Note. n = 313 participants, n = 6,262 assessments. The outcome variable was the total number of types of waking activities that participants endorsed every 3 hr throughout the day (14 in total), participants’ averaged activity count and percentage of time being sedentary every 3 hr.

^aHaving any encounters with a close tie (or a peripheral tie) every 3 hr throughout the day.

^b1 = male, and 0 = female.

^c1 = no formal education, 2 = elementary school, 3 = some high school, 4 = high school, 5 = some college, 6 = college, 7= some post college education, 8 = advanced degree.

^d1 = poor, 2 = fair, 3 = good, 4 = very good, and 5 = excellent.

^e1= married, and 0 = not married.

^fCoded as 1= minority, and 0 = nonminority.
