Cigarettes and social differentiation in France: is tobacco use increasingly concentrated among the poor?

ADDICTION, Issue 10 2009
Patrick Peretti-Watel
ABSTRACT Aims This paper aimed to assess whether the increase of social differentiation of smoking is observed in France. Design and setting Five cross-sectional telephone surveys conducted in France between 2000 and 2007. Participants The surveys were conducted among national representative samples of French subjects aged 18,75 years (n = 12 256, n = 2906, n = 27 499, n = 2887, n = 6007 in 2000, 2003, 2005, 2006 and 2007, respectively). We focused on three groups: executives, manual workers and the unemployed. Measurements Time trends of smoking prevalence were assessed, and socio-economic factors (especially occupation and job status) associated with smoking were identified and compared in 2000 and 2005. We also computed respondents' equivalized household consumption (EHI) and their cigarette budget to assess the financial burden of smoking. Findings Between 2000 and 2007, smoking prevalence decreased by 22% among executive managers and professionals and by 11% among manual workers, and did not decrease among the unemployed. Indicators of an underprivileged social situation were associated more markedly with smoking in 2005 than in 2000. In addition, the falling-off of smoking initiation occurred later and was less marked among manual workers than it was among executive managers and professionals. Finally, in 2005 15% of French smokers devoted at least 20% of their EHI to the purchase of cigarettes, versus only 5% in 2000, and smoking weighted increasingly heavily on the poorest smokers' budgets. Conclusions While these results point out an increased social differentiation in tobacco use, they underline the need to design and implement other forms of action to encourage people to quit, in particular targeting individuals belonging to underprivileged groups.

How do trends in smoking prevalence among Indigenous and non-Indigenous Australian secondary students between 1996 and 2005 compare?

Abstract Objective: To compare trends in smoking prevalence between 1996 and 2005 among Indigenous and non-Indigenous secondary students across Australia. Methods: Representative random samples of secondary students aged 12-17 years completed self-report anonymous surveys. Questionnaires assessed any cigarette smoking in lifetime, and smoking in past month, week and on at least three of the previous seven days. Intention to smoke in the next 12 months was assessed on a 7-point scale. Students self-identified as being of Aboriginal or Torres Strait Islander descent. Results: Three to four per cent of students identified as being Indigenous at each survey. Smoking was more common among Indigenous than non-Indigenous students. Between 1996 and 2005, the proportion of smoking declined among both Indigenous and non-Indigenous students. However, among 12-15 year olds, the rate of decline was different for the two groups. Among non-Indigenous students in this age group, prevalence decreased steadily between 1996 and 2005. Among Indigenous students, the decrease mainly occurred between 1999 and 2002. Smoking intention was higher for Indigenous than non-Indigenous students. The mean intention decreased between 1996 and 2005 among both student groups. Conclusions: Smoking prevalence decreased among both Indigenous and non-Indigenous students between 1996 and 2005. Implications: Reductions in Indigenous students' tobacco use and intentions coincided with a period of increased tobacco control activity, suggesting that these activities may positively influence smoking behaviours.

The changing panorama of cerebral palsy in Sweden.

ACTA PAEDIATRICA, Issue 9 2010

Abstract Aim:, The aim of the study was to describe the prevalence and origin of cerebral palsy (CP), which is the tenth report from the western Swedish study. Methods:, A population-based study covering 85 737 live births in the area in 1999,2002. Birth characteristics and neuroimaging findings were recorded, prevalence of CP was calculated and aetiology was analysed. Results:, CP was found in 186 children. The crude prevalence was 2.18 per 1000 live births. The gestational age-specific prevalence for <28 gestational weeks was 55.6 per 1000 live births, whereas it was 43.7 for 28,31 weeks, 6.1 for 32,36 weeks and 1.43 per 1000 for >36 weeks. There was a female majority among children born at term and a male predominance in children born preterm. Hemiplegia accounted for 38%, diplegia for 32%, tetraplegia for 7%, whereas 17% had dyskinetic CP and 5% ataxia. Neuroimaging showed white-matter lesions in 31% and cortical/subcortical lesions in 29%. The aetiology was considered to be prenatal in 36%, peri/neonatal in 42%, whereas it remained unclassified in 21%. Conclusion:, The decrease in CP prevalence observed since the 1980s had ceased. An increase in children born at term and in dyskinetic CP was found. In children born before 28 weeks of gestation, the prevalence decreased significantly. White-matter and cortical/subcortical lesions dominated on neuroimaging. [source]
