Comorbid depressive and anxiety symptoms and the risk of type 2 diabetes: Findings from the Lifelines Cohort Study

Childhood maltreatment and the risk of impaired glucose metabolism or type 2 diabetes in young adults: Findings from the Lifelines Cohort Study

We examined the associations between childhood maltreatment and the risk of impaired glucose metabolism (IGM) or type 2 diabetes (T2D) in young adults aged 18-35. Participants (N = 8506) from the Lifelines Cohort Study without IGM or diabetes at baseline (2007-2013) were included. Childhood maltreatment was assessed by the Childhood Trauma Questionnaire (CTQ) and incident IGM/T2D was assessed by haemoglobin A1c levels (≥5.7%) in 2014-2017. There were 223 (2.6%) cases of IGM/T2D during the follow-up period. After adjusting for sociodemographic and health/lifestyle covariates and follow-up time, only the CTQ Sexual Abuse subscale was significantly associated with IGM/T2D (RR = 1.05 [95% CI = 1.01, 1.10]). The association remained when additionally accounting for depressive and anxiety symptoms (RR = 1.05 [95% CI = 1.00, 1.09]). Childhood sexual abuse was associated with an increased risk of IGM/T2D in young adults, highlighting the long-term metabolic consequences of childhood maltreatment.

Socioeconomic disparities in the prevalence of depression and anxiety, and their associations with diabetes in rural southwest China

BACKGROUND

This study examines how the prevalence of depression and anxiety symptoms differ by socioeconomic status and explores their associations with diabetes in rural southwest China.

METHODS

Data were collected from a cross-sectional health interview and examination survey of 5,005 adults aged ≥ 35 years in rural southwest China. Height, weight, waist circumference, and fasting blood glucose measurement were taken. Depression and anxiety symptoms were assessed using Zung's Self-rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS), respectively. An individual socioeconomic position (SEP) index was constructed using principal component analysis.

RESULTS

The overall prevalence of depression, anxiety, comorbid depression and anxiety symptoms, and diabetes was 5.4%, 12.8%, 4.0%, and 9.6%, respectively. Females had higher prevalence of depression (7.3% vs. 3.4%, P < 0.01), anxiety (17.4% vs. 8.1%, P < 0.01), and comorbid depression and anxiety symptoms (5.8% vs. 2.3%, P < 0.01) than males. Han ethnicity participants had a higher prevalence of depression, anxiety, and comorbid depression and anxiety symptoms than ethnic minority participants (P < 0.01). Individuals with a lower education level and lower SEP were more likely to experience depression, anxiety, and comorbid depression and anxiety symptoms (P < 0.01), while individuals with good access to medical services were more likely to exhibit depression symptoms and comorbid depression and anxiety symptoms (P < 0.05). Multivariable logistic regression analysis found that individuals with depression symptoms (OR = 1.78, 95% CI: 1.25 to 2.53), anxiety symptoms (OR = 1.66, 95% CI: 1.30 to 2.16), and comorbid depression and anxiety symptoms (OR = 1.61, 95% CI: 1.07 to 2.44) all had a greater probability of having diabetes (P < 0.01); depression symptoms had the strongest association with diabetes prevalence (P < 0.01).

CONCLUSIONS

There are significant socioeconomic differences in the prevalence of depression and anxiety in rural southwest China, and both depression and anxiety symptoms have strong associations with diabetes. Future diabetes prevention and management strategies should focus on individuals with depression, anxiety, and comorbid depression and anxiety symptoms.

International guideline comparison of lifestyle management for acute coronary syndrome and type 2 diabetes mellitus: A rapid review

Acute coronary syndrome (ACS) is a life-threatening condition, with ACS-associated morbidity and mortality causing substantial human and economic challenges to the individual and health services. Due to shared disease determinants, those with ACS have a high risk of comorbid Type 2 diabetes mellitus (T2DM). Despite this, the two conditions are managed separately, duplicating workload for staff and increasing the number of appointments and complexity of patient management plans. This rapid review compared current ACS and T2DM guidelines across Australia, Canada, Europe, Ireland, New Zealand, the UK, and the USA. Results highlighted service overlap, repetition, and opportunities for integrated practice for ACS-T2DM lifestyle management across diet and nutrition, physical activity, weight management, clinical and psychological health. Recommendations are made for potential integration of ACS-T2DM service provision to streamline care and reduce siloed care in the context of the health services for ACS-T2DM and similar comorbid conditions.

Chronic insomnia, high trait anxiety and their comorbidity as risk factors for incident type 2 diabetes mellitus

The main objective of this study was to evaluate the association of the insomnia-anxiety comorbidity with incident type 2 diabetes (T2D) in a large prospective cohort. We selected adults without diabetes at baseline from the French NutriNet-Santé cohort who had completed the trait anxiety subscale of the Spielberger State-Trait Anxiety Inventory (STAI-T, 2013-2016) and a sleep questionnaire (2014); insomnia was defined according to established criteria. Using multivariable Cox models, we compared T2D risk across 4 groups: no insomnia or anxiety (reference), insomnia alone, anxiety alone (STAI-T ≥ 40), and comorbid anxiety and insomnia. Among 35,014 participants (mean baseline age: 52.4 ± 14.0 years; 76% women), 378 (1.1%) developed T2D over a mean follow-up of 5.9 ± 2.1 years. Overall, 28.5% of the sample had anxiety alone, 7.5%-insomnia alone, and 12.5%-both disorders. In the fully-adjusted model, a higher T2D risk was associated with anxiety-insomnia comorbidity (HR = 1.40; 95% CI 1.01, 1.94), but not with each disorder separately, compared to the group without insomnia or anxiety. The findings supported a positive association between anxiety-insomnia comorbidity and incident T2D among general-population adults. Future research using clinical diagnoses of mental disorders could confirm the findings and guide diabetes prevention programs.

Sleep Characteristics are Associated with Risk of Treated Diabetes Among Postmenopausal Women

OBJECTIVE

The purpose of this study was to determine whether sleep characteristics are associated with incidence of treated diabetes in postmenopausal individuals.

METHODS

Postmenopausal participants ages 50-79 years reported sleep duration, sleep-disordered breathing, or insomnia at baseline and again in a subsample 3 years later. The primary outcome was self-reported new diagnosis of diabetes treated with oral drugs or insulin at any time after baseline. Multivariable Cox proportional hazards models were used.

RESULTS

In 135,964 participants followed for 18.1 (± 6.3) years, there was a nonlinear association between sleep duration and risk of treated diabetes. Participants sleeping ≤5 hours at baseline had a 21% increased risk of diabetes compared with those sleeping 7 hours (adjusted hazard ratio [aHR] 1.21; 95% confidence interval [CI], 1.00-1.47). Those who slept for ≥9 hours had a nonsignificant 6% increased risk of diabetes compared with those sleeping 7 hours (aHR 1.06; 95% CI, 0.97-1.16). Participants whose sleep duration had decreased at 3 years had a 9% (aHR 1.09; 95% CI, 1.02-1.16) higher risk of diabetes than participants with unchanged sleep duration. Participants who reported increased sleep duration at 3 years had a risk of diabetes (HR 1.01; 95% CI, 0.95-1.08) similar to those with no sleep duration change. Participants at high risk of sleep-disordered breathing at baseline had a 31% higher risk of diabetes than those without (aHR 1.31; 95% CI, 1.26-1.37). No association was found between self-reported insomnia score and diabetes risk.

CONCLUSIONS

Sleep-disordered breathing and short or long sleep duration were associated with higher diabetes risk in a postmenopausal population.

Do differences in sport participation contribute to socioeconomic health inequalities? Evidence from the Lifelines cohort study on all-cause mortality, diabetes and obesity

Little is known about the role of sport participation in socioeconomic health inequalities. We studied the association between different aspects of sport participation with all-cause mortality, type 2 diabetes mellitus (T2DM) and obesity, including inequalities between socioeconomic subpopulations. Using the Dutch Lifelines cohort study (n = 84,230), we assessed the associations of sport participation, as well as the amount, intensity, type and number of sports, with all-cause mortality, T2DM and obesity in individuals. We studied the effect of sport participation on health outcomes within and between educational categories. Outcomes were compared with moderate to vigorous physical activity (MVPA). Sport participation was significantly associated with lower mortality (HR = 0.81), T2DM (HR = 0.70), and obesity (HR = 0.77). No significant additional effects of the amount or intensity of sport participation were found, while participating in teams sport was associated with significantly lower mortality (HR = 0.53) compared with other types of sport. These effects were similar among educational categories. Sport participation explained between 11% (T2DM and obesity) and 22% (mortality) of health inequalities between educational categories. This was more than twice the effect size of MVPA. The sensitivity analysis with net income as the socioeconomic indicator showed similar results. Our results suggest that to reduce socioeconomic differences in health, public health policies should focus on increasing sport participation in groups with a low socioeconomic status, rather than increasing the amount or intensity of sport participation, or MVPA in general.

The prevalence and clinical correlates of anxiety in Chinese patients with first-episode and drug-naïve major depressive disorder at different ages of onset

BACKGROUND

Major depressive disorder (MDD) with comorbid anxiety is very common and is associated with worse clinical outcomes. MDD patients at different ages of onset may have different clinical features and associated factors. The aim of this study was to investigate the prevalence of anxiety and related factors in MDD patients at different ages of onset.

METHODS

A total of 1718 first-episode and drug-naïve (FEDN) MDD patients were recruited. The cutoff point for early-adulthood onset (EAO) and mid-adulthood onset (MAO) was the first depressive episode before or after age 45 years. Clinical features (depressive, anxiety and psychiatric symptoms) and some metabolic parameters were collected.

RESULTS

There was no significant difference in the prevalence of anxiety between EAO patients (50.7 %) and MAO patients (55.7 %). For EAO patients, regression analysis showed that TSH levels, TgAb levels, and TC levels were significantly associated with anxiety. For MAO patients, regression analysis showed that anxiety was associated with HDL-c levels and impaired glucose metabolism. Furthermore, suicide attempts, psychotic symptoms, and depression severity were correlated with anxiety in both groups.

LIMITATIONS

Our cross-sectional study cannot explain the causal relationship between anxiety and related factors in MDD patients at different ages of onset.

CONCLUSIONS

This study revealed that the clinical characteristics and factors associated with anxiety in MDD patients differed according to age of onset, and therefore age of onset needs to be considered while treating anxiety.

Predicting suicide attempts among people with diabetes using a large multicenter electronic health records dataset

OBJECTIVE

People with diabetes have a higher risk of suicidal behaviors than the general population. However, few studies have focused on understanding this relationship. We investigated risk factors and predicted suicide attempts in people with diabetes using the Least Absolute Shrinkage and Selection Operator (LASSO) regression.

METHOD

Data was retrieved from Cerner Real-World Data™ and included over 3 million diabetes patients in the study. Least absolute shrinkage and selection operator regression was applied to identify associated factors. Gender-, diabetes-type-, and depression-specific LASSO regression models were analyzed.

RESULTS

There were 7764 subjects diagnosed with suicide attempts with an average age of 45. We found risk factors for suicide attempts in diabetes patients, such as being an American Indian or Alaska Native (β = 0.637), atypical agents (β = 0.704), benzodiazepines (β = 0.784), and antihistamines (β = 0.528). Amyotrophy had a negative coefficient for suicide attempts in males with diabetes (β = -2.025); in contrast, it had a positive coefficient in females with diabetes (β = 3.339). Using MAOI had a negative coefficient for suicide attempts in T1DM patients (β = -7.304). Aged less than 20 had a positive coefficient for suicide attempts in depressed (β = 2.093) and non-depressed patients with diabetes (β = 1.497). The LASSO model had 94.4% AUC and 87.4% F1 score.

CONCLUSIONS

To our knowledge, this is the first study using LASSO regression to identify risk factors for suicide attempts and diabetes. The shrinkage technique successfully reduced the number of variables in the model to improve overfitting. Further research is needed to study cause-and-effect relationships. The results may help providers identify high-risk groups of suicide attempters among diabetes patients.

Shared genetics of psychiatric disorders and type 2 diabetes:a large-scale genome-wide cross-trait analysis

BACKGROUND

Individuals with psychiatric disorders have elevated rates of type 2 diabetes comorbidity. Although little is known about the shared genetics and causality of this association. Thus, we aimed to investigate shared genetics and causal link between different type 2 diabetes and psychiatric disorders.

METHODS

We conducted a large-scale genome-wide cross-trait association study(GWAS) to investigate genetic overlap between type 2 diabetes and anorexia nervosa, attention deficit/hyperactivity disorder, autism spectrum disorder, bipolar disorder, major depressive disorder, obsessive-compulsive disorder, schizophrenia, anxiety disorders and Tourette syndrome. By post-GWAS functional analysis, we identify variants genes expression in various tissues. Enrichment pathways, potential protein interaction and mendelian randomization also provided to research the relationship between type 2 diabetes and psychiatric disorders.

RESULTS

We discovered that type 2 diabetes and psychiatric disorders had a significant correlation. We identified 138 related loci, 32 were novel loci. Post-GWAS analysis revealed that 86 differentially expressed genes were located in different brain regions and peripheral blood in type 2 diabetes and related psychiatric disorders. MAPK signaling pathway plays an important role in neural development and insulin signaling. In addition, there is a causal relationship between T2D and mental disorders. In PPI analysis, the central genes of the DEG PPI network were FTO and TCF7L2.

CONCLUSION

This large-scale genome-wide cross-trait analysis identified shared genetics andpotential causal links between type 2 diabetes and related psychiatric disorders, suggesting potential new biological functions in common among them.

Prediabetes and the risk of type 2 diabetes: Investigating the roles of depressive and anxiety symptoms in the Lifelines cohort study

AIMS

Depression and anxiety may increase the risk of progressing from prediabetes to type 2 diabetes. The present study examined the interactions between prediabetes status and elevated depressive and anxiety symptoms with the risk of type 2 diabetes.

METHODS

Participants (N = 72,428) were adults aged 40 years and above without diabetes at baseline from the Lifelines Cohort Study (58% female; mean age = 51.4 years). The Mini-International Neuropsychiatric Interview screened for elevated symptoms of major depressive disorder and generalized anxiety disorder. Glycated haemoglobin A1c (HbA_1c ) levels determined prediabetes status at baseline (2007-2013), and HbA_1c and self-reported diabetes diagnoses determined diabetes status at follow-up (2014-2017). Groups were formed for elevated depressive and anxiety symptoms, respectively, and prediabetes status at baseline (elevated depressive/anxiety symptoms with prediabetes, elevated depressive/anxiety symptoms alone, and prediabetes alone), and compared to a reference group (no prediabetes or anxiety/depression) on the likelihood of developing diabetes during the follow-up period.

RESULTS

N = 1300 (1.8%) participants developed diabetes. While prediabetes alone was associated with incident diabetes (OR = 5.94; 95% CI = 5.10-6.90, p < 0.001), the group with combined prediabetes and depressive symptoms had the highest likelihood of developing diabetes over follow-up (OR = 8.29; 95% CI = 5.58-12.32, p < 0.001). Similar results were found for prediabetes and anxiety symptoms (OR = 6.57; 95% CI = 4.62-9.33, p < 0.001), compared to prediabetes alone (OR = 6.09; 95% CI = 5.23-7.11, p < 0.001), though with a smaller effect. The interaction between depressive symptoms and prediabetes was synergistic in age-and-sex adjusted analyses.

CONCLUSIONS

Individuals with elevated depressive, and to some extent anxiety, symptoms in combination with prediabetes may represent a high-risk subgroup for type 2 diabetes.

A bidirectional relationship between diabetes mellitus and anxiety: A systematic review and meta-analysis

BACKGROUND

Due to the existence of inconsistencies in the evidence regarding the direction and extent of association between diabetes and anxiety disorders, the anxiety-diabetes comorbidity remains an issue of debate.

AIM

To estimate the proportion and risk of diabetes among individuals with anxiety disorder and vice versa.

METHODS

A systematic review was conducted using studies retrieved from databases and grey literature, with the last database search being conducted on April 15, 2021. The methodological rigor of studies was assessed using the National Institute of Health quality assessment tool. Prevalence and effect size (ES) estimates were pooled using a random effect model. Heterogeneity was assessed using the Higgins' I² statistical test, and subgroup analysis conducted.

RESULTS

We included 68 studies presenting data from 2,128,029 participants. The prevalence of anxiety disorders in diabetic patients was 28% (95% CI: 26%, 31%); however, subgroup analysis showed significant differences based on type of anxiety assessment scales, study location, and type of diabetes. The prevalence of diabetes among patients with anxiety disorders was 12% (95% CI: 9%, 16%). Patients with anxiety disorders were found to have a 19% higher risk of diabetes (pooled effect size (ES) = 1.19, 95% CI: 1.13, 1.26). Diabetic patients were found to have a 41% higher risk of developing anxiety disorders (ES = 1.41, 95% CI: 1.19, 1.62).

CONCLUSIONS

There is a higher risk of anxiety disorders in patients with diabetes mellitus and vice versa. It is recommended to screen diabetic patients for anxiety at initial diagnosis and follow-up visits. Similarly, patients with anxiety disorders should have regular screening for diabetes.

Depressive symptomology and cancer incidence in men and women: Longitudinal evidence from the HUNT study

BACKGROUND

Depressive symptoms and mood disorders are associated with a host of physical conditions. However, it is inconclusive whether depressive symptoms are also associated with cancer onset. The aim of this study was to investigate whether depressive symptoms are associated with cancer incidence in a large population-based sample of men and women.

METHODS

This study examined data from waves two (HUNT 2, 1995-97) and three (HUNT 3, 2006-08) of the Trøndelag Health Study (HUNT). Depressive symptoms were ascertained using the Hospital Anxiety and Depression Scale (HADS-D ≥ 8), cancer onset was identified via linkage with the Cancer Registry of Norway, death records by the national Cause of Death Register (CDR), and information on lifestyle and demographic factors was self-reported. Cox-proportional hazard regression models were used to test associations. Unadjusted, age-adjusted and multivariable best models accounting for smoking, education, marital status and current employment are presented.

RESULTS

Men and women (n = 61,985; 46.0 % men) were followed from baseline over a period of 778,802 person-years. During the 20-year study period, there were 6856 (11.1 %) individuals with incident cancers and 12,480 (20.1 %) deaths (n = 2498 attributed to cancer). For men with depressive symptoms, 505 (15.3 %) developed incident cancer during the follow-up period, whereas among those without depressive symptoms, 3164 (12.5 %) developed incident cancer. Following adjustment for age, depressive symptomology was not significantly associated with risk of overall cancer onset, nor among prostate, colon or melanoma subtypes. Depressive symptoms were associated with an increased risk of bronchus and lung cancer both before (HR 1.90, 95 % CI 1.43-2.50, p ≤0.001) and after adjustment for age (HR 1.38, 95 % CI 1.04-1.80, p = 0.025). However, further adjustment for additional possible confounders explained this association. For women with depressive symptoms, 384 (11.2 %) developed incident cancer during the follow-up period, whereas among those with no depressive symptomology, 2803 (9.3 %) developed incident cancer. After accounting for age, depressive symptomology was not associated with risk of overall cancer onset, nor among breast, colon, lung and bronchus, or melanoma subtypes. Additional analyses evaluating relationship of depression symptom severity and cancer onset did not alter findings for men or women.

LIMITATIONS

This report is limited by the post-hoc study design and subsequent non-randomised nature. Future prospective studies are required.

CONCLUSION

These results suggest that depressive symptoms are not associated with an increased risk of overall or site-specific cancer onset in these men and women. Given the increased co-occurrence of other medical conditions such as cardiovascular disease, diabetes, stroke and musculoskeletal disorders in people with depression, the role of clinically diagnosed depression and other psychiatric disorders in association with cancer onset necessitates further consideration.

Depressive symptoms in individuals diagnosed with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) in middle-aged and older Chinese individuals: Results from the China Health and Retirement Longitudinal Study

OBJECTIVES

Male lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) is common and may increase the risk of depressive symptoms. This study aimed to investigate the associated factors of LUTS/BPH and its association with depressive symptoms in middle-aged and older Chinese men.

METHODS

This study used data from the 2015 China Health and Retirement Longitudinal Study (CHARLS). A total number of 8,586 men aged ≥45 years were included in this study. Participants answered positively to whether they have ever been diagnosed with a prostate illness (excluding prostatic cancer) were defined as LUTS/BPH individuals. Depressive symptoms were assessed using the 10-item Center for Epidemiological Studies Depression Scale (CESD-10). Multivariate logistic analyses were applied to explore the associated factors of LUTS/BPH, association between LUTS/BPH and depressive symptoms, and risk factors of depressive symptoms according to LUTS/BPH status.

RESULTS

The weighted overall prevalence of LUTS/BPH was 13.1% in Chinese men aged ≥45 years. The prevalence of depressive symptoms was 29.1% in LUTS/BPH individuals and 22.9% in non-LUTS/BPH individuals. Depressive symptoms and LUTS/BPH shared some same risk factors, which were education, living regions, annual household consumption, sleep duration and multimorbidity. The results from logistic models showed that education, sleep duration and multimorbidity were significantly and independently associated with depression of LUTS/BPH individuals (P<0.001).

CONCLUSIONS

Prevalence of depressive symptoms in LUTS/BPH population was higher than in non-LUTS/BPH population. Education, sleep duration and multimorbidity were associated with the onset of depressive symptoms in LUTS/BPH individuals (P<0.001).

Depression and anxiety in patients with diabetes in a Moroccan region

AIMS

To estimate prevalence of anxiety and depression in patients with diabetes mellitus and identify their determinants.

METHODS

A cross-sectional study was conducted at Hassan II University-Hospital of Fes in 2019-2020. Anxiety and depression were measured by using the Hospital Anxiety and Depression Scale (HADS). Multivariate analysis by logistic regression was used to determine factors associated with depression and anxiety, adjusting for confounding factors. All statistical analyses were conducted using EPIINFO7.

RESULTS

A total of 243 diabetics were included in the study. The average age of the participants was 48.07±14.25 years, 58% were females and 72% were diagnosed with diabetes type II. The prevalence of depressive symptoms and anxiety symptoms was (18, 1%, CI_95%=(13-23)) and (29.6%, CI_95%=(24-35)), respectively. The prevalence of depression and anxiety was higher among women than man and increases with increasing duration of the disease. In multivariate analysis, illiterates (OR=3.19, CI_95%=(1.46-6.98)), those with depression (OR=3.61, CI_95%=(1.78-7.32)), and type 1 diabetics (OR=3.22, CI_95%=(1.44-7.21)) are a higher risk of developing anxiety. Depression was associated with older age (OR=2, 65, CI_95%=(1, 14-6, 14)), use of insulin (OR=3.77 CI_95%=(1.50-9.44)) and anxiety symptoms (OR=4, 27, CI_95%=(2, 05-8, 91)).

CONCLUSION

High prevalence of depressive and anxiety symptoms in diabetics suggests consideration of psychological aspect in implementation of diabetes managing program.

Mental Health among Spanish Adults with Diabetes: Findings from a Population-Based Case-Controlled Study

Background: The purpose of this study was to assess and compare the prevalence of self-reported mental disorders, psychological distress, and psychotropic drug consumption among people with diabetes mellitus (DM) and matched non-DM controls. Methods: A case–controlled study using data from the Spanish National Health Interview Survey was conducted in 2017. We identified 2116 DM adults (aged ≥35 years). Non-DM controls were matched 1:1 by age, sex, and province of residence. Results: Prevalence of mental disorders (25.0% vs. 19.2%; p < 0.001), psychological distress (29% vs. 19.5%; p < 0.001), and consumption of psychiatric medications (29.7% vs. 23.5%; p < 0.001) among DM cases were higher than those among matched non-DM controls. The DM patient variables associated with experiencing a mental disorder, psychological distress, and consumption of psychiatric medications were: being a woman, worse self-rated health, and a visit to a psychologist within the last year. Older age (≥80 years) was associated with a lower probability of reporting mental disorders and psychological distress among DM cases. Not practicing physical exercise was significantly associated with experiencing psychological distress. Conclusions: Adults with DM included in our investigation have a significantly higher prevalence of mental disorders, psychological distress, and consumption of psychiatric medications than non-DM controls. It is necessary to implement screening strategies and psychological interventions to improve the mental health of DM patients in Spain, focusing especially on women and those aged 35 to 59 years.

How is sport participation related to mortality, diabetes and prediabetes for different body mass index levels?

This study examined the association of sport participation with health outcomes and whether this relation differs between body mass index (BMI)‐level subpopulations. Research outcomes for sport participation were compared with other types of leisure‐time physical activity (PA). We used the Cox proportional hazards regression models to assess the associations of sport participation, and four other PA types (cycling, gardening, doing odd jobs, and walking), with the risk of prediabetes, type 2 diabetes mellitus (T2DM), and all‐cause mortality in 97,212 individuals (58.4% women; mean age: 46.5 years) in the Dutch LifeLines cohort. Outcomes were stratified by three BMI levels: healthy weight (BMI: 18.5‐24.9 kg/m²), overweight (BMI: 25.0‐29.9 kg/m²), and obesity (BMI: 30.0 kg/m² or above). Sport participation was associated with lower health risks, but only significantly so for prediabetes (HR = 0.86, 95% CI: 0.81‐0.92). For healthy weight persons, sport participation was associated with the largest risk reductions, with significantly lower risks of prediabetes (HR = 0.78, 95% CI: 0.68‐0.90) and all‐cause mortality (HR = 0.79, 95% CI 0.65‐0.96). Other PA types were not associated with significantly lower health risks, with the exception of cycling, for which significantly lower health risks for persons with overweight were found. Our findings show that sport participation is associated with lower health risks, especially prediabetes, but the effect varies between BMI levels, with the strongest link for persons with a healthy weight. Sport participation, together with cycling, is likely to be more effective in reducing health risks than other types of PA.

Antidepressants and Risk of Type 2 Diabetes Mellitus: A Population-Based Nested Case-Control Study

PURPOSE/BACKGROUND

The increased risk of type 2 diabetes mellitus (T2DM) among users of antidepressants (ADs) might be mediated by depression. We investigated whether ADs are associated with increased risk of T2DM in patients with depression. Moreover, the relationship between binding affinities of serotonin transporter (SERT) of ADs and the risk of T2DM is examined.

METHODS/PROCEDURES

We conducted a retrospective nested case-control study using data from Taiwan's National Health Insurance Research Database between 2000 and 2013. A total of 3038 patients with depression, 1519 cases of T2DM, and 1519 controls matched for age, sex, and index date, were included. Exposure to ADs was categorized by type and SERT. The association between AD exposure and T2DM development was assessed using conditional logistic regression analysis.

FINDINGS/RESULTS

No association between T2DM development and selective serotonin reuptake inhibitors (adjusted odds ratio [AOR], 1.01; 95% confidence interval [CI], 0.87-1.19; P = 0.962), serotonin-norepinephrine reuptake inhibitors (AOR, 1.13; 95% CI, 0.94-1.37; P = 1.196), tricyclic antidepressants (AOR, 1.01; 95% CI, 0.85-1.21; P = 0.906), or others (AOR, 0.88; 95% CI, 0.75-1.03; P = 0.104) was found. Alternatively, no association between individual ADs and potency of affinity to SERT and the risk of T2DM was found.

IMPLICATIONS/CONCLUSIONS

No association between ADs and increase risk of T2DM was found in patients with depression. However, regular metabolic evaluations are recommended for patients with depression regularly taking ADs.

Role of glucocorticoid receptor phosphorylation-mediated synaptic plasticity in anxiogenic and depressive behaviors induced by monosodium glutamate

Psychiatric diseases and metabolic disorders frequently cooccur, yet the mechanisms underlying this interaction remain unknown. The aim of this study was to determine the role of glucocorticoid receptor (GR) phosphorylation in the comorbidity of metabolic and psychiatric disorders. Neonatal Sprague-Dawley rats were subcutaneously injected with monosodium glutamate (MSG) every 2 days for 10 days after birth. Metabolic and behavioral tests were performed 12 weeks later. Golgi staining and transmission electron microscopy (TEM) were performed to evaluate synaptic structural plasticity. Changes in GR phosphorylation and the BDNF/TrkB pathway were evaluated by western blotting and immunofluorescence. We found that MSG-treated rats displayed significant metabolic abnormalities accompanied by anxiogenic and depressive behaviors, an altered synaptic ultrastructure and the loss of dendritic spines. The expression of phosphorylated GR was reduced in the brain. Furthermore, a specific agonist of BDNF/TrkB significantly reversed the reduction in GR phosphorylation, as well as the metabolic and behavioral outcomes. These findings indicate that a decrease in BDNF/TrkB pathway-dependent GR phosphorylation is a long-term effect of MSG treatment that may contribute to metabolic and behavioral disturbances.

Comorbid depressive and anxiety symptoms and frailty among older adults: Findings from the West China health and aging trend study

BACKGROUND

Depression and anxiety are two common mental disorders in older people. Studies have reported that depression is strongly associate with frailty, but few studies focus on anxiety disorder and comorbid two mental disorders. In this study, we aimed to identify associations between comorbid depressive and anxiety symptoms with frailty in older adults.

METHODS

4,103 community-dwellings adults aged 60 and older from the baseline of the West China Health and Aging Trend (WCHAT) study were included. Frailty was measured by the Fried frailty phenotype criteria. The 15-item Geriatric Depression Scale (GDS-15) and 7-item Generalized Anxiety Disorder Scale (GAD-7) assessed for depressive and anxiety symptoms with a cut-off value of 5. Multinomial logistic regression was used to explore the association between different depressive and anxiety status and frailty.

RESULTS

8.7% of old adults suffered comorbid depressive and anxiety symptoms in the present study. The prevalence of pre-frailty and frailty was 47.0% and 6.7%, respectively. After adjusting for covariates, individuals with comorbid depressive and anxiety symptoms had higher odds of being pre-frail (OR=1.86, 95% CI=1.41, 2.45) and frail (OR=7.03, 95% CI=4.48, 11.05) compared to those without depressive and anxiety symptoms. In the comorbidity group, those with severe comorbid symptoms also had higher prevalence of pre-frailty and frailty.

LIMITATIONS

Depressive and anxiety symptom assessments were based on screening tools.

CONCLUSIONS

This study suggested comorbid depressive and anxiety symptoms were associated with frailty among Chinese older adults. Further efforts to screen and target depression and anxiety comorbidity may be warranted.

Women with polycystic ovary syndrome associated with increased anxiety risk: A population-based cohort study in Taiwan

BACKGROUND

Polycystic ovary syndrome (PCOS) has been associated with developing mental disorders in Western populations, but this association is poorly studied in Asians. Hence, using insurance claims data, this study evaluated the anxiety risk in women with PCOS.

METHODS

Using Taiwan's National Health Insurance Research Database, we identified 7026 women aged 15-49 years with newly diagnosed PCOS without anxiety in 1998-2013 as the PCOS cohort. We also randomly selected 28,104 women without PCOS and anxiety as the comparison cohort, which was frequency-matched to cases by age and index year. Determined by incidence and Cox method, the hazard ratio (HR) of anxiety and the 95% confidence interval (CI) for the association with PCOS were estimated after a 16-year follow-up.

RESULTS

The incidence of anxiety was 19.5% higher in the PCOS cohort than in the comparison cohort (15.3 vs. 12.8 per 1000 person-years), with an adjusted HR of 1.18 (95% CI=1.07-1.30). For women with both PCOS and comorbid depression, it was 32.1 per 1000 person-years, with an adjusted HR of 2.24 (95% CI=1.24-4.06), compared with those without PCOS or depression. Moreover, it was 48.0 per 1000 person-years for women with depression alone (adjusted HR=3.46; 95% CI=2.58-4.64).

LIMITATIONS

We used a diagnostic code to identify PCOS cases without reference to pathology records. Miscoding might have occurred in the database.

CONCLUSIONS

PCOS is associated with an increased risk of developing anxiety independently. Comorbid depression could increase the risk further. Our findings provide vital information for Asian women to cope with anxiety.

The influence of personality on trajectories of distress, health and functioning in mild-to-moderately depressed adults with type 2 diabetes

Identification of mental health risk is important for optimising diabetes care in type 2 diabetes mellitus (T2DM). Personality is linked to diabetes health and may assist detection of individuals with T2DM most at risk of chronic mental health difficulties. This study examined the moderator effect of personality factors on changes in psychological distress and functioning in adults with T2DM and mild-to-moderate depressive symptoms across a 12-month period. Data were obtained from participants in a randomised controlled trial of adults with T2DM.  Participants completed measures of depression (Patient Health Questionnaire-9), anxiety (General Anxiety Disorder-7), general functioning (Work and Social Adjustment Scale), diabetes distress (Diabetes Distress Scale), and diabetes self-management (Self-Management Profile for Type 2 Diabetes) at baseline, 3-, 6- and 12-months. Glycaemic control (HbA1c) was measured at baseline, 6- and 12-months. Two hundred trial completers agreed to complete a personality inventory (Big Five Inventory). Low neuroticism was linked with reduced depression, anxiety, functional impairment and diabetes distress over the year. High extraversion was associated with decreased anxiety and functional impairment. High conscientiousness was linked to increased healthy eating. No personality trait moderated HbA1c levels. Personality screening may help identify mental health risk and guide medical carer approach in T2DM patients.

Possible role of GLP-1 in antidepressant effects of metformin and exercise in CUMS mice

BACKGROUND

Both depression itself and antidepressant medication have been reported to be significantly related to the risk of type 2 diabetes mellitus (T2DM). Glucagon-like peptide-1 (GLP-1), a treatment target for T2DM, has a neuroprotective effect. As an enhancer and sensitiser of GLP-1, metformin has been reported to be safe for the neurodevelopment. The present study aimed to determine whether and how GLP-1 mediates antidepressant effects of metformin and exercise in mice.

METHODS

Male C57BL/6 mice were exposed to chronic unpredictable mild stress (CUMS) for 8 weeks. From the 4th week, CUMS mice were subjected to oral metformin treatment and/or treadmill running. A videocomputerized tracking system was used to record behaviors of mice for a 5-min session. ELISA, western blotting and immunohistochemistry were used to examine serum protein concentrations, protein levels in whole hippocampus, protein distribution and expression in dorsal and ventral hippocampus, respectively.

RESULTS

Our results supported the validity of metformin as a useful antidepressant; moreover, treadmill running favored metformin effects on exploratory behaviors and serum corticosterone levels. CUMS reduced GLP-1 protein levels and phosphorylation levels of extracellular signal-regulated kinase 1/2 (ERK1/2), but increased protein levels of B-cell lymphoma 2-associated X-protein (BAX) in mice hippocampus. All these changes were restored by both single and combined treatment with metformin and exercise.

LIMITATIONS

We did not establish a causal relationship between GLP-1 expression and related signaling, using GLP-1 agonist and antagonist or knockout techniques.

CONCLUSIONS

Our findings have demonstrated that protein levels of pERK and BAX may be relevant to the role of GLP-1 in antidepressant effects of metformin and exercise, which may provide a novel topic for future clinical research.

Risk Factors and Prevalence of Suicide Attempt in Patients with Type 2 Diabetes in the Mexican Population

BACKGROUND

It has been proposed that the risk of death by suicide is higher in patients with diabetes than in the general population. Therefore, it is necessary to investigate the risk factors of suicidal behavior in patients with type 2 diabetes. The aim of the present study was to analyze the prevalence of suicide attempt and determine the risk factors of suicide attempt, in patients with type 2 diabetes in a Mexican population.

METHODS

Clinic characteristics, anthropometric measurements, biochemical levels, depression, and suicidal behavior were evaluated in 185 Mexican patients with type 2 diabetes. A multivariate logistic regression analysis was performed to find predictive factors of suicide attempt.

RESULTS

11.4% of patients reported previous suicide attempts n = 21). Younger patients (OR: 3.63, 95% CI: 1.29⁻10.19), having depression (OR: 3.33, 95% CI: 1.13⁻9.76) and normal BMI (OR: 3.14, 95% CI: 1.11⁻8.83), were predictive factors of suicide attempt. No other variables in the study showed statistical significance.

CONCLUSIONS

Our results showed a high prevalence of suicidal behavior in patients with type 2 diabetes. We found that younger age, depression and normal BMI could be risk factors of suicide attempt in these patients. Therefore, psychiatric interventions to prevent depression and suicidal behavior in this population are necessary. New studies using larger samples are necessary to replicate and confirm these results.
