Intake of antioxidant vitamins and trace elements during pregnancy and risk of advanced beta cell autoimmunity in the child.
Am J Clin Nutr 2008; 88(2):458-64AJ

Abstract

BACKGROUND

Type 1 diabetes may have its origins in the fetal period of life. Free radicals were implicated in the cause of type 1 diabetes. It was hypothesized that antioxidant nutrients could protect against type 1 diabetes.

OBJECTIVE

We assessed whether high maternal intake of selected dietary antioxidants during pregnancy is associated with a reduced risk of advanced beta cell autoimmunity in the child, defined as repeated positivity for islet cell antibodies plus >/=1 other antibody, overt type 1 diabetes, or both.

DESIGN

The study was carried out as part of the population-based birth cohort of the Type 1 Diabetes Prediction and Prevention Project. The data comprised 4297 children with increased genetic susceptibility to type 1 diabetes, born at the University Hospital of Oulu or Tampere, Finland, between October 1997 and December 2002. The children were monitored for diabetes-associated autoantibodies from samples obtained at 3-12-mo intervals. Maternal antioxidant intake during pregnancy was assessed postnatally with a self-administered food-frequency questionnaire, which contained a question about consumption of dietary supplements.

RESULTS

Maternal intake of none of the studied antioxidant nutrients showed association with the risk of advanced beta cell autoimmunity in the child. The hazard ratios, indicating the change in risk per a 2-fold increase in the intake of each antioxidant, were nonsignificant and close to 1.

CONCLUSION

High maternal intake of retinol, beta-carotene, vitamin C, vitamin E, selenium, zinc, or manganese does not protect the child from development of advanced beta cell autoimmunity in early childhood.
