A roadside alcohol prevalence survey of drivers randomly selected from
the general traffic was conducted in Eldoret, Kenya, Blood alcohol co
ncentration (BAC) data obtained by a breath test in 90% of the sample
(n=479) was analysed by demographic and travel characteristics. 19.9%
had a positive breath test (BAC greater than or equal to 5 mg%), 8.4%
had BACs greater than 50 mg%, and 4% exceeded 80 mg%, A greater propor
tion of males (20%) had been drinking compared to females (12.5%): all
drivers with high BACs (greater than or equal to 50 mg%) were males.
The likelihood of having consumed alcohol was greater in motorists age
d 25 years and above (20.4%) than in younger drivers aged 16-24 years
(15.4%), their mean BACs were also more elevated (57 mg% versus 31 mg%
), In comparison to operators of public service vehicles (PSV), people
driving personal cars were more than twice as likely to have been dri
nking: with 21.9% being BAC positive against 10.8% (OR=2.3; 95% CI, 1.
0 to 6.3, p=0.05), Educated individuals with skilled careers tended to
indulge in drink-driving to a greater extent than professional driver
s (operators of public transport, taxi and heavy goods vehicles), with
BAC prevalence rates of 23.7% and 15.5%, respectively. Other circumst
ances influencing the probability of drink-driving were number of vehi
cle occupants, distance to destination, road location, time of the nig
ht and whether it was a weekend or weekday. These findings are discuss
ed in relation to the potential for promotion of relevant deterrent me
asures, including the establishment of an appropriate BAC legal limit
for drivers in Kenya.
