Dietary intake Sample Clauses

Dietary intake. We measured dietary intake using the Dietary Risk Assessment (DRA). The DRA is a 26-item food frequency questionnaire (FFQ) that measures usual intake of foods and beverages associated with cardiovascular disease risk.39,40 A single dietary intake score (ranging from 0-52) is obtained by summing the scores from four subsections: 1) nuts, oils, dressings, and spreads; 2) vegetables, fruit, whole grains, and beans; 3) drinks, desserts, snacks, eating out, and salt; and 4) fish, meat, poultry, dairy, and eggs. A higher score represents a healthier dietary pattern. Although the score can be dichotomized into “desirable” or “not desirable” we treated the score as continuous in all analyses as only five participants fell within the desirable category. The DRA was validated against the Xxxx Xxxxxxxxxx Cancer Research Center FFQ (FHCRC-FFQ) in a sample of low- income, midlife, southern, African American women. Correlations between total DRA score and three FHCRC-FFQ diet quality scores ranged from 0.57 to 0.60.39 BMI. We abstracted BMI from the electronic medical records where it is automatically calculated from the patient’s measured weight and height. We treated BMI as a continuous variable in all analyses. Control variables. The following control variables were included in adjusted analyses: age (continuous); education (less than high school; high school diploma or GED; some college or technical school; Associate’s degree or higher); employment status (full-time; part-time; unemployed, seeking employment; unemployed, not seeking employment); marital status (currently married; not married, living with a partner; never married; divorced, widowed, or separated); household size (continuous); annual income (less than $5,000; $5,000-$9,999; $10,000-$19,999; $20,000-$29,999; greater than $30,000); car ownership (yes; no); receipt of Supplemental Nutrition Assistance Program (SNAP) benefits (yes; no); smoking status (current smoker; former smoker; never smoker); and area-level median household income (continuous). In order to control for area-level median household income in all models, we created separate median household income variables for each of the four residential neighborhood and activity space environments. Using census block group-level median household income data, we created a continuous KDE surface representing the spatially varying median household income across the study area. We then extracted the average values for each polygon and set of activity spa...
