The aim of the present study was to assess the adolescents’ weight status and weight status perception and also to examine the influence of weight status misperception on weight related behaviors. The survey was conducted in 2014 in population consisting of 125 adolescents aged 15 years living in Sopot, in northern Poland. An anonymous questionnaire contained questions concerning body mass and height and questions on weight status perception and previous weight loss attempts. The study found a high prevalence of excessive body mass among adolescents. Overestimation of weight status had stronger influence on the number of weight loss attempts than underestimation and accurate perception. The study also revealed significant differences between boys and girls in accuracy of weight status perception that could be caused by gender-based stereotypes related to body shape.

Celem pracy była ocena zjawiska stosowania diet odchudzających wśród licealistek oraz jego przyczyny i skutki. Badaniem objęto grupę 100 dziewcząt w wieku 16–19 lat uczęszczających do liceum ogólnokształcącego w Kartuzach (województwo pomorskie). Posłużono się anonimową ankietą oceniającą rodzaj diet odchudzających używanych przez nastolatki oraz zachowań związanych z ich stosowaniem. Na podstawie pomiaru wysokości i masy ciała obliczono wskaźnik masy ciała BMI (Body Mass Index). W przeprowadzonym badaniu wykazano, że ponad połowa (56%) licealistek stosowała diety odchudzające. Aż 30% dziewcząt zgłaszało działania niepożądane obserwowane w trakcie diety, takie jak: pogorszenie wyglądu skóry i paznokci, wypadanie włosów, omdlenia, niedokrwistość oraz brak miesiączki. Odnotowano, że 70% respondentek było niezadowolonych ze swojego wyglądu i chciałoby schudnąć. Prawie wszystkie nastolatki stosowały dietę bez pomocy specjalisty dietetyka. Zaobserwowane zachowania żywieniowe mogą przyczyniać się do rozwoju chorób dietocywilizacyjnych, jednak przede wszystkim zaburzeń odżywiania. Istotne jest wprowadzenie wczesnej edukacji zdrowotnej nastolatków opartej na atrakcyjnych metodach edukacyjnych, m.in. wskazujących wiarygodne źródła informacji na temat zdrowego odżywiania się.

Was used an anonymous questionnaire assessing the type of weight loss diets used by teenagers and behaviors associated with their use. On the basis of measuring the height and weight calculated BMI (Body Mass Index). Our study has shown that more than half (56%) of high school students applied slimming diets. As many as 30% of girls reported adverse reactions observed during treatment with supplements such as deterioration of the appearance of the skin and nails, hair loss, fainting, anemia and amenorrhea. It was noted that 70% of respondents were dissatisfied with their appearance and would like to lose weight. Almost all teenagers use the diet without the help of a professional dietician.

The present work discusses results concerning sound perception obtained in a pitch memorization experiment for blind and visually impaired subjects (children and teenagers). Listeners were divided into two age groups: 7–13 year olds and 14–18 year olds. The study tested 20 individuals (8 congenitally blind and 12 visually impaired) and 20 sighted persons comprising reference groups. The duration of the experiments was as short as possible due to the fact that our listeners were children. To date, no study has described results of such experiment for blind/visually handicapped children and teenagers. In the pitch memory experiment blind teenagers outperformed blind children and both age groups of visually impaired subjects in two out of three tested cases. These results may have implications for the development of auditory training in orientation and mobility of young visually handicapped people.
