Health effects of noise exposure levels among instrumentalists in pentecostal churches in port harcourt city, Nigeria

BACKGROUND: Noise is everywhere in our daily lives and becomes very important as it affects our health. Religion is anintegr al part of daily lives and the use of acoustic and electronic instruments in worship. With the increase in sophistry of these instruments come their attendant untoward effects on the auditory organs of the body. This study was to assess noise exposure levels amongst instrumentalists in Pentecostal churches in Port Harcourt City, Nigeria.MATERIALS & METHODS: Following ethical consideration, 216 consenting respondents from 30 churches in Port Harcourt were recruited by table of random numbers. Structured close ended interviewer administered questionnaire incorporating the Hearing Health Quick Test (HHQT) was used to access demographic data. Hearing assessments were also performed using tonal audiometry. The data were entered and analyzed using SPSS version 20.0 and presented using descriptive and inferential statistics.RESULTS: Most 90.28% and 37.96% of respondents were male and within the 39-45 year-old age range respectively. Also, 80.56% of respondents were aware that loud music can cause permanent hearing loss. The prevalence of NIHL andTinnitus was 39% and 38% respectively; and only 19% used Hearing Protection Devices (HPD). Statistically significant risk of NIHL was observed in musicians who had experienced tinnitus, played only amplified instruments and Music experience greater or equal to 10 years (p=0.001).CONCLUSION: Gospel instrumentalists are exposed to noise in the course of their duties which have significant effect on their hearing. Use of Hearing Protection Devices (HPD) as a personal protective equipment is encouraged just as health education of this group of workers is necessary

Current State of Public Cemeteries in River State; Nigeria

Cemeteries or 'sleeping places' are where bodies or cremated remains are buried. Dead bodies are essentially 'wastes' and their improper disposal in the form of burial may come with health implications. This is particularly apt in Nigeria and indeed Rivers State where unsupervised burials are carried out in homes (houses); compounds and community-based cemeteries. A walk through survey of five functional public cemeteries in Rivers State appraised their current state and their possible health implications. This on-the-spot site visit revealed infrastructural; operational and maintenance challenges which have further stressed the need for better managed public cemeteries and more objective studies on the subject

Recent Change of locality as Risk Factor for Malaria Fever among New Residents of Ahoada East Local Government Area in Southern Nigeria

Relocation which is a well-known determinant of malaria in non-immune travelers to malarious areas; has also been found to be a risk factor for malaria among semi-immune persons who change locality within endemic regions. Further research evidence suggests that the higher transmission intensity at the travel location is an underlying factor which may indicate exposure to new variants of P falciparum for which specific immunity is lacking. This study was conducted to determine if recent change of locality increased the risk of malaria fever among semi-immune National Youth Service Corps members serving in a district in southern Nigeria.Method: Ninety six corps members who had just been posted to Ahoada-East LGA in southern Nigeria and 83 others that had been in service for six months; were followed up for malaria fever in a prospective cohort design over a 3 month period from September 2010 to December 2010. Active surveillance was used to obtain reports of fever among the cohort; followed by medical examination at designated local health facilities.Results: No significant differences in age and use of protection against malaria were found between the study groups. The incidence proportion of malaria for the recently relocated group (34) was significantly higher than that of the resident group (15.7). Recent change of locality was more associated with malaria fever (RR 2.19; 95 CI 1.243.88; AR 54.4).Conclusion: The recent change of locality within an endemic region; which serves as an indicator of exposure to new variants of P falciparum; for which specific immunity is lacking; is a significant risk factor for malaria fever. Protection against malaria is recommended for semi-immune individuals moving to new locations with significant risk of malaria transmission

Evaluation of Peak Expiratory Flow rates (PEFR) of Workers in a Cerment Factory in Port Harcout South-South; Nigeria

Occupational lung diseases (OLD) remain one of the most common workplace health challenges since the industrial revolution. One of the risks for OLD is the exposure to cement dust which is associated with varying degrees of respiratory symptoms and reduction in lung function. This study aimed to measure the peak expiratory flow rates (PEFR) of workers in a cement manufacturing company in Port Harcourt and estimate the determinants of the measured rates.Method: In this descriptive cross-sectional study; 105 workers of a cement company who presented for the annual fitness to work exercise were sampled and had their peak expiratory flow rates measured using a spirometer. Data were also collected using structured interviewer-administered questionnaires and a walk through survey carried out to examine workplace situation. The results were analyzed using descriptive and inferential statistics.Results: The study showed that 13.3 of the workers had abnormal (i.e low) PEFR. The lowest mean PEFR of 327.5L/min was found among workers who had worked for 21 23 years and worked mainly at the production and bagging area. Most of the workers (81.9) made effective use of some form of personal protective equipment (PPE).Conclusion: Reduction in the PEFR implied that prolonged exposure to cement dust may result in decreased lung function and by extension pulmonary disease. The high percentage of normal PEFR found among the workers; irrespective of their duration of work; could be attributed to the effective use of the PPE
