Hyperglycemia and lower diet quality in pregnant overweight women and increased infant size at birth and at 13 months of age - STEPS study
Conclusions: Maternal prepregnancy overweight increases risk of hyperglycemia in late-pregnancy and increased infant size at birth and 13 months possibly predisposing the infant to health risks later in life. (C) 2013 Elsevier Ireland Ltd. All rights reserved.</p
Sexually Dimorphic Associations between Maternal Factors and Human Milk Hormonal Concentrations
While human milk composition is characterised by marked dynamicity, we are far from having a clear picture of what factors drive this variation. Hormones in human milk are known to vary according to specific maternal phenotypes, but limited evidence shows the infant also has a role in determining milk composition. The present study aimed to investigate the interplay between maternal and infant characteristics in relation to human milk hormonal profile. In total, 501 human milk samples from mothers recruited in the Finnish STEPS cohort study (Steps to the healthy development) were analysed. Pre-pregnancy and pregnancy maternal data, socioeconomic status and infant characteristics at birth were collated. Leptin, adiponectin, insulin-like growth factor-1 and cyclic Glycine-Proline in milk were measured. Multivariate analysis of variance (MANOVA) and linear regression were utilised for statistical analysis. Sex-specific interactions with maternal factors were observed, as the infant sex mediated associations between gestational diabetes and milk adiponectin (p = 0.031), birth-mode and total protein (p = 0.003), maternal education and insulin-like growth factor-1: cyclic Glycine-Proline ratio (p = 0.035). Our results suggest that changes in human milk composition are associated with interactions between maternal and infant characteristics and pathophysiological factors. Future work should expand on these findings and further explore the link between hormonal profiles in human milk and infant outcomes
Gestational weight gain charts for different body mass index groups for women in Europe, North America, and Oceania
BackgroundGestational weight gain differs according to pre-pregnancy body mass index and is related to the risks of adverse maternal and child health outcomes. Gestational weight gain charts for women in different pre-pregnancy body mass index groups enable identification of women and offspring at risk for adverse health outcomes. We aimed to construct gestational weight gain reference charts for underweight, normal weight, overweight, and grades 1, 2 and 3 obese women and to compare these charts with those obtained in women with uncomplicated term pregnancies.MethodsWe used individual participant data from 218,216 pregnant women participating in 33 cohorts from Europe, North America, and Oceania. Of these women, 9065 (4.2%), 148,697 (68.1%), 42,678 (19.6%), 13,084 (6.0%), 3597 (1.6%), and 1095 (0.5%) were underweight, normal weight, overweight, and grades 1, 2, and 3 obese women, respectively. A total of 138, 517 women from 26 cohorts had pregnancies with no hypertensive or diabetic disorders and with term deliveries of appropriate for gestational age at birth infants. Gestational weight gain charts for underweight, normal weight, overweight, and grade 1, 2, and 3 obese women were derived by the Box-Cox t method using the generalized additive model for location, scale, and shape.ResultsWe observed that gestational weight gain strongly differed per maternal pre-pregnancy body mass index group. The median (interquartile range) gestational weight gain at 40weeks was 14.2kg (11.4-17.4) for underweight women, 14.5kg (11.5-17.7) for normal weight women, 13.9kg (10.1-17.9) for overweight women, and 11.2kg (7.0-15.7), 8.7kg (4.3-13.4) and 6.3kg (1.9-11.1) for grades 1, 2, and 3 obese women, respectively. The rate of weight gain was lower in the first half than in the second half of pregnancy. No differences in the patterns of weight gain were observed between cohorts or countries. Similar weight gain patterns were observed in mothers without pregnancy complications.ConclusionsGestational weight gain patterns are strongly related to pre-pregnancy body mass index. The derived charts can be used to assess gestational weight gain in etiological research and as a monitoring tool for weight gain during pregnancy in clinical practice
EFSA Panel on Dietetic Products, Nutrition, and Allergies (NDA); Scientific Opinion on Dietary Reference Values for fats, including saturated fatty acids, polyunsaturated fatty acids, monounsaturated fatty acids, trans fatty acids, and cholesterol
This Opinion of the EFSA Panel on Dietetic Products, Nutrition, and Allergies (NDA) deals with the setting of Dietary Reference Values (DRVs) for fats. A lower bound of the reference intake range for total fat of 20 energy % (E%) and an upper bound of 35 E% are proposed. Fat intake in infants can gradually be reduced from 40 E% in the 6-12 month period to 35-40 E% in the 2nd and 3rd year of life. For specific fatty acids the following is proposed: saturated fatty acid (SFA) and trans fatty acid intake should be as low as possible; not to set any DRV for cis-monounsaturated fatty acids; not to formulate a DRV for the intake of total cis-polyunsaturated fatty acids (PUFA); not to set specific values for the n-3/n-6 ratio; to set an Adequate Intake (AI) of 4 E% for linolenic acid; not to set any DRV for arachidonic acid; not to set an UL for total or any of the n-6 PUFA; to set an AI for alpha-linilenic acid (ALA) of 0.5 E%; not to set an UL for ALA; to set an AI of 250 mg for eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) for adults; to set an AI of 100 mg DHA for infants (>6 months) and young children <24 months; to increase by 100-200 mg preformed DHA in addition to the AI for adults as an adequate supply of n-3 long chain PUFA during pregnancy and lactation; not to set any DRV for conjugated linoleic acid. For cholesterol it was decided not to propose a reference value beside the limitation on the intake of SF

The ADIPS pilot National Diabetes in Pregnancy Audit Project
Background: Limited resources are available to compare outcomes of pregnancies complicated by diabetes across different centres. Aims: To compare the use of paper, stand alone and networked electronic processes for a sustainable, systematic international audit of diabetes in pregnancy care. Methods: Development of diabetes in pregnancy minimum dataset using nominal group technique, email user survey of difficulties with audit tools and collation of audit data from nine pilot sites across Australia and New Zealand. Results: Seventy-nine defined data items were collected: 33 were for all women, nine for those with gestational diabetes (GDM) and 37 for women with pregestational diabetes. After the pilot, four new fields were requested and 18 fields had queries regarding utility or definition. A range of obstacles hampered the implementation of the audit including Medical Records Committee processes, other medical/non-medical staff not initially involved, temporary staff, multiple clinical records used by different parts of the health service, difficulty obtaining the postnatal test results and time constraints. Implementation of electronic audits in both the networked and the stand-alone settings had additional problems relating to the need to nest within pre-existing systems. Among the 496 women (45 type 1; 43 type 2, 399 GDM) across the nine centres, there were substantial differences in key quality and outcome indicators between sites. Conclusions: We conclude that an international, multicentre audit and benchmarking program is feasible and sustainable, but can be hampered by pre-existing processes, particularly in the initial introduction of electronic methods
Dietary fats and atherosclerosis from childhood to adulthood
Background: The association of dietary fat distribution with markers of subclinical atherosclerosis during early life is unknown. We examined whether success in achieving the main target of an infancy-onset dietary intervention based on the distribution of dietary fat was associated with aortic and carotid intima-media thickness (IMT) and distensibility from childhood to young adulthood. Methods: In the prospective randomized controlled Special Turku Coronary Risk Factor Intervention Project trial, personalized dietary counseling was given biannually to healthy children from infancy to young adulthood. The counseling was based on Nordic Nutrition Recommendations, with the main aim of improving the distribution of dietary fat in children's diets. IMT and distensibility of the abdominal aorta and common carotid artery were measured repeatedly at ages 11 (n = 439), 13 (n = 499), 15 (n = 506), 17 (n = 477), and 19 years (n = 429). The targeted distribution of dietary fat was defined as a ratio of saturated fatty acids to monounsaturated and polyunsaturated fatty acids of Results: Individuals who achieved the main intervention target had lower aortic IMT (age- and sex-adjusted mean difference 10.4 ”m; 95% confidence interval: 0.3 to 20.5 ”m) and better aortic distensibility (0.13% per 10 mm Hg; 95% confidence interval: 0.00% to 0.26% per10 mm Hg) compared with their peers who did not meet the target. Conclusions: Achieving the main target of an infancy-onset dietary intervention, reflecting dietary guidelines, was favorably associated with aortic IMT and distensibility during the early life course. These data support the recommendation of favoring unsaturated fat to enhance arterial health
Attainment of targets of the 20-year infancy-onset dietary intervention and blood pressure across childhood and young adulthood: the Special Turku Coronary Risk Factor Intervention Project (STRIP)
We examined whether success in achieving the key targets of an infancy-onset 20-year dietary intervention was associated with blood pressure (BP) from infancy to young adulthood. In the prospective randomized STRIP (Special Turku Coronary Risk Factor Intervention Project; n=877 children), dietary counseling was provided biannually based on the Nordic Nutrition Recommendations primarily to improve the quality of dietary fat in children's diets and secondarily to promote intake of vegetables, fruits, and whole grains. Dietary data and BP were accrued annually from the age of 13 months to 20 years. The dietary targets for fat quality were defined as the ratio of saturated fatty acids to monounsaturated and polyunsaturated fatty acids P=0.03) and diastolic BP (mean [SE] diastolic BP, 60.4 [0.2], 60.5 [0.2], 59.9 [0.2], and 59.9 [0.3] mm Hg; P=0.02). When the lowest age-specific quintile of dietary cholesterol was added as an additional target, the association with systolic BP remained significant (P=0.047), but the association with diastolic BP attenuated (P=0.13). Achieving the key targets of an infancy-onset 20-year dietary intervention, reflecting dietary guidelines, was favorably albeit modestly associated with systolic and diastolic BP from infancy to young adulthood
