Determinants of smoking among adolescents in the Southern Cape-Karoo region, South Africa.
ABSTRACT Tobacco control programmes in multi-ethnic societies must take into account ethnic differences in the determinants of smoking. The I-Change Model, an extension of the Theory of Planned Behaviour, was used to investigate the factors related to smoking among a sample of 3378 Black African, Coloured and White, monthly and non-monthly smokers in the Southern Cape-Karoo Region, South Africa. Across the ethnic groups, non-monthly smokers reported a more positive attitude towards non-smoking, social influences that were more supportive of non-smoking, higher self-efficacy in stressful, routine and social situations, greater intention not to smoke in the next year and lower levels of depressive mood and risk behaviour. Regression analyses suggested that the weight of these determinants may differ in predicting monthly smoking among the ethnic groups. Black African students may benefit from the development of attitudinal cognitions and coping skills to counter peer influence. Coloured students also require skills to resist peer influence. White students require coping skills in stressful and social situations. Although there are more common than unique determinants of smoking among South African adolescents, further research is needed to understand the influence of differing social, economic and cultural contexts on smoking onset.

ABSTRACT: From the Theory of Planed Behaviour (TPB), the aim of this study is to analyse the effect of self-efficacy and perceived control on intention and preventive behaviors of cardiovascular disease. To this end, 359 participants were evaluated in an empirical study. Data were analysed using the statistical package EQS 6.1. The results indicate that self-efficacy has a positive and significant influence on behaviour intentions and on behaviour, while perception of control has a negative and significant influence on intention but not on behaviour. This work has shown the utility to distinguish between self-efficacy and perceived control in the TPB to prevent cardiovascular diseases.Universitas Psychologica 05/2010; 9(2):423-432. · 0.40 Impact Factor

ABSTRACT: Tobacco smoking (i.e. cigarettes, rolled tobacco, pipes, etc.) is associated with significant health risks, reduced life expectancy and negative personal and societal economic impact. Smokers have an increased risk of cancer (i.e. lung, throat, bladder), chronic obstructive pulmonary disease (COPD), tuberculosis and cardiovascular disease (i.e. stroke, heart attack). Smoking affects unborn babies, children and others exposed to second hand smoke. Stopping or 'quitting' is not easy. Nicotine is highly addictive and smoking is frequently associated with social activities (e.g. drinking, eating) or psychological factors (e.g. work pressure, concerns about body weight, anxiety or depressed mood). The benefits of quitting, however, are almost immediate, with a rapid lowering of blood pressure and heart rate, improved taste and smell, and a longer-term reduction in risk of cancer, heart attack and COPD. Successful quitting requires attention to both the factors surrounding why an individual smokes (e.g. stress, depression, habit, etc.) and the symptoms associated with nicotine withdrawal. Many smokers are not ready or willing to quit and require frequent motivational input outlining the benefits that would accrue. In addition to an evaluation of nicotine dependence, co-existent medical or psychiatric conditions and barriers to quitting should be identified. A tailored approach encompassing psychological and social support, in addition to appropriate medication to reduce nicotine withdrawal, is likely to provide the best chance of success. Relapse is not uncommon and reasons for failure should be addressed in a positive manner and further attempts initiated when the individual is ready.Key steps in smoking cessation include: (i) identifying all smokers, alerting them to the harms of smoking and benefits of quitting; (ii) assessing readiness to initiate an attempt to quit; (iii) assessing the physical and psychological dependence to nicotine and smoking; (iv) determining the best combination of counselling/support and pharmacological therapy; (v) setting a quit date and provide suitable resources and support; (vi) frequent follow-up as often as possible via text/telephone or in person; (vii) monitoring for side-effects, relapse and on-going cessation; and (viii) if relapse occurs, providing the necessary support and encourage a further attempt when appropriate.South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde 11/2013; 103(11):869-76.
