RESUMO
BACKGROUND: The coronavirus disease pandemic is predicted to have adverse health effects on children and adolescents who are overweight or obese due to restricted school activity and stay-at-home orders. The purpose of this observational study was to determine the factors associated with weight gain in children and adolescents with overweight and obesity during coronavirus disease 2019 (COVID-19) lockdown. METHODS: Ninety-seven participants (sex- and age-specific body mass index (BMI) ≥ 85th percentile) were included. A baseline examination was conducted pre-COVID-19 (August 2019 to January 2020), and re-examination was performed post-lockdown (June to September 2020) and the results were compared. Correlation and regression analyses were conducted to investigate the association among changes in cardiometabolic markers and lifestyle behaviors with changes in BMI z-score. RESULTS: During the COVID-19 pandemic, an increase in BMI z-score (2.56 [2.01-2.94] to 2.62 [2.03-3.18]) was noticed in children and adolescents with obesity. Changes in cardiometabolic markers including liver enzymes, triglycerides (r = 0.398), leptin (r = 0.578), and adiponectin (r = -0.326), as well as muscular strength (r = -0.212), were correlated with the increase in BMI z-score. According to a multivariate regression analysis, changes in sedentary time (B = 0.016; 95% confidence interval [CI], 0.001-0.032) and fast-food consumption (B = 0.067; 95% CI, 0.013-0.122) were the lifestyle variables associated with BMI z-score increase. CONCLUSION: Changes in lifestyle behaviors including fast-food consumption and sedentary time during the COVID-19 pandemic may be associated with weight gain. In order to prevent health-related risks in children and adolescents with obesity during the pandemic, it is important to maintain the level of physical activity and healthy dietary habits.

BACKGROUND: The association between obesity and albuminuria in the general population remains unclear. We aimed to identify the association between obesity and albuminuria as well as sex differences regarding the associations using several obesity indices, including waist circumference (WC), body mass index (BMI), and waist-to-height ratio (WHR). METHODS: This study included 3841 subjects (1730 males and 2111 females; age 20-80 years) who participated in the Fifth Korea National Health and Nutrition Examination Survey conducted in 2011. Subjects with hypertension, diabetes, renal failure, or a malignant tumor and those who were pregnant or menstruating were excluded. Albuminuria was defined as a urinary albumin-to-creatinine ratio ≥30 mg/g. Anthropometric parameters were categorized into sex-specific quartiles. Logistic regression models were used to assess the associations between each anthropometric parameter and albuminuria. RESULTS: All of the obesity indices of the fourth quartile group of females showed a twofold higher risk for albuminuria than the second quartile group, and it was persistently significant after adjusting for age, smoking, and physical activity. After further adjustment for high blood pressure and impaired fasting glucose and triglyceride levels, WC and BMI of the fourth quartile group of females still showed a significantly higher risk for albuminuria than the second quartile group (odds ratios 1.96 and 2.24; 95 % confidence intervals 1.03-3.74 and 1.15-4.37). None of the associations between albuminuria and the obesity indices were significant in males. CONCLUSION: Higher WC and BMI were significantly associated with the risk of albuminuria among females, but not males.

BACKGROUND: Previous studies reported mixed results regarding the association between cognition and body weight in late life. We evaluated the relationships between cognitive function and body composition among community-dwelling older adults. METHODS: Three hundred twenty subjects (≥65 years, women 53%) with available data of cognitive function and body composition from 2010 Hallym Aging Study. Cognitive function was assessed using Korean Mini-Mental State Examination (K-MMSE). Dual-energy X-ray absorptiometry (DEXA) was used for measuring body composition including body fat and lean body mass. Anthropometric measurements and laboratory data were collected in clinical examination. Body composition variables were divided into sex-specific tertiles, and examined by multivariable logistic regression. RESULTS: Among female, the highest tertile group of fat mass and second tertile group of total lean body mass were associated with lower risk for cognitive impairment compared to the respective first tertile groups (odds ratios, 0.23 and 0.09, respectively; 95% confidence intervals, 0.04-0.88 and 0.01-0.44, respectively) after adjusting for confounding factors. In male, higher arm bone mineral content was associated with lower risk for cognitive impairment, but significance was lost after adjusting for adiponectin, age, and education. CONCLUSIONS: Higher fat mass and lean body mass were associated with lower risk of cognitive impairment in older women. These observations suggest that body fat and lean mass later in life might be beneficial for cognition.

BACKGROUND AND STUDY AIMS: Oral sodium phosphate (OSP) is a cleansing agent for colonoscopy. Recent reports have cited an increased risk of acute renal failure (ARF) in OSP bowel purgative users, but this risk remains under debate. This study was performed to evaluate the association between OSP and ARF in patients who underwent colonoscopy. PATIENTS AND METHODS: A population-based case-crossover study was conducted using the Korean Health Insurance Review and Assessment Service (HIRA) claims data from 1 January 2005 to 31 December 2009. The study population consisted of patients agedâ≥â50 years who underwent colonoscopies after an OSP prescription prior to their first hospitalization for ARF. For each patient, one hazard and four control periods were matched at specified time windows. Conditional logistic regression analysis was used to estimate the odds ratio (OR) and 95â% confidence interval (CI), adjusting for concomitant medications that could induce ARF. RESULTS: A total of 1105 patients were included (54â% male). The adjusted ORs for ARF related to the use of OSP when applying the 1-, 2-, 4-, 8-, or 12-week time windows were 3.7 (95â%CI 2.37â-â5.67), 3.5 (95â%CI 2.45â-â4.89), 3.0 (95â%CI 2.30â-â3.95), 2.4 (95â%CI 1.93â-â2.96), and 2.0 (95â%CI 1.69â-â2.46), respectively. When adopting an 8-week time window, the adjusted OR was 2.5 (95â%CI 1.98â-â3.16) for the subgroup without chronic renal failure. CONCLUSIONS: The use of OSP was significantly associated with ARF both in patients with and without co-morbidities.

OBJECTIVE: To investigate the relationship between hypertension and fruit intake in an Asian population. METHOD: This study was based on the data from 2007, 2008 and 2009 Korea National Health and Nutrition Examination Survey. In the final analysis, a total of 9791 subjects (men=3819, women=5972) were included. Daily energy and nutrient intakes were assessed using 24-h recall. The odds ratios (ORs) for hypertension were assessed by using logistic regression and multivariable models. RESULTS: A total of 10.6% of individuals were classified as having hypertension. Compared with the lowest quintile of fruit intake, the fifth quintile showed the lowest likelihood of hypertension (OR 0.73; 95% confidence interval [CI], 0.61-0.88) after adjusting for age and gender. For women, the likelihood of hypertension in the 2nd, 3rd, 4th and 5th quintiles of fruit intake decreased to 0.67 (95% CI, 0.34-1.30), 0.76 (0.56-1.05), 0.90 (0.67-1.22) and 0.54 (0.38-0.77), respectively, after adjusting for confounding factors (P value for trend=0.0011). An inverse association of fruit intake and hypertension was shown only in non-obese women. For men and obese women, there was no relationship between fruit intake and hypertension. CONCLUSION: Dietary fruit recommendation for hypertension should be taken into account together with ethnic background, gender as well as the presence of obesity in individuals.

BACKGROUND: Body composition changes with ageing can influence the adiponectin concentration. However, the component of body composition that is associated with adiponectin concentrations in older adults remains unclear. METHODS: There were 152 males and 168 females aged 65 years or older that participated in the 2010 Hallym Aging Study (HAS). Body composition (assessed by dual energy X-ray absorptiometry; DXA), anthropometric parameters and adiponectin were obtained from all participants. Multivariate linear regression models assessed the association of body fat percentage, regional muscle and bone mineral contents of body composition and waist/height ratio with adiponectin concentration. Age, albumin, testosterone concentration and metabolic parameters were considered as confounding factors. RESULTS: In correlation analysis, age was positively associated with adiponectin in males (P < 0.01), but not in females. Fasting glucose, albumin, arm skeletal muscle mass and bone mineral content were negatively associated with adiponectin in males (P < 0.05). Testosterone and leg bone mineral content were negatively associated with adiponectin in females (P < 0.05). In multivariate linear regression models, body fat percentage and albumin (P < 0.05) were negatively associated with adiponectin, and high-density lipoprotein cholesterol (HDL-C) (P < 0.001) and age (P < 0.01) were positively associated with adiponectin in older males. In older females, the only factors that correlated significantly with adiponectin concentration were the homeostasis model assessment of insulin resistance (P < 0.001) and HDL-C (P < 0.05). The waist/height ratio and bone mineral content were not associated with adiponectin in either gender. CONCLUSION: Plasma adiponectin levels correlated negatively with body fat percentage in older males but not in older females. The differential results between older males and females suggest that certain gender-specific mechanisms may affect the association between adiponectin and age-related body composition changes.

Galectin-3 levels have been studied as a potential biomarker for predicting cardiovascular (CV) risk and mortality in hemodialysis (HD) patients. Recently, a close relationship between galectin-3 and vascular calcification (VC) has been reported. Here, we investigated the role of VC as a mediating factor in the association between galectin-3 and mortality. Serum galectin-3 and baseline aortic arch calcification (AoAC) score were measured in 477 incident HD patients. Mortality data were obtained at a median follow-up of 40 months. Causal mediation analysis was performed to examine the effect of vascular risk factors on galectin-3-related mortality. The prevalence of AoAC in HD patients was 57% (n = 272), and elevated galectin-3 levels were associated with a significantly increased risk of AoAC. When the galectin-3 level was divided by the median level of 37 ng/mL, a higher galectin group increased the risk of all-cause mortality by 1.71-fold (95% CI 1.02-2.92, p = 0.048), even after adjustment for multiple CV risk factors. Mediation analysis showed that both the direct effect of the galectin-3 on mortality (ß = 0.0368, bootstrapped 95% CI [0.0113-0.0622]) and the indirect effects were significant. AoAC score and high-sensitivity CRP levels significantly mediated the association between galectin-3 and mortality (total indirect effects: ß = 0.0188, bootstrapped 95% CI [0.0066-0.0352]). This study suggests that the association between high galectin-3 and mortality may be partially mediated by higher VC and inflammatory state in HD patients.

AIM: The initial decrease in estimated glomerular filtration rate (eGFR), often known as the "initial dip," associated with sodium-glucose cotransporter 2 inhibitors (SGLT2i) is typically transient but may be more pronounced in older patients. METHODS: We analyzed real-world data from 2,070 patients newly prescribed SGLT2i, tracking eGFR changes at baseline and 3, 6, 9, and 12 months after initiation. We defined a significant initial dip as over 10 % reduction in eGFR at 3 months. In addition, the 1-year change in eGFR after the initial decline was also assessed. RESULTS: Of the total patients, 34.5 % were aged 60-69 years, 21.1 % were aged 70-79 years, and 11.5 % were aged 80 years or older. About 21.4 % experienced a significant dip at 3 months. The incidence of initial dip increases with age, with the highest incidence (38.7 %) in those aged 80 + . Despite the initial decline, subsequent eGFR was stable over one year in all age groups. Factors such as age, lower hemoglobin, higher uric acid levels, and use of RAS blockers were linked to the initial dip. CONCLUSIONS: Older patients showed a more pronounced initial eGFR decline after starting SGLT2i, but it stabilized for one year without further deterioration, similar to younger patients.

Sarcopenia is defined as an age-related decline in muscle mass, muscle strength, and physical performance. Eating alone has been linked to various health issues in older adults. This study investigated the relationship between eating alone and handgrip strength (HGS) in older adults using data from 7278 individuals (≥65 years) who participated in the 2014-2019 Korea National Health and Nutrition Examination Survey. HGS was measured using a digital grip strength dynamometer, relative HGS was calculated by dividing HGS by body mass index, and dynapenia was defined as an HGS < 28 kg for men and <18 kg for women. Multivariable logistic regression analysis showed that women who ate two meals alone were more likely to exhibit dynapenia than those who never ate alone (odds ratio [OR], 1.3; 95% confidence interval [CI], 1.03-1.77). If the groups that never ate alone or ate one meal alone were combined as the reference group, the probability of dynapenia was higher in the combined groups that ate two or three meals alone (OR, 1.25; 95% CI, 1.04-1.50). No association was observed between eating alone and dynapenia in men. This suggests that eating alone is a modifiable related factor of dynapenia in older women.

BACKGROUND: Vitamin C is a commonly used antioxidant supplement; however, its effects on obesity and fat distribution are equivocal. We examined nationally representative data to determine whether intake of vitamin C is related to abdominal obesity. METHODS: In total, 16,414 adults (58 % women) from the 2007 - 2010 Korea National Health and Nutrition Examination Survey were included in the analysis. Vitamin C intake was calculated using 24-hour recalls and categorized into quintiles. The multivariate models in logistic regression analysis were adjusted for age, energy intake, sodium intake, smoking, alcohol consumption, physical activity, education, income, pre-existing disease conditions, survey year, and menopausal status (in women only). RESULTS: Compared with the lowest quintile (Q1) of vitamin C intake, the adjusted odds ratios of Q2, Q3, Q4, and Q5 for abdominal adiposity were 0.92, 0.86, 0.81, and 0.70, respectively, in women (p for trend = 0.0007). This association was maintained after adjusting for the confounding factors; however, we observed no association between intake of vitamin C and abdominal obesity in men. CONCLUSIONS: Vitamin C intake showed a negative association with abdominal obesity in women. Further research is warranted on the association between and the mechanism of vitamin C in abdominal obesity.

BACKGROUND/OBJECTIVES: This study aimed to identify the factors associated with short- or long-term non-response to an obesity intervention in children and adolescents. SUBJECTS/METHODS: In this observational study, a total of 242 children and adolescents (sex- and age-specific body mass index (BMI) ≥ 85th percentile) were divided into three groups according to the BMI z-score change after 6 (n = 163) and 24 months (n = 110) of participating in an obesity intervention: responders, low responders, and non-responders if the BMI z-score decrease was ≥0.25, 0 to 0.25, and if it increased, respectively. RESULTS: Short-term non-response was associated with higher maternal psychosocial stress (OR = 2.34, 95% CI [1.07-5.11]) and adolescence (>11 years; OR = 2.40, 95% CI [1.10-5.22]). The odds of long-term non-response were reduced by an increased vegetable consumption of more than five dishes per week (OR = 0.21, 95% CI [0.07-0.69]) and an hour of increased sleep duration during weekends (OR = 0.14, 95% CI [0.04-0.53]). CONCLUSIONS: Short-term non-response was associated with child and maternal characteristics, whereas long-term non-response was associated with actual lifestyle changes such as sleep duration and vegetable consumption. Children with obesity may benefit from an hour of weekend catch-up sleep in lowering the risk of long-term treatment non-response. An individualized approach should be considered for children of older age and mothers with a higher level of stress, as they may not benefit from a conventional short-term lifestyle intervention.

This was a cross-sectional study conducted to evaluate the association between hearing impairment and low back pain (LBP) using data from the Korean National Health and Nutrition Examination Survey. A total of 5,504 middle-aged and older Korean adults (aged ≥50 years old) who underwent plain radiography of the lumbar spine and pure tone audiometry were included. The presence of LBP was evaluated using a questionnaire, which included a question on whether the patient had experienced LBP that lasted for more than 30 days during the past three months. Patients with age-related hearing loss (ARHL) were defined as those with bilateral hearing impairment who met the following criteria: 1) normal otologic examination results, 2) average pure-tone hearing thresholds of ≤15 dB in both ears, and 3) no occupational noise exposure. Multivariable logistic regression analysis showed that ARHL was not associated with LBP (odds ratio, 1.33; 95% CI, 0.94-1.89) after adjusting for potential confounders in the final model. However, when participants without both ARHL and tinnitus were defined as the reference group, the results showed that the participants with both ARHL and tinnitus were more likely to have LBP (OR, 1.86; 95% CI, 1.11-3.11). These results indicate that ARHL with tinnitus is significantly associated with LBP. We recommend that elderly patients with ARHL and tinnitus increase their daily physical activities and engage in more muscle-strengthening exercises to prevent LBP.

BACKGROUND: Chronic heart failure accounts for a great deal of the morbidity and mortality in the aging population. Evidence-based treatments include angiotensin-2 receptor blockers (ARBs), angiotensin-converting enzyme inhibitors (ACE-I), beta-blockers, and aldosterone antagonists. Underutilization of these treatments in heart failure patients were frequently reported, which could lead to increase morbidity and mortality. The aim of this study was to evaluate the utilization of evidence-based treatments and their related factors for elderly patients with chronic heart failure. METHODS: This is retrospective observational study using the Korean National Health Insurance claims database. We identified prescription of evidence based treatment to elderly patients who had been hospitalized for chronic heart failure between January 1, 2005, and June 30, 2006. RESULTS: Among the 28,922 elderly patients with chronic heart failure, beta-blockers were prescribed to 31.5%, and ACE-I or ARBs were prescribed to 54.7% of the total population. Multivariable logistic regression analyses revealed that the prescription from outpatient clinic (prevalent ratio, 4.02, 95% CI 3.31-4.72), specialty of the healthcare providers (prevalent ratio, 1.26, 95% CI, 1.12-1.54), residence in urban (prevalent ratio, 1.37, 95% CI, 1.23-1.52) and admission to tertiary hospital (prevalent ratio, 2.07, 95% CI, 1.85-2.31) were important factors associated with treatment underutilization. Patients not given evidence-based treatment were more likely to experience dementia, reside in rural areas, and have less-specialized healthcare providers and were less likely to have coexisting cardiovascular diseases or concomitant medications than patients in the evidence-based treatment group. CONCLUSIONS: Healthcare system factors, such as hospital type, healthcare provider factors, such as specialty, and patient factors, such as comorbid cardiovascular disease, systemic disease with concomitant medications, together influence the underutilization of evidence-based pharmacologic treatment for patients with heart failure.

OBJECTIVE: This study aimed to compare how children with overweight or obesity and their parents perceive the obesity-related terms used by healthcare professionals and investigate the factors associated with these perceptions. METHODS: Children and adolescents aged 8-16 years with overweight or obesity (n = 192) and their parents participated in the cross-sectional study by responding to a 5-point Likert-scale questionnaire on 10 obesity-related terms, including "chubby," "weight problem," "weight," "overweight," "BMI," "obese," "heavy," "fleshy," "fat," and "severely obese." RESULTS: For both children and parents, "chubby" was the most desirable term (mean ± standard deviation: 3.50 ± 1.12 and 2.95 ± 0.83, respectively), and "severely obese" was the least acceptable term (2.83 ± 1.17 and 2.02 ± 1.02, respectively). Although the parents preferred all the terms less than the children did (p < 0.001), "weight problem" was considered most motivating for a child to lose weight (3.93 ± 0.94). Among children, older age and a larger self-perceived body size were associated with a more positive response towards obesity-related terms, whereas having internalized or externalized problems were negatively associated with these terms. Parents with a history of cardiovascular disease considered "severely obese" (ß = -0.419, [95% CI: -0.739, -0.099]) and "fat" (ß = -0.457, [95% CI: -0.750, -0.164]) less desirable. CONCLUSIONS: Children and adolescents had a higher preference for obesity-related terms than their parents and preferred that healthcare professionals use euphemistic terms such as "chubby," or neutral terms such as "weight problem." Children with larger self-perceived body sizes or older age had a higher preference for obesity-related words. The terms used by healthcare professionals to describe excess weight must be motivating and respectful for all family members participating in the treatment.

The COVID-19 pandemic is a global health threat. Smoking and smoking-related lung diseases are risk factors for severe COVID-19 infection. This study investigated whether low-dose computed tomography (LDCT) scan results affected the success of 1-year smoking cessation. The Gyeonggi Southern Smoking Support Center performed the residential smoking cessation program from January to December 2018. During the program, LDCT was performed on 292 participants; 6 months later, follow-up via telephone or visit was conducted. Among the 179 participants who succeeded in smoking cessation for 6 months, telephone follow-up was conducted to determine whether there was a 12-month continuous smoking cessation. In order to evaluate the association between LDCT results and 12-month continuous abstinence rate (CAR), logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI). The CARs at 6 and 12 months were 61.3% and 31.5%, respectively. Indeterminate or suspicious malignant lung nodules were associated with a higher 12-month CAR (OR, 3.02; 95% CI, 1.15-7.98), whereas psychiatric history was associated with a lower 12-month CAR (OR, 0.06; 95% CI, 0.03-0.15). These results suggest that abnormal lung screening results may encourage smokers to quit smoking.

This study aimed to evaluate the effect of dietary protein intake and regular exercise on low back pain (LBP) using data from the Korea National Health and Nutrition Examination Survey. A total of 2367 middle-aged and older adults (≥50 years) who underwent dual-energy X-ray absorptiometry and plain radiography of the lumbar spine were included. LBP was defined using a questionnaire to determine the presence of LBP lasting more than 30 days in the preceding three months. Twenty-four-hour dietary recall data were used to estimate protein intake, and regular exercise was assessed using the International Physical Activity Questionnaire. Multivariable logistic regression analysis revealed that men who did not perform regular exercise had a high probability of LBP (odds ratio [OR] 2.34; 95% confidence interval [CI] 1.24−4.44). Low protein intake (<0.8 g/kg/day) was associated with high odds for LBP in women (OR 1.83; 95% CI 1.12−2.99). Low protein intake and lack of regular exercise were also associated with a higher probability of LBP in women (OR 2.91; 95% CI 1.48−5.72). We recommend that women over 50 years of age consume the recommended daily amount of protein to prevent LBP and engage in regular exercise.
RESUMO
BACKGROUND: Eating alone is a critical factor in nutritional risk screening among older adults. We investigated whether changes in eating status (eating alone or with others) in late-life affected cognitive decline in community-dwelling older adults. METHODS: We used data from the Survey of the Living Conditions and Welfare Needs of Korean Older Persons. Nutritional risk, including eating status, was assessed using seven questions from the Nutrition Screening Initiative checklist, and cognitive function was measured using the Mini-Mental State Examination (MMSE). On the basis of changes in eating status between baseline (2008) and the 3-year follow-up (2011), the subjects were divided into four groups: group 1 (eating with others at both visits), group 2 (eating alone in 2008 and eating with others in 2011), group 3 (eating with others in 2008 and eating alone in 2011), and group 4 (eating alone at both visits). Generalized linear models were used to compare the changes in MMSE scores over the 3-year period among the four groups. RESULTS: Among older women, group 2 had the least decline in MMSE scores (-0.55±0.46), whereas group 3 had the greatest decline (-1.76±0.37) (p=0.034). We observed no difference in the change in MMSE scores among the four eating groups in older men. CONCLUSION: Deprivation of mealtime partners in late life enhanced cognitive decline compared with gaining mealtime partners. Eating alone may be a risk factor for cognitive impairment; thus, meal programs reinforcing social integration might help preserve cognitive function.
RESUMO
We investigated whether clinical factors including comorbidities, medications, and laboratory results predict inpatient fall risk in older adults. The participants in this case-control study included hospitalized older adults with acute conditions who had falls during their hospital stay (case group) and 410 hospitalized older adults who did not experience falls (control group). Data on medical history, fall risk assessment (Morse Fall Scale; MFS), medications, and laboratory results were obtained. Conditional logistic regression analysis was performed to estimate the association between clinical factors and falls. Receiver operating characteristic curves and area under the curve (AUC) were used to determine whether clinical factors could discriminate between fallers and controls. We evaluated three models: (M1) MFS, (M2) M1 plus age, sex, ward, and polypharmacy, and (M3) M2 plus clinical factors. Patients with diabetes mellitus or MFS scores ≥ 45 had the highest risk of falls. Calcium channel blockers, diuretics, anticonvulsants, and benzodiazepines were associated with high fall risk. The AUC of the three models was 0.615, 0.646, and 0.725, respectively (M1 vs. M2, P = 0.042 and M2 vs. M3, P < .001). Examining clinical factors led to significant improvements in fall prediction beyond that of the MFS in hospitalized older adults.

Mixed results have been reported regarding whether habitual tea intake affects bone health. This study investigated the relationship between green tea intake and bone mineral density (BMD) in postmenopausal Korean women. We used data from the Korean National Health and Nutrition Examination Surveys from 2008 to 2011 and divided the participants into three groups according to their frequency of green tea intake over the past 12 months. BMD of the lumbar spine, total femur, and femur neck was measured using dual-energy X-ray absorptiometry. The odds ratios (ORs) and 95% confidence intervals (CIs) of osteoporosis and osteopenia according to green tea consumption were analyzed. Participants who did not consume green tea or consumed less than one cup per day were more likely to have osteopenia of the lumbar spine or femur than those who consumed it once to three times a day (OR 1.81 and 1.85, 95% CI, 1.20-2.71; and 1.23-2.77). Moreover, ORs for osteoporosis were 1.91 (95% CI 1.13-3.23) and 1.82 (95% CI 1.09-3.05) in non-consumers and consumers who drank less than one cup per day, respectively, compared with the reference group. These results support that green tea consumption may have benefits on bone health.

BACKGROUND: The present study evaluated the associations of the fat-to-muscle ratio (FMR) with metabolic syndrome (MetS) and insulin resistance (IR) in Korean adults using nationally representative survey data. METHODS: A two-stage stratified sampling method was reflected in a cross-sectional study involving a total of 13 032 participants aged ≥ 19 years who participated in the fourth and fifth Korea National Health and Nutrition Examination Surveys. The homeostasis model assessment for IR (HOMA-IR) was used to evaluate IR and was calculated as follows: [fasting plasma glucose level (mg/dL) × fasting plasma insulin level (uIU/mL)]/405. MetS was defined using the 2006 International Diabetes Federation criteria, and FMR was measured using whole-body dual-energy X-ray absorptiometry and calculated as follows: total fat mass (kg) divided by total lean mass (kg). In addition, the optimal FMR cut-off values for detecting MetS and the odds ratios (ORs) for MetS risk were determined according to the FMR quartile and sex. RESULTS: Among all participants, the proportion of women was 58.4%, and the mean age was 44.22 ± 0.26 years. The FMR significantly differed between men and women (0.30 ± 0.002 vs. 0.53 ± 0.003, respectively, P < 0.001), and the prevalence of MetS and IR gradually increased as FMR increased (P for trend: <0.001). The optimal FMR cut-off value for detecting MetS was higher in women than in men (0.555 vs. 0.336, respectively). The negative predictive value was the highest in normal-weight participants (0.9992 in women and 0.9986 in men), while the positive predictive value was the highest in obese participants (0.5994 in women and 0.5428 in men). Based on the derived cut-off FMR, a high FMR was associated with poor outcomes in terms of cardiometabolic risk markers (P < 0.001). The multivariable-adjusted ORs for MetS, abdominal obesity, and IR (HOMA-IR ≥ 3) were 5.35 [95% confidence interval (CI): 4.39-6.52], 7.67 (95% CI: 6.33-9.30), and 3.25 (95% CI: 2.70-3.92), respectively, in men and 5.59 (95% CI: 4.66-6.72), 7.48 (95% CI: 6.35-8.82), and 2.55 (95% CI: 2.17-3.00), respectively, in women. CONCLUSIONS: In the present study, a high FMR was significantly associated with the prevalence of MetS and IR. The present findings also showed that FMR can be a novel indicator for detecting the absence or presence of MetS, particularly in metabolically healthy normal-weight individuals and metabolically obese obese-weight individuals.
