Increased consumption of sweetened beverages has previously been linked to the degree of childhood obesity.The aim of the present study was to assess whether the intake of sweetened beverages, candy, snacks or fast food at baseline in a multidisciplinary childhood obesity treatment program was associated with the baseline degree of obesity or the treatment effect.This prospective study included 1349 overweight and obese children (body mass index standard deviation scores (BMI SDS) ≥ 1.64) enrolled in treatment at The Children's Obesity Clinic, Copenhagen University Hospital Holbaek. The children were evaluated at baseline and after up to 5.9 years of treatment (median 1.3 years).Both boys and girls decreased their BMI SDS during treatment with a mean decrease in boys of 0.35 (p 0.0001) and in girls of 0.22 (p 0.0001) after 1 year of treatment. There were no associations between the baseline intake of sweetened beverages, candy, snacks, and/or fast food and BMI SDS at baseline or the change in BMI SDS during treatment.The intake of sweetened beverages, candy, snacks or fast food when entering a childhood obesity treatment program was not associated with the degree of obesity at baseline or the degree of weight loss during treatment.

What is already known about this subject • Investigations of non-alcoholic fatty liver disease (NAFLD) by non-invasive imaging procedures have limited evidence. • Thirty percent of obese children are estimated to have NAFLD and implications for future morbidity are uncertain. What this study adds • Many obese children and youths exhibit a high liver fat content as examined by magnetic resonance spectroscopy. • Associations between liver fat content, anthropometry, abdominal adipose tissue distribution and liver enzymes are illustrated.The study aims to investigate the degree of hepatic steatosis and associations with the amount of abdominal subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), anthropometric data and biochemical measures of liver enzymes in children and youths included in obesity treatment. The study included 164 patients, aged 6-20 years, with a body mass index (BMI) above the 90th percentile for sex and age. Liver fat content was measured by magnetic resonance spectroscopy (MRS). SAT and VAT were measured by magnetic resonance imaging. Hepatic steatosis was defined as liver fat content5% (steatosis-5%) and 9% (steatosis-9%), respectively. Data on waist circumference (WC) and blood samples were available in 124 patients. Steatosis-5% and steatosis-9% were identified in 45% and 27% of the patients, respectively. These patients had increased SAT, VAT, BMI standard deviation score, WC/height ratio, alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT) levels. GGT, ALT and VAT were found to be independent risk factors of hepatic steatosis. In this study, a substantial proportion of obese children and youths have hepatic steatosis. Therefore, it is important to examine these subjects for the degree of fat in their liver. Future studies focusing on hepatic steatosis should consider the use of MRS in addition to blood samples.
