Time trends of socioeconomic inequalities in adolescent smoking in Okinawa, Japan, 2008-2016: a repeated cross-sectional study

BACKGROUND@#Smoking among Japanese adolescents has decreased noticeably. However, little is known whether the decreasing trend in adolescent smoking can be seen across all socioeconomic status (SES) groups. This study aimed to examine trends in socioeconomic inequalities in smoking among Japanese adolescents between 2008 and 2016.@*METHODS@#We conducted a repeated cross-sectional study using data from three surveys of high school students in Okinawa, Japan, in 2008, 2012, and 2016. The study participants consisted of 7902 students in grades 10 through 12 (15-18 years). Smoking was assessed as current cigarette use. SES indicators included familial SES (parental education and family structure) and student's own SES (school type). To evaluate absolute and relative inequalities, prevalence differences (PDs) and ratios (PRs) between low and high SES groups were estimated. The slope index of inequality (SII) and relative index of inequality (RII) were also calculated.@*RESULTS@#Smoking prevalence among boys and girls significantly declined from 11.5% and 6.2% in 2008 to 4.7% and 1.9% in 2016, respectively. Similar decreasing trends in smoking were found among most of the SES groups. The PDs and SII for parental education in boys and family structure in girls decreased over time while those for school type persisted among boys and girls. The PRs and RII for school type in boys increased while those for other SES indicators among both sexes remained stable over time.@*CONCLUSIONS@#Smoking among Japanese adolescents has been declining and time trends of socioeconomic inequalities in smoking varied by absolute and relative measures. Further policies and/or interventions to reduce smoking inequalities should focus on the context of schools, especially in vocational high schools.

Insatisfacción corporal, creencias sobre control del peso y consumo de cigarrillos en jóvenes / Body dissatisfaction, beliefs about weight control, and cigarette use among youth

En diversos estudios los investigadores han encontrado una relación entre insatisfacción corporal, creencias de control de peso asociadas al consumo de cigarrillos y el consumo de cigarrillos en jóvenes. Este estudio evaluó un modelo de mediación de las creencias de control de peso asociadas al consumo de cigarrillos en la relación entre insatisfacción corporal y consumo de cigarrillos. Se realizó un estudio correlacional con 651 jóvenes chilenos de entre 12 y 23 años de edad. Se realizaron ANOVA y análisis de regresión lineal para evaluar las hipótesis propuestas. Se encontró una relación entre insatisfacción corporal y consumo de cigarrillos y diferencias significativas en dicha relación según sexo. Los resultados obtenidos confirman la relación entre insatisfacción corporal y consumo de cigarrillos en jóvenes chilenos, sin embargo, no se comprueba la mediación propuesta.

In several studies, researchers have found a link between body dissatisfaction, weight control beliefs associated with cigarette use and cigarette smoking among young people. This study examined a mediation model of weight control beliefs associated with cigarette use for the relationship between body dissatisfaction and cigarette smoking. A correlational study was conducted with 651 young chileans between 12 and 23 years of age. ANOVA and linear regression analyses were conducted to evaluate the proposed hypotheses. A relationship between body dissatisfaction and smoking and significant differences by sex for this relationship were found. These results confirm the relationship between body dissatisfaction and cigarette smoking among young Chileans, however, do not support the proposed mediation.

Effects of Self-Hand Massage with Aroma Oil on Daily Cigarette Use, Smoking Craving and Depression of Female High School Student Smokers / 여성건강간호학회지

PURPOSE: The purpose was to test the effects of self-hand massage with aroma oil on daily cigarette use, smoking craving, and depression of female high school student smokers who are attempting to quit smoking. METHOD: A convenience sampling of a non-equivalent control group time series was used. Female high school student smokers were assigned either to smoking cessation lecture only or to an intervention that involved a smoking cessation lecture and self-hand massage with aroma oil for 4 weeks. Lavender, Peppermint, and Bergamotte essence oils were used for massage. RESULT: There was a significant change in daily cigarette use and depression between the groups at three different times. CONCLUSION: It is promising that self-hand massage with aroma oil can be an effective adjunctive to decrease daily cigarette use and depression of female high school student smokers who are attempting to quit smoking.
