The purpose of this study is to investigate the difference between athletes and non-athletes by addressing prevalence of disordered eating and eating disorders, the risk factors associated with the disease(s), and health concerns for those suffering with disordered eating.

Thesis (PhD (Sport Science))--University of Stellenbosch, 2006. / The continued integration of our global society has caused a shift in human social interaction and redefined the contexts of adolescents’ lives. Adolescents are inundated with a variety of choices at a stage of their lives where they are trying to create their own identity. This critical period of development is highlighted by an increased desire to experiment with adult life. Thus is experimentation not uncommon. The study examines the prevalence of a range of health risk behaviours amongst adolescent girls. It focuses on the identification of behaviours such as violence, smoking, alcohol and drug use and abuse, sexual behaviours, dietary behaviours and physical inactivity that place adolescents at increased risk for premature morbidity and mortality. An intervention programme was launched at the schools concerned in an effort to address these behaviour patterns and to inform learners regarding the dangers of these health risk factors. The sample population was selected from three previously disadvantaged high schools in the Worcester region. Due to restrictive circumstances at the schools, the sample could not be randomly selected and therefore the study is based on a quasi-experimental research approach. A sample of 1805 adolescent girls in Grades 8 to 10 completed a questionnaire, which assessed a range of health risk behaviours. This questionnaire was based on the Youth Risk Behaviour Survey (YRBS) and completed by all the respondents during the pre-test. A control and experimental group was selected from the Grades concerned, at the different schools. The experimental group was subjected to a six-months long intervention programme. At the end of the intervention programme a post-test was conducted on both the control and experimental groups. Four months after the post-test the respondents were subjected to the same test, which is now known as the follow-up test. The girls who dropped out of the study as it progressed are referred to as the drop-out group. Information regarding the socio-economic background of the girls, as well as permission to take part in the study, was obtained from the parents by means of a questionnaire. A self-designed questionnaire was used to obtain information regarding the state and status of Physical Education (PE) and movement programmes within Life Orientation at the schools. Teachers who were responsible for Grades 8, 9 and 10, completed the questionnaire. To keep track of body size and growth, mass and length were determined and body mass index (BMI) was calculated. Blood pressure was measured to determine to what extend these girls suffer from hypertension. Skinfold measures were taken to determine the fat percentage. The 20m shuttle run (Bleep test) was used to indirectly determine the physical activity levels of the respondents. The main results are discussed next. The results indicate that more respondents in the post-test (64%) reported that learners carry weapons on school grounds than in the pre-test. According to the results 64% of the respondents indicated in the post-test that learners carry weapons on school grounds compared to 29% of the respondents in the follow-up test (p<0.01). The pre-tests results indicate that 11% of the respondents smoke cigarettes in comparison to 14% in the post-test (p<0.01). Approximately 9% of the respondents in the pre-test indicated that they drank at least one alcoholic drink in the week before the study was undertaken in comparison to the 22% of the post-test (p<0.01). Regarding the smoking of dagga 2% of the respondents indicated in the pre-test that they smoked dagga whereas 9% in the post-test indicated that they did. More sexual active respondents during the follow-up test (57%) indicated that they used condoms during their last sexual experience than in the post-test (46%). The results of the pre-test indicate that approximately 49% of the respondents did something to loose weight or to prevent weight-gain in comparison to the 25% of the post-test and the 31% of the follow-up test. According the results, 35% of the respondents purported to have PE at their school in comparison to 30% during the post-test and 54% during the follow-up test. Although there were some exceptions, in most cases a tendency existed that indicated an increase in the variables measured between the pre-test and post-test. In most cases the results remained constant between the post-test and the follow-up test. This study can therefore be a starting point for further research into the process to combat health risk behaviours amongst adolescent girls. This can be done with educational programmes in cooperation with several role-players in the community.

D.Litt. et Phil. / Although PMS has been described almost since the beginning of the written history of medicine, it is still not completely understood. There are many theories about its causation and treatment, and a proliferation of symptoms are ascribed to it. The prevalence of PMS in relation to the total population is still unknown, because premenstrual symptoms or a combination of these range from almost 25% to 100% amongst women. Furthermore, different criteria for the assessment of the prevalence of PMS are used by different researchers. Researchers are in agreement, however, that no single definition for PMS exists. Some women experience mainly psychological symptoms, while others present predominantly physical symptoms. Very little is known of the prognosis of the natural history of PMS. The precise causes of menstrually-related distress is not known, although much has been written about the role that nutrition plays in PMS. A direct relationship has not been identified between individual levels of, and changes in, oestrogen and progesterone alone, and the reported psychological, behavioural and physical changes associated with the cycle. Certain observable behaviours are associated with the premenstrual phase of the cycle, such as aggressive and illness behaviour. An important aspect is the link between premenstrual changes and psychopathology, especially mood disorders. Many researchers report a positive association between premenstrual changes and mood disorders, especially depressive disorders. Women suffering from depressive disorders are reported to frequently experience a premenstrual exacerbation of symptoms and a deterioration in functioning. Most studies have found that women report both psychological and somatic symptoms. The psychological symptoms are, owever, more commonly reported and have also been found to be more distressing for women. In respect of aetiological theories, the literature shows a major subdivision between the biological causes and the psychological basis. Potential causes, according to a biological approach include abnormalities in gonadal steroids, excessive fluid retention, hypoglycemia, abnormalities in prostaglandin metabolism, allergy to endogenous hormones and endogenous opiate withdrawal. Research results in each of these areas are conflicting and conclusions reached are speculative. Most psychological aetiologies originate from the psychoanalytical school and include a rejection or resentment of the feminine role, as well as a repressed wish for a child. At present, the psychoanalytical theories have not been supported by controlled studies and, therefore, still remain speculative. The uncertainty of the causes of PMS is reflected in the numerous treatments proposed in the literature. A review of the literature shows that treatment for PMS is generally given indiscriminately for a divergent group of symptoms, without regard for the fact that growing evidence suggests that the Syndrome is made up of a variety of distinct, but related, symptoms. A girl's first menstruation is a developmental milestone with psychological and physiological concomitants. Adolescents of both sexes tend to view menstruation negatively. Many adolescents associate menstruation with dysmenorrhea. Studies have shown that up to 91% of girls report dysmenorrhea, and it is also the leading cause of recurrent short-term school absenteeism among adolescent girls. Dysmenorrhea cannot be ignored, as it leads to a loss in self-esteem, with all the accompanying problems. If an adolescent does not get help with her PMS symptoms, she may be negatively affected. The purpose of the present study was to cross-culturally investigate the psychological concomitants of the premenstrual symptomatology in adolescent girls. Four hypotheses were tested: In an analysis of symptoms associated with PMS, a single factor reflecting will emerge to account for a significant percentage of the variance observed; Dysmenorrhic adolescents will experience a greater number of negative premenstrual symptoms than non-dysmenorrhic adolescents; Adolescents experiencing a number of negative premenstrual symptoms will report lower self-esteem; Adolescents of different cultural groups will report PMS symptoms that are IV commensurate with their culturally-based health beliefs. In order to test these hypotheses, one hundred and twenty five adolescent girls of all race groups, between 13 and 18 years of age, who were not taking any contraceptive, participated in the study. The Premenstrual Assessment Form (PAF) and the Index of Self-Esteem (ISE) were used. Physical and emotional discomfort emerged as two clear interpretable factors. It would appear that for this sample, PMS is not a unitary phenomenon, but consists of dual factors which are depended on cultural expectations. By observing dysmenorrhic and nondysmenorrhic adolescent girls, it was found that dysmenorrhic girls manifested a significantly higher degree of low mood and loss of pleasure, "endogenous" depressive features, lability, "atypical" depressive features, hysteroid features, hostility and anger, social withdrawal, anxiety, impulsivity, organic mental features, general physical discomfort, water retention, autonomic physical changes, fatigue, impaired social functioning, impaired miscellaneous mood and behaviour changes and miscellaneous physical changes than non-dysmenorrhic girls. Non-dysmenorrhic girls showed a significantly higher degree of well-being when compared with dysmenorrhic girls. Thus, the present study supported the findings of previous research which suggested that dysmenorrhic girls will experience more negative premenstrual symptoms than nondysmenorrhic girls. In respect of self-esteem, girls reporting a number of negative premenstrual symptoms were found to have a lower self-esteem than those reporting fewer negative premenstrual symptoms. In respect of culture, it was found that culture seemed to play a role in the girls' perceived experiences of PMS. The present study indicates that adolescent girls do experience many negative symptoms and, if these are not adequately dealt with, they may adversely affect them in adulthood.

This quantitative, explorative and descriptive survey attempted to determine factors that influence the adolescent pregnancy rate in the Greater Giyani Municipality. Data were gathered from adolescent girls attending four selected high schools. Non-probability convenient sample of 147 respondents was used with 100% return rate. Data was collected using a questionnaire which had a reliability of 0.65. Data were analysed using the SAS/Basic computer program, version 9.2. Findings indicated that 56.34% of respondents reported key psychosocial variables such as peer pressure and 58.90% of them changed values as contributory to high pregnancy rates. .Health services were reported as not freely available and relationships with nurses significantly cited as poor by 72.41% respondents with regard to maintenance of confidentiality. Recommendations were made to improve school health services, reproductive education and future research / Health Studies / M.A. (Health Studies)

Indiana University-Purdue University Indianapolis (IUPUI) / African American adolescents have inadequate self-management behaviors, particularly during middle adolescence (14-16 years of age). Inaccurate beliefs, degree of asthma impairment (well controlled or not well controlled), and gender could influence asthma self-management (symptom management, medication management, and environmental control). The researcher used the illness representations concept from the common sense self-regulation model as the framework for this study. The descriptive correlational study explored (1) differences in illness representations (cognitive and emotional) and self-management behaviors by gender, asthma impairment, and gender by asthma impairment of African American adolescents with asthma; and (2) relationships between illness representations and asthma self-management behaviors, gender, and asthma impairment in 133 African American adolescents with asthma. Data were collected using the Asthma Control Test, the Illness Perceptions Questionnaire-Revised, and the Asthma Self-Care Practice Instrument. Data were analyzed using ANOVA, MANOVA, Pearson correlations, and multiple regressions. Findings indicated that females whose asthma was not well controlled had more beliefs about the chronicity of their asthma than those who were well controlled. However, there were no differences in such beliefs among males whose asthma was not well controlled from those who were well controlled. Well controlled adolescents differed from not well controlled adolescents for cognitive representations of cyclic timeline, treatment control, psychological attributes, and consequences as well as for emotional representations. There were no significant differences in the means of the self-management behaviors by gender, by asthma impairment, or by gender by asthma impairment. A significant bivariate relationship was found between representations of identity, consequences, treatment control, and symptom management. In the multiple regression model, representations of treatment control and consequences contributed to variances in symptom management; however, no other representations, gender, or asthma impairment variables were statistically significant. The representations, gender, and asthma impairment variables did not contribute to variances in medication management or environmental control. Limited studies have been conducted with African American adolescents with asthma; therefore, the findings will contribute information to the literature on their illness representations and self-management behaviors. The findings also contribute to the literature information based on adolescents' genders and levels of asthma impairment.
