(Printing information)
[Glossary]
●
BMI (for age 18 or over) / Standard weight
This is an international indicator of obesity which checks the balance
of a person’s weight with respect to their height. It is calculated by the
equation
Weight (kg) ÷ Height (m)
2
. Because people with BMI of 22
have the least cases of diseases medically, it is considered the
standard weight.
●
Obesity index (for age 17 or younger)
This is an indicator of obesity which checks the balance of a person’s
actual weight with respect to the standard weight specified for each
sex, age, and height. It is calculated by the equation
[Actual weight
(kg) - Standard weight (kg)] ÷ Standard weight (kg) x 100
.
●
Body fat
This is a fat accumulated in the body and is classified into
subcutaneous fats and visceral fats. People with large amounts of
subcutaneous fats need to be careful because they are more likely to
develop sleep apnea syndrome, orthopedic disease, menstrual
disorder, and other symptoms.
●
Visceral fat
This is a body fat which has accumulated around the internal organs.
People with large amounts of visceral fats need to be careful because
they are more likely to develop lifestyle-related diseases such as high
blood sugar, high blood pressure, and abnormal lipid metabolism and
also have a higher risk of cerebral infraction and myocardial infarction.
●
Skeletal muscle
This is a muscle which is connected to a bone and moves the body.
You can increase the mass through exercise. People with large
amounts of skeletal muscle consume more energy and do not put on
weight easily.
●
Lean mass
This is determined by subtracting the fat mass from the total body
weight and includes skeletal muscles in addition to heart muscles and
water content. The Limb value is determined by subtracting the fat
mass and the bone mass of limbs from the total weight of limbs.
●
SMI
SMI is an indicator of sarcopenia, in which reduced muscle mass has
decreased muscle power and physical performance. SMI is calculated
by the equation
Lean mass of limbs (kg) ÷ Height (m)
2
.
●
Basal metabolic rate
This is the minimal amount of energy required to live, and it increases
in proportion to the mass of skeletal muscle. The basal metabolism
standard is determined by multiplying the standard value specified for
each sex and age by the body weight. One of the characteristics of
basal metabolic rates is that they are proportional to the body weight.
●
Estimated bone mass
This is the amount of mineral (calcium) contained in bones. This
needs attention because reduced bone mass leads to a higher risk of
osteoporosis.
●
Water content
This is the amount of water contained in the body, calculated from
lean mass. This needs attention because reduced water content leads
to a higher risk of dehydration.
●
Impedance (its printing can be suppressed by a user parameter)
This is an indicator of low and high electrical conductivity in units of
ohms (
Ω
). This is measured by passing currents of two different
frequencies through the limbs and trunk.
