Comparison of BMI Derived from Parent-Reported Height and Weight with Measured Values: Results from the German KiGGS Study
Anna-Kristin Brettschneider,Ute Ellert,Angelika Schaffrath Rosario
International Journal of Environmental Research and Public Health , 2012, DOI: 10.3390/ijerph9020632
Abstract: The use of parent-reported height and weight is a cost-efficient instrument to assess the prevalence of children’s weight status in large-scale surveys. This study aimed to examine the accuracy of BMI derived from parent-reported height and weight and to identify potential predictors of the validity of BMI derived from parent-reported data. A subsample of children aged 2–17 years (n = 9,187) was taken from the 2003–2006 cross-sectional German KiGGS study. Parent-reported and measured height and weight were collected and BMI was calculated. Besides descriptive analysis, linear regression models with BMI difference and logistic regression models with weight status misclassification as dependent variables were calculated. Height differences varied by gender and were generally small. Weight and BMI were under-reported in all age groups, the under-reporting getting stronger with increasing age. Overall, the proportion for overweight and obesity based on parental and measured reports differed slightly. In the youngest age group, the proportion of overweight children was overestimated, while it was underestimated for older children and adolescents. Main predictors of the difference between parent reported and measured values were age, gender, weight status and parents’ perception of the child’s weight. In summary, the exclusive use of uncorrected parental reports for assessment of prevalence rates of weight status is not recommended.
Validity and predictors of BMI derived from self-reported height and weight among 11- to 17-year-old German adolescents from the KiGGS study

BMC Research Notes , 2011, DOI: 10.1186/1756-0500-4-414
Abstract: Self-reported and measured data were collected from a sub-sample (3,468 adolescents aged 11-17) from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). BMI was calculated from both reported and measured values, and these were compared in descriptive analyses. Linear regression models with BMI difference (self-reported minus measured) and logistic regression models with weight status misclassifications as dependent variables were calculated.Height was overestimated by 14- to 17-year-olds. Overall, boys and girls under-reported their weight. On average, BMI values calculated from self-reports were lower than those calculated from measured values. This underestimation of BMI led to a bias in the prevalence rates of under- and overweight which was stronger in girls than in boys. Based on self-reports, the prevalence was 9.7% for underweight and 15.1% for overweight. However, according to measured data the corresponding rates were 7.5% and 17.7%, respectively. Linear regression for BMI difference showed significant differences according to measured weight status: BMI was overestimated by underweight adolescents and underestimated by overweight adolescents. When weight status was excluded from the model, body perception was statistically significant: Adolescents who regarded themselves as 'too fat' underestimated their BMI to a greater extent. Symptoms of a potential eating disorder, sexual maturation, socio-economic status (SES), school type, migration background and parental overweight showed no association with the BMI difference, but parental overweight was a consistent predictor of the misclassification of weight status defined by self-reports.The present findings demonstrate that the observed discrepancy between self-reported and measured height and weight leads to inaccurate estimates of the prevalence of under- and overweight when based on self-reports. The collection of body perception data and parents' height and weight is t

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0015739
Abstract: We recently showed that in preschoolers risk factors for overweight show stronger associations with BMI in children with high BMI values. However, it is unclear whether these findings might also pertain to adolescents.

BMC Public Health , 2009, DOI: 10.1186/1471-2458-9-46
Abstract: Data were collected in the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), a nationally representative and comprehensive data set on health behaviour and health status of German children and adolescents. Body height and weight were measured and body mass index (BMI) was classified according to IOTF cut-off points. Statistical analyses were conducted on 13,450 non-underweight children and adolescents aged 3 to 17 years. The association between overweight, obesity and several potential determinants was analysed for this group as well as for three socio-economic status (SES) groups. A multiple logistic regression model with obesity as the dependent variable was also calculated.The strongest association with obesity was observed for parental overweight and for low SES. Furthermore, a positive association with both overweight (including obesity) and obesity was seen for maternal smoking during pregnancy, high weight gain during pregnancy (only for mothers of normal weight), high birth weight, and high media consumption. In addition, high intakes of meat and sausages, total beverages, water and tea, total food and beverages, as well as energy-providing food and beverages were significantly associated with overweight as well as with obesity. Long sleep time was negatively associated with obesity among 3- to 10-year olds. Determinants of obesity occurred more often among children and adolescents with low SES.Parental overweight and a low SES are major potential determinants of obesity. Families with these characteristics should be focused on in obesity prevention.The increased prevalence of overweight and obesity among children and adolescents is a severe public health problem across the developed and the developing world [1]. Nationally representative data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) show that in Germany, currently 15% of the 3- to 17-year olds are considered overweight or
The Relation of Sleep, Distress, and Coping Strategies—What Male and Female Students Can Learn from Each Other?  [PDF]

Abstract: Sleep quality, distress, and coping strategies differ between male and female students. However, effects of gender on their relation have not been evaluated. Therefore, the primary aim of this study was to confirm gender differences on sleep quality, chronic distress, and various coping strategies, as well as to examine gender differences in their relation to each other. A cross-sectional online study including several sleep-related self-report measures was completed by 6379 German students. After excluding all cases with missing data on the variables gender, psychiatric disorder, and medication, the final sample consisted of 5889 students with a mean age of 23.10 years (SD = 2.67) for men and 22.64 years (SD = 2.56) for women. Data from the Pittsburgh Sleep Quality Index, the Trier Inventory for Chronic Stress, and the Proactive Coping Inventory were analyzed. Results showed that women reported to have a poorer sleep quality, a higher level of chronic distress, and use social support more often than men. The hypothesized model revealed gender differences on the model level. However, these differences only occurred between avoidance coping and distress, as well as between various coping strategies. The biological gender influenced each of those three variables, but barely their relation to each other. Participants’ gender role might explain gender differences in coping strategies and their impact on distress. Furthermore, the type of stressor and subjective or objective measured sleep parameters might show more gender differences on this relation. Conclusively, gender-specific trainings or interventions are not necessary, however, gender differences should be considered during the implementation process.
Secondary neurons are arrested in an immature state by formation of epithelial vesicles during neurogenesis of the spider Cupiennius salei

Abstract: In contrast to the primary groups, the secondary invaginating cells do not detach from each other after invagination but maintain their epithelial character and form so-called epithelial vesicles. As revealed by dye labeling, secondary neural precursors within epithelial vesicles do not show any morphological features of differentiation indicating that the formation of epithelial vesicles after invagination leads to a delay in the differentiation of the corresponding neural precursors. About half of the secondary neural precursor groups do not dissociate from each other during embryogenesis indicating that they provide neural precursors for larval and adult stages.Secondary neural precursors are arrested in an immature state by formation of epithelial vesicles. This mechanism facilitates the production of larval neural precursors during embryogenesis. I discuss the evolutionary changes that have occured during neural precursor formation in the arthropod group and present a model for the basal mode of neurogenesis.The arthropods form a diverse group with a correspondingly high variation of neural structures adapted to the specialized behaviour and lifestyles of individual species. This raises the question of how developmental processes have been modified during evolution to generate the wide diversity of nervous systems seen in adult arthropods. Evolutionary modifications that lead to variations in neural structures can occur during different processes of neurogenesis. The establishment of neural networks can be influenced by changes in the generation of neural precursors, modifications of cell fates or elimination of individual neurons as well as changes in axonal guidance. A comparative analysis of neurogenesis in chelicerates and myriapods has revealed that although the developmental program is genetically conserved, there is a major difference in the recruitment of neural precursors as compared to insects and crustaceans [1-5]. Groups of neural precursors invagin

Abstract: this article presents general political and economic information about colombia since 2009. in addition, it briefly describes several events that stirred public debate. the article suggests that uncertainty regarding a second reelection of president uribe contributed to some of the uneasiness surrounding the nomination of key public servants, investigations about undue monitoring of political and social leaders by the national intelligence agency, and distribution of agricultural subsidies. the article suggests that this uncertainty affected colombia's relations with its neighbors.
Challenges in Implementing Competency-based English Language Teaching at University Level

TEFLIN Journal , 2004,
Abstract: Competency-based curriculum has been widely implemented by many higher institutions in Indonesia. It is expected that the competency-based curriculum, which puts more emphasis on the needs of job market, prepare students for specified tasks. Competency in a general sense can be seen from the task performance. English language competency is one of the basic competencies which should be acquired by a university graduate in order to enter international market and survive the global competition. The institution which offers English language as part of their curriculum must answer the demand for an English language competent graduate by preparing the best way to teach the language. This article examines the steps to develop a competency-based English language teaching where student's attitude and achievement comprise the important segments of evaluation. It focuses on the challenges, which will probably be faced by the teachers in implementing this competency-based teaching at the university level.

Forum : Qualitative Social Research , 2003,
Abstract: Dieser Text ist rein literarisch und fiktiv. Alle Angaben sind subjektiv, emotional und frei erfunden. Sie sind das kreative Nebenprodukt einer retrospektiven, erinnerungsverzerrten, ganz und gar nicht wissenschaftlichen Besch ftigung mit dem Prozess des Schreibens einer Doktorarbeit. Die Darstellung erlaubt daher keine Rückschlüsse auf tats chlich lebende oder schon verstorbene Personen oder darauf, wie es wirklich war. Erz hlt wird die Geschichte der Psychologin Laura Wolf, die zur Verarbeitung sexualisierter Gewalt in der Kindheit promovieren m chte. Dabei st t sie auf ein Konglomerat von universit tsinternen Konflikten, undurchdringlichen Machtstrukturen, bürokratischen Hindernissen und pers nlichen Eitelkeiten, die durch die Reaktionen, die das Promotionsthema selbst ausl st, noch verst rkt werden. URN: urn:nbn:de:0114-fqs0302171 This is a fictional text. It is the creative by-product of writing a doctoral thesis and a retrospective, memory distorted, and entirely non-academic reflection of this process. All statements are subjective, emotional and purely fictitious. Therefore, this description does not allow any conclusions about real persons or events in the present or in past times. No similarity to persons, either living or dead is intended. This is the story of the psychologist Laura Wolf, who tries to obtain her doctorate studying the recovery processes of victims of sexual violence during childhood. Laura is confronted with a variety of conflicts within the university, rigid power structures, which cannot be overcome, bureaucratic obstacles, and personal vanity. These barriers are amplified by individual reactions to her thesis topic. URN: urn:nbn:de:0114-fqs0302171 Este es un texto literario. Es el subproducto creativo al escribir una tesis doctoral y la retrospectiva, memoria distorsionada y reflexión no del todo académica de ese proceso. Todos los extractos son subjetivos, emocionales y puramente ficticios. Por lo tanto, esta descripción no permite conclusiones acerca de las personas reales o de los hechos en el presente o el pasado. Esta es la historia de la psicóloga Laura Wolf, quien intenta obtener su doctorado estudiando el proceso de recuperación en víctimas de violencia sexual durante la infancia. Laura se enfrenta con un conglomerado de conflictos dentro de la universidad, con estructuras de poder rígidas que no pueden superarse, obstáculos burocráticos y vanidades personales. Esas barreras se ven amplificadas por las reacciones personales al tópico de su tesis. URN: urn:nbn:de:0114-fqs0302171
