The relationship between asthma control and health-related quality of life in asthma and the role of atopy: a cross-sectional study of Nigerian adult asthmatics.

Introduction: the relationship between asthma control and health-related quality of life (HRQoL) in adult asthmatics is fairly established, but the unique contribution of atopy to this relationship has received less attention. The aim of this study was to quantify the contribution of atopy to this relationship.

Methods: in a cross-sectional study, we assessed HRQoL using mini-Asthma Quality of Life Questionnaire (AQLQ).

Domestic solid fuel combustion in an adult population in Nigeria: A cross sectional analysis of association with respiratory symptoms, quality of life and lung function.

Background And Objectives: We examined the association of respiratory symptoms, health status, and lung function with the use of solid fuel (wood, charcoal, coal or crop residue) for cooking or heating in a predominantly non-smoking population.

Methods: Using the protocol of the Burden of Obstructive Lung Diseases (BOLD) initiative, we collected representative population data using questionnaires and spirometry tests. We categorized solid fuel use into 'never user', 'ex user' and 'current user' based on responses to the survey.

Biomass smoke exposure as an occupational risk: cross-sectional study of respiratory health of women working as street cooks in Nigeria.

Objective: Little is known about respiratory health of women who are occupationally exposed to biomass smoke outside their homes. This study reports the exposure and respiratory health of street cooks in Ile-Ife, Nigeria.

Methods: We assessed exposure to biomass smoke by questionnaire in 188 street cooks and 197 control women and by personal diffusive samplers to quantify volatile organic compounds (VOCs) in a subsample of the women.

Reduced Forced Vital Capacity in an African Population. Prevalence and Risk Factors.

Rationale: Black Africans have reduced FVC compared with white persons, but the prevalence and determinants of reduced values are not well understood.

Objectives: To evaluate the prevalence and factors leading to reduced FVC in a Nigerian population and to examine current theories regarding the determinants of this difference.

Methods: We studied the ventilatory function of 883 adults aged 40 years or older participating in the Burden of Obstructive Lung Disease Study in Ile-Ife, Nigeria.

Chronic Airflow Obstruction in a Black African Population: Results of BOLD Study, Ile-Ife, Nigeria.

Global estimates suggest that Chronic Obstructive Pulmonary Disease (COPD) is emerging as a leading cause of death in developing countries but there are few spirometry-based general population data on its prevalence and risk factors in sub-Saharan Africa. We used the Burden of Obstructive Lung Disease (BOLD) protocol to select a representative sample of adults aged 40 years and above in Ile-Ife, Nigeria. All the participants underwent spirometry and provided information on smoking history, biomass and occupational exposures as well as diagnosed respiratory diseases and symptoms.

Asthma in a university campus: a survey of students and staff of Obafemi Awolowo University, Ile-Ife, Nigeria.

Background: Asthma continues to be an important cause of morbidity and mortality in developing countries. But, its burden among adult populations in university campuses is not well described.

Method: Through a multistage cluster sampling of students and staff of the Obafemi Awolowo University, Ile-Ife, Nigeria, we obtained a representative sample, each for students and staff.

Secondhand smoke exposure among nonsmoking adults in two Nigerian cities.

Background: Tobacco control policy can only succeed if the burdens of smoking are known. The objective of this study was to determine the prevalence and correlates of secondhand smoke (SHS) exposure among nonsmoking adults in two Nigerian cities.

Materials And Methods: We carried out a cross-sectional study from October 2009 to April 2010 among adult population of two Nigerian cities: Enugu and Ilorin.

Prevalence and patient characteristics associated with pleural tuberculosis in Nigeria.

Background: Tuberculosis is a leading cause of mortality worldwide, with a growing death rate. The pleural space is a common extrapulmonary site of involvement. The aim of this paper is to document prevalence and types of pleural involvement in pulmonary tuberculosis and patient characteristics associated with its occurrence.
