Cape Verde STEPS Survey 2007 Summary

Survey Overview

• Implementation period: November to December 2007.
• Steps conducted: Step 1 (collected socio-demographic and behavioral data), Step 2 (measured physical parameters including height, weight, and blood pressure), and Step 3 (assessed biochemical indicators like blood glucose and cholesterol).
• Target population: Adults aged 25-64 years, with a cluster sample design ensuring representativeness and total participants: 1,762.

Key Findings

Step 1: Behavioral Risk Factors

• Tobacco use: 9.9% of all adults smoke tobacco; daily smoking is reported by 8.1%; average start age for smoking is 19.5 years; 89.0% use manufactured cigarettes; average daily consumption is 9.5 cigarettes.
• Alcohol consumption: 46.9% are abstainers; 40.3% are current drinkers; 44.1% engage in binge drinking (high-intensity consumption).
• Fruit and vegetable intake: Mean fruit servings per day: 1.4; mean vegetable servings per day: 1.4; 86.1% consume less than 5 combined servings on average.
• Physical activity: 19.4% have low activity levels (<600 MET-min/week); 60.3% have high activity levels (≥3000 MET-min/week); median daily activity time is 162.9 minutes.

Step 2: Physical Measurements

• Body metrics: Mean BMI is 24.3; 36.9% are overweight (BMI ≥25); 10.5% are obese (BMI ≥30); average waist circumference is 83.5 cm.
• Blood pressure: Mean systolic BP is 133.3 mmHg, mean diastolic BP is 79.8 mmHg; 38.7% have raised BP (SBP ≥140 or DBP ≥90 or on medication).

Step 3: Biochemical Measurements

• Blood glucose: Mean fasting glucose is 5.4 mmol/L; 25.6% have impaired fasting glycaemia; 12.7% have raised blood glucose.
• Cholesterol: Mean total cholesterol is 4.2 mmol/L; 13.0% have raised total cholesterol (≥5.0 mmol/L or ≥190 mg/dl).

Summary of Combined Risk Factors

• Identified risk factors: current daily smoking, BMI ≥25 kg/m², fruit and vegetable intake less than 5 servings/day, raised blood pressure, low physical activity.
• Percentage with none of these risk factors: approximately 5% of all adults.
• Percentage with at least three risk factors: 19.6% across all ages; significantly higher in older age groups (e.g., 41.8% aged 45-64 years).
