Dietary outcomes in a Spanish-language randomized controlled diabetes prevention trial with pregnant Latinas

Abstract

Objectives: We evaluated the effectiveness of a community-based healthy lifestyle intervention in improving dietary behaviors of pregnant Latinas from 2004 to 2006 in Detroit, Michigan.

Methods: The 11-week, culturally tailored, Spanish-language Healthy Mothers on the Move (MOMs) intervention offered home visits, group classes, related activities, and social support from trained community health workers (CHWs) and peers. Dietary behaviors were measured by food frequency questionnaire. Linear mixed models estimated pre- and post-intervention changes, within and between MOMs intervention and minimal intervention (MI) groups.

Results: MOMs (n = 139) and MI (n = 139) participants had similar baseline characteristics and dietary intake. Post-intervention, MOMs participants showed significant improvement in all dietary behaviors, except fruit and fiber consumption. Compared with MI participants, MOMs participants had significantly decreased consumption of added sugar (P = .05), total fat (P < .05), saturated fat (P < .01), percentage of daily calories from saturated fat (P < .001), solid fats and added sugars (P < .001), and had increased vegetable consumption (P < .001). Their increase in fiber consumption (P < .05) was significant relative to MI participants' decrease in fiber intake.

Conclusions: We confirmed the hypothesis that a community-planned, CHW-led healthy lifestyle intervention could improve dietary behaviors of low-income Latina women during pregnancy.
