Sri Lanka (Western Province) STEPS Survey 2003 Summary

Overview

The STEPS (Surveillance of Trends and Environmental Patterns) survey was conducted in the western province of Sri Lanka from July 2003 to October 2003. It aimed to assess chronic disease risk factors among adults aged 15-74 years. The survey consisted of two steps:

• Step 1: Collection of socio-demographic and behavioural data.
• Step 2: Collection of physical measurements.

A total of 3,000 adults participated, with an overall response rate of 100%.

Key Findings

• Tobacco use is relatively common, especially among males, with 32.6% of males smoking daily, compared to 16.6% of both sexes and 0.7% of females.
• Alcohol consumption is more prevalent among males than females, with 60.3% of males being current drinkers versus 11.5% of females.
• Low fruit and vegetable intake is widespread, with 96.9% of both sexes and 97.1% of males consuming less than 5 servings per day.
• Physical activity levels are generally low, with 15.6% of both sexes classified as having low activity levels.
• Males spend significantly more time in moderate physical activity (87 minutes/day) than females (15 minutes/day).
• BMI is within the normal range for the population, but obesity is present, with 4.3% of both sexes and 6.6% of females being obese.
• Waist circumference is slightly higher in males than in females, and blood pressure is generally within normal limits, though 6.9% of both sexes have raised blood pressure.

Conclusion

The STEPS survey highlights key chronic disease risk factors in the western province of Sri Lanka. It reveals that tobacco use, alcohol consumption, low fruit and vegetable intake, and low physical activity are significant public health concerns. While BMI is mostly normal, obesity and raised blood pressure are also notable issues, particularly among females. These findings provide valuable insights for health policy and intervention strategies targeting non-communicable diseases in the region.
