[Local Data] Caffeine intake and mineral metabolism among various maternal vitamin D statuses
A recently published local study is the first to demonstrate that health consequences of caffeine intake during pregnancy may differ across women based on their serum 25(OH)D concentrations. Peripheral blood samples from 181 randomly selected healthy pregnant women were collected. Information of their demographic and dietary intake were collected via questionnaires.
[Science Update] Recommendations for optimal prenatal supplementation for women in the US
In order to lower the risk of a variety of pregnancy and infant health issues, a study offers evidence-based recommendations for the optimal level of vitamins in prenatal supplements for women in the US. In total, 13 vitamins and 3 related nutrients have been reviewed. These recommendations are intended for the general population.
[Literature library] Complexity in HMO mixture composition and gut ecosystem
A recently published in vitro study demonstrated that infant gut ecosystem may benefit from more diverse human milk oligosaccharides (HMOs) mixtures, which would support various bifidobacterial communities and may safeguard the gut barrier from pro-inflammatory imbalances.
[Science Update] The impact of nutritional interventions on preschoolers' cognitive development
A recently published review article investigated the impacts of nutritional interventions on preschool children’s (aged 2 – 6 years) cognitive outcomes. In total, 12 Randomized Controlled Trials (RCTs) performed between 2000 and 2021 were included in the systemic review. Cognitive outcomes were assessed via various standardized cognitive tests*. The study showed that cognitive development of undernourished preschoolers can be positively impacted by nutritional interventions such as micronutrient supplementation. Besides, increasing fish consumption improves cognitive abilities of nourished children.
[Local Data] Hong Kong parents’ intention to vaccinate their children against COVID-19
The Hong Kong government has officially stated that children as young as five years old would be able to get COVID-19 vaccines starting from January 2022. One of the most critical elements affecting how many children will be covered by the campaign is parents' intention to vaccinate their children. Recently, a larger-scale local survey has revealed the intention of Hong Kong parents to vaccinate their children against COVID-19, as well as the correlations.
[Science Update] Phospholipid content in Chinese human milk across lactation stages
Phospholipids (PL) are critical for infant growth and neurodevelopment. A part of the Chinese study (the Maternal Nutrition and Infant Investigation) collected 2,270 human milk samples from 0 to 400 days postpartum in 6 regions of China, to determine the major classes of PLs in human milk and their respective levels across lactation stages.
[Local Data] Serum vitamin D level and in vitro fertilization
Data from a local retrospective study revealed that vitamin D deficiency and insufficiency were prevalent among infertile women in Hong Kong. The association between serum 25(OH)D level before ovarian stimulation and the cumulative live birth rate (CLBR) of the first in vitro fertilization (IVF) cycle have been further investigated.
