Sarcopenic obesity occurs when there is a loss of muscle and gain of fat in the body. With this study, the investigators will explore how nutritional status at the beginning of the treatment can cause changes in your child's body fat compared to muscle in the body. The investigators will also look at how these changes can impact a child's cancer treatment, survival from treatment, and if there is any deterioration in health and nutrition status. The primary objective of this study is to establish the incidence of sarcopenic obesity, measured by dual-energy x-ray absorptiometry (DEXA), among Indian children and adolescents with acute lymphoblastic leukemia (ALL).

Survival of childhood ALL exceeds 80% in an increasing number of many low-middle income countries (LMIC). Recent studies have found that the effects of obesity on survival are observed within the first several years of diagnosis, thus impacting immediate health outcome. Of concern is the developing body of evidence that the effects of obesity may be underestimated and its effect on outcome may be even more pronounced when it is defined by body composition. An elevated body mass index (BMI) can be comprised of increased fat-free mass (FFM) or fat-mass (FM) or a combination of both. Evidence suggests that an increase of FM is a stronger predictor of risk of chronic disease rather than BMI. The evaluation of FM and FFM appears to have clinical implications in both adult and pediatric oncology, particularly in patients with Sarcopenic Obesity (SO) (increased FM and reduced FFM). Among children with ALL located in both high income countries (HIC) and LMIC, remediation of poor nutritional status during treatment removes its adverse effect on survival at the end of treatment. targeting dietary patterns may be a more effective approach when considering dietary interventions. One plausible way to examine the association of dietary patterns with the development of SO in pediatric ALL is to compare a vegetarian diet to a non-vegetarian diet and investigate how they are associated with its development. Children and adolescents with ALL at Tata Memorial Center (TMC) are well suited for this investigation because at least 30% of children follow a vegetarian diet, are easily identified, and the diets are not interchangeable. The benefit of the proposed model eliminates the need for dietary intervention prior to the study, which will examine how SO, accumulation of FM and the loss of FFM, develops among children and adolescents with ALL adhering to a vegetarian compared to non-vegetarian diet. Additionally, this study will examine the interaction of physical activity and diet while considering influential variables on the development of SO.
