Mk. Hunt et al., IMPACT OF A WORKSITE CANCER PREVENTION PROGRAM ON EATING PATTERNS OF WORKERS, Journal of nutrition education, 25(5), 1993, pp. 236-244
Changes in the consumption of foods targeted by a cancer prevention in
tervention based on seven food-focused messages were measured in Treat
well, a randomized, controlled worksite nutrition intervention study a
imed at reducing dietary fat and increasing dietary fiber. Changes in
food intake of employees in five sites fully implementing the interven
tion were compared with those in eight control sites in order to asses
s the impact of the intervention on eating behavior. Food intake was m
easured using a semi-quantitative food frequency questionnaire (FFQ).
Some messages addressed consumption of one food, and others three or f
our foods in a category. Fourteen foods representing the seven message
s from the FFQ and summary questions were analyzed. The intervention m
essages were delivered to workers through activities such as classes o
n nutrition and weight management, taste tests, food demonstrations, a
nd point-of-purchase nutrition education programs. A total of 1762 wor
kers responded both to the baseline and the follow-up surveys. The rep
orted change values represent the average of the mean worksite values,
thereby assigning equal weight to each worksite, which served as the
unit of analysis. Workers in companies where the full intervention was
implemented decreased their use of margarine and butter as spreads (p
<0.01) and increased their intake of vegetables (p<0.02) significantly
more than did workers in control companies. There also was a suggesti
on of trends in the hypothesized direction for consumption of foods ta
rgeted by other eating pattern messages in intervention compared with
control companies.
