aThe Dietary Index is the sum of intake frequency estimates of 2 diet items (colas and non-cola soft drinks) divided by the sum of intake estimates of 4 items (fruit/berries, cooked vegetables, raw vegetables/salads, and fruit juice). There were 5 response alternatives for beverages and 6 for the food items (see Section 2). bnever smoker versus current or previous. c1–7 times per week versus less frequent. dLeisure time physical activity 0, <1, 1-2, 3 or more hours per week. Unstandardized (B) and standardized (β) regression coefficients are shown. |
