Objective: To evaluate the knowledge and practices of smoking cessation among physicians in Nigeria. Methods: We conducted a cross-sectional survey in Lagos and three geopolitical zones of Nigeria. A self-administered structured questionnaire was used to obtain information on tobacco use and its health effects, as well as on the knowledge and practices of smoking cessation, from 436 physicians. Results: Of the 436 physicians, 292 (67.0%) were aware of smoking cessation, but only 132 (30.3%) showed good knowledge on this topic. The prevalence of smoking among the physicians was 17.7%. In addition, 308 physicians (70.6%) reported that tobacco education in the medical school curriculum was inadequate. Of the 436 physicians, 372 (86.2%) asked their patients whether they smoked, and 172 (39.4%) asked their patients the reasons for using tobacco. As a means of smoking cessation intervention, 268 (61.5%) used brief advice/counseling (2-5 min), 12 (3.7%) prescribed antidepressants, 16 (2.8%) prescribed nicotine replacement therapy (NRT), and 76 (17.4%) arranged follow-up visits. When the physicians were questioned regarding the obstacles to smoking cessation interventions, 289 (66.3%) cited poor knowledge of the issue, 55 (12.6%) cited a lack of time, and 20 (4.6%) cited unavailability of NRT. Conclusions: The results of this study highlight the lack of knowledge among physicians in Nigeria in terms of smoking cessation, as well as their failure to apply appropriate practices. The results of this study can further the evaluation and formulation of guidelines on smoking cessation and smoking education programs for physicians. Our findings also underscore the need to offer smoking cessation programs in all treatment facilities.

Objective: The aim of this study was to determine the factors associated with nocturnal, productive and dry cough among young adults in Nigeria. Methods: We evaluated 498 subjects, 20-44 years of age, in Ilorin, Nigeria, using the European Community Respiratory Health Survey (ECRHS) questionnaire, administered by trained interviewers. Results: Nocturnal cough was associated with asthma (OR = 10.87; p < 0.01), nasal allergy (OR = 6.33; p < 0.01), smoking (OR = 3.10; p < 0.01), skilled manual and non-manual work (OR = 2.86 and 2.10, respectively; p < 0.01 for both) and female gender (OR = 1.33; p = 0.17). Productive cough was associated with skilled manual and non-manual work (OR = 3.82 and 3.03, respectively; p < 0.01 for both), smoking (OR = 3.10; p < 0.01), asthma (OR = 3.27; p < 0.01) and nasal allergy (OR = 5.81; p < 0.01). Dry cough was associated with asthma (OR =5.18; p < 0.01) obesity (OR =1.88; p = 0.19), smoking (OR = 1.77; p = 1.44), nasal allergy (OR = 1.45; p = 0.26) and female gender (OR =1.36; p = 0.33). Age, gender, type of residence and obesity were not significantly associated with any type of cough (p > 0.05). Conclusions: Early prevention and treatment of conditions associated with cough, as well as the modification of social factors commonly associated with cough, are needed in order to reduce respiratory morbidity.

Objective: To determine whether respiratory symptoms and chronic bronchitis are associated with the use of biomass fuels (BMFs) among women residing in rural areas of the Ekiti State, in southwestern Nigeria. Methods: From January to June of 2009, we carried out a cross-sectional study including 269 adult women. To collect data on sociodemographic status, type of fuel used for cooking in the household, respiratory symptoms, and smoking history, we used a questionnaire adapted from the European Community Respiratory Health Survey. All of the participants were invited to undergo spirometry. Results: Of the 269 women in the study, 161 (59.9%) used BMFs for cooking. The proportion of women who reported respiratory symptoms was greater among those using BMFs than among those using a non-BMF-cough (13.7% vs. 3.7%); wheezing (8.7% vs. 2.8%); chest pain (7.5% vs. 1.9%); breathlessness (11.8% vs. 6.5%); nasal symptoms (9.3% vs. 4.6%); and chronic bronchitis (10.6% vs. 2.8%). Multivariate logistic regression analysis revealed that the use of BMFs was associated with the following variables: cough (OR = 4.82; p = 0.01); chronic bronchitis (OR = 3.75; p = 0.04); wheezing (OR = 2.22; p = 0.23); chest pain (OR = 3.82; p = 0.09); breathlessness (OR = 1.54; p = 0.35); and nasal symptoms (OR = 2.32; p = 0.20). All of the spirometric parameters evaluated (FEV1, FVC, FEV1/FVC ratio, and PEF) were lower in the women using BMFs than in those using a non-BMF. Conclusions: Our results underscore the need for women using BMFs in their households to replace them with a nontoxic type of fuel, such as electricity or gas.
