STEPS Survey Summary: Chronic Disease Risk Factors in Algeria

Core Content

The STEPS (STEPS Survey for Chronic Disease Risk Factors) survey in Algeria was conducted between September and October 2003. It was a population-based study targeting adults aged 25–64 years, aiming to assess key risk factors for chronic diseases. The survey was structured into three steps:

Step 1: Collection of socio-demographic and behavioral data, including tobacco use, alcohol consumption, fruit and vegetable intake, and physical activity.
Step 2: Physical measurements such as body mass index (BMI), waist circumference, and blood pressure.
Step 3: Biochemical measurements, including fasting blood glucose and total blood cholesterol levels.

A stratified cluster sampling design was employed to ensure the data was representative of the target population. A total of 4,102 adults participated in the survey.

Key Information

The survey highlights that tobacco use is predominantly male, with only 0.4% of females currently smoking.
Alcohol consumption is almost non-existent among the population, with 99.0% of adults being abstainers.
Fruit and vegetable intake is low, with over 87% of adults consuming less than 5 servings per day.
Physical activity levels are generally low, with over 40% of adults classified as having low activity levels.
Overweight and obesity are significant issues, with nearly half of the population (46.7%) being overweight and 16.6% obese.
Raised blood pressure is common, affecting 29.3% of adults.
Impaired fasting glucose and high cholesterol levels are also prevalent, indicating a high risk of metabolic disorders.
