Weight change and the risk of hip fractures in patients with type 2 diabetes: a nationwide cohort study.

Both weight gain and weight loss in type 2 diabetic population were associated with increased risk of hip fracture, while maintaining weight lowered the risk of hip fracture. Regarding the risk of hip fracture, we can propose active monitoring to maintain the weight of type 2 diabetes patients. INTRODUCTION: In type 2 diabetes, patients are often asked to control their weight in order to reduce their diabetic morbidity. The American Diabetes Association recommends that diabetic patients conduct high-intensity interventions for regulating diet, physical activity, and behavior to reduce weight, followed by long-term comprehensive weight maintenance programs. Although such weight control attempts are required in diabetic patients, there are few studies on the effect of weight change on hip fracture in this population. We aim to investigate the association between body weight change and the incidence of hip fracture in subjects with type 2 diabetes using large-scale, nationwide cohort data on the Korean population. MATERIALS AND METHODS: A total of 1,447,579 subjects (894,204 men and 553,375 women) > 40 years of age, who were diagnosed with type 2 diabetes, were enrolled in this study. Weight change within 2 years was divided into five categories: from weight loss ≥ 10% to weight gain ≥ 10%. The hazard ratios (HRs) and 95% confidence intervals for the incidence of hip fracture were analyzed, compared with the reference of the stable weight group (weight change < 5%). RESULTS: Among 5 weight change groups, more than 10% weight loss showed the highest HR (HR, 1.605; 95% CI, 1.493 to 1.725), followed by more than 10% weight gain (HR, 1.457; 95% CI, 1.318 to 1.612). The effect of weight change on hip fracture risk was greater in males than in females, and those under 65 years of age were greater than those over 65 years of age. Baseline BMI did not play a role of weight change affecting the risk of hip fracture. The HR for hip fracture of subjects with regular exercise was lower than those without regular exercise. CONCLUSIONS: In the type 2 diabetes population, both weight gain and weight loss were significantly associated with a higher risk of hip fracture, whereas maintaining body weight reduced the risk of hip fracture the most.

Effect of follow-up raloxifene therapy after denosumab discontinuation in postmenopausal women.

Follow-up raloxifene therapy after denosumab discontinuation resulted in a decrease in bone mass to the pre-denosumab levels and a rebound increase of bone turnover markers. The decrease in lumbar bone mineral density was particularly evident when the body mass index was low, there were previous vertebral fractures, or lumbar bone mineral density before denosumab administration was low. INTRODUCTION: Selective estrogen receptor modulators may be an alternative to bisphosphonates for treating rebound resorption after discontinuing denosumab. This study aimed to investigate the effects of follow-up raloxifene therapy after denosumab discontinuation in postmenopausal women. METHODS: This retrospective observational study included 61 patients who received 12-month follow-up raloxifene therapy after denosumab discontinuation. The primary endpoint was the bone mineral density change. The secondary endpoints were the changes in bone turnover markers and the incidence of new vertebral fractures. RESULTS: Raloxifene administration for 12 months after denosumab discontinuation resulted in a significantly lower bone mineral density at all sites compared to the level at 6 months after the last denosumab treatment (lumbar spine, - 5.48%; femoral neck, - 2.95%; total hip, - 3.52%; all, p < 0.001). The decrease in lumbar bone mineral density was particularly evident when the body mass index was low, there were previous vertebral fractures, or lumbar bone mineral density before denosumab administration was low. Marked increases in the bone turnover markers from baseline were noted after switching to raloxifene. However, no new vertebral fractures occurred during raloxifene treatment. CONCLUSIONS: Follow-up raloxifene therapy after denosumab discontinuation resulted in a decrease in bone mass to the pre-denosumab levels and a rebound increase of bone turnover markers. Therefore, raloxifene administered sequentially after denosumab discontinuation was not effective in preventing rebound phenomenon.

Comparison of fracture risk between type 1 and type 2 diabetes: a comprehensive real-world data.

Population-based cohort study of 6,548,784 Korean subjects demonstrates that the risk of fracture was higher in patients with diabetes than in nondiabetic subjects. Furthermore, patients with type 1 diabetes were associated with a higher risk of fracture than patients with type 2 diabetes for all measurement sites. INTRODUCTION: Diabetes mellitus is associated with increased fracture risk. Although the pathophysiologic effect on bone metabolism differs according to the type of diabetes, a higher risk of fracture in patients with diabetes than in nondiabetic patients has been consistently demonstrated. Considering the ever-increasing number of patients with diabetes, we aimed to provide updated information on whether this phenomenon remains valid in real-world settings by using large-scale population datasets. METHODS: We conducted a retrospective longitudinal study using data from the Korean National Health Insurance Service dataset of preventive health check-ups between January 2009 and December 2016. The hazard ratios were calculated for any fracture, vertebral fracture, and hip fracture and were analyzed according to the presence and type of diabetes. Among 10,585,818 subjects, 6,548,784 were eligible for the analysis (2418 patients with type 1 diabetes mellitus [T1DM] and 506,208 patients with type 2 diabetes mellitus [T2DM]). RESULTS: The mean follow-up duration (in years) was 7.0 ± 1.3 for subjects without diabetes, 6.4 ± 2.0 for those with T1DM, and 6.7 ± 1.7 for T2DM. Patients with T1DM had a higher incidence rate for all types of fractures per 1000 person-years. The fully adjusted hazard ratios (HRs) for any fracture, vertebral fracture, and hip fracture were higher in T1DM than in T2DM (1.37 [95% confidence interval (CI): 1.23-1.52] for any fracture, 1.33 [95% CI: 1.09-1.63] for vertebral fracture, and 1.99 [95% CI: 1.56-2.53] for hip fracture). CONCLUSIONS: In this large-scale population analysis, diabetes was associated with a higher risk of all types of fractures. Patients with T1DM had a higher risk of fracture than those with T2DM for all measurement sites, and hip fractures had the highest risk. Therefore, fracture prevention training for patients with diabetes is advisable.

White matter hyperintensities and recurrent stroke risk in patients with stroke with small-vessel disease.

BACKGROUND AND PURPOSE: White matter hyperintensities (WMH) are a predictor of stroke among elderly individuals. This study aimed to evaluate the association between WMH severity and the risk of recurrent vascular events among Asian patients with ischaemic stroke with small-vessel disease (SVD) including micro/macrobleeds and lacunes. METHODS: Data from participants (n = 1454) in the PICASSO (PreventIon of CArdiovascular Events in iSchemic Stroke Patients with High Risk of Cerebral HemOrrhage) trial were reviewed. The severity of WMH in baseline brain magnetic resonance imaging scans was assessed using the Fazekas scale. The association between WMH severity and stroke (ischaemic or hemorrhagic) and major vascular events (MVEs) (a composite of stroke/myocardial infarction/vascular death) was assessed. RESULTS: Study patients had a significant burden of SVD: Fazekas score 0 (n = 2), 1 (n = 426), 2 (n = 650) and 3 (n = 376) [median Fazekas score 2 (mean follow-up, 1.9 ± 1.3 years)]. The stroke incidence rate per 100 personyears was 2.6 in the Fazekas 0-1 group, 3.6 in the Fazekas 2 group and 7.0 in the Fazekas 3 group, and the rates for MVEs were 3.3, 4.3 and 7.6, respectively. Compared with the Fazekas 0-1 group, the Fazekas 3 group was associated with a higher risk of stroke [adjusted hazard ratio (HR), 2.15; 95% confidence interval (CI), 1.19-3.88; P = 0.011], ischaemic stroke (adjusted HR, 2.11; 95% CI, 1.07-4.15; P = 0.031), hemorrhagic stroke (adjusted HR, 3.72; 95% CI, 1.09-12.70; P = 0.036) and MVEs (adjusted HR, 2.09; 95% CI, 1.20-3.66; P = 0.010). CONCLUSION: Advanced WMH in Asian patients with ischaemic stroke with SVD burden was associated with an increased risk of recurrent vascular events. It may exert an effect as a prognostic indicator in high risk of recurrent vascular events.

Prevalence and comorbidities associated with hidradenitis suppurativa in Korea: a nationwide population-based study.

BACKGROUND: The prevalence of hidradenitis suppurativa (HS) in Asia is unknown. The associations between HS and other autoimmune disorders have rarely been reported. OBJECTIVE: We sought to determine the prevalence of and diseases associated with HS using the National Health Insurance (NHI) database. METHODS: We examined Korean NHI claim database data from 2007 to 2016. We enrolled all patients with HS and age- and sex-matched control subjects without HS. We estimated the period prevalence of HS and associated comorbidities in Korea. RESULTS: We identified 28 516 patients with HS (61.3% males and 38.7% females). The period prevalence rate was 0.06%, 55.8 patients (95% confidence interval 55.1-56.4) per 100 000 persons, and the female-to-male ratio was 1 : 1.6. HS patients were at significantly increased risk of rheumatoid arthritis, ankylosing spondylitis, type 1 diabetes, ulcerative colitis, type 2 diabetes, hypertension, hyperlipidaemia, acne conglobata, pilonidal cysts, psoriasis, pyoderma gangrenosum, alopecia areata and vitiligo. CONCLUSION: The overall prevalence of HS in Korea was lower than that in Western populations, and male patients predominated.

Serum preadipocyte factor 1 concentrations and risk of developing diabetes: a nested case-control study.

AIM: To determine whether preadipocyte factor 1 could be a predictive marker for the development of diabetes in people without diabetes at baseline. METHODS: We conducted a population-based, nested case-control study of individuals who progressed to diabetes (n = 43) or prediabetes (n = 345) and control participants matched on age, sex and fasting plasma glucose concentration, who maintained normal glucose tolerance (n = 389) during a 4-year follow-up using data from the Chungju Metabolic disease Cohort Study. Circulating levels of preadipocyte factor 1 were measured using an enzyme-linked immunosorbent assay. RESULTS: Baseline serum preadipocyte factor 1 levels showed a stepwise decrease across the glucose tolerance status groups at follow-up (normal glucose tolerance: 10.02 ± 3.02 ng/ml; prediabetes: 9.48 ± 3.35 ng/ml; diabetes: 8.66 ± 3.29 ng/ml; P for trend, 0.0151). Individuals whose fasting plasma glucose level had increased or whose homeostasis model assessment of ß-cell function had decreased at follow-up showed significantly lower levels of preadipocyte factor 1 compared with their control group counterparts. After adjusting for age, BMI, fasting plasma glucose, serum insulin levels, systolic blood pressure and triglycerides, the incidence of diabetes was nearly threefold higher in the lowest vs. the upper three quartiles of circulating preadipocyte factor 1 (relative risk 2.794; 95% CI 1.188-6.571; P = 0.0185). Notably, these findings were significant in women but not in men. CONCLUSIONS: Levels of circulating preadipocyte factor 1 may be a useful biomarker for identifying women at high risk of developing diabetes.

Preventive effect of fermented Maillard reaction products from milk proteins in cardiovascular health.

The aim of this study was to determine the dual effect of Maillard reaction and fermentation on the preventive cardiovascular effects of milk proteins. Maillard reaction products (MRP) were prepared from the reaction between milk proteins, such as whey protein concentrates (WPC) and sodium caseinate (SC), and lactose. The hydrolysates of MRP were obtained from fermentation by lactic acid bacteria (LAB; i.e., Lactobacillus gasseri H10, L. gasseri H11, Lactobacillus fermentum H4, and L. fermentum H9, where human-isolated strains were designated H1 to H15), which had excellent proteolytic and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities (>20%). The antioxidant activity of MRP was greater than that of intact proteins in assays of the reaction with 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt and trivalent ferric ions; moreover, the effect of MRP was synergistically improved by fermentation. The Maillard reaction dramatically increased the level of antithrombotic activity and 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) inhibitory effect of milk proteins, but did not change the level of activity for micellar cholesterol solubility. Furthermore, specific biological properties were enhanced by fermentation. Lactobacillus gasseri H11 demonstrated the greatest activity for thrombin and HMGR inhibition in Maillard-reacted WPC, by 42 and 33%, respectively, whereas hydrolysates of Maillard-reacted SC fermented by L. fermentum H9 demonstrated the highest reduction rate for micellar cholesterol solubility, at 52%. In addition, the small compounds that were likely released by fermentation of MRP were identified by size-exclusion chromatography. Therefore, MRP and hydrolysates of fermented MRP could be used to reduce cardiovascular risks.

Healthcare use and prescription patterns associated with adult asthma in Korea: analysis of the NHI claims database.

BACKGROUND: National Health Insurance (NHI) claim records could provide valuable data for epidemiological studies of asthma in Korea. The aim of this study is to estimate the prevalence of adult asthma and to investigate asthma-related healthcare use and prescription patterns in Korea over 5 years. METHODS: National Health Insurance claim records from January 1, 2006 to December 31, 2010 were analyzed in a retrospective, population-based study. Outcome measures included asthma prevalence, healthcare use, and prescription patterns over time, by type of hospital, and by medical specialty. Additionally, we assessed differences in healthcare use between newly diagnosed and previously diagnosed patients in 2009. RESULTS: Over 5 years, the prevalence of asthma among Korean adults increased from 4944 to 5707 cases per 100,000 population (from 3760 to 4445 in men and from 6108 to 6951 in women). Asthma-related outpatient visits decreased from 4.82 ± 8.02 to 3.44 ± 5.50. Approximately 3% of all patients were hospitalized and 2.4% received asthma-related emergency treatment each year. Pulmonary function tests were performed in 10-11% of patients an average of 1.3 times per year. Newly diagnosed patients experienced fewer asthma-related hospitalizations (1.78% vs 4.35%) and emergency department visits (0.80% vs 2.11%) than the previously diagnosed group. Prescriptions of inhaled corticosteroids-based inhalers were maintained with about 20% of average of all types of hospitals. CONCLUSIONS: The prevalence of asthma in Korea has increased over a recent 5-year period, and asthma is still suboptimally controlled. Public health strategies are needed to improve the management of asthma in adults.

Validation of the cephalosporin intradermal skin test for predicting immediate hypersensitivity: a prospective study with drug challenge.

BACKGROUND: Cephalosporin is a major offending agent in terms of drug hypersensitivity along with penicillin. Cephalosporin intradermal skin tests (IDTs) have been widely used; however, their validity for predicting immediate hypersensitivity has not been studied. This study aimed to determine the predictive value of cephalosporin intradermal skin testing before administration of the drug. METHODS: We prospectively conducted IDTs with four cephalosporins, one each of selected first-, second-, third-, or fourth-generation cephalosporins: ceftezol; cefotetan or cefamandole; ceftriaxone or cefotaxime; and flomoxef, respectively, as well as with penicillin G. After the skin test, whatever the result, one of the tested cephalosporins was administered intravenously and the patient was carefully observed. RESULTS: We recruited 1421 patients who required preoperative cephalosporins. Seventy-four patients (74/1421, 5.2%) were positive to at least one cephalosporin. However, none of responders had immediate hypersensitivity reactions after a challenge dose of the same or different cephalosporin, which were positive in the skin test. Four patients who suffered generalized urticaria and itching after challenge gave negative skin tests for the corresponding drug. The IDT for cephalosporin had a sensitivity of 0%, a specificity of 97.5%, a negative predictive value of 99.7%, and a positive predictive value (PPV) of 0%, when challenged with the same drugs that were positive in the skin test. CONCLUSION: Routine skin testing with a cephalosporin before its administration is not useful for predicting immediate hypersensitivity because of the extremely low sensitivity and PPV of the skin test (CRIS registration no. KCT0000455).

Higher levels of small dense low-density lipoprotein (LDL) are associated with cardiac autonomic neuropathy in patients with type 2 diabetes.

AIM: To investigate the relationship between small dense LDL cholesterol and cardiac autonomic neuropathy among patients with Type 2 diabetes. METHODS: A total of 175 patients who had not taken lipid-lowering agents previously were enrolled consecutively in this study. Small dense LDL cholesterol level was measured using polyacrylamide tube gel electrophoresis, which fractionates LDL cholesterol into seven components according to particle size and charge. We analysed the mean LDL cholesterol particle size and the proportion of small dense LDL cholesterol. RESULTS: The mean (± sd) patient age was 56 (± 14) years, the mean (± sd) duration of diabetes was 10.3 (± 8.3) years, the mean (± sd) proportion of small dense LDL cholesterol was 21.3 (± 17.6)% and the mean (± sd) LDL cholesterol size was 26.33 (± 0.8) nm. Men with cardiac autonomic neuropathy had a longer duration of diabetes compared with those without cardiac autonomic neuropathy. Women with cardiac autonomic neuropathy had a larger waist circumference, higher plasma triglyceride levels, smaller mean (± sd) LDL cholesterol size [26.8 (± 4.3) nm vs 26.4 (± 6.9) nm; P < 0.01] and larger mean (± sd) proportion of small dense LDL cholesterol [10.1 (± 9.9)% vs 19.1 (± 16.8)%; P < 0.01] compared with those without cardiac autonomic neuropathy. After adjusting for other confounding risk factors, the triglyceride/ HDL cholesterol ratio (odds ratio = 1.698, 95% CI: 1.07-2.69; P = 0.025) and mean LDL cholesterol size (odds ratio = 0.873, 95% CI: 0.77-0.99; P = 0.038) remained as independent risk factors for cardiac autonomic neuropathy in women. CONCLUSIONS: A more atherogenic lipid profile such as the triglyceride: HDL cholesterol ratio and a smaller mean LDL cholesterol particle size were related to the prevalence of cardiac autonomic neuropathy in women with Type 2 diabetes.

Prevalence and clinical characteristics of diabetic peripheral neuropathy in hospital patients with Type 2 diabetes in Korea.

AIMS: Diabetic peripheral neuropathy is a common complication of diabetes. This cross-sectional study investigated the prevalence and clinical characteristics of this neuropathy in patients with Type 2 diabetic mellitus treated at hospitals in Korea. METHODS: Questionnaires and medical records were used to collect data on 4000 patients with Type 2 diabetes from the diabetes clinics of 40 hospitals throughout Korea. Diabetic peripheral neuropathy was diagnosed based on a review of medical records or using the Michigan Neuropathy Screening Instrument score and monofilament test. RESULTS: The prevalence of neuropathy was 33.5% (n = 1338). Multivariate analysis revealed that age, female sex, diabetes duration, lower glycated haemoglobin, treatment with oral hypoglycaemic agents or insulin, presence of retinopathy, history of cerebrovascular or peripheral arterial disease, presence of hypertension or dyslipidaemia, and history of foot ulcer were independently associated with diabetic peripheral neuropathy. Of the patients with neuropathy, 69.8% were treated for the condition and only 12.6% were aware of their neuropathy. CONCLUSION: There was a high prevalence of peripheral neuropathy in patients with Type 2 diabetes in Korea and those patients were far more likely to have complications or co-morbidities. The proper management of diabetic peripheral neuropathy deserves attention from clinicians to ensure better management of diabetes in Korea.

The Dietary Effects of Fermented Chlorella vulgaris (CBT(®)) on Production Performance, Liver Lipids and Intestinal Microflora in Laying Hens.

Fermented Chlorella vulgaris CBT(®) was evaluated for its effects on egg production, egg quality, liver lipids and intestinal microflora in laying hens. One hundred and eight Hy-line Brown layers (n = 108), 80 wk of age, were fed a basal diet supplemented with CBT(®) at the level of 0, 1,000 or 2,000 mg/kg, respectively for 42 d. Egg production was measured daily and egg quality was measured every two weeks. Five eggs from each replicate were collected randomly to determine egg quality. Egg production increased linearly with increasing levels of CBT(®) supplementation (p<0.05), although there was no significant effect of treatment on feed intake. Egg yolk color (p<0.001) and Haugh unit (p<0.01) improved linearly with increasing dietary CBT(®). Hepatic triacylglycerol level was linearly decreased with increasing dietary CBT(®) (p<0.05). The supplemental CBT(®) resulted in linear (p<0.001) and quadratic (p<0.01) response in population of cecal lactic acid bacteria. In conclusion, fermented Chlorella vulgaris supplemented to laying hen diets improved egg production, egg yolk color, Haugh unit and positively affected the contents of hepatic triacylglycerol and the profiles of cecal microflora.

Clonorchis sinensis infection is positively associated with atopy in endemic area.

BACKGROUND: Epidemiologic studies have suggested that helminth infections play a protective role against allergy; this inverse association, however, has not been consistent. Clonorchis sinensis, the liver fluke of human, is prevalent in the Far East. The association between C. sinensis infection and allergy has not yet been reported. OBJECTIVE: We evaluated the association between clonorchiasis and atopy or allergic diseases in adults in endemic areas of clonorchiasis. METHODS: A total of 1116 subjects (males 419, females 697; age range, 30-86; mean age=61 years) were recruited from two endemic areas of C. sinensis in Korea. Clonorchiasis was confirmed by stool examination. Allergic symptoms were evaluated with a modified ISAAC questionnaire, and atopy was defined by skin prick test for common inhalant allergens. Total serum IgE and C. sinensis-specific IgE level was measured by ELISA and methacholine bronchial provocation test was performed to evaluate airway hyperresponsiveness (AHR). RESULTS: Clonorchiasis was positively associated with atopy [odds ratio (OR), 1.856; 95% confidence interval (CI), 1.199-2.873] and high levels of total serum IgE (OR, 1.455; 95% CI, 1.050-2.016). Higher association with clonorchiasis was shown in subjects who showed both atopy and high total serum IgE levels (OR, 2.540; 95% CI, 1.448-4.455). Clonorchiasis had no association with wheezing, AHR, asthma or allergic rhinitis. CONCLUSION AND CLINICAL RELEVANCE: Clonorchiasis was positively associated with atopy in adults in endemic area.

Comparison of the efficacy and safety of tramadol/acetaminophen combination therapy and gabapentin in the treatment of painful diabetic neuropathy.

AIMS: This study compared the efficacy and safety of tramadol/acetaminophen (T/A) and gabapentin in the management of painful diabetic neuropathy. METHODS: An open, randomized, comparative study was conducted. Subjects with painful symmetric neuropathy in the lower limbs and mean pain-intensity score > or = 4 on a numeric rating scale were eligible. Subjects were randomized to receive either tramadol (37.5 mg)/acetaminophen (325 mg) or gabapentin (300 mg) for 6 weeks. After 2 weeks of the titration period (1200 mg/day for gabapentin and three tablets/day for T/A), the doses were maintained if the pain was relieved. The primary efficacy outcome was a reduction in pain intensity. Secondary measures evaluated a pain relief scale, a Brief Pain Inventory, a 36-item Short Form Health Survey, average pain intensity and sleep disturbance. RESULTS: One hundred and sixty-three subjects (T/A 79; gabapentin 84) were included. At the final visit, the mean doses were 1575 mg/day for gabapentin and 4.22 tablets/day for T/A. Both groups were similar in terms of baseline pain intensity (mean intensity: T/A 6.7 +/- 1.6; gabapentin 6.3 +/- 1.6, P = 0.168). At the final visit, the mean reductions in pain intensity were similar in both groups (T/A -3.1 +/- 2.0; gabapentin -2.7 +/- 2.1, P = 0.744). Both groups had similar improvements in every Short Form Health Survey category and Brief Pain Inventory subcategory, and in the mean pain relief scores. CONCLUSION: This study suggests that the T/A combination treatment is as effective as gabapentin in the treatment of painful diabetic neuropathy in patients with Type 2 diabetes.

Glabridin, a functional compound of liquorice, attenuates colonic inflammation in mice with dextran sulphate sodium-induced colitis.

Inflammatory bowel disease (IBD) is characterized by detrimental immune reactivity in the gut, and the imbalance between proinflammatory and anti-inflammatory reactivity. The aims of this study were to determine whether oral administration of glabridin, a functional component of liquorice, could ameliorate dextran sulphate sodium (DSS)-induced colitis, as well as to understand the possible underlying mechanisms. Acute experimental colitis was induced in BALB/c mice by treatment with 5% DSS for 7 days. Glabridin (10 or 50 mg/kg/day) was given for 7 days. Treatment with glabridin significantly attenuated mortality, loss of body weight, shortening of the colon and severe clinical symptoms. This was associated with a remarkable amelioration of the disruption of the colonic architecture, a significant reduction in colonic myeloperoxidase (MPO) activity and the production of inflammatory mediators such as nitric oxide (NO), prostaglandin (PG) E2, and proinflammatory cytokines. These results suggest that glabridin-mediated anti-inflammatory action on colorectal sites may be a useful therapeutic approach to IBD.

Different effect of alcohol consumption on hypertension according to metabolic health status.

We aimed to investigate whether the effect of problematic alcohol drinking on hypertension differed according to metabolic health statuses. Male participants from the fifth Korea National Health and Nutrition Examination Survey were recruited. Problematic alcohol drinkers were designated as subjects with heavy drinking (⩾30 g per day), binge drinking (⩾7 glasses per day) or a high alcohol use disorders identification test score (⩾20). Metabolically obese status was defined as having ⩾1 or ⩾2 components of the diagnostic criteria for metabolic syndrome, excluding the blood pressure component. Because the prevalence of problematic alcohol drinking and the prevalence of hypertension largely differed by age groups, separate analyses were performed for the two age groups (<50 and ⩾50 years). Among a total of 6329 subjects, 37.04% had hypertension. In the younger age group, subjects with problematic alcohol drinking demonstrated a higher prevalence of hypertension in both nonobese and obese individuals compared with subjects who were nonobese and who were not problematic alcohol drinkers. Of note, problematic alcohol drinking increased the risk of having hypertension ∼3 times in young nonobese individuals who demonstrated a metabolically obese phenotype compared with those who were metabolically healthy. However, metabolic health status did not have a significant impact on the risk for having hypertension in obese participants, regardless of their age groups. For the prevention of hypertension, avoidance of problematic alcohol drinking should be emphasized, especially in young subjects who show poor metabolic health status despite being nonobese.
