Insomnia Disorder: Gender Issues Over the Lifespan

Area of Science:

• Sleep Medicine
• Neuroscience
• Gender Studies

Background:

• Insomnia disorder is a prevalent sleep disorder, disproportionately affecting women.
• Gender differences in insomnia are pronounced during key life stages: puberty, pregnancy, and menopause.
• Hormonal, physiological, relational, emotional, and environmental factors influence sleep disturbances in women.

Purpose of the Study:

• To review and synthesize empirical literature on gender differences in sleep physiology and insomnia.
• To examine prevalence, clinical characteristics, and contributing factors of insomnia across the lifespan.
• To explore sleep difficulties in sexual minority groups, including transgender individuals.

Main Methods:

• Comprehensive literature review of studies on gender and insomnia.
• Analysis of factors predisposing, precipitating, and perpetuating insomnia disorder.
• Inclusion of data on transgender populations regarding sleep issues.

Main Results:

• Significant gender disparities in insomnia prevalence and characteristics exist throughout life.
• Hormonal shifts and psychosocial factors during puberty, pregnancy, and menopause exacerbate these differences.
• Limited but emerging data highlight sleep difficulties in transgender individuals.

Conclusions:

• Biological and psychosocial factors are key to understanding gender differences in insomnia.
• Further research is needed to address the scarcity of literature, especially concerning sexual minorities.
• Investigating gender differences can inform personalized insomnia treatment and improve prognosis.
