PURPOSE: The purpose of this study was to identify the effects of a physical activity-behavior modification combined intervention(PABM-intervention) on metabolic risk factors in overweight and obese elementary school children. METHODS: Thirty-two participants (BMI≥85 percentile or relative obesity≥10) were allocated to the PABM-intervention group and behavior modification only intervention group. The PABM-intervention was composed of exercise intervention consisting of 50 minutes of physical activity(Hip-hop dance & gymbased exercises) twice a week and the behavior modification intervention consisted of 50 minutes of instruction for modifying lifestyle habits (diet & exercise) once a week. Effectiveness of intervention was based on waist circumference, BP, HDL-cholesterol, TG, and fasting glucose before and after the intervention. RESULTS: The proportion of subjects with 1, 2, 3 or more metabolic risk factors were 28.1, 43.8, and 15.6%, respectively. After the 8-week intervention, waist circumference, systolic BP, diastolic BP, and HDL-cholesterol changed significantly(p<.01) in the PABM group. CONCLUSION: This provides evidence that a PABM-intervention is effective in changing metabolic risk factors such as waist circumference, systolic BP, diastolic BP, and HDL-cholesterol in overweight and obese elementary school children.
The purpose of this study was to explore the relationships of family strain, perceived social support, family hardiness, and family adaptation and identify the family resiliency factors for the adaptation of families who have a child with congenital heart disease.
The sample consisted of 90 families who had a child diagnosed with congenital heart disease and completed surgical treatment. Data was collected from parents using a questionnaire.
Results from path analyses revealed that family strain had a direct effect on both perceived social support and family hardiness, and an indirect effect on family adaptation. Also, the findings revealed that perceived social support had a direct effect on both family hardiness and family adaptation, and family hardiness had a direct effect on family adaptation. Thus, these results indicated that perceived social support and family hardiness had a mediating effect on family strain.
Findings provide the evidence for the theoretical and empirical significance of perceived social support and family hardiness as family resiliency factors for family adaptation. Clinical implications of these findings might be discussed in terms of family-centered nursing interventions for the families who have a child with congenital heart disease based on an understanding of family resiliency for adaptation.
This study was to explore the prevalence of alcohol experiences and to identify the expectancy on the effects of alcohol and alcohol knowledge in early adolescents.
The cross-sectional survey of 1854 students from seven middle schools in one district of Seoul was conducted by convenience sampling. Alcohol experience and early onset of alcohol use were measured by the Youth Risk Behavior Survey. Alcohol expectancy was measured by an Alcohol Effects Questionnaire.
Over sixty five percent of adolescents reported that they had previous drinking experiences. The participants with no alcohol drinking experience had a lower level of alcohol knowledge than those with experience(t=2.73, p=.007). In expectancy on effects of alcohol, girls had a more positive alcohol expectation than boys(t=-2.54, p=.011). Alcohol knowledge negatively correlated with alcohol expectancy(r=-.40 p=.000). In regression of alcohol expectancy, gender and alcohol knowledge were significant predictors explaining 17%.
The results support that alcohol expectancy is an important link with early drinking experiences and alcohol knowledge, focusing on the importance of gender differences. Therefore, an alcohol prevention program in early adolescence is needed and should be focused on multidimensionality of the alcohol expectancy with developmental and psychosocial factors for early adolescents.
