What is Body mass index (BMI)
What is BMI ??
Body mass index (BMI) is a measure of body fat based on your weight in relation to your height, and applies to most adult men and women aged 20 and over. For children aged 2 and over, BMI percentile is the best assessment of body fat.
- Body mass index (BMI) is a measure of relative size based on the mass and height of an individual.
- The Quetelet Index was devised by Adolphe Quetelet, a Belgian mathematician, astronomer and statistician, in 1832. It was later termed "body mass index" in 1972 by Ancel Keys.
- BMI is a simple, inexpensive and noninvasive surrogate measure of body fat.
- Factors such as age, sex, ethnicity and muscle mass are not accounted for in BMI.
- For adults 20 years and older, BMI is interpreted by using standard weight status categories that are the same for all ages, and for both men and women.
- For children and adolescents between 2-20 years old, BMI is interpreted relative to a child's age and sex.
- BMI is a reasonable indicator of body fat for both adults and children.
- Because BMI does not measure body fat directly, it should not be used as a diagnostic tool.
- BMI should be used as a measure to track weight status in populations and as a screening tool to identify potential weight problems in individuals.
- Other measures of body fat, such as skin-fold thicknesses, bio-electrical impedance, underwater weighing and dual energy X-ray absorption, maybe more accurate than BMI.

O Positive Blood
O pOsitive blOOd facts
O Positive Blood Type (O+)
1.
Most Common Blood Type
The O positive blood type is the most common and
incredibly an important donor in maintaining adequate blood supply. It is
present in 1 out of 3 individuals. This means approximately 37.4% of the
population has O positive blood. However, not all of the ethnic groups
share the same proportions of blood types. O positive blood type is about 37%
in Caucasians, 47% in African American, 53% in Hispanic, and 39% in Asian.
2. Inheritance Patterns
The ABO
gene found on chromosome 9 determines the ABO blood group system. O genes (or
alleles) do not produce antigens A or B, thereby are called silent
alleles. Blood Group O has neither A or B antigen on red cells
but with both the A and B antibody in the plasma.
How is O Positive blood type inherited?
·
If
parental blood groups consist of O and O, the child’s blood group will be O.
·
If
parental blood groups consist of O and A, the child’s blood group will either
be O or A.
·
If
parental blood groups consist of O and B, the child’s blood group will either
be O or B.
·
If
parental blood groups consist of A and A, the child’s blood group will either
be O or A.
·
If
parental blood groups consist of A and B, the child’s blood group will either
be one of O, A, B, or AB.
·
If parental blood groups
consist of B and B, the child’s blood group will either be O or B.
3. Blood Type Compatibility: O+ Can Receive
Both O+ and O-
Being
the most common blood type, it is transfused most often. O Positive individuals
can only receive both O+ and O- because they have antibodies to both A and B
antigens in their blood. If A and B is introduced, it will cause an immune
response.
4. Blood Type Compatibility: O+ Can Be Given
To O+, A+, B+ and AB+
Being an
O+ donor makes the person the type of individual to hold being the most ideal
red blood benefactor. Individuals with an O+ blood type can be a red blood cell
donor to blood types O+, A+, B+, and AB+.
5. Plasma Type Compatibility: O Can Receive
O, A, B and AB
Blood
Type O carries both antibodies, making blood type O group compatible to receive
plasma from groups O, A, B and AB. However, blood type O plasma can only be
given to type O recipients. The individuals who are compatible
in receiving platelets from an O+ donor are O+ recipients.
6. Has an Rh Factor
Rh
Factor is an additional marker in the blood. This can be classified as either
Rh positive or Rh negative. This marker is only used for genetic differences. O
Positive blood type is Rh positive.
7. Tendency Towards Higher Levels of Stomach
Acids
Individuals
with blood type O may be predisposed to certain medical conditions like ulcers.
This can happen because of higher levels of stomach acids. However, they have
well-built ability to digest protein and fat-rich meals. The two chemicals
intestinal alkaline phosphatase enzyme and ApoB48 lipoprotein used by the
digestive tract are secreted at much higher levels. It improves the ability of
blood type O individuals to metabolize animal sourced cholesterol more
efficiently. However, simple carbohydrates such as those sourced from grains,
are easily converted into triglycerides and fats.
8. Immediate “Fight or Flight” Response
This can
cause episodes of excessive anger, hyperactivity, temper tantrums, and chemical
imbalance bringing about manic experiences. Blood Type O individuals are also
vulnerable to destructive behaviors when exceedingly bored, tired or depressed,
due to the synergistic relationship between feelings of reward and release of
dopamine.
9. Diet Recommendations
It is
recommended for blood type O individuals to focus their diet on organic meats,
fruits and vegetables to avoid being overstressed. Moreover, dairy and wheat
products should be avoided because they may initiate digestive and health
concerns. Intake of caffeine and alcohol should also be avoided. They can be
harmful with their potential to increase adrenaline and noradrenaline which are
already in high levels in blood type O individuals.
10. Exercise Recommendations
Brisk
regular exercise that promotes the musculoskeletal and cardiovascular system
can be beneficial. Physical exercise releases a crowd of neurotransmitter
activity to tone the whole system. It also helps uphold a physical health and
emotional balance due to a well regulated and efficient chemical transport
system. Aaerobic physical exercise should be done 3 to 4 times a week for at
least 30 minutes each.
