Obstructive sleep apnea is associated with disturbances in nutrition-related biochemical markers among eutrophic adults
In eutrophic adults, moderate-to-severe OSA was linked to higher VLDL and triglyceride levels, and zinc levels differed across OSA severity groups. Higher AHI was independently associated with higher VLDL and triglycerides and lower magnesium after full adjustment, with sex-specific patterns.

Obstructive sleep apnea is associated with disturbances in nutrition-related biochemical markers among eutrophic adults The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 32/100 (low).
The Claim
Obstructive sleep apnea is associated with disturbances in nutrition-related biochemical markers among eutrophic adults
This conclusion is most relevant to: Eutrophic adults aged 20-59 years from the EPISONO cohort in São Paulo.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Obstructive sleep apnea is associated with disturbances in nutrition-related biochemical markers among eutrophic adults: Findings from the EPISONO cohort. (Sleep medicine, 2026) —
How It Works
The proposed biological pathway:
- ▸OSA causes intermittent hypoxia and sleep fragmentation
- ▸This may alter lipid metabolism and mineral homeostasis
- ▸Sex hormones modulate these metabolic pathways
- ▸Result: Higher VLDL/triglycerides and lower magnesium in OSA patients
Who Might Benefit
Evidence fit by population:
- ▸Eutrophic adults aged 20-59 years from the EPISONO cohort in São Paulo
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional design prevents causal inference
- ▸Sample limited to eutrophic adults from a single city, limiting generalizability
Frequently Asked Questions
What does 'eutrophic' mean in this study?▼
Eutrophic refers to individuals with normal body weight, typically defined by a BMI in the normal range.
Which biochemical markers were most strongly associated with OSA severity?▼
VLDL and triglycerides were higher in moderate-to-severe OSA, and magnesium was inversely associated with AHI in men.
Were there sex differences in the findings?▼
Yes, lipid markers and zinc were linked to AHI in women, while magnesium was inversely associated with AHI in men.
Can these results be used to recommend dietary changes for OSA patients?▼
No, the study is observational and does not test interventions; it only identifies associations that warrant further research.
