Sommaire de l'article

There is a need for culturally relevant nutrition programs targeted to underserved cancer survivors.

Our aim was to examine the effect of a culturally based approach to dietary change on increasing fruit/vegetable (F/V) intake and decreasing fat intake among Hispanic breast cancer survivors.

Participants were randomized to Intervention and Control groups. Diet recalls, detailed interviews, fasting blood, and anthropometric measures were collected at baseline, 3, 6, and 12 months.

Hispanic women (n=70) with stage 0 to III breast cancer who completed adjuvant treatment and lived in New York City were randomized between April 2011 and March 2012.

The Intervention group (n=34) participated in ¡Cocinar Para Su Salud!, a culturally based nine-session (24 hours over 12 weeks) intervention including nutrition education, cooking classes, and food-shopping field trips. The Control group (n=36) received written dietary recommendations for breast cancer survivors.

Change at 6 months in daily F/V servings and percent calories from total fat were the main outcome measures.

Linear regression models adjusted for stratification factors and estimated marginal means were used to compare changes in diet from baseline to 3 and 6 months.

Baseline characteristics were the following: mean age 56.6 years (standard deviation 9.7 years), mean time since diagnosis 3.4 years (standard deviation 2.7 years), mean body mass index (calculated as kg/m²) 30.9 (standard deviation 6.0), 62.9% with annual household income ≤$15,000, mean daily servings of all F/V was 5.3 (targeted F/V 3.7 servings excluding legumes/juices/starchy vegetables/fried foods), and 27.7% of daily calories from fat. More than 60% in the Intervention group attended seven or more of nine classes, with overall study retention of 87% retention at 6 months. At month 6, the Intervention group compared with Control group reported an increase in mean servings of F/V from baseline (all F/V: +2.0 vs -0.1; P=0.005; targeted F/V: +2.7 vs +0.5; P=0.002) and a nonsignificant decrease in percent calories from fat (-7.5% vs -4.4%; P=0.23) and weight (-2.5 kg vs +3.8 kg; P=0.22).

¡Cocinar Para Su Salud! was effective at increasing short-term F/V intake in a diverse population of Hispanic breast cancer survivors.
