Seasonality in sunny California’s fruit and vegetable consumption: Fact, fallacy or fiction

Population-based surveys designed to track dietary intake over time may not always be able to collect data during the exact same months each year the survey is fielded. The question arises whether or not there is a seasonal influence on the survey estimates that may obscure the true underlying trends, if any, across multiple years. This is the situation with the bi-annual California Dietary Practices Survey (CDPS) that has tracked fruit and vegetable intake since 1989. A separate calibration study was initiated in November 2000 to examine if seasonality exists for fruit and vegetable intake in the California population. This is also examined for White, African American and Latino groups and their corresponding low-income segments. ANOVA results will be presented from 8,543 telephone interviews collected from twenty-four independent monthly samples using CDPS protocols and methods. Monthly variation in total consumption and for fruit and vegetables separately will be shown for all groups. Despite apparently wide variation, especially for selected race/ethnic groups, even with large sample sizes, it will be shown that no obvious “seasons” could be detected. Findings for low-income Latinos will demonstrate analytical limitations in studies of this design. Issues related to the California food supply, economic factors and individual food choice behavior are discussed.
