To investigate the initation time of breastfeeding, exclusive breastfeeding rates, and complementary feeding practices during the first six months of life among mothers who gave birth in a baby-friendly hospital. A cross-sectional study was conducted with 350 mothers. Demographic characteristics, obstetric history and information about breastfeeding initiation were collected at the hospital. Information about factors affecting breastfeeding duration and feeding practices of the infants were obtained at the end of six months. Some 97.4% of the mothers initiated breastfeeding, 60.1% within the first hour. Exclusive breastfeeding was maintained for six months in 38.9%. Low education levels of mother/father, random breastfeeding, rare breastfeeding at night, nipple problems, bottle/pacifier use, and lack of social support were found associated with early cessation. Planned pregnancy [odds ratio (OR=2.02)] and vaginal delivery (OR=0.3) were found as the most important factors in early initiation, whereas antepartum breastfeeding education (OR=7.17) was the most important factor for exclusive breastfeeding duration in the logistic analysis. More than half (61.1%) of the infants were partially/bottle fed for six months; the most common reason was the belief that breast milk was insufficient. Efforts to encourage mothers and society to breastfeed exclusively should be made as part of a primary public health strategy to prevent early cessation of breastfeeding.

Objective: To compare the relationship between the severity of anemia and depressive mood in the last trimester of pregnancy. Methods: A cross-sectional study, enrolled a total of 450 pregnant women who attended the antenatal clinics in their third trimester for their routine antenatal follow-up. Depressive symptoms were assessed by the Edinburgh Postnatal Depression Scale. The study group was divided into two groups according to presence of anemia; anemic group (Hb < 11 gr/L; n = 150) and non-anemic group (Hb ≥ 11 gr/L; n = 300) and depression scores were compared. Results: One hundred and fourteen (25.3%) women scored ≥13 points which were considered the cutoff value for depression on the EPDS. Anemia frequency was found as 33.3%. The total EPDS score was significantly higher in the anemic group (EPDS score 11 [min–max 0–29]) compared with the non-anemic group (EPDS score 7 [min–max 0–21]) (p = 0.000). Multiple regression analysis also revealed that serum Hb level was an independent factor for antenatal depressive mood. Conclusions: As anemia is associated with higher depressive symptom levels, it should be carefully considered during pregnancy. Prospective studies are needed to confirm our results.

Objectives: To Evaluate the effect of messenger ribonucleic acid (mRNA) vaccines developed for the coronavirus disease-19 (COVID-19) on ovarian reserve. Methods: This prospective cross sectional study was carried out between June and September 2021, in the Gynecology Polyclinics of a tertiary hospital, Ankara, Turkey, with 60 patients. Patients between the ages of 25-30 years old, who applied to the gynecology outpatient clinic and who were considering mRNA vaccination against severe acute respiratory syndrome coronavirus 2 were included in the study group, and those who did not plan to be vaccinated were included in the control group. Anti-müllerian hormone (AMH) was examined before vaccination (1-5 days before vaccination) and within 60-90 days after vaccination. In the unvaccinated group, AMH was examined once. Results: The mean age of the study group was 27.30±1.66 and of the control group was 27.40±1.69 (p0.05). There was no statistically significant difference between pre-vaccine and post-vaccine AMH values in the study group (p>0.05). Conclusion: It is of great value that people who are planning pregnancy and who have hesitation regarding the effect of vaccines on ovarian reserve should be carefully informed that vaccines, which are one of the most important means of fighting against COVID-19 infection, have no effect on AMH levels. Prospective larger studies with a longer follow-up period are needed to confirm our results.

Objective: To determine the impact of the presence and severity of nause and vomiting in pregnancy (NVP) on health-related quality of life in pregnant adolescents.Methods: Two hundred and fifty adolescent pregnant women were included in this study. The Rhodes test was performed to determine the severity of nausea and vomiting, and the self-reported 36-Item Short Form Survey (SF-36) Scale was administered. The study was divided into four groups according to nausea severity (no, mild, moderate, severe) groups and SF-36 scores were compared among the groups.Results: Of the 250 pregnant women included in the study, 74.5% of women reported NVP. Low scores on the SF-36 were found for all items with increasing severity of NVP, with the lowest scores in the severe NVP group and the highest scores in the group with no NVP (p = 0.001). Multivariable analyses showed that severity of NVP was the most important factor for both the physical (PCS) and mental component summary (MCS) scales. The number of living children was significantly associated with lower PCS scores and being unable to share problems with spouse/relatives was correlated with lower MCS scores. Conclusion: The negative impact of nausea and vomiting on health-related quality of life, emphasises the importance of psychological support and optimal management of NVP in pregnant adolescents.
