    Article - En anglais



    We report on the results of the Trestwell S-a-Day study increasing const of fruits and vegetables.


    Twenty-two worksites were randomly assigned to 3 groups : (1) a minimal intervention control group, (2) a worksite intervention, and (3) a worksite-plus-family intervention.

    The interventions used community-organizing strategies and were structured to target multiple levels of influence, following a socioecological model.

    Data were collected by self-administered employee surveys before and after the intervention ; the response rate was 87% (n=1359) at baseline and 76% (n=1306) at follow-up.

    A process tracking system was used to dociment intervention delivery.


    After control for worksite, gender, education, occupation, race/ethnicity, and living situation, total fruit and vegetable intake increased by 19% in the worksite-plus-family group, 7% in the worksite intervention group, and 0% in the control group (P=05).

    These changes reflect a one half-serving increase among workers in the worksite-plus-family group compared with the control group (P=018).


    The worksite-plus-family intervention was more successful in increasing fruit and vegetable consumption than was the worksite intervention.

    Worksite interventions involving family members appear to be a promising strategy for influencing workers'dietary habits.
