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.

Tarantobelus arachnicida (Nematoda: Rhabditida) invasion of exotic spiders in Poland

Nematodes of the Brevibuccidae family were stated among spiders of the Theraphosidae family (the South American species), which were bred in Poland. The first sign of infection was anorexia which led to gradually increasing lethargy progressed to a huddled posture. Additionally, a white discharge with nematodes between mouth and chelicerae was noted. All of the derived nematodes were morphologically identified and determined to the species Tarantobelus arachnicida. A molecular analysis covered amplification and sequencing of small subunit ribosomal RNA (18S rRNA). A post mortem examination demonstrated the presence of nematodes not only near the chelicerae, but also inside the intestine, hence the source of infection might be insects used as a food. The research showed that such kind of infection is an important disease, which poses a serious risk to the breeding spiders. To date there is no effective treatment, however, we demonstrated that usage of the Lugol's solution seems to be promising.

Trends of underweight and obesity prevalence among adolescent girls in the selected population of the Silesian Agglomeration.

OBJECTIVE OF THE STUDY: 1. Determination of the state of nutrition in the examined population of 18-year-old girls. 2. Retrospective determination of the state of nutrition of the same girls when they were 14 years old. 3. The answer to the question whether the examined group exhibits the tendency to consolidate abnormalities in terms of the body weight over time. MATERIAL AND METHODS: 1047 female students of secondary schools, aged 18, were subjected to anthropometric measurements (body weight, height, BMI, BMI-SDS) and took part in a survey questionnaire devoted to their eating habits. The measurement results of the same girls aged 14 were obtained retrospectively. RESULTS: When the subjects were 14 years old, 79.7% of them had a normal body weight, 14.9% were obese, and 5.4% were underweight. At the age of 18, 76.6% of the subjects had a normal body weight, 17.2% were obese, and 6.2% were underweight. 4.7% of the girls with a normal weight aged 14 reduced their body weight, and 9.2% became obese at 18 the age of 18. None of the underweight subjects demonstrated obesity at the age of 18, and 45.6% maintained their body weight below the normal limits. 66% of the girls who were obese at the age of 14 maintained their obesity at the age of 18. CONCLUSIONS: 1. Most girls in the examined population at 14 and 18 years of age demonstrate a normal nutrition state. Obesity was observed in 15% of the examined females at the age of 14 and in 17% at the age of 18, whereas 5% of girls aged 14 and 6% of girls aged 18 are underweight. 2. From early to late adolescence a tendency to persistent abnormalities of the nutritional status is observed in girls. 3. Obesity in girls aged 14 is a predictor for obesity at the age of 18 and perhaps in the adult life.
