A Systematic Review of the Association Between Muscular Fitness and Telomere Length Across the Adult Lifespan

This study aimed to systematically review the association between telomere length (TL) and muscular fitness. In October 2020, an articles search was applied to PubMed, Scopus, and Web of Science. Eligibility criteria included: cross-sectional, prospective, and experimental study design; outcomes included TL; results expressed the relationship between muscular fitness and TL; studies published in English, Portuguese, or Spanish. Nine studies were included in the review. Results from the four prospective studies are mixed. In one study, the changes in TL were associated with grip strength. Another study concluded that longer mid-life TL was associated with increased grip strength later in life. However, in the other two studies, the association between TL and sarcopenia was not strong. Nevertheless, longer TL was associated with a slower decline in grip strength in older people. From the four cross-sectional studies, three indicated that TL was associated with muscular fitness. On the other hand, in a study with powerlifters, TL remained within the range of values found in subjects with no history of regular strength training, supporting the notion that muscular fitness was not associated with TL. The cross-sectional and prospective studies showed that the relationship between TL and muscular fitness is not conclusive. It seems that there is a positive association between TL and muscular fitness in middle-aged and older adults. However, among younger adults, this relationship was not observed.

The Relationship

The relationship between serum dehydroepiandrosterone sulphate (DHEA-S) and anti-Mullerian hormone (AMH) levels has not been fully established. Therefore, we performed a large-scale cross-sectional study to investigate the association between serum DHEA-S and AMH levels. The study included a total of 2155 infertile women aged 20 to 46 years who were divided into four quartile groups (Q1 to Q4) based on serum DHEA-S levels. We found that there was a weak positive association between serum DHEA-S and AMH levels in infertile women (r = 0.190, p < 0.001). After adjusting for potential confounders, serum DHEA-S levels positively correlated with serum AMH levels in infertile women (β = 0.103, p < 0.001). Infertile women in the highest DHEA-S quartile category (Q4) showed significantly higher serum AMH levels (p < 0.001) compared with women in the lowest DHEA-S quartile category (Q1). The serum AMH levels significantly increased across increasing DHEA-S quartile categories in infertile women (p = 0.014) using generalized linear models after adjustment for potential confounders. Our data show that serum DHEA-S levels are positively associated with serum AMH levels.

The Relationship

Bicultural identity orientations have rarely been examined in relation to both perceived discrimination and psychological distress. Furthermore, these constructs have usually been studied in isolation, but their intersection is essential for understanding intercultural relations in multicultural societies. Using cross-sectional data from 1,143 Canadian undergraduate students from immigrant families, this study explored the relationship between perceived discrimination and psychological distress, and how bicultural identity orientations might mediate this relationship. The structural equation modeling results indicated that perceived discrimination was associated with higher levels of psychological distress and hybrid, monocultural, alternating, and conflicted orientations, but lower levels of complementary orientation. Alternating and conflicted orientations were related to higher psychological distress, whereas the other orientations were not. Alternating and conflicted orientations mediated the relationship between perceived discrimination and psychological distress, whereas the other orientations did not. The findings are discussed in light of theories on identity integration, rejection–identification, and acculturation.

Introduction: Reduced tongue pressure is one of the causes of dysphagia. The purpose of this study was to investigate the relationship between dental findings and tongue pressure, and whether prosthetic treatment prevents reduced tongue pressure. Methods: This was a cross-sectional study. Participants were 745 community-dwelling adults and elderly persons in the Goto Islands in Nagasaki, who underwent a health checkup for residents in 2015 and 2016. Data were collected on gender; age; grip strength; hemoglobin; Creatinine (Cr); glycated hemoglobin (HbA1c); history of stroke; smoking, drinking, exercise, and walking habits; number of teeth; wearing of removable dentures; functional units of natural teeth (n-FTUs), fixed prostheses (nif-FTUs), and removable dentures (t-FTUs); and tongue pressure. The associations between each variable and tongue pressure were examined using multiple regression analysis. Next, those with 3 or fewer n-FTUs were selected, and differences in tongue pressure were compared between those with 3 or fewer nif-FTUs and those with 4 or more nif-FTUs, using a propensity score matching method. Results: Male gender, weak grip strength, low HbA1c, no drinking, and a low number of teeth were independent factors significantly associated with lower tongue pressure. Among participants with 3 or fewer n-FTUs, the 43 with 4 or more nif-FTUs showed significantly higher tongue pressure than the 43 with 3 or fewer nif-FTUs after propensity score matching, although the number of t-FTUs was not associated with tongue pressure. Discussion/Conclusion: Tooth loss was significantly associated with lower tongue pressure. It was suggested that fixed prosthesis treatment might prevent the reduction of tongue pressure, but removable dentures did not have such an effect.

Outcomes included students’ school grade or a standardised test or measure of academic achievement. Explanatory variables were cardiorespiratory fitness and objective and self-reported physical activity. Inclusion criteria included school-aged children and adolescents aged–18 years (or students from primary to secondary school when student’s participants age was not described) and articles published in English, Portuguese or Spanish.ResultsA total of 51 articles met inclusion criteria: 41 cross-sectional, 2 intervention and 8 longitudinal studies. Results from 11 studies were inconsistent regarding the relationship between objectively measured physical activity and academic achievement. Ten of the 16 articles reported positive associations between self-reported physical activity and academic achievement. From the 22 studies that analysed the relationship between cardiorespiratory fitness and academic achievement, it was verified that they all generally support the beneficial effect of cardiorespiratory fitness on students’ academic achievement.ConclusionHigher cardiorespiratory fitness may be important to enhance children and adolescents’ health and, additionally, academic achievement. Due to a lack of consensus across studies, methodological issues associated with the assessment of physical activity should be considered when investigating physical activity and academic achievement.

The Relationship

The COVID-19 pandemic has created more occupational stressors, particularly work–family interface issues. The purpose of this study was to investigate the moderating role of occupational stressors in the relationship between a personal resource (psychological capital) and family satisfaction. A cross-sectional study was carried out with a sample of 787 employees (367 males, 420 females) from the Greater Bay Area of China between October and November 2020. Participants completed an online survey which included the Chinese version of the Psychological Capital Questionnaire, measures of occupational stressors from the Work Stress Management DIY Kit and a measure of family satisfaction. Latent moderated structural equation modeling revealed that family satisfaction was positively associated with psychological capital and negatively associated with occupational stressors. Furthermore, occupational stressors weakened the positive association between psychological capital and family satisfaction. These findings provided empirical evidence for the work–home resources model and may suggest that it would be beneficial to boost psychological capital and reduce occupational stressors of employees.

Nature Experience

History is replete with examples where humans have sought refuge in nature for psychological restoration. In this cross-sectional study we explore the relationship of nature experience and mindfulness. Nature experience is assessed through “nature in the neighbourhood”, “frequency of visit” to nature-rich spaces, as well as one's inherent connection with nature described as “nature relatedness”. The study sample consisted of 334 Indian adults. The findings from this study show that frequency of visit to nature-rich spaces has a significant positive association with mindfulness. The hierarchical regression analysis suggests an interaction effect of “nature relatedness” in the association of the presence of nature rich spaces in the neighbourhood, frequency of visit as well as mindfulness. Interestingly, when childhood experiences were explored they had a significant association with “nature relatedness” and mindfulness. The evidence from this research suggests that nature experience may find its application as one of the mindfulness techniques prescribed for self-management of mental health problems.

Low K

Introduction: Recently, the balance between sodium and potassium intake, i.e. sodium-to-potassium (Na/K) ratio, has received significant attention for prevention of hypertension. Previous studies reported the positive association between urinary Na/K (uNa/K) ratio and hypertension. However, even the same uNa/K ratio value, there might be high Na/ high K ratio or low Na/ low K ratio. Hypothesis: We assessed the hypothesis that blood pressure (BP) is higher in high Na/ high K group than that in low Na/ low K group even at the same uNa/K ratio in general population in cross-sectional study. Methods: The subjects were 20 to 74 years old who participated in The Tohoku Medical Megabank Project Community-based Cohort Study. Of these participants, we targeted 54,011 subjects (men: 20,505 women: 33,506 mean age: 59.9 years) who had information of BP, urinary Na and K. We estimated 24-h urinary excretion of Na and K using Tanaka formula. Urinary Na and K were each classified into quartiles (Na; Q1~Q4, K; Q1~Q4), and set all 16 groups of uNa/K ratio by combining Na and K respectively. To assess the relationship between casual uNa/K ratio and BP, we performed an analysis of covariance to calculate the adjusted mean systolic BP (SBP). We included covariate factors as age, sex, BMI and alcohol intake. We also assessed the relationship between uNa/K ratio and SBP using multiple regression analyses adjusted for covariate factors. We stratified the participants into two groups: ‘under treatment for hypertension’ (n=17,091) and ‘without treatment for hypertension (n=36,920)’. Results: The mean of uNa/K ratio for each group of Na (Q1)/K(Q1), Na (Q2)/K(Q2), Na (Q3)/K(Q3) and Na (Q4)/K(Q4) was all 4.0. As previous report showed, higher uNa/K ratio group showed higher SBP and lower uNa/K group showed lower BP. When we compared adjusted mean SBP of Na (Q1)/K(Q1) and Na (Q4)/K(Q4) the value were comparable, but the value were significantly higher in Na (Q4)/K(Q4) group (The adjusted mean SBP of Na (Q1)/K(Q1), Na (Q2)/K(Q2), Na (Q3)/K(Q3) and Na (Q4)/K(Q4) was 123.6, 124.9, 124.7 and 125.5 mmHg, respectively). The uNa/K was significantly positively associated with SBP independently of age, sex, BMI, and alcohol intake. The finding was unchanged the results in under treatment group. Conclusions: BP was significantly higher in high Na/ high K group than in low Na/ low K group even at the same uNa/K ratio. We suggested that not only increasing K intake but also reducing salt is important for preventing hypertension.

The Relationship

Background: Chronic kidney disease (CKD) strongly predicts sudden cardiac death and may elevate the risk of certain cardiac arrhythmias like atrial fibrillation; however, the relationships between CKD and various types of arrhythmia are not well-characterized. Methods: We performed a systematic review and meta-analysis by searching Embase and PubMed for prospective, cross-sectional, and case-control studies examining the associations of two key CKD measures, estimated glomerular filtration rate (eGFR) and albuminuria, with arrhythmias in adults that were published until July 2018. We performed qualitative assessment of studies using the Newcastle Ottawa Quality Assessment Scale. We pooled the results using random-effects models. Results: Among 16,245 articles, we identified 34 prospective (n=24,213,233), 21 cross-sectional (n=253,328), and 4 case-control (n=1,694) studies that included diverse study populations from 19 countries and were mostly high quality. Most prospective studies examined the relationship between eGFR and atrial fibrillation (AF), and demonstrated that lower eGFR was associated with a higher risk of AF (pooled hazard ratio [HR] 1.72 [95% CI: 1.30, 2.27] comparing reduced vs. referent eGFR groups)[ Figure ]. A few studies examined albuminuria and demonstrated its associations with AF (pooled HR 2.16 [95% CI: 1.74, 2.67] comparing high vs. low albuminuria). Results were similar for cross-sectional studies. Four prospective studies reported a higher incidence of ventricular tachycardia resulting in ICD shock according to reduced eGFR (pooled HR 2.32 [95% CI: 1.74, 3.09] comparing reduced vs. referent eGFR groups). Limited number of studies examined other types of arrhythmia. Conclusion: We identified robust data on the relationship between CKD (eGFR and albuminuria) and AF. Reduced eGFR was associated with life-threatening ventricular arrhythmias. Our review highlights the need of future studies for non-AF arrhythmias, especially in the context of albuminuria.
