Chu YC, Yang CC, Chen SJ, Cheng PL, Wu MC, Wu HH, Lai CY. The Gender Gap in the Relationship between Metabolic Syndrome and Restrictive Ventilatory Defects. Nutrients 2024; 16:2548. [PMID: 39125427 PMCID: PMC11314350 DOI: 10.3390/nu16152548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2024] [Revised: 07/24/2024] [Accepted: 08/01/2024] [Indexed: 08/12/2024] Open
Abstract
BACKGROUND Given the fundamental physiological differences between the sexes, this study aimed to investigate the effect of metabolic syndrome on ventilatory defects stratified by sex. METHODS We conducted a nationwide, pooled, cross-sectional study. Data from 45,788 participants (men, n = 15,859; women, n = 29,929) aged 30 years or more were obtained from the Taiwan Biobank. Age-sex-adjusted and multivariate logistic regression models were used to estimate the risk of developing impaired pulmonary function (restrictive or obstructive ventilatory defects) in individuals with or without metabolic syndromes. Separate models were also used to estimate the effect of metabolic syndrome scores and the effect of individual metabolic abnormalities on the risk of restrictive ventilatory defects. RESULTS The overall prevalence of metabolic syndrome was estimated to be 15.9% in Taiwan, much higher in men than in women (18.6% versus 14.4%). A significant association was observed between metabolic syndromes and the risk of restrictive ventilatory defects. The risk of developing a restrictive ventilator defect was 35% higher in participants with metabolic syndromes (odds ratio, 1.35; 95% confidence interval, 1.26-1.45) than in those without metabolic syndromes. Elevated blood pressure and a triglycerides abnormality were important predictors of restrictive ventilator defects. Sex-stratified subgroup analyses of the individual metabolic abnormalities indicated that men with abdominal obesity and women with dysglycemia were more likely to develop restrictive ventilatory defects. CONCLUSIONS Our study's evidence suggested that metabolic syndromes were important predictors of impaired pulmonary function and an increased risk of developing restrictive ventilatory defects, and its risk increased with increasing numbers of metabolic abnormalities.

Diabetol Metab Syndr 2023; 15:65. [PMID: 37005609 PMCID: PMC10067203 DOI: 10.1186/s13098-023-01042-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 03/24/2023] [Indexed: 04/04/2023] Open
Abstract
BACKGROUND/OBJECTIVE Metabolic syndrome (MS) is related to lung dysfunction. However, its impact according to insulin resistance (IR) remains unknown. Therefore, we evaluated whether the relation of MS with lung dysfunction differs by IR. SUBJECT/METHODS This cross-sectional study included 114,143 Korean adults (mean age, 39.6 years) with health examinations who were divided into three groups: metabolically healthy (MH), MS without IR, and MS with IR. MS was defined as presence of any MS component, including IR estimated by HOMA-IR ≥ 2.5. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for lung dysfunction were obtained in MS, MS without IR, and MS with IR groups compared with the MH (reference) group. RESULTS The prevalence of MS was 50.7%. The percent predicted forced expiratory volume in 1 s (FEV1%) and forced vital capacity (FVC%) showed statistically significant differences between MS with IR and MH and between MS with IR and MS without IR (all P < 0.001). However, those measures did not vary between MH and MS without IR (P = 1.000 and P = 0.711, respectively). Compared to MH, MS was not at risk for FEV1% < 80% (1.103 (0.993-1.224), P = 0.067) or FVC% < 80% (1.011 (0.901-1.136), P = 0.849). However, MS with IR was clearly associated with FEV1% < 80% (1.374 (1.205-1.566) and FVC% < 80% (1.428 (1.237-1.647) (all p < 0.001), though there was no evident association for MS without IR (FEV1%: 1.078 (0.975-1.192, P = 0.142) and FVC%: 1.000 (0.896-1.116, p = 0.998)). CONCLUSION The association of MS with lung function can be affected by IR. However, longitudinal follow-up studies are required to validate our findings.

High-Density Lipoprotein Cholesterol: A Component of the Metabolic Syndrome with a New Role in Lung Function. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6615595. [PMID: 34188689 PMCID: PMC8192195 DOI: 10.1155/2021/6615595] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 05/20/2021] [Indexed: 01/29/2023]
Abstract
Background A considerable uncertainty exists about the relationship between adult metabolic syndrome (MS) and obstructive lung disease (OLD), perhaps owing to systemic inflammation. Therefore, this study aimed to investigate the relationship between MS (with its components) and the patterns of lung function impairment. Methods The participants in this study were 3978 adults aged 30-78 years from the baseline cohort of the Ningxia Cohort Study. The participants underwent pulmonary function tests, questionnaire surveys, physical examinations, and analysis of blood specimens. Results No significant difference in the prevalence of OLD was observed between male (15.9%) and female (14.2%) participants. After adjusting for possible confounding factors (e.g., age and family income), impaired lung function was found to be related to some MS components, such as abdominal obesity, high blood pressure, and low levels of high-density lipoprotein cholesterol (HDL-C) (all P < 0.05). Conclusions As an important component of MS, abdominal obesity is related to impaired lung function. Surprisingly, this study found that increased HDL-C levels could accelerate the decline of lung function; it also suggests that in the presence of different metabolic health conditions, especially abdominal obesity and low levels of HDL-C, various metabolic indicators should be comprehensively considered to prevent the decline of lung function. This partly explains the increase in the incidence of two or more chronic diseases. Therefore, the prevention of chronic diseases should shift from single-disease prevention to a comprehensive consideration of multi-disease prevention in the future. Therefore, a more sensitive evaluation of the role of HDL-C in lung function is warranted.

Abstract
Purpose To identify associated factors of having at least one of the airflow limitation, chronic cough/phlegm, and currently treated respiratory diseases in health examinees, and to describe the characteristics of each subgroup classified by comorbidities. Subjects and Methods This was an observational cross-sectional survey carried out in multiple regions of Japan. Subjects aged 40 years older, undergoing comprehensive health examination, were recruited. Airflow limitation was defined as having forced expiratory volume in 1 s/forced vital capacity lower than 70%. Associated factors of having at least one of the airflow limitation, chronic cough/phlegm, and currently treated respiratory diseases were examined by logistic regression analysis. Subgroup classification by comorbidity patterns was conducted by hierarchical cluster analysis. Results In a total of 22,293 subjects, 1520 (6.8%) had at least one of the airflow limitation, chronic cough/phlegm, and currently treated respiratory diseases. With this objective variable, the following explanatory variables were significantly associated: older age, higher total score in the chronic obstructive pulmonary disease assessment test (CAT) and coexistence of lung cancer (common in ever-smokers and never-smokers), higher pack-years, lower body mass index, higher C-reactive protein, without coexistence of diabetes mellitus (specific in ever-smokers), male sex, coexistence of anxiety, and sleep disorder (specific in never-smokers). Among the 1520 subjects, 1512 subjects with smoking history data were classified by comorbidity patterns into subgroups of "no comorbidities," "mixed comorbidities," "inflammatory comorbidities," "overweight," "underweight," and "chronic kidney disease." "Inflammatory comorbidities" were specific in ever-smokers, and "underweight" was specific in never-smokers. Conclusion Several factors were identified as associated factors of having at least one of airflow limitation, chronic cough/phlegm, and currently treated respiratory diseases and they were different between ever-smokers and never-smokers. Different comorbidity patterns were observed by smoking history. These findings could provide information to assist the management of subjects with COPD or at risk for COPD in the general population.

Abstract
BACKGROUND AND AIMS Metabolic syndrome (MetS) has a significant association with airflow obstruction and physical inactivity, which are the relevant extra-pulmonary markers of chronic obstructive respiratory disease (COPD). This study aimed to estimate the prevalence of MetS and its correlation with comorbidities and health related quality of life (HRQoL) in South Indian patients with COPD. METHODS A cross-sectional study was conducted among the 76 COPD patients. Pulmonary function test (PFT) and parameters for MetS such as waist circumference, blood pressure, fasting blood glucose, triglycerides (TGs) and high density lipoprotein cholesterol (HDL-C) levels of COPD patients were measured. HRQoL was calculated using Saint George Respiratory Questionnaire (SGRQ). RESULTS 54% of COPD patients were presented with MetS especially in stage II and III. TGs and HDL-C were significantly associated with the severity of COPD (p < 0.05), while waist circumference, TGs and HDL-C were significantly (p < 0.05) correlated with PFT. Symptom, activity, impact and total scores of SGRQ was increased statistically (p < 0.05) in COPD patients with MetS than without MetS. CONCLUSION According to our findings, screening the grade II and III COPD patients for the presence of MetS is a reasonable option. The results of this study should be confirmed with a larger sample of population.

Abstract
Background: Evidence suggests that metabolic syndrome (MetS) is highly prevalent in patients with obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD). However, data on the prevalence of MetS in patients having both OSAS and COPD, or overlap syndrome (OS), are scarce. The aim of this study was to evaluate the prevalence and identify predictors of MetS in patients with OS. Methods: MetS was evaluated in consecutive patients who were diagnosed with OS by polysomnography and pulmonary function testing. Results: A total of 163 subjects (138 males and 25 females) were included. MetS was present in 38% of OS patients. Patients were divided into group A (OS without MetS group: 101 patients) and group B (OS with MetS group: 62 patients). Groups were similar in terms of pulmonary function and sleep parameters. In group B, abdominal obesity was the most prevalent component of MetS (100%), followed by hypertension (82.3%), hypertriglyceridemia (72.6%), and hyperglycemia (51.6%). Age (P = 0.009) and body mass index (P = 0.029) were independent predictors of MetS in patients with OS. Conclusions: An increased prevalence of MetS was observed in a group of patients with OS. Early identification and treatment of MetS may play a significant role in prevention of complications related to OS.

Abstract
AIMS We compared strengths of associations conferred by the metabolic syndrome (MetS) and its components across four chronic disease categories (cancer, cardiovascular diseases [CVDs], chronic kidney disease [CKD], and chronic obstructive pulmonary disease [COPD]) in a community-dwelling high-risk population. METHODS This is a cross-sectional analysis of Israeli adults insured in a single health maintenance organization during 2010 to 2013 and having greater than or equal to two MetS components (hypertension, dysglycemia, low high-density lipoprotein level, high plasma triglyceride level, and obesity). Data regarding MetS components, chronic disease prevalence, and sociodemographic variables were retrieved from electronic health records and disease registries. RESULTS Among 347 244 eligible members, 54.2% had MetS. MetS was negatively associated with cancer, (prevalence ratio [PR] = 0.86; 95% confidence interval, 0.79-0.93) and positively associated with CKD (PR = 1.07, [1.01-1.13]). Some MetS components conferred different associations across the chronic diseases: a high triglyceride level was positively associated with cancer (PR = 1.15, 1.12-1.18) and CKD (PR = 1.37, 1.32-1.41) but negatively associated with CVD (PR = 0.88, 0.86-0.90) and COPD (PR = 0.93, 0.88-0.98). In the presence of MetS, those with dysglycemia had higher cancer prevalence than those with normoglycemia (PR-interaction MetS*dysglycemia on cancer = 1.14, 1.06-1.22). Likewise, in the presence of MetS, men were more likely than women to present with CVD (PR-interaction MetS*sex on CVD = 1.12, [1.05-1.20]). CONCLUSIONS Prevalences of the MetS and MetS components distribute unequally across four chronic diseases. MetS including dysglycemia may warrant screening for cancer, and MetS in males may indicate the presence of CVD. Longitudinal studies may reveal if MetS is associated with different risks or merely indicates better prognosis once having a chronic illness.

Abstract
A preferred reporting items for systematic reviews and meta-analyses-compliant meta-analysis was conducted to test the association of metabolic syndrome and its components with the risk of chronic obstructive pulmonary disease (COPD) based on observational studies. Literature retrieval, article selection and data extraction were done by two researchers independently. Total 16 articles (20 independent studies) were analyzed with 3915 COPD patients and 25,790 control participants. Overall analysis indicated that metabolic syndrome was significantly associated with 1.53-fold (95% confidence interval [CI]: 1.23–1.9, P<0.001) increased risk of COPD, with moderate heterogeneity (I2 = 74.3%). Of four metabolic components, hypertension was significantly associated with 1.55-fold (95% CI: 1.14–2.11, P=0.005) increased risk, and averaged levels of systolic blood pressure (weighted mean difference [WMD] = 3.626 mmHg, 95% CI: 1.537–5.714, P<0.001) and glucose (WMD = 2.976 mmol/l, 95% CI: 0.141–5.812; P=0.04) were significantly higher in COPD patients than in control participants, yet that of body mass index (WMD = −1.463 kg/m2, 95% CI: −2.716 to −0.211, P=0.022) were significantly lower. Gender, race, source of control participants, matched status and sample size were identified as accountable factors for significant heterogeneity. Altogether, the presence of metabolic syndrome, especially its component hypertension, was associated with significantly increased risk of COPD.

Abstract
BACKGROUND Diabetes has been reported as a comorbidity of chronic obstructive pulmonary disease (COPD) in Western countries, but it has not been demonstrated in epidemiological reports in Japan. The purpose of this study was to clarify whether the relationship between airflow obstruction and diabetes can be confirmed in a Japanese general population. METHODS From 2004 to 2006, blood sampling and pulmonary function tests were performed on 3045 people over the age of 40 years in annual health check-ups held in Takahata, Yamagata Prefecture, Japan. Pulmonary function was re-evaluated in 2009 and 2011. RESULTS The prevalence of diabetes did not differ between subjects with and without airflow obstruction. Furthermore, although body mass index decreased, no increase in the prevalence of diabetes was observed with the progression of airflow obstruction. The annual changes in forced expiration volume in 1s (FEV1) did not differ depending on the presence or absence of diabetes in the study population. CONCLUSION There was no difference in the prevalence of diabetes between subjects with airflow obstruction and those without. As patients with COPD in Japan are thinner than in the West, diabetes may not be a common comorbidity in Japanese patients with COPD.

Abstract
OBJECTIVES The present study aimed to investigate the relationship between airflow limitation (AL) severity and comorbidities in comprehensive health examination. METHODS This cross-sectional study included 6661 men and 6044 women aged 40-89 who underwent a lung function test during medical checkups. AL was defined as forced expiratory volume in 1 s/forced vital capacity of < 0.7. Logistic regression analysis was used to assess the association between AL severity and the presence of comorbidities. RESULTS When compared with the normal lung function group, subjects with AL had a higher prevalence of lung cancer (odd ratio (OR) 9.88, 95% confidence interval (CI) 3.88-25.14) in men, hypertension (OR 1.63, 95% CI 1.26-2.10) in women, diabetes and hyperglycemia (OR 1.23, 95% CI 1.02-1.49 in men, OR 1.61, 95% CI 1.18-2.20 in women) in men and women after adjusting for potential confounders. In men, lung cancer and MetS (the Joint Interim Statement: JIS) were significantly associated with moderate-to-very severe AL after adjustment. In women, hypertension, diabetes and hyperglycemia, MetS (JIS), and MetS (the Japanese Committee of the Criteria for MetS: JCCMS) were significantly associated with mild AL after adjustment. Hypertension was significantly associated with moderate-to-very severe AL after adjustment in women. CONCLUSIONS Significant relationships were found between AL severity and the presence of comorbid lung cancer in men, hypertension in women, diabetes and hyperglycemia, and MetS in men and women. Knowledge of comorbidities associated with AL should be widely publicized to raise the awareness of chronic obstructive pulmonary disease (COPD).

Abstract
BACKGROUND The aim of this study was to reveal the association between airflow limitation (AL) severity and reduction with work productivity as well as use of sick leave among Japanese workers. METHODS This cross-sectional study included 1,378 workers who underwent a lung function test during a health checkup at the Japanese Red Cross Kumamoto Health Care Center. AL was defined as forced expiratory volume in 1 second/forced vital capacity of <0.7. Workers completed a questionnaire on productivity loss at work and sick leave. The quality and quantity of productivity loss at work were measured on a ten-point scale indicating how much work was actually performed on the previous workday. Participants were asked how many days in the past 12 months they were unable to work because of health problems. Logistic regression analysis was used to assess the associations between AL severity and the quality and quantity of productivity loss at work as well as use of sick leave. RESULTS Compared with workers without AL, workers with moderate-to-severe AL showed a significant productivity loss (quality: odds ratio [OR] =2.04, 95% confidence interval [CI]: 1.12-3.71, P=0.02 and quantity: OR =2.19, 95% CI: 1.20-4.00, P=0.011) and use of sick leave (OR =2.69, 95% CI: 1.33-5.44, P=0.006) after adjusting for sex, age, body mass index, smoking status, hypertension, hyperglycemia, dyslipidemia, sleep duration, work hours per day, and workplace smoking environment. CONCLUSION AL severity was significantly associated with work productivity loss and use of sick leave. Our findings suggested that early intervention in the subjects with AL at the workforce might be beneficial for promoting work ability.

Abstract
Introduction. The metabolic syndrome (MS) affects 21-53% of patients with chronic obstructive pulmonary disease (COPD) with a higher prevalence in the early stages of COPD, with results being highly variable between studies. MS may also affect natural course of COPD-number of exacerbations, quality of life and lung function. Aim. To examine the prevalence of MS and its correlation with comorbidities and COPD characteristics in patients with COPD admitted for exacerbation. Material and methods. 152 patients with COPD admitted for exacerbation were studied for presence of MS. All of them were also assessed for vitamin D status and diabetes mellitus type 2 (DM). Data were gathered for smoking status and exacerbations during the last year. All patients completed CAT (COPD assessment test) and mMRC (Modified Medical Research Council Dyspnea scale) questionnaires and underwent spirometry. Duration of current hospital stay was recorded. Results. 25% of patients have MS. 23.1% of the male and 29.5% of the female patients have MS (p > 0.05). The prevalence of MS in this study is significantly lower when compared to a national representative study (44.6% in subjects over 45 years). 69.1% of all patients and 97.4% from MS patients have arterial hypertension. The presence of MS is associated with significantly worse cough and sleep (1st and 7th CAT questions; p = 0.002 and p = 0.001 respectively) and higher total CAT score (p = 0.017). Average BMI is 27.31. None of the patients have MS and BMI <25. There is a correlation between the presence of MS and DM (p = 0.008) and with the number of exacerbations in the last year (p = 0.015). There is no correlation between the presence of MS and the pulmonary function. Conclusion. This study among hospitalized COPD patients finds comparable but relatively low prevalence of MS (25%) compared to previously published data (21-53%) and lower prevalence compared to general population (44.6%). MS may impact quality of life and the number of exacerbations of COPD. Having in mind that MS is more common in the early stages and decreases with COPD progression, the COPD patients admitted for exacerbation may be considered as having advanced COPD.

Abstract
The metabolic syndrome is found to be more frequent in chronic obstructive pulmonary disease (COPD). The presence of inflammatory markers in circulation, sputum, and broncho-alveolar fluid suggest systemic inflammation is one of the potential mechanisms responsible for both COPD and metabolic syndrome. Physical inactivity, skeletal muscle dysfunction, hypogonadism, and steroid use are also important causes of the metabolic syndrome in COPD. Obesity and insulin resistance is found to be more common in mild to moderate stages (I and II) of COPD. Patients with COPD and the metabolic syndrome have increase risk of morbidity and mortality due to cardiovascular disease. This review describes in details the various components of metabolic syndrome and its impact on long outcomes in COPD patients.

Abstract
Chronic obstructive pulmonary disease (COPD) and the metabolic syndrome (MetS) are considered public health challenges of the 21st century. The coexistence of MetS in COPD patients and any clinical differences between COPD patients with and without MetS have not been extensively studied. We aimed to describe the clinical characteristics of patients with MetS and COPD. An observational, multicenter study of 375 patients hospitalized for a COPD exacerbation with spirometric confirmation was performed. We measured the components of the MetS and collected comorbidity information using the Charlson index and other conditions. Dyspnea, use of steroids, exacerbations, and hospitalizations were also investigated. The overall prevalence of MetS in COPD patients was 42.9 %, was more frequent in women (59.5 %) than men (40.8 %), p = 0.02, but with no differences in age and smoking history. COPD patients with MetS had greater % predicted FEV1, more dyspnea, and more comorbidity and used more inhaled steroids (all p < 0.05). Diabetes, osteoporosis, coronary artery disease, and heart failure were more frequent in patients with MetS. They had been hospitalized more frequently for any cause but not for COPD. In multivariate analysis, the presence of MetS was independently associated with greater FEV1, inhaled steroids use, osteoporosis, diabetes, and heart failure. MetS is a frequent condition in COPD patients, and it is associated with greater FEV1, more dyspnea, and more comorbidities.

Abstract
OBJECTIVES There is some evidence that chronic obstructive pulmonary disease and chronic kidney disease (CKD) may be related, perhaps through systemic inflammation, which is common to both. However, this relationship has not yet been clearly demonstrated. The aim of this study was to investigate the association between airflow obstruction, CKD, and C-reactive protein (CRP) levels in Japanese men. METHODS The study included 11,587 men, aged 40-88 years, who underwent a health check-up. Airflow obstruction was defined as a forced expiratory volume in 1 s/forced vital capacity of <70%, and its severity was based on the Global Initiative for Chronic Obstructive Lung Disease guidelines (GOLD). CKD was defined as an estimated glomerular filtration rate of <60 mL/min/1.73 m(2). RESULTS Airflow obstruction was present in 7.9% of the participants, and 10.6% of the participants had CKD. The average CRP levels were 0.11 ± 0.36, 0.13 ± 0.41, and 0.18 ± 0.41 mg/L for subjects with normal lung function, GOLD stage I, and GOLD stage II-IV, respectively. With regard to CKD, the average CRP levels were 0.11 ± 0.32 and 0.18 ± 0.6 mg/L for subjects without and with CKD, respectively. Analysis of covariance showed no significant differences between the CRP level and lung function status or CKD after age was adjusted for. Logistic regression analysis showed no association among subjects with the three different lung function statuses after age, body mass index, hypertension, diabetes, hyper-low-density-lipoprotein-cholesterolemia, smoking, physical activity, and alcohol intake were controlled for. CONCLUSIONS Based on the results of this study, we conclude that there is no interrelationship between CRP level, airflow obstruction, and CKD.

Abstract
OBJECTIVES Chronic kidney disease (CKD) is a major public health problem. Epidemiological studies of the relationship between alcohol intake and CKD are scarce in Japan. This cross-sectional study aims to investigate the relationship between frequency of drinking alcohol and CKD in Japanese men. METHODS The subjects were 9,196 men (mean ± standard deviation age, 57.9 ± 5.1 years) who underwent a health check-up. CKD was defined as estimated glomerular filtration rate <60 mL/min/1.73 m(2). Frequency of alcohol drinking was obtained from questionnaire and divided into five categories: nondrinkers, once or twice a week, three or four times a week, five or six times a week, and everyday drinkers. RESULTS Multivariable-adjusted [age, body mass index, hypertension, diabetes, hyper-low-density lipoprotein (LDL) cholesterolemia, smoking, and physical activity] odds ratios and 95% confidence intervals (CIs) were calculated using logistic regression analysis. Compared with the results for the nondrinkers, the multivariable-adjusted odds ratios of CKD were as follows: 0.76 (95% CI 0.60-0.95) for 1-2 drinks per week, 0.74 (95% CI 0.59-0.93) for 3-4 drinks per week, 0.79 (95% CI 0.64-0.97) for 5-6 drinks per week, and 0.60 (95% CI 0.51-0.71) for everyday drinkers. There was a significant inverse trend across increasing frequency of drinking alcohol (p = 0.001 for trend). CONCLUSIONS An inverse association was found between frequency of drinking alcohol and CKD in apparently healthy men.
