This pilot study examined the effectiveness of a 4-month clinic-based dietary intervention emphasizing the intake of deep yellow and dark green vegetables versus usual care on improving diet quality in postpartum women. The intervention group (n = 31) received 1 face-to-face nutrition education session with a registered dietitian, 2 follow-up phone calls, and 3 pamphlets distributed by mail. The usual care group (n = 25) received handouts with guidelines on healthy eating. Dietary outcomes were assessed from 3-day food recalls and evaluated using paired and independent t tests. Intervention women exhibited a significant increase in total vegetable intake (P < .001) and in dark green and deep yellow vegetables (P < .001). In comparison, the control group increased the intake of total vegetables (P < .001), but did not increase the consumption of dark green and deep yellow vegetables. When comparing the change in intake between study groups for both types of vegetables, the difference was not significant. Furthermore, 61% of the intervention women met the goals for total vegetable intake compared with 12% for the usual care group (P < .001). The intervention group also had a greater percentage of women (25.8%) that met the goal for deep yellow and dark green vegetable intake when compared with the usual care group (8%; P < .08). These results suggest that postpartum women are receptive to nutrition education and that nutrition education can influence vegetable intake.

Objective: To evaluate the effectiveness of a dietary intervention to increase target vegetable intake in overweight, postpartum mothers; and their children. Methods: Overweight mothers attending their six-week postpartum follow-up visit and their infants (n = 104 pairs) were randomized to intervention or usual care groups during the time period 2008-2011. Mothers received four 60 minute education sessions with a nutrition professional and eight monthly follow-up phone calls. Counseling began at the obstetrician office and continued at the regularly scheduled pediatric visits. The primary study outcome was the change in maternal target vegetable intake. Secondary outcomes included child target vegetable intake and whether child vegetable intake was modified by exposure to breastfeeding. Mother/child energy intake and weight indices were also assessed. Outcomes were measured at baseline (6-weeks postpartum), 6, 12 (post-intervention), and 18 (follow-up) months. Mixed-effects models were used to estimate the impact of the dietary intervention on study outcomes relative to usual care. Results: Mothers randomized to the intervention had greater consumption of target vegetables at 6, 12 and 18 months (P < 0.01, P < 0.01 and P = 0.03, respectively). There were no differences between groups in maternal energy intake, body mass index, or child target vegetable or energy intake. The child's target vegetable intake at 12 months was related to the mother's intake at 6 months (P = 0.03), however, this relationship was not modified by exposure to breastfeeding. Conclusion: A dietary intervention targeting the diet of the mother/child dyad resulted in improved maternal vegetable intake.
