Plain English Summary

Background and study aims
Maternal overweight, infant feeding and early growth velocity are risk factors for obesity later in life. The first one thousand days are a window of opportunity to program health and disease. Exclusive breastfeeding may protect against obesity; however, it is not consistently practiced and obesity rates have been increasing worldwide. Overweight women have lower rates of breastfeeding. Breastfeeding counselling is a successful strategy to support breastfeeding in normal weight women, but there is a lack of evidence on its effectiveness in overweight women. The aim of this study is to test a new approach of exclusive breastfeeding counselling based on Carl Rogers’ Centered-Client Theory in overweight women, and to examine its effects on breastfeeding duration, infant growth velocity and maternal postpartum weight loss.

Who can participate?
Overweight pregnant women aged over 18 recruited in a Baby Friendly Hospital in Bogotá, Colombia

What does the study involve?
Participants are randomly allocated to the intervention (breastfeeding counseling) or control group (standard breastfeeding support).The intervention is exclusive breastfeeding counselling based on Rogers’ theory but adapted to support overweight women; it is performed during the last month of pregnancy, 24 hours after delivery and during early infancy. Exclusive breastfeeding duration, infant growth velocity and maternal weight loss are measured at the 1st, 3rd and 4th months after the birth.

What are the possible benefits and risks of participating?
The intervention may result in an increase in the initiation and duration of exclusive breastfeeding, allowing adequate infant growth velocity and maternal weight loss after delivery; it is hoped that the results of this trial will provide evidence to support public health policy on supporting breastfeeding in this vulnerable group of women. Benefits include a report of nutritional status at every appointment, economic support for transportation to the institution at every appointment and if the woman is allocated to intervention group she will receive breastfeeding counseling at three timepoints during the study. The study uses an intervention with minimum risk and represents a low health risk for the women related to providing blood and breast milk samples.

Where is the study run from?
Centro de Atención Prioritaria en Salud, Suba, Subred Norte (Columbia)

When is the study starting and how long is it expected to run for?

Scientific title

Effectiveness of a new approach for exclusive breastfeeding counselling on breastfeeding duration, infant growth velocity and postpartum weight loss in overweight women: a randomized controlled trial


Study hypothesis

Compared to standard management, the implementation of a new approach in EBF counselling to overweight woman will result in:
1. An increase in the prevalence of duration of BF and EBF from birth up to four months of age.
2. Slower growth velocity in infant weight for length from birth up to four months of age.
3. An increase in weight loss in the overweight woman after delivery to the fourth month postpartum.

Pregnant overweight and obese women


Participants are randomised to the intervention (breastfeeding counseling) or control group (standard breastfeeding support), partially blinded to the researcher. Randomization assignments will be prepared by a member of the team who has no contact with the study subjects, using randomized blocks. Assignments will be stored in sealed opaque envelopes. It will be not possible to blind researchers doing the intervention and collecting anthropometric and food intake data, but laboratory measurements will be blinded.

A new approach towards EBF counselling was designed based on Rogers’ client-centered theory. The women assigned to the intervention group will receive the intervention at three key timepoints:
1. Last month of gestation to prepare and promote the importance of early contact, BF initiation in the first postpartum hour, and to prepare the women to face difficulties in establishing BF
2. 24 hours postpartum to ensure that EBF is being established and to identify any difficulties the mother is experiencing
3. Early infancy (1st and 3rd months postpartum) to identify breastfeeding problems and empower the women to continue exclusive breastfeeding
The intervention will be conducted by a certified breastfeeding counsellor with listening skills, understanding the situation, analysing the environment and maternal BF problems in order to reach consensus solutions (woman and counsellor).

Intervention type



Drug names

Primary outcome measure

Measured at the 1st, 3rd and 4th months postpartum:
1. Duration of EBF and BF ascertained by asking the mother about infant feeding practices during the last 24 hours at birth and 4th month postpartum
2. Growth velocity in weight and length as the change in the indicators weight for length (W/L) and length for age (L/A) from birth up to 4 months
3. Maternal weight loss after delivery using the measurement of maternal weight at 24 hours as baseline and 4 months after delivery

Secondary outcome measures

Maternal serum levels of prolactin and prolactin concentration and macronutrients in the breast milk, measured at 1 and 4 months after delivery
