Table 4 Multivariate analyses of predictive factors for lung function impairment
A: Men | ||||||
Model 1 | Model 2 | |||||
Factors | Odds ratio | 95% CI | P value | Odds ratio | 95% CI | P value |
Smoking status (ever versus never) | 2.67 | (1.35–5.27) | 0.0046 | 2.5 | (1.25–4.97) | 0.0093 |
COPD assessment score | 1.06 | (1.01–1.12) | 0.022 | 1.06 | (1.01–1.12) | 0.03 |
Handgrip strength (per 5 kg) | 0.74 | (0.58–0.94) | 0.013 | 0.73 | (0.57–0.92) | 0.011 |
Sit to stand test (per one time) | 0.99 | (0.94–1.03) | 0.51 | |||
Ever passive smoking | 2.31 | (0.77–6.89) | 0.14 | |||
Present passive smoking at home | 1.74 | (0.83–3.68) | 0.15 | |||
Passive smoking at home in childhood | 2.71 | (1.16–6.32) | 0.021 | |||
B: Women | ||||||
Factors | Odds ratio | 95% CI | P value | |||
Smoking status (ever versus never) | 0.94 | (0.31–2.81) | 0.91 | |||
Hospitalization due to respiratory diseases in childhood | 25,900,000 | (0.00 - Inf) | 0.99 | |||
Dyslipidemia | 0.47 | (0.17–1.24) | 0.13 | |||
Handgrip strength (per 5 kg) | 0.99 | (0.91–1.08) | 0.78 | |||
Sit to stand test (per one time) | 0.97 | (0.91–1.04) | 0.39 | |||
Odds ratios and P values were estimated by using logistic regression analyses adjusted by age, BMI, and smoking history (ever smoking or not). In men, model 1 is adjusted for smoking status, CAT score, hand grip strength, Sit to stand test and all types of passive smoking, while model 2 is adjusted for present and previous passive smoking at home instead of all types of passive smoking. CAT; COPD assessment test, CI; confidence intervals. | ||||||
