Examining the interdependence of parent-child dyads: Effects on weight loss and maintenance.
Ontology highlight
ABSTRACT: Background
This study aimed to further elucidate correlated weight changes in parent-child dyads enrolled in family-based treatment (FBT) by modeling the interdependence of weight changes during treatment.Methods
Parent-child dyads (n = 172) with overweight/obesity (child mean zBMI = 2.16 ± 0.39; parent mean BMI = 37.9 ± 9.4 kg/m2 ) completed 4 months of FBT and were randomized to one of three 8-month maintenance interventions (Social Facilitation Maintenance [SFM]-high dose, SFM-low dose or control). Weight/height was measured at 0, 4 and 12 months. Structural equation models simultaneously estimated the effect that an individual had on their own (actor effect) and on one another's (partner effect) weight-status across time using the actor-partner interdependence model.Results
Actor paths were significant over time for parent and child. Partner paths were significant for child zBMI predicting parent BMI at 4 and 12 months. Maintenance condition moderated actor/partner paths in the model.Conclusions
Child weight change may motivate parents to make environmental and behavioural changes that impact their own weight.Trial registration

Project description:The primary objective was to determine whether children and their participating parents undergoing family-based behavioral treatment (FBT) for obesity show similar dietary changes following treatment, and if so, whether these shared dietary changes explain the similarity in weight change within the parent-child dyad.Data come from a randomized controlled trial of 148 parent-child dyads who completed FBT and were followed over a 2-year maintenance phase. Energy-dense, nutrient-poor foods ("RED" foods) and fruit and vegetable intake were assessed across time.Maintenance of lower RED food intake following FBT predicted weight maintenance in children and in parents (ps < .01), and dietary and weight changes were correlated within parent-child dyads (ps < .01). Most interesting, the similarity in long-term weight maintenance between children and their parents was predicted by the similarity in long-term changes in RED food intake between children and their parents (p < .001).These findings point to the important role of maintaining low energy-dense, nutrient-poor food intake for long-term weight maintenance in children and parents. Furthermore, these results suggest that the correlation between parent and child weight maintenance can be explained in part by similar long-term changes in energy-dense, nutrient-poor food intake.

Project description:BackgroundThere are two alternative mechanisms, elucidating the reciprocal relationship between self-efficacy and social support when explaining health outcomes: self-efficacy beliefs may operate as the establisher of social support (the cultivation model) or social support may enable the formation of self-efficacy beliefs (the enabling model).PurposeIn line with the cultivation hypothesis, it was tested if self-efficacy (measured in parents and children) would indirectly predict parental and child moderate-to-vigorous physical activity (MVPA), via the mediator, social support (parent-provided, child-received). In line with the enabling hypothesis, it was tested if social support would predict MVPA indirectly, via the mediator, self-efficacy.MethodsA total of 879 parent-child dyads (1758 individuals; 52.4% girls, aged 5-11 years old, 83.2% mothers) provided self-reports at the baseline (T1) and the 7- to 8-month follow-up (T2). Body weight and height were measured objectively. Manifest path analyses were performed, controlling for the baseline levels of the mediator and dependent variables.ResultsA similar number of significant simple indirect effects was found for the cultivation and the enabling model. Across the models, the indirect effects followed similar patterns: (a) within-individual indirect effects in children; (b) across-individual indirect effects, with the independent variable measured in children and the mediator/dependent variables measured in parents (e.g., child self-efficacy predicted parental support provision and, indirectly, parental MVPA); (c) across-individual indirect effects, accounting for self-efficacy and MVPA measured in children, combined with parental reports of social support.ConclusionsThe findings provide support for both cultivation and enabling models in the context of MVPA among parent-child dyads.

Project description:The biological mechanisms involved in fear transmission within families have been scarcely investigated in humans. Here we studied (1) how children acquired conditioned fear from observing their parent, or a stranger, being exposed to a fear conditioning paradigm, and (2) the subsequent fear extinction process in these children. Eighty-three child-parent dyads were recruited. The parent was filmed while undergoing a conditioning procedure where one cue was paired with a shock (CS + Parent) and one was not (CS -). Children (8 to 12 years old) watched this video and a video of an adult stranger who underwent conditioning with a different cue reinforced (CS + Stranger). Children were then exposed to all cues (no shocks were delivered) while skin conductance responses (SCR) were recorded. Children exhibited higher SCR to the CS + Parent and CS + Stranger relative to the CS -. Physiological synchronization between the child's SCR during observational learning and the parent's SCR during the actual process of fear conditioning predicted higher SCR for the child to the CS + Parent. Our data suggest that children acquire fear vicariously and this can be measured physiologically. These data lay the foundation to examine observational fear learning mechanisms that might contribute to fear and anxiety disorders transmission in clinically affected families.

Project description:It is unclear the role of salient psychosocial variables, such as physical activity (PA) enjoyment and self-efficacy, has on PA within parent-adolescent dyads. The purpose of this study was to examine the interdependent relationships among enjoyment, efficacy, and self-reported PA within parent-adolescent dyads using the Actor-Partner Interdependence Model (APIM). The sample consisted of 1854 parent-adolescent dyads enrolled in the Family Life, Activity, Sun, Health, and Eating (FLASHE) Study. A panel research organization invited panel members balanced to the US population on sex, Census division, household income and size, and race/ethnicity. Panel members were screened for eligibility and web-based surveys were administered to each selected parent-adolescent dyad. Each individual answered questions pertaining to PA enjoyment, PA self-efficacy, and reported weekly PA using validated questionnaires. Interrelationships among the observed variables were analyzed using APIM via a partially recursive path analysis. There was a significant correlation between parent and adolescent PA (r?=?0.15, p?<?0.001). Psychosocial variables explained more variance in adolescent PA (R2?=?0.252) than parent PA (R2?=?0.037) and the strongest standardized path coefficients were adolescent enjoyment (b?=?0.24; 95%CI: 0.18-0.29; p?<?0.001) and self-efficacy (b?=?0.27; 95%CI: 0.22-0.32; p?<?0.001) predicting adolescent PA. Adolescent- and parent-driven effects (0.7%-6.5%) and actor-driven effects (3.3%-5.7%) explained the majority of the systematic dyadic covariance in self-reported PA. There is a relatively strong association between adolescent enjoyment and self-efficacy with adolescent PA and the relationship between parent and adolescent self-reported PA is partially explained by parent and adolescent psychosocial variables and actor-driven effects within APIM.

Project description:The parent-child relationship is a cornerstone of early childhood development and one-way early childhood programs can have a positive influence on early development is to adopt programmatic features to enhance this relationship. Research supports these conclusions in both U.S. and cross-cultural contexts, even though assumptions about parenting and the parent-child relationship may differ across cultures. However, for true understanding of cultural differences, it is important to have comparable measures across cultures. The purpose of the study is to assess measurement invariance of the two constructs of the Child-parent Relationship Scale using data gathered in programs serving low-income preschool children in the U.S.(n = 4,450) and Turkey (n = 592) from 2014 to 2015. Using Single-group Confirmatory Factor Analysis, the original factor structures of the Turkish and the English versions were tested. Besides, Multigroup Confirmatory Factor Analysis provided evidence for configural, metric, scalar invariance, strict factorial invariance or error variance invariance and construct level invariance across the two versions. Only configural invariance was established, which showed an agreement for the existence of an underlying theoretical construct for each subscale (Conflict and Closeness) of the Turkish and the English versions. However, item CPRS 4 was a non-significant item for Conflict in the Turkish version that affected the possibility to conduct further analyses. Findings encourage researchers to propose and assess cultural and linguistic adaptations for the Child-parent Relationship Scale before cross-cultural comparisons related to family relationships.

Project description:Triad families are routinely used to test association between genetic variants and complex diseases. Triad studies are important and popular since they are robust in terms of being less prone to false positives due to population structure. In practice, one may collect not only complete triads, but also incomplete families such as dyads (affected child with one parent) and singleton monads (affected child without parents). Since there is a lack of convenient algorithms and software to analyze the incomplete data, dyads and monads are usually discarded. This may lead to loss of power and insufficient utilization of genetic information in a study.We develop likelihood-based statistical models and likelihood ratio tests to test for association between complex diseases and genetic markers by using combinations of full triads, parent-child dyads, and affected singleton monads for a unified analysis. A likelihood is calculated directly to facilitate the data analysis without imputation and to avoid computational complexity. This makes it easy to implement the models and to explain the results.By simulation studies, we show that the proposed models and tests are very robust in terms of accurately controlling type I error evaluations, and are powerful by empirical power evaluations. The methods are applied to test for association between transforming growth factor alpha (TGFA) gene and cleft palate in an Irish study.

Project description:ObjectiveAlthough there is substantial evidence corroborating the within-individual associations between depression, social support, moderate-to-vigorous physical activity (MVPA), and body mass, much less is known about across-individual associations. This study investigated the indirect associations between parental depression and objectively measured body mass in children. In particular, it was hypothesized that higher levels of parental depression (measured at Time 1, T1) would explain higher levels of child body mass in children (assessed at Time 2, T2), via three mediators, namely parental reports of provision of MVPA support (T1), child reports of receipt of MVPA support (T1), and child MVPA (T2).DesignParent-child dyads provided self-reports twice, at baseline (T1) and 7- to 8-month follow-up (T2). A total of 879 dyads were enrolled (1,758 individuals; 5- to 11-year-old children, 52.4% girls, 83.2% mothers). Body weight and height were measured objectively. Manifest path analyses were performed to test the indirect effects.ResultsAnalyses corroborated the assumed indirect effects: high levels of depression in parents (T1) were indirectly associated with high levels of body mass in children (T2), via three mediators: low levels of parental support provision (T1), low levels of child support receipt (T1), and low levels of child MVPA (T2). The alternative models assuming that either parental support provision or child support receipt can be excluded as the mediators yelded a poor model-data fit. The hypothesized mediation effects were corroborated when controlling for the baseline levels of parental and child MVPA and body mass.ConclusionThe findings confirm complex across-individual effects of parental depression on high levels of body mass in children. Parental mental health may contribute to the childhood obesity epidemic.

Project description:BACKGROUND:Children's food preference and intake patterns are affected by parental child feeding practices. The objective was to determine patterns of food parenting practices regarding junk food and sugary drinks (JS) and investigate their associations with demographic characteristics and dietary intake in a large cohort of parents and their children (12-17?years). METHODS:Dyadic survey data from the cross-sectional, internet-based Family Life, Activity, Sun, Health, and Eating Study, conducted in 2014, were analyzed using latent class analysis to identify patterns of use for six JS parenting practices - negative emotions, restriction, monitoring, availability, modeling, and child involvement - based on parent and child report. Model covariates included self-reported parent and child sex, age (child only), body mass index category (based on height and weight), added sugars intake, and legitimacy of parental authority. RESULTS:Based on 1657 parent-child dyads, five parenting practice patterns were identified representing different levels of practice use - Complete Influencers (28%; reference class), Indifferent Influencers (21%), Negative Influencers (20%), Minimal Influencers (18%), and Disagreeing Influencers (13%). Compared to older child dyads, younger child dyads were less likely to belong to Indifferent and Minimal Influencers (79 and 63% lower odds, respectively). Greater parent added sugars intake increased the odds of belonging to Indifferent and Negative Influencers (4 and 5% higher for every teaspoon increase, respectively) while greater child added sugars intake decreased the odds of belonging to Minimal Influencers (6% lower for every teaspoon increase). Compared to dyads with high scores, dyads with low child scores for legitimacy of parental authority regarding JS were 18 times as likely to belong to Disagreeing Influencers. CONCLUSIONS:The study findings suggest that parents utilize distinct patterns of feeding practices regarding JS ranging from use of many practices, use of some practices, to low use of any practice, with differential associations with parent and child intakes of added sugars. Counseling or intervening with parents to use a mix of structure practices, such as availability and modeling, to positively influence their child's and possibly their own intake of sugary snacks and drinks may prove more efficacious than use of coercive control practices, such as negative emotions.

Project description:ObjectivesMulti-actor data show that parents' and adult children's evaluations of their relation do not necessarily match. We studied disagreement in parent- and child-reported closeness, comparing parent-child dyads involving separated parents, non-separated parents, and stepparents to shed new light on today's diverse landscape of adult parent-child relations.MethodUsing data from the Parents and Children in the Netherlands (OKiN) survey, we analyzed closeness in parent-child dyads (N = 4,602) comparing (step)parents' and their adult children's (aged 25-45) reports. To distinguish directional disagreement (i.e., differences in child- and parent-reported means) from nondirectional disagreement (i.e., the association between child- and parent-reported measures), while accounting for absolute levels of closeness, we estimated log-linear models.ResultsAll types of parents tend to report higher levels of closeness than their children. Whereas parental overreport is more prevalent among biological father-child dyads than among biological mother-child dyads, we found no differences between biological dyads and stepdyads. The association between children's and parents' reports is higher among dyads involving stepmothers or married mothers than among those involving separated mothers and (step)fathers.DiscussionThe intergenerational stake (i.e., parental overreport) is not unique to biological parent-child relations. Instead, patterns of disagreement seem most strongly stratified by gender.

Project description:The Weight Loss Maintenance Trial tested strategies for maintenance of weight loss. Personal contact was superior to interactive technology and self-directed conditions.We aimed to identify behavioral mediators of the superior effect of personal contact vs. interactive technology and of personal contact vs. self-directed arms.Overweight/obese adults at risk for cardiovascular disease (n?=?1,032) who lost at least 4 kg were randomized to personal contact, interactive technology, or self-directed. After 30 months, 880 participants had data on weight and behavioral strategies.Reported increase of intake of fruits and vegetables and physical activity and more frequent self-weighing met criteria as mediators of the better outcome of personal contact vs. interactive technology. Increased intake of fruits and vegetables, more frequent self-weighing, and decreased dessert consumption were mediators of the difference between personal contact vs. self-directed.Inducing changes in the identified behaviors might yield better outcomes in future weight loss maintenance trials.
