RESUMO
BACKGROUND AND AIM: Decreased kidney function is a putative risk factor for various cancers. However, few studies have investigated the association between a decreased estimated glomerular filtration rate (eGFR) and incident pancreatic cancer. We aimed to investigate the risk of incident pancreatic cancer according to eGFR categories. METHODS: In this retrospective cohort study, we included 359 721 adults who underwent health checkups in 2009 or 2010 by using the Korean National Health Insurance Database. The study population was categorized into four groups by eGFR (mL/min/1.73 m2 ) using the Chronic Kidney Disease Epidemiology Collaboration equation: group 1 (eGFR < 45), group 2 (eGFR ≥ 45 to < 60), group 3 (eGFR ≥ 60 to < 90), and group 4 (eGFR ≥ 90). Multivariate Cox proportional hazards models were used to determine the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the incidence of pancreatic cancer until 2019 by comparing the eGFR groups. RESULTS: During the 3 493 589.05 person-years of follow-up, 1702 pancreatic cancer cases were identified. Compared with group 4 (eGFR ≥ 90), HRs and 95% CIs for the incidence of pancreatic cancer were 1.39 (1.24-1.56) for group 3 (eGFR ≥ 60 to < 90), 1.79 (1.47-2.16) for group 2 (eGFR ≥ 45 to < 60), and 2.05 (1.62-2.60) for group 1 (eGFR < 45) in the multivariate adjusted model. CONCLUSIONS: Decreased eGFR was significantly associated with an increased risk of pancreatic cancer in Korean population. Further studies are needed to investigate the relationship between a decreased eGFR and the risk of pancreatic cancer in other ethnic groups.

BACKGROUND: This study aimed to investigated nutritional status and estimated the adequacy of dietary intake of university students during shipboard internships. METHODS: In this cross- sectional study, data were collected from 25 students out of 42 participants who attended in the research information session in the department of maritime at a university located in Jeonbook, South Korea. The dietary intake data was obtained using the 12-day dietary recall through smartphone photography during the shipboard internships. The data on dietary intake were used to calculate acceptable macronutrient distribution ranges (AMDRs), frequency of inappropriate intake of the 2020 Dietary Reference Intakes for Koreans (KDRIs) as a reference, intake ratio to the nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ). RESULTS: The average age of subjects was 21.68 years and average BMIs in men and women were 25.67 kg/m2 and 23.44kg/m2, respectively. The average energy of men and women was 2018.66 kcal and 1727.87 kcal, respectively. More than half of the subjects did not meet the inappropriate range of the AMDRs for carbohydrates and fat. The NAR of vitamin A, vitamin C, and calcium among all 10 nutrients tended to be lower in both men and women. The MAR were 0.71 and 0.769. On the other hand, in both men and women, vitamin C had the lowest INQ (0.5 and 0.39). For men, grains and potatoes were the major contributors to energy and carbohydrates, and calcium contributed in the order of meat, fish and eggs and vegetables and fruits. Although the highest contributors to energy and carbohydrates for women were grains and potatoes, the contributions from meat, fish, and eggs were similar, and the major contributors to calcium were vegetables and fruits. CONCLUSIONS: To improve the inadequate nutritional status of university students engaged in shipboard internships with the aim of pursuing careers as seafarers, there is a need to provide additional nutritional education tailored to their specific circumstances. Additionally, professional health guidance should be provided to maintain optimal nutritional status.

OBJECTIVES: Although metabolic syndrome (MetS) and its components are defined clinically, those with MetS may have various derangements in metabolic pathways. Thus, this study aimed to evaluate the traits of urine organic acid metabolites indicating the metabolic intermediates of the pathways in the subjects with MetS. METHODS: This cross-sectional study included 246 men and 283 women in a hospital health check-up setting. Urine organic acid metabolites were assayed via high-performance liquid chromatography-mass spectrometry analyses. A high level of each metabolite was defined as the fifth quintile of the distribution. RESULTS: The subjects with MetS had high levels of pyruvate, α-ketoglutarate, α-ketoisovalerate, α-ketoisocaproate, formiminoglutamate, and quinolinate (odds ratios from 1.915 to 2.809 in logistic models adjusted for age and sex). Among the metabolites, pyruvate, formiminoglutamate, and quinolinate were not independent of homeostatic model assessment of insulin resistance (HOMA2-IR). Several metabolites were associated with one or more components of MetS and HOMA2-IR. CONCLUSIONS: Urine organic acid metabolites in MetS are characterized in altered carbohydrate and amino acid metabolism. MetS shared some traits in insulin resistance. These findings may promote the understanding of the pathophysiology of MetS.

It has not been adequately studied which biomarkers for cardiovascular risk indicate changes of atherosclerosis by aging process. The current study aimed to investigate the characteristics of metabolic factors related to arterial stiffness in young and old adults. Our cross-sectional study enrolled 851 healthy young adults and 719 old adults. Metabolic biomarkers included glucose, lipid profiles, and liver enzymes. In young adults, additional biomarkers such as C-reactive protein, apolipoproteins, lipoprotein(a), ferritin, and 25-hydroxycholecalciferol were measured. Arterial stiffness was evaluated by measuring brachial-ankle pulse wave velocity (baPWV). The mean age was 37.8 and 65.1 years old in the young and old groups, respectively. Without adjustment, most parameters were significantly correlated with baPWV in both young and old groups. Mean baPWV was significantly different according to metabolic syndrome (MetS) in both groups (13.1 and 12.1 m/s in the young subjects with and without MetS, respectively; 17.4 and 15.8 m/s, respectively, in the old group). After adjusting for age, sex, and hemodynamic factors, the difference in baPWV according to MetS was significant only in the old group. The relationship between most biomarkers and baPWV was influenced by metabolic disorders such as hypertension and diabetes in old adults. Total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), and apolipoprotein B were significant in young group. In conclusion, the metabolic biomarkers related to arterial stiffness were different between young and old adults. Contrary to old adults, TC, LDLC, and apolipoprotein B were independent biomarkers for arterial stiffness in healthy young adults.

BACKGROUND: This study aimed to evaluate the association between baseline results of the Timed Up and Go (TUG) test and subsequent functional dependency occurrence. METHODS: From the National Health Insurance Service-Senior Cohort database, we identified 39,519 people who participated in the National Screening Program for Transitional Ages at the age of 66 during 2007-2008. Impaired mobility was defined as taking 10 seconds or longer to perform the TUG test. Functional dependency occurrence was defined as the initiation of receiving national Long-Term Care Insurance services-home care or admission to long-term care facilities. Cox proportional hazard regression models were used to assess the hazard ratios (HRs) for dependency occurrence according to baseline TUG test results. RESULTS: The mean follow-up period was 5.7 years. Occurrence rates of dependency were 2.0 and 3.4 cases per 1,000 person-years in the normal and impaired TUG groups, respectively. Impaired mobility was associated with a higher risk of functional dependency occurrence (adjusted HR [aHR], 1.65; 95% confidence interval [CI], 1.40-1.95; P < 0.001). Additionally, in the subgroup analysis for the participants with intact baseline activities of daily living, impaired mobility was associated with a higher risk of dependency occurrence (aHR, 1.65; 95% CI, 1.33-2.04; P < 0.001). CONCLUSION: The TUG test might be a useful predictive marker of subsequent functional dependency occurrence. Intervention to prevent functional dependency may be helpful for older adults with impairment on the TUG test.

PURPOSE: The purpose of this study was to evaluate the association between ascending aortic diameter (AAD) as measured with low-dose chest computed tomography (LDCT) and hypertension in Korean men. METHODS: Korean men (n=1,050) who were screened for lung cancer using LDCT imaging at a health promotion center in Seoul, Korea between January 1 and December 31were recruited for the study. AAD is the longest length of ascending aorta measured from approximately 15 mm above left main coronary ostium to the mid-slice level of the right pulmonary artery. RESULTS: AAD were divided into quartiles, and the degree of hypertension was determined based on the quartiles of the AAD using logistic regression. Odds ratios (OR) for the proportion of hypertension in Q2 (1.70, 95% CI: 1.11-2.59), Q3 (2.72, 95% CI: 1.81-4.09) and Q4 (3.94, 95% CI: 2.63-5.89) were significantly greater than that of Q1 (P for trend < 0.001). Even after controlling for confounding covariates of age, BMI, total cholesterol, HDL-cholesterol, fasting glucose, GGT, ALT, eGFR, smoking status and alcohol intake, there was significant correlation. CONCLUSION: AAD was significantly associated with the degree of hypertension.

BACKGROUND: Visceral fat, including epicardial fat (EF) is recognized as a responsible factor of cardiovascular disease. The aim of this study was to investigate the relationship between EF and diabetes in Korean men. METHODS: EF thickness was measured in the left main coronary artery fat tissue (LMCA-fat) by low-dose chest CT scans in 1,048 Korean men (age above 20 years). LMCA-fat values were divided into quartiles and the prevalence of diabetes was analyzed based on the quartiles of LMCA-fat values using logistic regression. RESULTS: There were significant correlations between LMCA-fat and body mass index (r = 0.169, p = 0.004), waist circumference (r = 0.172, p < 0.001), fasting glucose (r = 0.106, p = 0.037) and HbA1c (r = 0.176, p < 0.001). The patients in the higher LMCA-fat quartiles were associated with higher prevalence of diabetes (p for trend <0.001). Even after adjustment for multiple covariates, this association still remained statistically significant (p for trend = 0.022). The highest LMCA-fat quartile group was significantly associated with diabetes compared to the lowest quartile group. (OR = 3.26, 95% CI = 1.17-9.12). CONCLUSION: These findings indicate that increased EF thickness is independently associated with the prevalence of diabetes in Korean men.

Contrary to the traditional belief that obesity acts as a protective factor for bone, recent epidemiologic studies have shown that body fat might be a risk factor for osteoporosis and bone fracture. Accordingly, we evaluated the association between the phenotypes of osteoporosis or vertebral fracture and variants of obesity-related genes, peroxisome proliferator-activated receptor-gamma (PPARG), runt-related transcription factor 2 (RUNX2), leptin receptor (LEPR), and adiponectin (ADIPOQ). In total, 907 postmenopausal healthy women, aged 60-79 years, were included in this study. BMD and biomarkers of bone health and adiposity were measured. We genotyped for four single nucleotide polymorphisms (SNPs) from four genes (PPARG, RUNX2, LEPR, ADIPOQ). A general linear model for continuous dependent variables and a logistic regression model for categorical dependent variables were used to analyze the statistical differences among genotype groups. Compared with the TT subjects at rs7771980 in RUNX2, C-carrier (TC + CC) subjects had a lower vertebral fracture risk after adjusting for age, smoking, alcohol, total calorie intake, total energy expenditure, total calcium intake, total fat intake, weight, body fat. Odds ratio (OR) and 95% interval (CI) for the vertebral fracture risk was 0.55 (95% CI 0.32-0.94). After adjusting for multiple variables, the prevalence of vertebral fracture was highest in GG subjects at rs1501299 in ADIPOQ (p = 0.0473). A high calcium intake (>1000 mg/day) contributed to a high bone mineral density (BMD) in GT + TT subjects at rs1501299 in ADIPOQ (p for interaction = 0.0295). Even if the mechanisms between obesity-related genes and bone health are not fully established, the results of our study revealed the association of certain SNPs from obesity-related genes with BMD or vertebral fracture risk in postmenopausal Korean women.

Large-scale studies elucidating sex differences in factors impacting prognosis and sex-specific prognossis factors scoring in patients with lung cancer are insufficient. The present study aimed to develop a model to predict sex-specific prognosis factors in Korean patients with lung cancer. This nationwide cohort study included 96,255 patients aged ≥19 years diagnosed with lung cancer and underwent Korean National Health Insurance Service health examinations between January 1, 2005 and December 31, 2015 and followed until 2020. Factors associated with prognosis were estimated using multivariable Cox proportional hazards regression analyses, and separate prognosis scores were calculated for male and female patients. The sex-specific risk scoring models were validated with Kaplan-Meier survival curves and c-statistic. During a mean follow-up of 2.8 years, 60.5% of the patients died. In male patients with lung cancer, age ≥ 65 years (24 points) had the highest mortality risk score, followed by chemotherapy in combination with radiotherapy (16 points), chemotherapy (14 points), and radiotherapy (11 points). In female patients with lung cancer, chemotherapy in combination with radiotherapy (19 points) had the highest mortality risk score, followed by chemotherapy (16 points), age ≥ 65 years (13 points), and radiotherapy (13 points). The analysis of patients categorized into three risk groups based on risk scores revealed that the fatality rates within 5 years were 7%, 54%, and 89% in the low-, intermediate-, and high-risk groups for male patients and 3%, 46%, 85% in the low-, intermediate-, and high-risk groups for female patients, respectively. The c-statistic was 0.86 for male patients and 0.85 for female patients. The strongest fatality risk factors in lung cancer were age ≥ 65 years in male patients and chemotherapy in female patients. The present study developed sex-specific prognosis scoring models to predict fatality risk in patients with lung cancer.

OBJECTIVES: Inconsistent results are available regarding the association between low estimated glomerular filtration rate (eGFR) and lung cancer risk. We aimed to explore the risk of lung cancer according to eGFR category in the Korean population. METHODS: We included 358,293 adults who underwent health checkups between 2009 and 2010, utilizing data from the National Health Insurance Service-National Sample Cohort. Participants were categorized into 3 groups based on their baseline eGFR, as determined using the Chronic Kidney Disease Epidemiology Collaboration equation: group 1 (eGFR ≥90 mL/min/1.73 m2), group 2 (eGFR ≥60 to <90 mL/min/1.73 m2), and group 3 (eGFR <60 mL/min/1.73 m2). Incidences of lung cancer were identified using the corresponding codes from the International Classification of Diseases, 10th revision. Multivariate Cox proportional hazard models were employed to calculate the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for lung cancer incidence up to 2019. RESULTS: In multivariate analysis, group 2 exhibited a 26% higher risk of developing lung cancer than group 1 (HR, 1.26; 95% CI, 1.19 to 1.35). Furthermore, group 3 demonstrated a 72% elevated risk of lung cancer relative to group 1 (HR, 1.72; 95% CI, 1.58 to 1.89). Among participants with dipstick proteinuria of 2+ or greater, group 3 faced a significantly higher risk of lung cancer than group 1 (HR, 2.93; 95% CI, 1.37 to 6.24). CONCLUSIONS: Low eGFR was significantly associated with increased lung cancer risk within the Korean population. A particularly robust association was observed in individuals with severe proteinuria, emphasizing the need for further investigation.

Several lines of evidence indicate that prehypertension is more atherogenic than normal blood pressure. Serum γ-glutamyltransferase (GGT) is known to be positively associated with prehypertensive status and the progression of hypertension. However, there have been no prospective studies of serum GGT level as a predictor of prehypertension. Apparently 13,435 healthy men (mean age 42.0 ± 6.6 yr) with normal blood pressure were included in a prospective cohort study in 2005 and were followed up to 2010 with the endpoint being incident of prehypertension. During the follow up period (median 2.80 ± 1.44 yr; actual follow-up 37,679.1 person-year), prehypertension was developed in 7,867 (58.6%) participants. Risk estimations for incident prehypertension were analyzed based on quartiles of serum GGT levels using multivariate adjusted Cox proportional hazards model. In unadjusted model, the hazard ratio for incident prehypertension for the highest 3 quartiles of baseline serum GGT level was 1.21 (1.13-1.29), 1.29 (1.21-1.38), and 1.57 (1.47-1.67) compared the lowest quartile of serum GGT level, respectively (P for trend < 0.001). These associations still remained statistically significant, even after adjusting for multiple covariates. These findings indicate that increased serum GGT level is independently associated with incident prehypertension in Korean men.

In this study, we examined whether metabolic syndrome (MetS)-related variables are simultaneously affected by sleep quality, premenstrual syndrome (PMS) and dietary consumption. In this cross-sectional study, data for 307 premenopausal women were available. The results showed that women experiencing PMS had significantly lower sleep quality and were more depressed and anxious (p < 0.001 for all). After the subjects were divided into groups according to PMS, the effect of sleep quality on MetS-related variables or MetS components significantly differed; only among women who experienced PMS were poor sleepers significantly higher in waist circumference (p = 0.018) and diastolic blood pressure (p = 0.012) than good sleepers. Among the MetS components, abdominal obesity in women with poor sleep quality was approximately three (16.9% vs. 3.0%, p= 0.020) times more common than in those with good sleep quality. However, these findings were not observed among those who did not experience PMS. Poor sleepers among women experiencing PMS consumed 2.8 times more alcoholic drinks than good sleepers (p = 0.006). The MetS-related variables in Korean women experiencing PMS are associated with sleep quality, and these associations may be modified by dietary habits.
RESUMO
Rice is a major source of carbohydrates. Resistant starch (RS) is digested in the human small intestine but fermented in the large intestine. This study investigated the effect of consuming heat-treated and powdered brown rice cultivars 'Dodamssal' (HBD) and 'Ilmi' (HBI), with relatively high and less than 1% RS content, respectively, on the regulation of glucose metabolism in humans. Clinical trial meals were prepared by adding ~80% HBI or HBD powder to HBI and HBD meals, respectively. There was no statistical difference for protein, dietary fiber, and carbohydrate content, but the median particle diameter was significantly lower in HBI meals than in HBD meals. The RS content of HBD meals was 11.4 ± 0.1%, and the HBD meals also exhibited a low expected glycemic index. In a human clinical trial enrolling 36 obese participants, the homeostasis model assessment for insulin resistance decreased by 0.05 ± 0.14% and 1.5 ± 1.40% after 2 weeks (p = 0.021) in participants in the HBI and HBD groups, respectively. The advanced glycation end-product increased by 0.14 ± 0.18% in the HBI group and decreased by 0.06 ± 0.14% in the HBD group (p = 0.003). In conclusion, RS supplementation for 2 weeks appears to have a beneficial effect on glycemic control in obese participants.

Purpose: Dietary and psychological status contributes to the development of coronary artery disease. However, these lifestyle factors may vary depending on ethnic and environmental background, and secondary prevention programs dealing with these factors in a specific population are not well-established. We aimed to assess dietary and psychological characteristics in Korean patients with acute coronary syndrome (ACS) and analyze their interactions as independent risk factors for ACS. Methods: Ninety-two patients with ACS (29 acute myocardial infarction and 63 unstable angina) and 69 controls were subjected to dietary and psychological analyses. Dietary intake was assessed by a food frequency questionnaire. Psychological depression and perceived stress were assessed using the Patient Health Questionnaire-9 and the Perceived Stress Scale, respectively. Eight domains of life satisfaction (marital/love relationship, leisure, standard of living, job, health, family life, sex life, and self) were assessed using the Domain Satisfaction Questionnaire (DSQ). Results: The ACS group had a higher consumption of sweets and fish/seafood, as well as higher levels of depressive symptoms. Additionally, they had lower DSQ scores in total, and all eight individual domains compared with the control group. In multivariate logistic regression analysis, sweet intake (OR 4.57, 95% CI: 1.94-11.40) and total DSQ scores (OR 0.34, 95% CI: 0.14-0.81) were identified as independent risk factors for ACS. Furthermore, these factors, which displayed a significant inverse correlation (ρ = -0.23, p = 0.01), were determined as having a synergistic contribution to the development of ACS. Conclusion: High sweet food intake and low life satisfaction can act as risk factors for ACS through a synergistic interaction, which emphasizes a demand for a more comprehensive approach to secondary prevention of ACS. In addition, these data highlight the role of positive psychological wellbeing factors in cardiovascular health.
RESUMO
To assess whether a healthy diet could change the risk of cardiovascular disease (CVD)-related chewing difficulty (CD) in relation to age distribution. In a cross-sectional study of 9411 middle-aged Koreans from the KNHANES VII. In this study, the Framingham 10-year general CVD risk prediction equations and the Korean Heathy Eating index (KHEI) were used to assess the 10-year estimated risk of CVD and dietary quality, respectively. CD was experienced by 16.7% of the total subjects. Among subjects with CD, the 10-year estimated CVD risk was 8.71% of the subjects in the 30−49 years age group and 30.38% of those in the 50−64 years age group, which is a difference of approximately 3.5 times. Regardless of age distribution, the total score of the KHEI in subjects who had CD was significantly lower than in those who had no CD (NCD) (p = 0.004 for the 30−49 years age group and p < 0.001 for the 50−64 years age group, respectively). Among the subjects with poor KHEI in the 30−49-year age group, the adjusted odds ratio for the 10-year estimated CVD risk of the subjects with CD was 2.204-fold (95% CI = 1.385−3.506) higher using NCD as a reference. The findings showed that dietary quality could modify the risk for CVD according to chewing status.

Unlike younger adults, depression in older adults is sometimes related to chewing problems. This study examined the risk factors related to depression associated with chewing problems in 3747 elderly individuals using the Korean National Health and Nutrition Examination Survey. Approximately 41.2% of the total subjects reported chewing problems. There were significant differences in age, education, marital status, individual income, current smoking status, and aerobic physical activity in relation to chewing problems (p < 0.001 for all). The subjects who experienced chewing problems showed a higher score on the EuroQoL 5 Dimension index (p < 0.001) but a lower health-related quality of life than those with no chewing problems (p < 0.001). The prevalence of depression, which was classified by the patient health questionnaire-9, in subjects with chewing problems was approximately 2 times higher than that in those with no chewing problems (p < 0.001). Subjects with chewing problems were found to have a 1.945-fold higher adjusted risk of depression than those who did not have chewing problems (95% CI = 1.583-2.390, p < 0.001), and subjects with high protein consumption showed a 1.410-fold greater risk of depression (95% CI = 1.144-1.739, p = 0.001) than those with low protein consumption.

OBJECTIVES: To investigate the prevalence of potentially inappropriate prescribing (PIP) for cardiovascular system (CVS) and antiplatelet/anticoagulant (AP/AC) drugs among Korean elderly patients, using the Screening Tool of Older Persons' Prescriptions (STOPP) criteria version 2 and to identify the risk factors related to PIP. METHODS: The 2016 National Aged Patient Sample data, comprising National Health Insurance claim records for a random sample of 20% of patients aged ≥ 65 years, were used to calculate PIP prevalence of outpatient prescriptions. For criteria including drug-disease interactions, PIP prevalence per indication was estimated. RESULTS: Among 1,274,148 elderly patients and 27,062,307 outpatient prescription claims, 100,085 patients (7.85%) and 341,664 claims (1.27%) had one or more PIP. The most frequent PIP was "non-steroidal anti-inflammatory drug with concurrent antiplatelet agent (s) without proton-pump inhibitor prophylaxis" in the claim-level (0.97%) and patient-level (6.33%) analyses. "Beta-blocker with bradycardia" (16.47% of claims) and "angiotensin receptor blockers in patients with hyperkalaemia" (23.89% of claims) showed the highest PIP prevalence per indication. Logistic regression analysis revealed that, among the patient and health care provider characteristics, female, older age, more severe comorbidities, polypharmacy, higher level of healthcare organization, and specialty of prescriber were significantly associated with a higher risk of PIP. CONCLUSIONS: Our findings of a high prevalence of PIP for CVS and AP/AC drugs among the elderly suggest that an effective strategy is urgently needed to improve the prescription practices of these drugs.
RESUMO
Recent evidence suggests that cellular perturbations play an important role in the pathogenesis of cardiovascular diseases. Therefore, we analyzed the association between the levels of urinary metabolites and arterial stiffness. Our cross-sectional study included 330 Korean men and women. The brachial-ankle pulse wave velocity was measured as a marker of arterial stiffness. Urinary metabolites were evaluated using a high-performance liquid chromatograph-mass spectrometer. The brachial-ankle pulse wave velocity was found to be positively correlated with L-lactate, citrate, isocitrate, succinate, malate, hydroxymethylglutarate, α-ketoisovalerate, α-keto-ß-methylvalerate, methylmalonate, and formiminoglutamate among men. Whereas, among women, the brachial-ankle pulse wave velocity was positively correlated with cis-aconitate, isocitrate, hydroxymethylglutarate, and formiminoglutamate. In the multivariable regression models adjusted for conventional cardiovascular risk factors, three metabolite concentrations (urine isocitrate, hydroxymethylglutarate, and formiminoglutamate) were independently and positively associated with brachial-ankle pulse wave velocity. Increased urine isocitrate, hydroxymethylglutarate, and formiminoglutamate concentrations were associated with brachial-ankle pulse wave velocity and independent of conventional cardiovascular risk factors. Our findings suggest that metabolic disturbances in cells may be related to arterial stiffness.

BACKGROUND AND OBJECTIVES: To assess whether the consumption of dietary macronutrient could change metabolic syndrome (MetS) related to vitamin D deficiency according to menopausal status. METHODS AND STUDY DESIGN: In a cross-sectional study of 8326 Korean women from the Korean National Health and Nutrition Examination Survey V (2010-2012), we investigated the combined interaction effect of serum 25-hydroxyvitamin D [25(OH)D] concentration and menopausal status on MetS-related variables. RESULTS: The prevalence rates of 25(OH)D deficiency (vitamin D <50 nmol/L) among premenopausal and postmenopausal women were 84.5% and 67.9%, respectively. Significant differences in MetS-related variables such as body mass index (P<0.001), waist circumference (P=0.005), fast glucose (P=0.048), triglycerides (P=0.001), and high-density lipoprotein cholesterol (P=0.027) based on 25(OH)D concentration were observed among postmenopausal women but not among premenopausal women. Among the postmenopausal women with high consumption of dietary carbohydrate, the adjusted odds ratios (ORs) [95% confidence intervals (95% CIs)] of MetS among participants with 25(OH)D deficiency increased 1.380-fold (95% CI = 1.086-1.753) using the 25(OH)D-sufficient group as a reference. In contrast, the participants with 25(OH)D deficiency showed an increased risk of MetS [OR (95% CI) = 1.313 (1.041-1.655)] with low-fat consumption. However, the aforementioned findings did not differ among premenopausal women. CONCLUSION: Thus, MetS due to 25(OH)D deficiency among postmenopausal women may be modified by the consumption of dietary macronutrient.
RESUMO
Many postmenopausal women individually experience varying degrees of climacteric symptoms. Among the many influencing factors, body weight and diet are recognized as important contributors to the incidence and severity of these symptoms. This study was performed to investigate the interaction effect of BMI (body mass index) and dietary consumption on the risk of climacteric symptoms among Korean women. Approximately half of the subjects (48.8%) experienced climacteric symptoms. After adjusting for the covariates, the subjects who are overweight or obese showed significantly greater total scores of climacteric symptoms (p = 0.010) and subscales of symptoms (p = 0.027 for physical climacteric symptoms and p = 0.007 for psychological climacteric symptoms), except for urogenital climacteric symptoms (p = 0.085), than those subjects at a normal weight. When subjects were divided into groups according to dietary macronutrient consumption, those who are overweight or obese were 2.84-fold (adjusted odds ratio, 95% CI = 1.18-6.80, p = 0.019) more likely to experience climacteric symptoms than those at a normal weight among the subjects with high fat consumption. However, the BMI category did not affect the adjusted odds ratio for experiencing climacteric symptoms among subjects who consumed a low-fat diet.
