What is the prevalence of hypertension in young adults and teenagers in the Philippines and does excessive caffeine intake from coffee and energy drinks contribute to its development?

Hypertension Prevalence in Filipino Youth

Hypertension affects approximately 23-28% of the general Filipino adult population, but specific prevalence data for teenagers and young adults in the Philippines is limited in the available evidence. 1, 2, 3

Prevalence Data in the Philippines

General Population Trends

• The prevalence of hypertension in the Philippines has steadily increased from 22% in 1993 to 25.15% in 2013, with the most recent data showing 28% prevalence in adults 1, 3
• Among older Filipinos (≥60 years), the prevalence reaches 69.1%, demonstrating age-related increases 4
• In rural areas specifically, hypertension prevalence was documented at 23% among residents ≥30 years old 2

Awareness and Control Issues

• Only 42-61.6% of hypertensive Filipinos are aware of their condition 1, 4
• Treatment rates are approximately 51.5-56%, with compliance at 57% 3, 4
• BP control is achieved in only 17-27% of hypertensive Filipinos, which is alarmingly low 1, 2, 3

Risk Factors in Filipino Youth

The following factors significantly increase hypertension risk in the Filipino population:

• Obesity and overweight status (body mass index ≥25) are strongly associated with hypertension 2
• Family history of hypertension 2
• Urban dwelling (associated with higher rates of hypertension, overweight, and obesity) 3
• Lower educational attainment correlates with more hypertension and smoking 3

Global Context for Young Adults and Teenagers

Pediatric and Adolescent Hypertension Prevalence

While Philippines-specific data for youth is lacking, international guidelines provide important context:

• The overall prevalence of confirmed clinical hypertension in children and adolescents globally is approximately 3.5% 5
• Elevated BP (formerly "prehypertension") affects an additional 2.2-3.5% of youth 5
• High BP is consistently greater in boys (15-19%) than girls (7-12%) when measured in screening settings 5
• Among youth with overweight and obesity, hypertension prevalence ranges from 3.8% to 24.8% 5

Rising Trends in Young Adults

• With rising rates of overweight and obesity globally, the prevalence of hypertension in young adults has increased substantially 5
• Young patients with isolated hypertension have high lifetime risk of cardiovascular disease 5
• In the CARDIA study of young adults followed over 18.8 years, adjusted hazard ratios for cardiovascular events were 1.67 for elevated BP, 1.75 for stage 1 hypertension, and 3.49 for stage 2 hypertension compared to normal BP 5

Caffeine Contribution from Coffee and Energy Drinks

The available clinical guidelines and research evidence do not establish excessive caffeine intake from coffee and energy drinks as a primary contributor to sustained hypertension in young adults and teenagers.

Why Caffeine is Not Emphasized in Guidelines

• The 2017 American Academy of Pediatrics guidelines for pediatric hypertension do not list caffeine or energy drink consumption as a risk factor requiring evaluation 5
• The 2021 ACC/AHA hypertension guidelines emphasize lifestyle factors but focus on diet quality (DASH diet), sodium reduction, physical activity, and weight management—not caffeine restriction 5
• The primary modifiable risk factors identified for hypertension prevention in youth are: maintaining normal BMI, consuming a DASH-type diet, avoiding excessive sodium consumption, and regular vigorous physical activity 5

Key Dietary Contributors Actually Identified

The evidence points to different dietary culprits:

• Only approximately 10% of youth aged 12-19 years eat adequate fruits and vegetables 5
• Only approximately 15% consume <1500 mg per day of sodium, which is a key dietary determinant of hypertension 5
• More than 80% of youth 12-19 years have a poor diet quality overall 5
• Obesity prevalence in Filipino populations shows 4.9% by BMI and 10.2-65.6% by waist-hip ratio, with urban dwellers more affected 3

Clinical Implications

While caffeine can cause acute, temporary BP elevations, the guidelines prioritize:

• Weight management as the single most important modifiable factor 5, 2
• Sodium restriction 5
• Overall diet quality improvement 5
• Increased physical activity 5

Common Pitfall

Do not focus on caffeine restriction while ignoring the established risk factors of obesity, high sodium intake, poor diet quality, and physical inactivity. The evidence strongly supports that these factors drive hypertension in youth, not coffee or energy drink consumption 5, 2, 3

Specific Concerns for the Philippines

Healthcare System Challenges

• Hospitalization from hypertensive complications can wipe out savings of middle-class families and is catastrophic for lower-income Filipinos 1
• The most prevalent complications in the Philippines are stroke (11.6%), ischemic heart disease (7.7%), chronic kidney disease (6.30%), and hypertensive retinopathy (2.30%) 1
• Monotherapy has been the treatment mode in more than 80% of Filipino patients, which likely explains the low BP control rates 1

Screening Recommendations

Given the high prevalence and poor control rates in the Philippines:

• All children ≥3 years should have BP measured at routine healthcare visits 5
• Children with obesity should have BP monitored at every clinical encounter 5
• For adolescents ≥13 years, use simplified thresholds: elevated BP is 120-129/<80 mmHg, stage 1 hypertension is 130-139/80-89 mmHg, and stage 2 hypertension is ≥140/90 mmHg 5
