Adequate intakes of folate, vitamin B6, and vitamin B12 should be recommended for prevention of MetS suggests a recent study published in the JAMA Netw Open.

The associations of B vitamin status with metabolic syndrome (MetS) incidence among the US population remain unclear. A study was done to investigate intakes and serum concentrations of folate, vitamin B6, and vitamin B12 in association with MetS risk in a large US cohort.

This prospective study included Black and White young adults in the US who were enrolled from 1985 to 1986 and studied until 2015 to 2016. Diet was assessed using a validated diet history at examination years 0, 7, and 20. Serum concentrations of folate, vitamin B6, and vitamin B12 were assayed at examination years 0, 7, and 15 in a subset of 1430 participants. MetS was ascertained by clinic and laboratory measurements and self-reported medication use. Data were analyzed between January and July 2021.

Multivariable Cox proportional hazards regression models were used to calculate hazard ratios (HRs) and 95% CIs for the associations of energy-adjusted B vitamin intakes or serum B vitamin levels with incident MetS.

Results

• The study included 4414 participants, with 2225 Black individuals (50.4%) and 2331 women (52.8%). The mean (SD) age at baseline was 24.9 (3.6) years.

• A total of 1240 incident MetS cases occurred during the 30 years of follow-up.

• Compared with the lowest quintile of each energy-adjusted B vitamin intake, the HRs for incident MetS in the highest quintile were 0.39 for folate, 0.61 for vitamin B6, and 0.74 for vitamin B12 after adjustment for potential confounders.

• Similarly, significant inverse associations were observed in the subset with serum data on these B vitamins

This prospective cohort study found that intakes and serum concentrations of folate, vitamin B6, and vitamin B12 were inversely associated with incident MetS among Black and White young adults in the US.
