CHAPTER ONE
INTRODUCTION
- Background to the Study
The impact of smoking and tobacco use on health
cannot be over emphasized. Cigarette smoking remains a gigantic public health
problem and is still regarded as one of the leading preventable causes of
morbidity and mortality worldwide (Can, Topbas, Ozuna, Ozgun, Can &
Yavuzyilmaz, 2009; Mpabulungi & Muula, 2004; Salawu, Danburam, Desalu,
Olokoba, Agbo & Midala, 2009;World health Organisation, 2015). It is
well-known that many smokers start before the age of 18 years, however, it is
of great interest to know that the increasing trend in smoking prevalence
amongst youths and the likelihood that many of these young people who begin to
smoke at an early age, will continue to do so throughout adulthood (Adebiyi,
Faseru, Sangowawa & Owoaje, 2010).
Although tobacco use has declined in many high
income countries such as the United States and United Kingdom, it is increasing
in many low and middle income countries (Boutayeb & Boutayeb, 2005; Warren,
Jones, Eriksen & Asma, 2006) and in current situation, tobacco smoking is
by far the most popular form of smoking and is practiced by over one billion
people in the majority of all human societies (Akinpelu, 2015). Tobacco is the
most common hazardous substance and this is aided by its legally availability,
heavy promotion and wide consumption and has been revealed to be problematic
including other forms of use other than cigarettes, which is on the rise among
adolescents in many countries, and is likely to jeopardize progress in reducing
chronic diseases and tobacco-related mortality (CDC, 2010; Warren et al., 2006).
The constant increase in the consumption of tobacco
among adolescents is emerging as a complex and multidimensional problem (Soni
& Raut, 2012). Melgosa (2006) rightly considers tobacco as a drug with the
lowest risk, in the short term but one which takes away health and life from
the greatest number of people in the long term.
Cigarette smoking is said to be responsible for over
25 diseases in humans some of which include: ischemic heart disease, chronic
bronchitis and cancers of the lung, oral cavity, urinary bladder, pancreas, and
larynx (Desalu, Olokoba, Danburam, Salawu & Issa, 2008). Over the past four
decades, tobacco use has caused an estimated 12 million deaths in the world,
including 4.1 million deaths from cancer, 5.5 million deaths from cardiovascular
diseases, 2.1 million deaths from respiratory diseases and 94,000 infant deaths
related to mothers smoking during pregnancy (WHO, 2009; Centers for Disease
Control and Prevention, 2002; Ekrakene & Igeleke, 2010) and on average
cigarette smokers lose about 15 years of their life (The global tobacco survey
collaborative group, 2002; Raji, Abubakar, Oche & Kaoje, 2013).
It is estimated that number of deaths due to tobacco
will increase from 3 million per year worldwide to 70 million per year by 2025
(Reddy & Arora, 2005; US Department of Health and Human Services, 2012). It
has been said that adolescents are especially vulnerable to these effects and
may be more likely than adults to develop an addiction to tobacco (Chakraborty,
2009). In addition, it has been predicted that if the pattern currently seen
among youth continues, a lifetime of tobacco use would result in the deaths of
250 million children and young people alive today, most of them in developing
countries (WHO, 2012).
Like other developing countries, the most
susceptible age for initiating tobacco has been found between the ages of 15-24
years as evident in the study by Gboyega, Adesegun and
Chikezie (2013) identifying
youths as a major group involved in smoking over the last two decades,an age group where most are expected to be in
school. Educational attainment is widely regarded as an important health risk
factor because of how strongly it has been associated with health outcomes,
health-related behaviors, and other risk factors (National Center for Health
Statistics, 1999). For the past 30 years, smoking prevention programmes have
been focused almost exclusively upon youth, mainly within the school setting
(Backinger, 2003;Ekanem, 2008; Salawu, Danburam & Isa, 2010; Fawibe &
Shittu, 2011; Hammond, 2005; Nwafor, Ibe & Aguwa, 2012; Odukoya, Odeyemi
& Oyeyemi, 2013; Okagua, Opara & Alex-Hart, 2015) despite School
dropouts being more likely to smoke heavily than students (Aloise-Young,
Cruickshank & Chavez, 2002). In Nigeria, the prevalence of tobacco use
among youth tends to be higher than among adults (Odukoya, Odeyemi, Oyeyemi
& Updhyay, 2013).
- Statement of the Problem
Smoking among youths has been on an increase worldwide (Pomara, Cassano, D’Errico, Bello, Romano & Riezzo et al, 2012) with values ranging from 721 million in 1980 to 967 million in 2012 (Marie, 2013). Studies have revealed that there has been a high increase in the prevalence rate of smoking among youth in sub-Saharan Africa(Shafey, Dolwick & Guindon, 2012) and Nigeria precisely (Drope, 2011; Yahya, Hammangabdo & Omotara, 2010), with statistics showing that youths form over 40% of the Nigerian population and 18% of the youths smoke, identifying youths as a major group involved in smoking over the last two decades (Gboyega, Adesegun & Chikezie, 2013).
Smokers’ low perception of the negative effects of their smoking behavior on their health also results in many of them being unwilling to quit smoking with most of them expressing a sense of invincibility to the hazards of smoking (Fawibe & Shittu, 2011). Studies have shown that individuals who perceive fewer risks and greater benefits of smoking are more susceptible to initiation (Song, Morrell, Cornell, Ramos, Biehl, Kropp & Halpern-Felsher, 2009).Literatures have shown that perceptions about health risks influence cigarette smoking among youths (Aryal, Petzold & Krettek, 2013; Mantler, 2013).Further studies havealso shown that each day, more than 3,200 people under 18 smoke their first cigarette, and approximately 2,100 youth and young adults become daily smokers.
Furthermore, studies have indicated
that as at 2012 it was noted that death as a result of non-communicable
diseases (respiratory tract infection inclusive), accounted for 2.7 million
deaths in sub-Saharan Africa with the inclusion of Nigeria as a result of
smoking (WHO, 2000-2012). Also literature has shown that nearly 9
out of 10 lung cancers are caused by smoking and smokers today are much more
likely to develop lung cancer than smokers were in 1964 (Siegel, Miller, Jemal,
2016). In Nigeria and worldwide
smoking causes many types of cancer, including cancers of the throat, mouth,
nasal cavity, esophagus, stomach, pancreas, kidney, bladder, and cervix, as
well as acute myeloid leukemia (Jha, Ramasundarahettige
& Landsman, 2013). Also
studies still shows that 8 out of 10 COPD (Chronic Obstructive Pulmonary
Disease) deaths are a result of smoking and currently, there is no cure for
COPD (Madu, Matla, 2014).
In spite of the passage of the National Tobacco Control Bill by the National Assembly in Nigeria, a bill aimed at domesticating WHO Framework Convention on Tobacco Control (FCTC) to avert the unimaginable disaster associated with smoking many youth are still caught in the web of the act, thereby endangering their lives.It will therefore be of immense benefit to investigate patterns of smoking and health risk perception of out-of-school youths in selected motor parks in Oshodi local government area of Lagos state, Nigeria.
1.3 Objective of the Study
The general objective for this study is to assess
the pattern of smoking among out-of-school youth and their health risk
perception.
The specific objectives are to:
- measure the
level of smoking prevalence among respondents;
- assess the
pattern of smoking among respondents and
- determine if
respondents have a good health risk perception of smoking.
