Sleep characteristics and risk factors in patients of insomnia comorbid with anxiety.

Researchers studied 221 people with insomnia to understand how anxiety affects their sleep patterns. They divided participants into two groups: those with anxiety symptoms (163 people) and those without (58 people), then compared their sleep quality using questionnaires and week-long sleep tracking devices worn on the wrist.

The study found that people with both insomnia and anxiety reported much worse sleep quality and more daytime problems than those with insomnia alone. Interestingly, while they felt their sleep was terrible, the tracking devices showed their actual sleep time was similar to the non-anxiety group. However, they did spend significantly more time lying in bed trying to sleep. The research also revealed that people who had insomnia for 3-10 years were at highest risk of developing anxiety alongside their sleep problems.

Three factors strongly predicted anxiety severity: poor sleep efficiency (how much of your time in bed is actually spent sleeping), frequent sleep disturbances during the night, and problems functioning during the day due to poor sleep. Depression symptoms were also closely linked with anxiety in insomnia patients.

What this means for patients: If you're experiencing both insomnia and anxiety, early treatment is crucial. The longer insomnia persists untreated, the more likely anxiety will develop. Acupuncture has been studied as a complementary approach for both insomnia and anxiety, potentially addressing the interconnected nature of these conditions by promoting relaxation and regulating sleep-wake cycles. Research suggests acupuncture may help improve sleep quality and reduce anxiety symptoms without the side effects of medications. If you're considering acupuncture for insomnia and anxiety, seek a licensed acupuncturist with experience treating sleep disorders and mental health conditions.

This study examined 221 insomnia patients, comparing those with comorbid anxiety (n=163, BAI≥10) to those without (n=58, BAI<10) using validated scales (PSQI, ISI, BDI, BAI) and 7-day actigraphy monitoring. The anxiety group demonstrated significantly elevated subjective sleep disturbance scores (PSQI, ISI) and depression symptoms (BDI) (all P<0.001), yet objective sleep parameters (TST, SE, SOL, WASO) showed no significant differences except increased time in bed (P=0.017). Spearman correlations confirmed positive associations between BAI grades and PSQI, ISI, and BDI scores (P<0.05). Logistic regression identified disease duration of 36-120 months as a significant risk factor for comorbidity development. Ordinal regression revealed sleep efficiency (P=0.008), sleep disturbances (P<0.001), and daytime dysfunction (P=0.043) as predictors of anxiety severity. Clinical takeaway: Patients with insomnia-anxiety comorbidity exhibit substantial subjective-objective sleep discrepancy; early intervention is critical as chronicity increases anxiety risk. Assessment should address sleep efficiency, nocturnal disturbances, and functional impairment.
