Introduction: During the past decade, the proportion of older than 35 years women giving birth has significantly increased. There are numerous COMPLICATIONS of pregnancy-affecting both the mother and fetus among these women. Older women with medical conditions are at greater risk of postpartum COMPLICATIONS, especially thrombosis, pulmonary edema and heart failure.Materials and Methods: This retrospective cross-sectional case control study was performed over a period of one year in Qaem and Hazrat Zeynab Hospital, affiliated to Mashhad University of Medical Sciences. One hundred and seventy pregnant women aged 35 (case group) and 170 women with aged 20-30 years (control group) were matched. The personal and medical information and pregnancy outcome was filled out in a questionnaire for all patients. Appropriate statistical analysis including student t-test and Chi-Square were performed using SPSS version 11.5.Results: The mean age of case group was 37±2.9 and the control group was 25.3±3.1. The results showed that frequency of poor pregnancy outcome and COMPLICATIONS were higher in the case group. These differences were statistically significant in cesarean section rate, abortion prevalence, third trimester bleeding, need to transfusion, gestational diabetes mellitus, anemia and post-partum problems. The prevalence of neonatal COMPLICATIONS such as preterm labor, one-minute apgar scores of<3, macrosomia and still birth in the study group were more than the control group. MATERNAL age was not an independent risk factor in neonatal problem; it means that mothers with advances ages probably have the same neonatal outcome.Conclusion: According to this study, women should realistically appraise the risks of pregnancy after 35 that are increasingly common in our society. Improved obstetrical care has made advanced MATERNAL age compatible with successful pregnancy for the great majority of such women.

Background and Objective: Overweight, obesity and ethnicity are effective factors on pregnancy COMPLICATIONS. This study was conducted to determine the relationship between third tri-mester body mass index (BMI) with MATERNAL and neonatal COMPLICATIONS.Methods: This descriptive analytic study was conducted on 551 pregnant women in third tri-mester with Fars, Sistani and Turkman ethnicities in Sayad Shirazi teaching hospital in Gorgan, north of Iran during 2012. BMI calculated at the time of labor admission and the subjects categorized into three groups of normal / underweight, overweight and obese.Results: The mean of MATERNAL age among Fars, Sistani and Turkman ethnic groups were 26.5±5.5, 24.6±5.3 and 26.2±5.2 years, respectively. The mean of gestational age among Fars, Sistani and Turkman ethnic groups were 38.4±2.3, 38.6±2.3 and 37.4±3.2 weeks, respectively. A significant relationship was found between BMI and cesarean section and labor dystocia in Fars and Sistani ethnic groups, respectively (P<0.05), while no relationship was found between BMI and neonatal COMPLICATIONS.Conclusion: Overweight and obesity in Fars ethnicity are at risk of cesarean section and those with Sistani ethnicity are at risk of labor dystocia.

Background & Objective: Although the safety of cesarean sections has increased, there are still considerations, especially for women with a history of repeated cesarean sections. This study was conducted with the aim of investigating MATERNAL and neonatal outcomes in candidates for cesarean sections due to repeat cesarean sections according to the number of previous cesarean sections.Materials & Methods: This prospective descriptive study was conducted from April 2020 to June 2022 at Taleghani Hospital. All candidates for cesarean sections due to repeated cesarean sections were included in the study. According to the number of previous cesarean sections, they were divided into three groups. Statistical analysis was performed with Kruskal-Wallis, Chi-squared and Fisher’s exact tests. A P value < 0.05 indicated statistical significance.Results: A total of 345 women were included in the study. The results of this study showed that these three groups were significantly different in terms of duration of surgery (P<0.001), abnormal placental adhesion (0.012), and the presence of intraperitoneal adhesions (P<0.001), but there was not a significant difference in terms of other MATERNAL and neonatal outcomes (P<0.05).Conclusion: The results of this study showed that an increase in the number of previous cesarean sections does not increase most MATERNAL and neonatal COMPLICATIONS during a current cesarean section. Of course, it should be noted that the number of women with a history of three or more previous cesarean sections was small in this study, and for this reason, more studies are needed.
