Cameroon STEPS Survey 2003 Summary

The Cameroon STEPS Survey was conducted from July 2003 to October 2003 to assess chronic disease risk factors. It included Steps 1, 2, and 3: Step 1 gathered socio-demographic and behavioral data, Step 2 collected physical measurements like height, weight, and blood pressure, and Step 3 measured biochemical indicators such as blood glucose levels. The survey used a population-based approach with a cluster sample design for adults aged 15-64+, involving 9,720 participants (89.8% response rate).

Key findings from Step 1 behavioral data show high smoking rates among males (12.7% current smokers, including 9.7% daily smokers starting around age 21), with lower rates in females. Alcohol consumption was prevalent, with 11.8% of males drinking 4 or more days per week, and binge drinking noted in 9% of males. Fruit and vegetable intake averaged less than five servings per day, and physical activity was low across genders, with about half classified as low activity (<600 MET-minutes/week).

Step 2 physical measurements indicate widespread overweight and obesity, particularly in females (50.5% overweight, 21.4% obese), with mean BMI of 25.1 kg/m² and high prevalence of hypertension (17.3% and 8.2% based on different criteria). Step 3 biochemical results show elevated blood glucose levels, with impaired fasting glycaemia in 10.6% (males 7.9%) and raised blood glucose in 13.9% (males 15.2%).

The survey highlighted common risk factors, including smoking, low fruit and vegetable intake, sedentary behavior, overweight/obesity, and hypertension. For instance, a high percentage of adults had at least three risk factors, especially in younger age groups (aged 25-44 and 25-64).

This summary captures the main chronic disease risk factors identified, emphasizing the need for public health interventions in Cameroon.
