Recent Choline Intake Is Inversely Associated with Inflammation in Pregnancy - Evidence from the Canadian APrON...

Area of Science:

• Obstetrics and Gynecology
• Nutritional Science
• Biochemistry

Background:

• Maternal nutrition significantly influences pregnancy inflammation, impacting both maternal and fetal well-being.
• Inflammation during pregnancy is a critical factor for health outcomes.
• Dietary factors, like choline, are increasingly recognized for their role in modulating inflammatory processes.

Purpose of the Study:

• To investigate the association between maternal dietary choline intake and C-reactive protein levels in the third trimester.
• To explore how choline intake relates to markers of inflammation in pregnant individuals.
• To assess the impact of choline on pregnancy health through inflammation markers.

Main Methods:

• Utilized data from the Alberta Pregnancy Outcomes and Nutrition (APrON) cohort.
• Dietary choline intake was quantified using 24-hour dietary recalls.
• High-sensitivity C-reactive protein (hs-CRP) was measured in maternal blood, with statistical analysis using natural spline regression.

Main Results:

• A significant non-linear inverse relationship was observed between maternal choline intake and hs-CRP levels.
• Higher choline intake was associated with reduced odds of clinically elevated hs-CRP (cutoff 5 mg/L).
• Participants with choline intake >700 mg/d showed significantly lower odds of elevated hs-CRP compared to those with <200 mg/d.

Conclusions:

• Elevated dietary choline intake in pregnancy may be associated with reduced maternal inflammation.
• Adequate choline consumption is highlighted as potentially crucial for supporting maternal health during gestation.
• Further research into choline's role in pregnancy inflammation is warranted.
