Cardiovascular risk factor prevention in black schoolchildren: two-year results of the "Know Your Body" program
Abstract
A five-year intervention study of the effectiveness of the "Know Your Body" program in reducing coronary heart disease risk factors among black students in the District of Columbia, who were in grades 4-6 at baseline, was begun in 1983. Nine schools were stratified on socioeconomic status and randomly assigned to control and intervention groups. The "Know Your Body" curriculum focuses on nutrition, fitness, and the prevention of cigarette smoking. At baseline, 1,234 students were eligible for the screening in which the following target risk factors were measured: systolic and diastolic blood pressures, ponderosity index, triceps skinfold thickness, postexercise pulse recovery rate, serum total and high density lipoprotein (HDL) cholesterol, and serum thiocyanate. After two years of intervention, results indicated that the program may have had a favorable impact on the following risk factors: systolic and diastolic pressures, HDL cholesterol, ratio of total to HDL cholesterol, fitness (postexercise pulse recovery rate), and smoking. Significant net changes in the favorable direction also were found for health knowledge and attitude toward smoking. Blood pressure reduction was associated with decreased ponderosity and improved fitness, and increased HDL cholesterol was associated with decreased ponderosity. These results are consistent with other evaluations of the "Know Your Body" program, suggesting that the program may be effective in reducing chronic disease risk in diverse school populations.

For Bush 1989, the review judged confounders as controlled (low risk) because a multiple regression analysis adjusted the observed score difference between control and intervention groups for confounders.
“Low risk Quote: Multiple regression analysis was used to adjust the observed difference in scores between the control and intervention groups for these confounders”

For Bush 1989, the review judged data collection methods as unclear risk because there was insufficient data to determine reliability and validity.

For Bush 1989, the review judged selective reporting as low risk because all outcomes identified a priori were reported on.

In Bush 1989, total serum cholesterol differed significantly between groups during intervention years 1 and 2 but not in years 3 and 4.
“During intervention (year 1) 187 189 P < 0.02 During intervention (year 2) 189 189 P = 0.418 During intervention (year 3) 171 167 P = 0.432 Bush 1989 End of intervention (year 4) 431 boys and girls 177 180 P = 0.348”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
