Intervention group

EXPERIMENTAL

At 2-mo postpartum, women will start the 1-yr lifestyle intervention that will consist of 7 face-to-face individual sessions of 1-hr (at 2, 3, 4, 5, 6, 9, 12 mo postpartum and a follow-up at 18 mo). Metabolic and anthropometric measurements will be assessed at 2,6,12 and 18 mo postpartum. In addition, 7 individual sessions of 30 min between face-to-face sessions will be carried out on the phone. Benefits of exclusive breastfeeding, healthy eating and physical activity will be portrayed at each visit .

Behavioral: Lifestyle intervention

Active control lifestyle intervention

ACTIVE COMPARATOR

Women in the control group will come to the testing unit at 2, 6, 12 and 18 mo postpartum for metabolic and anthropometric measurements and at 3, 4, 5, 9 mo for weight measurements only. They will receive standard lifestyle recommendations in the form of written information at each visit.

Behavioral: Active control lifestyle intervention

Interventions

Women who are still breastfeeding at the first postpartum visit will be encouraged to pursue. References to local breastfeeding supporting groups will be done, if needed. The intervention will be conducted in order to reach recommendations for food servings and nutrient needs. Particular attention will be paid to increase fruits, vegetables, fish and whole grains intake, and decrease added sugars and high fat meat/dairy products. Women will be strongly encouraged to be active at least 150 min/week. They will be provided with targeted strategies for exercising, types of exercises and tips for including physical activity into the daily routine as well as fun exercises for the whole family.

Intervention group

Participants in the control group will receive standard lifestyle recommendations in the form of written information at each visit.
