Aim: To evaluate the association between selected potential socio-demographic and behavioral risk factors and infertility in Nigerian men. Methods: There were two groups in this study. One group consisted of 150 men with proven male infertility, and the other consisted of 150 fertile men with normal semen parameters. Both were matched for age, place of residence and key socio-demographic variables. They were compared for sexual history, past medical and surgical history, past exposures to sexually transmitted infections and treatment, past and current use of drugs as well as smoking and alcohol intake history. Results: Infertile men were significantly more likely than fertile men to report having experienced penile discharge, painful micturition and genital ulcers, less likely to seek treatment for these symptoms and more likely to seek treatment with informal sector providers. Multivariate analysis showed that male infertility was significantly associated with bacteria in semen cultures, self-reporting of previous use of traditional medications and moderate to heavy alcohol intake, but not with smoking and occupational types. Conclusion: Infertility is associated with various proxies of sexually transmitted infections (STIs) and poor healthcare-seeking behavior for STIs in Nigerian men. 相似文献

We conducted a cohort study on impact of effects of eight years of annual ivermectin mass treatment administered in eight villages in Imo State, Nigeria. Physical and visual acuity examinations carried out in 462 persons in 1995, prior to the launching of mass drug administration with ivermectin, were compared with re-examinations of 411 (89%) of these same individuals in 2002. We found that gross visual impairment decreased from 16% to 1%, nodule prevalence decreased from 59% to 18%, and papular dermatitis was reduced from 15% to 2%. No change was seen in leopard skin rates (14%). The only incident lesions were three subjects from a single community having the appearance of new nodules (e.g., nodules not identified in the 1995 examinations). Differences in community coverage did not appear to influence the benefit from treatment of individual residents. 相似文献

We conducted a population survey with the objective of identifying the level of cancer awareness. In Nigeria many patients present late for medical care. We analysed data from 460 literate Nigerians. Three hundred and sixty (78.3%) had heard about cancer. 34.1% identified particular risk age categories, while 62.2% said that cancer could occur at any time. Awareness of warning signs and sites of cancer location was very poor and only 33% recognized that a breast lump was a warning sign. Knowledge of methods of early detection was also very low and only 50% said that cancer is curable when detected early. This investigative survey highlighted a considerable ignorance and lack of awareness of cancer among the Nigerian population. 相似文献

The human resources crisis in Africa is especially acute in the public health field. Through distance education, the School
of Public Health of the University of the Western Cape, South Africa, has provided access to master's level public health
education for health professionals from more than 20 African countries while they remain in post. Since 2000, interest has
increased overwhelmingly to a point where four times more applications are received than can be accommodated. This home-grown
programme remains sensitive to the needs of the target learners while engaging them in high-quality learning applied in their
own work contexts. 相似文献

OBJECTIVE: A survey of Salmonella contamination of poultry droppings used as manure, retail fresh beef, fresh beef retailers' aprons and fresh beef retail tables, was carried out. DESIGN: A total of 120 samples of poultry droppings collected from five poultry farms, 96 fresh beef samples, 96 beef retailers' aprons and 96 fresh beef retail tables were examined for the presence of Salmonella species. RESULTS: Different Salmonella serotypes were isolated from all the sources. Salmonella paratypi A had an isolation rate of 12.5% from poultry droppings, 4.2% from fresh beef, and 2.1% and 4.2% from meat retailers' aprons and tables respectively. Other serotypes isolated from the sources included S. typhimurium, S. enteritidis, S. gallinarum, S. pullorum, S. typhi and S. agama. Salmonella typhi was not isolated from poultry droppings throughout the survey. CONCLUSION: There is a need to create more environmental and personal hygiene awareness among the Nigerian populace, especially among food vendors. 相似文献
