Equity impact of population-level interventions and policies to reduce smoking in adults: a systematic review

BACKGROUND AND AIMS

There is strong evidence about which tobacco control policies reduce smoking. However, their equity impact is uncertain. The aim was to assess the effectiveness of population-level interventions/policies to reduce socioeconomic inequalities in adult smoking.

METHODS

Systematic review of studies of population-level interventions/policies reporting smoking-related outcomes in adults of lower compared to higher socioeconomic status (SES). References were screened and independently checked. Studies were quality assessed. Results are presented in a narrative synthesis. Equity impact was assessed as: positive (reduced inequality), neutral (no difference by SES), negative (increased inequality), mixed (equity impact varied) or unclear.

RESULTS

117 studies of 130 interventions/policies were included: smokefree (44); price/tax (27); mass media campaigns (30); advertising controls (9); cessation support (9); settings-based interventions (7); multiple policies (4). The distribution of equity effects was: 33 positive, 36 neutral, 38 negative, 6 mixed, 17 unclear. Most neutral equity studies benefited all SES groups. Fourteen price/tax studies were equity positive. Voluntary, regional and partial smokefree policies were more likely to be equity negative than national, comprehensive smokefree policies. Mass media campaigns had inconsistent equity effects. Cigarette marketing controls were equity positive or neutral. Targeted national smoking cessation services can be equity positive by achieving higher reach among low SES, compensating for lower quit rates.

CONCLUSIONS

Few studies have assessed the equity impact of tobacco control policy/interventions. Price/tax increases had the most consistent positive equity impact. More research is needed to strengthen the evidence-base for reducing smoking inequalities and to develop effective equity-orientated tobacco control strategies.

Maintaining abstinence from cigarette smoking: effectiveness of group counselling and factors predicting outcome

The aim of the study was to assess the effectiveness of worksite group counselling interventions designed to prevent smoking relapse after abstinence has been achieved following 3 months therapy using group support and/or transdermal nicotine replacement therapy. After 3 months, abstinent subjects were randomly allocated either to a counselling group led by professional psychologists (PG), to a counselling group led by former smokers (SG) or to no intervention group (NG). The 3 and 12 months abstinence were defined, respectively, as a sustained smoking cessation during the last month, and the last 9 months. Complete abstinence was confirmed by expired carbon monoxide and by urine cotinine concentrations. The abstinence rate at 3 months was 35.1%. After 12 months abstinence rates were not statistically different in the PG, the SG and the NG (respectively 57.8, 53.4 and 49.6% of those randomised). In multivariate analyzes, baseline variables associated with 12 months abstinence were non-smoking family, gender (male), lower daily intake of nicotine and better psychological adjustment. Mean weight gain at 3 months in abstinent versus relapsed subjects, was respectively, 4.1 and 2.4 kg. Baseline variables associated with weight gain at 3 months were higher Fagerström score, gender (male) and professional status (blue collar worker). Group support after abstinence has been achieved did not significantly improve the abstinence. This study shows the difficulty of preventing smoking relapse with monthly group counselling. The results indicate the need to investigate further specific programmes focusing on factors such as gender, family, nicotine dependence, psychological and weight concerns/issues which may precipitate relapse.
