The NAURU STEPS Survey (July-September 2004) was a population-based study involving 2081 adults aged 15-64, with an 82% response rate. Key findings across the four steps are as follows:

• Tobacco Use: Approximately 48.2% of adults smoke daily tobacco, with an average start age of 15.9 years and high daily consumption, particularly manufactured cigarettes (99%).

• Alcohol Consumption: A significant portion abstains from alcohol (53.8%), but among current drinkers, some exhibit high-risk behaviors, such as 29.8% of men consuming 5 or more drinks on any day.

• Fruit and Vegetable Intake: Average consumption is low, with only about 0.9 servings of fruit and vegetables per day for most adults, meaning 96.9% consumed less than the recommended 5 servings daily.

• Physical Activity: Activity levels are predominantly low, with 51.6% meeting less than 600 MET-minutes/week, reflecting minimal high-intensity activity (2.2% meeting high levels).

• Physical Measurements: The average BMI is high (32.1), with 82.2% classified as overweight or obese and 58.1% as obese. Also, 17-23% have elevated blood pressure (SBP ≥140 or DBP ≥90), comparable among adults after accounting for medication.

• Biochemical Measurements: About 16% have elevated fasting blood glucose (>7.0 mmol/L), and overall, 17.9% have high total cholesterol (≥5.2 mmol/L). Some participants have multiple severely elevated biochemical indicators.

Combined risk factors show that the majority of the adult population (around 85%) has at least three of the following: current smoking, daily fruit/vegetable intake below five servings, low activity levels, or obesity. Risk is particularly high among older adults (aged 45-64 for 85% risk, and earlier in life for 77-80% risk), with very few individuals (less than 1%) having low or no risk factors overall. This indicates a high prevalence of chronic disease risk factors across key behaviors, measurements, and biochemistry.
