Evaluating Oxidative Stress in Menopause

Study Overview
=================
Brief Summary
-----------------
Thiol disulfide levels will be determined using venous blood samples from pre- and postmenopausal women to evaluate oxidative stress in menopause. Furthermore, oxidative stress will be assessed according to age, and years since the start of menopause. Also, whether the presence of menopause related osteoporosis has any association with oxidative stress will be determined.

Detailed Description
-----------------
A total of 77 subjects are divided into two groups: study group (postmenopausal women) and control group premenopausal women). Biometric data such as age, bmi, obstetric anamnesis, history of komorbidities, PAP smear results are recorded. Mammography results, dexa scores of post menopausal women are also obtained. Venous blood samples from all subjects are collected. Thiol disulfide levels will be determined from serum samples. Thiol disulfide levels will first be compared between the study and the control group in order to determine the oxidative stress in menopause. In secondary evaluation years of menopause, age, and dexa scores will be included.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Postmenopausal/Study<br>Women older than 45 years of age and who have not had any menstruation for the past 12 months are considered as having entered menopause. These women are included in this group. | Other: Thiol disulfide level<br>* Venous blood is collected from all subjects and thiol disulfide levels will be determined from the serum samples obtained from the venous blood.<br>|
| Premenopausal/Control<br>Healthy women who are still having regular menstruations are included in this group | Other: Thiol disulfide level<br>* Venous blood is collected from all subjects and thiol disulfide levels will be determined from the serum samples obtained from the venous blood.<br>|
