Predisposing, Precipitating, and Perpetuating Factors of Insomnia in Cancer Survivors.
Misol Kwon, Miranda V McPhillips, Fanghong Dong and 3 others
PMID 38668908WHAT IT FOUND
In cancer survivors, anxiety, depression, and dysfunctional beliefs about sleep were strongly linked to clinical insomnia.
Being female appeared protective, while being a person of color increased risk. Alcohol, caffeine, and napping showed no significant association with insomnia severity.
Key findings
01Anxiety, depression, and dysfunctional sleep beliefs remained significantly associated with clinical insomnia after adjusting for other factors.
02Being a person of color was associated with a higher likelihood of clinical insomnia compared to non-Hispanic White participants.
03Common sleep hygiene behaviors like alcohol intake, caffeine use, and napping were not significantly associated with insomnia severity.

What it does not show
Cross-sectional design prevents causal conclusions; insomnia may worsen anxiety/depression, or vice versa. Sample was primarily White (88%) and recruited from a single comprehensive cancer center, limiting generalizability. Low prevalence of anxiety and depression in the sample may have reduced statistical power to detect associations. All data were self-reported, including sleep behaviors, which may be subject to social desirability bias. Did not assess potential confounders like socioeconomic status, menopausal status, pain, or stress levels.
The easy way to misread this
Do not assume that advising patients to reduce caffeine, alcohol, or napping will resolve their insomnia. This study found no significant association between these behaviors and insomnia severity, whereas psychological factors like anxiety and dysfunctional beliefs were strongly linked.
