Race-ethnicity-specific waist circumference cutoffs for identifying cardiovascular disease risk factors

BACKGROUND: Waist circumferences (WCs) in white men and women that represent a risk of cardiovascular disease (CVD) equivalent to that of body mass indexes (BMIs; in kg/m2) of 25 and 30 have been identified. However, WC cutoffs for other race-ethnicity groups remain unknown. OBJECTIVE: The objective was to determine WC cutoffs for CVD risk in […]

Relation of body mass index to asthma and atopy in children: the National Health and Nutrition Examination Study III.[see comment]

BACKGROUND: An increase in the prevalence of obesity and asthma over recent decades has been reported in affluent societies. Both overweight and obesity have been shown to be inversely related to having been breastfed, which is also a potential protective factor against childhood atopic diseases. The aim of this analysis was to explore the relation […]

Couch potatoes or french fries: are sedentary behaviors associated with body mass index, physical activity, and dietary behaviors among adolescents?

OBJECTIVE: To describe the demographic characteristics of adolescent boys and girls who engage in three sedentary behaviors (television/video use, computer use, and reading/homework), and to explore how each sedentary activity is associated with body mass index (BMI), dietary behaviors, and leisure time physical activity. DESIGN: This study draws on data collected from Project EAT (Eating […]

Self-reported prevalence and health correlates of functional limitation among Massachusetts elderly Puerto Ricans, Dominicans, and non-Hispanic white neighborhood comparison group

BACKGROUND: Limited data suggest that Puerto Ricans experience greater disability than other ethnic groups, but few studies have examined the factors associated with this apparent difference.

Body mass index is different in normal Chinese and Caucasian infants

Body mass index (BMI) is one of the anthropometric measurements for assessing nutritional status, body composition and adiposity in children. Racial differences in BMI between black and white children and adolescents have been shown in several studies. The aim of this study was to determine whether an ethnic difference in BMI exists between Chinese and […]
