Obesity may affect the reproductive health of women and it is associated to the occurrence of stillbirths. Studies have shown a higher chance of fetal death among overweight and obese women. This study aimed to examine the relationship between maternal obesity and fetal death occurrence in a representative sample of the Brazilian population. Cross-sectional study which used secondary data from the National Demographic Health Survey of 2006 (PNDS/2006) studied 5.760 women of reproductive age (15-49 years) who participated in the survey along with their obstetric history since 2001. Obesity was determined using theanthropometric measures Body Mass Index, Waist Circumference and Waist-to-Height Ratio above the recommended standards. The fetal death occurrence was considered when the mother reported fetal loss after 20 weeks of gestation until delivery. For data analysis, PNDS/2006 databases were merged. Data analysis was performed using Statistical Software (STATA) version 12.0 and Statistical Package for the Social Sciences version 15.0. Features of complex survey design were taken into account using Statas survey suite of commands. Logistic regression models were estimated to evaluate the relationship between maternalobesity and fetal death occurrence (OR and 95% CI). Results shown different obesity markers positively associated to fetal death occurrence among women in reproductive age. The gain of each BMI unit would increase, approximately, 7.0% the chance of stillbirth, adjusted to maternal age, race and schooling. The same pattern was observed for the WC and WHR: they were presented as independent and positively associated with the fetal death occurrence. These results confirm the association between maternal obesity and fetal mortality. There areseveral potential biological mechanisms which explain this association corroborating to its plausibility. Thus, prevention of maternal obesity should constitute an axis of maternal and fetal health care.
