Treatment and blood pressure control in isolated systolic hypertension vs diastolic hypertension in primary care

Cross-sectional surveys on prevalence, treatment and control of hypertension could not satisfactorily distinguish between diastolic hypertension and isolated systolic hypertension because the definition of hypertension included patients under pharmacological treatment. We assessed the situation in the two types of hypertension in general practice in Belgium, based on current blood pressure (BP) measurements and on BP prior to the initiation of drug therapy. Participating physicians enrolled the first 15 at least 55-year-old men visiting the surgery, measured their BP and recorded data on medical history including pretreatment BP, drug utilization, cardiovascular risk factors and target organ damage. Diastolic hypertension was defined as diastolic BP> or =90 mmHg, irrespective of systolic BP, and isolated systolic hypertension as systolic BP > or =140 mmHg and diastolic BP < 90 mmHg. Among 3761 evaluable patients, 74% were hypertensive. Among the 1533 hypertensive patients in whom blood pressure was known prior to treatment (n=965) or who were untreated at the study visit (n=568), 1164 had diastolic hypertension and 369 isolated systolic hypertension. The prevalence of antihypertensive treatment was, respectively, 75 and 25% (P<0.001) in these two types of hypertension. The odds of being treated were independently determined by type of hypertension, severity of hypertension and level of risk (P<0.001). BP was controlled in 25% of all patients with diastolic hypertension and in 13% of all patients with isolated systolic hypertension (P<0.001). About half of the treated patients with systolic hypertension were on a diuretic and/or a calcium-channel blocker. In conclusion, isolated systolic hypertension is less frequently treated than diastolic hypertension, overall BP control is poor and actual drug therapy diverges from recommendations based on placebo-controlled intervention trials.     

Prevalence, awareness, treatment and control of hypertension in Turkey (the PatenT study) in 2003

OBJECTIVE: To determine the distribution of blood pressure (BP) and prevalence, awareness, treatment and control of hypertension in Turkey (PatenT). DESIGN: A population-based cross-sectional epidemiology survey was carried out in 2003. SETTING: Twenty-six cities from seven geographical provinces of Turkey, with proportional representation of urban and rural populations. PARTICIPANTS: A two-stage stratified sampling method was used to select a sample of the adult population over 18 years of age. The total number of participants was 4910. INTERVENTIONS: Data collection and BP measurements were conducted by specifically trained physicians in the households of the participants. MAIN OUTCOME MEASURES: The mean systolic and diastolic BP levels, distribution of blood pressure, prevalence of hypertension (mean systolic BP>or=140 mmHg or mean diastolic BP>or=90 mmHg, or previously diagnosed and/or taking antihypertensive drugs), awareness, treatment and control of hypertension were assessed. RESULTS: The overall age-adjusted and sex-adjusted prevalence of hypertension in Turkey was 31.8%, and it was higher in women than in men (36.1 versus 27.5%, P<0.001). In the whole group, 32.2% had never had their BP measured. Overall, 40.7% of those with hypertension were aware of their diagnosis, only 31.1% were receiving pharmacologic treatment and only 8.1% had their BP under control. The subjects who were aware and treated had a control ratio of 20.7%. CONCLUSIONS: PatenT data indicate that hypertension is a highly prevalent but inadequately managed health problem in Turkey. There is an urgent need for population-based strategies to improve the prevention, early detection and control of hypertension.     

Trends in blood pressure levels, prevalence, awareness, treatment, and control of hypertension in the Czech population from 1985 to 2000/01

OBJECTIVE: To assess trends in blood pressure (BP) levels, prevalence, awareness, and control of hypertension in the Czech population from 1985 to 2000/01. DESIGN: Five independent cross-sectional population surveys conducted in 1985, 1988, 1992, 1997/98, and 2000/01. SETTING: Six, mostly rural, districts of the Czech Republic (Praha-vychod, Benesov, Pardubice, Chrudim, Cheb, and Jindrich?v Hradec). PARTICIPANTS: Men and women aged 25-64 years randomly selected from six districts using the National Population Register/General Health Insurance Company Register (covering, by law, all citizens). The total number of participants was 11 726. MAIN OUTCOME MEASURES: We assessed the mean systolic BP, diastolic BP and pulse pressure, prevalence of hypertension (systolic BP > or = 140 mmHg and/or diastolic BP > or = 90 mmHg, or current treatment with antihypertensive drugs), awareness, treatment, and control of hypertension. RESULTS: Mean systolic BP, diastolic BP, and pulse pressure decreased significantly over a period of 15/16 years. This was associated with a significant decrease in the prevalence of hypertension (from 47.1 to 39.1%, P < 0.001) and with an increase in its awareness (from 49.5 to 67.2%, P < 0.001), use of antihypertensive medication (from 29.3 to 49.3%, P < 0.001), and hypertension control (from 3.9 to 17.0%, P < 0.001). Despite having lower BP values and prevalence of hypertension, females showed higher awareness of the disease, and were more frequently taking antihypertensive medication, and their hypertension was better controlled. CONCLUSION: The reduction in population BP and improved control of hypertension may have contributed to the decrease in cerebrovascular and coronary heart disease mortality in the Czech Republic. The positive longitudinal changes seen in the MONICA regions need not necessarily reflect the situation in the country as a whole. The situation is far from being optimal; a major problem is inadequate treatment of hypertension     

Hypertension confirmation and blood pressure control rates in epidemiological surveys.

BACKGROUND: Scarce knowledge about hypertension confirmation and control after a single blood pressure (BP) measurement is available. The objective of this study was to evaluate hypertension confirmation and control rates after 6-year follow-up in a population-based cohort. METHODS: A cohort of 1748 participants representative of a Spanish population received standardized BP measurements. Systolic BP>or=140 mmHg or diastolic BP>or=90 mmHg was found in 617 participants. Three hundred and thirty-four of them had no history of hypertension and the remaining 283 had been previously diagnosed or received antihypertensive treatment. All were advised to consult their physicians. We discarded for follow-up 109 participants with already well-controlled hypertension (27.8% of all hypertensive participants). We followed 583 participants (94.5% of the cohort) for 6 years (14 died and 20 were lost to follow-up). RESULTS: The diagnosis of hypertension was confirmed during follow-up in 139 (44.4%) of those with no previously known hypertension, making the overall prevalence for the cohort equal to 30.4% (n=531). The hypertension control rate at the end of follow-up was 50.1%, whereas it was 27.9% at baseline. Diabetes was the only factor to be independently associated with good control of hypertension. CONCLUSION: Six years after a single-occasion blood pressure measurement, hypertension was confirmed in almost half of the participants with systolic BP>or=140 mmHg or diastolic BP>or=90 mmHg and no history of hypertension. Hypertension control achieved with this screening procedure is almost double that observed in the baseline examination, and is highest among diabetic participants.     

Prevalence, awareness, treatment and control of hypertension in Portugal. The PAP study.

The objective of this study was to estimate the prevalence and distribution of hypertension and to determine the level of awareness, treatment, and control of hypertension in the Portuguese adult population. The study was conducted in 2003, using a multistage cluster sampling method to select a representative national sample. A total of 5023 adults, aged 18 to 90 years, were examined. Three blood pressure measurements were obtained by trained observers using an OMRON M4-1 sphygmomanometer after a 5-minute seated rest. Information on history of hypertension and use of antihypertensive medication was obtained using a standard questionnaire. Hypertension was defined as mean systolic blood pressure > or =140 mmHg and/or diastolic blood pressure > or =90 mmHg, or use of antihypertensive medication. Overall, 42.1% of the Portuguese adult population aged 18 to 90 years, representing 3,311,830 people, would have hypertension. The age-specific prevalence of hypertension in the three age-groups studied--under 35 years, 35-64 years, and over 64 years--was 26.2%, 54.7% and 79% in men and 12.4%, 41.1% and 78.7% in women respectively. Among hypertensive subjects, only 46.1% were aware of their high blood pressure, 39.0% were taking antihypertensive medication, and 11.2% had their blood pressure controlled (<140/90 mmHg). Our results indicate that hypertension is highly prevalent in Portugal. The percentages of hypertensives who are aware of their condition, are being treated, and whose hypertension is controlled are unacceptably low. These results underscore the urgent need to develop national strategies to improve prevention, detection, and treatment of hypertension in Portugal.     

Prevalence of isolated systolic and isolated diastolic hypertension subtypes in China

BACKGROUND: Isolated systolic hypertension (ISH), more so than any other hypertension subtype, increases the risk for stroke and coronary heart disease. The prevalence of ISH versus other hypertension subtypes in the general Chinese adult population is not known. METHODS: The prevalence of isolated systolic and isolated diastolic hypertension (IDH) was examined in a representative national sample of 15,540 Chinese adults aged 35 to 74 years. Three seated blood pressure (BP) measurements taken after 5 min of rest were averaged and hypertension subtypes were defined among individuals not receiving antihypertensive therapy as follows: ISH as systolic BP >/=140 mm Hg and diastolic BP <90 mm Hg; IDH as systolic BP <140 mm Hg and diastolic BP >/=90 mm Hg; and combined systolic/diastolic hypertension (SDH) as a systolic BP >/=140 mm Hg and diastolic BP >/=90 mm Hg. RESULTS: Overall, 7.6% of the Chinese adult population had ISH, 7.4% had SDH, and 4.4% had IDH. The prevalence of ISH increased with age and was more common in older women than in older men. Stage 1 hypertension was much more prevalent than stage 2 hypertension among all hypertension subtypes. The prevalence of SDH, IDH, and ISH (women, only) were higher in northern China than southern. The prevalence of ISH and SDH (women, only) were higher among rural residents versus urban residents. CONCLUSIONS: These data document high rates of ISH in China. Given the risk of cardiovascular disease associated with ISH, our findings underscore the critical need for enhanced hypertension screening and treatment programs in China.     

Hypertension management and control among English adults aged 65 years and older in 2000 and 2001

OBJECTIVE: To describe blood pressures, and hypertension and its management among older people. DESIGN: Two combined annual cross-sectional surveys. SETTING: England 2000 and 2001. PARTICIPANTS: Nationally-representative sample of 3513 non-institutionalized people aged more than 64 years (elderly). MAIN OUTCOME MEASURES: (1). Use of antihypertensive agents, and hypertension according to two definitions: receiving blood pressure decreasing treatment, or either: systolic blood pressure > or= 160 mmHg or diastolic blood pressure > or= 90 mmHg (old); or systolic blood pressure > or= 140 mmHg or diastolic blood pressure > or=90 mmHg (new). (2). Rates of treatment and control (old: < 160/90 mmHg; new: < 140/85 mmHg). (3). Isolated systolic hypertension stage 1 (systolic blood pressure > or= 140-159 mmHg and diastolic blood pressure < 90 mmHg), or stage 2 (systolic blood pressure > or= 160 mmHg and diastolic blood pressure < 90 mmHg). RESULTS: In 2000/2001, 62 and 81% of elderly adults were hypertensive according to the old and new definitions, respectively. Among those with hypertension (new definition) treatment and control rates were 56 and 19% (control rates among those treated were 36% in men and 30% in women). Of those treated, 54% were receiving one drug, 35% were receiving two, and 10% were receiving three or more drugs. Among untreated hypertensive individuals, 23% had increased systolic and diastolic pressures, 76% had isolated systolic hypertension and 1% had isolated diastolic hypertension. CONCLUSIONS: These data suggest that, according to current guidelines more than 67% of older English adults should receive antihypertensive medication. To pre-empt this situation, population-based strategies to reduce the current rate of increase in blood pressure throughout adult life should be urgently implemented. Only then will the current epidemic of hypertension among the elderly, with the huge cost associated with its management and adverse cardiovascular sequelae, be averted.     

The Systolic Hypertension in the Elderly Program (SHEP): An Intervention Trial on Isolated Systolic Hypertension

The Systolic Hypertension in the Elderly Program (SHEP) is a randomized double-blind placebo-controlled trial to determine if antihypertensive treatment of isolated systolic hypertension (ISH) [systolic blood pressure (SBP)≥160 mmHg, diastolic blood pressure (DBP)<90 mmHg] reduces the 5 year incidence of fatal and nonfatal stroke. Between March 1, 1985 and January 15, 1988, 4736 persons (target 4800) with ISH, age 60 years and over, were enrolled. Potential participants met blood pressure (BP) and age criteria. Those on antihypertensive medication prior to enrollment without documented diastolic hypertension had their medication tapered and discontinued, and then met BP criteria (33% of cohort).

Stepped-care therapy with chlorthalidone and atenolol (alternative, reserpine) or matching placebos was initiated as first and second steps. At baseline the trial population was 43.1% male, 56.9% female; 13.9% black, 86.1% non-black. Also, the mean age was 71.6 years; the mean SBP was 170.3 mmHg and the mean DBP was 76.6 mmHg; 59.8% had codeable resting electrocardiographic abnormalities. The trial is now in follow-up phase with scheduled termination in 1991.     

Prevalence, awareness, treatment and control of hypertension in Portugal: the PAP study

BACKGROUND: The objective of this study was to estimate the prevalence and distribution of hypertension and to determine the status of hypertension awareness, treatment and control in the Portuguese adult population. METHODS: This study was conducted in 2003, and a multistage cluster sampling method was used to select a national representative sample. A total of 5023 adults, age 18-90 years, were examined. Three blood pressure measurements were obtained by trained observers using an OMROM M4-I sphygmomanometer after a 5-min sitting rest. Information on the history of hypertension and the use of antihypertensive medications was obtained by use of a standard questionnaire. RESULTS: Hypertension was defined as a mean systolic blood pressure > or = 140 mmHg and/or diastolic blood pressure > or = 90 mmHg, or the use of antihypertensive medications. Overall, 42.1% of the Portuguese adult population aged 18-90 years, representing 3 311 830 people, had hypertension. The age-specific prevalence of hypertension in the three age groups studied--younger than 35 years, 35-64 years old and older than 64 years--was 26.2, 54.7 and 79% in men and 12.4, 41.1 and 78.7% in women, respectively. Among hypertensive patients, only 46.1% were aware of their high blood pressure, 39.0% were taking antihypertensive medication and 11.2% achieved blood pressure control (< 140/90 mmHg). CONCLUSIONS: Our results indicate that hypertension is highly prevalent in Portugal. The percentages of those with hypertension that are aware, treated and controlled are unacceptably low. These results underscore the urgent need to develop national strategies to improve prevention, detection and treatment of hypertension in Portugal.     

Prevalence, awareness, treatment, control and risk factors of hypertension in Korea: the Ansan study

OBJECTIVES: To determine prevalence, awareness, treatment, and control of hypertension, and its risk factors in an urban Korean population. DESIGN AND SETTING: A cross-sectional survey in Ansan-city, Korea. SUBJECTS AND METHODS: Population-based samples of people aged 18-92 years in Ansan-city, Korea, were selected, yielding 2278 men and 1948 women, and their blood pressures were measured using a highly standardized protocol. Hypertension was defined as a systolic BP > or = 140 mmHg or diastolic BP > or = 90 mmHg or reported treatment with antihypertensive medications, and subclassified according to 1999 WHO-ISH guidelines. Isolated systolic hypertension (ISH) defined as a systolic BP > or = 140 mmHg and diastolic BP < 90 mmHg was also examined. Data were stratified by age and sex. RESULTS: The overall prevalence of hypertension in this study was 33.7%. Among these, 64.9% had Grade 1 hypertension, 22.5% Grade 2, and 12.5% Grade 3. Age-specific prevalence of hypertension increased progressively with age, from 14.19% in 18 to 24 year-olds to 71.39% in those 75 years or older. Hypertension prevalence was significantly higher in men (41.5%) than in women (24.5%) (P < 0.001). Isolated systolic hypertension had significantly lower prevalence (4.33%) within the population, although in the elderly aged 55 years or more it rose by 11.13%. Overall, 24.6% of hypertensive individuals were aware that they had high blood pressure, as much as 78.6% were being treated with antihypertensive medications, and 24.3% were under control. Hypertension awareness as well as treatment and control rates varied by sex, with women higher in all three rates. Multivariate analysis revealed that age, body mass index and abdomen circumference were significantly associated with prevalence of hypertension both in men and women. CONCLUSIONS: Hypertension is highly prevalent in Korea. Despite the high rate of treatment, the rates of awareness and control are relatively low, suggesting the nationwide demand for preventing and controlling high blood pressure in Korea in order to avert an epidemic of cardiovascular disease.     

Evidence for affluence-related hypertension in urban Brazil

Cardiovascular diseases are a leading cause of mortality, and systemic hypertension is a major risk factor. There is an increasing prevalence of hypertension in urban areas of developing countries, due to lifestyle changes associated with economic transition and urbanisation. This study aimed to describe the prevalence and identify risk factors for hypertension in an urban area of South America (Coroa do Meio district in Aracaju, Sergipe State, north-east Brazil) and to examine intraurban hypertension prevalence differences. A cross-sectional survey of 400 adults aged 25 years and over was carried out. Information about health and lifestyle was obtained from a structured interview, followed by assessment of blood pressure (BP) and anthropometry. There were 31.8% (95% confidence interval 27.3-36.6%) participants with hypertension (defined as a systolic BP >140, diastolic BP >90 mmHg, or on antihypertensive medication). Hypertension was independently associated with older age, central obesity (greater waist-to-hip ratio), shorter height and residing in a high socio-economic residential area. Of the four neighbouring areas, hypertension prevalence was 52% in the area of highest income and education, compared with 19, 24 and 34% in the other three areas. The high prevalence of hypertension in this population, and the strong independent association with relative affluence, demonstrates the need for effective primary prevention of hypertension, targeted at modifiable risk factors.     

Prevalence,Awareness, Treatment,and Control of Hypertension among Adult Residents of Tehran: The Tehran Cohort Study

Background:High levels of blood pressure (BP) remain undetected and poorly controlled in large segments of the population leading to an enormous burden in terms of disease and mortality.Objective:We aimed to assess the prevalence, awareness, treatment, and control of hypertension in Tehran.Methods:We used the data of 8,296 adults aged ≥35 years from the Tehran Cohort Study who were enrolled between May 2016 and February 2019. Hypertension was defined as systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg, self-report, and/or current antihypertensive medication use. The age- and sex-weighted prevalence of hypertension and high normal BP was calculated using the 2016 national census. Furthermore, awareness, treatment, and control of hypertension were analyzed.Results:The mean age of the participants was 53.8 ±12.75 years, and 54.0% were women. The weighted prevalence of hypertension and high normal BP were 36.5% and 12.2%, respectively. Among hypertensive individuals, 68.2% were aware of hypertension, 53.3% were receiving medication, and 40.4% had adequate BP control. The awareness, treatment, and control of hypertension were significantly higher in women (72.2% vs. 63.4% [P < 0.001], 55.1% vs 51.1% [P = 0.020], and 42.7% vs. 37.7% [P = 0.004], respectively) and this gap considerably increased with advancing age. Hypertension was more prevalent in northern Tehran but with a better treatment rate and control in the same regions.Conclusion:Despite the high prevalence of hypertension in the adult population of Tehran, the rates of awareness, treatment, and control of hypertension are unsatisfactory and demand comprehensive strategies to improve this situation, especially in younger men.     

Patients with uncontrolled hypertension or concomitant hypertension and benign prostatic hyperplasia

At optimal doses, individual antihypertensive agents lower blood pressure (BP) by an average of 10 mmHg. Many patients with hypertension, including those with stage 3 hypertension, target organ damage, or those at high risk for cardiovascular events and/or adverse effects of high-dose monotherapy, are likely to require combination antihypertensive drug treatment to achieve the recommended systolic/diastolic BP (< 140/90 mmHg). Two studies, a placebo-controlled, double-blind trial (n = 70) and a community-based, open-label trial (n = 491) investigated the antihypertensive efficacy of doxazosin, a long-acting selective alpha1-adrenoceptor blocker, as add-on therapy for uncontrolled hypertension with other antihypertensive medications and in patients with concomitant benign prostatic hyperplasia (BPH) and treated but inadequately controlled hypertension, respectively. The addition of doxazosin to baseline antihypertensive medication(s) significantly lowered BP and had a significantly positive effect on the serum lipid profile. In patients with concomitant BPH, doxazosin significantly improved all BPH symptom scores, regardless of initial symptom severity. Add-on doxazosin sufficiently reduced systolic/diastolic BP such that many patients whose hypertension was previously uncontrolled by other antihypertensive medications were able to reach goal BP (< 140/90 mmHg). Doxazosin as add-on therapy was well tolerated. In conclusion, doxazosin as add-on therapy improves BP control in hypertensive patients not at goal BP and improves lower urinary tract symptoms in patients with concomitant BPH.     

Prevalence, awareness, treatment, and risk factors associated with hypertension in the Iranian population: the national survey of risk factors for noncommunicable diseases of Iran

BACKGROUND: The prevalence of hypertension in the Middle East is not well defined. We examined the prevalence, awareness, treatment, and control of hypertension in Iran. METHODS: The Survey of Risk Factors of Noncommunicable Diseases was conducted in 2005 and contains a representative sample of the Iranian adult population. Of 70,981 participants, the data of 68,250 adults aged 25-64 years who had two valid blood pressure (BP) readings were analyzed to estimate the total prevalence of hypertension (systolic BP >or= 140 mm Hg, diastolic BP >or= 90 mm Hg, or the concurrent use of antihypertensive agents) in the Iranian adult population. RESULTS: Approximately 25% or 6.6 million Iranians aged 25-64 years had hypertension; additionally 46% or 12 million Iranians aged 25-64 years had prehypertension. Among hypertensive patients, 34% were aware of their elevated BP; 25% were taking antihypertensive medications; and of these treated subjects, only 24% had BP values <140/90 mm Hg. Hypertension and prehypertension were associated with age, male gender, obesity, central obesity, hypercholesterolemia, and diabetes. CONCLUSIONS: The prevalence of hypertension and prehypertension is high, and the rates of awareness, treatment, and control are unacceptably low. These results underscore the urgent need to develop national strategies to improve prevention, detection, and treatment of hypertension in Iran.     

Outpatient hypertension treatment, treatment intensification, and control in Western Europe and the United States

BACKGROUND: Hypertension guidelines in the United States tend to have more aggressive treatment recommendations than those in European countries. METHODS: To explore international differences in hypertension treatment, treatment intensification, and hypertension control in western Europe and the United States, we conducted cross-sectional analyses of the nationally representative CardioMonitor 2004 survey, which included 21 053 hypertensive patients visiting 291 cardiologists and 1284 primary care physicians in 5 western European countries and the United States. The main outcome measures were latest systolic and diastolic blood pressure (BP) levels, hypertension control (latest BP level, <140/90 mm Hg), and medication increase (dose escalation or an addition to or switch of drug therapy) for inadequately controlled hypertension. RESULTS: At least 92% of patients in each country received antihypertensive drug treatment. The initial pretreatment BP levels were lowest and the use of combination drug therapy (>or=2 antihypertensive drug classes) was highest in the United States. Multivariate analyses controlling for age, sex, current smoking, and physician specialty indicated that, compared with US patients, European patients had higher latest systolic BP levels (by 5.3-10.2 mm Hg across countries examined) and diastolic BP levels (by 1.9-5.3 mm Hg), a smaller likelihood of hypertension control (odds ratios, 0.27-0.50), and a smaller likelihood of medication increase for inadequately controlled hypertension (odds ratios, 0.29-0.65) (all P<.001). In addition, controlling for initial pretreatment BP level attenuated the differences in latest systolic and diastolic BP levels and the likelihood of hypertension control. CONCLUSION: Lower treatment thresholds and more intensive treatment contribute to better hypertension control in the United States compared with the western European countries studied.     

Hypertension, orthostatic hypotension, and the risk of falls in a community-dwelling elderly population: the maintenance of balance, independent living, intellect, and zest in the elderly of Boston study

OBJECTIVES: To investigate the relationships between uncontrolled and controlled hypertension, orthostatic hypotension (OH), and falls in participants of the Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly of Boston Study (N=722, mean age 78.1). DESIGN: Prospective population‐based study. SETTING: Community. PARTICIPANTS: Seven hundred twenty‐two adults aged 70 and older living within a 5‐mile radius of the study headquarters at Hebrew Rehabilitation Center in Boston. MEASUREMENTS: Blood pressure (BP) was measured at baseline in the supine position and after 1 and 3 minutes of standing. Systolic OH (SOH) and diastolic OH at 1 and 3 minutes were defined as a 20‐mmHg decline in systolic BP and a 10‐mmHg decline in diastolic BP upon standing. Hypertension was defined as BP of 140/90 mmHg or greater or receiving antihypertensive medications (controlled if BP<140/90 mmHg and uncontrolled if ≥140/90 mmHg). Falls data were prospectively collected using monthly calendars. Fallers were defined as those with at least two falls within 1 year of follow‐up. RESULTS: OH was highest in participants with uncontrolled hypertension; SOH at 1 minute was 19% in participants with uncontrolled hypertension, 5% in those with controlled hypertension, and 2% in those without hypertension (P≤.001)). Participants with SOH at 1 minute and uncontrolled hypertension were at greater risk of falls (hazard ratio=2.5, 95% confidence interval=1.3–5.0) than those with uncontrolled hypertension without OH. OH by itself was not associated with falls. CONCLUSION: Older adults with uncontrolled hypertension and SOH at 1 minute are at greater risk for falling within 1 year. Hypertension control, with or without OH, is not associated with greater risk of falls in older community‐dwelling adults.     

Strategies for improvement of awareness, treatment and control of hypertension: results of a panel discussion

High blood pressure (BP) is a major risk factor for coronary heart disease, heart failure, stroke, chronic kidney disease, end stage renal disease, and a variety of other clinically important outcomes. Results from the surveys described in this issue and elsewhere underscore a common finding that hypertension is both highly prevalent and insufficiently treated and controlled. Recognizing the differences in sampling and survey measurement techniques, the reported prevalence of hypertension (SBP/DBP >/=140/90 mmHg or treatment with antihypertensive medication) in adults exceeded 25% in all of the surveys reported in this issue. In Latvia, the prevalence of hypertension for 25-64-year-old adults in the general population was 46.1%. Control of hypertension with medication to an SBP/DBP <140/90 mmHg in the general population ranged from as low as 12% to a high of only 29%. Data from other parts of the world provide an equally distressing picture of what is (not) being accomplished in treatment and control of hypertension at the level of the general population. These data provide testimony to an urgent need for greater attention to the treatment and control of hypertension in populations around the world. This was the basis for a panel discussion at the International Society of Hypertension satellite conference The Epidemiology of Hypertension-Regional Differences in Treatment and Control. Panel participants included Drs P Whelton, S Sonkodi, DG Beevers, JG Fodor, H Elliot, R Cifkova, A Nissinen, A Javor, and there was active participation of other symposium attendees. The following summarizes key elements of the discussion and recommendations of the panel.     

Trends in Prevalence,Awareness, Treatment,and Control of Blood Pressure Recorded From 2004 to 2014 During World Hypertension Day in Italy

Estimates of blood pressure (BP) control in real life are not systematically collected in Italy. We evaluated trends in systolic/diastolic BP levels, as well as prevalence, awareness, treatment, and control rates of hypertension among adult individuals visiting open checkpoints during the 2004 to 2014 annual editions of World Hypertension Day. Hypertension was defined as BP level ≥140/90 mm Hg or use of antihypertensive medication, whereas BP control was defined as BP level <140/90 mm Hg. We included 10,051 individuals (53.2% female, age 56.2±16.8 years, body mass index 25.7±7.6 kg/m², systolic/diastolic BP 131.9±18.6/79.1±10.5 mm Hg). Hypertension prevalence and treatment were substantially unchanged, whereas awareness appears to increase over time. Controlled hypertension in diagnosed treated patients increased from 50.0% in 2004–2010 to 55.5% in 2011–2012 towards 57.6% in 2013–2014. This analysis provides real‐life snapshots of hypertension over the years in the occasion of World Hypertension Day, showing increased awareness and improved control rates among treated hypertensive patients attending open checkpoints during 2004 to 2014 in Italy.     

Prevalence of Masked Hypertension in Subjects Treated with Antihypertensive Drugs as Assessed by Morning versus Evening Home Blood Pressure Measurements: the J-HOME study

To investigate the relationship between morning and evening home blood pressure (BP) measurements to make a diagnosis of masked hypertension, we collected information on the characteristics of 3,303 essential hypertensive outpatients receiving antihypertensive medication in Japan using a physician, self-administered questionnaire. All patients were asked to measure their home BP once every morning and once every evening for two weeks. Morning and evening home BP values of each patient were defined as the average of all morning and all evening home BP values, respectively. The mean BP values of all study subjects were 142.8/80.6 mmHg for office BP, 139.8/81.8 mmHg for morning home BP, 133.7/76.9 mmHg for evening home BP, and 136.8/79.3 mmHg for the average of the morning and evening home BPs. Masked hypertension was defined as an office BP < 140/90 mmHg and a home BP > or = 135/85 mmHg. The prevalence of masked hypertension diagnosed using morning home BP (23.1%) was higher than that diagnosed by evening home BP (14.7%); the prevalence was 19.0% when diagnosed using the average of the morning and evening home BPs. Among the 1,386 patients with a normal office BP, the diagnosis of masked hypertension based on morning and evening home BP values differed in 28.8% of patients for systolic BP and 20.9% for diastolic BP (kappa coefficient = 0.43). The present study showed that the prevalence of masked hypertension was underestimated when the diagnosis of masked hypertension was made on the basis of evening home BP.     

Prevalence of Masked Hypertension in Subjects Treated with Antihypertensive Drugs as Assessed by Morning versus Evening Home Blood Pressure Measurements: The J-HOME Study

To investigate the relationship between morning and evening home blood pressure (BP) measurements to make a diagnosis of masked hypertension, we collected information on the characteristics of 3,303 essential hypertensive outpatients receiving antihypertensive medication in Japan using a physician, self-administered questionnaire. All patients were asked to measure their home BP once every morning and once every evening for two weeks. Morning and evening home BP values of each patient were defined as the average of all morning and all evening home BP values, respectively. The mean BP values of all study subjects were 142.8/80.6 mmHg for office BP, 139.8/81.8 mmHg for morning home BP, 133.7/76.9 mmHg for evening home BP, and 136.8/79.3 mmHg for the average of the morning and evening home BPs. Masked hypertension was defined as an office BP < 140/90 mmHg and a home BP ≥ 135/85 mmHg. The prevalence of masked hypertension diagnosed using morning home BP (23.1%) was higher than that diagnosed by evening home BP (14.7%); the prevalence was 19.0% when diagnosed using the average of the morning and evening home BPs. Among the 1,386 patients with a normal office BP, the diagnosis of masked hypertension based on morning and evening home BP values differed in 28.8% of patients for systolic BP and 20.9% for diastolic BP (kappa coefficient = 0.43). The present study showed that the prevalence of masked hypertension was underestimated when the diagnosis of masked hypertension was made on the basis of evening home BP.
