Exploring the link between dietary inflammatory index, inflammatory biomarkers, and sleep quality in adults with obesity: a pilot investigation
Authors' conclusion
These findings suggest that an anti-inflammatory diet can effectively reduce inflammation and BMI in people with obesity, but has a limited effect on sleep quality. Therefore, it is recommended that dietitians integrate anti-inflammatory dietary strategies for people with obesity into their clinical practice.
Study context
- Population
- Adults with obesity (F: 75; M: 49), mean age 42.20 ± 11.00 years, presenting to a dietary outpatient clinic in Malatya, November 2021–May 2022
- Participants
- 124 adults
- Exposure
- Higher vs lower Dietary Inflammatory Index score
- Outcome
- Relationship of DII (3-day dietary records) with inflammatory biomarkers and sleep quality
Methodological detailspilot investigation
- Pilot investigation
Main finding
As reported in the abstract
DII vs inflammatory biomarkers, BMI and sleep quality
- C-reactive protein (CRP) significantly higher in groups with higher Dietary Inflammatory Index (DII) score
- p = 0.006
- Correlation of DII with CRP
- r = 0.258; p = 0.004
- Correlation of DII with total cholesterol
- r = −0.243; p = 0.007
- Body Mass Index (BMI) increased as dietary inflammatory burden increased
- p = 0.009
- No significant correlation between DII and sleep quality
- p = 0.348
Observational data: associations, not effects.
