A study was carried out in 18 locations in the Nandi North, Nandi South and Nandi Hills districts of Kenya, which cover the Nandi Hills and Nandi Forests in Nandi County, major water catchments for Lake Victoria. A mixed methodological approach, incorporating both qualitative and quantitative data obtained from focus group discussions, key informant interviews, household survey and observations was embraced in data collection and analysis. The study reveals that there are several strategies that have been adopted by the local population and institutions involved in the management of the Nandi Hills Forests （NHFs） and that these strategies have contributed to an improvement in the perceptions of the local population in terms of the importance of environmental management of the forests. This paper highlights EE as a vehicle for ensur- ing a sustainable management of the Nandi Hills Forests. As such, it illuminates the great potential that lies in sustainably managing the NHFs by integrating formal and informal EE approaches. It further points out the functional gaps in the management of NHFs and proposes best-practices that could be adopted and/or domesticated in NHFs management regimes.展开更多

A total of 250 purposively selected regular female athletes from five Nigerian universities （two federal universities, two state universities and one private university）, in the south-East Geopolitical zone of the country. A self structured questionnaire with reliability value of 0.73. The test-retest method was used for data collection. Data collected were subjected to descriptive statistics of frequency, percentage and Chi-square inferential statistics at 0.05 level of significance. Findings revealed that majority perceived FGM as harmful and detrimental to excellent sports performance, administration and management. Based on the result of the study, it was therefore recommended that government should design programmes aimed at improving the education of the girl-child as this has been identified as one of the factors which will help to change the attitude of mothers towards the practice of FGM.展开更多

Some with TB disease are unaware of their HIV status, yet HIV/TB coinfection is high. The study aims to determine the prevalence of TB among older adults with HIV, their HIV/AIDS knowledge and vulnerability to hypertension, diabetes and asthma using the 2013 BAIS IV data. Material and Methods: The BAIS IV study, from which the data for this article is derived, used a stratified two-stage probability sampling design. The first stage was the selection of 297 Enumeration Areas (EAs) as Primary Sampling Units and second stage was selection of households (5,415) in the EAs. The study targeted all usual members of the selected households aged 6 weeks and above for the Biomarker or testing for HIV and those aged 10 - 64 years old for the behavioral questionnaire. Results: The study shows that the older adults (50 - 64 years) with TB have a low level of education and HIV prevalence is very high (44% for age 50 - 54, 40.6% for age 55 - 59 and 68.4% for age 60 - 64 years). The rate of HIV/TB coinfection, 21.9%, is high and prevalence of TB among the older adults is 8.6% (13%, males and 5.3%, females) while only 0.8% are currently on treatment. Only 67.2% know that if a pregnant mother is infected with HIV, there is a way of preventing transmission of the virus to the child. Age, level of education, marital status and employment status significantly (p Conclusion: The study concludes that lower education seems to be an obstacle to accessing TB treatment. Therefore, older adults’ awareness and knowledge of the symptoms of both diseases (TB and HIV), mode of infection and treatment need to adequately improve through increased education to overcome health challenges when infected with asthma, diabetes and high blood pressure/hypertension.展开更多
