>Magister Scientiae - MSc / Scientific studies have shown that chronic diseases of lifestyle (CDL) such as hypertension and diabetes mellitus are major causes of mortality and morbidity, accounting for about 60% of the disease burden globally. Available statistics for Swaziland indicate that hypertension and heart diseases are on the increase and are responsible for 33,540 and 3,146 cases per year respectively. Regular physical activity (PA) is widely recognised as a means for the primary and secondary prevention of CDL due to their multi-factorial beneficial effects on an individual‟s health. Therefore, the aim of this study was to determine PA participation among adults with hypertension in Mbabane, Swaziland and the extent to which they are encouraged to be physically active. A cross-sectional design, utilising quantitative methods was employed in the study and three validated standardised interview administered questionnaires were used to collect data from both hypertensive individuals and health professionals. A sample size of 422 hypertensive individuals and 72 health professionals was included in the study. Statistical Package for Social Sciences (SPSS) version 20 was used to analyse the data. Descriptive statistics were employed to summarise data and was expressed as means, standard deviation, frequencies and percentages. The Students‟t-test was used to compare mean age and PA. Chi-square tests were used to test for associations between categorical variables with significant levels set at 5% (p < 0.05). Blood pressure was classified into controlled (≤ 140/≤ 90 mmHg) and uncontrolled (≥ 140/≥ 90 mmHg). PA was dichotomised into active (> 600 MET-minute/week) and sedentary (< 599 METminute/ week). BMI was classified as underweight (<18.5), normal (18.5-24.9), overweight (25-29.9) and obese (>30). The findings of the current study revealed that a considerable number of individuals with hypertension (53%) were physically inactive with poorly controlled blood pressure (57%). A statistical significance was found between mean age and PA (sedentary and active) (P= 0.000 ˂ 0.05). iii The study also revealed that the perceived benefits of PA as reported by individuals with hypertension outweighed the perceived barriers. In addition, the majority of health professionals were found to be poor counsellors of PA (58%). Most health professionals informed their patients on becoming physically active but did not include important components of PA counselling such as the types of PA, intensity and duration. The common reasons for not including PA as part of the daily routine include: not my area of specialty and lack of time. These factors could significantly contribute to sedentary behaviour among hypertensive individuals in developing countries such as Swaziland. For this reason, an urgent need for PA promotion programmes which will motivate hypertensive individuals to participate in sufficient levels of PA as recommended by public health research has been established. The programmes should include educating health professionals on current trends in the promotion of PA. A combination of these approaches will help to reduce morbidity and mortality from cardio-vascular disease (CVD), in particular hypertension.

Masters of Science / There is evidence of the rising incidence and prevalence of chronic diseases of lifestyle in developing countries. It is estimated that by 2020 chronic diseases of lifestyle in Sub-Saharan Africa will be almost 50% of the burden of disease. Rapid urbanization with changes in lifestyle, such as physical activity patterns could explain at least partially the ongoing epidemiological transition. The purpose of this study was to assess levels of participation in physical activity among working Rwandan women in Kigali, in relation to socio-economic demographic characteristics. A cross-sectional study design using both quantitative and qualitative methods was used. Participants' level of participation in physical activity and influence of socio-economic demographic factors on questionnaire adapted from Sub-Saharan African Questionnaire. A focus group discussion assessed the need for a health promotion program related to physical activity participation among working women. Data analysis, using Statistical analysis version 8e, was used to obtain frequency tables and histograms. Chisquare tests and Fisher's exact tests were utilized to test for association between variables. Focus group discussion data were transcribed and translated into English. Data were then coded and put into themes and categories. There were 352 participants, with a mean age of 33.4 years. 71.9% of the participants were classified as sedentary and only 28.1 % of the participants were classified as physically active. Participation in physical activity decreased with age, and there were more participants classified as sedentary people in the married group (77%) than in non-married group (63.2%). A lower level of education and income of participants, the higher the level of participation in physical activity. Among the reported prevalence of chronic diseases, high blood pressure and diabetes were only reported by participants classified as sedentary. During the focus group discussion, participants reported facilitators and benefits of physical activity including, routine, relaxation, socialization and fitness, managing obesity and health purposes. Barriers limiting the participants' ability to engage in physical activity included lack of time, lack of knowledge, laziness, domestic helper, lack of motivation and culture. The main themes, which were identified as important in the development of a health promotion program were: The education and encouragement of girl children; education of women in the community, finding facilities and appropriate venues, a suitable environment and the contribution of physical activity program towards unity and reconciliation was emphasised. The findings of this study demonstrate a problem concerning sedentary lifestyle among the working women in Kigali/Rwanda. It is alarming that the participants who are already classified as sedentary and who will probably experience the consequences of sedentary lifestyle in the future are already reporting chronic diseases like high blood pressure and diabetes. There is therefore an urgent need to design, implement and evaluate a health promotion intervention aimed at promoting a physically active lifestyle in Rwanda.

Thesis (MNutr (Human Nutrition))--University of Stellenbosch, 2006. / INTRODUCTION: The study investigated dietary intake, physical activity and risk for chronic diseases of lifestyle (CDL) among employees at a South African open-cast diamond mine. OBJECTIVES: The aim of the study was to determine the habits and barriers to a healthy lifestyle in order to determine the need for workplace interventions at De Beers Venetia Mine (DB-VM) to decrease the risk for CDL and optimise employee wellness. DESIGN: An analytical, cross-sectional, observational study. SAMPLING: A representative proportional stratified sample of 88 permanent employees at DB-VM was randomly selected to participate in the study. The sample was stratified according to work-shift configuration and occupational category. Permanent employees were limited to subjects with at least six months employment at DB-VM. Temporary employees and contractors were excluded from the sample. METHODS: Subjects were required to complete a validated self-administered sociodemographic-, meal frequency- and physical activity questionnaire. A validated quantified food frequency questionnaire was administered by the investigator. Anthropometric measurements including weight, height and waist circumference were performed by the investigator. RESULTS: The study documented a high prevalence of obesity among female (45%) and male (32%) employees. A total energy intake above the Estimated Energy Requirement (EER) was found in 38% of males and 64% of female subjects. Fourty eight percent of males and 64% of female subjects exceeded the Acceptable Macronutrient Distribution Rate (AMDR) for total fat intake, while the mean saturated fatty acid (SFA) intake was above the recommendation of less than 10% of total energy intake. An inadequate fibre intake was observed for 87% of males and 55% of female subjects. Folate intakes below the Estimated Average Requirement (EAR) were found in 62% male and 82% of female subjects. A “low active” physical activity level (PAL) was found in 91% of females and 67% of professionals. Significantly more females (p=0.01) and professionals (p=0.00005) demonstrated a “low active” PAL compared to males and other occupational categories. Work-related barriers to a healthy lifestyle such as long working hours, work demands, a long commute and working shifts contributed to skipping of meals and prevention of physical activity participation among employees. CONCLUSION: The study demonstrated a high prevalence of overweight and obesity among employees characterised by high fat and inadequate fibre intakes, increasing the risk for CDL. Work-related barriers contributed to an unhealthy lifestyle and specific interventions at the workplace would appear necessary to decrease the high prevalence of obesity and risk for CDL. RECOMMENDATIONS: Wellness interventions should be introduced at DB-VM to improve the health and well-being of employees.
