Association Between Hormonal Birth Control, Substance Use, and Depression.

Area of Science:

• Women's Health
• Psychiatry
• Pharmacology

Background:

• Depression is a prevalent mental health concern among college-aged women.
• Understanding the influence of substance use and hormonal contraception on mood is crucial for public health.
• Existing research has not fully elucidated the complex interplay between hormonal birth control, cannabis, and alcohol on depression symptoms.

Purpose of the Study:

• To investigate the relationship between hormonal birth control use, cannabis (CB) use, alcohol consumption, and depression symptoms in college-aged women.
• To determine if there are differential impacts of these factors on depression.
• To explore potential interactions between substance use and hormonal birth control on depression.

Main Methods:

• Utilized survey data from 3,320 college-aged women over a 2-year period.
• Assessed depression symptoms using the Patient Health Questionnaire-9 (PHQ-9).
• Employed a between-subjects ANOVA to analyze the effects of hormonal birth control, cannabis, and alcohol use on depression scores.

Main Results:

• Women using hormonal birth control reported lower depression scores compared to non-users (12.1% vs. 15.2%).
• Hormonal birth control users showed higher scores on assessments for alcohol and cannabis use.
• Significant effects were found for hormonal birth control use, cannabis use, alcohol use, and a significant interaction between cannabis and hormonal birth control use on depression scores.

Conclusions:

• Hormonal birth control use may be associated with a reduction in depressive symptoms among college-aged women.
• A potential interaction exists between cannabis use and hormonal birth control use concerning depression symptoms, distinct from alcohol's impact.
• Further research is warranted to understand the mechanisms underlying these associations and the differing roles of cannabis and alcohol in depression.
