Factors responsible for causing obesity &

Epidemology

OBESITY - Obesity can be defined as a medical condition in which excessive fat is accumulated in the body to a greater extent that may cause damage to the health & may even reduce the life span.[1]

According to NIH(National Institutes of Health) report,Obesity is defined as 'the condition of having an abnormally high proportion of fat... a complex multifactorial chronic didease that develops from an interaction of genotype and the environment'[2]

BMI(BODY MASS INDEX) - It is an index to define overweight.

Calculation[2]-

The ranges of BMI are as follows[2][3]:

CAUSES FOR OBESITY/ FACTORS CONTRIBUTING TO OBESITY -

Excessive intake of food - When extra energy is consumed it will be stored in the form of body fat. Theoretically, reducing the calorie intake by 500Kcal/day may result in a weight loss of 1 pound/week.[2]

Lack of Physical Activity/Sedentary life style - There is a risk of gaining 5Kg or more weight in people with less physical activiy.[4]

Genetic Susceptability [5] - A study showed that, infants born to obese mothers were less active & gained more weight within the age of 3 months when compared to infants of normal weight mothers.

Alcohol Consumption - Alcohol is very rich in calories & it can also show its affect on the bosy metabolism. Frequent light/moderate drinkers may not cause obesity but infrequent heavy drinkers may lead to overweight.[6][7]

EPIDEMOLOGY - As per 2005, the estimation of WHO says that 400 million adults are obese & the prevalence is more in women comparitively. Severe obesity is seen in U.S.,Australia and canada.obesity is common in all countries except in sub-saharan region.[8]

Hai Ganesh, Thanks for ur comment. There are 4 typres of tissues in our body. They are- 1. Connective tissue 2. Muscle tissue 3. Nervous tissue & 4. Epithelial tissue[1] Adipose tissue is a typr of loose connective tissue & its function is to store fat.[2] REFERENCES: 1. http://en.wikipedia.org/wiki/Body_tissue 2. http://en.wikipedia.org/wiki/Adipose_tissue
