Int. J. Environ. Res. Public Health 2011, 8 2.4. Data Analysis The Statistical Package for the Social Science (SPSS) version 17 was used for data analysis. The alpha level was set at 0.05 to determine statistical significance. Descriptive analysis were conducted to characterize self reported SHS exposure, worksite smoking policy, husband’s smoking status, knowledge and attitudes toward SHS exposure, and SHS avoidance practices. Chi-square tests were performed to estimate the bivariate difference between anti-smoking workplace policies, husband smoking and avoidance of SHS exposure by subjects. Avoidance behaviors were also compared between subjects in clerical positions and clerical administrator positions versus those in academic positions using the Analysis of Variance. 4211 3. Results 3.1. Sample Characteristics Participants’ age ranged between 28 and 58 years old with a mean of 34.6 years old (SD ± 7.2). The results showed that 82.3% were working in clerical administrative professional jobs, while 17.7% were working in academic positions. All participants had a college graduate degree or higher. All participants were married and living with their husbands in the same house. As mentioned in the sample’s selection criteria, none of the subjects were smokers or had smoked within the prior year. The majority of participants (67.5%) spent most of their time in an indoor environment. 3.2. Worksite Smoking Policies Despite the fact that workplace anti-smoking policies existed at the time of the survey, when participants were asked about the presence such policies only 52.2% reported being aware of these policies. Nearly one-third (32.1%) did not think that their university had anti-smoking policies, and 15.8% were not aware whether such policies existed. Furthermore, when asked about details of existing indoor smoking policies, 54.5% reported restrictions in all closed indoor areas, while 22% reported that smoking was allowed in some closed areas, and 5.7% reported that indoor smoking was allowed in all areas. Moreover, 17.7% reported not knowing anything related to indoor smoking policies, this is despite their existence when the study was conducted. 3.3. Husband Smoking More than half (55%) of participants reported living with a smoking husband; the average number of cigarettes smoked by the husbands was 23.2 (SD ± 11.3) per day. More than one-third (367%) of husbands smoked inside their homes; and many (24.9%) subjects reported that other family members also smoked in the home. In total, almost two thirds (59.6%) of subjects reported that someone (husband or other family member) smoked inside the house. When asked to estimate daily SHS exposure inside and outside their homes, subjects reported a mean of 5.5 (SD ± 5.5) hours per day. Additionally, subjects reported SHS exposure for an average of 6 (SD = 6.2) days per week in any setting.
