Note: B = unstandardised parameter estimate; CI, confidence interval; LL, lower limit; SE, standard error; UL, upper limit.

^(a)A positive parameter estimate indicates increasing values of the predictor are associated with greater increases in fruit and vegetable intake. Predictors are coded such that a higher value indicates greater levels of that predictor.

^(b)African Americans are coded 1 and non-African Americans are coded 0.

^(c)Women are coded 1 and men are coded 0.

^(d)Zero past weight loss attempts is the reference category.
