The prevalence of insufficient iodine intake in pregnancy in Africa: protocol for a systematic review and meta-analysis
Get PDFBackground: Insufficient iodine intake in pregnancy is associated with many adverse pregnancy outcomes. About 90% of African countries are at risk of iodine deficiency due to poor soils and dietary goitrogens. Pregnancy predisposes to insufficient iodine nutrition secondary to increased physiological demand and increased renal loss. Iodine deficiency is re-emerging in countries thought to be replete with pregnant women being the most affected. This review seeks to identify the degree of iodine nutrition in pregnancy on the entire African continent before and after the implementation of national iodization programmes. Methods: A systematic search of published literature will be conducted for observational studies that directly determined the prevalence of insufficient iodine intake among pregnant women in Africa. Electronic databases and grey literature will be searched for baseline data before the implementation of population-based iodine supplementation and for follow-up data up to December 2018. Screening of identified articles and data extraction will be conducted independently by two investigators. Risk of bias and methodological quality of the included studies will be assessed using a risk of bias tool. Appropriate meta-analytic techniques will be used to pool prevalence estimates from studies with similar features, overall and by major characteristics including the region of the study, time period (before and after implementation of iodization programmes), sample size and age. Heterogeneity of the estimates across studies will be quantified and publication bias investigated. This protocol is reported according to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines. Discussion: This review will help ascertain the impact of national iodization programmes on the iodine nutrition status in pregnancy in Africa and advise policy on the necessity for monitoring and mitigating iodine deficiency in pregnancy in Africa. This review is part of a thesis that will be submitted to the Faculty of Health Sciences, University of Cape Town, for the award of a PhD in Medicine whose protocol has been granted ethics approval (UCT HREC 135/2018). In addition, the results will be published in a peer-reviewed journal. Systematic review registration: PROSPERO CRD42018099434 Keywords: Iodine, Insufficiency, Pregnancy, Afric

No full textAbstract text To effectively reduce HIV transmission to newborns requires a reduction of HIV prevalence among pregnant women and a full understanding of its epidemiology. There is however, a literature gap: few recent HIV studies focus on women attending antenatal care in rural areas in South Africa. A Cross-sectional study of women attending antenatal care in four Primary Care facilities was conducted. An interviewer-administered questionnaire to collect information on socio-demographic characteristics and medical history was used. Binomial logistic regression analyses were used to determine factors associated with HIV and to estimate the prevalence ratio (PR). The 95% confidence interval (CI) is used for precision of estimates; p≤0.05 for statistical significance. A total of 343 participants were recruited. Most participants (n = 341 or 99.42%; CI: 97.91 – 99.93) knew their HIV status. The antenatal HIV prevalence was 38.19% (CI: 33.17 – 43.48). Participants older than 40 years were 3.99 and 3.81 times more likely to be HIV positive compared to teenagers (PR = 3.99; CI: 1.11 – 14.30; pstxvalue = 0.034) and those in the 20-29 age group (PR = 3.81; CI: 1.07 – 13.60; pstxvaluevalue = 0.039) respectively; and this was statistically significant. Unemployed participants were 34% (PR = 1.34; CI: 1.16 – 1.55; p-value less than 0.0001) and 41 percent (PR = 1.41; CI: 1.23 – 1.61; p-value less than 0.0001) more likely to be HIV positive when compared to tertiary students and self-employed individuals respectively. The antenatal HIV prevalence remains high and is increasing in this population. However, findings suggest a changing and maturing epidemic.Thesis (MMED) -- Faculty of Health Sciences, 201
Barriers Inhibiting the Implementation of Gender Equity and Accessibility of Female Teachers to Management Positions in Oliver Reginald Tambo Inland District
Get PDFABSTRACT This study sought to establish ways of dealing with stress as experienced by primary school teachers. Stress is a global phenomenon that affects everyone regardless of gender, resources and environment. Although this phenomenon is well researched, it remains a worrying challenge particularly to schools’ effectiveness. Teachers face many challenges in South African schools such as the ill-discipline of learners and overcrowding of schools. It is vital that schools come up with better intervention programs that can assist teachers to overcome stress. This study involved qualitative approach method and a case study design was used for sampling purposes in which five (5) post level 1 Mathematics teachers from different schools responded to interviews. Data were analysed using categories or themes. The findings of this study revealed that stressful experiences of primary school teachers were overcrowding, infrastructure, lack of parental involvement and lack of reliability in doing homework and extra-co-curriculum activities. It is recommended that the school disciplinary committees should be trained in various disciplinary measures that can be implemented in the school to curb learner ill-discipline and lack of commitment. It is also recommended that a working relationship should be built properly between the school and the Department of Basic Education, motivational speakers and educational counsellors should meet with all learners to motivate them to have high desire for and interest in education and to build their self-confidence in the classroom.
