This study determined actual and perceived risk of Diabetes Mellitus (DM) among undergraduates in Osogbo in Southwestern Nigeria. It was a descriptive cross sectional explorative study conducted among 250 newly admitted undergraduates of Osun state University selected using multi-staged sampling method. Data on perceived and actual risk to DM were collected using pre tested self- administered semi-structured questionnaire. Data was analyzed using the SPSS software. Mean age of respondents was 21.0 2.4 years. Of the 250 students 230(92.0%) have heard about DM, 37(14.8%) were overweight and 9(3.6%) were obese. Only 11(4.4%) felt they were at risk of DM, 237(94.8%) said they were not at risk, 225(90.0%) said they can never have DM. Based on the six selected risk factors, only 64(25.6%) were at no risk, 137(54.8%) had single while 49(19.6%) were at multiple risk of DM. Of the 237 who claimed or perceived they were not at risk, only 64 (27.0%) were actually at no risk. A statistically significant relationship was found between actual DM risk and having heard about DM (p<0.05). Having heard about DM was the major predictor of congruent actual and perceived risk among studied respondents. It was concluded that incongruence between perceived and actual risk to DM exists among University undergraduates studied, an indication to step up awareness programmes about DM

Objective:To determine the larval habitats of mosquito fauna and possible impact of land use/land cover changes on the epidemiology of mosquito-borne diseases in Osogbo metropolis, Southwestern, Nigeria.
Methods: All accessible larval habitats were surveyed between May and September, 2011 in Osogbo metropolis while Land Use/ Land cover of the city was analyzed using 2 Lansat Multispectral Scanner satellite imagery of SPOT 1986 and LANDSAT TM 2009.
Results:A total of six species namely, Aedes aegypti, Aedes albopictus, Aedes vittatus, Anopheles gambiae complex, Culex quinquefasciatus and Eretmapodite chrysogaster were encountered during the study. The occurrence and contribution of disused tyres was significantly higher (P<0.05) than the other habitats encountered, while there were no significant differences in the contribution of gutters/run-offs, septic tanks/drums, ground pools/open drains and discarded containers to the breeding of mosquitoes (P>0.05). The accessible land use/land covered of the study area between 1986 and 2009 showed that the wet land coverage and settlement area increased from 0.19 to 9.09 hectare and 1.00 to 2.01 hectare respectively while the forest area decreased from 60.18 to 50.14 hectare.
Conclusion: The contribution of the habitats coupled with the increasing rate of flooded environment which could provide ample breeding sites for mosquitoes call for sustained environmental sanitation and management in Osogbo metropolis.
