Samoa Hypertension Fact Sheet Summary

Core Content

The document presents a comprehensive overview of the burden of hypertension in Samoa, including prevalence rates, control status, and national response systems. It also outlines WHO recommendations for hypertension prevention and control.

Key Statistics (2013)

• Total Population: 190,712
• Adult Population (18+ years): Not explicitly stated, but derived from the STEPS survey data
• Hypertension Prevalence: 20% of the adult population have hypertension
• Uncontrolled Hypertension: 19.4 thousand people with hypertension do not have it under control

Hypertension Cascade by Age and Sex (2013)

• Males (18-64 years):

  • 22% of the population with hypertension are aware of their condition
  • 10.1% are under treatment
  • 4.9% have controlled blood pressure

• Females (18-64 years):

  • 27.9% of the population with hypertension are aware of their condition
  • 22% are under treatment
  • 6.9% have controlled blood pressure

National Systems Response (2019)

• Policy Availability: There is a policy in place to reduce population salt/sodium consumption
• Hypertension Medicines: Essential hypertension-related medicines are reported as "generally available"
• Blood Pressure Measurement: Blood pressure measurement is reported as "generally available" in primary health care facilities of the public sector

National Targets

• Hypertension: No specific national target is mentioned
• Salt Consumption: No specific national target is mentioned
• Raised Blood Pressure: No specific target is mentioned

WHO Recommendations for Hypertension Prevention and Control

1. Address Population Prevalence:

   • Reduce modifiable risk factors such as unhealthy diets (excessive salt, high saturated and trans fats, low fruit and vegetable intake), physical inactivity, tobacco and alcohol use, and overweight/obesity
   • Utilize WHO technical packages: MPOWER, ACTIVE, SHAKE, REPLACE, and HEARTS

2. Address Hypertension Control:

   • Improve and expand identification and treatment using evidence-based protocols
   • Intensify treatment for patients whose blood pressure is not controlled and ensure access to medicines
   • Track blood pressure control rates in clinical settings and measure population prevalence

Trends in Uncontrolled Hypertension Prevalence in Adults Aged 18+

• The prevalence of uncontrolled hypertension has increased over time
• Past Trends: Indicated by ● symbols
• Projected Linear Trends: Noted by — symbols
• Global Targets: Represented by ···○ symbols

Definitions

• Population with Hypertension: Individuals with SBP ≥ 140 mmHg, DBP ≥ 90 mmHg, or who have been diagnosed and treated for hypertension in the past two weeks
• Aware (Diagnosed): Individuals who meet the hypertension definition and have been told by a health worker they have hypertension
• Under Treatment: Individuals who meet the hypertension definition and are currently being treated with prescribed medication
• Controlled: Individuals with SBP < 140 mmHg, DBP < 90 mmHg, and who are aware and under treatment
