Abstract
Aims/Background Obesity and depression frequently co-occur, and the relationship between them is bidirectional. Being obese or overweight increases the risk of depression, and conversely, depression increases the risk of obesity or overweight. Emerging clinical research has shown that probiotics may be effective in treating obesity and associated depression. Modulating gut microbiota with probiotics may improve obesity-related depression, but current evidence is inconsistent. Methods We systematically searched PubMed, EMBASE, Web of Science, and Cochrane Library for randomized controlled trials examining probiotics for depression in obese adults. Mean difference (MD) in depression scores between probiotic and placebo groups was pooled across studies using random-effects models. Heterogeneity was assessed using I2 to explain heterogeneity in meta-regression analysis. To detect the publication bias of the included studies, a funnel plot, and Begg and Egger tests, were used. Possible heterogeneity moderators were detected by subgroup and sensitivity analyses, Galbraith plot, and graphic display of study heterogeneity (GOSH) analysis. Leave-one-out and Influence analyses were performed to assess sensitivity. Results Five trials (n = 488) were included. Overall, probiotics did not significantly improve depressive symptoms versus placebo (MD = 0.08, 95% confidence interval [CI] = -0.63 to 0.79, p = 0.82). Considerable heterogeneity among studies was observed (I2 = 63%). In subgroup analyses, probiotics significantly reduced depression as measured by the Edinburgh Postnatal Depression Scale (MD = -0.60, 95% CI = -1.17 to -0.03, p = 0.04) with no heterogeneity (I2 = 0%). Probiotics also decreased depressive symptoms after 12 weeks of supplementation (MD = -0.78, 95% CI = -1.58 to -0.01, p = 0.05) versus placebo. No publication bias was found using Begg and Egger tests. The GOSH diagnostics revealed three outliers, among the clusters identified by K-means, DBSCAN (Density-based spatial clustering of applications with noise algorithm), and GMM (Gaussian Mixture Model) analyses. Conclusion Overall, probiotics did not improve depressive symptoms in obesity. However, beneficial effects were observed with the Edinburgh Postnatal Depression Scale and short-term use of probiotic. Additional rigorous randomized controlled trials are warranted to elucidate the therapeutic potential of probiotics for obesity-related depression.

[PMID: 39262994 PMCID: PMC11388570 DOI: 10.1016/j.heliyon.2024.e36285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 08/12/2024] [Accepted: 08/13/2024] [Indexed: 09/13/2024] Open
Abstract
Objective This cross-sectional study examined the influence of sedentary behavior (SB) time substitution with physical activity (PA) on depressive symptoms among adults with overweight/obesity. SB time was replaced with equal amount of walking/bicycling or leisure-time moderate-to-vigorous PA (MVPA). Methods Data of the 18344 adults, who were overweight and obesity was obtained from the National Health and Nutrition Examination Survey 2006-2018. PA of participants was measured by the Global Physical Activity Questionnaire. Depressive symptoms, including overall, somatic, and cognitive depressive symptoms were assessed by the Patient Health Questionnaire-9 (PHQ-9). Isotemporal substitution model based on weighted multiple linear regression was used to assess the association of SB time substitution with PA on depressive symptoms. Results Independent model analysis showed that 30 min/day SB time was significantly associated with higher PHQ-9 depressive symptoms, while engage in walking/bicycling or leisure-time MVPA for 30 min/day was associated with lower depressive symptoms. Isotemporal substitution analyses revealed that replacing 30 min/day SB time with equal amount of walking/bicycling or leisure-time MVPA was associated with significant lower PHQ-9 total scores (walking/bicycling: β = -0.088, 95%CI = -0.129, -0.047, P < 0.01; MVPA: β = -0.160, 95%CI = -0.185, -0.134, P < 0.01). Moreover, cognitive depressive symptoms (walking/bicycling: β = -0.035, 95%CI = -0.058, -0.013, P < 0.01; MVPA: β = -0.074, 95%CI = -0.088, -0.060, P < 0.01), and somatic depressive symptoms (walking/bicycling: β = -0.053, 95%CI = -0.075, -0.030, P < 0.01; MVPA: β = -0.085, 95%CI = -0.100, -0.071, P < 0.01) were also significantly lower after replacing SB time with either walking/bicycling or MVPA. However, replacing 30 min/day PA with SB time represented with higher depressive symptoms. Conclusions Replacing SB time with walking/bicycling or MVPA is beneficial in lowering the depressive symptoms among overweight/obese adults. Owing to the benefits of PA on depression, strategies promoting PA participation, are necessary for better social/mental well-being and healthy society.

Prevalence and risk factors of thyroid dysfunction in outpatients with overweight or obese first-episode and drug-naïve major depressive disorder. J Affect Disord 2023; 328:135-140. [PMID: 36806659 DOI: 10.1016/j.jad.2023.02.068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 02/06/2023] [Accepted: 02/15/2023] [Indexed: 02/21/2023]
Abstract
BACKGROUND Thyroid dysfunction is common in patients with major depressive disorder (MDD). However, few studies have examined risk factors for thyroid dysfunction in overweight or obese first-episode and drug-naïve (FEDN) MDD patients. This study aimed to investigate the prevalence and risk factors of thyroid dysfunction in FEDN MDD patients with comorbid high body mass index (BMI). METHODS A total of 1718 FEDN MDD patients were included. Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), and Positive and Negative Syndrome Scale (PANSS) positive subscale were used to assess the clinical symptoms of the patients. In addition, metabolic parameters and thyroid hormone levels were measured. RESULTS The prevalence of thyroid dysfunction was approximately 1.75 times higher in MDD patients with comorbid overweight or obesity (72.3 %) than in patients without high BMI (58.8 %). The HAMD score, HAMA score, systolic blood pressure (BP), fasting blood glucose (FBG), thyroid peroxidase antibody (TPOAb), total cholesterol (TC), high-density lipoprotein (HDL-C), and low-density lipoprotein (LDL-C), were risk factors for thyroid dysfunction in MDD patients with high BMI. The combination of HAMD, FBG, TC, LDL-C, and systolic BP had a high AUC value of 0.76 differentiating patients with and without thyroid dysfunction. LIMITATION Causality cannot be drawn due to cross-sectional design. CONCLUSIONS This study demonstrated a high prevalence of thyroid dysfunction in FEDN MDD patients with high BMI. Severity of depression and anxiety, levels of systolic BP, FBG, TPOAb, TC, HDL-C and LDL-C appear to be associated with thyroid dysfunction in FEDN MDD patients with high BMI.

Abstract
BACKGROUND We aimed to explore the relationship between body mass index (BMI) and body weight perception (BWP) with suicidal behaviors among mainland Chinese adolescents. METHODS A nationally representative sample (N = 10 110) of Chinese adolescents was assessed in this study. Suicidal behaviors (ideation, plan and attempt) were evaluated by four self-reported questions. Generalized linear mixed model was used to estimate the adjusted odds ratios (ORs) for the association between BWP/BMI with suicidal behaviors. RESULTS The prevalence of suicidal ideation, suicidal plan and suicidal attempt was 12, 5 and 2.1%, respectively. After adjusting potential covariates, perceiving oneself as obese was significantly associated with increased risks of suicidal ideation (OR: 2.4, 95% confidence intervals, CI: 1.6-4.0, P = 0.001), suicidal plan (OR: 3.1, 95% CI: 1.5-6.3, P = 0.002) and suicidal attempt (OR: 3.7, 95% CI: 1.5-9.1, P = 0.001) compared with perceiving as normal weight among male adolescents; the effect attenuated to null among female adolescents. Perceiving oneself as underweight and overweight both exhibited significant adverse effect on suicidal behaviors (only suicidal ideation and suicidal plan) compared with perceiving oneself as normal weight among male adolescents, but not among female adolescents. The actual measured BMI was not significantly associated with suicidal behaviors among neither gender. CONCLUSIONS Self-perception of their body image rather than actual measured weight may have a gender-specific adverse effect on suicidal behaviors among Chinese adolescents.

Abstract
Background: Reduction in cerebral blood flow (CBF) plays an essential role in the cognitive impairment and dementia in obesity. However, current conclusions regarding CBF changes in patients with obesity are inconsistent. Objective: A systematic review and meta-analysis was performed to evaluate the relationship between obesity and CBF alterations. Methods: We systematically screened published cross-sectional and longitudinal studies focusing on the differences in CBF between obese and normal-weight individuals. Eighteen studies including 24,866 participants, of which seven articles reported longitudinal results, were evaluated in the present study. Results: The results of the meta-analysis showed that in cross-sectional studies, body mass index (BMI) was negatively associated with CBF (β= –0.31, 95% confidence interval [CI]: –0.44, –0.19). Moreover, this systematic review demonstrated that obese individuals showed global and regional reductions in the CBF and increased CBF in diverse functional areas of the frontal lobe, including the prefrontal cortex, left frontal superior orbital, right frontal mid-orbital cortex, and left premotor superior frontal gyrus. Conclusion: Our findings suggest that BMI, rather than waist circumference and waist-to-hip ratio, is inversely associated with CBF in cross-sectional studies. The CBF of obese individuals showed global and regional reductions, including the frontal lobe, temporal and parietal lobes, cerebellum, hippocampus, and thalamus.

Abstract
The objectives of this paper were to examine the risk of depression and depressive symptoms among Han and minority children and adolescents in rural China, the links between academic performance and depressive symptoms, and the prevalence of these links among specific subgroups. A total of 8392 4th, 5th, and 6th grade students at 105 sample rural schools in eight low-income counties and districts in a prefectural-level city in Southwestern China were randomly selected using a three-step sampling strategy. A total of 51% of the sample were female (SD = 0.50), and the age range was 7 to 19 years (mean = 11.35 years; SD = 1.05). Using the Patient Health Questionnaire 8-item depression scale, the prevalence of depressive symptoms in the sample was assessed, while data on students' academic performance (standardized math test) and demographic characteristics were also collected. Our results show that the rates of major depression were 19% for Han students, 18% for Tibetan students, and 22% for Yi students; the rates of severe depression were 2% for Han and Tibetan students, and 3% for Yi students. Yi students were at significantly higher risks for major and severe depression than Han students. We conducted multivariate regression and heterogeneous analyses. Academic performance was negatively and significantly correlated to depressive symptoms. Across the whole sample, students with lower math scores, minority students, boys, younger students, and students with migrant parents were most vulnerable to depressive symptoms. The heterogeneous analysis suggests that among poor-performing students, subgroups at higher risk for depression include boys, non-boarding students, and students whose mothers had graduated from high school or above. These findings indicate a need to improve mental health outcomes of rural Han and minority primary school students, targeting academic performance for possible intervention.

Perceived academic stress and depressive symptoms among Chinese adolescents: A moderated mediation analysis of overweight status. J Affect Disord 2022; 296:224-232. [PMID: 34614439 DOI: 10.1016/j.jad.2021.09.060] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Revised: 09/17/2021] [Accepted: 09/21/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND Previous research has indicated the association of perceived stress with mental health problems. In China, Confucian collectivism and an exam-centered culture encourage parents to have high educational expectations that impose great pressure on their children's learning. However, limited research has focused on adolescents' perceptions of the negative consequences of academic stress stemming from their parents' educational expectations. This study addressed this research gap by examining the direct effect of adolescents' perceptions of academic stress on their depressive symptoms and the indirect effects of both parent-child communication and interaction. We further explored the pathway differences between overweight and non-overweight adolescents. METHODS By using a sample (n = 6,566) from the first two waves of the China Education Panel Survey, moderated mediation analysis was performed to simultaneously analyze the mediating roles of parent-children communication and parent-children interaction and the moderating role of adolescent overweight status. RESULTS Adolescents' perceived academic stress (W1) was positively associated with their depressive symptoms (W2). This association was partially mediated by both parent-child communication (W1) and parent-child interaction (W1). Moreover, adolescent overweight status significantly moderated the paths between the adolescents' perceived academic stress and their depressive symptoms, between their perceived academic stress and parent-child interaction, and the indirect relationship via parent-child interaction. LIMITATIONS Some measurement biases including self-reported, unverified, and single-item measures, alongside not considering all variations in controlled variables should be noted. CONCLUSION The study's findings identify the significant roles of parent-child communication and parent-children interaction in contemporary China and indicate overweight adolescents' susceptibility to stress.

Abstract
Psychological factors may explain why some people develop obesity and others remain a normal weight during their life course. We use an umbrella review approach to build an evidence-based map of the psychological correlates of heavier body weight. Synthesising findings from 42 meta-analyses that have examined associations between psychological factors and heavier body weight, we assessed level of evidence for a range of cognitive, psychosocial and mental health individual difference factors. There is convincing evidence that impaired mental health is associated with heavier body weight and highly suggestive evidence that numerous cognitive factors are associated with heavier body weight. However, the relatively low methodological quality of meta-analyses resulted in lower evidential certainty for most psychosocial factors. Psychological correlates of heavier body weight tended to be small in statistical size and on average, people with obesity were likely to be more psychologically similar than different to people with normal weight. We consider implications for understanding the development of heavier body weight and identifying effective public health interventions to reduce obesity.

Abstract
BACKGROUND Clinical depression (including major depression, dysthymia, and unspecified depression) is common in children and adolescents with obesity and overweight. The objective of this systematic review and meta-analysis was to examine prevalence of clinical depression among overweight and obese children. METHODS PubMed, EMBASE, Web of Science, Medline, Cochrane library, and PsycINFO databases were systematically and independently searched by three researchers from the inception dates to April 01, 2019. The fixed-effects model was used to perform meta-analysis. Data analyses were performed with STATA Version 12.0. RESULTS Eleven studies with 69,893 subjects were included; 5 studies examined major depressive disorder (MDD), while the remaining 6 studies examined other types of clinical depression. In the overweight and obese group, the prevalence of clinical depression ranged from 1.7% to 26.7% in obese subjects and from 4.0% to 16.9% in overweight subjects. In studies on MDD, prevalence ranged from 10.1% to 26.7% in obese subjects and from 9.0% to 16.9% in overweight subjects. The odd ratios (ORs) of clinical depression ranged from 0.92 to 4.39 between obese subjects and healthy controls (i.e., normal-weight controls), and ranged from 0.96 to 1.67 between overweight subjects and controls. Compared to healthy controls, obese (OR = 1.851, 95% CI: 1.410-2.429) but not overweight (OR = 1.068, 95% CI: 0.889-1.283) children and adolescents were more likely to have MDD. CONCLUSION Obese children and adolescents had a significantly higher risk for MDD compared with healthy controls. Considering the negative health outcomes of depression, regular screening and effective treatments should be implemented for obese children and adolescents.
