Level of education, level of income, and level of fatness in adults.

Socioeconomic status is systematically related to the level of fatness, and therefore the incidence of obesity, in a total community survey of nearly 5,000 adults. Among males with more than 12 years of schooling, the average thickness of 4 fatfolds is 10% greater, amounting to about 2 kg of total fat, than those with 8 years or less of education. In females, however, the opposite trend is observed, those in the higher educational group averaging 20% thinner fatfolds, or about 5.5 kg total fat, than females in the lower educational group. These findings confirm the need for standards of obesity that take socioeconomic status into account.

Prenatal origin of brachymesophalangia-5.

As shown in 91 embryos and fetuses in the 41-235 mm crownrump length, brachymesophalangia-5 may be identified in prenatal time. Although the ratios involving different combinations of length of mid-5 relative to other segments yield different frequencies of BMP-5, the short middle segment of the little finger is already associated with clinodactyly and developmental eccentricity as early as the ninth week of prenatal development.

Prenatal origins of carpal fusions.

As shown in 138 embryos and fetuses in the 40-285 mm crown-rump length range, carpal and carpal-metacarpal "fusions" arise from incomplete separation of the cartilaginous precursors rather than from failure of initiation, thus accounting for the "fusions" seen in postnatal radiographs and the grooves that are evident enough in adult fusions. Radiographs selected from over 20,000 apparently normal individuals provide postnatal counterparts for the prenatal examples shown in histological sections.

Paradoxical bilateral asymmetry in bone size and bone mass in the hand.

Among 227 chronic renal disease patients, micrometer caliper radiogrammetric measurements of the second metacarpal at midshaft showed the right metacarpal to be larger (with greater bone area) and with a greater cortical area than the left second metacarpal, both in 208 right-handed individuals and in 19 left-handed individuals. This direction of asymmetry was individually characteristic of the majority of individuals, whether right-handed, left-handed or ambidextrous.

Similarities between parents and their adopted children.

As show in 7,230 parent-child pairs (6,726 biological and 504 adoptive), adoptive parents and their adopted children tend to resemble each other in height, weight and fatfolds to an extent paralleling height, weight and fatfold resemblances of natural (biological) parents and their children. Accordingly, the magnitudes of parent-child resemblances commonly given may not be indicative of the extent of heritability of stature, weight and subcutaneous fat.
