Children's health and their mothers’ risk of divorce or separation

Abstract

The purpose of this study is to determine how children's health conditions are related to their mothers’ risk of divorce or separation. The study is based on data from over 7,000 children born to once‐married mothers identified in the 1988 Child Health Supplement to the National Health Interview Survey. The effects of 15 childhood health conditions on the mothers’ risk of divorce are estimated with Cox's proportional hazard models. Controlling for demographic, marital, and reproductive measures, we find that mothers’ prospects for divorce are affected both positively or negatively by their children's health status, depending on the type of childhood condition and, in the case of low birth weight children, timing within the marriage. Women whose children have congenital heart disease, cerebral palsy, are blind, or had low birth weight appear to have higher risks of marital disruption than mothers of healthy children. In contrast, mothers whose children have migraines, learning disabilities, respiratory allergies, missing/deformed digits or limbs, or asthma have somewhat lower rates of divorce.     

Influence of parents' eating behaviors and child feeding practices on children's weight status

Objective : To investigate the effects of mothers’ and fathers’ eating behaviors, child feeding practices, and BMI on percentage body fat and BMI in their children. Research Methods and Procedures : Four hundred fifty‐eight parents (239 mothers, 219 fathers) were asked to complete two questionnaires: the Three‐Factor Eating Questionnaire and the Child Feeding Questionnaire, which measure dimensions of parent eating behavior and child feeding practices, respectively. Parent BMI was calculated from self‐reported height and weight; children's measures included BMI and percentage fat assessed by DXA. Regression analyses were used to analyze relationships between parents’ BMI and questionnaire scores and children's weight status. Results : One hundred forty‐three mothers and 68 fathers returned questionnaires, representing parents of 148 children 3 to 5 years old (78 boys). Children's weight was related to mothers’ BMI, but not fathers’. Girls had a greater BMI if either parent reported being overweight as a child, and both girls and boys were likely to be overweight if their mothers believed they had risky eating habits (fussiness, eating too much, etc.). Girls with fathers who were more controlling had a higher percentage fat; these fathers were also more concerned about their daughters’ future health. Discussion : Mothers exert a strong influence over their children's weight and seem to be more concerned about their children's eating behaviors; however, fathers play a role in imposing child feeding practices. Gender bias may be present in child feeding, as suggested by dissimilar effects of parent practices on the weight status of girls vs. boys. Fathers should be included in future studies analyzing parent feeding practices and children's weight outcome.     

Companion Animals and other Factors Affecting Young Children's Development

ABSTRACT

This study focuses on three factors presumed to affect young children's development: their age, the quality of their home environments, and the child-pet relationship. Three sets of analyses are presented: effects associated with pet ownership (pet presence), effects associated with the strength of the child-pet relationship, and the combined effects of age, home environment, and the child-companion animal relationship. This study includes both a parent survey (n = 88) and in-home assessments (n = 44) of the three- to six-year-old children. The analyses support the hypothesis that normal preschool children's intellectual, motor, and social development is associated with the presence of a companion animal and increases with their age, the quality of their home environment, and their relationship with a companion animal. While the children's age and the quality of their home environments were associated with measures of the children's cognitive, motor, and social development, the companion animal effect was limited to the young children's social development including their empathy for other children.     

Predictors of accurate maternal perception of their preschool child's weight status among Hispanic WIC participants

Childhood obesity is a growing problem in the United States. Parental perception of their children's weight status is a key factor that needs to be considered when developing prevention programs for preschool children. Using a randomly selected sample of participants of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Los Angeles County, we assessed accuracy of maternal perceptions of their children's weight status by comparing children's weight classification to the mothers' response to the question “Do you consider your child to be overweight, underweight or about right weight for (his) (her) height?” Additionally, we identified possible predictors of accurate maternal perception of their children's weight status by conducting a logistic regression model with child's gender, child's birth weight, maternal age, maternal BMI, maternal education, maternal acculturation level, and maternal language preference as potential predictors. Almost all mothers in the study classified their overweight or obese child as being about the right weight (93.6% and 77.5% of mothers, respectively). Maternal BMI and child's birth weight were the only predictors of maternal perception of their child's weight. Both were negatively associated with accuracy, with higher maternal BMI and higher infant birthweight associated with less accurate maternal perception of child weight. Parents need to be educated on the importance of childhood obesity and how to identify if their children are overweight or obese. If parents fail to recognize that their overweight child is overweight, then it is unlikely that they will recognize that interventions targeting obesity are relevant to their families.     

The extended relationship between child cardiovascular risks and academic performance measures

Objective: To examine the relationship between children's overweight status and other cardiovascular risk fitness factors and academic performance among fifth‐grade students. Research Methods and Procedures: Using a sample of 968 fifth‐grade students (50.7% boys; mean age = 10.6 years), children's cardiovascular risks (BMI, blood pressure, acanthosis nigricans) and fitness measures were compared with their mean group performance scores across four subscales (mathematics, reading/language arts, science, and social studies) of a statewide standardized academic performance test. Results: Of this sample, 39% were either at risk for being overweight or were already overweight; slightly over one half were of normal weight. Initial findings revealed a significant relationship between children's weight category and their reading/language arts, mathematics, and science test scores even after controlling for a proxy of socioeconomic status. When additional cardiovascular risk and fitness measures were included in the model, however, children's BMI status had no association. Instead, a composite fitness index, children's blood pressure, sex, and proxy of socioeconomic status were significantly associated with children's academic test scores. Discussion: This study expanded our understanding of the connection between children's overweight risks and academic performance by examining the impact of other cardiovascular risk factors such as high blood pressure and measures of fitness. These findings support the development and implementation of childhood cardiovascular risk surveillance programs that evaluate not only children's overweight risks but also their fitness, risk for type 2 diabetes, and/or high blood pressure by showing a relationship between some of these risks and children's academic test performance.     

“Gift Giving” by Wild Bottle nose Dolphins (Tursiops sp.) to Humans at a Wild Dolphin Provisioning Program,Tangalooma, Australia

ABSTRACT

While there is increasing interest in the impact of animal interactions upon children's wellbeing and attitudes, there has been less attention paid to the specific characteristics of the animals that attract and engage children. We used a within-subjects design to explore how differences in animal features (such as their animacy, size, and texture) impacted upon pre-school children's social and emotional responses. This study examined pre-schoolers' interactions with two animal-like robots (Teksta and Scoozie), two insect types (stick insects and hissing cockroaches) and a dog (Teasel, a West Highland Terrier). Nineteen preschool participants aged 35–57 months were videoed while interacting with the experimenter, a peer, and each stimulus (presented individually). We used both verbal and nonverbal behaviors to evaluate interactions and emotional responses to the stimuli and found that these two measures could be incongruent, highlighting the need for systematic approaches to evaluating children's interactions with animals. We categorized the content of children's dialogues in relation to psychological and biological attributes of each stimulus and their distinctions between living and non-living stimuli; the majority of comments were biological, with psychological terms largely reserved for the dog and mammal-like robot only. Comments relating to living qualities revealed ambiguity towards attributes that denote differences between living and non-living creatures. We used a range of nonverbal measures, including willingness to approach and touch stimuli, rates of self-touching, facial expressions of emotion, and touch to others. Insects (hissing cockroaches and stick insects) received the most negative verbal and nonverbal responses. The mammal-like robot (rounded, fluffy body shape, large eyes, and sympathetic sounds) was viewed much more positively than its metallic counterpart, as was the real dog. We propose that these interactions provide information on how children perceive animals and a platform for the examination of human socio-emotional and cognitive development more generally. The children engaged in social referencing to the adult experimenter rather than familiar peers when uncertain about the stimuli presented, suggesting that caregivers have a primary role in shaping children's responses to animals.     

Is Parental Control over Children's Eating Associated with Childhood Obesity? Results from a Population‐Based Sample of Third Graders

Objective: Identifying parental behaviors that influence childhood obesity is critical for the development of effective prevention and treatment programs. Findings from a prior laboratory study suggest that parents who impose control over their children's eating may interfere with their children's ability to regulate intake, potentially resulting in overweight. These findings have been widely endorsed; however, the direct relationship between parental control of children's intake and their children's degree of overweight has not been shown in a generalized sample. Research Methods and Procedures: This study surveyed 792 third‐grade children with diverse ethnic and socioeconomic backgrounds from 13 public elementary schools. Parental control over children's intake was assessed through telephone interviews using a state‐of‐the‐art instrument, and children were measured for height, weight, and triceps skinfold thickness. Results: Counter to the hypothesis, parental control over children's intake was inversely associated with overweight in girls, as measured by body mass index, r = ?0.12, p < 0.05, and triceps skinfolds, r = ?0.11, p < 0.05. This weak relationship became only marginally significant when controlling for parents’ perceptions of their own weight, level of household education, and children's age. No relationship between parental control of children's intake and their children's degree of overweight was found in boys. Discussion: Previous observations of the influence of parental control over children's intake in middle‐class white families did not generalize to 8‐ to 9‐year‐olds in families with diverse socioeconomic and ethnic backgrounds. The present findings reveal a more complex relationship between parental behaviors and children's weight status.     

A Latent Class Analysis of Bullies,Victims and Aggressive Victims in Chinese Adolescence: Relations with Social and School Adjustments

This study used the latent class analysis (LCA) to identify and classify Chinese adolescent children''s aggressive behaviors. It was found that (1) Adolescent children could be divided into four categories: general children, aggressive children, victimized children and aggressive victimized children. (2) There were significant gender differences among the aggressive victimized children, the aggressive children and the general children. Specifically, aggressive victimized children and aggressive children had greater probabilities of being boys; victimized children had equal probabilities of being boys or girls. (3) Significant differences in loneliness, depression, anxiety and academic achievement existed among the aggressive victims, the aggressor, the victims and the general children, in which the aggressive victims scored the worst in all questionaires. (4) As protective factors, peer and teacher supports had important influences on children''s aggressive and victimized behaviors. Relative to general children, aggressive victims, aggressive children and victimized children had lower probabilities of receiving peer supports. On the other hand, compared to general children, aggressive victims had lower probabilities of receiving teacher supports; while significant differences in the probability of receiving teacher supports did not exist between aggressive children and victimized children.     

Dreaming in Spain: parental determinants of immigrant children's ambition

We examine determinants of educational and occupational aspirations and expectations among children of immigrants in Spain on the basis of a unique data set that includes statistically representative data for foreign-origin secondary students in Madrid and Barcelona plus a sample of one-fourth of their parents. Independently collected data for both generations allow us to establish effects of parental characteristics on children's orientations without the confounding potential inherent in children's reports about parents. We analyse first determinants of parental ambition and, through a series of stepwise regressions, the effects of these goals and other parental and family characteristics on children's aspirations and expectations. A structural equations model synthesizes the results of the analysis. The model confirms predictions from the research literature, especially those based on the Wisconsin status attainment model, but rejects others, including the predicted significance of private versus public school attendance. Parental ambition, knowledge of Spanish by parents and children, gender and children's age are major determinants of youths' educational and occupational goals. These results have direct implications for policy; these are discussed in the conclusion.     

Effects of the built environment on childhood obesity: The case of urban recreational trails and crime

We study the effects of urban environment on childhood obesity by concentrating on the effects of walking trails and crime close to children's homes on their BMI and obesity status. We use a unique dataset, which combines information on recreational trails in Indianapolis with data on violent crimes and anthropomorphic and diagnostic data from children's clinic visits between 1996 and 2005. We find that having a trail near a home reduces children's weight. However, the effect depends on the amount of nearby violent crimes. Significant reductions occur only in low crime areas and trails could have opposite effects on weight in high crime areas. These effects are primarily among boys, older children, and children who live in higher income neighborhoods. Evaluated at the mean length of trails this effect for older children in no crime areas would be a reduction of 2 lb of the body weight. Falsification tests using planned trails instead of existing trails, show that trails are more likely to be located in areas with heavier children, suggesting that our results on effects of trails represent a lower bound.     

Children's ideas of animals' internal structures

Children's understanding about animal internal structure can be affected by several factors which are poorly understoodby teachers. We conducted a large sample study (n=702) of children aged 6–16 years (Grades 1-9) examining children's responses to animals of various size, species and dimensions (2D and 3D objects), and exploring factors which might affect the development of their knowledge. Each child made a drawing of what they thought was inside a specimen animal. We found that using 2D representations of an animal negatively affected the content of children drawings.The effect of animalsize was shown only in children's understanding of skeletons, but not organ systems. The effect of animal species showedclear significant effect of children's ideas on both organ systems and skeleton. Investigation showed that parents' education level, children's experiences with animal-rearing and age significantly affected their scores from organ system. Surprisingly, school books were most frequently cited as sources of children's knowledge rather than their own experience, or information from the internet, encyclopaedias, television or parents.     

Population level differences in adult body mass emerge in infancy and early childhood: Evidence from a global sample of low and lower‐income countries

Many studies have linked measures of adult body shape and mass in ancient and contemporary populations to ecogeographical variables such as temperature and latitude. These results tend to support Bergmann's rule, which posits that bodies will be relatively less slender for their height in colder climates and more slender in warmer climates. Less well explored is the ontogeny of these population‐level differences. Here we use data on infants and children from 46 low and lower income countries to test whether children's weight for height is associated with measures of temperature and latitude. We also test the hypothesis that children living in areas with greater pathogen prevalence will be lighter for their height because of life history trade‐offs between investment in immune function and growth. Finally, we test whether population specific adult body mass predicts infant and child body mass, and whether this is independent of ecogeographical variables. Our results show that maximum monthly temperature explains 17% of children's weight for height while adult population‐level body mass explains ～44% (Table 5 ). The measures of pathogen prevalence explain little of the variation in children's body shape (8%; P > 0.05). Our results suggest that population differences are consistent with Bergmann's rule but parental body shape explains more variance. Moreover, these population‐level differences arise early in development, suggesting that any possible environmental influences occur in utero and/or result from epigenetic or population genetic differences.

Observable Weight Distributions and Children's Individual Weight Assessment

Social networks theory suggests obesity is “contagious” within peer groups in that known friends highly influence weight. On the other hand, an alternative model suggests that observable weight distributions affect perception of one's own obesity level. We examine whether the BMI levels of the most obese classmates in the individual student's grade by gender is positively associated with “under‐assessment” of obesity and overweight (i.e., independently measured obesity or overweight, but subjective self‐assessment of normal weight). The data are the 2004–2005 School Physical Activity and Nutrition III (SPAN), a stratified, multistage probability sample of 4th, 8th, and 11th grade public school children in Texas. We used logistic regression to test whether the gender‐specific 85th percentile BMI level within the individual student's grade at their school is positively associated with “under‐assessment” of obesity and overweight. The results show that students are much more likely to under‐assess their own weight if the gender‐specific 85th percentile BMI level is higher in their grade at their school. These data suggest that observable weight distributions play a key role in the obesity epidemic.     

Associations between multiple measures of parental feeding and children's adiposity in United Kingdom preschoolers

Objective: Research into the association between parental control over feeding and children's adiposity has produced inconclusive results. Some studies have found parental control to be associated with unhealthy food choices and disordered intake regulation, whereas others have found favorable or null associations between control and adiposity. This study hypothesized that variability in measures of parental feeding could contribute to these discrepancies. Scales from a range of existing parental feeding questionnaires were used together, in the same large sample of children, to examine associations with adiposity. Research Methods and Procedures: Associations between scores on scales from three published parental feeding questionnaires [Child Feeding Questionnaire (CFQ); Preschooler Feeding Questionnaire (PFQ); and Parental Feeding Style Questionnaire (PFSQ)] and children's BMI z‐scores, calculated from measured heights and weights, were examined in a socioeconomically diverse sample of 439 parents and their 3‐ to 5‐year‐old children. Results: Higher scores on CFQ Pressure to Eat and PFQ Pushing the Child to Eat More were significantly associated with lower BMI z‐score, while PFSQ Prompting to Eat, CFQ Restriction, PFSQ Instrumental Feeding, and PFSQ Emotional Feeding were unassociated with BMI z‐score. Discussion: These results suggest that parents of leaner children are more likely to encourage their children to eat. Other feeding strategies seemed to have negligible relationships with children's BMI z‐scores at this stage. Longitudinal and genetically informed designs are needed to clarify the causal pathways between parental feeding and children's adiposity.     

Influence of Body Composition on the Accuracy of Reported Energy Intake in Children

Objective: Mis‐reporting dietary intake is a substantial barrier to understanding the role of dietary behavior in disease. Work with adults indicates that heavier individuals under‐report dietary intake and that under‐reporting may be macronutrient‐specific. Whether weight status and macronutrient intake influence the accuracy of dietary reports among children, however, is less clear. This research evaluated children's dietary reporting accuracy as a function of their relative weight, body composition, and macronutrient intake. Research Methods and Procedures: Participants included 146 4‐ to 11‐year‐old children. Reported energy intake was determined by interviewing children in the presence of parents, using three multiple pass, 24‐hour recalls. Children were classified as having had an under‐reported, accurately reported, or over‐reported dietary intake relative to total energy expenditure, as measured by doubly labeled water. Reporting accuracy was examined as a function of children's body weight, body composition (using dual energy x‐ray absorptiometry), and macronutrient intake. Results: Average reported intake was, on average, 14% greater than children's estimated expenditure (p < 0.01). Reporting accuracy varied as a function of children's relative weight and body composition; under‐reporting tended to occur among heavier children, having the highest body fat content (p < 0.0001) and relative weight (p < 0.0001). Discussion: These findings suggest that weight status influences the accuracy of dietary reports made by children and their parents. More research is needed to address possible psychological and social factors that introduce bias in reporting children's dietary data.     

Psychological status and weight-related distress in overweight or at-risk-for-overweight children

Objective: To associate psychological status, weight‐related distress, and weight status during childhood in overweight or at‐risk‐for‐overweight children. Research Methods and Procedures: We associated self‐report of depression, trait anxiety, and weight‐related distress (body size dissatisfaction and weight‐related peer teasing after controlling for the effects of weight) in 164 children (black 35%; age 11.9 ± 2.5 years; girls 51%) who were overweight or at‐high‐risk‐for‐overweight and were not seeking weight loss. Results: Overall, heavier children reported more psychological and weight‐related distress. Black children reported more anxiety and body size dissatisfaction than white children, despite equivalent weights. However, psychological distress was not significantly associated with weight in white children. Girls reported more weight‐related distress than boys. Depression was associated with weight‐related teasing in all predictive models, except in the model using only black subjects. Trait anxiety was associated with report of peer teasing when using all subjects. Depression was also significantly associated with children's report of body size dissatisfaction in models using all subjects, only girls, or white subjects, but not in analyses using only boys or black subjects. For boys peer teasing was associated with body size dissatisfaction. In models including only black children, depression and trait anxiety were not significantly associated with either report of peer teasing or body size dissatisfaction. Discussion: Regardless of race or sex, increasing weight is associated with emotional and weight‐related distress in children. However, associations of psychological status, weight, and weight‐related distress differ for girls and boys, and for black and white children.     

Differences in nutritional status between rural and urban Yucatec Maya children: The importance of early life conditions

Early-life conditions shape childhood growth and are affected by urbanization and the nutritional transition. To investigate how early-life conditions (across the “first” and “second” 1000 days) are associated with rural and urban children's nutritional status, we analyzed anthropometric data from Maya children in Yucatan, Mexico. We collected weight, height and triceps skinfold measures, then computed body mass and fat mass indices (BMI/FMI), in a cross-sectional sample of 6-year-olds (urban n = 72, rural n = 66). Demographic, socioeconomic and early-life variables (birthweight/mode, rural/urban residence, household crowding) were collected by maternal interview. We statistically analyzed rural-urban differences in demographic, socioeconomic, early-life, and anthropometric variables, then created linear mixed models to evaluate associations between early-life variables and child anthropometric outcomes. Two-way interactions were tested between early-life variables and child sex, and between early-life variables and rural-urban residence. Results showed that rural children were shorter-statured, with lower overweight/obesity and cesarean delivery rates, compared to urban children. Household crowding was a negative predictor of anthropometric outcomes; the strongest effect was in boys and in urban children. Birthweight positively predicted anthropometric outcomes, especially weight/BMI. Birth mode was positively (not statistically) associated with any anthropometric outcome. Cesarean delivery was more common in boys than in girls, and predicted increased height in urban boys. In conclusion, urbanization and household crowding were the most powerful predictors of Maya 6-year-old anthropometry. The negative effects of crowding may disproportionately affect Maya boys versus girls and urban versus rural children. Early-life conditions shape Maya children's nutritional status both in the “first” and “second” 1000 days.     

Family ties and child obesity in Italy

This paper examines the impact of overweight family members on weight outcomes of Italian children aged 6–14 years. We use an original dataset matching the 2012 cross sections of the Italian Multipurpose Household Survey and the Household Budget Survey. Since the identification of within-family peer effects is known to be challenging, we implement our analysis on a partially identified model using inferential procedures recently introduced in the literature and based on standard Bayesian computation methods. We find evidence of a strong, positive effect of both overweight peer children in the family and of overweight adults on children weight outcomes. The impact of overweight peer children in the household is larger than the impact of adults. In particular, the estimated confidence sets associated to the peer children variable is positive with upper bound around one or larger, while the confidence sets for the parameter associated to obese adults often include zero and have upper bound that rarely is larger than one.     

The Development of Purpose During Adolescence

While there has been much research on adults' abilities to detect deception, there have been very few studies examining both children's and adults' abilities to detect children's real, spontaneous lies. The present study asked both children and adults to make judgments of children's true and false reports. Participants (N = 156) were shown videotaped sessions of children who were either spontaneously lying or telling the truth. Results indicate that both children's and adults' accuracy for detecting children's true statements was below chance. However, older children were significantly better at detecting lies than both younger children and adults.     

Segmented assimilation and socio-economic integration of Chinese immigrant children in the USA

Research on the new second generation has paid much attention to testing one of the hypotheses posed by segmented assimilation theory – downward assimilation into America's underclass – and has neglected to examine other possible outcomes. In this paper, I address a much understudied pathway – assimilation by way of the ethnic community – based on a case study of Chinese immigrant children in the USA. I show that the children of Chinese immigrants have made inroads into mainstream America through educational achievement, not only because of the strong value their parents put on education but also because resources generated in the ethnic community help actualize that value. The Chinese American experience suggests that, in order to advance to the rank of middle-class Americans, immigrant parents have chosen the ethnic way to facilitate children's social mobility and achieved success. Paradoxically, ‘assimilated’ children have also relied on ethnicity for empowerment to fight negative stereotyping of the racialized other.
