activities were negatively correlated with systolic blood pressure (SBP) in a simple linear regression, but high physical and mental activities tend to reduce deep sleep duration. Self-recorded sleep duration had no relationship with HBP. In conclusion, HR₀, BMI, age, deep sleep duration, and activity showed relationships with HBP. Using this type of wristwatch and observing daily sleep and activity data with HBP measurement may have important clinical implication.

Combining walking and relaxation for stress reduction-A randomized cross-over trial in healthy adults

Both physical activity and relaxation have stress-relieving potential. This study investigates their combined impact on the relaxation response while considering participants' initial stress level. In a randomized cross-over trial, 81 healthy adults completed 4 types of short-term interventions for stress reduction, each lasting for 1 hr: (1) physical activity (walking) combined with resting, (2) walking combined with balneotherapy, (3) combined resting and balneotherapy, and (4) resting only. Saliva cortisol, blood pressure, state of mood, and relaxation were measured preintervention and postintervention. Stress levels were determined by validated questionnaires. All interventions were associated with relaxation responses in the variables saliva cortisol, blood pressure, state of mood, and subjective relaxation. No significant differences were found regarding the reduction of salivary cortisol (F = 1.30; p = .281). The systolic blood pressure was reduced best when walking was combined with balneotherapy or resting (F = 7.34; p < .001). Participants with high stress levels (n = 25) felt more alert after interventions including balneotherapy, whereas they reported an increase of tiredness when walking was combined with resting (F = 3.20; p = .044). Results suggest that combining physical activity and relaxation (resting or balneotherapy) is an advantageous short-term strategy for stress reduction as systolic blood pressure is reduced best while similar levels of relaxation can be obtained.

Lifestyle Medicine and the Management of Cardiovascular Disease

PURPOSE OF REVIEW

Evidence has clearly demonstrated the importance of lifestyle factors (e.g., diet, physical activity, smoking) in the development of cardiovascular disease (CVD). Interventions targeting these behaviors may improve outcomes for CVD patients. The aim of this review is to summarize the effects of lifestyle interventions in individuals with established CVD.

RECENT FINDINGS

Most recent trials focused on diet, physical activity, stress reduction, or a combination of these. Findings were mixed, but most interventions improved at least some markers of cardiovascular risk. Few studies measured long-term clinical outcomes, but some suggested a possible benefit of stress reduction and multifaceted interventions on cardiovascular events. The benefits of lifestyle change for CVD patients have been established by decades of evidence. However, further research is needed to determine the optimal intensity, duration, and mode of delivery for interventions. Additional studies with long-term follow-up and measurement of clinical outcomes are also needed.

Panic Disorder Comorbidity with Medical Conditions and Treatment Implications

Panic disorder (PD) is unique among the anxiety disorders in that panic symptoms are primarily of a physical nature. Consequently, comorbidity with medical illness is significant. This review examines the association between PD and medical illness. We identify shared pathophysiological and psychological correlates and illustrate how physiological activation in panic sufferers underlies their symptom experience in the context of the fight-or-flight response and beyond a situation-specific response pattern. We then review evidence for bodily symptom perception accuracy in PD. Prevalence of comorbidity for PD and medical illness is presented, with a focus on respiratory and cardiovascular illness, irritable bowel syndrome, and diabetes, followed by an outline for potential pathways of a bidirectional association. We conclude by illustrating commonalities in mediating mechanistic pathways and moderating risk factors across medical illnesses, and we discuss implications for diagnosis and treatment of both types of conditions.

Lay beliefs about hypertension among HIV-infected adults in Kenya

OBJECTIVE

Hypertension affects 23% of Kenyans and is the most prevalent modifiable risk factor for cardiovascular disease. Despite this, hypertension awareness and treatment adherence is very low. We conducted a qualitative study to explore lay beliefs about hypertension among HIV-infected adults to inform the development of culture sensitive hypertension prevention and control program.

METHODS

Eight focus group discussions were held for 53 HIV-infected adults at the HIV clinic in Kenya.

RESULTS

Respondents had difficulties in describing hypertension. Hypertension was considered a temporary illness that is fatal and more serious than HIV. Stress was perceived as a main cause for hypertension with a large majority claiming stress reduction as the best treatment modality. Alcohol and tobacco use were not linked to hypertension. Obesity was cited as a cause of hypertension but weight control was not considered as a treatment modality even though the majority of our participants were overweight. Most participants did not believe hypertension could be prevented.

CONCLUSION

Our findings suggest a limited understanding of hypertension among people living with HIV and points to an urgent need to integrate hypertension education programmes in HIV care facilities in Kenya. To effect change, these programmes will need to tie in the culture meaning of hypertension.

Lifestyle Approaches to White Coat Hypertension

This case presentation illustrates the importance of 24 hour ambulatory blood pressure monitoring in patients with white coat hypertension, as many progress into sustained hypertension over time. Also, it serves as a reminder not to overlook a possible underlying sleep breathing disorder in patients who are not obese or fatigued. Finally, the case provides an opportunity to review the value of non-pharmacological and lifestyle approaches to the treatment of both white coat hypertension and sustained hypertension.

Being as an iceberg: hypertensive treatment adherence experiences in southeast of Iran

BACKGROUND

Treatment adherence is often an important issue in the management of hypertension. Deep understanding of adherence behavior as well as its influential factors can expand knowledge about treatment adherence among hypertensives.

OBJECTIVE

The aim of this study was to explore patients, their families, and healthcare providers' experiences about hypertension treatment adherence in southeast of Iran.

DESIGN

A qualitative study was conducted to explore the experience of patients, family members, and healthcare providers (n=18) by using a conventional content analysis. The purposive sampling method was used. Data were collected through semi-structured and deep interviews.

RESULTS

Data analysis showed that hypertensive treatment adherence in an Iranian context is like an iceberg with two subthemes. The first subtheme relates to the upper and clear part of this iceberg and it consists of two categories, including (1) healthy and (2) unhealthy regimens. The second subtheme associates with under-water and unanticipated part and it consists of four categories, including (1) the nature of disease and treatment, (2) the individual resources, (3) the healthcare organization, and (4) the socio-cultural environment.

CONCLUSIONS

The treatment adherence features emerged in this study can be useful in designing and developing context-based hypertension interventions. Further qualitative and quantitative studies with a closer collaboration between the social, natural, and medical sciences in other Iranian populations are needed to confirm the findings.
