    Introduction: Children’s obesity is a known health problem in the world and is a strong predictor of obesity in adulthood which increases the incidence of related diseases such as metabolic syndrome. According to the MONIKA project by the World Health Organization (WHO), Iran is one of the seven countries with a high rate of child obesity. Fatty liver is an abnormality related to metabolic syndrome, with higher prevalence in obese children according to some previous studies. This study investigates the presence of Sonographic Fatty Liver (SFL) in Iranian obese children in comparison with normal and overweight children. Material and methods: This was a cross-sectional study on 962 randomly selected children between the ages of 6 to 18 years. The subjects were divided into three groups of normal, overweight and obese based on body mass index (BMI). A questionnaire including demographic and anthropometric characteristics was filled for each one. To detect the presence of SFL all the subjects underwent assessments with ultrasonography by radiologist who was not aware of their BMI. The incidence of SFL was determined based on the ultrasonographic diagnosis criteria. Results: The average age of the children in the study was 12.59 ± 3.25 years. The mean of the liver span in the normal, overweight and obese groups were 111.36 ± 18.73, 121.18 ± 16.63 and 118.21 ± 19.15 respectively. The prevalence of SFL in obese children was 54.4%, which was significantly higher than overweight (10.5%) and normal ones (1%). According to present results, there was no significant difference in prevalence of SFL between sexes. Conclusions: The high rate of detected SFL in obese children in this study suggests that Iranian obese children are at risk of metabolic syndrome. Moreover, the WHO indicated Iran as one of the countries with high rate of obese children. Based on this information, we can conclude that the prevalence of metabolic syndrome and its related non-communicable diseases will be increasing future in . Therefore, it is necessary to develop some plan to control overweight problem including teaching healthy lifestyle in schools and kindergartens as well as mass media.Wst臋p: Oty艂o艣膰 u dzieci jest znanym na 艣wiecie problemem zdrowotnym oraz silnym czynnikiem prognostycznym wyst膮pienia oty艂o艣ci w wieku doros艂ym, kt贸ra zwi臋ksza cz臋sto艣膰 chor贸b jej towarzysz膮cych, takich jak zesp贸艂 metaboliczny. Wed艂ug projektu 艢wiatowej Organizacji Zdrowia (WHO, World Health Organization) MONIKA Iran jest jednym z siedmiu kraj贸w o du偶ym odsetku dzieci oty艂ych. St艂uszczenie w膮troby jest zaburzeniem towarzysz膮cym zespo艂owi metabolicznemu, zgodnie z wynikami niekt贸rych wcze艣niejszych bada艅, cz臋sto wyst臋puj膮cym u oty艂ych dzieci. W niniejszej pracy badano obecno艣膰 ultrasonograficznie rozpoznanego st艂uszczenia w膮troby (SFL) w populacji oty艂ych dzieci ira艅skich w por贸wnaniu z grup膮 dzieci z nadwag膮 i prawid艂ow膮 mas膮 cia艂a. Materia艂 i metody: Niniejsze badanie przekrojowe przeprowadzono w grupie 962 losowo wybranych dzieci w wieku 6-18 lat. Badani zostali podzieleni wed艂ug wska藕nika masy cia艂a (BMI) na trzy grupy: o prawid艂owej masie cia艂a, z nadwag膮 i na grup臋 dzieci oty艂ych. W przypadku ka偶dego uczestnika wype艂niano kwestionariusz zawieraj膮cy charakterystyk臋 demograficzn膮 i antropometryczn膮. U wszystkich uczestnik贸w dla wykrycia SFL wykonywano badanie ultrasonograficzne przeprowadzane przez radiologa, kt贸ry nie zna艂 BMI badanych. Cz臋sto艣膰 SFL ustalano na podstawie ultrasonograficznych kryteri贸w diagnostycznych. Wyniki: 艢redni wiek dzieci uczestnicz膮cych w badaniu wynosi艂 12,59 ± 3,25 roku. 艢rednie wymiary pionowe w膮troby wynosi艂y: 111,36 ± 18,73, 121,18 ± 16,63 i 118,21 ± 19,15 mm odpowiednio w grupach dzieci z prawid艂ow膮 mas膮 cia艂a, z nadwag膮 i oty艂ych. Cz臋sto艣膰 wyst臋powania SFL u dzieci oty艂ych wynosi艂a 54,4%, co by艂o warto艣ci膮 istotnie wy偶sz膮 w por贸wnaniu z grup膮 dzieci z nadwag膮 (10,5%) i prawid艂ow膮 mas膮 cia艂a (1%). Wed艂ug wynik贸w tego badania nie by艂o znamiennych r贸偶nic w cz臋sto艣ci wyst臋powania SFL mi臋dzy p艂ciami. Wnioski: Du偶y odsetek SFL wykrywanego u dzieci oty艂ych w tym badaniu sugeruje, 偶e ira艅skie oty艂e dzieci obci膮偶one s膮 ryzykiem wyst膮pienia zespo艂u metabolicznego. Co wi臋cej, WHO okre艣la Iran jako jeden z kraj贸w o du偶ym odsetku dzieci oty艂ych. Opieraj膮c si臋 na tych informacjach, mo偶na wysun膮膰 wniosek, 偶e cz臋sto艣膰 wyst臋powania zespo艂u metabolicznego i zwi膮zanych z nim chor贸b niezaka藕nych b臋dzie si臋 zwi臋ksza膰 w przysz艂o艣ci. Dlatego konieczne jest opracowanie okre艣lonego planu dla kontroli problemu nadwagi, uwzgl臋dniaj膮cego nauczanie zdrowego stylu 偶ycia w szko艂ach, przedszkolach i 艣rodkach masowego przekazu

    <p>Abstract</p> <p>Objectives</p> <p>This study aimed to determine the prevalence of the metabolic syndrome, abnormalities of liver enzymes and sonographic fatty liver, as well as the inter-related associations in normal weight, overweight and obese children and adolescents.</p> <p>Methods</p> <p>This cross-sectional study was conducted among a sample of 1107 students (56.1% girls), aged 6-18 years in Isfahan, Iran. In addition to physical examination, fasting blood glucose, serum lipid profile and liver enzymes were determined. Liver sonography was performed among 931 participants. These variables were compared among participants with different body mass index (BMI) categories.</p> <p>Results</p> <p>From lower to higher BMI category, alanine aminotransferase (ALT), total cholesterol, LDL-cholesterol, triglycerides and systolic blood pressure increased, and HDL-cholesterol decreased significantly. Elevated ALT, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were documented in respectively 4.1%, 6.6% and 9.8% of normal weight group. The corresponding figure was 9.5%, 9.8% and 9.1% in overweight group, and 16.9%, 14.9% and 10.8% in obese group, respectively. In all BMI categories, ALT increased significantly by increasing the number of the components of the metabolic syndrome. Odds ratio for elevated liver enzymes and sonographic fatty liver increased significantly with higher number of the components of the metabolic syndrome and higher BMI categories before and after adjustment for age.</p> <p>Conclusions</p> <p>Because of the interrelationship of biochemical and sonographic indexes of fatty liver with the components of the metabolic syndrome, and with increase in their number, it is suggested to determine the clinical impact of such association in future longitudinal studies.</p
