Background: Previous work has shown that children 'left-behind' as a consequence of parental migration experience worse outcomes, although the majority of this evidence focuses on short- rather than long-term effects.
Methods: Using data from the Cebu Longitudinal Health and Nutrition Survey cohort (n = 1651), we assessed the association of paternal emigration (identified based on evidence of remittances sent back by mother's spouse) during childhood with the mental health and educational attainment at age 18 of Filipino children, adjusted for sex, socioeconomic position and paternal education. We explored whether timing of emigration, and household composition modified associations observed.
Findings: Children who had migrant fathers were found to be 1.24 times more likely to have high educational attainment at age 18 than children who did not have migrant fathers, although the association was imprecise (95 % confidence intervals: 0.83-1.85). We found no statistical evidence of a difference between children who experienced paternal migration compared to those who did not in terms of depressive symptoms or suicidal ideation at age 18. There was evidence that experiencing paternal migration in older childhood (≥10 years) was associated with better mental health. We found evidence that household composition modified associations for depressive symptoms.
Interpretation: This study does not suggest a detrimental long-term impact of paternal emigration on children 'left-behind, either for educational attainment or mental health. This may reflect beneficial effects of paternal migration and/or pre-existing socioeconomic and health differences amongst families who do and do not experience paternal migration.

This study investigates the genetic structure and demographic history of contemporary Thai populations from Tak and Ranong, two border provinces between Thailand and Myanmar with complex immigration histories. We analyzed 20 Y-SNP markers (327 samples) and 24 Y-STR profiles (241 samples), along with published datasets, and observed significant genetic differentiation between these regions. Tak is dominated by O2a2b1a1a (44.

Background: Previous studies identified clusters of first-episode psychosis (FEP) patients based on cognition and premorbid adjustment. This study examined a range of socio-environmental risk factors associated with clusters of FEP, aiming a) to compare clusters of FEP and community controls using the Maudsley Environmental Risk Score for psychosis (ERS), a weighted sum of the following risks: paternal age, childhood adversities, cannabis use, and ethnic minority membership; b) to explore the putative differences in specific environmental risk factors in distinguishing within patient clusters and from controls.
Methods: A univariable general linear model (GLS) compared the ERS between 1,263 community controls and clusters derived from 802 FEP patients, namely, low (n = 223) and high-cognitive-functioning (n = 205), intermediate (n = 224) and deteriorating (n = 150), from the EU-GEI study.

We present a new hierarchical Bayesian method using multilocus genotypes to estimate recent seed and pollen migration rates in a spatially explicit framework that incorporates distance effects separately for each type of dispersal. The method additionally estimates population allelic frequencies, population divergence values, individual inbreeding coefficients, individual maternal and paternal ancestries, and allelic dropout rates. We conduct a numerical simulation analysis that indicates that the method can provide reliable estimates of seed and pollen migration rates and allow accurate inference of spatial effects on migration, at affordable sample sizes (25-50 individuals/population) when population genetic divergence is not low (FST≥0.

Background: The advancements in second-/third-generation sequencing technologies, alongside computational innovations, have significantly enhanced our understanding of the genomic structure of Y-chromosomes and their unique phylogenetic characteristics. These researches, despite the challenges posed by the lack of population-scale genomic databases, have the potential to revolutionize our approach to high-resolution, population-specific Y-chromosome panels and databases for anthropological and forensic applications.
Objectives: This study aimed to develop the highest-resolution Y-targeted sequencing panel, utilizing time-stamped, core phylogenetic informative mutations identified from high-coverage sequences in the YanHuang cohort.
