Aims/hypothesis Islet autoimmunity may progress to adult-onset diabetes. We investigated whether circulating odd-chain
fatty acids (OCFA) 15:0 and 17:0, which are inversely associated with type 2 diabetes, interact with autoantibodies against
GAD65 (GAD65Ab) on the incidence of adult-onset diabetes.
Methods We used the European EPIC-InterAct case–cohort study including 11,124 incident adult-onset diabetes cases and
a subcohort of 14,866 randomly selected individuals. Adjusted Prentice-weighted Cox regression estimated HRs and 95%
CIs of diabetes in relation to 1 SD lower plasma phospholipid 15:0 and/or 17:0 concentrations or their main contributor,
dairy intake, among GAD65Ab-negative and -positive individuals. Interactions between tertiles of OCFA and GAD65Ab
status were estimated by proportion attributable to interaction (AP).
Results Low concentrations of OCFA, particularly 17:0, were associated with a higher incidence of adult-onset diabetes in
both GAD65Ab-negative (HR 1.55 [95% CI 1.48, 1.64]) and GAD65Ab-positive (HR 1.69 [95% CI 1.34, 2.13]) individuals. The combination of low 17:0 and high GAD65Ab positivity vs high 17:0 and GAD65Ab negativity conferred an HR
of 7.51 (95% CI 4.83, 11.69), with evidence of additive interaction (AP 0.25 [95% CI 0.05, 0.45]). Low dairy intake was
not associated with diabetes incidence in either GAD65Ab-negative (HR 0.98 [95% CI 0.94, 1.02]) or GAD65Ab-positive
individuals (HR 0.97 [95% CI 0.79, 1.18]).
Conclusions/interpretation Low plasma phospholipid 17:0 concentrations may promote the progression from GAD65Ab
positivity to adult-onset diabetes.
