To what extent do oral contraceptives influence mood and affect?

Area of Science:

• Reproductive Health
• Psychopharmacology
• Women's Mental Health

Background:

• Oral contraceptives (OCs) are widely used, yet their impact on mood and affect remains a subject of ongoing research.
• Understanding the nuanced effects of OCs on emotional well-being is crucial for informed clinical practice and patient counseling.

Purpose of the Study:

• To review existing literature on the effects of oral contraceptives (OCs) on mood, affect, and affect variability.
• To identify potential mediators and moderators of OC-related mood changes.

Main Methods:

• Systematic review of studies comparing oral contraceptive users with non-users.
• Inclusion of studies utilizing daily ratings of mood, affect, or affect variability.

Main Results:

• Oral contraceptive users exhibit less affect variability and reduced negative affect during menstruation compared to non-users.
• Identified potential risk factors for negative mood changes include a history of depression, psychiatric symptoms, dysmenorrhea, premenstrual symptoms, and family history of mood complaints.
• Hormonal ratios (progesterone to estrogen) and OC formulation (monophasic vs. triphasic) influence mood effects.

Conclusions:

• While most women experience beneficial mood effects from OCs, a subset reports negative mood changes.
• Further research is needed to investigate psychological factors, indirect pharmacological effects, and a broader range of affective experiences (positive and negative).
• Focusing on individual differences and risk factors is essential for understanding and managing OC-related mood disturbances.
