  1. The regression coefficients (B) with (95% confidence interval) from generalized linear mixed model controlling for gender and age with urban-rural area as a random effect (except for urban-rural area itself that no random effect was considered). ⁎p < 0.05; **p < 0.01
  2. Reference categories: urban-rural areas: inner urban, outer urban, or peri-urban; unable to work due to diseases/injuries: sometimes reduce in work pace or changes to work is needed, often reduce in work pace or changes to work is needed, part time work on account of illness is needed, or totally unable to work; frequency of physical activity through gardening: once a month or less, or not at all; occupational group: directors and senior management, senior advisors and senior officials, advisors and officials, office workers and customer service representatives, and cannot say; difficulty of a 2-km run without breaks: with much difficulty or cannot at all; basic education: matriculation examination; sleeping problems: considerable problems and major problems, or severe insomnia; frequency of exercise through walking: once a month or less, or not at all; total amount of sleep: significantly insufficient or totally insufficient; difficulty of a 5-km run without breaks: with much difficulty or cannot at all; enjoyment of daily activities: now and then, hardly ever, or never; signs and symptoms: considerable signs and symptoms, strong signs and symptoms, or intolerable signs and symptoms; frequency of exercise through swimming: once a month or less, or not at all; considered retirement before the retirement age: have often, or have applied for a pension
