Indices of relative weight and obesity.

Analyses are reported on the correlation with height and with subcutaneous fat thickness of relative weight expressed as per cent of average weight at given height, and of the ratios weight/height, weight/height squared, and the ponderal index (cube root of weight divided by height) in 7424 ‘healthy’ men in 12 cohorts in five countries. Analyses are also reported on the relationship of those indicators of relative weight to body density in 180 young men and in 248 men aged 49–59. Judged by the criteria of correlation with height (lowest is best) and to measures of body fatness (highest is best), the ponderal index is the poorest of the relative weight indices studied.

Serum cholesterol response to changes in the diet: IV. Particular saturated fatty acids in the diet.

For many dietary changes satisfactory prediction of the average change in the serum cholesterol level of man in mg./100 ml., is given by Δ Chol.

Serum cholesterol response to changes in the diet: III. Differences among individuals.

Data from 227 men in 10 sets of controlled dietary experiments in 5 institutions gave the least-squares solution: [see text] with S.E. of slope --±0.

Serum cholesterol response to changes in the diet: II. The effect of cholesterol in the diet.

The series of metabolic ward experiments, with 22 physically healthy men in each, covered dietary cholesterol intakes from 50 to 1450 mg. daily, with all other variables controlled. The serum-cholesterol data, plus the data from comparable experiments reported from 4 other institutions, were analyzed in regard to average serum cholesterol response (Δ Chol.
