New equations to estimate basal metabolic rate in children aged 10-15 years

Article Abstract:

New regression equations for estimating the basal metabolic rate (BMR) in 10- to 15-year-old children were derived by including pubertal stages into the equations. The mixed-longitudinal study, sponsored by Lausanne, Switzerland-based Nestle Foundation, used a sample of 165 school children in Oxford, England. In either gender, weight was found to be the most important factor in the equations. Overall, the inclusion of pubertal stage only resulted in marginal improvements to the estimated BMR.

Basal metabolic rate of women on the contraceptive pill

Article Abstract:

The basal metabolic rate (BMR) varies randomly by only 2.4-4.87% in individual women taking contraceptive pills and can be regarded as a biological constant. A study conducted on five women taking the pill indicates that the biphasic pattern of cyclicity and variation in the BMR seen in fertile women is absent in women on the pill. The peak in the BMR during the late luteal phase is absent, probably due to the suppressive effect of the pill on an increase in the levels of progesterone.

The validity of predicting the basal metabolic rate of young Australian men and women

Article Abstract:

The Hayter and Henry equations (1994) are more accurate in measuring the basal metabolic rate (BMR) of young Australian men and women than the Schofield et al (1985) equations. BMR was estimated using indirect calorimetry while bioelectric impendence analysis was employed to measure fat free mass and fat mass. Women on oral contraceptive agents had a significantly higher BMR when adjusted for body weight or body composition as compared to those not on oral contraceptive agents.
