Asthma quality of life in Saudi Arabia: Gender differences.

OBJECTIVES: To explore potential gender differences in the factors associated with asthma-specific quality of life (AQL). METHODS: A cross-sectional study of consecutive series of adult patients attending primary care centers at three major hospitals in Riyadh, Saudi Arabia, was performed. AQL was measured using a standardized version of the AQL questionnaire (min = 1, max = 7), with higher scores indicating a better AQL. Multiple linear regression analysis was performed. RESULTS: The mean AQL was 4.3 (standard deviation [SD] = 1.5) for males and 4.0 (SD = 1.3) for females (p = 0.113). With each unit increase in asthma control, the AQL improved by 0.19 points (95% confidence interval [CI] = 0.14-0.23) in men and by 0.21 points (95% CI = 0.16-0.25) in women. Daily tobacco smoking was associated with a 0.72 point (95% CI = 0.14-1.30) decrease in the AQL among males. Women who had a household member who smoked inside the house had a significantly lower AQL (B = -0.59, 95% CI = -1.0 - -0.19). A monthly household income of 25,000 Saudi Riyals or more was associated with a better AQL among men (B = 0.51, 95% CI = 0.01-1.01), whereas being employed exhibited a protective effect in women (B = 0.48, 95% CI = 0.11-0.84). Higher levels of perceived asthma severity were associated with better AQL in women (B = 0.82, 95% CI = 0.36-1.28). CONCLUSIONS: Our findings revealed gender-specific differences in the correlates of AQL in Saudi Arabia, particularly in tobacco exposure, socio-economic factors and perceived asthma severity.

Interaction Effects of Happiness and Physical Activity on Smoking Initiation.

OBJECTIVE: Our aim was to assess the potential relationships among happiness, physical activity, and smoking initiation among undergraduate medical students in Saudi Arabia. METHODS: We performed a cross-sectional study of randomly selected first- to fifth-year undergraduate medical students. Smoking initiation was defined as "ever trying smoking a cigarette, waterpipe, cigar/cigarillo, or other type of tobacco, even one or 2 puffs." The short scale Oxford Happiness Questionnaire was used to assess each student's happiness. Multivariate logistic regression analysis was performed. RESULTS: Of the 406 students surveyed (208 boys, 198 girls), 86 (21.1%) had initiated smoking. We found an interaction between physical activity (PA) and happiness on smoking initiation (p-interaction = .012). Among boys with low levels of PA, lower levels of happiness were associated with a greater likelihood of smoking initiation (OR = 5.8, 95%CI = 1.9 - 17.5). Also, high levels of PA increased the chance of smoking initiation among male students with high levels of happiness (OR = 5.6, 95%CI = 2.1 - 14.5). CONCLUSION: Our results suggest that young men with low levels of happiness and low levels of PA, as well as high levels of PA and high levels of happiness, may be targeted as a priority population in tobacco control intervention programs.
