  • 1. Alcohol consumption is related to abdominal obesity in adolescentboys, but not in girls, in the Greek populationC. Loupa, M. Kaklamanou, D. Kaklamanou, L. Lanaras, E. Kapantais Hellenic Medical Association for Obesity (HMAO) Athens, Greece Data from 1st national epidemiological large scale survey on the prevalence of abdominal obesity in Greece
  • 2. Introduction - 1 The metabolic syndrome (syndrome X) is characterised by : Abdominal obesity Dyslipidemia Hyperinsulinemia-glucose intolerance Hypertension Waist-to-hip ratio (WHR) is considered more reliable than body mass index (BMI) in estimating abdominal obesity, which is considered as part of the metabolic syndrome. Hellenic Medical Association for Obesity (HMAO) 1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 3. Cut-off points of Waist-to-Hip ratio <0.95: low risk95-1.00: moderate risk For men >1.00: increased risk <0.80: low risk For0.80-0.85: moderate risk women >0.85m: increased risk http://eiep.gr
  • 4. Introduction - 2 Chronic alcohol consumption has many adverse effects (all major organs can be affected: nervous system, cardiovascular system, liver, GI system, pancreas, hematopoietic system, endocrine system)  Moderate drinking may have some health benefits (reducing the risk of cardiovascular disease – “the French paradox”)Hellenic Medical Association for Obesity (HMAO),1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 5. Aim To explore a potential relation of alcohol consumption to abdominal obesity in adolescents in Greece.Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 6. Subjects The present study is part of the first national epidemiological large scale survey on the prevalence of obesity in Greece, conducted by the Hellenic Medical Association for Obesity (HMAO).Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 7. First national epidemiologicalsurvey on the prevalence of obesity in Greece A nationwide, cross-sectional epidemiological study, conducted from February 2003 to June 2003, designed to estimate obesity prevalence in the Greek population.Hellenic Medical Association for Obesity (HMAO)First National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 8. First national epidemiological survey on the prevalence of obesity in Greece Secondary schools throughout Greecewere randomly chosen. Gym teachers were trained onanthropometric techniques. Students 13-19 years old had directmeasurements at the schools by theteachers.Hellenic Medical Association for Obesity (HMAO)First National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 9. First national epidemiological survey on the prevalence of obesity in Greece Instructions were given to children formeasurements of their family members,which we were done at home. Data regarding socioeconomic status,dietary and drinking habits, physicalactivity, smoking habits, etc. wascollected by a questionnaire filled bythe students and all the members oftheir household.Hellenic Medical Association for Obesity (HMAO)First National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 10. Methods - 1  WHR (waist-to-hip ratio) was calculated from waist and hip circumference (cm)  The following categories were used: Boys Girls Normal <1.00 <0.85 Abnormal >1.00 >0.85Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 11. Methods - 2 Alcohol consumption was calculated by adding number of units consumed weekly, multiplied by alcohol comprehensiveness of each beverage. Subjects were divided to: non drinkers (abstainers) <50 mg/week 51 - 150 mg/week 151 - 300 mg/week >300 mg/week Hellenic Medical Association for Obesity (HMAO) 1st Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 12.  Just a moderate drinker (10g/day)!!!!
  • 13. Methods - 3 SPSS version 11.5 was used for statistical analysis  Comparisons were made by Student’s t-test and non-parametric tests.Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 14. Results12500 adolescents(5808 boys, age 15.2+1.7 and 6692 girls, age 14.6+0.9 years)were included in this study. WHR was 0.89+0.31 and 0.82+0.24 in boys and girls, respectively.Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece

  • 19. Results In boys, WHR was associated to alcohol consumption (p=0.006, Kendall’s tau-b). On the contrary, this was not the case with girls (p=0.098, NS).Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece

  • 21. Conclusions
  • 22. Conclusions - 1 In the Greek population, adolescent boys drink more alcohol than girls. 4% of adolescent boys and less than 1% of adolescent girls are heavy drinkers (>150 g/week)Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
  • 23. Conclusions - 2 Anthropometry showed that boys are more likely to have normal WHR than girls. Contrary to the effects of alcohol consumption to risk factors of various diseases, alcohol is inversely related to abdominal obesity in moderate drinking boys, but not in girls.Hellenic Medical Association for Obesity (HMAO)1st National Epidemiological Large Scale Survey on the Prevalence of Obesity in Greece
