Abstract

In a California population, we previously observed increased neural tube defect (NTD) risks associated with maternal intakes of periconceptional diets predicting higher glycaemic responses and higher sucrose. Our objective here was to replicate these results in a larger study of multiple regions within the United States. This population-based case-control study included deliveries from 1997 to 2003 from the National Birth Defects Prevention Study. NTD cases were infants or fetuses born with spina bifida or anencephaly. Infants without malformations were eligible as controls. Interview participation was 71% among case mothers and 68% among control mothers. There were 720 NTD case and 4699 control mothers with completed interviews included in analyses. Diet was assessed using a 58-item food frequency questionnaire focusing on the year before conception, whereas cereals, beverages and supplement use was assessed periconceptionally. We found no increased risks of NTD-affected pregnancies with increased intakes (adjusted for kcal/day) of sucrose, glucose, fructose or with maternal diets with a higher glycaemic load. The reasons for current findings to be inconsistent with previous findings are unknown.
