In Nigeria, commercial motorcycle
popularly referred to as ‘Okada’ has helped many people over come traffic
delays, maneuver bad non-motorable routes, enjoy fresh air while mobile and
other things. But in what seemed like a means of enjoyment and one of the preferred
mean of transportation in Nigeria, experts in the medical have spelt out some
of the danger associated with okada riding.
Tribune newspaper says more…
In this part of the world where our
transportation system leaves much to be desired, motorcycles, commonly called
okada, are a necessary evil. This is not unconnected with the fact that they
are a quick means of transport, they are efficient in mitigating traffic jams
which most cities are renowned for, they get to areas which are ordinarily
unmotorable and they are available throughout day and night hours. Since their
introduction into the country and use for commercial purposes, they have
continued to increase exponentially and based on this, the cases of motorcycle
accidents have equally skyrocketed.
A visit to the Accident and
Emergency wards of hospitals, especially teaching hospitals, in cities where
okadas are still in operation, would attest to the fact that the occupational
risk of this group of people should indeed be a source of concern.
According to Dr Ademola Ajibade, a
medical practitioner, “motorcycle injuries are among the leading causes of
disability and deaths and the main victims are the motorcyclists, passengers
and pedestrians in their young reproductive age group. In fact, motorcycle
accidents are far more likely than other vehicular accidents. Motorcycle riders
are the most vulnerable groups of road users.”
The reason for this may not be
far-fetched. Motorcyclists, especially the young ones, tend to speed too much
and overload their motorcycles for quick returns and they are usually reckless,
undisciplined and have a lack of respect for other road users. Dr Ajibade adds
that the majority of them don’t wear any protective gear, including helmets and
this aggravates the risks of getting severe head injuries and even death in the
event of an accident.
Saturday Tribune findings revealed
that some of the reasons for non-compliance with the use of protective gear and
the practice of safe road use among motorcycle riders included ignorance of the
importance of the use of protective gear, a general disposition towards
lawlessness, lack of education on proper road use and traffic laws, the cost of
the gears as well as the abuse of drugs and use of alcohol.
Besides the obvious risk of
accidents which motorcycle riders and their passengers are exposed to, there
are other concerns that they should make conscious efforts to consider in order
to enjoy optimal health at their occupation.
One health hazard associated with
okada riding, especially for long periods at a time, is the exposure to
pollutants, especially from their motorcycles and other vehicles on the road.
According to experts, motorcycle riders are exposed to pollutants such as
nitrogen oxides, carbon monoxide, sulfur dioxide, volatile organic compounds
and particulate matter in ambient air, and these may affect lung function. It
has been discovered that the inhalation of these automobile pollutants can
cause respiratory problems.
Moreover, extreme vibrations due to
the performance of the motorcycle engine, improper structural design of the
motorcycle (evident in the type of seating and type of suspension), bad road
conditions, age of the motorcycle are also potential sources of health
problems. Experts state that the human body can tolerate certain levels of
vibrational energy but starts to deteriorate and cause long-term damage and
disruption of the natural processes of the body at other levels of vibration.
These vibrations are transmitted to the buttocks and back along the vertical
axis via the base and back of the seat. On the other hand, the pedals and
handle transmit additional vibrations to the feet and hands of the rider.
During motorcycle riding, due to its unbalancing nature, it creates enormous
vibration and affects the bioelectric phenomena.
A study of “Vibration and its
effect on health of the motorcycle rider” published in the April-June 2010
edition of Online Journal of Health and Allied Sciences pointed out that at
varying frequencies of vibrations, certain health effects can occur ranging
from motion sickness, chest and abdominal pain, backache, intestine and bladder
problems to degradation in visual functions. These vibrations are in the form
of Hand Arm Vibrations and Whole Body Vibrations. Health effects that
associated with Whole Body Vibration and especially the driving environment
have been discovered to include piles, high blood pressure, kidney disorders
and impotence.
Where vehicles provide protection
against harsh weather conditions through the presence of windscreens, okadas
lack such and as a result, their riders are exposed to extreme weather “They
ride in the scorching sun, windy weather and sometimes even in the rain and
most times, without the proper protective clothing. Protective gear do not stop
at helmets. They also include high-visibility vests, boots, gloves. Not only
are helmets supposed to protect the head in the case of accidents, they are
also there to protect the face from the wind, flying objects and insects which
could enter the eyes, nose or ears,” Dr Ajibade said.
Also importantly is the increased
risk of reproductive problems. A Japanese study of 234 avid motorcyclists
between the ages of 20 and 60 found significantly higher Erectile Dysfunction
(ED) across all age ranges compared to a control group. Among bikers aged 50 to
59, 93 per cent had ED, compared to 42 per cent of the controls. A subsequent study
of 150 Japanese motorcyclists by the same authors also found that not only was
the rate of ED more than three times greater among motorcyclists than the
control group, but there was a clear link between their ED and other lower
urinary tract disorders.
The likeliest culprit was constant vibration from both
the engine and the road.
Physical strain is also an issue to
grapple with. “The physical strain can cause problems with joints such as knees
and wrists. When riding a motorcycle, the body position constricts regular
blood flow to the feet, ankles and knees, depending on the type of bike design.
This is why you sometimes notice swelling on the feet of okada riders who drive
for long periods. Appropriate compression socks can help to improve leg circulation,
lowering swelling while riding,” Dr. Irene Bassey, general practitioner at
Orbitals Clinic, Lagos State, said.
Though they have been banned in some
states, they still pose a significant health and safety risk in places where
they are operational and moreso, where there is no insistent on the use of
protective gear. According to Mr. Temiloluwa Gbarada, a health, safety and
environment professional, “Whenever one is on an okada, the miracle is that one
arrives at his place of destination in one piece. From a safety perspective,
okadas, by default, are an accident waiting to happen. In risk assessment
safety standards, riding or being a passenger on an okada is way above the
acceptable risk limit because it’s not balanced, there is no protective covering
(like a windscreen) and because of their size, they are most often ignored by
other vehicle users. If at all, it has to be used, then personal protective
equipment like helmets and full body protective clothing (padded) should be
worn.”
