Introduction: caffeine consumption is a world-wide extended habit, “mate” standing out as an important source of its ingestion in countries of the South cone. Objetives: to value caffeine ingestion during pregnancy, the contribution of the different sources of ingestion, and its relation to the weight at birth. Methodology and population: an observational analytical study of cross section was made. It included 240 puerperal women and their healthy newborns of 35 or more weeks. Results: the average maternal age was 24,96 (SD=6,01). 179 women (74,58%) were married or living with their partners. 67 of them (28,03%) were first pregnancies. The average number of controls during pregnancy was 7,31 (SD 3,32%), and 70 babies were born by caesarian (29,17%). The characteristics of the newborns reflect the referred criteria of inclusion: 35 weeks of gestation or more, vigorous, kept in the hospital with their mothers after birth. Throughout the pregnancy, the main source of caffeine was the ingestion of “mate”. The average of caffeine consumption was of 273,99 mg/day; “mate” consumption is the main source of caffeine with an average of 240 mg/day, contributing 85% of the daily intake of caffeine. A higher consumption of caffeine was observed in 77 pregnant women, 32% of the sample. The caffeine ingestion higher than 300 mg/day is associated to the birth of small babies for their gestational age. The ingestion of 100 mg of caffeine per day diminishes 38 g the weight at birth, independently of body-mass index or smoking habits. Conclusions: caffeine consumption is high in pregnant women of Uruguay, over 300 mg daily in 32% of the sample. “Mate” ingestion is the main source of caffeine in this population. The consumption of more than 300 mg a day is associated to higher risk of small newborns for their gestational age. In view of present scientific evidence, a suitable information scheme would have to be implemented to obtain a reduction on the consumption of “mate” and caffeine during gestation
