Prevalence of and demographic, lifestyle, dietary factors associated with self-reported asthma in a non-probability sample of social-media-recruited adults residing in Kuwait
摘要
This cross-sectional study aimed to assess the prevalence of self-reported asthma in a non-probability sample of social-media-recruited adults in Kuwait and to examine the sociodemographic and lifestyle factors associated with self-reported asthma status in the study population.
MethodsThe data were collected from January 26, 2021, to February 3, 2021, using an e-questionnaire, which was administered through social media platforms. The prevalence (%) of self-reported asthma was computed. A multivariable log-binomial regression model was used to evaluate the association between the demographic and lifestyle factors with asthma status. The adjusted prevalence ratios (PRadjusted) and their corresponding 95% confidence intervals (CI) were computed from the estimated coefficients of the final model and used to intrepret the results.
ResultsOf 3572 respondents, most participants were females (78.30%), between the ages of 21 and 30 years (40.71%), Kuwaiti nationals (89%), college graduates (89.53%), had a family monthly income (Kuwaiti Dinars) of 2000 or more (45.49%), and married (55.15%). Prevalence of asthma (%) among the participants was 17.83% (637/ 3572). The final multivariable log-binomial regression model showed that the smoking-related behaviours significantly (p < 0.05) associated with asthma status were current smoking (current smoker vs. non-smoker: PRadjusted = 1.89; CI: 1.45–2.47) or age at initiation of smoking (age ≥ 15 years vs. < 15 years: PRadjusted = 2.37; 95% CI: 1.41–3.96; non-smokers: PRadjusted = 2.66; CI: 1.53–4.61). Moreover, the participants who reportedly consumed red meat five or more times per week had 32% more prevalence of asthma compared with non-consumers of red meat (PRadjusted = 1.32; CI: 0.98–1.77; p < 0.063). Additionally, compared with the 21-30-year-olds, the participants in the age band of 31–40 years had 31% more prevalence of asthma (PRadjusted = 1.31; CI: 1.10–1.57). Females, compared with males, were significantly more likely to be asthmatic (PRadjusted = 1.31; CI: 1.05–1.63). The other variables significantly (p < 0.05) associated with asthma status were nativity (Kuwaiti nationality vs. non-Kuwaiti non-Arab: PRadjusted = 2.46; CI: 1.20–5.07), and marital status (widowed vs. single: PRadjusted = 2.23; CI: 1.65–3.03).
ConclusionThis study provided evidence of a moderately high prevalence of asthma in a non-probability sample of social-media-recruited adults overrepresenting some social groups including females, young adults and highly educated participants in Kuwait. Current tobacco smoking, initiation of smoking at age ≥ 15 years were independently associated with asthma status. However, consumption of red meat at least five times a week was marginally associated with asthma status. These findings highlight the potential role of tobacco-related behaviors in asthma risk and support the need for targeted public health strategies, including smoking prevention and cessation programs. Further research is warranted to confirm these associations and to explore additional risk factors, such as genetic predisposition and exposure to secondhand tobacco smoke.
