Introduction

Wright, M. BMC Med Genet ; 9 : 4. Although the definition of obesity and overweight has changed over time [ 1415 ], it can be defined as an excess of body fat. The research does serve as a wake-up call to couples planning a child and obstetricians. The U-shaped relation indicates that a higher prevalence of obesity will eventually be seen among those born with a very low birth weight as well as among those with a birth weight at the opposite end of the distribution.

Genetics is not the only cause of obesity. The term eating disorders refers to a group of medical problems that have an unhealthy focus on eating, dieting, losing or gaining weight, and body image. The evidence for a genetic contribution to adult body weight and obesity as derived from genetic epidemiology models has been reviewed in detail elsewhere A doctor is the best source to tell you whether illnesses, medications, or psychological factors are contributing to weight gain or making weight loss hard. Fawcett and I.

Many people have a very hard time breaking obesity genetics habits. Vogel, S. However, in the end, the results for the new candidate genftics were affected by the same limitations as the candidate genes identified from our current understanding of the biology of the regulation of energy balance. Indeed, like many of the other replication efforts, FTO shows the strongest association with BMI in our large European American pediatric cohort [ 98 ]. BJOG ; : — 9. Hinney, T. Duerr, K.

Nevertheless, the variation in how people respond to the same environment suggests that genes do play a role in the development of obesity.

Medical Factors. Psychosocial aspects of obesity. Studies childhood obesity genetics from different parts of India within last decade are also indicative of similar trend. Other community factors include the affordability of healthy food options, peer and social supports, marketing and promotion, and policies that determine how a community is designed. A systematic review of information about more thanadults found that carriers of the common FTO gene variant most consistently associated with obesity were able to reduce their risk through physical activity.
