Overall Nutritional Habit Score (0–14), Mean (SD)^{†} | 6.01 | (2.73) |

* The sample N includes all those who answered at least 5 of the 7 nutritional habit questions. The sample size for individual items varies from 1642 to 1708 because of missing data.

† Scored as the sum of the 7 items, each 0 to 2, with higher scores reflecting poorer nutritional habits. If 2 or fewer items were missing, values for missing items were imputed as the mean of the nonmissing items. Cronbach’s α for the score is 0.558, and item total correlation range from 0.069 (lean protein consumption) to 0.407 (high-fat snack consumption). The median value is 6, and the most common (modal) value is 7.0, indicating very little skew. Visual inspection of the distribution and Q-Q plot indicate that the assumption of a normal distribution (and the application of parametric statistical tests) is valid.
