Reported are the results of a randomized controlled trial to assess the eff
ectiveness of the WHO/UNICEF 40-hour course "Breastfeeding counselling: a t
raining course". The course was conducted in a maternity hospital which pro
vides care to a low-income population in a metropolitan area in Sao Paulo,
Brazil, Health workers from 60 health units were randomly assigned to be ei
ther participants (20) or controls (40), and their breastfeeding knowledge
and skills were assessed before and immediately after the course, as well a
s 3 months later. Immediately after the course the participants' knowledge
of breastfeeding had increased significantly compared to controls. Both the
ir clinical and counselling skills also improved significantly. When assess
ed 3 months later, the scores remained high with only a small decrease.
The implementation of the course was also evaluated. The methods used were
participatory observation, key interviews and focus group discussion. In th
e 33 sessions of the course, the average score was 8.43 out of 10. Scores w
ere highest for content and methodology of the theory sessions, and lowest
for "use of time", "clinical management of lactation", and "discussion of c
linical practice".
"Breastfeeding counselling: a training course" therefore effectively increa
ses health workers' knowledge and their clinical and counselling skills for
the support of breastfeeding. The course can be conducted adequately using
the material and methodology proposed, but could be more satisfactory if t
he time allocated to exercises and clinical practice sessions were increase
d.
