Multivariable linear regression between different domains of Short form Health Survey questionnaire (SF-36) and sense of coherence (SOC-13), self-rated health (SRH), gender, conditions and diseases remaining after backward elimination process using exclusion criteria p > 0.01
Predictors included in the first step of the backward selection were female sex, dizziness, Sense of Coherence (SOC total score), diabetes, hypertension, hyper or hypothyroidism, lung disease (chronic bronchitis, asthma, chronic obstructive pulmonary disease), cardiac infarction/heart failure, prior stroke, vision or hearing impairment and joint/back problems
