We calculated rates from Behavioral Risk Factor Surveillance System data for Washington State (8), 2005 (inadequate fruit and vegetable consumption and inadequate physical activity) and 2006 (all other behaviors). We restricted all analyses to employed respondents aged 18 to 64 years; total sample sizes for this subgroup were 11,724 for 2005 and 11,356 for 2006. The analyses took the complex survey design and weighted sampling probabilities of the data into account and were performed using SUDAAN statistical software version 9.01 (RTI International, Research Triangle Park, North Carolina).
We defined outcome variables as follows: Inadequate fruit and vegetable consumption, consuming fewer than 5 servings of fruit and vegetables per day. Inadequate physical activity, not meeting guidelines for moderate physical activity (at least 5 sessions per week of at least 30 minutes each) or vigorous physical activity (at least 3 sessions per week of at least 20 minutes each). Overweight or obese, body mass index ≥25 kg/m2. Smoking, currently smokes. No breast cancer screening, women aged 40 to 64 years who have not had a mammogram in the past 2 years. No cervical cancer screening, women who have not had a Papanicolaou test in the past 3 years. No colorectal cancer screening, adults aged 50 to 64 years who have had neither a fecal occult blood test in the past year nor an endoscopy (flexible sigmoidoscopy or colonoscopy) in the past 10 years. No influenza vaccination, adults aged 50 to 64 years who have neither had a flu shot nor nasal flu spray vaccination in the past year.
