- Description: Municipal waste and sanitation workers (street sweepers, latrine cleaners, and waste transporters) play a crucial role in maintaining public health by providing a safe and clean environment. They accomplish this by performing tasks such as sweeping streets, collecting domestic waste regularly, pit latrine cleaning, cleaning public toilets, and operating waste collection trucks. Nonetheless, they play an important role in mitigating health-related challenges by ensuring a clean and healthy environment through correct waste collection and disposal practices. Therefore, safe waste collection is a critical undertaking that safeguards the health and living conditions of individuals worldwide. However, their hygiene-related knowledge and practices remain low due to a lack of educational intervention programmes on hygiene. Therefore, the study investigated the impact of an educational intervention on hygiene knowledge and practices amongst municipal waste and sanitation workers in Nelson Mandela Bay Municipality (NMBM). The study used a quasi-experimental study, one group, (pre- and post-test) design, using an educational intervention. A total of 201 municipal waste and sanitation workers were conveniently sampled in the study from all five municipal waste depots and six wastewater treatment plants in the NMBM. A self-administered, structured, hard-copy questionnaire was used to collect the participants’ demographic data and a pre-intervention assessment on hygiene-related knowledge and practices. An educational intervention based on existing literature and national environmental cleaning guidelines and policies was implemented, and after a minimum gap of two months following the intervention, participants were asked to complete the postintervention questionnaire. The collected data was captured in a QuestionPro survey platform and analysed in Microsoft Office 365 (2019 version) and R software (version 4.4.1). The knowledge and practice items were further evaluated for internal reliability using the Cronbach’s alpha technique. Inferential statistics were used to analyse and describe the data, including tests such as Pearson’s correlations, student t-tests, analysis of variance (ANOVA) and multivariable linear regression analysis. A total of 201 participants, comprising 148 (73.6%) males and 53 (26.4%) females, participated in the study. Of the 201 participants, 95 (47.3%) indicated that 2 they had never heard of hygiene-related diseases. The study participants had poor knowledge and practices regarding hygiene prior to the educational intervention. Based on the paired samples t-test, there was a significant difference post-intervention phase in the mean scores for hygiene knowledge of 4.0 (±4.8), p<0.001 as well as hygiene practice scores of 4.3 (±3.4), p<0.001. Output obtained from the multivariable linear regression analysis revealed that participants working in Depot (A) (β=-2.82, p=0.005) were less knowledgeable about hygiene compared to those in Depot (B) in the pre-intervention phase. Participants who have not heard of hygiene-related diseases (β=-3.05, p<0.001) were significantly less knowledgeable about hygiene than their counterparts who have previously heard about hygiene-related diseases. Participants older than 51 years of age had poorer knowledge (b=-0.09, p=0.919) regarding hygiene when compared to the participants who were 18-30 years old. Furthermore, only female participants (b=1.44, p=0.022) and the Coloured ethnic group (b=1.44, p=0.050) had good hygiene practices when handling waste, compared to male participants and those of Black African ethnicity. The study's findings highlight the significant positive impact of an implemented educational intervention programme amongst municipal waste and sanitation workers on improving their knowledge of hygiene-related diseases and hygiene practices when discharging their duties. However, predictor factors such as working environment, educational training background, age, and race significantly influenced the impact of the implemented educational programme. The ongoing implementation of similar initiatives is highly recommended amongst municipal waste and sanitation workers, thus preventing hygiene-related infections amongst the studied population and fostering a healthier environment. , Thesis (MSc) -- Faculty of Science, School of Behavioural & Lifestyle Sciences, 2024

- Description: South Africa has experienced a high and rising burden of non-communicable diseases (NCDs) and lifestyle risk factors over the past decade. Health as a category of human capital is generally ex-pected to influence an individual’s labour supply and productivity. Despite the increasing burden of non-communicable diseases, the high rate of economically inactive population and persistent wage inequalities in South Africa, there is limited empirical research on the effect of NCDs on labour force participation, employment status and wage differentials. Given this, the main object-ive of this study was to determine the effects of NCDs on three labour market outcomes: labour force participation, employment status and wage differentials in South Africa. This was divided into three major analytical objectives. Data used was extracted from the five waves of the National Income Dynamics Study, a nationally representative survey collected by the South African Labour and Development Research Unit (SALDRU). Several econometric tests, including cross-sectional data analysis, panel data analysis and the Blinder-Oaxaca decomposition methods, were used in the study. The first analytical objective focused on estimating the effect of lifestyle risk factors on labour force participation through NCDs by gender. Endogenous multivariate probit models with a recur-sive simultaneous structure were employed as a method of analysis. The empirical findings suggested that NCDs and associated risk factors have detrimental effect on labour force participation. The analysis was further expanded to analyse the effect of gender differences, considering that the effect of NCDs may be gender-specific. The results revealed that the effect of stroke and heart diseases were significant only for men, while diabetes and high blood pressure were only significant for women. The results also emphasised the significant indirect influence of obesity, physical inactivity, and alcohol consumption on labour force participation through NCDs, especially for men. The second analytical chapter focused on investigating the effect of NCDs on employment status – that is, those employed, unemployed and economically inactive in the population of South Africa by gender. The estimation technique known as generalised linear latent and mixed methods (GLLAMM) was employed to fit the multinomial logit model with correlated random intercept. The findings suggest that NCDs affect the economically inactive population significantly relative to those employed, and the magnitude is larger for women than for men. There was no significant difference found in the effect of NCDs on the unemployed relative to the employed segment of the population. In addition, the results revealed gender differences on the effect of NCDs on employment status and that stroke had a significant influence on the employment status of both sexes, while heart diseases had significant influence only in men, whereas diabetes had significant effects only in women. The last analytical chapter focuses on estimating the effect of NCDs on wage differentials in South Africa by gender. The recentred influence function regression model and Blinder-Oaxaca de-composition with RIF were used in the chapter. The empirical results revealed that the effect of NCDs on earnings differ by gender. It was found that women with NCDs earn less than those without NCDs, while men with NCDs were found to earn more than their counterparts without NCDs. The results further revealed that women with NCDs suffer from wage discrimination in South Africa. The policy implications of this study are gender-specific. The results highlight the necessity for undertaking a massive awareness campaign regarding the prevention and control of NCDs, espe-cially among women. This can be achieved through specific female health programmes, including maternal healthcare. The findings of the study imply largely that calls for gender-responsive health approaches which take into account gender-specific needs and priorities should be promoted, compared to a blanket approach. In addition, there is a need for the government to complement education policies to promote labour market outcomes. Policies aimed at increasing access to education should continue to improve access to higher education and so to enhance participation in the labour force and reduce wage gaps. , Thesis (PhD) -- Faculty of Management and Commerce, 2020
