Maternal Overnutrition: A Major Cause of Increased Obesity Prevalence?

Published:June 5th, 2011

One of the major health care concerns in the twenty-first century is obesity. In fact, its prevalence is continuously increasing in exponential rate over the past few decades in developed and even in underdeveloped countries. According to a study published in the May 2011 issue of the International Journal of Obesity,  this may be a result of maternal overnutrition during pregnancy and lactation.

Such a rapid rise in obesity rate cannot be explained by a change in the genotypic characteristics of human beings alone. Therefore, it may be a result of an interplay between environmental factors and their effects to the human genes.

It is now known that environmental factors such as unhealthy diet and decreased level of physical activity can greatly influence the risk for weight gain and increased body mass index.

However, current findings have pointed out the possible relationship between overly increased nutrition during early life stages and the predisposition to overweight and obesity. Thus, nutrition during the early life is but critical for starting medical intervention to reduce the prevalence and maybe eliminate the growing stats of obesity.
