Since the American Heart Association last presented nutrition guidelines for children, significant changes have occurred in the prevalence of cardiovascular risk factors and nutrition behaviors in children. Overweight has increased, whereas saturated fat and cholesterol intake have decreased, at least as percentage of total caloric intake. Better(More)
CONTEXT Prevalence of adolescent overweight in the United States has increased substantially during the past 3 decades. Whether socioeconomic disparities in adolescent overweight increased, decreased, or remained constant during this period is not known. OBJECTIVE To examine trends in adolescent overweight from 1971 to 2004 by family poverty status, as(More)
Fast-food marketing to children is considered a contributor to childhood obesity. Effects of marketing on parents may also contribute to childhood obesity. The authors explore relevant hypotheses with data from caregivers of 2-to 12-year-old children in medically underserved communities. The results have implications for obesity-related public policies and(More)
BACKGROUND There are few data on overweight in children in developing countries. Such data are important to guide public health policy. We assessed trends in the prevalence of overweight and obesity in children from the Seychelles, a middle-income island state in the Indian Ocean. METHODS Multiple cross-sectional surveys were conducted each year between(More)
OBJECTIVE With the increasing prevalence of pediatric obesity, it is important to identify high-risk populations of children to direct limited resources for prevention and treatment to those who are most vulnerable. The objectives of this study were to determine the prevalence of overweight in children who are clients of community health centers in(More)
The question that underlies the study by Corvalán et al., 1 published in this issue of 'International Journal of Epidemiology', has far-reaching consequences: what is the growth pattern that will lead to optimal health both in the short-and long-term for children living in countries in nutritional transition? A few decades ago, when obesity, hypertension,(More)
OBJECTIVES Our objective was to compare serum lipid profiles, total cholesterol (TC), low-density lipoprotein (LDL), triglycerides (TG), and high-density lipoprotein (HDL) between children with Down syndrome (DS) and their non-DS siblings. We hypothesized that the children with DS would have higher TC, LDL, and TG and lower HDL. The secondary aim was to(More)
This study compared child-feeding and related practices with child weight status between Chinese-American and non-Hispanic white caregivers who attended three community health centers. Study participants were caregivers of 50 Chinese-American and 108 non-Hispanic white children aged 2-12 years who completed a short version of the child feeding questionnaire(More)
BACKGROUND Obesity associated with joint pain of the lower extremities is likely due to excessive mechanical load on weight bearing joints. Additional mechanical factors may explain the association between obesity and joint pain. FINDINGS We characterized the association between obesity and non-traumatic lower extremity (LE) joint pain in adolescents and(More)
BACKGROUND Children with Down syndrome (DS) have a higher prevalence of obesity than other children. Whether this increased risk for obesity is due to a lower resting energy expenditure (REE) is controversial. Our study assessed whether (1) the REE of children with DS adjusted for fat-free mass (FFM) was lower than that of sibling controls, and (2) the(More)
