Title
Lack of association between television viewing, soft drinks, physical activity and body mass index in children.
Source
Acta Paediatrica. 97(6):795-800, 2008 Jun.
Abstract
OBJECTIVE: To examine the cross-sectional and longitudinal associations of physical activity, screen time and dietary habits on the body mass index (BMI) of children. METHODS: A cohort of 122 girls and 146 boys (age at entry 10 years) from three rural states in the western USA was studied over an 18-month period. Subjects were measured for height and weight. Habitual physical activity, screen time (television viewing, video games and computer use) and dietary variables were assessed by a questionnaire. Cross-sectional and longitudinal analyses were conducted to examine the associations between physical activity, screen time and diet with BMI at baseline and follow-up and change in BMI. RESULTS: At baseline, approximately 10% of boys and girls were obese and 17.8% of boys and 14.8% of girls were overweight. BMI showed a high degree of stability for boys and girls (r = 0.90), whereas physical activity, screen time and dietary habits showed moderate stability (r = 0.31-0.50) !
across the 18-month period. Cross-sectional and longitudinal correlations between physical activity, screen time, diet and BMI were low and non-significant (r < 0.15). The regression models explained between 8% and 22% of the variance in the change in BMI; however, none of the predictor variables were statistically significant. CONCLUSION: Physical activity, screen time and dietary habits were not significantly related to the BMI in cross-sectional or longitudinal analyses. Further research is warranted to better understand the complex, multifactorial phenotype of the BMI in growing and maturing children.

Title
Relations of total physical activity and intensity to fitness and fatness in children: the European Youth Heart Study.
Source
American Journal of Clinical Nutrition. 84(2):299-303, 2006 Aug.
Abstract
BACKGROUND: It is unclear how the amount and intensity of physical activity (PA) are associated with cardiovascular fitness (CVF) and body fatness in children. OBJECTIVE: We aimed to examine the associations of total PA and intensity levels to CVF and fatness in children. DESIGN: A cross-sectional study of 780 children aged 9-10 y from Sweden and Estonia was conducted. PA was measured by accelerometry and was expressed as min/d of total PA, moderate PA, and vigorous PA. CVF was measured with a maximal ergometer bike test and was expressed as W/kg. Body fat was derived from the sum of 5 skinfold-thickness measurements. Multiple regression analysis was used to determine the degree to which variance in CVF and body fat was explained by PA, after control for age, sex, and study location. RESULTS: Lower body fat was significantly associated with higher levels of vigorous PA, but not with moderate or total PA. Those children who engaged in >40 min vigorous PA/d had lower body fa!
t than did those who engaged in 10-18 min vigorous PA/d. Total PA, moderate PA, and vigorous PA were positively associated with CVF. Those children who engaged in >40 min vigorous PA/d had higher CVF than did those who accumulated <18 min vigorous PA/d. CONCLUSIONS: The results suggest that PA of vigorous intensity may have a greater effect on preventing obesity in children than does PA of lower intensity, whereas both total and at least moderate to vigorous PA may improve children's CVF.

Abstract
BACKGROUND: Childhood obesity is a major public health problem in the United States, particularly among American Indian communities. OBJECTIVE: The objective was to evaluate the effectiveness of a school-based, multicomponent intervention for reducing percentage body fat in American Indian schoolchildren. DESIGN: This study was a randomized, controlled, school-based trial involving 1704 children in 41 schools and was conducted over 3 consecutive years, from 3rd to 5th grades, in schools serving American Indian communities in Arizona, New Mexico, and South Dakota. The intervention had 4 components: 1) change in dietary intake, 2) increase in physical activity, 3) a classroom curriculum focused on healthy eating and lifestyle, and 4) a family-involvement program. The main outcome was percentage body fat; other outcomes included dietary intake, physical activity, and knowledge, attitudes, and behaviors. RESULTS: The intervention resulted in no significant reduction in percent!
age body fat. However, a significant reduction in the percentage of energy from fat was observed in the intervention schools. Total energy intake (by 24-h dietary recall) was significantly reduced in the intervention schools but energy intake (by direct observation) was not. Motion sensor data showed similar activity levels in both the intervention and control schools. Several components of knowledge, attitudes, and behaviors were also positively and significantly changed by the intervention. CONCLUSIONS: These results document the feasibility of implementing a multicomponent program for obesity prevention in elementary schools serving American Indian communities. The program produced significant positive changes in fat intake and in food- and health-related knowledge and behaviors. More intense or longer interventions may be needed to significantly reduce adiposity in this population.

Title
Long sleep duration and childhood overweight/obesity and body fat.
Source
American Journal of Human Biology. 21(3):371-6, 2009 May-Jun.
Abstract
To assess the association between short sleep duration and overweight/obesity and body fat (BF) and to identify correlates of short sleep duration in a sample of Portuguese children. A cross-sectional study of children 7-9 years (n = 4511) was performed between October 2002 and June 2003. Weight, height, and skinfolds were measured, and parents filled out a questionnaire about family characteristics as well as sleep duration. The prevalence of overweight/obesity and BF (%) both decreased by long sleep duration. After adjusted for confounders, the odds ratio (OR) for overweight/obesity and sleep duration were as follows: reference >11 h/d; 10-11 h/d, OR: 1.3; confidence interval (CI):1.26, 1.33; 9-10 h/d, OR: 1.16; CI: 1.13, 1.19; and <9 h, OR: 3.22; CI: 3.11, 3.32. Children whose parents had a low educational level slept less time during each night than children whose parents had a higher educational level; children who spent more time watching television slept less time t!
han those who watched less television, and those children engaged in physical activity slept more time each night than sedentary children. Our results showed an inverse relationship between long sleep duration and overweight/obesity prevalence as well as with body fat, and these findings are important because sleep duration is a potentially modifiable risk factor that could be important to consider in the prevention and treatment of childhood obesity.

Title
Serum leptin as a predictor of fatty liver in 7-year-old Korean children.
Source
Annals of Nutrition & Metabolism. 53(2):109-16, 2008.
Abstract
AIM: This study investigated the usefulness of serum leptin as a predictor of fatty liver disease in Korean children. METHODS: One hundred and twenty-four children were recruited from urban areas in Korea. Anthropometrical parameters and clinical variables, such as the levels of serum lipids, insulin and leptin, were measured. Fatty liver disease was detected via hepatic sonogram. We also collected dietary intake data using a 24-hour dietary recall for 3 days. Overweight children were identified using the standards established by the International Obesity Task Force. RESULTS: The prevalence of fatty liver disease was 12.1% among all children and was significantly higher in overweight than in normal children (22.5 vs. 7.1%, respectively; p < 0.05). Within normal weight children, children with fatty livers showed a 2-fold increase in serum leptin levels compared with children with healthy livers (6.2 vs. 2.9 ng/ml, respectively; p < 0.05). Within overweight children, elevate!
d serum leptin levels were observed in children with fatty livers. Multiple logistic regression analysis revealed that serum leptin was strongly associated with fatty liver disease, independent of the body mass index. Energy and fat intake, the frequency of fruit and vegetable consumption, and the frequency of physical activity did not differ among children with or without fatty livers. CONCLUSION: Elevated serum leptin may be a useful parameter when screening for early fatty liver disease among children. 2008 S. Karger AG, Basel

Abstract
The need has never been greater to support healthy eating and physical activity in children and youth; the numbers of overweight and obese children have doubled and tripled, respectively, over the past 3 decades. Poor eating habits, including inadequate intake of vegetables, fruit, and milk, and eating too many high-calorie snacks, play a role in childhood obesity. Grain products provide the highest percentage (31%) of daily calories, followed by "other foods," which have limited nutritional value (22% of daily calories). Snacks account for 27% of total daily calories, which is more than the calories consumed at breakfast (18%) and lunch (24%), but not dinner (31%). For Canadians older than 4 years of age, more than 41% of daily snack calories come from other foods, such as chips, chocolate bars, soft drinks, fruit drinks, sugars, syrup, preserves, fats, and oils. Habits that protect against childhood obesity include eating more vegetables and fruit, eating meals with fami!
ly, and being physically active. Children's food habits and choices are influenced by family, caregivers, friends, schools, marketing, and the media. Successful interventions for preventing childhood obesity combine family- and school-based programs, nutrition education, dietary change, physical activity, family participation, and counseling.

Abstract
OBJECTIVE: To assess the effects of reducing television viewing and computer use on children's body mass index (BMI) as a risk factor for the development of overweight in young children. DESIGN: Randomized controlled clinical trial. SETTING: University children's hospital. PARTICIPANTS: Seventy children aged 4 to 7 years whose BMI was at or above the 75th BMI percentile for age and sex. INTERVENTIONS: Children were randomized to an intervention to reduce their television viewing and computer use by 50% vs a monitoring control group that did not reduce television viewing or computer use. MAIN OUTCOME MEASURES: Age- and sex-standardized BMI (zBMI), television viewing, energy intake, and physical activity were monitored every 6 months during 2 years. RESULTS: Children randomized to the intervention group showed greater reductions in targeted sedentary behavior (P < .001), zBMI (P < .05), and energy intake (P < .05) compared with the monitoring control group. Socioeconomic sta!
tus moderated zBMI change (P = .01), with the experimental intervention working better among families of low socioeconomic status. Changes in targeted sedentary behavior mediated changes in zBMI (P < .05). The change in television viewing was related to the change in energy intake (P < .001) but not to the change in physical activity (P =.37). CONCLUSIONS: Reducing television viewing and computer use may have an important role in preventing obesity and in lowering BMI in young children, and these changes may be related more to changes in energy intake than to changes in physical activity.

Abstract
BACKGROUND: Although several previous projects have attempted to address the issue of child obesity through school-based interventions, the overall effectiveness of school-based programs on health-related outcomes in youth has been poor. Thus, it has been suggested that multi-level interventions that aim to influence healthy lifestyle behaviors at the community, school and family levels may prove more successful in the prevention of childhood obesity. METHODS/DESIGN: This paper describes the rationale, design, and implementation of a community-, school-, and family-based intervention aimed at modifying key behaviors (physical activity, screen time (Internet, television, video games), and nutrition) related to childhood obesity among third through fifth graders in two mid-western cities. The intervention involves a randomized study of 10 schools (5 intervention and 5 control schools). The intervention is being conducted during the duration of the academic year - approximate!
ly 9 months - and includes baseline and post-intervention measurements of physical activity, dietary intake, screen time and body composition. DISCUSSION: We hope this report will be useful to researchers, public health professionals, and school administrators and health professionals (nurses and physical/health educators) seeking to develop similar prevention programs. It is obvious that more collaborative, inter-disciplinary, multi-level work is needed before a proven, effective intervention package to modify behaviors related to childhood obesity can be generally recommended. It is our hope that SWITCH is a step in that direction. TRIAL REGISTRATION: ClinicalTrials.gov NCT00685555.
