Prevalence of and factors associated with alexithymia among patients with chronic obstructive pulmonary disease in China: a cross-sectional study.

BACKGROUND: Alexithymia is a common psychological disorder. However, few studies have investigated its prevalence and predictors in patients with chronic obstructive pulmonary disease (COPD). Therefore, we aimed to determine the prevalence and predictors of alexithymia in Chinese patients. METHODS: This cross-sectional study included 842 COPD patients to assess the prevalence and predictors of alexithymia using the 20-item Toronto Alexithymia Scale (TAS-20). We used the Hospital Anxiety and Depression Scale (HADS) to assess anxiety and depression, the modified British Medical Research Council dyspnea Rating Scale (mMRC) to assess dyspnea, St. George's Respiratory Questionnaire (SGRQ) to assess quality of life, and the age-adjusted Charlson comorbidity index (ACCI) to assess comorbidities. Alexithymia-related predictors were identified using univariate and multivariate logistic regression analyses. RESULTS: The prevalence of alexithymia in COPD patients was 23.6% (199/842). Multivariate analysis showed that age [odds ratio (OR) 0.886; 95% confidence interval (CI) 0.794-0.998], body mass index (OR 0.879; 95% CI 0.781-0.989), HADS-anxiety (OR 1.238; 95% CI 1.097-1.396), HADS-depression (OR 1.178; 95% CI 1.034-1.340), mMRC (OR 1.297; 95% CI 1.274-1.320), SGRQ (OR 1.627; 95% CI 1.401-1.890), ACCI (OR 1.165; 95% CI 1.051-1.280), and GOLD grade (OR 1.296; 95% CI 1.256-1.337) were independent predictors for alexithymia in patients with COPD. CONCLUSIONS: The prevalence of alexithymia was high in Chinese COPD patients. Anxiety, depression, dyspnea, quality of life, comorbidities, and disease severity are independent risk factors, and age and BMI are predictive factors for alexithymia in COPD patients.

Cognitive-behavioral therapy on psychological stress and quality of life in subjects with pulmonary tuberculosis: a community-based cluster randomized controlled trial.

BACKGROUND: Anxiety and depression are two common psychological disorders in patients with pulmonary tuberculosis. We aimed to explore the effects of cognitive-behavioral therapy (CBT) on psychological stress and quality of life in patients with pulmonary tuberculosis. METHODS: From September 2018 to November 2018, 20 communities (461 participants in total) were randomly assigned in an intervention or control group following a two-level cluster random design. The intervention group underwent CBT for 2 months, whereas the control group received routine follow-up. Anxiety, depression, and quality of life were assessed using the Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder questionnaire (GAD-7), and 36-Item Short-Form Health Survey (SF-36) scales, respectively. Comparisons between the two groups were conducted using independent samples t-tests, and differences between the two groups before and after treatment were analyzed using paired samples t-tests. RESULTS: There were a total of 454 participants in the final analysis. After 2 months of CBT intervention, the CBT group had a GAD-7 score that was 1.72 lower than the control group (1.47-1.99, p < 0.001), a PHQ-9 score of the CBT group that was 2.05 lower than that of the control group (1.74-2.37, p < 0.001). The CBT group had a total SF-36 score that was 10.7 lower than that of the control group (95% CI: 7.9-13.5, p < 0.001). In patients with different degrees of anxiety and depression, only those in the intervention group who had mild and moderate anxiety and depression symptoms showed a significant reduction in anxiety and depression scores following the intervention. CONCLUSIONS: CBT can relieve anxiety, and depression symptoms and increase the quality of life in subjects with pulmonary tuberculosis.

Validation of the Asia-Pacific colorectal screening score and its modified versions in predicting colorectal advanced neoplasia in Chinese population.

BACKGROUND: Colorectal cancer is one of the most common cancers in the world. Several studies suggest using the Asia-Pacific colorectal screening (APCS) score and its modified versions to select high-risk populations for early colonoscopy, but external validation remains rare, and which score should be selected for CRC screening in China is unclear. Validation of multiple scores in the same population might help to choose the best performing score. METHODS: We conducted a cross-sectional study under the framework of Cancer Screening Program in Urban China, data from asymptomatic colorectal cancer screening in Xuzhou was used to validate the APCS score, the colorectal neoplasia predict (CNP) score, the Korean colorectal screening (KCS) score, the Modified APCS score and the 8-point risk score in predicting colorectal advanced neoplasia (CAN). RESULTS: 1804 subjects were included in the analysis and 112 CAN (6.21%) was detected. In each score, the detection rate of CAN was higher in the high-risk group than in the non-high-risk group (P < 0.05), and the RR (95%C.I.) ranged 2.20 (1.50-3.22) [8-point risk] to 4.00 (2.41-6.65) [Modified APCS]. The c-statistics (95%C.I.) of the scoring systems ranged from 0.58 (0.53-0.62) [8-point risk] to 0.65 (0.61-0.69) [KCS]. The sensitivity (95%C.I.) of these systems ranged from 31.25 (22.83-40.70) [8-point risk] to 84.82 (76.81-90.90) [Modified APCS], while the specificity (95%C.I.) ranged from 43.50 (41.12-45.90) [Modified APCS] to 83.81 (81.96-85.53) [8-point risk]. Using the APCS scoring system as a comparator, the net reclassification improvement (NRI) of each modified version ranged from - 10.34% (95%C.I.: - 22.63 to 1.95%) [8-point risk] to 4.79% (95%C.I.: - 1.50% to 11.08) [KCS]. The colonoscopy resource load (95%C.I.) ranged from 9 [1-3] [8-point risk] to 11 [3-5] [APCS and Modified APCS]. CONCLUSIONS: The APCS score and its modified versions have certain ability to predict the risk of advanced neoplasia and reduce the resource load. The modified APCS score and the KCS score seemed the preferable systems to classify high risk subjects based on its high RR, sensitivity and predictive ability in the selected population. Future research could focus on adding risk factors or combining with laboratory test results to improve the predictive power of the scoring system.

Effects of expressive art therapy on health status of patients with chronic obstructive pulmonary disease: a community-based cluster randomized controlled trial.

BACKGROUND AND OBJECTIVE: This study was performed to investigate the effect of expressive art therapy (EAT) on the health status of patients with chronic obstructive pulmonary disease (COPD). METHODS: This community-based cluster randomized controlled trial involved patients with COPD from 16 communities in China. Participants received either EAT plus usual care (UC) or UC only. General practitioners were trained in EAT before the intervention. The primary outcomes were depression and anxiety symptoms, measured with the Hospital Anxiety and Depression Scale (HADS) and expressed as the HADS score for depression or anxiety (HADS-D or HADS-A, respectively). The secondary outcomes were the quality of life and dyspnoea, measured with the COPD assessment test (CAT). Dyspnoea was assessed using the modified Medical Research Council (mMRC) dyspnoea scale. Lung function was expressed as the forced expiratory volume in 1 s as a percentage of the predicted value [FEV1 (% pred)]. Outcome data were collected from all participants at baseline, 2 and 6 months. RESULTS: In total, 360 participants with COPD and comorbid depression were included in the analysis with the control group of 181 receiving UC only and the intervention group of 179 receiving EAT plus UC. The EAT group showed significantly greater improvement in the HADS-D and HADS-A scores than the UC group at 2 months (p < 0.0001 and p < 0.001, respectively) and 6 months (p < 0.001 for both). The CAT and mMRC scores were significantly lower in the EAT group than in the UC group at 2 and 6 months (p < 0.001 for all). The FEV1 (% pred) was significantly higher in the EAT group than in the UC group at 6 months (p < 0.01). CONCLUSION: General practitioners can deliver EAT interventions. EAT can effectively reduce anxiety and depression symptoms and dyspnoea, improve quality of life and improve the pulmonary function of patients with COPD.

Predictors and outcomes of obstructive sleep apnea in patients with chronic obstructive pulmonary disease in China.

BACKGROUND: "Overlap syndrome" refers to obstructive sleep apnea (OSA) combined with chronic obstructive pulmonary disease (COPD), and has poorer outcomes than either condition alone. We aimed to evaluate the prevalence and possible predictors of overlap syndrome and its association with clinical outcomes in patients with COPD. METHODS: We assessed the modified Medical Research Council dyspnea scale (mMRC), Epworth sleepiness scale (ESS), COPD assessment test (CAT), Hospital Anxiety and Depression Scale (HADS), Charlson Comorbidity Index (CCI), and STOP-Bang questionnaire (SBQ) and performed spirometry and full overnight polysomnography in all patients. An apnea-hypopnea index (AHI) ≥ 5 events per hour was considered to indicate OSA. Risk factors for OSA in COPD patients were identified by univariate and multivariate logistic regression analyses. RESULTS: A total of 556 patients (66%) had an AHI ≥ 5 events per hour. There were no significant differences in age, sex ratio, mMRC score, smoking index, number of acute exacerbations and hospitalizations in the last year, and prevalence of cor pulmonale between the two groups (all p > 0.05). Body mass index (BMI), neck circumference, CAT score, CCI, ESS, HADS, and SBQ scores, forced expiratory volume (FEV)1, FEV1% pred, FEV1/forced vital capacity ratio, and prevalence of hypertension, coronary heart disease, and diabetes were all significantly higher and the prevalence of severe COPD was significantly lower in the COPD-OSA group compared with the COPD group (p < 0.05). BMI, neck circumference, ESS, CAT, CCI, HADS, hypertension, and diabetes were independent risk factors for OSA in COPD patients (p < 0.05). SBQ could be used for OSA screening in patients with COPD. Patients with severe COPD had a lower risk of OSA compared with patients with mild or moderate COPD (ß = - 0.459, odds ratio = 0.632, 95% confidence interval 0.401-0.997, p = 0.048). CONCLUSION: Patients with overlap syndrome had a poorer quality of life, more daytime sleepiness, and a higher prevalence of hypertension and diabetes than patients with COPD alone. BMI, neck circumference, ESS, CAT, CCI, HADS, hypertension, and diabetes were independent risk factors for OSA in patients with COPD. The risk of OSA was lower in patients with severe, compared with mild or moderate COPD.

Effectiveness of cognitive behavior therapy for sleep disturbance and glycemic control in persons with type 2 diabetes mellitus: A community-based randomized controlled trial in China.

BACKGROUND: Poor sleep quality is a common clinical feature in patients with type 2 diabetes mellitus (T2DM), and often negatively related with glycemic control. Cognitive behavioral therapy (CBT) may improve sleep quality and reduce blood sugar levels in patients with T2DM. However, it is not entirely clear whether CBT delivered by general practitioners is effective for poor sleep quality in T2DM patients in community settings. AIM: To test the effect of CBT delivered by general practitioners in improving sleep quality and reducing glycemic levels in patients with T2DM in community. METHODS: A cluster randomized controlled trial was conducted from September 2018 to October 2019 in communities of China. Overall 1033 persons with T2DM and poor sleep quality received CBT plus usual care or usual care. Glycosylated hemoglobin A1c (HbAlc) and sleep quality [Pittsburgh Sleep Quality Index (PSQI)] were assessed. Repeated measures analysis of variance and generalized linear mixed effects models were used to estimate the intervention effects on hemoglobin A1c and sleep quality. RESULTS: The CBT group had 0.64, 0.50, and 0.9 lower PSQI scores than the control group at 2 mo, 6 mo, and 12 mo, respectively. The CBT group showed 0.17 and 0.43 lower HbAlc values than the control group at 6 mo and 12 mo. The intervention on mean ΔHbAlc values was significant at 12 mo (t = 3.68, P < 0.01) and that mean ΔPSQI scores were closely related to ΔHbAlc values (t = 7.02, P < 0.01). Intention-to-treat analysis for primary and secondary outcomes showed identical results with completed samples. No adverse events were reported. CONCLUSION: CBT delivered by general practitioners, as an effective and practical method, could reduce glycemic levels and improve sleep quality for patients with T2DM in community.

Effect of group cognitive behavioural therapy on psychological stress and blood glucose in people with type 2 diabetes mellitus: A community-based cluster randomized controlled trial in China.

OBJECTIVE: To assess whether group cognitive behavioural therapy (GCBT) delivered by general practitioners reduces anxiety and depression and improves glycaemic levels in adults with type 2 diabetes mellitus. METHODS: We conducted a community-based cluster randomized controlled trial in adults with type 2 diabetes mellitus from 48 communities in China. Participants received either GCBT plus usual care (UC) or UC only. General practitioners were trained in GCBT before intervention in the intervention group. The primary outcome was glycated haemoglobin (HbA1c ) concentration. Outcome data were collected from all participants at baseline, 2 months, 6 months and 1 year. The secondary outcomes were depression (Patient Health Questionnaire-9; PHQ-9) and anxiety (General Anxiety Disorder questionnaire; GAD-7). RESULTS: The GCBT group showed greater improvement in GAD-7 and PHQ-9 scores, respectively, than the UC group after 2 months post-baseline (T = -6.46, p < 0.0001; T = -5.29, p < 0.001), 6 months (T = -4.58, p < 0.001; T = -4.37, p < 0.001) and 1 year post-intervention (T = -3.91, p < 0.001; T = -3.57, p < 0.001). There was no difference in HbA1c values between the GCBT and UC groups at 2 months while the values were lower in the GCBT group at 6 months and 1 year (T = -6.83, p < 0.001; T = -4.93, p < 0.001, respectively). Subgroup analysis indicated a long-term effect of GCBT only for mild and moderate anxiety and mild depression groups. Similarly, HbA1c values reduced only in the mild and moderate anxiety and the mild depression groups. CONCLUSIONS: General practitioners can deliver GCBT interventions. GCBT plus UC is superior to UC for reducing mild/moderate anxiety and depression, and improving glycaemic levels. TRIAL REGISTRATION: Chinese clinical trials registration (ChiCTR-IOP-16008045).

Effects of cognitive behavioral therapy on sleep disturbances and quality of life among adults with type 2 diabetes mellitus: A randomized controlled trial.

BACKGROUND AND AIMS: Cognitive behavioral therapy (CBT) is recommended as the first-line nonpharmacotherapy for sleep complaints. However, there are no studies that tested CBT for improving sleep quality and increasing quality of life (QOL) in patients with type 2 diabetes mellitus (T2DM). Therefore, this study aims to test the effect of CBT on sleep disturbances and QOL in patients with T2DM. METHODS AND RESULTS: In total, 187 participants with T2DM and comorbid poor sleep quality were included in the analysis with the control group of 93 receiving usual care (UC) only and the intervention group of 94 receiving CBT with aerobic exercise plus UC, The Pittsburgh Sleep Quality Index (PSQI), the Diabetes-Specific Quality of Life Scale (DSQLS) and the glycated hemoglobin (HbA1C) values were collected at baseline, after the 2-month intervention, and 6 months of follow-up. The CBT group had 3.03 points lower PSQI scores (95% confidence interval [CI]: 2.07-4.00, P < 0.001) and 7.92 points lower total DSQLS scores (95% CI: 4.98-10.87, P < 0.001) than the control group after 6-month follow-up. No difference was found in HbAlc between the two groups (t = -0.47, P = 0.64) after 2-month intervention, while the CBT group had 0.89 units lower HbAlc (95% CI: 0.49-1.28, P < 0.001) than the control group after 6-month follow-up. CONCLUSION: CBT is effective for sleep disturbances and can also improve sleep quality, increase QOL, and decrease glycemic levels in participants with T2DM.

Screening and functional studies of long noncoding RNA in subjects with prediabetes.

BACKGROUND: In recent years, long noncoding RNAs (LncRNAs) have been found to play an important role in type 2 diabetes mellitus. However, research on the relationship between LncRNAs and prediabetes is still emerging. OBJECTIVES: The study aim was to screen differently expressed LncRNAs and understand their localization and function in patients with prediabetes. METHODS: We used microarray analysis to screen LncRNAs in prediabetes participants.To further clarify the localization and function of the expressed mRNAs, we used gene ontology analysis and pathway analysis. Then, internal validations were performed using individual quantitative real-time polymerase chain reaction (qRT-PCR) assays. RESULTS: We identified 55 differently expressed LncRNAs and 36 mRNAs in prediabetes participants comparing with controls. Gene ontology analysis indicated that the most enriched transcript terms were multicellular organismal process, plasma membrane, and binding. Pathway analysis indicated that the differently expressed mRNAs were involved in processes such as starch and sucrose metabolism, pantothenate and coenzyme A biosynthesis, and nicotinate and nicotinamide metabolism. The qRT-PCR results showed a trend consistent with the microarray results in 30 patients and 30 healthy controls. CONCLUSIONS: We found aberrantly expressed LncRNAs and mRNAs in prediabetes subjects, and demonstrated that these LncRNAs are involved in the entire prediabetes biological process.

Interaction of diabetes and smoking on stroke: a population-based cross-sectional survey in China.

OBJECTIVES: Diabetes and smoking are known independent risk factors for stroke; however, their interaction concerning stroke is less clear. We aimed to explore such interaction and its influence on stroke in Chinese adults. DESIGN: Cross-sectional study. SETTING: Community-based investigation in Xuzhou, China. PARTICIPANTS: A total of 39 887 Chinese adults who fulfilled the inclusion criteria were included. METHODS: Participants were selected using a multistage stratified cluster method, and completed self-reported questionnaires on stroke and smoking. Type 2 diabetes mellitus (DM2) was assessed by fasting blood glucose or use of antidiabetic medication. Interaction, relative excess risk owing to interaction (RERI), attributable proportion (AP) and synergy index (S) were evaluated using a logistic regression model. RESULTS: After adjustment for age, sex, marital status, educational level, occupation, physical activity, body mass index, hypertension, family history of stroke, alcohol use and blood lipids, the relationships between DM2 and stroke, and between smoking and stroke, were still significant: ORs were 2.75 (95% CI 2.03 to 3.73) and 1.70 (95% CI 1.38 to 2.10), respectively. In subjects with DM2 who smoked, the RERI, AP and S values (and 95% CIs) were 1.80 (1.24 to 3.83), 0.52 (0.37 to 0.73) and 1.50 (1.18 to 1.84), respectively. CONCLUSIONS: The results suggest there are additive interactions between DM2 and smoking and that these affect stroke in Chinese adults.

The prevalence of alcohol dependence and its association with hypertension: a population-based cross-sectional study4 in Xuzhou city, China.

BACKGROUND: To describe the prevalence of alcohol dependence and to explore the relationship between alcohol dependence and newly detected hypertension in China. METHODS: A multistage stratified cluster sampling method was used to obtain samples from February to June 2013. The Michigan Alcoholism Screening Test was used to estimate alcohol dependence level. A standard questionnaire measured other independent variables. Enumeration data were analyzed using chi-square; quantitative data were analyzed using t-tests. Spearman correlation analysis and multivariate logistic regression analysis were performed to identify the relationship between alcohol dependence and hypertension. RESULTS: The alcohol dependence rate was 11.56%; 22.02% of males (3854/17501) and 1.74% of females (324/18656) were classified as alcohol dependent. The newly detected hypertension rate was 9.46% (3422/36157). Significant associations were found between alcohol dependence levels and blood pressure (P < 0.01). Alcohol dependence was positively correlated with systolic blood pressure (r = 0.071, P < 0.01) and diastolic blood pressure (r = 0.077, P < 0.01) and was an independent risk factor for hypertension after adjusting for confounders (low alcohol dependence: odds ratio [OR] = 1.44, 95% confidence intervals [CI] = 1.14-1.81, P < 0.01; light alcohol dependence: OR = 1.35, 95% CI = 1.11-1.64, P < 0.01; medium alcohol dependence: OR = 1.83, 95% CI = 1.40-2.41, P < 0.01). CONCLUSION: Alcohol dependence was high and associated with hypertension. Health education and precautions against alcoholism should be implemented in Xuzhou city.

[Relationship between alcohol dependence and new detected hypertension in adult residents of Xuzhou city].

OBJECTIVE: To observe the relationship between alcohol dependence and new detected hypertension in adult residents of Xuzhou city. METHODS: Participants were sampled by stratified multi-stage randomly cluster sampling method from February 2013 to June 2013 among permanent residents aged 18 and more in Xuzhou city. The alcohol dependence was defined with Michigan Alcoholism Screening Test (MAST). Other information was obtained by questionnaire. Spearman correlation analysis and multivariate logistic regression analysis were performed to identify the relationship between alcohol dependence and new detected hypertension. RESULTS: The alcohol dependence rate was 11.56% on the whole cohort (n=36 157), and 22.02%(3 854/17 501) for male and 1.74%(324/18 656) for female(P<0.01). The new detected hypertension rate was 9.46%(3 422/36 157) in the whole cohort. The new detected hypertension rate increased in proportion with the severity of alcohol dependence (P<0.01). Spearman correlation analysis showed that alcohol dependence was positively correlated with systemic blood pressure(r=0.071, P<0.01) and diastolic blood pressure (r=0.077, P<0.01). After adjusting for gender, age, marital status, body mass index, smoking status, physical activity level, educational level, income level and region, multivariate logistic regression analysis showed that alcohol dependence was an independent risk factor for hypertension (low alcohol dependence: OR=1.44, 95%CI 1.14-1.81, P<0.01; light alcohol dependence: OR=1.35, 95%CI 1.11-1.64, P<0.01; medium alcohol dependence: OR=1.83, 95%CI 1.40-2.41, P<0.01). CONCLUSIONS: The alcohol dependence is an independent risk factor for new detected hypertension in adult residents of Xuzhou city. Intensive hypertension prevention and treatment strategies should be performed on this population based on our results.

[Interaction between quality and duration of sleep on the prevalence of type 2 diabetes].

OBJECTIVE: To explore the effects related to quality and duration of sleep and their interactions on the prevalence of type-2 diabetes (T2DM). METHODS: 9 622 people aged 18 years and over were recruited for our cross-sectional study during March 2013 to May 2013. Unconditional logistic regression was used to analyze the relationship between quality and duration of sleep on T2DM. Bootstrap was used to calculate the relative excess risk of interaction (RERI), the attributable proportion (AP) of interaction and the synergy index (SI). 95% confidence intervals (CI) of RERI, AP and SI were estimated. RESULTS: Concerning the comparison between cases and controls on both individual and total scores, other scores were all significantly different (P < 0.01), except for two items (time for falling asleep and drugs for hypnosis). The prevalence of T2DM in volunteers with poor sleeping quality was higher than that in volunteers with good sleeping quality (P < 0.01). Individuals with sleep duration <6 hours had a higher prevalence of T2DM, when compared with individuals with sleep duration of 6-8 hours (P < 0.01). After adjusting for age, gender, level of education, occupation, family history of diabetes, status on cigarette smoking, alcohol intake, physical activities and body mass index (BMI), the prevalence of T2DM appeared the highest in those with poor sleeping quality and short duration (OR = 4.78, 95% CI:3.32-6.99; P < 0.01), when compared with those who had good sleep quality and 6-8 h sleep duration. The risk of T2DM still increased in people who had poor sleep or long duration (OR = 1.92, 95% CI:1.18-3.31; P < 0.01). Values of RERI, AP and SI (with 95% CI) were 2.33 (1.23-8.79), 0.67(0.21-0.83) and 6.87 (2.33-10.75), respectively, for the interaction between poor sleep quality and short sleep duration, while 0.33 (-0.12-1.13), 0.17 (-0.03-0.51), 1.56 (0.76-2.74) for the interaction between good sleep quality and long sleep duration. CONCLUSION: Our results suggested that there were additive interactions between poor quality and shorter duration of sleep.

Salt intake, knowledge of salt intake, and blood pressure control in Chinese hypertensive patients.

A cross-sectional study involving 2502 subjects was conducted to evaluate salt intake, knowledge of salt intake, and blood pressure control in hypertensive patients. The blood pressure control rate was 33.5% among the hypertensive patients. Of the patients, 69.9% had salt intake higher than 6 g/d. Overall 35.0% knew the recommended salt intake, and 94.9% knew that "excess salt intake can result in hypertension." Altogether, 85.8% of patients had received health education related to a low-salt diet at some time. Patients who consumed less than 6 g/d of salt had a higher control rate than those who consumed more than 6 g/d (48.7% vs. 27.0%; χ(2) = 111.0; P < .001). Patients with knowledge of the recommended salt intake had a higher control rate than those without (45.8% vs. 26.9%; χ(2) = 91.3; P < .001). Our findings suggest a high salt intake and low blood pressure control rate among Chinese hypertensive patients. Knowledge of recommended salt intake is inappropriate for patients with education of a low-salt diet.
