It has been suggested that changes in fat-free weight may not fully explain the decline of resting metabolic rate (RMR) that occurs with aging. We therefore examined the hypothesis that a reduction in maximal aerobic capacity (VO2max) may partially explain the lower RMR in older men, after accounting for differences in fat-free weight and fat weight. We also considered differences in energy int...

SETTING The dual epidemics of HIV-TB including MDR-TB are major contributors to high morbidity and mortality rates in South Africa. Rifampicin (RIF) resistance is regarded as a proxy for MDR-TB. Currently available molecular assays have the advantage of rapidly detecting resistant strains of MTB, but the GeneXpert does not detect isoniazid (INH) resistance and the GenoTypeMTBDRplus(LPA) assay m...

Background: Resting metabolic rate (RMR) quantifies the minimal energy required to sustain vital body functions and is a crucial component of childhood development. Mean RMR per unit mass (RMR/BM) has very accurately been modelled in references for Caucasian adolescents.Objectives: Here we address extent which such model can be adapted explain RMR/BM Indian children.Subjects Methods: The multic...

The purpose of this study was to analyze the accuracy of predictive equations for resting metabolic rate (RMR) and daily energy expenditure in policemen on a rotating shift. Subjects were 28 healthy policemen on a rotating shift (males) age of 23-46 years. The participants' RMR was measured by using indirect calorimetry (TrueOne2400) and also calculated from various predicted equations of RMR (...

BACKGROUND Underweight as a public health problem in young women is associated with nutritional deficiencies, menstrual irregularity, eating disorders, reduced fertility, etc. Since resting metabolic rate (RMR) is a necessary component in the development of nutrition support therapy, therefore we determined the accuracy of commonly used predictive equations against RMR measured by indirect calo...

We considered the association of several metabolic and lifestyle variables as modulators of the decline in resting metabolic rate (RMR) and fat-free weight (FFW) in 183 healthy females (18-81 yr). RMR showed a curvilinear decline with age, which was significant in women aged 51-81 yr but not in women aged 18-50 yr. FFW showed a curvilinear decline with age, which was significant (P < 0.01) in w...

In response to variation in food availability and ambient temperature (Ta), many animals show seasonal adaptations in their physiology. Laboratory studies showed that thyroid hormones are involved in the regulation of metabolism, and their regulatory function is especially important when the energy balance of an individual is compromised. However, little is known about the relationship between ...

Predictive equations provide the basis for estimating energy needs for different individuals; however, accuracy of these equations has been questioned in tropical countries. The current study determined which of the commonly used predictive equations is most suitable for estimating resting metabolic rate (RMR) in a random sample of obese diabetic and obese non-diabetic subjects in Sudan. Two ma...

BACKGROUND Little is known about the regulation of adiponectin. Animal studies suggest local regulation by adipocytokines or alterations in energy expenditure, and studies in humans suggest regulation by alcohol intake and ethnicity. OBJECTIVE To identify regulators of adiponectin in humans, we measured resting metabolic rate (RMR), serum adiponectin, glucose, insulin, triacylglycerol, alcoho...
