- Abstract
Background: Betaine supplementation results in lower body weight and fat mass and higher lean mass in animals and adult humans. However, the relation between maternal betaine status and offspring birth weight and body composition is less known., Objective: The aim was to examine the association between maternal betaine status and neonatal birth size and adiposity in an Asian mother-offspring cohort., Design: We included 955 pregnant women whose plasma betaine concentrations were measured at 26-28 wk of gestation. Neonatal anthropometric values were measured at birth, and abdominal adipose tissue compartments were assessed by MRI in a subset of infants (n = 307) in the first 14 d after birth. Multivariate general linear models were used to adjust for gestational age; fetal sex; and maternal age, height, education, ethnicity, prepregnancy body mass index, and plasma folate, vitamin B-12, and choline concentrations., Results: The mean ± SD plasma concentration of betaine was 13.2 ± 2.7 μmol/L (range: 5.3-25.0 μmol/L). After adjustment for covariates, higher maternal plasma betaine was associated with lower birth weight (β: -57.6 g; 95% CI: -109.9, -5.3 g), shorter birth length (β: -0.29 cm per 5-μmol/L increment; 95% CI: -0.55, -0.03 cm), smaller head circumference (-0.20 cm; 95% CI: -0.38, -0.02 cm), smaller midupper arm circumference (-0.16 cm; 95% CI: -0.30, -0.03 cm), lower volumes of abdominal superficial subcutaneous adipose tissue (-4.53 mL; 95% CI: -8.70, -0.36 mL), and a higher risk of small-for-gestational-age birth (OR: 1.57; 95% CI: 1.05, 2.35)., Conclusions: Higher maternal betaine status was generally associated with smaller infant birth size and less abdominal fat mass. Further studies are needed to replicate these findings and to understand their biological mechanisms. This study was registered at clinicaltrials.gov as NCT01174875., (© 2016 American Society for Nutrition.)

- Abstract
Although epidemiological studies suggest that offspring of women with preeclampsia are at increased risk to higher blood pressures and cardiovascular disease, little is known about the nature of blood pressures between the mother and her offspring. As blood pressures comprise of both pulsatile (systolic blood pressure [SBP] and pulse pressure [PP]) and stable (diastolic blood pressure [DBP]) components, and they differ between central and peripheral sites, we sought to examine maternal peripheral and central blood pressure components in relation to offspring early childhood blood pressures. A prospective birth cohort of 567 Chinese, Malay, and Indian mother-offspring with complete blood pressure information were studied. Maternal brachial artery SBP, DBP, and PP were measured at 26 to 28 weeks gestation; and central SBP and PP were estimated from radial artery waveforms. Offspring brachial artery SBP, DBP, and PP were measured at 3 years of age. Associations between continuous variables of maternal blood pressures (peripheral SBP, DBP, PP, central SBP, and PP) and offspring blood pressures (peripheral SBP, DBP, and PP) were examined using multiple linear regression with adjustment for maternal characteristics (age, education level, parity, smoking status, alcohol consumption and physical activity during pregnancy, and pre-pregnancy BMI) and offspring characteristics (sex, ethnicity, BMI, and height at 3 years of age). In the multivariate models, offspring peripheral SBP increased by 0.08 (95% confidence interval 0.00-0.17, P = 0.06) mmHg with every 1-mmHg increase in maternal central SBP, and offspring peripheral PP increased by 0.10 (0.01-0.18, P = 0.03) mmHg for every 1-mmHg increase in maternal central PP. The relations of maternal-offspring peripheral blood pressures (SBP, DBP, and PP) were positive but not statistically significant, and the corresponding values were 0.05 (-0.03 to 0.13; P = 0.21), 0.03 (-0.04 to 0.10; P = 0.35), and 0.05 (-0.02 to 0.13; P = 0.14), respectively. Maternal central pulsatile blood pressure components (SBP and PP) during pregnancy are associated with higher blood pressures in the offspring. This positive correlation is already evident at 3-years old. Studies are needed to further evaluate the effects of maternal central pulsatile blood pressure components during pregnancy and long-term cardiovascular health in the offspring.

- Abstract
Background: Appetitive traits in childhood such as food responsiveness and enjoyment of food have been associated with body mass index (BMI) in later childhood. However, data on appetitive traits during infancy in relation to BMI in later childhood are sparse. We aimed to relate appetitive traits in infancy to subsequent BMI and weight gain up to 24 months of age., Methods: Data of 210 infants from the Singapore GUSTO mother-offspring cohort was obtained. The Baby Eating Behavior Questionnaire (BEBQ) and the Child Eating Behavior Questionnaire (CEBQ) were administered to mothers when their offspring were aged 3 and 12 months respectively. Height and weight of offspring were measured at ages 3, 6, 9,12,15,18 and 24 months. The association of appetitive traits with both BMI z-score and weight gain were evaluated using multivariate linear regression., Results: Food responsiveness at 3 months was associated with higher BMI from 6 months up to 15 months of age (p < 0.01) and with greater weight gain between 3 and 6 months of age (p = 0.012). Slowness in eating and satiety responsiveness at 3 months was significantly associated with lower BMI at 6 months (p < 0.01) and with less weight gain between 3 to 6 months of age (p = 0.034). None of the appetitive traits at 12 months were significantly associated with BMI or weight gain over any time period., Conclusion: Early assessment of appetitive traits at 3 months of age but not at 12 months of age was associated with BMI and weight gain over the first two years of life., Trial Registration: Clinical Trials identifier NCT01174875.

- Abstract
Introduction: There is currently a lack of representative data for local gestational age-specific size-at- birth percentile charts. Existing charts also suffer from limitations relating to the measurement of gestational age (GA) and an outdated population. We aim to construct reference values and charts for size-at-birth from 35 to 41 weeks, based on the healthy local population., Materials and Methods: Prospective observational birth cohort study which recruited pregnant mothers from the 2 major public hospitals with obstetric service in Singapore, at <14 weeks gestation and data was collected for birth weight, length and head circumference of infants born from November 2009 to May 2011. Percentile curves were created separately for male and female infants using the lambda-mu-sigma (LMS) method. The new percentile curves were then compared with other internationally published growth charts., Results: Smoothened curves for birth weight, length and head circumference centiles were created from 863 infants (460 males, 403 females). Male infants consistently exceeded female infants in all 3 variables at each GA. For a male and female Singapore infant at 38 weeks gestation, the 10-50-90th centile values for weight would be 2663-3096-3597 vs. 2571-2966-3417 grams, for length 46.4-48.6-51.1 vs. 45.6-48.0-50.4 cm, and for head circumference 32.0-33.5-35.2 vs. 31.4-32.9-34.6 cm. There was no statistically significant difference between ethnic groups. On comparing our birth weight curves with data from Finland across all gestations, birth weights in our term infants (GA ≥37 weeks) were found to be lower across the 10-50-90th percentiles., Conclusion: The new centile charts in this study may be used as reference charts for size-at-birth for a subgroup of near-term and term infants. The use of foreign charts may lead to misclassification of small for gestational age (SGA) or large for gestational age (LGA) infants.

- Abstract
Context: Gestational hyperglycemia increases the risk of obesity and diabetes in offspring later in life., Objective: We examined the relationship between gestational glycemia and neonatal adiposity in a multiethnic cohort of Singaporean neonates., Design: A prospective mother-offspring cohort study recruited 1247 pregnant mothers (57.2% Chinese, 25.5% Malay, 17.3% Indian) and performed 75-g, 2-hour oral glucose tolerance tests at 26-28 weeks' gestation; glucose levels were available for 1081 participants. Neonatal anthropometry (birth weight, length, triceps, and subscapular skinfolds) was measured, and percentage body fat (%BF) was derived using our published equation. Associations of maternal glucose with excessive neonatal adiposity [large for gestational age; %BF; and sum of skinfolds (∑SFT)>90th centile] were assessed using multiple logistic regression analyses., Results: Adjusting for potential confounders we observed strong positive continuous associations across the range of maternal fasting and 2-hour glucose in relation to excessive neonatal adiposity; each 1 SD increase in fasting glucose was associated with 1.31 [95% confidence interval (CI) 1.10-1.55], 1.72 (95% CI 1.31-2.27) and 1.64 (95% CI 1.32-2.03) increases in odds ratios for large for gestational age and %BF and ∑SFT greater than the 90th centile, respectively. Corresponding odds ratios for 2-hour glucose were 1.11 (95% CI 0.92-1.33), 1.55 (95% CI 1.10-2.20), and 1.40 (95% CI 1.10-1.79), respectively. The influence of high maternal fasting glucose on neonatal ∑SFT was less pronounced in Indians compared with Chinese (interaction P=.005)., Conclusions: A continuous relationship between maternal glycemia and excessive neonatal adiposity extends across the range of maternal glycemia. Compared with Chinese infants, Indian infants may be less susceptible to excessive adiposity from high maternal glucose levels.

- Abstract
Background/objectives: Prediction equations are commonly used to estimate body fat from anthropometric measurements, but are population specific. We aimed to establish and validate a body composition prediction formula for Asian newborns, and compared the performance of this formula with that of a published equation., Subjects/methods: Among 262 neonates (174 from day 0, 88 from days 1-3 post delivery) from a prospective cohort study, body composition was measured using air-displacement plethysmography (PEA POD), with standard anthropometric measurements, including triceps and subscapular skinfolds. Using fat mass measurement by PEA POD as a reference, stepwise linear regression was utilized to develop a prediction equation in a randomly selected subgroup of 62 infants measured on days 1-3, which was then validated in another subgroup of 200 infants measured on days 0-3., Results: Regression analyses revealed subscapular skinfolds, weight, gender and gestational age were significant predictors of neonatal fat mass, explaining 81.1% of the variance, but not triceps skinfold or ethnicity. By Bland-Altman analyses, our prediction equation revealed a non-significant bias with limits of agreement (LOA) similar to those of a published equation for infants measured on days 1-3 (95% LOA: (-0.25, 0.26) kg vs (-0.23, 0.21) kg) and on day 0 (95% LOA: (-0.19, 0.17) kg vs (-0.17, 0.18) kg). The published equation, however, exhibited a systematic bias in our sample., Conclusions: Our equation requires only one skinfold site measurement, which can significantly reduce time and effort. It does not require the input of ethnicity and, thus, aid its application to other Asian neonatal populations.

- Abstract
An 11-year-old boy with congenital hepatic fibrosis presented with cyanosis at the National University Hospital. Echocardiogram revealed a structurally normal heart with good ventricular function. A pulmonary cause of his cyanosis was suggested on macroaggregated albumin scan and selective pulmonary artery angiogram. Arterial hypoxaemia secondary to intrapulmonary arteriovenous shunting in chronic liver cirrhosis can lead to permanent cyanosis. The potential for a complete reversal of this condition after liver transplantation indicates that arterial hypoxaemia, rather than being a contraindication, should be a reason for early liver transplantation.
