To determine whether fruit and vegetable consumption among California adults significantly increased from 1997-2007.
Biennial telephone surveillance surveys of California adults' dietary practices.
California adults (n = 9,105 total all 6 surveys).
Surveillance data reporting.
Changes in fruit and vegetable consumption over time between 1997-2007, measured by mean servings and percentage of adults eating ≥ 5 servings on any given day.
Comparisons of subsets both within the same year and across years were made using t tests, chi-square, and Tukey Studentized Range tests at 5% procedure-wise error rate.
California adults significantly increased mean daily servings of fruits and vegetables from 3.8 servings in 1997 to 5.2 servings in 2007.
Since 1998, notable improvements in fruit and vegetable consumption have occurred to California populations, including the target audience groups of the Network for a Healthy California.
