Notes: **: p < 0.01, *: p < 0.05, †: p < 0.1. Gender (man = 0, woman = 1). The figure for age is the actual age (non-logarithm). Occupation: no job = 0, otherwise = 1. Marital status: unmarried, divorced, or bereaved = 0, married = 1. The figures in parentheses concerning exercise/eating are based on the calculated values of Pearson correlation coefficients. The figure in brackets indicates the order (from the highest) of the magnitude concerning the estimated coefficient for each variable. The italicized figures in parentheses indicate the number of variables in each category; refer to the information below for biological factors. The blank space indicates that the relevant variable is not asked in Surveys 1 or 2. “Exercise” and “Eating” are separately asked in Survey 1, while an integrated item, “Exercise/Eating,” is asked in Survey 2.
