Oral health and physical performance in Asian military males: The cardiorespiratory fitness and health in armed forces.

Background/purpose: It is unclear about whether the oral health has impact on physical performance. Therefore, this study aimed to examine the association between oral health and physical performance in 300 military adults in Taiwan. Materials and methods: Oral health was assessed by the presence of periodontitis and dental caries. The status of cardiorespiratory and muscular endurance capacity was respectively assessed by tertiles of time for a 3000-m run and 2-min push-up numbers. Multivariable logistic and linear regression analyses with adjustments for age, smoking, alcohol drinking, blood pressure, anthropometric variables, lipid profile, fasting glucose and physical activity were used to determine the association. Results: Participants with periodontitis were more likely to have worse 3000-m running performance classified in the lowest tertile [odds ratio (OR) and 95% confidence interval: 1.94 (1.03, 3.66)]. Participants with any dental caries were more likely to have worse push-ups performance classified in the lowest tertile [OR: 2.50 (1.27, 4.92)]. In linear regression analyses, dental caries numbers were inversely correlated with 2-min push-ups numbers [ß = -1.04 (-2.07, -0.01)]. Conclusion: This study suggests that oral health is crucial to maintain physical fitness, and dental caries and periodontitis may affect differently on aerobic and muscular endurance capacities.

Does the guideline-based physical activity level for cardiovascular health also benefit periodontal health?

Abstract Background/purpose: It is unclear about whether the guideline-based physical activity (PA) level for cardiovascular health also benefits periodontal health. Therefore, this study aimed to clarify the association between guideline-based PA levels and periodontitis in young adults. Materials and methods: This was a cross-sectional study which included 334 military participants, aged 18-44 years in Taiwan. The PA level was assessed by total running time per week (wk) in the past 6 months from a self-reported questionnaire, and was classified as moderate intensity PA <150, 150-299, and ≥300 min/wk according to the American guideline for cardiovascular health. Periodontitis was defined based on the 2017 World Workshop. Multiple logistic regression analysis was used to determine the association with adjustment for age, sex, educational level, tobacco smoking, alcohol intake, body mass index, waist circumference, blood pressure and teeth brushing frequency. Results: As compared to the PA: 150-299 min/wk, the PA <150 min/wk was associated with a greater possibility of periodontitis (odds ratio (OR): 2.45 (95% confidence interval (CI): 1.24-4.82), whereas the PA ≥300 min/wk was not associated with periodontitis (OR: 0.98 (95% CI: 0.13-1.09)) in young adults. Conclusion: The guideline-based moderate intensity PA level ≥150 min/wk is found to have superior periodontal health in young adults. However, there is no additional benefit in more exercise time to obtain better periodontal health when the suggested PA level has been achieved.

Association between secondhand smoke exposure and incident heart failure: The Multi-Ethnic Study of Atherosclerosis (MESA).

AIMS: There are no studies on the association between secondhand smoke (SHS) exposure and incident heart failure (HF). This cohort study aimed to examine the associations of self-reported and urinary cotinine-assessed SHS exposure with incident HF. METHODS AND RESULTS: This study included 5548 non-active smoking participants aged 45-84 years and free of known cardiovascular diseases and HF at baseline who self-reported SHS exposure time in the Multi-Ethnic Study of Atherosclerosis (MESA) at baseline (2000-2002). A cohort subset of 3376 non-active smoking participants underwent urinary cotinine measurements. HF events were verified by medical records or death certificates and ascertained from baseline through 2019. Multivariable Cox proportional hazards regression analysis was used with adjustment for demographic variables, traditional cardiovascular risk factors, physical activity, tobacco pack-years and medications. During a median follow-up of 17.7 years, 353 and 196 HF events were identified in the self-report cohort and cohort subset, respectively. In the self-report cohort, compared with the SHS unexposed group (0 h/week), the highest tertile of the SHS exposed group (7-168 h/week) was not associated with incident HF (hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.49-1.00; p = 0.052). In contrast, in the cohort subset, participants with detectable urinary cotinine >7.07 ng/ml had a higher risk of incident HF than those with undetectable urinary cotinine ≤7.07 ng/ml (HR 1.45, 95% CI 1.03-2.06; p = 0.034). There were no significant heterogeneities in HF risk by age, sex, race/ethnicity, or past smoking status. CONCLUSION: Secondhand smoke exposure reflected by modestly increased urinary cotinine (>7.07 ng/ml) rather than self-report in non-active smokers was associated with a 40-50% higher risk of any HF event.

Do the American guideline-based leisure time physical activity levels for civilians benefit the mental health of military personnel?

Backgrounds: This study aimed to clarify the association of American guideline-based leisure time physical activity (PA) level with mental health in 4,080 military personnel in Taiwan. Methods: The moderate intensity PA level was assessed according to the total running time per week (wk) reported in a self-administered questionnaire over the previous 6 months and was categorized into PA level <150, 150-299, and ≥300 min/wk. Mental stress was assessed by the Brief Symptom Rating Scale (BSRS)-5 for which ≥15 points were classified as great mental stress. Suicide ideation (SI) was graded as 1 for mild, 2 for moderate, and 3 or 4 for severe. Multivariable logistic regression analysis was employed to determine the association between PA and mental health while adjusting for demographics, smoking, alcohol intake, betel nut chewing, and obesity. Results: As compared to participants with a PA level of <150 min/wk., those with PA levels 150-299 min/wk. and ≥ 300 min/wk. had a lower possibility of SI ≥1 [odds ratios (ORs) and 95% confidence intervals (CIs): 0.58 (0.40-0.83) and 0.23 (0.14-0.36), respectively] and SI ≥1 and/or BSRS-5 ≥ 15 [ORs: 0.55 (0.39-0.79) and 0.21 (0.13-0.34), respectively]. The possibilities were more significantly lower for SI ≥2 [ORs: 0.37 (0.20-0.68) and 0.10 (0.04-0.26), respectively] and SI ≥2 and/or BSRS-5 ≥ 15 [ORs: 0.35 (0.20-0.62) and 0.10 (0.04-0.25), respectively]. Conclusion: Our findings indicate that participating in moderate-intensity leisure time PA level for ≥150 min/wk. may have a positive effect on mental health among military personnel. The impact appears to be even more significant when engaging in a higher PA level of ≥300 min/wk.

Immediate impact of Mindfulness-Based Cognitive Therapy (MBCT) among women with breast cancer: a systematic review and meta-analysis.

BACKGROUND: Mindfulness-based cognitive therapy (MBCT) may have positive physiological and psychological benefits for breast cancer survivors. However, few studies involved a combination of the relevant literatures to confirm the effects. METHODS: Our study included randomized controlled trials (RCTs) and non-RCTs comparing interventions of MBCT and control protocols for alleviation of symptoms among breast cancer survivors. We calculated pooled mean differences (MDs), standardized mean differences (SMDs), and 95% confidence intervals (CIs) by using random effects models to estimate summary effect sizes. RESULTS: Thirteen trials with 20-245 participants were considered in our studies; for the meta-analysis, 11 of these studies were eligible for assessment. The pooled meta-analysis results revealed that at the end of the MBCT intervention, participants' anxiety (SMD, - 0.70; 95% CI, - 1.26 to - 0.13; I2 = 69%), pain (SMD, - 0.64; 95% CI, - 0.92 to - 0.37; I2 = 0%), and depression (SMD, - 0.65; 95% CI, - 1.14 to - 0.17; I2 = 75%) levels significantly decreased, and their mindfulness (MD, 8.83; 95% CI, 3.88 to 13.78; I2 = 68%) levels significantly increased. CONCLUSION: The MBCT may be associated with improved pain, anxiety, depression, and mindfulness. However, the quantitative analysis pointed to an inconclusive result due to moderate to high levels of heterogeneity among indicator of anxiety, depression, and mindfulness. Future work requires more studies to better elucidate the clinical significance of this possible association. The results suggest that MBCT is highly beneficial as an intervention for patients who have received treatment for breast cancer.

Insulin Resistance Indices and Carotid Intima-media Thickness in Physically Fit Adults: CHIEF Atherosclerosis Study.

AIMS: This study aims to examine the associations between various non-insulin-based insulin resistance (nIIR) indices and subclinical atherosclerosis assessed by carotid intima-media thickness (cIMT) in young adults. BACKGROUND: nIIR indices, e.g., serum triglycerides (TG) have been reported with an association with cIMT in middle- and old-aged adults. OBJECTIVE: We examined the associations of various well-known nIIR indices reported before with cIMT in young adults. METHODS: A total of 1,822 young adults free of diabetes in Taiwan were included in 2018-2020. nIIR indices were assessed by TG concentrations, the TyG index, defined as Ln (TG *fasting glucose/2), the TG/high-density lipoprotein cholesterol (HDL-C) ratio, defined as TG divided by HDL-C, and the metabolic score for IR (METS-IR), defined as Ln[(2*fasting glucose)+TG) * body mass index (BMI)/(Ln(HDL-C))]. Multivariable linear regression analyses with adjustments for age, sex, anthropometrics, smoking, alcohol consumption, blood pressure, and total cholesterol were used to determine the associations. For TG only, HDL-C and fasting glucose were additionally adjusted. RESULTS: In the overall participants, there was an association between cIMT and TG (ß: 0.057, p = 0.04). In subgroup analyses, cIMT was associated with TG (ß: 0.127, p = 0.004), the TyG index (ß: 0.119, p = 0.01), and TG/HDL-C (ß: 0.081, p = 0.03) in the overweight / obese (BMI ≥25 kg/m2), while not in the normal weight individuals. However, cIMT was correlated with TG (ß: 0.086, p = 0.01) and TG/HDL-C (ß: 0.077, p = 0.01) in those without hyperuricemia, while not in those with hyperuricemia. No association between the METS-IR and cIMT in any young adult subgroups was observed. CONCLUSION: This study highlights that some nIIR indices could be used to assess cIMT in young adults, particularly for those with obesity and those without hyperuricemia. The TG-based indices instead of the novel marker, METS-IR, are suggestive as stronger predictors of greater cIMT in young adults.

Electrocardiographic and echocardiographic predictors of greater carotid intima-media thickness in tactical athletes: The CHIEF atherosclerosis study.

OBJECTIVE: Both electrocardiographic and echocardiographic left ventricular hypertrophy (LVH) have been reported with an association with greater carotid intima-media thickness (cIMT), a marker of subclinical atherosclerosis in patients with hypertension, while the associations are unclear in physically fit young adults. METHODS: A total of 1822 Taiwanese military personnel, aged 18-40 years, received an annual health examination including electrocardiography (ECG) and echocardiography in 2018-2020. Left carotid bulb cIMT was measured by high-resolution ultrasonography. Multiple logistic regression analysis with adjustments for age, sex, smoking, alcohol consumption, body mass index, mean blood pressure, and physical fitness was used to determine the associations between echocardiographic and ECG parameters and the highest quintile of cIMT (≥0.8 mm). RESULTS: Cornell-based LVH, Myers et al.-based RVH and heart rate ≥75/min were associated with cIMT ≥0.8 mm [odds ratios (ORs) and 95% confidence intervals: 1.54 (1.01, 2.35), 1.66 (1.18, 2.33), and 1.39 (1.06, 1.83), respectively], while echocardiographic LVH defined as ≥46.0 g/m2.7 for men and ≥38.0 g/m2.7 for women was inversely associated with cIMT ≥0.8 mm [OR: 0.45 (0.24, 0.86)]. CONCLUSION: In tactical athletes of military, the associations of ECG and echocardiographic LVH with cIMT were in opposite directions. Higher physical fitness may cause cardiac muscle hypertrophy and reduce the atherosclerosis severity, possibly leading to the paradoxical echocardiographic finding. This study suggests that ECG-based LVH remains a good marker of subclinical atherosclerosis in our military population.

Non-Insulin-Based Insulin Resistance Indices and Localized Periodontitis in Physically Active Young Male Adults: CHIEF Oral Health Study.

AIMS: This study aims to examine the association between non-insulin-based insulin resistance indices and periodontitis severity in young males. BACKGROUND: Periodontitis has been reported with an association with insulin resistance in middle- and old-aged adults. OBJECTIVE: The association between insulin resistance and localized periodontitis in young adults is unclear. METHODS: A total of non-diabetic 1,111 military males in Taiwan were included in this study. Localized periodontitis was classified as healthy (N =665), stage I (N =130), stage II (N =161), and stage III (N =155) based on the world workshop in 2017. Insulin resistance was assessed by serum triglycerides concentrations, the triglycerides glucose (TyG) index, the product of serum triglycerides and fasting glucose, and the ratio of serum triglycerides to high-density lipoprotein cholesterol (TG/HDL-C). Multiple logistic regression analysis with adjustment for age, tobacco smoking, alcohol intake, abdominal obesity, and hypertension was used to determine the associations. RESULTS: Serum TG concentrations, TyG index, and TG/HDL-C ratio were dose-dependently associated with a greater risk of localized periodontitis severity (from stage I to stage III) [odds ratios and 95% confidence intervals: 1.001 (0.999-1.004), 1.003 (1.001-1.004) and 1.003 (1.002- 1.005) for TG; 1.45 (1.03-2.03), 1.65 (1.22-2.22) and 1.66 (1.22-2.26) for TyG index; 1.06 (0.99- 1.14), 1.09 (1.03-1.15) and 1.10 (1.04-1.16) for TG/HDL-C ratio]. However, the association was only found in obese individuals and those free of impaired fasting glucose. CONCLUSION: The present study confirmed that periodontitis may lead to insulin resistance in young male adults, particularly for those with obesity and without hyperglycemia. The TyG index is suggestive as the strongest indicator for the association between insulin resistance and periodontitis in young adults.

The Experience of Mindfulness-Based Stress Reduction on Menopausal Symptoms, Sleep Disturbance, and Body Image among Patients with Breast Cancer-A Qualitative Study.

BACKGROUND AND AIM: The objective was to decrease patient menopausal symptoms, sleep disturbance, and body image using a nonpharmacological therapy for cultivating key healthy lifestyle habits in patients with breast cancer. MATERIALS AND METHODS: The participants were 26 women with breast cancer who had recently received structured mindfulness-based stress reduction (MBSR) training in a clinical trial. Focus groups and interviews were conducted, during which the participants were asked semistructured, open-ended questions regarding the experiences of MBSR. RESULTS: The participants indicated that MBSR helped them to alleviate hot flashes and night sweats, and improve sleep quality and be more at ease with the external aspect of their body. On the other hand, during MBSR intervention in a group manner, the participants felt more psychological support and an outlet for sharing negative emotional experiences. CONCLUSION: This study identified the short-term benefits associated with group-based MBSR for women with breast cancer. In addition, our research identified the difficulties of intervention measures and coping methods. The study described the benefits of MBSR for patients with breast cancer. The findings of this study will help nursing staff identify the main coping menopausal symptoms and control negative mental health.

Hepatic and Systemic Inflammation for Left Ventricular Mass in Physically Fit Adults: CHIEF Heart Study.

BACKGROUND: Both low-grade systemic and hepatic inflammation could result in increased left ventricular mass (LVM) in the general population. However, the associations, which might be modified by exercise, have not been clarified in physically active young adults. METHODS: The study included 2,004 military males aged 18-43 years in eastern Taiwan. Systemic and hepatic inflammation was defined by the upper tertiles of blood white blood cell (WBC) counts (7.51-11.00 x 103/µL) and serum alanine aminotransferase (ALT: 30-120 U/L), respectively. LVM indexed for the body height ≥49 g/m2.7 was defined as left ventricular hypertrophy (LVH) based on echocardiography. Multiple logistic regression analysis adjusting for age, smoking, alcohol intake, physical fitness, and metabolic syndrome was utilized to determine the associations. RESULTS: As compared to the lower WBC/lower ALT group, there tended to have an increased risk of LVH with the higher WBC/lower ALT group, the lower WBC/higher ALT group, and the higher WBC/higher ALT group [odds ratios: 0.89 (95% confidence intervals (CI): 0.41-1.94), 1.90 (95% CI: 0.86-4.22) and 2.48 (95% CI: 1.04-5.92); p-value for trend = 0.01]. CONCLUSION: Our study suggested that in physically active males, those with hepatic inflammation rather than low-grade systemic inflammation had a higher risk of LVH. Hepatic injury might be relevant to LVH as an early sign of end-organ damage regardless of physical fitness in young adults.

Associations of decayed teeth and localized periodontitis with mental stress in young adults: CHIEF oral health study.

The associations of mental stress with decayed teeth in children and periodontitis in old-aged adults have been described. However, the associations for young adults were not clear. This study aimed to examine the associations of decayed teeth and localized periodontitis with mental stress in young adults. This study included 334 military recruiters, aged 19-45 years in Taiwan. Mental stress was assessed by the brief symptom rating scale-5 (BSRS-5), including five domains: anxiety, depression, hostility, interpersonal sensitivity and insomnia (maximum score of 20). Those with symptomatic mental stress were defined as having BSRS-5 > 5 (n = 34). Multiple linear and logistic regression models were used to determine the associations of decayed tooth numbers and periodontitis with BSRS-5, with adjustments for age, sex, education level, physical activity, body weight category and smoking status. The BSRS-5 was positively correlated with decayed tooth numbers [ß: 0.26 (95% confidence interval: 0.01-0.52)]. Those who had more than two decayed teeth [odds ratio: 3.59 (1.52-8.46)] had a higher risk of symptomatic mental stress. In contrast, the correlation between BSRS-5 and localized severer periodontitis was null. Our study recommended that decayed teeth instead of localized periodontitis, was a risk factor for mental stress in young adults.

Localized periodontitis and kidney function for the risk of proteinuria in young adults in the CHIEF oral health study.

This study aimed to investigate the association of localized periodontitis with proteinuria in 1281 military young adults in Taiwan. Localized periodontitis was classified as Healthy/Stage I (N = 928) or Stage II/III (N = 353). Stage 2 chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate (eGFR) of 60-89 mL/min/1.73 m2. Proteinuria was defined as protein levels of 2+ or 3+ on the dipstick test. Multiple logistic regression analysis with adjustments for age, sex, body mass index, remaining teeth number and other potential covariates were used to determine the association between localized Stage II/III periodontitis and dipstick proteinuria in patients with and without CKD. Localized stage II/III periodontitis was associated with a higher risk of dipstick proteinuria [odds ratio (OR) and 95% confidence interval: 1.89 (1.04-3.42)], but not with stage 2 CKD. However, the association between localized stage II/III periodontitis and dipstick proteinuria was observed only in patients with stage 2 CKD [OR: 3.80 (1.56-9.27)], while the association was null in participants without stage 2 CKD [OR: 1.02 (0.42-2.45)]. Our findings suggest that among young adults, especially those with a mildly impaired eGFR, localized periodontitis might contribute to acute or chronic kidney injury, which manifests as proteinuria.

Secondhand tobacco smoke exposure, urine cotinine, and risk of incident atrial fibrillation: The multi-ethnic study of atherosclerosis.

BACKGROUND: Secondhand tobacco smoke (SHS) exposure may reduce heart rate variability and lead to atrial fibrillation (AF); however prior study findings have not been confirmed using objective measures for both SHS and AF events. METHODS: We prospectively examined the association between SHS exposure and incident AF in 5731 participants, ages of 45-84 years and free of known AF and other cardiovascular diseases (CVD) at baseline (2000-2002), who were followed through 2015 in the Multi-Ethnic Study of Atherosclerosis (MESA). SHS weekly exposure time was identified by self-report. Urine cotinine was collected in a cohort subset of 3237 current non-smoking cohort participants. AF events were identified using Medicare claims, hospital records, and 12­lead electrocardiographic findings. A multivariable Cox proportional hazards regression analysis was used with simultaneous adjustment for demographic factors, educational level, health insurance status, active smoking status, tobacco pack-years, traditional CVD risk factors, depressive symptoms and medications. RESULTS: During a median follow-up of 14.0 years, 856 and 452 AF events were identified in the overall and the cohort subset, respectively. No association of SHS exposure time or urine cotinine with incident AF was observed. However, a higher AF risk with greater urine cotinine (8.53-442.0 ng/mL) compared with lower urine cotinine (≤7.07 ng/mL) was observed in never smokers [hazard ratios (HR) and 95% confidence intervals: 1.60 (1.16, 2.19)], but not in former smokers [HR: 0.88 (0.63, 1.23)] (p-value for multiplicative interaction: 0.009 and for additive interaction: 0.017, respectively). CONCLUSION: Objectively measured greater SHS exposure expressed by urine cotinine might be associated with 1.6-fold higher risk of incident AF in never smokers.

Dental caries and periodontitis and the risk of myopia in young adults: CHIEF oral health study.

AIM: Oral health and ocular diseases may be associated with collagen defects and inflammation status. However, the results from prior studies are conflicting. The aim of this study was to explore the association of dental caries and periodontitis with myopia in young adults. MATERIALS AND METHODS: A total of 938 military personnel aged 19-39 years receiving both oral and eye examinations from 2018 through 2020 were included in this study in Taiwan. The severity of myopia was graded as no myopia (diopters > - 0.5, N = 459), low myopia (diopters: - 0.5 to -5.9, N = 225) and high myopia (diopters ≤ - 6.0, N = 254). A multiple logistic regression analysis with adjustments for age, body mass index, systolic blood pressure, smoking, alcohol consumption, missing teeth numbers, blood leucocyte counts, triglycerides, high-density lipoprotein, and uric acid were used to determine the associations of actively dental caries, filled teeth and stage II/III periodontitis with myopia. RESULTS: The presence of any actively dental caries was significantly associated with a higher risk of any myopia (low or high) (odds ratio [OR] and 95% confidence intervals [95% CI] 1.42 [1.04-1.94]), whereas there was no association for filled teeth. Moreover, the association for stage II/III periodontitis was only observed with high myopia (OR: 1.52 [1.07-2.15]) and was not observed with low myopia. CONCLUSIONS: Our findings suggest that only actively dental caries and a higher severity of periodontitis were associated with myopia among young adults, thus highlighting the dental inflammation status in the oral cavity as a potential link to ocular diseases.

Muscular Strength and Carotid Intima-Media Thickness in Physically Fit Young Adults: The CHIEF Atherosclerosis Study.

Background: Greater muscular strength (MusS) has been found to have an inverse association with subclinical atherosclerosis in children, as well as with mortality from cardiovascular diseases (CVDs) in middle-aged and elderly individuals. However, the association of the degree of MusS with atherosclerosis may differ by sex and has not been clarified in young adults. Methods and Results: A total of 1021 Taiwanese military personnel, aged 18−40 years, participated in annual health examinations in 2018−2020. MusS was separately assessed by 2-min push-up and 2-min sit-up numbers. Subclinical atherosclerosis was measured by the left carotid bulb intima−media thickness (cIMT) using high-resolution ultrasonography. Multiple linear regression with adjustments for age, sex, alcohol intake, cigarette smoking, anthropometric indices, blood pressure, and lipid profiles was utilized to determine the correlation between MusS and cIMT. Both 2-min push-up and 2-min sit-up numbers were inversely correlated with cIMT (standardized ß: −0.089 and −0.072, respectively; both p-values < 0.05). In men, both 2-min push-up and 2-min sit-up numbers were inversely correlated with cIMT (standardized ß: −0.076 and −0.086, respectively; both p-values < 0.05), while in women, 2-min push-up numbers but not 2-min sit-up numbers were inversely correlated with cIMT (standardized ß: −0.204 and −0.01; p = 0.03 and 0.99, respectively). Conclusions: Among young adults, there was an inverse association between MusS and cIMT, emphasizing the beneficial impact of MusS on the regression of atherosclerosis. The study also revealed a sex difference and suggested that training of the upper arm muscles may be an effective preventive measure for young women to reduce the risk of early cardiovascular diseases.

Erythrocyte indices and localized stage II/III periodontitis in military young men and women: CHIEF oral health study.

BACKGROUND: Prior studies have shown an association between generalized periodontitis and anemia in older or undernourished adults. The aim of the study was to examine the associations of erythrocyte indices with localized periodontitis in robust young adults, which has never been reported before. METHODS: The study included 1286 military participants, aged 19-40 years, with regular exercise training in Hualien, Taiwan. Localized periodontitis was grouped to healthy/stage I and stage II/III (n = 803 and 325) in men and (n = 130 and 28) in women according to the 2017 criteria of the world workshop. Systemic inflammation was evaluated by leukocyte counts. Multiple logistic regression analysis with adjustment for age, tobacco smoking status, betel nut chewing status, body mass index and leucocyte counts were used to determine the associations. RESULTS: Greater mean corpuscular volume in young men [odds ratio (OR) and 95% confidence intervals 1.03 (1.01-1.06)], and greater hematocrit and hemoglobin levels in young women were associated with a higher risk of localized stage II/III periodontitis [OR: 1.17 (1.02-1.34) and 1.60 (1.06-2.41), respectively]. However, there were no associations for erythrocyte counts. CONCLUSIONS: The localized stage II/III periodontitis risk increased with greater erythrocyte indices in robust young adults. This finding could be explained in part by that localized periodontitis may promote physical stress, possibly resulting in an increase of erythrocyte indices. On the other side, greater physical fitness associated with a lower risk of periodontitis may consume iron storage in the body, leading to exercise-induced anemia or smaller erythrocyte volume.

Cardiorespiratory Fitness and Carotid Intima-Media Thickness in Physically Active Young Adults: CHIEF Atherosclerosis Study.

Background: The relationship of cardiorespiratory fitness (CRF) with subclinical atherosclerosis affected by the body adiposity has been observed in children, whereas this relationship remains unclear in young adults. Methods and Results: A total of 1520 military recruits, aged 18−40 years, were included in Taiwan in 2018−2020. All subjects underwent detailed physical and blood laboratory examinations. CRF was evaluated by time for a 3000 m run, and subclinical atherosclerosis was evaluated by intima−media thickness of the bulb of the left common carotid artery (cIMT) utilizing high-resolution ultrasonography. Multivariable linear regression analysis with adjustments for age, sex, cigarette smoking, alcohol intake, systolic and diastolic blood pressure, high- and low-density lipoprotein cholesterols, fasting glucose, waist circumference, serum uric acid and serum triglycerides were utilized to determine the correlation between CRF and cIMT. CRF was independently correlated with cIMT (standardized ß: 0.11, p < 0.001). Of the cardiometabolic risk markers, serum triglycerides were the only independent risk marker of cIMT (standardized ß: 0.063, p = 0.03). In addition, the association of CRF with cIMT did not differ between those with a body mass index (BMI) ≥ 25 kg/m2 and those with BMI < 25 kg/m2 (standardized ß: 0.103 and 0.117; p = 0.01 and 0.005, respectively). Conclusions: In physically active young men and women, there was an inverse association of cIMT with CRF, which was observed in both overweight/mild obesity and normal-weight individuals, highlighting the importance of endurance capacity on reducing risk of early atherosclerosis and implying that the moderation effect of body adiposity might not be present in this population.

Associations of decayed and filled teeth with localized stage II/III periodontitis in young adults: The CHIEF oral health study.

Background/purpose: To investigate the associations between treated and untreated dental caries and periodontitis in young adults. Materials and methods: The study enrolled 1289 participants aged 18-45 years in Taiwan. Localized periodontitis was categorized into healthy and stage II/III (n = 936 and n = 353, respectively) based on the 2017 criteria of the World Workshop. Multivariable logistic regression analysis with adjustments for sex, age, tobacco smoking status, betel nut consumption status, metabolic syndrome, and total white blood cell count was used to determine the associations. Results: Decayed tooth numbers were positively associated with localized stage II/III periodontitis [odds ratio (OR): 1.15 (95% confidence intervals (CI): 1.06-2.25)], while filled tooth numbers were inversely associated with localized stage II/III periodontitis in young adults [OR: 0.96 (95% CI: 0.92-0.99)]. Conclusion: Our study confirms the relationship between dental caries and periodontitis by direct evidence that the more decayed teeth there are, the higher the risk of periodontitis and by indirect evidence that the more treated decayed teeth there are, the lower the risk of periodontitis in young adults.

Impact of mindfulness-based stress reduction on female sexual function and mental health in patients with breast cancer.

PURPOSE: There have been few studies using mindfulness-based stress reduction (MBSR) to improve sexual function in Asian women with breast cancer. This study aimed to evaluate the impact of mindfulness intervention on female sexual function, mental health, and quality of life in patients with breast cancer. METHODS: Fifty-one women with breast cancer were allocated into 6-week MBSR (n=26) sessions or usual care (n=25), without differences in group characteristics. The research tools included the Female Sexual Function Index (FSFI), the Depression Anxiety Stress Scales-21 (DASS-21), and the EuroQol instrument (EQ-5D). The Greene Climacteric Scale (GCS) was used to verify the foregoing scale. The effects of MBSR were evaluated by the differences between the post- and pre-intervention scores in each scale. Statistical analyses consisted of the descriptive dataset and Mann-Whitney ranked-pairs test. RESULTS: Although MBSR did not significantly improve sexual desire and depression in patients with breast cancer, MBSR could improve parts of female sexual function [i.e., Δarousal: 5.73 vs. -5.96, Δlubrication: 3.35 vs. -3.48, and Δsatisfaction: 8.48 vs. 1.76; all p <.005], with a range from small to medium effect sizes. A significantly benefits were found on mental health [Δanxiety: -10.92 vs.11.36 and Δstress: -10.96 vs.11.40; both p <.001], with large effect sizes, ranging from 0.75 to 0.87. CONCLUSION: Our study revealed that MBSR can improve female sexual function and mental health except for sexual desire and depression in women with breast cancer. Medical staff can incorporate MBSR into clinical health education for patients with breast cancer to promote their overall quality of life.

Association of hepatic and systemic inflammation with localized stage II/III periodontitis in young males: The CHIEF oral health study.

AIM: To clarify the association between systemic and hepatic inflammation and localized periodontitis which has been reported to vary among races. MATERIALS AND METHODS: The study included 1112 military males, aged 18-40 years, in Taiwan. Participants were classified as periodontally healthy/stage I (n = 796) or stage II/III periodontitis (n = 316), according to the 2017 world workshop criteria. Systemic and hepatic inflammation were defined by the highest tertiles of blood leukocyte counts (7.51 × 103 /µl) and alanine aminotransferase (30 U/L), respectively. Multiple logistic regression analysis with adjustments for age, metabolic syndrome, betel nut consumption and smoking was carried out. RESULTS: There was a significant association between high systemic inflammation, irrespective of hepatic inflammation severity, and localized stage II/III periodontitis (odds ratio [OR], 1.62 [1.09-2.42] and 1.47 [1.00-2.15], respectively, in the presence of high or no hepatic inflammation. However, no significant association was found among participants with low systemic inflammation, irrespective of the severity of hepatic inflammation (OR, 1.31 [0.91-1.91]). CONCLUSIONS: An association between hepatic inflammation and localized periodontitis in Taiwanese was observed only if systemic inflammation coexisted, possibly accounting for the reported differences in the association between Japanese and non-Asian populations in prior studies.
