American Samoa NCD STEPS Report Summary

1. Introduction

The survey assessed non-communicable disease (NCD) risk factors in American Samoa adults aged 25-64 years using the WHO STEPwise surveillance methodology to monitor trends and guide public health interventions.

2. Key Findings

Behavioral Measures

Tobacco Use: 29.9% current smokers (38.1% males vs 21.6% females)
Alcohol Consumption: 63.5% of population consumed alcohol, 49.6% of current drinkers engaged in binge drinking
Diet: Most individuals met none of the recommended dietary guidelines (mean fruit/vegetable servings=3.8/day), 86.7% consumed <5 servings combined
Physical Activity: Only 7.8% met physical activity guidelines, 62.2% were classified as physically inactive

Physical & Biochemical Measures

Obesity: 93.5% were overweight or obese (74.6% obese), mean BMI=34.9 kg/m²
Blood Pressure: 34.2% had hypertension, higher in males than females
Blood Glucose: 47.3% had diabetes (3% fasting hyperglycemia, others newly diagnosed)
Cholesterol: 23.4% had elevated cholesterol (>5.2 mmol/L)

Combined Risk Factors

0.4% had no risk factors
71.8% had ≥3 major risk factors
69.2% of 25-44 year olds had ≥3 risk factors

3. Conclusions

American Samoa faces a severe NCD epidemic with alarmingly high prevalence of major risk factors across multiple domains. Urgent population-level interventions are required to address tobacco use, alcohol consumption, poor diet, physical inactivity and obesity to prevent future disease burden.
