Characterization of Depressive Symptoms Trajectories After Breast Cancer Diagnosis in Women in France

Long-term behavioral symptom clusters among survivors of early-stage breast cancer: Development and validation of a predictive model

BACKGROUND

Fatigue, cognitive impairment, anxiety, depression, and sleep disturbance are cancer-related behavioral symptoms that may persist years after early-stage breast cancer, affecting quality of life. We aimed to generate a predictive model of long-term cancer-related behavioral symptoms clusters among breast cancer survivors 4 years after diagnosis.

METHODS

Patients with early-stage breast cancer were included from the CANcer TOxicity trial (ClinicalTrials.gov identifier NCT01993498). Our outcome was the proportion of patients reporting cancer-related behavioral symptoms clusters 4 years after diagnosis (≥3 severe symptoms). Predictors, including clinical, behavioral, and treatment-related characteristics; Behavioral Symptoms Score (BSS; 1 point per severe cancer-related behavioral symptom at diagnosis); and a proinflammatory cytokine (interleukin 1b; interleukin 6; tumor necrosis factor α) genetic risk score were tested using multivariable logistic regression, implementing bootstrapped augmented backwards elimination. A 2-sided P less than .05 defined statistical significance.

RESULTS

In the development cohort (n = 3555), 642 patients (19.1%) reported a cluster of cancer-related behavioral symptoms at diagnosis, and 755 (21.2%) did so 4 years after diagnosis. Younger age (adjusted odds ratio for 1-year decrement = 1.012, 95% confidence interval [CI] = 1.003 to 1.020), previous psychiatric disorders (adjusted odds ratio vs no = 1.27, 95% CI = 1.01 to 1.60), and BSS (adjusted odds ratio ranged from 2.17 [95% CI = 1.66 to 2.85] for BSS = 1 vs 0 to 12.3 [95% CI = 7.33 to 20.87] for BSS = 5 vs 0) were predictors of reporting a cluster of cancer-related behavioral symptoms (area under the curve = 0.73, 95% CI = 0.71 to 0.75). Genetic risk score was not predictive of these symptoms. Results were confirmed in the validation cohort (n = 1533).

CONCLUSION

Younger patients with previous psychiatric disorders and higher baseline symptom burden have greater risk of long-term clusters of cancer-related behavioral symptoms. Our model might be implemented in clinical pathways to improve management and test the effectiveness of risk-mitigation interventions among breast cancer survivors.

Prevalence of depressive and anxiety symptoms in patients with head and neck cancer undergoing radiotherapy: A systematic review and meta-analysis of longitudinal studies

BACKGROUND AND PURPOSE

Patients with head and neck cancer (HNC) are particularly vulnerable to mental health concerns. Radiotherapy (RT) remains a key treatment modality for these malignancies, offering high chances of cure. However, the effects on mental health are not well defined. We aim to characterize longitudinally the prevalence and risk of depressive and anxiety symptoms over the course of RT in patients with HNC.

MATERIAL AND METHODS

A literature search was performed from database inception until November 1st, 2024. PROSPERO/MOOSE-compliant and pre-registered (PROSPERO:CRD42023441432) systematic review identified studies longitudinally reporting in patients with HNC undergoing curative intent RT. Pooled prevalence and odds ratio of clinically significant anxiety and depressive symptoms between different treatment timepoints were estimated using random-effects meta-analysis.

RESULTS

18 studies (total sample 1,920, mean age 59.9[SD = 3.17], 22.2 % female, 93.0 % white ethnicity) were included. Before RT, a pooled prevalence of depressive symptoms of 18.1 % (95 % confidence intervals [CI] = 13.1 %-24.4 %) was found. Short-term after completing RT (≤3 months), the prevalence of depressive symptoms peaked to 26.1 % (95 %CI = 18.9 %-35.0 %), decreasing in long-term (≥6 months) assessments to 16.4 % (95 %CI = 12.6 %-21.0 %). Anxiety symptoms continuously decreased from baseline (pooled prevalence 29.9 % [95 %CI = 27.3 %-32.7 %]) to 17.4 % (95 %CI = 12.1 %-24.5 %) in the long-term. Female and married patients showed higher prevalence of depressive symptoms. Those who underwent surgery showed a lower prevalence of anxiety symptoms.

CONCLUSIONS

High prevalence of clinically significant depressive and anxiety symptoms were found in patients with HNC undergoing RT, from baseline to long-term follow-up. The weeks following completion of RT are key, as depressive symptoms increase in this period. Screening and interventions prior to, during, and especially immediately post-RT would be beneficial.

Depression risk among breast cancer survivors: a nationwide cohort study in South Korea

BACKGROUND

Depression among breast cancer survivors is a significant concern affecting their long-term survivorship and quality of life. This study investigates the incidence of depression among breast cancer survivors and identifies associated risk factors.

METHODS

This retrospective cohort study used data from the Korean National Health Insurance Service database and included 59,340 breast cancer patients without a history of depression who underwent surgery between January 1, 2010, and December 31, 2016. They were individually matched 1:2 by age with a general population without cancer (n = 99,834). The mean follow-up period was 6.4 ± 2.6 years. Sub-distribution hazard ratios (sHRs) and 95% confidence intervals (CIs) were calculated considering death as a competing risk and adjusting for sociodemographic factors and comorbidities.

RESULTS

Breast cancer survivors with a mean (standard deviation) age of 51.5 (9.2) years had a 39% increased risk of depression compared to non-cancer controls (sHR 1.39, 95% CI 1.36-1.42). During the first year post-diagnosis, breast cancer survivors across all ages exhibited a significantly elevated risk of depression, with a sHR of 3.23 (95% CI 3.08-3.37). Notably, younger survivors had a sHR of 4.51 (95% CI 4.19-4.85), and older survivors had a sHR of 2.56 (95% CI 2.42-2.71). One year post-surgery, younger survivors (age ≤ 50 years) showed a 1.16-fold increase in depression risk (sHR 1.16, 95% CI 1.11-1.20), while older survivors (age > 50 years) showed no significant change in risk, which decreased over time. Use of anthracycline, taxane, or endocrine therapy was associated with an increased depression risk (sHR 1.17, 95% CI 1.13-1.22; sHR 1.12, 95% CI 1.07-1.16; and sHR 1.27, 95% CI 1.14-1.41, respectively), with endocrine therapy showing a 41% increased depression risk in older survivors (sHR 1.41, 95% CI 1.23-1.61).

CONCLUSION

This study demonstrates a significant association between breast cancer and depression, with a particularly heightened risk in younger survivors within the first year post-diagnosis. Special attention is needed to meticulously screen for depressive symptoms during the early follow-up years for breast cancer survivors who are premenopausal or have undergone chemotherapy and endocrine therapy.

Associations between health-related fitness and patient-reported symptoms in newly diagnosed breast cancer patients

BACKGROUND

Newly diagnosed breast cancer patients experience symptoms that may affect their quality of life, treatment outcomes, and survival. Preventing and managing breast cancer-related symptoms soon after diagnosis is essential. The purpose of this study was to investigate the associations between health-related fitness (HRF) and patient-reported symptoms in newly diagnosed breast cancer patients.

METHODS

This study utilized baseline data from the Alberta Moving Beyond Breast Cancer Cohort Study that were collected within 90 days of diagnosis. HRF measures included peak cardiopulmonary fitness (peak volume of oxygen consumption (VO2peak)), maximal muscular strength and endurance, flexibility, and body composition. Symptom measures included depression, sleep quality, and fatigue. Adjusted multivariable logistic regression was performed for analyses.

RESULTS

Of 1458 participants, 51.5% reported poor sleep quality, 26.5% reported significant fatigue, and 10.4% reported moderate depression. In multivariable-adjusted models, lower relative VO2peak was independently associated with a greater likelihood of all symptom measures, including moderate depression (p < 0.001), poor sleep quality (p = 0.009), significant fatigue (p = 0.008), any symptom (p < 0.001), and multiple symptoms (p < 0.001). VO2peak demonstrated threshold associations with all symptom measures such that all 3 lower quartiles exhibited similar elevated risk compared to the highest quartile. The strength of the threshold associations varied by the symptom measure with odds ratios ranging from ∼1.5 for poor sleep quality to ∼3.0 for moderate depression and multiple symptoms. Moreover, lower relative upper body muscular endurance was also independently associated with fatigue in a dose-response manner (p = 0.001), and higher body weight was independently associated with poor sleep quality in an inverted U pattern (p = 0.021).

CONCLUSION

Relative VO2peak appears to be a critical HRF component associated with multiple patient-reported symptoms in newly diagnosed breast cancer patients. Other HRF parameters may also be important for specific symptoms. Exercise interventions targeting different HRF components may help newly diagnosed breast cancer patients manage specific symptoms and improve outcomes.

Factor Structures in the Depressive Symptoms Domains in the 9Q for Northern Thai Adults and Their Association with Chronic Diseases

Most of the common models to examine depression are one-factor models; however, previous studies provided several-factor structure models on each depressive symptom using the Patient Health Questionnaire-9 (PHQ-9). The Nine-Questions Depression-Rating Scale (9Q) is an alternative assessment tool that was developed for assessing the severity of depressive symptoms in Thai adults. This study aimed to examine the factor structure of this tool based on the factor structure models for the PHQ-9 provided in previous studies using confirmatory factor analysis (CFA). We also examined the association of chronic diseases and depressive symptoms using the Multiple Indicators Multiple Causes model among 1346 participants aged 19 years old or more without psychiatric disorders. The results show that the two-factor CFA model with six items in the cognitive-affective domain and three items in the somatic domain provided the best fit for depressive symptoms in the study population (RMSEA = 0.077, CFI = 0.953, TLI = 0.936). Dyslipidemia was positively associated with both cognitive-affective symptoms (β = 0.120) and somatic depressive symptoms (β = 0.080). Allergies were associated with a higher level of cognitive-affective depressive symptoms (β = 0.087), while migraine (β = 0.114) and peptic ulcer disease (β = 0.062) were associated with a higher level of somatic symptoms. Increased age was associated with a lower level of somatic symptoms (β = -0.088). Our findings suggested that considering depressive symptoms as two dimensions yields a better fit for depressive symptoms. The co-occurrence of chronic diseases associated with depressive symptoms should be monitored.

Non-pharmaceutical interventions for depressive symptoms in patients with breast cancer: protocol for a systematic review and network meta-analysis

INTRODUCTION

Patients with breast cancer often suffer from depressive symptoms throughout various stages of cancer, significantly impacting their quality of life and treatment outcomes. Non-pharmaceutical interventions such as psychotherapy, mind-body therapies and physical exercise have shown effectiveness in addressing cancer-related depression. However, the efficacy and safety of different non-pharmacological interventions remain a topic of debate. Therefore, to provide an objective assessment and comparison of the impact of different non-pharmaceutical interventions on depression, we will conduct a network meta-analysis (NMA) to explore the effects of different non-pharmaceutical interventions on reducing depressive symptoms among patients with breast cancer.

METHODS AND ANALYSIS

We will search nine Chinese and English-language databases, from database inception to 31 July 2023, for randomised controlled trials published in Chinese or English. The English-language databases are PubMed, Medline, Embase, Web of Science and Cochrane Central Register of Controlled Trials, and the Chinese databases are CBM, CNKI, VIP and Wanfang. Two independent researchers will perform information extraction from eligible articles. The primary outcome will be the changes in depressive symptoms, while the secondary outcome will include adverse events. STATA V.15.0 will be used to conduct paired meta-analysis and NMA. Grading of Recommendations Assessment, Development and Evaluation will be used to assess the quality of evidence, and the Cochrane tool for assessing the risks of bias in randomised trials V.2 will be used for risk of bias assessment.

ETHICS AND DISSEMINATION

The study does not require ethical approval as it will analyse data from existing studies. It is expected that the results of the study will be published in peer-reviewed journals and presented at relevant conferences.

Perceived control, self-management efficacy, and quality of life in patients treated with radiation therapy for breast cancer: a longitudinal study

OBJECTIVE

This longitudinal study aims to examine the present state of perceived control, self-management efficacy, and overall quality of life (QoL) in patients with breast cancer undergoing radiotherapy, and gain insight into the dynamic trends and factors that influence the quality of life experienced by patients during the course of radiotherapy.

METHODS

Participants completed the Cancer Experience and Efficacy Scale (CEES), Strategies Used by People to Promote Health (SUPPH), and Functional Assessment of Cancer Therapy- Breast (FACT-B). The data was analyzed using the software SPSS26.0. Repeated measures analysis of variance (ANOVA) and mixed-effects linear models were used to analyze trends in perceived control, self-management efficacy, and QoL at three-time points, as well as factors affecting QoL during radiotherapy.

RESULTS

Perceived control and self-management efficacy were associated with QoL over the course of the radiotherapy. Self-management efficacy (β = 0.30, P < 0.001), presence of chemotherapy (β = 18.33, P = 0.024), and duration of illness (β = 2.25, P = 0.028) had a positive effect on the change in QoL, while time (β =  - 2.95, P < 0.001), cancer experience (β =  - 0.46, P < 0.001), and type of medical insurance (β =  - 2.77, P = 0.021) had the negative effect on the change in QoL.

CONCLUSION

The QoL, perceived control, and self-efficacy of patients with breast cancer show dynamic changes during radiotherapy. The higher the self-efficacy, the better the QoL, and the worse the QoL when the sense of disease control is poor. At the same time, more attention should be paid to the QoL of breast cancer radiotherapy patients with a long course of the disease, receiving chemotherapy, and different medical payment methods.

Ovarian Suppression: Early Menopause and Late Effects

OPINION STATEMENT

Around 90% of breast tumours are diagnosed in the early stage, with approximately 70% being hormone receptor-positive. The cornerstone of adjuvant therapy for early-stage hormone receptor-positive breast cancer is endocrine therapy, tailored according to disease stage, biological characteristics of the tumour, patient's comorbidities, preferences and age. In premenopausal patients with hormone receptor-positive breast cancer, ovarian function suppression is a key component of the adjuvant endocrine treatment in combination with an aromatase inhibitor or tamoxifen. Moreover, it can be used during chemotherapy as a standard strategy for ovarian function preservation in all breast cancer subtypes. In the metastatic setting, ovarian function suppression should be used in all premenopausal patients with hormone receptor-positive breast cancer to achieve a post-menopausal status. Despite its efficacy, ovarian function suppression may lead to several side effects that can have a major negative impact on patients' quality of life if not properly managed (e.g. hot flashes, depression, cognitive impairment, osteoporosis, sexual dysfunction, weight gain). A deep knowledge of the side effects of ovarian function suppression is necessary for clinicians. A correct counselling in this regard and proactive management should be considered a fundamental part of survivorship care to improve treatment adherence and patients' quality of life.

Trajectories and predictors of anxiety and depression among older cancer survivors: a nationally representative cohort study

PURPOSE

The study aimed to describe the long-term trajectories of anxiety and depression among older cancer survivors and examine sociodemographic and health-related predictors of different trajectories.

METHODS

Data were from the National Health and Aging Trends Study. Patient Health Questionnaire-4 was used to assess anxiety and depression. Group-based trajectory model was used to identify the distinct trajectories of anxiety and depression from 2015 to 2021. Design-based multinomial logistic regression was used to examine predictors of different trajectories. All analyses accounted for the complex sample design and survey weights.

RESULTS

A total of 1766 older cancer survivors were included representing 8.9 million older cancer survivors. The prevalence of anxiety and depression from 2015 to 2021 ranged from 25.12 to 29.11%. Four trajectories were identified: sustained low-risk (49.0%), deteriorating (24.1%), meliorating (11.0%), and sustained high-risk (16.1%). Potential predictors of high-risk anxiety and depression include older age, female, lower annual income, abnormal BMI, poorer self-rated health, more difficulty in activities of daily living (ADL), and worse cognitive function (P < 0.05).

CONCLUSIONS

The anxiety and depression progression patterns are heterogeneous among older cancer survivors. The trajectory affiliations could be predicted by sociodemographic and health-related factors, which have the potential to inform targeted clinical strategies (e.g., improve ADL and ameliorate cognitive function).

IMPLICATIONS FOR CANCER SURVIVORS

Anxiety and depression are common among older cancer survivors, and long-term trajectories identified by this study might help realize early-stage identification and individualized interventions for mental disorders.

Longitudinal trajectories of depression and quality of life in a cohort of cancer survivors and individuals without cancer in Europe

BACKGROUND

The long-term effects of cancer on psychological symptoms and quality of life (QoL) have been widely reported, but they were seldom examined over time compared to the general population.

AIMS

To investigate trajectories of depression and QoL over time among cancer survivors compared to individuals without cancer throughout Europe and identify associated factors.

METHODS

Data from five waves of the Survey of Health, Ageing and Retirement in Europe study were used. The study sample featured 1066 cancer survivors and 9655 individuals without cancer from 13 European countries. Group-based trajectory modeling was used to identify depression and QoL trajectories, and a linear mixed-effects model was used to characterize their correlates.

RESULTS

Four depression trajectories-stable low, stable high, increasing, and decreasing-and four QoL trajectories were identified. All QoL trajectories were stable over time, but differed in their levels: low, low-medium, medium-high, and high. Depression and QoL trajectories were similar between cancer survivors and individuals without cancer. However, significantly more cancer survivors had high-depression and low-QoL trajectories. Further, better perceived health, activities of daily living, physical activity, and income adequacy levels were significantly associated with changes in depression and QoL levels over time.

CONCLUSIONS

Although depression and QoL trajectories did not differ between cancer survivors and individuals without cancer, more cancer survivors were characterized by high-depression and low-QoL life trajectories.

IMPLICATIONS FOR CANCER SURVIVORS

Providers should be aware and screen for cancer survivors with elevated depression and low QoL, and promote relevant psychosocial interventions. Modifiable factors associated with depression and QoL can be targets for cancer survivors' long-term care plans.

Depressive symptom trajectories in older breast cancer survivors: the Thinking and Living with Cancer Study

PURPOSE

To identify trajectories of depressive symptoms in older breast cancer survivors and demographic, psychosocial, physical health, and cancer-related predictors of these trajectories.

METHODS

Recently diagnosed nonmetastatic breast cancer survivors (n = 272), ages 60-98 years, were evaluated for depressive symptoms (Center for Epidemiological Studies Depression Scale, CES-D; scores ≥16 suggestive of clinically significant depressive symptoms). CES-D scores were analyzed in growth-mixture models to determine depression trajectories from baseline (post-surgery, pre-systemic therapy) through 3-year annual follow-up. Multivariable, multinomial logistic regression was used to identify baseline predictors of depression trajectories.

RESULTS

Survivors had three distinct trajectories: stable (84.6%), emerging depressive symptoms (10.3%), and recovery from high depressive symptoms at baseline that improved slowly over time (5.1%). Compared to stable survivors, those in the emerging (OR = 1.16; 95% CI = 1.08-1.23) or recovery (OR = 1.26; 95% CI = 1.15-1.38) groups reported greater baseline anxiety. Greater baseline deficit accumulation (frailty composite measure) was associated with emerging depressive symptoms (OR = 3.71; 95% CI = 1.90-7.26). Less social support at baseline (OR = 0.38; 95% CI = 0.15-0.99), but greater improvement in emotional (F = 4.13; p = 0.0006) and tangible (F = 2.86; p = 0.01) social support over time, was associated with recovery from depressive symptoms.

CONCLUSIONS

Fifteen percent of older breast cancer survivors experienced emerging or recovery depressive symptom trajectories. Baseline anxiety, deficit accumulation, and lower social support were associated with worse outcomes.

IMPLICATIONS FOR CANCER SURVIVORS

Our results emphasize the importance of depression screening throughout the course of cancer care to facilitate early intervention. Factors associated with depressive symptoms, including lower levels of social support proximal to diagnosis, could serve as intervention levers.

Depression, Inflammation, and Intestinal Permeability: Associations with Subjective and Objective Cognitive Functioning throughout Breast Cancer Survivorship

About one-in-three breast cancer survivors have lingering cognitive complaints and objective cognitive impairment. Chronic inflammation and intestinal permeability (i.e., leaky gut), two risk factors for cognitive decline, can also fuel depression-another vulnerability for cognitive decline. The current study tested whether depression accompanied by high levels of inflammation or intestinal permeability predicted lower subjective and objective cognitive function in breast cancer survivors. We combined data from four breast cancer survivor studies (n = 613); some had repeated measurements for a total of 1015 study visits. All participants had a blood draw to obtain baseline measures of lipopolysaccharide binding protein-a measure of intestinal permeability, as well as three inflammatory markers that were incorporated into an inflammatory index: C-reactive protein, interleukin-6, and tumor necrosis factor-α. They reported depressive symptoms on the Center for Epidemiological Studies depression scale (CES-D), and a binary variable indicated clinically significant depressive symptoms (CES-D ≥ 16). The Kohli (749 observations) and the Breast Cancer Prevention Trial (591 observations) scales assessed subjective cognitive function. Objective cognitive function tests included the trail-making test, Hopkins verbal learning test, Conners continuous performance test, n-back test, FAS test, and animal-naming test (239-246 observations). Adjusting for education, age, BMI, cancer treatment type, time since treatment, study visit, and fatigue, women who had clinically elevated depressive symptoms accompanied by heightened inflammation or intestinal permeability reported poorer focus and marginally poorer memory. However, poorer performance across objective cognitive measures was not specific to inflammation-associated depression. Rather, there was some evidence of lower verbal fluency; poorer attention, verbal learning and memory, and working memory; and difficulties with visuospatial search among depressed survivors, regardless of inflammation. By themselves, inflammation and intestinal permeability less consistently predicted subjective or objective cognitive function. Breast cancer survivors with clinically significant depressive symptoms accompanied by either elevated inflammation or intestinal permeability may perceive greater cognitive difficulty, even though depression-related objective cognitive deficits may not be specific to inflammation- or leaky-gut-associated depression.

Implementing a PROACTive Care Pathway to Empower and Support Survivors of Breast Cancer

PURPOSE

Optimal comprehensive survivorship care is insufficiently delivered. To increase patient empowerment and maximize the uptake of multidisciplinary supportive care strategies to serve all survivorship needs, we implemented a proactive survivorship care pathway for patients with early breast cancer at the end of primary treatment phase.

METHODS

Pathway components included (1) a personalized survivorship care plan (SCP), (2) face-to-face survivorship education seminars and personalized consultation for supportive care referrals (Transition Day), (3) a mobile app delivering personalized education and self-management advice, and (4) decision aids for physicians focused on supportive care needs. A mixed-methods process evaluation was performed according to the Reach, Effectiveness, Adoption, Implementation and Maintenance framework including administrative data review, pathway experience survey (patient, physician, and organization), and focus group. The primary objective was patient-perceived satisfaction with the pathway (predefined progression criteria for pathway continuation ≥70%).

RESULTS

Over 6 months, 321 patients were eligible for the pathway and received a SCP and 98 (30%) attended the Transition Day. Among 126 patients surveyed, 77 (66.1%) responded. 70.1% received the SCP, 51.9% attended the Transition Day, and 59.7% accessed the mobile app. 96.1% of patients were very or completely satisfied with the overall pathway, whereas perceived usefulness was 64.8% for the SCP, 90% for the Transition Day, and 65.2% for the mobile app. Pathway implementation seemed to be positively experienced by physicians and the organization.

CONCLUSION

Patients were satisfied with a proactive survivorship care pathway, and the majority reported that its components were useful in supporting their needs. This study can inform the implementation of survivorship care pathways in other centers.

A long waiting time from diagnosis to treatment decreases the survival of non-small cell lung cancer patients with stage IA1: A retrospective study

Objective

The prognostic effect of delayed treatment on stage IA1 non-small cell lung cancer (NSCLC) patients is still unclear. This study aimed to explore the association between the waiting time before treatment and the prognosis in stage IA1 NSCLC patients.

Methods

Eligible patients diagnosed with pathological stage IA1 NSCLC were included in this study. The clinical endpoints were overall survival (OS) and cancer-specific survival (CSS). The Kaplan-Meier method, the Log-rank test, univariable, and multivariable Cox regression analyses were used in this study. Propensity score matching was used to reduce the bias of data distribution.

Results

There were eligible 957 patients in the study. The length of waiting time before treatment stratified the survival in patients [&lt;3 months vs. ≥3-months, unadjusted hazard ratio (HR) = 0.481, P = 0.007; &lt;2 months vs. ≥2-months, unadjusted HR = 0.564, P = 0.006; &lt;1 month vs. ≥1-month, unadjusted HR = 0.537, P = 0.001]. The 5-year CSS rates were 95.0% and 77.0% in patients of waiting time within 3 months and over 3 months, respectively. After adjusting for other confounders, the waiting time was identified as an independent prognostic factor.

Conclusions

A long waiting time before treatment may decrease the survival of stage IA1 NSCLC patients. We propose that the waiting time for those patients preferably is less than one month and should not exceed two months.

Determinants of depressive symptom trajectories in self-reported chronic obstructive pulmonary disease patients

BACKGROUND

The depressive symptom trajectories of COPD individuals and its' predictors remain to be established. Therefore, this study aimed to explore the trajectories of depressive symptoms and predictors thereof in COPD patients.

METHODS

A total of 1286 individuals over 45 years of age with self-reported COPD were assessed. Depressive symptoms were evaluated using the Center for Epidemiological Studies Depression Scale short form, with depressive symptom trajectories being identified via latent class growth analysis. The predictors of depressive symptom trajectories were then identified through multinomial logistic regression.

RESULTS

Finally, three depressive symptom trajectories were identified: "steadily high", "consistently moderate", and "consistently low". Old age, longer night-time sleep duration, and high BMI were found to be associated with individuals being classified under the "consistently moderate" trajectory. Moreover, participants exhibiting more than two chronic conditions were more likely to be classified under the "consistently moderate" trajectory. Higher education and lower hand grip strength were important predictors of individuals classified in the "steadily high" trajectory.

CONCLUSIONS

To conclude, three depressive symptom trajectories were identified in self-reported COPD individuals. To ensure timely intervention aimed at preventing the worsening of depressive symptom progression among COPD individuals, health-care workers should regular analyze depressive symptoms and provide appropriate interventions when possible.
