[Application of bioelectric impedance measurement in the evaluation of body fat].
We compared the data referring to the percentage of body fat in 40 healthy adults (20 males and 20 females) of different weight, aged between 18 and 33 years, measured by biological impedance analysis and skinfold thickness measurement. Of these, 26 were shown to be of normal weight, 9 overweight and 5 underweight according to the body mass index (Weight/Height). All subjects were analysed for bioelectrical impedance with a BIA-103 (Ryl-Detroit) appliance and the skinfolds were measured with a Harpenden Caliper. The correlation between the values obtained with the two methods was shown to be linear and highly significant for both sexes (males: r = 0.71; females: r = 0.77). The study also showed that the content of body fat was higher than the mean values indicated in the literature for the age range considered in 23% of the males and 31% of the females of normal weight.
