Proper nutrition and optimal weight status in pregnancy are important for both the mother and her child. The present study was aimed at assessment of maternal food and nutrient intake, dietary supplement use, dietary patterns, and weight during pregnancy. Additionally, associations between maternal weight, socio-demographic and perinatal factors and advanced beta cell autoimmunity in the offspring were examined.
The results from a one-year cohort of mothers entering the ongoing Type 1 Diabetes Prediction and Prevention (DIPP) study in 1998–99 (n = 797) suggested that healthy food choices were positively correlated with maternal age and education. Dietary supplements were used by 85% of the women. However, the intake of vitamin D did not meet the recommendation and folic acid intake was inadequate in 44% of the pregnant women when both food and supplementation intakes were taken into account.
Seven dietary patterns were identified in 3730 pregnant women who entered the DIPP study between 1997 and 2002. The ‘healthy’, the ‘low-fat foods’ and the ‘alcohol and butter’ dietary patterns were positively associated with maternal age and education. The ‘fast food’ dietary pattern was positively associated and the ‘alcohol and butter’ pattern was inversely associated with the rate of maternal weight gain during pregnancy.
Altogether, 4093 children and their mothers comprised the study population in which the relationships between maternal initial body mass index, weight gain rate, and the development of beta cell autoimmunity in the offspring were examined. Maternal weight status during pregnancy was not related to the risk of advanced beta cell autoimmunity. A higher level of maternal education was significantly associated with a decreased risk of advanced beta cell autoimmunity in children.
More attention should be paid to nutritional guidance among Finnish pregnant women, especially as regards young and less well educated women. Dietary patterns may be useful for risk group identification and they may offer a framework for further research concerning diet and health outcomes among mothers and their children.
