Background: Psychoactive substance use was common among commercial motorcycle operators. Studies had shown that there were some socio-demographic factors which were commoner among commercial motorcycle operators who used psychoactive substances. However, this was not explored among commercial motorcycle operators in Kano, North Western Nigeria. Aim: The aim of the study was to determine the socio-demographic factors associated with psychoactive substance use among motorcycle operators in Kano, Northwestern Nigeria. Methods: It was a cross-sectional study. Instrument used for data collection included socio-demographic questionnaire and World Health Organisation Student Drug Use Questionnaire. Data analysis was done using Statistical Package for Social Sciences (SPSS) 16th edition. Results: Commercial motorcycle operators who used substances were found to be of younger age group (X 2 = 10.9, P < 0.001), single (X 2 = 4.3, P = 0.034) and had a father who used tobacco (X 2 = 4.28, P = 0.04). Participants who were single were more likely to use inhalants (X 2 = 21.06, P = 0.001), opiates (X 2 = 11.82, P = 0.012), cannabis (X 2 = 5.12, P = 0.028) and stimulants (X 2 = 5.12, P = 0.028) compared to those who were married. Conclusion: This study found that being of younger age, being single, and having a father who smoked were significantly associated with psychoactive substance use. Participants who were singles were more likely to use inhalants, opiates, cannabis and stimulants. No relationship was observed between the age of the respondents and specific substance use. Legislations should be enacted to reduce the rate of psychoactive substance use among motorcycle operators and general population at large.

Introduction:Sleep is an integral part of human physiology; therefore, disorders of sleep may result in significant derangement in human functionality. Sleep medicine has received little attention in Nigeria. Against this backdrop, this survey seeks to evaluate the quality of sleep among doctors.Methodology:This was a cross-sectional descriptive study involving 59 doctors working with Federal Medical Centre Birnin Kebbi, Kebbi State, Nigeria; it was done between August 2017 and December 2017. Purposive sampling method was adopted. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were adopted. The questionnaire was self-administered.Results:There were 34 (57.6%) males and 25 (42.4%) females. Their age ranged from 20 to 66 years, with a mean of 34.39 ± 8.00. The Epworth score ranged from 8 to 29, with a mean of 16.1 ± 4.4, while the PSQI score ranged from 5 to 19, with a mean of 9.5 ± 2.7. The mean work hour per week was 90.3 ± 36.2 h, and majority of the respondents worked for >80 h and or >24 h consecutively in the preceding week, and most had high ESS scores; however, this observation was not statistically significant (Fisher's exact test = 4.0904, P = 0.213). All respondents were poor sleepers and majority sleep for <7 h in the night. Respondents had worked for 5 years and less; house officers and medical offers had more tendencies for daytime sleepiness.Conclusion:All respondents were poor sleepers and also had prolonged work hours per week; there was also heightened daytime sleepiness.

The present study was carried out in the most populated city in Northern Nigeria that is believed to have the highest number of commercial motorcyclists and highest prevalence of psychoactive substance use in the country. Research on psychoactive substance use among motorcycle operators in Northern Nigeria is limited, despite the high level of morbidity these substances cause to them. This study aimed to study the prevalence of psychoactive substance use among motorcycle operators in Kano, North western Nigeria. The study was cross-sectional descriptive. Participants for the study were commercial motorcyclists registered with the local branch of Amalgamated Commercial Motorcycle Owner's and Riders Association of Nigeria (ACOMORAN). Assessment was carried out with the use of socio-demographic questionnaire and World Health Organization Student Drug Use Questionnaire (SDUQ). Data obtained was analysed using Statistical Package for Social Sciences (SPSS), 17 th edition. Three hundred and ninety four (394) subjects participated in the study. The results showed that the prevalence of overall psychoactive substance use was 19.3%. The prevalence of tobacco, stimulant (gadagi), and cannabis use were 19.3, 11.9 and 3.8% respectively, while the prevalence of inhalants and opiates use were 2.0 and 1.3%, respectively. There were no reported use of alcohol, benzodiazepines and cocaine. All the subjects were males, Moslems, within the age range of 22 and 60 years mean of 32.7 ± 6.6 years. They were mostly married (88.6%), and more than two third of them (70.1%) were from Kano. The study has highlighted the prevalence of substance use among commercial motorcyclists. It has important implication for policy makers to initiate primary preventive measures that could be focused towards the reduction of substance use among commercial motorcyclists in the community.
