The associations of coffee consumption, coffee types, and caffeine metabolites with periodontitis: Results from NHANES 2009-2014. J Periodontol 2024; 95:778-788. [PMID: 37815812 DOI: 10.1002/jper.23-0322] [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: 05/19/2023] [Revised: 09/14/2023] [Accepted: 09/17/2023] [Indexed: 10/11/2023]
Abstract
BACKGROUND Coffee is one of the world's most popular beverages and is the main dietary source of caffeine for most people. The various molecular effects of caffeine suggest that it may enhance bone loss. The purpose of the present study was to investigate the relationship of coffee, coffee types, and caffeine metabolites with periodontitis. METHODS Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2009-2014. Total coffee and different types of coffee consumption were acquired through a 24-h dietary recall. Urinary caffeine metabolites were quantified using high-performance liquid chromatography-electrospray ionization-tandem quadrupole mass spectrometry (HPLC‒ESI‒MS/MS). The association of coffee, coffee types, and caffeine metabolites with periodontitis and its severity were assessed using multivariable logistic regression. RESULTS A total of 3309 eligible participants were included. After adjusting for potential confounding variables, a positive association was observed between coffee consumption (particularly certain types of coffee) and periodontitis. Notably, a positive correlation was also found between total coffee intake and the severity of periodontitis. Additionally, for urinary caffeine metabolites, there was a significant positive association between 1-methyluric acid (1-MU), 1,3-dimethyluric acid (1,3-DMU), 3,7-dimethyluric acid (3,7-DMU), 1,7-dimethylxanthine (1,7-DMX), or 5-actlyamino-6-amino-3-methyluracil (AAMU) and periodontitis, with adjusted odds ratios and 95% confidence intervals of 1.10 (1.02, 1.19), 1.86 (1.05, 3.29), 0.94 (0.90, 0.98), 1.29 (1.03, 1.62), and 1.15 (1.05, 1.26), respectively. CONCLUSIONS The present study suggests a positive association of coffee intake (especially certain coffee types) and caffeine metabolites (1-MU, 1,3-DMU, 3,7-DMU, 1,7-DMX, and AAMU) with periodontitis and its severity.

Abstract
Aim: This study used urinary caffeine and its metabolites to evaluate their relationships with liver steatosis and advanced liver fibrosis. Methods: A total of 2068 adult participants with required data were filtered from the 2009-2014 National Health and Nutrition Examination Survey (NHANES) cycles. Non-invasive scores were applied to define liver steatosis and advanced liver fibrosis. Logistic regression models, weighted quantile sum (WQS) regression models, quantile-based g-computation (QG-Comp) models, and restricted cubic spline (RCS) regression models were used to assess the associations of urinary caffeine and its metabolites with liver steatosis and advanced liver fibrosis. A series of additional analyses were conducted to examine the subgroup-specific differences and test the robustness of the observed results. Results: The major caffeine metabolite mixture and most individual caffeine metabolites were found to be negatively associated with the risk of advanced liver fibrosis with subgroup-specific variations. Only 7-MX consistently showed a negative association with liver steatosis in all analyses, while no association was observed between the major caffeine metabolite mixture and liver steatosis. Conclusion: The major caffeine metabolite mixture and most individual urinary caffeine metabolites exhibited inverse associations with advanced liver fibrosis with subgroup differences. Further prospective and experimental studies are urgently needed to verify our results and further identify the possible mechanisms.

Abstract
Bone development and lung function are integral to child and adolescent health. Both influence an individual's overall well-being and potentially affect long-term health. Utilizing a comprehensive dataset from the National Health and Nutrition Examination Survey, this study aims to elucidate the relationship between lung function and bone mineral density (BMD) in a representative sample of children and adolescents. The analysis covered 3410 participants aged 8 to 19 years. We employed weighted multivariate linear regression and restricted cubic spline curve visualizations to explore the intricate association between lung function metrics, particularly first-second expiratory volume 1 second/forced vital capacity ratio, and lumbar BMD. Our data indicated a positive association between lung function and lumbar BMD in children and adolescents. Specifically, higher lung function metrics were linked with increased lumbar BMD. This association was more pronounced in younger participants or those with a lower body mass index. A significant positive relationship exists between lung function and BMD in the pediatric population. Recognizing this association is crucial for holistic health strategies for children and adolescents. This study underscores the need for integrated health monitoring during formative years, which can influence health trajectories as these individuals transition to adulthood.

Abstract
The association between coffee intake and bone mineral density (BMD) remains a subject of debate in epidemiological research. Furthermore, the potential relationship between BMD and urine caffeine or caffeine metabolites has not yet been explored. Therefore, the present study aimed to investigate the possible association between BMD and urine caffeine and its metabolites in U.S. adults. We employed multivariate linear and logistic regression models to analyze the relationship between urine caffeine and caffeine metabolites and lumbar BMD using data from the National Health and Nutrition Examination Survey (NHANES) from 2009 to 2014. Additionally, fitted smoothing curves and generalized additive models were used. After adjusting for several factors, we found no significant association between urine caffeine and its metabolites and BMD. However, subgroup analyses stratified by gender and ethnicity showed that the relationship between urine caffeine and its metabolites and lumbar BMD remained consistent. Our investigation revealed that the inflection points for the U-shaped relationship between urinary theophylline and paraxanthine and BMD were observed at levels of 0.006 mmol/L for theophylline and 0.052 mmol/L for paraxanthine. In this cross-sectional study, we found no significant correlation between urine caffeine and its metabolites and BMD. However, more research is required to confirm our findings, as well as to investigate the underlying mechanisms.

Abstract
Hyperuricemia and its complications are severe risks to human health. Dietary intervention is considered an essential part of the management of hyperuricemia. Studies have reported that the intake of antioxidants has a positive effect on hyperuricemia. Here, we collected data from 8761 participants of the National Health and Nutrition Examination Survey for this analysis. Daily intakes of vitamins A, C, and E; manganese; selenium; and zinc were calculated as the composite dietary antioxidant index (CDAI). The participants were divided into four groups (Q1, Q2, Q3, and Q4) according to the CDAI. Univariate analysis was used to assess the association of covariates with hyperuricemia. The association between the CDAI and hyperuricemia was evaluated using multinomial logistic regression, and its stability was determined by stratified analysis. Our results revealed that the CDAI has a significant negative association with hyperuricemia (Q2: 0.81 (0.69, 0.95); Q3: 0.75 (0.62, 0.90); Q4: 0.65 (0.51, 0.82); P < 0.01). The results of stratified analysis emphasize that this association between CDAI and hyperuricemia is stable. In conclusion, this study suggested a negative association between the CDAI and hyperuricemia.

Abstract
INTRODUCTION Hearing loss is a prevalent health concern, and dietary factors, such as fatty acid intake, may play a role in its development. The current study aimed to investigate the association between the intake of dietary fatty acids and hearing thresholds among U.S. adults. METHODS The researchers examined data from the National Health and Nutrition Examination Survey (NHANES), including 7,623 participants with available dietary fatty acid intake and audiometry data. Dietary fatty acid intake was assessed using dietary recalls, and hearing thresholds were measured using pure-tone audiometry. Multivariate linear regression models and smoothing curve fitting were utilized to explore the associations between dietary fatty acid intake and hearing thresholds, adjusting for relevant covariates. RESULTS This study reveals a direct association between both low and high frequency pure tone average (PTA) hearing thresholds and the dietary intake of total saturated fatty acids (SFAs) and total polyunsaturated fatty acids (PUFAs). Conversely, the intake of total monounsaturated fatty acids (MUFAs) demonstrates an inverted U-shaped correlation with low-frequency and high-frequency PTA hearing thresholds, having inflection points at 11.91 (energy (%)) and 10.88 (energy (%)), respectively. CONCLUSION Dietary intake of certain fatty acids may influence hearing thresholds in adults.

Abstract
BACKGROUND This case report presents a patient with pyogenic spondylitis (PS) associated with lactation-related osteoporosis during pregnancy. The 34-year-old female patient experienced low back pain for one month, beginning one month postpartum, with no history of trauma or fever. Dual-energy X-ray absorptiometry of the lumbar spine revealed a Z-score of -2.45, leading to a diagnosis of pregnancy and lactation-associated osteoporosis (PLO). The patient was advised to cease breastfeeding and take oral calcium and active vitamin D. Despite these interventions, her symptoms worsened, and she had difficulty walking one week later, prompting her to revisit our hospital.
CASE SUMMARY Lumbar magnetic resonance imaging (MRI) scans showed abnormal signals in the L4 and L5 vertebral bodies and intervertebral space, while an enhancement scan displayed abnormal enhanced high signals around the L4/5 intervertebral disc, suggesting a lumbar infection. A needle biopsy was performed for bacterial culture and pathological examination, culminating in a final diagnosis of pregnancy and lactation-related osteoporosis with PS. Following treatment with anti-osteoporotic medications and antibiotics, the patient’s pain gradually subsided, and she returned to normal life within five months. PLO is a rare condition that has garnered increasing attention in recent years. Spinal infections during lactation in pregnancy are also relatively uncommon.
CONCLUSION Both conditions primarily manifest as low back pain but require distinct treatments. In clinical practice, when diagnosing patients with pregnancy and lactation-associated osteoporosis, the possibility of spinal infection should be considered. A lumbar MRI should be conducted as needed to prevent delays in diagnosis and treatment.

Abstract
BACKGROUND AND AIM Flavonoids are natural products of plant origin and have been shown to be beneficial for nonalcoholic fatty liver disease (NAFLD) in animal studies. However, relevant epidemiological evidence is still lacking, and the relationship between flavonoid and subclass intake with quantified hepatic steatosis and fibrosis has not been investigated. METHODS AND RESULTS This study was based on the Food and Nutrient Database for Dietary Studies (FNDDS) expanded flavonoid intake database and the National Health and Nutrition Examination Survey (NHANES) 2017-2018 and included a total of 4113 participants with vibration-controlled transient elastography (VCTE) data. Multiple logistic regression was used to assess linear relationships between flavonoids and hepatic steatosis and fibrosis. Smoothed curve fit and a generalized additive model were used to investigate the non-linear relationship, and a two-tailed linear regression model was used to find potential inflection points. Of the 4113 participants, 1045 (25.41%) were diagnosed with NAFLD. After adjusting for energy and major non-dietary covariates, significant linear negative correlations were observed between total flavonoids and CAP [-1.53 (-2.59, -0.47)] and LSM [-0.17 (-0.27, -0.07)]. After adjusting for all covariates, flavones had the strongest and most significant negative association with hepatic steatosis [-1.98 (-3.79, -0.17)]. The results of smooth curve fitting and subgroup analysis demonstrated gender differences, and threshold effect analysis further identified a U-shaped relationship and inflection point between flavonoid intake and hepatic steatosis (infection point: 287.25 mg/d). CONCLUSIONS Our findings suggest negative associations between flavonoid and subclass intake with hepatic steatosis and fibrosis.

Abstract
INTRODUCTION The weight-adjusted waist circumference index (WWI) is a novel obesity evaluation indicator that appears to be superior to body mass index (BMI) and waist circumference (WC) in evaluating muscle and fat mass. The purpose of this study was to investigate the association between WWI and fractures among adults. METHODS In this cross-sectional study, multivariate logistic regression and smoothed curve fitting were used to investigate linear and nonlinear associations between WWI and fractures, based on data from 28,679 adult participants in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. RESULTS After adjusting for all covariates, the prevalence of hip/wrist/spine fractures among all participants was 1.09%, 8.87%, and 1.97%, respectively. A 1-unit increase in WWI was associated with a 5% increase in the odds of hip fractures [1.05 (1.01, 1.10)], and a 9% increase in the odds of spine fractures [1.09 (1.06, 1.13)], but not with the prevalence of wrist fractures [0.97 (0.94, 1.06)]. CONCLUSIONS Higher WWI was associated with an increased prevalence of hip fracture and spine fracture, but not wrist fracture.

Abstract
Introduction The mechanism by which socioeconomic status (SES) affects bone mineral density (BMD) remains unknown, and body mass index (BMI) may be a potential mediator. The purpose of this study was to investigate whether BMI mediates the relationship between SES [education level and poverty income ratio (PIR)] and lumbar BMD and the proportion it mediates. Methods This study included a total of 11,075 adults from the National Health and Nutrition Examination Survey (NHANES). Lumbar BMD was measured at the lumbar spine by dual-energy X-ray absorptiometry (DXA). Multivariate linear regression and smoothing curve fitting were used to investigate the relationship between SES and lumbar BMD. Mediator analysis was used to investigate the proportion of BMI mediating the association between SES and BMD. Results In the fully adjusted model, there was a positive correlation between SES and BMD (education level: β = 0.025, 95% CI: 0.005, 0.045; PIR: β = 0.007, 95% CI: 0.002, 0.011). Mediation analysis showed that BMI mediated the relationship between PIR, education level, and lumbar BMD with a range of mediation proportions from 13.33 to 18.20%. Conclusion BMI partially mediated the positive association between SES and BMD, and this association may be largely mediated by factors other than BMI.

Abstract
INTRODUCTION Inequality in socioeconomic status plays an important role in the prevalence of metabolic diseases in adolescents. The purpose of this study was to explore the association between family income and the degree of hepatic steatosis quantified by vibration-controlled transient elastography (VCTE) among U.S. adolescents. METHODS This cross-sectional study included two cycles of the National Health and Nutrition Examination Survey (NHANES) 2017-2020. Multivariate linear regression and smoothing curve fitting were used to investigate the linear and nonlinear relationship between PIR and hepatic steatosis, respectively. Subgroup analysis and interaction tests were used to test whether this relationship was stable across groups. RESULTS Of the 1,574 adolescent participants, 456 lived in poor households and 307 lived in wealthy households. After adjusting for all covariates, PIR (Ratio of family income to poverty) was significantly negatively associated with the degree of hepatic steatosis [-4.78 (-7.39, -2.17)], and this remained stable after converting PIR to a categorical variable. In addition, this significant negative association was more pronounced in women [-7.62 (-11.38, -3.87)], non-Hispanic blacks [-7.19 (-14.43, 0.06)], Mexican Americans [-6.80 (-13.63, 0.03)], and participants with BMI >30 cm2 [-10.83 (-19.70, -1.96)]. CONCLUSIONS PIR was significantly and negatively associated with the degree of hepatic steatosis in US adolescents. Additional prospective studies are needed to confirm our findings.
