ABSTRACTIntroduction: The macrosomic state predisposes the newborn to perinatal morbimortality, it is defined with the weight variable. Preterm newborns don't reach that weight (4000 gr) even if they are macrosomic, excluding them from this risk group.
Objetive. To identify the prevalence of fetal macrosomia using weight and weeks of gestation as variables, associated with the form of delivery
Material and Methods: Observational, retrospective, cross-sectional, analytical design; 2100 newborns at Hospital General de Zona # 2 IMSS, Tabasco were included. Period from January 1st to December 31st 2004. Variables: gestational age, gender, weight and delivery way. Percentilar distribution and association measures were obtained
Results: The prevalence of macrosomia with the weight variable isolated was 5 x 100, stratifying by weeks of gestation and percentilar distribution the prevalence was 13.8 x 100 for females and 20.0 for males (x › P90). The greatest association macrosomia/cesarean section was found at 39 and 40 weeks, OR 2.16 (IC95 1.26, 3.72) y 1.85 (IC95 1.19, 2.88) respectively.
Conclusions: The prevalence of macrosomia in our study is similar to that of other populations. Using the percentilar distribution the prevalence is greater than using the weight variable alone, because newborns less than 37 weeks of gestation do not reach 4000 gr, even if they have macrosomic profile and probably they have the same perinatal risk factors. Newborns with a weight less than 4000 gr but over P90 of their gestational age must be a reason for study.
