Reductions in Cigarette Smoking and Acute Myocardial Infarction Mortality in Jefferson County, Texas
After litigation against the tobacco industry ended in a settlement, the Texas legislature funded pilot projects to reduce tobacco use in selected areas of the state. Subsequent telephone surveys showed that well-funded activities were successful in reducing population rates of self-reported cigarette smoking. We present evidence that the reduction in smoking promptly led to lower rates of death from acute myocardial infarctions

Percentiles of body composition from bioelectrical impedance and body measurements in U.S. adolescents 8–17 years old
Reference percentiles (5th, 10th, 50th, 85th, 90th, and 95th) of black and nonblack children ages 8-17 years from Project HeartBeat! (n = 678) are presented for body mass index (BMI), percent body fat (PBF), fat-free mass (FFM), and fat mass (FM) derived from bioelectrical impedance. Project HeartBeat! is a mixed longitudinal study in which three cohorts of children (seen initially at age 8, 11, or 14 years) were followed for 4 years and measured…

Multilevel Models and Unbiased Tests for Group Based Interventions
For many large-scale behavioral interventions, random assignment to intervention condition occurs at the group level. Data analytic models that ignore potential non-independence of observations provide inefficient parameter estimates and often produce biased test statistics. For studies in which individuals are randomized by groups to treatment condition, multilevel models (MLMs) provide a flexible approach to statistically evaluating program eff…
Body measurement variability, fatness, and fat-free mass in children 8, 11, and 14 years of age
Project HeartBeat! is a four year mixed-longitudinal study of the development of cardiovascular risk factors in White and African American children who at baseline comprised three age cohorts 8, 11, and 14 years. This paper focuses on the anthropometric variables which were chosen to reflect body fat and fat-free mass. Selected anthropometric dimensions are compared with those of samples from the combined National Health and Nutrition Examination…
Is body fat distribution associated with cardiovascular risk factors in childhood
The authors studied the association of cardiovascular risk variables with body fat distribution (BFD) in a cross-sectional sample of 743 Texas schoolchildren of both sexes ages 6-14 years. This association is well known in adults and several useful indices of BFD are available. Whether they are applicable to children remains a question of importance for epidemiological investigations in this age group. Canonical correlations between anthropometri…
Body circumferences as measures of body fat distribution in 10–14‐year‐old schoolchildren
In this paper the hypothesis is tested that circumferences are as useful as skinfolds in children aged 10–14 years to detect variation in regional fat distribution. This would be confirmed by the appearance of a significant canonical correlation between a vector of appropriately selected circumferences and an analogous vector of skinfolds, producing a weighted pattern suggestive of centralized obesity (that is a series of mathematical weights of …
Body circumferences as alternatives to skinfold measures of body fat distribution in children
The ratios of circumferences (waist/hip, waist/thigh) have been proposed in lieu of skinfold measurements for studies of obesity and body fat distribution in adults. The skinfold method has been used successfully in children to study the growth and development of patterns of body fat distribution, but circumferences have not. We studied the relationship between these two methodologies as indicators of body fat and its anatomical distribution amon…
