The increasing overweight and obesity prevalence among children and adolescents may not only result in life quality prejudice but also increase obesity indexes at adult age. Perinatal factors such birthweight (BW) as well as socioeconomic factors (SES) and cardio respiratory fitness (CRF) have shown different associations with adolescents’ obesity level. Thus, the aims of the present study were to describe the prevalence of overweight/obesity (Ov/ Ob) and, to evaluate the associations of BW, SES and CRF on adolescents body mass index (BMI).info:eu-repo/semantics/publishedVersio

The 4th Scandinavian Pediatric Obesity ConferencePoster PresentationsTRACK 1: EpidemiologyT1:PO.01Trends in overweight and obesity among childrenfrom Jena, GermanyKromeyer-Hauschild KInstitute of Human Genetics and Anthropology, UniversityHospital, Jena, GermanyIntroduction: Trends in the prevalence of overweight and obesity inJena children (Germany) were assessed between 1975 and 2005/2006. In addition changes in body composition were investigatedand factors related to these changes should be identified.Methods: The analyses were based on cross-sectional school-basedsurveys in 7- to 14-year-old children performed in Jena 1975, 1985,1995 and 2005/2006. Overweight and obesity were estimated byGerman and IOTF reference data. Body composition was assessed byskinfold thickness. Household questionnaires were performed to getadditional information about the parents (parental education andemployment status, overweight), meal patterns, and physical activity.Using linear and logistic regression analysis the association of thesefactors with weight status and body composition was analysed.Results: Between 1985 and 2005/2006 the prevalence of overweightand obesity increased significantly in both sexes, whereas non-signifi-cant changes were found between 1975 and 1985. Parallel to theincrease in BMI, there has been a clear increase in the subcutaneousfat mass. Changes in fat mass were found even if BMI remainunchanged, indicating changes in body composition. Multivariateanalyses showed that parental weight status, and low-educationallevel of the parents as well as television watching, and low meal fre-quency were associated with higher BMI-values and higher fat mass.Conclusions: Prevention programmes to establish a healthy andactive lifestyle are necessary to prevent the initial development ofabnormal fat gain. The close involvement of parents in any strategyis essential.Conflict of interest: None disclosed.Funding: No funding.T1:PO.02Influence of birthweight, socioeconomic status,cardio-respiratory fitness in body mass indexVale S, Soares-Miranda L, Santos R, Moreira C, Marques AI,Santos PC, Aleixo I and Mota JFaculty of Sport of University of Porto Research Centre inPhysical Activity, Health and LeisureIntroduction: The increasing overweight and obesity prevalenceamong children and adolescents may not only result in life qualityprejudice but also increase obesity indexes at adult age. Perinatal fac-tors such birthweight (BW) as well as socioeconomic factors (SES)and cardio respiratory fitness (CRF) have shown different associa-tions with adolescents’ obesity level. Thus, the aims of the presentstudy were (1) to describe the prevalence of overweight/obesity (Ov/Ob) and, (2) to evaluate the associations of BW, SES and CRF onadolescents body mass index (BMI).Methods: The sample comprised 2328 adolescents aged from 10 to18 years old, from Portugal. BMI Z score adjusted for age and gen-der were used to categorize normal weight (NW), versus Ov/Ob(those with 1 standard desviation or more were categorized asoverweight/obese). CRF was obtain from the 20 m shuttle run testby Fitness Gram’s battery. Maternal education used to define socio-economic status (SES). BW was assessed by parents’ questionnaireand was divided in: normal BW (NBW), low BW (LBW) and highBW (HBW), according to CDC cut offs. Logistic regression was per-formed to assess the associations between BW, SES and CRF withBMI.Results: We found an Ov/Ob prevalence of 13.4%. Adolescents withLow CRF (OR = 5.3), high BW (OR = 1.7) and low SES (OR = 1.4)were more likely to be classified as OV/OB than those with normalCRF values, normal BW and middle SES.Conclusion: We found negative associations between Low CRF,HBW and Low SES and BMI in our sample.T1:PO.03Ethnic differences in the relationship between bodymass index and percent body fat among AsianchildrenLiu A1,2, Ma G2, Kijboonchoo K3, Ismail MN4, Nasreddine L5,Trinidad TP6, Byrne NM1 and Hills AP11Institute of Health and Biomedical Innovation, QueenslandUniversity of Technology, Brisbane, Australia; 2NationalInstitute for Nutrition and Food Safety, Chinese Center forDisease Control and Prevention, Beijing, China; 3Institute ofNutrition, Mahidol University at Salaya, Nakhon Pathom,Thailand; 4Universiti Kebangsaan Malaysia, Kuala Lumpur,Malaysia; 5Department of Nutrition and Food Sciences,American University of Beirut, Beirut, Lebanon 6Department ofScience and Technology, Food and Nutrition ResearchInstitute, Manila, PhilippinesIntroduction: Body mass index (BMI) is often used as the surrogatefor body fat to define obesity; however, the approach has limitations.The aim of the study was to determine the effect of ethnicity on theBMI-percent body fat (%BF) relationship among Asian children fromdifferent origins.Methods: Height, weight, and %BF (determined from TBW usingthe deuterium dilution technique) was assessed in 531 boys and 506girls aged 8–10 years. The WHO growth reference (2007) was usedto define obesity. Analysis of covariance was employed to comparedifferences in %BF among ethnic groups, with gender, age and BMIas covariates.Results: There was an interaction between BMI and ethnicity in thiscohort. Normal-weight Malay (23.3 ± 0.5%) and Filipino(23.2 ± 0.7%) children had a higher %BF than Chinese(21.3 ± 0.4%), Lebanese (21.0 ± 0.6%), and Thai (20.7% ± 0.5)children. Overweight Malay children (36.0 ± 1.6%) had a signifi-cantly higher %BF than the other four ethnic groups. There was nosignificant ethnic difference in the BMI-%BF relationship amongoverweight Chinese (31.6 ± 0.5%), Lebanese (32.2 ± 0.9%), Filipino(30.1 ± 1.5%), and Thai children (29.7 ± 0.9%) except that the Leb-anese had a higher %BF than Thais. Further, obese Filipinos(35.1 ± 0.8%) and Thais (35.5 ± 0.8%) had a lower %BF than Chi-nese (39.1 ± 0.7), Lebanese (40.6 ± 0.3%), and Malay children(39.5 ± 1.1%).Conclusions: Ethnicity has an effect on the BMI-%BF relationshipamong Asian children from different origins which varies across theBMI range. These differences should be taken into account whendeveloping BMI cut-offs to define obesity.Conflict of interest: None disclosed.Funding: This project was funded by the International AtomicEnergy Agency (Project Code: RAS/6/050).ª 2010 The AuthorsJournal Compilation ª 2010 The International Association for the Study of Obesity. obesity reviews 11 (Suppl. 1) (2010) 1–47272 obesity reviews____________________________________________________________________________________ 1467789x, 2010, s1, Downloaded from https://onlinelibrary.wiley.com/doi/10.1111/j.1467-789X.2010.00763_7.x by Estsp Politecnico Do Porto, Wiley Online Library on [28/10/2022].

Data were collected from October2009 to May 2009 from 10 regions of Greece. Body weight, height,waist circumference and percentage of body fat and was measuredby trained staff.Results: The students participation rate was 84.9%. The resultantsample consisted of 4876 children (49.3% males and 50.7%females). According to the International Obesity Task Force (IOTF)cut-offs, the overall prevalence of overweight was 29% (95% confi-dence intervals 27.7–30.2) and the rate of obesity was 11.2% (95%confidence intervals 10.3–12.1). When we defined obesity using thegrowth curves of the CDC, the overall prevalence was significantlyhigher and reached 18.1% (95% confidence intervals 17.0–19.1).Additionally, there was a gender difference concerning the preva-lence of obesity with males showing higher percentages. When com-paring the overweight and obesity prevalence (IOTF cut-offs)between urban and rural regions no significant differences werefound. Moreover, no differences were found between different agegroups concerning obesity prevalence, for both genders.Conclusion: The present national survey confirms previous studiesshowing a significant increase in the prevalence of overweight andobesity during the last two decades. These findings suggest a commu-nity as well as individual interventions in all areas of the country.Conflict of interest: None disclosed.Funding: Research relating to this abstract was funded by GeneralSecretariat of Consumers-Greek Ministry of Development, HellenicAssociation of Food and Beverage Companies, Coca Cola Hellas,Coca Cola Hellenic Bottling Company, CPH, FAGE S.A., UnileverHellas, Nestle Hellas, Kraft Foods Hellas.T4:PO.380Gestational weght gain and body mass index inpre-school childrenSantos PC1, Vale S2, Santos R2, Moreira C2, Marques AI2,Soares-Miranda L2 and Mota J21School of Health Technology of Porto – Portugal; 2ResearchCentre for Physical Activity, Health and Leisure, Faculty ofSports Science. University of Porto - PortugalAim: To examine the association between gestational weight gain(GWG) and body mass index (BMI) in pre-school children.Methods: The study comprised a total of 281 children (55.9% boys)aged 4–6 years. GWG were assessed by questionnaire. We measuredweight and height, and BMI was calculated. Children were catego-rized as non-overweight (NOW) and overweight/obese (OW) accord-ing to the sex-adjusted BMI z-score (<1 and ‡1, respectively).Potential confounders were assessed by questionnaire and included:Mother’s education and BMI, birth weight and BMI of the first twoyears and maternal smoking during pregnancy, time spent watchingtelevision, and playing video-games and sleeping time. Physical activ-ity was measured by accelerometer.Results: We found that 30.3% of women had excessive GWG. Theprevalence of overweight was 14.6% in children. Reporting resultsof stepwise multiple logistic regression model, adjusted for BMI atfirst and second years of life, physical activity and mother obesity(P £ 0.05 all of them), showed that children whose mothers classifiedas excessive GWG (OR = 4.0; 95%CI: 1.6–10.3; P = 0.004) weremore likely to be classified as OW compared to mothers classifiednormal GWG.Conclusion: Our data suggested that excessive GWG was a strongpredictor of OW at pre-school age after adjustment for potentialconfounders.T4:PO.381Preadolescent overweight - a risk factor for laterweight misperceptionTrolle-Lagerros Y1, Galanti MR1, Caria MP1,2 andBellocco R1,31Karolinska Institutet, Stockholm, Sweden; 2AvogadroUniversity, Novara, Italy; 3University of Milano-Bicocca, Milano,ItalyIntroduction: Adolescents’ perception of overweight often disagreeswith objective measurements. However, whether factors explainingthis discrepancy are potentially modifiable is unclear.Methods: We analyzed data from 2001 Swedish adolescents (1026females and 975 males) who self-reported anthropometric measures(height and weight) and body size perception at 15 and 17 years ofage. Misperception of overweight was defined as overestimation ofbody size in relation to the estimated Body Mass Index (BMI, kg/m2)in two categories (not overweight, or overweight+obese). BMI mea-sured by the school nurse at 11 years, school-based education onnutrition/physical activity, smoking, alcohol consumption, physicalactivity and indicators of healthy/unhealthy eating were examined aspotential predictors or correlates of overweight misperception inmultivariate logistic regression models. Adjusted odds ratios (OR)and 95% confidence intervals (CI) were used as measures of associa-tion.Results: At 15 years, 32% of girls and 10% of boys misclassifiedthemselves as overweight. In both genders, misperception of over-weight was predicted by overweight at 11 years (OR = 2.3 CI:1.4–3.6 in boys, OR = 1.9, CI:1.3–2.8 in girls). Among girls, smokingwas associated with a higher risk of misperception (OR = 1.6,CI:1.2–2.2). Among boys, frequent physical activity (>6 hours/week)was associated with a lower risk of misperception (OR = 0.4, CI:0.2–0.7). No association with misperception was observed withschool-based education on nutrition/physical activity.Conclusion: This study reveals that being overweight at 11 years is astrong predictor for misperception of overweight during teenageyears. Preventing overweight in pre-adolescence and/or promotingphysical activity may be efficient ways to avoid later unjustifiedweight concerns.Conflict of interest: None.Funding: Research relating to this abstract was funded by StockholmCounty Council and the Swedish Research Council.ª 2010 The AuthorsJournal Compilation ª 2010 The International Association for the Study of Obesity. obesity reviews 11 (Suppl. 1) (2010) 1–472obesity reviews Posters: Epidemiology, Diet, Activity and Behaviour 413____________________________________________________________________________________ 1467789x, 2010, s1, Downloaded from https://onlinelibrary.wiley.com/doi/10.1111/j.1467-789X.2010.00763_7.x by Estsp Politecnico Do Porto, Wiley Online Library on [28/10/2022].
