Table 2 Relationship between demographic and socioeconomic characteristics and sleep patterns. Notes: The table presents the results from the mixed-effects regression analysis, including individual random effects. N represents the number of observations. Each observation in the regression represents the total sleep aggregated for either the entire day, nighttime, or daytime. Sleep duration is measured in minutes, and sleep quality is rated on a four-point scale, with four indicating the best quality and one the worst. Social status comparison is a self-assessment of household social standing on a scale from 1 (low), 2 (average), to 3 (high). Living area is categorized from 1 (rural), 2 (semi-rural), to 3 (urban). Column (5) includes only individuals who get daytime sleep and Column (10) includes those who get daytime sleep within the subgroup experiencing insufficient nighttime sleep. *, **, and *** indicate statistical significance at the 0.10, 0.05, and 0.01 level, respectively. Standard errors are shown in parentheses.
