Abstract: Objective: The author aimed to develop a valid and reliable questionnaire that would measure the knowledge of learners relating to risk factors for chronic disease of lifestyle such as stroke, diabetes and hypertension. The questionnaire was intended to be used as part of a health education programme aimed at improving the knowledge of learners as it relates to risk factors for chronic diseases of lifestyle. Method: The development of the questionnaire was guided by Williams 9 steps of questionnaire design and was influenced by the national curriculum of education’s life orientation programme and literature. A 31 item questionnaire was designed and presented to an expert panel. Content validity was done by the expert panel and face validity was tested through informal discussions with high school learners. Reliability testing was done using the test-retest method and Kappa co-efficient was used to test stability of the items. The questionnaire was administered to 40 high school learners but only 30 did the test the second time. Results: The questionnaire yielded a reliability analysis that revealed internal consistency with a Cronbach’s alpha of 0.897. The average score obtained by learners using this questionnaire was 14. The questionnaire can be used for learners with a grade 10 education. The questionnaire also highlighted that learners had a moderate knowledge relating to risk factors for chronic diseases of lifestyle and the need for appropriate information interventions was emphasized URI: http://hdl.handle.net/10566/115 Files in this item: 1

Abstract: This study aimed to determine the physical activity levels and existence of risk factors associated with chronic diseases of lifestyle among high school learners. A crosssectional research design was used to obtain information about physical activity levels from 951 learners from two high schools in a local community in the Western Province of South Africa. Physical activity levels were obtained using the KUOPIO Ischaemic Heart Disease 24-hour physical activity record over a seven-day period. Anthropometrical and blood pressure measurements as well as behaviours including cigarette smoking and alcohol use were recorded as risk factors for chronic diseases of lifestyle. Statistical analyses were performed using the Statistical Package for Social Science (2000). Risk factors were identified as obesity, physical inactivity, smoking and hypertension. Variance of analysis (ANOVA) was used to statistically determine differences in groups. The results indicated that 32% of the learners were classified as being physically inactive and that 21% engaged in health risk behaviours. In addition, 35% of the learners had more than one risk factor for chronic diseases of lifestyle present. Since cardiovascular risk factors have been shown to persist into adulthood, health professionals should assume some responsibility for the prevention, detection, and intervention relevant to cardiovascular risk factors in adolescents.

Abstract: Background: Intimate partner violence (IPV) is very high in Africa. However, information obtained from the increasing number of African studies on IPV among pregnant women has not been scientifically analyzed. This paper presents a systematic review summing up the evidence from African studies on IPV prevalence and risk factors among pregnant women. Methods: A key-word defined search of various electronic databases, specific journals and reference lists on IPV prevalence and risk factors during pregnancy resulted in 19 peer-reviewed journal articles which matched our inclusion criteria. Quantitative articles about pregnant women from Africa published in English between 2000 and 2010 were reviewed. At least two reviewers assessed each paper for quality and content. We conducted meta-analysis of prevalence data and reported odds ratios of risk factors. Results: The prevalence of IPV during pregnancy ranges from 2% to 57% (n = 13 studies) with meta-analysis yielding an overall prevalence of 15.23% (95% CI: 14.38 to 16.08%). After adjustment for known confounders, five studies retained significant associations between HIV and IPV during pregnancy (OR1.48–3.10). Five studies demonstrated strong evidence that a history of violence is significantly associated with IPV in pregnancy and alcohol abuse by a partner also increases a woman’s chances of being abused during pregnancy (OR 2.89–11.60). Other risk factors include risky sexual behaviours, low socioeconomic status and young age. Conclusion: The prevalence of IPV among pregnant women in Africa is one of the highest reported globally. The major risk factors included HIV infection, history of violence and alcohol and drug use. This evidence points to the importance of further research to both better understand IPV during pregnancy and feed into interventions in reproductive health services to prevent and minimize the impact of such violence.
