OBJECTIVE: To determine whether fruit and vegetable consumption among California adults significantly increased from 1997-2007.
DESIGN: Biennial telephone surveillance surveys of California adults’ dietary practices.
PARTICIPANTS: California adults (n = 9,105 total all 6 surveys).
INTERVENTION: Surveillance data reporting.
MAIN OUTCOME MEASURES: 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.
ANALYSIS: 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.
RESULTS: California adults significantly increased mean daily servings of fruits and vegetables from 3.8 servings in 1997 to 5.2 servings in 2007.
CONCLUSIONS AND IMPLICATIONS: 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
