Parents of intersex children are perceived in many studies as hopeless, highly dependent on the medical system, and as gate keepers of normative gendered bodies. In this article, we challenge these perceptions and argue that parents of intersex children are problematically positioned between their children's needs for care and well-being and the socialmedical forces that aim to "normalize" them. Their in-between position leads them to establish different parental strategies within and outside of traditional sex/gender norms. We focus on three intertwined parental strategy frameworks: bodily dialogue, sex/gender framing, and concealing/revealing practices, and describe how, in each of these strategic frameworks, the parents maneuver, act in accordance with or against, react to, and challenge the medical system, social interactions, and the sex/gender paradigm. This is a comparative study based on narrative interviews with 22 parents of intersex children in Germany and Israel.

This study investigated the effects of two parental socio-economic characteristics, education and income, on growth and risk of obesity in children from birth to 8 years of age. Longitudinal growth data and national register-based information on socio-economic characteristics were available for 3,030 Swedish children. The development of body mass index (BMI) and height was compared in groups dichotomised by parental education and income. Low parental education was associated with a higher BMI from 4 years of age, independent of income, immigrant background, maternal BMI and smoking during pregnancy. Low family income was associated with a lower birthweight, but did not independently predict BMI development. At 8 years of age, children from less educated families had a three times higher risk of obesity, independent of parental income. Children whose parents had fewer years of education but high income had significantly higher height than all other children. Parental education protected against childhood obesity, even after adjusting for income and other important parental characteristics. Income-related differences in height, despite similar BMIs, raise questions about body composition and metabolic risk profiles. The dominant role of education underscores the value of health literacy initiatives for the parents of young children. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

This investigation examines self-perception and parental perception of child body size and factors associated with accurate parental perception of child body size. Latino at-risk for overweight (AROW) and/or overweight preadolescent children (ages 8-11 years) along with their parents were recruited (N=123 dyads). Children's body mass index (BMI) was measured but not discussed before participants were shown pictures of body sizes and asked to select the image that represented the child's body. The correlation between the child's body size selection and the child's actual BMI was 0.117 (p=0.20) whereas the correlation between the parent's assessment of the child's body size and the child's actual BMI was 0.470 (p<0.001). Logistic regression revealed that only parental education level (> or =college) was associated with a more accurate parental perception of their child's body size (OR: 0.11/95% CI: 0.01, 0.89) while child's sex, parental BMI, and parental health status were not associated with a perception that corresponded to the child's BMI. The sample was drawn from a single community clinic in Forsyth County which serves a large population of newer Latino immigrants in the county. The results indicate that (1) Latino AROW/overweight preadolescent children do not have an accurate perception of their own body size; (2) Latino parents have a more accurate perception of their child's body size with a moderately sized correlation suggesting that their perception of their child's body size is frequently inaccurate; and (3) Latino parents with higher education perceive their child's body size more accurately than less educated parents.

To investigate differences in the association of parental history of diabetes with the risk of type 2 diabetes mellitus (T2DM) in the offspring according to the sex of the parent and the offspring's body weight. A prospective cohort study of 4446 middle-aged non-diabetic Japanese men and women were followed in Aichi Prefecture, central Japan, from 2002 to 2011. Subjects were categorized by their self-reported parental history of diabetes ("no parental history," "father only," "mother only," and "both"). The association of parental history of diabetes and incidence in the offspring was examined according to overweight status adjusted for age, sex, birth weight, smoking, alcohol consumption, physical activity, total energy intake, body mass index, and number of metabolic syndrome components. During follow-up (median 8.9 years), 277 subjects developed T2DM. Parental history of diabetes was positively associated with T2DM incidence. However, stratified analysis by overweight status revealed that only maternal history was associated with increased T2DM incidence in non-overweight subjects (hazard ratio=2.35, 95% confidence interval: 1.41-3.91). While in overweight subjects, paternal history was significantly associated with higher T2DM incidence (hazard ratio=1.98, 95% confidence interval: 1.19-3.28). Our results suggest that parental history of diabetes mellitus is associated with the incidence of T2DM in offspring differently according to the sex of the affected parent and the offspring's body weight.

Mothers are a key influence on adolescent girls' body image. This study aimed to improve understanding of mothers' and daughters' preferences for content in body image interventions designed to assist mothers to promote positive body image among their daughters. British mother-daughter dyads (N=190) viewed descriptions of five evidence-based influences on body image (family, friends, and relationships; appearance-based teasing; media and celebrities; appearance conversations; body acceptance and care). Mothers and daughters each selected the two most important influences to learn about in these interventions. Overall, both mothers and daughters most frequently opted for family, friends, and relationships and body acceptance and care, whereas media and celebrities was their least preferred topic. While the overall sample of mothers and daughters agreed on preferences, Fisher's exact tests showed that within-dyad agreement was low. Recommendations for improving parent and child engagement with, and effectiveness of, child body image interventions delivered to parents are discussed. Copyright © 2016 Elsevier Ltd.

Few authors have evaluated sports injury-surveillance systems that use parental, Internet-based surveys for data collection. To determine whether certified athletic trainers (ATs) and parental, Internet-based surveys provided comparable data for identifying soccer injuries. Prospective feasibility cohort study. A soccer association in Seattle, Washington. Eighty female youth soccer players, ages 12 to 14 years. We compared the data provided by ATs attending 1 soccer practice per week with a weekly soccer-parent, Internet-based system. We measured athlete-exposure hours (AEHs) for each player. We compared injury rates reported by ATs only, Internet-based surveys only, and both systems combined. We evaluated the 2 surveillance systems for agreement on injured body region and laterality of injury using the kappa statistic. For ATs only, Internet-based surveys only, and both systems combined, we found acute injury rates of 3.0 per 1000 AEHs, 3.9 per 1000 AEHs, and 4.7 per 1000 AEHs and overuse injury rates of 1.0 per 1000 AEHs, 2.9 per 1000 AEHs, and 2.9 per 1000 AEHs, respectively. Players sustained 27 acute injuries (44% ankle, 11% knee, 11% hip) reported by at least 1 of the 2 systems, with 63% reported by ATs and 85% by Internet-based survey. Players sustained 17 overuse injuries (35% knee, 29% lower leg) reported by either system, with 35% reported by ATs and 100% by Internet-based survey. Among players for whom we had both ATs' and Internet-based survey injury data, body region injured and laterality had very good agreement (kappa = 0.73 to 1.0). The injury rate based on the weekly parental, Internet-based survey was similar to the rate based on the ATs' reporting and had comparable classifications of injured body region and laterality of injury.

The Dawn spacecraft targeted 4 Vesta, believed to be a remnant intact protoplanet from the earliest epoch of solar system formation, based on analyses of howardite-eucrite-diogenite (HED) meteorites that indicate a differentiated parent body. Dawn observations reveal a giant basin at Vesta's south pole, whose excavation was sufficient to produce Vesta-family asteroids (Vestoids) and HED meteorites. The spatially resolved mineralogy of the surface reflects the composition of the HED meteorites, confirming the formation of Vesta's crust by melting of a chondritic parent body. Vesta's mass, volume, and gravitational field are consistent with a core having an average radius of 107 to 113 kilometers, indicating sufficient internal melting to segregate iron. Dawn's results confirm predictions that Vesta differentiated and support its identification as the parent body of the HEDs.

The longitudinal causal directionality between body image distress and self-esteem among Korean adolescents: the moderating effect of relationships with parents.

This study examined the longitudinal relationship between self-esteem and body image distress, as well as the moderating effect of relationships with parents, among adolescents in Korea, using nationally representative prospective panel data. Regarding causal direction, the findings supported bi-directionality for girls, but for boys the association was unidirectional, in that their self-esteem predicted body image distress, but not vice versa. A gender difference also emerged in the moderating effect of quality of relationships with parents. For girls, relationships with parents moderated the effect of body image distress on self-esteem, such that when relationships with parents were better, the effect of greater body image distress on subsequent lower self-esteem was stronger than when relationships with parents were less positive. For boys, relationships with parents moderated the influence of self-esteem on body image distress, such that self-esteem reduced body image distress more when boys had better relationships with parents.

The development of an unrealistic ideal body image and body size dissatisfaction among children is common in Western countries, including the USA and many European nations. However, little is known about children's body image perceptions in post-communist countries. This pilot study evaluated body image perceptions in a sample of Czech school-aged children and their parents and compared them with the perceptions of American children and parents. Ninety-seven Czech and 45 American 4th-6th graders and their parents from eight urban schools participated in this study. A previously developed silhouette body image instrument was utilized in a parent questionnaire and during child interviews to measure perceived and ideal body image perceptions of children and parents. Descriptive statistics, independent t-tests and paired t-tests were used to compare differences between children's and parents' perceived and ideal body image perceptions. Associations between body image perceptions and other variables were explored using bivariate correlations. American children had a thinner ideal body image compared with Czech children (P < 0.05). However, a larger proportion of Czech boys desired to be thinner compared with American boys (34.2% vs. 20%). Parent's ideal body image for their children did not differ by nationality (P = 0.858). While the pressure on children to look thinner was apparent among both American and Czech children, Czech children considered a larger body size as more ideal. A future study should evaluate body image perceptions and factors influencing these perceptions in a representative sample of Czech children and parents.

Parental perceptions of weight terminology that providers use with youth.

Little research has been performed to examine patient perceptions of weight-related language, especially related to childhood obesity. In this study we assessed parental perceptions of weight-based terminology used by health care providers to describe a child's excess weight and assessed perceived connotations associated with these terms including stigma, blame, and motivation to reduce weight. A national sample of American parents with children aged 2 to 18 years (N = 445) completed an online survey to assess their perceptions of 10 common terms to describe excess body weight in youth (including "extremely obese," "high BMI," "weight problem," "unhealthy weight," "weight," "heavy," "obese," "overweight," "chubby," and "fat"). Parents were asked to use a 5-point rating scale to indicate how much they perceived each term to be desirable, stigmatizing, blaming, or motivating to lose weight. Regression models revealed that the terms "weight" and "unhealthy weight" were rated as most desirable, and "unhealthy weight" and "weight problem" were rated as the most motivating to lose weight. The terms "fat," "obese," and "extremely obese" were rated as the most undesirable, stigmatizing, blaming, and least motivating. Parents' ratings were consistent across sociodemographic variables, body weight, and child's body weight. The results of this study have important implications for the improvement of health care for youth with obesity; it may be advantageous for health care providers to use or avoid using specific weight-based language during discussions about body weight with families. Pediatricians play a key role in obesity prevention and treatment, but their efforts may be undermined by stigmatizing or offensive language that can hinder important discussions about children's health.

A lot of publications emphasize the special role of parents' eating habits and their lifestyle on the prevalence of excess body weight in children. The aim of this study was to answer the question whether parents of children who are overweight and obese are aware of this problem and what factors affect their perception of the excess body weight degree in their offspring. The study included 137 children aged 6,5- 13,5 years. 23 respondents were overweight and 76 obese. Compared group consisted of 113 children. All patients underwent physical examination with anthropometric measurements. Parents were asked to complete a questionnaire, where they evaluated the degree of excess body weight of their child. We also asked about both parents' weight and body height, their education and chronic diseases occurring in the family. In the group of obese children 56.2% of the respondents came from families where one parent had excess body weight while 32.9% of them from families where this problem affected both parents. In 51.3% of patients with a body mass index (BMI) above 95 centil, parents wrongly assessed the degree of excess body weight of their child, in overweight group this proportion accounted for 8.7%. There was a statistically significant (p = 0.007) correlation between the degree of children's excess body weight and the ability of parents to estimate that. Parents' education had no influence on the incidence of excess body weight in children and their ability to determine its extent. In the group of obese and overweight children only 4% of parents recognized obesity as a chronic disease. Parents of children who are overweight and obese have lower awareness about their child's weight in comparison to parents of children with normal weight. There is a statistical correlation between parents' perception of excess body weight and the development of obesity in children. © 2015 MEDPRESS.

Family-based weight loss treatment (FBT) is considered the gold-standard treatment for childhood obesity and is provided to the parent and child. However, parent-based treatment (PBT), which is provided to the parent without the child, could be similarly effective and easier to disseminate. To determine whether PBT is similarly effective as FBT on child weight loss over 24 months. Secondary aims evaluated the effect of these 2 treatments on parent weight loss, child and parent dietary intake, child and parent physical activity, parenting style, and parent feeding behaviors. Randomized 2-arm noninferiority trial conducted at an academic medical center, University of California, San Diego, between July 2011 and July 2015. Participants included 150 overweight and obese 8- to 12-year-old children and their parents. Both PBT and FBT were delivered in 20 one-hour group meetings with 30-minute individualized behavioral coaching sessions over 6 months. Treatments were similar in content; the only difference was the attendance of the child. The primary outcome measure was child weight loss (body mass index [BMI] and BMI z score) at 6, 12, and 18 months post treatment. Secondary outcomes were parent weight loss (BMI), child and parent energy intake, child and parent physical activity (moderate to vigorous physical activity minutes), parenting style, and parent feeding behaviors. One hundred fifty children (mean BMI, 26.4; mean BMI z score, 2.0; mean age, 10.4 years; 66.4% girls) and their parent (mean BMI, 31.9; mean age, 42.9 years; 87.3% women; and 31% Hispanic, 49% non-Hispanic white, and 20% other race/ethnicity) were randomly assigned to either FBT or PBT. Child weight loss after 6 months was -0.25 BMI z scores in both PBT and FBT. Intention-to-treat analysis using mixed linear models showed that PBT was noninferior to FBT on all outcomes at 6-, 12-, and 18-month follow-up with a mean difference in child weight loss of 0.001 (95% CI, -0.06 to 0.06). Parent-based treatment was as effective on child weight loss and several secondary outcomes (parent weight loss, parent and child energy intake, and parent and child physical activity). Parent-based treatment is a viable model to provide weight loss treatment to children. Clinicaltrials.gov Identifier: NCT01197443.

Background Few studies have examined parent-child resemblance in body weight status using nationally representative data for the US. Design We analyzed Body Mass Index (BMI), weight status, and related correlates for 4,846 boys, 4,725 girls, and their parents based on US nationally representative data from the 2006 and 2007 Medical Expenditure Panel Survey (MEPS). Pearson partial correlation coefficients, percent agreement, weighted kappa coefficients, and binary and multinomial logistic regression were used to examine parent-child resemblance, adjusted for complex sampling design. Results Pearson partial correlation coefficients between parent and child’s BMI measures were 0.15 for father-son pairs, 0.17 for father-daughter pairs, 0.20 for mother-son pairs, and 0.23 for mother-daughter pairs. The weighted kappa coefficients between BMI quintiles of parent and child ranged from −0.02 to 0.25. Odds ratio analyses found children were 2.1 (95% confidence interval (CI): 1.6, 2.8) times more likely to be obese if only their father was obese, 1.9 (95% CI: 1.5, 2.4) times more likely if only their mother was obese, and 3.2 (95% CI: 2.5, 4.2) times more likely if both parents were obese. Conclusions Parent-child resemblance in BMI appears weak and may vary across parent-child dyad types in the US population. However, parental obesity status is associated with children’s obesity status. Use of different measures of parent-child resemblance in body weight status can lead to different conclusions.

Long-lived magnetism on chondrite parent bodies

We present evidence for both early- and late-stage magnetic activity on the CV and L/LL parent bodies respectively from chondrules in Vigarano and Bjurböle. Using micro-CT scans to re-orientate chondrules to their in-situ positions, we present a new micron-scale protocol for the paleomagnetic conglomerate test. The paleomagnetic conglomerate test determines at 95% confidence, whether clasts within a conglomerate were magnetized before or after agglomeration, i.e., for a chondritic meteorite whether the chondrules carry a pre- or post-accretionary remanent magnetization. We found both meteorites passed the conglomerate test, i.e., the chondrules had randomly orientated magnetizations. Vigarano's heterogeneous magnetization is likely of shock origin, due to the 10 to 20 GPa impacts that brecciated its precursor material on the parent body and transported it to re-accrete as the Vigarano breccia. The magnetization was likely acquired during the break-up of the original body, indicating a CV parent body dynamo was active ∼9 Ma after Solar System formation. Bjurböle's magnetization is due to tetrataenite, which transformed from taenite as the parent body cooled to below 320 °C, when an ambient magnetic field imparted a remanence. We argue either the high intrinsic anisotropy of tetrataenite or brecciation on the parent body manifests as a randomly orientated distribution, and a L/LL parent body dynamo must have been active at least 80 to 140 Ma after peak metamorphism. Primitive chondrites did not originate from entirely primitive, never molten and/or differentiated parent bodies. Primitive chondrite parent bodies consisted of a differentiated interior sustaining a long-lived magnetic dynamo, encrusted by a layer of incrementally accreted primitive meteoritic material. The different ages of carbonaceous and ordinary chondrite parent bodies might indicate a general difference between carbonaceous and ordinary chondrite parent bodies, and/or formation location in the protoplanetary disk.

Objectives To examine whether changes in parent motivation over the course of a pediatric obesity intervention are significantly associated with long-term changes in treatment outcomes. Methods Study hypotheses were tested with a secondary data analysis of a randomized controlled trial (N = 42). Study analyses tested whether baseline to posttreatment change in total score for a self-report parent motivation measure (Parent Motivation Inventory [PMI]) was significantly associated with baseline to 6-month follow-up changes in body mass index z-score (zBMI), dietary variables, and physical activity. Results Increases in PMI were significantly associated with decreased zBMI, decreased consumption of sugar-sweetened beverages and sweets, and increased consumption of artificially sweetened beverages. Conclusions Given that increases in parent motivation were associated with some treatment benefits, future research should evaluate the impact of directly assessing and targeting parent motivation on weight outcomes for preschoolers participating in a weight management program.

2017-04-01

School-based body mass index screenings (SBMIS) have been controversial. We aimed to determine if parents would indicate improved utility with SBMIS when the report included parent education and whether parental intent to modify obesity risk factors would vary with report type or child weight. A cluster-controlled trial was conducted with 31 elementary schools randomized to distribute a standard SBMIS report or the standard report plus education (SBMIS+). A random subsample of parents completed a mailed survey (731 SBMIS, 738 SBMIS+). Using a two-stage cluster sampling design, logistic regression models with school-level random effect were used to assess differences between conditions and by weight category. Parents in the SBMIS+ condition vs. the standard condition were more likely to indicate that the report provided useful information (not significant) and an intent to help their child get enough sleep (p < 0.001). Parents of children who were overweight or obese were less likely than parents of children who were not to indicate that the report provided useful information about their child's weight status (p < 0.001) or access to resources (p < 0.05). However, these parents were more likely to plan a visit to healthcare provider (p < 0.001) and to intend to limit sugar-sweetened beverages (p < 0.05). Parental education can enhance the utility of the SBMIS report and parental intention to modify at least one obesity risk factor. SBMIS reports prompted parents of children with overweight and obesity to seek clinical care and limit sugar-sweetened drinks.

A prospective study on the impact of peer and parental pressure on body dissatisfaction in adolescent girls and boys.

2011-03-01

The current study explores the role of appearance-related social pressure regarding changes in body image in adolescent girls (n=236) and boys (n=193) over a 1-year-period. High school students aged 11-16 completed measures of body dissatisfaction (i.e., weight and muscle concerns) and appearance-related social pressure from peers and parents. Three aspects proved to be particularly crucial: Parental encouragement to control weight and shape was a strong predictor of weight concerns in boys and girls alike; influences of friends affected gender-specific body image concerns by leading to weight concerns in girls and muscle concerns in boys; finally appearance-based exclusion was a predictor of weight concerns in boys. The findings provide longitudinal evidence for the crucial impact of appearance-related social pressure and suggest that a detailed assessment of different types of social impacts can identify concrete targets for effective prevention and therapy for weight-related problems among adolescents.

To determine what factors drive participation in a family-based weight management program for 4- to 8-year-old children following screening for overweight or obesity. Children (n = 1093) attended a comprehensive screening appointment where parents completed questionnaires on demographics, motivation for healthy lifestyles, feeding practices, and beliefs about child size, prior to feedback about the child's weight. Parents of overweight or obese children (body mass index ≥85th percentile) attended a follow-up interview to assess reactions to feedback and willingness to participate in a 2-year intervention. A total of 271 (24.8%) children were overweight or obese with 197 (72.7%) agreeing to the intervention. Socioeconomic status differed in intervention participants (n = 197) compared with non-participants (n = 74), whereas no differences were observed in parental feeding practices, ineffective parenting practices, or self-determined forms of motivation. However, fewer non-participating parents believed their child to be overweight (23% vs 49%, P < .001) or were concerned about it (16% vs 43%, P < .001), despite children having an average body mass index approximating the 95th percentile. Non-participating parents did not expect their child to be overweight (P = .002) and rated receiving this information as less useful (P = .008) than participating parents. Preconceptions about child weight and reactions to feedback determined intervention uptake more than parenting or motivation for health. Many parents agreed to participate in the intervention despite not viewing their child as overweight. Copyright © 2013 Mosby, Inc. All rights reserved.

To investigate the interactions between low parental warmth and monitoring at age 13-14 years and disordered eating attitudes and behaviours at age 15-16 years. Data on 1300 (667 females) adolescents and their parents were drawn from The Australian Temperament Project (ATP), a 30 year (15 wave) population based longitudinal study of social-emotional development. Parent participants completed surveys on parenting practices in late childhood, and adolescent participants reported disordered eating using the drive for thinness and bulimia subscales of the Eating Disorder Inventory (EDI) and an additional body dissatisfaction scale. Interaction was examined on the additive scale by estimating super-additive risk; i.e., risk in excess of the sum of individual risks. For boys, neither parental warmth or monitoring, nor their interaction, was related to disordered eating. For girls, low parental warmth (alone) was associated with bulimic behaviours. In contrast, exposure to both low monitoring and warmth was associated with ∼3½-fold, ∼4-fold and ∼5-fold increases in the odds of reporting body dissatisfaction, drive for thinness and bulimia, respectively. For body dissatisfaction and drive for thinness, risk associated with joint exposure exceeded the sum of individual risks, suggesting an additive interaction between parenting styles. Further investment in family-level interventions that focus on promoting parental monitoring behaviour and a warm parent-child relationship remain important strategies for preventing a range of disordered eating behaviours in adolescents.

The aim of this study was to test the feasibility and accuracy of a smartphone application to measure the body length of children using the integrated camera and to evaluate the subsequent weight estimates. A prospective clinical trial of children aged 0-<13 years admitted to the emergency department of the University Children's Hospital Zurich. The primary outcome was to validate the length measurement by the smartphone application «Optisizer». The secondary outcome was to correlate the virtually calculated ordinal categories based on the length measured by the app to the categories based on the real length. The third and independent outcome was the comparison of the different weight estimations by physicians, nurses, parents and the app. For all 627 children, the Bland Altman analysis showed a bias of -0.1% (95% CI -0.3-0.2%) comparing real length and length measured by the app. Ordinal categories of real length were in excellent agreement with categories virtually calculated based upon app length (kappa = 0.83, 95% CI 0.79-0.86). Children's real weight was underestimated by physicians (-3.3, 95% CI -4.4 to -2.2%, p < 0.001), nurses (-2.6, 95% CI -3.8 to -1.5%, p < 0.001) and parents (-1.3, 95% CI -1.9 to -0.6%, p < 0.001) but overestimated by categories based upon app length (1.6, 95% CI 0.3-2.8%, p = 0.02) and categories based upon real length (2.3, 95% CI 1.1-3.5%, p < 0.001). Absolute weight differences were lowest, if estimated by the parents (5.4, 95% CI 4.9-5.9%, p < 0.001). This study showed the accuracy of length measurement of children by a smartphone application: body length determined by the smartphone application is in good agreement with the real patient length. Ordinal length categories derived from app-measured length are in excellent agreement with the ordinal length categories based upon the real patient length. The body weight estimations based upon length corresponded to known data and limitations. Precision of body weight estimations by paediatric physicians and nurses were comparable and not different to length based estimations. In this non-emergency setting, parental weight estimation was significantly better than all other means of estimation (paediatric physicians and nurses, length based estimations) in terms of precision and absolute difference.

The discrepancies between parents and their children on the description of the behavior and representations of their children have been shown in various studies. Other researchers have reported the parents' difficulty in correctly identifying the weight status of their children. The purpose of our study was to investigate the parent's attributional accuracy on their children's body weight perception in relation to the children attachment security. It was hypothesized that insecure children's parents have a greater discrepancy with their children compared to secure children with their parents. The research participants were 217 children, aged between 5 and 11 years of both genders, and their parents. The attachment pattern was measured by the SAT of Klagsbrun and Bowlby, with the Italian version of Attili. The children were also shown a set of figure body-drawings with which to measure the perception of their weight status. Parents answered a questionnaire to find out the parental attribution of their children's perception. The results show that the body weight perception of insecure children's parents have a greater discrepancy with their children's body weight perception compared with parentally secure children. In particular, parents of insecure children tend to underestimate the perception of their children. This result is most evident in disorganized children. In addition, the perception of insecure children's parents show a greater correlation with children's actual weight rather than with their children's perception. These results suggest that the discrepancies on the perception of children's body weight between parents and children may be influenced by the poor parental attunement to their children's internal states, which characterizes the insecure parent-child attachment relationship.

Firstly, to investigate the degree of concern parents feel about their children's weight (parental concern). Secondly, to identify factors that influence this concern, and to test a model of parental concern using structural equation modeling. A total of 347 non-overweight, overweight, and obese children (aged 6-13; Mean = 9.5, SD = 1.8) and their parents. Children and their parents attended an assessment session during which they were weighed and measured. Parents were administered a structured interview, which included the Eating Disorder Examination, and completed the Pediatric Quality of Life Inventory (parent proxy), and the Children's Body Image Scale. Eighty-two percent of parents of overweight children, and 18% of parents of obese children reported little parental concern. Higher parental concern was associated with higher child Body Mass Index, less parental underestimation of child body size, and lower child health-related quality of life. Interventions targeting childhood obesity should aim to optimise parental concern by reducing parents' underestimation of child body size and increasing their awareness of the effects of overweight and obesity on children's health and quality of life.

The objective of this study was to investigate the association of different cognitive abilities with children's body weight adjusted for further weight influencing sociodemographic, family, and lifestyle factors. Cross-sectional data of 498 primary school children (7.0 ± 0.6 years; 49.8% boys) participating in a health promotion programme in southwest Germany were used. Children performed a computer-based test battery (KiTAP) including an inhibitory control task (Go-Nogo paradigm), a cognitive flexibility task, and a sustained attention task. Height and weight were measured in a standardized manner and converted to BMI percentiles based on national standards. Sociodemographic features (migration background and parental education), family characteristics (parental body weight), and children's lifestyle (TV consumption, physical activity, consumption of sugar-sweetened beverages and breakfast habits) were assessed via parental questionnaire. A hierarchical regression analysis revealed inhibitory control and cognitive flexibility to be significant cognitive predictors for children's body weight. There was no association concerning sustained attention. The findings suggest that especially cognitive abilities known as executive functions (inhibitory control and cognitive flexibility) are associated with children's body weight. Future longitudinal and intervention studies are necessary to investigate the directionality of the association and the potential of integrating cognitive training in obesity prevention strategies. This trial is registered with ClinicalTrials.gov DRKS00000494. PMID:25874122

For prospective parents at risk of transmitting a monogenic disease, polar body analysis is an option for pre-conception genetic diagnosis. In Germany, polar body analysis is currently performed in only two centers (Lübeck and Regensburg). The authors present a clinical series of 9 couples at risk for the transmission of a monogenic disease who underwent in vitro fertilization with polar body analysis. Nine couples have undergone in vitro fertilization with polar body analysis at the center in Lübeck since 2004. Three healthy children were born after polar body analysis for mucopolysaccharidosis type I, incontinentia pigmenti, and cystic fibrosis. The decision to undergo in vitro fertilization with polar body analysis is not easy for prospective parents to take, even though it often follows years of emotional suffering. Treatment with the methods of reproductive medicine in general, and with polar body analysis in particular, can cause considerable physical and emotional stress. For prospective parents in Germany at risk of transmitting a monogenic disease, polar body-based preimplantation diagnosis is an alternative to prenatal diagnosis and possible termination of pregnancy. The live birth rate per treatment cycle in this clinical series was 30%, which can be considered satisfactory. Nonetheless, most of the couples who did not achieve pregnancy after a first treatment cycle dropped out of treatment prematurely and did not go on to a second cycle.

Abstract Context: Few authors have evaluated sports injury-surveillance systems that use parental, Internet-based surveys for data collection. Objective: To determine whether certified athletic trainers (ATs) and parental, Internet-based surveys provided comparable data for identifying soccer injuries. Design: Prospective feasibility cohort study. Setting: A soccer association in Seattle, Washington. Patients or Other Participants: Eighty female youth soccer players, ages 12 to 14 years. Main Outcome Measure(s): We compared the data provided by ATs attending 1 soccer practice per week with a weekly soccer-parent, Internet-based system. We measured athlete-exposure hours (AEHs) for each player. We compared injury rates reported by ATs only, Internet-based surveys only, and both systems combined. We evaluated the 2 surveillance systems for agreement on injured body region and laterality of injury using the κ statistic. Results: For ATs only, Internet-based surveys only, and both systems combined, we found acute injury rates of 3.0 per 1000 AEHs, 3.9 per 1000 AEHs, and 4.7 per 1000 AEHs and overuse injury rates of 1.0 per 1000 AEHs, 2.9 per 1000 AEHs, and 2.9 per 1000 AEHs, respectively. Players sustained 27 acute injuries (44% ankle, 11% knee, 11% hip) reported by at least 1 of the 2 systems, with 63% reported by ATs and 85% by Internet-based survey. Players sustained 17 overuse injuries (35% knee, 29% lower leg) reported by either system, with 35% reported by ATs and 100% by Internet-based survey. Among players for whom we had both ATs' and Internet-based survey injury data, body region injured and laterality had very good agreement (κ  =  0.73 to 1.0). Conclusions: The injury rate based on the weekly parental, Internet-based survey was similar to the rate based on the ATs' reporting and had comparable classifications of injured body region and laterality of injury.

Composition and evolution of the eucrite parent body - Evidence from rare earth elements. [extraterrestrial basaltic melts

Consolmagno, G. J.; Drake, M. J.

1977-01-01

Quantitative modeling of the evolution of rare earth element (REE) abundances in the eucrites, which are plagioclase-pigeonite basalt achondrites, indicates that the main group of eucrites (e.g., Juvinas) might have been produced by approximately 10% equilibrium partial melting of a single type of source region with initial REE abundances which were chondritic relative and absolute. Since the age of the eucrites is about equal to that of the solar system, extensive chemical differentiation of the eucrite parent body prior to the formation of eucrites seems unlikely. If homogeneous accretion is assumed, the bulk composition of the eucrite parent body can be estimated; two estimates are provided, representing different hypotheses as to the ratio of metal to olivine in the parent body. Since a large number of differentiated olivine meteorites, which would represent material from the interior of the parent body, have not been detected, the eucrite parent body is thought to be intact. It is suggested that the asteroid 4 Vesta is the eucrite parent body.

Hager, Erin R; McGill, Adrienne E; Black, Maureen M

2010-02-01

The purpose of this study is to develop and validate a toddler silhouette scale. A seven-point scale was developed by an artist based on photographs of 15 toddlers (6 males, 9 females) varying in race/ethnicity and body size, and a list of phenotypic descriptions of toddlers of varying body sizes. Content validity, age-appropriateness, and gender and race/ethnicity neutrality were assessed among 180 pediatric health professionals and 129 parents of toddlers. Inter- and intrarater reliability and concurrent validity were assessed by having 138 pediatric health professionals match the silhouettes with photographs of toddlers. Assessments of content validity revealed that most health professionals (74.6%) and parents of toddlers (63.6%) ordered all seven silhouettes correctly, and interobserver agreement for weight status classification was high (kappa = 0.710, r = 0.827, P < 0.001). Most respondents reported that the scale represented toddlers aged 12-36 months (89%) and was gender (68.5%) and race/ethnicity (77.3%) neutral. The inter-rater reliability, based on matching silhouettes with photographs, was 0.787 (Cronbach's alpha) and the intrarater reliability was 0.855 (P < 0.001). The concurrent validity, based on the correlation between silhouette choice and the weight-for-length percentile of each toddler's photograph, was 0.633 (P < 0.001). In conclusion, a valid and reliable toddler silhouette scale that may be used for male or female toddlers, aged 12-36 months, of varying race/ethnicity was developed and evaluated. This scale may be used clinically or in research settings to assess parents' perception of and satisfaction with their toddler's body size. Interventions can be targeted toward parents who have inaccurate perceptions of or are dissatisfied with their toddler's body size.

There are limited data regarding the associations of both maternal and paternal anthropometrics with longitudinally measured post-natal growth measures in early childhood. To assess the associations of maternal and paternal anthropometrics with growth characteristics and the risk of overweight in pre-school children. Population-based prospective cohort study from early foetal life onwards in the Netherlands. Maternal pre-pregnancy anthropometrics and gestational weight gain, and paternal anthropometrics were related to foetal and post-natal growth measures and the risk of overweight until the age of 4 years. Analyses were based on 5674 mothers, fathers and their children. Both pre-pregnancy maternal and paternal height, weight and body mass index were associated with corresponding foetal and post-natal anthropometric measures. Maternal body mass index had a significantly stronger effect on childhood body mass index than paternal body mass index. As compared to children from parents with normal body mass index, children from two obese parents had an increased risk of overweight at the age of 4 years (odds ratio 6.52 (95% confidence interval 3.44, 12.38). Maternal gestational weight gain was only among mothers with normal body mass index associated with body mass index and the risk of overweight in the children. Maternal and paternal anthropometrics affect early growth in pre-school children differently. Gestational weight gain in mothers without overweight and obesity is related to the risk of overweight in early childhood. © 2012 The Authors.

The study aimed to determine the association between body mass index (BMI)-for-age and health-related quality of life (HRQOL) among high school students in Tehran. A total of 465 high school students (227 girls and 238 boys) and their parents were participated in this cross-sectional study. Body weight and height of the students were measured. For assessing HRQOL, both adolescent self-report and parent proxy-report of the Persian version of Pediatric Quality of Life Inventory (PedsQL™4.0) questionnaire were completed by adolescents and their parents respectively. The prevalence of overweight and obesity (38.5%) was higher than severe thinness and thinness (2.8%). Mean of adolescent self-reported and parent proxy-reported HRQOL total score were 80.26 ± 12.07 and 81.30 ± 14.08 respectively. In terms of HRQOL subscale scores, the highest subscale score of HRQOL was reported in social functioning (87.27 ± 14.40) and the lowest score was reported in emotional functioning (69.83 ± 18.69). Based on adolescent self-report, adolescent boys had significantly higher mean score for total and all subscale scores of HRQOL compared with girls (P < 0.05). BMI-for-age was inversely correlated to adolescent self-reported HRQOL total score (r = -0.25, P < 0.05). Based on adolescents self-report, HRQOL total score was significantly different by body weight status (F = 16.16, P < 0.05). Normal weight adolescents had significantly higher HRQOL total score compared with overweight (mean difference: 7.32; P < 0.05) and obese adolescents (mean difference: 9.10, P < 0.05). The HRQOL total score was not significantly different between normal weight and underweight adolescents (mean difference: 1.65, P = 0.96). However, based on parent proxy-reports, HRQOL total score was not significantly different by body weight status (F = 2.64, P = 0.059). More than one-third of adolescents were overweight and obese. BMI-for-age was inversely correlated to adolescent self-reported HRQOL. Based on adolescents' perspective, overweight and obese adolescents had poorer HRQOL compared with normal weight adolescents. Intervention studies are needed to improve the HRQOL of overweight and obese adolescents in Tehran. © 2013 John Wiley & Sons Ltd.

Adipokines are implicated in the development of obesity-related traits. We hypothesized that nonobese participants without diabetes mellitus (DM) whose parents were obese or had DM would have altered circulating adipokines compared with those without parental history of these conditions. Participants in the community-based Framingham Third Generation cohort who were not obese (body mass index <30) and not diabetic with both parents in the Framingham Offspring cohort were included in this analysis (n=2034, mean age 40 years, 54% women). Circulating concentrations of fetuin A, RBP4 (retinol binding protein 4), FABP4 (fatty acid binding protein 4), leptin, LEP-R (leptin receptor), and adiponectin were assayed. Parental DM was defined as occurring before age 60 years, and obesity was defined as body mass index ≥30 before age 60 years. General estimating equations were used to compare concentrations of adipokines among participants with 0, 1, or 2 parents affected by obesity or DM (separate analyses for each), adjusting for known correlates of adipokines. Overall, 44% had at least 1 parent who was obese and 15% had parents with DM. Parental obesity was associated with higher serum levels of FABP4 and LEP-R in their offspring ( P =0.02 for both). Parental DM was associated with lower adiponectin but higher RBP4 concentrations in offspring ( P ≤0.02 for both). In our community-based sample, a parental history of DM or obesity was associated with an altered adipokine profile in nonobese nondiabetic offspring. Additional studies are warranted to evaluate whether such preclinical biomarker alterations presage future risk of disease. © 2017 The Authors.

Maternal diabetes in pregnancy affects offspring health. The impact of parental diabetes on offspring health is unclear. We investigated the impact of parental diabetes on the metabolic-health of adult-offspring who did not themselves have diabetes. Data from the Generation Scotland: Scottish Family Health Study, a population-based family cohort, were record-linked to subjects’ own diabetes medical records. From F0-parents, we identified F1-offspring of: mothers with diabetes (OMD, n = 409), fathers with diabetes (OFD, n = 468), no parent with diabetes (ONoPD, n = 2489). Metabolic syndrome, body, biochemical measurements and blood-pressures were compared between F1-offspring groups by sex. A higher proportion of female OMD had metabolic syndrome than female OFD or ONoPD (P<0.0001). In female offspring, predictors of metabolic syndrome were: having a mother with diabetes (OR = 1.78, CI 1.03–3.07, [reference ONoPD]), body mass index (BMI, OR = 1.21, CI 1.13–1.30) and age (OR = 1.03, CI 1.01–1.06). In male offspring, predictors of metabolic syndrome were: BMI (OR = 1.18, CI 1.09–1.29) and percent body-fat (OR = 1.12, CI 1.05–1.19). In both sexes, OMD had higher blood-pressures than OFD (P<0.0001). In females, OMD had higher glucose (P<0.0001) and percent body-fat (P<0.0001) compared with OFD or ONoPD. OMD and OFD both had increased waist-measurements (P<0.0001), BMI (P<0.0001) and percent body-fat (P<0.0001) compared with ONoPD. Female OMD and OFD had lower HDL-cholesterol levels (P<0.0001) than female ONoPD. Parental diabetes is associated with higher offspring-BMI and body-fat. In female offspring, maternal diabetes increased the odds of metabolic syndrome, even after adjusting for BMI. Further investigations are required to determine the mechanisms involved. PMID:26308734

Magnetic Evidence for a Partially Differentiated Carbonaceous Chondrite Parent Body and Possible Implications for Asteroid 21 Lutetia

The origin of remanent magnetization in the CV carbonaceous chondrite Allende has been a longstanding mystery. The possibility of a core dynamo like that known for achondrite parent bodies has been discounted because chondrite parent bodies are assumed to be undifferentiated. Here we report that Allende's magnetization was acquired over several million years (Ma) during metasomatism on the parent planetesimal in a > 20 microtesla field 8-9 Ma after solar system formation. This field was present too recently and directionally stable for too long to have been the generated by the protoplanetary disk or young Sun. The field intensity is in the range expected for planetesimal core dynamos (Weiss et al. 2010), suggesting that CV chondrites are derived from the outer, unmelted layer of a partially differentiated body with a convecting metallic core (Elkins-Tanton et al. 2010). This suggests that asteroids with differentiated interiors could be present today but masked under chondritic surfaces. In fact, CV chondrites are spectrally similar to many members of the Eos asteroid family whose spectral diversity has been interpreted as evidence for a partially differentiated parent asteroid (Mothe-Diniz et al. 2008). CV chondrite spectral and polarimetric data also resemble those of asteroid 21 Lutetia (e.g., Belskaya et al. 2010), recently encountered by the Rosetta spacecraft. Ground-based measurements of Lutetia indicate a high density of 2.4-5.1 g cm-3 (Drummond et al. 2010), while radar data seem to rule out a metallic surface composition (Shepard et al. 2008). If Rosetta spacecraft measurements confirm a high density and a CV-like surface composition for Lutetia, then we propose Lutetia may be an example of a partially differentiated carbonaceous chondrite parent body. Regardless, the very existence of primitive achondrites, which contain evidence of both relict chondrules and partial melting, are prima facie evidence for the formation of partially differentiated bodies.

Multiple parent bodies of ordinary chondrites

Thermal histories of chondrite parent bodies are calculated from an initial state with material in a powder-like form, taking into account the effect of consolidation state on thermal conductivity. The very low thermal conductivity of the starting materials makes it possible for a small body with a radius of less than 100 km to be heated by several hundred degrees even if long-lived radioactive elements in chondritic abundances are the only source of heat. The maximum temperature is determined primarily by the temperature at which sintering of the constituent materials occurs. The thermal state of the interior of a chondrite parent body after sintering has begun is nearly isothermal. Near the surface, however, where the material is unconsolidated and the thermal conductivity is much lower, the thermal gradient is quite large. This result contradicts the conventional 'onion-shell' model of chondrite parent bodies. But because the internal temperature is almost constant through the whole body, it supports a 'multiple-parent bodies' model, according to which each petrologic type of chondrite comes from a different parent body.

Vernazza, P.; Barge, P.; Zanda, B.

Although petrologic, chemical, and isotopic studies of ordinary chondrites and meteorites in general have largely helped establish a chronology of the earliest events of planetesimal formation and their evolution, there are several questions that cannot be resolved via laboratory measurements and/or experiments alone. Here, we propose the rationale for several new constraints on the formation and evolution of ordinary chondrite parent bodies (and, by extension, most planetesimals) from newly available spectral measurements and mineralogical analysis of main-belt S-type asteroids (83 objects) and unequilibrated ordinary chondrite meteorites (53 samples). Based on the latter, we suggest that spectral data may be usedmore » to distinguish whether an ordinary chondrite was formed near the surface or in the interior of its parent body. If these constraints are correct, the suggested implications include that: (1) large groups of compositionally similar asteroids are a natural outcome of planetesimal formation and, consequently, meteorites within a given class can originate from multiple parent bodies; (2) the surfaces of large (up to ∼200 km) S-type main-belt asteroids mostly expose the interiors of the primordial bodies, a likely consequence of impacts by small asteroids (D < 10 km) in the early solar system; (3) the duration of accretion of the H chondrite parent bodies was likely short (instantaneous or in less than ∼10{sup 5} yr, but certainly not as long as 1 Myr); (4) LL-like bodies formed closer to the Sun than H-like bodies, a possible consequence of the radial mixing and size sorting of chondrules in the protoplanetary disk prior to accretion.« less

Identifying factors that contribute to students' behavior and weight improvements during school-based obesity prevention interventions is critical for the development of effective programs. The current study aims to determine whether the support and resources that adolescent girls received from their families were associated with improvements in physical activity (PA), television use, dietary intake, body mass index (BMI) and body composition during participation in New Moves, a school-based intervention to prevent obesity and other weight-related problems. Adolescent girls in the intervention condition of New Moves (n = 135), and one parent of each girl, were included in the current analysis. At baseline, parents completed surveys assessing the family environment. At baseline and follow-up, 9–12 months later, girls' behaviors were self-reported, height and weight were measured by study staff and body fat was assessed using dual-energy X-ray absorptiometry. Results showed few associations between family environment factors and girls' likelihood of improving behavior, BMI or body composition. These findings suggest that in general, school-based interventions offer similar opportunities for adolescent girls to improve their PA, dietary intake, and weight, regardless of family support.

The physical as well as chemical properties of the meteorite parent bodies are reviewed and it is concluded that many differentiated meteorites were likely formed in asteroidal-sized parents. A new model is developed for the formation of pallasites at the interface between an iron core and olivine mantle in differentiated bodies only about 10 km in diameter, which are later incorporated into a second generation of larger (100 km) parent bodies.

Effect of the Parent-Adolescent Relationship on Adolescent Boys' Body Image and Subjective Well-Being.

Adolescent boys must cope with physical changes that hamper their ability to form a positive body image. Sociocultural messages influence the concepts of body image, personal appearance, and weight, encouraging men to develop lean and muscular bodies. The current study examined adolescent boys' body image and its relationship to their subjective well-being (SWB) and the effect of the parent-adolescent relationship on body image and SWB. Participating in the research were 107 adolescent boys in Israel, aged 13 to 18 years. Four questionnaires were utilized: demographic, body mass index, Body Investment Scale, and Personal Well-Being Index. The findings indicate a significant, medium positive correlation between SWB and body image. After controlling for the variable of parent-adolescent relationship, the correlation weakened, indicating that the parent-adolescent relationship has no effect on adolescent boys' SWB and body image. Body image was reported to be a predictor of SWB.

This project explores vaccine hesitancy through an artist-scientist collaboration. It aims to create better understanding of vaccine hesitant parents' health beliefs and how these influence their vaccine-critical decisions. The project interviews vaccine-hesitant parents in the Netherlands and Finland and develops experimental visual-narrative means to analyse the interview data. Vaccine-hesitant parents' health beliefs are, in this study, expressed through stories, and they are paralleled with so-called illness narratives. The study explores the following four main health beliefs originating from the parents' interviews: (1) perceived benefits of illness, (2) belief in the body's intelligence and self-healing capacity, (3) beliefs about the "inside-outside" flow of substances in the body, and (4) view of death as a natural part of life. These beliefs are interpreted through arts-based diagrammatic representations. These diagrams, merging multiple aspects of the parents' narratives, are subsequently used in a collaborative meaning-making dialogue between the artist and the scientist. The resulting dialogue contrasts the health beliefs behind vaccine hesitancy with scientific knowledge, as well as the authors' personal, and differing, attitudes toward these.

The purpose of this study was to review the published empirical correlates of television/video viewing among youth (2 to 18 years). A descriptive semi-quantitative review was conducted based on 68 primary studies. Variables consistently associated with TV/video viewing were ethnicity (non-white +), parent income (-), parent education (-), body weight (+), between meal snacking (+), number of parents in the house (-), parents TV viewing habits (+), weekend (+) and having a TV in the bedroom (+). Variables consistently unrelated to TV/video viewing were sex, other indicators of socio-economic status, body fatness, cholesterol levels, aerobic fitness, strength, other indicators of fitness, self-perceptions, emotional support, physical activity, other diet variables, and being an only child. Few modifiable correlates have been identified. Further research should aim to identify modifiable correlates of TV/video viewing if interventions are to be successfully tailored to reduce this aspect of inactivity among youth.

The asteroid-meteorite connection: Forging a new link to Vesta as the parent body of basaltic achondrite (HED) meteorites

Asteroid 4 Vesta has been at the center of the debate over the identity of the howardite eucrite diogenite (HED) parent body since the early 1970s. Despite its unique (among the 500 largest asteroids) compositional match to HED meteorites, substantial dynamical difficulties in delivering fragments from Vesta to the Earth have precluded any conclusive HED parent body link. These dynamical difficulties arise because Vesta's orbital location is far from known resonances. Consequently, it has been argued as dynamically improbable that meteoroid-sized (1 km) fragments could be excavated from Vesta with sufficient velocities to reach the resonances. Through new astronomical observations, numerous small (4-7 km) asteroids between Vesta and the 3:1 resonance have been discovered to have eucrite and diogenite compositions. Based on similar orbital elements to Vesta, all of these new asteroids are likely large impact fragments excavated from Vesta. Their current orbits imply ejection velocities in excess of 700 m/sec. Smaller (1 km) fragments can therefore be expected to have been ejected with velocities greater than 1 km/sec, sufficient to reach the 3:1 and v6 resonances. Thus it now appears to be dynamically viable for Vesta to be linked as the HED parent body.

This study aimed to identify socioeconomic correlates of computer/Internet use among parents of overweight preschool-aged children. A total of 470 baseline participants in a trial to prevent obesity in children 2 to 6.9 years old with body mass index ≥ 95th percentile or 85th to 95th percentile with one overweight parent were studied. Interviews with parents used Health Information National Trends Survey questions. Overall, 94% of the participants had home computers and 93% reported Internet usage. In adjusted models, parents with ≤ college degree (odds ratio = 4.8; 95% confidence interval = 1.2-18.3) or with household income ≤$50,000 (odds ratio = 7.6; 95% confidence interval = 2.2-26.8) had decreased likelihood of computer ownership. Of parents who reported going online, 63% used Internet to look for health/medical information for themselves and 42% for their children. Parents with ≤ a college degree or with body mass index <25 kg/m(2) were less likely to use Internet. Results support using the Internet for early childhood obesity prevention with enhanced outreach efforts for low socioeconomic status families.

Parental Perceptions of Body Mass Index Notification: A Qualitative Study.

There is a worldwide epidemic of obesity in children. To address obesity in children, emphasis must be on factors within family, school, and community environments. Although most parents and school officials are aware of the problem of overweight children, there are few data available to guide decision making about the acceptability of school-based body mass index (BMI) screening and referral programs. Parental insight is essential to determine the efficiency and effectiveness of BMI notification. The purpose of this qualitative study was to explore the perceptions of parents whose school-age children received a BMI referral letter stating their child is overweight. Purposeful convenience sampling was used to obtain 21 parents. Semistructured interviews were used to collect the data. Eight themes and corresponding subthemes emerged. The themes regarding parental perceptions were feelings about receiving the letter, causes of obesity, capabilities, barriers, role modeling, primary care provider response, school's role, and health screening process. The findings of this study can serve as the foundation and provide guidance for parents, schools, healthcare professionals, and communities when attempting to implement changes and programs to combat the epidemic of childhood obesity. © 2015, American School Health Association.

After participating in this activity, learners should be better able to: Evaluate the evidence regarding parental and child characteristics related to early-onset disordered eating. Eating disorders are rare in children, but disordered eating is common. Understanding the phenomenology of disordered eating in childhood can aid prevention of full-blown eating disorders. The purpose of this review is to systematically extract and synthesize the evidence on parental and child characteristics related to early-onset disordered eating. Systematic searches were conducted in PubMED/MEDLINE, EMBASE, and PsycInfo using the following search terms: eating disorder, disordered eating, problem eating, anorexia nervosa, bulimia nervosa, binge eating, child, preadolescent, and early onset. Studies published from 1990 to 2013 addressing parental and child characteristics of disordered eating in children aged 6 to 12 years were eligible for inclusion. The search was restricted to studies with cross-sectional, case-control, or longitudinal designs, studies in English, and with abstracts available. Forty-four studies fit these criteria. Most studies were based on community samples with a cross-sectional design. The included studies varied considerably in size, instruments used to assess early-onset disordered eating, and parental and child characteristics investigated. Important determinants included the following: higher body weight, previously reported disordered eating, body dissatisfaction, depression, parental disordered eating, and parental comments/concerns about child's weight and eating. The findings were inconsistent for sex, age, socioeconomic status, ethnicity, self-esteem/worth, and parental body weight. In conclusion, characteristics related to early-onset disordered eating have mainly been explored with a cross-sectional design. Full understanding of causal pathways will require good-quality longitudinal studies designed to address the influence of parental eating behaviors, mental and physical health, family interactions, and child growth patterns.

Body image and eating patterns develop in early childhood and are influenced by the family environment. This research evaluated Confident Body, Confident Child (CBCC), an intervention for parents of 2- to 6-year-old children, designed to promote body satisfaction, healthy eating, and weight management in early childhood. A randomized controlled trial compared four groups: (A) received the CBCC resource pack and a workshop, (B) received the CBCC resource pack only, (C) received a nutrition-only resource and (D) received no interventions until all questionnaires were completed (i.e., functioned as waitlist control). Measures of parenting variables relevant to child body image and eating patterns, parent-report of child weight, and evaluation questions about the resource, were implemented pre- and post-intervention. At 6-weeks post-intervention, the CBCC resource was associated with significant reductions in parents' intentions to use behaviors that increase the risk of negative body attitudes or unhealthy eating in their children, in parents' use of feeding practices associated with childhood overweight, and in television watching during family meals. Significant increases in parents' intentions to use positive behaviors and knowledge of child body image and healthy eating patterns were also found. Superior results were found for the CBCC resource + workshop condition, suggesting it is the preferred delivery method. CBCC positively impacts parenting variables associated with childhood risk for body dissatisfaction, unhealthy eating and weight. © 2016 Wiley Periodicals, Inc.

The Diversity of Anomalous HEDs: Isotopic Constraints on the Connection of EET 92023, GRA 98098, and Dhofar 700 With Vesta

The possibility for multiple parent bodies, instead of a common parent body of Vesta, for eucrites has been suggested based on the variable oxygen isotopic composition observed in some eucrites.. Recently, we added an extra dimension to the discussion based on the (epsilon)54Cr composition of the same eucrites with known (delta)17O to compare with the normal eucrites. The combined (delta)17O and (epsilon)54Cr isotope systematics for Pasamonte, PCA 91007, A-881394, and Ibitira indicate their likely origin from multiple different parent bodies than the normal eucrites. Often the qualifier anomalous is used to identify HEDs with (delta)17O values that deviate significantly (>3(sigma)) from the mean HED (delta)17O. However, variations in eucrites and diogenites also include unique geochemical characteristics such as bulk composition, trace element abundances, or volatile concentrations, in addition to (delta)17O. Here, we investigate three such geochemically anomalous HEDs: Elephant Moraine (EET) 92023, Graves Nunataks (GRA) 98098, and Dhofar 700. In addition, to verify the homogeneity of (epsilon)54Cr observed for normal HEDs thus far, a set of seven eucrites and diogenites considered normal samples were also investigated.

Rocket bodies comprise a class of human-made space debris that are at the same time essential for launching every spacecraft from the Earth, but are also a significant source of debris both as intact objects, as well as fragmented debris. Unspent fuel has been long theorized as a potential cause of catastrophic rocket body break-ups. Given typical orbital speeds range from approximately 2-3 kilometers per second at Geosynchronous Orbit (GEO) and up to 15 kilometers per second in low Earth orbit (LEO), collisions with uncatalogued and undetected debris can also cause catastrophic breakups. Understanding break-ups is a necessary step in preventing them, and one key step in that process is to correlate and characterize daughter fragments with their parent bodies. Two very different methods include (1) conducting photometric surveys to correlate an object's motion and orbital elements to the parent body, and (2) characterizing what materials comprise the target to determine whether those materials are consistent with the parent body or like objects. With this in mind, photometric data were taken shortly after the breakup of one rocket body for short-term orbital studies, and a suite of spectral data were taken of rocket bodies that are fully intact to compare with debris, for characterization studies. Targets included Titan Transtage, Briz-M, and Ariane rocket bodies and debris. Spectra of each sub-class of rocket body were very similar within their rocket body type, but differed distinctly from one type to the next, supporting the effectiveness of this approach.

A Model of Female Sexual Desire: Internalized Working Models of Parent-Child Relationships and Sexual Body Self-Representations.

2017-11-01

The etiology of low female sexual desire, the most prevalent sexual complaint in women, is multi-determined, implicating biological and psychological factors, including women's early parent-child relationships and bodily self-representations. The current study evaluated a model that hypothesized that sexual body self-representations (sexual subjectivity, self-objectification, genital self-image) explain (i.e., mediate) the relation between internalized working models of parent-child relationships (attachment, separation-individuation, parental identification) and sexual desire in heterosexual women. We recruited 614 young, heterosexual women (M = 25.5 years, SD = 4.63) through social media. The women completed an online survey. Structural equation modeling was used. The hypotheses were supported in that the relation between internalized working models of parent-child relationships (attachment and separation-individuation) and sexual desire was mediated by sexual body self-representations (sexual body esteem, self-objectification, genital self-image). However, parental identification was not related significantly to sexual body self-representations or sexual desire in the model. Current findings demonstrated that understanding female sexual desire necessitates considering women's internalized working models of early parent-child relationships and their experiences of their bodies in a sexual context. Treatment of low or absent desire in women would benefit from modalities that emphasize early parent-child relationships as well as interventions that foster mind-body integration.

To analyze the correlation between children and adolescents' body shape parameters and parent's dissatisfaction on it. Stratified cluster sampling method was used to select students and their parents, and height, weight, waist circumference (WC), hip circumference (HC), skinfold thichness of the students were measured. Body image from parents was studied through the 'Ma body figural shape'. Correlation between body shape parameters and dissatisfaction towards them from the parents was analyzed under both simple- and multiple-level methods. The overall prevalence of dissatisfaction on body-shapes from parents was 69.0%, including 28.6% of the parents expecting children to be fat (PEBF) while, 40.4% of the parents expecting their children to be thin (PEBT). In males, parameters as height, weight, WC, HC, skin fold thickness, BMI in PEBT were 1.9 cm, 11.9 kg, 13.2 cm, 8.8 cm, 32.3 mm, 4.7 kg/m² respectively, all higher than the satisfaction from the parents (PBIS) (all P < 0.05), and these parameters were 2.3 cm, 7.1 kg, 7.2 cm, 5.8 cm, 14.1 mm, 2.3 kg/m² higher in PBIS than that of PEBF, respectively (all P < 0.05). In females, parameters as weight, WC, HC, skinfold thickness, BMI in PEBT appeared to be 8.6 kg, 9.1 cm, 6.6 cm, 21.9 mm, 3.5 kg/m² higher than that of PBIS (all P < 0.01), and were 5.5 kg, 5.9 cm, 5.4 cm, 10.4 mm, 1.8 kg/m² higher in PBIS than that of PEBF, respectively, plus the difference of height was 3.6 cm more (P < 0.01). Differences of body shape on parameters between PEBT and PBIS were larger in primary school students than in middle school students. However, the differences of body shape parameters between PBIS and PEBF appeared higher in middle school students than in primary school male students, but were higher in female students in primary than in middle school students. The prevalence of body dissatisfaction related to children and adolscents' body shape parameters from parents was high. Parents in the PEBT group seemed to have paid more attention to children's body shape parameters at low age. However, parents in PEBF group might have paid more attention to children's body shape parameters at high age in males or at low age in females.

This study examines the effectiveness of a wellness-based prevention program on elementary and junior high students' body image, personal attitudes, and eating behaviors. Group differences in measures of student attitudes and eating behaviors are examined to determine the effect of targeting different participant combinations (students, parents, and teachers) in 10 groups. For elementary schools, student participants consisted of control (no intervention) (n = 36), student only (n = 81), student/parent (n = 124), student/parent/teacher (n = 103), and parent/teacher (n = 149). For junior high schools, student participants consisted of control (n = 143), student only (n=215), student/parent (n=65), student/parent/teacher (n = 14), and parent/teacher (n = 177). Overall, complete data was available for 1,095 students, 114 parents and 92 teachers. Results indicate that self-concept and eating attitudes and behaviors were positively affected by participation in the program. For example, in elementary schools posttest scores on the behavior subscale of the self-concept measure are significantly higher for the student/parent/teacher group than for the control group. Results indicate that a one-time wellness-based eating disorder prevention program with students, which have in the past shown to be minimally effective, may be more effective in changing attitudes and behaviors when teachers and parents are involved.

Objectively measured physical activity is low in British children, and declines as childhood progresses. Observational studies suggest that dog-walking might be a useful approach to physical activity promotion in children and adults, but there are no published public health interventions based on dog-walking with children. The Children, Parents, and Pets Exercising Together Study aims to develop and evaluate a theory driven, generalisable, family-based, dog walking intervention for 9-11 year olds. The Children, Parents, and Pets Exercising Together Study is an exploratory, assessor-blinded, randomised controlled trial as defined in the UK MRC Framework on the development and evaluation of complex interventions in public health. The trial will follow CONSORT guidance. Approximately 40 dog-owning families will be allocated randomly in a ratio of 1.5:1 to receive a simple behavioural intervention lasting for 10 weeks or to a 'waiting list' control group. The primary outcome is change in objectively measured child physical activity using Actigraph accelerometry. Secondary outcomes in the child, included in part to shape a future more definitive randomised controlled trial, are: total time spent sedentary and patterning of sedentary behaviour (Actigraph accelerometry); body composition and bone health from dual energy x-ray absorptiometry; body weight, height and BMI; and finally, health-related quality of life using the PedsQL. Secondary outcomes in parents and dogs are: changes in body weight; changes in Actigraph accelerometry measured physical activity and sedentary behaviour. Process evaluation will consist of assessment of simultaneous child, parent, and dog accelerometry data and brief interviews with participating families. The Children, Parents, and Pets Exercising Together trial should be the first randomised controlled study to establish and evaluate an intervention aimed at dog-based physical activity promotion in families. It should advance our understanding of whether and how to use pet dogs to promote physical activity and/or to reduce sedentary behaviour in children and adults. The trial is intended to lead to a subsequent more definitive randomised controlled trial, and the work should inform future dog-based public health interventions such as secondary prevention interventions in children or adults.

Genealogy of Iron and Pallasite Meteorites as Revealed by Cr Isotopes

Sanborn, M.; Yin, Q. Z.; Ziegler, K. G.

2017-12-01

The parent bodies and/or chemical reservoirs from which iron and stony-iron meteorites originated are not very well understood. It is unclear if particular groups of iron or stony-iron meteorites originated from melting of already known chondritic parent bodies or are representating new chemical reservoirs. Potential connections between iron meteorites and pallasites and known parent bodies have been suggested based on oxygen isotopes. Proposed genetic relationships include the IVA irons with ordinary chondrites1 and the anomalous pallasite Eagle Station with the CV chondrites2. Here, we use the power of Cr isotopes to further resolve potential connections between IVA irons and pallasites and specific parent bodies. Our new measurements of Cr isotopic composition of silicate inclusions from two IVA irons, Steinbach and São João Nepomuceno, are shown to be indistinguishable from that of the ordinary chondrites. Coupling Cr with oxygen indicates the IVA irons likely originated from the same source as LL chondrites. In contrast with Eagle Station, the new Cr isotope measurements combined with oxygen indicates the MGP Brenham and Krasnojarsk sampled a source material similar to that of the anomalous HEDs. As with Eagle Station, the Milton pallasite exhibits a carbonaceous chondrite (CC) Cr isotope composition, indicating that Eagle Station was not the lone case of a pallasite originating from a CC reservoir. By establishing these genetic relationships using Cr isotopes, it is now evident that the differentiation activity sampled by IVA irons and pallasites represents processes occurring on a diverse set of parent bodies in the early Solar System.

2015-01-01

Objective The current study compared child weight status, social skills, body dissatisfaction, and health-related quality of life (HRQOL), as well as parent distress and family functioning in youth who are overweight and obese (OV/OB) with versus without clinical anxiety symptoms. Method Participants included 199 children 7–12 years old (Mage= 9.88 years) who were OV/OB and their parents. Children completed social skills, body dissatisfaction, and HRQOL questionnaires. Parents completed the Child Behavior Checklist (CBCL) and child HRQOL, parent distress, family functioning, and demographic questionnaires. Children were placed in two groups based on CBCL Anxiety Problems scale scores; the OV/OB + Clinical Anxiety group included children with T-scores ≥ 65 (n = 23) and children with T-scores ≤ 59 comprised the OV/OB group (n = 176). Results After controlling for covariates, children in the OV/OB + Clinical Anxiety group reported more body dissatisfaction (F [1,198] = 5.26, p =.023, partial η2 = .027) and lower total HRQOL (F [1,198] = 8.12, p = .005, η2=.041) and had parents who reported higher psychological distress (F [1,198] = 5.48, p = .020, η2=.028) and lower child total HRQOL (F [1,198] = 28.23, p < .001, η2=.128) compared to children in the OV/OB group. Group differences were not significant for child weight status, social skills, or family functioning. Conclusion Clinically significant anxiety among children who are OV/OB is associated with increased body dissatisfaction and parent psychological distress, as well as decreased HRQOL. Findings have implications for the assessment and treatment of anxiety symptoms in pediatric obesity. PMID:26468940

Summary The course of cystic fibrosis (CF) progression in children is affected by parent adherence to treatment plans. The Theory of Reasoned Action (TRA) posits that intentions are the best behavioral predictors and that intentions reasonably follow from beliefs (“determinants”). Determinants are affected by multiple “background factors,” including spirituality. This study’s purpose was to understand whether two parental adherence determinants (attitude towards treatment and self-efficacy) were associated with spirituality (religious coping and sanctification of the body). We hypothesized that parents’ attitudes toward treatment adherence are associated with these spiritual constructs. A convenience sample of parents of children with CF aged 3–12 years (n = 28) participated by completing surveys of adherence and spirituality during a regular outpatient clinic visit. Type and degree of religious coping was examined using principal component analysis. Adherence measures were compared based on religious coping styles and sanctification of the body using unpaired t-tests. Collaborative religious coping was associated with higher self-efficacy for completing airway clearance (M = 1070.8; SD = 35.8; P = 0.012), for completing aerosolized medication administration (M = 1077.1; SD = 37.4; P = 0.018), and for attitude towards treatment utility (M = 38.8; SD = 2.36; P = 0.038). Parents who attributed sacred qualities to their child’s body (e.g., “blessed” or “miraculous”) had higher mean scores for self-efficacy (airway clearance, M = 1058.6; SD = 37.7; P = 0.023; aerosols M = 1070.8; SD = 41.6; P = 0.020). Parents for whom God was manifested in their child’s body (e.g., “My child’s body is created in God’s image”) had higher mean scores for self-efficacy for airway clearance (M = 1056.4; SD = 59.0; P = 0.039), aerosolized medications (M = 1068.8; SD = 42.6; P = 0.033) and treatment utility (M = 38.8; SD = 2.4; P = 0.025). Spiritual constructs show promising significance and are currently undervalued in chronic disease management. PMID:22170872

Parenting styles such as authoritarian, disengaged, or permissive are thought to be associated with greater adolescent obesity risk than an authoritative style. This study assessed the relationship between parenting styles and changes in body mass index (BMI) from adolescence to young adulthood. The study included self-reported data from adolescents in the National Longitudinal Study of Adolescent Health. Factor mixture modeling, a data-driven approach, was used to classify participants into parenting style groups based on measures of acceptance and control. Latent growth modeling (LGM) identified patterns of developmental changes in BMI. After a number of potential confounders were controlled for, parenting style variables were entered as predictors of BMI trajectories. Analyses were also conducted for male and female individuals of 3 racial-ethnic groups (Hispanic, black, white) to assess whether parenting styles were differentially associated with BMI trajectories in these 6 groups. Parenting styles were classified into 4 groups: authoritarian, disengaged, permissive, and balanced. Compared with the balanced parenting style, authoritarian and disengaged parenting styles were associated with a less steep average BMI increase (linear slope) over time, but also less leveling off (quadratic) of BMI over time. Differences in BMI trajectories were observed for various genders and races, but the differences did not reach statistical significance. Adolescents who reported having parents with authoritarian or disengaged parenting styles had greater increases in BMI as they transitioned to young adulthood despite having a lower BMI trajectory through adolescence.

Objective Parenting styles such as authoritarian, disengaged, or permissive are thought to be associated with greater adolescent obesity risk than an authoritative style. This study assessed the relationship between parenting styles and changes in body mass index (BMI) from adolescence to young adulthood. Methods The study included self-reported data from adolescents in the National Longitudinal Study of Adolescent Health. Factor mixture modeling, a data-driven approach, was used to classify participants into parenting style groups based on measures of acceptance and control. Latent growth modeling (LGM) identified patterns of developmental changes in BMI. After a number of potential cofounders were controlled for, parenting style variables were entered as predictors of BMI trajectories. Analyses were also conducted for males and females of three racial/ethnic groups (Hispanic, black, white) to assess whether parenting styles were differentially associated with BMI trajectories in these 6 groups. Results Parenting styles were classified into 4 groups: authoritarian, disengaged, permissive, and balanced. Compared with the balanced parenting style, authoritarian and disengaged parenting styles were associated with a less steep average BMI increase (linear slope) over time, but also less leveling off (quadratic) of BMI over time. Differences in BMI trajectories were observed for various genders and races, but the differences did not reach statistical significance. Conclusions Adolescents who reported having parents with authoritarian or disengaged parenting styles had greater increases in BMI as they transitioned to young adulthood despite having a lower BMI trajectory through adolescence.

Attrition in pediatric weight management is a substantial problem. This study examined factors associated with short- and long-term attrition from a lifestyle and behavioral intervention for parents of children with overweight or obesity. Fifty-two families with children ages 6 to 12 years old and body mass index at or above the 85th percentile participated in a randomized controlled trial focused on parents, comparing parent-based cognitive behavioral therapy with parent-based psychoeducation for pediatric weight management. We examined program attrition using two clinical phases of the intervention: short-term and long-term attrition, modeled using the general linear model. Predictors included intervention type, child/parent weight status, sociodemographic factors, and health of the family system. Higher self-assessed health of the family system was associated with lower short-term attrition; higher percentage of intervention sessions attended by parents was associated with lower long-term attrition. Different variables were significant in our short- and long-term models. Attrition might best be conceptualized based on short- and long-term phases of clinical, parent-based interventions for pediatric weight management.

This study investigated whether perceptions of parenting behaviours predict young adolescents' nutritional intake and body fatness. The randomly selected study sample consisted of 106 13-15 years olds from Houston Metropolitan Statistical Area. Parenting style variables were created by cluster analysis and factor analysis. A two-cluster solution for both maternal and paternal parenting style represented authoritative vs. non-authoritative parenting. Two parenting dimension factors derived were maternal/paternal nurturing and control. For adolescents' energy and nutrient intake, greater maternal nurturing appeared to be most beneficial given its association with lower consumption of total kilocalorie and lower saturated fat intake. Paternal nurturing was associated with lower sodium intake, whereas paternal control predicted lower percentage of kilocalories from carbohydrate and percentage Dietary Reference Intake for dietary fibre, and greater percentage of kilocalories from total fat. Maternal authoritative parenting and lower maternal control over their adolescents may have protective effects against having heavier and fatter adolescents given their associations with adolescents' body weight, sub-scapular skinfold, waist circumference, body mass index, and the tendencies of being at risk of overweight and being overweight. None of paternal parenting styles or dimensions appeared to be significantly related to adolescents' body fatness.

The Healthy Homes/Healthy Kids Preschool (HHHK-Preschool) pilot program is an obesity prevention intervention integrating pediatric care provider counseling and a phone-based program to prevent unhealthy weight gain among 2- to 4-year-old children at risk for obesity (BMI percentile between the 50th and 85th percentile and at least one overweight parent) or currently overweight (85th percentile ≤ BMI < 95th percentile). The aim of this randomized, controlled pilot study was to evaluate the feasibility, acceptability, and potential efficacy of the HHHK-Preschool intervention. Sixty parent-child dyads recruited from pediatric primary care clinics were randomized to: (1) the Busy Bodies/Better Bites Obesity Prevention Arm or the (2) Healthy Tots/Safe Spots safety/injury prevention Contact Control Arm. Baseline and 6-month data were collected, including measured height and weight, accelerometry, previous day dietary recalls, and parent surveys. Intervention process data (e.g., call completion) were also collected. High intervention completion and satisfaction rates were observed. Although a statistically significant time by treatment interaction was not observed for BMI percentile or BMI z-score, post-hoc examination of baseline weight status as a moderator of treatment outcome showed that the Busy Bodies/Better Bites obesity prevention intervention appeared to be effective among children who were in the overweight category at baseline relative to those who were categorized as at risk for obesity (p = 0.04). HHHK-Preschool pilot study results support the feasibility, acceptability, and potential efficacy in already overweight children of a pediatric primary care-based obesity prevention intervention integrating brief provider counseling and parent-targeted phone coaching. What's New: Implementing pediatric primary care-based obesity interventions is challenging. Previous interventions have primarily involved in-person sessions, a barrier to sustained parent involvement. HHHK-preschool pilot study results suggest that integrating brief provider counseling and parent-targeted phone coaching is a promising approach.

Simulations of Collisional Disruption at the Catastrophic Impact Energy Threshold: Effect of the Target's Internal Structure and Diameter

Recent simulations of asteroid break-ups, including both the fragmentation of the parent body and the gravitational interactions of the fragments, have allowed to reproduced successfully the main properties of asteroid families formed in different regimes of impact energy. Here, using the same kind of simulations, we concentrate on a single regime of impact energy, the so-called catastrophic threshold usually designated by Qcrit, which results in the escape of half of the target's mass. Considering a wide range of diameter values and two kinds of internal structures of the parent body, monolithic and pre-shattered, we analyse their potential influences on the value of Qcrit and on the collisional outcome limited here to the fragment size and ejection speed distributions, which are the main outcome properties used by collisional models to study the evolutions of the different populations of small bodies. For all the considered diameters and the two internal structures of the parent body, we confirm that the process of gravitational reaccumulation is at the origin of the largest remnant's mass. We then find that, for a given diameter of the parent body, the impact energy corresponding to the catastrophic disruption threshold is highly dependent on the internal structure of the parent body. In particular, a pre-shattered parent body containing only damaged zones but no macroscopic voids is easier to disrupt than a monolithic parent body. Other kinds of internal properties that can also characterize small bodies in real populations will be investigated in a future work.

To examine whether changes in parent motivation over the course of a pediatric obesity intervention are significantly associated with long-term changes in treatment outcomes.   Study hypotheses were tested with a secondary data analysis of a randomized controlled trial (N = 42). Study analyses tested whether baseline to posttreatment change in total score for a self-report parent motivation measure (Parent Motivation Inventory [PMI]) was significantly associated with baseline to 6-month follow-up changes in body mass index z-score (zBMI), dietary variables, and physical activity.   Increases in PMI were significantly associated with decreased zBMI, decreased consumption of sugar-sweetened beverages and sweets, and increased consumption of artificially sweetened beverages.   Given that increases in parent motivation were associated with some treatment benefits, future research should evaluate the impact of directly assessing and targeting parent motivation on weight outcomes for preschoolers participating in a weight management program. © The Author 2014.

Approximately 25% of US 2-to-5-year olds are overweight and ethnic minority groups are disproportionately affected. We explored the relationship between parent demographic characteristics, various perinatal/early childhood (EC) factors, and child body mass index (BMI) to determine possible contributors to these disparities. A preschool-based randomized controlled (N = 28 centers) obesity prevention intervention was conducted among multiethnic 2-to-5 year olds. Baseline assessment of demographic characteristics, various perinatal/EC factors, and child BMI were analyzed via generalized linear mixed models and logistic regression analysis. Foreign-born parents were almost 2.5 times as likely to have an obese child versus children of US-born parents (OR 2.43, 95% CI 1.53-3.87). Families who spoke Spanish only or a combination of Creole/English at home were over twice as likely to have an obese preschool child versus families who spoke English only at home. Parent place of birth and language spoken at home plays a significant role in early childhood obesity. Future early childhood healthy weight initiatives should incorporate strategies that take into account these particular parent characteristics.

While overweight and obese children are more likely to have overweight or obese parents, less is known about the effect of parental weight status on children's success in weight management programmes. This study was a secondary data analysis of a randomized controlled trial and investigated the impact of having zero, one or two obese parents on children's success in a school-based weight management programme. Sixty-one Mexican-American children participated in a 24-week school-based weight management intervention which took place in 2005-2006. Children's heights and weights were measured at baseline, 3, 6 and 12 months. Parental weight status was assessed at baseline. Repeated measures anova and ancova were conducted to compare changes in children's weight within and between groups, respectively. Within-group comparisons revealed that the intervention led to significant decreases in standardized body mass index (zBMI) for children with zero (F = 23.16, P < .001) or one obese (F = 4.99, P < .05) parent. Between-group comparisons indicated that children with zero and one obese parents demonstrated greater decreases in zBMI compared to children with two obese parents at every time point. The school-based weight management programme appears to be most efficacious for children with one or no obese parents compared to children with two obese parents. These results demonstrate the need to consider parental weight status when engaging in childhood weight management efforts. © 2015 World Obesity.

Selection on parental performance opposes selection for larger body mass in a wild population of blue tits.

There is abundant evidence in many taxa for positive directional selection on body size, and yet little evidence for microevolutionary change. In many species, variation in body size is partly determined by the actions of parents, so a proposed explanation for stasis is the presence of a negative genetic correlation between direct and parental effects. Consequently, selecting genes for increased body size would result in a correlated decline in parental effects, reducing body size in the following generation. We show that these arguments implicitly assume that parental care is cost free, and that including a cost alters the predicted genetic architectures needed to explain stasis. Using a large cross-fostered population of blue tits, we estimate direct selection on parental effects for body mass, and show it is negative. Negative selection is consistent with a cost to parental care, mainly acting through a reduction in current fecundity rather than survival. Under these conditions, evolutionary stasis is possible for moderately negative genetic correlations between direct and parental effects. This is in contrast to the implausibly extreme correlations needed when care is assumed to be cost-free. Thus, we highlight the importance of accounting correctly for complete selection acting on traits across generations. © 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution.

The course of cystic fibrosis (CF) progression in children is affected by parent adherence to treatment plans. The Theory of Reasoned Action (TRA) posits that intentions are the best behavioral predictors and that intentions reasonably follow from beliefs ("determinants"). Determinants are affected by multiple "background factors," including spirituality. This study's purpose was to understand whether two parental adherence determinants (attitude towards treatment and self-efficacy) were associated with spirituality (religious coping and sanctification of the body). We hypothesized that parents' attitudes toward treatment adherence are associated with these spiritual constructs. A convenience sample of parents of children with CF aged 3-12 years (n = 28) participated by completing surveys of adherence and spirituality during a regular outpatient clinic visit. Type and degree of religious coping was examined using principal component analysis. Adherence measures were compared based on religious coping styles and sanctification of the body using unpaired t-tests. Collaborative religious coping was associated with higher self-efficacy for completing airway clearance (M = 1070.8; SD = 35.8; P = 0.012), for completing aerosolized medication administration (M = 1077.1; SD = 37.4; P = 0.018), and for attitude towards treatment utility (M = 38.8; SD = 2.36; P = 0.038). Parents who attributed sacred qualities to their child's body (e.g., "blessed" or "miraculous") had higher mean scores for self-efficacy (airway clearance, M = 1058.6; SD = 37.7; P = 0.023; aerosols M = 1070.8; SD = 41.6; P = 0.020). Parents for whom God was manifested in their child's body (e.g., "My child's body is created in God's image") had higher mean scores for self-efficacy for airway clearance (M = 1056.4; SD = 59.0; P = 0.039), aerosolized medications (M = 1068.8; SD = 42.6; P = 0.033) and treatment utility (M = 38.8; SD = 2.4; P = 0.025). Spiritual constructs show promising significance and are currently undervalued in chronic disease management. Copyright © 2011 Wiley Periodicals, Inc.

In 2003, Arkansas became the first state to require body mass index (BMI) testing in public schools to raise awareness of the growing obesity epidemic among children and adolescents. Limited information exists regarding the effectiveness of school-based BMI screening programs. The purpose of this study was to determine if BMI health report cards affected parents' knowledge or actions regarding their child's health and to determine the accuracy of parents' perceptions of their child as underweight, normal weight, or overweight according to their child's BMI. A questionnaire was developed with the help of physical educators, pediatricians, and exercise scientists to determine parents' perceptions and behaviors regarding BMI report cards. The questionnaire was distributed to parents/guardians of children who sought medical care at two pediatrician's offices in Arkansas. Based on responses to survey questions, parents are not making changes to their child's diet and exercise habits if their child is classified as "at risk" or "overweight." However, parents did report that BMI health report cards are influencing their knowledge about their child's health. The majority of parents in the study (approximately 66%) did not accurately perceive their child's BMI category.

The fall of the Annama meteorite occurred early morning (local time) on April 19, 2014 on the Kola Peninsula (Russia). Based on mineralogy and physical properties, Annama is a typical H chondrite. It has a high Ar-Ar age of 4.4 Ga. Its cosmic ray exposure history is atypical as it is not part of the large group of H chondrites with a prominent 7-8 Ma peak in the exposure age histograms. Instead, its exposure age is within uncertainty of a smaller peak at 30 ± 4 Ma. The results from short-lived radionuclides are compatible with an atmospheric pre-entry radius of 30-40 cm. However, based on noble gas and cosmogenic radionuclide data, Annama must have been part of a larger body (radius >65 cm) for a large part of its cosmic ray exposure history. The 10Be concentration indicates a recent (3-5 Ma) breakup which may be responsible for the Annama parent body size reduction to 30-35 cm pre-entry radius.

Reversing the obesity epidemic requires the development and evaluation of childhood obesity intervention programs. Lifestyle Triple P is a parent-focused group program that addresses three topics: nutrition, physical activity, and positive parenting. Australian research has established the efficacy of Lifestyle Triple P, which aims to prevent excessive weight gain in overweight and obese children. The aim of the current randomized controlled trial is to assess the effectiveness of the Lifestyle Triple P intervention when applied to Dutch parents of overweight and obese children aged 4-8 years. This effectiveness study is called GO4fit. Parents of overweight and obese children are being randomized to either the intervention or the control group. Those assigned to the intervention condition receive the 14-week Lifestyle Triple P intervention, in which they learn a range of nutritional, physical activity and positive parenting strategies. Parents in the control group receive two brochures, web-based tailored advice, and suggestions for exercises to increase active playing at home. Measurements are taken at baseline, directly after the intervention, and at one year follow-up. Primary outcome measure is the children's body composition, operationalized as BMI z-score, waist circumference, and fat mass (biceps and triceps skinfolds). Secondary outcome measures are children's dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, parental self-efficacy, and body composition of family members (parents and siblings). Our intervention is characterized by a focus on changing general parenting styles, in addition to focusing on changing specific parenting practices, as obesity interventions typically do. Strengths of the current study are the randomized design, the long-term follow-up, and the broad range of both self-reported and objectively measured outcomes.

Objective To determine whether parents who prefer a heavier child would underestimate their child's weight more than those who prefer a leaner child. Methods Participants were Mexican American families (312 mothers, 173 fathers, and 312 children ages 8-10) who were interviewed and had height and weight measurements. Parents reported their preferred child body size and their perceptions of their child's weight. Parents’ underestimation of their child's weight was calculated as the standardized difference between parent's perception of their child's weight and the child's body mass index (BMI) z-score. Demographic factors and parental BMI were also assessed. Results Although 50% of children were overweight or obese, only 11% of mothers and 10% of fathers perceived their children as being somewhat or very overweight. Multiple regressions controlling for covariates (parental BMI and child age) showed that parents who preferred a heavier child body size underestimated their children's weight more, compared to those who preferred a leaner child (β for mothers = .13, p < .03; (β for fathers = .17, p < .03). Conclusions for Practice Parents who preferred a heavier child body size underestimated their child's weight to a greater degree than parents who preferred a leaner child. Attempts by pediatricians to correct parents’ misperceptions about child weight may damage rapport and ultimately fail if the misperception is actually a reflection of parents’ preferences, which may not be readily amenable to change. Future research should address optimal methods of communication about child overweight which take into account parent preferences. PMID:27016351

This study investigated the relations among physical, emotional, and sexual abuse up to adolescence and subsequent perception of body size, detection of changes in body size, and body-esteem. The role of parenting history in abused participants was also examined. 38 college undergraduate women, half of whom had been abused, reported instances of abuse, childhood parenting history, and current body-esteem. A recently developed software program of Gardner and Boice was used to present a series of distorted frontal profiles of each participant's own body for the women to rate as being too wide or too thin. A psychophysical procedure called adaptive probit estimation was used to measure the amount of over- and underestimation of these ratings and whether these changes were statistically significant. Analysis showed abused participants had distorted perceptions of body size, although the direction of the distortion was not consistent. There was no difference in detection of changes in body size. Abused and nonabused participants differed on measures of body-esteem and on ratings of most parenting experiences, including experiences with both mothers and fathers.

An initial perspective of S-asteroid subtypes within asteroid families

1993-01-01

Many main belt asteroids cluster around certain values of semi-major axis (a), inclination (i), and eccentricity (e). Hirayama was the first to notice these concentrations which he interpreted as evidence of disruptions of larger parent bodies. He called these clusters 'asteroid families'. The term 'families' is increasingly reserved for genetic associations to distinguish them from clusters of unknown or purely dynamical origin (e.g. the Phocaea cluster). Members of a genetic asteroid family represent fragments derived from various depths within the original parent planetesimal. Thus, family members offer the potential for direct examination of the interiors of parent bodies which have undergone metamorphism and differentiation similar to that occurring in the inaccessible interiors of terrestrial planets. The differentiation similar to that occurring in the inaccessible interiors of terrestrial planets. The condition that genetic family members represent the fragments of a parent object provides a critical test of whether an association (cluster in proper element space) is a genetic family. Compositions (types and relative abundances of materials) of family members must permit the reconstruction of a compositionally plausible parent body. The compositions of proposed family members can be utilized to test the genetic reality of the family and to determine the type and degree of internal differentiation within the parent planetesimal. The interpretation of the S-class mineralogy provides a preliminary evaluation of family memberships. Detailed mineralogical and petrological analysis was done based on the reflectance spectra of 39 S-type asteroids. The result is a division of the S-asteroid class into seven subtypes based on compositional differences. These subtypes, designated S(I) to S(VII), correspond to surface silicate assemblages ranging from monomineralic olivine (dunites) through olivine-pyroxene mixtures to pure pyroxene or pyroxene-feldspar mixtures (basalts). The most general conclusion is that the S-asteroids cannot be treated as a single group of objects without greatly oversimplifying their properties. Each S-subtype needs to be treated as an independent group with a distinct evolutionary history.

Background: Although parental obesity is a well-established predisposing factor for the development of obesity, associations between regional body compositions, resting metabolic rates (RMR), and physical activity (PA) of parents and their pre-school children remain unknown. The objective of this study was to investigate parent-child correlations for total and regional body compositions, resting energy expenditures, and physical activity. Methods: Participants were 89 children aged 2-6 years and their parents, consisting of 61 families. Resting metabolic rate was assessed using indirect calorimetry. Total and regional body compositions were measured by both dual energy X-ray absorptiometry (DXA) and deuterium dilution. Physical activity was assessed by an accelerometer. Results: There was a significant parent-offspring regression for total fat free mass (FFM) between children and their mothers (P=0.02), fathers (P=0.02), and mid-parent (average of father and mother value) (P=0.002) when measured by DXA. The same was true for fat mass (FM) between children and mothers (P<0.01), fathers (P=0.02), and mid-parent (P=0.001). There was no significant association between children and parents for physical activity during the entire week, weekend, weekdays, and different parts of days, except for morning activity, which was positively related to the mothers’ morning activities (P<0.01) and mid-parent (P=0.009). No association was found between RMR of children and parents before and after correction for FFM and FM. Conclusion: These data suggest a familial resemblance for total body composition between children and their parents. Our data showed no familial resemblance for PA and RMR between children and their parents. PMID:26989715

The main objectives of the current study was i) to prospectively examine if chronic musculoskeletal pain in parents is associated with risk of chronic musculoskeletal pain in their adult offspring, and ii) to assess if these parent-offspring associations are modified by offspring body mass index and leisure time physical activity. We used data on 4,742 adult offspring linked with their parents who participated in the population-based HUNT Study in Norway in 1995-97 and in 2006-08. Family relations were established through the national Family Registry. A Poisson regression model was used to estimate relative risk (RR) with 95% confidence interval (CI). In total, 1,674 offspring (35.3%) developed chronic musculoskeletal pain during the follow-up period of approximately 11 years. Both maternal (RR: 1.26, 95% CI: 1.03, 1.55) and paternal chronic musculoskeletal pain (RR: 1.29, 95% CI: 1.06, 1.57) was associated with increased risk of offspring chronic musculoskeletal pain. Compared to offspring of parents without chronic musculoskeletal pain, the adverse effect of parental pain was somewhat stronger among offspring who reported a low (RR: 1.82, 95% CI: 1.32, 2.52) versus high (RR: 1.32, 95% CI: 0.95, 1.84) level of leisure time physical activity. Offspring of parents with chronic musculoskeletal pain and who were classified as obese had more than twofold increased risk (RR: 2.33, 95% CI: 1.68, 3.24) of chronic musculoskeletal pain compared to normal weight offspring of parents without pain. In conclusion, parental chronic musculoskeletal pain is positively associated with risk of chronic musculoskeletal pain in their adult offspring. Maintenance of normal body weight may reduce the risk of chronic musculoskeletal pain in offspring of pain-afflicted parents.

Compared to offspring of parents without chronic musculoskeletal pain, the adverse effect of parental pain was somewhat stronger among offspring who reported a low (RR: 1.82, 95% CI: 1.32, 2.52) versus high (RR: 1.32, 95% CI: 0.95, 1.84) level of leisure time physical activity. Offspring of parents with chronic musculoskeletal pain and who were classified as obese had more than twofold increased risk (RR: 2.33, 95% CI: 1.68, 3.24) of chronic musculoskeletal pain compared to normal weight offspring of parents without pain. In conclusion, parental chronic musculoskeletal pain is positively associated with risk of chronic musculoskeletal pain in their adult offspring. Maintenance of normal body weight may reduce the risk of chronic musculoskeletal pain in offspring of pain-afflicted parents. PMID:27082110

Relation of attitude toward body elimination to parenting style and attitude toward the body.

Corgiat, Claudia A; Templer, Donald I

The purpose was to estimate the relation of attitude toward body elimination in 93 college students (27 men and 66 women), to authoritarian personality features, participants' perception of their mothers' parenting style, and attitudes toward cleanliness, sex, and family nudity. Subjects were administered the Body Elimination Attitude Scale, the Four-item F Scale, the Parental Authority Questionnaire Pertaining to Mothers, and the items "Sex is dirty," "Cleanliness is next to godliness," and "Children should never see other family members nude." Larger scores for disgust toward body elimination were associated with authoritarian personality characteristics, being less likely to describe mother's parenting style as authoritative (open communication) and more likely to describe it as authoritarian and lower scores for tolerance for family nudity. Implications for further research were suggested.

Validity of parent-reported weight and height of preschool children measured at home or estimated without home measurement: a validation study

PubMed Central

2011-01-01

Background Parental reports are often used in large-scale surveys to assess children's body mass index (BMI). Therefore, it is important to know to what extent these parental reports are valid and whether it makes a difference if the parents measured their children's weight and height at home or whether they simply estimated these values. The aim of this study is to compare the validity of parent-reported height, weight and BMI values of preschool children (3-7 y-old), when measured at home or estimated by parents without actual measurement. Methods The subjects were 297 Belgian preschool children (52.9% male). Participation rate was 73%. A questionnaire including questions about height and weight of the children was completed by the parents. Nurses measured height and weight following standardised procedures. International age- and sex-specific BMI cut-off values were employed to determine categories of weight status and obesity. Results On the group level, no important differences in accuracy of reported height, weight and BMI were identified between parent-measured or estimated values. However, for all 3 parameters, the correlations between parental reports and nurse measurements were higher in the group of children whose body dimensions were measured by the parents. Sensitivity for underweight and overweight/obesity were respectively 73% and 47% when parents measured their child's height and weight, and 55% and 47% when parents estimated values without measurement. Specificity for underweight and overweight/obesity were respectively 82% and 97% when parents measured the children, and 75% and 93% with parent estimations. Conclusions Diagnostic measures were more accurate when parents measured their child's weight and height at home than when those dimensions were based on parental judgements. When parent-reported data on an individual level is used, the accuracy could be improved by encouraging the parents to measure weight and height of their children at home. PMID:21736757

Factors associated with parental use of restrictive feeding practices to control their children's food intake.

There is a critical need to identify risk factors that make parents more likely to restrict their child's food intake. Child weight and ethnicity, parent weight, parent body dissatisfaction, and parent concern of child weight were examined as correlates of parent use of restrictive feeding practices in a diverse sample of 191 youth (ages 7-17). Participants attending a pediatric outpatient visit completed the Child Feeding Questionnaire (parent feeding practices and beliefs), the Figure Rating Scale (body dissatisfaction) and a demographic form. Parent BMI and child degree of overweight were calculated. Parent use of restrictive feeding practices was positively associated with parent BMI and was moderated by parent body dissatisfaction. Parent concern of child weight mediated the relationship between increasing child degree of overweight and parent use of restrictive feeding practices. There were no differences by child gender or ethnicity in parent use of restrictive feeding practices. These preliminary findings highlight the importance of assessing for underlying parent motivations for utilizing restrictive feeding practices and may help to identify and intervene with families at-risk for engaging in counterproductive weight control strategies. Continued identification of correlates of parent use of restrictive feeding practices is needed across child development and among individuals from diverse backgrounds.

About Tagish Lake as a Potential Parent Body for Polar Micrometeorites; Clues from their Hydrogen Isotopic Compositions

Engrand, C.; Gounelle, M.; Zolensky, M. E.; Duprat, J.

2003-01-01

The origin of the Antarctic micrometeorites (AMMs) is still a matter of debate. Their closest meteoritic counterparts are the C2 chondrites, but the match is not perfect, and the parent body(ies) of the AMMs is(are) still to be identified. Tagish Lake is a new meteorite fall which bears similarity with CI1 and CM2 chondrites, but is distinct from both. Based on the mineralogy of phyllosilicates, Noguchi et al. proposed that the phyllosilicate-rich AMMs and the Tagish Lake meteorites could derive from similar asteroids. The hydrogen isotopic compositions of extra-terrestrial samples can be used to get some insight on their origin. The D/H ratios of AMMs and of Tagish Lake have been measured, but using different analytical techniques. They are therefore not directly comparable. We performed additional hydrogen isotopic analyses of fragments of Tagish Lake using the same experimental setup previously used for the measurement of the hydrogen isotopic composition of AMMs. In this work, we could also analyze separately both lithologies of Tagish Lake (carbonate-poor and -rich). The distributions of delta D values measured in the two lithologies of Tagish Lake are very similar, indicating that fluids with similar hydrogen isotopic compositions altered the meteorite on the parent body for the two lithologies. Yet, the hydrogen isotopic composition of Tagish Lake is different from that of AMMs, suggesting that they do not derive from the same parent body.

Core Problem: Does the CV Parent Body Magnetization require differentiation?

O'Brien, T.; Tarduno, J. A.; Smirnov, A. V.

Evidence for the presence of past dynamos from magnetic studies of meteorites can provide key information on the nature and evolution of parent bodies. However, the suggestion of a past core dynamo for the CV parent body based on the study of the Allende meteorite has led to a paradox: a core dynamo requires differentiation, evidence for which is missing in the meteorite record. The key parameter used to distinguish core dynamo versus external field mechanisms is absolute field paleointensity, with high values (>>1 μT) favoring the former. Here we explore the fundamental requirements for absolute field intensity measurement in the Allende meteorite: single domain grains that are non-interacting. Magnetic hysteresis and directional data define strong magnetic interactions, negating a standard interpretation of paleointensity measurements in terms of absolute paleofield values. The Allende low field magnetic susceptibility is dominated by magnetite and FeNi grains, whereas the magnetic remanence is carried by an iron sulfide whose remanence-carrying capacity increases with laboratory cycling at constant field values, indicating reordering. The iron sulfide and FeNi grains are in close proximity, providing mineralogical context for interactions. We interpret the magnetization of Allende to record the intense early solar wind with metal-sulfide interactions amplifying the field, giving the false impression of a higher field value in some prior studies. An undifferentiated CV parent body is thus compatible with Allende's magnetization. Early solar wind magnetization should be the null hypothesis for evaluating the source of magnetization for chondrites and other meteorites.

Controlling parental feeding practices and child body composition in ethnically and economically diverse preschool children.

2014-02-01

Controlling parental feeding practices may be associated with childhood overweight, because coercive or intrusive feeding practices may negatively impact children's development of self-regulation of eating. This study examined pressuring or forcing a child (healthy or unhealthy foods) and restricting child from unhealthy or snack foods as two types of controlling feeding practices that explain unique variances in measures of child body composition (BMI, percent body fat, and parental perception of child weight). In an ethnically and economically diverse sample of 243 children aged 4-6years old and their biological parents (89% biological mothers, 8% biological fathers, and 3% step or grand-parent), descriptive statistics indicate ethnic and family income differences in measures of feeding practices and child body composition. Additionally, the two "objective" indices of body composition (BMI and percent body fat) were related to low pressure to eat, whereas the "subjective" index (perceived child weight) was related to restriction. Regression analyses accounting for ethnic and family income influences indicate that pressure to eat and restriction both explained unique variances in the two "objective" indices of body composition, whereas only restriction explained variance in perceived child weight. Findings have implications for helping parents learn about feeding practices that promote children's self-regulation of eating that simultaneously serves as an obesity prevention strategy.

The face of appearance-related social pressure: gender, age and body mass variations in peer and parental pressure during adolescence.

Appearance-related social pressure plays an important role in the development of a negative body image and self-esteem as well as severe mental disorders during adolescence (e.g. eating disorders, depression). Identifying who is particularly affected by social pressure can improve targeted prevention and intervention, but findings have either been lacking or controversial. Thus the aim of this study is to provide a detailed picture of gender, weight, and age-related variations in the perception of appearance-related social pressure by peers and parents. 1112 German students between grades 7 and 9 (mean age: M = 13.38, SD = .81) filled in the Appearance-Related Social Pressure Questionnaire (German: FASD), which considers different sources (peers, parents) as well as various kinds of social pressure (e.g. teasing, modeling, encouragement). Girls were more affected by peer pressure, while gender differences in parental pressure seemed negligible. Main effects of grade-level suggested a particular increase in indirect peer pressure (e.g. appearance-related school and class norms) from early to middle adolescence. Boys and girls with higher BMI were particularly affected by peer teasing and exclusion as well as by parental encouragement to control weight and shape. The results suggest that preventive efforts targeting body concerns and disordered eating should bring up the topic of appearance pressure in a school-based context and should strengthen those adolescents who are particularly at risk - in our study, girls and adolescents with higher weight status. Early adolescence and school transition appear to be crucial periods for these efforts. Moreover, the comprehensive assessment of appearance-related social pressure appears to be a fruitful way to further explore social risk-factors in the development of a negative body image.

Predominant approaches to teen pregnancy focus on decreasing numbers of teen mothers, babies born to them, and state dollars spent to support their families. This overshadows the structural violence interwoven into daily existence for these young parents. This paper argues for the increased use of participatory visual methods to compliment traditional research methods in shifting notions of what counts as evidence in response to teen pregnancy and parenting. We present the methods and results from a body mapping workshop as part of 'Hear Our Stories: Diasporic Youth for Sexual Rights and Justice', a project that examines structural barriers faced by young parenting Latinas and seeks to develop relevant messaging and programming to support and engage youth. Body mapping, as an engaging, innovative participatory visual methodology, involves young parenting women and other marginalised populations in drawing out a deeper understanding of sexual health inequities. Our findings highlight the ways body mapping elicits bodies as evidence to understand young motherhood and wellbeing.

Small-scale dust structures in Halley's coma. II. Disintegration of large dust bodies

NASA Astrophysics Data System (ADS)

Oberc, P.

2004-10-01

Small-scale dust structures, SDSs, altogether ˜35 events with extent ˜30-220 km, have been recognized owing to electric field records, mostly near the closest approach of Vega-2 to Halley's nucleus. Several (8-9) morphological forms of SDS have been identified, and all they make one family. Among the family members, the key form (with respect to which, all other forms can be regarded as degenerate) is a sequence of 3-5 dust clouds. The morphological forms represent various Vega-2 passes through SDSs at different stages of development. SDSs observable as the key form consisted of several fairly regularly spaced dust subpopulations, whose plane of symmetry was parallel to the comet orbit plane. That regularity together with specific features of morphological forms strongly constrain disintegration scenarios and dynamics of fragments, and allow to draw a number of conclusions, the main of which are: SDS parent bodies were ice-free dust aggregates lifted from the nucleus near the comet perihelion, whose masses were in the range ˜0.1-1 of the biggest emitted mass (mass of a body accelerated to the escape velocity, i.e., ˜300-1500 kg); the disintegration scenario comprised a few steps, and the first-step disintegration consisted mainly in consecutive detachments of biggest first-step fragments (BF-SFs) from the parent body; a SDS observable as the key form included the dust minitail of parent body and a few BF-SF minitails, the former one being longer than the latter ones; SDS parent bodies had a fractal-like internal structure, and the BF-SF mass was a few percent of the parent body mass; the thermal conductivity of SDS parent body was less than ˜0.4 W m -1 K -1 or so, while the latent heat of gluing organics was roughly 80 kJ mol -1; the disintegration mechanism was a combination of sintering and sublimation of organics. The multistep disintegration of SDS parent bodies can be reconciled with the basically one-step disintegration of aggregates responsible for the dust boundary (Oberc, P., Icarus 1996, 124, 195-208). The fractal-like structure and the relation between BF-SF mass and parent body mass are in agreement with predictions from the Weidenschilling model of comet formation. Large ice-free dust bodies, in particular SDS parent bodies, can be identified with refractory boulders postulated by some comet nucleus models.

There is a scarcity of resources and studies that utilize targeted weight management interventions to engage parents via mHealth tools targeting obese children and adolescents with mild intellectual disabilities (MIDs) extended from school to a home setting. To test the feasibility and acceptability of a school-based weight program (SBWMP) involving parents via mHealth tools designed to reduce weight, enhance knowledge and adopt healthy lifestyles, and thereby achieve better psychosocial well-being among children and adolescents with MIDs. Four special schools were randomly assigned as intervention or control schools. Students from the intervention group (n = 63) were compared to those in the control group (n = 52), which comprised those with usual school planned activities and no parental involvement. Demographics were considered as covariates in a general linear model, an ordinal regression model and a binary logistic regression model analyzing the relationships between the SBWMP and the outcome variables at baseline (T0) and six months later (T1). Body weight, body mass index, and triceps and subscapular skinfold thickness were lower in the intervention group compared to the control group, although the differences were not statistically significant. There was a positive and direct impact of the SBWMP on students’ health knowledge and psychological impacts in the intervention group. The SBWMP extended to the home involving parents via mHealth tools is a feasible and acceptable program for this group with MIDs and their parents. PMID:28981460

"A little on the heavy side": a qualitative analysis of parents' and grandparents' perceptions of preschoolers' body weights.

Parents' difficulties in perceiving children's weight status accurately pose a barrier for family-based obesity interventions; however, the factors underlying weight misinterpretation still need to be identified. This study's objective was to examine parents and grandparents' perceptions of preschoolers' body sizes. Interview questions also explored perceptions of parental responsibility for childhood obesity and appropriate contexts in which to discuss preschoolers' weights. Semistructured interviews, which were videotaped, transcribed and analysed qualitatively. Eugene and the Springfield metropolitan area, Oregon, USA PARTICIPANTS: Families of children aged 3-5 years were recruited in February-May 2011 through advertisements about the study, published in the job seekers' sections of a classified website (Craigslist) and in a local newspaper. 49 participants (22 parents and 27 grandparents, 70% women, 60% with overweight/obesity) from 16 low-income families of children aged 3-5 years (50% girls, 56% with overweight/obesity) were interviewed. There are important gaps between clinical definitions and lay perceptions of childhood obesity. While parents and grandparents were aware of their preschoolers' growth chart percentiles, these measures did not translate into recognition of children's overweight or obesity. The participants spoke of obesity as a problem that may affect the children in the future, but not at present. Participants identified childhood obesity as being transmitted from one generation to the next, and stigmatised it as resulting from 'lazy' parenting. Parents and grandparents avoided discussing the children's weights with each other and with the children themselves. The results suggest that clinicians should clearly communicate with parents and grandparents about the meaning and appearance of obesity in early childhood, as well as counteract the social stigma attached to obesity, in order to improve the effectiveness of family-based interventions to manage obesity in early childhood.

The role of S in the evolution of the parental cores of the iron meteorites

Kracher, A.; Wasson, J. T.

1982-01-01

The S contents of iron meteorite parent bodies are estimated on the basis of cosmochemical relationships to undifferentiated meteorites, the results are compared to observations on the major magmatic iron meteorite groups, and evidence is presented that S/Ni ratios in their parent melts were much lower than those inferred for the parent body. Several alternative models to account for the discrepancy are offered, including volatilization of S from the IIAB parent body, liquid immiscibility, and metastable liquid layers produced by episodic melting. Finally, the fate of the S-rich meteoroidal material is discussed, as well as the question of why it seems to be missing from meteorite collections.

Indulgent feeding style and children's weight status in preschool.

The primary aim of this study was to examine whether parent affect and child temperament characteristics differ across feeding styles in low-income families, given suggestive evidence. The secondary aim was to examine whether feeding styles were still related to children's body mass index independent of parent affect, child temperament, and known correlates. Participants in this study were 718 parents of children attending Head Start programs across two sites (Texas and Alabama). Parents were categorized into feeding styles of authoritative (n = 118), authoritarian (n = 219), indulgent (n = 240) and uninvolved (n = 141) using a parent-report questionnaire characterizing feeding in a general parenting paradigm. Parents completed questionnaires and measured height and weight was obtained from parents and children. Differences were found across feeding styles on parent affect and child temperament characteristics. Indulgent parents reported lower Negative Affect for themselves and lower Negative Affectivity for their children. The indulgent feeding style was significantly associated with higher child body mass index after controlling for parent affect, child temperament, and correlates (ethnicity, child age, parent body mass index). The results of this study not only show a robust association between the indulgent feeding style and weight status of low-income preschool children, but also suggest how congruence between parent emotional affect and child temperament characteristics may contribute to excess consumption among children of indulgent parents.

Information regarding associations between types of away-from-home family meal sources and obesity and other chronic diseases could help guide dietitians. The present study describes the purchase frequency of away-from-home food sources for family dinner (fast food, other restaurant purchases, home delivery, and take-out foods) and associations with weight status and percent body fat among adolescents (n=723) and parents (n=723) and related biomarkers of chronic disease among adolescents (n=367). A cross-sectional study design was used with baseline parent surveys and anthropometry/fasting blood samples from two community-based obesity studies (2006–2008) in Minnesota. Logistic regression and general linear modeling assessed associations between frequency of family dinner sources (weekly versus none in past week) and outcomes (parent and adolescent overweight/obesity and percent body fat; adolescent metabolic risk cluster z-score (MRC), cholesterol, HDL-C, LDL, triglycerides, fasting glucose, insulin and systolic blood pressure. Models accounted for clustering and adjusted for study allocation, baseline meal frequency and demographic characteristics. The odds of overweight/obesity were significantly greater when families reported at least one away-from-home dinner purchase in the past week (OR=1.2–2.6). Mean percent body fat, MRC z-scores and insulin levels were significantly greater with weekly purchases of family dinner from fast food restaurants (p’s < .05). Mean percent body fat, MRC z-scores and HDL levels were significantly higher for families who purchased weekly family dinner from take-out sources (p’s < .05). Although frequent family dinners may be beneficial for adolescents, the source of dinners is likely as important in maintaining a healthy weight. Interventions should focus on encouragement of healthful family meals. PMID:22117665

The extent to which general parenting represents feeding styles in ethnically diverse populations is not well documented. Existing measures of child feeding have focused almost exclusively on specific behaviors of European-American parents. A valid and reliable instrument was developed to identify feeding styles in parents of low-income minority preschoolers. Two hundred thirty-one parents (130 Hispanic; 101 African-American) completed questionnaires on feeding practices and parenting styles. Based on self-reported feeding behavior, parents were assigned to four feeding styles (authoritarian, n=84; authoritative, n=34; indulgent, n=80; and uninvolved, n=33). Convergent validity was evaluated by relating feeding styles to independent measures of general parenting and authoritarian feeding practices. Authoritarian feeding styles were associated with higher levels of general parental control and authoritarian feeding practices. Alternatively, authoritative feeding styles were associated with higher levels of general parental responsiveness. Among the two permissive feeding styles, Hispanic parents were more likely to be indulgent, whereas African-American parents were more likely to be uninvolved. Further, differences were found among the feeding styles on an independent measure of child's body mass index.

How is this child feeling? Preschool-aged children’s ability to recognize emotion in faces and body poses

2016-01-01

The study examined children’s recognition of emotion from faces and body poses, as well as gender differences in these recognition abilities. Preschool-aged children (N = 55) and their parents and teachers participated in the study. Preschool-aged children completed a web-based measure of emotion recognition skills, which included five tasks (three with faces and two with bodies). Parents and teachers reported on children’s aggressive behaviors and social skills. Children’s emotion accuracy on two of the three facial tasks and one of the body tasks was related to teacher reports of social skills. Some of these relations were moderated by child gender. In particular, the relationships between emotion recognition accuracy and reports of children’s behavior were stronger for boys than girls. Identifying preschool-aged children’s strengths and weaknesses in identification of emotion from faces and body poses may be helpful in guiding interventions with children who have problems with social and behavioral functioning that may be due, in part, to emotional knowledge deficits. Further developmental implications of these findings are discussed. PMID:27057129

Aerodynamic Analysis of Tektites and Their Parent Bodies

Experiment and analysis indicate that the button-type australites were derived from glassy spheres which entered or re-entered the atmosphere as cold solid bodies; in case of average-size specimens, the entry direction was nearly horizontal and the entry speed between 6.5 and 11.2 km/sec. Terrestrial origin of such spheres is impossible because of extremely high deceleration rates at low altitudes. The limited extension of the strewn fields rules out extraterrestrial origin of clusters of such spheres because of stability considerations for clusters in space. However, tektites may have been released as liquid droplets from glassy parent bodies ablating in the atmosphere of the earth. The australites then have skipped together with the parent body in order to re-enter as cold spheres. Terrestrial origin of a parent body would require an extremely violent natural event. Ablation analysis shows that fusion of opaque siliceous stone into glass by aerodynamic heating is impossible.

The classification of meteorites is commonly determined using isotopes, modal mineralogy, and bulk compositions [1]. Bulk rare earth elements (REEs) in meteorites are additionally utilized to understand parent body processes. Numerous authors have shown that chondritic groups exhibit REE patterns that may be attributable to their parent bodies [e.g. 2-4], and variations in abundances and concentrations of REEs may reflect early nebular processes, thermal metamorphism, and aqueous alteration on the parent body [5-6].

Evidence for Subsolidus Metasomatism in the Eucrite Parent Body

McCallum, I. Stewart; Schwartz, Jeffrey M.; Mullen, Emily K.

2004-01-01

The eucrite parent body (4Vesta) was continuously and rapidy resurfaced by basaltic lavas that formed the non-cumulate eucrites. Ophitic and variolitic textures have been preserved even though eucrites exhibit varying degrees of equilibration based on the extent of thermal metamorphism. Types range from least metamorphosed (type 1) to most metamorphosed (type 7) based in part on the interpretation of textures and compositional zoning profiles within pigeonitic pyroxenes. To provide constraints on the source and duration of the heating event responsible for metamorphism we have investigated primary and secondary textural and compositional relations in noncumulate eucrites with emphasis on subsolidus textures developed in pyroxenes. We have studied examples of most metamorphic types including Pasamonte (type 2) Stannern (4), Nuevo Laredo (4), Juvinas (5), Lakangaon (5), Millbillillie (6), Palo Blanco Creek (7), Jonzac (7), Haraiya (7), along with the cumulate eucrites Moama and Moore County.

Although it is difficult to explain exactly how eucrites and diogenites are related through simple magmatic processes, their shared oxygen isotopic compositions and the common occurrence of clasts of both lithologies in howardite breccias support derivation from a common parent body. For decades, HED meteorites have been linked to asteroid 4 Vesta, based on spectral similarities [1] and the discovery of a dynamical family (Vestoids) that provides a bridge between Vesta and nearby resonance escape hatches [2]. Although recently derived constraints on the rapidity of HED parent body differentiation, based on measurements of Al-26 in diogenites, have been used to argue against the Vesta-HED connection [3], new thermal evolution models [e.g., 4] appear to be heated and melted fast enough to account for this constraint. Data from the Dawn orbiter strengthen the Vesta - HED linkage and provide new insights into petrogenetic interpretations of these meteorites.

Parental feeding practices have been linked to eating and weight status in young children; however, more research is needed to understand what influences these feeding practices. The aim of this study was to examine how parental feeding practices that are linked to unhealthy eating patterns in young children, are related to parental body image and eating knowledge, attitudes, and behaviours . Participants were 330 mothers of a 2- to 6-year-old child. Mothers completed measures of knowledge of child body image and eating patterns, overvaluation of weight and shape, internalization of general media and athletic ideals, dieting, and parental feeding practices. Higher maternal knowledge of strategies to promote positive child body image and eating patterns predicted lower weight restriction, instrumental, emotional, and pushing to eat feeding practices. Overvaluation of weight and shape predicted use of fat restriction. Maternal internalization of the athletic ideal predicted instrumental and pushing to eat feeding practices. As these feeding practices have been associated with long-term risk of children's weight gain and/or disordered eating, these findings highlight the need for prevention interventions to target knowledge, attitudes, and behaviours of parents of pre-schoolers.

Thøgersen-Ntoumani, Cecilie; Ntoumanis, Nikos; Nikitaras, Nikitas

2010-06-01

This study used self-determination theory (Deci, E.L., & Ryan, R.M. (2000). The 'what' and 'why' of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11, 227-268.) to examine predictors of body image concerns and unhealthy weight control behaviours in a sample of 350 Greek adolescent girls. A process model was tested which proposed that perceptions of parental autonomy support and two life goals (health and image) would predict adolescents' degree of satisfaction of their basic psychological needs. In turn, psychological need satisfaction was hypothesised to negatively predict body image concerns (i.e. drive for thinness and body dissatisfaction) and, indirectly, unhealthy weight control behaviours. The predictions of the model were largely supported indicating that parental autonomy support and adaptive life goals can indirectly impact upon the extent to which female adolescents engage in unhealthy weight control behaviours via facilitating the latter's psychological need satisfaction.

Lifestyle Triple P: a parenting intervention for childhood obesity

PubMed Central

2012-01-01

Background Reversing the obesity epidemic requires the development and evaluation of childhood obesity intervention programs. Lifestyle Triple P is a parent-focused group program that addresses three topics: nutrition, physical activity, and positive parenting. Australian research has established the efficacy of Lifestyle Triple P, which aims to prevent excessive weight gain in overweight and obese children. The aim of the current randomized controlled trial is to assess the effectiveness of the Lifestyle Triple P intervention when applied to Dutch parents of overweight and obese children aged 4–8 years. This effectiveness study is called GO4fit. Methods/Design Parents of overweight and obese children are being randomized to either the intervention or the control group. Those assigned to the intervention condition receive the 14-week Lifestyle Triple P intervention, in which they learn a range of nutritional, physical activity and positive parenting strategies. Parents in the control group receive two brochures, web-based tailored advice, and suggestions for exercises to increase active playing at home. Measurements are taken at baseline, directly after the intervention, and at one year follow-up. Primary outcome measure is the children’s body composition, operationalized as BMI z-score, waist circumference, and fat mass (biceps and triceps skinfolds). Secondary outcome measures are children’s dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, parental self-efficacy, and body composition of family members (parents and siblings). Discussion Our intervention is characterized by a focus on changing general parenting styles, in addition to focusing on changing specific parenting practices, as obesity interventions typically do. Strengths of the current study are the randomized design, the long-term follow-up, and the broad range of both self-reported and objectively measured outcomes.

Does life history shape sexual size dimorphism in anurans? A comparative analysis

PubMed Central

2013-01-01

Background The evolution of sexual size dimorphism (SSD) is likely constrained by life history. Using phylogenetic comparative methods, we examined correlations between SSD among anurans and their life history traits, including egg size, clutch size, mating combat, and parental care behaviour. We used sexual dimorphism index (SDI = Body-sizefemale /Body-sizemale –1) as the measurement for SSD. Body size, life history and phylogenetic data were collected from published literature. Data were analysed at two levels: all anuran species and within individual families. Results Female-biased SSD is the predominant form in anurans. SSD decreases along with the body size increase, following the prediction of Rensch’s rule, but the magnitude of decrease is very small. More importantly, female body size is positively correlated with both fecundity related traits, egg size and clutch size, and SDI is also positively correlated with clutch size, suggesting fecundity advantage may have driven the evolution of female body size and consequently leads to the evolution of female-biased SSD. Furthermore, the presence of parental care, male parental care in particular, is negatively correlated with SDI, indicating that species with parental care tend to have a smaller SDI. A negative correlation between clutch size and parental care further suggests that parental care likely reduces the fecundity selection pressure on female body size. On the other hand, there is a general lack of significant correlation between SDI and the presence of male combat behaviour, which is surprising and contradictory to previous studies. Conclusions We find clear evidence to support the ‘fecundity advantage hypothesis’ and the ‘parental care hypothesis’ in shaping SSD in anurans. Nevertheless, the relationships of both parental care and combat behaviour to the evolution of SSD are complex in anurans and the extreme diversity of life history traits may have masked some potential interesting relationships. Our study represents the most comprehensive study of SSD in anurans to date. PMID:23368708

Geochemistry and genesis of the angrites

The angrites Angra dos Reis, LEW86010, and LEW87051 are petrologically and compositionally similar achondrites. All angrites have high FeO/MnO ratios of 80-94 and very low CI normalized Na/Sm ratios of 0.001-0.003. High abundances of oxidized Fe and low abundances of moderately volatile Na most likely resulted from parent body processes, such as magmatic outgassing, rather than nebular processes. All angrites have fractionated Ca/Al ratios, with Angra dos Reis exhibiting the most extreme ratio (3.1 {times} CI). For Angra dos Reis, cumulus material may be the cause of the high Ca/Al ratio. Refractory element abundances of LEW86010 and LEW87051 show similarmore » patterns, while Angra dos Reis has both greater enrichments in these elements and more fractionated patterns. Compositional and petrologic constraints indicate that LEW86010 and LEW87051 are related via olivine control. The refractory element abundances and mg{number sign} of LEW86010 can be approximated by removal of olivine from LEW87051, suggesting that LEW86010 may be a residual melt from a LEW87051-like precursor. Alternatively, LEW87051 may have formed via olivine accumulation from a LEW86010-like precursor. The differences between the LEW86010-LEW87051 duo and Angra dos Reis suggest that either the angrite parent body was heterogeneous or that Angra dos Reis was formed on a separate parent body. Based on FeO/MnO ratios and normative mineralogies, the angrite parent body(ies) may be similar in bulk composition to one of the carbonaceous chondrite groups, particularly CI-CM-CO.« less

Purpose The primary aim of this study was to examine whether parent affect and child temperament characteristics differ across feeding styles in low-income families, given suggestive evidence. The secondary aim was to examine whether feeding styles were still related to children’s body mass index independent of parent affect, child temperament, and known correlates. Methods Participants in this study were 718 parents of childrens attending Head Start programs across two sites (Texas and Alabama). Parents were categorized into feeding styles of authoritative (n = 118), authoritarian (n = 219), indulgent (n = 240) and uninvolved (n = 141) using a parent-report questionnaire characterizing feeding in a general parenting paradigm. Parents completed questionnaires and measured height and weight was obtained from parents and children. Results Differences were found across feeding styles on parent affect and child temperament characteristics. Indulgent parents reported lower Negative Affect for themselves and lower Negative Affectivity for their children. The indulgent feeding style was significantly associated with higher child body mass index after controlling for parent affect, child temperament, and correlates (ethnicity, child age, parent body mass index). Conclusions The results of this study not only show a robust association between the indulgent feeding style and weight status of low-income preschool childrens, but also suggest how congruence between parent emotional affect and child temperament characteristics may contribute to excess consumption among children of indulgent parents.

Latino pregnant and parenting adolescents living in inner cities are one of the populations at risk for acquiring HIV. Although teen parenthood has been predominantly looked at with a focus on potential adverse physical, emotional, and socioeconomic outcomes for the mother and child; a growing body of literature has documented the strengths and resiliency of young parents. Respeto/Proteger: Respecting and Protecting Our Relationships is a culturally rooted couple-focused and asset-based HIV prevention program developed for young Latino parents. In this program, parental protectiveness (defined as the parent-child emotional attachment that positively influences parental behavior) is viewed as an intrinsic and developing critical factor that supports resiliency and motivates behavioral change. The primary purpose of this article is to describe the longitudinal randomized study evaluating the effect of this intervention on unprotected vaginal sex 6 months post intervention and to determine whether parental protectiveness had a moderating effect on the intervention. The unique features of our database allow for examination of both individual and couple outcomes. PMID:19824837

To address childhood obesity, several states and local school districts across the United States have adopted body mass index (BMI) measurement initiatives. This descriptive case study explored psychosocial, environmental, and behavioral factors among parents of sixth-grade students who received BMI Health Letters (BMIHLs) in one Florida County. A nonexperimental postintervention design was employed to gather quantitative data via self-report Likert-type questionnaire. Participants were parents/guardians of sixth-grade students attending one Hillsborough County public middle school (n = 76). Results indicate three main findings: (a) most parents in this study (67.4%) who discussed the BMIHL with their child reported their child as "very" or "somewhat" uncomfortable with the discussion; (b) some parents of normal weight (NW) children responded by taking their child to a medical professional to control their weight; and (c) more parents of at risk of overweight/overweight (AR/OW) children (vs. NW) reported greater concern about their child's weight, using food restriction and physical activity to control their child's weight, and giving negative weight-related comments/behaviors. This case study illustrates the importance of adapting and tailoring state mandated BMIHLs for parents based on child's BMI status.

Parents' nonstandard work schedules and child well-being: a critical review of the literature.

This paper provides a comprehensive review of empirical evidence linking parental nonstandard work schedules to four main child developmental outcomes: internalizing and externalizing problems, cognitive development, and body mass index. We evaluated the studies based on theory and methodological rigor (longitudinal data, representative samples, consideration of selection and information bias, confounders, moderators, and mediators). Of 23 studies published between 1980 and 2012 that met the selection criteria, 21 reported significant associations between nonstandard work schedules and an adverse child developmental outcome. The associations were partially mediated through parental depressive symptoms, low quality parenting, reduced parent-child interaction and closeness, and a less supportive home environment. These associations were more pronounced in disadvantaged families and when parents worked such schedules full time. We discuss the nuance, strengths, and limitations of the existing studies, and propose recommendations for future research.

Few interventions have evaluated the influence of parent health literacy (HL) status on weight-related child outcomes. This study explores how parent HL affects the reach, attendance, and retention of and outcomes in a 3-month multicomponent family-based program to treat childhood obesity (iChoose). This pre-post, quasiexperimental trial occurred in the Dan River Region, a federally designated medically underserved area. iChoose research protocol and intervention strategies were designed using an HL universal precautions approach. We used validated measures, standardized data collection techniques, and generalized linear mixed-effect parametric models to determine the moderation effect of parent HL on outcomes. No significant difference in HL scores were found between parents who enrolled their child in the study and those who did not. Of 94 enrolled parents, 34% were low HL, 49% had an annual household income of less than $25,000, and 39% had a high school education or less. Of 101 enrolled children, 60% were black, and the mean age was 9.8 (standard deviation, 1.3) years. Children of parents with both low and high HL attended and were retained at similar rates. Likewise, parent HL status did not significantly influence improvements in effectiveness outcomes (eg, child body mass index [BMI] z scores, parent BMI, diet and physical activity behaviors, quality of life), with the exception of child video game/computer screen time; low HL decreased and high HL increased screen time (coefficient = 0.52, standard error, 0.11, P < .001). By incorporating design features that attended to the HL needs of parents, children of parents with low HL engaged in and benefited from a family-based childhood obesity treatment program similar to children of parents with high HL.

Obesity has reached an epidemic level in America (National Center for Health Statistics [NCHS] 1999), and this epidemic is more acute for African Americans than for other groups of Americans. In this study, 44 parent-child dyads completed measurements of height, depression, and body fat composition. In addition, parents completed a demographic questionnaire, and instruments, which measured family functioning, parental psychopathology, child behavior, and cardiovascular risks. Several models emerged for predicting childhood and parental body mass index, parental depression, and child behavioral problems. Findings indicated a role for parental depression in childhood obesity. These findings are discussed in light of Bandura's Social Cognitive Theory, and the family's role in childhood obesity.

Purpose. The purpose of this research was to collect data to inform intervention strategies to optimise body composition in South African preschool children. Methods. Data were collected in urban and rural settings. Weight status, physical activity, and gross motor skill assessments were conducted with 341 3–6-year-old children, and 55 teachers and parents/caregivers participated in focus groups. Results. Overweight and obesity were a concern in low-income urban settings (14%), but levels of physical activity and gross motor skills were adequate across all settings. Focus group findings from urban and rural settings indicated that teachers would welcome input on leading activities to promote physical activity and gross motor skill development. Teachers and parents/caregivers were also positive about young children being physically active. Recommendations for potential intervention strategies include a teacher-training component, parent/child activity mornings, and a home-based component for parents/caregivers. Conclusion. The findings suggest that an intervention focussed on increasing physical activity and improving gross motor skills per se is largely not required but that contextually relevant physical activity and gross motor skills may still be useful for promoting healthy weight and a vehicle for engaging with teachers and parents/caregivers for promoting other child outcomes, such as cognitive development.

Cosmic-Ray-Exposure Ages of Diogenites and the Collisional History of the HED Parent Body or Bodies

Cosmic-ray-exposure ages of meteorites provide information on the collisional history of their parent bodies and the delivery mechanism of meteorites to Earth. The exposure-age distributions of ordinary chondrites show distinct patterns for H, L, and LL types, consistent with their origin on different parent bodies. The exposure-age distributions of howardites, eucrites. and diogenites (HEDS) show a common pattern with major peaks at 22 Ma and 38 Ma This provides additional evidence for a common origin of the HED meteorites, possibly 4 Vesta, although orbital dynamics calculations showed that the delivery of meteorites from Vesta to Earth is difficult. However, the discovery of several kilometer-sized Vesta-like asteroids in the region between Vesta and the 3:1 resonance suggested that these seem more likely parent bodies of the HEDs than Vesta itself. This implies that the exposure-age clusters may represent samples of several parent bodies. Therefore, the near-absence of diogenites with ages <20 Ma might be of interest for the composition of these kilometer-sized fragments of Vesta. Here we present cosmic-ray-exposure ages of 20 diogenites, including 9 new meteorites. In addition, we calculate the probability for each peak to occur by chance, assuming a constant production rate of HED fragments.

Parent-focused treatment for adolescent anorexia nervosa: a study protocol of a randomised controlled trial

PubMed Central

2014-01-01

Background Family-based treatment is an efficacious outpatient intervention for medically stable adolescents with anorexia nervosa. Previous research suggests family-based treatment may be more effective for some families when parents and adolescents attend separate therapy sessions compared to conjoint sessions. Our service developed a novel separated model of family-based treatment, parent-focused treatment, and is undertaking a randomised controlled trial to compare parent-focused treatment to conjoint family-based treatment. Methods/Design This randomised controlled trial will recruit 100 adolescents aged 12–18 years with DSM-IV anorexia nervosa or eating disorder not otherwise specified (anorexia nervosa type). The trial commenced in 2010 and is expected to be completed in 2015. Participants are recruited from the Royal Children’s Hospital Eating Disorders Program, Melbourne, Australia. Following a multidisciplinary intake assessment, eligible families who provide written informed consent are randomly allocated to either parent-focused treatment or conjoint family-based treatment. In parent-focused treatment, the adolescent sees a clinical nurse consultant and the parents see a trained mental health clinician. In conjoint family-based treatment, the whole family attends sessions with the mental health clinician. Both groups receive 18 treatment sessions over 6 months and regular medical monitoring by a paediatrician. The primary outcome is remission at end of treatment and 6 and 12 month follow up, with remission defined as being ≥ 95% expected body weight and having an eating disorder symptom score within one standard deviation of community norms. The secondary outcomes include partial remission and changes in eating pathology, depressive symptoms and self-esteem. Moderating and mediating factors will also be explored. Discussion This will be first randomised controlled trial of a parent-focused model of family-based treatment of adolescent anorexia nervosa. If found to be efficacious, parent-focused treatment will offer an alternative approach for clinicians who treat adolescents with anorexia nervosa.

Evolution of carbonaceous chondrite parent bodies: Insights into cometary nuclei

NASA Technical Reports Server (NTRS)

Mcsween, Harry Y., Jr.

1989-01-01

It is thought that cometary samples will comprise the most primitive materials that are able to be sampled. Although parent body alteration of such samples would not necessarily detract from scientists' interest in them, the possibility exists that modification processes may have affected cometary nuclei. Inferences about the kinds of modifications that might be encountered can be drawn from data on the evolution of carbonaceous chondrite parent bodies. Observations suggest that, of all the classes of chondrites, these meteorites are most applicable to the study of comets. If the proportion of possible internal heat sources such as Al-26 in cometary materials are similar to those in chondrites, and if the time scale of comet accretion was fast enough to permit incorporation of live radionuclides, comets might have had early thermal histories somewhat like those of carbonaceous chondrite parent bodies.

On treating adolescent girls: focus on strengths and resiliency in psychotherapy.

Johnson, Norine G

2003-11-01

This strength-based psychotherapy with adolescent girls and their families is derived from feminist psychology, positive psychology, and strength-based interventions with teens. Research reviewed by the American Psychological Association's Presidential Task Force on Adolescent Girls formed the basis of specific interventions within this approach. Research findings that contributed are the effects on teen girls of positive parental relationships; utilizing strengths of their race, ethnicity, class, and gender; positive body images; being outspoken in relationships; problem-solving skills that foster independence; and family support for independence. The strength-based approach is illustrated by a case example of a 13-year-old European American girl with acting-out behaviors, depression, and subclinical attention-deficit/hyperactivity disorder. The case illustrates how to empower adolescent girls within therapy, when and how to include parents, how to change the focus to strengths, and how to help the parents assess and build upon their daughters' strengths.

1990-01-01

The major and trace elements were analyzed in samples of LEW86010, LEW87051, and Angra dos Reis angrites were analyzed using INAA and fused-bead EMP techniques. Results suggest that all three angrites originated on a volatile-depleted (Na-poor) but oxidized parent body or on several bodies. The combination of low Na and high FeO/MnO found in these samples suggests that the extreme Na depletion was caused by parent-body outgassing during differentiation, rather than by nebular processes. It was also found that the refractory-element abundances observed in LEW86010 and LEW87051 are related via olivine control; it is suggested that LEW86010 may be a residual melt from a LEW87051-like precursor or that LEW87051 formed from a LEW86010-like precursor via olivine accumulation. On the other hand, the Angra dos Reis displayed an unusual refractory element pattern suggesting that either the angrite parent body was heterogeneous or that Angra dos Reis was formed on a parent body different from that of the other two angrites.

Parental Views of Promoting Fruit and Vegetable Intake Among Overweight Preschoolers and School-Aged Children

Nepper, Martha J.; Chai, Weiwen

2017-01-01

Given the importance of parental influence on children’s eating habits, we explored perceptions of parents of overweight (body mass index–for-age percentile ≥85%) preschoolers (3-5 years) and overweight school-aged children (6-12 years) regarding challenges in promoting fruit and vegetable intake and how they and other family members influence their overweight children’s dietary habits. Focus groups were conducted with 13 parents of overweight preschoolers and 14 parents of overweight school-aged children. Codes and themes were developed by inductive data analysis. Four common themes were identified: short shelf life of fresh fruits and vegetables prohibiting parents from purchasing, children’s taste changes in fruits and vegetables, parents having the primary influence on children’s dietary intake, and wanting fruits and vegetables “ready to go.” Parents of school-aged children were more concerned about their children’s weight, and extended family members negatively influenced children’s dietary intake compared with parents of preschoolers. Our findings provide valuable insight for nutrition/health educators when developing family-based interventions for weight management. PMID:28462357

Triple oxygen isotopes in biogenic and sedimentary carbonates

The 17O anomaly (Δ17O) of natural waters has been shown to be sensitive to evaporation in a way analogous to deuterium excess, with evaporated bodies of water (e.g., leaf waters, lake waters, animal body waters) tending to have lower Δ17O than primary meteoric waters. In animal body water, Δ17O relates to the intake of evaporated waters, evaporative effluxes of water, and the Δ17O value of atmospheric O2, which itself carries signatures of global carbon cycling and photochemical reactions in the stratosphere. Carbonates have the potential to record the triple oxygen isotope compositions of parent waters, allowing reconstruction of past water compositions, but such investigations have awaited development of methods for high-precision measurement of Δ17O of carbonate. We describe optimized methods based on a sequential acid digestion/reduction/fluorination approach that yield Δ17O data with the high precision (∼0.010‰, 1σ) needed to resolve subtle environmental signals. We report the first high-precision Δ17O dataset for terrestrial carbonates, focusing on vertebrate biogenic carbonates and soil carbonates, but also including marine invertebrates and high-temperature carbonates. We determine apparent three-isotope fractionation factors between the O2 analyte derived from carbonate and the parent waters of the carbonate. These in combination with appropriate temperature estimates (from clumped isotope thermometry, or known or estimated body temperatures) are used to calculate the δ18O and Δ17O of parent waters. The clearest pattern to emerge is the strong 17O-depletion in avian, dinosaurian, and mammalian body water (from analyses of eggshell and tooth enamel) relative to meteoric waters, following expected influences of evaporated water (e.g., leaf water) and atmospheric O2 on vertebrate body water. Parent waters of the soil carbonates studied here have Δ17O values that are similar to or slightly lower than global precipitation. Our results suggest that Δ17O will have useful application to paleoenvironmental studies of continental environments where the effects of evaporation are important, and where vertebrate body water may record an isotopic signal of evaporated water sources and atmospheric oxygen.

This prospective, randomized, controlled trial for parents of overweight and obese 3- to 7-year-olds was performed to assess the feasibility of a program promoting healthy eating and lifestyle by targeting parents as agents of change. The intervention was composed of 6-in-person group sessions and a customized website over 12 months. The control group received customary care. The primary outcome was feasibility of the intervention to promote healthy behavior change measured by attendance. The secondary outcome was effectiveness assessed by attaining reduced body mass index (BMI) z scores, healthy behavior changes and increased parent self-efficacy. Seventy-three child-parent dyads were enrolled; 14 parents never attended any sessions. Participation in follow-up assessments did not meet the hypothesized level. Ultimate BMI z scores did not differ between control and intervention groups. Parenting skills did not improve in the intervention group. This intervention to achieve healthy lifestyle changes in children via their parents as "change agents" was unsuccessful.

The aim of this paper was to estimate the effect of maternal and paternal smoking on foetal death (miscarriage and stillbirth) and to estimate potential interactions with physical exercise and pre-pregnancy body mass index. We selected 87,930 pregnancies from the population-based Danish National Birth Cohort. Information about lifestyle, occupational, medical and obstetric factors was obtained from a telephone interview and data on pregnancy outcomes came from the Danish population based registries. Cox regression was used to estimate the hazard ratios (adjusted for potential confounders) for predominantly late foetal death (miscarriage and stillbirth). An interaction contrast ratio was used to assess potential effect measure modification of smoking by physical exercise and body mass index. The adjusted hazard ratio of foetal death was 1.22 (95 % CI 1.02-1.46) for couples where both parents smoked compared to non-smoking parents (miscarriage: 1.18, 95 % CI 0.96-1.44; stillbirth: 1.32, 95 % CI 0.93-1.89). On the additive scale, we detected a small positive interaction for stillbirth between smoking and body mass index (overweight women). In conclusion, smoking during pregnancy was associated with a slightly higher hazard ratio for foetal death if both parents smoked. This study suggests that smoking may increase the negative effect of a high BMI on foetal death, but results were not statistically significant for the interaction between smoking and physical exercise.

There is large body of knowledge to support the importance of early interventions to improve child health and development. Nonetheless, it is important to identify cost-effective blends of preventive interventions with adequate coverage and feasible delivery modes. The aim of the Children and Parents in Focus trial is to compare two levels of parenting programme intensity and rate of exposure, with a control condition to address impact and cost-effectiveness of a universally offered evidence-based parenting programme in the Swedish context. The trial has a cluster randomised controlled design comprising three arms: Universal arm (with access to participation in Triple P - Positive Parenting Program, level 2); Universal Plus arm (with access to participation in Triple P - Positive Parenting Program, level 2 as well as level 3, and level 4 group); and Services as Usual arm. The sampling frame is Uppsala municipality in Sweden. Child health centres consecutively recruit parents of children aged 3 to 5 years before their yearly check-ups (during the years 2013-2017). Outcomes will be measured annually. The primary outcome will be children's behavioural and emotional problems as rated by three informants: fathers, mothers and preschool teachers. The other outcomes will be parents' behaviour and parents' general health. Health economic evaluations will analyse cost-effectiveness of the interventions versus care as usual by comparing the costs and consequences in terms of impact on children's mental health, parent's mental health and health-related quality of life. This study addresses the need for comprehensive evaluation of the long-term effects, costs and benefits of early parenting interventions embedded within existing systems. In addition, the study will generate population-based data on the mental health and well-being of preschool aged children in Sweden. ISRCTN16513449.

The determinants of physical activity (PA) and body fatness in Chinese adolescents are rarely examined. This study aimed to investigate the effect of attitude toward PA, screen time, parents' socioeconomic status (SES), and exercise habit on PA and body fatness among Chinese children by using structural equation modeling (SEM) analysis. Data obtained from the second Community Fitness Survey in Hong Kong were utilized, in which students from one secondary school of each of the 18 districts of Hong Kong were recruited. A total of 2517 questionnaires with physical fitness items were successfully distributed to students aged 13-19 years in these districts. Families' SES, parents' exercise habit, children's intention to participate in PA, amount of moderate to vigorous PA (MVPA), screen time, children's attitude toward PA, and children's body fat percentage were measured and analyzed with SEM. The structural equation model was composed of a measurement model and a structural model. The model was tested with Mplus 6. The Chi-square test, root mean square error of approximation, comparative fit index, and Tucker-Lewis index were calculated to evaluate model fit. The model was then modified based on the model fit indices. Children's intention to participate in PA was a strong predictor of their engagement in MVPA. Parents' exercise habit had both direct and indirect (via attitude) effects on their children's intention to participate in PA. Screen time was not a predictor of body composition. Children's intention to participate in PA directly affected their body composition. Children's attitude toward PA, parents' exercise habit, and SES had significant effects on the children's intention to participate in PA. Furthermore, obesity had a negative effect on the children's attitude toward PA. To promote MVPA and prevent obesity in Chinese children of Hong Kong, it is important to design intervention that enhances children's intention and attitude in PA, as well as parent's exercise habits. Tailormade programs that take SES into consideration are also essential. Further studies are necessary to extend the results and test the model in other metropolitan areas in China.

The phenotypic effect of some single nucleotide polymorphisms (SNPs) depends on their parental origin. We present a novel approach to detect parent-of-origin effects (POEs) in genome-wide genotype data of unrelated individuals. The method exploits increased phenotypic variance in the heterozygous genotype group relative to the homozygous groups. We applied the method to >56,000 unrelated individuals to search for POEs influencing body mass index (BMI). Six lead SNPs were carried forward for replication in five family-based studies (of ∼4,000 trios). Two SNPs replicated: the paternal rs2471083-C allele (located near the imprinted KCNK9 gene) and the paternal rs3091869-T allele (located near the SLC2A10 gene) increased BMI equally (beta = 0.11 (SD), P<0.0027) compared to the respective maternal alleles. Real-time PCR experiments of lymphoblastoid cell lines from the CEPH families showed that expression of both genes was dependent on parental origin of the SNPs alleles (P<0.01). Our scheme opens new opportunities to exploit GWAS data of unrelated individuals to identify POEs and demonstrates that they play an important role in adult obesity.

Parenting challenges in the setting of terminal illness: a family-focused perspective.

In the advanced stages of illness, families with dependent children experience disruption across all dimensions of family life. The need for family support during palliative care is well recognized, yet little is understood about how parents and their children navigate these difficult circumstances. This review summarizes the current body of research on parenting challenges in advanced cancer. To date, the study of parental cancer has focused predominantly on the early stages of disease and its impact on children and adolescents. Less is known about how families with minor children prepare for parental loss. Evidence suggests that having dependent children influences parents' treatment decisions at the end of life, and that a central concern for children and parents is optimizing time spent together. Parents may feel an urgency to engage in accelerated parenting, and maintaining normalcy remains a consistent theme for the ill and healthy parent alike. There is a growing evidence base affirming the importance of responsive communication prior to death. Advancing knowledge about the parenting experience at the end of life is critical for ensuring effective support to the entire family, as it accommodates and prepares for the loss of a vital member.

Overweight in children and adolescents associated with TV viewing and parental weight: Project HeartBeat!

Parental obesity and TV viewing are risk factors for childhood obesity. This study assessed the association of children's TV viewing and computer use with body mass and examined whether parental weight status modified the association. Cross-sectional associations of parental weight status, hours of TV viewing and computer use, and children's body composition were studied in a subsample of 526 black and nonblack children, aged 8, 11, and 14 years at baseline, enrolled in Project HeartBeat!, a longitudinal study of cardiovascular disease risk factors, 1991-1995. BMI, fat-free mass (FFM), and percent body fat (PBF) were calculated from children's body composition measured at baseline. Children's TV viewing and computer use habits and parental height and weight were self-reported. Multivariate regression analysis was used in assessing inter-relations of parental weight status and child's TV viewing and computer use habits with BMI, FFM, PBF, and risk for overweight status (BMI > or =85th percentile), adjusting for age, gender, race, and Tanner stage. Children of one or two overweight/obese parents watched an average of 22+/-6 minutes or 30+/-11 minutes more TV per day than children of normal-weight parents, respectively (both p<0.01). In multivariate regression analyses, BMI and PBF increased significantly by 0.42 kg/m(2) and 1.14% (both p<0.001), respectively, for each hour of TV watched among children with overweight parents, but not for those with normal-weight parents (p(interaction)<0.05). Similar results were observed for total screen time. These study findings are consistent with a genetic contribution of parental weight; however, overweight/obese parents may also exhibit behavior patterns that negatively influence children's TV viewing and have an impact on child overweight status. The effect of parental BMI on children's BMI may have both a genetic and an environmental linkage.

Parental body mass index (BMI) is strongly linked with the development of offspring overweight and obesity. However, there are a limited number of studies focusing on the association of parental body mass index before pregnancy on offspring growth and body composition in early life, particularly in developing countries. Data from the University Sains Malaysia (USM) Pregnancy Cohort which consists of 153 mother-offspring pairs were used. Data were collected using interview-administered questionnaires and anthropometric measurements were also obtained. Multiple linear regression and generalised equation estimation (GEE) were used to examine the direction and impact of the association between parental BMI and child growth and body composition (weight for age, height for age, body mass index for age, weight for height and fat mass at age 2m, 6m, and 12m). Potential confounders, including validated measures of maternal diets and physical activity during pregnancy, were considered. Of 153 parents, one-quarter of the mothers and 42.2% of the fathers, respectively, were overweight or obese before pregnancy. A significant association was found between maternal BMI and child's weight for height z-score (WHZ) and body mass index for age z-score (BAZ). Having high pre-pregnancy BMI may increase BMI and WAZ of offspring in early life. Findings from this study emphasise the importance of monitoring maternal weight status, particularly before and during pregnancy and early life of offspring among Malaysians.

This pilot study tested the feasibility of Family-Based Hip-Hop to Health, a school-based obesity prevention intervention for 3–5 year old Latino children and their parents, and estimated its effectiveness in producing smaller average changes in body mass index at one year follow-up. Four Head Start preschools administered through the Chicago Public Schools were randomly assigned to receive a Family-Based Intervention (FBI) or a General Health intervention (GHI). Parents signed consent forms for 147 of the 157 children enrolled. Both the school-based and family-based components of the intervention were feasible, but attendance for the parent intervention sessions was low. Contrary to expectations, a downtrend in BMI Z score was observed in both the intervention and control groups. While the data reflect a downward trend in obesity among these young Hispanic children, obesity rates remained higher at one-year follow-up (15%) than those reported by the National Health and Nutrition Examination Survey (2009–2010) for 2–5 year old children (12.1%). Developing evidence-based strategies for obesity prevention among Hispanic families remains a challenge. PMID:23532990

Metal-rich meteorites from the aubrite parent body

Three metal-rich meteorites - Mt. Egerton, Horse Creek, and LEW 88055 - were studied and it is suggested that they formed in the aubrite parent body. LEW 85369 and 88631 may also have a common origin, but these rocks have not yet been studied in detail. This body was probably heated to about 1600 C by a very strong heat source. While molten, metal agglomerated into sizeable nodules which never segregated efficiently to form a core, but were trapped in the silicate mantle. Different clasts and lithologies in aubrites solidified and cooled under local equilibrium conditions of oxygen fugacity, and with different thermal histories. Impacts mixed clasts from throughout the parent body, creating the typical aubrite breccias.

Theoretical models of pediatric chronic pain propose longitudinal associations between children's pain experiences and parent and family factors. A large body of cross-sectional research supports these models, demonstrating that greater parent distress and maladaptive parenting behaviors are associated with greater child disability. Family-based cognitive-behavioral therapy interventions have been developed for youth with chronic pain which aim to improve child disability and reduce maladaptive parenting behaviors. However, little is known about temporal, longitudinal associations between parent and child functioning in this population. In the present study, we conducted a secondary analysis of data from 138 families of youth with chronic pain aged 11 to 17 years old who received family-based cognitive-behavioral therapy delivered through the Internet as part of a randomized controlled trial. Measures of child disability, parent protective behavior, and parent distress were obtained at pretreatment, immediate posttreatment, 6-month follow-up, and 12-month follow-up. Latent growth modeling indicated that child disability, parent protective behavior, and parent distress improved with treatment over the 12-month study period. Latent growth modeling for parallel processes indicated that higher parent distress at pretreatment predicted less improvement in child disability over 12 months. No other predictive paths between parent and child functioning were significant. These findings indicate that parent distress may increase the risk of poor response to psychological pain treatment among youth with chronic pain. At present, parent distress is not routinely targeted in psychological interventions for pediatric chronic pain. Research is needed to determine optimal strategies for targeting parent and family factors in the treatment of pediatric chronic pain.

Experimental Study of Serpentinization Reactions

Cohen, B. A.; Brearley, A. J.; Ganguly, J.; Liermann, H.-P.; Keil, K.

2004-01-01

Current carbonaceous chondrite parent-body thermal models [1-3] produce scenarios that are inconsistent with constraints on aqueous alteration conditions based on meteorite mineralogical evidence, such as phase stability relationships within the meteorite matrix minerals [4] and isotope equilibration arguments [5, 6]. This discrepancy arises principally because of the thermal runaway effect produced by silicate hydration reactions (here loosely called serpentinization, as the principal products are serpentine minerals), which are so exothermic as to produce more than enough heat to melt more ice and provide a self-sustaining chain reaction. One possible way to dissipate the heat of reaction is to use a very small parent body [e.g., 2] or possibly a rubble pile model. Another possibility is to release this heat more slowly, which depends on the alteration reaction path and kinetics.

Petrography of isotopically-dated clasts in the Kapoeta howardite and petrologic constraints on the evolution of its parent body

Results are presented for petrographic and electron microprobe studies of the isotopically dated A, B, C, and rho basaltic rock fragments separated from the howardite Kapoeta. Other lithic clasts and numerous mineral fragments in thin sections of Kapoeta are investigated in order to outline the range in lithology and chemistry of the source materials from which the Kapoeta meteorite is derived. The data obtained are compared to those from other meteorite and lunar samples, with particular reference to the observational consequences for the evolution of the Kapoeta parent body. A major conclusion is that there is no clearcut evidence for young magmatism on the Kapoeta parent body. The observations preclude the interpretation that the Kapoeta is a simple mixture of eucrites and diogenites. In contrast to the moon, a source of anorthositic rocks does not appear to have been present on the Kapoeta parent body which involved chiefly pyroxene. The FeO-MnO relationships suggest that the source of the materials in the Kapoeta parent planet are fundamentally related.

Expelled grains from an unseen parent body around AU Microscopii

NASA Astrophysics Data System (ADS)

Sezestre, É.; Augereau, J.-C.; Boccaletti, A.; Thébault, P.

Context. Recent observations of the edge-on debris disk of AU Mic have revealed asymmetric, fast outward-moving arch-like structures above the disk midplane. Although asymmetries are frequent in debris disks, no model can readily explain the characteristics of these features. Aims: We present a model aiming to reproduce the dynamics of these structures, more specifically their high projected speeds and their apparent position. We test the hypothesis of dust emitted by a point source and then expelled from the system by the strong stellar wind of this young M-type star. In this model we make the assumption that the dust grains follow the same dynamics as the structures, I.e., they are not local density enhancements. Methods: We perform numerical simulations of test particle trajectories to explore the available parameter space, in particular the radial location R0 of the dust producing parent body and the size of the dust grains as parameterized by the value of β (ratio of stellar wind and radiation pressure forces over gravitation). We consider the cases of a static and of an orbiting parent body. Results: We find that for all considered scenarios (static or moving parent body), there is always a set of (R0,β) parameters able to fit the observed features. The common characteristics of these solutions is that they all require a high value of β, of around 6. This means that the star is probably very active, and the grains composing the structures are submicronic in order for observable grains to reach such high β values. We find that the location of the hypothetical parent body is closer in than the planetesimal belt, around 8 ± 2 au (orbiting case) or 28 ± 7 au (static case). A nearly periodic process of dust emission appears, of 2 yr in the orbiting scenarios and 7 yr in the static case. Conclusions: We show that the scenario of sequential dust releases by an unseen point-source parent body is able to explain the radial behavior of the observed structures. We predict the evolution of the structures to help future observations discriminate between the different parent body configurations that have been considered. In the orbiting parent body scenario, we expect new structures to appear on the northwest side of the disk in the coming years.

A growing body of research suggests that children and adolescents who share frequent meals with their families report better nutrition indicators, family relationships and mental health. Yet, little research has examined whether parents who share meals with their families report the same indicators of wellbeing. The current paper addresses this question using population-based survey data and a sample of parents in the United States (n = 889, mean age 31 years) that responded to the fourth wave of the Project EAT study in 2015-16. Multiple regression models were used to examine associations between frequency of family meals and indicators of nutritional, social and emotional wellbeing, controlling for demographic and household characteristics. Analyses also examined if associations were moderated by sex, as mothers tend to be more responsible for household and childcare tasks. Results suggested that parent report of frequent family meals was associated with higher levels of family functioning, greater self-esteem, and lower levels of depressive symptoms and stress (p-value for all <0.001). Frequency of family meals was also related to greater fruit and vegetable consumption (both p < 0.05), but was unrelated to other indicators of parent body size and nutritional wellbeing. Associations between frequency of family meals and parent wellbeing were similar for both mothers and fathers. Findings from the current study suggest that frequent family meals may contribute to the social and emotional wellbeing of parents. Future strategies to promote family meals should consider the potential impacts on the health and wellbeing of the whole family. Copyright © 2018 Elsevier Inc. All rights reserved.

Maternal obesity may affect cardiovascular outcomes in the offspring. We examined the associations of maternal prepregnancy body mass index and gestational weight gain with childhood cardiac outcomes and explored whether these associations were explained by parental characteristics, infant characteristics or childhood body mass index. In a population-based prospective cohort study among 4852 parents and their children, we obtained maternal weight before pregnancy and in early, mid- and late pregnancy. At age 6 years, we measured aortic root diameter (cm) and left ventricular dimensions. We calculated left ventricular mass (g), left ventricular mass index (g m(-2.7)), relative wall thickness ((2 × left ventricular posterior wall thickness)/left ventricular diameter), fractional shorting (%), eccentric left ventricular hypertrophy and concentric remodeling. A one standard deviation score (SDS) higher maternal prepregnancy body mass index was associated with higher left ventricular mass (0.10 SDS (95% confidence interval (CI) 0.08, 0.13)), left ventricular mass index (0.06 SDS (95% CI 0.03, 0.09)) and aortic root diameter (0.09 SDS (95% CI 0.06, 0.12)), but not with relative wall thickness or fractional shortening. A one SDS higher maternal prepregnancy body mass index was associated with an increased risk of eccentric left ventricular hypertrophy (odds ratio 1.21 (95% CI 1.03, 1.41)), but not of concentric remodeling. When analyzing the effects of maternal weight in different periods simultaneously, only maternal prepregnancy weight and early pregnancy weight were associated with left ventricular mass, left ventricular mass index and aortic root diameter (P-values<0.05), independent of weight in other pregnancy periods. All observed associations were independent of parental and infant characteristics, but attenuated to non-significance after adjustment for childhood body mass index. Maternal prepregnancy body mass index and weight gain in early pregnancy are both associated with offspring cardiac structure in childhood, but these associations seem to be fully explained by childhood body mass index.

Differential sensitization of parenting on early adolescent cortisol: Moderation by profiles of maternal stress.

The hypothalamic-pituitary-adrenal (HPA) axis is a critical component of the body's stress-response neurobiological system, and its development and functioning are shaped by the social environment. Much of our understanding of the effects of the caregiving environment on the HPA axis is based on (a) parenting in young children and (b) individual maternal stressors, such as depression. Yet, less is known about how parenting behaviors and maternal stressors interact to influence child cortisol regulation, particularly in older children. With an ethnically diverse sample of 199 mothers and their early adolescent children (M=11.00years; 54% female), a profile analytic approach was used to investigate how multiple phenotypes of maternal stress co-occur and moderate the relation between parenting behaviors and youths' diurnal cortisol rhythms. Latent profile analysis yielded 4 profiles: current parenting stress, concurrent parenting and childhood stress, childhood stress, and low stress. For mothers with the concurrent parenting and childhood stress profile, inconsistent discipline, poor parental supervision, and harsh caregiving behaviors each were related to flattened diurnal cortisol rhythms in their adolescents. For mothers with the current parenting stress and childhood stress profiles, their use of inconsistent discipline was associated with flattened diurnal cortisol rhythms in their adolescents. For mothers with the low stress profile, none of the parenting behaviors was related to their adolescents' cortisol regulation. Findings suggest that based on mothers' stress profile, parenting behaviors are differentially related to youths' diurnal cortisol rhythms. Implications for parenting interventions are discussed.

To assess familial links in fat stereotypes and predictors of stereotypes among girls and their parents. Fat stereotypes were assessed using a questionnaire developed for this study. Participants indicated the extent to which they agreed with nine statements about thin people (e.g., thin people are smart) and the same statements about fat people (e.g., fat people are smart). Predictors of fat stereotypes that were examined include weight status (BMI; girls and parents), education (parents), income (parents), self-investment in physical appearance (parents), maladaptive eating attitudes (girls), and parenting practices and peer interactions focused on body shape and weight loss (girls). Girls and parents exhibited fat stereotypes. Fathers who were more educated and had a higher family income were more likely to endorse fat stereotypes, as were mothers and fathers with a high investment in their physical appearance. Although no associations were found between girls' and parents' fat stereotypes, girls were more likely to endorse fat stereotypes when interactions with parents and peers focused on body shape and weight loss. Girls were also more likely to endorse fat stereotypes when they reported higher levels of maladaptive eating attitudes. No associations were found between weight status and fat stereotypes. Although there was no association between girls' and parents' fat stereotypes, girls were more likely to express negative attitudes about obesity and obese persons when parenting practices and interactions with peers promoted a lean body type, suggesting that there may be an implicit link between the lean ideal and fat stereotypes.

Cystic fibrosis is a progressive disease requiring a complex, time-consuming treatment regimen. Nonadherence may contribute to an acceleration of the disease process. Spirituality influences some parental healthcare behaviors and medical decision-making. We hypothesized that parents of children with cystic fibrosis, when classified into groups based on adherence rates, would share certain psychosocial and religious and/or spiritual variables distinguishing them from other adherence groups. We conducted a multisite, prospective, observational study focused on parents of children younger than 13 years old at two cystic fibrosis center sites (Site 1, n= 83; Site 2, n = 59). Religious and/or spiritual constructs, depression, and marital adjustment were measured by using previously validated questionnaires. Determinants of adherence included parental attitude toward treatment, perceived behavioral norms, motivation, and self-efficacy. Adherence patterns were measured with the Daily Phone Diary, a validated instrument used to collect adherence data. Cluster analysis identified discrete adherence patterns, including parents' completion of more treatments than prescribed. For airway clearance therapy, four adherence groups were identified: median adherence rates of 23%, 52%, 77%, and 120%. These four groups differed significantly for parental depression, sanctification of their child's body, and self-efficacy. Three adherence groups were identified for nebulized medications: median adherence rates of 35%, 82%, and 130%. These three groups differed significantly for sanctification of their child's body and self-efficacy. Our results indicated that parents in each group shared psychosocial and religious and/or spiritual factors that differentiated them. Therefore, conversations about adherence likely should be tailored to baseline adherence patterns. Development of efficacious religious and/or spiritual interventions that promote adherence by caregivers of children with cystic fibrosis may be useful.

This cross-sectional study was carried out to determine the prevalence of overweight and obesity among secondary school children aged 12 to 14 years in the city of Mashhad, Iran and its association with parental body mass index. A total of 1189 secondary school children (579 males and 610 females) aged 12- 14 years old were selected through a stratified multistage random sampling. All adolescents were measured for weight and height. Household socio-demographic information and parental weight and height were self-reported by parents. Adolescents were classified as overweight or obese based on BMI-for age Z-score. Multivariable logistic Regression (MLR) determined the relationship between parental BMI and adolescent overweight and obesity. The overall prevalence of overweight and obesity among secondary school children in Mashhad was 17.2% and 11.9%, respectively. A higher proportion of male (30.7%) than female (27.4%) children were overweight or obese. BMI of the children was significantly related to parental BMI (p<0.001), gender (p= 0.02), birth order (p<0.01), parents' education level (p<0.001), father's employment status (p<0.001), and family income (p<0.001). MLR showed that the father's BMI was significantly associated with male BMI (OR: 2.02) and female BMI (OR: 1.59), whereas the mother's BMI was significantly associated with female BMI only (OR: 0.514). The high prevalence of overweight/obesity among the research population compared with previous studies in Iran could be related to the changing lifestyle of the population. The strong relationship with parental BMI was probably related to a combination of genetic and lifestyle factors. Strategies to address childhood obesity should consider the interaction of these factors.

Child and adolescent trauma exposure is prevalent, with trauma exposure-related symptoms, including posttraumatic stress, depressive, and anxiety symptoms often causing substantial impairment. This article updates the evidence base on psychosocial treatments for child and adolescent trauma exposure completed for this journal by Silverman et al. (2008). For this review, we focus on 37 studies conducted during the seven years since the last review. Treatments are grouped by overall treatment family (e.g., cognitive behavioral therapy), treatment modality (e.g., individual vs. group), and treatment participants (e.g., child only vs. child and parent). All studies were evaluated for methodological rigor according to Journal of Clinical Child & Adolescent Psychology evidence-based treatment evaluation criteria (Southam-Gerow & Prinstein, 2014), with cumulative designations for level of support for each treatment family. Individual CBT with parent involvement, individual CBT, and group CBT were deemed well-established; group CBT with parent involvement and eye movement desensitization and reprocessing (EMDR) were deemed probably efficacious; individual integrated therapy for complex trauma and group mind–body skills were deemed possibly efficacious; individual client-centered play therapy, individual mind–body skills, and individual psychoanalysis were deemed experimental; and group creative expressive + CBT was deemed questionable efficacy. Advances in the evidence base, with comparisons to the state of the science at the time of the Silverman et al. (2008) review, are discussed. Finally, we present dissemination and implementation challenges and areas for future research. PMID:27759442

This study investigated 48 2.5-year-olds' ability to map from their own body to a two-dimensional self-representation and also examined relations between parents' talk about body representations and their children's understanding of self-symbols. Children participated in two dual-representation tasks in which they were asked to match body parts between a symbol and its referent. In one task, they used a self-symbol and in the other they used a symbol for a doll. Participants were also read a book about body parts by a parent. As a group, children found the self-symbol task more difficult than the doll-task; however, those whose parents explicitly pointed out the relation between their children's bodies and the symbols in the book performed better on the self-symbol task. The findings demonstrate that 2-year-old children have difficulty comprehending a self-symbol, even when it is two-dimensional and approximately the same size as them, and suggest that parents' talk about self-symbols may facilitate their understanding. © 2014 The British Psychological Society.

The 2014 KCG Meteor Outburst: Clues to a Parent Body

NASA Technical Reports Server (NTRS)

Moorhead, Althea V.; Brown, Peter G.; Spurny, Pavel; Cooke, William J.

2015-01-01

The Kappa Cygnid (KCG) meteor shower exhibited unusually high activity in 2014, producing ten times the typical number of meteors. The shower was detected in both radar and optical systems and meteoroids associated with the outburst spanned at least five decades in mass. In total, the Canadian Meteor Orbit Radar, European Network, and NASA All Sky and Southern Ontario Meteor Network produced thousands of KCG meteor trajectories. Using these data, we have undertaken a new and improved characterization of the dynamics of this little-studied, variable meteor shower. The Cygnids have a di use radiant and a significant spread in orbital characteristics, with multiple resonances appearing to play a role in the shower dynamics. We conducted a new search for parent bodies and found that several known asteroids are orbitally similar to the KCGs. N-body simulations show that the two best parent body candidates readily transfer meteoroids to the Earth in recent centuries, but neither produces an exact match to the KCG radiant, velocity, and solar longitude. We nevertheless identify asteroid 2001 MG1 as a promising parent body candidate.

Cosmic-ray exposure ages of the ordinary chondrites and their significance for parent body stratigraphy

Crabb, J.; Schultz, L.

1981-01-01

Improved exposure ages are derived for 201 H, 203 L, and 38 LL chondrites in an effort to understand the characteristics of the chondrite parent body. The Ne-21 exposure ages were calculated from literature values taking into account shielding differences, a trapped component and radiogenic He. The exposure age distributions show clear peaks at 4.5 and 20 million years for the H chondrites, while the Ls and LLs appear more as a continuous series of intermediate peaks which may be modeled by at least six peaks between 1 and 35 million years in the case of L chondrites. The observations that every petrological type occurs in each large peak and contain solar wind gases suggest that the parent bodies have been fragmented and reassembled into a megabreccia. The H meteorites are proposed to represent the surface layer of a body with a substantial, active regolith as indicated by the relatively high abundances of solar gases. The L chondrites, on the other hand, are attributed to a parent body that was fragmented by collision about 500 million years ago.

Many young adolescents are dissatisfied with their body due to a discrepancy between their ideal and actual body size, which can lead to weight cycling, eating disorders, depression, and obesity. The current study examined the associations of parental and peer factors with fifth-graders’ body image discrepancy, physical self-worth as a mediator between parental and peer factors and body image discrepancy, and how these associations vary by child’s sex. Body image discrepancy was defined as the difference between young adolescents’ self-perceived body size and the size they believe a person their age should be. Data for this study came from Healthy Passages, which surveyed 5,147 fifth graders (51 % females; 34 % African American, 35 % Latino, 24 % White, and 6 % other) and their primary caregivers from the United States. Path analyses were conducted separately for boys and girls. The findings for boys suggest father nurturance and getting along with peers are related negatively to body image discrepancy; however, for girls, fear of negative evaluation by peers is related positively to body image discrepancy. For both boys and girls, getting along with peers and fear of negative evaluation by peers are related directly to physical self-worth. In addition, mother nurturance is related positively to physical self-worth for girls, and father nurturance is related positively to physical self-worth for boys. In turn, physical self-worth, for both boys and girls, is related negatively to body image discrepancy. The findings highlight the potential of parental and peer factors to reduce fifth graders’ body image discrepancy. PMID:23334988

The role of culture in the context of school-based BMI screening.

The high prevalence of overweight and obesity is a significant public health concern in the United States. Minority populations are disproportionately affected, and the impact of obesity on minority children is especially alarming. In this article we discuss school-based BMI reporting, which is intended to increase parental awareness of their children's weight status. This information could potentially lead parents of overweight and obese children to carefully examine and possibly change their children's diet and activity patterns. However, any program related to child weight status must consider culturally defined aspects of body size and shape. In other words, the cultural context in which information on child BMI is presented to and received by parents must be considered. In this article we review parental perceptions of child weight. Multiple studies have shown that parents of overweight or obese children often fail to correctly perceive their children as overweight. Possible reasons for, and implications of, this misperception of child weight status among minority parents are then explored within a cultural framework. The PEN-3 model is used to examine influences on health behaviors and could help inform the development of a culturally sensitive BMI-notification program for minority parents. Reporting materials congruent with the social and cultural values and practices of the target audience are likely to maximize program effectiveness. A culturally based BMI-notification program should be conceptualized as a small step in a comprehensive plan to reduce childhood obesity and improve the current and future health of minority children.

Chondrite parent bodies are among the first large bodies to have formed in the early Solar System, and have since remained almost chemically unchanged having not grown large enough or quickly enough to undergo differentiation. Their major nonvolatile elements bear a close resemblance to the solar photosphere. Previous work has concluded that CM chondrites fall into at least four distinct space exposure age groups (0.1 Ma, 0.2 Ma, 0.6 Ma and >2.0 Ma), but the meaning of these groupings is unclear. It is possible that these meteorites came from different parent bodies which broke up at different times, or instead came from the same parent body which underwent multiple break-up events, or a combination of these scenarios.

The goal of this study was to determine which cognitive behavioral therapy (CBT-HA) treatment components pediatric headache patient stakeholders would report to be most helpful and essential to reducing headache frequency and related disability to develop a streamlined, less burdensome treatment package that would be more accessible to patients and families. Pediatric migraine is a prevalent and disabling condition. CBT-HA has been shown to reduce headache frequency and related disability, but may not be readily available or accepted by many migraine sufferers due to treatment burden entailed. Research is needed to determine systematic ways of reducing barriers to CBT-HA. Qualitative interviews were conducted with 10 patients and 9 of their parents who had undergone CBT-HA. Interviews were analyzed using an inductive thematic analysis approach based upon modified grounded theory. Patients were 13-17.5 years of age (M = 15.4, SD = 1.63) and had undergone CBT-HA ∼1-2 years prior to participating in the study. Overall, patients and their parents reported that CBT-HA was helpful in reducing headache frequency and related disability. Although patients provided mixed reports on the effectiveness of different CBT-HA skills, the majority of patients indicated that the mind and body relaxation skills of CBT-HA (deep breathing, progressive muscle relaxation, and activity pacing in particular) were the most helpful and most frequently used skills. Patients and parents also generally reported that treatment was easy to learn, and noted at least some aspect of treatment was enjoyable. Results from these qualitative interviews indicate that mind and body CBT-HA relaxation skills emerged as popular and effective based on patient and parent report. Future research examining the effectiveness of streamlined pediatric migraine nonpharmacological interventions should include these patient-preferred skills. © 2018 American Headache Society.

In this examination of the association between parenting style and child weight, the neglected concept of 'psychological control' has been added to the generally accepted parenting dimensions 'support' and 'behavioural control'. Also explored is whether the potential association between parenting and child weight is moderated by socio-demographic variables (child's age/ethnicity, and parent's education level). A cross-sectional study was performed among 1,665 parent-child dyads. The children's mean age was 8 years. Their height and weight were measured to calculate their body mass index (BMI). Parents completed a questionnaire to measure the three parenting dimensions. Based on these dimensions, five parenting styles were defined: the authoritative, permissive, authoritarian, neglecting and rejecting parenting style. Child BMI z-scores were regressed on parenting style, adjusting for parental BMI, child ethnicity, and parent's education level. Rejecting parenting, characterized by high psychological control, low support and low behavioural control, is the only parenting style significantly related to child BMI z-scores (β = 0.074, p < 0.001). The positive association was not moderated by socio-demographic variables. By adding the dimension of psychological control to the concept of parenting, this study has further elucidated the mechanisms whereby parenting may affect child weight. Demonstrating that 'rejecting parenting' is associated with a higher child weight, emphasizes the need for longitudinal studies in which parenting style is measured three-dimensionally. Potential mediating effects of parental feeding style and children's eating style, as well as age moderation, should be included in these studies.

Cells release different types of extracellular vesicles (EVs). These EVs contain biomolecules, including proteins and nucleic acids, from their parent cells, which can be useful for diagnostic applications. The aim of this study was to develop a convenient procedure to collect circulating EVs with detectable mRNA or other biomolecules. Magnetic beads coated with annexin A5 (ANX-beads), which bound to phosphatidylserine moieties on the surfaces of most EVs, were tested for their ability to capture induced apoptotic bodies in vitro and other phosphatidylserine-presenting vesicles in body fluids. Our results show that up to 60% of induced apoptotic bodies could be captured by the ANX-beads. The vesicles captured from cultured media or plasma contained amplifiable RNA. Suitable blood samples for EV collection included EDTA-plasma and serum but not heparin-plasma. In addition, EVs in plasma were labile to freeze-and-thaw cycles. In rodents xenografted with human cancer cells, tumor-derived mRNA could be detected in EVs captured from serum samples. Active proteins could be detected in EVs captured from ascites but not from plasma. In conclusion, we have developed a magnetic bead-based procedure for the collection of EVs from body fluids and proved that captured EVs contain biomolecules from their parent cells, and therefore have great potential for disease diagnosis.

Children's living arrangements following separation and divorce: insights from empirical and clinical research.

PubMed

Kelly, Joan B

2007-03-01

When parents separate, children typically enter into new living arrangements with each parent in a pattern determined most often by one or both parents or, failing private agreement, as a result of recommendations and decisions by lawyers, therapists, custody evaluators, or family courts. Most of these decisions have been based on cultural traditions and beliefs regarding postseparation parenting plans, visitation guidelines adopted within jurisdictions, unsubstantiated theory, and strongly held personal values and professional opinions, and have resulted since the 1960s in children spending most of their time with one residential parent and limited time with nonresident, or "visiting", parents. A large body of social science and child development research generated over the past three decades has identified factors associated with risk and resiliency of children after divorce. Such research remains largely unknown and untapped by parents and professionals making these crucial decisions about children's living arrangements. This article highlights empirical and clinical research that is relevant to the shape of children's living arrangements after separation, focusing first on what is known about living arrangements following divorce, what factors influence living arrangements for separated and divorced children, children's views about their living arrangements, and living arrangements associated with children's adjustment following divorce. Based on this research, it is argued that traditional visiting patterns and guidelines are, for the majority of children, outdated, unnecessarily rigid, and restrictive, and fail in both the short and long term to address their best interests. Research-based parenting plan models offering multiple options for living arrangements following separation and divorce more appropriately serve children's diverse developmental and psychological needs.

Parents' education and child body weight in France: The trajectory of the gradient in the early years.

Apouey, Bénédicte H; Geoffard, Pierre-Yves

2016-03-01

This paper explores the relationship between parental education and offspring body weight in France. Using two large datasets spanning the 1991-2010 period, we examine the existence of inequalities in maternal and paternal education and reported child body weight measures, as well as their evolution across childhood. Our empirical specification is flexible and allows this evolution to be non-monotonic. Significant inequalities are observed for both parents' education--maternal (respectively paternal) high education is associated with a 7.20 (resp. 7.10) percentage points decrease in the probability that the child is reported to be overweight or obese, on average for children of all ages. The gradient with respect to parents' education follows an inverted U-shape across childhood, meaning that the association between parental education and child body weight widens from birth to age 8, and narrows afterward. Specifically, maternal high education is correlated with a 5.30 percentage points decrease in the probability that the child is reported to be overweight or obese at age 2, but a 9.62 percentage points decrease at age 8, and a 1.25 percentage point decrease at age 17. The figures for paternal high education are respectively 5.87, 9.11, and 4.52. This pattern seems robust, since it is found in the two datasets, when alternative variables for parental education and reported child body weight are employed, and when controls for potential confounding factors are included. The findings for the trajectory of the income gradient corroborate those of the education gradient. The results may be explained by an equalization in actual body weight across socioeconomic groups during youth, or by changes in reporting styles of height and weight. Copyright © 2015 Elsevier B.V.

To report a correlational study of the relation of body mass index to children's perceptions of physical appearance and global self-worth and depression, as mediated by their perceptions of parental teasing. The relation between depression and self-perception in children with obesity has been reported. Recently, parental factors were found to be related to childhood obesity. Little is known about the effects of perceived parental teasing on depression and self-perception in children. A descriptive correlational research design was used. Data were collected from 455 children in the fifth and sixth grades in four provinces of South Korea using self-report questionnaires for measuring self-perception of physical appearance and global self-worth, depression and perceived parental teasing between October-December in 2009. The children's weight and height information from school health records was used. Multiple regression analysis and the Sobel test were used to identify the mediating effect of perceived parental teasing. Among the children, 20% were overweight or obese. Although children with obesity did not differ in the level of depression from their normal weight counterparts, they demonstrated lower perceived physical appearance and higher perceived parental teasing. The mediating effects of perceived parental teasing were found for the relations between body mass index and self-perception of physical appearance and global self-worth, and body mass index and depression, respectively. Obese children at risk of parental teasing should be identified to prevent their psychological problems. A well-designed intervention study is necessary to examine the effects of psycho-emotional interventions for obese children. © 2012 Blackwell Publishing Ltd.

There is mounting evidence that maternal executive function (EF) plays a critical role in parenting behavior. However, the majority of the research on this topic has been conducted in low-risk samples. The purpose of the present study was to investigate whether individual differences in maternal EF are associated with parenting behavior in the high-risk, high adversity context of family homelessness. The study included 94 mothers and their children, ages 4 to 6 years, living in emergency homeless shelters. Mothers completed a battery of "hot" and "cool" EF tasks as well as a self-report questionnaire of perceived stress. Parenting measures were based on observed parent-child interactions that were later coded for harsh and positive parenting practices. Results indicated that hot EF in mothers was related to positive parenting. The relation between maternal planning ability, assessed by a cool EF task, and harsh parenting was also significant, but only for mothers reporting higher levels of stress. These findings add to a growing body of research suggesting that the influence of EF and other forms of cognitive control on parenting need to be interpreted within the context of environmental stress and adversity.

An uncontrolled study was conducted to evaluate the effects of a group-based program on weight control, metabolic profiles, and obesity-related complications in obese youth. The program consisted of an initial in-patient session and five group sessions, one, two, three, six, and nine months into the study, providing participants and their parents with information about the consequences of obesity and lifestyle modifications. The severity of obesity and obesity-related complications were evaluated at baseline and 12 months after the intervention. The participants' and their parents' perceptions of the program were assessed. Of the obese youth recruited (n=126), 115 completed the study. Their percentage weight for height and percentage body fat decreased significantly (both p<0.001), and their insulin resistance, lipid profiles, and transaminases levels improved (all p<0.01). The prevalence of prediabetes, dyslipidemia, and elevated transaminases decreased significantly (all p<0.05). The participants and their parents perceived the program as valuable. A group-based program is effective in managing childhood obesity, improving metabolic profiles, and alleviating certain obesity-related complications. A group-based program that provides education and raises the awareness of obese children and their parents about the consequences of obesity is an effective model for treating childhood obesity.

A working timeline for the history of ordinary chondrites includes chondrule formation as early as 0-2 Ma after our Solar System's earliest forming solids (CAIs), followed by rapid accretion into undifferentiated planetesimals that were heated internally by 26Al decay and cooled over a period of tens of millions of years. There remains conflict, however, between metallographic cooling rate (Ni-metal) and radioisotopic thermochronometric data over the sizes and lifetimes of the chondrite parent bodies, as well as the timing of impact related disruptions. The importance of establishing the timing of parent body disruption is heightened by the use of meteorites as recorders of asteroid belt wide disruption events and their use to interpret Solar System dynamical models. Here we attempt to resolve these records by contributing new 207Pb-206Pb data obtained on phosphates isolated from nine previously unstudied ordinary chondrites. These new results, along with previously published Pb-phosphate, Ni-metal and thermometry data, are interpreted with a series of numerical models designed to simulate the thermal evolution for a chondrite parent body that either remains intact or is disrupted by impact prior to forming smaller unsorted "rubble piles". Our thermal model and previously published thermometry data limit accretion time to 2.05-2.25 Ma after CAIs. Measured Pb-phosphate data place minimum estimates on parent body diameters of ∼260-280 km for both the L and H chondrite parent bodies. They also consistently show that petrologic Type 6 (highest thermal metamorphism) chondrites from both the H and L bodies have younger ages and, therefore, cooled more slowly than Type 5 (lesser metamorphism) chondrites. This is interpreted as evidence for Type 5 chondrite origination from shallower depths than Type 6 chondrites within initially concentrically zoned bodies. This contrasts metallographic cooling rate data that are inconsistent with such a simple onion shell scenario. One model that can reconcile these two data sets takes into account subtle differences in temperature to which each system responds. This working model requires that disruption occur early enough such that the Ni-metal system can record the cooling rate associated with a rubble pile (<70 Ma), yet late enough that the Pb-phosphate system can record an onion shell structure (>30 Ma). For this 30-70 Ma timeline, reaccretion into smaller rubble piles will ensure that the originally deeply buried and hot Type 6 samples will always cool faster as a result of disruption, yielding nearly uniform ages that record the time of parent body disruption. This is consistent with the available Pb-phosphate data, where all but one Type 6 chondrite (H, n = 3; L, n = 4) yields a cooling age within a narrow 4505 ± 5 Ma timeframe. These data collectively imply that both the H and L chondrite parent bodies were catastrophically disrupted at ∼60 Ma. In addition, combined Ni-metal and Pb-phosphate models confirm that a subset of Type 4 chondrites record early rapid cooling likely associated with erosional impacting of the H and L parent bodies on ∼5 Ma timescales.

The main aim of this study was to examine weight associations between parents and offspring at two time points: 1995-97 and 2006-08, taking into account body mass index (BMI) and waist circumference. The study included 8425 parent-offspring trios who participated in the population based Health Study of Nord Trøndelag (the HUNT Study), Norway, at either the HUNT2 (1995-97) or the HUNT3 (2006-08) survey. We used linear mixed effects models with siblings clustered within mothers to analyze the associations between 1) parental grouped BMI and offspring BMI z-scores and 2) parental grouped waist circumference and offspring waist circumference z-scores. Adolescent and adult overweight and obesity were higher in 2006-08 than in 1995-97, with the greatest increase observed in waist circumference. Both mother's and father's BMI and waist circumference were strongly associated with corresponding measures in offspring. Compared with both parents being normal weight (BMI <25 kg/m2), having two overweight or obese parents (BMI ≥25 kg/m2) was associated with a higher offspring BMI z-score of 0.76 (95% CI; 0.65, 0.87) and 0.64 (95% CI; 0.48, 0.80) in daughters, and 0.76 (95% CI; 0.65, 0.87) and 0.69 (95% CI; 0.53, 0.80) in sons, in 1995-97 and 2006-08 respectively. Offspring with one parent being overweight/obese had BMI z-scores of approximately half of offspring with two parents categorized as overweight/obese. The results of the waist circumference based analyses did not differ substantially from the BMI based analyses. Parental overweight was strongly positively associated with offspring weight both in 1995-97 and 2006-08 where both parents being overweight/obese gave the largest effect. This seemingly stable association, strongly address the importance of public health initiatives towards preventing obesity in parents of both sexes to decrease further obesity expansion in offspring.

Enstatite chondrites and enstatite achondrites (aubrites) were not derived from the same parent body

Brett, Robin; Keil, Klaus

1986-01-01

Enstatite achondrites (aubrites) were not derived from known enstatite chondrites by melting and fractionation on one and the same parent body, for these and other reasons: (1) There is no satisfactory mechanism for fractionating metal plus troilite in enstatite chondrites to form these phases in different proportions and with different Ti contents in aubrites. (2) Many enstatite chondrites and aubrites are regolith or fragmental breccias, but clasts of one within the other have not been found. (3) Cosmic ray exposure ages of the two groups are difficult to explain if they are from the same parent body, but are easy to explain if they are from different parent bodies. Siderophile element abundances in metal from the Mt. Egerton meteorite, which consists of enstatite and metallic Fe, Ni, preclude it from being a complementary differentiate of the aubrites. Rather, it appears that Mt. Egerton was formed from the same source material as enstatite chondrites, but the components were mixed in different proportions.

Mindful parenting training is an application of mindfulness-based interventions that allows parents to perceive their children with unbiased and open attention without prejudgment and become more attentive and less reactive in their parenting. This study examined the effectiveness of mindful parenting training in a clinical setting on child and parental psychopathology and of mindfulness as a predictor of these outcomes. Seventy parents of 70 children (mean age = 8.7) who were referred to a mental health care clinic because of their children's psychopathology participated in an 8-week mindful parenting training. Parents completed questionnaires at pre-test, post-test and 8-week follow-up. A significant decrease was found in children's and parents' psychopathology and a significant increase in mindful parenting and in general mindful awareness. Improvement in general mindful awareness, but not mindful parenting, was found to predict a reduction in parental psychopathology, whereas improvement in mindful parenting, but not general mindful awareness, predicted the reduction of child psychopathology. This study adds to the emerging body of evidence indicating that mindful parenting training is effective for parents themselves and, indirectly, for their children suffering from psychopathology. As parents' increased mindful parenting, but not increased general mindfulness, is found to predict child psychopathology, mindful parenting training rather than general mindfulness training appears to be the training of choice. However, RCTs comparing mindful parenting to general mindfulness training and to parent management training are needed in order to shed more light on the effects of mindful parenting and mechanisms of change.

Near-infrared reflectance spectra-applications to problems in asteroid-meteorite relationships

Near-infrared spectral reflectance data were collected at the Infrared Telescope Facility (IRTF) at Mauna Kea Observatories in 1985 and 1986 for the purpose of searching the region near the 3:1 Kirkwood gap for asteroids with the spectral signatures of ordinary chondrite parent bodies. Twelve reflectance spectra are observed. The presence of ordinary chondrite parent bodies among this specific set of observed asteroids is not obvious, though the sample is biased towards the larger asteroids in the region due to limitations imposed by detector sensitivity. The data set, which was acquired with the same instrumentation used for the 52-color asteroid survey (Bell et al., 1987), also presents some additional findings. The range of spectral characteristics that exist among asteroids of the same taxonomic type is noted. Conclusions based on the findings are discussed.

Individuals with fragile X syndrome (FXS), especially those co-diagnosed with autism spectrum disorder (ASD), face many sensory processing challenges. However, sensory processing measures informed by neurophysiology are lacking. This paper describes the development and psychometric properties of a parent/caregiver report, the Brain-Body Center Sensory Scales (BBCSS), based on Polyvagal Theory. Parents/guardians reported on 333 individuals with FXS, 41% with ASD features. Factor structure using a split-sample exploratory-confirmatory design conformed to neurophysiological predictions. Internal consistency, test-retest, and inter-rater reliability were good to excellent. BBCSS subscales converged with the Sensory Profile and Sensory Experiences Questionnaire. However, data also suggest that BBCSS subscales reflect unique features related to sensory processing. Individuals with FXS and ASD features displayed more sensory challenges on most subscales.

Water and the thermal evolution of carbonaceous chondrite parent bodies

NASA Technical Reports Server (NTRS)

Grimm, Robert E.; Mcsween, Harry Y., Jr.

1989-01-01

Two hypotheses are proposed for the aqueous alteration of carbonaceous chondrites within their parent bodies, in which respectively the alteration occurs (1) throughout the parent body interior, or (2) in a postaccretional surface regolith; both models assume an initially homogeneous mixture of ice and rock that is heated through the decay of Al-26. Water is seen to exert a powerful influence on chondrite evolution through its role of thermal buffer, permitting substitution of a low temperature aqueous alteration for high temperature recrystallization. It is quantitatively demonstrated that liquid water may be introduced by either hydrothermal circulation, vapor diffusion from below, or venting due to fracture.

Are colorful males of great tits Parus major better parents? Parental investment is a matter of quality

NASA Astrophysics Data System (ADS)

Pagani-Núñez, Emilio; Senar, Juan Carlos

2014-02-01

Given the known influence of parental investment on breeding success of great tits Parus major, females should be expected to use male parental quality as an essential criterion in mate choice. Since parental quality cannot usually be observed directly at the time of pairing, it has been suggested that females rely on male ornaments as indicative of their ability to provide parental care. This hypothesis, called the good parent hypothesis, has been tested repeatedly assessing only parental effort as the number of feedings made by parents. However, in evaluating parental investment, the focus should also be on the quality of prey captured rather than only on its quantity. We analyzed feeding rates and the provisioning of different prey in relation to both male yellow carotenoid-based breast coloration and the size of the black melanin-based stripe in a Mediterranean great tit population. We predicted that more carotenoid ornamented individuals would feed nestlings with a diet consisting of a higher proportion of caterpillars. However, and contrary to predictions, we found that males with higher values of hue in the yellow breast feathers, fed their offspring with a lower proportion of caterpillars and a higher proportion of spiders. In addition, nestlings that received a higher proportion of spiders showed an improved body condition after controlling for tarsus length and other variables. Male feeding rates correlated positively with brood size and tended to correlate negatively with date, although we did not find any effect of male coloration. Our data therefore support the good parent hypothesis, insofar as parental investment is also a matter of quality, and that, at least in the Mediterranean area, caterpillars are not the only key food source.

Compositional Homogeneity of CM Parent Bodies

CM chondrites are the most common type of hydrated meteorites, making up ˜1.5% of all falls. Whereas most CM chondrites experienced only low-temperature (˜0°C-120°C) aqueous alteration, the existence of a small fraction of CM chondrites that suffered both hydration and heating complicates our understanding of the early thermal evolution of the CM parent body(ies). Here, we provide new constraints on the collisional and thermal history of CM-like bodies from a comparison between newly acquired spectral measurements of main-belt Ch/Cgh-type asteroids (70 objects) and existing laboratory spectral measurements of CM chondrites. It first appears that the spectral variation observed among CM-like bodies is essentially due to variations in the average regolith grain size. Second, the spectral properties of the vast majority (unheated) of CM chondrites resemble both the surfaces and the interiors of CM-like bodies, implying a “low” temperature (<300°C) thermal evolution of the CM parent body(ies). It follows that an impact origin is the likely explanation for the existence of heated CM chondrites. Finally, similarly to S-type asteroids and (2) Pallas, the surfaces of large (D > 100 km)—supposedly primordial—Ch/Cgh-type main-belt asteroids likely expose the interiors of the primordial CM parent bodies, a possible consequence of impacts by small asteroids (D < 10 km) in the early solar system.

Redistribution of Sr and rare earth elements in the matrices of CV3 carbonaceous chondrites during aqueous alteration in their parent body

We measured the abundances of Sr and rare earth elements (REEs) in the matrices of five CV3 carbonaceous chondrites: Meteorite Hills (MET) 00430, MET 01070, La Paz ice field (LAP) 02206, Asuka (A) 881317 and Roberts Massif (RBT) 04143. In the MET 00430 and MET 01074 matrices, the Sr/CI and light REE (LREE, La-Nd)/CI ratios positively correlate with the amounts of Ca-rich secondary minerals, which formed during aqueous alteration in the CV3 chondrite parent body. In contrast, in the LAP 02206 and RBT 04143 matrices, although the Sr/CI ratios correlate with the amounts of Ca-rich secondary minerals, the LREE/CI ratios vary independently from the amounts of any secondary minerals. This suggests that the LREE/CI ratios in these matrices were produced prior to the parent body alteration, probably in the solar nebula. The LREE/CI ratios of the LAP 02206 and RBT 04143 matrices reveal the mixing process of matrix minerals prior to the accretion of the CV3 chondrite parent body. The mixing degrees of matrix minerals might be different between these two matrices. Because solid materials would be mixed over time according to the radial diffusion model of a turbulent disk, the matrix minerals consisting of LAP 02206 and RBT 04143 matrices might be incorporated into their parent body with different timing.

In order to mitigate childhood obesity, evidence on what influences children's health behaviours is needed to inform new health promotion strategies. The present study investigated the association between parental practices and their child's diet and body weight status. Grade 5 students and their parents completed health surveys. Parents were asked how much they 'encourage their child to eat healthy foods' and how much they 'personally care about healthy eating'. Children's diet quality and vegetable and fruit intake were assessed using an FFQ. Children's heights and weights were measured to determine body weight status. Mixed-effects regression models were used to determine the influence of parental responses on the outcomes of interest. Elementary schools across the province of Alberta, Canada. Grade 5 students (aged 10 and 11 years; n 8388) and their parent(s). Most parents reported caring about healthy eating and encouraging their child to eat healthy foods at least quite a lot. Children whose parents who cared or encouraged 'very much' compared with 'quite a lot' were more likely have better diet quality and were less likely to be overweight. Children whose parents both cared and encouraged 'very much' compared with 'quite a lot' scored an average of 2·06 points higher on the diet quality index (β=2·06; 95 % CI 1·45, 2·66). Health promotion strategies that aim for a high level of parental interest and encouragement of their children to eat healthy foods may improve diet quality and prevent overweight among children.

The increasing prevalence of overweight and obesity among children has become a major public health problem in Malaysia. Parents play an important role in child feeding especially among younger children. A study was conducted to evaluate the beliefs, attitudes and practices in child feeding among parents of normal weight, as well as overweight and obese primary school children in Kelantan using the Child Feeding Questionnaire (CFQ). This cross-sectional study was carried out on 175 Malay children from three schools in Kota Bharu district in Kelantan. This study showed that 13.1% of the children were overweight and obese. Scores for perceived parent weight (p < 0.05) and perceived child weight (p < 0.001) were significantly higher among parents of overweight and obese children compared to parents of children with normal body weight. However, the score for pressure to eat among parents of overweight and obese children was significantly lower (p < 0.05) than parents of normal weight children. The perceived child weight (r = 0.468, p < 0.01), perceived parental weight (r = 0.190, p < 0.05) and food restriction (r = 0.179, p < 0.05) factors were found to be positively correlated with children's body mass index (BMI), whereas pressure to eat factor (r = -0.355, p < 0.01) was negatively correlated with children's body mass index (BMI). The findings showed that parental feeding practices were linked to children's weight status and childhood obesity. Therefore parents should be given education and guidance on appropriate child feeding practices to maintain their child's nutritional status on a healthy weight range.

Thermal evolution of a partially differentiated H chondrite parent body

It has traditionally been assumed that planetesimals either melted entirely or remained completely undifferentiated as they accreted. The unmelted textures and cooling histories of chondrites have been used to argue that these meteorites originated from bodies that never differentiated. However, paleomagnetic measurements indicate that some chondrites (e.g., the H chondrite Portales Valley and several CV chondrites) were magnetized by a core dynamo magnetic field, implying that their parent bodies were partially differentiated. It has been unclear, however, whether planetesimal histories consistent with dynamo production can also be consistent with the diversity of chondrite cooling rates and ages. To address this, we modeled the thermal evolution of the H chondrite parent body, considering a variety of accretion histories and parent body radii. We considered partial differentiation using two-stage accretion involving the initial formation and differentiation of a small body, followed by the later addition of low thermal conductivity chondritic material that remains mostly unmelted. We were able to reproduce the measured thermal evolution of multiple H chondrites for a range of parent body parameters, including initial radii from 70-150 km, chondritic layer thicknesses from 50 km to over 100 km, and second stage accretion times of 2.5-3 Myr after solar system formation. Our predicted rates of core cooling and crystallization are consistent with dynamo generation by compositional convection beginning 60-200 Myr after solar system formation and lasting for at least tens of millions of years. This is consistent with magnetic studies of Portales Valley [Bryson et al., this meeting]. In summary, we find that thermal models of partial differentiation are consistent the radiometric ages, magnetization, and cooling rates of a diversity H chondrites.

2014-01-01

Objective: To assess the feasibility and acceptability of family-based group pediatric obesity treatment in a primary care setting, to obtain an estimate of its effectiveness, and to describe participating parents’ experiences of social support for healthy lifestyle changes. Methods: We adapted an evidence-based intervention to a group format and completed six 12- to 16-week groups over 3 years. We assessed program attendance and completion, changes in child and parent body mass index (BMI; calculated as weight in kilograms divided by height in meters squared), and changes in child quality of life in a single-arm before-and-after trial. Qualitative interviews explored social support for implementing healthy lifestyle changes. Results: Thirty-eight parent-child pairs enrolled (28% of the 134 pairs invited). Of those, 24 (63%) completed the program and another 6 (16%) attended at least 4 sessions but did not complete the program. Children who completed the program achieved a mean change in BMI Z-scores (Z-BMI) of −0.1 (0.1) (p < 0.001) and significant improvement in parent-reported child quality of life (mean change = 8.5; p = 0.002). Mean BMI of parents changed by −0.9 (p = 0.003). Parents reported receiving a wide range of social support for healthy lifestyle changes and placed importance on the absence or presence of support. Conclusions: A pilot group program for family-based treatment of pediatric obesity is feasible and acceptable in a primary care setting. Change in child and parent BMI outcomes and child quality of life among completers were promising despite the pilot’s low intensity. Parent experiences with lack of social support suggest possible ways to improve retention and adherence. PMID:24937148

Parents typically do not recognise their child's weight status accurately according to clinical criteria, and thus may not take appropriate action if their child is overweight. We developed a novel visual intervention designed to improve parental perceptions of child weight status according to clinical criteria for children aged 4-5 and 10-11 years. The Map Me intervention comprises age- and sex-specific body image scales of known body mass index and supporting information about the health risks of childhood overweight. This cluster randomised trial will test the effectiveness of the Map Me intervention. Primary schools will be randomised to: paper-based Map Me; web-based Map Me; no information (control). Parents of reception (4-5 years) and year 6 (10-11 years) children attending the schools will be recruited. The study will work with the National Child Measurement Programme which measures the height and weight of these year groups and provides feedback to parents about their child's weight status. Before receiving the feedback, parents will complete a questionnaire which includes assessment of their perception of their child's weight status and knowledge of the health consequences of childhood overweight. The control group will provide pre-intervention data with assessment soon after recruitment; the intervention groups will provide post-intervention data after access to Map Me for one month. The study will subsequently obtain the child height and weight measurements from the National Child Measurement Programme. Families will be followed-up by the study team at 12 months. The primary outcome is any difference in accuracy in parental perception of child weight status between pre-intervention and post-intervention at one month. The secondary outcomes include differences in parent knowledge, intention to change lifestyle behaviours and/or seek advice or support, perceived control, action planning, coping planning, and child weight status at 12 month follow-up. The Map Me tool has potential to make a positive impact on children's health at a population level by introducing it into current intervention programmes to improve accuracy of parental perception of child's weight status. This trial will inform the action of researchers, educators, health professionals and policy makers. Current Controlled Trials ISRCTN91136472. Registered 3 May 2013.

The Asteroid Veritas: An intruder in a family named after it?

NASA Astrophysics Data System (ADS)

Michel, Patrick; Jutzi, Martin; Richardson, Derek C.; Benz, Willy

2011-01-01

The Veritas family is located in the outer main belt and is named after its apparent largest constituent, Asteroid (490) Veritas. The family age has been estimated by two independent studies to be quite young, around 8 Myr. Therefore, current properties of the family may retain signatures of the catastrophic disruption event that formed the family. In this paper, we report on our investigation of the formation of the Veritas family via numerical simulations of catastrophic disruption of a 140-km-diameter parent body, which was considered to be made of either porous or non-porous material, and a projectile impacting at 3 or 5 km/s with an impact angle of 0° or 45°. Not one of these simulations was able to produce satisfactorily the estimated size distribution of real family members. Based on previous studies devoted to either the dynamics or the spectral properties of the Veritas family, which already treated (490) Veritas as a special object that may be disconnected from the family, we simulated the formation of a family consisting of all members except that asteroid. For that case, the parent body was smaller (112 km in diameter), and we found a remarkable match between the simulation outcome, using a porous parent body, and the real family. Both the size distribution and the velocity dispersion of the real reduced family are very well reproduced. On the other hand, the disruption of a non-porous parent body does not reproduce the observed properties very well. This is consistent with the spectral C-type of family members, which suggests that the parent body was porous and shows the importance of modeling the effect of this porosity in the fragmentation process, even if the largest members are produced by gravitational reaccumulation during the subsequent gravitational phase. As a result of our investigations, we conclude that it is very likely that the Asteroid (490) Veritas and probably several other small members do not belong to the family as originally defined, and that the definition of this family should be revised. Further investigations will be performed to better constrain the definitions and properties of other asteroid families of different types, using the appropriate model of fragmentation. The identification of very young families in turn will continue to serve as a tool to check the validity of numerical models.

The aim of the study was to analyse the parental bonding profiles in patients with eating disorders (ED), as well as the relationship among the different styles of parenting and some psychological and psychopathological variables. In addition, the association between the perceived parental bonding and different coping strategies was analysed. Perception of parenting styles was analysed in a sample of 70 ED patients. The Parental Bonding Instrument, Self-Esteem Scale of Rosenberg, Coping Strategies Inventory, State-Trait Anxiety Inventory, Beck Depression Inventory and Eating Disorders Inventory-2 were used. Kruskal-Wallis test (comparisons), Spearman correlation coefficients (association among different variables) and χ(2)-test (parental bonding profiles differences) were applied. The stereotyped style among ED patients is low care-high control during the first 16 years, and the same can be said about current styles of the mothers. Between 8.6% and 12.9% of the patients perceive their parents' styles as neglectful. The neglectful parenting is the style mainly involved in the specific ED symptoms as drive for thinness, body dissatisfaction and bulimia. In order to achieve a better balanced parents' role during the treatment, it would be necessary to improve the role of the mothers as caregivers, decreasing their role mainly based on the overprotection. © 2011 Blackwell Publishing.

Family based-treatments have the most empirical support in the treatment of adolescent anorexia nervosa; yet, a significant percentage of adolescents and their families do not respond to manualized family based treatment (FBT). The aim of this open trial was to conduct a preliminary evaluation of an innovative family-based approach to the treatment of anorexia: Acceptance-based Separated Family Treatment (ASFT). Treatment was grounded in Acceptance and Commitment Therapy (ACT), delivered in a separated format, and included an ACT-informed skills program. Adolescents (ages 12–18) with anorexia or sub-threshold anorexia and their families received 20 treatment sessions over 24 weeks. Outcome indices included eating disorder symptomatology reported by the parent and adolescent, percentage of expected body weight achieved, and changes in psychological acceptance/avoidance. Half of the adolescents (48.0%) met criteria for full remission at the end of treatment, 29.8% met criteria for partial remission, and 21.3% did not improve. Overall, adolescents had a significant reduction in eating disorder symptoms and reached expected body weight. Treatment resulted in changes in psychological acceptance in the expected direction for both parents and adolescents. This open trial provides preliminary evidence for the feasibility, acceptability, and efficacy of ASFT for adolescents with anorexia. Directions for future research are discussed. PMID:25898341

Objective Previous research suggests that parental divorce moderates genetic influences on body dissatisfaction. Specifically, the heritability of body dissatisfaction is higher in children of divorced versus intact families, suggesting possible gene-environment interaction effects. However, prior research is limited to a single, self-report measure of body dissatisfaction. The primary aim of the present study was to examine whether these findings extend to a different dimension of body dissatisfaction, body image perceptions. Method Participants were 1,534 female twins from the Minnesota Twin Family Study, ages 16–20 years. The Body Rating Scale (BRS) was used to assess body image perceptions. Results Although BRS scores were heritable in twins from divorced and intact families, the heritability estimates in the divorced group were not significantly greater than estimates in the intact group. However, there were differences in nonshared environmental effects, where the magnitude of these environmental influences was larger in the divorced as compared to the intact families. Discussion Different dimensions of body dissatisfaction (i.e., negative self-evaluation versus body image perceptions) may interact with environmental risk, such as parental divorce, in discrete ways. Future research should examine this possibility and explore differential gene x environment interactions using diverse measures. PMID:26314278

Objectives: The childhood obesity epidemic is now recognized as one of the most serious public health challenges of the 21st century. Community-based behaviour modification treatment programs involving both children and their families are warranted. The purpose of this study was to explore the experiences of parents whose children participated in the Children's Health and Activity Modification Program (C.H.A.M.P.): a 4-week lifestyle program delivered as a day-camp for obese children at risk for type II diabetes and their families. Parents were required to attend four half-day education sessions during the intervention period. Methods: Seven focus groups were conducted immediately following the 4-week interventions offered in August 2008 and 2009. The perspectives of 38 parents representing 32 children aged 8-14 with obesity (i.e., body mass index > the 95th percentile) were shared. Results: Overall, parents were pleased with the impact of the program and proud of their children's accomplishments (e.g., increased physical activity levels, enhanced self-esteem, weight loss). Several facilitators to success (e.g., social support; a positive environment) and barriers to its maintenance (e.g., time management; unsupportive family members) were identified, and recommendations were made for future programs. Although parents found the half-day sessions valuable, post-programmatic bi-monthly booster session adherence declined over the one-year follow-up period. Conclusion: Delivered as a 4-week day-camp, C.H.A.M.P. represents a unique approach to the treatment of childhood obesity. Future family-based interventions should consider avenues for intensifying the parental program component whilst employing strategies to promote parental adherence in service of enhancing long-term sustainability of health behaviour changes.

Despite the pervasiveness and negative physical and psychosocial implications of weight-based victimization (WBV) in youth, antibullying polices in schools rarely address this issue. Additionally, children's media perpetuates weight stigma, but regulation of stigmatizing media content is nonexistent. In 2011-2013, a diverse national sample of 2185 parents (n=716 in 2011, 755 in 2012, and 714 in 2013) was analyzed to evaluate parental support for four proposed policies across the 3 years. Actions addressed (1) strengthening policies to reduce weight stigma, (2) media portrayals of children with diverse body sizes, (3) media portrayals of such children engaged in healthy behaviors, and (4) antibullying policies in schools. Chi-square tests with Bonferroni's corrections and multiple logistic regression analyses were conducted. Across time, support for policies to address weight stigma remained consistent or increased, primarily in 2012-2013. At least 86% of participants consistently favored implementing antibullying policies in schools. Parents became increasingly supportive of policies regulating television content to positively portray children of diverse body sizes and show such children engaged in health behaviors, as well as establishing weight-related antibullying policies. Specific predictors of support included gender, race, and political affiliation. There is a consistent and high level of parental support for weight stigma-related policies, particularly for antibullying policies. Findings can inform development of policies to rectify health and social disparities faced by overweight and obese youth.

Appropriate levels of parental perception and concern about child weight are important components of successful obesity treatment, but the factors that contribute to these attitudes need clarification. The aim of this study was to identify child and parent characteristics that best predict parental perceptions and concerns about child weight. A cross-sectional design was used to assess characteristics of parents (e.g. age, income, and feeding attitudes) and children (e.g. body composition, ad libitum intake, and reported physical activity). Results are reported for 75, 4–6 year-olds from diverse ethnicities. Perceived child weight and concern were measured with the Child Feeding Questionnaire (CFQ). Multiple linear regression was used to identify the best models for perceived child weight and concern. For perceived child weight, the best model included parent age, children’s laboratory intake of sugar-sweetened beverages (SSB) and palatable buffet items, and two measures of child body composition (ratio of trunk fat-to-total fat and ratio of leg fat-to-total fat). For concern, child android/gynoid fat ratio explained the largest amount of variance, followed by restrictive feeding and SSB intake. Parental perceptions and concerns about child weight are best explained by models that account for children’s eating behavior and body fat distribution. PMID:23207190

A model composition for Mars derived from the oxygen isotopic ratios of martian/SNC meteorites. [Abstract only

Delaney, J. S.

1994-01-01

Oxygen is the most abundant element in most meteorites, yet the ratios of its isotopes are seldom used to constrain the compositional history of achondrites. The two major achondrite groups have O isotope signatures that differ from any plausible chondritic precursors and lie between the ordinary and carbonaceous chondrite domains. If the assumption is made that the present global sampling of chondritic meteorites reflects the variability of O reservoirs at the time of planetessimal/planet aggregation in the early nebula, then the O in these groups must reflect mixing between known chondritic reservoirs. This approach, in combination with constraints based on Fe-Mn-Mg systematics, has been used previously to model the composition of the basaltic achondrite parent body (BAP) and provides a model precursor composition that is generally consistent with previous eucrite parent body (EPB) estimates. The same approach is applied to Mars exploiting the assumption that the SNC and related meteorites sample the martian lithosphere. Model planet and planetesimal compositions can be derived by mixing of known chondritic components using O isotope ratios as the fundamental compositional constraint. The major- and minor-element composition for Mars derived here and that derived previously for the basaltic achondrite parent body are, in many respects, compatible with model compositions generated using completely independent constraints. The role of volatile elements and alkalis in particular remains a major difficulty in applying such models.

The fragile structure of chondritic-porous interplanetary dust particles (CP-IDPs) and their minimal parent-body alteration have led researchers to believe these particles originate in comets rather than asteroids where aqueous and thermal alterations have occurred. The solar elemental abundances and atmospheric entry speed of CP-IDPs also suggest a cometary origin. With the return of the Stardust samples from Jupiter-family comet 81P/Wild 2, this hypothesis can be tested. We have measured the Fe oxidation state of 15 CP-IDPs and 194 Stardust fragments using a synchrotron-based x-ray microprobe. We analyzed {approx}300 ng of Wild 2 material - three orders of magnitude more materialmore » than other analyses comparing Wild 2 and CP-IDPs. The Fe oxidation state of these two samples of material are > 2{sigma} different: the CP-IDPs are more oxidized than the Wild 2 grains. We conclude that comet Wild 2 contains material that formed at a lower oxygen fugacity than the parent-body, or parent bodies, of CP-IDPs. If all Jupiter-family comets are similar, they do not appear to be consistent with the origin of CP-IDPs. However, comets that formed from a different mix of nebular material and are more oxidized than Wild 2 could be the source of CP-IDPs.« less

A growing body of research has been examining neighborhood environment related to children's physical activity and obesity. However, there is still not enough evidence from Latin America. To investigate the association of neighborhood and family perceived environments, use of and distance to public open spaces with leisure-time physical activity (LTPA) and body mass index (BMI) in Argentinean school-aged children. School-based, cross-sectional study with 1777 children (9 to 11years) and their parents, in Cordoba city during 2011. Children were asked about LTPA and family perceived environment. Parents were asked about neighborhood perceived environment, children's use of public open spaces and distance. Weight and height were measured for BMI. We modeled children's LTPA and BMI z-score with structural equation models with latent variables for built, social and safety neighborhood environments. Parents' perceived neighborhood environment was not related with children's LTPA and BMI. Children's perceived autonomy and family environment were positively associated with LTPA. Use of unstructured open spaces and, indirectly, the distance to these, was associated with LTPA among girls. Greater distance to parks reduced their use by children. Policies to increase children's LTPA should include access to better public open spaces, increasing options for activity. A family approach should be incorporated, reinforcing its role for healthy development. Copyright © 2015 Elsevier Inc. All rights reserved.

Living with a mentally ill parent: exploring adolescents' experiences and perspectives.

Trondsen, Marianne V

2012-02-01

Although a considerable body of research has described the implications of parental mental illness, the perspectives of children and adolescents have rarely been addressed. In this article, I explore adolescents' experiences in everyday life, based on an action-oriented study of a Norwegian online self-help group for adolescents (aged 15 to 18) with mentally ill parents. The analysis was conducted through participant observation of the group for 2 years. The adolescents experienced a variety of difficult challenges related to their parent's mental illness: lack of information and openness; unpredictability and instability; fear; loneliness; and loss and sorrow. However, they also discussed strategies for active management of the challenges arising from the family situation. I argue that these adolescents can be understood as vulnerable as well as active participants in managing their everyday lives. I emphasize the importance of including perspectives of children and adolescents in further research so as to improve health care for families with parental mental illness.

To investigate the relationship between a child's weight and a broad range of family and maternal factors. Cross-sectional data from a population-based prospective study, collected between January 2004 and December 2005, for 329 children aged 6-13 years (192 healthy weight, 97 overweight and 40 obese) and their mothers (n=265) recruited from a paediatric hospital endocrinology department and eight randomly selected primary schools in Perth, Western Australia. Height, weight and body mass index (BMI) of children and mothers; demographic information; maternal depression, anxiety, stress and self-esteem; general family functioning; parenting style; and negative life events. In a multilevel model, maternal BMI and family structure (single-parent v two-parent families) were the only significant predictors of child BMI z scores. Childhood obesity is not associated with adverse maternal or family characteristics such as maternal depression, negative life events, poor general family functioning or ineffective parenting style. However, having an overweight mother and a single-parent (single-mother) family increases the likelihood of a child being overweight or obese.

To describe sleep duration and sleep characteristics, and to examine the associations between sleep duration and characteristics and body weight status, diet quality, and physical activity levels among grade 5 children in Nova Scotia. A provincially representative sample of 5,560 grade 5 children and their parents in Nova Scotia was surveyed. Parents were asked to report their child's bedtime and wake-up time, and to indicate how often their child snored or felt sleepy during the day. Dietary intake and physical activity were selfreported by children using the Harvard Youth/Adolescent Food Frequency Questionnaire and the Physical Activity Questionnaire for Children respectively. Body weight status was determined using measured heights and weights. Linear and logistic random effects models with children nested within schools were used to test for associations. Approximately half of the surveyed parents reported that their children were not getting adequate sleep at night. Longer sleep duration was statistically significantly associated with decreased risk for overweight and obesity independent of other sleep characteristics (OR = 0.82, 95% CI: 0.73, 0.91). Longer sleep duration was also associated with better diet quality and higher levels of physical activity. These findings indicate a need for health promotion strategies to encourage adequate sleep and to promote healthy sleep environments among children. Given the links among sleep, body weight status and lifestyle behaviours, these messages should be included in public health interventions aimed at preventing obesity and promoting health among children.

Metamorphism and partial melting of ordinary chondrites: Calculated phase equilibria

Constraining the metamorphic pressures (P) and temperatures (T) recorded by meteorites is key to understanding the size and thermal history of their asteroid parent bodies. New thermodynamic models calibrated to very low P for minerals and melt in terrestrial mantle peridotite permit quantitative investigation of high-T metamorphism in ordinary chondrites using phase equilibria modelling. Isochemical P-T phase diagrams based on the average composition of H, L and LL chondrite falls and contoured for the composition and abundance of olivine, ortho- and clinopyroxene, plagioclase and chromite provide a good match with values measured in so-called equilibrated (petrologic type 4-6) samples. Some compositional variables, in particular Al in orthopyroxene and Na in clinopyroxene, exhibit a strong pressure dependence when considered over a range of several kilobars, providing a means of recognising meteorites derived from the cores of asteroids with radii of several hundred kilometres, if such bodies existed at that time. At the low pressures (<1 kbar) that typify thermal metamorphism, several compositional variables are good thermometers. Although those based on Fe-Mg exchange are likely to have been reset during slow cooling, those based on coupled substitution, in particular Ca and Al in orthopyroxene and Na in clinopyroxene, are less susceptible to retrograde diffusion and are potentially more faithful recorders of peak conditions. The intersection of isopleths of these variables may allow pressures to be quantified, even at low P, permitting constraints on the minimum size of parent asteroid bodies. The phase diagrams predict the onset of partial melting at 1050-1100 °C by incongruent reactions consuming plagioclase, clinopyroxene and orthopyroxene, whose compositions change abruptly as melting proceeds. These predictions match natural observations well and support the view that type 7 chondrites represent a suprasolidus continuation of the established petrologic types at the extremes of thermal metamorphism. The results suggest phase equilibria modelling has potential as a powerful quantitative tool in investigating, for example, progressive oxidation during metamorphism, the degree of melting and melt loss or accumulation required to produce the spectrum of differentiated meteorites, and whether the onion shell or rubble pile model best explains the metamorphic evolution of asteroid parent bodies in the early solar system.

Objective To assess familial links in fat stereotypes and predictors of stereotypes among girls and their parents. Research Methods and Procedures Fat stereotypes were assessed using a questionnaire developed for this study. Participants indicated the extent to which they agreed with nine statements about thin people (e.g., thin people are smart) and the same statements about fat people (e.g., fat people are smart). Predictors of fat stereotypes that were examined include weight status (BMI; girls and parents), education (parents), income (parents), self-investment in physical appearance (parents), maladaptive eating attitudes (girls), and parenting practices and peer interactions focused on body shape and weight loss (girls). Results Girls and parents exhibited fat stereotypes. Fathers who were more educated and had a higher family income were more likely to endorse fat stereotypes, as were mothers and fathers with a high investment in their physical appearance. Although no associations were found between girls’ and parents’ fat stereotypes, girls were more likely to endorse fat stereotypes when interactions with parents and peers focused on body shape and weight loss. Girls were also more likely to endorse fat stereotypes when they reported higher levels of maladaptive eating attitudes. No associations were found between weight status and fat stereotypes. Discussion Although there was no association between girls’ and parents’ fat stereotypes, girls were more likely to express negative attitudes about obesity and obese persons when parenting practices and interactions with peers promoted a lean body type, suggesting that there may be an implicit link between the lean ideal and fat stereotypes.

Identifying early developmental indicators of risk for schizophrenia is important for prediction and possibly illness prevention. Disturbed intermodality has been proposed as one important neurodevelopmental risk for schizophrenia. Early intermodal integration (EII) is the infant’s ability to link motility and perception and to relate perception across modalities. We hypothesized that infants of parents with schizophrenia would have more EII abnormalities than infants of healthy parents and that infants of parents with affective psychosis would be intermediate in severity. The New England Family Study high-risk sample, ascertained from community populations, was utilized. Eight-month-old infants of parents with schizophrenia (n = 58), affective psychoses (n = 128), and healthy controls (n = 174) were prospectively assessed. Diagnoses of parents were determined 30 years later blind to offspring data. EII measures were grouped into 3 domains characterizing different aspects of infant development: (1) one’s own body, (2) objects, and (3) social interactions. Results demonstrated that body- and object-related EII abnormalities were significantly increased for infants of parents with schizophrenia compared with control infants and not significantly increased for infants of parents with affective psychoses. EII abnormalities in relation to social interactions were significantly increased in infants of parents with schizophrenia and affective psychoses. Thus, body- and object-related EII abnormalities were most severe in infants of parents with schizophrenia, supporting the importance of intermodality dysfunction as an early indicator of the vulnerability to schizophrenia. Future research should evaluate how this dysfunction evolves with development and its associations with other psychopathological and neurodevelopmental deficits in youth at risk for psychosis.

Could parental rules play a role in the association between short sleep and obesity in young children?

Short sleep duration is associated with obesity in young children. This study develops the hypothesis that parental rules play a role in this association. Participants were 3-year-old children and their parents, recruited at nursery schools in socioeconomically deprived and non-deprived areas of a North-East England town. Parents were interviewed to assess their use of sleep, television-viewing and dietary rules, and given diaries to document their child's sleep for 4 days/5 nights. Children were measured for height, weight, waist circumference and triceps and subscapular skinfold thicknesses. One-hundred and eight families participated (84 with complete sleep data and 96 with complete body composition data). Parental rules were significantly associated together, were associated with longer night-time sleep and were more prevalent in the non-deprived-area compared with the deprived-area group. Television-viewing and dietary rules were associated with leaner body composition. Parental rules may in part confound the association between night-time sleep duration and obesity in young children, as rules cluster together across behavioural domains and are associated with both sleep duration and body composition. This hypothesis should be tested rigorously in large representative samples.

Do We Already have Samples of CERES H Chondrite Haliites and the CERES-HEBE Link

NASA Technical Reports Server (NTRS)

Fries, Marc D.; Messenger, S.; Steele, A.; Zolensky, M.

2013-01-01

We investigate the hypothesis that halite grains in the brecciated H chondrites Zag and Monahans originate from Ceres. Evidence includes mineralogy of the halites consistent with formation on a large, carbonaceous, aqueously active body close to the H chondrite parent body >4 Ga ago. Evidence also includes orbital simularities between 1 Ceres and the purported H chondrite parent body (HPB) 6 Hebe, possibly facilitating a gentle transfer between the bodies. Halite grains in the Monahans and Zag Hchondrites are exogenous to the H chondrite parent body and were transported to the HPB >4 Ga ago. Examination of minerals and carboanceous materials entrained within the halites shows that the halite parent body (HaPB) is consistent with a carbonaceous body [1]. It is probably a large body due to the variety of entrained carbonaceous materials which probably accreted from multiple sources. The halite grains contain intact, HaPB-origin, ancient fluid inclusions indicating that transfer between the HaPB and the HPB was a gentle process resulting in a ?T of <25 degC. Ejection from the HaPB may have been via cryovolcanic processes similar to those on modern-day Enceladus, which have been interpreted to include halite from spectroscopic observations. The ?Tmax to preserve the brinebearing halite restricts the impact velocity to the HPB at less than ˜350-700 m/s, depending upon the fraction of kinetic energy used heat the sample. [2-6]. Therefore the HaPB and HPB must have shared nearby orbits at the time of the HaPB-HPB transfer. Evidence presented elsewhere indicates asteroid 6 Hebe is a favored candidate for the HPB based on reflectance spectrum similarity with H chondrites and dynamical arguments [7,8]. The modern orbits of Ceres and Hebe are reasonably similar, with aphelion/perihelion of Ceres and Hebe of 2.99/2.55 and 2.91/1.94 AU, respectively. Initial calculations indicate an approximate mean infall velocity of 1.20 to 1.38 km/s. While higher than 350- 700 m/s, the orbits may have been more favorable >4 Ga ago. Additional dynamical factors need to be investigated. A combination of factors suggests Ceres as the HaPB. It is a carbonaceous body with suggestions of past aqueous activity [9], which is consistent with the mineral species found in H chondrite halites. Ceres is also a large body capable of accreting the range of carbonaceous materials noted [5]. It is relatively near to purported HPB Hebe, which is required to preserve halite fluid inclusions. The above evidence defines a hypothesized scenario featuring ejection of halite grains from Ceres onto Hebe. Halite was then entrained in H-chondrite near-surface breccias and ejected from Hebe for transport to Earth.

Late metal-silicate separation on the IAB parent asteroid: Constraints from combined W and Pt isotopes and thermal modelling

NASA Astrophysics Data System (ADS)

Hunt, Alison C.; Cook, David L.; Lichtenberg, Tim; Reger, Philip M.; Ek, Mattias; Golabek, Gregor J.; Schönbächler, Maria

2018-01-01

The short-lived 182Hf-182W decay system is a powerful chronometer for constraining the timing of metal-silicate separation and core formation in planetesimals and planets. Neutron capture effects on W isotopes, however, significantly hamper the application of this tool. In order to correct for neutron capture effects, Pt isotopes have emerged as a reliable in-situ neutron dosimeter. This study applies this method to IAB iron meteorites, in order to constrain the timing of metal segregation on the IAB parent body. The ε182W values obtained for the IAB iron meteorites range from -3.61 ± 0.10 to -2.73 ± 0.09. Correlating εiPt with ε182W data yields a pre-neutron capture ε182W of -2.90 ± 0.06. This corresponds to a metal-silicate separation age of 6.0 ± 0.8 Ma after CAI for the IAB parent body, and is interpreted to represent a body-wide melting event. Later, between 10 and 14 Ma after CAI, an impact led to a catastrophic break-up and subsequent reassembly of the parent body. Thermal models of the interior evolution that are consistent with these estimates suggest that the IAB parent body underwent metal-silicate separation as a result of internal heating by short-lived radionuclides and accreted at around 1.4 ± 0.1 Ma after CAIs with a radius of greater than 60 km.

Search for a Differentiated Asteroid Family

NASA Astrophysics Data System (ADS)

Thomas, Cristina A.; Lim, Lucy F.; Trilling, David E.; Moskovitz, Nicholas

2014-08-01

Dynamical asteroid families resulting from catastrophic disruptions represent the interiors of their former parent bodies. Differentiation of a large initially chondritic parent body is expected to produce an ``onion shell" object with a metal core, a thick olivine-rich mantle, and a thin basaltic crust. However, instead of the mineralogical diversity expected from the disruption of a differentiated parent body, most asteroid families tend to show similar spectra among the members. Moreover, spectra of metal-like materials and olivine-dominated assemblages have not been detected in asteroid families in the Main Belt and the expected mantle material is missing from the meteorite record. The deficit of olivine-rich mantle material in the meteorite record and in asteroid observations is known as the ``Missing Mantle" problem. For years the best explanation for the lack of mantle material has been the ``battered to bits" hypothesis that states that all differentiated parent bodies (aside from Vesta) were disrupted very early in the solar system and the resulting olivine-rich material was collisionally broken down until the object diameters fell below our observational limits. However, in a new, competing, hypothesis, Elkins-Tanton et al. (2013) has suggested that previous work has overestimated the amount of olivine produced by the differentiation of a chondritic parent body. We propose to obtain visible spectra of asteroids within the Massalia, Merxia, and Agnia S-type families to search for compositional variations that are indicators of differentiation and to quantitatively constrain the two competing ``Missing Mantle" hypotheses.

Parenting styles, feeding styles, and their influence on child obesogenic behaviors and body weight. A review.

PubMed

Vollmer, Rachel L; Mobley, Amy R

2013-12-01

With recommendations to include parents as targets for childhood obesity interventions, there is a need to review the relationship of general parenting influences on childhood obesity. Therefore, the aim of this review is to examine the existing literature regarding the influence of parenting style and/or feeding styles on childhood obesogenic behaviors and body weight. Research articles related to parenting style (n=40) and parental feeding style (n=11) were identified and reviewed. An authoritative style appears to be the most protective parenting and feeding style while the indulgent feeding style is consistently associated with negative health outcomes. Overall, results for parenting style studies are inconsistent due to differences in conceptualization and measurement, while the results for feeding styles are much more cohesive. The literature is lacking in the ability to describe the interplay between parenting and feeding styles and child obesity risk. Recommendations for future research and interventions are discussed in regards to feeding style and influences on childhood obesity. Copyright © 2013 Elsevier Ltd. All rights reserved.

It is well known that the prevalence of overweight and obesity is considerably higher among youth from lower socio-economic families, but there is little information about the role of some energy balance-related behaviors in the association between socio-economic status and childhood overweight and obesity. The objective of this paper was to assess the possible mediation role of energy balance-related behaviors in the association between parental education and children's body composition. Data were obtained from the cross sectional study of the "EuropeaN Energy balance Research to prevent excessive weight Gain among Youth" (ENERGY) project. 2121 boys and 2516 girls aged 10 to 12 from Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia and Spain were included in the analyses. Data were obtained via questionnaires assessing obesity related dietary, physical activity and sedentary behaviors and basic anthropometric objectively measured indicators (weight, height, waist circumference). The possible mediating effect of sugared drinks intake, breakfast consumption, active transportation to school, sports participation, TV viewing, computer use and sleep duration in the association between parental education and children's body composition was explored via MacKinnon's product-of-coefficients test in single and multiple mediation models. Two different body composition indicators were included in the models, namely Body Mass Index and waist circumference. The association between parental education and children's body composition was partially mediated by breakfast consumption, sports participation, TV viewing and computer use. Additionally, a suppression effect was found for sugared drinks intake. No mediation effect was found for active transportation and sleep duration. The significant mediators explained a higher proportion of the association between parental education and waist circumference compared to the association between parental education and BMI. Tailored overweight and obesity prevention strategies in low SES preadolescent populations should incorporate specific messages focusing on the importance of encouraging daily breakfast consumption, increasing sports participation and decreasing TV viewing and computer use. However, longitudinal research to support these findings is needed.

Over 30% of youth and adolescents have overweight or obesity, and health care providers are increasingly discussing weight-based health with these patients. Stigmatizing language in provider-patient communication about obesity is well documented and could be particularly detrimental to youth and adolescents. Although some research has examined preferences for weight-based terminology among adults, no studies have addressed these issues in youth populations. This study represents a preliminary and systematic investigation of weight-based language preferences among adolescents with overweight and obesity enrolled in a summer weight loss camp. Participants (N=50) indicated preferences for weight-based language and emotional responses to words that their family members used in reference to their body weight. Weight neutral terminology ('weight', 'body mass index') were most preferred, although some differences in word preferences emerged by the participants' gender. Boys preferred having their weight described as 'overweight' and 'heavy', while girls preferred the word 'curvy'. A large proportion of participants, particularly girls, reported experiencing sadness, shame, and embarrassment if parents used certain words to describe their body weight, which highlights the importance of considering the emotional impact of weight-based terminology. Providers may consider asking youth and adolescents for their preferences when discussing weight-based health.

In this study, acrylamide exposure from selected cereal-based baby food samples was investigated among toddlers aged 1-3 years in Turkey. The study contained three steps. The first step was collecting food consumption data and toddlers' physical properties, such as gender, age and body weight, using a questionnaire given to parents by a trained interviewer between January and March 2012. The second step was determining the acrylamide levels in food samples that were reported on by the parents in the questionnaire, using a gas chromatography-mass spectrometry (GC-MS) method. The last step was combining the determined acrylamide levels in selected food samples with individual food consumption and body weight data using a deterministic approach to estimate the acrylamide exposure levels. The mean acrylamide levels of baby biscuits, breads, baby bread-rusks, crackers, biscuits, breakfast cereals and powdered cereal-based baby foods were 153, 225, 121, 604, 495, 290 and 36 μg/kg, respectively. The minimum, mean and maximum acrylamide exposures were estimated to be 0.06, 1.43 and 6.41 μg/kg BW per day, respectively. The foods that contributed to acrylamide exposure were aligned from high to low as bread, crackers, biscuits, baby biscuits, powdered cereal-based baby foods, baby bread-rusks and breakfast cereals.

This study examined the role of demographic characteristics, psychological factors, and family functioning on attendance in a randomized controlled trial of a family-based pediatric obesity program. Participants included 155 children between the ages of 4 and 7 years (M age = 5.77, 57.4% female, 73.6% black, M body mass index = 25.5) and their primary caregivers who were randomized to the treatment group. Three groups of participants were created based on their patterns of attendance during the program: (1) noncompleters, (2) partial completers, and (3) completers. Results indicated no differences among the attendance groups in child gender, child body mass index, or child psychological functioning. Significant group differences were found with respect to race/ethnicity, parent marital status, and family income, such that noncompleters were more likely to be racial/ethnic minorities, to living in single parent households, and to have lower incomes than partial completers and completers. After controlling for the effects of these sociodemographic risk factors, noncompleters, and partial completers reported more family dysfunction characterized by high levels of disengagement than completers. Adapting existing weight management programs to include a focus on family engagement in the early stages of treatment may help to improve participation in family-based obesity interventions targeting high risk, socioeconomically disadvantaged youth.

Parental Involvement in Middle School: A Meta-Analytic Assessment of the Strategies That Promote Achievement

Early adolescence is often marked by changes in school context, family relationships, and developmental processes. In the context of these changes, academic performance often declines, while at the same time the long-term implications of academic performance increase. In promoting achievement across elementary and secondary school levels, the significant role of families, family-school relations, and parental involvement in education has been highlighted. Although there is a growing body of literature focusing on parental involvement in education during middle school, this research has not been systematically examined to determine which types of involvement have the strongest relation with achievement. The authors conducted a meta-analysis on the existing research on parental involvement in middle school to determine whether and which types of parental involvement are related to achievement. Across 50 studies, parental involvement was positively associated with achievement, with the exception of parental help with homework. Involvement that reflected academic socialization had the strongest positive association with achievement. Based on the known characteristics of the developmental stage and tasks of adolescence, strategies reflecting academic socialization are most consistent with the developmental stage of early adolescence.

Parent body depth-pressure-temperature relationships and the style of the ureilite anatexis

NASA Astrophysics Data System (ADS)

Warren, Paul H.

2012-02-01

New analyses of mafic silicates from 14 ureilite meteorites further constrain a strong correlation (Singletary and Grove 2003) between olivine-core Fo ratio and the temperature of equilibration (TE) recorded by the composition of pigeonite. This correlation may be compared with relationships implied by various postulated combinations of Fo and pressure P in models for ureilite genesis by a putative process of anatectic (depth-linked, P-controlled) smelting. In such models, any combination of Fo and P together fixes the temperature of smelting. Agreement between the observed correlation and these models is poor. The anatectic smelting model also carries implausible implications for the depth range at which ureilites of a given composition (Fo) form. Actual ureilites (and polymict ureilite clasts: Downes et al. 2008) show a distribution strongly skewed toward the low-Fo end of the compositional range, with approximately 58% in the range Fo76-81. In contrast, the P-controlled smelting model implies that the Fo76-81 region is a small fraction of the volume of the parent body: not more than 3.2%, in a model consistent with the Fo-TE observations; and even ignoring the Fo-TE evidence not more than 11% (percentages cited require optimal assumptions concerning the size of the parent body). This region also must occur deep within the body, where no straightforward model would imply a strong bias in the impact-driven sampling process. The ureilites did not derive preponderantly from one atypical “largest offspring” disruption survivor, because cooling history evidence shows that after the disruption (whose efficiency was increased by gas jetting), all of the known ureilites cooled in bodies that were tiny (mass of order 10-9) in comparison with the precursor body. The Ca/Al ratio of the ureilite starting matter cannot be 2.5 times chondritic, as has been suggested, unless the part of the body from which ureilites come is at most 50% of the whole body. Published variants of the anatectic, P-controlled smelting model have the ureilites coming from a region that is >50 vol% of their parent body; and to invoke a larger body would have the drawback of implying that the Fo76-81 spike represents an even smaller fraction of the parent body's interior. The ureilites' moderate depletions in incompatible elements are difficult to reconcile with a fractional fusion model. It is not plausible that melt formed grossly out of equilibrium with the medium-sized ureilite crystals. The alternative to pressure-controlled smelting, i.e., a model of gasless or near-gasless anatexis, has very different implications for the size and evolution of the original parent body. To yield internal pressures prohibitive of smelting in even the shallowest and most ferroan portion of its anatectic mantle, the body would have to be larger than roughly 690 km in diameter. A 400 km body would have approximately 12 vol% of the interior (or 13 vol% of the interior apart from the thermal “skin” that never undergoes anatexis) prone, if both extremely shallow and extremely ferroan, to mild smelting. Gasless anatexis also implies that this large parent body was compositionally, at least in terms of mg, grossly heterogeneous before anatexis, probably (in view of the oxygen isotopic diversity) as a result of mixed accretion.

ABSTRACT Objectives This study sets out to investigate the intergenerational associations between the body mass index (BMI) of parents and the body composition of their offspring. Methods The cross‐sectional data were analyzed for 511 parent–offspring trios from London and south‐east England. The offspring were aged 5–21 years. Parental BMI was obtained by recall and offspring fat mass and lean mass were obtained using the four‐component model. Multivariable regression analysis, with multiple imputation for missing paternal values was used. Sensitivity analyses for levels of non‐paternity were conducted. Results A positive association was seen between parental BMI and offspring BMI, fat mass index (FMI), and lean mass index (LMI). The mother's BMI was positively associated with the BMI, FMI, and LMI z‐scores of both daughters and sons and of a similar magnitude for both sexes. The father's BMI showed similar associations to the mother's BMI, with his son's BMI, FMI, and LMI z‐scores, but no association with his daughter. Sensitivity tests for non‐paternity showed that maternal coefficients remained greater than paternal coefficients throughout but there was no statistical difference at greater levels of non‐paternity. Conclusions We found variable associations between parental BMI and offspring body composition. Associations were generally stronger for maternal than paternal BMI, and paternal associations appeared to differ between sons and daughters. In this cohort, the mother's BMI was statistically significantly associated with her child's body composition but the father's BMI was only associated with the body composition of his sons. Am. J.

Restrictive feeding is associated with child overweight; however, the majority of studies used parent-report questionnaires. The relationship between child adiposity measures and directly observed parent and child behaviours were tested using a novel behavioural coding system (BCS). Data from 109 children, participants in a twin study and their mothers, were analyzed. Parent-child dyads were video-recorded twice in the laboratory, while children ate ad libitum from a buffet lunch. Mother and child behaviours were assessed using the BCS. Height, body weight and body fat were directly measured for each child. Associations between child adiposity measures and average BCS behaviour (i.e. pooled across visits) were tested using partial correlations adjusting for child age. Regarding discouragement prompts, child body mass index (BMI) z-score was significantly associated with a greater rate of total discouragements (per minute, min -1 ), nonverbal discouragements (min -1 ) and temporary (delay) discouragements (min -1 ) (p < 0.05). Child percent body fat was associated with greater nonverbal discouragements (min -1 ). Regarding encouragement prompts, child BMI z-score was significantly associated with a greater rate of total encouragements (min -1 ), nonverbal encouragements (min -1 ) and reward encouragements (min -1 ). Child BMI z-score and percent body fat were both positively associated with greater maternal health encouragements (min -1 ). Associations with encouragement to eat prompts were no longer significant when accounting for the dependence among twins (being part of the same family). Heavier children received greater maternal discouragements to eat and, with qualifications, encouragements to eat. The role of nonverbal parenting cues warrants further research regarding child eating regulation and obesity. © 2017 World Obesity Federation.

Iron meteorites are core fragments from differentiated and subsequently disrupted planetesimals. The parent bodies are usually assumed to have formed in the main asteroid belt, which is the source of most meteorites. Observational evidence, however, does not indicate that differentiated bodies or their fragments were ever common there. This view is also difficult to reconcile with the fact that the parent bodies of iron meteorites were as small as 20 km in diameter and that they formed 1-2 Myr earlier than the parent bodies of the ordinary chondrites. Here we show that the iron-meteorite parent bodies most probably formed in the terrestrial planet region. Fast accretion times there allowed small planetesimals to melt early in Solar System history by the decay of short-lived radionuclides (such as 26Al, 60Fe). The protoplanets emerging from this population not only induced collisional evolution among the remaining planetesimals but also scattered some of the survivors into the main belt, where they stayed for billions of years before escaping via a combination of collisions, Yarkovsky thermal forces, and resonances. We predict that some asteroids are main-belt interlopers (such as (4) Vesta). A select few may even be remnants of the long-lost precursor material that formed the Earth.

Planetary formation models show that terrestrial planets are formed by the accretion of tens of Moon- to Mars-sized planetary embryos through energetic giant impacts. However, relics of these large proto-planets are yet to be found. Ureilites are one of the main families of achondritic meteorites and their parent body is believed to have been catastrophically disrupted by an impact during the first 10 million years of the solar system. Here we studied a section of the Almahata Sitta ureilite using transmission electron microscopy, where large diamonds were formed at high pressure inside the parent body. We discovered chromite, phosphate, and (Fe,Ni)-sulfide inclusions embedded in diamond. The composition and morphology of the inclusions can only be explained if the formation pressure was higher than 20 GPa. Such pressures suggest that the ureilite parent body was a Mercury- to Mars-sized planetary embryo.

Collisional fragmentation of asteroids and its implication on the physical properties of Near-Earth Objects

NASA Astrophysics Data System (ADS)

Michel, P.

Collisions are at the origin of catastrophic disruptions in the asteroid Main Belt. This is witnessed by the observation of asteroid families, each composed of asteroids which originated from a single parent body, broken-up by a collision with another asteroid. Understanding the collisional process and its outcome properties is not only necessary in order to study the collisional evolution of small body population or the planetary formation, it is also strongly required in the context of mitigation strategies aimed at deviating a threatening asteroid. In the last three years, for the first time we have successfully performed numerical simulations of high speed collisions between small bodies which account for the production of gravitationally reaccumulated bodies. More precisely, we have developped a procedure which divides the process into two phases. Using a 3D SPH hydrocode, the fragmentation of the solid target through crack propagation is first computed. Then the simulation of the gravitational evolution and possible piecewise reaccumulation of the parent body is performed using the parallel N-body code pkdgrav. Our first simulations using monolithic parent bodies have succeeded in reproducing fundamental properties of some well-identified asteroid families, showing that gravitational re-accumulations following disruptive collisions are the key process accounting for the existence of asteroid families. Then, we have investigated the effect of the internal structure of the parent body on the outcome properties. We have thus shown that family parent bodies are likely to have already been pre-shattered by small impacts before being disrupted by a major event. We then suggested that the most likely internal structure of large asteroids in the main belt is not monolithic but rather composed of macroscopic fractures and voids. We will make a review of these simulations in three different impact regimes, from highly catastrophic to barely disruptive. In particular we will show the sensitivity of the resulting family characteristics upon the internal structure of the parent body. According to our current understanding, most NEOs are certainly fragments of larger asteroids of the Main Belt, injected either directly or by diffusion into main resonances that transported them to Earth-crossing orbits. According to our simulations, most NEOs with diameter larger than several hundreds of meters should then correspond to gravitational aggregates. Given the crucial role of the internal structure on the impact outcome, this has important implications in the development of efficient mitigation strategies.

Lifestyle Triple P is a general parenting intervention which focuses on preventing further excessive weight gain in overweight and obese children. The objective of the current study was to assess the effectiveness of the Lifestyle Triple P intervention in the Netherlands. We used a parallel randomized controlled design to test the effectiveness of the intervention. In total, 86 child-parent triads (children 4-8 years old, overweight or obese) were recruited and randomly assigned (allocation ratio 1:1) to the Lifestyle Triple P intervention or the control condition. Parents in the intervention condition received a 14-week intervention consisting of ten 90-minute group sessions and four individual telephone sessions. Primary outcome measure was the children's body composition (BMI z-scores, waist circumference and skinfolds). The research assistant who performed the measurements was blinded for group assignment. Secondary outcome measures were the children's dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, and parental self-efficacy. Outcome measures were assessed at baseline and 4 months (short-term) and 12 months (long-term) after baseline. Multilevel multiple regression analyses were conducted to determine the effect of the intervention on primary and secondary outcome measures. No intervention effects were found on children's body composition. Analyses of secondary outcomes showed positive short-term intervention effects on children's soft-drink consumption and parental responsibility regarding physical activity, encouragement to eat, psychological control, and efficacy and satisfaction with parenting. Longer-term intervention effects were found on parent's report of children's time spent on sedentary behavior and playing outside, parental monitoring food intake, and responsibility regarding nutrition. Although the Lifestyle Triple P intervention showed positive effects on some parent reported child behaviors and parenting measures, no effects were visible on children's body composition or objectively measured physical activity. Several adjustments of the intervention content are recommended, for example including a booster session. Nederlands Trial Register NTR 2555.

Children spend more time with electronic media than they do in any other activity, aside from sleep. Many of the negative effects that stem from media exposure may be reduced by parental monitoring of children's media use; however, there lacks a clear understanding of the mechanisms and extent of these protective effects. To determine the prospective effects of parental monitoring of children's media on physical, social, and academic outcomes. Prospective cohort design. Data were collected by in-home and in-school surveys in 2 communities in Iowa and Minnesota, where 1323 third- (n = 430), fourth- (n = 446), and fifth- (n = 423) grade students participated. A primary caregiver and teachers also provided data about the student. Participants in the current study were recruited to participate in a social ecological model-based obesity prevention program. Body mass index, average weekly sleep, school performance, prosocial behavior, and aggressive behavior. RESULTS Structural equation modeling revealed that parental monitoring of children's media influences children's sleep, school performance, and prosocial and aggressive behaviors and that these effects are mediated through total screen time and exposure to media violence. Parental monitoring of media has protective effects on a wide variety of academic, social, and physical child outcomes. Pediatricians and physicians are uniquely positioned to provide scientifically based recommendations to families; encouraging parents to monitor children's media carefully can have a wide range of health benefits for children.

Television (TV) viewing is popular among adults and children, and child TV-viewing time is positively associated with parent TV-viewing time. Efforts to limit the TV-viewing time of children typically target parent rule-setting. However, little is known about the association between parent TV-viewing practices and rule-setting. We used baseline height and weight data and survey data collected from 2011 through 2015 on parents and their 8- to 12-year-old children (N = 212 parent/child dyads) who were participants in 2 community-based obesity prevention intervention trials conducted in metropolitan Minnesota. Multivariable binary logistic regression analysis was used to assess the association between parent TV-viewing time on weekdays or weekend days (dichotomized as ≤2 hrs/d vs ≥2.5 hrs/d) and parent rules limiting child TV-viewing time. Child mean age was 10 (standard deviation [SD], 1.4) years, mean body mass index (BMI) percentile was 81 (SD, 16.7), approximately half of the sample were boys, and 42% of the sample was nonwhite. Parent mean age was 41 (SD, 7.5) years, and mean BMI was 29 (SD, 7.5); most of the sample was female, and 36% of the sample was nonwhite. Parents who limited their TV-viewing time on weekend days to 2 hours or fewer per day were almost 3 times more likely to report setting rules limiting child TV-viewing time than were parents who watched 2.5 hours or more per day (P = .01). A similar association was not seen for parent weekday TV-viewing time. For most adults and children, a meaningful decrease in sedentariness will require reductions in TV-viewing time. Family-based interventions to reduce TV-viewing time that target the TV-viewing practices of both children and parents are needed.

Isotopic abundance variations among meteorites are used to establish genetic associations between meteorite classes. Oxygen isotope distributions between group II E irons with H-group ordinary chondrites and enstatic meteorites indicate that the parent bodies were formed out of pre-solar material that was not fully mixed at the time condensation occurred within the solar nebula.

Meteoritic parent bodies - Nature, number, size and relation to present-day asteroids

NASA Technical Reports Server (NTRS)

Lipschutz, Michael E.; Gaffey, Michael J.; Pellas, Paul

1989-01-01

The relationship between meteoritic parent bodies and the present-day asteroids is discussed. Results on oxygen isotopic signatures and chemical distinctions among meteorite classes indicate that meteorites derive from a small number of parent bodies relative to the number of asteroids. The spectral properties of the ordinary chondrites and similar inclusions in meteoritic breccias differ from those of the abundant S asteroids (with no process known that can account for these differences); the closest spectral analogs of these chondrites are the rare near-earth Q-type asteroids. These facts lead to the question of why abundant meteorites have rare asteroidal analogs, while the abundant asteroids have rare meteoritic analogs. This question constitutes a prime topic for future studies.

Characteristics and formation of amino acids and hydroxy acids of the Murchison meteorite

1995-01-01

Eight characteristics of the unique suite of amino acids and hydroxy acids found in the Murchison meteorite can be recognized on the basis of detailed molecular and isotopic analyses. The marked structural correspondence between the alpha-amino acids and alpha-hydroxy acids and the high deuterium/hydrogen ratio argue persuasively for their formation by aqueous phase Strecker reactions in the meteorite parent body from presolar, i.e., interstellar, aldehydes, ketones, ammonia, and hydrogen cyanide. The characteristics of the meteoritic suite of amino acids and hydroxy acids are briefly enumerated and discussed with regard to their consonance with this interstellar-parent body formation hypothesis. The hypothesis has interesting implications for the organic composition of both the primitive parent body and the presolar nebula.

In this study, we aimed to assess the eating attitudes and stress coping styles of parents whose children presented to the clinic complaining of food refusal. The parents of 31 children aged ≥3 years, presented to the clinic with the complaint of food refusal. The control group consisted of 30 healthy children with no prior history of food refusal, and their parents. In both groups, birth features, body mass indexes (BMIs), eating attitudes and stress coping styles of the parents were assessed. The parents of both groups were studied, in part utilizing the eating attitudes test (EAT), and the coping styles of stress scale (CSSS). Our study found that body weights and BMI values of the fathers in the study group were significantly lower than fathers in the control group. There was no significant difference in EAT scores between the two groups; however, where the children's body weight and height for age percentile was under 25%, the parents had significantly lower EAT scores. When CSSS scores were assessed, the optimistic approach score of the mother and the self-confident score of the father were found to be significantly high in both groups. The parental perception and definition of eating problems does not necessarily indicate the presence of an eating disorder in a child. In fact, the eating attitudes of the fathers were related to the low percentile weight and height values of the children, and a child's food refusal was not dependent on the stress coping style used by the parent.

National Health Interview Survey data were utilized (N 2007  = 1225; N 2012  = 1835). Logistic regression examined associations between TCS-type and MBT-use, while propensity score matching controlled for confounders in the prematch sample. Compared with children without DCEBG, MBT-use was higher among children with DCEBG, but it decreased from 2007 (9.7%) to 2012 (5.1%). Receipt of school-based TCS increased from 2007 (11.3%) to 2012 (33.9%). Receipt of school-only TCS, compared with nonschool-only TCS, was associated with lower MBT-use (OR 2007  = 0.20; OR 2012  = 0.54). After matching, this difference remained for 2007 (t prematch  = -2.77; t postmatch  = -2.00), but not 2012 (t prematch  = -2.53; t postmatch  = -0.88). School-only TCS-use increased with family activity limitations; in 2012, it decreased with higher parental education. Mind-body techniques-use was higher in girls and associated with higher parental education and family activity limitations. While the relative increase of MBT integration by school-based TCS is commendable and further encouraged, school mental health practitioners should account for the differential effects of family-level factors on TCS-choice and MBT-use. © 2017, American School Health Association.

Paleomagnetic Evidence for Partial Differentiation of the Silicate-Bearing IIE Iron Meteorite Parent Body

The identification of dozens of petrologically diverse chondritic and achondritic meteoritic groups indicates that a diversity of planetesimals formed in the early solar system. It is commonly thought that planetesimals formed as either unmelted or else fully differentiated bodies, implying that chondrites and achondrites cannot have originated on a single body. However, it has been suggested that partially melted bodies with chondritic crusts and achondritic interiors may also have formed. This alternative proposal is supported by the recent identification of post-accretional remanent magnetization in CV, H chondrites, and also possibly in CM chondrites, which has been interpreted as possible evidence for a core dynamo on their parent bodies. Other piece of evidence suggesting the existence of partially differentiated bodies is the existence of the silicate-bearing IIE iron meteorites. The IIEs are composed of a Fe-Ni alloy matrix containing a mixture of chondritic, primitive achondritic, and chondritic silicate inclusions that likely formed on a single parent body. Therefore, IIEs may sample all three putative layers of a layered, partially differentiated body. On the other hand, the siderophile element compositions of the matrix metal demonstrate that it is not the product of fractional crystallization of a molten core. This suggests that the matrix metal is derived from isolated reservoirs of metal in the mantle and/or crust. It is unknown whether a large-scale metallic core, not represented by known meteorite samples, also formed on the same parent planetesimal. We can search for evidence of a molten, advecting core by assessing whether IIE irons contain remanent magnetization produced by a core dynamo. With this goal, we studied the paleomagnetism of a cloudy zone (CZ) interface in the Fe-Ni matrix of the IIE iron Colomera using X-ray photoelectron emission microscopy (XPEEM). Our initial results suggest that a steady, intense magnetic field was present during the gradual formation of the CZ. This may indicate the existence of an advecting core on the IIE parent body, which would support the hypothesis of a partially differentiated structure. We are continuing to test this conclusion with further XPEEM measurements on Colomera and other IIE irons.

2010-01-01

Parenting style and parental support and modeling of physical activity and healthy dietary intake have been linked to youth weight status, although findings have been inconsistent across studies. Furthermore, little is known about how these factors co-occur, and the influence of the co-existence of these factors on adolescents' weight. This paper examines the relationship between the co-occurrence of various parenting characteristics and adolescents' weight status. Data are from Project EAT, a population-based study of 4746 diverse adolescents. Theoretical and latent class groupings of parenting styles and parenting practices were created. Regression analyses examined the relationship between the created variables and adolescents' body mass index (BMI). Having an authoritarian mother was associated with higher BMI in sons. The co-occurrence of an authoritarian mother and neglectful father was associated with higher BMI for sons. Daughters' whose fathers did not model or encourage healthy behaviors reported higher BMIs. The co-occurrence of neither parent modeling healthy behaviors was associated with higher BMIs for sons, and incongruent parental modeling and encouraging of healthy behaviors was associated with higher BMIs in daughters. While further research into the complex dynamics of the home environment is needed, findings indicate that authoritarian parenting style is associated with higher adolescent weight status and incongruent parenting styles and practices between mothers and fathers are associated with higher adolescent weight status.

This umbrella review analysed the relationships between family variables and child/adolescent body weight, diet and physical activity. In line with theories of health behaviour change, it was assumed that behaviour-specific family variables (i.e. beliefs, perceptions and practices referring to food intake or physical activity) would have stronger support than more general family variables (i.e. socio-economic status or general parental practices). Data obtained from 18 systematic reviews (examining 375 quantitative studies) were analysed. Reviews of experimental trials generally supported the effectiveness of reward/positive reinforcement parental strategies, parental involvement in treatment or prevention programmes, and cognitive-behavioural treatment in reducing child/adolescent body mass and/or obesity. Results across reviews of correlational studies indicated that healthy nutrition of children/adolescents was related to only one parental practice (parental monitoring), but was associated with several behaviour-specific family variables (e.g. a lack of restrictive control over food choices, high intake of healthy foods and low intake of unhealthy foods by parents and siblings, low pressure to consume foods). With regard to adolescent physical activity, stronger support was also found for behaviour-specific variables (e.g. physical activity of siblings), and for certain socio-economic variables (e.g. parental education). Child and adolescent obesity prevention programmes should account for behaviour-specific family variables. © 2011 Blackwell Publishing Ltd.

PURPOSE.: The purpose of the study was to examine the feasibility and initial efficacies of parent- and/or child-focused online interventions and variables correlated with child body mass index percentile change. DESIGN AND METHODS.: A feasibility and cluster randomized controlled pilot study was used. RESULTS.: Recruitment was more effective at parent-teacher conferences compared with when materials were sent home with fifth- to eighth-grade culturally diverse students. Retention was 90% for students and 62-74% for parents. Authoritative parent feeding behaviors were associated with lower child body mass index. A larger study is warranted. PRACTICE IMPLICATIONS.: Online approaches may provide a feasible option for childhood obesity prevention and amelioration. © 2013, Wiley Periodicals, Inc.

IS THE LARGE CRATER ON THE ASTEROID (2867) STEINS REALLY AN IMPACT CRATER?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Morris, A. J. W.; Price, M. C.; Burchell, M. J., E-mail: m.j.burchell@kent.ac.uk

The large crater on the asteroid (2867) Steins attracted much attention when it was first observed by the Rosetta spacecraft in 2008. Initially, it was widely thought to be unusually large compared to the size of the asteroid. It was quickly realized that this was not the case and there are other examples of similar (or larger) craters on small bodies in the same size range; however, it is still widely accepted that it is a crater arising from an impact onto the body which occurred after its formation. The asteroid (2867) Steins also has an equatorial bulge, usually consideredmore » to have arisen from redistribution of mass due to spin-up of the body caused by the YORP effect. Conversely, it is shown here that, based on catastrophic disruption experiments in laboratory impact studies, a similarly shaped body to the asteroid Steins can arise from the break-up of a parent in a catastrophic disruption event; this includes the presence of a large crater-like feature and equatorial bulge. This suggests that the large crater-like feature on Steins may not be a crater from a subsequent impact, but may have arisen directly from the fragmentation process of a larger, catastrophically disrupted parent.« less

Paris vs. Murchison: Impact of hydrothermal alteration on organic matter in CM chondrites

Unravelling the origin of organic compounds that were accreted into asteroids requires better constraining the impact of asteroidal hydrothermal alteration on their isotopic signatures, molecular structures, and spatial distribution. Here, we conducted a multi-scale/multi-technique comparative study of the organic matter (OM) from two CM chondrites (that originate from the same parent body or from identical parent bodies that accreted the same mixture of precursors) and underwent a different degree of hydrothermal alteration: Paris (a weakly altered CM chondrite - CM 2.8) and Murchison (a more altered one - CM 2.5). The Paris insoluble organic matter (IOM) shows a higher aliphatic/aromatic carbon ratio, a higher radical abundance and a lower oxygen content than the Murchison IOM. Analysis of the OM in situ shows that two texturally distinct populations of organic compounds are present within the Paris matrix: sub-micrometric individual OM particles and diffuse OM finely distributed within phyllosilicates and amorphous silicates. These results indicate that hydrothermal alteration on the CM parent body induced aromatization and oxidation of the IOM, as well as a decrease in radical and nitrogen contents. Some of these observations were also reported by studies of variably altered fragment of Tagish Lake (C2), although the hydrothermal alteration of the OM in Tagish Lake was apparently much more severe. Finally, comparison with data available in the literature suggests that the parent bodies of other chondrite petrologic groups could have accreted a mixture of organic precursors different from that accreted by the parent body of CMs.

Family based-treatments have the most empirical support in the treatment of adolescent anorexia nervosa; yet, a significant percentage of adolescents and their families do not respond to manualized family based treatment (FBT). The aim of this open trial was to conduct a preliminary evaluation of an innovative family-based approach to the treatment of anorexia: Acceptance-based Separated Family Treatment (ASFT). Treatment was grounded in Acceptance and Commitment Therapy (ACT), delivered in a separated format, and included an ACT-informed skills program. Adolescents (ages 12-18) with anorexia or sub-threshold anorexia and their families received 20 treatment sessions over 24 weeks. Outcome indices included eating disorder symptomatology reported by the parent and adolescent, percentage of expected body weight achieved, and changes in psychological acceptance/avoidance. Half of the adolescents (48.0%) met criteria for full remission at the end of treatment, 29.8% met criteria for partial remission, and 21.3% did not improve. Overall, adolescents had a significant reduction in eating disorder symptoms and reached expected body weight. Treatment resulted in changes in psychological acceptance in the expected direction for both parents and adolescents. This open trial provides preliminary evidence for the feasibility, acceptability, and efficacy of ASFT for adolescents with anorexia. Directions for future research are discussed.

To present athletic trainers with recommendations for safe weight loss and weight maintenance practices for athletes and active clients and to provide athletes, clients, coaches, and parents with safe guidelines that will allow athletes and clients to achieve and maintain weight and body composition goals. Unsafe weight management practices can compromise athletic performance and negatively affect health. Athletes and clients often attempt to lose weight by not eating, limiting caloric or specific nutrients from the diet, engaging in pathogenic weight control behaviors, and restricting fluids. These people often respond to pressures of the sport or activity, coaches, peers, or parents by adopting negative body images and unsafe practices to maintain an ideal body composition for the activity. We provide athletic trainers with recommendations for safe weight loss and weight maintenance in sport and exercise. Although safe weight gain is also a concern for athletic trainers and their athletes and clients, that topic is outside the scope of this position statement. Athletic trainers are often the source of nutrition information for athletes and clients; therefore, they must have knowledge of proper nutrition, weight management practices, and methods to change body composition. Body composition assessments should be done in the most scientifically appropriate manner possible. Reasonable and individualized weight and body composition goals should be identified by appropriately trained health care personnel (eg, athletic trainers, registered dietitians, physicians). In keeping with the American Dietetics Association (ADA) preferred nomenclature, this document uses the terms registered dietitian or dietician when referring to a food and nutrition expert who has met the academic and professional requirements specified by the ADA's Commission on Accreditation for Dietetics Education. In some cases, a registered nutritionist may have equivalent credentials and be the commonly used term. All weight management and exercise protocols used to achieve these goals should be safe and based on the most current evidence. Athletes, clients, parents, and coaches should be educated on how to determine safe weight and body composition so that athletes and clients more safely achieve competitive weights that will meet sport and activity requirements while also allowing them to meet their energy and nutritional needs for optimal health and performance.

Early aqueous activity on the ordinary and carbonaceous chondrite parent bodies recorded by fayalite

Doyle, Patricia M.; Jogo, Kaori; Nagashima, Kazuhide

Here, chronology of aqueous activity on chondrite parent bodies constrains their accretion times and thermal histories. Radiometric 53Mn– 53Cr dating has been successfully applied to aqueously formed carbonates in CM carbonaceous chondrites. Owing to the absence of carbonates in ordinary (H, L and LL), and CV and CO carbonaceous chondrites, and the lack of proper standards, there are no reliable ages of aqueous activity on their parent bodies. Here we report the first 53Mn– 53Cr ages of aqueously formed fayalite in the L3 chondrite Elephant Moraine 90161 as 2.4 +1.8 -1.3 Myr after calcium–aluminium-rich inclusions (CAIs), the oldest Solar Systemmore » solids. In addition, measurements using our synthesized fayalite standard show that fayalite in the CV3 chondrite Asuka 881317 and CO3-like chondrite MacAlpine Hills 88107 formed and 4.2 +0.8 -0.7 Myr after CAIs, respectively. Thermal modelling, combined with the inferred conditions (temperature and water/rock ratio) and 53Mn– 53Cr ages of aqueous alteration, suggests accretion of the L, CV and CO parent bodies ~1.8–2.5 Myr after CAIs.« less

Impact of Radiogenic Heating on the Formation Conditions of Comet 67P/Churyumov–Gerasimenko

DOE Office of Scientific and Technical Information (OSTI.GOV)

Mousis, O.; Drouard, A.; Vernazza, P.

2017-04-10

Because of the high fraction of refractory material present in comets, the heat produced by the radiogenic decay of elements such as aluminum and iron can be high enough to induce the loss of ultravolatile species such as nitrogen, argon, or carbon monoxide during their accretion phase in the protosolar nebula (PSN). Here, we investigate how heat generated by the radioactive decay of {sup 26}Al and {sup 60}Fe influences the formation of comet 67P/Churyumov–Gerasimenko, as a function of its accretion time and the size of its parent body. We use an existing thermal evolution model that includes various phase transitions,more » heat transfer in the ice-dust matrix, and gas diffusion throughout the porous material, based on thermodynamic parameters derived from Rosetta observations. Two possibilities are considered: either, to account for its bilobate shape, 67P/Churyumov–Gerasimenko was assembled from two primordial ∼2 km sized planetesimals, or it resulted from the disruption of a larger parent body with a size corresponding to that of comet Hale–Bopp (∼70 km). To fully preserve its volatile content, we find that either 67P/Churyumov–Gerasimenko’s formation was delayed between ∼2.2 and 7.7 Myr after that of Ca–Al-rich Inclusions in the PSN or the comet’s accretion phase took place over the entire time interval, depending on the primordial size of its parent body and the composition of the icy material considered. Our calculations suggest that the formation of 67P/Churyumov–Gerasimenko is consistent with both its accretion from primordial building blocks formed in the nebula or from debris issued from the disruption of a Hale–Bopp-like body.« less

Ar-Ar and I-Xe Ages of Caddo County and Thermal History of IAB Iron Meteorites

NASA Technical Reports Server (NTRS)

Bogard, Donald D.; Garrison, Daniel H.; Takeda, Hiroshi

2005-01-01

Inclusions in IAB iron meteorites include non-chondritic silicate and those with more primitive chondritic silicate composition. Coarse-grained gabbroic material rich in plagioclase and diopside occurs in the Caddo County IAB iron meteorite and represents a new type of chemically differentiated, extra-terrestrial, andesitic silicate. Other parts of Caddo contain mostly andesitic material. Caddo thus exhibits petrologic characteristics of parent body metamorphism of a chondrite-like parent and inhomogeneous segregation of melts. Proposed IAB formation models include parent body partial melting and fractional crystallization or incomplete differentiation due to internal heat sources, and impact/induced melting and mixing. Benedix et al. prefer a hybrid model whereby the IAB parent body largely melted, then underwent collisional breakup, partial mixing of phases, and reassembly. Most reported 129I- Xe-129 ages of IABs are greater than 4.56 Gyr and a few are greater than or = 4.567 Gyr. These oldest ages exceed the 4.567 Gyr Pb-Pb age of Ca, Al-rich inclusions in primitive meteorites,

We investigated the relationships among early childhood caries (ECC), mouth pain, and nutritional status in children aged 1 to 6 years in Southern and Central Vietnam. A total of 593 parent-child pairs were recruited from 5 kindergartens or preschools in Ho-Chi Minh City and Da Nang. Parents completed surveys about dietary habits, oral health practices, and children's mouth pain experience; children received anthropometric assessment and dental examinations. There was a high prevalence of dental caries (74.4%), mostly untreated, and mouth pain (47.1%). Moderate correlations were found between parents' and children's consumption of soda (ρ = 0.361; P < .001) and salty snacks (ρ = 0.292; P < .001). Severity of ECC was associated with decreased weight- and body mass index-for-age z-scores. Presence of pulp-involved caries was associated with strikingly lower height-for-age (mean difference = 0.66; P = .001), weight-for-age (mean difference = 1.17; P < .001), and body mass index-for-age (mean difference = 1.18; P < .001) z-scores. Mouth pain was associated with lower body mass index-for-age z-scores (mean difference = 0.29; P = .013). ECC might negatively affect children's nutritional status, which might be mediated by the depth of decay, chronic inflammation, and mouth pain. Family-based and prevention-oriented nutrition and oral health programs are needed and should start during pregnancy and infancy.

There have been few randomized clinical trials (RCTs) for adolescents with anorexia nervosa (AN). Most of these posit that involving all family members in treatment supports favorable outcomes. However, at least 2 RCTs suggest that separate parent and adolescent sessions may be just as effective as conjoint treatment. This study compared the relative efficacy of family-based treatment (FBT) and parent-focused treatment (PFT). In PFT, the therapist meets with the parents only, while a nurse monitors the patient. Participants (N = 107) aged 12 to 18 years and meeting DSM 4(th)Edition criteria for AN or partial AN were randomized to either FBT or PFT. Participants were assessed at baseline, end of treatment (EOT), and at 6 and 12 months posttreatment. Treatments comprised 18 outpatient sessions over 6 months. The primary outcome was remission, defined as ≥95% of median body mass index and Eating Disorder Examination Global Score within 1 SD of community norms. Remission was higher in PFT than in FBT at EOT (43% versus 22%; p = .016, odds ratio [OR] = 3.03, 95% CI = 1.23-7.46), but did not differ statistically at 6-month (PFT 39% versus FBT 22%; p = .053, OR = 2.48, CI = 0.989-6.22), or 12-month (PFT 37% versus FBT 29%; p = .444, OR = 1.39, 95% CI = 0.60-3.21) follow-up. Several treatment effect moderators of primary outcome were identified. At EOT, PFT was more efficacious than FBT in bringing about remission in adolescents with AN. However, differences in remission rates between PFT and FBT at follow-up were not statistically significant.

Parenting style as a predictor of adolescent weight and weight-related behaviors.

PubMed

Berge, Jerica M; Wall, Melanie; Loth, Katie; Neumark-Sztainer, Dianne

2010-04-01

Current research indicates that specific parenting styles are associated with adolescent overweight, dietary intake, and physical activity; but most of the research has been cross-sectional, making it difficult to determine the temporal order of these associations. The current study adds to the previous research by examining 5-year longitudinal associations between parenting style and adolescent weight and weight-related behaviors. Data from Project EAT, a population-based study with adolescents from diverse ethnic and socioeconomic backgrounds, were used. Adolescents (N = 2,516) from 31 Minnesota schools completed in-class assessments in 1999 (Time 1) and mailed surveys in 2004 (Time 2). Multiple linear regression models were used to predict mean levels of adolescent outcomes at Time 2 from parenting style at Time 1. Time 1 maternal authoritative parenting style predicted lower body mass index in adolescent sons and daughters at Time 2. Time 1 paternal permissive parenting style predicted more fruits and vegetables intake in daughters at Time 2. Significant associations were not found between parenting style and adolescent physical activity. Findings suggest that authoritative parenting style may play a protective role related to adolescent overweight and that the dimension of warmth and/or caring in the parent-adolescent relationship may be important in relation to female adolescent healthy dietary intake. Further exploration of opposite sex parent-adolescent dyad patterns related to parenting style and adolescent weight and weight-related behaviors is warranted.

Meteorite regolith breccias are clastic rocks which formed by lithification of fragmental regolith material that once resided at the surface of a meteorite parent body. A study is reported of the matrix and 21 clasts of various sizes (0.2-24 mm) in the Dimmitt H chondrite regolith breccia using petrographic and electron microprobe techniques. In addition, oxygen isotope studies of three clasts and instrumental neutron activation analysis (INAA) and Ar-39/Ar-40 age dating of one clast are reported. The Dimmitt meteorite was found about 1942 near Dimmitt, Texas. Attention is given to analytical procedures, the clastic matrix, equilibrated clasts, poikilitic melt-rock clast, clasts of different chondrite groups, graphite-magnetite aggregates, the origin of exotic clasts, and the complexity of parent body surfaces processes.

Space Weathering of Ordinary Chondrite Parent Bodies, Its Impact on the Method of Distinguishing H, L, and LL Types and Implications for Itokawa Samples Returned by the Hayabusa Mission

As the most abundance meteorites in our collections, ordinary chondrites potentially have very important implications on the origin and formation of our Solar System. In order to map the distribution of ordinary chondrite-like asteroids through remote sensing, the space weathering effects of ordinary chondrite parent bodies must be addressed through experiments and modeling. Of particular importance is the impact on distinguishing different types (H/L/LL) of ordinary chondrites. In addition, samples of asteroid Itokawa returned by the Hayabusa spacecraft may re veal the mechanism of space weathering on an LLchondrite parent body. Results of space weathering simulations on ordinary chondrites and implications for Itokawa samples are presented here.

Objective Overweight among adolescents is not only an important public health problem but also a problem affecting economic growth in developing countries. The aim of this study was to investigate the parental determinants of overweight and obesity in Iranian adolescents at national level. Methods This cross sectional study was conducted within the framework of the Comprehensive Study on Household Food Consumption Patterns and Nutritional Status of IR Iran during 2001-2003. In adolescents, anthropometric indices were defined based on the CDC 2000 cut-off points for age and gender-specific body mass index (BMI). Parental characteristics were collected by questionnaire. Among the 7158 participating households, data on 7908 adolescents aged 11-19 years (3750 girls and 4158 boys) was analyzed. Findings The prevalence of overweight (85–94th percentile) in boys and girls was 6.2%, and 8.7%, respectively. The prevalence of obesity (≥95th percentile) among boys and girls was similar (3.3%). Parents’ weight status, father's job and parents’ education showed significant association with weight status in adolescents. Logistic regression analysis showed that parental overweight and obesity, parental education and father's job were the main parental determinants of overweight and obesity in Iranian adolescents. Conclusion Parental overweight and obesity, parental education and father's job seem to be the major parental determinants of overweight in Iranian adolescents. Future prevention programs must take these risk factors into account. PMID:23056857

The purposes of this study were (1) to examine parental perception of childhood obesity and race with measured body mass index (BMI), (2) to determine if parents are receptive to obesity screening in the pediatric emergency department and if receptivity varies by race or weight status, and (3) to determine eating habits that are predictors of obesity. This study is a cross-sectional study, with a convenience sample of 213 patients (aged 4-16 years accompanied by a parent/legal guardian to a pediatric emergency department). Weight and height were obtained, and parents were asked to complete a survey about perception of their child's weight, nutrition, and exercise habits. The current study found that parent perception of weight status was fairly accurate, and perception was predictive of BMI. Race, however, was not predictive of BMI. Parents were generally receptive of weight screening in the pediatric emergency department, and this did not vary as a function of weight status; however, receptivity did vary based on ethnicity, with African American parents being more receptive than white parents. Large portion sizes and the number of times a child eats fast food per week were found to be predictive of obesity. Greater than half of the children presenting to our pediatric emergency department were overweight or obese. Parents were generally accurate in their perception of their child's weight but were still receptive to obesity prevention and screening in the pediatric emergency department.

We aimed to assess the associations between parental history of hypertension and indicators of cardiovascular risk (retinal vessel diameter, presence of obesity, and elevated blood pressure) in prepubertal children. There were 1739 (77.7% of those eligible) 6-year-old students (863 girls and 876 boys) who were examined from a random cluster sample of 34 Sydney schools. Parents completed questionnaires about their medical conditions, including whether they have/had hypertension. Retinal images were taken with a digital fundus camera, and retinal vessel caliber was quantified using computer software. Anthropometric (height, weight, percentage of body fat, and body mass index) and blood pressure measures were collected. There were 160 children (9.2%) with a positive parental history of hypertension (either biological mother and/or father). Children with a positive versus negative parental history of hypertension had significantly higher body mass index (16.8 versus 16.5 kg/m(2); P=0.04) and systolic blood pressure (101.3 versus 99.8 mm Hg; P=0.01). Girls with positive versus negative parental history of hypertension had significantly higher diastolic blood pressure (≈3.1 mm Hg; P=0.01) and narrower retinal arteriolar caliber (≈4.3 μm; P=0.0004). Positive parental history of hypertension was not associated with mean retinal vascular caliber among boys. We show that a positive parental history of hypertension in healthy prepubertal girls, but not boys, is associated with narrower retinal arteriolar vessels, likely conveying a predisposition to develop hypertension later in life. These findings may indicate the need for cardiovascular disease prevention measures starting early in life among offspring of hypertensive parents.

Parental bonds, attachment anxiety, media susceptibility, and body dissatisfaction: a mediation model.

Patton, Sarah C; Beaujean, A Alexander; Benedict, Helen E

2014-08-01

The developmental trajectory of body image dissatisfaction is unclear. Researchers have investigated sociocultural and developmental risk factors; however, the literature needs an integrative etiological model. In 2009, Cheng and Mallinckrodt proposed a dual mediation model, positing that poor-quality parental bonds, via the mechanisms of heightening romantic attachment anxiety and thin-ideal media internalization, increases body dissatisfaction. We tested 2 versions of this model, including an alternate model featuring attachment anxiety in close friendships. We recruited females ages 12-24, primarily from a mid-sized private religious university, to complete self-report measures. The participant sample was ethnically diverse, with approximately 40% endorsing minority status. Results showed that mother care and father care were negatively linked to friendship attachment anxiety and romantic attachment anxiety. Friendship and romantic attachment anxiety were positively linked to media susceptibility. Media susceptibility was positively linked to body image dissatisfaction. Mother care and father care were negatively, indirectly linked to body image dissatisfaction through the mediators of friendship attachment anxiety and media susceptibility. Mother care made a significant, albeit small, contribution to body image dissatisfaction after controlling for other variables. Overall, findings suggest that adverse parent-child relational factors may indirectly elevate body dissatisfaction, operating through attachment anxiety and susceptibility to sociocultural pressures.

2016-12-01

This study sought to explore parental perceptions of body image in preschoolers. We conducted semi-structured interviews with 30 primary caregivers of preschoolers to examine knowledge, beliefs, and strategies regarding early body image socialization in families. Thematic Analysis yielded three themes highlighting knowledge gaps, belief discrepancies, and limited awareness of strategies. Findings regarding knowledge: Most participants defined body image as objective attractiveness rather than subjective self-assessment (53%) and focused on negative body image. Beliefs: Although 97% of participants believed weight and shape impact children's self-esteem, 63% believed preschoolers too young to have a body image. Strategies: Most participants (53%) said family was a primary influence on body image, but identified few effective strategies and 63% said they did not do anything to influence children's body image. Findings suggested family body image socialization in preschoolers is occurring outside the awareness of parents and the concept of positive body image is underdeveloped.

Brood desertion by female shorebirds: a test of the differential parental capacity hypothesis on Kentish plovers.

Amat, J A; Visser, G H; Pérez-Hurtado, A; Arroyo, G M

2000-01-01

The aim of this study was to examine whether the energetic costs of reproduction explain offspring desertion by female shorebirds, as is suggested by the differential parental capacity hypothesis. A prediction of the hypothesis is that, in species with biparental incubation in which females desert from brood care after hatching, the body condition of females should decline after laying to a point at which their body reserves are too low for continuing parental care. We tested this prediction on Kentish plovers (Charadrius alexandrinus) in which both sexes incubate but the females desert from brood care before the chicks fledge. We found no changes in either the body masses or body compositions of both individual male and female plovers from early incubation and throughout early chick rearing. Furthermore, the timing of brood desertion by females was not affected by their body condition. Neither did we find gender differences in the energetic costs of incubation. There were no differences in the timing of brood desertion between experimental and control females in an experiment in which we lengthened or shortened the duration of incubation by one week. These results indicate that energetic costs do not explain offspring desertion by female Kentish plovers and that the needs of chicks for parental care rather than cumulative investment by females is what determines the timing of brood desertion.

In this work we extend the systematic investigation of impact outcomes of 100-km-diameter targets started by Durda et al. (2007) and Benavidez et al. (2012) to targets of D = 400 km using the same range of impact conditions and two internal structures: monolithic and rubble-pile. We performed a new set of simulations in the gravity regime for targets of 400 km in diameter using these same internal structures. This provides a large set of 600 simulations performed in a systematic way that permits a thorough analysis of the impact outcomes and evaluation of the main features of the size frequency distribution due mostly to self-gravity. In addition, we use the impact outcomes to attempt to constrain the impact conditions of the asteroid belt where known asteroid families with a large expected parent body were formed. We have found fairly good matches for the Eunomia and Hygiea families. In addition, we identified a potential acceptable match to the Vesta family from a monolithic parent body of 468 km. The impact conditions of the best matches suggest that these families were formed in a dynamically excited belt. The results also suggest that the parent body of the Eunomia family could be a monolithic body of 382 km diameter, while the one for Hygiea could have a rubble-pile internal structure of 416 km diameter.

Seahorses, together with the pipefishes (Family Syngnathidae), are the only vertebrates in which embryonic development takes place within a specialised body compartment, the brood pouch, of the male instead of the female. Embryos develop in close association with the brood pouch epithelium in a manner that bears some resemblance to embryo-placental relationships in mammals. We have explored the hypothesis that parental body size and age should affect offspring postnatal growth and survival if brood pouch quality impacts upon prenatal embryonic nutrition or respiration. Using an aquarium population of the yellow seahorse, Hippocampus kuda, we show here that large parents produce offspring whose initial postnatal growth rates (weeks one to three) were significantly higher than those of the offspring of younger and smaller parents. Whereas 90% of offspring from the larger parents survived for the duration of the study (7 weeks), less that 50% of offspring from smaller parents survived for the same period. For the offspring of large parents, growth rates from individual males were negatively correlated with the number of offspring in the cohort (r=-0.82; P<0.05); this was not the case for offspring from small parents (r=0.048; P>0.9). Observations of embryos within the pouch suggested that when relatively few embryos are present they may attach to functionally advantageous sites and thus gain physiological support during gestation. These results suggest that male body size, and pouch size and function, may influence the future fitness and survival of their offspring.

Can we trust what parents tell us? A systematic review.

Taking a history is a key diagnostic instrument in paediatric consultations. Numerous issues potentially reduce the history's reliability. Therefore, paediatricians have always expressed ambivalence regarding history taking from parents, both valuing and distrusting it. In this review, we describe how parents build and present a description of their child's health issues in the conceptual framework of self-regulation theory. We performed a systematic review on the literature on the reliability of history taking. No studies examined the reliability of history taking from parents, but there is a considerable body of evidence on the issue of mutual trust in relationships between health care professionals and patients. Because trust is a dynamic relational phenomenon, taking a patient centred approach in consultations is likely to increase the patients' and parents' trust in the health care professional, and their willingness to follow the health care professional's treatment proposals. We provide evidence based recommendations on how to build and maintain trust in paediatric consultations by taking a patient centred approach in such consultations. Copyright © 2017.

Parental investment strategies are considered to represent a trade-off between the benefits of investment in current offspring and costs to future reproduction. Due to their high residual reproductive value, long-lived organisms are predicted to be more reluctant to increase parental effort. 2. We tested the hypothesis that breeding little auks (Alle alle) have a fixed level of reproductive investment, and thus reduce parental effort when costs associated with reproduction increase. 3. To test this hypothesis we experimentally increased the flight costs of breeding little auks via feather clipping. In 2005 we examined changes in the condition of manipulated parents, of the mates of manipulated parents, and of their chick as direct measures of change in parental resource allocation between self-maintenance and current reproduction. In 2007 we increased sample sizes to determine whether there was a physiological cost (elevated corticosterone, CORT) associated with the manipulation. 4. We found that: (i) clipped birds and their mates lost more body mass than controls, but there was no difference in mass loss between members of a pair; (ii) clipped birds had higher CORT levels than control birds; (iii) there were no inter-annual differences in body mass and CORT levels between clipped individuals and their mates at recapture, and (iv) chicks with a clipped parent had lower peak and fledging mass, and higher CORT levels than control chicks in both years. 5. Contrary to our hypothesis, the reduction in body mass of partners to clipped birds suggests that little auks can increase parental effort to some extent. Nonetheless, the lower fledging mass and higher CORT of chicks with a clipped parent indicates provisioning rates may not have been fully maintained. 6. As predicted by life-history theory, there may be a threshold to the additional reproductive costs breeders will accept, with parents prioritizing self-maintenance over increased provisioning effort when foraging costs become too high. ?? 2008 British Ecological Society.

A cross-sectional analysis of parents' and patients' perceptions of deformity- and brace-related stress regarding conservative treatment of adolescent idiopathic scoliosis. The purpose of this study was to determine the agreement between patients' and parents' assessments of emotional stress and to compare these assessments with radiographical measurements of spinal deformity. Conservative treatment in patients with scoliosis may cause emotional stress. To our knowledge, no group has ever reported patient and parental estimation of stress related to wearing a brace and spinal deformity in girls with adolescent idiopathic scoliosis. Sixty-three pairs of parents and girls with adolescent idiopathic scoliosis treated with a Cheneau brace were separately asked to complete the Bad Sobberheim Stress Questionnaire-Deformity and the Bad Sobberheim Stress Questionnaire-Brace. The age range of the patients was from 10 to 17 years. Patients were assessed at a mean of 14.12 (SD, 10.99) months after the start of the conservative treatment. Patients thought that a moderate level of stress was connected with conservative treatment; however, the stress level, related to perceived trunk deformation, was low. From the parents' perspective, patients experienced a moderate level of stress during conservative treatment and related to spinal deformity. The study groups differ in their perception of stress levels due to body disfigurement but not during the conservative treatment. Parent-patient stress-level disparities were not related to body mass index, age of the patient, brace application, and radiographical measurements of spinal deformity. Patients and parents perceive the emotional stress related to brace treatment in the same way; however, parents overestimate the assessment of stress levels related to body deformity. From the perspective of patients and parents, brace wearing increased the level of stress induced by the deformity alone. Complete assessment of conservative treatment should include evaluation of emotional stress from the perspective of patients and parents.

The recently developed body-wide Automatic Anatomy Recognition (AAR) methodology depends on fuzzy modeling of individual objects, hierarchically arranging objects, constructing an anatomy ensemble of these models, and a dichotomous object recognition-delineation process. The parent-to-offspring spatial relationship in the object hierarchy is crucial in the AAR method. We have found this relationship to be quite complex, and as such any improvement in capturing this relationship information in the anatomy model will improve the process of recognition itself. Currently, the method encodes this relationship based on the layout of the geometric centers of the objects. Motivated by the concept of virtual landmarks (VLs), this paper presents a new one-shot AAR recognition method that utilizes the VLs to learn object relationships by training a neural network to predict the pose and the VLs of an offspring object given the VLs of the parent object in the hierarchy. We set up two neural networks for each parent-offspring object pair in a body region, one for predicting the VLs and another for predicting the pose parameters. The VL-based learning/prediction method is evaluated on two object hierarchies involving 14 objects. We utilize 54 computed tomography (CT) image data sets of head and neck cancer patients and the associated object contours drawn by dosimetrists for routine radiation therapy treatment planning. The VL neural network method is found to yield more accurate object localization than the currently used simple AAR method.

The aim of this study was to investigate the prevalence of overweight/obesity among parents of children entering childhood obesity treatment and to evaluate changes in the parents' weight statuses during their child's treatment. The study included parents of 1,125 children and adolescents aged 3-22 years, who were enrolled in a multidisciplinary childhood obesity treatment program. At baseline, weight and height of the parents were obtained by self-reported information and parental body mass index (BMI) was calculated. Weight and height of the children were measured in the clinic and BMI standard deviation scores were calculated. Furthermore, anthropometric data from parents of 664 children were obtained by telephone interview after a mean of 2.5 years of treatment (ranging 16 days to 7 years), and changes in parental BMI were analyzed. Data on changes in BMI were available in 606 mothers and 479 fathers. At baseline, the median BMI of the mothers was 28.1 kg/m2 (range: 16.9-66.6), and the median BMI of the fathers was 28.9 kg/m2 (range: 17.2-48.1). Seventy percent of the mothers and 80% of the fathers were overweight or obese at the time of their child's treatment initiation. Both the mothers and fathers lost weight during their child's treatment with a mean decrease in BMI in the mothers of 0.5 (95% CI: 0.2-0.8, p = 0.0006) and in the fathers of 0.4 (95% CI: 0.2-0.6, p = 0.0007). Of the overweight/obese parents, 60% of the mothers and 58% of the fathers lost weight during their child's treatment. There is a high prevalence of overweight/obesity among parents of children entering childhood obesity treatment. Family-based childhood obesity treatment with a focus on the child has a positive effect on parental BMI with both mothers and fathers losing weight. ClinicalTrials.gov NCT00928473.

Facial and bodily correlates of family background.

It has been suggested that absence of the father during early childhood has long-reaching effects on reproductive strategy and development of offspring. This paper reports two studies designed to investigate the physical characteristics of daughters associated with father absence. Study 1 used a facial averaging method to produce composite images of faces of women whose parents separated during their childhood (who were 'father absent'), women whose parents remained together, but had poor quality relationships and women whose parents were together and had good quality relationships. Images were then rated by male and female judges. Father absence and poor parental relationships were associated with apparent facial masculinity and reduced attractiveness in daughters. Poor parental relationships were also associated with reduced apparent health. Study 2 compared family background with body measurements and found that father absence or a poor quality relationship between parents were associated with body masculinity (high waist-to-hip ratio) and increased weight-for-height and adiposity. These results highlight the possibility of physical masculinization being associated with purported father absence 'effects'.

2016-06-01

Mindfulness meditation is a useful adjunct to behavioral and medical interventions to manage a range of symptoms, including psychological and physical responses to stress, anxiety, depression, and disruptive behavior. Mindfulness approaches can be taught to children, adolescents, and their parents to improve self-regulation, particularly in response to stress. Mindfulness may be particularly relevant for youth and families who have an increased risk for exposure to chronic stress and unique stressors associated with medical and/or social-contextual considerations. Moreover, mindfulness parenting techniques can augment traditional behavioral approaches to improve children׳s behavior through specific parent-child interactions. A growing body of empirical studies and clinical experience suggest that incorporating mindfulness practices will enable clinicians to more effectively treat youth and their families in coping optimally with a range of challenging symptoms.

The study aimed to assess adolescent patterns of eating habits, determine factors influencing these patterns, and identify male and female differences related to eating habits. Using a cross-sectional study approach, a sample of adolescents ( N = 423) in randomly selected clusters chosen from government and private schools in the south of Jordan completed self-administered questionnaires relating to socio-demographic data and personal eating habits. Results showed that parents, peers, and mass media are contributing factors, with peer pressure likely outweighing parental guidance. Males were more likely to be influenced by peers than females, whereas females were more likely to be influenced by media-based advertising. Lower body mass indices correlate with eating breakfast, which a majority of adolescents reported they do not do. Interventions targeted toward improving eating and active behaviors should involve peers as well as parents.

The purpose of this quasi-experimental study was to assess the efficacy of a family-based (FB) weight-loss and behavior-modification intervention among overweight/obese children (age 9-11 years) and their parents in Taiwan. The intervention group (52 child-parent dyads) participated in an FB program for 7 weeks. The control group (55 child-parent dyads) received an educational pamphlet about obesity prevention. The children's body mass index (BMI) z-scores were the primary outcome variable. The parents' BMI, high-calorie (HC) food-intake behaviors, screen-related behaviors, and restrictions on children's consumption of HC foods and screen-related behaviors and the availability of HC foods at home were the secondary outcome variables. Outcome variables were measured at baseline (T0), at the end of the intervention (T1), and 4 weeks after the end of the intervention (T2). A linear mixed model was used to assess the efficacy of the FB program. Results indicated that the children's BMI z-scores decreased significantly more from T0 to T2 in the experimental group than in the control group. The decreases in parents' HC food-intake behaviors and availability of HC foods at home and the increase in parental restrictions on children's consumption of HC foods were significantly greater in the experimental than in the control group from T0 to T1 and T0 to T2. The FB program was effective in modifying parental behaviors and the weight of overweight/obese children in a Taiwanese population. © The Author(s) 2015.

There is a paucity of studies evaluating targeted obesity prevention interventions in pre-school children. We conducted a randomized controlled trial to evaluate the efficacy of a parent-based obesity prevention intervention for pre-schoolers - MEND (Mind, Exercise, Nutrition … Do It!) 2-4 on child diet, eating habits, physical activity/sedentary behaviours, and body mass index (BMI). Parent-child dyads attended 10 weekly 90-min workshops relating to nutrition, physical activity and behaviours, including guided active play and healthy snack time. Assessments were conducted at baseline, immediately post-intervention, and 6 and 12 months post-intervention; child intake of vegetables, fruit, beverages, processed snack foods, fussiness, satiety responsiveness, physical activity, sedentary behaviour and neophobia were assessed via parent proxy report. Parent and child height and weight were measured. Two hundred one parent-child dyads were randomized to intervention (n = 104) and control (n = 97). Baseline mean child age was 2.7 (standard deviation [SD] 0.6) years, and child BMI-for-age z-score (World Health Organization) was 0.66 (SD 0.88). We found significant positive group effects for vegetable (P = 0.01) and snack food (P = 0.03) intake, and satiety responsiveness (P = 0.047) immediately post-intervention. At 12 months follow-up, intervention children exhibited less neophobia (P = 0.03) than controls. Future research should focus on additional strategies to support parents to continue positive behaviour change. ACTRN12610000200088. © 2015 World Obesity.

The Children and Parents in Focus project: a population-based cluster-randomised controlled trial to prevent behavioural and emotional problems in children

PubMed Central

2013-01-01

Background There is large body of knowledge to support the importance of early interventions to improve child health and development. Nonetheless, it is important to identify cost-effective blends of preventive interventions with adequate coverage and feasible delivery modes. The aim of the Children and Parents in Focus trial is to compare two levels of parenting programme intensity and rate of exposure, with a control condition to address impact and cost-effectiveness of a universally offered evidence-based parenting programme in the Swedish context. Methods/Design The trial has a cluster randomised controlled design comprising three arms: Universal arm (with access to participation in Triple P - Positive Parenting Program, level 2); Universal Plus arm (with access to participation in Triple P - Positive Parenting Program, level 2 as well as level 3, and level 4 group); and Services as Usual arm. The sampling frame is Uppsala municipality in Sweden. Child health centres consecutively recruit parents of children aged 3 to 5 years before their yearly check-ups (during the years 2013–2017). Outcomes will be measured annually. The primary outcome will be children’s behavioural and emotional problems as rated by three informants: fathers, mothers and preschool teachers. The other outcomes will be parents’ behaviour and parents’ general health. Health economic evaluations will analyse cost-effectiveness of the interventions versus care as usual by comparing the costs and consequences in terms of impact on children’s mental health, parent’s mental health and health-related quality of life. Discussion This study addresses the need for comprehensive evaluation of the long-term effects, costs and benefits of early parenting interventions embedded within existing systems. In addition, the study will generate population-based data on the mental health and well-being of preschool aged children in Sweden. Trial registration ISRCTN: ISRCTN16513449. PMID:24131587

Dignity and the ownership and use of body parts.

PubMed

Foster, Charles

2014-10-01

Property-based models of the ownership of body parts are common. They are inadequate. They fail to deal satisfactorily with many important problems, and even when they do work, they rely on ideas that have to be derived from deeper, usually unacknowledged principles. This article proposes that the parent principle is always human dignity, and that one will get more satisfactory answers if one interrogates the older, wiser parent instead of the younger, callow offspring. But human dignity has a credibility problem. It is often seen as hopelessly amorphous or incurably theological. These accusations are often just. But a more thorough exegesis exculpates dignity and gives it its proper place at the fountainhead of bioethics. Dignity is objective human thriving. Thriving considerations can and should be applied to dead people as well as live ones. To use dignity properly, the unit of bioethical analysis needs to be the whole transaction rather than (for instance) the doctor-patient relationship. The dignity interests of all the stakeholders are assessed in a sort of utilitarianism. Its use in relation to body part ownership is demonstrated. Article 8(1) of the European Convention of Human Rights endorses and mandates this approach.

From mid-Ordovician ∼470 Myr-old limestone >100 fossil L-chondritic meteorites have been recovered, representing the markedly enhanced flux of meteorites to Earth following the breakup of the L-chondrite parent body. Recently one anomalous meteorite, Österplana 065 (Öst 65), was found in the same beds that yield L chondrites. The cosmic-ray exposure age of Öst 65 shows that it may be a fragment of the impactor that broke up the L-chondrite parent body. Here we show that in a chromium versus oxygen-isotope plot Öst 65 falls outside all fields encompassing the known meteorite types. This may be the first documented example of an ‘extinct' meteorite, that is, a meteorite type that does not fall on Earth today because its parent body has been consumed by collisions. The meteorites found on Earth today apparently do not give a full representation of the kind of bodies in the asteroid belt ∼500 Myr ago. PMID:27299793

Obesity may cluster in families due to shared physical and social environments. This study aims to identify family typologies of obesity risk based on family environments. Using 2007-2008 data from 706 parent/youth dyads in Minnesota, we applied latent profile analysis and general linear models to evaluate associations between family typologies and body mass index (BMI) of youth and parents. Three typologies described most families with 18.8% "Unenriched/Obesogenic," 16.9% "Risky Consumer," and 64.3% "Healthy Consumer/Salutogenic." After adjustment for demographic and socioeconomic factors, parent BMI and youth BMI Z-scores were higher in unenriched/obesogenic families (BMI difference = 2.7, p < 0.01 and BMI Z-score difference = 0.51, p < 0.01, respectively) relative to the healthy consumer/salutogenic typology. In contrast, parent BMI and youth BMI Z-scores were similar in the risky consumer families relative to those in healthy consumer/salutogenic type. We can identify family types differing in obesity risks with implications for public health interventions.

The purpose of the study was to evaluate a parent involvement intervention for childhood obesity intended to increase parents' skills in managing children's weight-related behavior and to improve child-parent relationships. Many studies reported on parental influence on childhood obesity, emphasizing parent involvement in prevention and management of childhood obesity. A randomized controlled trial was conducted. Forty-two parents of overweight/obese children were recruited from four cities and randomized to the experimental group or control group. The parental intervention was provided only to parents in the experimental group and consisted of weekly newsletters and text messages for a period of 5 weeks. Exercise classes and nutrition education were provided to all children. Lifestyle Behaviour Checklist and the Child-Parent Relationship Scale (CPRS) were used for measurement of parent outcome. For the child outcome, dietary self-efficacy, exercise frequency, and body mass index were measured. A mixed-design analysis of variance was performed with city location entered as a random effect. After the intervention, CPRS of parents and dietary self-efficacy of children showed an increase in the experimental group (p < .05). Intervention effects differed significantly according to the city location regarding the control efficacy of parents and dietary self-efficacy of children (p < .05). The results support the effectiveness of the parent involvement intervention in promoting child-parent relationship and dietary self-efficacy of children. However, a 5-week parent involvement intervention was not sufficient to produce significant changes in children's body mass index. Further research is needed to investigate effects of parent involvement intervention with long-term evaluation. Copyright © 2016. Published by Elsevier B.V.

To examine associations between weight status and multiple indicators of family circumstance in Australian elementary school children. Data were combined from the 2001 Children's Leisure Activities Study (CLAS Study) and 2002/3 Health, Eating and Play Study (HEAP Study), involving 2520 children in Grades Prep (mean age 6 years) and 5-6 (mean age 11 years) in Melbourne, Australia. Children's body mass index (BMI) was calculated from measured height and weight. Weight status (non-overweight or overweight) was determined according to International Obesity Taskforce cut-off points and BMI was transformed to z-scores based on the 2000 US growth chart data. Parents reported family circumstance (number of parents in the home, marital status, presence of siblings, parental education, parental employment status, parental work hours [HEAP Study only]) and parental BMI. Regression analyses were conducted for the sample overall and separately for young girls, young boys, older girls and older boys. Children in single-parent homes, those without siblings, and those with less educated mothers and fathers tended to have higher z-BMIs (p=0.002, p=0.003, p<0.001 and p<0.001, respectively) and were more likely to be overweight (p=0.003, p<0.001, p<0.001 and p=0.02, respectively). Associations were stronger for older children. Parental employment and work hours were not consistently associated with child weight status. The multivariable models did not demonstrate a cumulative explanatory effect (R(2)=0.02), except when maternal BMI was included (R(2)=0.07). Individual measures of family circumstance were differentially associated with child weight status and appeared to be largely independent of other measures of family circumstance. Childhood overweight interventions may need to be tailored based on the age, gender, maternal BMI and family circumstances of the target group.

Colour also matters for nocturnal birds: owlet bill coloration advertises quality and influences parental feeding behaviour in little owls.

Chromatic signals of offspring quality have been shown to play a role in parent-offspring communication in diurnal birds, but are assumed to be useless in dim light conditions because colour-based discrimination probably requires more light. A major ecological and evolutionary conundrum in this scenario is why the nestlings of some nocturnal owls display colourful beaks. Here, we test the hypothesis that yellow bill coloration of owlets of the nocturnal little owl Athene noctua may function as a chromatic signal revealing to parents aspects of quality of their offspring. In a first step, we examined physical variation in bill coloration and its covariation with owlet quality. Secondly, we studied parental provisioning in relation to an experimental manipulation of bill coloration of owlets. Bills of owlets showed higher within-nest variation in yellow-red chroma than in brightness. Plasma carotenoid concentration and nestling immunological status were not associated with chromatic or achromatic features of the bill. Interestingly, however, heavier owlets displayed more yellow bills than lighter ones. The effect of bill coloration on parental favouritism changed with brood size. Parents holding large broods preferentially fed owlets with enhanced over reduced yellow bill coloration, whereas those with small broods did not significantly bias feeding in relation to owlet bill coloration. Our results, based on integration of objective spectrophotometric assessment of colour and experimental procedures, confirm that parent little owls use bill coloration to reveal information on owlet body mass to adjust their feeding strategies, thus highlighting the importance of considering potential chromatic signals for a full comprehension of parent-offspring communication processes in nocturnal bird species.

Elephant Moraine 96029, a very mildly aqueously altered and heated CM carbonaceous chondrite: Implications for the drivers of parent body processing

Lee, Martin R.; Lindgren, Paula; King, Ashley J.; Greenwood, Richard C.; Franchi, Ian A.; Sparkes, Robert

2016-08-01

Elephant Moraine (EET) 96029 is a CM carbonaceous chondrite regolith breccia with evidence for unusually mild aqueous alteration, a later phase of heating and terrestrial weathering. The presence of phyllosilicates and carbonates within chondrules and the fine-grained matrix indicates that this meteorite was aqueously altered in its parent body. Features showing that water-mediated processing was arrested at a very early stage include a matrix with a low magnesium/iron ratio, chondrules whose mesostasis contains glass and/or quench crystallites, and a gehlenite-bearing calcium- and aluminium-rich inclusion. EET 96029 is also rich in Fe,Ni metal relative to other CM chondrites, and more was present prior to its partial replacement by goethite during Antarctic weathering. In combination, these properties indicate that EET 96029 is one of the least aqueously altered CMs yet described (CM2.7) and so provides new insights into the original composition of its parent body. Following aqueous alteration, and whilst still in the parent body regolith, the meteorite was heated to ∼400-600 °C by impacts or solar radiation. Heating led to the amorphisation and dehydroxylation of serpentine, replacement of tochilinite by magnetite, loss of sulphur from the matrix, and modification to the structure of organic matter that includes organic nanoglobules. Significant differences between samples in oxygen isotope compositions, and water/hydroxyl contents, suggests that the meteorite contains lithologies that have undergone different intensities of heating. EET 96029 may be more representative of the true nature of parent body regoliths than many other CM meteorites, and as such can help interpret results from the forthcoming missions to study and return samples from C-complex asteroids.

Combating weight-based bullying in schools: is there public support for the use of litigation?

Puhl, Rebecca; Luedicke, Joerg; King, Kelly M

2015-06-01

Bullying litigation is an emerging area of law that has increased in response to serious cases of bullying at school. Weight-based bullying is prevalent at school, but no research has examined the use of litigation to address this problem. We assessed public support for litigation approaches to address weight-based bullying at school, and whether support for litigation varies according to the reason why a student is bullied. A national sample of 994 adults (49% parents) completed an online questionnaire assessing their support for litigation approaches in response to hypothetical incidents of youth bullying. As many as two thirds of participants supported litigation against schools for failing to intervene and protect students from weight-based bullying. Litigation remedies received slightly higher support in response to bullying due to race or sexual orientation compared to body weight. Participants favored litigation approaches that target schools for inadequate intervention or a bully's parents on behalf of their child's actions. Our study offers novel findings about public and parental views of litigation as a potential approach to address weight-based (and other forms of) bullying, and introduces considerations about the potential role of litigation as part of broader remedies to address youth bullying. © 2015, American School Health Association.

Successful childhood obesity intervention models that build sustainable behavioral change are needed, particularly in low-income, ethnic minority communities disparately affected by this problem. Families were referred to Taking Steps Together (TST) by their primary care provider if at least one child had a body mass index ≥85%. The TST intervention comprised 16 weekly 2-hour classes including educational activities, group cooking/eating, and physical activities for parents and children. TST's approach emphasized building self-efficacy, targeting both children and parents for healthy change, and fostering intrinsic motivation for healthier living. Pre-post intervention data were collected on health-related behaviors using a survey, and trained staff measured weight and height. Adults (n = 33) and children (n = 62) were largely Hispanic/Latino and low-income. Adults and children significantly increased their fruit and vegetable consumption and weekly physical activity, and adults significantly decreased sugared beverage consumption and screen time. No change in body mass index was observed for adults or children. This family-focused childhood obesity intervention integrated evidence-based principles with a nonprescriptive approach and produced significant improvements in key healthy behaviors for both adults and children. © 2014 Society for Public Health Education.

Thin-sectioning and analysis of fine-grained meteoritic materials

1992-01-01

The overall theme of the work was the identification of the sources and formation/aggregation mechanisms of the various classes of interplanetary dust particles (IDP's) and to clarify the relationship between IDP's and conventional meteorites. IDP's are believed to be derived from a much broader range of parent bodies than conventional meteorites. Some of these parent bodies (e.g., comets) have escaped that post accretional processing that has affected the parent bodies of meteorites. Therefore, IDP's are likely to preserve a record of early solar system and possibly presolar grain forming reactions. Using analytical electron microscopy (AEM) and more recently micro-infrared (IR) microspectroscopy to examine ultramicrotomed thin sections, we have addressed the questions of IDP formation mechanisms, sources, and their relationship to conventional meteorites. The following sections describe specific findings resulting from these studies.

The Case against Mercury as the Angrite Parent Body (APB)

NASA Technical Reports Server (NTRS)

Hutson, M. L.; Ruzicka, A. M.; Mittlefehldt, D. W.

2007-01-01

Angrites are not plausibly from Mercury based on their high FeO contents and ancient ages (e.g., [1]). Rather, the early crystallization ages of angrites argues for a small asteroidal-sized parent body for these meteorites (e.g., [2]). Despite this, recently it has been proposed that Mercury is the APB [3, 4, 5, 6]. Preserved corona and symplectite textures and the presence of 120 triple junctions in NWA 2999 have been cited as requiring a planetary origin [3, 4], with the symplectites in NWA 2999 resulting from rapid decompression during uplift via thrust faults on Mercury [4], and the coronas during subsequent cooling at low pressure. Glasses along grain boundaries and exsolution lamellae possibly indicative of rapid melting and cooling in NWA 4950 are cited as evidence of rapid decompression [6]. To explain the discrepancy between spectral observations of the Mercurian surface and the high FeO contents in angrites, an early (4.5 Ga), collisionally-stripped FeO-rich basaltic surface has been suggested for Mercury [5, 6].

American Indian children have high rates of overweight and obesity, which may be partially attributable to screen-time behavior. Young children's screen-time behavior is strongly influenced by their environment and their parents' behavior. We explored whether parental television watching time, parental perceptions of children's screen time, and media-related resources in the home are related to screen time (ie, television, DVD/video, video game, and computer use) among Oglala Lakota youth residing on or near the Pine Ridge Reservation in South Dakota. We collected baseline data from 431 child and parent/caregiver pairs who participated in Bright Start, a group-randomized, controlled, school-based obesity prevention trial to reduce excess weight gain. Controlling for demographic characteristics, we used linear regression analysis to assess associations between children's screen time and parental television watching time, parental perceptions of children's screen time, and availability of media-related household resources. The most parsimonious model for explaining child screen time included the children's sex, parental body mass index, parental television watching time, how often the child watched television after school or in the evening, parental perception that the child spent too much time playing video games, how often the parent limited the child's television time, and the presence of a VCR/DVD player or video game player in the home (F(7,367) = 14.67; P < .001; adjusted R(2) = .37). The presence of a television in the bedroom did not contribute significantly to the model. Changes in parental television watching time, parental influence over children's screen-time behavior, and availability of media-related resources in the home could decrease screen time and may be used as a strategy for reducing overweight and obesity in American Indian children.

Common medical terms defined by parents: are we speaking the same language?

2004-11-01

Physicians often assume that a patient understands frequently utilized medical words and patient management may be based on these assumptions. The objective of this study was to determine the public's definition of regularly used medical terminology. A cross-sectional convenience survey was conducted for guardians of children presenting to an urban pediatric emergency department. The orally completed, open-ended questionnaire included parental demographic information and their definition of eleven commonly used medical terms. The words chosen represent common chief complaints given in our emergency department. Definitions were grouped, and a concordance rate of 75% was chosen to consider responses similar. One hundred twenty-two guardians completed the survey (89% parents, 88% female, and 55% high school graduates). Caregivers agreed on the definitions of diarrhea, constipation, dehydration, fever, and seizure. However, diarrhea and constipation were mainly defined by either stool consistency or frequency, not both. Dehydration was appropriately defined as lack of body fluids (92%), but many parents had difficulty identifying more than one sign of dehydration. Fever was thought to be an elevated body temperature (76%), yet 69% felt that a temperature less than 100.5 degrees F was considered a fever. Most respondents did not know the definitions of meningitis (70%), lethargy (64%), and virus (40%). Although commonly used in everyday conversation, there seems to be a large disparity between a caregiver's perception and the actual definition of medical terms. More precise communication may help both parties to understand the true situation.

Parenting styles and body mass index: a systematic review of prospective studies among children.

Parenting style may be an important determinant of an individual's future weight status. However, reviews that evaluate the relationship between parenting style and weight-related outcomes have not focused on prospective studies. We systematically searched PubMed, Embase and PsychInfo for studies published between 1995 and 2016 that evaluated the prospective relationship between parenting style experienced in childhood and subsequent weight outcomes. We identified 11 prospective cohort studies. Among the eight studies that categorized parenting style into distinct groups (i.e. authoritative, authoritarian, permissive and neglectful), five provided evidence that authoritative parenting was associated with lower body mass index gains. Among the six highest quality studies, four suggested a protective role of authoritative parenting style against adverse weight-related outcomes. However, only one study controlled for a comprehensive set of confounders, and the small number of studies conducted within certain age groups precluded our ability to ascertain critical periods when parenting style is most strongly related to child weight. The present literature supports the idea that authoritative parenting may be protective against later overweight and obesity, although findings are mixed. More prospective cohort studies of longer durations, with more sophisticated methods that examine age-varying relationships, and that control for a comprehensive set of confounders, are needed. © 2017 World Obesity Federation.

A Dynamic Cycle of Familial Mental Illness.

Murphy, Gillian; Peters, Kathleen; Wilkes, Lesley; Jackson, Debra

2014-12-01

In this paper, we present A Dynamic Cycle of Familial Mental Illness; an innovative framework, which considers family members' experiences and responses to mental illness. There is an acknowledged discourse noting parental experiences of mental illness alongside a growing body of knowledge acknowledging children's needs while living with parental mental illness. However, there is a paucity of literature that makes reference to the concept of familial mental illness and the cyclic interface of parental and child distress and symptoms. The model is supported by published research studies from several differing disciplines to demonstrate the relationship between parent and child experiences and to synthesise the published short- and longer-term possible impact of familial mental illness. An extensive search of the literature using recognised search engines, keywords and phrases has been undertaken, to generate an appropriate literature base for this work. This literature demonstrates how a child's possible emotional distancing as a response to parental mental illness could increase parental distress. A Dynamic Cycle of Familial Mental Illness adopts the underpinning philosophy of a Stress Vulnerability Model of Mental Illness, which assumes that predisposing factors and increased stress for a parent may have possible links to exacerbation of parental mental distress and symptomology. We advocate for further research of familial mental illness, and argue for a family approach to mental health assessment and treatment in mainstream health and social care sectors.

Interpretations of family size distributions: The Datura example

NASA Astrophysics Data System (ADS)

Henych, Tomáš; Holsapple, Keith A.

2018-04-01

Young asteroid families are unique sources of information about fragmentation physics and the structure of their parent bodies, since their physical properties have not changed much since their birth. Families have different properties such as age, size, taxonomy, collision severity and others, and understanding the effect of those properties on our observations of the size-frequency distribution (SFD) of family fragments can give us important insights into the hypervelocity collision processes at scales we cannot achieve in our laboratories. Here we take as an example the very young Datura family, with a small 8-km parent body, and compare its size distribution to other families, with both large and small parent bodies, and created by both catastrophic and cratering formation events. We conclude that most likely explanation for the shallower size distribution compared to larger families is a more pronounced observational bias because of its small size. Its size distribution is perfectly normal when its parent body size is taken into account. We also discuss some other possibilities. In addition, we study another common feature: an offset or "bump" in the distribution occurring for a few of the larger elements. We hypothesize that it can be explained by a newly described regime of cratering, "spall cratering", which controls the majority of impact craters on the surface of small asteroids like Datura.

Although many studies have relied on parental responses concerning children's school-meal participation, few studies have evaluated parental response accuracy. We investigated misclassification of fourth-grade children's participation in school-meal programs based on parental responses relative to administrative daily records using cross-sectional study data collected for 3 school years (2004-05, 2005-06, and 2006-07) for 1,100 fourth-grade children (87% black; 52% girls) from 18 schools total in one district. Parents reported children's usual school-meal participation on paper consent forms. The district provided administrative daily records of individual children's school-meal participation. Researchers measured children's weight and height. "Usual participation" in breakfast/lunch was defined as ≥50% of days. Parental responses misclassified 16.3%, 12.8%, 19.8%, and 4.7% of children for participation in breakfast, classroom breakfast, cafeteria breakfast, and lunch, respectively. Parental responses misclassified more children for participation in cafeteria than classroom breakfast (P=0.0008); usual-participant misclassification probabilities were less than nonusual-participant misclassification probabilities for classroom breakfast, cafeteria breakfast, and lunch (P<0.0001 for each) (two-proportion z tests). Parental responses concerning children's participation were more accurate for lunch than breakfast; parents overstated breakfast participation (both classroom and cafeteria) and lunch participation. Breakfast participation misclassification was not related to body mass index (P=0.41), sex (P=0.40), age (P=0.63), or socioeconomic status (P=0.21) (multicategory logistic regression controlling for school year, breakfast location, and school). Relying on parental responses concerning children's school-meal participation may hamper researchers' abilities to detect relationships that have policy implications for the child nutrition community.

Although many studies have relied on parental responses concerning children’s school-meal participation, few studies have evaluated parental response accuracy. This article’s analyses investigated misclassification of fourth-grade children’s participation in school-meal programs based on parental responses relative to administrative daily records using cross-sectional study data collected for three school years (2004–05, 2005–06, 2006–07) for 1,100 fourth-grade children (87% Black; 52% girls) from 18 schools total in one district. Parents reported children’s usual school-meal participation on paper consent forms. The district provided administrative daily records of individual children’s school-meal participation. Researchers measured children’s weight and height. “Usual participation” in breakfast/lunch was defined as ≥50% of days. Parental responses misclassified 16.3%, 12.8%, 19.8%, and 4.7% of children for participation in breakfast, classroom breakfast, cafeteria breakfast, and lunch, respectively. Parental responses misclassified more children for participation in cafeteria than classroom breakfast (P=0.0008); usual-participant misclassification probabilities were less than non-usual-participant misclassification probabilities for classroom breakfast, cafeteria breakfast, and lunch (P<0.0001 for each) [two-proportion z-tests]. Parental responses concerning children’s participation were more accurate for lunch than breakfast; parents overstated breakfast participation (both classroom and cafeteria) and lunch participation. Breakfast participation misclassification was not related to body mass index (P=0.41), sex (P=0.40), age (P=0.63), or socioeconomic status (P=0.21) [multi-category logistic regression controlling for school year, breakfast location, and school]. Relying on parental responses concerning children’s school-meal participation may hamper researchers’ abilities to detect relationships that have policy implications for the child nutrition community. The use of administrative daily records of children’s school-meal participation is recommended. PMID:24973169

A growing body of literature suggests that parents socialize early-emerging prosocial behavior across varied contexts and in subtle yet powerful ways. We focus on discourse about emotions and mental states as one potential socialization mechanism given its conceptual relevance to prosocial behavior and its known positive relations with emotion understanding and social-cognitive development, as well as parents' frequent use of such discourse beginning in infancy. Specifically, we ask how parents' emotion and mental state talk (EMST) with their toddlers relates to toddlers' helping and how these associations vary by context. Children aged 18- to 30-months (n = 38) interacted with a parent during book reading and joint play with toys, two everyday contexts that afford parental discussion of emotions and mental states. Children also participated in instrumental and empathic helping tasks. Results revealed that although parents discuss mental states with their children in both contexts, the nature of their talk differs: during book reading parents labeled emotions and mental states significantly more often than during joint play, especially simple affect words (e.g., happy, sad) and explanations or elaborations of emotions; whereas they used more desire talk and mental state words (e.g., think, know) in joint play. Parents' emotion and mental state discourse related to children's empathic, emotion-based helping behavior; however, it did not relate to instrumental, action-based helping. Moreover, relations between parent talk and empathic helping varied by context: children who helped more quickly had parents who labeled emotion and mental states more often during joint play and who elicited this talk more often during book reading. As EMST both varies between contexts and exhibits context-specific associations with empathic prosocial behavior early in development, we conclude that such discourse may be a key form of socialization in emerging prosociality.

The objective of this study was to provide recent temporal trends in parent-reported physical activity in children (6-11 years) between 2009 and 2014. Data from the 2009 to 2014 National Health and Nutrition Examination Survey were used. The analytic sample included 3946 children. Parent proxy of child physical activity at each of the 3 2-year cycles was assessed. For the entire sample, there was a quadratic trend, with the number of days children engaged in at least 60 min/d of physical activity increasing in the period 2011 to 2012 (6.12 days) when compared with the period 2009 to 2010 (5.96 days) and then decreasing in the period 2013 to 2014 (5.83 days). A similar quadratic trend was evident for boys, those above the poverty level, non-Hispanic whites (particularly boys), and those with less than the 85th body mass index-for-age percentile based on sex. A negative linear trend was observed for those above the poverty level and non-Hispanic whites (particularly girls). In conclusion, these findings provide suggestive evidence that over the past 6 years (1999-2014), parents report that children's physical activity has slightly decreased in the latest years, with this observation being most pronounced in boys, those above the poverty level, non-Hispanic whites, and those with less than the 85th body mass index-for-age and sex percentile. Encouragingly, however, across all evaluated subpopulations, most children (55%-82%), as determined by their parents, engaged in 60 min/d of physical activity (consistent with government recommendations).

To explore the relations of parent-child cardiometabolic risk factors and assess the influence of adiposity on these associations. Associations of adiposity, blood pressure (BP), lipids, fasting insulin and glucose, and a risk factor cluster score (CS) were evaluated in a cross-sectional study of 179 parents and their children (6-18 years, N = 255). Insulin resistance was assessed by euglycemic clamp in parents and children aged 10 years or older. Metabolic syndrome in parents was defined by National Cholesterol Education Program's Adult Treatment Panel III criteria. CSs of the risk factors were created based on age-specific z-scores. Analyses included Pearson correlation and linear regression, adjusted for parent and child age, sex, race, and body mass index (BMI), accounting for within-family correlation. We found positive parent-child correlations for measures of adiposity (BMI, BMI percentile, waist, subcutaneous fat, and visceral fat; r = 0.22-0.34, all P ≤ .003), systolic BP (r = 0.20, P = .002), total cholesterol (r = 0.39, P < .001), low-density lipoprotein cholesterol (r = 0.34, P < .001), high density lipoprotein cholesterol (r = 0.26, P < .001), triglycerides (r = 0.19, P = .01), and insulin sensitivity (r = 0.22, P = .02) as well as CSs (r = 0.15, P = .02). After adjustment for BMI all parent-child correlations, except systolic BP, remained significant. Although adiposity is strongly correlated between parents and children, many cardiometabolic risk factors correlate independent of parent and child BMI. Adverse parental cardiometabolic profiles may identify at-risk children independent of the child's adiposity status. Copyright © 2015 Elsevier Inc. All rights reserved.

Introduction Lifestyle Triple P is a general parenting intervention which focuses on preventing further excessive weight gain in overweight and obese children. The objective of the current study was to assess the effectiveness of the Lifestyle Triple P intervention in the Netherlands. Method We used a parallel randomized controlled design to test the effectiveness of the intervention. In total, 86 child-parent triads (children 4–8 years old, overweight or obese) were recruited and randomly assigned (allocation ratio 1:1) to the Lifestyle Triple P intervention or the control condition. Parents in the intervention condition received a 14-week intervention consisting of ten 90-minute group sessions and four individual telephone sessions. Primary outcome measure was the children’s body composition (BMI z-scores, waist circumference and skinfolds). The research assistant who performed the measurements was blinded for group assignment. Secondary outcome measures were the children’s dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, and parental self-efficacy. Outcome measures were assessed at baseline and 4 months (short-term) and 12 months (long-term) after baseline. Multilevel multiple regression analyses were conducted to determine the effect of the intervention on primary and secondary outcome measures. Results No intervention effects were found on children’s body composition. Analyses of secondary outcomes showed positive short-term intervention effects on children’s soft-drink consumption and parental responsibility regarding physical activity, encouragement to eat, psychological control, and efficacy and satisfaction with parenting. Longer-term intervention effects were found on parent’s report of children’s time spent on sedentary behavior and playing outside, parental monitoring food intake, and responsibility regarding nutrition. Conclusion Although the Lifestyle Triple P intervention showed positive effects on some parent reported child behaviors and parenting measures, no effects were visible on children’s body composition or objectively measured physical activity. Several adjustments of the intervention content are recommended, for example including a booster session. Trial Registration Nederlands Trial Register NTR 2555 PMID:25849523

To determine the prevalence of overweight in a sample of urban American Indian adolescents and identify associated behavioral, personal, and socioenvironmental factors. Participants were 246 American Indian boys and girls from the Saint Paul-Minneapolis metropolitan area of Minnesota who completed classroom surveys and anthropometric measurements as part of Project EAT (Eating Among Teens), a population-based study of adolescent nutrition and weight. Survey items assessed behavioral factors (physical activity, television/video viewing, snacking and meal patterns, weight control behaviors), personal factors (body satisfaction, nutrition knowledge, nutrition/fitness attitudes, self-efficacy to make healthy food choices, perceived benefits/barriers to healthy eating), and socioenvironmental factors (family meal routines, family connectedness, parental attitudes regarding nutrition/fitness, availability of household foods, peer attitudes about weight and fitness). Overweight prevalence (body mass index > or =85th percentile) was 43% and 39% for American Indian boys and girls. Compared to nonoverweight American Indian youth, overweight American Indian youth reported watching more hours of television/videos, greater use of weight control behaviors, less frequent snacking, caring less about fitness, lower body satisfaction, and greater parental concern about weight. Obesity prevention programs targeting American Indian adolescents should focus on reducing time spent watching television/videos, screening for unhealthy weight-control behaviors, improving body satisfaction, and providing support for families to integrate healthy eating into their busy lifestyles.

Recent disruption of an asteroid from the Eos family

A key difficulty with searching for partially differentiated asteroids arises from the fact that a crust covers the exterior of the body, and, consequently, should hide the melted interior. This motivates an alternative approach of examining members of asteroid families, i.e., fragments of single large bodies, many of which were in the size regime capable of igneous differentiation, that have been disrupted by catastrophic collisions. Such families could provide a stratigraphic cross section across the interior of the parent asteroid [1]. With more than 10,000 known members, the Eos dynamical family is one of the most numerous and earliest recognized asteroid families [2]. Interestingly, the estimated ˜220-km-diameter parent body [3] is well within the size range capable of differentiation. Thus, existing family members should contain fragments of the deep interior. The Eos family has the highest diversity of taxonomic classes than any other known family [4]. Many members are of K spectral type, which is uncommon outside the family, and is similar to the spectra of CV, CK, CO, and CR carbonaceous chondrites [5]. This diversity leads to the suggestion that the Eos parent body was partially differentiated [4,6]. Thus, the Eos family may not only be a remnant of a partially differentiated parent body, but it could be the source of the CV-CK meteorite group. Here we report the discovery of a young subfamily of the Eos asteroid family. It may help understanding the mineralogical nature of the Eos asteroid family and of its parent body. By applying the hierarchical clustering method [7], we find an extremely compact 16-body cluster within the borders of the Eos family. We name the cluster (6733) 1992 EF, after its largest member. The statistical significance of this new cluster is estimated to be above 99%, indicating that its members share a common origin. All members of the cluster are found to be dynamically stable over long timescales. Backward numerical orbital integrations are used to set an upper limit of the age of the cluster to be only 4 Myr.

We evaluated an attachment theory model in which mother and father care were hypothesized to be indirectly related to body dissatisfaction mediated by attachment anxiety and media internalization. Participants were 232 women diagnosed with an eating disorder who completed a retrospective measure of parental bonds, and measures of attachment anxiety, media internalization, and body image. Mother care was negatively associated with body dissatisfaction, suggesting that recollection of mothers as less caring was directly related to poorer body image. Lower father care, was indirectly associated with greater body dissatisfaction mediated by higher attachment anxiety and higher media internalization. That is, women with an eating disorder who recollected fathers as less caring had higher attachment anxiety, which was related to greater internalizing of media-related thin ideals, that in turn was associated with poorer body image. Mothers and fathers may impact body dissatisfaction by differing mechanisms in clinical samples. Copyright © 2016 Elsevier Ltd. All rights reserved.

Recent findings from our research indicate that children participating in a creative afterschool program exhibit overall healthier lifestyle practices compared to the average US pediatric population. This observation led us to investigate the prevalence of overweight/obesity and lifestyle practices of their parents. To determine the strongest predictors of weight status for female parents whose children were participating in such creative afterschool program. Surveyed subjects were parents of children who competed in the 2008 and 2009 Destination ImagiNation(®) Global Finals in Knoxville, Tennessee. A total of 4,608 children participated in data collection, with parental consent. For the combined 2 years, 1,118 parents, 87% of whom were females (n=1,032) completed online questionnaires, which were based on the Behavioral Risk Factor Surveillance System and included self-reported height, weight, dietary intake, physical activity, and socioeconomic status. The majority of this population was white, and less than 5% were African American or Hispanic. We report here results obtained for the female parents. Only 45.2% of these female parents were overweight/obese, compared to a national average of 64.1% reported by the National Health Nutrition Examination Surveys for 2007-2008. Furthermore, this population was significantly more physically active compared to national average. Most parents (76%) had completed a college degree and reported high incomes. Parents with the lowest income were the most obese in this population. Finally, we found a significant association between parent and child weight status. These studies demonstrate that female parents of children who have healthy lifestyles were physically active, which likely accounts for the parents' lower overweight/obesity rates. In addition to physical activity, income and percentage of calories from fat were all predictors of weight status.

To address the public health crisis of overweight and obese preschool-age children, the Nutrition And Physical Activity Self Assessment for Child Care (NAP SACC) intervention was delivered by nurse child care health consultants with the objective of improving child care provider and parent nutrition and physical activity knowledge, center-level nutrition and physical activity policies and practices, and children's body mass index (BMI). A seven-month randomized control trial was conducted in 17 licensed child care centers serving predominantly low income families in California, Connecticut, and North Carolina, including 137 child care providers and 552 families with racially and ethnically diverse children three to five years old. The NAP SACC intervention included educational workshops for child care providers and parents on nutrition and physical activity and consultation visits provided by trained nurse child care health consultants. Demographic characteristics and pre - and post-workshop knowledge surveys were completed by providers and parents. Blinded research assistants reviewed each center's written health and safety policies, observed nutrition and physical activity practices, and measured randomly selected children's nutritional intake, physical activity, and height and weight pre- and post-intervention. Hierarchical linear models and multiple regression models assessed individual- and center-level changes in knowledge, policies, practices and age- and sex-specific standardized body mass index (zBMI), controlling for state, parent education, and poverty level. Results showed significant increases in providers' and parents' knowledge of nutrition and physical activity, center-level improvements in policies, and child-level changes in children's zBMI based on 209 children in the intervention and control centers at both pre- and post-intervention time points. The NAP SACC intervention, as delivered by trained child health professionals such as child care health consultants, increases provider knowledge, improves center policies, and lowers BMI for children in child care centers. More health professionals specifically trained in a nutrition and physical activity intervention in child care are needed to help reverse the obesity epidemic.

The purpose of this study is to determine whether the lifestyle and body stature are significantly associated with the axial length (AL) of the eyes of Japanese third grade students. A prospective, cross sectional, observational study was performed on 122 third grade students consisting of 61 boys and 61 girls ages 8 to 9 years. The AL, body height, body weight, and body mass index (BMI) were measured. The lifestyle was determined by activities such as the daily duration of indoor studying, television viewing, use of computers and smart phones, outdoor activity time, bed time, Japanese or Western dietary habits, and parental myopia were investigated by a questionnaire with three or five grade levels. The relationship between AL and the questionnaire variables were analyzed by Spearman's correlation analyses. Westernized dietary habits (r = -0.24, P = 0.01), duration of computer and smart phone use (r = 0.24, P = 0.008), parental myopia (r = 0.39, P < 0.001), body weight (r = 0.26, P = 0.005), and BMI (r = 0.23, P = 0.011) were significantly correlated with the AL. Multiple logistic regression analyses showed that the sex [r = -0.48; 95% confidence interval (CI) -0.80 to -0.17, P = 0.003], body weight (r = 0.04; 95% CI 0.02 to 0.07, P = 0.038), westernized dietary habits (r = -0.30; 95% CI -0.55 to -0.05, P = 0.021), and parental myopia (r = 0.40; 95% CI 0.20 to 0.61, P < 0.001) were significantly and independently correlated with the AL. The body weight and parental myopia and westernized dietary habits are factors significantly associated with myopia. Changing from Japanese food style to westernized food style might increase the risk of progression of school myopia.

Objective To examine the unique and additive associations of family functioning and parenting practices with adolescent disordered eating behaviors (i.e., dieting, unhealthy weight control behaviors, binge eating). Methods Data from EAT (Eating and Activity in Teens) 2010, a population-based study assessing eating and activity among racially/ethnically and socio-economically diverse adolescents (n = 2,793; mean age = 14.4, SD = 2.0; age range = 11–19) was used. Logistic regression models were used to examine associations between adolescent dieting and disordered eating behaviors and family functioning and parenting variables, including interactions. All analyses controlled for demographics and body mass index. Results Higher family functioning, parent connection, and parental knowledge about child’s whereabouts (e.g. who child is with, what they are doing, where they are at) were significantly associated with lower odds of engaging in dieting and disordered eating behaviors in adolescents, while parent psychological control was associated with greater odds of engaging in dieting and disordered eating behaviors. Although the majority of interactions were non-significant, parental psychological control moderated the protective relationship between family functioning and disordered eating behaviors in adolescent girls. Conclusions Clinicians and health care providers may want to discuss the importance of balancing specific parenting behaviors, such as increasing parent knowledge about child whereabouts while decreasing psychological control in order to enhance the protective relationship between family functioning and disordered eating behaviors in adolescents.

The home food environment is critically important for the development of children’s health-related practices. By managing dietary restrictions, providing nutritional knowledge and demonstrating eating behaviours, parents contribute to children’s food preferences and eating patterns. The present study examined nutritional knowledge, eating habits and appetite traits among 387 Polish five-year-old healthy and overfat boys and girls in the context of parental feeding styles and body-fat status. We observed that girls presented healthier eating habits than boys; however, overfat boys had better nutritional knowledge. Children’s body-fat percentage (%BF) was found to be linked with eating behaviours such as low satiety responsiveness and increased food responsiveness in girls as well as low emotional undereating and increased emotional overeating in boys. Our results revealed that overfat mothers, who were more prone to use the encouragement feeding style, rarely had daughters with increased %BF. Parents of overfat girls, however, were less likely to apply encouragement and instrumental feeding styles. Contrary to popular belief and previous studies, overfat women do not necessarily transmit unhealthy eating patterns to their children. Parents’ greater emphasis on managing the weight and eating habits of daughters (rather than sons) probably results from their awareness of standards of female physical attractiveness.

To identify the sociodemographic characteristics and risk factors associated with suspected foreign bodies in the ear, nose, throat, airway, and esophagus among Polish children. Case series with chart review. Setting Tertiary care medical center. A retrospective analysis of the medical records of patients hospitalized for a suspected foreign body (FB) between 1998 and 2008 was conducted. Data regarding place of residence, presence of siblings, parents' educational status, seasonality, psychomotor development, age, and sex were collected and statistically analyzed. Of the 1011 patients with suspected foreign body insertion, 849 (84%) had a positive diagnosis. Of the confirmed foreign bodies, 96 were found in the tracheobronchial tree, 142 were found in the esophagus, and 611 were located in the external auditory canals, nasopharyngeal passage, tonsils, auricles, or lips. Sociodemographically, 596 of the children came from urban areas, with a preponderance of males (55%). Objects were removed more frequently in summer and autumn (60%). Children with siblings (53%) predominated. The majority of patients (52%) had parents with an elementary education. Food was the most frequent foreign body in children under 3 years of age. Patients with delayed psychomotor development constituted 1.6% of the analyzed population. Being male, 1 to 3 years of age, belonging to an urban family with siblings, and having parents with an elementary education increased the risk of foreign body insertion. Training caregivers about proper nutrition and safety rules when playing with children can reduce the risk of accidents related to foreign body insertion.

Amino acids in the Tagish Lake Meteorite

High-performance liquid chromatography (HPLC) based amino acid analysis of a Tagish Lake meteorite sample recovered 3 months after the meteorite fell to Earth have revealed that the amino acid composition of Tagish Lake is strikingly different from that of the CM and CI carbonaceous chondrites. We found that the Tagish Lake meteorite contains only trace levels of amino acids (total abundance = 880 ppb), which is much lower than the total abundance of amino acids in the CI Orgueil (4100 ppb) and the CM Murchison (16 900 ppb). Because most of the same amino acids found in the Tagish Lake meteorite are also present in the Tagish Lake ice melt water, we conclude that the amino acids detected in the meteorite are terrestrial contamination. We found that the exposure of a sample of Murchison to cold water lead to a substantial reduction over a period of several weeks in the amount of amino acids that are not strongly bound to the meteorite matrix. However, strongly bound amino acids that are extracted by direct HCl hydrolysis are not affected by the leaching process. Thus even if there had been leaching of amino acids from our Tagish Lake meteorite sample during its 3 month residence in Tagish Lake ice and melt water, a Murchison type abundance of endogenous amino acids in the meteorite would have still been readily detectable. The low amino acid content of Tagish Lake indicates that this meteorite originated fiom a different type of parent body than the CM and CI chondrites. The parent body was apparently devoid of the reagents such as aldehyldes/ketones, HCN and ammonia needed for the effective abiotic synthesis of amino acids. Based on reflectance spectral measurements, Tagish Lake has been associated with P- or D-type asteroids. If the Tagish Lake meteorite was indeed derived fiom these types of parent bodies, our understanding of these primitive asteroids needs to be reevaluated with respect to their potential inventory of biologically important organic compounds.

Self-control problems commonly manifest as temper outbursts and repetitive/rigid/impulsive behaviors, in children with autism spectrum disorders (ASD), which often contributes to learning difficulties and caregiver burden. The present study aims to compare the effect of a traditional Chinese Chan-based mind-body exercise, Nei Yang Gong, with that of the conventional Progressive Muscle Relaxation (PMR) technique in enhancing the self-control of children with ASD. Forty-six age- and IQ-matched ASD children were randomly assigned to receive group training in Nei Yang Gong (experimental group) or PMR (control group) twice per week for four weeks. The participants’ self-control was measured by three neuropsychological tests and parental rating on standardized questionnaires, and the underlying neural mechanism was assessed by the participants’ brain EEG activity during an inhibitory-control task before and after intervention. The results show that the experimental group demonstrated significantly greater improvement in self-control than the control group, which concurs with the parental reports of reduced autistic symptoms and increased control of temper and behaviors. In addition, the experimental group showed enhanced EEG activity in the anterior cingulate cortex, a region that mediates self-control, whereas the PMR group did not. The present findings support the potential application of Chinese Chan-based mind-body exercises as a form of neuropsychological rehabilitation for patients with self-control problems.

Parental feeding practices and sociocultural pressures theoretically influence eating behavior. Yet, whether these factors relate to eating in the absence of hunger (EAH) is unknown. We assessed if sociocultural pressures were associated with EAH among 90 adolescents (Mage = 15.27, SD = 1.39; 48% female). Parents completed the Child Feeding Questionnaire. Adolescents completed the Perceived Sociocultural Pressures Scale, Sociocultural Attitudes Towards Appearance Questionnaire-3, and Multidimensional Body Self-Relations Questionnaire-Appearance Scales. On two occasions, EAH was assessed as snack food intake after adolescents ate to satiety. Controlling for body composition and demographics, parental restriction and family pressure to be thin were associated with greater EAH. Media pressure was related to more EAH in girls. Appearance orientation and preoccupation with becoming overweight mediated links between sociocultural pressures and EAH. Findings support the notion that sociocultural pressures and their links to body image may contribute to the course of disinhibited eating behaviors during adolescence. PMID:23394966

Howardites, eucrites and diogenites (HED) form a suit of igneous achondrite meteorites that are thought to have formed on a single asteroidal body. While there have been many different models proposed for the formation of the HED parent asteroid they can be generalized into two end member models. One is the magma ocean model (e.g. [1]) in which the entire HED parent body was continuously fractionated from a planet wide magma ocean with diogenites representing the lower crust and eucrites being upper crustal rocks. The second model hypothesizes that diogenites and eucrites were formed as a series of intrusions and/or extrusions of partial melts of a primitive proto-Vesta [2]. We use in situ trace element analysis together with major and minor element analysis to try and distinguish between these different hypotheses for the evolution of the HED parent body.

Chondritic Meteorites: Nebular and Parent-Body Formation Process

Rubin, Alan E.

1997-01-01

Chondritic meteorites are the products of condensation, agglomeration and accretion of material in the solar nebula; these objects are the best sources of information regarding processes occurring during the early history of the solar system. We obtain large amounts of high-quality chemical and petrographic data and use them to infer chemical fractionation processes that occurred in the solar nebula and on meteorite parent bodies during thermal metamorphism, shock metamorphism and aqueous alteration. We compare diverse groups of chondrites and model their different properties in terms of processes that differed at different nebular locations or on different parent-bodies. In order to expand our set of geochemically important elements (particularly Si, C, P and S) and to distinguish the different oxidation states of Fe, Greg Kallemeyn spent three months (1 Sept. - 30 Nov. 1995) at the Smithsonian Institution to learn Eugene Jarosewich's wet chemical techniques. Key specimens from the recently established CK, CR and R chondrite groups were analyzed.

The aim of this study was to elucidate the effect of the personal characteristics and psychological status of parents on their children's Body Mass Index (BMI) by using validated questionnaires. Obese and healthy control group was assessed with The Parental Attitude Research Instrument (PARI) for the evaluation of parental attitudes towards their children. Additionally, Depression Anxiety and Stress Scale (DASS) were used to assess the relationships between parental depression, anxiety, stress and childhood obesity. A total of 105 children and their parents were divided into two groups. The study group consisted of 58 children with a BMI of higher than 85th percentile whereas 47 children with normal BMI (<85th percentile) were included as the control group. In both groups, the BMI of mothers which is between 25-and 30 kg/m2 and >30 kg/m2 had significant impact on the risk of children's obesity status 1.12-fold and 3.68-fold respectively. The PARI results provided that the children who had disciplined, over-protective parents and those in the parental incompatibility group had higher risk of being obese. Analysis of the DASS Test results showed that children having depressed parents had significantly higher risk of obesity than children whose parents were not depressed (P<0.05). Our results provided that, the parent's status such as obesity, depression and strict personal behaviors have negative impact on their children's weight which is resulting with obesity.

Our objective was to investigate the association between parenting style and eating disorder symptoms in patients treated in an intensive outpatient center for eating disorders. The study design is a cross-sectional survey set in a community-based facility for eating disorders. Participants included 53 families, including 32 with a child meeting the DSM-IV criteria for anorexia nervosa, 18 for bulimia nervosa, and 3 diagnosed ED-NOS. Data was collected using the Parental Authority Questionnaire (PAQ), the Eating Disorders Inventory-2 (EDI-2) and the Eating Attitudes Test (EAT-26). Significant, negative correlations were found between drive for thinness scores and body dissatisfaction scores and the patient's perception of the father as authoritative. Total patient EDI score was significantly and positively correlated with patient's perception of the father as authoritarian and inversely correlated with her perception of him as authoritative. These results emphasize the importance of fathers' role in the eating disorder pathology, a relatively untapped area of research.

Objectives. We examined how Hispanic parents' income and education, combined with their nativity status, influenced the body mass index (BMI) of their children, compared with non-Hispanic White children and their parents. Methods. We used data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 to estimate linear growth curve models of children's initial BMI in kindergarten and change in BMI through fifth grade. Socioeconomic status was measured by logged household income and parental educational attainment (less than high school, high school graduate, some college, college graduate or higher). Results. Parental education was negatively associated with children's BMI (baseline and growth) for non-Hispanic White children. Among Hispanic children, the association of parental education with growth in BMI was negative but much weaker. The weak effect of parental education was not explained by the presence of immigrants in the Hispanic population. Income was strongly negatively associated with children's BMI in kindergarten among children of Hispanic and White natives, but positively associated among Hispanic immigrant families. Conclusions. The positive income–BMI association among Hispanic immigrant children might reflect cultural differences that immigrant parents carry with them from their countries of origin. PMID:19846690

Childhood obesity is a health hazard increasing worldwide. Preschool period which is under supervision of parents is a critical period to detect overweight and take precautions. We studied the factors affecting parental estimation of their preschool child's weight. Three hundred sixty seven mothers completed questionnaires consisting of child's and parents' anthropometric measurements, parents' assessment of their child's and their own weight status, and general information about their lifestyle. Mothers also chose their wish for current and future body image of their child from child drawings representing percentiles. Child body mass index-for-age z score (BAZ) was related to birth weight and child's appetite. BAZ was not related to child's gender, presence of chronic disease, family pattern, parental age, education or income. 43.1 % of mothers correctly assessed child's BAZ verbally. Maternal verbal estimation was correlated with maternal visual estimation, paternal verbal estimation and child's BAZ. Mothers' wish for future figure of the child was not related to child's BAZ, but showed correlation with mothers' wish for current figure of the child. Mother's correct perception of her child's weight was found to be high, consistent with her spouse and related to child's BAZ.

Background Recent findings from our research indicate that children participating in a creative afterschool program exhibit overall healthier lifestyle practices compared to the average US pediatric population. This observation led us to investigate the prevalence of overweight/obesity and lifestyle practices of their parents. Objective To determine the strongest predictors of weight status for female parents whose children were participating in such creative afterschool program. Design Surveyed subjects were parents of children who competed in the 2008 and 2009 Destination ImagiNation® Global Finals in Knoxville, Tennessee. A total of 4,608 children participated in data collection, with parental consent. For the combined 2 years, 1,118 parents, 87% of whom were females (n=1,032) completed online questionnaires, which were based on the Behavioral Risk Factor Surveillance System and included self-reported height, weight, dietary intake, physical activity, and socioeconomic status. The majority of this population was white, and less than 5% were African American or Hispanic. Results We report here results obtained for the female parents. Only 45.2% of these female parents were overweight/obese, compared to a national average of 64.1% reported by the National Health Nutrition Examination Surveys for 2007—2008. Furthermore, this population was significantly more physically active compared to national average. Most parents (76%) had completed a college degree and reported high incomes. Parents with the lowest income were the most obese in this population. Finally, we found a significant association between parent and child weight status. Conclusions These studies demonstrate that female parents of children who have healthy lifestyles were physically active, which likely accounts for the parents’ lower overweight/obesity rates. In addition to physical activity, income and percentage of calories from fat were all predictors of weight status. PMID:22912600

To estimate the potential to reduce childhood obesity through targeted interventions of overweight households. Cross-sectional nationally representative samples of the Scottish population. Households in Scotland during 2008 and 2009. A total of 1651 households with parents and children aged 2-15 years. The WHO cut-off points for adult body mass index (BMI): overweight (25 to <30 kg/m2) and obese (≥30 kg/m2). Overweight and obesity in childhood respectively defined as a BMI 85th to <95th percentile and ≥95th percentile based on 1990 reference centiles. Thirty-two percent (600/1849) of children and 75% (966/1290) of adults were overweight or obese. Seventy-five percent (1606/2128) of all children lived with a parent who was overweight or obese. Among obese children, 58% (185/318) lived with an obese parent. The population attributable risk percentage of child obesity associated with parental obesity was 32.5%. Targeting obese households would require substantial falls in adult weight and need to reach 38% of all children; it might achieve a reduction in the prevalence of childhood obesity of 14% in these households (from 26% to 12%). Targeting parents with BMI ≥ 40 might reduce the overall prevalence of child obesity by 9%. Such an intervention would require large weight loss, consistent with approaches used for morbidly obese adults; it would involve 4% of all children and lead to a reduction in the prevalence of obesity in these households from 57% to 16%. Family-based interventions for obesity would be most efficiently targeted at obese children whose parents are morbidly obese.

Background High-quality, Web-based dietary assessment tools for children are needed to reduce cost and improve user-friendliness when studying children’s dietary practices. Objective To evaluate the first Web-based dietary assessment tool for children in Norway, the Web-based Food Record (WebFR), by comparing children’s true school lunch intake with recordings in the WebFR, using direct unobtrusive observation as the reference method. Methods A total of 117 children, 8-9 years, from Bærum, Norway, were recruited from September to December 2013. Children completed 4 days of recordings in the WebFR, with parental assistance, and were observed during school lunch in the same period by 3 observers. Interobserver reliability assessments were satisfactory. Match, omission, and intrusion rates were calculated to assess the quality of the recordings in the WebFR for different food categories, and for all foods combined. Logistic regression analyses were used to investigate whether body mass index (BMI), parental educational level, parental ethnicity or family structure were associated with having a “low match rate” (≤70%). Results Bread and milk were recorded with less bias than spreads, fruits, and vegetables. Mean (SD) for match, omission, and intrusion rates for all foods combined were 73% (27%), 27% (27%), and 19% (26%), respectively. Match rates were statistically significantly associated with parental educational level (low education 52% [32%] versus high 77% [24%], P=.008) and parental ethnicity (non-Norwegian 57% [28%] versus others 75% [26%], P=.04). Only parental ethnicity remained statistically significant in the logistic regression model, showing an adjusted odds ratio of 6.9 and a 95% confidence interval between 1.3 and 36.4. Conclusions Compared with other similar studies, our results indicate that the WebFR is in line with, or better than most of other similar tools, yet enhancements could further improve the WebFR.

Parenting style influences a child's overall diet quality and establishes food preferences. Parenting style and "food rules" for children differ by eating at home or away from home. Eating meals away from home is increasing despite associations with consumption of unhealthy foods and higher weight status. The objective of the current study was to compare parenting practices and decision-making at restaurants versus at home. A mixed methods approach was utilized: facilitated, individual interviews to explore decision-making and parenting practices; written questionnaires for socio-demographic information; and body mass index. Summaries and emergent themes were generated based on examination of tapes and transcripts. Descriptive statistics were computed for questionnaire data. Twenty-five mothers of children of five to eight years who ate at restaurants at least two times per week participated. Mothers reported more permissive food rules at restaurants yet maintained higher behavioral expectations. Mothers were also more likely to make decisions about whether they eat out, where to eat, and children's meal selections than their children. The findings suggest that parenting practices toward overall behavior and food choices may differ at restaurants than at home, highlighting the importance of healthy menu options, further research, and educational strategies.

Objective: To present athletic trainers with recommendations for safe weight loss and weight maintenance practices for athletes and active clients and to provide athletes, clients, coaches, and parents with safe guidelines that will allow athletes and clients to achieve and maintain weight and body composition goals. Background: Unsafe weight management practices can compromise athletic performance and negatively affect health. Athletes and clients often attempt to lose weight by not eating, limiting caloric or specific nutrients from the diet, engaging in pathogenic weight control behaviors, and restricting fluids. These people often respond to pressures of the sport or activity, coaches, peers, or parents by adopting negative body images and unsafe practices to maintain an ideal body composition for the activity. We provide athletic trainers with recommendations for safe weight loss and weight maintenance in sport and exercise. Although safe weight gain is also a concern for athletic trainers and their athletes and clients, that topic is outside the scope of this position statement. Recommendations: Athletic trainers are often the source of nutrition information for athletes and clients; therefore, they must have knowledge of proper nutrition, weight management practices, and methods to change body composition. Body composition assessments should be done in the most scientifically appropriate manner possible. Reasonable and individualized weight and body composition goals should be identified by appropriately trained health care personnel (eg, athletic trainers, registered dietitians, physicians). In keeping with the American Dietetics Association (ADA) preferred nomenclature, this document uses the terms registered dietitian or dietician when referring to a food and nutrition expert who has met the academic and professional requirements specified by the ADA's Commission on Accreditation for Dietetics Education. In some cases, a registered nutritionist may have equivalent credentials and be the commonly used term. All weight management and exercise protocols used to achieve these goals should be safe and based on the most current evidence. Athletes, clients, parents, and coaches should be educated on how to determine safe weight and body composition so that athletes and clients more safely achieve competitive weights that will meet sport and activity requirements while also allowing them to meet their energy and nutritional needs for optimal health and performance.

The prevalence of macrosomia has risen markedly worldwide, including in China, during the past two decades. Few epidemiological studies, however, have investigated the risk factors for macrosomia in China. This study was designed to investigate the associations between parental anthropometric characteristics, gestational weight gain (GWG), and risk of macrosomia in China. This population-based, case-control study in Wuhan, China, included a total of 6341 subjects (870 cases and 5471 controls). Multivariable logistic regression was conducted to calculate odds ratios (OR) and 95% confidence intervals (CI). Mothers or fathers who were overweight or obese before pregnancy had an elevated risk of giving birth to a macrosomic infant compared with their normal weight counterparts. Women with GWG above the Institute of Medicine (IOM) recommendation had an adjusted OR of 6.09 [95% CI 5.04, 7.35] for delivering a macrosomic infant compared with women who had GWG within the IOM recommendation. When stratified by maternal pre-pregnancy body mass index (BMI), women who were underweight or normal weight before pregnancy were observed to have a higher risk of macrosomia birth associated with greater GWG. Parental pre-pregnancy overweight/obesity and excessive GWG during pregnancy were highly associated with macrosomia. The association with GWG was most pronounced in mothers who had a normal or underweight pre-pregnancy BMI. Weight control efforts before pregnancy for mothers and fathers as well as control of maternal gain during pregnancy may reduce the risk of macrosomia. © 2015 John Wiley & Sons Ltd.

Participation in extracurricular activities creates opportunities for children to foster friendships, promote a sense of belonging, and improve physical and mental well-being. The objective of this study was to determine the relationship(s) of personal factors, seizure variables, and social supports with extracurricular participation in children with epilepsy (CWE). Baseline analysis of the QUALITÉ longitudinal study cohort of children aged 8-14 years (N=426) was conducted. Variables hypothesized to be related to the participation of CWE were classified using the International Classification of Functioning, Disability and Health according to body functions (presence of generalized tonic-clonic seizures in the past month, on/off AEDs, and seizure severity), environmental factors (perceived social support from parents and friends), and personal factors (sex, age, family structure, and family income). Analysis of variables related to extracurricular participation was conducted with regression modeling. Personal factors of age, gender, and family structure as well as body function variables of generalized tonic-clonic seizures and seizure severity were found to be the most important to extracurricular participation based on how frequently they were included in the final models (16/16 and 13/16 times, respectively). When parental support was found to be related to participation, the association was negative in 6 out of 16 models. The personal factors that are related to extracurricular participation among children with epilepsy mirror samples based on the general population, although seizures also play an important role. The relationship between perceived parental support and actual participation levels warrants further exploration. Copyright © 2015 Elsevier Inc. All rights reserved.

Brief report: parenting styles and obesity in Mexican American children: a longitudinal study.

PubMed

Olvera, Norma; Power, Thomas G

2010-04-01

To assess longitudinally the relations between four parenting styles (authoritative, authoritarian, uninvolved, and indulgent) and child weight status in Mexican American families. Sixty-nine low-income Mexican American mothers and their 4- to 8-year-old children participated in a 4-year longitudinal study. Mothers completed demographic and parenting measures. Children's body weight and height were assessed annually. Body mass index was calculated to determine weight status. At baseline, 65% of children were found to be normal weight, 14% were overweight, and 21% were obese. Analyses examined how parenting styles at baseline predicted child's weight status 3 years later, controlling for initial weight status. Children of indulgent mothers were more likely to become overweight 3 years later than children of authoritative or authoritarian mothers. This study provides longitudinal evidence for the role of indulgent parenting in predicting overweight in Mexican American children. Possible mediating factors that may account for this relationship (e.g., dietary patterns, physical activity patterns, and children's self-regulation) are considered.

Positive parenting mitigates the effects of poor self-regulation on body mass index trajectories from ages 4-15 years.

2014-08-01

This study sought to determine whether parenting style moderates the effects of delay of gratification on body mass index (BMI) trajectories from ages 4-15 years. Longitudinal data were analyzed for 778 children drawn from the Study of Early Child Care and Youth Development. Parenting style (i.e., authoritative, authoritarian, permissive, and neglectful) was created from measures of mothers' sensitivity and expectations for self-control when children were age 4 years. Self-regulation was also measured at 4 years using a well-known delay of gratification protocol. BMI was calculated from measured height and weight at each time point. Mixed modeling was used to test the interaction of parenting styles and ability to delay gratification on BMI trajectories from 4-15 years. There was a significant interaction effect of parenting and ability to delay on BMI growth from 4-15 years for boys. Boys who had authoritarian mothers and failed to delay gratification had a significantly steeper rate of growth in BMI from childhood through adolescence than children in any other parenting by delay group. Authoritative and permissive parenting styles were protective against more rapid BMI gains for boys who could not delay gratification. Ability to delay gratification was protective against BMI gains for boys who had parents with authoritarian or neglectful parenting styles.

2002-02-01

The purpose of this study was to tes a mediational model of associations between parental overprotectiveness (OP), behavioral autonomy. and psychosocial adjustment in 68 families with 8- and 9-year-old preadolescents with spipa bifida and a demographically matched sample of 68 families with able-bodied children. Measures included questionnaire and observational assessments of parental OP; parent and child reports of behavioral autonomy; and parent, child, and teacher reports of preadolescent adjustment. On the basis of both questionnaire and observational measures of OP, mothers and fathers of children with spina bifida were significantly more overprotective than their counterparts in the able-bodied sample, although this group difference was partially mediated by children's cognitive ability. Across samples, mothers were more likely to be overprotective than fathers. Both questionnaire and observational measures of parental OP were associated with lower levels of preadolescent decision-making autonomy as well as with parents being less willing to grant autonomy to their offspring in the future. For the questionnaire measure of OP, and only for the spina bifida sample. the mediational model was supported such that parental OP was associated with less behavioral autonomy, which was, in turn, associated with more externalizing problems. Findings are discussed in relation to the literature on parenting, autonomy development, and pediatric psychology.

Alteration and formation of rims on the CM parent body

NASA Technical Reports Server (NTRS)

Browning, Lauren B.; Mcsween, Harry Y., Jr.; Zolensky, Michael

1994-01-01

All types of coarse-grained components in CM chondrites are surrounded by fine-grained dust coatings, but the origin of these rims is not yet clear. Although a strictly nebular origin seems likely for rims in the relatively unaltered type 3 chondrites, the rims in CM chondrites are dominated by secondary alteration phases. It has been argued that either the coarse-grained cores accreted altered rim materials while still in the nebula or that alteration of primary rim phases occurred on the CM parent body. To constrain the origin of alteration phases in rim material, we have analyzed the textures and mineral associations from 10 CM chondritic falls by optical and scanning electron microscopy. Our results indicate that the secondary phases in CM chondritic rims were produced by parent body fluid-rock interactions which redefined some primary rim textures and may have produced, in some cases, both coarse-grained components and the rims that surround them. Textural features demonstrate the interactive exchange of alteration fluids between rims, matrix, and chondrules on the CM parent body. For example, most matrix-rim contacts are gradational, suggesting the synchronous alteration of both components. Several observations suggest the possibility of in situ rim production. For example, tochilinite and phyllosilicates commonly form rims around matrix carbonates, which are generally believed to have precipitated from alteration fluids on the CM parent body. This suggests that the rims surrounding matrix carbonates may also have been produced by alteration processes. Partially replaced chondrule olivines bear a striking resemblance to many rimmed olivines in the matrix which suggests, by analogy, that site-specific precipitation of S-bearing phases may also be responsible for the occurrence of many tochilinite-rich rims around isolated matrix olivines. Non-silicate rims precipitate around olivines of any composition, but the process is most effective for fayalitic olivines. Most of the remaining olivines in CM chondrites are relatively Mg-rich, which suggests that the precipitation of S-bearing rims on olivines may not have been an important process in the aqueous alteration of CM chondrites. We conclude that: (1) precursor rim materials in CM chondrites were subjected to pervasive aqueous alteration on the CM parent body; and (2) textures and mineral associations observed in CM chondrites also suggest the possibility of in situ rim production.

Formation of thin sulfide rinds on the CM parent body. [Abstract only

NASA Technical Reports Server (NTRS)

Browning, L. B.; Mcsween, H. Y., Jr.; Zolensky, M.

1994-01-01

Many of the textures that are observed in CM chondrites have been alternately assigned nebular, parent-body, or combined nebular-parent body origins. Since it is very difficult to substantiate the production of complex textures in the nebula, an alternate approach to this problem is to rigorously determine which of the observable textures could have been produced by reasonable aqueous alteration processes on the CM parent body. Potential parent body reactions involving S deserve special attention because S-bearing phase define many important CM textures, such as rims. We have examined the possibility that the thin (about 5 microns) rinds of sulfides observed around some partially dissolved olivines within the chondrules and matrixes of CM chondrites were formed by the preferential precipitation of sulfides at or near dissolving olivine boundaries during parent-body alteration. Our model defines two infinite and parallel planes of olivine that are separated by pure water. Average separation distances between olivine grains in CM chondrites at the time of accretion (about 100-200 microns) were estimated by assuming a closed system fluid/rock ratio of 45% and varying the bimodal grain-size distribution. We restrict our calculations to the case of an isochemical system with sufficient bisulfide in solution to account for precipitation of pyrrhotite at STP. Our model examines the possibility that dissolving olivines with compositions between Fo(sub 0.9) and Fo(sub 0.4) can produce a strong gradient of Fe(2+) at pHs from 7 to 12 such that the precipitation of pyrrhotite will be initiated at the olivine-fluid boundary. Since CM phase equilibria is consistent with highly reducing conditions, Fe released by olivines would largely remain in solution as Fe(2+) until the solubility product of a Fe(2+) bearing phase was exceeded. Our calculations indicate that all examined combinations of olivine composition and pH yield a strong Fe(2+) gradient at the time the pyrrhotite solubility is exceeded near the olivine-fluid boundary. This favors the initiation of sulfide precipitation around dissolving olivines. However, sulfide rinds are not observed around all partially dissolved olivine grains in CM chondrites, which suggests that the availability of aqueous sulfide species limits the production of the thin sulfide rinds.

Reconstructing the thermal evolution of the CK chondrite parent body using Northwest Africa 5343, the least metamorphosed CK chondrite

Carbonaceous chondrites (CCs) represent some of the most pristine solar system material, providing constraints on the early formation of planetesimals. The CK chondrites are the only group of CCs to exhibit the full range of thermal metamorphism (petrologic type 3 to 6). Most unequilibrated CK chondrites (CK3s) have been metamorphosed to petrologic subtype 3.8 or higher. However, homogeneity of olivine suggests that CK3 chondrite Northwest Africa (NWA) 5343 is less metamorphosed than the other CK3s. The presence of unrecrystallized matrix indicates that it is less than petrologic type 3.7. To better assess the lower limits of metamorphism on the CK chondrite parent body, we performed a detailed analysis of matrix material in NWA 5343. Ascertaining the lower limit of metamorphism in the CK chondrites is critical when addressing the CK-CV parent body debate (e.g., one vs. two parent bodies), and will shed light onto the evolution of metamorphosed CC parent bodies. We recognize two texturally distinct regions in the matrix of NWA 5343. Both have similar mineralogies (mostly olivine with lesser pyroxene and plagioclase), but differ in grain size, shape, and porosity. The porous region of the sample is characterized by subhedral-rounded olivine grains, typically < 40 µms, surrounded by empty pore space ( 10-14% porosity). Some small patches of matrix within the porous region contain angular olivine grains that are < 10 µms, similar to "clastic matrix" typically observed in some low petrologic type CCs and ordinary chondrites (OCs). In the glassy matrix region of NWA 5343 (3-7% porosity), olivine grains are larger (20-40 µms) and more anhedral. Skeletal pyroxene is also common. Original pore space is filled with a Ca-rich glass that appears to originate from an unusual vein in this region. Most interestingly, the extent of metamorphism varies within NWA 5343. Larger, anhedral olivine in the glassy region suggest that this region is more metamorphosed than the porous region. Even within the porous region there is a range of metamorphism, with small patches of granoblastic olivine intermixed with the clastic matrix. This suggests that NWA 5343 may represent a metamorphic breccia, a common occurrence in OCs and CCs of lower petrologic types, and provides insight into the evolution of the only completely metamorphosed CC parent body.

Animal-assisted dyadic therapy: A therapy model promoting development of the reflective function in the parent-child bond.

Animal-assisted psychotherapy (AAP) inherently incorporates standpoints, interventions, and ways of action promoting the development of the reflective function and mentalization, and thus has special value for parent-child psychotherapy. Two central tools in AAP contribute to this process. The first is the ethical stance of the therapist, who sees the animals as full partners in the therapy situation, respecting them as subjects with needs, desires, and thoughts of their own. The second tool combines nonverbal communication with animals together with the relating, in the here and now, to the understanding and decoding of body language of everyone in the setting. Nonverbal communication in AAP enables access to implicit communication patterns occurring between parent and child. This article provides a survey of theoretical development and research constituting a basis for the development of therapeutic approaches for the improvement of parent-children dynamics, followed by a description of a dyadic therapy model of a mentalization-based treatment originating from a psychoanalytic-relational orientation. Clinical examples are provided to illustrate AAP processes in parent-child psychotherapy (consent was received for examples that were not aggregated).

The use of the nest for parental roosting and thermal consequences of the nest for nestlings and parents.

At temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season. Thus, energy costs of thermoregulation might constrain nestling growth, and low nocturnal temperatures might require resources that parents could otherwise have invested into nestlings during the day. To manipulate parental work rate, we performed brood size manipulations in breeding marsh tits ( Poecile palustris ). Nest box temperatures were always well above ambient temperature and increased with increasing brood size. In line with predictions, a large majority of females (but no males) made use of this benign environment for roosting. Furthermore, females tending enlarged broods, thereby having to work harder during the day, reduced their body temperature at night. This might have reduced nocturnal energy expenditure. Our finding that a higher proportion of enlarged, as compared to control, females continued to use the nest box as roosting sites even after a simulated predation event despite increased vulnerability to predation, further highlighting the need for energy conservation in this group. High nest box attendance and reduced body temperature in brood-reduced females may indicate that these females prioritised self-maintenance by initiating other costly physiological adjustments, e.g. moult, when relieved from parental work. We suggest that the energy demand for defending homeothermy is an element of the general trade-off between current and future reproduction, i.e. between daytime investment in food provisioning and the potential short- and long-term costs of a reduction in body temperature and increased predation risk. Even during summer at temperate latitudes, breeding birds need to use energy to maintain stable body temperature. Parents, thus, need to enter the night with sufficient body reserves to cover energy requirements for thermoregulation. As these resources could be used for feeding nestling during the day, adaptations to reduce the cost of thermoregulation would be selected for. We performed brood size manipulations, thereby increasing the need for nestling provisioning in marsh tits ( Parus palustris ). We found that females typically spent the night in the thermally benign environment of the nest box together with their brood. Females working hard during the day continued to roost in the nest box during the night despite an increase in the perceived risk of nest predation. Furthermore, these females reduced their body temperature at night, thereby reducing the gradient between ambient and body temperature, further reducing the cost of thermoregulation.

Parents have a fundamental role in promoting the healthy weight of their children. To determine parental perceptions of their child's body weight, eating and physical activity (PA) behaviours, and to test a predictive model of parental perceptions regarding their child's PA and healthy eating behaviours. A random-digit telephone survey was conducted among parents of children four to 12 years of age living in the Champlain region of Ontario. Descriptive statistics were used to summarize the responses. Path analysis was used to identify predictors of parental perceptions of PA and healthy eating. The study sample consisted of 1940 parents/caregivers. Only 0.2% of parents reported their child as being obese; 8.6% reported their child as being overweight. Most parents perceived their child to be physically active and eating healthily. Approximately 25% of parents reported that their child spent 2 h/day or more in front of a screen, and that their child consumed less than three servings of fruits and vegetables daily, and regularly consumed fast food. Variables that correlated with PA perceptions included time spent reading/doing homework, interest in PA, perceived importance of PA, frequency of PA, level of parental PA, participation in organized sport, child weight and parental concern for weight. Variables that predicted perceptions regarding healthy eating were parental education, household income, preparation of home-cooked meals, fruit and vegetable intake, and concern for and influence on the child's weight. Parents in the present study sample did not appear to understand, or had little knowledge of the recommendations for PA and healthy eating in children. Parents appeared to base their judgment of healthy levels of PA or healthy eating behaviours using minimal criteria; these criteria are inconsistent with those used by health professionals to define adequate PA and healthy eating. The present survey highlights an important knowledge gap between scientific opinion and parental perceptions of the criteria for healthy PA and eating behaviours.

Protein intake has been suggested to be associated with body composition among western children. Our aim was to determine whether protein intake is associated with body composition among Chinese children and to investigate whether parental socioeconomic status modifies these associations. Cross-sectional data were collected from the baseline survey of an ongoing population-based prospective open cohort study conducted in 2013. In this survey, 2039 children in South China were recruited using cluster random sampling. Information of 1704 children (47% girls), aged 7-12 years from three primary schools (42 classes), on diet and anthropometry was included finally. Their daily protein intake was obtained by 3-day 24-h dietary recalls. Skinfold thickness, body height, and weight were measured to calculate percent body fat (%BF), fat mass index (FMI), and fat-free mass index (FFMI). Parental characteristics were collected by questionnaires. Among girls, protein intake was positively associated with %BF and FMI [estimate (SE) for %BF: 0.007 (0.003), p = 0.04; for FMI: 0.092 (0.002), p = 0.03], adjusted for pubertal stage, breast-feeding, maternal overweight, carbohydrate intake, energy intake, and physical activity level. Furthermore, there was interaction between paternal occupation and the relations of dietary protein with %BF and FMI (p for interaction  ≤ 0.04). None of the associations between protein intake and %BF, FMI, or FFMI was found among boys. Our data indicate that school-aged girls, but not boys, living in South China with higher dietary protein intake might have higher body fat mass, which could be modified by paternal occupation.

Petrology of a nonindigenous microgranitic clast in polymict ureilite EET 87720: Evidence for formation of evolved melt on an unknown parent body

NASA Astrophysics Data System (ADS)

Beard, A. D.; Downes, H.; Chaussidon, M.

2015-09-01

EET 87720 is a polymict ureilite breccia known to contain numerous nonindigenous fragments. We have discovered a microgranitic clast in an interior chip of Elephant Moraine (EET) 87720. The clast consists of a granophyre-like intergrowth of a pure SiO2 phase (tridymite) and albite, mantling a zoned oligoclase phenocryst. In the intergrowth, the tridymite occurs as thin elongate vermicular blebs within larger albite crystals. The granophyre-like intergrowth and the oligoclase phenocryst share a common margin, suggesting that the clast was originally part of a larger fragment. An estimate of its bulk composition is equivalent to that of granite (77 wt% SiO2). Patches of high-Si K-bearing glass occur interstitially within the clast; they have high concentrations of SO3 (11-12 wt%) and contain Cl (0.6 wt%), suggesting that the clast formed on a volatile-rich parent body perhaps resembling early Mars. The mean oxygen isotope composition of the feldspar and tridymite in the clast is very different from the oxygen isotope compositions of ureilites, and is similar to those of silicate inclusions in IIE and IVA irons. Thus, the clast is not indigenous to the ureilite parent body, but it provides evidence for the formation of evolved melts on an unknown parent body in the early solar system.

Origin and history of ureilitic material in the solar system: The view from asteroid 2008 TC3 and the Almahata Sitta meteorite

NASA Astrophysics Data System (ADS)

Goodrich, Cyrena Anne; Hartmann, William K.; O'Brien, David P.; Weidenschilling, Stuart J.; Wilson, Lionel; Michel, Patrick; Jutzi, Martin

2015-04-01

Asteroid 2008 TC3 (approximately 4 m diameter) was tracked and studied in space for approximately 19 h before it impacted Earth's atmosphere, shattering at 44-36 km altitude. The recovered samples (>680 individual rocks) comprise the meteorite Almahata Sitta (AhS). Approximately 50-70% of these are ureilites (ultramafic achondrites). The rest are chondrites, mainly enstatite, ordinary, and Rumuruti types. The goal of this work is to understand how fragments of so many different types of parent bodies became mixed in the same asteroid. Almahata Sitta has been classified as a polymict ureilite with an anomalously high component of foreign clasts. However, we calculate that the mass of fallen material was ≤0.1% of the pre-atmospheric mass of the asteroid. Based on published data for the reflectance spectrum of the asteroid and laboratory spectra of the samples, we infer that the lost material was mostly ureilitic. Therefore, 2008 TC3 probably contained only a few percent nonureilitic materials, similar to other polymict ureilites except less well consolidated. From available data for the AhS meteorite fragments, we conclude that 2008 TC3 samples essentially the same range of types of ureilitic and nonureilitic materials as other polymict ureilites. We therefore suggest that the immediate parent of 2008 TC3 was the immediate parent of all ureilitic material sampled on Earth. We trace critical stages in the evolution of that material through solar system history. Based on various types of new modeling and re-evaluation of published data, we propose the following scenario. (1) The ureilite parent body (UPB) accreted 0.5-0.6 Ma after formation of calcium-aluminum-rich inclusions (CAI), beyond the ice line (outer asteroid belt). Differentiation began approximately 1 Ma after CAI. (2) The UPB was catastrophically disrupted by a major impact approximately 5 Ma after CAI, with selective subsets of the fragments reassembling into daughter bodies. (3) Either the UPB (before breakup), or one of its daughters (after breakup), migrated to the inner belt due to scattering by massive embryos. (4) One daughter (after forming in or migrating to the inner belt) became the parent of 2008 TC3. It developed a regolith, mostly ≥3.8 Ga ago. Clasts of enstatite, ordinary, and Rumuruti-type chondrites were implanted by low-velocity collisions. (5) Recently, the daughter was disrupted. Fragments were injected or drifted into Earth-crossing orbits. 2008 TC3 comes from outer layers of regolith, other polymict ureilites from deeper regolith, and main group ureilites from the interior of this body. In contrast to other models that have been proposed, this model invokes a stochastic history to explain the unique diversity of foreign materials in 2008 TC3 and other polymict ureilites.

Objective To examine the associations among self-reported loss-of-control (LOC) eating, emotion dysregulation, body mass, and objective energy intake among youth. Emotion dysregulation may be one individual factor that promotes excess energy intake and increases in body mass among youth with LOC eating. Methods Children and adolescents (N=230; 8 to 17 years) enrolled in a non-intervention study completed a structured interview to determine the presence or absence of self-reported LOC eating. Children’s emotion dysregulation was assessed via parent-report with the Child Behavior Checklist. Youth also completed two test meals to capture “binge” and “normal” eating. Body composition was examined using air displacement plethysmography. Results After controlling for relevant covariates, youth with self-reported LOC eating had higher parent-reported emotion dysregulation than those without LOC. Parent-reported emotion dysregulation was also associated with greater observed energy intake (after accounting for body mass), as well as higher fat mass. Emotion dysregulation also moderated associations between LOC status/sex and body mass variables; among youth with self-reported LOC eating and girls, those with high parent-described emotion dysregulation (versus low) had significantly higher fat mass and BMIz. Conclusions Data from the current study suggest that emotion dysregulation may play a role in energy intake and obesity, particularly among youth with self-reported LOC eating and girls. Additional studies are needed to identify the prospective mechanisms linking poor emotion regulation and LOC eating. These mechanisms, in turn, may inform future interventions targeting excess energy intake and obesity in pediatric samples. PMID:27505194

To examine a new socio-family risk model of Eating Disorders (EDs) using path-analyses. The sample comprised 1264 (ED patients = 653; Healthy Controls = 611) participants, recruited into a multicentre European project. Socio-family factors assessed included: perceived maternal and parental parenting styles, family, peer and media influences, and body dissatisfaction. Two types of path-analyses were run to assess the socio-family model: 1.) a multinomial logistic path-model including ED sub-types [Anorexia Nervosa-Restrictive (AN-R), AN-Binge-Purging (AN-BP), Bulimia Nervosa (BN) and EDNOS)] as the key polychotomous categorical outcome and 2.) a path-model assessing whether the socio-family model differed across ED sub-types and healthy controls using body dissatisfaction as the outcome variable. The first path-analyses suggested that family and media (but not peers) were directly and indirectly associated (through body dissatisfaction) with all ED sub-types. There was a weak effect of perceived parenting directly on ED sub-types and indirectly through family influences and body dissatisfaction. For the second path-analyses, the socio-family model varied substantially across ED sub-types. Family and media influences were related to body dissatisfaction in the EDNOS and control sample, whereas perceived abusive parenting was related to AN-BP and BN. This is the first study providing support for this new socio-family model, which differed across ED sub-types. This suggests that prevention and early intervention might need to be tailored to diagnosis-specific ED profiles. Copyright © 2015 Elsevier Ltd. All rights reserved.

Emotional distress and disordered eating practices among southern Italian women.

Cheney, Ann M

2012-09-01

This study is one of the first to examine the narrative links connecting social change, contested gender norms, body image, and eating disordered practices among southern Italian women. The research is based on 16 months of fieldwork, and I compare and contrast the stories of 23 educated women in southern Italy to highlight the contentious realities of entering adolescence in conservative social contexts where gender relations and value systems are undergoing rapid transformations. I examine how these young women dealt with conflicting cultural expectations of womanhood and whether it affected their emotional, psychological, and physical well-being. Their stories shed light on how parental control, community surveillance, and conflicts in developing gender identities and maturing womanly bodies contributed to their emotional distress. Distressed young women used rebellion and manipulation and control of food and the body to negotiate unjust social relations, specifically gender relations, that delegitimized their selves and, in some cases, their bodies.

The aim of this study was to assess and compare dietary intake and nutritional status of vegetarian and omnivorous preschool children and their parents. Fifty-six omnivores (28 children and 28 parents) and 42 vegetarians (21 preschool children with 18 lacto-ovo-vegetarians and 3 ovo-vegetarians; 21 parents with 16 lacto-ovo-vegetarians, 2 ovo-vegetarians, 1 lacto-vegetarian, and 2 vegans) were recruited. Anthropometric measurements were taken; body mass index and weight-for-height index (WHI) were calculated. Nutrient intake was recorded using 3-day dietary records. Fasting venous blood samples were obtained to estimate hematologic and vitamin status parameters. Height, weight, body mass index, WHI, and triceps skinfold thickness value differences between omnivores and vegetarians in both parent and child groups were not found. Both omnivorous parents and their children had significantly higher fat and lower fiber intakes than vegetarian parents and children. Omnivorous children had significantly higher protein and lower vitamin C intakes than vegetarian children, whereas omnivorous parents had significantly lower vitamin A and iron intakes than vegetarian parents. Vegetarians and omnivores in both parent and child groups had mean calcium consumption less than 75% of the Taiwan dietary intakes. All mean hematologic and biochemical nutrient status indices were within the reference range in any groups. However, both vegetarian parents and children had significantly lower mean total cholesterol and serum ferritin concentrations than those of omnivorous parents and children. Our vegetarian and omnivorous preschool children had normal growth and adequate nutritional status. However, both parents and children had inadequate calcium intakes, which may potentially affect bone health, especially for preschool children in the growing stage.

Spanish National Health Surveys do not establish synergistic relations between variables. The purpose of this study was to perform a deeper historical analysis of body mass index (BMI) and its relation to other parameters included in the questionnaire for children. Data from interviews conducted (between 1987 and 2006) to parents and guardians of schoolchildren aged 9-15 years were analyzed. Height and weight reported by parents were selected and used to calculate BMI. Subjects were stratified by age, gender, time spent sleeping and watching television and, finally, frequency of physical activity. The historical trend of BMI and its dependence on the above factors were analyzed using ANOVA tests. Significant weight and height increases were seen, which were more marked in boys aged 12 to 15 years. Influence of physical activity on BMI was shown, but decreased (P<.001) as exercise time increased. By contrast, BMI increased (P<.001) as time spent watching television increased. On the other hand, the role of sleep as modulator of body size was confirmed, since schoolchildren aged 9-11 years who slept over 9h had lower BMIs (P<.001). In subjects aged 12 to 15, BMI decreased (P<.001) from 6h of sleep. Copyright © 2012 SEEN. Published by Elsevier Espana. All rights reserved.

The aim of this study was to find out the association of media and obesity status with body weight concern among female university students in Kuwait. 228 female students, aged 19-25 years, were selected at convenience from the Women's College in Kuwait. A previously validated questionnaire was used to collect information on the role of media in body concern and how parents, peers and the girls themselves perceived girls' body shapes. Weight and height were gathered by self-reporting. Use of internet and reading women's magazines had a significant impact on dieting by the girls to lose weight (P<0.0007 and P<0.0114, respectively). The mass media had two to three times more influence on obese girls than non-obese girls. Only watching television had a significant impact on girls' body shape concern (P<0.053). About 30% of non-obese and 81% of obese girls were dissatisfied with their current weight. There were significant differences between obese and non-obese girls regarding the girls' views and the views of their peers and parents about the body weight of the girls (P<0.000 for all). The pressure from peers and parents, in addition to the mass media, may lead to disturbed attitudes towards eating among Kuwaiti girls. Copyright © 2012 Elsevier Ltd. All rights reserved.

While the prevalence of overweight and obesity is higher among children of some non-Western ethnic minorities than among their Caucasian counterparts, their body image is understudied. The current study examined the body image of Dutch children of non-Western ethnic minorities (i.e., Surinamese, Antillean, Moroccan, and Turkish). Sociocultural influences from school, media and home environments and their perceptions of overweight prevention programs were taken into account. Fifty-two non-Western ethnic minority children (aged 8-12 years) participated in semi-structured interviews and focus groups. Results showed that the children generally underestimated their current body size, which was often overweight, and preferred thin and 'normal' body sizes. Results further revealed important insights into culturally determined themes, relating to perceived preferences in media, peers, parents, and teachers, nutritional habits, and children's beliefs about school-based health interventions. We conclude that targeting culturally sensitive awareness about actual body size and healthy body images seems paramount in future interventions. Copyright © 2016 Elsevier Ltd. All rights reserved.

Poverty related disparities in early child development and school readiness are a major public health crisis, the prevention of which has emerged in recent years as a national priority. Interventions targeting parenting and the quality of the early home language environment are at the forefront of efforts to address these disparities. In this article we discuss the innovative use of the pediatric primary care platform as part of a comprehensive public health strategy to prevent adverse child development outcomes through the promotion of parenting. Models of interventions in the pediatric primary care setting are discussed with evidence of effectiveness reviewed. Taken together, a review of this significant body of work shows the tremendous potential to deliver evidence-based preventive interventions to families at risk for poverty related disparities in child development and school readiness at the time of pediatric primary care visits. We also addresss considerations related to scaling and maximizing the effect of pediatric primary care parenting interventions and provide key policy recommendations.

To investigate (1) the contributions of sex, age, nutritional status- and physical-fitness-related variables on health-related quality of life (HRQOL) in Spanish children with cystic fibrosis, and (2) the agreement on HRQOL between children and their parents. In 28 children aged 6-17 years, body mass index percentile, percentage body fat, physical activity, pulmonary function, cardiorespiratory fitness, functional mobility, and dynamic muscle strength were determined using objective measures. HRQOL was measured using the revised version of the cystic fibrosis questionnaire. Simple and multiple linear regression analyses were performed to determine the variables associated with HRQOL. To assess the agreement on HRQOL between children and parents, intra-class correlation coefficients (ICCs) were calculated. Girls reported worse emotional functioning, a higher treatment burden, and more respiratory problems than boys. Greater functional mobility appeared associated with a less favourable body image and more eating disturbances. Agreement on HRQOL between children and parents was good to excellent, except for the domain of treatment burden. Sex and age were stronger predictors of HRQOL than nutritional status- or physical-fitness-related variables. Children reported a lower treatment burden than their parents perceived them to have.

Physical inactivity is associated with poor physical fitness and increased body weight. This study examined the relationship between participation in organized sports and overweight as well as physical fitness in primary school children in southern Germany. Height, weight, and various components of physical fitness were measured in 995 children (7.6 ± 0.4 years). Sports participation and confounding variables such as migration background, parental education, parental body weight, and parental sports participation were assessed via parent questionnaire. Multiple logistic regression as well as multivariate analysis of covariance (MANCOVA) was used to determine associations between physical fitness, participation in organized sports, and body weight. Participation in organized sports less than once a week was prevalent in 29.2%, once or twice in 60.2%, and more often in 10.6% of the children. Overweight was found in 12.4% of the children. Children participating in organized sports more than once per week displayed higher physical fitness and were less likely to be overweight (OR  =  0.52, P < 0.01). Even though causality cannot be established, the facilitation of participation in organized sports may be a crucial aspect in public health efforts addressing the growing problems associated with overweight and obesity.

We attached 11 g (1.4% body-mass equivalent) global location sensing (GLS) archival tag packages to tarsi of 25 breeding sooty shearwaters (Puffinus griseus, titi) on Whenua Hou (Codfish Island), New Zealand during the chick-rearing period in 2005. Compared with chicks reared by non-handled adults that did not carry tags, deployment of tags on one or both adult parents ultimately resulted in 35% reduction in chick body mass and significantly reduced chick skeletal size preceding fledging (19 April). However, body mass between chick groups was not significantly different after controlling for skeletal size. Effects on chicks were more pronounced in six pairs where both parents carried tags. Chick mass was negatively related to the duration that adults carried tags. In this study, none of the chicks reared by pairs where both parents were tagged, 54% of chicks reared by pairs where one parent was tagged, and 83% of chicks reared by non-handled and non-tagged parents achieved a previously determined pre-fledging mass threshold (564 g; Sagar & Horning 1998). Body mass of adults carrying tags and returning from transequatorial migration the following year were 4% lighter on average than non-tagged birds, but this difference was not statistically significant. Reduced mass among chicks reared by adults carrying tags during the chick-provisioning period indicated that adults altered "normal" provisioning behaviours to maintain their own body condition at the expense of their chicks. Population-level information derived from telemetry studies can reveal important habitat-linked behaviours, unique aspects of seabird foraging behaviours, and migration ecology. Information for some species (e.g., overlap with fisheries) can aid conservation and marine ecosystem management. We advise caution, however, when interpreting certain data related to adult provisioning behaviours (e.g., time spent foraging, provisioning rates, etc.). If effects on individuals are of concern, we suggest shorter-term deployments, smaller and lighter tags, and alternative attachment techniques, especially when investigating threatened or endangered species. ??

Lugmair, G. W.

2003-01-01

During the grant period we have concentrated on the following main topics: 1. Enstatite meteorites and original heterogeneity of Mn-53 distribution in the solar nebula. We have completed our studies of the enstatite chondrites. 2. Processes of planetary differentiation. We have completed our study of silicate clasts from the mesosiderite Vaca Muerta and found that the global Mn/Cr fractionation event that established mantle source reservoirs on the parent body of the Vaca Muerta silicate clasts occurred approx. 2 Ma after a similar event on the howardite-eucrite-diogenite (HED) parent body. 3. Carbonaceous chondrites. Much effort has been devoted during the last three years to the investigation of this important class of meteorites. 4. Early solar system timescales. Based on the studies of the Mn-53 - Cr-53 isotope system in various meteorites and using results obtained with other isotope chronometers we constructed an absolute time-scale for events in the early solar system. 5.Unusual meteorites. We have studied the anomalous pallasite Eagle Station. 6. The chromium isotopic composition as a tracer for extraterrestrial material on Earth. Based on the observed difference in the Cr-53/Cr-52 ratios between Earth and the other solar system objects we developed a method for detecting cosmic materials on Earth using the Cr-53/Cr-52 ratio as a tracer.

Rotational spectral variations of asteroid (8) Flora Implications for the nature of the S-type asteroids and for the parent bodies of the ordinary chondrites

The surface material and the surface material heterogeneities of the asteroid Flora are characterized using the best available data sets and the most sophisticated interpretive calibrations. Five spectrally derived mineralogic and patrologic properties of the surface assemblage of Flora which are relevant to whether this body is a differentiated or undifferentiated object are considered: bulk mineralogy, mafic mineral assemblage, metallic phase, pyroxene composition and structural type, and mineralogic variation. All of these properties indicate that Flora is a differentiated body. Flora is probably the residual core of an intensely heated, thermally evolved, and magnetically differentiated planetesimal which was subsequently disrupted. The present surface sample layers formed at or near the core-mantle boundary in the parent body.

This study examined and compared sources of health-related information accessed by female college students with and without body image distortions, and the believability of those sources. Survey data from the American College Health Association, National College Health Assessment were studied retrospectively (N = 27,648). Body image distorted (BID) and non-BID students' most frequent health information sources were parents (76.1% BID; 77.1% non-BID) and internet (70.3% BID; 69.5% non-BID). Believability was greatest for health educators (90.6% BID; 91.1% non-BID) and lowest for television (14.4% BID; 14.5% non-BID). Health intervention strategies for college women should market to parents and teach recognition of credible internet sources of health information.

This study evaluated changes in both physical and psychosocial quality of life reported by the parent and child after surgical repair of pectus excavatum. As part of a multicenter study of pectus excavatum, a previously validated tool called the Pectus Excavatum Evaluation Questionnaire was administered by the research coordinator, via telephone, to parents and patients (8-21 years of age) before and 1 year after surgery. Eleven North American children's hospitals participated. From 2001 to 2006, 264 patients and 291 parents completed the initial questionnaire, and 247 patients and 274 parents completed the postoperative questionnaire. Responses used a Likert-type scale of 1 to 4, reflecting the extent or frequency of a particular experience, with higher values conveying less-desirable experience. Preoperative psychosocial functioning was unrelated to objective pectus excavatum severity (computed tomographic index). Patients and their parents reported significant positive postoperative changes. Improvements occurred in both physical and psychosocial functioning, including less social self-consciousness and a more-favorable body image. For children, the body image component improved from 2.30+/-0.62 (mean+/-SD) to 1.40+/-0.42 after surgery and the physical difficulties component improved from 2.11+/-0.82 to 1.37+/-0.44. For the parent questionnaire, the child's emotional difficulties improved from 1.81+/-0.70 to 1.24+/-0.36, social self-consciousness improved from 2.86+/-1.03 to 1.33+/-0.68, and physical difficulties improved from 2.14+/-0.75 to 1.32+/-0.39. Ninety-seven percent of patients thought that surgery improved how their chest looked. Surgical repair of pectus excavatum can significantly improve the body image difficulties and limitations on physical activity experienced by patients. These results should prompt physicians to consider the physiologic and psychological implications of pectus excavatum just as they would any other physical deformity known to have such consequences.

Organic compounds in carbonaceous chondrites were likely transformed by a variety of parent body processes including thermal and aqueous processing. Here, we analyzed ammonium cyanide reactions that were heated at different temperatures and times by multiple analytical techniques. The goal of this study is to better understand the effect of hydrothermal alteration on cyanide chemistry, which is believed to be responsible for the abiotic synthesis of purine nucleobases and their structural analogs detected in carbonaceous chondrites.

Grimm, R. E.

1985-01-01

The thermal histories of ordinary chondrites and the canonical internal heating or onion shell models, which predict an inverse relation between the petrologic type of chondrites and the metallographic cooling rate, are reviewed. The thermal and accretional requirements of the 'metamorphosed planetesimal' model proposed by Scott and Rajan (1981) are analyzed, and an alternative model consistent with the metallographic cooling rate constraints is suggested in which ordinary chondrite parent bodies are collisionally fragmented and then rapidly reassembled before metamorphic heat has been dissipated.

Although it is generally believed that the secondary alteration phases observed in CM chondrites resulted from parent body reactions, the influence of nebular processing can not yet be dismissed. We have analyzed 5 CM falls using optical and electron microscopy to construct a comprehensive pictorial reference set of textural and mineralogical associations bearing on the origin of alteration products in these meteorites. Our analyses support pervasive aqueous alteration on the CM parent body, but they do not exclude the possibility of minor nebular alteration.

2017-02-28

Parents of children with rare conditions increasingly use the Internet to source information on their child's condition. This study reports on part of a larger study whose overall aim was to identify the Internet use by parents when seeking information on their child's rare condition, with the specific purpose of using the findings to aid in the development of a website specifically designed to meet the parents' needs. It presents findings on why these parents use the Internet, the information and support content they source, and the impact these resources have on their capacity to care for and manage their child's condition. To (1) ascertain parents' general Internet usage patterns, (2) identify the nature of the information parents most frequently searched for, and (3) determine the effect the Internet-sourced information had on parents of children with rare conditions. Data collection was conducted in 2 parts: Part 1 was a focus group interview (n=8) to inform the development of the questionnaire, and Part 2 was a questionnaire (Web- and paper-based). All respondents (N=128) completed the questionnaire using the Internet. Parents frequently and habitually used the Internet and social media to gather information on their child's condition. These Web-based resources provide parents with a parent-to-parent support platform that allows them to share their experiences and information with other parents, which, the respondents considered, improved their knowledge and understanding of their child's condition. The respondents also reported that these resources positively impacted on their decision making, care, and management of their child's condition. However, they reported receiving mixed responses when wishing to engage and share with health care professionals their Internet and social media interactions and information outcomes. This study adds to the emerging body of research on the Internet use by parents of children with rare conditions to source information on their child's condition. The evolving and ever increasing parent-to-parent support systems via social media are impacting on parents' capacity to manage their children. Implications for practice include health care professionals' response to this knowledge and capacity shift, and the significance of these changes when interacting with parents. The key message of this study was that parents of children with rare conditions are habitual users of the Internet to source information about their children's conditions. Social media, especially Facebook, has an increasing role in the lives of these parents for information and support. Parents' interest in information gathering and sharing includes a desire for shared dialogue with health care professionals. ©Honor Nicholl, Catherine Tracey, Thelma Begley, Carole King, Aileen M Lynch.

Socioeconomic gradients in body mass index (BMI) in U.S. immigrants during the transition to adulthood: examining the roles of parental education and inter-generational educational mobility

PubMed Central

Albrecht, Sandra S.; Gordon-Larsen, Penny

2014-01-01

Background Despite comparatively lower socioeconomic status (SES), immigrants tend to have lower body weight and weaker SES gradients relative to U.S.-born individuals. Yet, it is unknown how changes in SES over the life-course relate to body weight in immigrants versus US-born individuals. Methods We used longitudinal data from a nationally-representative, diverse sample of 13701 adolescents followed into adulthood to investigate whether associations between SES mobility categories (educational attainment reported by individuals as adults and by their parents during adolescence) and body mass index (BMI) measured in adulthood varied by immigrant generation. Weighted multivariable linear regression models were adjusted for age, sex, race/ethnicity, and immigrant generation. Results Among first generation immigrants, although parental education was not associated with adult BMI, an immigrant’s own education attainment was inversely associated with BMI (β=−2.6 kg/m2; standard error (SE)=0.9, p<0.01). In addition, upward educational mobility was associated with lower adult mean BMI than remaining low SES (β= −2.5 kg/m2; SE=1.2, p<0.05). In contrast, among U.S.-born respondents, college education in adulthood did not attenuate the negative association between parental education and adult BMI. Although an SES gradient emerged in adulthood for immigrants, remaining low SES from adolescence to adulthood was not associated with loss of health advantage relative to U.S.-born respondents of U.S.-born parents of similar SES. Conclusion Immigrants were able to translate higher SES in adulthood into a lower adult mean BMI regardless of childhood SES, whereas the consequences of lower childhood SES had a longer reach even among the upwardly mobile U.S.-born.

A higher prevalence of obesity in lower socioeconomic classes is common in Western societies. This study examined the role of gene-environment interactions in the association between parental education and body mass index (BMI) from infancy to the onset of adulthood. Parentally reported BMI from 1 to 13 and self-reported BMI from 14 to 20 years of age were collected in 16,646 complete Dutch twin pairs and analyzed by genetic twin modeling. At 7 to 8 years of age, children whose parents had middle or low educational levels had more excess weight than the children of more highly educated parents, and the difference increased until 18 to 20 years of age. The major part of the BMI variation was explained by additive genetic factors (a(2)  = 0.55-0.85), but environmental factors common for co-twins also played a significant role, especially from 3 to 7-8 years of age (c(2)  = 0.15-0.29). The genetic variation in BMI was higher in children whose parents had middle or low educational levels compared with children whose parents had a high educational level. The interaction between genetic factors and the childhood social environment may contribute to the formation of socioeconomic differences in obesity. © 2016 The Obesity Society.

Body weight of children is affected by many factors including food habits which are influenced by their parents. Studies in the West have shown that parents tend to control child feeding in response to their child's weight status. The aim of this study was to assess Malaysian parental concerns about child weight and the control they exert on child feeding. This cross-sectional study was conducted on parents and their children aged 9 to 12 years from a primary school in Kuala Lumpur. The weight status of the children was classified according to the body mass index-for-age growth chart. Parental concerns about child weight and control in child feeding was assessed using the adapted Malay version of Child Feeding Questionnaire. A total of 204 parents participated in this study. The study found that being a female served as a protective factor against becoming overweight (OR: 0.28, CI: 0.13-0.62). Parents with overweight children were significantly older (OR: 1.08, CI: 1.01-1.15), concerned about their child's weight (OR: 2.77, CI: 1.49-5.12) and controlled their child's feeding by restricting food intake (OR: 2.70, CI: 1.30-5.60). They were less likely to pressure their children to eat (OR: 0.32, CI: 0.19-0.56). Parents from the low income group were more likely to have underweight children (OR: 4.15, CI: 1.28-13.47). There was significant difference in level of parental concern across differing child weight status. Parents with overweight children were likely to be more concerned about their child's weight, tending to control their feeding. In contrast, parents with underweight children did not exert control on their feeding.

Until a century ago, Korean medicine was based mainly on Oriental philosophies and ideas. From a religious perspective, Chinese Confucianism was prevalent in Korea at that time. Since Confucianists believe that it is against one's filial duty to harm his or her body, given to them by their parents, most Koreans did not donate their bodies or organs for education in the past. However, by the end of the 20th century, a unique fusion of Western and Oriental medicines were produced on the Korean Peninsula, revolutionizing traditional perspectives on the human body, mortality, and the relationship of medical science to society. Koreans began to think about others' lives as well as their own by realizing the importance of donating one's organs and bodies for scientific purposes. Since then, the number of people donating their bodies to Korean medical and dental schools for the purpose of improving academic learning has increased dramatically. In response, Korean medical schools have begun to hold various types of funeral ceremonies to honor body donors. We have compared such ceremonies performed in Korea with those performed in the United States of America and Taiwan. These ceremonies are viewed as a suitable way to pay proper respect to the dead and to promote knowledge about body donation programs in Korea. Overall, the transition of religions and social ethics in Korea has greatly facilitated body bequeathal programs, benefiting both medical education and the Korean public health administration.

2013-01-01

Growing Right Onto Wellness (GROW) is a randomized controlled trial that tests the efficacy of a family-centered, community-based, behavioral intervention to prevent childhood obesity among preschool-aged children. Focusing on parent-child pairs, GROW utilizes a multi-level framework, which accounts for macro (i.e., built-environment) and micro (i.e., genetics) level systems that contribute to the childhood obesity epidemic. Six hundred parent-child pairs will be randomized to a 3-year healthy lifestyle intervention or a 3-year school readiness program. Eligible children are enrolled between ages 3 and 5, are from minority communities, and are not obese. The principal site for the GROW intervention is local community recreation centers and libraries. The primary outcome is childhood Body Mass Index (BMI) trajectory at the end of the three-year study period. In addition to other anthropometric measurements, mediators and moderators of growth are considered, including genetics, accelerometry, and diet recall. GROW is a staged intensity intervention, consisting of intensive, maintenance, and sustainability phases. Throughout the study, parents build skills in nutrition, physical activity, and parenting, concurrently forming new social networks. Participants are taught goal-setting, self-monitoring, and problem solving techniques to facilitate sustainable behavior change. The GROW curriculum uses low health literacy communication and social media to communicate key health messages. The control arm is administered to both control and intervention participants. By conducting this trial in public community centers, and by implementing a family-centered approach to sustainable healthy childhood growth, we aim to develop an exportable community-based intervention to address the expanding public health crisis of pediatric obesity.

The aim of this study was to examine any differences in cardiovascular disease (CVD) risk in Portuguese children split by parental educational level. A cross-sectional school-based study was conducted in 2011 on 359 Portuguese children (202 girls and 157 boys) aged 10 to 17 years (mean age ± SD = 13.9 ± 1.98 years). Height and body mass were assessed to determine body mass index (BMI). Parental education level (PEL) was used as a surrogate for socioeconomic status (SES). Capillary blood sampling was used to determine: Total Cholesterol (TC), Triglycerides (TG), Fasting Glucos (GLUC), High and Low Density Lipoprotein (HDL/LDL). These measurements were combined with measures of systolic blood pressure and cardiorespiratory fitness as z-scores. CVD risk was constructed by summing the z-scores. Analysis of covariance, controlling for BMI, indicated that CVD risk was significantly different across PEL groups (p = 0.01), with CVD risk score being significantly lower in low (p = 0.04) and middle (p = 0.008) PEL groups, compared to high PEL. Moreover, the covariate, BMI was also significant (p = 0.0001, β = 0.023), evidencing a significant positive association between BMI and CVD risk, with higher BMI associated with greater CVD risk. In Portuguese children, significantly greater CVD risk was found for children of high PEL, while higher BMI was associated with greater CVD risk. PMID:23330223

Nine inter-generic somatic hybrids named as pfle were produced through PEG-mediated protoplast fusion between Pleurotus florida and Lentinula edodes using double selection method. Hybridity of the newly developed strains was established on the basis of colony morphology, mycelial growth, hyphal traits, fruit-body productivity and inter single sequence repeat (ISSR) marker profiling. Hybrid population was assessed with different phenotypic variables by one-way analysis of variance. Principal component matrices were analyzed for the six phenotypic variables in scatter plot showing maximum positive correlation between each variable for all strains examined. Six ISSR primers generated 66 reproducible fragments with 98.48 % polymorphism. The dendrogram thus created based on unweighted pair-group method with mathematic averages method of clustering and Euclidean distance which exhibited three major groups between the parents and pfle hybrids. Though P. florida parent remained in one group but it showed different degrees of genetic distance with all the hybrid lines belonging to the other two groups while L. edodes was most distantly related to all the hybrid lines. L. edodes specific sequence-rich ISSR amplicon was recorded in all the hybrid lines and in L. edodes but not in P. florida. All the fruit body generating pfle hybrid lines could produce basidiocarp on paddy straw in sub-tropical climate and showed phenotypic resemblance to the P. florida parent.

Intrauterine growth restriction (IUGR) and fetal growth restriction (FGR) are pregnancy complications associated with morbidity in later life. Despite a growing body of evidence from current research on developmental origins of health and disease (DOHaD), little information is currently provided to parents on long-term metabolic, cardiovascular and neurologic consequences. As parents strongly rely on internet-based health-related information, we examined the quality of information on IUGR/FGR sequelae and DOHaD in webpages used by laypersons. Simulating non-clinicians experience, we entered the terms 'IUGR consequences' and 'FGR consequences' into Google and Yahoo search engines. The quality of the top search-hits was analyzed with regard to the certification through the Health On the Net Foundation (HON), currentness of cited references, while reliability of information and DOHaD-related consequences were assessed via the DISCERN Plus score (DPS). Overall the citation status was not up-to-date and only a few websites were HON-certified. The results of our analysis showed a dichotomy between the growing body of evidence regarding IUGR/FGR-related sequelae and lack of current guidelines, leaving parents without clear directions. Furthermore, detailed information on the concept of DOHaD is not provided. These findings emphasize the responsibility of the individual physician for providing advice on IUGR/FGR-related sequelae, monitoring and follow-up.

Asteroid families from cratering: Detection and models

A new asteroid families classification, more efficient in the inclusion of smaller family members, shows how relevant the cratering impacts are on large asteroids. These do not disrupt the target, but just form families with the ejecta from large craters. Of the 12 largest asteroids, 8 have cratering families: number (2), (4), (5), (10), (87), (15), (3), and (31). At least another 7 cratering families can be identified. Of the cratering families identified so far, 7 have >1000 members. This imposes a remarkable change from the focus on fragmentation families of previous classifications. Such a large dataset of asteroids believed to be crater ejecta opens a new challenge: to model the crater and family forming event(s) generating them. The first problem is to identify which cratering families, found by the similarity of proper elements, can be formed at once, with a single collision. We have identified as a likely outcome of multiple collisions the families of (4), (10), (15), and (20). Of the ejecta generated by cratering, only a fraction reaches the escape velocity from the surviving parent body. The distribution of velocities at infinity, giving to the resulting family an initial position and shape in the proper elements space, is highly asymmetric with respect to the parent body. This shape is deformed by the Yarkovsky effect and by the interaction with resonances. All the largest asteroids have been subjected to large cratering events, thus the lack of a family needs to be interpreted. The most interesting case is (1) Ceres, which is not the parent body of the nearby family of (93). Two possible interpretations of the low family forming efficiency are based on either the composition of Ceres with a significant fraction of ice, protected by a thin crust, or with the larger escape velocity of ~500 m/s.

Recent years have witnessed a significant increase in the sophistication of asteroidal surface material characterizations derived from spectral data. An extensive data base of moderate to high spectral resolution, visible and near-infrared asteroid spectra is now available. Interpretive methodologies and calibrations were developed to determine phase abundance and composition in olivine-pyroxene assemblages and to estimate NiFe metal abundance from such spectra. A modified version of the asteroid classifications system more closely parallels the mineralogic variations of the major inner belt asteroid types. These improvements permit several general conclusions to be drawn concerning the nature of inner belt objects; their history, and that of the inner solar system; and the relationship between the asteroids and meteorites. Essentially all large belt asteroids have or are fragments of parent bodies which have undergone strong post-accretionary heating, varying degrees of melting and magmatic differentiation, and subsequent collisional disruption. These asteroids show a systematic, but not yet well characterized, mineralogic variation with semi-major axis. This suggests that the S-type asteroid families represent relatively recent collisions onto the cores of previously disrupted parent bodies.

To determine what factors are associated with parental motivation to change body weight in overweight children. Cross-sectional study. Dunedin, New Zealand. Two hundred and seventy-one children aged 4-8 years, recruited in primary and secondary care, were identified as overweight (BMI ≥ 85th percentile) after screening. Parents completed questionnaires on demographics; motivation to improve diet, physical activity and weight; perception and concern about weight; parenting; and social desirability, prior to being informed that their child was overweight. Additional measures of physical activity (accelerometry), dietary intake and child behaviour (questionnaire) were obtained after feedback. Although all children were overweight, only 42% of parents perceived their child to be so, with 36% indicating any concern. Very few parents (n 25, 8%) were actively trying to change the child's weight. Greater motivation to change weight was observed for girls compared with boys (P = 0.001), despite no sex difference in BMI Z-score (P = 0.374). Motivation was not associated with most demographic variables, social desirability, dietary intake, parenting or child behaviour. Increased motivation to change the child's weight was observed for heavier children (P < 0.001), those who were less physically active (P = 0.002) and more sedentary (P < 0.001), and in parents who were more concerned about their child's weight (P < 0.001) or who used greater food restriction (P < 0.001). Low levels of parental motivation to change overweight in young children highlight the urgent need to determine how best to improve motivation to initiate change.

Personal Space Regulation in Williams Syndrome: The Effect of Familiarity.

Personal space refers to a protective barrier that we strive to maintain around our body. We examined personal space regulation in young people with Williams syndrome (WS) and their typically developing, chronological age-matched peers using a parent report questionnaire and a stop-distance paradigm. Individuals with WS were reported by their parents to be more likely to violate the personal space of others, and indeed they maintained a shorter interpersonal distance in the stop-distance paradigm. Interestingly, WS individuals failed to regulate their personal space based on the familiarity of the person they were interacting with. Findings are discussed in relation to the wider social profile associated with WS, and the possible impact of atypical personal space regulation on social vulnerability.

Background Few effective community-based interventions exist for early childhood obesity. Parent mentors have been successful as an intervention for other conditions, but have not been used for childhood obesity. We designed an intervention for early childhood obesity using parent mentors and a positive outlier approach to assess potential efficacy, feasibility, and acceptability. Methods This trial enrolled obese (≥95th BMI percentile for age and gender) 2-5-year-old children in a Head Start program and their parents, with allocation to either parent mentors trained in positively deviant behaviors regarding childhood obesity, or community health workers delivering health education on obesity-related behaviors. The primary outcome is body mass index z-score change at the six-month follow-up assessment. Secondary outcomes include feeding behaviors and practices, health-related quality of life, dietary intake, and participation levels. Results We enrolled three parent mentors and 60 parent-child dyads. The population is 100% Hispanic; 44% of parents speak Spanish as their primary language and 45% were not high-school graduates. Children had a reported median vegetable and fruit intake of 0.3 and 1.1 cups per day, respectively, at baseline, and a median daily screen time of three hours. There was no intergroup difference in quality-of-life scores at baseline. Retention has been high, at 90% at three months. Conclusions In this randomized trial of the effects of parent mentors on early childhood obesity, parent-child dyads from an underserved, Hispanic population were successfully enrolled through a partnership with a Head Start organization, with a high retention rate.

Concerns of a growing obesity epidemic have increased since the association between obesity in parents and that in offspring was reported. However, the evidence regarding whether the energy-saving efficiency of obese parents is conveyed to their offspring and the duration of the expression of such transmitted efficiency is limited. We included 7647 matching sets of parent-offspring trios from South Korea. Multiple linear regression models were performed to estimate the energy-saving efficiency, as assessed by the associations between energy intake and obesity-related indices (waist-to-height ratio, waist circumference and body mass index z-score), and to compare the energy-saving efficiency of offspring of obese and non-obese parents. All analyses were based on a complex sample design and were stratified by gender and age. We identified a parental influence on obesity, that is, the more obese the parent, the higher the obesity-related indices of their offspring, in both genders and all age groups. The energy-saving efficiency of child offspring was highest when both parents were obese and lowest when both were non-obese; this difference was significant (P<0.05) with regard to the energy-saving efficiency of all types of intake studied, except fat. However, the energy-saving efficiency of obese and non-obese parents did not differ when their offspring were adolescents and adults. The critical window for transmission of energy-saving efficiency is limited to childhood. These findings suggest that children of obese parents should be more emphatically advised to maintain a balanced diet and to engage in regular physical activity.

Physical activity (PA) is associated with health benefits, already in childhood. However, little is known about actual levels, patterns and gender differences in PA level in very young children. This study examines Chinese one-year-old children and their parents' PA levels and patterns, and assesses the correlations between children's PA level and gender, body mass index standard deviation score (BMI SDS), parental BMI and parental PA level. Data from 123 families participating in the Early STOPP China study were used. Families were recruited based on parental BMI and were classified as either high-risk or low-risk of obesity. Parents and children wore an ActiGraph GT3X+ to assess the average PA levels. PA levels and hourly patterns during weekdays and weekends were examined as were correlations with gender, BMI SDS, parental BMI and parental PA levels. There were no significant differences in children's averaged PA between risk groups, genders, or between weekdays and weekends. Children's peak average activity level was at 7 pm and they were least active at 3 pm (p<0.001). Both mothers and fathers demonstrated a similar PA pattern as their children, although paternal PA level was consistently lower than that of mothers and children. No significant association was found between children's PA and their gender, BMI SDS, parental BMI or paternal PA levels. Maternal PA was found positively associated with child PA (p<0.05). PA in one-year-old Chinese children vary over the day but weekdays and weekends are similar. At this age, children's PA is not related to gender, BMI SDS, parental BMI or paternal PA. Larger scale studies with more contextual information are needed to improve the understanding of our findings.

Objective To characterize the knowledge, attitudes, and beliefs (KAB) regarding childhood obesity among parents of Latino preschoolers. Methods Three hundred sixty-nine Mexican immigrant parents of children ages 2–5 were interviewed. Children were weighed and measured. Results Parents underestimated their own child’s weight status and had high levels of perceived control over their children’s eating and activity behaviors. Parents of overweight (≥95%ile-for-age-and-sex BMI) versus nonoverweight (<95%ile BMI) children did not differ in their beliefs about ideal child body size. Conclusion Latino parents of overweight children did not differ from parents of nonoverweight children with respect to their KAB about childhood obesity. PMID:20001191

Objective The aim of this study was to investigate the prevalence of overweight/obesity among parents of children entering childhood obesity treatment and to evaluate changes in the parents’ weight statuses during their child’s treatment. Methods The study included parents of 1,125 children and adolescents aged 3–22 years, who were enrolled in a multidisciplinary childhood obesity treatment program. At baseline, weight and height of the parents were obtained by self-reported information and parental body mass index (BMI) was calculated. Weight and height of the children were measured in the clinic and BMI standard deviation scores were calculated. Furthermore, anthropometric data from parents of 664 children were obtained by telephone interview after a mean of 2.5 years of treatment (ranging 16 days to 7 years), and changes in parental BMI were analyzed. Results Data on changes in BMI were available in 606 mothers and 479 fathers. At baseline, the median BMI of the mothers was 28.1 kg/m2 (range: 16.9–66.6), and the median BMI of the fathers was 28.9 kg/m2 (range: 17.2–48.1). Seventy percent of the mothers and 80% of the fathers were overweight or obese at the time of their child’s treatment initiation. Both the mothers and fathers lost weight during their child’s treatment with a mean decrease in BMI in the mothers of 0.5 (95% CI: 0.2–0.8, p = 0.0006) and in the fathers of 0.4 (95% CI: 0.2–0.6, p = 0.0007). Of the overweight/obese parents, 60% of the mothers and 58% of the fathers lost weight during their child’s treatment. Conclusion There is a high prevalence of overweight/obesity among parents of children entering childhood obesity treatment. Family-based childhood obesity treatment with a focus on the child has a positive effect on parental BMI with both mothers and fathers losing weight.

To investigate whether parental hypertension (HTN) affects children's body mass index (BMI) and cardiovascular reactivity (CVR) over time. A longitudinal study of 315 students (black: 23 females, 19 males; white: 142 females, 131 males) was conducted in the public schools of Obion County, Tennessee, between 1987 and 1992. BMI and BMI z scores were calculated. The CVR task was a series of video games (taking approximately 10 minutes to play) given to the same students in their third-, fourth-, fifth-, seventh-, and eighth-grade years. CVR was defined as the change in blood pressure (delta_BP) or heart rate (delta_HR) between before playing and while playing the video game. Positive parental history of HTN (27.6%) was defined as at least 1 parent with HTN. Multivariable regression analyses were performed to estimate the effects of parental HTN on children's BMI and CVR over time. Children with parental HTN had significant higher BMI, BMI z score, and R_BP than did children without parental HTN (BMI: 21.6 vs 19.9, P = .001; BMI z score: 1.6 vs 1.1, P = .003; R_SBP: 112.6 vs 110.4 mm Hg, P = .01; R_DBP 62.7 vs 60.6 mm Hg, P = .003) after adjustment for covariates. Increased CVR was observed in children with parental HTN compared with children without parental HTN but was statistically significant only for SBP (delta_SBP: 17.2 vs 14.9 mm Hg; P = .01) after adjustment for covariates. Parental HTN independently predicted children's BMI, BMI z score, resting BP, and BP reactivity.

International adoptions involve approximately 30000 children worldwide each year. Nearly all of the adoptive parents travel to the child's country of birth to meet them and bring them home. The objective of this study is to analyze the adoptive parents' account of their first meetings with their child. The study includes 46 parents who adopted one or more children internationally. Each parent participated in a semi-structured interview, focused on these first parent-child meetings. The interviews were analyzed according to a qualitative phenomenological method, Interpretative Phenomenological Analysis. The principal themes that emerged from the analysis of the interviews were: the scene when the child is entrusted to the parents, the discovery of the child's body, and the first parent-child interaction. Within these three principal themes, several subthemes dealt with difficult experiences: moments of solitude and anxiety, shocking images of the children's living conditions, lack of preparation and of information about the child, poor health, parental reactions of rejection, worry about the child's body, aggressive reactions by the child, worry about the child's reactions, and contrast with the expected interaction. Thirty-two interviews included at least one of these subthemes. At the structural level of the discourse; the characteristics of 33 interviews are those described in the literature as significantly more frequent in traumatized than in non-traumatized subjects. These results raise questions about the consequences of difficult, possibly traumatic experiences, at the moment of meeting the child, and they underline the need for work on preparation and prevention before the parents leave on their journey.

Chen, Jyu-Lin; Kennedy, Christine

2005-01-01

A cross-sectional study design was utilized to examine factors associated with obesity in Chinese-American children. Chinese-American children (8 to 10 years old) and their mothers (N = 68) in California participated in the study. Mothers completed demographic information, the Family Assessment Device, Attitudes Toward Child Rearing Scale, and Suinn-Lew Asian Self-identity Acculturation Scale. Children's body mass index was measured, and children completed a self-administered physical activity checklist, Food Frequency Questionnaire, and the Schoolagers' Coping Strategies Inventory. Results indicated three variables that predicted children's body mass index: older age, a more democratic parenting style, and poor communication (R2=.263, F=8.727, p = .0001). Children whose mothers had a low level of acculturation were also more likely to be overweight than were children whose mothers were highly acculturated. This study revealed that children's ages, a democratic parenting style, and poor family communication contribute to increased body mass index in Chinese-American children. Other factors related to children's BMI and dietary intake include acculturation level of the mother and family affective responses. Future studies should examine the change in BMI over time and in different age groups and why parenting and family communication impact children's body weight.

The link between symptoms of attention deficit hyperactivity disorder (ADHD) and increased body weight is well established, while the underlying mechanisms are not yet clear. Since increased body weight and ADHD symptoms have been found to be associated with psychosocial risk factors in childhood, we analyzed whether the psychosocial risks explain the association between the two conditions. The sample consisted of 360 children (age range 6-7 years, 173 boys) attending the obligatory medical health exam before school entry. The childrens' height and weight were measured during the examination. ADHD symptoms were ascertained by parent-report questionnaires. Psychosocial risks were ascertained by a structured interview. The link between ADHD symptoms and body weight could be completely explained by cumulative psychosocial risks while controlling for gender, symptoms of depression/anxiety and oppositional defiant disorder of the child, maternal smoking during pregnancy, parental body mass index, and potential diagnosis of ADHD in the parents. In current models pertaining to the etiology of overweight/obesity and ADHD, chronic stress caused by psychosocial adversity is assumed to act as a trigger for these conditions. Psychosocial risks experienced during childhood may activate processes that specifically lead to the combined ADHD-overweight phenotype.

Detailed analysis of the fireball 20160317_031654 over the United Kingdom

On March 17, 2016 in the early morning hours the UKMON network (United Kingdom Meteor Observation Network) cameras recorded a bright fireball with an absolute magnitude of -12.5 ± 0.4m, its atmospheric path began above the Dorset County and ended up above the Oxford County in the southern part of England. This fireball belonging to the Northern March gamma Virginids (IAU MDC #749 NMV) meteor shower was recorded from 8 cameras of the UKMON network. The atmospheric path of the bolide and the heliocentric orbit of the meteoroid are analyzed in this article. The flight of the fireball, whose absolute magnitude was comparable with the brightness of the Full Moon, was also observed by numerous random observers from the public in the United Kingdom, the Netherlands, Belgium and France. Numerical integration of the heliocentric orbit of the body and its clones was performed to find the potential parent body of the fireball and also the potential parent body of the meteor shower #749 NMV. However, no potential parent body of the fireball 20160317_031654 was found in the comets (periodic, non-periodic and lost) and asteroids database.

Investigation of the H7 ordinary chondrite, Watson 012: Implications for recognition and classification of Type 7 meteorites

Despite the fact that the number of officially classified meteorites is now over 45,000, we lack a clearly defined sequence of samples from a single parent body that records the entire range in metamorphic temperatures from pristine primitive meteorites up to the temperatures required for extensive silicate partial melting. Here, we conduct a detailed analysis of Watson 012, an H7 ordinary chondrite, to generate some clarity on the textural and chemical changes associated with equilibrium-based silicate partial melting in chondritic meteorites. To do this we compare the textures in the meteorite with those preserved in metamorphic contact aureoles on Earth. The most distinctive texture generated by the partial melting that affected Watson 012 is an extensively interconnected plagioclase network, which is clearly observable with a petrographic microscope. Enlarged metal-troilite grains are encapsulated at widenings in this plagioclase network, and this is clearly visible in reflected light. Together with these features, we define a series of other characteristics that can be used to more clearly classify chondritic meteorites as being of petrologic Type 7. To provide comprehensive evidence of silicate partial melting and strengthen the case for using simple petrographic observations to classify similar meteorites, we use high-resolution X-ray computed tomography to demonstrate that the plagioclase network has a high degree of interconnectedness and crystallised as large (cm-scale) skeletal crystals within an olivine-orthopyroxene-clinopyroxene framework, essentially pseudomorphing a melt network. Back-scattered electron imaging and element mapping are used to show that some of the clino- and orthopyroxene in Watson 012 also crystallised from silicate melt, and the order of crystallisation was orthopyroxene → clinopyroxene → plagioclase. X-ray diffraction data, supported by bulk geochemistry, are used to show that plagioclase and ortho- and clinopyroxene were added to the Watson 012 sample by through-flowing basaltic melt. Along with the absence of glass and granophyre, this interconnected network of coarse-grained skeletal plagioclase indicates that the sample cooled slowly at depth within the parent body. The evidence of melt flux indicates that Watson 012 formed in the presence of a gravitational gradient, and thus at significant distance from the centre of the H chondrite parent body (the gravitational gradient at the centre would be zero). Our interpretation is that incipient silicate partial melting in Watson 012 occurred when a region of radiogenically heated H6 material located at considerable depth (possibly at ∼15-20 km from surface) was heated by an additional ca. 200-300 °C in association with a large shock event. Due to insulation at depth within an already hot parent body, the post-shock temperature equilibrated and remained above the solidus long enough for widespread equilibrium-based silicate partial melting, and for melt to migrate. Although the observed melting may have been facilitated by additional heating from an impact event, this is not an example of instantaneous shock melting, which produces thermal disequilibrium at short length scales and distinctly different textures. A small number of H, L and LL chondrites have been previously classified as being of petrologic Type 7; with our new criteria to support that classification, these represent our best opportunity to explore the transition from high temperature sub-solidus metamorphism through the onset of silicate partial melting in three different parent bodies.

The purpose of this study was to investigate Korean preschoolers' obesity-related factors through an ecological approach and to identify Korean preschoolers' obesity-related factors and the different effects of ecological variables on body mass index and its quantiles through an ecological approach. The study design was cross-sectional. Through convenience sampling, 241 cases were collected from three kindergartens and seven nurseries in the Seoul metropolitan area and Kyunggi Province in April 2013 using self-administered questionnaires from preschoolers' mothers and homeroom teachers. Results of ordinary least square regression analysis show that mother's sedentary behavior (p < .001), sedentary behavior parenting (p = .039), healthy eating parenting (p = .027), physical activity-related social capital (p = .029) were significant factors of preschoolers' body mass index. While in the 5% body mass index distribution group, gender (p = .031), preference for physical activity (p = .015), mother's sedentary behavior parenting (p = .032), healthy eating parenting (p = .005), and teacher's sedentary behavior (p = .037) showed significant influences. In the 25% group, the effects of gender and preference for physical activity were no longer significant. In the 75% and 95% group, only mother's sedentary behavior showed a statistically significant influence (p < .001, p = .012 respectively). Efforts to lower the obesity rate of preschoolers should focus on their environment, especially on the sedentary behavior of mothers, as mothers are the main nurturers of this age group.

Brief Report: Parenting Styles and Obesity in Mexican American Children: A Longitudinal Study

PubMed Central

Power, Thomas G.

2010-01-01

Objective To assess longitudinally the relations between four parenting styles (authoritative, authoritarian, uninvolved, and indulgent) and child weight status in Mexican American families. Methods Sixty-nine low-income Mexican American mothers and their 4- to 8-year-old children participated in a 4-year longitudinal study. Mothers completed demographic and parenting measures. Children's body weight and height were assessed annually. Body mass index was calculated to determine weight status. Results At baseline, 65% of children were found to be normal weight, 14% were overweight, and 21% were obese. Analyses examined how parenting styles at baseline predicted child's weight status 3 years later, controlling for initial weight status. Children of indulgent mothers were more likely to become overweight 3 years later than children of authoritative or authoritarian mothers. Conclusions This study provides longitudinal evidence for the role of indulgent parenting in predicting overweight in Mexican American children. Possible mediating factors that may account for this relationship (e.g., dietary patterns, physical activity patterns, and children's self-regulation) are considered. PMID:19726552

Time matters for intersex bodies: Between socio-medical time and somatic time.

PubMed

Meoded Danon, Limor

2018-05-08

This article focuses on the dynamic relationships between time and intersex bodies that exist, on the one hand, in medical policy on intersex bodies and, on the other, in intersex people's subjective experiences. Time, from a sociological perspective, is a biosocial agent that establishes diagnostic practices, regulations, and treatment policy regarding intersex bodies. The systematic construction of timeframes by biomedical professionals aims to rapidly diagnose and treat intersex patients and is deeply rooted in the "dimorphic soma-gender order" (DMSGO), the imagined unified relationship of female bodies to femininity and male bodies to masculinity. From a socio-phenomenological perspective, I describe the concept of somatic time, which involves the relationship between time and the soma, the body's own particular clock and rhythms, according to which it grows, changes, and develops, and the body as a time capsule that stores experiences. I will illustrate the somatic time of intersex people and their subjective embodied experiences of the soma-gender relationship, and explore how their somatic time challenges biomedical timeframes. This qualitative study is based on narrative interviews with biomedical professionals, parents of intersex children, and intersex adults from Israel and Germany. Copyright © 2018 Elsevier Ltd.

Although obesity rates are high among Latino children, relatively few studies of parental feeding practices have examined Latino families as a separate group. Culturally-based approaches to measurement development can begin to identify parental feeding practices in specific cultural groups. This study used qualitative and quantitative methods to develop and test the Parental Feeding Practices (PFP) Questionnaire for use with Mexican American parents. Items reflected both parent's use of control over child eating and child-centered feeding practices. In the qualitative phase of the research, 35 Latino parents participated in focus groups. Items for the PFP were developed from focus group discussions, as well as adapted from existing parent feeding practice measures. Cognitive interviews were conducted with 37 adults to evaluate items. In the quantitative phase, mothers and fathers of 174 Mexican American children ages 8-10 completed the PFP and provided demographic information. Anthropometric measures were obtained on family members. Confirmatory factor analyses identified four parental feeding practice dimensions: positive involvement in child eating, pressure to eat, use of food to control behavior, and restriction of amount of food. Factorial invariance modeling suggested equivalent factor meaning and item response scaling across mothers and fathers. Mothers and fathers differed somewhat in their use of feeding practices. All four feeding practices were related to child body mass index (BMI) percentiles, for one or both parents. Mothers reporting more positive involvement had children with lower BMI percentiles. Parents using more pressure to eat had children with lower BMI percentiles, while parents using more restriction had children with higher BMI percentiles. Fathers using food to control behavior had children with lower BMI percentiles. Results indicate good initial validity and reliability for the PFP. It can be used to increase understanding of parental feeding practices, children's eating, and obesity among Mexican Americans, a population at high risk of obesity.

A nonmagnetic differentiated early planetary body

DOE PAGES

Weiss, Benjamin P.; Wang, Huapei; Sharp, Thomas G.; ...

2017-06-19

Paleomagnetic studies of meteorites have shown that the solar nebula was likely magnetized and that many early planetary bodies generated dynamo magnetic fields in their advecting metallic cores.

Paleomagnetic studies of meteorites have shown that the solar nebula was likely magnetized and that many early planetary bodies generated dynamo magnetic fields in their advecting metallic cores. The surface fields on these bodies were recorded by a diversity of chondrites and achondrites, ranging in intensity from several μT to several hundred μT. In fact, an achondrite parent body without evidence for paleomagnetic fields has yet to be confidently identified, hinting that early solar system field generation and the dynamo process in particular may have been common. Here we present paleomagnetic measurements of the ungrouped achondrite NWA 7325 indicating that it last cooled in a near-zero field (<∼1.7 μT), estimated to have occurred at 4563.09 ± 0.26 million years ago (Ma) from Al-Mg chronometry. Because NWA 7325 is highly depleted in siderophile elements, its parent body nevertheless underwent large-scale metal-silicate differentiation and likely formed a metallic core. This makes NWA 7325 the first recognized example of an essentially unmagnetized igneous rock from a differentiated early solar system body. These results indicate that all magnetic fields, including those from any core dynamo on the NWA 7325 parent body, the solar nebula, young Sun, and solar wind, were <1.7 μT at the location of NWA 7325 at 4563 Ma.

The first objective was to determine the prevalence of psychological maladjustment (emotional and behavioural problems), low academic competencies and teasing/social rejection among obese Icelandic children enrolling in a family-based behavioural treatment. A second objective was to explore the degree to which teasing/social rejection specifically contributes to children's psychological adjustment and academic competencies when controlling for other variables, including demographics, children's physical activity, parental depression and life-stress. Participants were 84 obese children (mean body mass index-standard deviation score=3.11, age range=7.52-13.61 years). Height and weight, demographics and measures of children's psychological adjustment, academic competencies, teasing/social rejection and physical activity were collected from children, parents and teachers. Parental depression and life-stress was self-reported. Over half the children exceeded cutoffs indicating concern on at least one measure of behavioural or emotional difficulties. Children endorsed significant levels of teasing/social rejection, with almost half acknowledging they were not popular with same-gender peers. Parent reports of peer problems were even higher, with over 90% of both boys and girls being rated by their parents as having significant peer difficulties. However, rates of low academic competencies as reported by teachers were not different from those of the general population. In regression analyses controlling for other variables, self-reported teasing/social rejection emerged as a significant contributor to explaining both child psychological adjustment and academic competencies. The results indicate that among obese children enrolled in family-based treatment, self-reported teasing/social rejection is quite high and it is associated with poorer psychological adjustment as well as lower academic competencies. Parent reports corroborate the presence of substantial peer difficulties, supporting the need to address peer relations with overweight children both in clinical practice and in public health interventions.

Objective. To assess the feasibility of a parent mentor model of intervention for early childhood obesity using positive deviance-based methods to inform the intervention. Methods. In this pilot, randomized clinical trial, parent-child dyads (age: 2-5) with children whose body mass index (BMI) was ≥95th percentile were randomized to parent mentor intervention or community health worker comparison. The child's height and weight were measured at baseline, after the six-month intervention, and six months after the intervention. Feasibility outcomes were recruitment, participation, and retention. The primary clinical outcome was BMI z-score change. Results. Sixty participants were enrolled, and forty-eight completed the six-month intervention. At baseline, the BMI z-score in the parent mentor group was 2.63 (SD = 0.65) and in the community health worker group it was 2.61 (SD = 0.89). For change in BMI z-score over time, there was no difference by randomization group at the end of the intervention: -0.02 (95% CI: -0.26, 0.22). At the end of the intervention, the BMI z-score for the parent mentor group was 2.48 (SD = 0.58) and for the community health worker group it was 2.45 (SD = 0.91), both reduced from baseline, p < 0.001. Conclusion. The model of a parent mentor clinical trial is feasible, and both randomized groups experienced small, sustained effects on adiposity in an obese, Hispanic population.

Parental obesity moderates the relationship between childhood appetitive traits and weight.

In this study, the independent and combined associations between childhood appetitive traits and parental obesity on weight gain from 0 to 24 months and body mass index (BMI) z-score at 24 months in a diverse community-based sample of dual parent families (n = 213) were examined. Participants were mothers who had recently completed a randomized trial of weight loss for overweight/obese postpartum women. As measures of childhood appetitive traits, mothers completed subscales of the Children's Eating Behavior Questionnaire, including Desire to Drink (DD), Enjoyment of Food (EF), and Satiety Responsiveness (SR), and a 24-h dietary recall for their child. Heights and weights were measured for all children and mothers and self-reported for mothers' partners. The relationship between children's appetitive traits and parental obesity on toddler weight gain and BMI z-score were evaluated using multivariate linear regression models, controlling for a number of potential confounders. Having two obese parents was related to greater weight gain from birth to 24 months independent of childhood appetitive traits, and although significant associations were found between appetitive traits (DD and SR) and child BMI z-score at 24 months, these associations were observed only among children who had two obese parents. When both parents were obese, increasing DD and decreasing SR were associated with a higher BMI z-score. The results highlight the importance of considering familial risk factors when examining the relationship between childhood appetitive traits on childhood obesity.

The objective of this study was to investigate differences in weight perception and self-concept of obese and lean children, and to examine parents' awareness of overweight in themselves and their children. A total of 59 obese patients aged 7-17 years and 49 of their parents from a pediatric obesity out-patient clinic participated and were compared with 96 normal-weight patients and 81 of their parents from a pediatric pulmonary disease out-patient clinic. Children's and parents' self-perception of weight, desire for weight change and weight concerns, children's belief that their desired weight can be achieved, and parents' perception of their child's weight status were assessed using single questionnaire items. Children's self-concept was measured by the Self-Perception Profile for Children. In addition, children drew pictures about themselves and their favorite activity. Obese patients wished to change their weight more frequently (p < 0.001) and had more weight concerns (p < 0.001). Their self-concept was significantly more negative. Physical activities were more common in their drawings than in those of normal-weight peers. Parents of obese children were more frequently overweight or obese themselves (p < 0.001). 35 of them and 73 parents of normal-weight children perceived their own weight realistically. Of the parents with overweight or obese children, 69.4% perceived their own child as overweight and 28.6% as very overweight, whereas 83% of them were obese. Children and adolescents as well as their parents recognize overweight as a health problem. In the majority, weight perception matches real body weight. Most parents at least recognize overweight in their children. Copyright 2010 S. Karger AG, Basel.

Grading the "good" body: a poststructural feminist analysis of body mass index initiatives.

PubMed

Gerbensky-Kerber, Anne

2011-06-01

This article analyzes discourse surrounding Arkansas's legislation requiring public schools to measure students' body mass index (BMI) annually and to send the scores to parents on children's report cards. Using poststructural feminist sensibilities, I explore the tensions experienced by parents, children, educators, and policymakers as this mandate was debated and implemented. The discourse illuminates salient issues about disproportionate disparities in health status that exist in communities with fewer resources, and the potentially unintended gendered consequences of health policies. I explain three dominant threads of discourse: How the economic costs of childhood obesity opened a policy window for the legislation; the presence of tensions between freedom and social control; and how BMI discourses inscribe ideological visions of bodies. Ultimately, the analysis offers insight into the discursive nature of policymaking and how class and gender are implicated in health interventions.

2002-08-01

To compare overweight and non-overweight youth on a selection of self-reported eating, physical activity, dieting, educational, and emotional variables and identify familial factors that serve as protective forces against unhealthy behaviors and psychosocial difficulties among overweight adolescents. Data were taken from a 1996 cross-sectional school-based survey of 9957 adolescents in grades 7, 9, and 11. Based on self-reported heights and weights, respondents were categorized as "overweight" (body mass index) > or =85th percentile or "non-overweight." Student's t-tests were used to compare the non-overweight and overweight sample on the self-reported health-related behaviors and psychosocial variables. Logistic and linear regressions were used to identify familial factors associated with a reduced risk of engaging in unhealthy behaviors and experiencing psychosocial distress. Overweight adolescents reported engaging in significantly more unhealthy behaviors and experiencing more psychosocial distress than their non-overweight peers. Among the overweight youth, higher levels of reported family connectedness and parental expectations and moderate levels of parental monitoring were associated with the lowest levels of unhealthy behaviors and psychosocial distress. Satisfying and developmentally appropriate parent-adolescent relationships are associated with reduced behavioral and psychosocial risk factors associated with overweight during adolescence.

Physician feelings of ineffectiveness and family-related barriers hamper childhood obesity discussions. Physicians desire appealing, time-efficient tools to frame and sensitively address obesity, body mass index, physical activity, nutrition, and portion size. Our university design-led coalition codeveloped tools and games for this purpose. In this feasibility study, we evaluated physician-level counseling of 9- to 12-year-old children and their parents/caretakers using Fitwits MD (Carnegie Mellon University School of Design, Pittsburgh, PA), a brief, structured intervention with flashcards and take-home games. Residency-based physicians in three low- to mid-level socioeconomic urban offices provided self-report data over 8 months through surveys, comment cards, and interviews. We recruited 33 physicians and 93 preadolescents and families. Child-centered key messages resulted in 7-minute conversations, on average. For those physicians who used Fitwits MD, 96% felt improved comfort and competence and 78% noted barrier reduction. Fitwits MD improved residency-based physician self-efficacy and emphasized important health education topics regarding office-based childhood obesity discussions with preadolescents and parents/caretakers.

Secular trends in overweight and obesity among Icelandic adolescents: do parental education levels and family structure play a part?

To investigate whether the secular trend in the increasing prevalence of overweight and obesity among 16- to 20-year-old adolescents in Iceland varied by levels of parental education and family structure. Odds ratios were calculated from repeated population-based, cross-sectional surveys comprising cohorts of 16- to 20-year-old Icelandic adolescents attending junior colleges in 1992 (n=4,922), 2004 (n=11,031), 2007 (n=11,229), and 2010 (n=11,388). Body mass index (BMI) was calculated from self-reported weight and height and categorised as normal weight or overweight and obese, and examined in relation to parental education level and family structure. The odds of being overweight increased by 2.62 and 1.71 for boys and girls respectively over each of the survey time points. The prevalence of overweight and obesity increased across all three subgroups (low, medium, and high) of parental education level. The probability of overweight across all years were consistently the highest for youths with parents in the low-education category followed by middle-educated and high-educated parental background (p<0.05). The gap in overweight and obesity trends between respondents' parental education backgrounds increased over time and was generally explained more by the fathers' education than by the mothers' education (p<0.05). Family structure was not associated with the prevalence of overweight and obesity in our data. Differences in parental levels of education are associated with accelerating trends in prevalence of overweight and obesity among 16- to 20-year-old adolescents in Iceland.

Working with those who have experienced sexual abuse is a complicated matter because such abuse not only involves the violation of the victim's body, but it often generates shame in those involved. This article is based on empirical data from 26 hours of videotaped focus group interviews with 19 adult men and women in a Norwegian incest center who spoke openly of the shame they experienced from sexual abuse as children, parents, and employees. Findings from this study show that shame from sexual abuse can be grouped into seven major categories: (a) family, (b) emotions, (c) body, (d) food, (e) self-image, (f) sex, and (g) therapy.

2013-01-01

Using a sample of low-income children from the Early Childhood Longitudinal Study-Birth Cohort (N ≈ 4,350) and propensity-score weighted regressions, we analyzed children's nutrition, weight, and health care receipt at kindergarten entry, comparing 1) Head Start participants and all non-participants, and 2) Head Start participants and children in prekindergarten, other center-based care, other non-parental care, or only parental care. Overall, we found that compared to all non-participants, Head Start participants were more likely to receive dental checkups but showed no differences in getting medical checkups; they were also more likely to have healthy eating patterns but showed no differences in Body Mass Index (BMI), overweight, or obesity. However, these results varied depending on the comparison group—Head Start participants showed lower BMI scores and lower probability of overweight compared to those in other non-parental care, and the effects on healthy eating and dental checkups differed by comparison group.

Physical inactivity is associated with poor physical fitness and increased body weight. This study examined the relationship between participation in organized sports and overweight as well as physical fitness in primary school children in southern Germany. Height, weight, and various components of physical fitness were measured in 995 children (7.6 ± 0.4 years). Sports participation and confounding variables such as migration background, parental education, parental body weight, and parental sports participation were assessed via parent questionnaire. Multiple logistic regression as well as multivariate analysis of covariance (MANCOVA) was used to determine associations between physical fitness, participation in organized sports, and body weight. Participation in organized sports less than once a week was prevalent in 29.2%, once or twice in 60.2%, and more often in 10.6% of the children. Overweight was found in 12.4% of the children. Children participating in organized sports more than once per week displayed higher physical fitness and were less likely to be overweight (OR  =  0.52, P < 0.01). Even though causality cannot be established, the facilitation of participation in organized sports may be a crucial aspect in public health efforts addressing the growing problems associated with overweight and obesity.

Social coordination in toddler's word learning: interacting systems of perception and action

NASA Astrophysics Data System (ADS)

Pereira, Alfredo; Smith, Linda; Yu, Chen

2008-06-01

We measured turn-taking in terms of hand and head movements and asked if the global rhythm of the participants' body activity relates to word learning. Six dyads composed of parents and toddlers (M=18 months) interacted in a tabletop task wearing motion-tracking sensors on their hands and head. Parents were instructed to teach the labels of 10 novel objects and the child was later tested on a name-comprehension task. Using dynamic time warping, we compared the motion data of all body-part pairs, within and between partners. For every dyad, we also computed an overall measure of the quality of the interaction, that takes into consideration the state of interaction when the parent uttered an object label and the overall smoothness of the turn-taking. The overall interaction quality measure was correlated with the total number of words learned. In particular, head movements were inversely related to other partner's hand movements, and the degree of bodily coupling of parent and toddler predicted the words that children learned during the interaction. The implications of joint body dynamics to understanding joint coordination of activity in a social interaction, its scaffolding effect on the child's learning and its use in the development of artificial systems are discussed.

To evaluate the contributions of weight status, skin tone, peer teasing, and parental appraisals of child's size to self-esteem and psychosocial adjustment in overweight African American children. Overweight to very obese 5- to 10-year-old African American children (N = 117) completed measures of self-esteem, skin tone satisfaction, peer teasing, and body size perception. Caregivers completed the Child Behavior Checklist and rated their child's body size. Overweight was associated with low appearance self-esteem, and body size dissatisfaction with low global self-worth and low appearance self-esteem in children 8 and older. Appearance self-esteem but not global self-worth was lower in girls than boys. Parental perception of child's size as heavier than average was associated with low child appearance self-esteem. Heavier children also had more parental report of behavior and psychosocial problems, but their scores were in the nonclinical range. Child skin tone dissatisfaction was associated with low global self-worth. Weight-related peer teasing was associated with low self-esteem. The relationship between obesity and self-esteem in African American children depends upon age, gender, and children's experiences with teasing and parental evaluation of their size. Other factors, like skin tone satisfaction, contribute to a child's sense of self-worth.

Group IVA irons: New constraints on the crystallization and cooling history of an asteroidal core with a complex history

We report analyses of 14 group IVA iron meteorites, and the ungrouped but possibly related, Elephant Moraine (EET) 83230, for siderophile elements by laser ablation ICP-MS and isotope dilution. EET was also analyzed for oxygen isotopic composition and metallographic structure, and Fuzzy Creek, currently the IVA with the highest Ni concentration, was analyzed for metallographic structure. Highly siderophile elements (HSE) Re, Os and Ir concentrations vary by nearly three orders of magnitude over the entire range of IVA irons, while Ru, Pt and Pd vary by less than factors of five. Chondrite normalized abundances of HSE form nested patterns consistent with progressive crystal-liquid fractionation. Attempts to collectively model the HSE abundances resulting from fractional crystallization achieved best results for 3 wt.% S, compared to 0.5 or 9 wt.% S. Consistent with prior studies, concentrations of HSE and other refractory siderophile elements estimated for the bulk IVA core and its parent body are in generally chondritic proportions. Projected abundances of Pd and Au, relative to more refractory HSE, are slightly elevated and modestly differ from L/LL chondrites, which some have linked with group IVA, based on oxygen isotope similarities. Abundance trends for the moderately volatile and siderophile element Ga cannot be adequately modeled for any S concentration, the cause of which remains enigmatic. Further, concentrations of some moderately volatile and siderophile elements indicate marked, progressive depletions in the IVA system. However, if the IVA core began crystallization with ˜3 wt.% S, depletions of more volatile elements cannot be explained as a result of prior volatilization/condensation processes. The initial IVA core had an approximately chondritic Ni/Co ratio, but a fractionated Fe/Ni ratio of ˜10, indicates an Fe-depleted core. This composition is most easily accounted for by assuming that the surrounding silicate shell was enriched in iron, consistent with an oxidized parent body. The depletions in Ga may reflect decreased siderophilic behavior in a relatively oxidized body, and more favorable partitioning into the silicate portion of the parent body. Phosphate inclusions in EET show Δ 17O values within the range measured for silicates in IVA iron meteorites. EET has a typical ataxitic microstructure with precipitates of kamacite within a matrix of plessite. Chemical and isotopic evidence for a genetic relation between EET and group IVA is strong, but the high Ni content and the newly determined, rapid cooling rate of this meteorite show that it should continue to be classified as ungrouped. Previously reported metallographic cooling rates for IVA iron meteorites have been interpreted to indicate an inwardly crystallizing, ˜150 km radius metallic body with little or no silicate mantle. Hence, the IVA group was likely formed as a mass of molten metal separated from a much larger parent body that was broken apart by a large impact. Given the apparent genetic relation with IVA, EET was most likely generated via crystal-liquid fractionation in another, smaller body spawned from the same initial liquid during the impact event that generated the IVA body.

Overweight and obesity are steadily increasing worldwide with the greatest prevalence occurring in high-income countries. Many factors influence body mass index (BMI); however multiple influences assessed in families and individuals are rarely studied together in a prospective design. Our objective was to model the impact of multiple influences at the child (low birth weight, history of maltreatment, a history of childhood mental and physical conditions, and school difficulties) and family level (parental income and education, parental mental and physical health, and family functioning) on BMI in early adulthood. We used data from the Ontario Child Health Study, a prospective, population-based study of 3,294 children (ages 4-16 years) enrolled in 1983 and followed up in 2001 (N = 1,928; ages 21-35 years). Using multilevel models, we tested the association between family and child-level variables and adult BMI after controlling for sociodemographic variables and health status in early adulthood. At the child level, presence of psychiatric disorder and school difficulties were related to higher BMI in early adulthood. At the family level, receipt of social assistance was associated with higher BMI, whereas family functioning, having immigrant parents and higher levels of parental education were associated with lower BMI. We found that gender moderated the effect of two risk factors on BMI: receipt of social assistance and presence of a medical condition in childhood. In females, but not in males, the presence of these risk factors was associated with higher BMI in early adulthood. Overall, these findings indicate that childhood risk factors associated with higher BMI in early adulthood are multi-faceted and long-lasting. These findings highlight the need for preventive interventions to be implemented at the family level in childhood.

This study sought to assess differences in attraction to physical activity, perceived physical competence and parental socialization influences across gender, body mass index and socioeconomic status in Portuguese children. Cross-sectional study. 683 children, aged 8-10 years, from elementary schools were participants. Attraction to physical activity, perceived physical competence, parental socialization influences and socioeconomic status were assessed via standardized questionnaires. The prevalence of overweight and obesity was calculated using body mass index, based on the international cut-off points. MANOVA and ANOVA models were conducted. Boys reported greater enjoyment of games and sports participation than did girls. Boys and normal-weight children perceived themselves as being more successful and physically competent than did girls and obese children. Normal-weight girls enjoyed participation in vigorous physical activity more than did overweight and obese girls. Obese children felt less accepted by their peers in games and sports than did normal-weight and overweight children. High and medium socioeconomic status children perceived physical activity participation as of greater importance than did low-socioeconomic status children. High-socioeconomic status girls reported greater liking of the exertional aspects of physical activity compared to low socioeconomic status girls. High socioeconomic status children were more likely to perceive their parents as positive role models and perceived that they had greater enjoyment of physical activity than did lower socioeconomic status children. These results suggest that physical activity promotion interventions should focus on girls, obese children and lower socioeconomic status children as these individuals tend to have lower levels of attraction to physical activity, lower perceived physical competence and less parent physical activity support, which puts them at greater risk of being physically inactive.

Body image and its relation to obesity for Pacific minority ethnic groups in New Zealand: a critical analysis.

PubMed

Teevale, Tasileta

2011-03-01

The stimulus behind most of the early investigations into Pacific or Polynesian peoples' body image, particularly those that looked to compare with Western or Westernised groups, is the assumption that Pacific peoples valued and therefore desired very large bodies, and in relation to obesity-risk, this is a problematic cultural feature to have. This may be driven by popular anecdotes which are captured in the title of one such study "Do Polynesians still believe that big is beautiful?" To the author's knowledge, no research in Pacific peoples' body image has been conducted in the New Zealand (NZ) context by Pacific researchers. This study makes a contribution to the literature gap and more importantly through an emic viewpoint. A critique of the current literature is provided below which calls into question the initial catalyst behind earlier investigations which have led to the perpetuation of particular types of body image research for Pacific groups. Using mixed-methods, the specific objective of this study was to describe the behaviours, beliefs and values of Pacific adolescents and their parents, that are related to body image. A self-completion questionnaire was administered to 2495 Pacific students who participated in the New Zealand arm of the Obesity Prevention In Communities (OPIC) project. Sixty-eight people (33 adolescents and 35 parents) from 30 Pacific households were interviewed in the qualitative phase of the study. This study found Pacific adolescents and their parents did not desire obesity-sized bodies but desired a range of average-sized bodies that met their Pacific-defined view of health. It is not clear whether body image research makes any meaningful contribution to obesity prevention for Pacific people, given the cultural-bounded nature of the concept "body image" which sits communication and understanding between obesity interventionists and all healthcare workers generally and Pacific communities. For obesity interventions to be acceptable and useful for Pacific people, they must be responsive to the beliefs and desires of these communities.

Shock pressure recorded in Yamato (Y)-790729, classified as L6 type ordinary chondrite, was evaluated based on high-pressure polymorph assemblages and cathodoluminescence (CL) spectra of maskelynite. The host-rock of Y-790729 consists mainly of olivine, low-Ca pyroxene, plagioclase, metallic Fe-Ni, and iron-sulfide with minor amounts of phosphate and chromite. A shock-melt vein was observed in the hostrock. Ringwoodite, majorite, akimotoite, lingunite, tuite, and xieite occurred in and around the shock-melt vein. The shock pressure in the shock-melt vein is about 14-23 GPa based on the phase equilibrium diagrams of high-pressure polymorphs. Some plagioclase portions in the host-rock occurred as maskelynite. Sixteen different CL spectra of maskelynite portions were deconvolved using three assigned emission components (centered at 2.95, 3.26, and 3.88 eV). The intensity of emission component at 2.95 eV was selected as a calibrated barometer to estimate shock pressure, and the results indicate pressures of about 11-19 GPa. The difference in pressure between the shock-melt vein and host-rock might suggest heterogeneous shock conditions. Assuming an average shock pressure of 18 GPa, the impact velocity of the parent-body of Y-790729 is calculated to be 1.90 km s-1. The parent-body would be at least 10 km in size based on the incoherent formation mechanism of ringwoodite in Y-790729.

Parental caregiving is critical for the survival of our young and continuation of our species. In humans, visual and auditory signals from offspring have been shown to be potent facilitators of parenting. However, whether odors emitted by our young also influence human parenting remains unclear. To explore this, we conducted a series of questionnaire surveys targeting parents with children under 6 years old. First, we collected episodes on experiencing odors/sniffing various parts of a child's body (n = 507). The prevalence of experiencing events described in those episodes was examined in a separate survey (n = 384). Based on those results, the Child Odor in Parenting scale (COPs) was developed, and subsequently used in the main survey (n = 888). We found COPs to have adequate content validity, concurrent validity, and reliability. Responses to the COPs demonstrated that parents, especially mothers with infants, are aware of odors from their offspring, and actively seek them in daily child-rearing. The factor structure and content of the COPs items indicated that child odors have both affective and instrumental roles. Affective experiences induce loving feeling and affectionate sniffing, while instrumental experiences pertain to specific hygienic needs. The head was the most frequent source of affective experiences, and the child's bottom of instrumental. Each was experienced by more than 90% of the mothers with a child below 1 year of age. Affective experiences significantly declined as the child grew older, possibly associated with the decline of physical proximity between parents and child. This age-related decline was not prominent for instrumental experiences, except for the bottom, which significantly declined after 3 years of age. The present findings suggest that child odors play roles in human parenting, and that their nature and significance change during the course of a child's development.

Objective Little is known about whether siblings have similar or different eating behaviors or whether parents tailor their feeding practices to different siblings. The main objectives of this study were to examine similarities and differences in child eating behaviors and parental feeding practices with siblings and to examine whether child eating behaviors or parental feeding practices differ depending on sibling concordant (i.e., both siblings overweight or healthy weight) or discordant (i.e., one sibling overweight and one sibling healthy weight) weight status. Design Cross-sectional, mixed-methods study. Setting In-home visits were conducted by research staff. Surveys were conducted with parents and anthropometry was collected on parents and siblings. Subjects Children (n=88) ages 6–12 years (mean=9; sd=2), their parents (mean age=34; sd=7), and near-age siblings (mean age=9; sd=4) from diverse racial/ethnic and low-income households participated in the current study. Results Results indicated that siblings with higher body mass index engaged in higher levels of emotional eating compared to siblings with lower BMI. Additionally, results indicated that when families had sibling dyads who were discordant on weight status, the sibling who was overweight had higher food enjoyment and lower levels of food satiety. Additionally, within discordant weight status siblings, parents were more likely to use restrictive feeding practices with siblings who were overweight and pressure-to-eat and encouragement-to-eat feeding practices with siblings who were healthy weight. Conclusions Family-based childhood obesity interventions may need to assess for sibling weight status when researching the home environment and intervene with parents to avoid using restriction or pressure-to-eat feeding practices when siblings are discordant on weight status.

This pilot study investigated the impact of a parent-child dyad cooking intervention on reducing eating dinner away from home. Eating away from home often results in consumption of energy-dense, nutrient-poor foods that can contribute to excess energy consumption in children. A pre-post design to evaluate a 10-week cooking intervention on reducing eating dinner away from home, energy intake, and improving diet quality was implemented. The intervention was delivered at an instructional kitchen on a university campus and assessments were completed at a children's academic medical center. Subjects included six parent-child dyads whom reported eating dinner away from home ≥3 times/week and in which the parent was overweight based on their body mass index (BMI) of ≥25 kg/m(2). Parents were a mean age of 34.7 (SD = 3.9) years, and children were a mean age of 8.7 (SD = 2.0) years. Two-thirds of parents self-identified themselves and their children as White. Results showed the proportion of dinners consumed by parent-child dyads away from home significantly decreased (F (1,161) = 16.1, p < 0.05) from 56% at baseline to 25% at post-treatment. Dyad cholesterol intake at dinner also significantly decreased over time; however, changes in energy intake, total fat, saturated fat, and sodium at dinner were not significant. A large effect size was found for changes in parent ratings of enjoyment of cooking between baseline and post-treatment. A cooking intervention that involves parent-child dyads and incorporates behavior management strategies and nutrition education may be an innovative obesity prevention intervention.

Music therapists working with families address relationship and interpersonal communication issues. Few controlled studies exist in the literature but a growing body of documented practice is emerging. This study makes a contribution by documenting how music therapy supports mutuality and reciprocity in parent-child interactions. This study investigated mutually responsive orientation (MRO) behaviors of young children (aged 3-5) and their family members during music therapy. Participants were 4 families with low income and history of maternal depression as common risk factors. Data were collected by videotaping sessions, creating field notes and analytic memos, conducting parent interviews and reviewing parent journals. A cross-case analysis using MRO theory as a conceptualizing framework was used for the purpose of data reduction. Greeting and farewell rituals, and the flexibility of music-based therapeutic applications facilitated development of coordinated routines. Therapist's actions (e.g., encouraging and modeling musical interactions) and bidirectional parent-child actions (e.g., joint attention, turn-taking, being playful) facilitated harmonious communication. Behaviors promoting mutual cooperation were evident when adults attempted to scaffold a child's participation or when children sought comfort from parents, engaged in social referencing and made requests that shaped the direction of the session. The novelty of musical tasks captivated attention, increasing impulse inhibition. Parent actions (e.g., finding delight in watching their child participate, acting silly) and parent-child interactions (e.g., play exploration, shared excitement, cuddling) contributed to positive emotional ambiance. Music therapy assisted development of MRO within parent-child dyads by providing opportunities to rehearse adaptive ways of connecting with each other. Results of this study may serve as an archetypal model guiding clinical treatment planning.

Parents' employment status is frequently cited as a possible predictor of child weight status. Despite the importance of the topic, only a few studies have been conducted. No longitudinal studies have been conducted in the United States. A cohort of 1201 girls from the Trial of Activity for Adolescent Girls was used. Height, weight, and percent body fat (PBF) were measured at the 6th and 8th grades. Parents' employment status (measured at 6th grade) was categorized into working full time (reference), part time, unemployed, working or staying at home, and don't know. Mixed-model regression was used to reflect the hierarchical design of our study and adjusted for age, race, parents' education level, free or reduced-price school lunch status, and living arrangement. Girls whose mothers worked part time or stayed at home had a decreased risk of excess weight gain [relative risk (RR) = 0.94, 95% confidence interval (CI) 0.88, 1.00; RR = 0.89, 95% CI 0.79, 1.00, respectively] compared to girls whose mothers worked full time. Girls whose fathers were unemployed had a moderately increased risk of excess weight gain (RR = 1.13, 95% CI 1.00, 1.26) compared to girls whose fathers worked full time. Having an unemployed mother or part-time or stay-at-home father was not associated with excess weight gain. Parents' employment status was not associated with excess PBF gain. Our findings suggest that the availability of the mother has a greater influence on the weight of the daughter than the availability of the father. There is a need for a better understanding of how parents' employment status influences excess weight gain in adolescent girls.

To determine if differences existed in mothers' and fathers' perceptions of their sons' weight, controlling child-feeding practices (ie, restriction, monitoring, and pressure to eat), and parenting styles (ie, authoritarian, authoritative, and permissive) by their sons' body mass index (BMI). One person (L.S.B.) interviewed mothers and boys using validated questionnaires and measured boys' weight and height; fathers completed questionnaires independently. Subjects were white, preadolescent boys and their parents. Boys were grouped by their BMI into an average BMI group (n=25; BMI percentile between 33rd and 68th) and a high BMI group (n=24; BMI percentile > or = 85th). Multivariate analyses of variance and analyses of variance. Mothers and fathers of boys with a high BMI saw their sons as more overweight (mothers P=.03, fathers P=.01), were more concerned about their sons' weight (P<.0001, P=.004), and used pressure to eat with their sons less often than mothers and fathers of boys with an average BMI (P<.0001, P<.0001). In addition, fathers of boys with a high BMI monitored their sons' eating less often than fathers of boys with an average BMI (P=.006). No differences were found in parenting by boys' BMI groups for either mothers or fathers. More controlling child-feeding practices were found among mothers (pressure to eat) and fathers (pressure to eat and monitoring) of boys with an average BMI compared with parents of boys with a high BMI. A better understanding of the relationships between feeding practices and boys' weight is necessary. However, longitudinal research is needed to provide evidence of causal association.
