Legislative smoking bans for reducing secondhand smoke exposure ...

Cesaroni 2008 (Continued)
Outcomes Smoking prevalence as measured by self-reported smoking status. Age-standardised rates of acute coronary events
annually, stratified prior to analysis by age categories 35-64 yrs, 65-74 yrs, 75-84 yrs for 2000-2005. Acute coronary
event defined as acute myocardial infarction (AMI) and other acute and subacute forms of ischemic heart disease,
ICD-9, Code 411. Myocardial infarction defined as all diagnosis with principle diagnosis of AMI (ICD-9-CM code
410) or a secondary diagnosis of AMI where principal diagnosis indicated AMI complications. Two events occurring
within 28 days of each other were analysed as one single episode.
Biochemical verification: No
Notes Possible confounders are that measurement of troponin as a new diagnostic criteria for AMI became available in
hospitals in Rome during the study period. There was an increase in daily dose of cardiac medication such as statins
from 10 to 55 per 1000 residents when this study was carried out. Other outcomes are economic impact as measured
from cigarette sales in Rome, air quality by average concentrations of PM10, temperature and flu epidemics.
Eagan 2006
Methods Country: Norway
Setting: Hospitality premises
Design: Cohort study, pre and 5 months follow-up surveys. Analysis: McNemar’s test for change in symptom
prevalence and ANOVA for repeated measures. Chi 2 for the exposure variables, and test for trend for the symptom
variables to test differences in baseline characteristics by response or non-response at follow up.
Participants Employees in a random sample of companies.
Baseline: 1525 employees participated
Follow up: 906/1525 responded 5 months post-ban, 59% response rate
Cohort sample : Females 51.9%; Age 15-29 yrs 38%, 30-39 yrs 30%, 40+ 31.8%; Smokers (persistent and starters)
56%.
Missing outcome data: Used Chi 2 to test for differences in baseline characteristics between respondents and nonrespondents
at follow up. No difference except in response rate of smokers (57.4%) and nonsmokers (62.6%). No
difference between respondents and non-respondents in baseline prevalence for any of the respiratory symptoms.
Interventions Legislative smoking ban introduced in Norway on 1st June 2004 in indoor workplaces including smoking in bars,
nightclubs and restaurants.
Outcomes Self-reported smoking status
Self-reported exposure to SHS
Prevalence of self-reported respiratory symptoms before and 5 months post-ban. Respiratory symptoms included
were morning cough, daytime cough, phlegm cough, dyspnoea and wheezing.
Biochemical verification: No
Notes An incentive of prize money was offered to one randomly selected participant. Exposure to SHS and smoking status
were also recorded at baseline.
