The utility of fat mass index vs. body mass index and percentage of body fat in the screening of metabolic syndrome.

Background: It has been well documented that obesity is closely associated with metabolic syndrome (MetS). Although body mass index (BMI) is the most frequently used method to assess overweightness and obesity, this method has been criticized because BMI does not always reflect true body fatness, which may be better evaluated by assessment of body fat and fat-free mass. The objective of this study was to investigate the best indicator to predict the presence of MetS among fat mass index, BMI and percentage of body fat (BF %) and determine its optimal cut-off value in the screening of MetS in practice.

[Study on the relationship between intake of nutrients and bone density in middle-aged and old people].

Objective: To study the relationship between intake of nutrients and bone density in the middle-aged and the old people.

Methods: Dietary investigation was conducted and bone densities of lumbar 2-4, tuberositas of femur and the neck of femur were measured in 200 healthy subjects who received physical check-up in our hospital. Subjects were distributed into 6 groups including young or middle-aged, pre-old and old groups of men and women.
