Assessing the effectiveness of integrated non-communicable disease and antiretroviral adherence clubs in Cape Town, South Africa

Gausi, Blessings 10 September 2020 (has links)
The growing burden of HIV and non- communicable disease (NCD) syndemic in Sub Saharan Africa, has necessitated introduction of integrated models of care in order to leverage existing HIV care infrastructure for NCDs. However, there is paucity of literature on long term treatment outcomes for multimorbid patients attending integrated care. We describe long term treatment outcomes among multimorbid patients who attended integrated ART and NCD clubs (IC), a novel model of care piloted in 2014 by the Western Cape Government in South Africa. We followed up multimorbid patients for 12 months, who enrolled for IC at Matthew Goniwe and Town II clinics before September 2016. Median adherence proportions, HIV viral suppression and retention rates were calculated at 12 months before and after IC enrolment. Rates for achieving targets for blood pressure and glycosylated haemoglobin were determined at 12 months prior, at IC enrolment and at 12 months post IC enrolment. We describe demographic and clinical variables among all patients at IC enrolment and used multivariable logistic regression to evaluate for predictors of NCD control 12 months post IC enrolment. As of 31 August 2017, 247 patients in total had been enrolled into IC for at least 12 months. Of these, 221 (89.5%) had hypertension, 4 (1.6%) had diabetes mellitus and 22 (8.9%) had both in addition to HIV. Adherence was maintained before and after IC enrolment with median adherence proportions of 1 (IQR 1-1) and 1 (IQR 1-1) respectively. HIV viral suppression rates were 98.6%, 99.5% and 99.4% at the three time points respectively. Retention in care was high with 6.9% lost to follow up at 12 months post IC enrolment. Optimal blood pressure control was achieved in 43.1%, 58.9% and 49.4% of participants whereas optimal glycaemic control was achieved in 47.4%, 87.5% and 53.3% of diabetic participants at the three time points respectively. Multivariable logistic analyses showed no independent variables significantly associated with NCD control. Multi-morbid people living with HIV achieved high levels of HIV control in integrated HIV and NCD clubs. However, intensified interventions are needed to maintain NCD control in the long term.

Alcohol and problem drinking as risk factors for tuberculosis

Mkandawire, Tiwonge Jaranthowa January 2009 (has links)
Includes bibliographical references. / [Background] Tuberculosis is a major public health concern for South Africa which has one of the highest recorded incidence rates in the world. Previous research [1998 South African Demographic and Health Survey (SADHS)] reported a crude association between alcohol use and tuberculosis. This study aimed to examine evidence for a relationship, and the size thereof, between alcohol consumption and previous tuberculosis in the 2003 SADHS as a means of informing tuberculosis prevention. [ Methods ] This study was a secondary analysis of cross sectional data collected as part of the 2003 SADHS. Tuberculosis lifetime risk was derived from respondent reports of past tuberculosis episodes based on being informed by a healthcare worker. Alcohol consumption, problem drinking as well as selected explanatory variables were generated from similar questions from the adult questionnaire of the SADHS. The CAGE questionnaire was used to measure symptoms of alcohol problems. Logistic regression was used to model the relationship between past tuberculosis and both alcohol consumption and CAGE. [ Results ] Current and previous alcohol consumption were found to be associated with an increase in odds of tuberculosis in both men and women, with odds ratios ranging iii from 1.1 (95% CI 0.9 - 2.5) to 2.8 (95% CI 1.4 - 5.7) after adjusting for potential confounding effects of socioeconomic factors, smoking, nutritional status and age. Having a CAGE score of either 1 to 2 or 3 to 4 was associated with a doubling [OR 2.2 (95% CI 1.0 - 4.8) and quadrupling [OR 4.4 (95% CI 1.4 - 13.4)] in the odds of tuberculosis respectively. [ Discussion ] and conclusion Behavioural and biological mechanisms of effect of alcohol on tuberculosis may explain the findings. Impairment of the immune system, both acute and long term, has been suggested as the mechanism of increased susceptibility to tuberculosis. On the other hand, high risk living conditions and behaviour associated with problem drinking provide potential for increased exposure and susceptibility to tuberculosis infection. The study was able to control for several potentially confounding socioeconomic predictor variables although not HIV infection. The results complement a body of research that has documented the adverse effects of alcohol consumption on health in general and tuberculosis specifically. The findings thus provide more evidence for public health practitioners to tackle the problem of tuberculosis via specific efforts to control alcohol use and abuse, in addition to other methods of tuberculosis control.

Predicting poor outcome Crohn's disease at the time of first diagnosis

Watermeyer, Gillian January 2013 (has links)
Over time, the majority of patients with Crohn's disease (CD) will develop irreversible gastrointestinal (GIT) damage, notably strictures or fistulas, impacting negatively on quality of life and resulting in hospitilisation and surgery. Early and aggressive drug therapy with immunomodulators (IMMs) and biologics may alter the likelihood of these complications and improve long-term outcomes. However, this approach is extremely expensive and carries its own battery of side-effects such as infections and malignancy. In addition there are a sizable number of patients with CD who will have a benign disease course and never require potent medical therapies or surgical intervention. As a result, there has recently been a surge of interest in early identification of those people who are at risk of developing complicated disease. The aim of our study was thus to indentify predictive factors for poor outcome CD in a South African setting, in order to select those who would most benefit from early and aggressive medical therapies.

Determinants of HIV voluntary counselling and testing among the youth: The case of Botswana

Mokalake, Ellen N January 2010 (has links)
Includes bibliographical references. / This study was conducted in Gaborone city, Botswana. Botswana is a small country in south central part of Africa with a population of 1.7 million (Botswana population census, 2001) The overall aim of the study was to examine barriers and facilitating factors influencing the readiness for and acceptability of voluntary HIV testing among the youth aged 18-24 years in Gaborone, Botswana. A quantitative methodology was used in this study. A multistage sampling strategy was also used to recruit one hundred and forty four (144) participants. Information on socio-demographic characteristic, knowledge and utilization of VCT sexual behaviour and perception of risk was gathered by use of a self administered structured questionnaire. STATA version 8 was used to analyse the results of this study. Summary statistics, chi-square test and logistic regression were employed in the analysis. Participants comprised of students from senior secondary schools and tertiary education institutions from the sampled schools of Gaborone. The modal level of education was secondary and the more than half of participants (56%) were females. Their age ranged from 18-24 years. The majority of participants (75%) were sexually active and just over a third 36% of all participants considered themselves not at risk of HIV. VCT knowledge was reported by a significant proportion (59%) who also reported knowledge of VCT sites. HIV testing was reported by a minority of participants 42% and the most commonly reported reason for testing was media campaigns encouraging HIV testing whilst the most commonly reported reason for not testing was never been sexually active. Findings from this study revealed that, HIV test acceptance among the youth is still an area that needs greater attention. The facilitation of HIV testing amongst the young people and removal of barriers to testing can be achieved through a focus on use of strategies that seem vii to work such as the media. Also, there is need to ensure utilization of VCT services by youth through making them understand of the role that VCT plays in preventing HIV and AIDS.

A brief intervention to promote IUD use among women in Cape Town

Trasada, Phumelele January 2013 (has links)
Includes bibliographical references. / While the Copper T intrauterine device (IUD) is one of the most used methods of contraception around the world, only 1% of women in sub-Saharan Africa use this method. The IUD is a safe and highly effective form of long-acting contraception that provides protection for up to 10 years and has a lowrisk of pregnancy (less than 1% during the first year of use). The IUD is highly beneficial in that it can provide protection for women who want to delay or space childbearing and unlike methods such as the injectable or oral contraceptive, does not require users to make numerous visits to their health care facility or obtain a further supply. The IUD is free in the public sector in South Africa, but remains an unpopular choice among women. The purpose of this study was to test the effectiveness of a brief counselling intervention on the uptake of the IUD among women in Cape Town, South Africa. Part A of this dissertation (Protocol) is comprised of a proposal that was accepted by the University of Cape Town (UCT) Human Research Ethics Committee (HREC) and the Provincial Government of the Western Cape (PGWC). It describes the study background and methods. Part B (Literature Review) presents the current state of IUD use in sub-Saharan Africa as well as the level ofunmet need for contraception in the region. It illustrates the effectiveness of the IUD and gives a summary of interventions related to IUD uptake. It also discusses the need for increased use of the long acting and permanent methods in sub-Saharan Africa. Part C (Article) presents the results as a journal article. The incidence of the primary outcome was lower than expected. Five percent of women assigned to the control group went to family planning to make an appointment for IUD insertion, while 4% of those in the intervention group made an IUD insertion appointment. Knowledge of the IUD was not high with only 46% of women having heard of the method. After being given a description of the IUD, 36% of women said they would consider using the IUD. Twenty-seven percent of women stated that they would be interested in receiving an IUD that day. The method was not often mentioned to clients as only 16% reported having discussed the IUD with a health provider. Chi-squared analysis identified characteristics which were related to a participant being aware of the IUD. In this regard, being older and having higher gravidity were both significantly associated factors. The results suggest that IUD is a method that women are interested in learning more about and potentially using. It is clear that a more intensive and comprehensive campaign is needed in order to increase demand for the IUD in South Africa.

Measuring PMTCT effectivenss through HIV free survival in children under 2 years

Sineke, Tembeka January 2015 (has links)
Background: The prevalence of HIV was greater than 30% in the Free State province in South Africa and PMTCT services were widely available at the time the guidelines recommended nevirapine in labour and to the child postpartum. Aim: The aim was to determine the effectiveness of the PMTCT program in the Free State by measuring HIV transmission and HIV-free survival in children less than two years of age. Variables associated with HIV transmission and HIV-free survival including PMTCT uptake by mother, demographic characteristics, type of delivery and breastfeeding status were investigated. Methods: This was a secondary analysis of data collected from a cross sectional community household survey, using multistage cluster sampling. The population was all women who had given birth to a child in the two years prior to the study in the catchment area of three sub-districts that were randomly selected in Free State. All mothers were anonymously tested for HIV and if infected the child was also tested. Trained field workers interviewed mothers, identified children who had died and collected data on variables that could be related to transmission and survival. Logistic regression was used to determine risk factors.

The impact of new women infant children (WIC) package on whole grain consumption of participating children in metro-Atlanta, Georgia

Munyati, Bob Mwiinga January 2015 (has links)
Includes bibliographical references / OPurpose: The purpose of this study is to investigate the impact of the revised Women Infant and Children (WIC) programme on whole grain consumption among WIC participating children. In addition, this study aims to investigate how knowledge on whole grain consumption and/or perceptions on cost of whole grain contribute to consumption. Background: The WIC programme is a supplementary nutrition programme for women, infants and children which seeks to promote the health of women who are pregnant, postpartium and lactating and children up to the age of 5 years. The WIC programme is aimed at low-income women and children facing nutritional risk. This nutritional risk is classified by a number of factors that include anaemia, underweight, overweight, history of pregnancy complication or poor pregnancy outcomes. Women and children facing nutritional risk are provided with services that include supplementary foods, nutrition and education counselling, screening and referral to other health, welfare and social services. Methods: This study is a secondary analysis of the Phase II Emory WIC study that investigated the impact of the new WIC programme on fruit and vegetable consumption among participating women. In addition to this, the primary study also investigated the consumption of whole grain foods. The study population consisted of 77 women and their children that attended routine visits in two Metro-Atlanta WIC clinics. In order to meet the aims of this secondary analysis, this study will firstly undertake a univariate analysis and thereafter simple bivariate analysis intended to determine any associations between exposure/risk factors (i.e. old and new WIC Emory Voucher package) and response variables. In addition to the above analysis, paired-tests will be conducted to determine if there is any statistical significant increase in whole grain consumption between; (a.) baseline and week 1 and (b.) baseline and 4 week. Finally, in order to account for possible confounding not taken into consideration by the aforementioned analysis, this study will use General Estimating Equation (GEE) approach to model the change in whole grain consumption over time (from baseline to 4 weeks). It is anticipated that the above methodology will help answer the objectives of this research. Conclusion: It is hoped that the results of the study will highlight possible socio-economic factors that may lead to greater consumption of whole grain foods and provide recommendations on how to best improve the WIC programme with regard to Whole Grain Foods (WGFs) among participating children.

Recognition of malaria, treatment seeking behaviour and perception of the causes and effects of malaria among women attending antenatal clinic in Mudzi district in Zimbabwe

Kamupira, Mercy G S January 2004 (has links)
Includes bibliographical references. / Malaria is an important public health problem with a high morbidity and mortality in more than 90 malaria endemic countries in the world. The burden of malaria is quite high especially among pregnant women and children under five years of age. There has been little focus on the factors that influence women's responses to malaria control strategies, It is important to establish whether the control measures, health education and the treatment options are available to and utilised by women. They are the caretakers of young children who are particularly vulnerable to severe malaria, and in need of prompt response to the illness, while women themselves are at great risk of severe anaemia and other complications during pregnancy. The purpose of the study is to better understand the role of women in the control and management of malaria at the household level, particularly with respect to women's awareness of transmission, prophylaxis, symptoms, complications, treatment and control of the disease and to provide recommendations to make malaria control programs more gender sensitive and therefore more effective.

Seeing HIV through the eyes of perinatally infected adolescents living with HIV, on antiretroviral treatment

Holele, Pearl January 2012 (has links)
Includes abstract. / Includes bibliographical references. / As perinatally infected adolescents living with HIV (ADLHIV) grow older and gain a greater sense of independence, disclosure issues and adherence to antiretroviral treatment (ART) have become major concerns. However, research on how adolescents view and cope with these challenges remains limited, especially in Sub-Saharan Africa. We explored ADLHIV's understanding of their infection and its perceived effects on their well-being, and ultimately, on their attitude towards life-long adherence to ART.
