Objective

The aims of this study of predominately racial/ethnic minority children in foster care (N = 360, birth to 19 years old) in Los Angeles, CA were to examine the (1) prevalence of obesity (≥95 percentile) and overweight/obese (≥85 percentile) upon entrance to foster care (T1) and after 1 year in foster care (T2); (2) comparison of high weight categories to national statistics; (3) relationship of changes in weight status to age, reason for entry into foster care, and placement.

Methods

Chi-square test and McNemar test comparing paired proportions were used to determine whether there were significant changes in the proportion of high weight categories between T1 and T2. Chi-square test or Fisher's exact test were used to evaluate the association between age, placement, and reason for foster care with the change in weight category. Changes in weight were categorized as (1) decreased in weight, (2) remained at overweight or obese, (3) increased in weight, or (4) remained normal.

Results

The proportion of obese and obese/overweight children between ages 2 and 5 were significantly lower at T2 than T1. There were no significant changes in the prevalence of obesity for the total population at T2. Children age 6 or older had a higher prevalence of obesity and overweight/obesity compared to national statistics. Of children at all ages, 64.7% of children of all ages entered foster care with a normal weight and stayed in the normal range during their first year in foster care, 12.2% decreased their weight, 15.4% remained overweight or obese, and 7.7% increased their weight. Age and parental substance use was related to change in weight category from T1 to T2.

Conclusion

Children did not become more overweight or obese in foster care; however 28% of the children were obese or overweight upon entry into foster care. Children who are 6 years or older and obese upon entering foster care should be targeted for weight reduction. The pediatric community and child welfare system need to work together by including weight percentiles in the foster care file and training/monitoring child welfare caregivers in weight reduction interventions.  相似文献

The objective of this study was to determine whether children's characteristics and/or institutional characteristics were predictors of severe punishments (including beatings) and/or frequency of punishments that children received from staff in Romanian institutions. The data was hierarchical with institutionalized children (N = 1391) nested within 44 institutions, and the measurement of punishments by the staff and frequency of punishments had a binary distribution. Thus, multilevel logistic regression models were used to examine the effects of individual and institutional level variables on reported punishments and to account for the clustering of the children within institutions. Two general patterns of results emerged. First, regarding individual level variables, it was found that: (1) amount of time spent by children in their current institutions had a significant effect on the probability of being punished by staff and the frequency of this punishment; (2) the probability of being punished was higher for boys than for girls; and (3) having no siblings in the institution increased the odds of being punished several times. Second, regarding institutional level variables: (4) being in placement centers for school-aged children with a traditional type of institutional organization increased the odds of severe punishment compared to a familial/mixed type. The results of the present study highlight the importance of understanding the consequences of institutionalization in a broader way, where children not only experienced early severe psychosocial deprivation as documented in other studies, but also high levels of severe punishments administered by institutional staff.  相似文献

The dominant culture in labor and birth is the medical model, not the midwifery model of woman-centered care. Consensus among professional and governmental groups is that, based on the evidence, intermittent auscultation is safer to use in healthy women with uncomplicated pregnancies than electronic fetal monitoring (EFM). Barriers impact the laboring woman’s ability to give informed choice regarding fetal monitoring. Lack of informed choice denies a woman her right to be in control of her birth experience, and is in opposition to a woman’s right to autonomy and self-determination.  相似文献

Abstract

This study explored early childhood teachers’ views relating to culture and play by collecting information from them on cultural differences and parental perceptions of play, culturally appropriate play (CAP) practices and barriers in its implementation. The participants of the study were 14 early childhood educators working in long day care (LDC) or out, of, school, hours care (OOSH) settings located in Sydney, Australia. Children in the selected centers represented various cultural and linguistic backgrounds.

Teachers in the present study reported noticeable differences in the play of children of diverse cultural backgrounds. However, they believed that the differences in children's play were attributable to the children's proficiency in English language and gender rather than to their culture. The teachers reported they had limited or no information on the children's cultural patterns of play at home. The lack of information on cultural patterns of play, perhaps, has led to difficulties in understanding the cultural origins of play or in accommodating cultural differences into programming. The results highlight the need for educators to have greater knowledge of the cultural bases of play to enable them to provide, in partnership with parents, culturally appropriate play experiences for children.  相似文献

The main purpose of this study was to investigate the differences between pre-service and in-service teachers in terms of their levels of teaching efficacy and teaching professionalism. In addition, the patterns in predictors of teachers’ teaching efficacy were compared between the two subgroups of this study. Five hundred and seventy-three teachers completed self-administered questionnaires. The in-service teachers were found to have higher efficacy than their counterparts in only one of the six subscales of teaching efficacy, the subscale “Teaching Strategies”. Additionally, the college major specialisation and some domains of professionalism were found to be predictive to both groups. Along with the main results of this study, implications for research and practice are discussed.  相似文献

Diversity, child care quality, and developmental outcomes   总被引:3,自引:0,他引:3  
It is widely accepted that high quality child care enhances children’s cognitive and social development, but some question whether what constitutes quality care depends on the child’s ethnic and cultural background. To address this question, secondary analysis of data from the two largest studies of child care experiences in the United States, Cost, Quality, and Outcomes Study and the NICHD Study of Early Child Care, tested whether standard measures of child care quality were less reliable or valid for African-American and English-speaking Latino children than for white children. Widely used measures of child care quality showed comparably high levels of reliability and similar levels of validity for white, African-American, and Latino children. Analyses tested whether cognitive and social skills were related to child care quality, the match between child’s and caregiver’s ethnicity, and the match between the mother’s and caregiver’s beliefs about child-rearing. Results indicated children from all three ethnic groups showed higher levels of cognitive and social skills on standardized assessments shown to predict school success when caregivers were sensitive and stimulating. Children’s skills were not consistently related to whether the child’s and caregiver’s ethnicity matched or whether the mother’s and caregiver’s beliefs about child-rearing were similar. These two large studies suggest that children from all three ethnic groups benefit from sensitive and stimulating care on child outcomes related to school success. The results are interpreted as indicating that the global dimension of quality may be reflected in very different types of practices that reflect cultural differences.  相似文献
