Early Pregnancy Cravings, Dietary Intake, and Development of Abnormal Glucose Tolerance.

ABSTRACT: Little is known about the relationships between pregnancy cravings, maternal diet, and development of abnormal glucose tolerance.We examined relationships of pregnancy cravings with dietary intake and risk of developing isolated hyperglycemia (IH), impaired glucose tolerance (IGT), or gestational diabetes (GDM) later in pregnancy.Among 2,022 mothers in Project Viva, a prospective birth cohort recruited from medical practices in eastern Massachusetts between 1999 and 2002, we assessed type of pregnancy craving based on self-report at mean gestation of 10.9 weeks.The outcomes were cross-sectional dietary intake from a food frequency questionnaire and incident IH, IGT, or GDM determined by glucose tolerance screening at 26 to 28 weeks.We used linear regression to analyze the cross-sectional relationships between pregnancy cravings and dietary intake and multinomial logistic regression to analyze the prospective relationships among pregnancy cravings and development of IH, IGT, or GDM.During the first trimester, 443 (22%) women craved sweets, 225 (11%) craved salty foods, 261 (13%) craved savory foods, and 100 (4.9%) craved starchy foods. Sweet cravings were associated with increased intake of sucrose (1.9 g/day; 95% CI 0.1 to 3.7), total fat (1.5 g/day; 95% CI 0.1 to 2.9), and saturated fat (0.8 g/day; 95% CI 0.2 to 1.4); salty cravings were associated with increased fiber (0.7 servings/day; 95% CI -0.1 to 1.6); savory cravings were associated with increased n-3 fatty acids (0.10 g/day; 95% CI 0.02 to 0.17); and starchy cravings were associated with increased carbohydrates (8.0 g/day; 95% CI 0.3 to 15.7) and decreased total fat (-2.6 g/day; 95% CI -5.2 to -0.1). Salty cravings were associated with lower risk of GDM (adjusted odds ratio 0.34, 95% CI 0.12-0.97).New cravings in the first trimester of pregnancy were associated with dietary intake. Craving salty foods may predict reduced risk of developing GDM, whereas craving sweet food does not appear to alter one's risk.

Project description:This experiment was designed to determine the effects of variations in dietary energy intake on reproductive performance and gene expression of luteal and endometrium tissues in Large White (LW) and Meishan (MS) gilts during early and middle pregnancy. After insemination, 32 LW gilts were assigned to high and low (HEL and LEL, 14.23 and 12.56 MJ DE/kg, respectively) diet treatment groups, while 32 MS gilts were allocated to HEM and LEM (12.56 and 10.88 MJ DE/kg) groups. Gilts were slaughtered on days 35, 55 and 90 of gestation. The fetal survival and luteal progesterone (P4) concentration in the HEL group were higher on day 35 but lower on day 90 of gestation compared with the LEL group (P < 0.05) for LW gilts. However, fetal survival and luteal P4 concentration on day 35 of gestation were greater (P < 0.05) in the LEM group than in the HEM group for MS gilts, but no significant difference in mid-gestation was showed. The fetal weights of both breeds were higher for the high energy diets compared with the respective control group on day 90 of gestation (P < 0.05). In addition, the mRNA levels of P4 synthesis-related proteins had correlated with luteal P4 concentration in both breeds. Further, endometrial levels of uteroferrin (ACP5), retinol-binding protein 4 (RBP4) and secreted phosphoprotein 1 (SPP1) mRNA were upregulated in the HEL group on day 35 of gestation but ACP5 and SPP1 were downregulated on day 55 of gestation compared with the LEL group (P < 0.05) for LW gilts. In MS gilts, diet only affected the expression of SPP1 (P < 0.05). Our results revealed the differential sensitivity of LW and MS breeds to variations in dietary energy intake. For LW gilts, the HEL group improved fetal survival on day 35 but a sustained high energy diet decreased fetal survival on day 90 of gestation. The differences in dietary energy intake did not influence fetal survival on day 90 of gestation but the higher energy diet did increase fetal weight in the MS breed compared with the lower energy intake diet. These results may be due to differential luteal secretion activity and endometrium gene expression in these two breeds.

Project description:BackgroundMaternal abnormal glucose tolerance during pregnancy may adversely affect offspring cognition and behaviour, but few prospective studies investigated this association at multiple points throughout childhood.ObjectivesWe hypothesised that maternal abnormal glucose tolerance is associated with child cognitive and behavioural outcomes in early and mid-childhood.MethodsWe examined the associations of maternal abnormal glucose tolerance at 26-28 weeks of pregnancy with offspring cognitive and behavioural scores in 1421 children in the Project Viva pre-birth cohort. In early (mean 3.3 years) and mid-childhood (mean 7.9 years), we measured child cognition using validated instruments, the Kaufman Brief Intelligence Test, Wide Range Assessment of Memory and Learning, and the Wide Range Assessment of Visual Motor Abilities (WRAVMA); we assessed parent- and teacher-rated behavioural outcomes with the Strengths and Difficulties Questionnaire and the Behavioural Rating Inventory of Executive Function. We used linear regression models adjusted for potential confounders (maternal race/ethnicity, pre-pregnancy BMI, intelligence, age, parity, smoking status, education, and household income at enrolment, in addition to child's sex and age at assessment).ResultsOf 1421 mothers, 69 (4.9%) had gestational diabetes mellitus, 43 (3.0%) impaired glucose tolerance, 122 (8.6%) isolated hyperglycaemia, and 1187 (83.5%) normal glucose tolerance. Offspring born to women with gestational diabetes mellitus had lower total WRAVMA scores (-3.09 points; 95% CI -6.12, -0.05) in early childhood compared with offspring of women with normal glucose tolerance. None of the abnormal glucose tolerance categories during pregnancy were associated with any of the cognitive outcomes (verbal, non-verbal, and visual motor scores) or behavioural measures in mid-childhood.ConclusionsChildren born to mothers who had gestational diabetes mellitus had slightly lower scores on one cognitive test in early childhood. We found no evidence to support that maternal abnormal glucose tolerance was associated with cognitive or behavioural development in mid-childhood.
