Sexual Behaviour and Sexually Transmitted Infections Among Urban Ugandan Youth – Perceptions, Attitudes and Management

Råssjö, Eva-Britta January 2006 (has links)
<p>The aims of this thesis were to expand the knowledge about sexual and reproductive health among urban Ugandan youths, living in a slum, and to evaluate the national flow-chart for management of the abnormal vaginal discharge (AVD) syndrome in adolescent girls. Data collection included individual interviews, focus-group discussions and clinical investigations with tests for chlamydia trachomatis (CT), neisseria gonorrhoea (NG), trichomonas vaginalis (TV), syphilis, and HIV infection. Poverty, peer pressure and gender power imbalance were obstacles to safe sexual practices: to abstain from sex, be faithful or to use condoms. Prevalence among the 199 female and 107 male adolescents for CT, NG, TV, syphilis and HIV was 4.5%, 9.0%, 8.0%, 4.0% and 15.2% for females and 4.7%, 5.7%, 0%, 2.8% and 5.8% for males. The national AVD flow-chart had a sensitivity of 61%, a specificity of 38.5% and a positive predictive value (PPV) of 11.6%. A flow-chart using risk factors, rather than symptoms, implicated a sensitivity/specificity and PPV of 82.6%/47% and 17.3% respectively. Socially disadvantaged females had a high risk to be HIV infected and HIV infection was associated to other STIs. Females were more likely than males to have any of the infections studied. Voluntary counselling and testing (VCT) for HIV was considered as helpful in preventing the spread of HIV. Obstacles for testing were: lack of time and money, fear of stigmatisation and fear that the knowledge of HIV positive status could shorten someone's life. An alternative flow-chart for management of AVD among adolescent girls should be evaluated. Girl's opportunities for education and income generating work should be a priority. VCT services for young people should be made accessible in terms of cost, time and quality of counselling.</p>

Whose Knowledge Counts? : A Study of Providers and Users of Antenatal Care in Rural Zimbabwe

Mathole, Thubelihle January 2005 (has links)
<p>This thesis presents perspectives and experiences of different stakeholders and their ways of reasoning around pregnancy and pregnancy care. Data were generated from individual interviews with 25 health care providers, 18 women and 6 traditional birth attendants (TBAs) as well as 11 focus groups discussions with women, men and TBAs. </p><p>The challenges experienced by health care providers in their provision of antenatal care, while attempting to change antenatal care through routines proven to have medical value, are highlighted. Changing some long established routines, such as weighing and timing of visits, proved difficult mostly because of resistance from the users of care, whose reasoning and rationale for using care did not correspond with the professional perspectives of care. </p><p>Women also combined biomedical and traditional care. The women used the clinic to receive professional care and assurance that the pregnancy was progressing well and used TBAs, who are believed to have supernatural powers, for cultural forms of assurance and protection. The health care staff did not appreciate these aspects and discouraged women using TBAs. Midwives had problems to change routines of care because of their stressful working situations and the expectations of the women.</p><p>In addition, they described the paradoxes in providing antenatal care in the context of HIV and AIDS. The caregivers were aware of the magnitude of HIV and AIDS and yet did not have any information on the HIV status of the women they cared for. This also caused fear for occupational transmission. HIV/AIDS is highly stigmatised in this area and women used various strategies to avoid testing.</p><p>The study emphasised the need to broaden the conceptualisation and practice of evidence-based care to incorporate different types of evidence and include realities, knowledge and perspectives of not only the beneficiaries but also those implementing change as well as local knowledge. The necessity of reorganising the health care systems to accommodate the new challenges of the HIV/AIDS epidemic is also emphasised.</p>

HIV and Infant Feeding : Operational Challenges of Achieving Safe Infant Feeding Practices

Doherty, Tanya January 2006 (has links)
<p>This thesis assesses the uptake of the national Prevention of Mother to Child Transmission of HIV (PMTCT) programme in South Africa, and the challenges of achieving safe infant feeding practices in the context of HIV. The research studies contained in this thesis utilised a variety of quantitative and qualitative research methods in order to provide a full understanding of the challenges of moving from efficacy to effectiveness in PMTCT programmes. The first paper utilised a cross-sectional approach to a programme evaluation, papers two and three utilised qualitative methodologies, and paper four was based on a longitudinal cohort study design. The findings highlight the low uptake of PMTCT interventions and inappropriate infant feeding choices. The experiences of women with HIV provide an important insight into the difficulties of operationalising the WHO/UNICEF HIV and infant feeding recommendations in real life settings, where rates of HIV disclosure are low and mixed feeding is the norm. Several personal and environmental characteristics were identified that contributed to success in maintaining exclusive infant feeding practices. The research provides some guidance on the definition of appropriateness in infant feeding choices, and highlights the poor outcomes associated with formula feeding under unsafe conditions. Modifying infant feeding practices is essential in order to reduce postnatal HIV transmission and improve child survival. Interventions to improve infant feeding need to include improving the quality of counselling and support provided by health workers, with more structured assessments used to guide infant feeding choices. Efforts are also needed at the community level to increase rates of disclosure and to promote exclusive infant feeding as a norm.</p>

Health and Nutrition in the Tarahumara of Northern Mexico : Studies among Women and Children / Hälsa och nutrition hos Tarahumara indianer i Norra Mexiko : Studier på kvinnor och barn

Monárrez-Espino, Joel January 2004 (has links)
<p>Belonging to an indigenous group in Mexico is usually associated with poor health, mainly as the result of social isolation from the mainstream society. The Tarahumara are no exception. They constitute the largest indigenous group in northern Mexico and one of the most marginalized ethnic minorities in North America. Health conditions are precarious, yet very little data are available to facilitate the design and implementation of programs to prevent and manage the main public health problems affecting this people. This thesis aims at overcoming part of this information gap. It presents and discusses the results from studies focusing on the nutrition of women and children carried out between 1997 and 2002.</p><p>A survey in a representative district sample of Tarahumara women of reproductive age found the highest prevalence of anemia among pregnant women in their third trimester (38.5%) and those lactating during the first 6 months after delivery (42.9%), along with a high prevalence of iron deficiency. In this study a technique was developed to collect capillary serum samples spotted onto filter paper to measure serum ferritin in remote settings. In the same study, 52.5% of adult women were overweight, suggesting a process of ‘de-Indianization’ of their traditional diet and activity patterns. This issue was followed-up in a later study based on perceptions of food and body shape using cognitive anthropological methods. Speaking Spanish emerged as a clear indication of acculturation that could be associated with an increase in the prevalence of obesity and its consequences. A nutrition survey among Tarahumara children at boarding schools found evidence of zinc, vitamin B<sub>12</sub>, iron, and iodine deficiencies but found similar anthropometric status to other rural Mexicans. Finally, a qualitative assessment was carried out to identify culturally accepted foods to redesign a food aid basket aimed at alleviating malnutrition among young Tarahumara children.</p><p>The results from this thesis provide relevant data for an improved design of interventions to combat and prevent some of the nutritional problems that affect the Tarahumara. These data could also constitute a baseline to which future changes can be compared if similar sampling strategies are used. Overall, the findings highlight the importance and challenge of achieving modernization in a way that not only improves health but at the same time supports, maintains and encourages traditional cultural values. These are not only the foundations of the Tarahumara society, but in some cases also contribute to a better diet and health.</p> / <p>Die Zugehörigkeit zu einer eingeborenen Volksgemeinschaft Mexikos wird gewöhnlich mit einem schlechten Gesundheitszustand, aufgrund sozialer Isolation von der allgemeinen Gesellschaft, verbunden.

Bei dieser Studie wurde eine Feldtechnik für weit entfernte Gebiete entwickelt, um die Ferritin-Konzentration in Kapillar-Serum auf Filter Papier zu messen.

Pero sobre todo, los hallazgos apuntan a la importancia y el desafío para alcanzar una modernización que no solo mejore la salud de los indígenas, sino que además apoye, mantenga y promueva los valores culturales tradicionales, pues estos, además de conformar los cimientos de la sociedad Tarahumara, pueden en varios casos contribuir a una mejor nutrición y salud.
