    Studies show that the health risks posed by dumpsites are significant especially when the area used for dumping is easily accessible. Children, the immunocompromised, the mentally challenged individuals are specifically vulnerable to the physical, ecological and chemical dangers posed by wastes. This study sought to assess the knowledge, attitude and perceptions of the residents of Kadhodeki village on the health risks posed by the Kadhodeki dumpsite. Using households as units of sampling, a descriptive cross sectional survey was carried out in June 2012. Random data were collected using a face-to face researcher administered structured questionnaire where 323 participants were interviewed. Chi square was used to determine the association between the different variables. Findings indicate that residents posses a significantly low knowledge and a positive attitude (χ2 (1) = 224.03, p < 0.01; χ2 (1) = 8.697, p < 0.01).There were however no differences in risk perceptions. Participant’s age, duration one had lived in the village and their level of education, were proxy measures of knowledge, attitude and perception. Odds ratio analysis indicates that age and duration did not influence participant’s knowledge, attitude or perceptions. However, education accounted for a non significant 28% variation in respondents’ attitude towards the health risks of the dumpsite (OR= 1.282; CI 0.828- 1.997). Adequate education on the other hand significantly accounted for 67% variation in respondents’ health risk perception (OR= 1.671; CI 1.304-2.140). From the findings of this study, the ministry of Health is recommended to come up with health education programmes for the general population on the dangers of uncontrolled waste disposal sites.

Rudimentary however, education accounted for a non significant 28% variation in respondents’ attitude towards the health risks of the dumpsite (OR= 1.282; CI 0.828- 1.997). Also adequate education significantly accounted for 67% variation in respondents’ health risk perception (OR= 1.671; CI 1.304-2.140). This study would recommend that the ministry of Health come up with health education programmes for the general population on the dangers of uncontrolled waste disposal sites.

    Prevalence, Knowledge, Attitude and Practice of Speeding in Two Districts in Kenya: Thika and Naivasha.
    (Elsevier Ltd, 2013) Nyamari, J. M.; Bachani, A. M.; Hung, Y. W.; Mogere, S.; Akungah, Daniel Nyagetiria; Stevens, K. A.; Hyder, A. A.
    INTRODUCTION: In Kenya, RTIs had the second highest increase in disability-adjusted life years between 1990 and 2010, compared to other conditions. This study aims to determine the prevalence, knowledge, attitudes and practices for speeding in Thika and Naivasha districts in Kenya. METHODS: Direct observations of vehicle speed were conducted at various times during the day and different days of the week on six roads selected based on a multi-stage sampling method in two districts to determine the prevalence of speeding. Roadside KAP interviews were administered to drivers, at motorcycle bays, petrol stations, and rest areas. RESULTS: Eight rounds of speed observations and four rounds of KAP interviews were conducted between July 2010 and November 2012. Results from the speeding observational studies show an overall high proportion of vehicles speeding above posted limits in both districts, with an average of 46.8% in Thika and 40.2% in Naivasha. Trend analysis revealed a greater decline in this prevalence in Thika (OR: 0.804, 95% CI: 0.793-0.814) than in Naivasha (OR: 0.932, 95% CI: 0.919-0.945) over the study period. On average, 58.8% of speeding vehicles in Thika and 57.2% of speeding vehicles in Naivasha travelled at 10 km/h or higher above speed limit. While the majority of respondents agreed that speeding is a cause of road traffic crashes in both Thika (70.3%) and Naivasha (68.7%), knowledge of speed limits at the location of the interview was limited. Enforcement levels also remained low, but subsequent rounds of data collection showed improvement, especially in Thika. CONCLUSIONS: This study demonstrates an improvement in the prevalence of speeding in two districts of Kenya over 2010-2012. It also highlights the need for further action to be taken to address the problem, and represents new data on speeding in Kenya and Africa.
