fat hand

Parents these days are worried about the increasing fatness of their child, but are unable to find the reason. A new study suggested that it’s not the kids fault for their fatness as their Body Mass Index (BMI) is 35-40% inherited from the parents.

The study, conducted by an international team of researchers, revealed that obesity among children is hereditary and parents’ fatness influence deeply on the increasing waistline of their offspring. As suggested by the new research, led by a team of analysts from the University of Sussex, kids are 35-40% more prone to take over body mass index (BMI) from their parents. For most of the overweight children, the percentage rises to 55-60, indicating that inheritance and family physics determine more than half of the children’s propensity towards fatness.

The researchers, for calculating the result, used data regarding the heights and weights of nearly 100,000 children and their parents ranging from six leading nations worldwide including the UK, USA, China, Indonesia, Spain and Mexico. After going through a thorough inspection of the data, the researchers found that 0.2 per parents of the total partakers have the same intergenerational diffusion of Body Mass Index (BMI). In this context, they calculated that the average BMI of each child comes from his/her parents – 20% from the mother and 20% from the father.

According to the lead author Professor Peter Dolton of the University of Sussex, Our research is giving a crucial and exceptional insight into how obesity is passed on across generations in both developed and under-developed countries. Irrespective of the different types of economic development level of the country, the distinct scale of industrialisation, and versatility of economy, the patterns of BMI and process of intergenerational transmission are found to be approximately invariable in all six countries.”

The study, with the detailed report, appears in the journal Economics and Human Biology.
