Long-chain polyunsaturated fatty acids in infant formula and cardiovascular markers in childhood

Area of Science:

• Pediatrics
• Cardiovascular Health
• Nutritional Science

Background:

• Infant nutrition plays a critical role in long-term health outcomes.
• Long-chain polyunsaturated fatty acids (LCPUFAs) are essential nutrients for infant development.
• Previous research suggests potential benefits of LCPUFAs for cardiovascular health.

Purpose of the Study:

• To determine if infant formula supplemented with LCPUFAs influences cardiovascular markers in early childhood.
• To compare cardiovascular profiles of children fed LCPUFA-supplemented formula versus standard formula.

Main Methods:

• Utilized data from the Wheezing Illnesses Study Leidsche Rijn birth cohort (2,468 newborns, 2001-2014).
• Assessed infant feeding via questionnaires.
• Measured blood pressure, carotid intima-media thickness (CIMT), and carotid distension at age 5.
• Employed multivariable linear regression to compare cardiovascular markers between formula groups before and after LCPUFA supplementation, controlling for secular trends with a breastfed control group.

Main Results:

• Formula-fed children receiving LCPUFA-supplemented formula (n=48) showed no significant differences in systolic or diastolic blood pressure, or carotid distension compared to those on standard formula (n=163).
• However, children on LCPUFA-supplemented formula exhibited a higher CIMT (18.6 μm).
• The control group of breastfed children showed no significant differences in blood pressure or CIMT, but higher carotid distension after the supplementation period.

Conclusions:

• Consumption of infant formula supplemented with LCPUFAs does not appear to confer a more favorable cardiovascular profile in early childhood.
• The observed increase in CIMT in the LCPUFA group warrants further investigation.
• Findings suggest that LCPUFA supplementation in infant formula may not provide the anticipated cardiovascular benefits.
