European Studies Six studies on spousal smoking and nonsmoker lung cancer were conducted in Europe (Table 3).2,7,13,,19,23,26 Statistical significance was reported in two studies, both by the same research group.2'26 No major cohort study has yet been~conducted in~Europe. The cohort studied by Gillis, et al., and Hole, et al., although large, has few lung cancer deaths.7 4 i

Asian Studies. In contrast, 13 epidemiologic studies on spousal smoking and lung cancer in nonsmokers (one cohort, twelve case-control)~ have been conducted in China and Japan (hereafter, "Asian studies") (Table 2),1,4,10,12,15,17,18,20-22,27,28,29 Of this group, several studies report statistically significant relative risks. However, none of the reported relative risks is greater than 2.5; relative risks under 3.0 have been described as "weak" (see Criticisms section in this notebook). Of particular interest is the 1990 paper by Wu-Williams, et al., conducted in northeastern China.28 This paper reports a statistically significant negative risk associated with ETS exposure. Other factors (particularly indoor air quality) were reported to be associated with an elevated risk of lung cancer in the Wu-Williams, et al., study; such confounders were not always accounted'. for in the other Asian studies section on Confounders in this notebook).

Childhood Exposure to ETS and Adult Lung Cancer in Nonsmokers When the Janerich, et al., paper was published in 1990, the media focused on a sin le statistically significant risk ratio (OR) reported by the authors, i.e., an estimated OR of 2.07 (95% CI 1.16-3.68) for "household exposure to 25 or more smoker-years during: childhood and adolescence.."24 This OR is the only statistically significant estimate out of 13 exposure categories in the paper. A single statistically significant point estimate could have easily occurred by chance alone in a set of analyses this large. Only a few other studies have included questions concerning exposure to ETS during childhood, i.e., parental smoking. 5,9,11,12,15,23,25,27 Regarding these studies, Ernst Wynder and~ Geoffrey Kabat wrote in a 1990 publication: No consistent association has been reported for lung cancer and exposure to ETS in childhood, which might be expected to exert a greater effect, especially when followed by exposure throughout adulthood. Of course, recall of ETS exposure in childhood is more difficult than recall of such~ exposure in adulthood. (Wynder, E.L. and Kabat, G.C., "Environmental Tobacco Smoke and ~ Lung Cancer: A Critical Assessment," Indoor Air Quality, ed. H. ~ Kasu a (Berlin~ Heidelberg: Springer-Verlag, 1990): 5-15.) g , ~ Table 4 presents the reported risk estimates from the W C.J ~ studies (9 to-date) which discuss childhood ETS exposure and lung N i 5

Exposure to ETS in the Workplace and Lung Cancer in Nonsmokers The issue of ETS in the workplace is currently a focus of public interest, as evidenced by the 1990 draft Guide to Workplace Smoking Policies prepared by the United States Environmental Protection Agency. This document is based on the EPA's draft risk assessment, which used~ data from epidemiologic studies which assessed ETS exposure in terms of spousal smoking, not smoking in the workplace. The current epidemiologic data on workplace exposures to ETS and lung cancer in nonsmokers are reported in eleven studies which examined workplace exposure via questionnaire.8'9,11,13, 17,22-26,28 None of these studies provides adequate support for an increased risk of lung cancer associated with ETS exposure in the workplace. Only one study reports a single marginally statistically significant risk. The point estimates of the studies (in chronological order) are presented in Table 5. (In the table, "n.s." stands for "not significant.") - 7 -
