The Impact of Lifestyle Behavior on Hypertension Awareness, Treatment, and Control in a Southeastern Population

Evaluation of Hypertension Prevention and Control Programs in Lima, Peru

Objectives

The Korea International Cooperation Agency (KOICA) established 4 health centers to provide hypertension screening and a health support program in a deprived urban area of Lima, Peru. This case report provides a mid-term evaluation of the KOICA’s hypertension prevention and control programs.

Methods

A follow up study was performed on 663 residents who were diagnosed with prehypertension or hypertension (Stage 1 and 2) in the 4 KOICA health centers. Patients participated in programs designed to prevent and control hypertension through education sessions over the course of 6 months. Using simple descriptive statistics and computer simulations, we evaluated the effect of hypertension prevention and control programs on the participants.

Results

The KOICA health programs appeared to significantly contribute to lowering the blood pressure (BP) of the participants. The total number of participants with normal BP increased from none to 109. Overall, the female and younger patients responded better to the KOICA programs than the male and older participants. In addition, the average systolic BP, diastolic BP, and body mass index of all participants was significantly reduced.

Conclusion

The KOICA programs were effective at lowering blood pressure, particularly amongst the prehypertension group than the Stage 1 and 2 hypertension groups. This suggests that providing an extensive screening service for adults with prehypertension will help control hypertension in the early stages.

Management of high blood pressure in Blacks: an update of the International Society on Hypertension in Blacks consensus statement

Since the first International Society on Hypertension in Blacks consensus statement on the "Management of High Blood Pressure in African American" in 2003, data from additional clinical trials have become available. We reviewed hypertension and cardiovascular disease prevention and treatment guidelines, pharmacological hypertension clinical end point trials, and blood pressure-lowering trials in blacks. Selected trials without significant black representation were considered. In this update, blacks with hypertension are divided into 2 risk strata, primary prevention, where elevated blood pressure without target organ damage, preclinical cardiovascular disease, or overt cardiovascular disease for whom blood pressure consistently <135/85 mm Hg is recommended, and secondary prevention, where elevated blood pressure with target organ damage, preclinical cardiovascular disease, and/or a history of cardiovascular disease, for whom blood pressure consistently <130/80 mm Hg is recommended. If blood pressure is ≤10 mm Hg above target levels, monotherapy with a diuretic or calcium channel blocker is preferred. When blood pressure is >15/10 mm Hg above target, 2-drug therapy is recommended, with either a calcium channel blocker plus a renin-angiotensin system blocker or, alternatively, in edematous and/or volume-overload states, with a thiazide diuretic plus a renin-angiotensin system blocker. Effective multidrug therapeutic combinations through 4 drugs are described. Comprehensive lifestyle modifications should be initiated in blacks when blood pressure is ≥115/75 mm Hg. The updated International Society on Hypertension in Blacks consensus statement on hypertension management in blacks lowers the minimum target blood pressure level for the lowest-risk blacks, emphasizes effective multidrug regimens, and de-emphasizes monotherapy.

Survey of prevalence, awareness, treatment, and control of hypertension among Chinese governmental and institutional employees in Beijing

BACKGROUND

Few studies have been done on the effects that awareness, treatment, and control have on hypertension among governmental and institutional employees.

HYPOTHESIS

The aim of this study was to explore prevalence, awareness, treatment and control of hypertension among governmental and institutional employees.

METHODS

A total of 80 governmental organizations and institutions were selected with a 2-stage clustering sampling method in Beijing and all employees in the selected institutions were considered our study subjects. The survey questionnaires included demographic characteristics; medical, personal, and family health history; lifestyle information; and sources of blood pressure knowledge.

RESULTS

The ages of 30 682 subjects ranged from 18 to 65 years and averaged 40.3 +/- 11.4 years. The proportion of males was 54.4% (16 702 subjects). A total of 9216 subjects were diagnosed hypertensive and the prevalence rate was 30.0%. Among hypertensive patients, 5399 subjects were aware of being hypertensive and the awareness rate was 58.6%. Although 51.7% of hypertensive subjects were taking antihypertensive medications, only 2371 subjects had their blood pressure under control (<140/90 mm Hg) and the control rate was 25.7%. Only 4915 subjects (16.0%) monitored their own blood pressure regularly. Health publications (50.6%) and families/friends (49.1%) were the main sources of hypertension knowledge. Female hypertensive subjects have more effectively controlled blood pressure than their male counterparts. Subjects with a bachelor's degree or higher had a lower awareness rate and treatment rate, but a higher control rate.

CONCLUSIONS

The percentage of hypertensive subjects who are aware, treated, and controlled are unacceptably low among Chinese governmental and institutional employees. Regular medical check-ups and measuring of blood pressure are necessary to improve awareness, treatment, and control of hypertension.

Differences in prevalence, awareness, treatment and control of hypertension between developing and developed countries

Objective To systematically review quantitative differences in the prevalence, awareness, treatment and control of hypertension between developed and developing countries over the past 6 years. Methods We searched Medline [prevalence AND awareness AND treatment AND control AND (hypertension OR high blood pressure)] for population-based surveys. Prevalence, awareness, treatment and control of hypertension were compared between men and women, and between developing and developed countries, adjusting for age. The proportions of awareness, treatment and control were defined relative to the total number of hypertensive patients. Results We identified 248 articles, of which 204 did not fulfill inclusion criteria. The remaining articles reported data from 35 countries. Among men, the mean prevalence, awareness, treatment and control of hypertension were 32.2, 40.6, 29.2 and 9.8%, respectively, in developing countries and 40.8, 49.2, 29.1 and 10.8%, respectively, in developed countries. Among women, the mean prevalence, awareness, treatment and control of hypertension were 30.5, 52.7, 40.5, and 16.2%, respectively, in developing countries and 33.0, 61.7, 40.6 and 17.3%, respectively, in developed countries. After adjusting for age, the prevalence of hypertension among men was lower in developing than in developed countries (difference, S6.5%; 95% confidence interval, S11.3 to S1.8%). Conclusion There were no significant differences in mean prevalence, awareness, treatment and control of hypertension between developed and developing countries, except for a higher prevalence among men in developed countries. The prevalence, awareness, treatment and control of hypertension in developing countries are coming closer to those in developed countries.

Effects of hypertension and hypercholesterolemia on cognitive functioning in patients with alzheimer disease

This study investigated the relationship between the vascular comorbidities (VCs) of hypertension and hypercholesterolemia and the cognitive phenotype of Alzheimer disease (AD). Seventy-four AD patients underwent objective measurement of blood pressure and serum cholesterol levels, and they received a detailed neuropsychologic evaluation examining attention, memory, language, visuomotor/visuospatial skills, and executive functioning. Multiple regression analyses controlling for demographic variables, overall cognitive status, and the presence of diabetes/cardiac disease indicated that an increase in the number of VCs, but not their severity, was associated with poorer verbal and visual recall, visuoconstructive and spatial analysis, verbal reasoning, and set shifting. The findings demonstrate that VCs are associated with specific aspects of cognitive functioning in AD patients. The mechanisms likely involve the effects of VCs on cerebrovascular disease including white matter disruption. The results highlight the importance of controlling these risk factors in patients who carry the diagnosis of AD.

Racial/ethnic variation in hypertension-related lifestyle behaviours among US women with self-reported hypertension

Healthy lifestyles such as regular physical activity, frequent consumption of fruits and vegetables, weight control/weight loss and limited alcohol consumption are effective and recommended in hypertension control. Using data collected from a total of 131 788 female participants (aged > or = 18 years) of the 2003 Behavioral Risk Factor Surveillance System, we examined the racial/ethnic disparities in hypertension-related lifestyle behaviours in 36 770 US women with self-reported hypertension from five races/ethnicities (non-Hispanic white (29 237), non-Hispanic black (4288), Asian (445), American Indian/Alaska native (553) and Hispanic (2247)). The prevalence of hypertension varied by race/ethnicity, with the highest seen in non-Hispanic black population (36.9 versus 20.2-26.8% in other racial/ethnic groups). Of all hypertensive women, using non-Hispanic white women as the referent, we found that non-Hispanic black (adjusted odds ratio (AOR): 0.65; 95% confidence interval (CI): 0.55-0.77), American Indian/Alaska native (AOR: 0.72; 95% CI: 0.52-1.00) and Hispanic women (AOR: 0.70; 95% CI: 0.57-0.86) were significantly less likely to engage in physical activity at recommended levels; non-Hispanic black women were more likely to consume > or = 8 servings per day of fruits and vegetables (AOR: 1.70; 95% CI: 1.24-2.34), and less likely to report losing weight (AOR: 0.61; 95% CI: 0.53-0.71). In addition, Hispanic hypertensive women were significantly more likely than non-Hispanic white women to receive weight-loss advice (AOR: 1.97; 95% CI: 1.60-2.44). In contrast, non-Hispanic white women were significantly more likely than those from other races/ethnicities to consume alcoholic beverages or engage in binge drinking. Our results demonstrate that race/ethnicity is an independent predictor of lifestyle behaviours related to hypertension control among American women with hypertension.

Impact of World Hypertension Day

It is estimated that nearly one billion people are affected by hypertension worldwide, and this figure is predicted to increase to 1.5 billion by 2025. Nearly one-half of this population are unaware of their condition. Hypertension is the primary risk factor for heart disease and stroke. World Hypertension Day (WHD) has been an initiative of the World Hypertension League to raise hypertension awareness. In the past two years, many countries have taken an active part in promoting awareness through a number of initiatives in their respective countries. In Canada, WHD was a resounding success in 2005 and 2006, and major plans are underway for WHD 2007. The success of the Canadian WHD depends mainly on the partnership and shared values of all stakeholders, including professional societies, nongovernment organizations, government agencies and industry. Although it is too early to assess the impact of hypertension, it is evident that the countries involved are taking hypertension in the population seriously and are moving in the right direction. If the momentum continues, a drastic reduction in the prevalence of worldwide hypertension can be anticipated.
