Strachan et al. 1996; Butland and Strachan 2007 | 18,550 people born March 3–9, 1958, in England, Scotland, or Wales 5,801 contributed information at 7, 11, 16, 23, and 33 years of age | 1958–1991 |
Active cigarette smoking was associated with incidence of asthma or wheezing illness from 17 to 33 years of age (OR = 4.42; 95% CI, 3.31–5.92) Relapse after prolonged remission of childhood wheezing was more common among current smokers At 42–45 years of age, the proportions of incident asthma and incident wheeze without asthma associated with cigarette smoking were estimated to be 13% (95% CI, 0–26) and 34% (95% CI, 27–40)

Bodner et al. 1998 | Study of subjects aged 39–45 years derived from an Aberdeen cohort of 2,056 asymptomatic children originally studied in 1964 117 cases with adult-onset wheeze 277 controls | 1964–1995 |

Withers et al. 1998 | 2,289 children Baseline: 6–8 years of age Follow-up: 14–16 years of age Southampton, United Kingdom | Baseline: 1978–1980 Follow-up: 1987–1995 |
| Dose-response relationships observed |
Sears et al. 2003 | 1,037 children Birth cohort followed repeatedly from 9–26 years of age New Zealand | Baseline: 1972–1973 |
Smoking at 21 years of age predicted persistence of wheeze from the study onset (adjusted OR = 1.84; 95% CI, 1.13–3.00). Relapse of wheezing at 26 years of age after being wheeze free was significantly associated with smoking at 21 years of age in a univariate model (OR = 1.84; 95% CI, 1.11–3.04), but multivariate model controlling for bronchial hyperresponsiveness was not significant for relapse

For those with no respiratory symptoms at baseline, current smoking predicted development of wheeze at follow-up (OR = 2.8; 95% CI, 1.6–4.9 for girls; OR = 1.8; 95% CI, 0.9–3.9 for boys)

For those with no respiratory symptoms at baseline, current smoking predicted development of wheeze at follow-up, which was significant for girls (OR = 2.8; 95% CI, 1.6–4.9 for girls; OR = 1.8; 95% CI, 0.9–3.9 for boys)
