| | NEJM -- Familial dependence of the resting metabolic rate |
 | | We studied 130 nondiabetic adult southwestern American Indians (74 men and 56 women) from 54 families to determine whether the resting metabolic rate, as measured by indirect calorimetry, is a familial trait that is independent of individual differences in fat-free mass (estimated mass of metabolically active tissue), age, and sex. |
 | | We found that most of the variance in the resting metabolic rate (83 percent, P less than 0.0001) was accounted for by three covariates--fat-free mass, age, and sex--and that fat-free mass was the most important determinant. |
 | | Thus, resting metabolic rate is a familial trait in this population, and it is independent of differences in fat-free mass, age, and sex. |
