Obesity and lipid indices as predictors of depressive symptoms in middle-aged and elderly Chinese: insights from a nationwide cohort study

BackgroundDepressive symptoms are one of the most common psychiatric disorders, with a high lifetime prevalence rate among middle-aged and elderly Chinese. Obesity may be one of the risk factors for depressive symptoms, but there is currently no consensus on this view. Therefore, we investigate the relationship and predictive ability of 13 obesity- and lipid-related indices with depressive symptoms among middle-aged and elderly Chinese.MethodsThe data were obtained from The China Health and Retirement Longitudinal Study (CHARLS). Our analysis includes individuals who did not have depressive symptoms at the baseline of the CHARLS Wave 2011 study and were successfully follow-up in 2013 and 2015. Finally, 3790 participants were included in the short-term (from 2011 to 2013), and 3660 participants were included in the long-term (from 2011 to 2015). The average age of participants in short-term and long-term was 58.47 years and 57.88 years. The anthropometric indicators used in this analysis included non-invasive [e.g. waist circumference (WC), body mass index (BMI), and a body mass index (ABSI)], and invasive anthropometric indicators [e.g. lipid accumulation product (LAP), triglyceride glucose index (TyG index), and its-related indices (e.g. TyG-BMI, and TyG-WC)]. Receiver operating characteristic (ROC) analysis was used to examine the predictive ability of various indicators for depressive symptoms. The association of depressive symptoms with various indicators was calculated using binary logistic regression.ResultsThe overall incidence of depressive symptoms was 20.79% in the short-term and 27.43% in the long-term. In males, WC [AUC = 0.452], LAP [AUC = 0.450], and TyG-WC [AUC = 0.451] were weak predictors of depressive symptoms during the short-term (P < 0.05). In females, BMI [AUC = 0.468], LAP [AUC = 0.468], and TyG index [AUC = 0.466] were weak predictors of depressive symptoms during the long-term (P < 0.05). However, ABSI cannot predict depressive symptoms in males and females during both periods (P > 0.05).ConclusionThe research indicates that in the middle-aged and elderly Chinese, most obesity- and lipid-related indices have statistical significance in predicting depressive symptoms, but the accuracy of these indicators in prediction is relatively low and may not be practical predictors.

A cross-sectional mental-health survey of Chinese postgraduate students majoring in stomatology post COVID-19 restrictions

BackgroundThe psychological status of Chinese postgraduate students majoring in stomatology after the COVID-19 restrictions still remains unclear. The objective of this study is to evaluate the mental status through a cross-sectional survey and gather related theoretical evidence for psychological intervention on postgraduate students majoring in stomatology.MethodsAn online survey was administered, and subjective well-being, anxiety, stress and depression symptoms were assessed using the 5-item World Health Organization Well-Being Index (WHO-5), item Generalized Anxiety Disorder Scale (GAD-7), 10-item Perceived Stress Scale (PSS-10), and Patient Health Questionnaire-9 (PHQ-9), respectively, wherein suicidal ideation and sleep-related problems were measured with PHQ-9 and Insomnia Severity Index (ISI).ResultsA total of 208 participants who completed one questionnaire were considered as valid. It was found that female respondents generally exhibited significantly higher levels of PSS-10, PHQ-9, and GAD-7 scores and shorter physical activity hours than male students. Students from rural areas demonstrated significantly higher levels of PHQ-9, suicidal ideation, and less portion of good or fair family economic support. Additionally, individuals from only-child families reported increased levels of activity hours (1.78 ± 2.07, p = 0.045) and a higher portion (55.10%, p = 0.007) of having clear future plan as compared with multiple-child families. The risk factors for anxiety symptoms (GAD-7 score) were higher scores of PSS-10 (OR = 1.15, 95% CI = 1.09–1.22), PHQ-9 (OR = 1.35, 95% CI = 1.22–1.49), and ISI-7 (OR = 1.14, 95% CI = 1.06–1.23), while owning a clear graduation plan was the protective factor (OR = 0.55, 95% CI = 0.31–0.98). Moreover, the risk factors for depressive symptoms (PHQ-9) included PSS-10 (OR = 1.10, 95% CI = 1.04–1.16), GAD-7 (OR = 1.38, 95% CI = 1.25–1.52), suicidal ideation (OR = 5.66, 95% CI = 3.37–9.51), and ISI-7 (OR = 1.17, 95% CI = 1.09–1.25). Approximately 98.08% of Chinese postgraduates studying stomatology reported experiencing at least moderate stress after the COVID-19 restrictions.ConclusionWithin the limitations of this study, senior students were more inclined to stress, while anxiety symptoms were related to severer levels of stress, depression, and insomnia. Depressive symptoms were associated with higher levels of stress, anxiety, insomnia, suicidal ideation, and lower levels of self-reported well-being. Thus, psychological interventions for postgraduates should be timely and appropriately implemented by strengthening well-being, reasonably planning for the future, and good physique, thereby mitigating the psychological issues after COVID-19 restrictions.

Different correlation between depressive symptoms and sleep duration on weekdays/weekends among adolescents in Taiyuan, North China

ObjectiveIn Chinese adolescents, the co-occurrence of depressive symptoms and short sleep duration constitute a serious public health issue. This study investigates the association between depressive symptoms and sleep duration of Chinese adolescents on weekdays as well as weekends. MethodsA multistage random cluster selection was utilized to select 2660 adolescents in Taiyuan, China. The survey contents included demographic characteristics, sleep duration, and depressive symptoms. ResultsAbout 41.95 % of students reported depressive symptoms with an average sleep duration of 7.71 ± 0.90 h. After adjusting for covariates, depressive symptoms were found to be positively correlated with sleep duration <6 h (OR = 1.88, 95 % CI: 1.20, 2.95) and 6 ~ h (OR = 1.61, 95 % CI: 1.18, 2.20) on weekdays, and sleep duration <6 h (OR = 2.10, 95 % CI: 1.17, 3.79) and 6 ~ hours (OR = 1.74, 95 % CI: 1.16, 2.62) on weekends compared with a sleep duration of 8 ~ hours. Only on weekdays, sleep duration of 7 ~ hours was positively correlated with depressive symptoms (OR = 1.39, 95%CI: 1.05, 1.84). On weekends, it was not associated with depressive symptoms (OR = 1.06, 95%CI: 0.82, 1.39). In subgroup analyses, female students (OR = 2.88, 1.97, 1.50) and middle school students (OR = 3.50, 2.07, 1.50) were more likely to experience depressive symptoms on weekdays with a sleep duration of <6 h, 6 ~ hours and 7 ~ hours. LimitationsSleep duration and depressive symptoms were self-reported measures. ConclusionThe study highlights that short sleep duration (< 7 h) increases the risk of depressive symptoms among adolescents regardless of weekdays or weekends. Just on weekdays, the sleep duration of 7 ~ hours was a risk factor for depressive symptoms. Further, gender, grade, and the only-child played significant modification effects between depressive symptoms and sleep duration. To conclude, this study will assist in the effective promotion of the education of adolescents' sleep health.

Adolescent Depression: Impact of Family Relations

Depression is a major mental disorder that affects numerous people and causes them to experience depressive episodes. The root of depression usually appears in people’s teenage years. Research have shown that family relations, in particular, has the largest impact on the development and manifestation of depressive symptoms in teenagers. After reviewing pertinent literature, the specific components in family relations that are risk factors and protective factors for depressive symptoms in adolescents are identified. The risk factors for depressive symptoms in teenagers are mostly correlated with negative family emotions and actions, which includes parental criticism and expressed emotions, parental depression, lack of family cohesion and adaptability, lack of parental care, negative family emotional climate, and lack of physical affection and verbal intimacy. The protective factors revolve around adolescents’ ability to recognize and manage negative emotions, which includes emotion regulation, positive family climate and social support, emotion coaching, emotion clarity, and cooperative communication. Four recommendations for parents are offered based on these observed risk factors and protective factors to hinder and prevent the development of depression adolescents. These recommendations are social support, positive family atmosphere, physical affection, and verbal affection. It is hoped that studies in the future can focus on investigating the effectiveness of these recommendations and provide a more detailed and reliable list of recommendations for parents to reduce the chances of depression development in their children.

An Intersectional Approach to Understanding the Psychological Health Effects of Combining Work and Parental Caregiving.

Role theory suggests occupying simultaneous family caregiving and employment roles in midlife may exert positive and negative effects on psychological health. However, there is a lack of causal evidence examining the degree to which combinations of these roles influence psychological health at the intersection of gender and racial identity. Longitudinal data from the Health and Retirement Study (2004-2018) are used to estimate a series of individual fixed effects models examining combinations of employment status and parental caregiving situation on CES-D depression scores among Black and White men and women aged 50-65. Subsequent models were stratified by intensity of caregiving situation and work schedule. Individual fixed effects models demonstrate combining work and parental caregiving is associated with greater depressive symptoms than only working, and with lower depressive symptoms than only caregiving, suggesting that paid employment exerts a protective effect on psychological health while parental caregiving may be a risk factor for depressive symptoms in later life. Analyses using an intersectional lens found that combining paid work with parental caregiving exerted a protective effect on CES-D scores among White women and men regardless of participants' intensity of care situation or work schedule. This effect was not present for Black men and women. Accounting for intersectionality is imperative to research on family caregiving, work, and psychological health.

Interaction effect of screen time and sugar-sweetened beverages with depressive symptoms in adolescents: evidence from a large sample-based survey in China.

Excessive screen time and the consumption of sugar-sweetened beverages are found to be independent predictors of depressive symptoms. However, the potential interaction effect of screen time and sugar-sweetened beverages, that is, whether one exposure factor strengthens the association of another with depressive symptoms, remains unclear. A large-scale adolescent health surveillance survey was conducted in 27 schools in eight regions across China. A total of 22,868 students were recruited to complete an eligible questionnaire to provide details of their screen time and sugar-sweetened beverage consumption. Depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9). Multiplicative and additive interaction models were performed to estimate the interaction effects of screen time and sugar-sweetened beverages on depressive symptoms, and whether the relationship varied by age group was also examined. The multivariate logistic regression model showed that even if the confounding factors were controlled, screen time and sugar-sweetened beverages were still risk factors for depressive symptoms in adolescents. Interaction models indicated that screen time and sugar-sweetened beverages in combination were related to greater odds of depressive symptoms. Compared with late adolescents, early adolescents had a higher probability of depressive symptoms when exposed to the joint effects. Our study may hopefully deepen the understanding of the association between screen time and sugar-sweetened beverages and depressive symptoms. Future research should further explore how and why screen time and sugar-sweetened beverages affect individuals more profoundly in early adolescence than in late adolescence and how to mitigate this.

Exploring the interplay of frailty, physical function, physical activity, nutritional status, and their association with quality of life and depressive symptoms in older adults with the frailty phenotype.

This study aimed to explore the interplay between frailty, physical function, physical activity, nutritional status, and their impact on the quality of life and depressive status in older adults with frailty. A cross-sectional study involving 235 pre-frail/frail older adults residing in Spanish communities was conducted. Frailty was assessed using Fried's criteria, physical function was evaluated using the Short Physical Performance Battery, and physical activity levels were measured via wrist-worn accelerometers. Nutritional status was determined using the Mini-Nutritional Assessment alongside anthropometric measurements. Quality of life was gauged using the EuroQoL 5-Dimension 5-Level, while depressive status was assessed using the Yesavage 15-item Geriatric Depression Scale. Multivariate linear regression and logistic regression analyses were employed to elucidate the associations of these factors with quality of life and depression. Our findings revealed significant correlations between various factors and quality of life. Notably, reported fatigue (β=-0.276, p=0.002), performance in the 4-m gait test (β=-0.242, p=0.001), the score on the short version of the Mini-Nutritional Assessment (β=0.312, p=0.002), and engagement in light physical activity (β=0.180, p=0.023) were all found to be associated with quality of life. In terms of depressive symptoms, the Mini-Nutritional Assessment score emerged as a protective factor (Odds ratio, OR: 0.812, p<0.001), as did participation in moderate physical activity (OR: 0.988, p=0.028). Conversely, fatigue (OR: 3.277, p=0.003) and a slow gait speed (OR: 1.136, p=0.045) were identified as risk factors for depressive symptoms. This study underscores the detrimental association of fatigue and slow gait speed on both quality of life and depressive status among older adults with frailty. In contrast, engaging in physical activity and addressing malnutrition risk emerge as critical protective factors for enhancing quality of life and ameliorating depressive symptoms in this population. This is a study that uses cross-sectional data from a trial registered at ClinicalTrials.gov (Identifier: NCT05610605).

Fear and depression among health care professionals: a cross-sectional study during COVID-19 pandemic in Bangladesh

Background: COVID-19 pandemic is a public health emergency of international concern that can result in severe mental health conditions like depression and fear in health-care professionals (HCPs). Methods: A cross-sectional study was conducted, where 834 HCPs were self-recruited via social media. Multiple linear regression analyses were performed to identify predicting factors. Results: Approximately one-third of the total participants were depressed (27.3%) and those with depressive symptoms had significant fear of COVID-19. Significant risk factors for depressive symptoms were being female, being married, having no children, having high risk elderly persons at home, being afraid of death due to COVID-19 and having comorbid diseases. Fear of death due to COVID-19 was the most common significant contributing factor the scales for depression model, β=0.397, for fear of COVID-19 model and β=0.478 respectively. Quality of PPE played a vital role for depression as majority of HCPs. About 65.3% of HCPs who were restless while examining a patient with flu symptoms and majority of HCPs who felt insecure about their family members. Conclusions: Most of the HCPs faced several challenges during COVID-19 and psychological impacts of frontline HCPs were associated with interventions and rehabilitations to improve the mental health.

Associations of problematic smartphone use with depressive symptoms and suicidal ideation in university students before and after the COVID-19 outbreak: A meta-analysis

Background and aimProblematic smartphone use (PSU) has been suggested to present with depressive symptoms and suicidal ideation (SI) as well as sleep disturbance, lack of social support, and emotional isolation. The aim of this systematic review and meta-analysis was to evaluate the association between PSU with depressive symptoms and SI in university students, and to determine the potential influence of the coronavirus disease 2019 (COVID-19) outbreak. MethodsObservational studies pertinent to our research were identified through comprehensive searches of the PubMed, Embase, Cochrane Library, and Web of Science databases. To account for potential heterogeneity, the random-effects models were employed to aggregate the findings. ResultsEighteen datasets from 17 case-control studies, including 24,019 university students, were included. Among them, 8,775 (36.5 %) had PSU. A higher prevalence of depressive symptoms (odds ratio [OR]: 2.40, 95 % confidence interval [CI]: 2.19 to 2.63, p < 0.001; prediction interval: 1.95 to 2.96) was observed in university students with higher scores for PSU measures. A subgroup analysis showed a stronger association between PSU and depressive symptoms after the COVID-19 outbreak as compared to that before the outbreak (OR: 2.76 versus 2.16, p for subgroup difference = 0.002), which explained the heterogeneity. The association between PSU and depressive symptoms in university students was similar to those reported in studies from China and other countries, and in studies with different quality scores. Finally, a meta-analysis of three studies suggested that PSU was also associated with the prevalence of SI (OR: 2.18, 95 % CI: 1.77 to 2.68, p < 0.001; I2 = 0 %). ConclusionIn university students, PSU may be a risk factor for depressive symptoms and SI, and the association between PSU and depressive symptoms became stronger after the COVID-19 outbreak.

The association between sarcopenia and incident of depressive symptoms: a prospective cohort study

BackgroundEpidemiological studies have shown that sarcopenia was associated with depression among older adults. However, most of these investigations used a cross-sectional design, limiting the ability to establish a causal relation, the present study examined whether sarcopenia was associated with incident depressive symptoms.MethodsThis is a prospective cohort study with participants from the Western China Health and Aging Trends (WCHAT) study. Participants could complete anthropometric measurements and questionnaires were included. The exposure was sarcopenia, defined according to the Asian Working Group for Sarcopenia in 2019, the outcome was depressive symptoms, evaluated by GDS-15. We excluded depression and depressive symptoms at baseline and calculated the risk of incident depressive symptoms during the follow-up year.ResultsA total of 2612 participants (mean age of 62.14 ± 8.08 years) were included, of which 493 with sarcopenia. 78 (15.82%) participants with sarcopenia had onset depressive symptoms within the next year. After multivariable adjustment, sarcopenia increased the risk of depressive symptoms (RR = 1.651, 95%CI = 1.087–2.507, P = 0.0187) in overall participants. Such relationship still exists in gender and sarcopenia severity subgroups. Low muscle mass increased the risk of depressive symptoms (RR = 1.600, 95%CI = 1.150–2.228, P = 0.0053), but low muscle strength had no effect (RR = 1.250, 95%CI = 0.946–1.653, P = 0.117).ConclusionsSarcopenia is an independent risk factor for depressive symptoms, Precautions to early detect and targeted intervene for sarcopenia should continue to be employed in adult with sarcopenia to achieve early prevention for depression and reduce the incidence of adverse clinical outcomes.

Regional differences in the effects of healthy aging on depressive symptoms: a Korean longitudinal study of aging (2006-2020).

Depression is a widely prevalent, often recurrent condition. To analyze the regional differences in depressive symptoms over time, we investigated urban-rural differences in change in depression over time in South Korea and the association between healthy aging and depressive symptoms among middle-aged and older adults. Data collected in the Korean Longitudinal Study of Aging, from 2006 to 2020, of adult participants aged ≥45 years without depressive symptoms were analyzed. Healthy aging was defined under five principal components: absence of chronic disease, good physical function, normal cognitive function, active social engagement, and good psychological adaptation. Depressive symptoms were measured using the short version of the Center for Epidemiologic Studies Depression Scale. Using the Andersen-Gill model for recurrent time-to-event, we examined the effect of healthy aging on depressive symptoms, with a subgroup analysis based on the residential area. Of the 7,708 participants, 78.2% lived in urban areas and 39.4% achieved healthy aging. In 2008, rural residents had a higher incidence of depressive symptoms (rural 11.8%; urban 8.9%); however, after 2016, the depressive symptoms of urban residents gradually increased (rural 6.4%; urban 12.1%). Unhealthy aging (adjusted hazard ratio = 3.04, 95% confidence interval: 2.72-3.39) and urban residence (adjusted hazard ratio = 1.15, 95% confidence interval: 1.06-1.24) were risk factors for depressive symptoms. The subgroup analysis revealed that individuals who did not achieve healthy aging had an increased risk of depressive symptoms, regardless of their residential area (hazard ratio [95% confidence interval]: urban, 3.13 [2.75-3.55]; rural 2.59 [2.05-3.28]). As urbanization accelerates, urban residents have a higher risk of depressive symptoms than rural residents. Healthy aging is an essential factor in reducing depressive symptoms. To achieve healthy aging, appropriate interventions and policies that target the middle-aged adults and gradually extend to older adults are needed, considering individual and regional factors.

Association between dietary diversity, sedentary time outside of work and depressive symptoms among knowledge workers: a multi-center cross-sectional study

BackgroundLow-diversity diets and sedentary status are risk factors for depressive symptoms, while knowledge workers were ignored before. The purpose of this current study was to examine the relationship between dietary diversity, sedentary time spent outside of work, and depressive symptoms among knowledge workers.Study design and methodsThis was a multicenter and cross‐sectional design that included 118,723 knowledge workers. Participants self-reported online between January 2018 and December 2020. Demographic information, the Dietary Diversity Scale, the Patient Health Questionnaire-9, dietary habits (which included eating three meals on time, midnight snacking, overeating, social engagement, coffee consumption, sugary drink consumption, smoking and alcohol use), sedentary time spent outside of work and physical activity were investigated.ResultsThe relationships between demographic information, dietary habits and dietary diversity, and depressive symptoms were estimated. Compared with the first and second levels of dietary diversity, the third level of dietary diversity (OR: 0.91; 95% CI: 0.84–0.98) reduced the risk of depressive symptoms. Knowledge workers with different degrees of sedentary status (2–4 h (OR: 1.11; 95% CI: 1.07–1.14), 4–6 h (OR: 1.21; 95% CI: 1.17–1.26), and > 6 h (OR: 1.49; 95% CI: 1.43–1.56), presented a progressively higher risk of depressive symptoms.ConclusionHigh amounts of sedentary time spent after work and low levels of dietary diversity are risk factors for depressive symptoms. In addition, an irregular diet and overeating are also major risk factors for knowledge workers.

SLEEP DISTURBANCE AND DEPRESSIVE SYMPTOMS AMONG OLDER ADULTS: DO GENDER DIFFERENCES EXIST?

Abstract Sleep is a key part of a healthy lifestyle, but aging causes sleep problems by decreased melatonin levels. Sleep disturbance includes problems falling or staying asleep, too much sleep, or obstructive sleep apnea (OSA), the most common sleep-related breathing disorder in older adults. Thus, aging-related changes in sleep should be studied in various aspects of elderly’s health such as physical, mental, and cognitive health. As part of that, this study aims to (1) examine the connection between sleep disturbance and depressive symptoms and (2) investigate whether gender differences exist. Participants were Korean adults aged 65 and older (N=1,316) from the 2020 Korean National Health and Nutrition Examination Survey. The survey measured sleep disturbances (OSA, insomnia, hypersomnia), depressive symptoms, and sociodemographic characteristics. Hierarchical multiple regression analysis was conducted to examine whether sleep disturbances influence depressive symptoms and test the interaction between sleep disturbance and gender. Results revealed that after adjusting for covariates, those with more risk factors for OSA (B=1.056, p=.000) or with insomnia (B=1.527, p=.000) were more likely to have greater depressive symptoms than their counterparts. Additionally, the relative influences of OSA (B=1.295, p=.000) or insomnia (B=.965, p=.023) on depressive symptoms were contingent upon gender. However, no correlation was observed between hypersomnia and depressive symptoms. Although both OSA and insomnia are risk factors for depressive symptoms, older women with OSA or insomnia showed more severe depressive symptoms than older men with OSA or insomnia. Findings suggest the need to make sophisticated approaches considering homogeneity and heterogeneity within older adults.

Effects of parenting style on depressive symptoms, anxiety symptoms, and their comorbidity during the COVID-19 pandemic lockdown among 3117 Chinese junior high school students

IntroductionDepressive symptoms, anxiety symptoms, and comorbidity increased in junior high school students due to the outbreak of COVID-19. The objective of this study was to measure the impacts of parenting style on depressive symptoms, anxiety symptoms, and their comorbidity in Chinese junior high school students during the COVID-19 pandemic lockdown period. MethodsAn online survey was conducted in June 2020 among 3117 junior high school students from Shandong Province, China. The Egna Minnen av Barndoms Uppfostran scale was used to measure parenting styles. The 9-item Patient Health Questionnaire scale and the 7-item Generalized Anxiety Disorder scale were used to measure depressive symptoms and anxiety symptoms, respectively. Multinomial logistic regression was conducted with SPSS 25.0 Version. Results3117 junior school students enrolled in this study. The prevalence of depressive symptoms only, anxiety symptoms only, and comorbidity among junior high school students was 11.55 %, 5.29 %, and 22.97 %. Paternal over-protection was a risk factor not only for depressive symptoms only (OR = 1.075, 95 % CI = 1.020–1.134) but for anxiety symptoms only (OR = 1.090, 95 % CI = 1.016–1.170) and comorbidity (OR = 1.098, 95 % CI = 1.050–1.148). Paternal over-interference was a protective factor for depressive symptoms only (OR = 0.947, 95 % CI = 0.908–0.987) and comorbidity (OR = 0.953, 95 % CI = 0.921–0.986). However, maternal over-interference and over-protection were risk factors for depressive symptoms only (OR = 1.039, 95 % CI = 1.011–1.068). LimitationsThis was a cross-sectional study and the causal inferences could not be conducted. ConclusionsJunior high school students with poorer family environmental factors were more likely to suffer from the comorbidity of anxiety symptoms and depressive symptoms during the COVID-19 pandemic lockdown. Decision-makers from the government, educational, and healthcare institutions should pay more attention to junior high school students at higher risk of mental disorders due to poor parenting styles. We should discuss family interventions in the future to prevent mental disorders in junior high school students.

Income inequality and depressive symptoms among Chinese adults: a quasi-experimental study

ObjectiveThere is a lack of causal evidence on the impact of income inequality on depressive symptoms. The impact of China's Targeted Poverty Alleviation (TPA) policy on depressive symptoms is also unclear. Using a quasi-experimental design, this study aims to investigate the causal effects of TPA and income inequality on depressive symptoms among Chinese adults. Study designThis is a population-based study. MethodsThree waves (2012, 2016, and 2018) of the China Family Panel Studies (CFPS), a nationally representative sample of China, were included in this study. We performed difference-in-difference (DID) models to assess the effect of TPA and income inequality on depressive symptoms. We further conducted the mixed effect models to examine the impact of income inequality on depressive symptoms. The study considered a range of spatial factors and spatial splines to address spatial autocorrelations. ResultsThis study included valid measures of depressive symptoms (Center for Epidemiologic Studies Depression Scale [CES-D-8] score) from 14,442 adults of CFPS. The DID results indicated that at the provincial level, the CES-D-8 score of the TPA treatment group was on average 0.570 (95% confidence interval [CI]: 0.358–0.783) less than the control group. Furthermore, a 0.1 increase in Gini index would lead to a 0.256 (95% CI: 0.064–0.448) increase in CES-D-8 score. The mixed effect model showed that income inequality was a risk factor for depressive symptoms at the provincial level (excess risk = 5.602% [95% CI: 3.047%–8.219%]). ConclusionsOur findings suggest that income inequality adversely affects mental health, but China's Targeted Poverty Alleviation improves the mental health of the Chinese population.

Associations between individual cognitive factors, mode of exposure and depression symptoms in practitioners working with aversive crime material

ABSTRACT Background: There is extensive literature on front-line officers and investigators exposure to trauma and its negative impact on them. However, there are analytical practitioners in law enforcement who indirectly work with the traumatic experiences of other people daily, but are seldom the focus of academic research. Objective: Our goal was to conduct the first international study with these practitioners to identify the risk of depression symptoms and establish whether potentially modifiable risk factors (belief in a just world, mental imagery and thought suppression) and work-related characteristics (medium of exposure) are associated with depression. Method: 99 analysts and secondary investigators employed in police and law enforcement organizations from the UK, Europe and Canada participated in the study. The online survey was advertised to employees via their employers but hosted without employer access. Multiple regression was used to analyze the data. Results: After controlling for age, gender, ethnicity, previous exposure to trauma, and marital status, four potential risk factors were identified. Analytical practitioners with vivid mental imagery, those exposed to crime material via auditory and visual means, those who suppressed intrusive thoughts, and those who believed in a just world reported more depressive symptoms. Conclusions: The majority of our sample reported clinical levels of depressive symptoms. Four potential risk factors accounted for just under half of the variance in depression scores. We consider strategies that can be used to mitigate the potential negative influence of these factors and suggest that these are established as risk factors for depression symptoms via future longitudinal research.

Absolute and relative preferences for mobile phone internet content, mobile phone dependence, and depressive symptoms: a study of Chinese university students in the post-pandemic era.

Due to the COVID-19 pandemic, Chinese university students may have increased mobile phone dependence, a habitual behavior in the student population and a risk factor for depressive symptoms. Therefore, this study explored the association between mobile phone dependence and depressive symptoms in Chinese university students in the post-pandemic era. It also investigated the effects of different types and categories of mobile phone Internet content preferences. In particular, this study examined whether mobile phone dependence mediates the relationship between absolute preference (AP) for mobile phone Internet content and depressive symptoms, and whether relative preference (RP) for mobile phone Internet content moderates the association between mobile phone dependence and depressive symptoms. A cross-sectional study of Chinese university students recruited through Credamo was conducted in February-March, 2023. Participants completed the Mobile Phone Internet Content Preference Questionnaire, Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use, and Center for Epidemiological Survey, Depression Scale. Statistical analyses included descriptive statistics, correlation, regression, and analyses of mediation and moderation effects. The final sample comprised 1,602 students (709 males). We found a positive association between mobile phone dependence and depressive symptoms. The mediating role of mobile phone dependence between AP for mobile phone Internet content and depressive symptoms differed according to the type and category of content. Meanwhile, different types and categories of RP for mobile phone Internet content moderated the association between mobile phone dependence and depressive symptoms in opposite directions. Our results highlight the interrelationships among mobile phone Internet content preferences, mobile phone dependence, and depressive symptoms in Chinese university students. For different types and categories of mobile phone Internet content preferences, we propose distinct preventive measures to alleviate students' depressive symptoms.

Prevalence and determinants of depressive symptoms among community-dwelling older adults in China based on differences in living arrangements: a cross-sectional study

BackgroundOlder adults with different living arrangements may have different mental health statuses and different factors that influence their mental health. The aim of the present study is to investigate the prevalence and determinants of depressive symptoms among community-dwelling older adults in China based on differences in their living arrangements.MethodsParticipants were 6,055 older adults from the 2015 China Health and Retirement Longitudinal Study. Depressive symptoms and their determinants were evaluated using the 10-item Center for Epidemiologic Studies Depression Scale and multivariate logistic regression analysis, respectively.ResultsThe prevalence of depressive symptoms among older adults living alone, as a couple, and with children was 47.8%, 33.2%, and 39.5%, respectively. The common risk factors for depressive symptoms were shorter sleep duration, poorer activities of daily living, and poorer self-rated health. Women, those with lower educational levels, and those suffering from chronic diseases had a higher risk of depressive symptoms among older adults living as a couple and those living with children. Smoking and participation in economic activities were also risk factors of depressive symptoms among older adults living with children and those living alone, respectively.ConclusionsThe findings suggest that older adults living as couples had the lowest prevalence of depressive symptoms, while those living alone had the highest prevalence of depressive symptoms. The determinants of depressive symptoms differed by living arrangement; hence, they should be considered in future interventions.

The moderating effect of self-efficacy between social constraints, social isolation, family environment, and depressive symptoms among breast cancer patients in China: a cross-sectional study.

For female breast cancer patients, the psychological status after surgery, especially the social and family psychological-related factors, deserves more attention. This study analyzed the influence of social constraints, social support, social isolation, family conflict, and family emotion expression on depression. At the same time, this study conducted the relationship between the variables and the mechanism of action. We conducted a cross-sectional study and 522 breast cancer patients finished questionnaires consisting of Self-Rating Depression Scale (SDS), General Self-Efficacy Scale (GSES), Multi-Dimensional Scale of Perceived Social Support (MSPSS), Social Constraints Scale-5 (SCS-5), Family Environment Scale (FES), and Lubben Social Network Scale (LSNS-6). Multivariable logical regression was used to explore influencing factors. Pearson's correlation, hierarchical regression, and simple slope analysis were conducted to verify the role of self-efficacy. 71.6% of patients had depressive symptoms. Family contradiction (OR = 10.086), social constraints (OR = 2.522), social isolation (OR = 2.507), and high blood glucose (OR = 2.156) were risk factors of depressive symptoms. Family emotional expression (OR = 0.480), family intimacy (OR = 0.235), and self-efficacy (OR = 0.246) were protective factors against depressive symptoms. The interactive items interpretation quantity were as follows: Contradiction*Self-efficacy (ΔR2 = 2.3%, P < 0.001), Emotional expression*Self-efficacy (ΔR2 = 2.6%, P < 0.001), Intimacy*Self-efficacy (ΔR2 = 1.0%, P = 0.018), Social constraints*Self-efficacy (ΔR2 = 1.0%, P = 0.008), Social networks*Self-efficacy (ΔR2 = 1.0%, P = 0.010), Blood Glucose*Self-efficacy (ΔR2 = 0.6%, P = 0.023). The influence of independent variables on depressive symptoms was gradually decreased in the low, mean, and high groups of self-efficacy. Postoperative Chinese breast cancer survivors reported higher depressive symptoms. Social, family, and physiological factors could affect depressive symptoms, in which self-factor played moderator roles.

Urban-rural disparities of depression symptoms and its influencing factors among the elderly aged ≥65 years old in Anhui Province from 2019 to 2020

Objective: To analyze the difference in depression symptoms and influencing factors between urban and rural elderly people aged ≥65 years old in Anhui Province. Methods: Based on the data from a survey of 68 communities in Anhui Province that implemented the National Elderly Psychological Care Project from 2019 to 2020, the current status of depression symptoms in the elderly was evaluated using the Patient Health Questionnaire-9 (PHQ-9). The difference in the detection rate of depression symptoms between urban and rural elderly people with different characteristics was compared by using the χ2 test. The logistic regression model was used to analyze the relevant factors of depression symptoms in urban and rural elderly people. Results: A total of 15 532 elderly people aged≥65 years old were included in the survey. The detection rate of depressive symptoms was 7.12%, which was higher in rural areas (9.08%) than in urban areas (6.48%). Logistic regression showed that chronic diseases were risk factors for depressive symptoms in elderly people from both urban and rural areas. Positive attitudes towards aging and good mental resilience were protective factors for depressive symptoms in elderly people. Having hobby (OR=0.64, 95%CI: 0.45-0.91), good relationship with children (OR=0.56, 95%CI: 0.41-0.76), good relationship with spouse (OR=0.51, 95%CI: 0.37-0.71), and having at least 6 friends (OR=0.48, 95%CI: 0.32-0.71) were the protective factors for depressive symptoms in urban elderly people. A good relationship with neighbors (OR=0.58, 95%CI: 0.41-0.82) and having 1-2 friends (OR=0.40, 95%CI: 0.25-0.64) were the protective factors for depressive symptoms in rural elderly people. Women (OR=1.49, 95%CI: 1.06-2.10) and higher education level (OR=1.81, 95%CI: 1.19-2.74, compared with illiterate/semi-illiterate in primary school; OR=2.94, 95%CI: 1.82-4.76, compared with illiterate/semi-illiterate in junior high school and above) were the risk factors for depressive symptoms in rural elderly people. Conclusion: There are differences between urban and rural areas in depressive symptoms among elderly people in Anhui Province. The detection rate of depression symptoms among rural elderly people is higher, and the influencing factors of depressive symptoms between urban and rural elderly people are also different, which should be treated specifically in the implementation of intervention measures.
