Answer:
1) Body Mass Index (BMI) of a person is calculated byweight divided by the square of height. If a person has high BMI,it means he has high body fatness which is not good forhealth. BMI help us to check the weight categories thatcan cause health problems. For medical insurance BMI depends on theresidential region of the beneficiaries. The lower thesocioeconomic status the higher is the BMI or vice-versa.Residential area provides an estimate of social and economiccircumstances of the beneficiaries. Socio economiccircumstances(SES) and BMI are dependent on the method used tomeasure SES. These variation depends on the sex , income and age.However, only some variables remained associated with importantdifferences by sex. Living in urban areas was associated withhigher BMI than in rural areas. Example, urban areas in Mexico havehigher obesity for both men and women but in developed countries,obesity is higher in rural areas. BMI is valid within the 10 and59 kg/m2 range and height between 1.3 and 2.0 meters.
2) Insurance charges depend on some factors like age, sex,number of children, BMI and whether smoking or not etc. insurancecompanies will increase the premiums i.e they will be charged morespecially for smokers or for those who use tobacco products.Sometimes they charged up to 50 % or more than non-smokers. Arecent study shows that a 45 year old male smoker has to pay 100 to300% more than a nonsmoker for a 20-year, $500,000 life insurancepolicy.
For a health insurance cost, the number of children might chargemore on a plan. Normally when we add a spouse or childonto a plan, the monthly payment or premium increases. This isbecause they’ve charged for each person covered by the plan. But ina family if there are more than three children under the age of 21, there will be charges only for the oldest three children, and nocharges for their two youngest children.
