“…This finding is in accordance with other studies about mothers' perception of their children's obesity, expressing the dominant belief that their children's body size and the growth standard are fixed or predestined by hereditary factors and, hence, that they cannot be changed (11)(12) .…”

The objective was to explore obese adolescents' perceptions about obesity among students in the seventh to ninth grade of a public school in Tamaulipas, Mexico. This is a qualitative study. Participants were 24 adolescents with a body mass index equal to or greater than the 95th percentile. Semistructured interviews were conducted until data saturation was reached and the meaning was understood. The adolescents defined obesity according to standards of measurement. They identified the hereditary factor as the main obesity cause, tended to underestimate obesity and had low self-esteem. They reported problems to do physical exercise and get clothes in order to improve their image, and feel rejected by their peers in school. It was identified that these adolescents have psychological defense mechanisms against obesity and that some of them are making efforts to lose weight.Obesity entails social and psychological health implications for persons suffering from this problem. Interventions should be put in practice.Descriptors: Adolescent; Obesity; Body Weight; Self Concept. para subestimar a obesidade e a ter baixa autoestima, apresentan problemas quando realizam atividade física e para conseguirem roupas para melhorar a própria imagen, são rejeitados pelos seus pares ou iguais, na escola.

Percepciones de la obesidad de adolescentes obesos estudiantes del 7º al 9º grado residentes en Tamaulipas, MéxicoEl objetivo de esta investigación fue explorar las percepciones de la obesidad de adolescentes obesos estudiantes del 7º al 9º grado de una institución pública en Tamaulipas, México. Se trata de un estudio cualitativo en el cual participaron 24 adolescentes que tenían un índice de masa corporal superior al percentil 95. Se realizaron entrevistas semiestructuradas hasta obtener la saturación de los datos y la comprensión del significado. Los adolescentes definieron la obesidad de acuerdo a los estándares de medición, identificaron como causa principal el factor hereditario, tendieron a subestimar la obesidad y presentaron baja autoestima, relataron problemas cuando realizan actividad física y para conseguir ropa que pudiese mejorar su imagen, y se sienten rechazados por sus pares o iguales en la escuela. Se identificó que cuentan con mecanismos psicológicos de defensa ante la obesidad y algunos de ellos están realizando acciones para disminuir el peso. La obesidad tiene implicaciones en la salud, también en los aspectos psicológico y social de quienes la padecen. Se recomienda implementar intervenciones.

“…On the other hand, the cross-sectional nature of these surveys cannot identify any causal factors for increasing overweight and obesity; but whatever the reasons, the condition is continuing to rise in adolescents from NI. It is well documented that obesity in childhood and adolescence tends to track into adulthood (8,9) along with adverse dietary and physical behaviours known to promote obesity (37)(38)(39) . Obesity and accompanying dietary and physical behaviours are predictors of adult morbidity and mortality, in the form of CVD and diabetes which are major public health burdens (5,6,40) .…”

Objective: To report trends in underweight, overweight and obesity in 12-15-year-old adolescents and examine changes in dieting behaviour, which have been less well documented. Design: Comparison of two independent representative cross-sectional surveys. Setting: Northern Ireland. Subjects: Weight and height were objectively measured in 1324 boys and 1160 girls in 1996 and 1274 boys and 1374 girls in 2007. Participants reported whether they were following any particular diet including a self-proposed or prescribed weight-reduction diet. Results: Overweight and obesity increased in girls from 15 % to 23 % and 2 % to 6 %, respectively. Increases were more modest in boys with overweight increasing from 13 % to 18 % and obesity from 3 % to 6 %. The proportion of underweight adolescents decreased from 9 % to 6 % in girls and 8 % to 5 % in boys. Evidence of social disparity was observed in girls from a manual socio-economic background, with overweight/obesity prevalence rates increasing from 21 % to 36 % compared with 15 % to 26 % in girls from a non-manual background. Despite these trends fewer adolescents, in particular girls, reported following weight-reduction diets (14 % of overweight/obese girls in 2007 v. 21 % in 1996; 8 % of boys in 2007 v. 13 % in 1996). Of these girls, the proportion from a manual background following weight-reduction diets decreased from 25 % to 11 %. Conclusions: Overweight and obesity are continuing to increase in adolescents despite government and media awareness strategies. There also appears to be reduced dieting behaviour, despite increasing body weight, particularly in girls from manual socio-economic backgrounds.

Fundamento: La creciente preocupación por la salud ha suscitado un enorme interés en el estudio de los factores que inciden sobre ella. El objetivo de este trabajo es analizar la influencia del nivel de actividad física (NAF) en la salud de los adolescentes y determinar su relación con la presión arterial (PA) y la composición corporal.Métodos: La investigación se realizó entre noviembre de 2002 y febrero de 2003 utilizando el Cuestionario Modificable de Actividad Física para Adolescentes que mide el nivel de actividad física. También se midieron la composición corporal y la presión arterial, en una muestra compuesta por 554 adolescentes de 35 centros educativos de Madrid, con edades comprendidas entre 12 y 18 años. Resultados:Resultaron inactivos el 13,2% de los varones y el 36,4% de las mujeres. Los promedios para las PA sistólica/diastólica fueron de 125,6/71,3 mmHg en los varones y 118/69,4 mmHg en las mujeres, pero sólo se detectó influencia del nivel de actividad física en la PA diastólica para los varones. Presentaron tendencia al sobrepeso el 48,27% de las mujeres frente al 13,53% de los hombres. En el caso de las mujeres se encontró relación entre adiposidad corporal y nivel de actividad física.Conclusiones: El nivel de actividad física se presenta como un factor asociado a la salud de los adolescentes, si bien se manifiesta de forma distinta en cada sexo. En los hombres afecta significativamente a la PA diastólica, mientras que en las mujeres su influencia se detecta en el grado de adiposidad corporal. ABSTRACT Relationship of the Degree of Physical Activity, Blood Pressure and Body Fat among Teenagers in MadridBackground: It is throughout childhood and adolescence that many behavior patterns which are going to have a powerful influence on health during adult life are established. This study is aimed at analysing the influence physical activity has on the health of adolescents and at determining the relationship thereof with blood pressure (BP) and body composition. Methods:The research was conducted from November 2002 to February 2003, using the Modifiable Physical Activity Questionnaire for Adolescents, which measures the degree of physical activity. The anthropometric variables and blood pressure were also measured for the sample comprised of 554 adolescents within the 12-18 age range from 35 schools in Madrid.Results: A total of 13.2% of the males and 36.4% of the females were found to be inactive. The averages for the systolic/diastolic BP were 125.6/71.3 mmHg in the males and 118/69.4 mmHg in the females, but physical activity was found to have an influence solely on the diastolic BP for the males. A total of 48.27% of the females showed a tendency toward being overweight, as compared to 13.53% of the males. In the case of the females, a relationship was found to exist between body fat and degree of physical activity. Conclusions:The degree of physical activity shows itself to be a factor related to the health of adolescents, although taking on a different focus in each gender. Among the males, ...

Abstract: These observations suggest that preventive efforts focused on maintaining physical fitness and physical activity through puberty will have favorable health benefits in later years.
