Epigenetics in Families: Covariance between Mother and Child Methylation Patterns.

ABSTRACT: Theory and research both point at epigenetic processes affecting both parenting behavior and child functioning. However, little is known about the convergence of mother and child's epigenetic patterns in families. Therefore, the current study investigated epigenetic covariance in mother-child dyads' methylation levels regarding four stress-regulation related genes (5HTT, NR3C1, FKBP5, and BDNF). Covariance was tested in a general population sample, consisting of early adolescents (M_age = 11.63, SD_age = 2.3) and mothers (N = 160 dyads). Results showed that mother and offspring 5HTT and NR3C1 methylation patterns correlated. Furthermore, when averaged across genes, methylation levels strongly correlated. These findings partially supported that child and parent methylation levels covary. It might be important to consider this covariance to understand maladaptive parent-child relationships.

Neonatal genome-wide methylation patterns in relation to birth weight in the Norwegian Mother and Child Cohort.

Project description:Although epigenetic regulation plays a critical role in embryonic development, few studies have examined the relationship of epigenome-wide methylation with fetal growth. Using the Infinium HumanMethylation450 BeadChip (Illumina, Inc., San Diego, California) in a substudy of 1,046 infants from the Norwegian Mother and Child Cohort Study (MoBa) enrolled between 1999 and 2008, we examined epigenome-wide cord blood DNA methylation in relation to birth weight. In multivariable-adjusted robust linear regression models, we identified differential methylation at 19 cytosine-guanine dinucleotides (CpGs) associated with either decreased (AT-rich interactive domain 5B (MRF1-like) (ARID5B), 2 CpGs) or increased (x-ray repair complementing defective repair in Chinese hamster cells 3 (XRCC3), 4 CpGs) birth weight. ARID5B knockout mice have less adipose tissue and significantly lower weight in the postnatal period. XRCC3 plays a key role in the maintenance of chromosome stability and the repair of DNA damage. Although there are fewer data on the other implicated genes, many of these genes have been shown to have roles in developmental processes. This constitutes the largest and most robust study of birth weight using an epigenome-wide methylation platform and offers potential insights into epigenetic mechanisms of fetal growth.

Neural synchrony in mother-child conversation: Exploring the role of conversation patterns.

Project description:Conversations are an essential form of communication in daily family life. Specific patterns of caregiver-child conversations have been linked to children's socio-cognitive development and child-relationship quality beyond the immediate family environment. Recently, interpersonal neural synchronization has been proposed as a neural mechanism supporting conversation. Here, we present a functional near-infrared spectroscopy (fNIRS) hyperscanning study looking at the temporal dynamics of neural synchrony during mother-child conversation. Preschoolers (20 boys and 20 girls, M age 5;07 years) and their mothers (M age 36.37 years) were tested simultaneously with fNIRS hyperscanning while engaging in a free verbal conversation lasting for 4 min. Neural synchrony (using wavelet transform coherence analysis) was assessed over time. Furthermore, each conversational turn was coded for conversation patterns comprising turn-taking, relevance, contingency and intrusiveness. Results from linear mixed-effects modeling revealed that turn-taking, but not relevance, contingency or intrusiveness predicted neural synchronization during the conversation over time. Results are discussed to point out possible variables affecting parent-child conversation quality and the potential functional role of interpersonal neural synchronization for parent-child conversation.

Association between mother-child sexual communication and HPV vaccine uptake.

Project description:To examine the association between mother-child communication about sex, sexually transmitted diseases (STDs), and contraception/condoms and HPV vaccine uptake by gender.Women (n = 1372) with ? 1 child aged 9-17 years receiving care in reproductive health clinics in Southeast Texas were asked to complete a self-administered questionnaire between September 2011 and October 2013.The majority of mothers with ? 1 eligible daughter (n = 886) reported having talked about 'sex' (77.7%), 'STDs' (76.6%) and 'contraception' (73.2%) with their daughters. The respective figures for mothers with ? 1 son (n = 836) were 68.8%, 69.0% and 65.3%. Mothers who discussed sex, STDs, or contraception with their daughters compared to those who did not were more likely to report that their daughter initiated (? 1 dose) HPV vaccination after adjusting for confounders (all p < .05). Similarly, mother-son discussions about STDs or condoms, but not sex, were associated with HPV vaccine initiation for their sons compared to those who did not discuss these topics. These associations were not significant with regard to HPV vaccine completion (3 doses) for neither daughters nor sons.Mother-child communication on STDs and contraception/condoms is associated with HPV vaccine initiation, but not completion, among both daughters and sons.

Daily hassles, mother-child relationship, and behavior problems in Muslim Arab American adolescents in immigrant families.

Project description:ObjectiveThis longitudinal study examines reciprocal and dynamic relations among daily hassles, the mother-child relationship, and adolescent behavior problems and whether the relations differed by sociodemographic variables.MethodThree waves of data about adolescent daily hassles, quality of the mother-child relationship, and adolescent behavior problems were collected from 454 Arab Muslim adolescents and their immigrant mothers over a 3-year period. Cross-lagged structural equation modeling (SEM) was used to examine reciprocal relations among the study variables.ResultsRelations between the mother-child relationship and adolescent behavior problems were reciprocal, with a poor mother-child relationship contributing to greater behavior problems and behavior problems contributing to a decline in the quality of the mother-child relationship. Relations involving daily hassles were unidirectional: A better mother-child relationship contributed to fewer daily hassles and behavior problems contributed to more daily hassles but daily hassles did not contribute to more behavior problems. Father's education was the only sociodemographic variable that was significant: Adolescents with more highly educated fathers had a better mother-child relationship and fewer behavioral problems.ConclusionsFindings suggest that Arab American Muslim adolescents with behavior problems are differentially exposed to daily hassles but daily hassles are not the best point of intervention. Bidirectional relations between the mother-child relationship and adolescent behavior problems suggest intervening to improve the mother-child relationship and manage symptoms of adolescent behavior problems.

Covariance Between Genotypic Effects and its Use for Genomic Inference in Half-Sib Families.

Project description:In livestock, current statistical approaches utilize extensive molecular data, e.g., single nucleotide polymorphisms (SNPs), to improve the genetic evaluation of individuals. The number of model parameters increases with the number of SNPs, so the multicollinearity between covariates can affect the results obtained using whole genome regression methods. In this study, dependencies between SNPs due to linkage and linkage disequilibrium among the chromosome segments were explicitly considered in methods used to estimate the effects of SNPs. The population structure affects the extent of such dependencies, so the covariance among SNP genotypes was derived for half-sib families, which are typical in livestock populations. Conditional on the SNP haplotypes of the common parent (sire), the theoretical covariance was determined using the haplotype frequencies of the population from which the individual parent (dam) was derived. The resulting covariance matrix was included in a statistical model for a trait of interest, and this covariance matrix was then used to specify prior assumptions for SNP effects in a Bayesian framework. The approach was applied to one family in simulated scenarios (few and many quantitative trait loci) and using semireal data obtained from dairy cattle to identify genome segments that affect performance traits, as well as to investigate the impact on predictive ability. Compared with a method that does not explicitly consider any of the relationship among predictor variables, the accuracy of genetic value prediction was improved by 10-22%. The results show that the inclusion of dependence is particularly important for genomic inference based on small sample sizes.

Weight patterns among mother-child pairs in the Middle East and North African Region.

Project description:AimWe aim to evaluate weight status in mother-child household pairs and patterns specific to over-nutrition households and double burden households.MethodsWe used nationally representative data from the most recent Demographic and Health Survey (2001-2014) in the Middle East & North African (MENA) Region (n = 45,104) to examine weight status of mother-child dyads. Under-nutrition households were defined as mothers with underweight and children with wasting; over-nutrition households as mothers with overweight/obesity and children with overweight; and double burden households as mothers with underweight and children with overweight or mothers with overweight/obesity mother and children with wasting. Survey-adjusted multinomial logistic regression were used to quantify predictors of weight patterns.ResultsAcross the MENA region, 8.6% of households were experiencing double burden malnutrition, 11% were experiencing over-nutrition and 0.2% were experiencing under-nutrition. Wealthier households with older mothers, higher birth-order children, more educated parents and private water access were more likely to be over-nutrition or double burden households. Compared to over-nutrition households, double burden households were poorer and more likely to have a child with low birthweight.ConclusionsOver-nutrition is the most common unhealthy weight pattern, followed by double-burden; socioeconomic status and birth weight are consistent predictors of unhealthy mother-child pairs.

Determinants of dietary patterns of Ghanaian mother-child dyads: A Demographic and Health Survey.

Project description:Having a comprehensive understanding of a population's dietary patterns is a key component of any effective strategy for preventing malnutrition, planning, and putting nutrition interventions and policies into place. It's interesting to note that information on dietary patterns of Ghana's vulnerable subpopulations of women and children is lacking. The purpose of this study is to characterize the dietary patterns of women (15-49 years old) and their young children (0-3 years old), as well as to investigate into the socioeconomic and demographic factors influencing the characterized dietary patterns. The sociodemographic information and food consumption of mother-child dyads (n = 1,548) were collected for this nationally representative cross-sectional study. Principal component analysis and multiple variable logistic regression were used, respectively, to determine the dietary patterns of dyads and the determinants of the identified dietary patterns. For women and children, respectively, four dietary patterns ('Beverage & sugary based', 'Meat based', 'Indigenous- tuber based' and 'Indigenous- grain based') and two ('Indigenous' and 'Milk, Meat, & cereal based') emerged. Ethnicity, wealth quintiles, parity, seasonality, dyad's age, body mass index, education, residency, marital status, and household size were the socioeconomic / demographic determinants of the dietary patterns. To sum up for women and children, meat based and indigenous staple based dietary patterns were identified, with several important socioeconomic and demographic variables acting as predictors of the dietary patterns. The identified dietary patterns and their determinants may serve as a basis for nutrition intervention and policies for women and children in Ghana.

Mother-child neural synchronization is time linked to mother-child positive affective state matching.

Project description:In the first years of life, in which self-regulation occurs via external means, mother-child synchronization of positive affect (PA) facilitates regulation of child homeostatic systems. Mother-child affective synchrony may contribute to mother-child synchronization of neural systems, but limited research has explored this possibility. Participants were 41 healthy mother-child dyads (56% girls; Mage = 24.76 months; s.d. = 8.77 months, Range = 10-42 months). Mothers' and children's brain activities were assessed simultaneously using near-infrared spectroscopy while engaging in dyadic play. Mother and child PA during play were coded separately to characterize periods in which mothers and children (i) matched on high PA, (ii) matched on low/no PA or (iii) showed a mismatch in PA. Models evaluated moment-to-moment correlations between affective matching and neural synchrony in mother-child dyads. Greater positive affective synchrony, in which mother and child showed similarly high levels of PA but not similarly low levels of PA, was related to greater synchrony in medial and lateral frontal and temporoparietal regions. Age moderated associations between mother and child neural activities but only during moments of high PA state matching. Positive, synchronous mother-child interactions may foster greater neural responding in affective and social regions important for self-regulation and interpersonal bonds.

Patterns of Father Involvement and Child Development among Families with Low Income.

Project description:This study examined patterns of father involvement and their relations with social, behavioral, and cognitive development among low-income children < 5 years. Latent class analysis on data from 2650 fathers (Mage = 29.35 years) in the Supporting Healthy Marriages program revealed four father involvement patterns: (1) High positive involvement (48%); (2) engaged but harsh discipline (42%); (3) low cognitive stimulation (8%); and (4) lower involvement (2%). The low cognitive stimulation pattern was associated with greater father- and mother-reported child behavior problems and lower child socioemotional and cognitive functioning. The engaged but harsh discipline pattern was associated with more father-reported child behavior problems. These findings highlight the need for active engagement of fathers in parenting interventions to promote child development.

CMCompare webserver: comparing RNA families via covariance models.

Project description:A standard method for the identification of novel non-coding RNAs is homology search by covariance models. Covariance models are constructed for specific RNA families with common sequence and structure (e.g. transfer RNAs). Currently, there are models for 2208 families available from Rfam. Before being included into a database, a proposed family should be tested for specificity (finding only true homolog sequences), sensitivity (finding remote homologs) and uniqueness. The CMCompare webserver (CMCws) compares Infernal RNA family models to (i) identify models with poor specificity and (ii) explore the relationship between models. The CMCws provides options to compare new models against all existing models in the current Rfam database to avoid the construction of duplicate models for the same non-coding RNA family. In addition, the user can explore the relationship between two or more models, including whole sets of user-created family models. Visualization of family relationships provides help in evaluating candidates for clusters of biologically related families, called clans. The CMCws is freely available, without any login requirements, at http://rna.tbi.univie.ac.at/cmcws, and the underlying software is available under the GPL-3 license.
