RESUMO
OBJECTIVES: There is little research conducted to systematically synthesize the evidence on psychological interventions for social isolation and loneliness among older adults during medical pandemics. This systematic review aims to address this information gap and provides guidance for planning and implementing interventions to prevent and reduce loneliness and social isolation for older adults, especially during medical pandemics. METHODS: Four electronic databases (EMBASE, PsychoInfo, Medline and Web of Science) and grey literature from 1 January 2000 to 13 September 2022 were searched for eligible studies on loneliness and social isolation. Data extraction and methodological quality assessment on key study characteristics were conducted independently by two researchers. Both qualitative synthesis and meta-analysis were used. RESULTS: The initial search yielded 3,116 titles. Of the 215 full texts reviewed, 12 intervention articles targeting loneliness during the COVID-19 pandemic met the inclusion criteria. No studies were found concerning intervention with respect to social isolation. Overall, interventions targeting social skills and the elimination of negativities effectively alleviated the feelings of loneliness in the older population. However, they had only short-term effects. CONCLUSION: This review systematically summarised the key characteristics and the effectiveness of existing interventions addressing loneliness in older adults during the COVID-19 pandemic. Future interventions should focus on social skills and eliminating negativities and be tailored to the needs and characteristics of older people. Repeated larger-scale randomized controlled trials and long-term effectiveness evaluations on this topic are warranted.

OBJECTIVES: Pandemics and their public health control measures have generally substantially increased the level of loneliness and social isolation in the general population. Because of the circumstances of aging, older adults are more likely to experience social isolation and loneliness during pandemics. However, no systematic review has been conducted or published on the prevalence of loneliness and/or social isolation among the older population. This systematic review and meta-analysis aims to provide up-to-date pooled estimates of the prevalence of social isolation and loneliness among older adults during the COVID-19 pandemic and other pandemics in the last two decades. DESIGN: EMBASE, PsychoINFO, Medline, and Web of Science were searched for relevant studies from January 1, 2000 to November 31, 2021 published in a variety of languages. Only studies conducted during the COVID-19 pandemic were selected in the review. RESULTS: A total of 30 studies including 28,050 participants met the inclusion criteria. Overall, the pooled period prevalence of loneliness among older adults was 28.6% (95% CI: 22.9-35.0%) and 31.2% for social isolation (95% CI: 20.2-44.9%). Prevalence estimates were significantly higher for those studies conducted post 3-month from the start of the COVID-19 pandemic compared to those conducted within the first 3 months of the pandemic. CONCLUSIONS: This review identifies the need for good quality longitudinal studies to examine the long-term impact of pandemics on loneliness and social isolation among older populations. Health policymaking and healthcare systems should proactively address the rising demand for appropriate psychological services among older adults.

BACKGROUND: The sociodemographic characteristics and clinical features of the Late-life depression (LLD) patients in psychiatric hospitals have not been thoroughly studied in China. This study aimed to explore the psychiatric outpatient attendance of LLD patients at a psychiatric hospital in China, with a subgroup analysis, such as with or without anxiety, gender differences. METHODS: This retrospective study examined outpatients with LLD from January 2013 to August 2019 using data in the Observational Medical Outcomes Partnership Common Data Model (OMOP-CDM) in Beijing Anding Hospital. Age, sex, number of visits, use of drugs and comorbid conditions were extracted from medical records. RESULTS: In a sample of 47,334 unipolar depression patients, 31,854 (67.30%) were women, and 15,480 (32.70%) were men. The main comorbidities of LDD are generalized anxiety disorder (GAD) (83.62%) and insomnia (74.52%).Among patients with unipolar depression, of which benzodiazepines accounted for the largest proportion (77.77%), Selective serotonin reuptake inhibitors (SSRIs) accounted for 59.00%, a noradrenergic and specific serotonergic antidepressant (NaSSAs) accounted for 36.20%. The average cost of each visit was approximately 646.27 yuan, and the cost of each visit was primarily attributed to Western medicine (22.97%) and Chinese herbal medicine (19.38%). For the cost of outpatient visits, depression comorbid anxiety group had a higher average cost than the non-anxiety group (p < 0.05). There are gender differences in outpatient costs, men spend more than women, for western medicine, men spend more than women, for Chinese herbal medicine, women spend more than men (all p < 0.05). The utilization rate of SSRIs and benzodiazepines in female patients is significantly higher than that in male patients (p < 0.05). CONCLUSION: LLD patients are more commonly women than men and more commonly used SSRIs and NaSSAs. Elderly patients with depression often have comorbid generalized anxiety. LLD patients spend most of their visits on medicines, and while the examination costs are lower.

BACKGROUND: This study aimed to compare prevalence and risk factors of somatization (SOM) between health care workers and non-health care workers during COVID-19 outbreak in China. METHODS: From 14 February to 29 March 2020, an online survey was performed in both 605 health care workers and 1151 non-health care workers. Based on the somatization dimension score of the Symptom Checklist-90, participants were divided into non-SOM group and SOM group. RESULTS: Health care workers had higher prevalence rate of SOM (p < 0.001) than non-health care workers, with an OR of 1.70 (95% CI, 1.22-2.36, p = 0.002). Multiple logistic regression analysis revealed that in non-health care workers, the risk factors of SOM included other ethnicities, insomnia, and suicide, while in health care workers, the risk factors included working 6-8 h per day, and working ≥10 h per day during COVID-19 outbreak. CONCLUSIONS: Our research suggests that both non-health care workers and health care workers have a relatively high prevalence of somatization. However, the related factors for somatization in both groups are significantly different, showing that medical service-related factors are associated with somatization in health care workers, while demographic and clinical factors are associated with somatization in non-health care workers.

PURPOSE: Past suicide attempts (SA) are a major contributor to suicide. The prevalence of SA in pregnant and postpartum women varied significantly across studies. Therefore, this meta-analysis was conducted to examine the prevalence of SA and its mediating factors in this population. METHODS: Relevant articles published in PubMed, EMBASE, Web of Science, PsycINFO, Medline complete, Chinese National Knowledge Infrastructure database (CNKI), Chinese Wanfang and Chongqing VIP database were systematically searched from inception to March 28, 2019. Titles, abstracts and full texts were reviewed independently by three researchers. Studies were included if they reported data on SA prevalence or provided relevant data that enabled the calculation of SA prevalence. Data were extracted by two researchers and checked by one senior researcher. The random-effects model was used to analyze data by the CMA 2.0 and Stata 12.0, with the high degree of statistical heterogeneity present. The primary outcomes were prevalence of SA with 95% CI during pregnancy and during the first-year postpartum. RESULTS: Fourteen studies covering 6,406,245 pregnant and postpartum women were included. The pooled prevalence of SA was 680 per 100,000 (95% confidence interval 0.10-4.69%) during pregnancy and 210 per 100,000 (95% confidence interval 0.01-3.21%) during the first-year postpartum. Data source was significantly associated with prevalence of SA in the subgroup analysis (pregnancy, p < 0.001; the first-year postpartum, p = 0.013). CONCLUSION: The prevalence of SA is not high in pregnant and postpartum women. Due to the potential loss of life and negative impact of SA on health outcomes, however, careful screening and effective preventive measures should be implemented for this population.

BACKGROUND: The apolipoprotein E (ApoE) gene polymorphisms are correlated with blood lipid levels and several neuropsychiatric symptoms. Therefore, this study aimed to examine whether the ApoE rs429358 affected the development and clinical symptoms of schizophrenia and to explore the relationship between apolipoproteins levels and clinical symptoms. METHODS: The ApoE rs429358 was genotyped using a case-control design. The Positive and Negative Syndrome Scale (PANSS) was employed to evaluate the psychopathology of all patients. RESULTS: A total of 637 patients with schizophrenia and 467 healthy controls were recruited. We found no significant differences in the genotype and allele distribution between the patient and control groups. A significant correlation between PANSS negative symptoms and ApoA1 levels (p = 0.048) or ApoB levels (p = 0.001) was found in patients with schizophrenia, which was also confirmed by linear regression analyses (p = 0.048 vs. p = 0.001). Interestingly, only in the T homozygote group, ApoA1 and ApoB levels were predictors of the PANSS negative symptom score (p = 0.008 vs. p = 0.012), while in the C allele carrier group, no correlation was observed. CONCLUSIONS: This study found that the levels of ApoA1 and ApoB were negatively associated with negative symptoms of patients with schizophrenia. Furthermore, the association between ApoA1 or ApoB levels and psychopathology of schizophrenia was regulated by ApoE rs429358.
RESUMO
BACKGROUND: Clozapine treatment increases the risk of agranulocytosis, but findings on the epidemiology of agranulocytosis have been inconsistent. This meta-analysis examined the prevalence of agranulocytosis and related death in clozapine-treated patients. METHODS: A literature search in the international (PubMed, PsycINFO, and EMBASE) and Chinese (WanFang, Chinese National Knowledge Infrastructure, and Sinomed) databases was conducted. Prevalence estimates of agranulocytosis and related death in clozapine-treated patients were synthesized with the Comprehensive Meta-Analysis program using the random-effects model. RESULTS: Thirty-six studies with 260 948 clozapine-treated patients published between 1984 and 2018 were included in the meta-analysis. The overall prevalence of agranulocytosis and death caused by agranulocytosis were 0.4% (95% CI 0.3-0.6%) and 0.05% (95% CI 0.03-0.09%), respectively. The prevalence of agranulocytosis was moderated by sample size, study quality, year of publication, and that of data collection. CONCLUSIONS: The prevalence of clozapine-associated agranulocytosis is low. Agranulocytosis-related death appears rare.

PURPOSE: Poor sleep quality is common in medical students and is associated with a number of negative health outcomes. However, the prevalence estimates of poor sleep quality in medical students vary widely across studies. We thus conducted a meta-analysis of the prevalence of poor sleep quality and its mediating factors in medical students. METHODS: A systematic literature search of PubMed, EMBASE, Web of Science, PsycINFO, and Medline Complete was performed. The random-effects model was used to analyze the pooled prevalence of poor sleep quality and its 95% confidence intervals (CIs). RESULTS: A total of 57 studies with 25,735 medical students were included. The pooled prevalence of poor sleep quality was 52.7% (95% CI: 45.3% to 60.1%) using the Pittsburgh Sleep Quality Index (PSQI). The pooled mean total PSQI score across 41 studies with available data was 6.1 (95% CI: 5.6 to 6.5). Subgroup analyses found that PSQI cutoff value and study region were associated with the prevalence of poor sleep quality (P = 0.0003 VS. P = 0.005). Across the continents, poor sleep quality was most common in Europe, followed by the Americas, Africa, Asia, and Oceania. Meta-regression analyses found that smaller sample size (slope = - 0.0001, P = 0.009) was significantly associated with higher prevalence of poor sleep quality. CONCLUSIONS: Poor sleep quality is common among medical students, especially in Europe and the Americas continets. Due to the negative health outcomes, regular screening of poor sleep quality and effective interventions are needed for medical students.

PURPOSE: Obesity has been associated with an increased risk of the depression in the general population, but it is unknown whether this relationship applies equally to immigrants as well as non-immigrants. Furthermore, the nature of the relationship is uncertain, is it direct or curvilinear? The aim of this study is to examine the relationship between body mass index and major depressive episode among immigrants and non-immigrants. METHODS: To provide more statistically robust data, a series of cross-sectional health surveys of the Canadian population for the 5 years 2010-2014 were pooled to increase the number of immigrants in the study. Restricted cubic splines analysis was used to examine the nature of the association. RESULTS: Immigrants had lower 12-month depression and obesity prevalence rates than non-immigrants. In addition, it was found that non-immigrants were more likely to develop depression than immigrants, OR = 1.40 (95% CI, 1.16-1.67). Obese respondents were more likely to develop depression than normal weight respondents in both immigrant (OR = 1.55; 95% CI, 1.03-2.32) and non-immigrant groups (OR = 1.23; 95% CI, 1.15-1.32). A significant nonlinear elongated J-shaped association between obesity and depression was found for both immigrants and non-immigrants with increased risk of depression in obese individuals. CONCLUSION: Culture-specific, clinical-based interventions should be developed to improve the early identification, treatment and recovery of individuals with a high BMI particularly among those with BMIs in the obese range.

This is a meta-analysis of randomized controlled trials (RCTs) comparing cognitive behaviour therapy for insomnia (CBT-I) monotherapy with active control treatment for insomnia in patients with medical or psychiatric comorbidities. Both international (PubMed, EMBASE, PsycINFO, Cochrane Library) and Chinese (WanFang, and CNKI) databases were systematically searched. The random effects model was used. Thirteen RCTs comparing CBT-I (n = 441) and active controls (n = 412) groups were included. CBT-I group showed significant advantage over active controls at post-treatment assessment in terms of Insomnia Severity Index (ISI; SMD = -0.74), sleep onset latency (SMD = -0.36), wake after sleep onset (SMD = -0.21), sleep quality (SMD = 0.56), Pittsburgh sleep quality index total scores (PSQI; SMD = -0.76) and the total score of dysfunctional beliefs and attitudes about sleep scale (DBAS; SMD = -1.09). Subgroup analyses revealed significant improvement in sleep onset latency in patients with psychiatric disorders (SMD = -0.45), while significant reduction of number of wakeup after sleep onset was found in patients with medical conditions (SMD = -0.31). This meta-analysis found that CBT-I monotherapy had greater efficacy than other active control treatment for insomnia in patients with medical or psychiatric comorbidities.

Objective: This is a meta-analysis of the pooled prevalence of insomnia-specific sleep disturbances (sleep disturbances thereafter) and sleep quality in older Chinese adults. Method: Both English (PubMed, Embase and PsycINFO) and Chinese (Chinese National Knowledge Infrastructure [CNKI], WanFang and SinoMed) databases were systematically searched. Data extraction and quality assessment were independently performed by two investigators. Random-effects model was performed to pool the prevalence of sleep disturbances and sleep quality. Subgroup and meta-regression analyses were performed to explore the source of heterogeneity. Funnel plots, Egger's regression model, and Begg's test were used to assess publication bias. Results: A total of 47 studies were included. The pooled prevalence of sleep disturbances was 35.9% (95% CI: 30.6%-41.2%). Older adults in rural areas had higher prevalence of sleep disturbances than their counterparts in urban areas. Sleep quality was measured by the Pittsburgh Sleep Quality Assessment (PSQI) in all studies with available data. In the 27 studies with available data, the pooled mean PSQI total score was 6.64 (95% CI: 6.14-7.13). There was no significant difference between genders and between rural and urban areas. Compared to men, women had higher mean scores in sleep latency (Q = 23.62, p < 0.001), sleep efficiency (Q = 12.08, p = 0.001), and use of sleep-promoting medications (Q = 4.07, p = 0.044). Conclusion: Sleep disturbances are common in older Chinese adults, particularly in older women.

Major depressive disorder (MDD) is a common psychiatric disorder in China, but its reported treatment rate varies largely across different studies. The objective of this meta-analysis was to determine the pooled treatment rate for people with MDD in China and its associated factors. Both English (PubMed, Cochrane Library, PsycINFO, Web of Science) and Chinese (Chinese National Knowledge Infrastructure, WanFang and SinoMed) databases were searched from their commencement date to November 13, 2018. Epidemiological studies that reported the treatment rate of MDD were included and synthesized using a random effects model. Fifteen studies covering 609,054 participants were included. The pooled treatment rate for MDD in China was 19.5% (95% CI: 10.7%-28.4%). Among the 15 studies, 9 reported the number of patients who received treatments in psychiatric hospitals with a pooled treatment rate of 5.2% (95% CI: 2.8%-7.5%). Meta-regression found that study quality (ß = 0.131, P = 0.028) and male gender (ß = 0.006, P = 0.039) were significantly associated with a higher treatment rate for MDD. In China, the treatment rate for MDD, particularly in psychiatric hospitals, was low. Effective public education and increasing access to mental health services will probably increase the number of people seeking and receiving treatment.

BACKGROUND/AIMS: Schizophrenia is a severe psychiatric disorder, and complement 3 (C3) is closely related to schizophrenia. We investigated the association between C3 polymorphisms and schizophrenia in a Northeast Han Chinese population. METHODS: A total of 2240 Chinese people, consisting of 1086 patients with schizophrenia and 1154 healthy controls, were recruited for this study. Ten single nucleotide polymorphisms (SNPs; rs11569562, rs344555, rs2241393, rs2241392, rs11569514, rs445750, rs451760, rs11672613, rs2230205, and rs2250656) in C3 were selected and genotyped. RESULTS: Genotype distribution analysis indicated that rs11569514 was significantly associated with schizophrenia. In the dominant model (AA vs. GG+GA genotypes), we found a significant protective effect for rs344555 against schizophrenia (odds ratio [OR]: 0.72, 95% confidence interval [CI]: 0.53-0.99, P = 0.04). In the codominant model (TT vs. AA), we found a significant risk effect for rs11569514 on schizophrenia (OR: 4.39, 95% CI: 2.06-9.37, P < 0.001). Haplotypes, including TG (rs11569562 and rs344555), TGG (rs11569562-rs344555-rs2241393), AG (rs344555-rs2241393), CGGGT (rs11569562-rs344555-rs2241393-rs2241392-rs11569514), and ACGTG (rs11569514-rs445750-rs451760-rs11672613-rs2230205), showed either a risk or protective role for schizophrenia. CONCLUSIONS: SNP rs11569514 in C3 and haplotypes of C3 variants were associated with schizophrenia in a Han Chinese population.

The forkhead-box P2 (FOXP2) gene polymorphism has been reported to be involved in the susceptibility to schizophrenia; however, few studies have investigated the association between FOXP2 gene polymorphism and clinical symptoms in schizophrenia. This study investigated whether the FOXP2 gene was associated with the development and symptoms of schizophrenia in relatively genetically homogeneous Chinese population. The FOXP2 rs10447760 polymorphism was genotyped in 1069 schizophrenia inpatients and 410 healthy controls using a case-control design. The patients' psychopathology was assessed by the Positive and Negative Syndrome Scale (PANSS). We found no significant differences in the genotype and allele distributions between the patient and control groups. Interestingly, we found significant differences in PANSS total, positive symptom, and general psychopathology scores between genotypic subgroups in patients, with the higher score in patients with CC genotype than those with CT genotype (all p < 0.05). After adjusting demographic and clinical variables, the difference still remained significant for the PANSS positive symptom score and general psychopathology (both p < 0.05). Our findings suggest that the FOXP2 rs10447760 polymorphism may not contribute to the development of schizophrenia, but may contribute to the clinical symptoms of schizophrenia among Han Chinese.

BACKGROUND: Ghrelin, in humans, is a hormone secreted from the stomach with an orexigenic effect, which is good for digestion and absorption, as well as regulating physical growth, metabolism, and energy balance. It is also involved in the development of metabolic syndrome (MetS) and type 2 diabetes mellitus (T2DM). This study assessed the association between single nucleotide variants of the GHRL gene and the risk of metabolic syndrome in a Han Chinese population. METHODS: A case-control study was performed on 3780 Han Chinese comprising 1813 MetS cases and 1967 controls. Three missense polymorphisms in GHRL (rs26802, rs10490816, and rs696217) were selected, and the association between these polymorphisms and the risk of MetS was investigated. Metabolic syndrome was defined according to the criteria of the International Diabetes Federation (IDF). RESULTS: Using Pearson's ï£2 test, we found that there were no significant differences in genotype distributions and allele frequencies between cases and controls (all p > 0.05). There were also no significant differences in haplotype distributions between MetS cases and healthy controls. Furthermore, we confirmed that rs26802 of the GHRL gene is associated with body mass index (BMI), waist circumference, systolic blood pressure (SBP), and fasting glucose; rs10490816 is associated with triglycerides (TG) and total cholesterol (TC); while rs696217 is associated with hip circumference and fasting glucose. CONCLUSIONS: We concluded that mutations in the GHRL gene did not confer risk for MetS in our study population. Therefore, functional analysis and replication studies in other populations are needed to further investigate the exact role of the GHRL gene in MetS.

BACKGROUND: To evaluate the efficacy and safety of dendritic cells (DCs) co-cultured with cytokine-induced killer cell (CIK) immunotherapy combined with transcatheter arterial chemoembolization (TACE) or TACE plus local ablation therapy for hepatocellular carcinoma (HCC). METHODS: Our meta-analysis included a comprehensive search for relevant studies published through December 12, 2014. We used Cochrane Library, PubMed, CBM, VIP, CNKI, and Wanfang data. Depending on the heterogeneity among the included studies, we calculated the pooled odds ratio (OR) and mean difference (MD) using fixed- or random-effects models. Publication biases were assessed using funnel plots and Begg's tests. Sensitivity analyses were also performed. RESULTS: Seven randomized controlled trials (RCTs) and one controlled clinical trial (CCT) that included 693 patients and met the inclusion criteria were analyzed. Pooled results showed that DC-CIK immunotherapy combined with TACE or TACE plus local ablation therapy significantly improved 1-year (OR = 2.00, p = 0.02) and 2-year overall survival (OR = 1.77, p = 0.04). A favored overall response rate (ORR) (OR = 1.51, p = 0.03), disease control rate (DCR) (OR = 1.81, p = 0.01), and better quality of life (OR = 3.30, p < 0.01) were observed in the DC-CIK group. Additionally, when tumor-associated T lymphocyte subsets were compared, our analyses demonstrated that the percentage of CD3+ T cells (MD(CD3+) = 21.37, p = 0.005) and the ratio of CD4+/CD8+ (MD(CD4+/CD8+) = 2.83, p = 0.02) were significantly increased in the DC-CIK therapy group. CONCLUSIONS: The combination of DC-CIK immunotherapy and TACE or TACE plus local ablation therapy improves 1- and 2-year overall survival, ORR, DCR, and provides a better quality of life for patients with HCC.

Schizophrenia patients exhibit higher smoking rates than the general population. A growing body of evidence suggests that cigarette smoke impairs the antioxidant defense mechanisms, leading to oxidative damage. Manganese superoxide dismutase (MnSOD) is the major antioxidant in the mitochondria, catalyzing the metabolism of superoxide radicals to form hydrogen peroxide. Since the identification of a well-characterized functional polymorphism, Ala-9Val of MnSOD, a number of studies have evaluated the association between Val-9Ala and schizophrenia or cancer. In this study, we hypothesized that the functional polymorphism of MnSOD Ala-9Val was associated with smoking in patients with schizophrenia. This polymorphism was genotyped in 666 chronic male schizophrenia patients (smoker/never-smoker = 507/159) and 660 male controls (smoker/never-smoker = 360/300) using a case-control design. The cigarettes smoked per day (CPD) and smoking behaviors were evaluated by clinician-administered questionnaires and the Fagerstrom Test for Nicotine Dependence (FTND). The results showed no significant differences in MnSOD Ala-9Val genotype and allele distributions between the patients and healthy controls or between smokers and never-smokers in either patients or healthy controls alone. The smokers with the Ala allele started smoking significantly earlier (19.9 ± 5.8 vs. 21.7 ± 6.5 years, P = 0.005) only in patients. These results suggest that the MnSOD Ala-9Val polymorphism may not influence smoking status in a Chinese male schizophrenia population, but may influence the age at which smoking is started among schizophrenia smokers.

The influence of China's "one-child" policy on the mental health of children and adolescents is still unclear. This study examined the associations between number of children and children's mental health using data from the national school children and adolescents survey of China. Mental health was measured using the Achenbach's Child Behavior Checklist (CBCL). Linear regression models were used to explore the relationship between number of children per family and children's mental health. A total of 64,017 students were enrolled, with 68.60â¯% from one-child families. Compared with children from one-child families, those from multiple-children families had significantly higher scores on the total CBLC and each of its subscales (all P<0.001). Analyses suggested children from multiple-child families have a higher risk of mental health problems (total problems on the CBCL: adjusted B=2.217, 95â¯%CI=1.883-2.550, P<0.001). Regular mental health assessments should be implemented and effective interventions should be developed for those in need.
RESUMO
BACKGROUND: Exploring networks of mental and behavioral problems in children and adolescents may identify differences between one-child and multi-child families. This study compared the network structures of mental and behavioral problems in children and adolescents in one-child families versus multi-child families based on a nationwide survey. METHODS: Propensity score matching (PSM) was used to match children and adolescents from one-child families with those from multi-child families. Mental and behavioral problems were assessed using the Achenbach's Child Behavior Checklist (CBCL) with eight syndromal subscales. In the network analysis, strength centrality index was used to estimate central symptoms, and case-dropping bootstrap method was used to assess network stability. RESULTS: The study included 39,648 children and adolescents (19,824 from one-child families and 19,824 from multi-child families). Children and adolescents from multi-child families exhibited different network structure and higher global strength compared to those from one-child families. In one-child families, the most central symptoms were "Social problems", "Anxious/depressed" and "Withdrawn/depressed", while in multi-child families, the most central symptoms were "Social problems", "Rule-breaking behavior" and "Anxious/depressed". CONCLUSION: Differences in mental and behavioral problems among children and adolescents between one-child and multi-child families were found. To address these problems, interventions targeting "Social problems" and "Anxious/depressed" symptoms should be developed for children and adolescents in both one-child and multi-child families, while other interventions targeting "Withdrawn/depressed" and "Rule-breaking behavior" symptoms could be useful for those in one-child and multi-child families, respectively.
