California adults increase fruit and vegetable consumption from 1997-2007.

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.
