Relationships Among Smartphone Use, Physical Activity, and Quality of Life in Chinese College Students

Abstract

This study aimed to investigate the correlations between smartphone use, physical activity, and quality of life (QOL) among Chinese college students. We enrolled 6323 students who were chosen from three Chinese universities. All participants completed the World Health Organization QOL Scale-Brief, Smartphone Addiction Index, and Physical Activity Questionnaire-Short Form. Smartphone addiction was negatively related to QOL (β = −1.375, 95% CI [–1.442, –1.306]), whereas physical activity was positively related to QOL (β = .059, 95% CI [0.047, 0.071]). The presence of both smartphone addiction and insufficient physical activity decreased QOL scores when compared with the group with sufficient physical activity and non-smartphone addiction (β = −36.505, 95% CI [–39.046, –33.964]). Physical activity and smartphone use are potentially modifiable risk factors for poor QOL in college students. Thus, interventions to decrease smartphone use and promote physical activity could be beneficial for improving QOL in this population.

Association between dietary patterns and premenstrual disorders: a cross-sectional analysis of 1382 college students in China

“…However, the prevalence of PMDs in our cohort aligns with findings from other population-based studies. 3,4 Third, although our study has adjusted for several known confounders, there remains the potential for residual confounding due to uncollected factors (e.g., physical activities) 68,69 and possible misclassification of confounders, such as the use of self-reported weight and height for BMI calculation. 70 Fourth, the participation rate was fairly good in the School of Medicine, while the lower rate in other schools is due to the ongoing data collection.…”

Perception of benefits‐barriers of exercise, physical activity level, and body awareness in women with premenstrual syndrome

“…PMS can lead to significant distress and a decline in functional capacity. [1][2][3][4][5] Previous studies have indicated a relatively high frequency of PMS. Worldwide, it has been reported that approximately 47.8% of reproductive-age women are affected by PMS, with 5%-8% experiencing moderate to severe symptoms that are related to functional impairment.…”

“…Common manifestations of PMS include alterations in appetite, irritability, depression, anxiety, difficulty concentrating, headaches, weight gain, constipation, fatigue, abdominal and lower back pain, breast swelling and tenderness, as well as mood swings. PMS can lead to significant distress and a decline in functional capacity 1–5 …”

“…However, previous studies have presented conflicting evidence regarding the association between exercise and PMS. While several research studies have reported that regular exercise can relieve premenstrual symptoms, 1,3,5 other studies have found no significant relationship between physical activity and the prevalence or severity of PMS symptoms 11 . Notably, Czajkowska et al reported that competitive sports may actually contribute to PMS and premenstrual dysphoric disorder 12 …”

"Comparative Analysis of the Features of the Menstrual Cycle in Students Going into Sports and Physical Education at The University"

“…Many of them started their sports activities in the prepubertal and pubertal period, even before their first menstruation, before their puberty [1][2][3][4][5]. The intensity of physical and psycho-emotional stress increases significantly among female students at a physical education university, who specialize in a particular sport, then among their peers who are not so actively involved in physical education and sports [3][4][5][6][7][8][9]. The intensity of studying at the university, combining studies and sports, individual nutritional characteristics of girls, the presence or absence of a few bad habits, the formation, maintenance and level of their reproductive health is a very relevant topic for studying medical, biological and psychological processes occurring in the body.…”
