Non-communicable diseases (NCDs),such as heart disease, stroke, cancer, and diabetes, are the leading cause of death globally. These diseases are largely preventable, and their risk factors are often behavioral in nature, such as smoking, unhealthy diet, physical inactivity, and excessive alcohol consumption.

To monitor these risk factors and track progress towards reducing NCDs, the World Health Organization (WHO) established the Global Behavioral Risk Factor Surveillance (GBRFS) system in 2001. GBRFS is a standardized system for collecting data on key behavioral risk factors for NCDs from representative samples of adults in countries around the world.

Methodology

GBRFS is a cross-sectional survey that is conducted using a standardized questionnaire. The questionnaire includes questions on a range of behavioral risk factors, including:

* Tobacco use * Alcohol consumption * Physical activity * Diet * Fruit and vegetable consumption * Body weight and height

The survey is conducted in a representative sample of adults aged 18 years and older in each country. The sample size is typically between 1,000 and 5,000 adults.

Key Findings

GBRFS has collected data from over 1 million adults in over 100 countries. The findings from these surveys have provided valuable insights into the prevalence of behavioral risk factors for NCDs around the world.

Some of the key findings from GBRFS include:

* Smoking is the most common behavioral risk factor for NCDs, with over 1 billion adults worldwide smoking tobacco. * Unhealthy diet is another major risk factor for NCDs, with over 2 billion adults worldwide not consuming enough fruits and vegetables. * Physical inactivity is also a major risk factor for NCDs, with over 2 billion adults worldwide not getting enough physical activity. * Excessive alcohol consumption is a risk factor for NCDs, with over 2 billion adults worldwide drinking alcohol at harmful levels. * Obesity is a major risk factor for NCDs, with over 600 million adults worldwide obese.

Applications

The findings from GBRFS have been used to inform public health policy and programs around the world. For example, the findings have been used to:

* Develop and implement tobacco control policies * Promote healthy diets and physical activity * Reduce alcohol consumption * Prevent obesity

GBRFS has also been used to track progress towards reducing NCDs. The findings from GBRFS have shown that there has been some progress in reducing behavioral risk factors for NCDs in some countries. However, there is still much more work to be done.

GBRFS is a valuable tool for monitoring behavioral risk factors for NCDs and tracking progress towards reducing NCDs. The findings from GBRFS have been used to inform public health policy and programs around the world. GBRFS will continue to play an important role in the fight against NCDs in the years to come.
