The purpose of this study was to assess the epidemiology of preventable risk factors for NCDs among the adult population in Tigray, Northern Ethiopia. A quantitative descriptive cross-sectional design was employed to describe the distribution of behavioural and biological risk factors for NCDs, assess the status of knowledge, perceptions, attitude and behaviour of the study participants for NCDs and their risk factors, and a matched case-control study to identify the determinants of hypertension. The data was collected using a structured questionnaire for the interview, physical measurements including weight and height scales, non-elastic measuring tape for waist and hip circumferences, Omron digital BP apparatus for blood pressure and heart rate; Accutrend Plus for measuring fasting blood glucose, cholesterol and triglycerides. For the descriptive cross-sectional study a total of 2347 participants were included, and for the matched case control study a total of 117 cases and 235 controls participated. Behavioural and biological risk factors were assessed. Only 0.8% of the study participants used optimal fruit serving per day. The prevalence of low level physical activity (<600 MET-minutes/week) was 44.8%. The magnitude of ever alcohol consumption was 66.8%. However, the magnitude of khat chewing and tobacco smoking among the study participants was not as high as the other risk factors i.e. 3.3% and 2.3% respectively. The magnitude of hypertension, central obesity, hyperglycaemia, hypercholesterolemia and hypertriglyceridemia was 9.9%, 22.2%, 3.5%, 30.3% and 32.2% respectively. Factors associated with the risks aforementioned were gender, age, place of residence, education, knowledge status on NCDs, mental stress and others. The status of knowledge on CVDs, breast and cervical cancers, diabetes and their potential risk factors was low and not comprehensive. Misconceptions on NCDs and body size and shape were pervasive. Risky behaviours underlying NCDs were rampant in the study population. Factors related to poor knowledge on NCDs were gender, age, place of residence, education and misconceptions on NCDs. The determinants of hypertension were physical inactivity, duration of alcohol intake, central obesity and mental stress. Awareness raising interventions on NCDs and their risk factors; improving socio-economic status and accessibility to health care settings have to be in place to curb these formidable problems. / Health Studies / D.

Thesis (MMed (Occupational Medicine))--Stellenbosch University, 2013. / Introduction Exposure incidents involving blood and body fluids represent a major hazard for medical undergraduates. Every medical teaching university experiences the problem of undergraduate medical students sustaining such incidents. Although Post Exposure Prophylaxis (PEP) is readily available and accessible to medical undergraduates following an incident, continuity and quality of care extends beyond the provision of PEP. This includes follow up consultations after receiving PEP according to protocol. Study Design This study was performed at the Tygerberg Campus of Stellenbosch University in Cape Town, South Africa to assess compliance with follow up consultations following an exposure incident. The study base consisted of all the medical undergraduates who reported an exposure incident at the Campus Health clinic. Cases were defined as medical undergraduate students of Stellenbosch University who had reported an exposure incident between January 2007 and December 2011. They were identified using the clinic database and records. Influential factors associated with the exposure incident, including compliance regarding follow up consultations were obtained from standardised reporting forms and medical records. The data was analysed in 2 sections, a cross sectional component (descriptive and analytical) and a retrospective cohort component. Two student cohorts were retrospectively followed from the beginning of their 3rd year to the end of their medical curriculum (6th year). Results There were 280 exposure incidents reported in the study period, of which 174 were low risk and were 106 high risk incidents for which PEP was prescribed (37.86% used PEP). For those who had high risk exposures, 90.57% (n=96) attended the 6-week follow up consultation, 48.11% (n=51) attended the 3 month visit and 34.91% (n=37) attended the 6 month follow up visit. There was an increase in the number of exposure incidents from 2010 (n=43) to 2011 (n=76). Internal medicine accounted for the most number of incidents (n=68), followed by Surgery (n=51), Obstetrics and Gynaecology (n=44), and Paediatrics (n=42). Drawing blood was the most common reported activity associated with exposures. Of notable importance was recapping, disposing of needles and insertion of blood into sample tubes. These activities accounted for 63 of the 280 exposure incidents. The 4th year students were the least at risk for exposure incidents compared to 3rd, 5th, 6th years. The annual average cumulative risk of having an exposure incident was found to be 5.7% (95%CI=4%-8%) and 6.8% (95%CI=5%-9%) amongst the 2 student cohorts over the duration of 4 years (clinical exposure time). Recommendations There is an urgent need for the number of exposure incidents to be reduced, e.g. needle recapping and disposal, and insertion of blood in sample tubes cause numerous preventable incidents. Various other strategies can be implemented in order to reduce the number of incidents across all undergraduate years of study. It is envisaged that by reducing the number of exposure incidents, there will be a subsequent decrease in the number of individuals requiring PEP. The importance of ensuring compliance with regard to follow up consultations needs to be emphasized. Factors that lead to noncompliance need to be investigated in a separate study.

A medicina de viagem (MV) surgiu em resposta ao crescente deslocamento populacional, com o objetivo de prevenir os agravos à saúde relacionados às viagens. No Brasil teve inicio no final da década de 90, momento em que reformas socioeconômicas levaram a melhorias das condições de vida dos brasileiros. O Núcleo de Medicina do Viajante (NMV), do Instituto de Infectologia Emilio Ribas (IIER), foi o primeiro serviço de atenção à saúde do viajante criado na cidade de São Paulo, em maio de 2000. O presente estudo visa: descrever a população de viajantes que procuraram orientação pré-viagem no Núcleo de Medicina do Viajante (NMV) do Instituto de Infectologia Emilio Ribas (IIER) no período de janeiro de 2006 a dezembro de 2010; descrever as medidas de prevenção recomendadas em relação às doenças infecciosas; descrever as atividades de ensino realizadas e a participação do serviço na discussão de diretrizes em políticas públicas em medicina de viagem. No período estudado, 2744 viajantes procuraram orientação pré-viagem no NMV do IIER. Foram realizados 2836 atendimentos de orientação pré-viagem, 92 viajantes procuraram o serviço mais de uma vez. A faixa etária entre 18 e 34 anos (54,2%), o sexo feminino (51,1%) e grau de educação superior (75,5%) foram as principais características demográficas desses viajantes. Os destinos mais procurados foram: África (24,5%), Europa (21,2%), Ásia (16,6%) e Brasil (19,2%). O turismo (35,7%) e o trabalho (35,7%) foram os motivos de viagem mais referidos. O tempo de permanência menor ou igual a 30 dias foi referido pelos viajantes em que o objetivo de viagem foi o turismo, enquanto os viajantes que referiram o trabalho ou estudo apresentaram maior tempo de permanência (p < 0,001). O meio de transporte mais referido foi o aéreo (62,8%). Os viajantes relataram durante a consulta pré-viagem dificuldade de acesso ao serviço. As fontes de informação mais referidas foram: informação a partir de amigos, indicação por profissional da saúde e mídia eletrônica. As medidas de prevenção recomendadas variaram conforme o destino. O tratamento autoadministrado para diarreia foi mais recomendado aos viajantes com destino à Ásia. As vacinas de febre amarela, poliomielite e antimeningocócica A e C foram mais recomendadas aos viajantes com destino à África, assim como a quimioprofilaxia para malária, que foi recomendada para 26,4% dos viajantes para esse destino. A quimioprofilaxia (QPX) para malária foi recomendada em 10,3% de todas as orientações. Houve diferença com significância estatística na recomendação segundo a finalidade (p < 0,30), o destino (p < 0,001) e a duração da viagem (p < 0,001). Das 422 orientações realizadas aos viajantes com destino ao Brasil, a QPX foi recomendada somente para 30 (7,1%). Dos 2744 viajantes atendidos, 664 (24,2%) relataram pelo menos uma morbidade prévia; 66 (2,4%) eram menores de 10 anos de idade; e 157 (5,7%) tinham 60 anos ou mais. Em relação às atividades de ensino, no período do estudo, 83 médicos residentes estagiaram no NMV e foram orientadas onze monografias de conclusão de residência médica. O NMV participou de 12 reuniões para discussão de diretrizes sobre a saúde do viajante e de iniciativas como a Carta de São Paulo (documento em defesa da saúde do viajante elaborado por acadêmicos e profissionais de saúde participantes do SUS). Da criação da Sociedade Brasileira de Medicina de Viagem e da criação do Comitê Estadual de Saúde do Viajante, pela Secretaria de Estado da Saúde de São Paulo. Essas atividades foram passos decisivos para corroborar a implementação de políticas públicas em saúde do viajante no Brasil / Travel medicine (TM) arose in response to the growing population displacement and its objective is the prevention of health problems related to travel. Began in Brazil in the in the late 1990s, at which socioeconomic reforms have led to improvements in of life of Brazilians. Travel Medicine Center (TMC) at \"Instituto de Infectologia Emilio Ribas\" (IIER) was the first health of traveler service created in São Paulo city in May 2000. The present study aims: to describe the traveler population who sought pre-travel guidance in TMC at IIER from January 2006 to December 2010; to describe the recommended preventive measures to travelers concerned with infectious diseases; to describe the teaching activities performed and the service involvement in debating guidelines about public policies in travel medicine. In the time period studied, a total of 2744 travelers sought pre-travel guidance in TMC of IIER, but 2836 assistances were provided for pre-trip orientation since 92 travelers sought the service more than once. The age group between 18-34 years (54.2%), female (51.1%), and university level degree (75.5%) were the main demographic characteristics. The more popular destinations were: Africa (24.5%), Europe (21.2%), Asia (16.6%) and Brazil (19.2%). Tourism (35.7%) and work (35.7%) were the main purposes of trip for travelers. For tourism purpose travelers would stay 30 or less days, while for work or study they stayed for a longer time (p <0,001). Commercial air travel was the preferred alternative (62.8%). The main sources of information were friends, health professionals, and electronic media. The recommended preventive measures varied according to the destination. The self-treatment for diarrhea was more recommended for travelers to Asia. Vaccination against yellow fever, polio, and anti-meningococcal (A and C) was more recommended for travelers to Africa, as well as chemoprophylaxis (CP) of malaria was recommended for 26.4% of travelers to the same country. The CP of malaria was indicated for 10.3% of all assistances. There was statistically significant difference in the recommendation according to purpose (p < 030), destination (p < 0.001) and trip duration (p < 0.001). From 422 assistances to travelers to Brazil, CP was only recommended for 30 (7.1%) travelers. From the 2744 travelers assisted, 664 (24.2%) reported at least one previous morbidity; 66 (2.4%) were under age 10; and 157 (5.7%) were 60 years or older. During the research period and relating to study activities, 83 residents were interns in TMC, and eleven monographs for completion of the Medical Residency were supervised. TMC participated in 12 meetings to discuss guidelines in travel medicine, and participated in initiatives such as \"Carta de São Paulo\" (a document in defense of traveler health prepared by academics and health professionals participating in the Unified Health System); in the institution of the Brazilian Society of Travel Medicine, and of the São Paulo State Travel Medicine Committee by the Secretariat for Health of São Paulo State. These were decisive steps to support implementation of public policies in traveler health in Brazil

The lack of a contextualised, relevant communication strategy focusing specifically on HAST diseases in the Limpopo Province was the impetus for this research. The purpose of this study was, therefore, to explore the knowledge, perceptions and utilisation of health facilities for HAST in order to develop an acceptable and effective communication strategy for the Province to address the high rate of HAST diseases. The study followed a qualitative approach guided by the major tenets of the Health Belief Model, namely, to determine modifying factors, individual beliefs and cues for action. An in-depth literature review was followed by focus group interviews with the community members and personal interviews with District and Provincial Deputy Directors. Based on these findings, a communication strategy was drafted and piloted for three months in one of the districts in Limpopo. Further refinement of the communication strategy followed after member-checking and further interviews with directors HAST. The final strategy specifically focused on risk groups with each of the diseases in terms of their beliefs and perceptions. It further resulted in guidelines for health providers in terms of the content and implementation of effective communication strategies within the context of educational, cultural, social and economic factors relevant to Limpopo / Health Studies / D.

Thesis in English, Annexure E: Consent form (leaf 81) as well as KABP Survey Questionnaire (leaves 87-91) in English and SiSwati. / The purpose of the study was to assess knowledge, explore attitudes and determine practices of breastfeeding mothers living with HIV regarding post-natal PMTCT interventions and services. The study was quantitative and descriptive in nature, utilising a retrospective cohort design. The study sample included breastfeeding mothers living with HIV, who attended the King Sobhuza II public health unit in the Manzini region of Swaziland. A written questionnaire was administered to a non-random sample of 90 consecutively selected mothers living with HIV attending the above-cited public health unit for post-natal health purposes. The overall study results revealed that the majority of breastfeeding mothers living with HIV in the afore-mentioned region (77.8%) presented high levels of knowledge on PMTCT, and 90% demonstrated a positive attitude; while a further 90% also demonstrated positive behaviour towards PMTCT. However, stigma and discrimination among family members, non-disclosure of HIV status to sexual partners; as well as poverty and fear of future drug-resistance are the cause of non-adherence to ARV prophylaxis. Furthermore, inconsistent condom use, mixed-feeding methods and wet-nursing also emerged as other contributing factors to the increase of post-natal mother-to-child transmission of HIV among breastfeeding mothers living with HIV. / Health Studies / M.A. (Nursing Science)

In its efforts to reduce maternal mortality and prevent Mother-to-Child Transmission of HIV, the government of Swaziland developed and implemented several programmes including a special antenatal care package for HIV-positive pregnant women in line with the WHO (2009) guidelines. Since the implementation of this latest special ANC package for HIV-positive women, little is known about how these services are experienced by the intended recipients. The purpose of this study was to explore and describe the actual experiences of HIV-positive women with the antenatal care services provided at a regional referral hospital in Swaziland, with the view of providing more insight into the quality of ANC services from the users' perspectives. A qualitative descriptive, exploratory design was used to address the above purpose. The researcher used purposive sampling to select the participants who met the inclusion criteria for the study. Semi-structured individual interviews were used and saturation was reached after 18 individual face-to-face interviews. Thematic content analysis was used to analyse the collected data. Forteen themes related to the participants experiences with the ANC services and seven related to measures for improvement emerged from data. In general HIV positive pregnant women expressed positive views towards ANC services they received at the target institution. The results give an indication on the quality of the focussed ANC package provided at the hospital and specific recommendations for improvement are outlined. / Health Studies / M. A.

Text in English / This qualitative descriptive phenomenological study explored the experiences of HIV positive women utilising PMTCT services at a central hospital in Zimbabwe. Data was collected using in-depth interviews of fifteen participants. The interviews were audio recorded and transcribed verbatim. Using the Interpretive Phenomenological Analysis framework for data analysis, two super-ordinate themes emerged, namely resources for provision of PMTCT services and approaches and nature of PMTCT care. The study revealed challenges experienced by HIV positive women emanating from material, financial and human resource related constraints in the PMTCT setting. The resource challenges negatively affected access and utilisation of PMTCT services. A practice model, whose purpose is to enhance the quality and utilisation of PMTCT services, was developed and described. The model was evaluated using Chin and Krammer (2011) criteria plus a modified form of the Delphi technique. These findings have implications for effective PMTCT service provision. The key lessons learnt for programmatic improvement were that in order to provide quality and accessible PMTCT services the health care system will need to be well resourced. There is need to strengthen the health care system in line with HIV related programmatic changes. / Health Studies / D. L.itt. et Phil. (Health Studies)

Millions of deaths in the world are a result of these diseases, and this number has increased each year. In an attempt to change this scenario WHO has stimulated regular practice of physical activities, because they play an important role in preventing CNCDs. In Brazil, these activities are performed by health units which generate a large amount of data that need treatment. To deal with this problem we developed UCEMEPA, an environment that employs Ubiquitous Computing technologies and wireless communication networks, in order to monitor remotely and evaluate participants of physical activity groups in real-time. This environment automatically collects physiologic data, and provides indicators which will support and direct public policies for promoting physical activity. In this sense, UCEMEPA will contribute for the promotion of health and quality of life, and for the conduction of longitudinal studies aiming to establish correlations between the practice of physical activity and CNCDs prevention. / A inatividade física tem sido apontada pela Organização Mundial de Saúde (OMS) como um dos principais fatores de risco comportamentais responsáveis pela incidência de Doenças Crônicas Não Transmissíveis (DCNTs). Milhões de mortes no mundo são decorrentes dessas doenças e esse número vem aumentando a cada ano. Na tentativa de reverter esse quadro a OMS vem estimulando as práticas regulares de atividade física, já que estas possuem um importante papel na prevenção de DCNTs. No Brasil a promoção dessas atividades é realizada por unidades regionalizadas de saúde e geram uma grande quantidade de dados que carecem de processamento e tratamento. Em resposta a esse problema nós desenvolvemos o ACUMAAF, um ambiente que emprega tecnologias emergentes da Computação Ubíqua e redes de comunicação sem fio para monitorar e avaliar, em tempo real e a distância, participantes de grupos de atividade física. Esse ambiente coleta dados fisiológicos de forma automática e coletiva e tem como objetivo possibilitar a geração de indicadores capazes de apoiar e nortear políticas públicas de promoção de atividade física. O ACUMAAF é um ambiente computacional com contribuições para a promoção da saúde, para a promoção da qualidade de vida da população e para a realização de estudos longitudinais objetivando relacionar atividade física e a prevenção de DCNTs.
