While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Pulmonary functions of commercial tricyclists (Keke Napep riders) in Enugu State, Nigeria
Abstract
Background: Tricyclists are continuously exposed to vehicle emissions and other environmental pollutants, due to the na- ture of their job and vehicle design, which may be hazardous to health. However, there is paucity of data on the pulmonary functions of commercial tricyclists in Nigeria, which should have provided insight into any relevant health concerns in this population, hence this study.
Objectives: This study evaluated the pulmonary functions of tricyclists, in comparison with those of age-matched non-tri- cyclists.
Methods: Two hundred and ten (210) [150 commercial tricyclists; 60 non-tricyclists] males (aged 20-65years) participated in this unmatched case-control study in Enugu, Enugu state, Nigeria. Their pulmonary functions [Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), Peak Expiratory Flow Rate (PEFR)] were assessed using a computerized spirometer. Independent T-test and Pearson Chi-square were used to analyze data at a significant level of P<0.05.
Results: Cough (46.0%) and dust allergies (40.7%) were the commonest reported respiratory symptoms among tricyclists. There were significant differences in the FVC (P<0.001), FEV1 (P<0.001) and PEFR (P<0.001) between the two groups, with tricyclists showing lower pulmonary function values. FEV1/FVC was <70% with increased FVC in 83.3% of the tricy- clists, suggesting restrictive pulmonary abnormalities.
Conclusion: Decreased pulmonary function values of commercial tricyclists in this study is suggestive of their predisposi- tion to occupation-related pulmonary disorders, particularly the restrictive patterns.
Keywords: Tricyclists; Keke Napep riders; pulmonary functionss; Nigeria.
