Objective Abnormalities in birth weight and gestational age cause several adverse maternal and infant outcomes. Our study aims to determine the potential factors that affect birth weight and gestational age, and their association. MaterialsAndMethods We conducted this cross-sectional study of 4415 pregnant women in Tehran, Iran, from July 6-21, 2015. Joint multilevel multiple logistic regressio...

Background: Around one out of two mothers give births by cesarean section (CS) surgery in Iran and about half of this number is due to previous CS. Recently Health Sector Evolution (HSEP) program (started in April 2014) targets the high rate of CS in Iran. To assess the impact of the interventions, we emphasized that the First Birth Cesarean (FBC) proportion is one of the main indicators to ass...

Case-control studies have shown an association between low birth weight and risk for renal failure. The Medical Birth Registry of Norway, which comprises data on all births in Norway since 1967, and the Norwegian Renal Registry, which comprises data on all patients who have developed ESRD in Norway since 1980, were used to examine whether birth-related variables were associated with risk for ES...

BACKGROUND Birth interval is an important and potentially modifiable factor that is associated with child health. Whether an association exists with longer-term outcomes in adults is less well known. METHODS Using the 1982 Pelotas (Brazil) Birth Cohort Study, the association of birth interval with markers of cardiovascular health at 30 years of age was examined. Multivariable linear regressio...

the mean age at natural menopause and its determinants among shirazi women (southern iran) was calculated.  the data were obtained from a population- based cross-sectional study carried out in the year 2000.  interviews were carried out and observations made on 948 women who had incurred natural menopause. they were randomly chosen using postal zones housing sample framework of shiraz. mean±sd ...

despite reduction in infant mortality rate, neonatal mortality rate particularly during the first 24 hours of life is still high in developing countries. a cross-sectional study was performed to determine neonatal mortality prevalence during the first 24 hours of life (f24nm) and its probable risk factors. data collection were performed by a structured form containing maternal and neonatal char...

the main objective of this study was to estimate the genetic parameters for multi-trait evaluation of birth weight (bw), gestation length (gl) and calving difficulty (cd) in first-parity iranian holstein dairy cattle. the data included 29,950 calving records collected during 1995 to 2014 by the animal breeding and improvement center of iran. a threshold-linear sire-maternal grandsire model was ...
