Insights
A pro-inflammatory diet is linked to poorer cardiovascular health in adults, but not children. Early dietary interventions may prevent future cardiovascular disease by addressing inflammation.
Area of Science:
- Nutrition Science
- Cardiovascular Health
- Public Health
Background:
- A pro-inflammatory diet is a potential modifiable risk factor for cardiovascular disease (CVD).
- Understanding diet's impact on preclinical CVD phenotypes across the life course is crucial for prevention.
Purpose of the Study:
- To examine the associations between two inflammatory diet scores and preclinical cardiovascular phenotypes in children and adults.
- To investigate if these associations differ between childhood and mid-life.
Main Methods:
- Utilized data from the Child Health CheckPoint Study, including 1771 children and 1793 parents.
- Derived two inflammatory diet scores from the NaSSDA survey: one literature-derived and one GlycA-biomarker-derived.
- Assessed cardiovascular phenotypes including vascular structure and function using measures like carotid intima-media thickness and pulse wave velocity.
Main Results:
- In adults, higher inflammatory diet scores were associated with adverse cardiovascular function (e.g., faster pulse wave velocity) and microvascular structure.
- Associations were attenuated when body mass index (BMI) was included in analyses.
- Little evidence of associations was found in children aged 11-12 years.
Conclusions:
- Findings suggest cumulative adverse effects of a pro-inflammatory diet on cardiovascular health manifest by mid-life.
- Preventive strategies targeting diet and inflammation should be implemented in childhood to mitigate long-term cardiovascular risks.
Background And Aims:
Pro-inflammatory diet may be a modifiable risk factor for cardiovascular disease. We examine associations of two inflammatory diet scores with preclinical cardiovascular phenotypes at two life course stages.
Methods:
Participants: 1771 children (49% girls) aged 11-12 years and 1793 parents (87% mothers, mean age 43.7 (standard deviation 5.2) years) in the Child Health CheckPoint Study.
Measures:
23 items in the Australian National Secondary Students' Diet and Activity (NaSSDA) survey were used to derive two inflammatory diet scores based on: 1) published evidence of associations with C-reactive protein (literature-derived score), and 2) empirical associations with CheckPoint's inflammatory biomarker (glycoprotein acetyls, GlycA-derived score). Cardiovascular phenotypes assessed vascular structure (carotid intima-media thickness, retinal vessel calibre) and function (pulse wave velocity, blood pressure).
Analyses:
Linear regression models were conducted, adjusted for age, sex, socioeconomic position and child pubertal status, plus a sensitivity analysis also including BMI (z-score for children).
Results:
In adults, both inflammatory diet scores showed small associations with adverse cardiovascular function and microvascular structure. Per standard deviation higher GlycA-derived diet score, pulse wave velocity was 0.17 m/s faster (95% CI 0.11 to 0.22), mean arterial pressure was 1.85 mmHg (1.34-2.37) higher, and retinal arteriolar calibre was 1.29 μm narrower (-2.10 to -0.49). Adding BMI to models attenuated associations towards null. There was little evidence of associations in children.
Conclusions:
Our findings support cumulative adverse effects of a pro-inflammatory diet on preclinical cardiovascular phenotypes across the life course. Associations evident by mid-life were not present in childhood, when preventive measures should be instituted.
