Notes: the reference category for the dependent variable is average level of physical activity. ^aThe reference category for steady income is NO. ^bThe reference category for per capita income is below USD 271. ^cThe reference category for savings is NO. ^dThe reference category for indebtedness is YES. β: assessment value of model parameters, SE: asymptotic standard error β, Wald χ²: parameter significance, p: Wald χ² probability value, OR: odds ratio, and CI: confidence interval.
