Background The purpose of the present study was to evaluate obstetric, maternal, and neonatal outcomes in COVID-19 compared to healthy pregnant women in Iran. Results A case-control study was conducted on 55 COVID-19 as the case and 55 matched control pregnant women in Hormozgan, Iran. Patients were considered to be cases if they had a positive COVID-19 test plus a positive chest X-ray result. Our measures were COVID-19 symptoms, including laboratory evaluations, clinical symptoms, and maternal and neonatal outcomes. The most prevalent symptoms related to COVID-19 were fever (69.09%) and cough (58.18%). Less common symptoms included fatigue, diarrhea, shortness of breath, sore throat, and myalgia. Hydroxychloroquine/chloroquine (58.18%) and antibiotic therapy (45.45%) were the most prevalent management in COVID-19 patients. Based on our findings, maternal and obstetric outcomes—neonatal in case groups—such as mode of delivery, premature rupture of membrane, postpartum hemorrhage, perineal resection rate, neonates’ birth weight, Apgar score, and neonatal asphyxia rate were similar to pregnant women without COVID-19. We observed a higher incidence rate of premature delivery in COVID-19 cases (25 vs. 10%) (p < 0.05). In the present study, we found that women with COVID-19 had a more than twofold increased odds of preterm labor. History of preterm delivery was also associated with high twofold odds of preterm labor. Conclusion We observed a higher incidence rate of premature delivery in COVID-19 cases. Women with COVID-19 had a more than twofold increased odds of preterm labor. Considering prematurity has high morbidity and is regarded as the primary cause of mortality in children under 5 years old, more case-control studies are needed to ascertain the results.

Background The present study aimed to compare dietary intake and lifestyle behaviour in women with polycystic ovarian syndrome (PCOS) and healthy women. Methods One hundred and sixty healthy women (partner with male infertility) were recruited to a control group; 168 women with PCOS (diagnosed on ultrasound) were recruited to a case study group for this cross‐sectional comparative study. The case group was classified into three phenotypes based on the presence or absence of menstrual disorder (M), hyperandrogenism (HA) and polycystic ovary according to sonography (PCO): HA+PCO (n = 53), PCO+M (n = 57) and M+HA+PCO (n = 66). Dietary intake and lifestyle behaviour were measured using a food frequency questionnaire and a lifestyle questionnaire. Results The mean energy (P < 0.001) and fat (P < 0.001) intakes were greater in PCOS groups compared to the control group. The average energy and fat intakes were greater in HA+M+PCO group after age and body mass index (BMI) adjustment compared to the other phenotypes (P < 0.001). In comparison with the control group, lifestyle scores were lower in the PCOS group in the fields of physical activity, weight and nutrition control after age and BMI adjustment (P < 0.001). The average score of lifestyle in the fields of physical activity, weight and nutrition control, and psychological health was lower in the phenotype HA+M+PCO compared to the other phenotypes (P < 0.001). Conclusions A limited energy and fat intake is strongly recommended in Iranian women with PCOS, especially for phenotype HA+M+PCO. Consultation with respect to improvement of psychological health and the importance of weight and nutrition control, as well as appropriate physical activity, is advocated, especially in patients with phenotype HA+M+PCO.
