Self-assessment and self-perception of the body in 18-year-old girls

INTRODUCTION

Studies focusing on self-perception of one's body usually cover subjects with eating disorders. There is a lack of similar studies.

AIM OF THE STUDY

Conducting survey research on self-assessment and self-perception of one's own body in girls.

MATERIAL AND METHODS

A survey was conducted in 1047 female students (average age: 18 years ±0.25) focusing on self-assessment and self-perception of their body mass, body parts, and eating habits. The study subjects were divided into groups of normal weight, obese, and underweight according to their BMI and BMI-SDS.

RESULTS

There were twice as many girls dissatisfied with their body weight in the underweight group and 10 times as many in the obese group. 8% of girls with normal body weight perceived their body as overweight. 70% of subjects with a normal body weight and ca. 25% of obese thought they were obese in the area of the abdomen, hips, buttocks, and thighs. Fear of gaining weight was characteristic most often for girls with abnormal body weight who confessed to eating disorders.

CONCLUSIONS

1. Most 18-year-old girls do not demonstrate any symptoms of distorted body self-perception; a vast majority of girls with normal body weight exaggerate the shapes of body parts, which causes them to undertake measures aiming to lose weight. Only a quarter of obese subjects perceive their individual body parts as obese, which might result in their lack of motivation to lose weight. 2. It is necessary to introduce healthy lifestyle educators in schools to prevent ED and obesity in adolescents.

Computer-tomographic characteristics of root length incisors and canines of the upper and lower jaws in boys and girls with different craniotypes and physiological bite

INTRODUCTION

In recent years, in world literature appeared research, which focuses on the study of relationships craniotypes with odonto-metric indicators, size, shape of the dental arches and occlusion. However, most of the experts focus on the study of individual features of the structure of the teeth-jaw system in people with different types of faces and aspects of sexual dimorphism and ethnic characteristics. Studies containing information about cranio-typological variability of the roots of teeth we did not encounter. The aim is to reveal features length of roots of incisors and canines of the upper and lower jaw, according to the CT scan in boys and girls of different craniotypes with physiological bite, residents Podilskiy region of Ukraine.

MATERIAL AND METHODS

The study involved young men with orthognathic bite and their cephalometric performance taken from database from Scientific and Research Center Vinnitsa National Medical University named after Pirogov. To make CT used dental cone beam CT scan - Veraviewepocs 3D, Morita. In the upper and lower incisors and canines were measured vestibular-oral and mesio-distal projection length of the root. The height (length) of the root was measured in the medial (or distal) norm, focusing on border basics crowns (root) and the apex of the tooth root. Established the following distribution craniotype: mesocephalic boys - 16, boys brachycephalic - 19, mesocephalic girls - 16, brachycephalic girls- 26. Statistical analysis of the results was performed using the statistical software package licensed "Statistica 6,0" using non-parametric estimation methods.

RESULTS

The peculiarities computed tomographic characteristics of root length incisors and canines of the upper and lower jaws in boys and girls Podilskiy region of Ukraine with different craniotypes and physiological bite have been set. In boys or girls mesocephals majority values of vestibular-oral and mesio-distal projection length of the teeth root, medial and lateral incisors in the upper and lower jaws significantly higher compared to studied similar gender brachycephals. Most values vestibular-oral and mesiodistal projection length of the teeth root, medial and lateral incisors in the upper and lower jaws in boys of total group and brachycephals significantly higher compared with girls of similar comparison groups. In boys mesocephals only value of vestibular-oral projection length of teeth root on the lower jaw was significantly higher compared with girls of the same craniotype.

CONCLUSIONS

In mesocephalic boys or girls majority values of vestibular-oral and mesio-distal length projection of the root teeth, medial and lateral incisors on the upper and lower jaws significantly higher compared to similar brachycephalic genders studied.
