Background: Welders are exposed to a variety of occupational hazards with untoward health effects. However, little is known of welders' awareness of health hazards and their adherence to safety precautions in developing countries. This study assessed the awareness of occupational hazards and adherence to safety measures among welders in Kaduna metropolis in northern Nigeria. Methods: A structured questionnaire was administered on a cross-section of 330 welders in Kaduna metropolis in northern Nigeria. Information was sought on their socio-demographic characteristics, their awareness of occupational hazards and adherence to safety measures. Results: All welders were males with a mean age of 35.7 ± 8.4 years. The illiteracy rate was 7.6%. Overall, 257 (77.9%) of the welders were aware of one or more workplace hazards. This was positively influenced by educational attainment, age, nature of training and work experience. Of the 330 respondents, 282 (85.3%) had experienced one or more work-related accidents in the preceding year. The most common injuries sustained were cut/injuries to the hands and fingers (38.0%), back/waist pain (19%), arc eye injuries/foreign bodies (17.0%), burns (14.0%), hearing impairment (7.0%), fractures (4.0%) and amputation (1.0%). Only 113 (34.2%) welders used one or more types of protective device with eye goggles (60.9%), hand gloves (50.3%) and boots (34.5%) being more frequently used. Regular use of safety device, shorter working hours and increasing experience were protective of occupational accidents. Conclusions:The level of awareness of occupational hazards was high with sub optimal utilization of protective measures against the hazards. There is therefore need for health and safety education of these workers for health and increased productivity.

BackgroundThe HIV/AIDS epidemic has been accompanied by a severe epidemic of tuberculosis (TB), although the prevalence of coinfection is largely unknown, especially in developing countries, including Nigeria. The aim of this study was to determine the prevalence and predictors of TB coinfection among HIV-seropositive Nigerians.MethodsThe case files of HIV/AIDS patients attending Aminu Kano Teaching Hospital, Nigeria from January to December 2006 were reviewed.ResultsA total of 1320 HIV/AIDS patients had complete records and were reviewed, among which 138 (10.5%) were coinfected with TB (95% CI, 8.9% to 12.2%). Pulmonary TB was diagnosed in 103 (74.6%) patients, among whom only 18 (17.5%) were sputum-positive. Fifty (36.2%) coinfected patients had some type of extrapulmonary TB (EPTB); 15 had both pulmonary TB and EPTB. Among the 35 patients with EPTB only, 20 (57.1%) had abdominal TB, 5 (14.3%) had TB adenitis, 5 (14.3%) had spinal TB, 3 (8.6%) were being monitored for tuberculous meningitis, and 1 (2.9%) each had renal TB and tuberculous adrenalitis. The highest prevalence of TB, 13.7% (n = 28), was seen among patients aged 41–50 years. TB coinfection was significantly associated with marital status, WHO clinical stage, and CD4 count. Marital status (OR, 2.1; 95% CI, 1.28–3.59; P = 0.04), WHO clinical stage at presentation (4.81; 1.42–8.34; P = 0.001), and baseline CD4 count (2.71; 1.51–6.21; P = 0.02) remained significant predictors after adjustment for confounding.ConclusionsThe moderately high prevalence of TB among HIV-seropositive patients underscores the urgent need for strategies that lead to rapid identification and treatment of coinfection with active or latent TB.

Women of childbearing age in a rural community in Kano state were interviewed to ascertain the determinants of utilization of antenatal care services in the village. Of the 200 women studied, 118 (59%) utilized antenatal care services during pregnancy. A majority (86%) of those who attained secondary school education, all of those with post-secondary education and 83% of those whose husbands had post-secondary education utilized antenatal care services.
