To identify factors associated with insomnia in perimenopausal women and understand the specific moderating role of tryptophan in the relationship between prolactin levels and insomnia.
Key Findings:
Serum prolactin levels positively correlated with insomnia, anxiety, and depression scores, indicating a significant relationship.
Prolactin levels were associated with sleep-onset difficulties and sleep maintenance problems, highlighting their impact on sleep quality.
Higher serum tryptophan levels strengthened the positive relationship between prolactin levels and insomnia severity, suggesting a potential therapeutic target.
Interpretation:
The findings suggest that tryptophan may enhance the effects of prolactin on insomnia, indicating a complex interplay between neuroendocrine factors and sleep disturbances in perimenopausal women, which aligns with existing literature on hormonal influences on sleep.
Limitations:
Cross-sectional design limits causal inferences.
Sample size may not be representative of all perimenopausal women.
Potential confounding factors not fully controlled, including reliance on self-reported measures.
Conclusion:
Understanding the moderating effect of tryptophan on prolactin's influence on insomnia may inform future research and therapeutic strategies for perimenopausal women.
A large Epic Cosmos analysis linked vaginal estrogen prescribing with lower rates of sepsis, hospital admission, and death following recurrent urinary tract infection, but researchers cautioned that prescribing may also mark broader differences in care.
