OBJECTIVES: To review the effects of physical activity on health and behavior outcomes and develop evidence-based recommendations for physical activity in youth. STUDY DESIGN: A systematic literature review identified 850 articles; additional papers were identified by the expert panelists. Articles in the identified outcome areas were reviewed, evaluated and summarized by an expert panelist. The strength of the evidence, conclusions, key issues, and gaps in the evidence were abstracted in a standardized format and presented and discussed by panelists and organizational representatives. RESULTS: Most intervention studies used supervised programs of moderate to vigorous physical activity of 30 to 45 minutes duration 3 to 5 days per week. The panel believed that a greater amount of physical activity would be necessary to achieve similar beneficial effects on health and behavioral outcomes in ordinary daily circumstances (typically intermittent and unsupervised activity). CONCLUSION: School-age youth should participate daily in 60 minutes or more of moderate to vigorous physical activity that is developmentally appropriate, enjoyable, and involves a variety of activities. 相似文献

Analysis of general childhood population data showed that there was a significant positive association between total and low-density lipoprotein cholesterol levels and atopy, independent of obesity or sex, which suggest a relationship between hyperlipidemia and greater allergic sensitization among schoolchildren. 相似文献

OBJECTIVE: To examine the effect of plant stanols on lipids and endothelial function in pre-pubertal children with familial hypercholesterolemia (FH). STUDY DESIGN: Children with FH (n=42), aged 7-12 years, were enrolled in a double-blind crossover trial, in which they consumed 500 mL of a low-fat yogurt enriched with 2.0 g of plant stanols and 500 mL of a low-fat placebo yogurt for 4 weeks, separated by a 6-week washout period. Lipid profiles and endothelial function were assessed after both consumption periods. Endothelial function was measured as flow-mediated dilation (FMD) of the brachial artery. RESULTS: This daily intake of 2.0 g of stanols significantly decreased the levels of total cholesterol (TC) by 7.5% and low-density lipoprotein cholesterol (LDL-C) by 9.2% as compared with placebo. High-density lipoprotein cholesterol and triglyceride levels remained unaltered. The reduction of LDL-C levels did not improve FMD, which was 10.5%+/-5.1% after plant stanol consumption and 10.6%+/-5.0% after placebo consumption, respectively (P=.852). CONCLUSION: This study demonstrates that plant stanols reduce LDL-C levels in children with FH without improving endothelial function. 相似文献

OBJECTIVE: To characterize the lipid profiles in patients with types A and B Niemann Pick disease (NPD) and determine if lipid abnormalities are associated with evidence of early cardiovascular disease or correlate with genotype. STUDY DESIGN: The study was a cross-sectional analysis of 10 patients with NPD type A and 30 patients with NPD type B that was carried out in the General Clinical Research Center. For each patient, fasting lipid profile and glucose, T4, height or length, weight, resting blood pressure, and acid sphingomyelinase deficiency genotype were measured. In type B patients, electrocardiograhic-gated helical computed tomography of the heart also was obtained. RESULTS: Lipid abnormalities included low (<35 mg/dL) high-density lipoprotein cholesterol in 100% of patients and hypertriglyceridemia and increased low-density lipoprotein cholesterol in 62% (25/40) and 67% (27/40) of patients, respectively. Coronary artery calcium scores were positive (>1.0) in 10 of 18 type B patients studied. There was no correlation of the Delta R608 genotype with a milder phenotype for the lipid abnormalities, as has been observed for a number of other NPD manifestations. CONCLUSIONS: Lipid abnormalities are part of the phenotype in types A and B NPD and may be associated with early atherosclerotic heart disease. 相似文献

Background and aims
Protein convertase subtilisin/Kexin type-9 (PCSK9) is a substantial player in lipoprotein metabolism. This study was designed to elucidate the role of PCSK9 in the regulation of lipoprotein during the fetal period.Study design and subjects
This study was a cross-sectional study. Eighty-one neonates (45 males, 36 females) who were admitted to the neonatal intensive care unit were enrolled in the study. The median age in gestational weeks and weight at birth were 37.1 weeks and 2493 g, respectively. There were no gender differences, but the proportion of infants who were small-for-gestational age (SGA) was significantly higher among females than males. The prefed serum PCSK9 level was assayed with ELISA kits.Results
The median PCSK9 concentration in male newborns was significantly lower than that in females (148.2 ng/ml vs. 171.4 ng/ml, respectively, p < 0.001). Circulating serum PCSK9 levels were positively correlated with total cholesterol (r = 0.281, p < 0.05) and low-density lipoprotein cholesterol (LDL-C; r = 0.272, p < 0.05). However, there were no correlations between PCSK9 levels and birth weight, gestational age or SGA. Multivariate forward stepwise linear regression analysis revealed that gestational age and circulating PCSK9 levels were independent predictors of the serum LDL-C levels in newborn infants.Conclusion
Our first quantitative analysis of neonatal serum PCSK9 levels at birth showed that circulating PCSK9 levels show gender-based differences and are significantly correlated with LDL-C. These results suggest that PCSK9 could play an important role in regulating LDL-C levels during the fetal period. 相似文献13.

This study aimed to investigate the levels of serum low-density lipoprotein
cholesterol (LDLC) using direct measurement in healthy Japanese school children. The
subjects were 621 children (325 boys and 296 girls) aged 9 to 10 in the 4th grade, and 688
children (334 boys and 354 girls) aged 12 to 13 in the 7th grade. The levels of serum LDLC
and high-density lipoprotein cholesterol were measured by direct determination (Cholestest
LDL and Cholestest NHDL; Daiichi Pure Chemicals Co., Ltd., Tokyo, Japan). In boys in the
4th grade, the mean, the 75th, the 90th and the 95th percentiles of LDLC levels (mg/dl)
were 91.6, 104, 124 and 134, respectively. In girls in the 4th grade, they were 92.8, 108,
122 and 130. In boys in the 7th grade, they were 83.4, 96, 113 and 123. In girls in the
7th grade, they were 93.0, 106, 126 and 137. Serum LDLC levels in boys in the 7th grade
were lower than those of other groups. The direct measurement of serum LDLC level is
useful for evaluation of dyslipidemia in healthy school children, because the method is
applicable to non-fasting serum. 相似文献

Serum high density lipoprotein cholesterol and total cholesterol were studied in 15 children with allergic rhinitis, 45 asymptomatic asthmatic children and 16 children with acute asthmatic attacks. The latter were also studied in their asymptomatic phase. Two control groups of children with minor anatomical defects and those with acute pneumonia with respiratory distress were also studied. The serum concentrations of high density lipoprotein cholesterol were significantly higher (p less than 0.001) and those of total cholesterol lower (p less than 0.001) in children with respiratory allergy when compared to controls. The concentration of high density lipoprotein cholesterol increased and that of total cholesterol decreased during acute asthma. 相似文献
