A survey of primary prevention services for adolescents' reproductive health needsMataboge, Mamakwa Letlhokwa Sanah 25 August 2009 (has links)
The study comprehensively analysed the impact of primary prevention services for reproductive health in the environment within which the adolescents grow towards life skills ecquisition and positive behavior patterning. The availability, accessibility and the effectiveness of adolescents' accompaniment in Soshanguve Township by certain caregivers were assessed. Unstructured observations, review of documents, questionnaire and semi-structured interviews were used for data collection.
The results revealed the least support by parents and churches to accompany the adolescents and the inaccessibility of specialised center to the disadvantaged. The continued lack of knowledge and life-skills perpetuated the onset of reproductive problems. The lack of programmes to equip care providers on how to improve communication during care provision was a major setback. There is a great need for the erection of special care centers for adolescents. / Health Studies / M.A. (Nursing Science)

Adherence to antiretroviral therapy by adolescents in Maseru : influencing factors and social work supportBoopa, Mafusi Claurana 02 1900 (has links)
Adherence to long-term medications has remained a problem among adolescents worldwide. Antiretroviral therapy adherence is a wide-reaching challenge among HIV positive adolescents. The aim of this study is to explore and describe poor ART adherence among HIV positive adolescents in Maseru: influential factors and the need of social work support.
Qualitative approach was used, following an explorative, descriptive and contextual research design. The research was conducted at BCMCOE Lesotho. Data was collected by using semi-structured in-depth interviews and purposive sampling was applied to select a sample of adolescents who are HIV positive and who have poor adherence to ART. Data was analysed according to the framework provided by Tesch (in Creswell 2003). Guba’s model (in Krefting 1991) was employed for data verification. Conclusions were drawn and recommendations were made about factors influencing adherence of adolescents to ART and support needed from social workers. / Social Work / M.A.(S.S.)

Modelos matemáticos para estimativa da gordura corporal de adolescentes utilizando dobras cutâneas, a partir da absorciometria de raios-X de dupla energia / Mathematical models for the estimation of the fat mass of adolescents based on skinfold thickness, using dual-energy X-rays absorptiometryRipka, Wagner Luis 07 April 2017 (has links)
Introdução: Estudos têm encontrado uma transição da obesidade da população adulta para crianças e adolescentes, que por sua vez, pode acarretar manifestações clínicas, como: doenças coronarianas, diabetes tipo 2, e complicações psicossociais cada vez mais precocemente. Contudo, métodos para avaliação da composição corporal para essa faixa etária, principalmente envolvendo técnicas de baixo custo como as medidas de dobras cutâneas (DC) apresentam imprecisões em estudos brasileiros. Fator o qual pode levar a uma interpretação equivocada da composição corporal dos avaliados. Objetivo: desenvolver novos modelos matemáticos utilizando medidas de DC, tendo como referência a absorciometria de raios-X de dupla energia (DXA), para estimativa de massa de gordura (G) em adolescentes. Métodos: Trata-se de um estudo exploratório descritivo onde foram avaliados 416 adolescentes do gênero masculino de 12 a 17 anos, sendo 42 destinados para compor a amostra de validação da pesquisa. Foram coletadas medidas de massa corporal total, estatura, circunferência da cintura e quadril, nove pontos anatômicos baseados em DC: bíceps, tríceps, subescapular, peitoral, axilar média, abdominal, supra-ilíaca, coxa e panturrilha, além da G e densidade mineral óssea (DMO) aferida com a tecnologia de DXA. Para o desenvolvimento das equações foi utilizado um modelo de regressão linear múltipla através do método de mínimos quadrados ordinários (OLS). Resultados: O grupo apresentou índice de massa corporal (IMC) médio de 21,25±4,12kg/m² e %G = 20,57±5,80%. A partir do %G, a prevalência de excesso de gordura foi verificada em 38,3% dos adolescentes. O impacto da gordura na DMO dos adolescentes indicou uma associação na ordem de r = -0,358; p<0,005, sendo verificada redução de até 14% da DMO para a região da coluna em adolescentes com obesidade em comparação aos eutróficos. O desenvolvimento de novos modelos matemáticos que atendessem critérios de alto coeficiente de determinação (R²), baixo erro padrão de estimativa (EPE), controle de colinearidade, normalidades dos resíduos, homoscedasticidade e praticidade, possibilitaram a apresentação de três opções com R² = 0,932 e EPE 1,79; R² = 0,912 e EPE = 1,78; R² = 0,850 e EPE = 1,87, respectivamente. Em todas as opções, as variáveis idade e estatura foram empregadas, bem como as DC de tríceps e subescapular. Conclusão: Os resultados obtidos evidenciam a possibilidade de desenvolvimento de novos modelos matemáticos para a avaliação da gordura corporal em adolescentes com resultados superiores aos modelos existentes na literatura. / Introduction: Studies have found a transition from obesity of the adult population to children and adolescents, which in turn, can lead to clinical manifestations, such as: coronary diseases, type 2 diabetes, and psychosocial complications increasingly early. However, methods for evaluating nutritional status for this age group, mainly involving low cost techniques such as skinfold thickness measurements (ST), are imprecise in Brazilian studies. Factor which can lead to a mistaken interpretation of the body composition of the evaluated ones. Objective: To develop new mathematical models, based on DC measurements, based on dual energy X-rays absorptiometry (DXA), to estimate fat mass (G) in adolescents. Methods: This was an exploratory descriptive study in which 416 male adolescents aged 12 to 17 years were evaluated, 42 of whom were separated to compose the study validation sample. Measurements of total body mass, stature, waist and hip circumference were obtained, nine anatomical points based on ST: biceps, triceps, subscapular, pectoral, mid axillary, abdominal, suprailiac, thigh and calf muscles, as well as G and bone mineral density (BMD) measured with DXA technology. For the development of the equations, a multiple linear regression model was used by the ordinary least square (OLS) method. Results: The group had a mean body mass index (BMI) of 21.25± 4.12 kg / m² and %G = 20.57 ± 5.80%. From %G, the prevalence of excess fat was verified in 38.3% of adolescents. The impact of fat on adolescent BMD indicated an association in the order of r = -0.358; P <0.005, with BMD reduction up to 14% for the spine region in adolescents with obesity compared to eutrophic. The development of new mathematical models that meet criteria of high coefficient of determination (R²), low standard error of estimation (SEE), control of colinearity, residue normalities, homoscedasticity and practicality, allowed the presentation of three options with R² = 0.932 and SEE 1.79; R² = 0.912 and SEE = 1.78; R² = 0.850 and SEE = 1.87, respectively. In all the options, the variables age and height were employed, as well as triceps and subscapular ST. Conclusion: The results obtained evidenced the possibility of developing new mathematical models for the evaluation of body fat in adolescents with results superior to the existing models in the literature.

Factors contributing to high adolescent pregnancy rate in Kinondoni municipality, Dar-es-Salaam, TanzaniaPhilemon, Margareth Nkuba 30 November 2007 (has links)
This study seeks to describe the factors contributing to high adolescent pregnancy rate in Kinondoni Municipality, Dar-es-Salaam. Through the study we get to know the social economic characteristics of adolescents, the adolescents' general knowledge of reproductive health issues and the source of this knowledge.
The major discoveries made from this study are that the educational status and knowledge of reproductive health of these adolescents is low, some are already dropouts from school, and others were deprived of the chance to continue with secondary education. They have nothing tangible to do because of their low education and coupled with their low economic status, they are at risk of being involved in sexual activities at an early age, ending in pregnancies. In addition, their parents' educational and economic status was also found to be low.
It is important then, parents, teachers and the community in general to arrest the rate of adolescent pregnancies. / HEALTH STUDIES / MA (HEALTH STUDIES)
