“…Our results indicate that dampened circadian activity rhythm, including lower MESOR, amplitude, and M10, was significantly associated with an increase in mood episode relapses. A prospective 18-month study of 80 patients with bipolar disorder reported an association between lower physical activity measured using the International Physical Activity Questionnaire and increased mood episodes [9]. Our findings support those of the previous study and further suggest that physical activity levels are mainly associated with the depressive episode relapses.…”

“…As a result, patients with bipolar disorder can face the dual risk of mental and physical problems. In contrast, exercise is reported to have a positive effect not only on mental problems, including mood symptoms and relapse of mood episodes, but also on physical problems, such as obesity, hypertension, and cholesterol [8,9,34,35]. Furthermore, we found that an increase in M10 from 133 to 240 counts/min (25th to 75th percentiles) was associated with a 42.8% decrease in mood episode relapses.…”

“…A systematic review of patients with bipolar disorder suggested that exercise was associated with positive effects on depressive symptoms, quality of life, and functioning [8]. A prospective cohort study of 80 patients with bipolar disorder reported that reduced physical activity measured using a questionnaire was associated with mood episode relapse and hospitalizations for psychiatric disorders [9]. The evidence indicates that physical activity levels are associated with mood symptoms in bipolar disorder.…”

Association between circadian activity rhythms and mood episode relapse in bipolar disorder: a 12-month prospective cohort study

A significant proportion of patients with bipolar disorder experience mood episode relapses. We examined whether circadian activity rhythms were associated with mood episode relapses in patients with bipolar disorder. This prospective cohort study included outpatients with bipolar disorder who participated in a study titled “Association between the Pathology of Bipolar Disorder and Light Exposure in Daily Life (APPLE) cohort study.” The participants’ physical activity was objectively assessed using a wrist-worn accelerometer over 7 consecutive days for the baseline assessment and then at the 12-month follow-up for mood episode relapses. The levels and timing of the circadian activity rhythms were estimated using a cosinor analysis and a nonparametric circadian rhythm analysis. Of the 189 participants, 88 (46%) experienced mood episodes during follow-up. The Cox proportional hazards model adjusting for potential confounders showed that a robust circadian activity rhythm, including midline-estimating statistic of rhythm (MESOR) and amplitude by cosinor analysis and 10 consecutive hours with the highest amplitude values (M10) by the nonparametric circadian rhythm analysis, was significantly associated with a decrease in mood episode relapses (per counts/min, hazard ratio [95% confidence interval]: MESOR, 0.993 [0.988–0.997]; amplitude, 0.994 [0.988–0.999]; and M10, 0.996 [0.993–0.999]). A later timing of the circadian activity rhythm (M10 onset time) was significantly associated with an increase in the depressive episode relapses (per hour; 1.109 [1.001–1.215]). We observed significant associations between circadian activity rhythms and mood episode relapses in bipolar disorder.

“…Even though the current focus is just on the range of studies that were conducted since 2015, in contrast to the relatively small amount of contradictory findings (e.g., [54•]), there was already an overwhelming body of evidence suggesting that the adoption of an active lifestyle was linked to a curtailment in one's probability of developing insomnia symptoms (e.g., [55, 56, 57•, 58-63]). More specifically, a good number of these research outcomes was also observed longitudinally (e.g., [56,58,59,61]). For instance, Chen and colleagues reported that physically idle individuals were more likely, in juxtaposition to those who have been involved in physical pursuits, to develop insomnia issues (with a hazard ratio of "1.22") across a span of 7 years (p. 189) [59], while similar outcomes were shown in a separate empirical investigation on female adults who have transformed from being physically idle to individuals who were intensely engaged in physical endeavors (versus those who have remained physically idle) (with an odds ratio of "0.17" after accounting for relevant factors) in a prospective investigation that spanned 10 years (p. 22) [58].…”

Purpose of Review For the most part of human existence, individuals have been living a rural lifestyle in a rural setting. However, such sleep-conducive conditions have largely been transformed dramatically by urbanization within a relatively short span of time in recent history, and the resulting evolved mechanisms-environment mismatch is theorized to bring about an increased risk for insomnia symptoms. This brief review of the recent literature is designed to evaluate the veracity of this proposition. Recent Findings The majority of recent findings have suggested that most proposed evolutionarily mismatched urban factors are indeed related to the presence of insomnia symptoms. However, there is a general paucity of longitudinal evidence (and for some other factors, a lack of enough evidence of any kind). Summary Although there is a preponderance of recent findings indicating a link between evolutionarily mismatched urban phenomena and insomnia symptoms, more longitudinal data are needed before any causative conclusion can be drawn.

“…According to World Health Organization’s definition, depression is defined as “an illness characterized by persistent sadness and a loss of interest in activities, accompanied by an inability to carry out daily activity” and the depressive symptoms could last for at least two weeks [ 5 ]. It is well-documented that participation in regular physical activity (PA) plays an important role in the prevention of developing depressive symptoms among adults [ 6 , 7 , 8 ]. Growing research noted that, however, people with depressive symptoms often do not meet daily PA recommendations [ 9 , 10 ], and college students who show depressive symptoms are less likely to participate in regular PA compared to their counterparts without depressive symptoms [ 10 , 11 ].…”

Longitudinal Effects of Motivation and Physical Activity on Depressive Symptoms among College Students

High prevalence of depression and physical inactivity have been consistently reported among college students, especially in females. Guided by Lubans et al.’s conceptual framework, the primary purpose of this study was to examine the longitudinal relationships of PA motivation with leisure-time PA and depressive symptoms among college students over one academic year. Employing a longitudinal repeated measure design, 1004 college students in China were recruited in this study (28.3% males and 71.7% females; M age = 18.93 ± 0.64 years; 18–22 years old). Participants completed previously validated questionnaires assessing PA motivation (perceived competence beliefs and task values toward PA), leisure-time PA participation, and depressive symptoms in Fall 2016 (Time 1) and Fall 2017 (Time 2). Both male and female college students showed a significant increase of depressive symptoms from freshmen to sophomores (p < 0.05). The regression models indicated that perceived competence beliefs and task values toward PA were significant predictors of depressive symptoms at Time 2 (p < 0.05) after controlling for Time 1 measures in males and females, respectively. Physically active college students consistently demonstrated higher PA motivation, and they displayed fewer depressive symptoms compared to inactive peers over time (p < 0.05). The findings suggest sex-specified motivational intervention strategies and PA promotion programs/opportunities are needed to reduce depression symptoms among college students over time.
