AbstractObjective: To further explore smoker views
on reasons to quit.
Methods: As part of the multi-country ITC
Project, a national sample of 1,376 New
Zealand adult (18+ years) smokers was
surveyed in 2007/08. This sample included
boosted sampling of Māori, Pacific and
Asian New Zealanders.
Results: ‘Setting an example to children’
was given as ‘very much’ a reason to quit
by 51%, compared to 45% giving personal
health concerns. However, the ‘very much’
and ‘somewhat’ responses (combined)
were greater for personal health (81%)
than ‘setting an example to children’ (74%).
Price was the third ranked reason (67%).
In a multivariate analysis, women were
significantly more likely to state that ‘setting
an example to children’ was ‘very much’ or
‘somewhat’ a reason to quit; as were Māori,
or Pacific compared to European; and
those suffering financial stress.
Conclusion: The relatively high
importance of ‘example to children’ as
a reason to quit is an unusual finding,
and may have arisen as a result of social
marketing campaigns encouraging
cessation to protect families in
New Zealand.
Implications: The policy implications could
include a need for a greater emphasis on
social reasons (e.g. ‘example to children’),
in pack warnings, and in social marketing
for smoking cessation.
Key words: quitting motives, smokers,
parents, children.

Smoking by parents, siblings and
friends has been recognised as
increasing the risk of smoking
uptake.1 Other research has associated
decreased public and private indoor smoking
with decreased risks of starting smoking.2,3
These effects of decreased smoking are
consistent with the body of theory about
the effect of social context on human
behaviour,4 and suggest that decreased
example reduces the risk of starting smoking
and increases quitting.
The attitudes of smokers towards setting
an example to children may have an impact
on quitting behaviour, attitudes towards
supporting smokefree areas (e.g. smokefree
playgrounds),5 and location of smoking
behaviour (e.g. smoking out-of-sight of
children). There is some evidence that one
of the reasons that smokers quit is so as to
set an example for children, although this
has not been a dominant motive.6-10 In a 1990
survey of San Francisco smokers, Latinos
were much more likely than whites to say
it was important to quit as an example for
children.7 A review of 35 studies conducted
before 2001 and that investigated reasons for
quitting, found that in nearly all the studies,
both smokers and ex-smokers put personal
health as the most important reason.6
However, one 2006/07 survey in France
found 60% of smokers gave the health effects
of secondhand smoke on non-smokers as a
reason to quit, 48% gave personal health,
62% the price of cigarettes, and 80% gave
setting an example to children.11
In this study we aimed to further explore
smoker views on: i) reasons to quit, and
ii) on quitting to set an ‘example to children’,
by socio-demographic and smoking-related
variables.
MethodsFor the New Zealand arm of the
International Tobacco Control Policy
Evaluation Survey (ITC Project), smokers
were recruited from the New Zealand Health
Survey (NZHS) sample of 2006/07.12 The
NZHS participants (age 18 and over) were
selected by a complex sample design, which
included systematic boosted sampling of
the Māori, Pacific and Asian populations.
Face-to-face interviews were conducted in
participants’ homes, with a response rate
was 67.9%, resulting in 11,924 interviews.
From the NZHS sample we took smokers
who: i) were 18 years or older; ii) had
smoked more than 100 cigarettes in their
lifetimes; iii) had smoked at least once in the
past 30 days; and iv) had agreed to be willing
to participate in further research when asked
this at the end of the NZHS interview (this
was 85.2% of the adult smokers in the
NZHS). Out of 2,438 potential respondents
who met these criteria, a total of 1,376
completed the NZ ITC Project Wave 1
questionnaire, giving a response rate of
56.4%. But when considering the NZHS
response rate and willingness to further
participate, then the overall response rate is
reduced further to 32.6% (for details see:13).
The computer-assisted telephone survey,
between March 2007 and February 2008,
was usually three to four months after the
NZHS interview. The study protocol was

cleared by the Multi-Region Ethics Committee in New Zealand
(MEC/06/07/071) and by the Office of Research Ethics, University
of Waterloo, Waterloo, Canada (ORE #13547).
We asked the 12 standard ITC Project questions on reasons to
quit (see Table 1). The results were weighted to reflect the national
population of smokers in New Zealand. The multivariate analysis
involved two models: a) using socio-demographic variables
(age, gender, ethnicity, socioeconomic deprivation, and financial
stress); and b) adding smoking-related beliefs and behaviours
(see a previous article using this dataset for more detail on
these models).14
ResultsOf the 12 reasons offered for wanting to quit, or staying quit,
‘setting an example to children’ received the highest level of
the ‘very much’ response (by 50.8%; 95%CI=47.2–54.3%) see
Table 1. Concern for personal health (44.7%, 95%CI=41.2 –
48.2%), the price of cigarettes (38.1%) and concern about effects
of cigarette smoke on non-smokers (33.5%) were the next most
important reasons. However, when the ‘very much’ and ‘somewhat’
responses were combined, concern for personal health (80.6%)
was higher than ‘setting an example to children’ (73.5%) and the
price of cigarettes (66.5%). A separate analysis by the total of the
‘very much’ responses for all respondents (n=3,679) also indicated
the statistically significant dominance of the ‘example to children’
response (20.8% versus 18.0% for ‘personal health’ and 15.3%
for price (data not shown but available on request).
In univariate analysis, the socio-demographic characteristics
of respondents, which were significantly associated with the
combined ‘very much’ or ‘somewhat’ responses for ‘setting an
example to children’ were: i) women compared to men (crude
odds ratio (OR)=1.64; 95%CI=1.18 – 2.28); ii) those of Māori and
Pacific ethnicity, compared to European (OR=1.51; 95%CI=1.05
– 2.18; OR=2.02; 95%CI=0.99 – 4.13 respectively); and iii) those
under one form of financial stress (i.e. not spending on household
essentials because of smoking, compared to those who said no to
this question (OR=1.61; 95%CI=1.05 – 2.46).
In the multivariate analysis, being a woman remained significant
(e.g. adjusted OR (aOR)=1.64; 95%CI=1.16 – 2.31 in the model
considering socio-demographic variables). Being Māori or Pacific
ethnicity and being under financial stress were still associated
with raised odds ratios (for all: aOR>1.2) but these were no
longer statistically significant. In the model that also considered
smoking beliefs and behaviours, the following were significantly
associated with concern about setting an example to children:

Notes:a) Depending on their quit status at the time of the survey, there were different questions asked, hence the variable values for number of respondents for some
of the questions. The introductory format of the various questions were as follows: “Even though you mentioned that you are not currently planning to quit, in the past 6 months, have each of the following things led you to think about quitting:…”; “In the past 6 months, have each of the following things led you to think about quitting:…”; “To what extent, if at all, were each of the following things, reasons for your current quit attempt:…”; “To what extent, if at all, have each of the following things helped you to stay quit:…”. For each question the responses offered were “not at all”, “somewhat”, or “very much”?
b) Paired matched odds ratio with exact McNemar significance probability for the change in “very much” for each variable relative to “very much” response for “Setting an example for children”.
c) At the time of the Wave 1 survey there were no pictorial warnings on NZ packs, but a text warning did state that smoking harmed others.

Smoking Prevention Smoker interest in setting an example to children
being a lighter smoker (using a ‘heaviness of smoking’ index:
aOR=1.11, 95%CI=1.01 – 1.22); awareness of secondhand smoke
(SHS) harm (aOR=1.62; 95%CI=1.20 – 2.17); and SHS protective
behaviours by smokers (aOR=1.81; 95%CI=1.40 – 2.35).
DiscussionThis study (along with the French survey, also from the ITC
Project), is unusual in finding ‘setting an example to children’
as being more important than smokers’ concern for health,
as a strong reason to quit or to stay quit. In the New Zealand
case, the importance of this reason was better captured by
allowing respondents to consider the ‘very much’ option in the
survey question.
The difference from most previous findings may also reflect
differences in the nature of the New Zealand smoker sample and
tobacco control policy context. For instance, there may have been
an influence from the spread of local authority smokefree parks
policies, which aim to discourage smoking around children.15
The review by McCaul et al, that found smokers and ex-smokers
putting personal health as the most important reason to quit, was
of studies that were nearly all were set in North America.6
An alternative view is that the data from the French ITC Project
and our study reflects trends that are occurring more widely. We
found no comparable data in other studies collected since 2001,
so further up-to-date evidence from other countries is needed to
investigate this issue.
Since 1998, there have been at least 15 media campaigns in
the US, particularly in California, Massachusetts and Colorado,
which have highlighted a smoker’s responsibility to quit smoking
for the sake of their family (see http://apps.nccd.cdc.gov/MCRC/
Apps/SearchResult.aspx?Mode=QS). New Zealand smokers of all
ethnicities may also have been sensitised to family responsibility
and smoking, because of social marketing over the past eight years
about quitting for family and whanau (extended family).16-18 The
social marketing has included media campaigns featuring ex-
smokers who highlight the effects of smoking on their families.
A previous smaller survey in New Zealand, in 1992, found social
reasons (socially unacceptable, family pressure) for quitting were
less important then, compared to personal health and cost.19 Other
research has indicated that ‘example to children’ as a quit motive
may increase over time.10
Quitting because of cost or financial stress is a common reason
given for quitting or the importance of quitting.6,20 Our results
indicate that this was the third ranked reason, and highlight
the importance of tobacco prices (via high tobacco taxes) in
stimulating quitting. Because there was no tobacco tax rise in New
Zealand between 2001 and 2008 (apart from annual indexation),
and tobacco products appear to have become more affordable in
this period,21 this may have decreased the perception of cost as a
reason to quit.
Ethnic differences in reasons to quit may be related to the
differing role of family and social structures and influences,
for ethnic groups. Perez-Stable et al. argue that famialismo
(family/collective well-being) may explain Latino/non-Latino
differences in reasons to quit.7 The greater likelihood of Māori
and Pacific peoples, in seeing the example of smoking to children
as a reason to quit, may be related to their greater priority on
collective relationships.22
Policy implicationsThe recognition by policymakers of the danger of smoker
examples to children has led to a widening of tobacco control
policy actions. These have included explicit warnings to smokers
of these effects from their smoking on cigarette packaging warning
labels,23 the extension of smokefree outdoor area policies,24 and
making schools completely smokefree. The policy implications
of our findings could include a need for a greater emphasis on
social reasons (e.g. ‘example to children’) in pack warnings, in
social marketing campaigns for smoking cessation, and in the
information around targeted smoking cessation support for new
parents and school teachers.
Research implicationsThe finding of ‘setting an example to children’ as a relatively
important reason to quit or to stay quit, should be explored in
other settings with the same questions, and also with different
approaches to collecting data (e.g. unprompted reasons for quitting
or staying quit). Data analysis by whether there are children in the
interviewee’s household would provide further depth. Gender,25
and ethnic differences in quitting motivation (as opposed to
behaviour), may also be an area for further exploration, considering
the limited research in the area and the importance of addressing
disparities in smoking prevalence. Survey findings such as these
may also be further explained and explored by qualitative research,
in order to provide a more in-depth understanding of smokers’
attitudes and reasons for quitting.
