Infant adiposity may be related to later metabolic health. Maternal metabolite profiling reflects both genetic and environmental influences and allows elucidation of metabolic pathways associated with infant adiposity. In this multi-ethnic Asian cohort, we aimed to (i) identify maternal plasma metabolites associated with infant adiposity and other birth outcomes and (ii) investigate the maternal characteristics associated with those metabolites.

Article Synopsis
  • The study systematically reviewed the link between maternal dietary patterns during pregnancy and risks of preterm birth and offspring birth size, analyzing 36 studies and involving over 167,000 participants.
  • Healthy dietary patterns, rich in fruits, vegetables, and lean proteins, were found to lower the risk of preterm birth and were linked to higher birth weight.
  • In contrast, unhealthy dietary patterns associated with refined grains and processed foods increased the likelihood of lower birth weight and showed a trend toward higher preterm birth risk.

Diet in the first month postpartum, otherwise known as "the confinement diet" in Asia, has unique characteristics that are influenced by traditions, cultures, and beliefs. We aimed to characterize dietary patterns during confinement period in a multi-ethnic Asian cohort and examined their associations with postpartum depression (PPD) and anxiety (PPA). Dietary intakes of 490 women were ascertained in the first month postpartum using 3-day food diaries and dietary patterns were derived by factor analysis.

Background: Evidence linking maternal diet quality during pregnancy with infant birth outcomes is limited in Asia.

Objective: We investigated the association of maternal diet quality with the risk of preterm birth, offspring birth size, and adiposity in a multiethnic Asian birth cohort.

Design: Dietary intakes of 1051 pregnant women were ascertained at 26-28 wk of gestation with the use of 24-h recalls and 3-d food diaries, from which diet quality (score range: 0-100) was measured by the Healthy Eating Index for pregnant women in Singapore (HEI-SGP).

In this cross-sectional study, we evaluated the association of dietary fish intake with varying severity of diabetic retinopathy (DR) and retinal vascular caliber in Asians with type 2 diabetes mellitus. 357 Asians (median age: 58 years; 31% women; 78% Chinese) were recruited from a tertiary eye care institution in Singapore. Fish consumption was evaluated using a validated food frequency questionnaire.

Evidence on the association between sleep, diet, and eating behaviors in pregnant women is lacking. We examine this in a cohort of apparently healthy pregnant women. At 26-28 weeks gestation, 497 participants completed the Pittsburgh Sleep Quality Index to assess sleep and a 24-h recall to assess dietary intake.

Background: Maternal diet during pregnancy has been suggested to be an important early-life exposure that influences immune tolerance and the development of allergic diseases in offspring.

Methods: We examined the relationship between maternal dietary patterns assessed using 24-h recalls and food diaries at 26-28 weeks of pregnancy and the subsequent development of allergic outcomes in the offspring in the Growing Up in Singapore towards Healthy Outcomes (GUSTO) birth cohort. Exploratory factor analysis was used to characterize maternal dietary patterns during pregnancy.

Background: Maternal dietary patterns during pregnancy have been shown to influence infant birth outcomes. However, to our knowledge, only a few studies have examined the associations in Asian populations.

Objective: We characterized maternal dietary patterns in Asian pregnant women and examined their associations with the risk of preterm birth and offspring birth size.

Unlabelled: Little is known about the dietary patterns of Asian infants in the first year of life, nor of their associations with maternal socio-demographic factors. Based on the Growing Up in Singapore towards healthy Outcomes (GUSTO) mother-offspring cohort, cross-sectional dietary patterns were derived by factor analysis using 24-h recalls and food diaries of infants at 6-, 9- and 12-months of age. Dietary pattern trajectories were modeled by mapping similar dietary patterns across each age using multilevel mixed models.

Background: Maternal diet during pregnancy can influence fetal growth. However, the relation between maternal macronutrient intake and birth size outcomes is less clear.

Objective: We examined the associations between maternal macronutrient intake during pregnancy and infant birth size.
