Greater physical activity levels are associated with lower prevalence of tumors and risk of cancer in Spanish population: A cross-sectional study.

Cancer is a leading cause of death worldwide and insufficient physical activity is a significant risk factor. This study analyzed the tumor prevalence based on sex, age, smoking, BMI, and physical activity level (PAL) in the Spanish people. Data from the Spanish National Health Survey (ENSE) was used, comprising a sample of 17,704 people diagnosed with malignant tumors. The findings revealed compelling associations (P < 0.001) between all variables examined and the prevalence of malignant tumors. Notably, women exhibited a higher prevalence than men (P < 0.05). Furthermore, individuals classified as obese displayed a greater prevalence of tumors than those within the normal weight range (P < 0.05). The analysis also showed that the inactive group had a higher prevalence of malignant tumors than the active group (P < 0.05). This study identified significant dependency relationships (P < 0.001) between PAL and the various population groups examined. Additionally, the general population analyzed in the ENSE2017 study demonstrated a reduced risk of developing malignant tumors among the active (P < 0.05) and very active groups (P < 0.05) compared to the inactive group. This risk reduction was consistently observed across different subgroups, including men, women, specific age groups, smoking, and BMI categories (P < 0.05). This study highlighted the importance of regular physical activity in reducing the risk and prevalence of malignant tumors in the Spanish population. These findings underscore the critical role of engaging in physical activity as a protective measure against cancer. Encouraging individuals to adopt an active lifestyle could significantly contribute to cancer prevention efforts and promote overall well-being.

Higher physical activity level and perceived social support is associated with less psychological distress in people with anxiety.

Introduction: Anxiety is one of the most prevalent mental illnesses in first world societies, generating discomfort in the people who suffer from it, and high expenses and economic losses in the society. The physical activity (PA) performed, together with the perceived social support (PSS) by people with anxiety could be related to the psychological distress of people with anxiety. Objectives: To study the relationships between mental health and its dimensions, through Golberg's General Health Questionnaire (GHQ12), and the level of PA (PAL) and the PSS in the Spanish adult population with anxiety. Hypothesis: A higher PAL, and a higher PSS, is related to a lower psychological distress in this population. Design and Methodology: This study included 1,661 adults with anxiety, residents in Spain. It was a cross-sectional study with data obtained from the Spanish National Health Survey. A Kolmogorov-Smirnov test was applied to examine the data distribution of the variables. The median and interquartile range were used to characterize the sample for continuous variables, and absolute and relative frequencies were used for categorical variables. The Mann-Whitney U test was used to examine the differences between sexes. Dependence between PAL and sex was studied using the chi-square statistic. A Krustal-Wallis test was used to evaluate the existence of differences in the baseline medians on the GHQ-12, according to PAL level. Finally, the correlations between mental health and its dimensions with PAL and the Duke-UNC-11 scores were analysed, obtaining Spearman's rho and Pearson's correlation coefficient. Results: Moderate inverse correlations were found between the GHQ-12 and: PAL (rho: -0.219); PSS (r: -0.347). PAL and PSS presented moderate inverse correlations with successful coping (rho: -0.206 and r: -0.325), self-esteem (rho: -0.222 and r: -0.333) and stress (rho: -0.158 and r: -0.288). Conclusions: Greater PAL and social support are associated with reduced psychological distress in people with anxiety.

Physical Activity and Emotional Regulation in Physical Education in Children Aged 12-14 Years and Its Relation with Practice Motives.

This study aimed to analyze the different types of emotional regulation in first and second year high school students according to sex and age. Many adolescents do not meet the minimum WHO recommendations, at a critical stage in which habits that will later be maintained are established. For this reason, physical education is an important means to promote these habits and an understanding of the reasons for their participation in physical education. For this purpose, PLOC-2 was used. The Kolmogorov-Smirnov test was used to determine the characteristics of the data, the ANOVA test to explore the differences between sexes, and the Spearman test for correlations between the type of regulation and age. The results showed significant differences in several items and emotional regulation by sex and an inverse correlation between age and demotivation. There are differences between the reasons why both sexes perform physical activity, and we have determined that boys have more intrinsic regulation than girls do.

Association between GHQ-12, Duke-UNC-11, Physical Activity, and Self-Perceived Health in Spanish Adults with Cancerous Tumours: A Cross-Sectional Study.

Background: In Spain, people who have overcome some type of cancer have significantly worse self-perceived health (SPH) and higher rates of depression than people who have never suffered any type of cancer. Objective: to explore the relationships among physical activity levels (PAL), perceived social support (PSS), and SPH in terms of mental health and its dimensions in Spanish adults with cancerous tumours. Methods: A correlational study rooted in the National Health Survey 2017 for adults was carried out, including 627 Spanish residents who reported having malignant tumours. Results: A dependent association was found between PAL and SPH (p < 0.001). The mental health mean score decreased as PAL increased for the total sample and for both sexes, separately (p < 0.001). Low reverse associations were also observed between PAL and mental health (rho: −0.274; p < 0.001), successful coping (rho: −0.239; p < 0.001) and self-confidence (rho: −0.264; p <0.001). Moreover, PSS weakly and inversely correlates with mental health (r: −0.225; p < 0.001), successful coping (r: −0.218; p < 0.001) and self-confidence (r: −0.231; p < 0.001). A binary logistic model showed that active and very active people presented less threat of poor SPH, as did people with higher PSS (p < 0.001). Conclusions: Greater levels of physical activity are associated with larger mean scores in the three dimensions of mental health, perceived social support and self-perceived health in people with cancerous tumours.

Physical Activity Reduces the Risk of Developing Diabetes and Diabetes Medication Use.

Diabetes is a global public health challenge, exerting a large socioeconomic burden on healthcare systems. This study aimed to explore Diabetes prevalence and Diabetes medication use in diabetics regarding sex, age group, Physical Activity Level (PAL) and Body Mass Index (BMI) by studying possible differences and calculating the risks of developing Diabetes and Diabetes medication use in the population according to their PAL. A cross-sectional study was conducted using data extracted from the Spanish National Health Survey (ENSE2017). The sample was finally composed of 17,710 participants. A descriptive analysis was performed to characterise Diabetes prevalence and Diabetes medication use (Chi-square test and a z-test for independent proportions). Odds Ratios (OR) and 95% Confidence Intervals (CI) were calculated for Diabetes prevalence and Diabetes medication use according to the participants' PAL. Both the Diabetes and Diabetes medication use was higher in men than in women, increasing with age and BMI, and decreasing with increasing PAL (p < 0.001). Higher prevalence levels were observed in the inactive group versus very active or active people (p < 0.001). Inactive people had a higher risk of Diabetes and use of Diabetes medication risk compared to the very active and active groups. Prevalence decreased the higher the PAL both in men and women.

Mapping the Scientific Research on Suicide and Physical Activity: A Bibliometric Analysis.

This research provides an overview of the current state of scientific literature related to suicide and physical activity (PA). A bibliometric analysis of studies published between 1996 and 2022 in The Web of Science (WoS) was carried out, applying the traditional bibliometric laws, using Microsoft Excel and the VOSviewer software for data and metadata processing. A total of 368 documents (349 primary research and 19 reviews) were extracted from 70 WoS categories. The results revealed an exponential increase in scientific production from 2017 to 2022 (R2 = 88%), revealing the United States hegemony being the most productive country, with 156 of the publications (42.4%), the most cited (4181 citations) being the centre of a collaborative network with links to 35 countries and having April Smith, from the Miami University, as the most prolific author (eight publications) and Thomas Joiner, from the Florida State University, as the most cited author (513 citations). The Psychiatry WoS category, with 155 papers, had the highest number of publications, and The Journal of Affective Disorders, from Elsevier, had the highest number of published papers within this category.

Relationships between Physical Activity Level and Pain in the Spanish Population: A Cross-Sectional Study.

Introduction. One third of the world's population suffers from some form of pain. Physical inactivity is one of the causes that reduces physical fitness and may lead to an increase in the prevalence of pain in the population. Aims. To analyse the relationships between the level of physical activity (PAL) and the prevalence and degree of pain, the limitations and impact of pain on daily activities and the use of pain medication in the Spanish population. Hypothesis. PAL is related to pain among Spaniards. Methodology. A cross-sectional study design was used, based on data obtained from the Spanish National Health Survey 2017 with 17,777 participants. A descriptive analysis was performed. Nonparametric statistical tests were used: chi-square statistic to analyse intergroup differences in ordinal variables; Mann−Whitney U test to analyse intergroup differences in continuous variables. A correlation study was also performed between the variables of interest, using Spearman's rho. Results. Relationships were found between PAL and: prevalence of pain, degree of pain, limitations due to pain in usual activities, level of impact in daily activities and use of pain medication in the Spanish population (p < 0.001). Performing moderate and intense PA was related to lower prevalence and degree of pain in the population that performed it, compared to those who only walked or were inactive. Weak correlations were found between the level of PA and the study variables (p < 0.001). Conclusions. High PALs in the population are related to better indicators of pain among Spaniards, appearing to reduce the prevalence and degree of pain, as well as the limitations and impact caused by pain in the daily activities of citizens, and could reduce the use of pain medication in the adult Spanish population.

Associations between Psychological Distress, Perceived Social Support and Physical Activity Level in Spanish Adults with Depression.

Perceived social support (PSS) and physical activity (PA) could help to reduce psychological distress in people with depression. This study aims to analyse the associations between (a) mental health and its dimensions through the Goldberg General Health Questionnaire (GHQ-12), (b) the PA level (PAL), and c) the PSS in the Spanish adult population with psychological distress. This cross-sectional study is based on Spanish National Health Survey 2017 data, including 1670 adults with depression. A descriptive analysis was performed. Differences in medians between sexes were analysed using the Mann-Whitney U test. The Chi-square test was used to assess the independence between sex and PAL. The Kruskal-Wallis' test was performed to analyse possible baseline differences between PAL and continuous variables derived from the GHQ-12. Finally, a correlation study was conducted between the generated variables and the GHQ-12 items, together with the PAL and the Duke-UNC-11, using Spearman's rho correlation coefficients. Weak inverse correlations were found between the GHQ-12 and PAL (rho: -0.214); and PSS (r: -0.286). PAL and PSS showed weak inverse correlations with successful coping (rho: -0.216 and r: -0.265), self-esteem (rho: -0.209 and r: -0.283), and stress (rho: -0.130 and r: -0.232). Thus, higher PAL and SSP is associated with lower psychological distress.

A Cross-Sectional Study on the Associations between Physical Activity Level, Depression, and Anxiety in Smokers and Ex-Smokers.

Introduction: depression and anxiety is one of the most relevant public health problems. The link between smoking and depression has been demonstrated. Regular physical activity (PA) could act as a protector against mental health diseases. Objectives: (1) to explore the prevalence of depression and anxiety in relation to sex and to the condition of smoker and ex-smoker, (2) to study the differences in prevalence proportions according to the frequency and level of PA, and (3) to calculate the probability of presenting depression or anxiety according to the frequency and level of PA. Methods: a cross-sectional study was conducted, based on data extracted from the 2014 and 2020 Spanish European Health Survey and the 2017 Spanish National Health Survey. The sample included 9524, 7813, and 9079 participants, respectively. Descriptive analysis was performed (comparisons using a Chi-square test and z-test for independent proportions). Probability odds ratios of anxiety and depression were calculated according to PA. Results: women had a higher prevalence of depression and anxiety than men (p < 0.001−0.003). Higher levels of prevalence were observed in inactive people versus very active or active people (p < 0.001). Inactive people had a higher risk of depression and anxiety compared to very active people. Conclusion: inactive smokers and ex-smokers had higher levels of prevalence of depression and anxiety than active and very active people. Physical inactivity could increase the risk of suffering these mental disorders in this population. This could affect women more than men.

Associations between Physical Activity Level and Mental Health in the Spanish Population: A Cross-Sectional Study.

Physical inactivity and sedentary lifestyles appear to be critical factors in developing mental health problems, including depression, anxiety, and other diseases in developed societies. This study analysed the associations between physical activity level (PAL) and mental health using the Goldberg General Health Questionnaire (GHQ12) in the Spanish population before the COVID-19 pandemic. A cross-sectional design, based on data from the Spanish National Health Survey (ENSE 2017), the last health survey before the pandemic, was carried out with 17,641 participants. Data did not follow a normal distribution, so non-parametric tests were used to analyse intergroup differences, differences at baseline and post hoc, and correlations between variables. Associations were found between the PAL, mental health and all its dimensions. The groups that performed moderate and intense PAL showed lower values in the GHQ12 questionnaire than those who walked or were inactive. Thus, higher PAL was associated with better mental health indicators, including successful coping, self-esteem and stress. This study provides a framework to compare outcomes between the pre- and post-pandemic periods, as the ENSE is performed every five years.

A Cross-Sectional Study about the Associations between Physical Activity Level, Self-Perceived Health Perception and Mental Health in Informal Caregivers of Elderly or People with Chronic Conditions in Spain.

Providing informal care for older people, or people with chronic conditions, is associated with poorer physical and mental health and reduced quality of life. This task, in many cases, often relies on the women in the immediate family. Physical activity (PA) is a tool to enhance caregivers' physical and mental health and their quality of life. Thus, this study aimed to analyse the associations between the physical activity level (PAL), self-perceived health (SPH) and mental health (SM) and its factors (positive coping, self-esteem, and stress) by conducting a cross-sectional study by using data from in the National Health Survey 2017 (ENSE 2017), the last one before the COVID-19 pandemic. The sample included 2225 caregivers (866 men and 1361 women). Descriptive analysis and non-parametric statistical tests, including chi-square, the Kruskal-Wallis test, the Mann-Whitney U test, and the Spearman's rho correlation coefficient, were used. Dependence relationships were found between PAL and SPH and MH and their factors. The population groups that performed moderate or vigorous PA showed better results in both SPH and MH. Women scored worse than men in all the variables analysed. Hence, intense, or moderate PA practice may improve SPH and MH in Spanish informal caregivers, requiring the implementation of policies and programs considering the differences found between men and women in PAL, SPH, and MH.

Effects of 6-Month Square Stepping Exercise Intervention on Physical and Cognitive Competence, Regucalcin, and Body Composition in Older People: Study Protocol for a Randomised Control Trial.

BACKGROUND: Age-related changes negatively affect physical fitness, body composition, and executive function and produce a decrease in regucalcin level expression in blood. The square-stepping exercise (SSE) is a balance and lower-limb strength training programme used to prevent falls and stimulate cognitive function in older adults. This project aims to analyse the effects of SSE on executive function, regucalcin expression, fall prevention, body composition, and physical fitness in people over 65 years old. METHODS: A randomized controlled trial will be conducted. A total of 90 older people over 65 years old will be recruited and randomly assigned to 2 groups: experimental (n = 45) and control (n = 45). The experimental group will perform an SSE-based intervention for 6 months (2 times per week), while the control group do not follow any treatment. RESULTS: The main outcome will be balance, but other motor (body mass index, upper- and lower-limb strength, flexibility, and speed-agility) and cognitive variables (executive functions and attention) will be assessed. The expression of regucalcin levels will also be evaluated. Therefore, this project aims to analyse the effect of a 6-month SSE intervention on cognitive and motor competence, physical fitness, regucalcin levels, fall risk, and body composition in older people. If the intervention proves to be effective, it could be implemented in centres, entities, and associations specialized in elderly care.

Increased Risks of Mental Disorders: Youth with Inactive Physical Activity.

Before COVID-19, one of the most dangerous pandemics of the 21st century was physical inactivity (PI). Sedentary habits had increased in the last decades, reducing physical condition and increasing non-communicable diseases and mental disorders in the population. This study aimed to analyse the relationships between physical activity level (PAL) and the prevalence of anxiety, depression, and other mental disorders in Spanish young aged 15-35 years and to calculate the odd ratio (OR) of developing from these mental disorders in inactive young people, based on PAL. METHODS: A cross-sectional study based on data from the Spanish National Health Survey 2017 with 4195 participants was conducted. A descriptive analysis was performed. Possible differences between groups were analysed using the non-parametric statistical tests. OR and relative risks for mental disorders in inactive versus others PAL were calculated. RESULTS: Dependence relationships were found between PAL and the prevalence of anxiety, depression, and other mental disorders (p < 0.001). In addition, the risk of developing: anxiety (OR: 6.14. 95% CI: 3.28-11.50), depression (OR: 5.35. 95% CI: 2.40-11.96), and other mental disorders (OR: 8.52. 95% CI: 2.90-25.06) was higher in inactive young people. CONCLUSIONS: PI is associated to high risk of mental disorders in Spanish young people.

Papel de la expresión de regucalcina en el tejido hepático: revisión sistemática / Role of regucalcin expression in liver tissue: systematic review

Objetivo: El propósito de este trabajo fue revisar la literatura científica con relación al papel de la expresión de la regucalcina (SMP30) en el hígado. Método: Se realizó una búsqueda bibliográfica en la base de datos PubMed. Se encontraron 89 artículos. Tras analizar su contenido y aplicar los criterios de inclusión y exclusión, un total de 9 artículos fueron incluidos. Resultados: Se determinó que la expresión de SMP30 es significativamente mayor en el hígado en comparación con otros tejidos como pulmones, bazo, miocardio, próstata y piel (P < 0.05). Se observó, tras obtener muestras de 137 pacientes (30 controles hepáticos normales, 10 con hepatitis B, 49 con cirrosis hepática y 48 con carcinoma hepatocelular (HCC)) que la expresión de SMP30 fue del 100% en todos los tejidos adyacentes al hígado, a excepción del HCC, que solo mostró el 81% de expresión de SMP30 en el hígado. Sobre las concentraciones séricas de SMP30 se observó que 3 grupos distintos mostraron concentraciones diferentes de SMP30: grupo control (1.72 ng/mL), pacientes con hepatitis crónica (3.76 ng/mL) y pacientes con insuficiencia hepática (5.46 ng/mL), teniendo los pacientes con insuficiencia hepática aguda una concentración significativamente mayor de SMP30 que el resto de grupos (P< 0.01), los pacientes con insuficiencia hepática también presentaron una concentración significativamente mayor que el grupo control de pacientes sanos (P< 0.01). Sobre la proliferación de células HepG2 se ha demostrado que la incorporación de manera exógena de SMP30 suprime la elevación del número de células HepG2, revelando así que la proliferación de las células HepG2 fue suprimida con los niveles fisiológicos de SMP30 presente en suero in vitro. Conclusión: La SMP30podría desempeñar un papel fundamental sobre la supervivencia en pacientes con HCC, así como, su posible funcionamiento como proteína protectora de la apoptosis en células HepG2.(AU)

Objective: The purpose of this work has been to review the scientific literature regarding the role of regucalcin expression in the liver. Method: A bibliographic search was carried out on the PubMed database. Eighty-nine articles were found. After analyzing their content and applying inclusion and exclusion criteria, a total of 9 articles were included. Results: It was determined that SMP30 expression is significantly higher in the liver compared to other tissues such as lungs, spleen, myocardium, prostate and skin (P < 0.05). It was observed, after obtaining samples from 137 patients (30 normal liver controls, 10 with hepatitis B, 49 with liver cirrhosis and 48 with hepatocellular carcinoma) that SMP30 expression was 100% in all tissues adjacent to the liver except for hepatocellular carcinoma (HCC), which showed only 81% of protein expression. On serum regucalcin concentrations it was observed, that 3 different groups with different concentrations of SMP30: control group (1.72 ng/ mL), patients with chronic hepatitis (3.76 ng/mL) and patients with liver failure (5.46 ng/ mL) patients with acute liver failure had higher concentrations of SMP30 than patients with hepatitis B (P< 0.01), as well as the serum concentrations of the latter showed to be higher than in healthy patients (P< 0.01). On the proliferation of HepG2 cells it has been shown that the addition of exogenous SMP30 suppresses the elevation of cell numbers, thus revealing that HepG2 cell proliferation was suppressed with the physiological levels of SMP30 present in serum in vitro. Conclusion: Regucalcin could play a key role in survival in patients with hepatocellular carcinoma, as well as its possible role as a protective protein for apoptosis in HepG2 cells.(AU)

Association Between Endocrine Markers, Accumulated Workload, and Fitness Parameters During a Season in Elite Young Soccer Players.

The purpose of this study was to analyze differences between endocrine markers in soccer players, based on playing positions, and correlations between endocrine markers (testosterone, cortisol, growth hormone, and insulin-like growth factor-1), with accumulated workload training and fitness parameters [maximal oxygen uptake (VO2max), countermovement jump (CMJ), and isometric maximal strength (1-RM) of the knee for hamstring (ISH) and quadriceps (ISQ) muscles] during early-, mid-, and end-seasons. Twenty-four elite soccer players under 17 participated in this study. The results showed that there was no difference between levels of the endocrine markers among the different positions of the players. Significant correlations were observed between endocrines parameters and fitness performance (ISQ, ISH, VO2max, and CMJ). Regression analysis showed that 1-RM and VO2max were the best predictors of endocrine markers. These findings demonstrated that the activity profiles of youth soccer players were not influenced by endocrine markers. Also, it may be assumed that endocrines levels can be used to better explain the physical capacities of this population. Finally, endocrines markers may help to predict changes in 1-RM and VO2max.

Influencia de la regucalcina en la pérdida de masa ósea / Influence of regucalcin on bone loss

Objetivo: El propósito de este trabajo ha sido revisar la literatura científica con relación al papel de la regucalcina en la pérdida de masa ósea. Método: Se realizó una búsqueda bibliográfica en la base de datos PubMed. Se encontraron 31 artículos. Tras analizar su contenido y aplicar los criterios de inclusión y exclusión, un total de 13 artículos fueron incluidos. Resultados: La disminución en el contenido de calcio femoral observado en ratones transgénicos con regucalcina se observó con el aumento de la edad, lo que sugiere que la pérdida ósea no se restaura con el modelado óseo. De la misma manera, se encontró que la adición de regucalcina con 1 a 100 nM estimulaba significativamente la actividad basal de NF-kB (P<0.01). Se apreció una disminución significativa en el contenido de ADN en los tejidos metafisarios femorales, con una mayor disminución en hembras que en machos, siendo estos valores: 3.3 mg/g pasaron a ser 2.6 mg/g en las hembras (P<0.01). La reabsorción ósea osteoclástica aumentó en ratones transgénicos con regucalcina machos y hembras con edad creciente. La regucalcina exógena revela efectos supresores sobre la osteoblastogénesis y la mineralización in vitro y que no tuvo efectos sobre la proliferación celular y la apoptosis en las células osteoblásticas en cultivos a corto plazo. Conclusión: La regucalcina desempeña un papel fundamental en el mantenimiento del homeostasis celular y la función de la respuesta celular en relación a la masa ósea.(AU)

Purpose: The aim of this work has been to review the scientific literature regarding the role of regucalcin in bone loss.Method: A bibliographic search was performed in the PubMed database. A total of 31 articles were used. After analyzing its content and applying the inclusion and exclusion criteria, a total of 13 articles were included.Results: The decrease in femoral calcium content observed in regucalcin transgenic mice decreased with increasing age, suggesting that bone loss is not restored with bone modeling. In the same way, it was found that the addition of regucalcin with 1 to 100 nM significantly stimulated the baseline activity of NF-kB (P <0.01). Likewise, there was a significant decrease in the DNA content in femoral metaphyseal tissues, with a greater decrease in females than in males, these values ​​being: 3,3 mg / g became 2,6 mg / g (P <0.01). Osteoclastic bone resorption increased in male and female transgenic regucalcin mice with increasing age. Also, exogenous regucalcin reveals suppressive effects on osteoblastogenesis and mineralization in vitro and that it had no effects on cell proliferation and apoptosis in osteoblast cells in short-term cultures.Conclusion: Regucalcin plays a fundamental role in the maintenance of cell homeostasis and the function of the cellular response in relation to bone mass.(AU)
