In a previous study of 24 healthy women, vaginal microbiome composition became less diverse between the second and third trimesters of pregnancy and just before delivery was enriched with Lactobacillus species, likely contributing to vertical transmission of these bacteria during vaginal birth.21 In a study of 10 newborns in Venezuela, within hours of delivery, the intestinal tracts of infants born vaginally were colonized by Lactobacillus and Prevotella, whereas infants delivered operatively acquired bacteria present on the mother's skin and the hospital environment, such as Staphylococcus, Proprionibacterium, and Corynebacterium.15 Quiz Ref ID Our findings, based on a large group of 6 - week - old infants, indicated that Lactobacillus also contributes to the microbial environment of the gut but to a lesser extent than Bifidobacteria, Bacteroides, and Streptococcus.

«Previous studies at a few sites had shown that large trees suffer more than small trees during and after droughts, and our theory suggested this should be a globally consistent pattern, but this project was the first to test this hypothesis globally.»

«Previous studies at a few sites had shown that large trees suffer more than small trees during and after droughts, and our theory suggested this should be a globally consistent pattern, but this project was the first to test this hypothesis globally,» said Los Alamos National Laboratory's Nate McDowell, a renowned forest ecologist and plant physiologist who coauthored a paper in the journal Nature Plants highlighting this research.

Our sample can be characterized as high risk (baseline ECBI T score > 55) 42 or at the borderline of clinical (T score > 60), 34 which is typical of previous randomized clinical trials of parent training for young children.41 The results across methods in this study are impressive given that effect sizes have been shown to be associated with the magnitude of symptom severity at baseline, 43 and thus it is typically more difficult to find large effects in prevention than in intervention trials.

A recent rapid review to update the evidence for components of the Healthy Child Programme in England also found few studies of interventions aiming to promote child development outcomes in all families with children in the 0 — 5 age range.10 We reviewed a larger number of primary studies than either of these previous publications.

Recent research conducted in mainland China found that obesity prevalence was higher among children in wealthier families, 4 but the patterns were different in Hong Kong with higher rates of childhood obesity among lower income families.4 5 Hong Kong, despite having a per capita gross domestic product of Hong Kong dollar (HK$) 273 550, has large income differences between rich and poor as reflected by a high Gini coefficient of 0.539 reported in 2016; approximately 20 % of the population are living in poverty as defined by a monthly household income below half of the Hong Kong median.6 It is widely accepted that population health tend to be worse in societies with greater income inequalities, and hence low - income families in these societies are particularly at risk of health problems.7 In our previous study, children from Hong Kong Chinese low - income families experienced poorer health and more behavioural problems than other children in the population at similar age.8 Adults from these families also reported poorer health - related quality of life (HRQOL), 9 with 6.1 % of the parents having a known history of mental illness and 18.2 % of them reporting elevated level of stress.
