The prevalence of dieting is alarmingly high amongst adolescents in South Africa. Dieting behaviour, influenced by the promotion of the thin ideal, poses one of the main risks for eating disorders, which have serious physical, psychological and social consequences, including death. Treatment of eating disorders is a costly, difficult and long-term process, therefore preventative measures have been advocated. One of the shortcomings of existing school-based primary intervention programmes has been the failure to bring about significant changes in body image, a key defining feature of eating disorders. This study evaluates the effectiveness of a modified version of Rosen's body image programme with adolescents, with the view to exploring the idea of adding a body image component to existing preventative programmes. The modified version of Rosen's programme proved to be effective in improving the body image of mid-adolescents. / Educational Studies / M. Ed.

Au cours des 30 dernières années, l’embonpoint et l’obésité infantile sont devenus de véritables défis pour la santé publique. Bien que l’obésité soit, à la base, un problème physiologique (i.e. balance calorique positive) une série de facteurs psychosociaux sont reliés à son développement. Dans cette thèse, nous avons étudié le rôle des facteurs périnataux et de la petite enfance dans le développement du surpoids, ainsi que la relation entre le surpoids et les troubles internalisés au cours de l’enfance et au début de l’adolescence. Nous avions trois objectifs généraux: 1) Modéliser le développement de l’indice de masse corporelle (IMC) ou du statut pondéral (le fait d’être en surpoids ou non) durant l’enfance, ainsi qu’estimer l’hétérogénéité dans la population au cours du temps (i.e. identification de trajectoires développementales de l’IMC). 2) Identifier les facteurs périnataux et de la petite enfance pouvant accroitre le risque qu’un enfant suive une trajectoire menant au surpoids adolescente. 3) Tester la possibilité que le surpoids durant l’enfance soit associé avec des problèmes de santé mentale internalisés à l’adolescence, et vérifier la possibilité qu’une telle association soit médiatisée par l’expérience de victimisation par les pairs et l’insatisfaction corporelle. Ce travail est mené dans une perspective de développement au cours de la vie (life span perspective), considérant l’accumulation des facteurs de risques au cours du temps ainsi que les facteurs qui se manifestent durant certaines périodes critiques de développement.1,2 Nous avons utilisé les données provenant de l’Étude Longitudinale du Développement des Enfants du Québec (ELDEQ), une cohorte de naissances de la province de Québec, Canada. L’échantillon initial était composé de 2120 familles avec un bébé de 5 mois nés au Québec en 1997. Ces familles ont été suivies annuellement ou à tous les deux ans jusqu’à ce que les enfants atteignent l’âge de 13 ans. En ce qui concerne le premier objectif de recherche, nous avons utilisé la méthode des trajectoires développementales fondée sur des groupes pour modéliser l’IMC en continu et en catégories (surpoids vs poids normal). Pour notre deuxième objectif, nous avons effectué des modèles de régression multinomiale afin d’identifier les facteurs périnataux et de la petite enfance associés aux différents groupes développementaux du statut pondéral. Les facteurs de risques putatifs ont été choisis parmi les facteurs identifiés dans la littérature et représentent l’environnement périnatal, les caractéristiques de l’enfant, ainsi que l’environnement familial. Ces facteurs ont été analysés longitudinalement dans la mesure du possible, et les facteurs pouvant servir de levier potentiel d’intervention, tels que l’usage de tabac chez la mère durant la grossesse, le sommeil de l’enfant ou le temps d’écoute de télévision, ont été sélectionnés pour l’analyse. Pour notre troisième objectif, nous avons examiné les associations longitudinales (de 6 à 12 ans) entre les scores-z d’IMC (selon la référence CDC 2000) et les problèmes internalisés avec les modèles d’équations structurales de type « cross-lagged ». Nous avons ensuite examiné comment la victimisation par les pairs et l’insatisfaction corporelle durant l’enfance peuvent médiatiser un lien potentiel entre le surpoids et les troubles internalisés au début de l’adolescence. Les contributions scientifiques de la présente thèse incluent l’identification de trajectoires distinctes du statut pondérale durant l’enfance (précoce, tardive, jamais en surpoids), ainsi que les facteurs de risques précoces et les profils de santé mentale pouvant différer selon la trajectoire d’un enfant. De plus, nous avons identifié des mécanismes importants qui expliquent une partie de l’association entre les trajectoires de surpoids et les troubles internalisés: la victimisation par les pairs et l’insatisfaction corporelle. / Child overweight and obesity has challenged the field of public health for several decades. While its direct underpinnings may be physiological, its development and outcome are intertwined with an array of psychosocial factors. This dissertation has sought to answer questions relating to the perinatal and early life risk factors associated with overweight development, as well as its potential psychological correlates during middle childhood and early adolescence. Specifically, this project had three research goals: 1) To model the developmental pattern of BMI or weight status throughout childhood and estimate population heterogeneity. 2) To identify the perinatal and early childhood risk factors that may increase the likelihood that a child follows a path leading to overweight by adolescence. 3) To examine whether being overweight in middle childhood is associated with internalizing mental health symptoms in early adolescence, and whether such an association is mediated by the experience of peer victimization and body dissatisfaction. This work takes a developmental life-course perspective in that it considers both the accumulation of risk factors over time as well as risk factors occurring during critical periods of development.1,2 We examined data drawn from the Quebec Longitudinal Study of Child Development (QLSCD), a population-based birth-cohort study in the province of Quebec, Canada. The initial sample consisted of 2120 families with a 5-month old baby born in Quebec in 1997. These families were monitored yearly or biennially until children were 13 years of age. For our first research goal, we modeled group-based developmental trajectories of child BMI and child weight status (overweight vs. not overweight). For our second goal, multinomial logistic regression analyses were conducted in order to identify the perinatal and early risk factors associated with the different developmental groups of weight status. Putative risk factors were chosen from the literature and represent the perinatal environment, child behavioral characteristics, as well as the family home environment. These were analyzed longitudinally when possible, and factors that could be targeted for intervention, such as maternal smoking during pregnancy, child sleep times or television viewing were selected for analysis. In order to complete our third research goal, we examined the longitudinal associations (from age 6 to 12) between BMI z-score (CDC 2000 reference) and internalizing and externalizing problems by way of cross-lag panel models in the Mplus program. Our results indicating sparse cross-lagged links, we then examined whether peer victimization and body dissatisfaction during childhood mediate the association between early overweight development and self-reported internalizing symptoms in early adolescence. Important scientific contributions stemming from this project include the identification of distinct weight status trajectories during childhood (i.e. early onset, late onset, never overweight) and the identification of perinatal and early life risk factors and mental health outcomes that may differ depending on a child’s developmental trajectory. Additionally, we identified two important mechanisms of the association between overweight and internalizing problems: peer victimization and low body satisfaction.

This diploma thesis explores the phenomenon of formation and development of alcohol dependence. In the first series focuses on the historical description, which demonstrates considerable anchored in the life of our ancestors already. It also defines the concept of addiction, its causes and consequences, whether psychological, medical or social. Its objective is to describe the possibilities of social work in this phenomenon. defines therefore primarily targets and understanding of social work and consequently specifics of client alcoholism. An important element is the role of the social worker in the client's motivation to change, which uses Nešpor's model of spontaneous changes in motivation. Then, on the basis of available social services selects several most suitable, which can help to improve the client's situation. Has an essential role in this issue also primary prevention, ie it discusses the methodology, target groups, focusing on adolescents and the focus is on the firm role of the family. Finally contains some official documents on primary prevention, which are discussed current issues of primary prevention practice and subsequent survey, mapping aspect of social workers on the incidence risk of alcohol dependence among adolescents attending social facilities.

Fatores associados com falhas na cobertura da vacinação contra o sarampo na cidade de São Paulo foram estudados por meio de entrevistas com pais ou responsáveis por 122 crianças de até cinco anos. Observou-se que a população conhece a doença e identifica a vacina com a idéia de proteção, mas não cumpre o calendário de vacinação e atrasa as doses da vacina contra o sarampo. Idade, região de origem ou de residência, status familiar ou nível educacional não mostraram associação com o cumprimento do calendário obrigatório (uma dose da vacina contra o sarampo deve ser aplicada dos 9 aos 11 meses e a segunda, aos 15 meses). A televisão é o meio de comunicação que mais informa os entrevistados sobre as Campanhas Nacionais de Multivacinação e o cartão de vacinação foi identificado como uma das vias de comunicação utilizadas para informar sobre a vacinação fora das Campanhas, na rotina. No entanto, nenhum meio de comunicação identificado no estudo pôde, significativamente, promover a mudança de comportamento da indife rença para o compromisso com o cumprimento do calendário, ou seja, adesão. A única variável significativamente relacionada com o atraso na vacinação, de até 20 dias, foi o sentimento de dó de aplicar injeções nas crianças (p = 0,08). Crianças brasileiras têm de visitar o posto de saúde para receber, até cinco anos de idade, 19 vacinas, 12 até o primeiro ano. O estudo deixa claro que não há adesão ao calendário proposto para vacinação contra o sarampo, apesar de ser esta a proposição das Campanhas Nacionais de Multivacinação e da vacinação de rotina / Risk factors associated with failure to receive measles vaccine were studied in eight districts of São Paulo city, Brazil. Parents or carers of 122 children were interviewed about their perception and understanding about the disease anda about measles vaccination, a kind of knowledge that can be acquired through vaccination communication campaigns or from personal communication (from the doctors, nurses of the health care center or friends). Population description factors were also identified. Results analysis shows that neither age, region of origin or residence, marital status nor educational level were related to taking or not taking measles vaccines adequately. Most of the people remembered about having being informed about the last annual vaccination campaign by television, but no communication channel was significantly associated with vaccination status. Answers to questions about knowing the disease or not or knowing the vaccine or not, when analysed alone, did not show any association with taking measles vaccines at the time indicated by health agencies. However, the results showed that when parents felt pity for their children receiving shots, they delayed the vaccination for at least 20 days. Since families visit the health center at least seven times before children complete five years of age and since most of the children does not take the measles vaccine in the exactly recommended day, but delay or anticipate the shots, it is clear that there is no compliance to the recommended government\'s measles vaccination schedule (first dose at 9 and second at 15 months of age), although this is the message that annual communication campaigns and interpersonal communication try to pass

This is a qualitative study that was intended to analyse the role of South African Police Services (SAPS) railway policing in crime prevention in South Africa (SA). Commuters are exposed to various criminal activities in the railway environment. The Metro Rail trains are the most affordable trains and for that reason, the majority of commuters use these trains to travel to and from their workplaces. This study focused on the large stations in the Gauteng province, South Africa, as there is a high influx of people coming from various provinces for job opportunities. Alexander (2019:np) states that Gauteng is the smallest province, but has the largest population and economy. The non-random sampling procedure was used to select participants. Data was collected by means of perusing the existing literature, SAPS information notes, official documents and articles. Interviews were conducted with South African Police Service Rapid Rail Unit (SAPSRRPU) members. Each unit was represented by a maximum of eight members. The information obtained from the participants was analysed by using the Atlas-ti software. This is a computer program used to analyse data in qualitative research. / Iyi ndi ngudo ya ndeme i itelwaho u saukanya mushumo wa yunithi ya vhupholisa ha raliwei ya Tshumelo ya Tshipholisa ya Afrika Tshipembe (SAPS) kha u thivhela vhugevhenga Afrika Tshipembe (SA).

Abstract in English, Xhosa and Afrikaans / The victimization of women and children represents one of the public health problems deserving urgent attention in Ethiopia, making the prevention of rape in all its forms a matter of vital importance. The purpose of the study was mainly to describe the extent of rape prevention interventions in Addis Ababa and examine efforts to assist rape survivors based on the perceptions of professionals working for organizations operating in this context. The study had a further purpose of identifying difficulties faced by government institutions and making suitable recommendations for the improvement of rape prevention interventions and programs in the future. A qualitative descriptive research approach was adopted mainly involving in-depth interviews for primary data collection. The study involved 14 research participants purposively selected from five government institutions. The study findings indicated Gandhi Memorial Hospital to be the only institution in Ethiopia implementing an integrated rape prevention intervention. Efforts were directed largely at secondary prevention, with little attention being paid to primary prevention. Recommendations included tackling the multiple factors influencing rape at different levels of the social-ecological model simultaneously through the implementation, strengthening, and intensification of well-designed, comprehensive rape prevention interventions and programs. / Ukuxhatshazwa kwabafazi nabantwana e-Ethiopia kufana nenye yeengxaki zempilo kwaye kudinga ukuthathelwa ingqalelo ngokungxamisekileyo. Oku kwenza ukuba ukuthintela ukudlwengulwa ngazo zonke iindlela kube ngumbandela obaluleke kakhulu. Injongo yesi sifundo ibikukucacisa iindlela zokuthintela ukudlwengulwa eAddis Ababa, nokuvavanya imizamo yokunceda abo bakhe badlwengulwa, ngokokubona kwabo basebenzela amaqumrhu aququzelela lo msebenzi. Enye injongo yesi sifundo ibikukuchonga ubunzima obufunyanwa ngamaziko aseburhulumenteni ajongene neli candelo ukuze kunikwe iingcebiso zokuphucula amacebo neenkqubo zokuthintela ukudlwengulwa. Kuqhutywe uhlobo lophando lomgangatho nolucacisayo, apho kuqokelelwe iinkcukacha zolwazi ngokwenza udliwano ndlebe olunzulu. Kusetyenzwe nabathathi nxaxheba abali-14 abakhethwe ngobuchule kumaziko aseburhulumenteni ama-5. Okufunyaniswe sesi sifundo kubonakalise ukuba isibhedlele esiyiGandhi Memorial siso sodwa esinenkqubo elungelelaniswe kakuhle yokuthintela ukudlwengulwa. Imigudu yokhukhusela ijoliswe ekuncedeni kwiziqhamo zodlwengulo nasekufundiseni ngodlwengulo (secondary prevention) hayi kudlwengulo ngqo (primary prevention). Amacebiso esifundo aquka ukulwa neemeko eziphembelela udlwengulo olwenzeka kumazinga ahlukeneyo oluntu, ngaxeshanye nokuqinisa ukusetyenziswa kweenkqubo eziqulunqwe kakuhle zokuthintela udlwengulo. / Die viktimisering van vroue en kinders is een van talle kwessies in die openbare gesondheid van Ethiopië wat dringend aandag vereis, aangesien die voorkoming van verkragting in enige vorm van die allergrootste belang is. Die doel van hierdie studie was om die omvang te bepaal van intervensies om verkragting in Addis Abeba te voorkom, en om die hulp wat aan verkragtingslagoffers verleen word, te ondersoek op grond van die belewenisse van beroepslui wat in hierdie verband vir organisasies werk. Hierdie studie het dit verder ten doel gehad om die probleme aan te toon waarmee staatsinstellings in hierdie opsig te kampe het, en om beter intervensies en programme vir die voorkoming van verkragting aan te beveel. ʼn Kwalitatiewe en deskriptiewe navorsingsbenadering is gevolg. Dit het omvattende onderhoude behels waartydens primêre data versamel is. Altesame 14 deelnemers by vyf staatsinstellings is vir hierdie doel gekies. Volgens die bevindings is die Gandhi Gedenkhospitaal die enigste instelling in Ethiopië wat ʼn geïntegreerde program vir die voorkoming van verkragting ingestel het. Sekondêre voorkoming geniet voorrang, terwyl primêre voorkoming min aandag geniet. Daar word aanbeveel dat tegelykertyd werk gemaak word van die veelvuldige faktore wat verkragting op verskillende vlakke van die sosiaal-ekologiese model beïnvloed. Dit moet gedoen word deur deeglik ontwerpte, omvattende intervensies en programme om verkragting te voorkom in werking te stel, uit te bou en te verskerp. / Sociology / M.A. (Sociology)
