title: Factors associated with nocturnal, productive and dry cough in the young adult population of Nigeria.
abstract: 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.
