Migration status and the accompanying diversity in culture, foods and family norms, may be an important consideration for practitioners providing individualized care to treat and prevent complications among youth with diabetes. Approximately 20 % of youth in the US have ≥1 foreign-born parent. However, the proportion and characteristics of youth with diabetes and ≥1 foreign-born parent have yet to be described. Study participants (n = 3,086) were from SEARCH for Diabetes in Youth, a prospective multi-center study in the US. Primary outcomes of interest included HbA1c, body mass index and barriers to care. Multivariable analyses were carried out using logistic regression and analysis of covariance. Approximately 17 % of participants with type 1 diabetes (T1D) and 22 % with type 2 diabetes (T2D) had ≥1 foreign-born parent. Youth with T1D and ≥1 foreign-born parent were less likely to have poor glycemic control [adjusted odds ratio (OR) (95 % confidence interval): 0.70 (0.53, 0.94)]. Among youth with T2D, those with ≥1 foreign-born parent had lower odds of obesity [adjusted OR (95 % CI): 0.35 (0.17, 0.70)]. This is the first study to estimate the proportion and characteristics of youth with diabetes exposed to migration in the US. Research into potential mechanisms underlying the observed protective effects is warranted.
