Trend and factors associated with adverse birth weight in Uruguayan children between 2009 and 2015

Abstract

Objectives: to identify trendand factors associated with adverse birth weight. Methods: cross-sectional design. The analysis uses the 2009-2015 Uruguay Perinatal Computer Systemdata on 303,625 newborns. Results: the prevalence of macrosomia (> 3,999g) has increased from 7.0% to 8.4%. The prevalence of low birth weight (LBW) (< 2,500g) decreased, standing at 6.6% in the last year. The factors that determines more possibilities of LBW were preeclampsia (OR = 4.80; CI95%= 4.57-5.05), inadequate controls (OR = 2.29; CI95%= 2.20-2.39), shorter duration of pregnancy (OR = 2.52; CI95%= 2.50-2.55), previous hypertension (OR = 2.11; CI95%= 1.96-2.27), hypertensive disease of pregnancy (OR = 1.82; CI95%= 1.74-1.90), low prematernal maternal weight (OR = 1.65; CI95%= 1.58-1.74). Macrosomia was associated with type 1 diabetes (OR = 2.21; CI95%= 1.86-2.61), Type 2 or Gestational (OR = 1.78; CI95%= 1.70-1.87), obesity maternal (OR = 2.33; CI95%= 2.24-2.43) and longer gestation duration (OR = 2.62; CI95%= 2.53-2.72). Conclusions: the LBW decreases while the macrosomia increases. The health and nutritional status of women at the beginning of pregnancy, pathologies of the last trimester, smoking, shorter duration of pregnancy and inadequate controls are associated with BPN. Overweight, obesity and metabolic diseases determine macrosomia.

Avoidable deaths in the first 24 hours of life: health care reflexes

“…This high magnitude is related to the proximity of determination of these early deaths (32) . The condition of low birth weight (2,500 grams) is directly and indirectly related to the underlying pathologies in the gestational period (33) . In Uruguay, it was evidenced, in the historical series from 2009 to 2015, that arterial hypertension and hypertensive disorders in pregnancy, such as preeclampsia, increased the chances of low birth weight (33) .…”

Mortes evitáveis nas primeiras 24 horas de vida: reflexos da assistência à saúde

“…Essa alta magnitude está relacionada à proximidade de determinação dessas mortes precoces (32) . A condição de baixo peso ao nascer (2.500 gramas) está relacionada direta e indiretamente às patologias de base no período gestacional (33) . No Uruguai, foi evidenciado, na série histórica de 2009 a 2015, que a hipertensão arterial e os distúrbios hipertensivos na gravidez, como a pré-eclâmpsia, aumentaram as chances de baixo peso ao nascer (33) .…”
