Table 3 Adjusted logistic regression results for prediction of adherence to dietary guidelines recommendations by vegetable preference and cooking self-efficacy scores among 4th grade children

From: Child assessments of vegetable preferences and cooking self-efficacy show predictive validity with targeted diet quality measures

  1. a Logistic regression adjusted for race/ethnicity and gender
  2. b Logistic regression adjusted for race/ethnicity, gender, and Body Mass Index z-score
  3. c Binary variable (yes/no) indicating status of scoring the maximum score for each HEI component: HEI Whole Fruit (5 point max), Total Vegetable (5 point max), Greens and Beans (5 points), and Empty Calories (20 points). Scoring the maximum score indicates conformance to the Dietary Guidelines for Americans
  4. d For all outcomes: Model 1 n = 98, Model 2 n = 90; possible scores ranged from 11 to 55. Higher scores indicated a greater cooking self-efficacy
  5. e For all outcomes: Model 1 n = 100, Model 2 n = 92; possible scores ranged from 8 to 40. Higher scores indicated a greater vegetable preference
  6. Bold indicates statistical significance (i.e. 95% confidence intervals that do not cross 1.00)
  7. OR = Odds Ratio, CI = Confidence Interval, HEI = Healthy Eating Index 2010
