【 摘 要 】

Background This paper identifies factors that predict achievement of a low-fat diet among 242 California adults with low literacy skills, following their participation in the Stanford Nutrition Action Program (SNAP), a randomized classroom-based nutrition intervention trial (1993-1994). Methods. The intervention classes received a newly developed curriculum that focuses on reducing dietary fat intake (SNAP); the control classes received an existing general nutrition (GN) curriculum. Data were collected at baseline and 3 months postintervention, This hypothesis-generating analysis uses a signal detection method to identify mutually exclusive groups that met the goal of a low-fat diet, defined as <30% of calories from total fat, at 3 months postintervention. Results. Three mutually exclusive groups were identified. Twenty-three percent of Group 1, participants with high baseline dietary fat (>60 g) who received either the GN or the SNAP curriculum, met the postintervention goal of <30% of calories from total fat. Thirty-four percent of Group 2, participants with moderate baseline dietary fat (less than or equal to 60 g) who received the GN curriculum, were successful, Sixty percent of Group 3, participants with moderate baseline dietary fat who received the SNAP curriculum, were successful. Members of Group 3 also significantly increased their intake of vegetables, grains, and fiber. Conclusions. Within this population of adults with low literacy skills, a large proportion of those with moderate baseline dietary fat who participated in the SNAP classes met the postintervention criteria for a low-fat diet. A much smaller proportion of those with high baseline dietary fat were successful, suggesting that this group may benefit from different, more intensive, or longer-term interventions.
