Pediatric obesity is one of the most important health issues facing the world today. Changing lifestyles, affluence on the rise, introduction to new diets, changing social order and an increasingly sedentary lifestyle of the youth have contributed to the alarming rise of child and adolescent obesity. Recent definitions of obesity by WHO and IOTF have afforded distinct cutoffs to determine prevalence of obesity at the community level in children. Newer insights into leptin and its signaling pathways have helped our understanding of the genesis of obesity, which has been further bolstered by the numerous studies into the genetics of obesity. Endocrine disorders like hypothyroidism, Cushing's syndrome, and syndromic disorders need to be ruled out. In addition to the routine investigations, evaluation of markers of insulin resistance and fat percentage is of great research utility In Indian children, who differ metabolically from children in the west. The cornerstones of treatment are therapeutic lifestyle changes, behavior modification and pharmacological therapy when needed. However, primordial prevention by inculcation of a healthy lifestyle seems to be the best bet in combating pediatric obesity.

Abstract
BACKGROUND: The safety of 2-h preoperative clear liquid fasts has not been established for overweight/obese pediatric day surgical patients. Healthy children and obese adults who fasted 2 h have small residual gastric fluid volumes (GFVs), which are thought to reflect low pulmonary aspiration risk. We sought to measure the prevalence of overweight/obesity in our day surgery population. We hypothesized that neither body mass index (BMI) percentile nor fasting duration would significantly affect GFV or gastric fluid pH. In children who were allowed clear liquids up until 2 h before surgery, we hypothesized that overweight/obese subjects would not have increased GFV over lean/normal subjects and that emesis/pulmonary aspiration events would be rare. METHODS: Demographics, medical history, height, and weight were recorded for 1000 consecutive day surgery patients aged 2-12 yr. In addition, 1000 day surgery patients (age 2-12 yr) undergoing general endotracheal anesthesia were enrolled. After tracheal intubation, a 14-18F orogastric tube was inserted and gastric contents evacuated. Medications, fasting interval, GFV, pH, and emetic episodes were documented. Age- and gender-specific Center for Disease Control and Prevention growth charts (2000) were used to determine ideal body weight (IBW = 50th percentile) and to classify patients as lean/normal (BMI 25th-75th percentile), overweight (BMI > or = 85th to <95th percentile), or obese (BMI > or = 95th percentile). RESULTS: Of all day surgery patients, 14.0% were overweight and 13.3% were obese. Obese children had lower GFV per total body weight (P < 0.001). When corrected for IBW, however, volumes GFV(IBW) were identical across all BMI categories (mean 0.96 mL/kg, sd 0.71; median 0.86 mL/kg, IQR 0.96). Preoperative acetaminophen and midazolam contributed to increased GFV(IBW) (P = 0.025 and P = 0.001). Lower GFV(IBW) was associated with ASA physical status III (P = 0.024), male gender (P = 0.012), gastroesophageal reflux disease (P = 0.049), and proton pump inhibitor administration (P = 0.018). GFV(IBW) did not correlate with fasting duration or age. Decreased gastric fluid acidity was associated with younger age (P = 0.005), increased BMI percentile (P = 0.036), and African American race (P = 0.033). Emesis on induction occurred in eight patients (50% of whom were obese, P = 0.052, and 75% of whom had obstructive sleep apnea, P = 0.061). Emesis was associated with increased ASA physical status (P = 0.006) but not with fasting duration. There were no pulmonary aspiration events. CONCLUSIONS: Twenty-seven percent of pediatric day surgery patients are overweight/obese. These children may be allowed clear liquids 2 h before surgery as GFV(IBW) averages 1 mL/kg regardless of BMI and fasting interval. Rare emetic episodes were not associated with shortened fasting intervals in this population.
