Abstract
OBJECTIVES Experimental and acute exposure studies imply that manganese affects red blood cell production. Nevertheless, the association between environmental exposure and red blood cell distribution width (RDW) has yet to be explored. This research sought to assess the correlation between blood manganese levels and RDW within the general population of the United States. MATERIALS AND METHODS Employing weighted multiple linear regression models, data from the 2011-2018 National Health and Nutrition Examination Survey (NHANES) were utilized to assess the correlation between manganese levels in the blood and RDW. Restricted cubic spline plots and two-piecewise linear regression models were also employed. RESULT The analysis included a total of 15882 participants in which we determined an independent positive relationship between blood manganese levels and RDW among participants(β = 0.079, P<0.001). Moreover, we identified a J-shaped association between blood manganese levels and RDW in total participants (inflection point for blood manganese: 7.32 ug/L) and distinct subgroups following adjusted covariates. Women exhibited a more pronounced association, even after controlling for adjusted covariates. CONCLUSIONS We determined a J-shaped relationship between blood manganese levels and RDW with an inflection point at 7.32 ug/L for blood manganese. Nevertheless, fundamental research and large sample prospective studies are needed to determine the extent to which blood manganese levels correlate with RDW.

[PMID: 38975361 PMCID: PMC11224452 DOI: 10.3389/fpubh.2024.1404407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 06/04/2024] [Indexed: 07/09/2024] Open
Abstract
Objectives Depression is largely preventable, and strategies that can effectively suppress its development are imperative. We aimed to examine whether physical activity and sedentary behavior were associated with depression and explore the possible mediatory role of complete blood count in this association. Methods In this cross-sectional study, data were integrated from the National Health and Nutrition Examination Study (2007-2018). Depression was defined using the Patient Health Questionnaire-9. The risk for depression, expressed as odds ratio (OR) and 95% confidence interval (CI), was quantified by survey-weighted logistic regression analyses. Results A total of 31,204 respondents were analyzed. Significance was identified for all, except walking or bicycling per week, types of physical activity, and sedentary behavior. Per 1 standard deviation (SD) increment in metabolic equivalent of task (MET) of weekly vigorous recreational physical activity was associated with 31.3% decreased depression risk (adjusted OR: 0.687, 95% CI: 0.5663-0.840). Per 1 SD increment in sitting time can increase depression risk by 22.4% (adjusted OR: 1.224, 95% CI: 1.131-1.325). In subsidiary analyses, the association with depression was reinforced in respondents aged ≤65 years and those overweight or obese. Mediation analyses revealed significant effects for red blood cell (RBC) on total MET (19.4%) and moderate work-related physical activity (MWPA) (22.0%), and for red cell distribution wide (RCDW) on vigorous work-related physical activity (17.7%), moderate work-related physical activity (13.1%), total MET (11.2%), and sitting time (16.4%) (p < 0.01). Conclusion Our findings indicate that more physical activity and less sitting time were associated with a lower likelihood of having depression among US adults, and this association was probably mediated by RBC and RCDW.

Abstract
BACKGROUND Regular exercise elicits adaptive changes in several organs and physiological processes, including erythrocyte properties. METHODS In a group of 79 subjects (62 men and 17 women; mean age 31.37 ± 10.19 years) who trained several times a week as they practiced amateur sports, we evaluated the elongation index, markers of erythrocyte deformability, red blood cell distribution width (RDW), indicators of erythrocyte anisocytosis, hematocrit, hemoglobin, and the main erythrocyte indices (MCV, MCH, MCHC) in basal conditions. RESULTS In comparison with a group of healthy, but not training, volunteers, the values of the elongation index, and not the RDW, are increased, and this datum is accompanied by an increase in MCV and MCHC, likely related to an increased presence of circulating young erythrocytes in training subjects. We also divided the same group according to the median of the VO2max, observing that the subgroup above the median shows both an increase in the elongation index values and a decrease in MCH and MCHC. CONCLUSIONS In trained subjects, there is no correlation between the values of the elongation index and the RDW, while the interrelations among the elongation index, RDW, and main erythrocyte indices appear to be of particular interest and of a certain complexity.

Gender Differences in Physical Activity Engagement Among Adolescents With Congenital Heart Disease. J Pediatr Psychol 2021; 47:859-869. [PMID: 34725688 DOI: 10.1093/jpepsy/jsab114] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 09/28/2021] [Accepted: 10/10/2021] [Indexed: 11/12/2022] Open
Abstract
OBJECTIVE The current study aimed to (a) describe moderate-to-vigorous physical activity (MVPA), sedentary behavior (SB), and cardiorespiratory fitness (VO2Peak) via objective assessment among adolescents with congenital heart disease (CHD), (b) examine gender differences on MVPA, SB, VO2Peak, and the Theory of Planned Behavior elements, and (c) identify whether gender moderates the relationships between the Theory of Planned Behavior elements and MVPA, SB, and VO2Peak. METHODS Adolescent CHD survivors (N = 86; ages 15-18 years) wore an accelerometer to assess MVPA and SB, underwent an exercise stress test to assess VO2Peak, and completed a survey of the Theory of Planned Behavior elements as measured by perceived benefits (attitudes), family/friend support and perceived norms (social norms), and self-efficacy and barriers (perceived behavioral control) to engaging in physical activity. RESULTS On average, CHD survivors engaged in 22.3 min (SD = 15.3) of MVPA/day and 9 hr of SB/day (M = 565.8, SD = 102.5 min). Females engaged in less MVPA but not more SB had a lower mean VO2Peak, reported lower self-efficacy, and perceived greater barriers than males. In a regression model, barriers explained unique variance in MVPA and VO2Peak, but the relationship between barriers and MVPA/VO2Peak did not vary by gender. Self-efficacy did not explain unique variance in MVPA and VO2Peak when included in a model with gender and barriers. CONCLUSIONS Family/friend support for physical activity engagement may be an important consideration when developing physical activity interventions for adolescent CHD survivors. The role of gender differences in self-efficacy and perceived barriers on physical activity engagement warrants further investigation.

Red cell distribution width: a new tool for the severity prediction of sleep apnoea syndrome in children. ERJ Open Res 2020; 6:00278-2019. [PMID: 33043053 PMCID: PMC7533379 DOI: 10.1183/23120541.00278-2019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Accepted: 06/10/2020] [Indexed: 12/04/2022] Open
Abstract
Introduction Red cell distribution width (RDW) is a parameter included in the complete blood count which informs about the size of the circulating red blood cell population and its distribution. In adults, an increase in RDW was shown to be associated both with obstructive sleep apnoea (OSA) and with an increase in cardiovascular mortality. The aim of this study was to determine whether RDW is a potential biomarker for screening children with moderate–severe OSA. Methods An observational study in snoring patients was performed. All patients underwent a sleep study and were classified either as simple snorers (apnoea–hypopnoea index (AHI) <1 event·h−1) or as patients with OSA (mild AHI ≥1 to <5 events·h−1; moderate–severe AHI ≥5 events·h−1). Blood analyses (complete blood count and C-reactive protein) were performed for every individual. Results A total of 175 individuals were recruited. The mean age was 8.3±3.6 years. Correlation studies between RDW and several sleep-related parameters showed negative significant associations with minimum oxygen saturation, and positive significant associations with oxygen desaturation index (≥3% and ≥4%), AHI and the arousal index. A predictive model for paediatric severe OSA (AHI ≥5 events·h−1) was found based on mean corpuscular haemoglobin concentration (MCHC) <34.9 g·dL−1 and RDW >13.1% values, adjusting for body mass index z-score and age (area under the curve 0.657; p=0.004). In addition, differences were found in eosinophil count and C-reactive protein concentrations among the three subgroups. Conclusions In children, RDW stands out as a biomarker associated with the severity of OSA. The use of RDW and MCHC could be a simple but useful tool for the severity prediction of paediatric OSA in snoring patients. Red cell distribution width and mean corpuscular haemoglobin concentration are blood markers associated with the severity of paediatric OSAhttps://bit.ly/2Asw1xa

Abstract
Lower levels of physical activity (PA) have been associated with increased risk of cardiovascular disease. Worldwide, there is a shift towards a lifestyle with less PA, posing a serious threat to public health. One of the suggested mechanisms behind the association between PA and disease development is through systemic inflammation, in which circulating blood cells play a pivotal role. In this study we investigated the relationship between genetically determined PA and circulating blood cells. We used 68 single nucleotide polymorphisms associated with objectively measured PA levels to perform a Mendelian randomization analysis on circulating blood cells in 222,645 participants of the UK Biobank. For inverse variance fixed effects Mendelian randomization analyses, p < 1.85 × 10−3 (Bonferroni-adjusted p-value of 0.05/27 tests) was considered statistically significant. Genetically determined increased PA was associated with decreased lymphocytes (β = –0.03, SE = 0.008, p = 1.35 × 10−3) and decreased eosinophils (β = –0.008, SE = 0.002, p = 1.36 × 10−3). Although further mechanistic studies are warranted, these findings suggest increased physical activity is associated with an improved inflammatory state with fewer lymphocytes and eosinophils.

Abstract
Objective: Individuals with rheumatoid arthritis (RA) have increased risk of cardiovascular disease (CVD). Lifestyle factors such as prolonged sedentary behavior (SB) and reduced physical activity (PA) may heighten the risk of CVD. The objective of the study was to investigate the role of SB and PA as predictors for long-term CVD risk in RA patients.Methods: A subsample of 273 people diagnosed with RA was extracted from the 2003-2006 National Health and Nutrition Examination Survey and included in this cross-sectional study. Valid accelerometry data were categorized into sedentary behavior, very light, light, and moderate-to-vigorous physical activity. Functional limitations were assessed using a physical function questionnaire. The Framingham risk score (FRS) was used to calculate 10-year CVD risk. Regression models were used to examine the relationships between SB, PA, and 10-year CVD risk while controlling for potential confounders.Results: Participants spent an average of 9 h/day sedentary, 4 h in very light PA, 1 h in light PA, and 0.4 h in moderate-to-vigorous PA. Greater sedentary time was associated with higher 10-year CVD risk (p= 0.019). Increased daily PA, at all intensities, was inversely associated with 10-year CVD risk (p< 0.01). In the fully adjusted regression model, associations between 10-year CVD risk and SB (β = 0.31, R2 = 0.27, p< 0.01), very light PA (β = -0.19, R2 = 0.26, p< 0.01), light PA (β = -0.16, R2 = 0.25, p< 0.01), and moderate-to-vigorous PA (β = -0.15, R2 = 0.25, p< 0.01) remained significant.Conclusions: Strategies for decreasing SB and increasing PA should be explored with individuals with RA in order to decrease long-term CVD risk.
