Sex- and Age-Specific Risk Factors for Asthma: A Comparative Analysis of Demographic, Clinical, and Comorbidity Profiles in Men and Women

Asthma is a multifactorial respiratory condition affected by demographic, clinical, and lifestyle factors. Recognizing sex-related differences in risk factors may help develop personalized preventive strategies and ultimately enhance clinical outcomes. This study aims to compare the characteristics of male and female patients with asthma and to identify the primary risk factors linked to the condition in each group as well. A comparative analysis was conducted using regression models to evaluate the association between asthma and potential risk factors. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate the strength of associations for men and women separately. In females, obesity (OR, 1.85; 95% CI, 1.24–2.75), chronic obstructive pulmonary disease (COPD) (OR, 3.37; 95% CI, 1.77–6.43), chronic sinusitis (OR, 4.37; 95% CI, 1.02–18.64), and hypothyroidism (OR, 1.79; 95% CI, 1.09–2.94) were significantly associated with asthma. In males, COPD was the strongest predictor (OR, 4.35; 95% CI, 1.18–15.97), while other factors showed weaker or non-significant associations. Age was not a significant predictor in either sex. The findings highlight important sex differences in the risk profile for asthma. These results underscore the need for sex-specific approaches in the prevention, diagnosis, and management of asthma.
