To identify and test the predictive power of potential independent risk factors of postpartum depressive symptoms during pregnancy and the perinatal period.
Methods
We conducted a case-control study where 132 women with postpartum depressive symptoms were selected as an index group and 264 women without depressive symptoms as a control group. Data related to sociodemographic status, medical, gynecologic, and obstetric history, pregnancy, and perinatal events were collected from standardized medical records.
Results
The strongest risk factors for postpartum depressive symptoms were sick leave during pregnancy and a high number of visits to the antenatal care clinic. Complications during pregnancy, such as hyperemesis, premature contractions, and psychiatric disorder were more common in the postpartum depressed group of women. No association was found between parity, sociodemographic data, or mode of delivery and postpartum depressive symptoms.
Conclusion
Women at risk for postpartum depression can be identified during pregnancy. The strongest risk factors, sick leave during pregnancy and many visits to the antenatal care clinic, are not etiologic and might be of either behavioral or biologic origin. The possibilities of genetic vulnerability and hormonal changes warrant further investigation to reach a more thorough understanding.

Very little is known about the prevalence and risk factors of postpartum depression among women with vaginal births without major pregnancy complications. This study aimed to assess the prevalence of postpartum depression and identify its characteristics 2 months after singleton vaginal delivery at or near term. This was an ancillary cohort study of the TRanexamic Acid for Preventing Postpartum Hemorrhage After Vaginal Delivery randomized controlled trial, which was conducted in 15 French hospitals in 2015-2016 and enrolled women with singleton vaginal deliveries after 35 weeks of gestation. After randomization, the characteristics of labor, delivery, and the immediate postpartum experience, including the experience of childbirth, were prospectively collected. Medical records provided women's other characteristics, particularly any psychiatric history. Of note, 2 months after childbirth, provisional postpartum depression diagnosis was defined as a score of ≥13 on the Edinburgh Postnatal Depression Scale, a validated self-administered questionnaire. The corrected prevalence of postpartum depression was calculated with the inverse probability weighting method to take nonrespondents into account. Associations between potential risk factors and postpartum depression were analyzed by multivariate logistic regression. Moreover, an Edinburgh Postnatal Depression Scale cutoff value of ≥11 was selected to perform a sensitivity analysis. The questionnaire was returned by 2811 of 3891 women (72.2% response rate). The prevalence rates of the provisional diagnosis were 9.9% (95% confidence interval, 8.6%-11.3%) defined by an Edinburgh Postnatal Depression Scale score of ≥13 and 15.5% (95% confidence interval, 14.0%-17.1%) with a cutoff value of ≥11. The characteristics associated with higher risks of postpartum depression in multivariate analysis were mostly related to prepregnancy characteristics, specifically age of <25 years (adjusted odds ratio, 1.8; 95% confidence interval, 1.1-2.9) and advanced age (adjusted odds ratio, 1.8; 95% confidence interval, 1.2-2.6), migration from North Africa (adjusted odds ratio, 2.9; 95% confidence interval, 1.9-4.4), previous abortion (adjusted odds ratio, 1.4; 95% confidence interval, 1.0-2.0), and psychiatric history (adjusted odds ratio, 2.9; 95% confidence interval, 1.8-4.8). Some characteristics of labor and delivery, such as induced labor (adjusted odds ratio, 1.5; 95% confidence interval, 1.1-2.0) and operative vaginal delivery (adjusted odds ratio, 1.4; 95% confidence interval, 1.0-2.0), seemed to be associated with postpartum depression. In addition, bad memories of childbirth in the immediate postpartum were strongly associated with postpartum depression symptoms at 2 months after giving birth (adjusted odds ratio, 2.4; 95% confidence interval, 1.3-4.2). Approximately 10% of women with vaginal deliveries have postpartum depression symptoms, assessed by a score of ≥13 on the depression scale that was used at 2 months. Prepregnancy vulnerability factors; obstetrical characteristics, such as induced labor and operative vaginal delivery; and bad memories of childbirth 2 days after delivery were the main factors associated with this provisional diagnosis. A screening approach that targets risk factors may help to identify women at risk of postpartum depression who could benefit from early intervention.

The use of long hormonal contraceptives can disrupt the balance of estrogen in the body, resulting in abnormal cell changes. This study aimed to determine a correlation between the duration of hormonal contraception and risk of cervical cancer. This study used a case-control design. The population were patients who had examined at a cancer installation and obstetrics-gynecology polyclinic Dr. Sardjito Hospital in 2018. Case samples were 95 women have cervical cancer diagnosis and control were 95 women with a negative pap smear. Sampling with random sampling. Dependent variable cervical cancer and independent variable the duration of hormonal contraception are obtained from medical records. Cervical cancer is assessed by doctor’s diagnosis. Data analysis used logistic regression. Results showed that 44.7% of samples used long-term hormonal contraception (over 5 years). Length of use of hormonal contraception had a significant correlation with the incidence of cervical cancer (p-value < 0.01). Hormonal contraceptive use more than 5 years have a risk 4.2 times (95% CI 1.01-5.69) of cervical cancer than using less than 5 years after being controlled with the first marriage age and parity

Low-dose oral contraceptives (OC) were approved by the Japanese Ministry of Health, Labor and Welfare in 1999, yet despite their contraceptive and non-contraceptive health benefits, only 5% of the target population use them. Fear of increased cancer risk, particularly breast cancer, is one reason for this. Due to low OC uptake and low screening participation, a paucity of data is available on the risk of OC use and breast cancer in Japanese women. The present study investigated OC use and breast cancer risk, as well as menstrual, reproductive and family factors. This was a clinic-based case-control study of women aged 20-69yrs who had undergone breast screening between January 2007 and December 2013 in central Tokyo. In all, 28.8% of the participants had experience with OC use. Cases were 155 women with a pathologically confirmed diagnosis of breast cancer. Controls were the remaining 12,333 women. Increased age was a significant risk factor for breast cancer (p<0.001). A lower risk was found in premenopausal women presently taking OC compared to never users (OR 0.45; 95% CI 0.22-0.90) after adjusting for age, parity and breast feeding, and a family history of breast cancer. Increased age rather than OC use had a greater effect on breast cancer risk. This risk may be decreased in premenopausal women with OC use, but further long-term prospective studies are necessary.

To assess the risk of oral contraceptives on the occurrence of cervical cancer. A hospital-based case-control study was conducted. Sixty women patients with histologically confirmed invasive cervical cancer and 180 healthy women as the control group who attended the King Chulalongkorn Memorial Hospital, Bangkok, Thailand were recruited. Information about the use of oral contraceptives and other cervical cancer risk factors were obtained from personal interviews. The risk factors were evaluated by using odds ratio (OR). 60 women with invasive cervical cancer and 180 healthy controls were interviewed by the investigators. Compared with non-users, patients who had ever used or currently used oral contraceptive had an increased risk of cervical cancer (OR 1.45; 95% CI 0.79-2.64). However the risk was not statistically significant. Considering the duration of use, patients who had used oral contraceptives for 3 years or less did not have an increased risk of cervical cancer (OR 0.78; 95% CI 0.39-1.77). Nevertheless, the odds ratio of oral contraceptive pill use for more than 3 years was 2.57 (95% CI 1.22-5.49) which was statistically significant. Long-term use of oral contraceptive might be a cofactor that increases the risk of cervical carcinoma. Further investigations should be conducted to confirm this risk. However, Pap smear has to be done routinely in long-term oral pill users.
