Adolescent smoking and depression: evidence for self-medication and peer smoking mediation

ADDICTION, Issue 10 2009
Janet Audrain-McGovern
ABSTRACT Aims The nature of the relationship between adolescent smoking and depression is unclear and the mechanisms that account for the comorbidity have received little investigation. The present study sought to clarify the temporal precedence for smoking and depression and to determine whether these variables are linked indirectly through peer smoking. Participants The sample was composed of 1093 adolescents participating in a longitudinal study of the behavioral predictors of smoking adoption. Design and measurements In this prospective cohort study, smoking, depression, peer smoking and other covariates were measured annually from mid-adolescence (9th grade; age 14) to late adolescence (12th grade, age 18). Findings Parallel processes latent growth curve models supported a bidirectional relationship between adolescent smoking and depression, where higher depression symptoms in mid-adolescence (age 14) predicted adolescent smoking progression from mid- to late adolescence (ages 14,18). A significant indirect effect indicated that higher depression symptoms across time predicted an increase in the number of smoking peers, which in turn predicted smoking progression from mid-adolescence to late adolescence. In addition, smoking progression predicted a deceleration of depression symptoms from mid- to late adolescence. A significant indirect effect indicated that greater smoking at baseline predicted a deceleration in the number of smoking peers across time, which predicted a deceleration in depression symptoms from mid-adolescence to late adolescence. Conclusions The current study provides the first evidence of bidirectional self-medication processes in the relationship between adolescent smoking and depression and highlights peer smoking as one explanation for the comorbidity.

Childhood social disadvantage and smoking in adulthood: results of a 25-year longitudinal study

ADDICTION, Issue 3 2007

ABSTRACT Aim To examine the associations between exposure to socio-economic disadvantage in childhood and smoking in adulthood. Design A 25-year longitudinal study of the health, development and adjustment of a birth cohort of 1265 New Zealand children. Measurements Assessments of childhood socio-economic disadvantage, smoking in adulthood and potential mediating pathways, including: parental education, family socio-economic status, family living standards and family income; smoking frequency and nicotine dependence at age 25 years; child IQ, educational achievement by age 18 years, conduct problems ages 14,16 years, parental smoking 0,16 years and peer smoking at 16 years. Findings Smoking at age 25 was correlated significantly (P < 0.0001) with increasing childhood socio-economic disadvantage. Further, indicators of childhood socio-economic disadvantage were correlated significantly (P < 0.0001) with the intervening variables of childhood intelligence, school achievement, conduct problems and exposure to parental and peer smoking; which in turn were correlated significantly (P < 0.0001) with measures of smoking at age 25. Structural equation modelling suggested that the linkages between the latent factor of childhood disadvantage and later smoking were explained largely by a series of pathways involving cognitive/educational factors, adolescent behavioural adjustment and exposure to parental and peer smoking. Conclusions The current study suggested that smoking in adulthood is influenced by childhood socio-economic disadvantage via the mediating pathways of cognitive/educational factors, adolescent behaviour and parental and peer smoking.

Perceived peer smoking prevalence and its association with smoking behaviours and intentions in Hong Kong Chinese adolescents

ADDICTION, Issue 9 2004

ABSTRACT Background Among the many personal, social and environmental risk factors of adolescence smoking, normative beliefs stand out for their potential to be modified with factual information on smoking prevalence. Aims To study the perceived peer smoking prevalence and its association with smoking behaviours in Hong Kong Chinese adolescents. Design and setting Cross-sectional territorial-wide school-based survey conducted in 64 randomly selected secondary schools in Hong Kong. Participants A total of 13 280 forms 1,3 students (equivalent to grades 7,9 in the United States) aged 12,16 years. Measurements Perceived peer smoking prevalence, smoking status, intention to smoke in future, other smoking-related factors and demographic information. Findings Overestimation of peer smoking prevalence was observed regardless of gender and smoking status, and was more common in girls (69.4%) than boys (61.0%), and in experimental (74.3%) and current smokers (85.4%) than in never smokers (60.7%). Boys who overestimated and grossly overestimated (over two times) peer smoking were more likely to be current smokers, with adjusted odds ratios and 95% confidence intervals (95% CI) of 1.95 (1.24,3.07) and 3.52 (2.37,5.24) (P for trend <0.001). Similarly, boys who grossly overestimated peer smoking were 76% (95% CI: 41,120%) more likely to have ever smoked. Conclusion Overestimation of peer smoking prevalence was common in Hong Kong Chinese boys and girls, and was associated with current and ever smoking in boys. These findings have important implications on normative education in adolescence smoking prevention programmes. [source]


Correlates of smoking among adolescents with asthma

JOURNAL OF CLINICAL NURSING, Issue 5-6 2010

Aims and objective., This study examined the correlates of smoking among asthmatic adolescents to gain a better understanding of who is at particular risk. Background., Smoking is especially harmful to individuals with asthma. However, smoking is surprisingly prevalent among asthmatic individuals, with prevalence rates similar to or higher than those of the general adult or adolescent populations. Despite this notable finding, there has been little research about factors (i.e. biophysical, psychosocial and behavioural) influencing asthmatic adolescents' tobacco use patterns. Design., A Canadian provincial cross-sectional survey. Method., The study about adolescents' tobacco use and health status was conducted in secondary schools in 2004, 608 asthmatic adolescents participated. Demographic factors, biophysical (body mass index and physical health), psychosocial factors (parents' and peers' smoking, environmental tobacco smoke exposure and depression) and behavioural factors (marijuana use, alcohol use and exercise frequency) were explored. Multinomial logistic regression analyses were conducted to identify risk factors associated with tobacco use. Results and conclusions., Of the 608 asthmatic adolescents, 17·4% currently smoked and 12·0% formerly smoked. Girls, compared with boys, were more likely to smoke (OR: 3·34, 95% CI: 1·62,6·96) after adjusting for differences in the other demographic, biophysical, psychosocial and behavioural factors. Asthmatic girls who had relatively higher body mass index, were in the higher school grades, used marijuana or alcohol, had minor to severe depressive symptoms, had environmental tobacco smoke exposure in their homes and had friends who smoked or were currently more likely to smoke. The former smokers had similar risk factors including higher body mass index, environmental tobacco smoke exposure at home, friends who smoked and marijuana use. Relevance to clinical practice., Despite their health condition, asthmatic adolescents continue currently or formerly to smoke. Gender appropriate prevention and cessation interventions for asthmatic adolescents may need to address important psychosocial and environmental factors that increase the risk of these adolescents initiating and maintaining tobacco use.
