Abstract
BACKGROUND Lung health is increasingly recognized as an essential factor in mental health. However, prospective evidence on lung function with incident depression remains to be determined. The study aimed to examine the prospective association between impaired lung function and incident depression and the underlying biological mechanisms. METHODS This prospective cohort study comprised 280,032 non-depressed individuals with valid lung function measurements from the UK Biobank. Lung function was assessed through the forced vital capacity (FVC) or forced expiratory volume in 1 s (FEV1). Cox proportional hazard models were applied to estimate the associations between lung function and incident depression. Mediation analyses were fitted to investigate the potential mediating role of biomarkers and metabolites in the association. RESULTS A total of 9514 participants (3.4%) developed depression during a median follow-up of 13.91 years. Individuals in the highest quartile had a lower risk of depression (FVC % predicted: HR = 0.880, 95% CI = 0.830-0.933; FEV1% predicted: HR = 0.854, 95% CI = 0.805-0.905) compared with those in the lowest quartile of the lung function indices. Additionally, the restricted cubic splines suggested lung function indices had reversed J-shaped associations with incident depression (nonlinear P < 0.05 for FVC % predicted and FEV1% predicted). Impaired lung function yielded similar risk estimates (HR = 1.124, 95% CI = 1.074-1.176). Biomarkers involving systemic inflammation, erythrocytes, and liver and renal function may be potential mediators in the lung function-depression association. CONCLUSIONS This study revealed that the higher risk of developing depression was associated with impaired lung function. Also, the association might be partially mediated by biomarkers including systemic inflammation, erythrocytes, and liver and renal function, though these mediation findings should be interpreted with caution due to potential temporal ambiguity.

Abstract
BACKGROUND Substantial evidence indicates that experiencing physical abuse and neglect during childhood significantly elevates the likelihood of developing depression in adulthood. Nevertheless, there remains a dearth of understanding regarding the mechanisms underpinning this correlation. OBJECTIVE In this study, we aimed to examine the associations of childhood physical abuse and physical neglect with depression using follow-up data from UK Biobank and quantified the contribution of smoking, insomnia, and BMI in these associations. PARTICIPANTS AND SETTINGS This study included 144,704 participants (64,168 men and 80,536 women) from UK Biobank, most of whom were white (97 %). METHODS Physical abuse and physical neglect were measured using two items of Childhood Trauma Screener (CTS). Data on the incidence of depression were obtained from primary care, hospital inpatient records, self-reported medical conditions, and death registries. We used a sequential mediation analysis based on the "g-formula" approach to explore the individual and joint effects of potential mediators. RESULTS The depression incidence rate was 1.85 per 1000 person-years for men and 2.83 per 1000 person-years for women, respectively. Results of Cox proportional risk regression showed that physical abuse (HRs: 1.39-1.53, P < 0.001) and physical neglect (HRs: 1.43-1.60, P < 0.001) are associated with depression. Smoking, insomnia, and BMI together mediated 3 %-26 % of the associations. CONCLUSIONS These findings contribute to our understanding of how physical abuse and physical neglect influence depression. Furthermore, a more effective reduction in the burden of depression can be achieved by managing modifiable mediators.

Abstract
PURPOSE This longitudinal data analysis examined the bidirectional relationships between sleep problems and suicidal thought (ST)/attempt (SA) in a large sample of Chinese adolescents. METHODS A total of 6995 adolescents (mean age = 14.86 years and 51.4% males) participated in a 3-wave longitudinal study of behavior and health in Shandong, China. A self-administered questionnaire and standardized scales were used to assess ST, SA, sleep duration, insomnia, daytime sleepiness, and behavioral/emotional problems in 2015 (T1), 1 year later (T2), and 2 years later (T3). Path analyses were performed without and with adjustment for covariates, including gender, grade level, chronic diseases, cigarette smoking, alcohol use, anxiety/depressive symptoms, paternal education, and family economic status. RESULTS The prevalence rates of short sleep (<7 h/night), insomnia symptoms, and daytime sleepiness were 46.9-58.8%, 16.0-19.4%, and 25.1-25.3% at T1, T2, and T3, respectively. The rates of past-year ST and SA were 9.1-12.4% and 1.6-2.4% at T1, T2, and T3, respectively. Path analyses showed that short sleep, insomnia, and daytime sleepiness predicted subsequent ST, and vice versa. Daytime sleepiness and SA predicted each other 1 year later. Sleep problems and ST/SA in the previous year significantly predicted themselves in the follow-up year. STUDY LIMITATION All data were based on self-report. CONCLUSION Short sleep, insomnia, and daytime sleepiness all had bidirectional relationships with ST. Daytime sleepiness and SA were bidirectionally linked. Our findings suggest that interventions should be taken for both night sleep disturbances and daytime sleepiness to prevent suicide. Adverse sleep outcomes in suicidal adolescents should be assessed, which can in turn increase suicide risk.

Abstract
STUDY OBJECTIVES Little empirical work has investigated the associations between life stress (LS), insomnia, depression, and suicidality in multi-wave longitudinal studies. With three waves of data collection 1-year apart, this longitudinal study with a large sample of adolescents examined the predicting effects of LS on suicidality 1-year later and 2 years later and the mediating roles of insomnia and depression in the LS-suicidality link. METHODS A total of 6995 adolescents (mean age = 14.86 years, 51.4% male) participated in a three-wave longitudinal study of behavior and health in Shandong, China. A self-administered structured questionnaire and standardized scales were used to assess suicidality (including suicidal thought [ST], suicide plan [SP], and suicide attempt [SA]), LS, insomnia, and depression in 2015 (T1), 1-year later (T2), and 2 years later (T3). Mediation effects were examined with path models. RESULTS The overall prevalence rates of past-year suicidality were 13.4% at T1, 10.0% at T2, and 9.5% at T3, respectively. The prevalence rates of suicidality across T1-T3 significantly increased with elevated levels of baseline LS, insomnia, and depression (p < .001). Path models indicated that the relationship between baseline LS and suicidal ideation (i.e., ST/SP) 2 years later was significantly mediated by both insomnia and depression. Depression was also a significant mediator between LS and SA. CONCLUSIONS LS is a significant predictor of suicidality 1-2 years later in adolescents. Depression mediates the association between LS and suicidal ideation and suicide attempt while insomnia appears to be a mediator for suicidal ideation rather than suicide attempt.

Abstract
BACKGROUND Epidemiological data on the association between romantic experiences and sleep in adolescents are limited. This study examined the associations of starting a romantic relationship (SRR) and romantic breakups with insomnia symptoms and sleep duration in adolescents. METHODS A total of 7,072 Chinese adolescents were surveyed in November-December 2015 and 1 year later. A self-administered questionnaire was used to assess SRR, romantic breakups, sleep duration, insomnia symptoms, depressive symptoms, substance use, and demographics. RESULTS The mean age of the sample was 14.58 (SD = 1.46) years and half were female. SRR only, breakups only, and both (SRR + breakups) in the past year were reported by 7.0%, 8.4%, and 15.4% of the sample, respectively. At the baseline and 1-year follow-up, 15.2% and 14.7% of the sample had insomnia symptoms and 47.7% and 42.1% reported short sleep duration (<7 h/night), respectively. After adjusting for depressive symptoms, substance use, and demographics, SRR and breakups were significantly associated with 35-45% increased odds of insomnia symptoms at baseline. SRR + breakups were significantly associated with short sleep duration (OR = 1.28, 95%CI = 1.05-1.56). SRR (OR = 1.61, 95%CI = 1.16-2.23) and breakups (OR = 1.43, 95%CI = 1.04-1.96) were significantly associated with increased odds of incident insomnia symptoms at 1-year follow-up. These associations were stronger in younger adolescents (<15 years) than in older adolescents (≥15 years), especially in girls. CONCLUSIONS The findings suggest that SRR and breakups are associated with insomnia symptoms and short sleep duration, underscoring the importance of romantic relationships education and management of romantic stress for healthy sleep especially in early adolescent girls.

Abstract
OBJECTIVE To systematically review the association between psychological pain and suicidality in patients with major depressive disorder (MDD). METHOD The databases of PubMed, Web of Science and PsycINFO were used to search and articles were screened for inclusion and exclusion criteria until February 2022. Two researchers independently screened the papers, extracted data, and evaluated the risk of bias of the included studies. Comprehensive Meta-Analysis software (CMA) was used for meta-analysis and the combined OR (95 % CI) values were calculated. RESULTS A total of 7 articles were included, with a sample size of 1364. The present study showed that psychological pain was a risk factor for suicidality in patients with MDD (OR = 1.322, 95 % CI:1.165-1.500). After Duval and Tweedie trim and fill to rectify potential publication bias, psychological pain was still a risk factor for suicidality in patients with MDD [OR = 1.196 (95 % CI: 1.030-1.388), P < 0.001]. Subgroup analyses showed that average age ≥ 40 [r = 0.57 (95 % CI: 0.32-0.81), P < 0.001] was moderating variable for psychological pain and suicidality. CONCLUSIONS Reducing psychological pain in MDD patients is somewhat important for preventing their suicidality, especially for the patients with advancing age.

Abstract
BACKGROUND There is increasing evidence for the role of environmental factors and exposure to the natural environment on a wide range of health outcomes. Whether exposure to green space, blue space, and the natural environment (GBN) is associated with risk of psychiatric disorders in middle-aged and older adults has not been prospectively examined. METHODS Longitudinal data from the UK biobank was used. At the study baseline (2006-2010), 363,047 participants (women: 53.4%; mean age 56.7 ± 8.1 years) who had not been previously diagnosed with any psychiatric disorder were included. Follow-up was achieved by collecting records from hospitals and death registers. Measurements of green and blue space modeled from land use data and natural environment from Land Cover Map were assigned to the residential address for each participant. Cox proportional hazard models with adjustment for potential confounders were used to explore the longitudinal associations between GBN and any psychiatric disorder and then by specific psychiatric disorders (dementia, substance abuse, psychotic disorder, depression, and anxiety) in middle-aged and older adults. RESULTS During an average follow-up of 11.5 ± 2.8 years, 49,865 individuals were diagnosed with psychiatric disorders. Compared with the first tertile (lowest) of exposure, blue space at 300 m buffer [hazard ratio (HR): 0.973, 95% confidence interval (CI): 0.952-0.994] and natural environment at 300 m buffer (HR: 0.970, 95% CI: 0.948-0.992) and at 1000 m buffer (HR: 0.975, 95% CI: 0.952-0.999) in the third tertile (highest) were significantly associated with lower risk of incident psychiatric disorders, respectively. The risk of incident dementia was statistically decreased when exposed to the third tertile (highest) of green space and natural environment at 1000 m buffer. The third tertile (highest) of green space at 300 m and 1000 m buffer and natural environment at 300 m and 1000 m buffer was associated with a reduction of 30.0%, 31.8%, 21.7%, and 30.3% in the risk of developing a psychotic disorder, respectively. Subgroup analysis suggested that the elderly, men, and those living with some comorbid conditions may derive greater benefits associated with exposure to GBN. CONCLUSIONS This study suggests that GBN has significant benefits for lowering the risk of psychiatric disorders in middle-aged and older adults. Future studies are warranted to validate these findings and to understand the potential mechanistic pathways underpinning these novel findings.

Abstract
Epidemiological data on premenstrual syndrome (PMS) in Chinese adolescents are limited. This study reported the prevalence and associated factors of PMS in a large sample of Chinese adolescents. A total of 5099 adolescent girls who had menarche participated in the baseline survey of Shandong Adolescent Behavior and Health Cohort study in Shandong, China. A self-administered questionnaire was used to ask about PMS, age at menarche, menstrual cycle interval, menstrual flow length, menstrual regularity, period pain, body weight and height, trait anger, stressful life events, and demographics. The mean age of the sample was 15.19 years (SD = 1.32). The overall prevalence of PMS was 24.6%. The prevalence rates of PMS-anxiety, PMS-water retention, PMS-craving, and PMS-depression were 18.9%, 4.0%, 7.9%, and 11.5%, respectively. The most common symptoms were premenstrual irritability (54%) and fatigue (52.5%). Stepwise logistic regression showed that high levels of life stress (OR 2.26), high levels of trait anger (OR 4.65), alcohol consumption (OR 1.28), menstrual cycle interval ≤ 24 days (OR 1.45), and mild (OR 1.50), moderate (OR 2.57) or severe period pain (OR 4.84) were all significantly associated with increased likelihood of PMS. In conclusion, approximately 1 in 4 Chinese adolescent girls suffered from PMS. Multiple psychosocial and menstrual factors were associated with PMS. Further research is needed to understand developmental changes of PMS and its long-term impacts on psychosocial wellbeing in Chinese adolescent girls.

Abstract
BACKGROUND Mental health literacy (MHL) is essential to mental health. Symptoms of depression and anxiety are significant antecedents and closely related to suicide among college students. Few studies have explored the mediating role of depressive and anxiety symptoms between MHL and suicidal ideation. METHODS 5578 college students were included in the analysis. The online Wenjuanxing platform was used to collect data from November 2020 to March 2021. The bootstrapping method was used to test the mediating role of depressive and anxiety symptoms in the links between MHL and suicidal ideation. RESULTS Approximately 18.8 % of Chinese college students in our study reported having suicidal ideation. MHL exhibited a significant and negative correlation with depressive symptoms, anxiety symptoms, and suicidal ideation, whereas depressive and anxiety symptoms correlated significantly and positively with suicidal ideation. Compared with the lowest MHL quartile, the 3rd and 4th quartiles of MHL were associated with a significantly lower risk of suicidal ideation after adjusting for various confounding factors. Depressive and anxiety symptoms partially mediated the relationship between MHL and suicidal ideation, and the mediating effect of depressive symptoms was significantly greater than that of anxiety symptoms. LIMITATIONS This study was a cross-sectional survey. Future longitudinal studies on this relation are needed. CONCLUSIONS Depressive and anxiety symptoms mediate the relationship between MHL and suicidal ideation. Comprehensive school-based specific psychological education programs are needed to improve college students' MHL and change their attitudes toward mental health services.

Abstract
BACKGROUND Although many studies have reported on the associations between the amount of physical activity (PA) and the transitions of cardiometabolic multimorbidity (CMM), the evidence for PA intensity has not been fully evaluated. OBJECTIVE This study aimed to explore the impact of PA intensity on the dynamic progression of CMM. METHODS The prospective cohort of this study using data from the UK Biobank included 359,773 participants aged 37-73 years who were recruited from 22 centers between 2006 and 2010. The diagnoses of CMM, which included the copresence of type 2 diabetes (T2D), ischemic heart disease, and stroke, were obtained from first occurrence fields provided by the UK Biobank, which included data from primary care, hospital inpatient record, self-reported medical condition, and death registers. The PA intensity was assessed by the proportion of vigorous PA (VPA) to moderate to vigorous PA (MVPA). Multistate models were used to evaluate the effect of PA intensity on the dynamic progression of CMM. The first model (model A) included 5 transitions, namely free of cardiometabolic disease (CMD) to first occurrence of CMD (FCMD), free of CMD to death, FCMD to CMM, FCMD to mortality, and CMM to mortality. The other model (model B) used specific CMD, namely T2D, ischemic heart disease, and stroke, instead of FCMD and included 11 transitions in this study. RESULTS The mean age of the included participants (N=359,773) was 55.82 (SD 8.12) years at baseline, and 54.55% (196,271/359,773) of the participants were female. Compared with the participants with no VPA, participants with intensity levels of >0.75 to <1 for VPA to MVPA had a 13% and 27% lower risk of transition from free of CMD to FCMD (hazard ratio [HR] 0.87, 95% CI 0.83-0.91) and mortality (HR 0.73, 95% CI 0.66-0.79) in model A, respectively. The HR for the participants with no moderate PA was 0.82 (95% CI 0.73-0.92) compared with no VPA. There was a substantially protective effect of higher PA intensity on the transitions from free of CMD to T2D and from T2D to mortality, which reveals the importance of PA intensity for the transitions of T2D. More PA and greater intensity had a synergistic effect on decreasing the risk of the transitions from free of CMD to FCMD and mortality. Male participants, younger adults, adults with a higher BMI, current or previous smokers, and excessive alcohol drinkers could obtain more benefits from higher PA intensity for the lower risk of at least 1 transition from free of CMD, then to CMM, and finally to mortality. CONCLUSIONS This study suggests that higher PA intensity is an effective measure for preventing CMM and mortality in the early period of CMM development. Relevant interventions related to higher PA intensity should be conducted.

Abstract
OBJECTIVE This study explored the temporal and spatial trends in road traffic fatalities in Shandong Province from 2001 to 2019 and discusses the possible influencing factors. METHODS We collected data from the statistical yearbooks of the China National Bureau of Statistics and the Shandong Provincial Bureau of Statistics. Join-point Regression Program 4.9.0.0 and ArcGIS 10.8 software were used to analyze the temporal and spatial trends. RESULTS The mortality rate of road traffic injuries in Shandong Province decreased from 2001 to 2019, with an average annual decrease of 5.8% (Z = -20.7, P < 0.1). The three key time points analyzed in the Join-point regression model roughly corresponded to the implementation times of traffic laws and regulations in China. The temporal trend in case fatality rate in Shandong Province from 2001 to 2019 was not statistically significant (Z = 2.8, P < 0.1). The mortality rate showed spatial autocorrelation (global Moran's I = 0.3889, Z = 2.2043, P = 0.028) and spatial clustering. No spatial autocorrelation was observed in the case fatality rate (global Moran's I = -0.0183, Z = 0.2308, P = 0.817). CONCLUSIONS The mortality rate in Shandong Province decreased significantly over the studied period, but the case fatality rate did not decline significantly and remains relatively high. Many factors influence road traffic fatalities, among which laws and regulations are the most important.

Abstract
BACKGROUND Adolescents with daytime sleepiness have been demonstrated to have a higher level of suicidal risk than those without. Currently, few studies had examined the pathway from daytime sleepiness to suicidal risk among female adolescents. This study aimed to explore the association among menstrual pain, daytime sleepiness, and suicidal risk among female adolescents in China. METHODS Of 7072 adolescents who participated in the follow-up survey of Shandong Adolescents Behavior & Health Cohort (SABHC), 3001 were female adolescents who had begun to menstruate and included for the analysis. A structured self-administrated questionnaire was used to measure menstrual pain, daytime sleepiness, suicidal risk and demographic characteristics. Participants were first surveyed in November-December 2015 and resurveyed 1 year later. RESULTS Of 3001 participants, 11.43 % had suicidal risk, 79.8 % experienced menstrual pain. Cross-lagged analysis showed that there was cause-and-effect relationship between menstrual pain and daytime sleepiness. Moderate (OR = 1.79, 95%CI: 1.22-2.63) and severe (OR = 2.73, 95%CI: 1.80-4.12) menstrual pain (follow-up) were associated with suicidal risk (follow-up). Daytime sleepiness (baseline: OR = 1.04, 95%CI: 1.02-1.06, follow-up: OR = 1.07, 95%CI: 1.05-1.09) had effects on suicidal risk (follow-up). Mediation analysis showed that menstrual pain played a partially mediating role between daytime sleepiness and suicidal risk, with the indirect effect being 0.002 (95%CI: 0.001-0.004). LIMITATIONS All data were self-reported. CONCLUSIONS Menstrual pain and daytime sleepiness had effects on each other, and they both were the risk factors of suicidal risk. Among female adolescents, the association between daytime sleepiness and suicidal risk could be partially mediated by menstrual pain. Releasing the menstrual pain of female adolescents with daytime sleepiness could reduce their suicidal risk.

Abstract
BACKGROUND Maltreatment is a significant predictive factor for self-harm in adolescents. Internalizing and externalizing problems are both common psychopathological issues in adolescents. This study aimed to look into the link between maltreatment and self-harm in a large sample of adolescents in the UK, as well as the mediating effects that internalizing and externalizing problems play in this link. METHODS Data were pulled from the UK Millennium Cohort Study, and a total of 8894 adolescents were included in this analysis. All variables were assessed by Questionnaires. Path analysis was performed to assess the mediating effects of internalizing and externalizing problems in the link between maltreatment and self-harm. RESULTS 23.4 % of samples reported self-harm incidents during the preceding 12 months. Emotional abuse and physical abuse were significantly related to self-harm, and adolescents who had experienced multiple forms of maltreatment were more prone to self-harm. Mediation analysis revealed that internalizing problems were the primary mediator in the link between emotional abuse and self-harm, with the mediation effect size being 0.29. Internalizing and externalizing problems performed similarly in the link between physical abuse and self-harm, with mediation effect sizes of 0.23 and 0.19, respectively. LIMITATIONS The majority of the data was gathered through self-reporting. CONCLUSIONS Emotional abuse and physical abuse were significant predictors of self-harm, and their links with self-harm were partially mediated via internalizing and externalizing problems. Better supervision of maltreatment, and timely intervention for both internalizing and externalizing problems, are critical in preventing self-harm among adolescents.

Abstract
This study aims to explore the joint associations of physical activity and lifetime depression with all-cause and cause-specific mortality. The present study using data from UK Biobank, included 316568 participants aged 37 to 73 years recruited from 22 centers between 2006 and 2010. Total physical activity (TPA), moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA), assessed by metabolic equivalent task (MET) were used and Cox-proportional hazard models were performed in this study. The incidence rate of all-cause, CVD, and cancer mortality was 4.35(95%CI: 4.29-4.42), 0.69 (95%CI: 0.67-0.72), and 2.23 (95%CI: 2.19-2.28) per 1000 person-years after an average follow-up time of 12.49 years. Lower levels of TPA, MVPA, and VPA were all independently associated with elevated risk of all-cause and cancer mortality. Lifetime depression was significantly associated with increased risk of all-cause (HR=1.46, 95%CI: 1.40-1.52), CVD (HR=1.48, 95%CI: 1.33-1.64), and cancer mortality (HR=1.13, 95%CI: 1.06-1.21). Significant interactive effect of low levels of TPA, MVPA, and VPA and lifetime depression on all-cause mortality were found in this study. The risk of all-cause mortality associated with lifetime depression was deteriorated with low levels of physical activity. Relevant interventions for regular PA should be performed among depressed population.

Abstract
BACKGROUND The evidence for the association of weight control attempts with suicidality by objective weight status, subjective weight perception, and distorted weight perception among adolescents was limited. METHODS Data were extracted from a national representative sample of Youth Risk Behavior Surveys in the United States from 2011 to 2019. Binary logistic regression models with complex sampling designs were used to explore the association of weight control attempts, objective weight status, and weight perception with suicidality. FINDINGS The adolescents attempting to lose weight had higher weighted prevalence of suicidal ideation, suicide plan, suicide attempt, and suicide attempt with medical treatment compared with other attempts of weight control. Totally, attempting to lose weight was significantly associated with increased risk of suicidal ideation (OR: 1.17, 95%CI: 1.05-1.30) and suicide attempt (OR: 1.26, 95%CI: 1.10-1.46) when adjusting objective weight status, weight perception and all other covariates. In the subgroup analyses, attempting to lose weight was significantly associated with increased risk of suicidality in the adolescents of normal weight, underweight, perceived normal weight, perceived underweight, right estimation of objective weight status. LIMITATIONS Uncertain causal relationship existed because of cross-sectional design. CONCLUSIONS The risk of suicidality associated with weight control attempts varied among different subgroups. The findings in this study suggest that not only objective weight status but also weight perception should be with consideration when performing weight control attempts.

Abstract
This study aims to explore the joint associations of shift work and sleep patterns with incident depression. The present prospective cohort using data from UK biobank, included 220,651 participants aged 38 to 71 years recruited between 2006 and 2010. Every participant finished a self-completed touch-screen questionnaire. Hazards ratios (HRs) with corresponding 95% confidence intervals (CIs) of incident depression were reported for shift work and sleep patterns by Cox-proportional hazard models. The average follow-up time was 12.13±1.94 years and the incidence rate of depression was 2.95 (2.89-3.02) per 1000 person-years. After fully adjustment, the participants with irregular and permanent night shifts companied by any sleep pattern were significantly associated with increased risk of incident depression compared with no shift work companied by favorable sleep patterns. The females seemed to be more vulnerable when having night shifts and unfavorable sleep patterns compared with the males. The increased risk of incident depression associated with shift work regardless of night shifts and evening/weekend shifts was not able to offset by favorable sleep patterns. The workers with unhealthy sleep patterns, especially inappropriate sleep duration and insomnia companied by shift work schedule should be paid more attention considering higher risk of depression.

Abstract
PURPOSE Life stress has negative impacts on sleep and mental health. Little empirical work has investigated the associations between life stress, insomnia, and anxiety/depressive symptoms (ADS) in multi-wave longitudinal studies. This longitudinal study examined these associations in a large sample of adolescents. METHODS A total of 6995 adolescents (mean age = 14.86 years, 51.4 % male) participated in a 3-wave longitudinal study of behavior and health in Shandong, China. Standardized rating scales were used to assess life stress, insomnia, and ADS in 2015 (T1), 1 year later (T2), and 2 years later (T3). Three-wave longitudinal panel models were conducted to examine the prospective relationships between life stress, insomnia, and ADS. RESULTS The prevalence and persistence rates of insomnia and ADS across T1-T3 significantly increased with elevated life stress score (p < .001). Cross-lagged panel analysis showed that life stress, insomnia, and ADS at a later time point were significantly predicted by the same variable at earlier time points (all p < .01). Life stress, insomnia, and ADS significantly predicted each other bidirectionally over time (all p < .01). The relationship between life stress and ADS was partially mediated by insomnia. The relationship between life stress and insomnia was partially mediated by ADS. STUDY LIMITATION Life stress, insomnia, and ADS were all self-reports. CONCLUSIONS Life stress, insomnia, and ADS are prospectively bidirectionally related to one another. Insomnia was a mediator of life stress and subsequent ADS and vice versa. These findings underscore the importance of sleep and mental health assessment and intervention in adolescents following life stress.

Abstract
OBJECTIVE Family conflict is a risk factor for suicidal behaviors among adolescents. However, few longitudinal studies have investigated this association and explored the mediation effect of behavioral and emotional problems. This study aimed to examine the longitudinal association between family conflict, internalizing and externalizing problems, and suicidal behaviors in a large sample of Chinese adolescents. METHOD This longitudinal study of 7,072 adolescents was based on the Shandong Adolescent Behavior & Health Cohort (SABHC). Participants completed a self-administrated questionnaire to assess family conflict, internalizing and externalizing problems, suicidal behaviors, and family demographics at baseline. Excluding adolescents with any suicidal behavior at baseline (N = 839), others (N = 6,233) were allowed to report their internalizing and externalizing problems and suicidal behaviors one-year later. Path analyses were conducted to examine the mediation relationship of internalizing and externalizing problems between family conflict and suicidal behaviors. RESULTS Of 6,233 participants, mean age was 14.52 at baseline and 51.2% were males. Adolescents with subsequent suicidal behaviors reported higher scores in family conflict, internalizing and externalizing problems (Ps < 0.01). Path analyses showed that internalizing and externalizing problems played a significant mediating role in the associations of family conflict with suicidal behaviors after adjusting for covariates. CONCLUSIONS Family conflict is associated with suicidal behaviors in adolescents, which is partially mediated by internalizing and externalizing problems. Internalizing problems is the major mediator between family conflict and suicidal thought or suicide plan; however, internalizing and externalizing problems play similar mediating roles in the family conflict-suicide attempt link.

Abstract
The purpose of this study was to verify the mediating role of depressive symptoms between excessive daytime sleepiness and suicidal ideation in college students. Of the 6944 participants, 2609 (37.6%) were male and 4335 (62.4%) were female. College students with excessive daytime sleepiness (p < 0.001) and those with depressive symptoms (p < 0.001) were more likely to have suicidal ideation. Moreover, both excessive daytime sleepiness (β = 0.14, 95% CI: 1.01−1.32) and depressive symptoms (β = 1.47, 95% CI: 3.80−5.00) were associated with suicidal ideation. The effect size of the mediating role of depressive symptoms in excessive daytime sleepiness to suicidal ideation was 50.41% for the entire sample, 58.33% for males, and 42.98% for females. Depressive symptoms partially mediated the relationship between excessive daytime sleepiness and suicidal ideation. The timely assessment of depressive symptoms in college students with excessive daytime sleepiness, and intervention, may reduce their risk of suicidal ideation.

Abstract
BACKGROUND Longitudinal data on the associations between sleep disturbances, daytime sleepiness, and daily functioning are limited in the general adolescent population. This study examined the cross-sectional and longitudinal associations between insomnia, excessive daytime sleepiness (EDS), and subject-specific academic performance in a large sample of Chinese adolescents. METHOD Data were derived from the Shandong Adolescent Behavior and Health Cohort (n = 7,072) study. A self-administered questionnaire was used to assess insomnia, EDS, academic performance (overall, Chinese, mathematics, and English), behavioral and emotional problems, and family demographics. The cross-sectional analysis was conducted with baseline data while the longitudinal analysis was conducted with both baseline and 1-year follow-up data. Logistic regression analyses and mediation models were performed to examine the associations between insomnia, EDS, and academic performance. RESULTS Logistic regression analyses revealed that insomnia and EDS had significant cross-sectional associations with overall performance and mathematics performance after controlling for age, gender, ever smoking, ever alcohol drinking, frequent snore, sleep duration, chronic disease, anxious/depressive symptoms, parents' education, parents' occupation, and family economic status. Both insomnia (OR = 1.20, 95% CI: 1.00-1.45) and EDS (OR = 1.22, 95% CI: 1.03-1.45) at baseline were significantly associated with poor mathematics performance 1 year later. The effect of insomnia at baseline on poor academic performance 1 year later was mediated by EDS except for the Chinese subject after controlling for the covariates. CONCLUSIONS Insomnia and daytime sleepiness are significantly associated with poor academic performance, particularly in mathematics. EDS mediates the association between insomnia and poor academic performance. Further research is warranted to investigate the effects of sleep disturbance and daytime sleepiness on the learning process and performance across academic subjects.

Abstract
BACKGROUND There is limited evidence for the association among soft drink consumption, aggressive behaviors, and depressive symptoms among the adolescents. METHODS Data were derived from a national representative sample of Youth Risk Behavior Surveys of United States during 2011 to 2019. Binary logistic regression models with complex sampling design were used to estimate the effect of soft drink consumption on aggressive behaviors and depressive symptoms. Mediating analysis was used to explore the association between soft drink consumption and depressive symptoms by aggressive behaviors. FINDINGS The total prevalence of depressive symptoms was 3l.2 % (30.3 %-32.0 %). Compared with none of soft drink consumption, <1 time/day (OR: 1.29, 95%CI: 1.19-1.41), 1-2 times/day (OR: 1.49, 95%CI: 1.33-1.67), and ≥3 times/day (OR: 1.95, 95%CI: 1.70-2.24) were significantly associated with increased risk of aggressive behaviors. High levels of soft drink consumption (1-2 times/day, OR: 1.19, 95%CI: 1.07-1.32; ≥3 times/day, OR: 1.61, 95%CI: 1.42-1.81) and aggressive behaviors (OR: 1.98, 95%CI: 1.84-2.13) were found to be significantly associated with increased risk of depressive symptoms. A linear dose-response relationship of soft drink consumption with aggressive behaviors and depressive symptoms was found in this study (all p < 0.001). Aggressive behaviors partially mediated the association between soft drink consumption and depressive symptoms and each pathway was statistically significant. LIMITATIONS The causal relationship was not able to certain because of the cross-sectional design. CONCLUSIONS The mediating role of aggressive behaviors on the association of high levels of soft drink consumptions with depressive symptoms should be paid more attention among the adolescents.

Abstract
Abstract
Study Objectives
Insomnia symptoms, excessive daytime sleepiness (EDS), and suicidal behavior are prevalent among adolescents. Growing studies have shown that both insomnia symptoms and EDS are associated with suicidal behavior. However, little is known about the pathways between insomnia symptoms, EDS, and suicidal behavior. This study aimed to examine the longitudinal mediating effect of EDS on insomnia–suicidal behavior link in a large sample of Chinese adolescents.
Methods
Participants were 7,072 adolescents (Mean age=14.58 years, 50.0% males) who were surveyed at baseline and were followed up 1 year later in the Shandong Adolescent Behavior and Health Cohort study. A self-administered questionnaire was used to measure insomnia symptoms, daytime sleepiness, sleep duration, social jetlag, suicidal behavior, and adolescent and family demographics.
Results
The prevalence of insomnia symptoms and EDS at baseline were 14.3% and 21.1%, respectively. Adolescents with insomnia symptoms or EDS at baseline were more likely to report suicidal behavior at 1-year follow-up compared to adolescents without insomnia symptoms or EDS. Path analyses showed that EDS played a significant mediation role between insomnia symptoms and suicidal behavior (including any suicidal behavior, suicidal thought, suicide plan, and suicide attempt) before and after adjusting for adolescent and family factors, sleep duration, social jetlag, and prior suicidal behavior.
Conclusion
Insomnia symptoms and EDS were associated with increased risk of subsequent suicidal behavior. The association between insomnia symptoms and suicidal behavior was mediated by EDS. These findings highlight the importance of assessment and treatment of insomnia and daytime sleepiness for suicide prevention in adolescents.

Abstract
BACKGROUND Longitudinal evidence for sociodemographic and clinic factors deviating risk for suicide and repetition following SH (self-harm) varied greatly. METHODS A comprehensive search of PubMed, Web of Science, EMBASE, and PsycINFO was conducted from January 1st, 2010 to April 5th, 2022. Longitudinal studies focusing on examining associating factors for suicide and repetition following SH were included. PROSPERO registration CRD42021248695. FINDINGS The present meta-analysis synthesized data from 62 studies published from Jan. 1st, 2010. The associating factors of SH repetition included female gender (RR, 95%CI: 1.11, 1.04-1.18, I2=82.8%), the elderly (compared with adolescents and young adults, RR, 95%CI: 0.67, 0.52-0.87, I2=86.3%), multiple episodes of SH (RR, 95%CI: 1.97, 1.51-2.57, I2=94.3%), diagnosis (RR, 95%CI: 1.60, 1.27-2.02, I2=92.7%) and treatment (RR, 95%CI: 1.59, 1.40-1.80, I2=93.3%) of psychiatric disorder. Male gender (RR, 95%CI: 2.03, 1.80-2.28, I2=83.8%), middle-aged adults (compared with adolescents and young adults, RR, 95%CI: 2.40, 1.87-3.08, I2=74.4%), the elderly (compared with adolescents and young adults, RR, 95%CI: 4.38, 2.98-6.44, I2=76.8%), physical illness (RR, 95%CI: 1.95, 1.56-2.43, I2=0), multiple episodes of SH (RR, 95%CI: 2.02, 1.58-2.58, I2=87.4%), diagnosis (RR, 95%CI: 2.13, 1.67-2.71, I2=90.9%) and treatment (RR, 95%CI: 1.36, 1.16-1.58, I2=58.6%) of psychiatric disorder were associated with increased risk of suicide following SH. INTERPRETATION Due to the substantial heterogeneity for clinic factors of suicide and repetition following SH, these results need to be interpreted with caution. Clinics should pay more attention to the cases with SH repetition, especially with poor physical and psychiatric conditions.

Abstract
The isomer depletion of ^{93m}Mo was recently reported [Chiara et al., Nature (London) 554, 216 (2018)NATUAS0028-083610.1038/nature25483] as the first direct observation of nuclear excitation by electron capture (NEEC). However, the measured excitation probability of 1.0(3)% is far beyond the theoretical expectation. In order to understand the inconsistency between theory and experiment, we produce the ^{93m}Mo nuclei using the ^{12}C(^{86}Kr,5n) reaction at a beam energy of 559 MeV and transport the reaction residues to a detection station far away from the target area employing a secondary beam line. The isomer depletion is expected to occur during the slowdown process of the ions in the stopping material. In such a low γ-ray background environment, the signature of isomer depletion is not observed, and an upper limit of 2×10^{-5} is estimated for the excitation probability. This is consistent with the theoretical expectation. Our findings shed doubt on the previously reported NEEC phenomenon and highlight the necessity and feasibility of further experimental investigations for reexamining the isomer depletion under low γ-ray background.

Abstract
Previous suicide attempt is a strong risk factor for subsequent suicide and other causes of mortality, but evidence from China is sparse. In this study, follow up face-to-face interviews were conducted with suicide attempters or a key informant, and any subsequent deaths were examined through local cause-of-death censoring databases to ascertain details surrounding the death. Competitive risk models and Cox proportional hazard regression models were used to ascertain significant risk factors of suicide, non-suicide and overall deaths following suicide attempt. Predictive nomograms were also constructed to predict the probability of suicide, non-suicide, and overall deaths. A total of 1103 suicide attempters were successfully interviewed with an average follow-up time of 7.48 (7.38-7.57) years. The cumulative rates of suicide at 1, 2, 3, 5 and 10 years were 0.27%, 0.63%, 0.91%, 1.56%, and 1.83%, respectively. Factors significantly associated with subsequent suicide were advancing age, history of suicide attempt, and mental disorders. Significant risk factors for non-suicide death included males, advancing age, and physical illness. Overall deaths during the follow-up period were associated with males, advancing age, physical illness, and mental disorders. Predictive models showed good ability with satisfactory C-indexes (between 0.77 and 0.86) and excellent calibration performance in predicting the varying causes of subsequent death among suicide attempters in rural China.

Abstract
BACKGROUND Non-suicidal self-injury (NSSI) is a significant public health concern. Authoritarian parenting is a common parenting style in China. Authoritarian parenting is associated with NSSI in adolescents. Little is known about the mechanism underlying this association. This study was to investigate the mediating effect of depressive symptoms on the association between maternal authoritarian parenting and NSSI among Chinese adolescents. METHODS A total of 7072 adolescents who participated in the 1-year follow-up of Shandong Adolescent Behavior & Health Cohort (SABHC) were included for the analysis. A self-administered questionnaire was used to assess authoritarian parenting, depressive symptoms, non-suicidal self-injury, and family demographics in November-December in 2015. One year later, a follow-up survey was carried out to assess participants' depressive symptoms and NSSI. RESULTS Of the sample, mean age was 14.58 (SD = 1.46) and 3536 (50%) were female at baseline. 19.4% adolescents reported having ever NSSI over the past 12 months at baseline, and 8.8% reported having ever NSSI at 1-year follow-up. The association of maternal authoritarian parenting with subsequent NSSI was at least partially mediated by depressive symptoms. Mediation analyses showed that effect size was 0.194 in the entire sample, 0.192 in females and 0.193 in males, respectively. LIMITATION All variables were measured based on self-report. CONCLUSIONS Maternal authoritarian parenting style is a significant predictor of NSSI and its association with NSSI is partially mediated by depressive symptoms among Chinese adolescents. It may be important to intervene poor parenting styles and depression to reduce the risk of NSSI in Chinese adolescents.

Abstract
PURPOSE Nightmares are common, especially in pediatric populations and psychiatric patients. Nightmares are associated with daytime distress and negative health outcomes. The data on the prevalence and psychopathological profiles of nightmares in Chinese adolescents are limited. This study examined age and gender differences in nightmare frequency and associated psychopathological problems in a large sample of Chinese adolescents. METHODS A total of 11,831 adolescent students (mean age = 14.9, 12-18 years) participated in the baseline survey of Shandong Adolescent Behavior and Health Cohort. Participants completed a self-administered questionnaire to report their nightmare frequency, trait anger, hopelessness, and multiple domains of behavioral/emotional problems. Univariate and multivariate analyses were performed to examine psychopathological problems in relation to nightmare frequency. RESULTS Of the sample, 45.2% reported having nightmares at least once in the past month and 7.9% at least once/week. Girls reported more frequent nightmares than boys. Nightmare frequency significantly declined with age for both boys and girls. Mean scores on trait anger, hopelessness, attention, internalizing problems, and externalizing problems significantly increased with nightmare frequency. Frequent nightmares (at least once/week) were significantly associated with 2-4-fold increased likelihood of behavioral/emotional problems after adjusting for adolescent and family covariates. CONCLUSION Nightmares are prevalent in Chinese adolescents. Frequent nightmares are associated with multiple domains of psychopathological problems. Assessment and intervention of frequent nightmares should be incorporated into routine clinical practice and mental health services in adolescents.

Abstract
Background: The evidence is limited for the dose–response association between breakfast skipping and suicidality. The underlying pathway from breakfast skipping to suicidality has also rarely been explored in previous studies. Methods: The data of Youth Risk Behavior Surveys (YRBSs) of the United States from 2011 to 2019 were used with a sample size of 74,074. The male: female ratio was nearly 1:1. Binary logistic regression models with complex sampling design were adopted to show the effect of breakfast skipping on weight status, depressive symptoms, and suicidality. Serial mediation was used to explore the association between breakfast skipping and suicidality by overweight/obesity and depressive symptoms. Findings: The weighted prevalence rates (95% confidence interval) of suicidal ideation, suicide plan, suicide attempt, and medically serious suicide attempt for skipping breakfast totally (0 times/week) were 25.6% (24.4–26.8%), 21.7% (20.5–22.9%), 14.2% (13.0–15.3%), and 5.3% (4.6–5.9%). Breakfast skipping was significantly associated with increased risk of suicidal ideation, suicide plan, suicide attempt, and medically serious suicide attempt. There was statistical significance for the linear dose–response association between breakfast skipping and overweight/obesity, depressive symptoms, and suicidality regardless of sex and age. A serial mediation with effect sizes between 39.68% and 51.30% for the association between breakfast skipping and suicidality by overweight/obesity and depressive symptoms was found in this study. Conclusions: This study emphasizes the hazards of breakfast skipping, which could increase the risk of suicidality among adolescents. Overweight/obesity and depressive symptoms as the mediating factors for the association between breakfast skipping and suicidality should also be with more attention.

Abstract
AIMS Pain and depressive symptoms are prevalent in adolescents. Data on the association between pain and depressive symptoms in the general adolescent population are limited. The purpose of this study was to investigate the prospective associations of headache, stomachache, and other nonspecific pain with depressive symptoms in a large sample of Chinese adolescents. METHODS A total of 7072 adolescents who participated in the baseline survey and were followed up 1 year later were included in the prospective analysis. Participants completed a self-administered questionnaire to assess three types of pain (headache, stomachache, and other nonspecific pain) and demographics. Depressive symptoms were assessed by the Center for Epidemiology Studies Depression Scale. Logistic regression models were conducted to evaluate the associations between pain and depressive symptoms. RESULTS The prevalence and incidence rates of depressive symptoms significantly increased with elevated pain frequencies. After adjusting for insomnia symptoms and other adolescent and family covariates, frequent headache (OR=2.39, 95% CI =1.37-4.16) and other nonspecific pain (sometimes pain: OR=1.57, 95% CI =1.14-2.15; frequent pain: OR=2.78, 95% CI =1.33-5.82) were significantly associated with increased risk of depressive symptoms 1 year later. Study limitation: Pain and depressive symptoms were self-reports. CONCLUSIONS The findings suggest that frequent pain is associated with subsequent depressive symptoms. Further research is needed to determine the causal relationship between pain and depressive symptoms in adolescents.

Abstract
BACKGROUND Frequent nightmares are related to depressive symptoms in adolescents. Little is known about pathways from frequent nightmares to depressive symptoms. This study aimed to examine the mediation effect of nightmare distress in the association between frequent nightmares and depressive symptoms in a large sample of Chinese adolescents. METHODS A total of 11,831 adolescents who participated in the baseline survey of Shandong Adolescent Behavior and Health Cohort were included in the analysis. A self-administered questionnaire was used to measure nightmare frequency, nightmare distress, depressive symptoms, sleep duration, insomnia, and demographic characteristics. Linear regressions and mediation analyses were performed to examine the associations between frequent nightmares, nightmare distress and depressive symptoms. RESULTS Of 11,831 participates, 50.9% were males and the mean age was 14.97 ± 1.45. Adolescents with frequent nightmares scored significantly higher on nightmare distress (t = 29.87, P < 0.001) and depressive symptoms (t = 20.05, P < 0.001) than those adolescents without frequent nightmares. Frequent nightmares (β = 1.04, 95% CI: 0.48-1.60) and nightmare distress (β = 0.30, 95% CI: 0.28-0.32) were associated with depressive symptoms. Mediation analyses showed that nightmare distress accounted for 63.76% of the total effects in the entire sample, 51.17% in males and 80.00% in females, respectively. LIMITATION No causality could be made from the cross-sectional data and possible information bias due to self-report. CONCLUSIONS The association between frequent nightmares and depressive symptoms appears to be substantially mediated by nightmare distress. Assessing and intervening distress associated with frequent nightmares may have important clinical implications for reducing the risk of depression in adolescents.

Abstract
BACKGROUND Research on predictors and risk of recurrence after suicide attempt from China is lacking. This study aims to identify risk factors and develop prediction models for recurrent suicidal behavior among suicide attempters using Cox proportional hazard (CPH) and machine learning methods. METHODS The prospective cohort study included 1103 suicide attempters with a maximum follow-up of 10 years from rural China. Baseline characteristics, collected by face-to-face interviews at least 1 month later after index suicide attempt, were used to predict recurrent suicidal behavior. CPH and 3 machine learning algorithms, namely, the least absolute shrinkage and selection operator, random survival forest, and gradient boosting decision tree, were used to construct prediction models. Model performance was accessed by concordance index (C-index) and the time-dependent area under the receiver operating characteristic curve (AUC) value for discrimination, and time-dependent calibration curve along with Brier score for calibration. RESULTS The median follow-up time was 7.79 years, and 49 suicide attempters had recurrent suicidal behavior during the study period. Four models achieved comparably good discrimination and calibration performance, with all C-indexes larger than 0.70, AUC values larger than 0.65, and Brier scores smaller than 0.06. Mental disorder emerged as the most important predictor across all four models. Suicide attempters with mental disorders had a 3 times higher risk of recurrence than those without. History of suicide attempt (HR = 2.84, 95% CI: 1.34-6.02), unstable marital status (HR = 2.81, 95% CI: 1.38-5.71), and older age (HR = 1.51, 95% CI: 1.14-2.01) were also identified as independent predictors of recurrent suicidal behavior by CPH model. CONCLUSIONS We developed four models to predict recurrent suicidal behavior with comparable good prediction performance. Our findings potentially provided benefits in screening vulnerable individuals on a more precise scale.

Abstract
OBJECTIVE Emerging evidence suggests that vitamin D might protect from attempted suicide. The study aimed to investigate the associations between single-nucleotide polymorphisms (SNPs) related to vitamin D levels identified in a large genome-wide association study and attempted suicide in rural China. METHODS This 1:1 matched case-control study included altogether 510 suicide attempters and 510 community controls. Genotypes of four target SNPs (DHCR7-rs12785878, CYP2R1-rs10741657, GC-rs2282679, and CYP24A1-rs6013897) were determined, and a genetic risk score (GRS) was constructed to evaluate the combined effect of them. Demographic and psychological information was acquired through face-to-face interviews. RESULTS The A allele of CYP24A1-rs6013897 was significantly associated with attempted suicide (OR = 1.27, 95% CI, 1.03-1.58, P = 0.029), even after adjusting for demographic and psychological confounders (adjusted OR = 1.53, 95% CI, 1.01-2.30, P = 0.043). The GRS analyses revealed a significantly higher risk of attempted suicide with a greater number of low vitamin D alleles (adjusted OR = 1.33, 95% CI, 1.13-1.58, P < 0.001). Subgroup analyses stratified by sex indicated that the genetic associations were only significant among males with adjusted ORs of 3.77 (95% CI, 1.56-9.10) for the A allele of rs6013897 and 2.04 (95% CI, 1.32-3.17) for GRS. CONCLUSIONS Our findings identity CYP24A1-rs6013897 as a potential biomarker for attempted suicide and indicate that a genetic predisposition to lower vitamin D levels may contribute to attempted suicide. It suggests the possibility that vitamin D may have the preventive potential for attempted suicide.

Abstract
Objective: To explore the relationship between family conflict and adolescent future suicidal behavior. Methods: A total of 7 072 adolescents who participated in the baseline survey and the first follow-up survey of Shandong Adolescent Behavior and Health Cohort were included in the analysis. They were sampled from 8 middle schools in 3 counties of Shandong province, China. A self-reported questionnaire was used to measure suicidal behavior, family conflict, depression, and demographic characteristics. Logistic regression model was used to analyze the relationship between family conflict and suicidal behavior. Results: In the baseline survey, the age of 7 072 subjects was (14.58±1.45) years, and boys and girls accounted for 50.0% respectively. 750 people (10.6%) had any suicidal behavior, of which 707 (10.0%), 258 (3.6%) and 190 (2.7%) had suicidal ideation, suicide planning and suicide attempt, respectively. The family conflict scores of the suicidal group were higher than those of the non-suicidal group. After adjusting for covariates, logistic regressions showed that family conflict was associated with increased risk of suicidal behavior (OR=1.05, 95%CI: 1.01-1.10), suicidal ideation (OR=1.05, 95%CI: 1.00-1.09), suicide planning (OR=1.08, 95%CI: 1.01-1.16) and suicide attempt (OR=1.10, 95%CI: 1.02-1.19). Further stratified by gender, results showed no significant association between family conflict and suicidal behavior in girls; the association of family conflict with suicidal behavior was more significant in boys, especially for suicidal ideation and suicide planning, and the OR value of the latter was higher than the former. The results were stable after sensitivity analysis in males. Conclusions: Family conflict might increase the risk of adolescent suicidal behavior, especially in males. Harmonious family environment and good family atmosphere are of great significance to adolescent suicide prevention and control.

Abstract
PURPOSE Self-harm in adolescents is prevalent and is the most significant predictor of future self-harm and suicide. Longitudinal data on the incidence and predictors of repeat self-harm in the general population of adolescents are limited. This study investigated 1-year incidence and psychosocial predictors of repeat self-harm in Chinese adolescents. METHODS Shandong Adolescent Behavior and Health Cohort is a longitudinal study of behavior and health in adolescents in Shandong Province, China. Of 7072 participants who were assessed in 2015 and again 1 year later in 2016, 1879 reported a history of self-harm at the baseline survey and were included for this analysis. A self-administered structured questionnaire was used to assess behavioral and emotional problems, sleep, life stress, previous history of self-harm and suicidal thought, and family factors at baseline and self-harm at 1-year follow-up. RESULTS Mean age of the sample was 14.86 (SD 1.36) years and 54.6% were female. At 1-year follow-up, 22.1% participants engaged in repeat self-harm. Multiple logistic regression analyses showed that female gender (OR 1.45, 95% CI 1.11-1.89), alcohol use (OR 1.95, 95% CI 1.48-2.57), frequent nightmares (OR 1.61, 95% CI 1.14-2.28), elevated depression score (OR 1.59, 95% CI 1.05-2.42), and prior suicidal thought (OR 1.79, 95% CI 1.37-2.34) were independently and significantly associated with an increased risk of repeat self-harm. CONCLUSION More than one in five Chinese adolescents who had a history of self-harm engaged in self-harm at 1-year follow-up. Multiple psychosocial factors including female gender, alcohol use, frequent nightmares, depression, and prior suicidal thought appeared to be significant predictors of repeat self-harm. Our findings highlight the importance of comprehensive psychosocial assessment and intervention of repeat self-harm in adolescents.

BACKGROUND Little is known about the prospective association between sleep disordered breathing (SDB) and depressive symptoms in Chinese adolescents. This study examined the independent predictive role of SDB symptoms in depressive symptoms in a large sample of adolescents. METHODS A total of 11831 adolescents who participated in the baseline survey of Shandong Adolescent Behavior and Health Cohort and 7072 adolescents who were resurveyed 1 year later were included for the analyses. Adolescents completed a self-administered questionnaire about demographics, mental health, sleep problems, and family environment. SDB symptoms were assessed by 3 items about loud snoring, breathing pauses, and snorting/gasping. The Chinese Youth Self-Report anxious/depressed subscale was used to assess depressive symptoms. RESULTS In the cross-sectional analyses, 11.8% adolescents had depressive symptoms, and elevated frequency of SDB symptoms were significantly associated with depressive symptoms. In the longitudinal study, 4.5% of adolescents had persistent depressive symptoms, the incidence rate of depressive symptoms at 1-year follow-up was 6.5%, and elevated frequency of any SDB symptoms (often: OR=2.23, 95%CI:1.50-3.32) at baseline was significantly associated with incident depressive symptoms after adjusting for potential confounders. The associations between SDB symptoms and depressive symptoms were similar for boys and girls. LIMITATION SDB symptoms and depressive symptoms were measured by self-report. CONCLUSION SDB symptoms are an independent and significant predictor of depressive symptoms in adolescents. Further research is needed to understand the biological mechanisms between SDB and mood dysregulation in adolescents.

Abstract
Background Rapid urbanization, academic pressures, and developmental life transition stressors contribute to mental health stress for postsecondary students in China. Effective prevention, early identification, and timely intervention are challenged by stigma, a lack of mental health literacy, and inadequate mental health resources. Objective Our implementation science (IS) research project is aimed at evaluating the use of an evidence-informed mental health promotion intervention named Acceptance and Commitment to Empowerment – Linking Youth and ‘Xin’ (hearts) (ACE-LYNX) to promote university student mental health in Jinan, China. Methods We will engage and collaborate with Shandong Mental Health Center, the provincial mental health center, and six local universities in different regions of Jinan. The ACE-LYNX intervention aims to reduce social stigma against mental illness, enhance mental health literacy, and improve access to quality mental health care by increasing interdisciplinary collaboration and forming a mental health network. It is based on two evidence-based approaches, Acceptance and Commitment Therapy (ACT) and Group Empowerment Psychoeducation (GEP), and it will be delivered through online learning and in-person group training. The project will train 90 interdisciplinary professionals using the model. They will in turn train 15 professionals and 20 students at each university. The project will adopt the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework, which provides a structure to examine the process and outcomes of implementation using mixed methods comprising quantitative and qualitative approaches along five dimensions: reach, efficacy, adoption, implementation, and maintenance. Results Over the course of the project, 720 champions will be directly trained. They will contribute to developing a formal and informal mental health network, strengthened by student-led mental health initiatives and professional-led initiatives to promote collaborative care and facilitated care pathways. We anticipate that our project will reach out to 11,000 to 18,000 students. Conclusions This IS protocol will outline our unique intervention model and key steps to contextualize, implement, and evaluate community-based mental health intervention.

Abstract
Background The relationship between impulsivity and suicide is inconsistent in different populations. Hence, the relationship between impulsivity and suicide still needs to be studied among the elderly population. The present study intends to explore the relationship between impulsivity and suicide among the rural Chinese elderly. Methods A case-control psychological autopsy study was conducted from February 1, 2014 to December 18, 2015 among rural residents over the age of 60 who died by suicide. The sample consisted of 242 suicides as the case group and 242 living individuals as the control group. Data on demographic characteristics, impulsivity, previous history of suicide attempts, social support, negative life events, and suicidal behavior were collected. Results Our study found that impulsivity increased the risk of suicide. The case group showed a higher Barratt Impulsiveness Scale score compared with the control group (p < 0.001), which indicates that impulsivity was higher among the elderly suicides. In addition, regression analyses show that impulsivity (odds ratio: 1.03, 95% confidence interval: 1.01–1.06) is an independent risk factor of suicide, after controlling for the effects of marital status, education, family annual income, being left behind, social support, and negative life events. Finally, compared with elderly who do not have a history of attempted suicide, elderly with a history of attempted suicide showed higher impulsivity (p = 0.001).

Abstract
Chronic pain and suicidal behavior are prevalent in adolescents. This longitudinal study examined the associations between pain symptoms and suicidal behavior in adolescents. A total of 7,072 adolescents participated in a follow-up study of behavior and health in Shandong, China. A self-administered structured questionnaire was used to assess pain symptoms (headache, stomachache, and other nonspecific pain), insomnia, anxiety/depression, substance use, stressful life events, prior suicidal behavior, and family environment in November-December in 2015. One year later, a follow-up survey was conducted. Mean age of the sample was 14.6 years, and half were female. Of the sample, 44.8% and 8.4% reported having one or more pain symptoms "sometimes" and "often", respectively. A total of 22.4% and 10.6% reported having lifetime suicidal behavior at baseline and subsequent suicidal behavior over the 1-year follow-up, respectively. Frequent pain was significantly associated with increased risk of suicidal behavior at baseline (OR=1.64, 95%CI=1.32-2.03) and during the subsequent year (OR=1.50, 95%CI=1.17-1.93) while adjusting for adolescent individual and family covariates. Among adolescents without a history of prior suicidal behavior, frequent pain was significantly associated with an approximately 70% increased risk of incident suicidal behavior (OR= 1.69, 95%CI=1.14-2.51). In conclusion, frequent pain appears to be predictive of adolescent suicidal behavior one year later. PERSPECTIVE: This article presents the prospective associations of frequent pain symptoms with suicidal behavior in adolescents. Frequent pain was associated with a 50-70% increased risk of suicidal behavior 1 year later. The finding underscores the importance of pain assessment and treatment in comprehensive suicide prevention efforts in adolescents.

Abstract
STUDY OBJECTIVES Pain symptoms, sleep disturbance, and daytime sleepiness are common in adolescents. This study examined the cross-sectional and prospective associations between pain symptoms and excessive daytime sleepiness (EDS) in a large sample of adolescents. METHODS Participants were 7,072 adolescents (mean age = 14.6 years) in a follow-up study of behavior and health in Shandong, China. A self-administered structured questionnaire was used to assess pain symptoms (headache, stomachache, and other general pain), body weight and height, sleep, anxiety/depression, substance use, and family environment in November-December in 2015 and one year later. The Chinese adolescent daytime sleepiness scale (CADSS) was used to measure daytime sleepiness. RESULTS Of the sample, 19.8% and 23.2% had moderate or severe EDS at baseline and at 1-year follow-up, respectively. The prevalence and 1-year incidence rates of EDS significantly increased with the frequencies of pain symptoms. Frequent pain was significantly associated with increased risk of EDS at baseline (OR=2.01, 95% CI=1.56-2.59), incident EDS (OR=1.41, 95% CI=1.03-1.93), and persistent EDS (OR=2.17, 95% CI=1.52-3.09) while adjusting for adolescent and family covariates, including anxiety/depression, nocturnal sleep duration, insomnia symptoms, frequent snoring, body mass index, and hypnotic use. Similar associations were observed across headache, stomachache, and other pain. CONCLUSIONS Frequent pain is significantly and independently associated with increased risk of EDS. Our findings suggest that assessing and treating pain symptoms is important to improve healthy sleep and reduce risk of EDS in adolescents. Further research is needed to understand the underlying psychological and neurobiological mechanisms between pain and daytime sleepiness in adolescents.

Abstract
Background Chinese students are extremely vulnerable to developing mental illness. The stigma associated with mental illness presents a barrier to seeking help for their mental health. Objective The Linking Hearts—Linking Youth and ‘Xin’ (hearts) project is an implementation science project that seeks to reduce mental illness stigma and promote the mental health of university students in Jinan, China. The Linking Hearts project consists of 3 components. In this paper, we outline the protocol for the first component, that is, the contextual assessment and analysis of the mental health needs of university students as the first step to inform the adaptation of an evidence-based intervention to be implemented in Jinan, China. Methods Six local universities will participate in the Linking Hearts project. A total of 100 students from each university (n=600) will engage in the contextual assessment through self-report surveys on depression, anxiety, stress, mental health knowledge, and mental health stigma. Quantitative data will be analyzed using several descriptive and inferential analyses via SPSS. A small number of participants (144 students and 144 service providers) will also be engaged in focus groups to assess the socio-environmental contexts of university students’ health and availability of mental health resources. Qualitative data will be transcribed verbatim and NVivo will be used for data management. Social network analysis will also be performed using EgoNet. Results Linking Hearts was funded in January 2018 for 5 years. The protocol of Linking Hearts and its 3 components was approved by the research ethics boards of all participating institutions in China in November 2018. Canadian institutions that gave approval were Ryerson University (REB2018-455) in January 2019, University of Alberta (Pro00089364), York University (e2019-162) in May 2019, and University of Toronto (RIS37724) in August 2019. Data collection took place upon ethics approval and was completed in January 2020. A total of 600 students were surveyed. An additional 147 students and 138 service providers took part in focus groups. Data analysis is ongoing. Results will be published in 2021. Conclusions Findings from this contextual assessment and analysis will generate new knowledge on university students’ mental health status, mental health knowledge, and resources available for them. These findings will be used to adapt and refine the Acceptance and Commitment to Empowerment-Linking Youth N’ Xin intervention model. The results of this contextual assessment will be used to inform the adaptation and refinement of the mental health intervention to promote the mental health of Chinese university students in Jinan.

Abstract
OBJECTIVES This study aimed to examine the bidirectional associations between handgrip strength and depressive symptoms in a nationally representative sample. DESIGN Cohort study with a 4-year follow-up. SETTING AND PARTICIPANTS A total of 13,208 participants from the China Health and Retirement Longitudinal Study were included in the analyses. METHODS Depressive symptoms were assessed using the 10-item Center for Epidemiological Studies-Depression Scale. Separate generalized estimating equations were used to analyze the cross-sectional and longitudinal associations between handgrip strength and depressive symptoms. Restricted cubic spline models were performed to explore the shape of the dose-response relationship. RESULTS Decreased handgrip strength was related to subsequent increased risk of depressive symptoms, such that participants in the lowest quartile of handgrip strength were found to have an approximately 36% increased in their risk of depressive symptoms compared with those in the highest quartile [odds ratio (OR) 1.36, 95% confidence interval (CI) 1.17, 1.58]. There was a linear dose-response relationship between handgrip strength and risk of depressive symptoms (Pnonlinearity = .25), in that a 5-unit increment in handgrip strength may lead to an 11% decrease in the risk of depressive symptoms (OR 0.89, 95% CI 0.85, 0.92). Conversely, depressive symptoms were prospectively associated with subsequent decreased handgrip strength (β = -0.84, 95% CI -1.13, -0.55). An approximatively L-shaped dose-response pattern was found for the association between depressive symptoms level and handgrip strength (Pnonlinearity = .02). CONCLUSIONS AND IMPLICATIONS The present study identified bidirectional associations between handgrip strength and depressive symptoms, and the associations were found to have a dose-response pattern. It provides important insights into integrated mental and physical health intervention strategies that simultaneously promote handgrip strength and depressive symptoms.

Abstract
STUDY OBJECTIVES Nightmares are a significant risk factor of suicidal behavior. This study examined the longitudinal associations of nightmare frequency and distress with suicidal thought (ST), suicide plan (SP), and suicide attempt (SA) and mediating role of depressive symptoms in adolescents. METHODS A total of 6,923 adolescents who participated in the 1-year follow-up of Shandong Adolescent Behavior & Health Cohort were included for the analysis. Participants completed a self-administered questionnaire to assess nightmares, sleep duration, insomnia, depressive symptoms, substance use, prior suicidal behavior, and family demographics in November-December in 2015. One year later, a follow-up survey was conducted to ask participants to report their depressive symptoms and suicidal behaviors. RESULTS Of the sample, 26.2% reported having frequent nightmares (at least twice/month) at baseline, and 10.0%, 3.6%, and 2.7% reported having ST, SP, and SA over 1-year follow-up. The rates of subsequent ST, SP, and SA all significantly increased with baseline nightmare frequency and distress. Path analyses showed that depressive symptoms played a significant mediating role in the associations of frequent nightmares and elevated nightmare distress with ST, SP, and SA before and after adjusting for adolescent and family covariates and prior suicidal behavior. CONCLUSIONS Suicidal risk increased with nightmare frequency and distress among adolescents. The association between nightmares and suicidal behavior was at least partially mediated by depressive symptoms. Assessing and intervening nightmares and depressive symptoms associated with nightmares may have important implications for preventing adolescent suicidal behavior.

Abstract
BACKGROUND There is a need to understand the psychological characteristics of suicide attempters to prevent future suicide attempts. This study aims to examine potential differences between individuals who have attempted suicide and those who have not done so, on several risk and protective measures. METHOD Participants were 11,806 undergraduate students from seven provinces in China, of which 237 reported a non-fatal suicide attempt. We used the random numbers generator function within the SPSS to randomly select a control subset of 1185 participants to be used as the comparison group based on a 1:5 case-control ratio. Scores on three commonly used risk measures (depression, hopelessness, and psychache) and three protective measures (social support, self-esteem, and purpose in life) for suicidality were adopted to compare the responses of the two groups. RESULTS Suicide attempters had indicated higher Median scores for all three risk factor measurements. Suicide attempters also reported significantly lower Median scores for all three protective factor measurements compared to non-suicide attempters. The results suggest that the suicide attempters' group had higher risks of suicidality compared to the non-attempter group. CONCLUSIONS Suicide attempters continued to report higher scores of risk factors and lower scores of protective factors, indicating that they may continue to be at a higher likelihood of a suicide attempt. Key protective factors should be identified for each individual in order to deliver appropriate clinical interventions to reduce their risk of reattempting.

Abstract
BACKGROUND The Nightmare Distress Questionnaire (NDQ) is the most common scale used to measure nightmare distress for its satisfactory psychometric properties. This study assessed the psychometric properties of the Chinese version of NDQ (NDQ-CV) in a large sample of adolescents. METHODS The NDQ-CV consists of 14 items (12 original NDQ items, 1 modified NDQ item and 1 new item) to assess waking distress associated with nightmares. Each item is rated on a 5-point scale from 1 = Never to 5 = Always. Subjects used for psychometric assessment of the NDQ-CV were 11,831 participants of the Shandong Adolescent Behavior and Health Cohort in China. Participants completed the NDQ-CV and a structured questionnaire to assess nightmare frequency, sleep, anxiety/depression, and academic performance. RESULTS The NDQ-CV score ranged from 14 to 70 (M = 22.5, SD = 8.7). Internal consistency reliability coefficient was 0.90. Both exploratory and confirmatory factor analyses yielded 2 dominant factors defined as nightmare general distress (10 items) and daytime reality perception (4 items). The NDQ-CV score was significantly correlated with short nocturnal sleep duration, anxiety/depression, insomnia, daytime sleepiness, and poor academic performance. Furthermore, NDQ-CV significantly predicted depressive symptoms 1 year later. STUDY LIMITATIONS All data were self-reported. CONCLUSIONS The NDQ-CV appears to be a simple, reliable, and valid scale for assessing nightmare distresses in Chinese adolescents. Further studies are warranted to test the reliability and validity of the NDQ-CV with adult samples.

Abstract
Background: Late-life suicide is a severe public health problem in rural China; however, knowledge regarding the specific characteristics and risk factors for completed suicide via violent and non-violent methods among elderly individuals in rural China is limited. Methods: Subjects aged 60 years or older were selected from rural areas in Shandong, Hunan, and Guangxi provinces in China. This study was a 1:1 matched case-control design conducted by using the psychological autopsy method. Results: According to the univariate analyses, the presence of mental disorder, higher degree of depression, loneliness, lack of social support, hopelessness, impulsivity, and increased quantity of life events were associated with suicide in both violent and non-violent methods. For violent suicide, another risk factor was the lack of pesticides at home. For non-violent suicide, other risk factors were not currently married, family suicide history, and alcohol use disorder (P < 0.05). Variables that remained in the logistic regression model were the severity of depressive symptoms for both violent and non-violent suicide. For non-violent suicide, the degree of hopelessness was another independent risk factor. In addition, violent suicides were more likely to lack pesticides at home, choose the spring season and have an increased quantity of life events than those who died by suicide via non-violent methods. Conclusion: The major risk factor for both violent and non-violent suicide was the severity of depressive symptoms. Suicide prevention measures that focus on depression among this vulnerable population are urgently needed. Moreover, the characteristics of suicides via violent methods differed from those via non-violent methods among elderly individuals. Suicide prevention efforts should be tailored to the specific characteristics of the different suicide methods utilized by older adults in rural areas.

Abstract
BACKGROUND Excessive digital media use is prevalent and has a negative impact on sleep, daytime functioning, and mental health in adolescents. We examined the prospective associations between digital media use and subsequent suicidal and non-suicidal self-harm. METHODS Shandong Adolescent Behavior & Health Cohort (SABHC) is a longitudinal study of adolescent behavior and health in Shandong, China. Participants included for the analysis were 7,072 SABHC adolescents who were initially assessed in 2015 and were reassessed in 2016. A self-administered structured questionnaire was used to measure digital media use (i.e., television watching, internet use, and mobile phone use) on weekdays and at the weekend, mental health, and self-harm. RESULTS Multivariable logistic regression analyses showed that daily internet use ≥2 h on weekdays (odd ratio (OR) = 1.86, 95% confidence interval(CI) = 1.25-2.76) and ≥3 h at the weekend (OR = 1.46, 95%CI = 1.06-2.00) and daily mobile phone use 2-3 h (OR = 1.46, 95%CI = 1.02-2.10) and ≥4 h (OR = 1.74, 95%CI = 1.20-2.51) at the weekend were significantly associated with increased risk of recurrent self-harm. Daily internet use ≥ 2 h on weekdays (OR = 1.81, 95%CI = 1.20-2.74) and ≥3 h at the weekend (OR = 1.55, 95%CI = 1.12-2.15), daily mobile phone use 1-2 h on weekdays (OR = 1.47, 95%CI = 1.02-2.12) and 2-3 h (OR = 1.49, 95%CI = 1.01-2.19) and ≥4 h (OR = 1.93, 95%CI = 1.31-2.85) at the weekend were significantly associated with increased risk of recurrent non-suicidal self-injury. Daily internet use 1-2 h on weekdays and 2-3 h at the weekend were significantly associated with increased risk of new suicide attempt (OR = 1.80, 95%CI = 1.07- 3.03) and recurrent suicide attempt (OR = 6.26, 95%CI = 1.31-29.88), respectively. LIMITATIONS All data were self-reported. CONCLUSIONS Excessive use of internet or mobile phone appears to be a significant risk factor of self-harm, suggesting that limiting adolescent use of internet and mobile phone may be beneficial to reduce risk of self-harm.

Abstract
BACKGROUND Frequent nightmares and depression are associated with non-suicidal self-injury (NSSI) in adolescents. Little is known about the mediating role of depression in the nightmare-NSSI link. This study explores the longitudinal mediating effect of depression on the relationship between frequent nightmares and NSSI as well as the moderating effect of gender using a three-wave longitudinal design. METHODS Participants were adolescents from the Shandong Adolescent Behavior and Health Cohort who were surveyed at baseline, 1 year later, and 2 years later. A self-administered questionnaire was used to measure nightmare frequency, depression, and NSSI. Structural equation modeling and multiple-group analysis were used to test the mediating effect of depression and the moderating effect of gender. Covariates included demographics and earlier measures of depression and NSSI. RESULTS Among 6995 participants, 3399 (48.6%) were females, mean age was 14.86 (SD = 1.50) years at baseline. Frequent nightmares had a significant mediation effect on NSSI through depression (Bab = 0.06, 95% CI = 0.02-0.10) after controlling for demographics and earlier measures of depression and NSSI. Gender had no significant moderating effect on the nightmare-NSSI association. LIMITATIONS All data were collected by self-report. CONCLUSIONS The association between frequent nightmares and NSSI in adolescents was partially mediated by depression. Frequent nightmares and depression should be assessed and treated to prevent self-harm in adolescents.

Abstract
Background It is unclear whether bisphosphonates are associated with risk of cancers. Therefore, this meta-analysis aimed to evaluate the effect of bisphosphonates on overall cancers. Methods A search in Pubmed, Embase, Cochrane Library and Web of Science databases was conducted, from the inception date of each resource to September 26, 2019. The summarised effect estimates with 95% CIs were calculated using a random-effect model. Heterogeneity and publication bias were explored. Results Thirty-four articles were included in this study (4,508,261 participants; 403,196 cases). The results revealed that bisphosphonates significantly decreased the risk of colorectal cancer (RR = 0.89, 95% CI: 0.81–0.98), breast cancer (RR = 0.87, 95% CI: 0.82–0.93) and endometrial cancer (RR = 0.75, 95% CI: 0.61–0.94), but no significant association was observed in all-cause cancer. Furthermore, nitrogen-containing bisphosphonates only had protective effects both on breast cancer (RR = 0.94, 95% CI: 0.90–0.99) and endometrial cancer (RR = 0.70, 95% CI: 0.54–0.92). Non-nitrogen-containing bisphosphonates tended to increase the risk of liver cancer (RR = 2.14, 95% CI: 1.23–3.72) and pancreas cancer (RR = 1.75, 95% CI: 1.32–2.33). Conclusion Bisphosphonates are significantly associated with risk reduction of colorectal, breast and endometrial cancer, especially nitrogen-containing bisphosphonates. It should be noted that non-nitrogen-containing bisphosphonates might increase the risk of liver and pancreas cancer. Large prospective cohort studies are needed to find the causal association between bisphosphonates and risk of cancers.

Abstract
OBJECTIVES This study aimed to examine the relationship between frailty markers and socioeconomic status (SES) to incidence of depressive symptoms using a nationally representative sample of middle-age and older adults. DESIGN Cohort study with a 4-year follow-up; 89.1% of the participants were followed for 2 years and 73.4% for 4 years. SETTING AND PARTICIPANTS A total of 6641 participants from the China Health and Retirement Longitudinal Study (CHARLS) were included in the analyses. METHODS The outcome was incident depressive symptoms. Educational level and occupational status were used to assess SES. Physical frailty status was evaluated using 2 frailty markers, namely weakness and slowness. Two-item questionnaire was used to assess social frailty. Cox regression models were used to examine the relationship between frailty markers and SES to incidence of depressive symptoms, with sociodemographic characteristics, lifestyle information, self-rated health status, medical histories, and depressive symptoms score at baseline adjusted. RESULTS Infrequent social activity [hazard ratio (HR) 1.09, 95% confidence interval (CI) 1.00‒1.19], weakness (HR 1.15, 95% CI 1.03‒1.28), and slowness (HR 1.19, 95% CI 1.01‒1.41) were associated with incidence of depressive symptoms. SES was associated with depressive symptoms not only through social frailty (β = 0.01, 95% CI 0.002‒0.011) and physical frailty (β = 0.01, 95% CI 0.001‒0.012) separately but also through social frailty and physical frailty sequentially. Furthermore, the effect of weakness and slowness on depressive symptoms occurred in participants with lower educational level and doing agricultural work, while the effect of infrequent social activity occurred in participants with higher educational level and doing nonagricultural work. CONCLUSIONS/IMPLICATIONS SES is associated with depressive symptoms, in which frailty partly mediates the association. The effect of frailty on depressive symptoms varied across SES. Integrated and comprehensive intervention strategies, including assessing socioeconomic circumstances as well as improving frailty, are suggested in prevention of depressive symptoms.

Abstract
BACKGROUND Deliberate self-harm (DSH) is often recurrent, but the reported rate of short-term repetition of DSH has varied greatly. This systematic review and meta-analysis aim to synthesize findings through providing pooled rate estimates and to explore their differences by age, gender, and other factors. METHODS A comprehensive search of PubMed, Web of Science, EMBASE, and PsycINFO was conducted to include longitudinal studies from 1999 to 2018. Random effects model was applied to pool rates of non-fatal and fatal repetition at 0.5, 1, 2, and 3 years intervals. RESULTS Of 9201 potentially eligible articles 76 studies were included for this systematic review and meta-analysis. The pooled rates of non-fatal repetition were 15.01%, 17.03%, 20.82%, and 24.20% during the 0.5-year, 1-year, 2-year, and 3-year follow-up, respectively. The corresponding rates of fatal repetition were 0.77%, 1.34%, 1.49% and 2.46%, respectively. When focusing on the 1-year follow-up, the pooled rate of fatal, not non-fatal, repetition was significantly higher in males than females. The rate of non-fatal DSH repetition was highest in middle-aged adults, while the rate of fatal repetition was highest among the elderly. Geographically, Europe had higher rate of non-fatal repetition whilst Asia had higher rate of repetition leading to death. LIMITATION Search was limited to English language and publication bias was observed. CONCLUSIONS Both non-fatal and fatal repetitions are common among people with DSH, but the rates differ considerably by gender, age and geographical location. These insights may guide provision of follow-up care and effort of suicide prevention for this high-risk population.
