Higher physical activity scores and healthier nutrition-related behaviors are associated with lower odds of insomnia among female nurses
In a cross-sectional study of 328 female nurses in Taiwan, higher physical activity scores (AOR=0.92, 95% CI: 0.85-0.99) and healthier nutrition-related behaviors (AOR=0.91, 95% CI: 0.84-0.98) were associated with lower odds of insomnia. Working 10-12 hours per day was associated with higher odds of insomnia (AOR=2.21, 95% CI: 1.20-4.07).

Higher physical activity scores and healthier nutrition-related behaviors are associated with lower odds of insomnia among female nurses The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).
The Claim
Higher physical activity scores and healthier nutrition-related behaviors are associated with lower odds of insomnia among female nurses
This conclusion is most relevant to: Female hospital nurses in Taiwan with at least one year of work experience (n=328).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸How physical activity and nutrition are associated with sleep health among female nurses: A cross-sectional study. (Work (Reading, Mass.), 2026) —
How It Works
The proposed biological pathway:
- ▸Physical activity may improve sleep through regulation of circadian rhythms and reduction of stress
- ▸Healthy nutrition may support neurotransmitter synthesis and hormonal balance
- ▸Combined lifestyle factors may reduce hyperarousal and improve sleep drive
- ▸Result: Lower odds of insomnia
Who Might Benefit
Evidence fit by population:
- ▸Female hospital nurses in Taiwan with at least one year of work experience (n=328)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional design prevents causal inference
- ▸Convenience sampling may limit generalizability to all female nurses
- ▸Self-reported measures of physical activity, nutrition, and insomnia may introduce recall bias
Frequently Asked Questions
What was the sample size and population of this study?▼
The study included 328 female hospital nurses in Taiwan with at least one year of work experience.
Did the study find a causal relationship between physical activity and insomnia?▼
No, due to the cross-sectional design, the authors note that causal inferences cannot be drawn; only associations were found.
What specific work factor was associated with higher insomnia odds?▼
Working 10-12 hours per day was associated with higher odds of insomnia (AOR=2.21, 95% CI: 1.20-4.07).
How were physical activity and nutrition measured?▼
Physical activity and nutrition-related behaviors were assessed using health-promotion lifestyle scales.
