Methods Participants answered questions about their most recent hookup and feelings of regret. Results Frequency of engaging in a hookup was similar across gender and college context. Men and women were more likely to regret hookups with strangers and when alcohol was involved. Women had fewer regrets when their last hookup occurred with a partner they had also hooked up with in the past than when the hookup occurred only once with that partner. University students reported more regret when the hookup occurred with a stranger, occurred only one time, and when alcohol was used, but this was not found for community college students. Conclusions Future research should examine hookup experiences through a developmental lens. This study aimed to investigate interactions among physical fitness, sleep quality, sedentary behavior, and depression among female college freshmen. A cohort of 1,514 Chinese female college freshmen ( = 18.8 ± .63) were recruited from four universities. Participants completed a survey assessing depression, sleep quality (sleep duration and sleep onset latency), and sedentary behavior, and performed physical fitness measurements. Physical fitness indexes were associated with sleep quality and sedentary behavior ( < .05) but not with depression. Depression was positively associated with sedentary behavior and sleep onset latency, but negatively associated with sleep duration ( < .01). The model tests revealed that sleep quality ( = -.57, < .01) and sedentary behavior ( = .14, < .01) served as mediators between physical fitness and depression, respectively. Increasing sleep quality and minimizing sedentary behavior may build resilience to depression among Chinese femaledentary behavior may build resilience to depression among Chinese female college freshmen.
