Smoke-Free Legislation and Asthma Hospital admissions for asthma in children younger than 15 years was studied in Scotland both before and after comprehensive smoke-free legislation was passed in March 2006. Monthly records were kept of the annualized percent change in asthma admissions, both before and after the legislation was passed. For the sample studied, before the legislation, admissions for asthma were increasing at a mean rate of 5.2 % per year. The standard error for this estimate is 0.7 % per year. After the legislation, admissions were decreasing at a mean rate of 18.2 % per year, with a standard error for this mean of 1.79 %. In both cases, the sample size is large enough to use a normal distribution. 1Mackay, D., et. al., "Smoke-free Legislation and Hospitalizations for Childhood Asthma," The New England Journal of Medicine, September 16, 2010; 363(12):1139-45.
