Hypertension awareness and pain reports: data from the NHANES III

Pain, obesity, and physical function in Mexican American older adults during 20 years of follow-up

INTRODUCTION

Pain remains largely undertreated in older adults irrespective of health care setting. Mexican American adults in the United States have a high age-adjusted prevalence of obesity. However, the association of pain and obesity with physical function is understudied in this population.

OBJECTIVE

To examine the association of co-occurring pain and obesity with physical function over 20 years of follow-up in a cohort of older Mexican Americans who scored ≥7 (moderate to high) in the Short Physical Performance Battery (SPPB) test and were nondisabled at baseline.

DESIGN

Longitudinal population-based study.

SETTING

Community-dwelling older adults from Southwestern United States.

PARTICIPANTS

Mexican American adults age 65 years and older.

INTERVENTIONS

Not Applicable.

MAIN OUTCOME MEASURES

Physical function was assessed with the SPPB test (standing balance, timed 8-ft walk, and five repeated timed chair stands). Participants at baseline were divided into four groups: no pain-no obesity (n = 869), obesity only (n = 282), pain only (n = 216), and pain-obesity (n = 159). Generalized Estimating Equation models were used to estimate the odds ratio (OR) and 95% confidence interval (CI) of lower performance in physical function over 20 years as a function of pain-obesity grouping.

RESULTS

Participants with pain only (OR = 1.61, 95% CI = 1.34-1.95) and with co-occurring pain and obesity (OR = 2.32, 95% CI = 1.83-2.95) had significantly greater odds of physical function impairment over those with no pain-no obesity or obesity only, after controlling for all covariates.

CONCLUSION

Older Mexican American adults were at high risk for physical function impairment over time if they had pain or co-occurring pain and obesity. Early assessment and proper pain management as well as maintaining a healthy weight may reduce declines in physical function in older Mexican American adults.

Changes in the prevalence of measures associated with hypertension among Iranian adults according to classification by ACC/AHA guideline 2017

Background

Different definitions have been proposed to categorize hypertension. We aimed to investigate the difference in prevalence of measures associated with hypertension according to the American College of Cardiology/American Heart Association (ACC/AHA) criteria versus Joint National Committee 7 (JNC7) criteria.

Methods

We analyzed the data of 10,000 participants of Yazd Health Study (YaHS) aged 20–69 years. Blood pressure was measured three times with standard protocol defined by ACC/AHA. Prevalence of high blood pressure measure was compared in both definitions and absolute differences reported.

Results

The prevalence of high blood pressure in our measurement was 61.0% according to ACC/AHA, and 28.9% according to JNC 7. The prevalence of self-reported hypertension was 18.6%. Age and sex standardized prevalence rates of high blood pressure measure indicates a 2.4-fold increase in the prevalence rate (30.1% absolute difference) by the ACC/AHA guideline. While the prevalence increased in all age groups, the age group of 20–29 showed the highest relative increase by 3.6 times (10.6% vs. 38.1%). High blood pressure measure among people with diabetes increased from 45.8 to 75.3% with the ACC/AHA guideline. Of the people who had no past history of diagnosed hypertension (n = 7887), 55.1 and 22.7% had high blood pressure measure by ACC/AHA and JNC-7 guidelines, respectively. From JNC7 to ACC/AHA, the overall difference in unawareness about HTN increased by 32.4%.

Conclusion

Prevalence of hypertension associated measures increased over two folds by using the ACC/AHA criteria compared to JNC 7. Also, change in the criteria, reduces awareness of the disease and increases uncontrolled hypertension respectively. More research is needed to determine if the new definitions can affect management of hypertension in societies. Considering local priorities and implication of cost effective may improve implementation of new definitions for hypertension in different countries.

Hypertension, socioeconomic status and depressive symptoms in Chinese middle-aged and older adults: Findings from the China health and retirement longitudinal study

BACKGROUND

This study aimed to examine the effect of diagnosed hypertension on depressive symptoms and socioeconomic status (SES) as moderator in the effect in middle-aged and older adults in China.

METHODS

We used data from the nationally representative survey of China Health and Retirement Longitudinal Study, including 6273 participants free from depressive symptoms at baseline in 2011-12. We assessed the depressive symptoms based on the 10-item Center for Epidemiological Studies Depression scale. We conducted Cox proportional hazards regression models to examine the effect of baseline diagnosed hypertension status on the subsequent depressive symptoms in 2011-15 with the report of Hazards ratios (HRs).

RESULTS

The diagnosed hypertensive participants were more likely to have depressive symptoms than non-hypertensive peers (HR = 1.12, 95% CI: 1.02-1.23) after adjusted for controlled variables. The effect only occurred in the group of low SES, with rural residency (HR = 1.13, 95% CI: 1.02-1.26), below-average household income (HR = 1.14, 95% CI: 1.02-1.26) and primary school or below educational attainment (HR = 1.12, 95% CI: 1.00-1.25).

LIMITATIONS

Measures of the onset or duration of hypertension were not included, which may modify the estimated effects on depressive symptoms.

CONCLUSIONS

Diagnosed hypertension is a chronic stressor leading to depressive disorders, and the responses to this stressor merely occurred among the low socioeconomic individuals. Our findings underscored the importance of examining the connection between mental and physical health in the context of aging and shed lights on the action to developing strategies for detection and management of hypertension that could cause psychological stress, which may contribute to fighting against depressive symptoms, especially in the low SES population.

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.

Symptom burden of adults with type 2 diabetes across the disease course: diabetes & aging study

BACKGROUND

Reducing symptom burden is paramount at the end-of-life, but typically considered secondary to risk factor control in chronic disease, such as diabetes. Little is known about the symptom burden experienced by adults with type 2 diabetes and the need for symptom palliation.

OBJECTIVE

To examine pain and non-pain symptoms of adults with type 2 diabetes over the disease course - at varying time points before death and by age.

DESIGN

Survey follow-up study.

PARTICIPANTS

13,171 adults with type 2 diabetes, aged 30-75 years, from Kaiser Permanente, Northern California, who answered a baseline symptom survey in 2005-2006.

MAIN MEASURES

Pain and non-pain symptoms were identified by self-report and medical record data. Survival status from baseline was categorized into ≤ 6, >6-24, or alive >24 months.

KEY RESULTS

Mean age was 60 years; 48 % were women, and 43 % were non-white. Acute pain was prevalent (41.8 %) and 39.7 % reported chronic pain, 24.6 % fatigue, 23.7 % neuropathy, 23.5 % depression, 24.2 % insomnia, and 15.6 % physical/emotional disability. Symptom burden was prevalent in all survival status categories, but was more prevalent among those with shorter survival, p< .001. Adults ≥ 60 years who were alive >24 months reported more physical symptoms such as acute pain and dyspnea, whereas participants <60 years reported more psychosocial symptoms, such as depressed mood and insomnia. Adjustment for duration of diabetes and comorbidity reduced the association between age and pain, but did not otherwise change our results.

CONCLUSIONS

In a diverse cohort of adults with type 2 diabetes, pain and non-pain symptoms were common among all patients, not only among those near the end of life. However, symptoms were more prevalent among patients with shorter survival. Older adults reported more physical symptoms, whereas younger adults reported more psychosocial symptoms. Diabetes care management should include not only good cardiometabolic control, but also symptom palliation across the disease course.

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.

Factors associated with chronic noncancer pain in the Canadian population

Chronic noncancer pain (CNCP) is a prevalent health problem with pervasive negative effects on the individual's quality of life. Previous epidemiological studies of CNCP have suggested a number of individual biological, psychological and societal correlates of CNCP, but it has rarely been possible to simultaneously compare the relative strengths of many such correlates in a Canadian population sample. With data provided by the 1996/1997 Canadian National Population Health Survey, ordinal logistic regression was used to examine the extent to which a number of population variables are associated with CNCP in a large (n=69,365) dataset. The analysis revealed cross-sectional correlations of varying strengths between CNCP and 27 factors. Increasing age, low income, low educational achievement, daily cigarette smoking, physical inactivity and abstention from alcohol were among the factors found to increase CNCP risk. The considerable impact of distress and depression on CNCP are also highlighted. A number of comorbid medical illnesses increased CNCP risk, including some (such as chronic obstructive pulmonary disease, epilepsy and thyroid disease) that have not hitherto been associated with pain. White race and the affirmation of an important role for spirituality or faith reduced CNCP risk. In contrast to some previous studies, female sex did not emerge as an independent CNCP risk. The present exploratory analysis describes associations between CNCP and a number of characteristics from several domains, thus suggesting many areas for further research.

The impact of perceived hypertension status on anxiety and the white coat effect

BACKGROUND

The white coat effect can lead to overdiagnosis of hypertension and unnecessary pharmacologic treatment. Mechanisms underlying the white coat effect remain poorly understood but are critical to improving the accuracy of clinic blood pressure measurement.

PURPOSE

This study investigated whether perceived hypertension status was associated with state anxiety levels during a clinic visit and the magnitude of the white coat effect, independent of true blood pressure status.

METHODS

This observational study included 214 normotensive and mildly hypertensive participants who were 18 to 80 years old, had no cardiac history, and were willing to discontinue antihypertensive medications for 8 weeks. Participants underwent 36 hr ambulatory blood pressure monitoring and physician blood pressure measurement. Outcome measures were state anxiety reported during the clinic visit and the white coat effect.

RESULTS

An analysis of covariance indicated that participants who perceived themselves as hypertensive reported greater state anxiety (p<.001) and showed larger white coat effects (ps<.01) compared with those who perceived themselves as normotensive. True hypertension status based on ambulatory blood pressure was not related to either outcome. Anxiety accounted for approximately 19% of the association between perceived hypertension status and the white coat effect.

CONCLUSIONS

These findings suggest that the perception of being hypertensive is associated with greater anxiety during clinic blood pressure measurement and a larger white coat effect, independent of the true blood pressure level. Anxiety appears to be a mechanism by which perceived hypertension status contributes to the white coat effect.

The role of ischaemia and pain in the blood pressure response to exercise stress testing in patients with coronary heart disease

Silent myocardial ischaemia is a common phenomenon in patients with coronary heart disease. However, very little is known about the underlying mechanisms of silent ischaemia. One potential pathway that may contribute to this absence of pain is increased blood pressure. The main aim of the current study was to assess the associations among blood pressure, pain and ischaemia in patients undergoing a standard exercise stress test. We hypothesized that patients who experienced chest pain during exercise would have lower baseline and peak blood pressures compared to those who did not experience chest pain. A total of 1,355 patients (418 women) who underwent a single-photon emission computed tomography treadmill exercise stress test and had not experienced a cardiac event in the past 2 weeks participated in the current study. Myocardial perfusion defects were assessed at rest and during the stress challenge. Systolic blood pressure (SBP), diastolic blood pressure, heart rate (HR) and rate pressure product (RPP) were assessed during rest and at peak exercise. There were no main effects of either pain or ischaemia on the baseline cardiovascular variables. Peak exercise data revealed main effects of pain on SBP, RPP and HR, and main effects of ischaemia on SBP and RPP, controlling for age, sex, baseline level, medication status and cardiac history. These findings suggest that acute rather than chronic increases in blood pressure may be one mechanism to explain the phenomena of silent myocardial ischaemia in cardiac patients, and may potentially provide a target for future treatment strategies.
