Insights

Systemic arterial hypertension affects nearly 80% of older adults in São Paulo, with over half experiencing uncontrolled blood pressure. Factors like nonwhite skin color and lack of insurance are linked to undiagnosed and uncontrolled hypertension in the elderly.

Area of Science:

  • Gerontology
  • Cardiovascular Disease Epidemiology
  • Public Health

Background:

  • Systemic arterial hypertension is the most common chronic noncommunicable disease in the elderly population.
  • Understanding hypertension prevalence and associated factors is crucial for public health interventions.

Purpose of the Study:

  • To estimate the prevalence of hypertension among individuals aged 60 years and older in São Paulo.
  • To analyze factors associated with diagnosed, undiagnosed, and uncontrolled hypertension in this demographic.

Main Methods:

  • Cross-sectional study utilizing data from the SABE (Health, Well-Being, and Aging) Survey conducted in 2010.
  • Probabilistic sample representative of the São Paulo city population aged ≥60 years.
  • Multinomial and logistic regression analyses to identify factors associated with hypertension diagnosis and control.

Main Results:

  • The prevalence of hypertension was 79.5% in the studied elderly population.
  • Hypertension remained uncontrolled in 51% of individuals diagnosed with the condition.
  • Undiagnosed hypertension was linked to nonwhite skin color, lack of insurance, and overweight; diagnosed hypertension was associated with older age, nonwhite skin color, lack of insurance, obesity, and presence of chronic diseases.
  • Uncontrolled hypertension was associated with widowhood, lack of insurance, and female gender.

Conclusions:

  • A high prevalence of hypertension exists in the elderly population of São Paulo.
  • Socioeconomic, demographic, and healthcare access factors significantly influence hypertension diagnosis and control in older adults.
  • Targeted interventions addressing these disparities are necessary to improve hypertension management in the elderly.

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension I: Introduction01:28

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
