Test and Treat for Prediabetes: A Review of the Health Effects of Prediabetes and the Role of Screening and Prevention

The term prediabetes describes blood glucose levels above the normal range but below the threshold to diagnose type 2 diabetes. Several population health initiatives encourage a test and treat approach for prediabetes. In this approach, screening and identification of individuals with prediabetes should be followed by prompt referral to structured lifestyle modification programs or pharmacologic interventions that have been shown to prevent or delay the progression to type 2 diabetes in clinical trials. Here we provide a critical review of evidence for this test and treat approach by examining health outcomes associated with prediabetes and the availability and effectiveness of lifestyle modification approaches that target prediabetes. We also describe current limitations to the reach and uptake of evidence-based treatment options for prediabetes. Finally, we highlight lessons learned from identifying and labeling other preconditions to consider challenges and opportunities that may arise with increasing awareness of prediabetes as part of routine preventive care.

Risk reduction intervention for raised blood pressure (REVERSE): protocol for a mixed-methods feasibility study

INTRODUCTION

Around 40% of adults have pre-hypertension (blood pressure between 120-139/80-89), meaning they are at increased risk of developing hypertension and other cardiovascular disease-related conditions. There are limited studies on the management of pre-hypertension; however, guidance recommends that it should be focused on lifestyle modification rather than on medication. Self-monitoring of blood pressure could allow people to monitor and manage their risk status and may allow individuals to modify lifestyle factors. The purpose of this study is to determine the feasibility and acceptability, to both healthcare professionals and people with pre-hypertension, of blood pressure self-monitoring.

METHODS AND ANALYSIS

A prospective, non-randomised feasibility study, with a mixed-methods approach will be employed. Eligible participants (n=114) will be recruited from general practices, pharmacies and community providers across Lancashire and South Cumbria. Participants will self-monitor their blood pressure at home for 6 months and will complete questionnaires at three timepoints (baseline, 6 and 12 months). Healthcare professionals and participants involved in the study will be invited to take part in follow-up interviews and a focus group. The primary outcomes include the willingness to engage with the concept of pre-hypertension, the acceptability of self-monitoring, and the study processes. Secondary outcomes will inform the design of a potential future trial. A cost-analysis and cost-benefit analysis will be conducted.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from London-Fulham NHS Research Ethics Committee, the University of Central Lancashire Health Ethics Review Panel and the HRA. The results of the study will be disseminated via peer-reviewed publications, feedback to service users and healthcare professionals, and to professional bodies in primary care and pharmacy.

The effects of labelling and health identity on subjective health

OBJECTIVES

Labels are used to describe people every day, and these labels can affect people's subjective health. However, little is known about how existing health identity (i.e., stable identification with being a healthy person) shapes these effects. This study examined the effect of health-related labelling on subjective health, and the potential role of existing health identity in moderating this association.

METHODS

Participants (N = 309) first answered questions related to their health identity, namely, the extent to which they identified with being a healthy person. Next, they were presented with a series of scenarios reflecting healthy (n = 154) or unhealthy (n = 155) labels. Participants' subjective health ratings were then measured using a self-report scale ranging from (0) "Worst health among age" to (100) "Best health among age."

RESULTS

Beyond chronological age effects, exposure to healthy labels was associated with higher ratings of subjective health. Participants with a greater health identity showed an amplified positive response to being labelled a healthy person.

CONCLUSIONS

Social-cognitive processes, both in terms of stable identity and situational labelling, inform subjective health. These perceptions may impact actual health downstream. Our results suggest that health identity and health-related labels may be used in future interventions to bolster objective health outcomes.

Determinants of self-reported hypertension among women in South Africa: evidence from the population-based survey

Background

Hypertension (HTN), characterized by an elevation of blood pressure, is a serious public health chronic condition that significantly raises the risks of heart, brain, kidney, and other diseases. In South Africa, the prevalence of HTN (measured objectively) was reported at 46.0% in females, nonetheless little is known regarding the prevalence and risks factors of self-reported HTN among the same population. Therefore, the aim of this study was to examine determinants of self-reported HTN among women in South Africa.

Methods

The study used data obtained from the 2016 South African Demographic and Health Survey. In total, 6,027 women aged ≥ 20 years were analyzed in this study. Self-reported HTN was defined as a case in which an individual has not been clinically diagnosed with this chronic condition by a medical doctor, nurse, or health worker. Multiple logistic regression models were employed to examine the independent factors of self-reported HTN while considering the complex survey design.

Results

Overall, self-reported HTN was reported in 23.6% (95% confidence interval [CI], 23.1–24.1) of South African women. Being younger (adjusted odds ratio [aOR], 0.04; 95% CI, 0.03–0.06), never married (aOR, 0.69; 95% CI, 0.56–0.85), and not covered by health insurance (aOR, 0.74; 95% CI, 0.58–0.95) reduced the odds of self-reported HTN. On the other hand, being black/African (aOR, 1.73; 95% CI, 1.17–2.54), perception of being overweight (aOR, 1.72; 95% CI, 1.40–2.11), and perception of having poor health status (aOR, 3.53; 95% CI, 2.53–5.21) and the presence of other comorbidities (aOR, 7.92; 95% CI, 3.63–17.29) increased the odds of self-reported HTN.

Conclusions

Self-reported HTN was largely associated with multiple sociodemographic, health, and lifestyle factors and the presence of other chronic conditions. Health promotion and services aiming at reducing the burden of HTN in South Africa should consider the associated factors reported in this study to ensure healthy aging and quality of life among women.

Dediagnosing - a novel framework for making people less ill

Diagnosing constitutes a substantial part of healthcare work and triggers a wide range of actions including the prescription of medicines. Dediagnosing is proposed as a novel framework for removing diagnoses that do not contribute to the reduction of persons' suffering and should be introduced to make people less ill. Dediagnosing comes together with other efforts to reduce overuse, such as deimplementation, deprescribing, decommissioning, and disinvestment. Because diagnoses may influence identity construction and social rights, dediagnosing must be conducted in close collaboration with the patient.

Blood pressure categories defined by the 2017 ACC/AHA guideline and all-cause mortality: a national cohort study in China and meta-analysis

The 2017 American College of Cardiology/American Heart Association guideline recommends a lowered threshold for hypertension diagnosis. Nonetheless, the association of blood pressure (BP) groups defined by the new guideline and all-cause mortality has not been fully estimated, especially in general Chinese. Based on the China Health and Retirement Longitudinal Study (CHARLS) during 2011-2018, 12,964 participants aged 45 years or older at baseline were enrolled for a follow-up of 7 years. Cox proportional hazards models were used to examine the relationship of BP classifications with all-cause mortality, with normal BP (<120/80 mmHg) as a reference. Afterwards, eligible studies shed light in this field were searched in public databases, and meta-analysis was conducted. In CHARLS, there were 41.21% and 16.08% individuals with stage 2 hypertension and stage 1 hypertension, respectively. During the follow-up, 1293 death occurred. The redefined stage 1 (130-139/80-89 mmHg) and stage 2 hypertension (≥140/≥90 mmHg) were found to have increased risk of death in the crude model, but only stage 2 hypertension maintained statistically significance after adjustment. Furthermore, meta-analysis including CHARLS and nine other prospective studies, with a total of 290,609 participants followed up for 3,081,532 person-years, resulted in similar results (combined hazard ratio (95% confidence interval) was 1.07 (0.99-1.15) for stage 1 hypertension, and 1.39 (1.25-1.53) for stage 2 hypertension). The present study detected that individuals with stage 2 and stage 1 hypertension had increased likelihood to die from any cause, but only the former association achieved statistically significance. Further cohorts with long-term follow-up duration are warranted, especially in China.

Intersectional Discrimination and Change in Blood Pressure Control among Older Adults: The Health and Retirement Study

BACKGROUND

Associations between multiple forms of discrimination and blood pressure control in older populations remain unestablished.

METHODS

Participants were 14582 non-institutionalized individuals (59% women) in the Health and Retirement Study aged at least 51 years (76% Non-Hispanic White, 15% Non-Hispanic Black, 9% Hispanic/Latino). Primary exposures included the mean frequency of discrimination in everyday life, intersectional discrimination (defined as marginalization ascribed to more than one reason), and the sum of discrimination over the lifespan. We assessed whether discrimination was associated with change in measured hypertension status (N=14582) and concurrent medication use among reported hypertensives (N=9086) over four years (2008-2014).

RESULTS

There was no association between the frequency of everyday discrimination and change in measured hypertension. Lifetime discrimination was associated with higher odds of hypertension four years later among men (OR: 1.21, 95% CI: 1.08, 1.36) but not women (OR: 0.98, 95% CI: 0.86, 1.13). Only among men, everyday discrimination due at least two reasons was associated with a 1.44 (95% CI: 1.03, 2.01)-fold odds of hypertension than reporting no everyday discrimination; reporting intersectional discrimination was not associated with developing hypertension among women (OR: 0.91, 95% CI: 0.70, 1.20). All three discriminatory measures were inversely related to time-averaged antihypertensive medication use, without apparent gender differences (e.g., OR for everyday discrimination-antihypertensive use associations: 0.85, 95% CI: 0.77, 0.94)).

CONCLUSIONS

Gender differences in marginalization may more acutely elevate hypertensive risk among older men than similarly aged women. Experiences of discrimination appear to decrease the likelihood of antihypertensive medication use among older adults overall.

Stage 1 hypertension defined by the 2017 ACC/AHA guidelines and neonatal outcomes: Systematic review and meta-analysis

BACKGROUND

In 2017, the American College of Cardiology/ American Heart Association (ACC/AHA) guidelines redefined the threshold of high blood pressure (BP) for non-pregnant adults. Several studies aimed to determine whether lowering these thresholds should be considered for pregnancies to prevent poor neonatal outcomes, but the results were inconclusive.

METHODS

We perform a systematic review and meta-analysis to evaluate the association between BP groups defined by the 2017 ACC/AHA guidelines and pregnancy outcomes. Relevant literature was searched in PubMed, Google Scholar, Embase, and Web of Science up to 18 May 2021.

RESULTS

Sixteen eligible studies from twelve articles with a total of 303,131 pregnancies were identified, encompassing 233,084, 20,859, 39,379 individuals with normal BP, elevated BP, and stage 1 hypertension, respectively. When compared with normal BP, the combined odds ratio (95% confidence interval) of elevated BP for adverse pregnancy outcomes was not significant; whereas, that of stage 1 hypertension were 1.25 (1.13-1.39), 1.16 (1.03-1.31), 1.50 (1.28-1.77) and 1.12 (1.00-1.25) for preterm delivery, small for gestational age, low birth weight, and early-term delivery, respectively.

CONCLUSION

Our results indicated that stage 1 hypertension increased the risk of poor neonatal outcomes, highlighting the importance of recognition of stage 1 hypertension as a risk indicator for poor pregnancy outcomes.

Benefits and Harms of Hypertension and High-Normal Labels: A Randomized Experiment

BACKGROUND

Recent US guidelines lowered the threshold for diagnosing hypertension while other international guidelines use alternative/no labels for the same group (blood pressure [BP], <140/90 mm Hg). We investigated potential benefits and harms of hypertension and high-normal BP labels, compared with control, among people at lower risk of cardiovascular disease.

METHODS

We conducted a randomized experiment using a national sample of Australians (n=1318) 40 to 50 years of age recruited from an online panel. Participants were randomized to 1 of 3 hypothetical scenarios where a general practitioner told them they had a BP reading of 135/85 mm Hg, using either hypertension/high-normal BP/control (general BP description) labels. Participants were then randomized to receive an additional absolute risk description or nothing. Primary outcomes were willingness to change diet and worry. Secondary outcomes included exercise/medication intentions, risk perceptions, and other psychosocial outcomes.

RESULTS

There was no difference in willingness to change diet across label groups (P=0.22). The hypertension label (mean difference [MD], 0.74 [95% CI, 0.41-1.06]; P<0.001) and high-normal BP label (MD, 0.45 [95% CI, 0.12-0.78]; P=0.008) had increased worry about cardiovascular disease risk compared with control. There was no evidence that either label increased willingness to exercise (P=0.80). However, the hypertension (MD, 0.20 [95% CI, 0.04-0.36]; P=0.014), but not high-normal label (MD, 0.06 [95% CI, -0.10 to 0.21]; P=0.49), increased willingness to accept BP-lowering medication compared with control. Psychosocial differences including lower control, higher risk perceptions, and more negative affect were found for the hypertension and high-normal labels compared with control. Providing absolute risk information decreased willingness to change diet (MD, 0.25 [95% CI, 0.10-0.41]; P=0.001) and increase exercise (MD, 0.28 [95% CI, 0.11-0.45]; P=0.001) in the hypertension group.

CONCLUSIONS

Neither hypertension nor high-normal labels motivated participants to change their diet or exercise more than control, but both labels had adverse psychosocial outcomes. Labeling people with systolic BP of 130 to 140 mm Hg, who are otherwise at low risk of cardiovascular disease, may cause harms that outweigh benefit.

The contributions of hypertension diagnosis and blood pressure control to subjective life expectancy in a representative sample of older U.S. adults

OBJECTIVES

High blood pressure (BP) or hypertension, a major risk factor for death and disease, is pervasive among older adults. While reducing BP to targeted levels can prevent adverse outcomes, rates of successful BP control remain suboptimal, and it is unclear whether older adults recognize its proven benefits. The current study sheds light on older adults' beliefs about the consequences of hypertension and benefits of BP control by examining how their self-reports of hypertension diagnosis and BP control, as well as measured BP, contribute to subjective life expectancy (SLE), their perceived probability of surviving to a target age.

METHODS

In a representative sample of U.S. adults ages 50-89 from the 2006-2014 Health and Retirement Study (n=18,979 respondents), we analyze SLE using generalized linear regression.

RESULTS

Diagnosed hypertension is associated with lower SLE, regardless of measured BP. Among diagnosed hypertensives, those who self-report controlled BP expect to live longer than those who do not. Finally, about one in ten older adults have high measured BP but have never been diagnosed with hypertension, and most diagnosed hypertensives with uncontrolled measured BP self-report their BP as controlled.

DISCUSSION

Older adults appear to recognize the harmful effects of hypertension and the benefits of BP control, but often lack knowledge of their own hypertension and BP control statuses. Health communications should continue to stress the value of BP control, although improvements may require increased hypertension awareness and BP monitoring.

Importance of lifestyle, stress, and chronic diseases in self-rated health of Korean doctors

The quality of medical services and the health of patients can be guaranteed when the doctors are healthy. In this study, we used the data from the 2016 Korean Physician Survey and analyzed the relationship of lifestyle, stress, and chronic diseases status with the self-rated health of Korean doctors. Among 7,631 doctors in Korea, 2,336 (30.6%) reported their self-rated health as ‘good’, 4,462 (58.5%) as ‘moderate’, and 833 (10.9%) as ‘bad’. The multinominal logistic regression analysis, showed that factors related to the self-rated health were age, type of healthcare facility, smoking, exercise, sleep duration, stress, and chronic diseases status. Since doctors’ lifestyle, stress, and chronic disease status were closely related to their self-rated health, it is imperative to prepare measures to protect doctors’ health in an intensive medical environment, where too many patients require treatment, due to the characteristics of the medical system in Korea.

Mood Disorders in Levothyroxine-Treated Hypothyroid Women

Background: Hypothyroidism has several symptoms (weight gain, arrhythmias, mood changes, etc.). The aims of this study were (1) to assess the prevalence of anxiety and depression in levothyroxine-treated hypothyroid women and in women without hypothyroidism; (2) to identify variables associated with anxiety and depression. Methods: A case-control study was performed with 393 women. Case-group: 153 levothyroxine-treated hypothyroid women. Control-group: 240 women without hypothyroidism. Convenience sampling. Instrument: The Hamilton Hospital Anxiety and Depression Scale (HADS), and a sociodemographic questionnaire. Results: The prevalence of anxiety in levothyroxine-treated hypothyroid women was higher than in women without hypothyroidism (29.4% vs. 16.7%, χ² p < 0.001). The prevalence of depression in the case group was higher than in the control group (13.1% vs. 4.6%, χ² p < 0.001). Levothyroxine-treated hypothyroid women were more likely to have anxiety (OR = 2.08, CI: 1.28-3.38) and depression (OR = 3.13, IC = 1.45-6.45). Conclusion: In spite of receiving treatment with levothyroxine, women with hypothyroidism are more likely to have depression and anxiety. Health professionals need to assess the mood of women with hypothyroidism. Although levothyroxine is a good treatment for the symptoms of hypothyroidism, it may not be enough to prevent development or persistence of depression and anxiety by itself.

The diagnosis of asymptomatic disease is associated with fewer healthy days: A cross sectional analysis from the national health and nutrition examination survey

OBJECTIVE

To examine the effect of the diagnosis of asymptomatic disease on health-related quality of life (HRQoL).

DESIGN

Secondary analysis of a national data set.

METHOD

We analysed adult participants in the 2011-2012 National Health and Nutrition Examination Survey (NHANES) of the civilian non-institutionalized US general population. Across three asymptomatic diseases (glucose intolerance, hyperlipidaemia, and hypertension), we examined four groups (without disease; with disease but no diagnosis; with disease and diagnosis but no treatment; and with disease, diagnosis, and treatment). For each asymptomatic disease, we examined group differences in self-rated health (ordinal logistic regression) and Healthy Days outcomes (number of the last 30 days that physical health was not good, mental health was not good, or inactive; regression). Models were adjusted for age, sex, smoking status, insurance status, income, education, race, body mass index, and comorbid conditions.

RESULTS

Analyses included 6012 respondents (glucose intolerance), 2772 respondents (hyperlipidaemia), and 5524 respondents (hypertension). In adjusted models, those who did not know about their disease had the same self-rated health scores as those without the disease, those with the disease without treatment, and those with disease and treatment. In adjusted analyses of the Healthy Days questions, those with unknown disease reported the same number of unhealthy days as those without disease with the exception of glucose intolerance. Conversely, in four of the nine possible comparisons, those with known disease without treatment reported more unhealthy days than those with who did not know about their disease.

CONCLUSIONS

In adjusted analyses, individuals knowing about their asymptomatic disease are more likely to experience decrements in healthy days compared to those without knowledge of their asymptomatic disease. Statement of contribution What is already known on this subject? There has been sparse evidence that diagnosis of asymptomatic diseases is related to reduced health-related quality of life in population studies. Previous studies have included patients receiving treatment, which impedes the ability to isolate the effects of diagnosis from the effects of treatment. What does this study add? This report examines three asymptomatic health conditions: glucose intolerance, hyperlipidaemia, and hypertension. Those who did not know about their health condition generally had the same health-related quality of life scores as those without health conditions. Conversely, those diagnosed with disease but not receiving treatment reported worse health-related quality of life.

General health checks in adults for reducing morbidity and mortality from disease

BACKGROUND

General health checks are common elements of health care in some countries. They aim to detect disease and risk factors for disease with the purpose of reducing morbidity and mortality. Most of the commonly used individual screening tests offered in general health checks have been incompletely studied. Also, screening leads to increased use of diagnostic and therapeutic interventions, which can be harmful as well as beneficial. It is therefore important to assess whether general health checks do more good than harm. This is the first update of the review published in 2012.

OBJECTIVES

To quantify the benefits and harms of general health checks.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, two other databases and two trials registers on 31 January 2018. Two review authors independently screened titles and abstracts, assessed papers for eligibility and read reference lists. One review author used citation tracking (Web of Knowledge) and asked trial authors about additional studies.

SELECTION CRITERIA

We included randomised trials comparing health checks with no health checks in adults unselected for disease or risk factors. We did not include geriatric trials. We defined health checks as screening for more than one disease or risk factor in more than one organ system.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risk of bias in the trials. We contacted trial authors for additional outcomes or trial details when necessary. When possible, we analysed the results with a random-effects model meta-analysis; otherwise, we did a narrative synthesis.

MAIN RESULTS

We included 17 trials, 15 of which reported outcome data (251,891 participants). Risk of bias was generally low for our primary outcomes. Health checks have little or no effect on total mortality (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.97 to 1.03; 11 trials; 233,298 participants and 21,535 deaths; high-certainty evidence, I² = 0%), or cancer mortality (RR 1.01, 95% CI 0.92 to 1.12; 8 trials; 139,290 participants and 3663 deaths; high-certainty evidence, I² = 33%), and probably have little or no effect on cardiovascular mortality (RR 1.05, 95% CI 0.94 to 1.16; 9 trials; 170,227 participants and 6237 deaths; moderate-certainty evidence; I² = 65%). Health checks have little or no effect on fatal and non-fatal ischaemic heart disease (RR 0.98, 95% CI 0.94 to 1.03; 4 trials; 164,881 persons, 10,325 events; high-certainty evidence; I² = 11%), and probably have little or no effect on fatal and non-fatal stroke (RR 1.05 95% CI 0.95 to 1.17; 3 trials; 107,421 persons, 4543 events; moderate-certainty evidence, I² = 53%).

AUTHORS' CONCLUSIONS

General health checks are unlikely to be beneficial.

Hypertension Status and Associations with Self-Rated Health and General Practitioner Health Seeking in a Rural Australian Cohort

Hypertension is the most frequently managed condition by Australian general practitioners (GP). Knowledge of hypertension and blood pressure (BP) values may motivate individuals to seek GP management. Our study aims to determine the associations of knowledge of BP values, BP perception, GP health seeking, and self-rated health (SRH) in a rural population. Two-hundred and seventy-eight (278) residents responded to the health survey on socio-demographic profile, medical history, BP knowledge and perception, SRH, and GP visit frequency. Associations were evaluated using Chi-squared test and multivariate logistic regression. Cohort mean age was 63.6 (12.4) years with 63.3% females. Hypertension (37.8%) was the most common condition. GP visits were made at least once every month (19.1%), every 2–6 months (35.6%), >6 months (11.5%), or only when needed (29.5%). Univariate analyses showed age, education, alcohol consumption, comorbidities, hypertension status, and SRH were significantly associated with visit frequency. After adjustments, hypertension status (OR = 3.6, 95% CI [1.7, 7.9]) and poor SRH (OR = 3.1, 95% CI [1.4, 7.0]) were significantly associated with frequent monthly visits. Our cohort demonstrated that having hypertension and poor self-rated health were associated with frequent monthly GP visits. The perception of high blood pressure does not drive seeking additional GP input.

Do psychological harms result from being labelled with an unexpected diagnosis of abdominal aortic aneurysm or prostate cancer through screening? A systematic review

OBJECTIVE

A potential psychological harm of screening is unexpected diagnosis-labelling. We need to know the frequency and severity of this harm to make informed decisions about screening. We asked whether current evidence allows an estimate of any psychological harm of labelling. As case studies, we used two conditions for which screening is common: prostate cancer (PCa) and abdominal aortic aneurysm (AAA).

DESIGN

Systematic review with narrative synthesis.

DATA SOURCES AND ELIGIBILITY CRITERIA

We searched the English language literature in PubMed, PsychINFO and Cumulative Index of Nursing and Allied Health Literature (CINAHL) for research of any design published between 1 January 2002 and 23 January 2017 that provided valid data about the psychological state of people recently diagnosed with early stage PCa or AAA. Two authors independently used explicit criteria to review and critically appraise all studies for bias, applicability and the extent to which it provided evidence about the frequency and severity of harm from labelling.

RESULTS

35 quantitative studies (30 of PCa and 5 of AAA) met our criteria, 17 (48.6%) of which showed possible or definite psychological harm from labelling. None of these studies, however, had either appropriate measures or relevant comparisons to estimate the frequency and severity of psychological harm. Four PCa and three AAA qualitative studies all showed clear evidence of at least moderate psychological harm from labelling. Seven population-based studies found increased suicide in patients recently diagnosed with PCa.

CONCLUSIONS

Although qualitative and population-based studies show that at least moderate psychological harm due to screening for PCa and AAA does occur, the current quantitative evidence is insufficient to allow a more precise estimation of frequency and severity. More sensitive measures and improved research designs are needed to fully characterise this harm. In the meantime, clinicians and recommendation panels should be aware of the occurrence of this harm.

Self-rated health in Senegal: A comparison between urban and rural areas

Introduction

Although the relationship between mortality and self-rated health has been demonstrated in sub-Saharan Africa, information in this area is rudimentary. In Senegal, no study has been undertaken comparing self-rated health between urban and rural areas. The objective of this study is therefore to compare self-rated health and its main predictors in Dakar and in a rural isolated area, Tessekere municipality, taking into account socio-demographic and economic factors, social relations, as well as measures of physical and mental health.

Material and methods

This study was carried out in 2015 on a population sample of 1000 individuals living in Dakar and 500 individuals living in the municipality of Tessekere, constructed using the quota method. Self-rated health, health variables, psychosocial, sociodemographic and economic characteristics were collected during face-to-face interviews. Statistical analyses used were Chi-square tests and binary logistic regressions.

Results

Results show that self-rated health in Senegalese urban area (Dakar) is better than in rural area (Tessekere), but the determinants of self-rated health partly differ between these two environments. Age and gender play a fundamental role in self-rated health as much in Dakar as in Tessekere but diabetes and social support play a role in self-rated health only in urban environment, whereas economic well-being is associated to self-rated health only in rural area.

Conclusion

The analyses carried out in these two environments show that despite the existence of common determinants (age, gender, stress), the determinants for formulating an answer to the question of self-rated health differ. People’s social and cultural environments thus play a fundamental role in the process of rating one’s health and, in the short and long term, in the mortality rate.

The Relationship between Lifestyle Factors and Body Compositionin Young Adults

Background: Little is known of how lifestyle factors might influence on body composition parameters in young adults from Croatia. The main purpose of the present study was to investigate the relationship between the lifestyle factors and body composition in young adults. Methods: In this cross-sectional study, participants were 271 university students (59.0% of women). Body composition was measured by using bioelectric impendance analysis (BIA). Blood pressure and heart rate were measured according to standardized protocol and Mediterranean diet adherence (MD), physical activity (PA) and psychological distress (PD) were assessed with validated questionnaires. Results: Self-rated health (SRH) and PA were inversely associated with weight, body-mass index (BMI), fat-mass percentage and blood pressure in men and with weight, BMI, fat-mass percentage and heart rate in women. Higher levels of SRH and PA were positively associated with fat-free mass percentage in both men and women. Smoking was positively associatedwith BMI and fat-mass percentage in women and with heart rate in men. Alcohol consumption was positively associated with weight and BMI in women and fat-mass percentage and heart rate in men, yet inversely associated with fat-free mass percentage only in men. PD was positively associated with weight and blood pressure in men and with BMI, fat-mass percentage and blood pressure in women. Conclusions: Our study shows that higher levels of SRH, MD and PA are related with healthy body composition parameters in young adults. Special interventions and policies that enhance PA and MD and decrease substance use and misuse (SUM) and PD should be implemented within the university school systems.

Participant-Reported Health Status Predicts Cardiovascular and All-Cause Mortality Independent of Established and Nontraditional Biomarkers: Evidence From a Representative US Sample

Background

Participant‐reported health status is a key indicator of cardiovascular health, but its predictive value relative to traditional and nontraditional risk factors is unknown. We evaluated whether participant‐reported health status, as indexed by self‐rated health, predicted cardiovascular disease, and all‐cause mortality risk excess of 10‐year atherosclerotic cardiovascular disease (ASCVD) risk scores and 5 nontraditional risk biomarkers.

Methods and Results

Analyses used prospective observational data from the 1999–2002 National Health and Nutrition Examination Surveys among those aged 40 to 79 years (N=4677). Vital status was ascertained through 2011, during which there were 850 deaths, 206 from cardiovascular disease (CVD). We regressed CVD and all‐cause mortality on standardized values of self‐rated health in survival models, adjusting for age, sex, education, existing chronic disease, race/ethnicity, ASCVD risk, and standardized biomarkers (fibrinogen, C‐reactive protein [CRP], triglycerides, albumin, and uric acid). In sociodemographically adjusted models, a 1‐SD decrease in self‐rated health was associated with increased risk of CVD mortality (hazard ratio [HR], 1.92; 95% CI, 1.51–2.45; P<0.001), and this hazard remained strong after adjusting for ASCVD risk and nontraditional biomarkers (HR, 1.79; 95% CI, 1.42–2.26; P<0.001). Self‐rated health also predicted all‐cause mortality even after adjustment for ASCVD risk and nontraditional biomarkers (HR, 1.50; 95% CI, 1.35–1.66; P<0.001).

Conclusions

Self‐rated health provides prognostic information beyond that captured by traditional ASCVD risk assessments and by nontraditional CVD biomarkers. Consideration of self‐rated health in combination with traditional risk factors may facilitate risk assessment and clinical care.

Effect of elevated blood pressure on quality of life in children with chronic kidney disease

BACKGROUND

Although hypertension is known to have an adverse impact on health-related quality of life (HRQoL) in adults, little is known about the effects of hypertension and use of antihypertensive medications on HRQoL in hypertensive children with chronic kidney disease (CKD).

METHODS

Cross-sectional and longitudinal assessment of impact of elevated blood pressure (BP) and antihypertensive medication use on HRQoL scores obtained in children enrolled in the Chronic Kidney Disease in Children (CKiD) Study. Blood pressure was measured both manually and by ambulatory blood pressure monitoring. HRQoL was assessed with the PedsQL survey.

RESULTS

The study sample included 551 participants with sufficient data for cross-sectional and longitudinal analyses. Cross-sectional analysis of presence of prehypertension or hypertension and impact on HRQoL found mild associations between elevated BP and HRQoL scores with overall PedsQL parent and child scores averaging 79 vs. 76.5 and 83 vs. 78.5, respectively. However, no associations persisted under longitudinal multivariate analysis.

CONCLUSIONS

Despite apparent small effects of elevated BP on HRQoL at baseline, no association was found between the presence of elevated BP and HRQoL over time in children with mild-to-moderate CKD. In addition, antihypertensive medication use did not appear to have an impact on HRQoL in this population.

Diagnostic labelling influences self-rated health. A prospective cohort study: the HUNT Study, Norway

BACKGROUND

Studies have shown an independent association between poor self-rated health (SRH) and increased mortality. Few studies, however, have investigated any possible impact on SRH of diagnostic labelling.

OBJECTIVE

To test whether SRH differed in persons with known and unknown hypothyroidism, diabetes mellitus (DM) or hypertension, opposed to persons without these conditions, after 11-year follow-up.

METHODS

Prospective population-based cohort study in North-Trøndelag County, Norway, HUNT2 (1995-97) to HUNT3 (2006-08). All inhabitants aged 20 years and older were invited. The response rate was 69.5% in HUNT2 and 54.1% in HUNT3. In total, 34144 persons aged 20-70 years were included in the study population. The outcome was poor SRH.

RESULTS

Persons with known disease had an increased odds ratio (OR) to report poor SRH at follow-up; figures ranging from 1.11 (0.68-1.79) to 2.52 (1.46-4.34) (men with hypothyroidism kept out owing to too few numbers). However, in persons not reporting, but having laboratory results indicating these diseases (unknown disease), no corresponding associations with SRH were found. Contrary, the OR for poor SRH in women with unknown hypothyroidism and unknown hypertension was 0.64 (0.38-1.06) and 0.89 (0.79-1.01), respectively.

CONCLUSIONS

Awareness opposed to ignorance of hypothyroidism, DM and hypertension seemed to be associated with poor perceived health, suggesting that diagnostic labelling could have a negative effect on SRH. This relationship needs to be tested more thoroughly in future research but should be kept in mind regarding the benefits of early diagnosing of diseases.

Is there an association between disease ignorance and self-rated health? The HUNT Study, a cross-sectional survey

OBJECTIVE

To explore whether awareness versus unawareness of thyroid dysfunction, diabetes mellitus or hypertension is associated with self-rated health.

DESIGN

Large-scale, cross-sectional population-based study. The association between thyroid function, diabetes mellitus and blood pressure and self-rated health was explored by multiple logistic regression analysis.

SETTING

The second survey of the Nord-Trøndelag Health Study, HUNT2, 1995-1997.

PARTICIPANTS

33 734 persons aged 40-70 years.

PRIMARY OUTCOME MEASURES

Logistic regression was used to estimate ORs for good self-rated health as a function of thyroid status, diabetes mellitus status and blood pressure status.

RESULTS

Persons aware of their hypothyroidism, diabetes mellitus or hypertension reported poorer self-rated health than individuals without such conditions. Women with unknown and subclinical hypothyroidism reported better self-rated health than women with normal thyroid status. In women and men, unknown and probable diabetes as well as unknown mild/moderate hypertension was not associated with poorer health. Furthermore, persons with unknown severe hypertension reported better health than normotensive persons.

CONCLUSIONS

People with undiagnosed but prevalent hypothyroidism, diabetes mellitus and hypertension often have good self-rated health, while when aware of their diagnoses, they report reduced self-rated health. Use of screening, more sensitive tests and widened diagnostic criteria might have a negative effect on perceived health in the population.

The impact of changes in county public health expenditures on general health in the population

We estimate the effect of changes in the per capita expenditures of county departments of public health on county-level general health status. Using panel data on 40 counties in California (2001–2009), dynamic panel estimation techniques are combined with the Lewbel instrumental variable technique to estimate an aggregate demand for health function that measures the causal cumulative impact that per capita public health expenditures have on county-level general health status. We find that a $10 long-term increase in per capita public health expenditures would increase the percentage of the population reporting good, very good or excellent health by 0.065 percentage points. Each year expenditures were increased would result in ∼24,000 individuals moving from the ‘poor or fair health’ category to the ‘good, very good or excellent health’ category across these 40 counties. In terms of the overall impact of county public health departments on general health status, at current funding levels, each annual expenditure cycle results in over 207,000 individuals being in the ‘good, very good or excellent’ categories of health status rather than the ‘poor or fair’ categories.

Does the previous diagnosis of arterial hypertension affect one´s daily life? Pró-Saúde Study

In addition to damaging several target organs, arterial hypertension may negatively impact patients' activities of daily living. Biological and behavioral mechanisms underlying such limitations have yet to be clarified. The objectives of this study were to investigate whether having been previously told of a hypertension diagnosis is associated with the frequency and duration of temporary limitations in activities of daily living, and whether these relationships differ by gender, age, or socioeconomic position. We analyzed sectional data from 2,666 participants (56% women; 55% with high school or lower schooling) at the baseline phase (1999 - 2001) of a longitudinal investigation of university employees in Rio de Janeiro, Brazil (Pró-Saúde Study), asking participants whether they had ever been diagnosed with hypertension by a health professional, if they had been unable to perform any activities of daily living due to a health problem in the previous 2 weeks, and for how many days that had occurred. Multinomial logistic regression models were fitted for the overall study population and for age, gender, educational level, and per capita household income strata. Associations between hypertension diagnosis and temporary limitations were not observed in the overall study population and in gender, education and income strata. However, there were higher odds of temporary limitations among participants aged 55 years old or more with hypertension diagnosis (adjusted OR = 9.5; 95%CI 1.5 - 58.6), regardless of blood pressure levels and use of antihypertensive medication. Elderly people may keep an attitude of higher vigilance regarding conditions or events potentially worsening their health status.

Influence of renal sympathetic denervation on quality of life

BACKGROUND

Therapy-resistant arterial hypertension causing psychosocial stress and is associated with cardiovascular morbidity and mortality. The aim of the study was to evaluate the effect on quality of life (QoL) in patients with resistant hypertension undergoing renal sympathetic denervation (RSD).

METHODS AND RESULTS

We analyzed responses to the SF-36 Quality of Life Questionnaire provided by patients with resistant arterial hypertension after RSD. Thirty consecutive patients from 2 centers were included in this study, from October 2011 until February 2012. The phone interview was performed after the 3-month follow-up. A significant reduction (26 ± 13.5 mmHg) in systolic blood pressure (BP) was detected at the 3-month follow-up (142.0 ± 15.1 mmHg vs 168.0 ± 13.7 mmHg; P < 0.001). Seventy-five percent of the patients indicated that their health situation was a lot better (better, 21%; equal to, 4%) 3 months after RSD compared to the time before the therapeutic procedure. Furthermore, the majority of patients felt full of pep (always, 29%; mostly, 58%; quite often, 8%; sometimes, 4%), and full of energy (always, 25%; mostly, 54%; quite often, 16.7%; sometimes, 4.2%) after the procedure. Recipients of RSD indicated that they felt more light and healthy, and nearly all recipients (93%) described a loss of anxiety and indisposition.

CONCLUSIONS

This investigation revealed that sufficient BP reduction by RSD and time following therapeutic success lead to significant improvements in patient QoL.

Are there consequences of labeling patients with prehypertension? An experimental study of effects on blood pressure and quality of life

OBJECTIVE

The prehypertension classification was introduced to facilitate prevention efforts among patients at increased risk for hypertension. Although patients who have been told that they have hypertension report worse outcomes than unaware hypertensives, little is known about whether or not prehypertension labeling has negative effects. We evaluated the effects of labeling individuals with prehypertension on blood pressure and health-related quality of life three months later.

METHODS

One hundred adults (aged 19 to 82 [mean=40.0] years; 54% women; 64% racial/ethnic minorities) with screening blood pressure in the prehypertensive range (120-139/80-89 mmHg) and no history of diagnosis or treatment of elevated blood pressure were randomly assigned to either a "Labeled" group in which they were informed of their prehypertension, or an "Unlabeled" group in which they were not informed. Subjects underwent office blood pressure measurement, 24-hour ambulatory blood pressure monitoring and completed self-report questionnaires at baseline and at three months.

RESULTS

Multilevel mixed effects regression analyses indicated that changes in the white coat effect, office blood pressure, mean daytime ambulatory blood pressure, and physical and mental health did not differ significantly between the two groups. Adjusting for age, sex, race/ethnicity and body mass index did not affect the results.

CONCLUSION

These findings suggest that labeling patients with prehypertension does not have negative effects on blood pressure or quality of life. Additional research is needed to develop approaches to communicating with patients about their blood pressure that will maximize the clinical and public health impact of the prehypertension classification.

Associations of lifestyle factors, disease history and awareness with health-related quality of life in a Thai population

Background

The impact of the presence and awareness of individual health states on quality of life (HRQoL) is often documented. However, the impacts of different health states have rarely been compared amongst each other, whilst quality of life data from Asia are relatively sparse. We examined and compared the effects of different health states on quality of life in a Thai population.

Methods

In 2008–2009, 5,915 corporate employees were invited to participate in a survey where HRQoL was measured by the Short Form 36 (SF-36) questionnaire. The adjusted mean SF-36 scores were calculated for each self-reported illness, number of chronic conditions, lifestyle factors and awareness of diabetes and hypertension. The effect sizes (ES) were compared using Cohen's d.

Results

The response rate was 82% and 4,683 (79.1%) had complete data available for analysis. Physical and Mental Component Summary (PCS and MCS) scores decreased as the number of chronic conditions increased monotonically (p<0.0001). Diabetes and hypertension negatively influenced PCS (mean score differences −0.6 and −1.5, p<0.001 respectively) but not MCS, whereas awareness of diabetes and hypertension negatively influenced MCS (−2.9 and −1.6, p<0.005 respectively) but not PCS. Arthritis had the largest ES on PCS (−0.37), while awareness of diabetes had the largest ES on MCS (−0.36). CVD moderately affected PCS and MCS (ES −0.34 and −0.27 respectively). Obesity had a negative effect on PCS (ES −0.27). Exercise positively affected PCS and MCS (ES +0.08 and +0.21 (p<0.01) respectively).

Conclusion

Health promotion to reduce the prevalence of chronic diseases is important to improve the quality of life in Asian populations. Physical activity is an important part of such programs. Awareness of diseases may have greater impacts on mental health than having the disease itself. This has implications for the evaluation of the cost-benefit of screening and labeling of individuals with pre-disease states.

General health checks in adults for reducing morbidity and mortality from disease

BACKGROUND

General health checks are common elements of health care in some countries. These aim to detect disease and risk factors for disease with the purpose of reducing morbidity and mortality. Most of the commonly used screening tests offered in general health checks have been incompletely studied. Also, screening leads to increased use of diagnostic and therapeutic interventions, which can be harmful as well as beneficial. It is, therefore, important to assess whether general health checks do more good than harm.

OBJECTIVES

We aimed to quantify the benefits and harms of general health checks with an emphasis on patient-relevant outcomes such as morbidity and mortality rather than on surrogate outcomes such as blood pressure and serum cholesterol levels.

SEARCH METHODS

We searched The Cochrane Library, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Effective Practice and Organisation of Care (EPOC) Trials Register, MEDLINE, EMBASE, Healthstar, CINAHL, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform (ICTRP) to July 2012. Two authors screened titles and abstracts, assessed papers for eligibility and read reference lists. One author used citation tracking (Web of Knowledge) and asked trialists about additional studies.

SELECTION CRITERIA

We included randomised trials comparing health checks with no health checks in adults unselected for disease or risk factors. We did not include geriatric trials. We defined health checks as screening general populations for more than one disease or risk factor in more than one organ system.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the risk of bias in the trials. We contacted authors for additional outcomes or trial details when necessary. For mortality outcomes we analysed the results with random-effects model meta-analysis, and for other outcomes we did a qualitative synthesis as meta-analysis was not feasible.

MAIN RESULTS

We included 16 trials, 14 of which had available outcome data (182,880 participants). Nine trials provided data on total mortality (155,899 participants, 11,940 deaths), median follow-up time nine years, giving a risk ratio of 0.99 (95% confidence interval (CI) 0.95 to 1.03). Eight trials provided data on cardiovascular mortality (152,435 participants, 4567 deaths), risk ratio 1.03 (95% CI 0.91 to 1.17) and eight trials on cancer mortality (139,290 participants, 3663 deaths), risk ratio 1.01 (95% CI 0.92 to 1.12). Subgroup and sensitivity analyses did not alter these findings.We did not find an effect on clinical events or other measures of morbidity but one trial found an increased occurrence of hypertension and hypercholesterolaemia with screening and one trial found an increased occurence of self-reported chronic disease. One trial found a 20% increase in the total number of new diagnoses per participant over six years compared to the control group. No trials compared the total number of prescriptions, but two out of four trials found an increased number of people using antihypertensive drugs. Two out of four trials found small beneficial effects on self-reported health, but this could be due to reporting bias as the trials were not blinded. We did not find an effect on admission to hospital, disability, worry, additional visits to the physician, or absence from work, but most of these outcomes were poorly studied. We did not find useful results on the number of referrals to specialists, the number of follow-up tests after positive screening results, or the amount of surgery.

AUTHORS' CONCLUSIONS

General health checks did not reduce morbidity or mortality, neither overall nor for cardiovascular or cancer causes, although the number of new diagnoses was increased. Important harmful outcomes, such as the number of follow-up diagnostic procedures or short term psychological effects, were often not studied or reported and many trials had methodological problems. With the large number of participants and deaths included, the long follow-up periods used, and considering that cardiovascular and cancer mortality were not reduced, general health checks are unlikely to be beneficial.

Poor self-rated health is significantly associated with elevated C-reactive protein levels in women, but not in men, in the Japanese general population

OBJECTIVE

Self-rated health (SRH) is associated with risk for mortality, but its biological basis is poorly understood. We examined the association between SRH and low-grade inflammation in a Japanese general population.

METHODS

A total of 5142 men and 11,114 women aged 40 to 69years were enrolled. SRH was assessed by a single question and classified into four categories: good, rather good, neither good nor poor, and poor. Serum high-sensitivity C-reactive protein (hsCRP) levels were measured by the latex-enhanced immunonephelometric method. Elevated CRP was defined as hsCRP level of 1.0mg/L or higher. The association between SRH and elevated CRP was evaluated by using logistic regression with adjustment for age, socioeconomic status (job status, education and marital status), health-related behaviors (smoking status, drinking status, exercise habits and sleep duration), and cardiovascular risk factors (body mass index, systolic blood pressure, total- and HDL-cholesterol, HbA1c and prevalent stroke and/or myocardial infarction).

RESULTS

Compared to persons with good SRH, persons with poor SRH had significantly higher risk for elevated CRP: age-adjusted ORs (95% CIs) were 1.33 (1.01-1.76) in men and 1.66 (1.36-2.02) in women. The significant association remained even after adjustment for socioeconomic status, health-related behaviors and cardiovascular risk factors in women, whereas the significance disappeared in men.

CONCLUSION

Poor SRH is associated with low-grade inflammation in both sexes. In women, but not in men, the association is independent of potential confounders. These findings provide an insight into the biological background of SRH in a general population.

Race differences in the physical and psychological impact of hypertension labeling

BACKGROUND

Blood pressure screening is an important component of cardiovascular disease prevention, but a hypertension diagnosis (i.e., label) can have unintended negative effects on patients' well-being. Despite persistent disparities in hypertension prevalence and outcomes, whether the impact of labeling differs by race is unknown. The purpose of this study was to evaluate possible race differences in the relationship between hypertension labeling and health-related quality of life and depression.

METHODS

The sample included 308 normotensive and unmedicated hypertensive subjects from the Neighborhood Study of Blood Pressure and Sleep, a cross-sectional study conducted between 1999 and 2003. Labeled hypertension was defined (by self-report) as having been diagnosed with high blood pressure or prescribed antihypertensive medications. Effects of labeling and race on self-reported physical and mental health and depressive symptoms were tested using multivariate analysis of covariance, controlling for age, sex, body mass index (BMI), previous medication use, and "true" hypertension status, defined by average daytime ambulatory blood pressure (ABP).

RESULTS

Both black and white subjects who had been labeled as hypertensive reported similarly poorer physical health than unlabeled subjects (P = 0.001). However, labeling was associated with poorer mental health and greater depressive symptoms only among blacks (Ps < 0.05 for the interactions). These findings were not explained by differences in socioeconomic status.

CONCLUSIONS

These results are consistent with previous studies showing negative effects of hypertension labeling, and demonstrate important race differences in these effects. Clinical approaches to communicating diagnostic information that avoid negative effects on well-being are needed, and may require tailoring to patient characteristics such as race.

Gender differences in the association between self-rated health and hypertension in a Korean adult population

Background

Self-rated health (SRH) has been reported as a predictor of mortality in previous studies. This study aimed to examine whether SRH is independently associated with hypertension and if there is a gender difference in this association.

Methods

16,956 community dwelling adults aged 20 and over within a defined geographic area participated in this study. Data on SRH, socio-demographic factors (age, gender, marital status, education) and health behaviors (smoking status, alcohol consumption, physical activity) were collected. Body mass index and blood pressure were measured. Logistic regression models were used to determine a relationship between SRH and hypertension.

Results

32.5% of the participants were found to have hypertension. Women were more likely than men to rate their SRH as poor (p < 0.001), and the older age groups rated their SRH more negatively in both men and women (p < 0.001). While the multivariate-adjusted odds ratio (OR, 95% CI) of participants rating their SRH as very poor for hypertension in men was OR 1.70 (1.13-2.58), that in women was OR 2.83 (1.80-4.44). Interaction between SRH and gender was significant (p < 0.001).

Conclusions

SRH was independently associated with hypertension in a Korean adult population. This association was modified by gender.

Predisease: when does it make sense?

Screening often leads to finding conditions that are not at the stage or level that would classify them as disease but, at the same time, are not at a stage or level at which people can be declared entirely disease free. These "in-between" states have sometimes been designated as "predisease." Examples include precancerous lesions, increased intraocular pressure ("preglaucoma"), prediabetes, and prehypertension. When the goal of preventing adverse health outcomes is kept in mind, this review poses the idea that "predisease" as a category on which to act makes sense only if the following 3 conditions are met. First, the people designated as having predisease must be far more likely to develop disease than those not so designated. Second, there must be a feasible intervention that, when targeted to people with predisease, effectively reduces the likelihood of developing disease. Third, the benefits of intervening on predisease must outweigh the harms in the population. A systematic review of screening guidelines (published in 2003-2010) for 4 sample conditions (cervical cancer, glaucoma, diabetes, and hypertension) is included to assess whether they address these issues, followed by a discussion of the framework questions as they pertain to each condition.

Effects of Training and Detraining on Physical Fitness, Physical Activity Patterns, Cardiovascular Variables, and HRQoL after 3 Health-Promotion Interventions in Institutionalized Elders

The purpose of this study is to assess the effects of different strategies of health on the levels of physical activity (PA), physical fitness (PF), cardiovascular disease (CVD) risk factors and quality of life (QoL) of the institutionalized elderly. Concurrently studies were made of the effect of detraining on these same variables. In this investigation we carried out a prospective longitudinal study with an experimental design, with 1 year plus 3 months of a detraining period. Methodology. (a) A questionnaire with socio-demographic characteristics and a QoL scale (MOS SF-36); (b) Functional Fitness Test to assess PF; (c) An MTI Actigraph to evaluate the PA; (d) Biochemical analysis of blood, blood pressure and bio-impedance. The Main Results Indicated That: (i) ST significantly improved strength and body flexibility and AT the aerobic endurance, agility/dynamic balance and lower strength and flexibility; (ii) Implications of detraining were more evident on the PA groups in the lower body flexibility, which is associated with agility/dynamic balance and lower strength in the AT group; (iii) Cardiovascular variables improved significantly especially blood pressure, cholesterol and glucose in the ST and HDL in the AT group; not having undergone significant changes with the detraining. The results of this thesis contribute positively to highlight the importance of PA in the promotion of health, prevention and reduction of CVD risk factors and the improvement of the PF and QoL.

Association of depression with subsequent mortality, cardiovascular morbidity and incident dementia in people aged 80 and over and suffering from hypertension. Data from the Hypertension in the Very Elderly Trial (HYVET)

BACKGROUND

depression is common in elderly people and may be associated with increased cardiovascular risk and incident dementia.

METHOD

participants in the Hypertension in the Very Elderly Trial (HYVET) completed a depression screening instrument, the Geriatric Depression Score (GDS), at baseline and annually. We examined the association of GDS score with incident stroke, mortality and dementia using Cox proportional hazards models (hazard ratios, HR and 95% confidence intervals, CI) adjusted for treatment group and other potential confounders.

RESULTS

2,656 HYVET participants completed the GDS. The mean follow-up was 2.1 years. A GDS score > or =6 was associated with increased risks of all-cause (HR 1.8, 95% CI 1.4-2.3) and cardiovascular mortality (HR 2.10, 95% CI 1.5-3.0), all stroke (HR 1.8, 95% CI 1.2-2.8) and all cardiovascular events (HR 1.6, 95% CI 1.2-2.1). Risk of incident dementia also tended to be increased (HR 1.28, 95% CI 0.95-1.73). Each additional GDS point at baseline also gave rise to a significantly increased risk of fatal and non-fatal cardiovascular events, all-cause mortality and dementia.

CONCLUSION

there was a strong association between baseline depression scores and later fatal and non-fatal cardiovascular endpoints over a mean follow-up of 2 years in a hypertensive very elderly group. The mechanism of this association warrants further study.

A paradoxical difference in relationship between anxiety, depression and thyroid function in subjects on and not on T4: findings from the HUNT study

OBJECTIVE

There have been conflicting reports on the relationship between thyroid function and mood between studies in subjects on T4 and the general population not on T4. We investigated this relationship in a large catchment area-based study.

DESIGN

We analysed data on serum TSH levels and Hospital Anxiety and Depression Scale (HADS) scores from the HUNT 2 study (age > or = 40 years). Following a test for interaction, analyses were performed separately in females on T4 (n = 1265) and in people not on T4 (males n = 9319 and females n = 17 694).

RESULTS

More females on T4 had high depression and anxiety scores than females not on T4 (depression 18.4%vs. 13.0%, P < 0.001, anxiety 23.4%vs. 18.7%, P < 0.001). In those not on T4, there was an inverse association between serum TSH and depression score in males (B coefficient = -0.61, 95% CI -0.91 to -0.24, P = 0.001) though not in females (B coefficient = -0.07, -0.33 to 0.19), and an inverse association between TSH and anxiety score in both genders (B coefficient for males = 0.68, 95% CI -1.04 to -0.32, P < 0.001; females -0.37, 95% CI -0.67 to -0.08, P = 0.01). In contrast, in females on T4, TSH was positively associated with both depression (B coefficient = +0.27, 95% CI 0.02 to 0.51, P < 0.05) and anxiety (B coefficient = +0.29, 95% CI 0.01 to 0.56, P < 0.05).

CONCLUSIONS

There is a different relationship between thyroid function and depression and anxiety in females on T4 compared with individuals with no thyroid disease. This group also has a higher prevalence of depression and anxiety.

Impact of social position on the effect of cardiovascular risk factors on self-rated health

OBJECTIVES

We assessed the impact of education level on the association between self-rated health and cardiovascular risk factors (blood pressure, glycosylated hemoglobin level, and total cholesterol and triglyceride levels).

METHODS

We used data from the National Health and Nutrition Examination Survey for the years 2001 through 2004 (4015 men and 4066 women). Multivariate analyses were performed with a logistic regression model.

RESULTS

After adjustment for age and ethnicity, among women with high glycosylated hemoglobin levels, the most-educated women had poorer self-rated health compared with the least-educated women (odds ratio [OR] = 4.61; 95% confidence interval [CI] = 2.90, 7.34 vs OR = 2.59; 95% CI = 1.60, 4.20, respectively; interaction test, P = 0.06). The same was true among women with high cholesterol levels (OR = 2.23; 95% CI = 1.40, 3.56 vs OR = 1.13; 95% CI = 0.85, 1.49, respectively; interaction test, P = 0.06). Among men, the impact of education level on the association between self-rated health and any cardiovascular risk factors (measured or self-reported) was not significant.

CONCLUSIONS

The impact of cardiovascular risk factors on self-rated health was higher for highly educated women, which could lead to underestimation of health inequalities between socioeconomic groups when self-rated health is used as an indicator of objective health.

Additional impact of concomitant hypertension and osteoarthritis on quality of life among patients with type 2 diabetes in primary care in Germany - a cross-sectional survey

Background

Patients with type 2 diabetes are likely to have comorbid conditions which represent a high burden for patients and a challenge for primary care physicians. The aim of this cross-sectional survey was to assess the impact of additional comorbidities on quality of life within a large sample of patients with type 2 diabetes in primary care.

Methods

A cross-sectional survey within a large sample (3.546) of patients with type 2 diabetes in primary care was conducted. Quality of life (QoL) was assessed by means of the Medical Outcome Study Short Form (SF-36), self reported presence of comorbid conditions was assessed and groups with single comorbidities were selected. QoL subscales of these groups were compared to diabetes patients with no comorbidities. Group comparisons were made by ANCOVA adjusting for sociodemographic covariates and the presence of depressive disorder.

Results

Of 3546 questionnaires, 1532 were returned, thereof 1399 could be analysed. The mean number of comorbid conditions was 2.1. 235 patients declared to have only hypertension as comorbid condition, 97 patients declared to have osteoarthritis only. Patients suffering from diabetes and hypertension reached similar scores like diabetic patients with no comorbidities. Patients with diabetes and osteoarthritis reached remarkable lower scores in all subscales. Compared to patients with diabetes alone these differences were statistically significant in the subscales representing pain and physical impairment.

Conclusion

The impact of osteoarthritis as an often disabling and painful condition on QoL in patients with type 2 diabetes is higher than the impact of hypertension as common but often asymptomatic comorbidity. Individual care of patients with chronic conditions should aim at both improving QoL and controlling risk factors for severe complications.

The 2007 Canadian Hypertension Education Program recommendations: the scientific summary - an annual update

The present paper summarizes and highlights key messages of the 2007 Canadian Hypertension Education Program recommendations for the management and diagnosis of hypertension. This is the eighth annual update. Important new messages in the 2007 Canadian Hypertension Education Program recommendations emphasize the need for assessing adults with high normal blood pressure on an annual basis and reducing sodium in the diet of Canadians to less than 100 mmol/day. These new recommendations still need to be incorporated into the older but still important considerations for the diagnosis, management and treatment of patients with hypertension, namely, assessing blood pressure in all adults at all appropriate visits, expediting the diagnosis of hypertension, assessing and managing global cardiovascular risk, emphasizing that lifestyle modifications are the cornerstone of antihypertensive therapy, treating to target to achieve optimum cardiovascular risk reduction, using combinations of antihypertensive medications and lifestyle to achieve recommended targets and focusing on adherence to therapy. Minor changes in pharmacological therapies and some new recommendations on routine laboratory tests are discussed.

Correlates of quality of life in primary care patients with hypertension

BACKGROUND

Hypertension has been associated with lower levels of quality of life (QoL). However, the specific correlates of lower QoL in this patient population have remained largely unclear.

METHODS

A cross-sectional design of 1,125 primary care patients with hypertension. We evaluated demographics, health status, subjective health and mental health, health behaviors, health beliefs, knowledge of hypertension treatment, satisfaction with medical care, and quality of medical care as potential predictors of QoL and perceived QoL in the hypothetical absence of hypertension.

RESULTS

Worse financial status, poorer blood pressure control, worse subjective health, mental distress, lack of hypertension diet, and irregular hypertension care were all associated with worse QoL. Worse financial status, poorer blood pressure control, higher body mass index, mental distress, and following a hypertension diet were associated with better QoL in the hypothetical absence of hypertension.

CONCLUSIONS

In addition to taking into consideration well known determinants of QoL, such as financial status, health status, and mental health, physicians need to be aware of the potential tradeoff between following medical recommendations that advocate for a strict diet and the impact these have on patients' QoL. Physicians also need to be aware of the effect of imparting information regarding imbalanced blood pressure on perceived QoL.

How well do people recall risk factor test results? Accuracy and bias among cholesterol screening participants

The authors conducted a community-based cholesterol screening study to examine accuracy of recall for self-relevant health information in long-term autobiographical memory. Adult community residents (N = 496) were recruited to participate in a laboratory-based cholesterol screening and were also provided cholesterol counseling in accordance with national guidelines. Participants were subsequently interviewed 1, 3, or 6 months later to assess their memory for their test results. Participants recalled their exact cholesterol levels inaccurately (38.0% correct) but their cardiovascular risk category comparatively well (88.7% correct). Recall errors showed a systematic bias: Individuals who received the most undesirable test results were most likely to remember their cholesterol scores and cardiovascular risk categories as lower (i.e., healthier) than those actually received. Recall bias was unrelated to age, education, knowledge, self-rated health status, and self-reported efforts to reduce cholesterol. The findings provide evidence that recall of self-relevant health information is susceptible to self-enhancement bias.
