Niveles de Actividad Física y aspectos saludables en niños de 4 a 6 años de Granada / Physical Activity Levels and health aspects in children from 4 to 6 years old of Granada

El sedentarismo, la inactividad física, así como el sobrepeso y obesidad son los principales problemas de salud física y mental de la población infantil y juvenil, al igual que de adultos. Este tipo de problemática puede deberse principalmente a la alimentación y la cantidad de actividad física realizada desde edades muy tempranas. Hoy en día, los niños y niñas desde muy pequeños se alimentan a diario de comida basura, además de dulces ultra procesados, añadiéndole a esto, la no realización de actividad física y el sedentarismo debido principalmente a las nuevas tecnologías, creando así malos hábitos. El objetivo central de este estudio es relacionar y analizar la Adherencia a la Dieta Mediterránea y el nivel de actividad física de niños de edades comprendidas entre 4 y 6 años, enfocándose para ello en las diferencias existentes entre el género y la edad. Para ello, se ha utilizado un estudio de corte transversal y tipo descriptivo, contando con una muestra de 243 participantes de la provincia de Granada, quienes completaron el test KIDMED. Como resultados se obtuvo que, son los chicos quienes realizan mayor cantidad de actividad física, así como mejor adherencia a la Dieta Mediterránea. Además, cabe destacar que 7 de cada 10 de los participantes necesitan mejorar o poseen una dieta de baja calidad (AU)

A sedentary behaviour, physical inactivity, as well as overweight and obesity are the main physical and mental health problems of children and young people and adults. These problems may be due principally to diet and physical activity from a very early age. Today, children from a very early age are fed daily with junk food, as well as ultra-processed sweets, adding to this, the lack of physical activity and sedentary lifestyles, mainly due to new technologies, thus creating bad habits. The aim of this study is to relate and analyse the adherence to the Mediterranean Diet and the level of physical activity of children aged between 4 and 6 years, focusing on the existing differences between gender and age. A descriptive cross-sectional study was used, with a sample of 243 participants from the city of Granada, completing the KIDMED test. The results showed that boys are the ones who do more physical activity, as well as better adherence to the Mediterranean Diet. In addition, it is worth noting that 7 out of 10 of the participants need to improve or have a poor quality diet (AU)

Stress, Resilience, Burnout and Study Hours in Physical Education Pre-Service Teachers-An Explanatory Model about Gender.

The process of becoming a public teacher in Spain requires a long period of preparation. This long period of preparation has an impact on the psychosocial environment of the candidates. Differences have been observed in the psychosocial area according to gender in pre-service teachers. This research aims to study the relationship between the study hours per day, stress, burnout syndrome and resilience according to gender and to study the differences in the effects according to gender using multigroup equation modeling. A multigroup structural equation analysis has been proposed according to the gender of the participants. Parametric tests were used for the descriptive analysis of the results. The sample consists of 4117 participants, 1363 males and 2754 females. The instruments used to collect the data were a self-made questionnaire, Perceived Stress Questionnaire, Connor-Davidson Resilience Scale and Maslach Burnout Inventory. All the instruments have been validated and adapted to the sample. The data reveal that there are variations in the effects of the variables according to the gender of the participants. In conclusion, it is affirmed that gender is a very important factor in coping with the competitive examination process for state-public-teaching institutions, as well as in avoiding the appearance of disruptive states generated by this preparation process.

Are there differences between Mediterranean diet and the consumption of harmful substances on quality of life?-an explanatory model in secondary education regarding gender.

Background: Adolescence is a key life stage in human development. It is during this stage of development that healthy and physical behaviors are acquired that will last into adulthood. Gender differences in the acquisition of these behaviors have been observed. This research aims to (a) study the levels of Mediterranean diet adherence, quality of life and alcohol and tobacco consumption as regarding the gender of the participants and (b) study the effects of the variable adherence to the Mediterranean diet, alcohol consumption and tobacco consumption on quality of life as a function of the gender of the participants. Methods: A non-experimental, cross-sectional, exploratory study was carried out in a sample of 1,057 Spanish adolescents (Average Age = 14.19; Standard Deviation = 2.87). Results: The comparative analysis shows that the male teenagers shows a higher Mediterranean diet adherence compared to the male adolescents (p ≤ 0.05) and a higher consumption of alcoholic beverages (p ≤ 0.05). On the contrary, adolescent girls show a higher consumption of alcoholic beverages than male participants (p ≤ 0.05). The exploratory analysis indicates that for boys, alcohol consumption has a beneficial effect on the quality of life of adolescents (ß = 0.904; p ≤ 0.001). Conclusion: In this case, participants show differences in the levels of Mediterranean diet adherence, consumption of harmful substances and quality of life according to gender. Likewise, there are different effects between the variables according to gender. Therefore, gender is a key factor to consider during adolescence.

Relationship between Physical Activity, Mediterranean Diet and Emotional Intelligence in Spanish Primary Education Students.

There is an international social concern about the low levels of physical activity among young people. It is essential to know what factors influence the practice of physical activity in order to design effective proposals for health promotion. The study aims to: (1) classify primary school students according to their levels of out-of-school physical activity, Mediterranean diet, emotional attention, emotional clarity and emotional repair; (2) analyse descriptively and correlationally the adolescents' profiles of out-of-school physical activity, Mediterranean diet and emotional attention, clarity and repair. The study design was cross-sectional and descriptive-correlational. The sample consisted of 293 children aged 10-12 years in Granada (Spain). An ad hoc socio-academic questionnaire, the KIDMED test and the Trait Meta-Mood Scale (TMMS-24) were used for data collection. Four clusters were identified by the Ward's method and participants were classified using the K-means method. Subsequently, cluster classification was validated through the MANOVA test (F (861) = 106.12; p ≤ 0.001; f = 1.95). The strongest correlation was obtained in cluster 1 between emotional clarity and emotional repair (r = 0.56; p ≤ 0.01). In conclusion, the mean values of time spent in out-of-school physical activity, Mediterranean diet, emotional attention, emotional clarity and emotional repair of students are adequate and vary according to sex. There are significant differences among the physical activity levels of all clusters, as well as among the emotional variables of attention, clarity and repair. In addition, the correlations between the variables studied vary in each cluster.

Associations of Mediterranean Diet, Psychological Wellbeing and Media Pressure on Physical Complexion and Effect of Weekly Physical Activity Engagement in Higher Education.

Nowadays, the media has the power to encourage active and healthy lifestyles; however, it can have a negative impact on body image and psychological wellbeing.

Mediterranean diet adherence on self-concept and anxiety as a function of weekly physical activity: an explanatory model in higher education.

Introduction: Scientific literature has now demonstrated the benefits of an active lifestyle for people's psychological health. Based on the above statement, the aim was to (a) evaluate and adjust a structural equation model containing the variables anxiety, self-concept, and Mediterranean diet adherence and (b) contrast the proposed theoretical model by studying the differences between the variables according to the level of weekly physical activity in a sample of 558 university students. Methods: A non-experimental, exploratory, cross-sectional investigation has been proposed. Instruments such as the PREDIMED Questionnaire, the Beck Anxiety Inventory, the International Physical Activity Questionnaire, and the Form 5 Self-Concept Questionnaire were used to collect data. Results and discussion: The results illustrate that students showing low adherence to the Mediterranean diet had higher levels of anxiety (M = 0.95) than those showing a high degree of adherence (M = 0.75). It is also observed that young people with a high degree of adherence to the Mediterranean diet report higher scores in the different dimensions of self-concept compared to young people with a low degree of adherence. In conclusion, it is affirmed that young people who show a high degree of adherence to this dietary pattern show lower levels of anxiety and greater recognition of the different areas of their self-concept.

Effectiveness of a Judo Intervention Programme on the Psychosocial Area in Secondary School Education Students.

Currently, many combat sports are pedagogically conceived as uneducational and unreliable for the development of young people. The present research aims to investigate the influence of a Judo intervention programme on the motivational climate towards sport, aggressive behaviour, emotional intelligence, and self-concept in secondary school students and to establish the relationships between them. This objective was broken down into (a) developing an explanatory model of the variables mentioned above and (b) testing the model equations through a multi-group analysis in terms of pre-test and post-test. The present study conducted a pre-post-test quasi-experimental design with a single experimental group. The sample consisted of a total of 139 adolescents (12.67 ± 1.066), 50.4% of whom were male (n = 70) and 49.6% female (n = 69). The results show that the intervention decreased all types of aggression and increased levels of emotional intelligence. An increase in social, physical and academic self-concept and decreases in the family and emotional areas were also observed. Finally, for the motivational climate, a tendency towards the ego climate to the detriment of the task climate was observed. It is concluded that the Judo intervention programme is effective in decreasing aggressive behaviour and effective in increasing levels of emotional intelligence and self-concept.

Study of the Effects of Physical-Activity Practice and Adherence to the Mediterranean Diet on Emotional Intelligence in Elementary School Education Students.

Research shows that regular physical exercise and a healthy lifestyle have a beneficial effect on the health of adolescents. Other studies have also shown that gender is also a determining factor when it comes to leading an active and healthy lifestyle. The aims of this study are (a) to develop a structural-equation model formed by the variables of emotional intelligence, physical-activity practice, and adherence to the Mediterranean diet and (b) to consider that model through a multigroup analysis. A descriptive, comparative, and cross-sectional study was carried out. The sample consisted of 567 primary school students. The KIDMED, PAQ-C, and TMMS-24 questionnaires were used for data collection. We found that there are differences in the effects of the practice of physical activity and adherence to the Mediterranean diet on the emotional domain. We also concluded that, during adolescence, gender is a key element in acquiring a healthy and active lifestyle.

The interplay between academic performance, emotional intelligence, and self-concept as predictors of violent behavior in higher education: a multi-group structural equation modeling.

Higher education is a focus of increasing violent behavior. The evidence suggests an obsession to achieve the best academic performance in order to access working life. This research aims to develop an explanatory model of violent behavior and its relationship with self-concept and emotional intelligence according to in relation to their academic performance. A sample of 932 Spanish undergraduate students participated in the multi-group structural equation modeling. Findings revealed that students who have a higher academic performance have problems to control and regulate their emotions, showing signs of direct and indirect violence. Moreover, it was found that that emotional intelligence and self-concept have a direct influence on episodes of violent behavior, with academic performance being a key component affecting each variable. The present study provides some implications and suggests some avenues for future research.

An Explanatory Model of Violent Behavior, Self-Concept, and Alcohol, Tobacco, and Cannabis Consumption in Secondary Education Students.

Background: Current scientific evidence establishes that regular physical activity engagement provides numerous physical and mental benefits. Thus, the present research aims at examining the relationships between violent behavior, self-concept, and consumption of alcohol, tobacco, and cannabis. Specifically, two objectives were defined: (a) analyze and establish the relationships between violent behaviors, the different dimensions of self-concept, and the consumption of alcohol, tobacco, and cannabis as a function of physical activity engagement, (b) define and examine a proposed explanatory model, and (c) analyze the effect of self-concept on alcohol and tobacco consumption and physical activity engagement based on the explanatory model developed. Methods: For this purpose, a nonexperimental (ex post facto), descriptive, and cross-sectional study was conducted. For data collection, a sociodemographic questionnaire was administered alongside the Self-Concept Form 5 and the School Victimization Scale. Results: It was shown that individuals engaging in more than three hours of physical exercise per week scored more highly on the social, family, physical, and emotional aspects of self-concept, whilst those who do not meet this criterion scored more highly on the academic aspect and on physical and verbal victimization. Conclusions: The present research concludes that engagement in more than 3 hours of physical activity per week led to benefits in a number of domains of self-concept whilst, at the same time, increasing levels of violence.

Levels of Physical Activity, Family Functioning and Self-Concept in Elementary and High School Education Students: A Structural Equation Model.

In the adolescent population there is great concern about low levels of physical activity and low levels of family awareness of the benefits of physical exercise on physical and mental health. This study aims to determine the influence of physical activity levels, family functioning and self-concept in primary and secondary school students, as well as to develop a structural equation model as a function of weekly physical activity time. A descriptive, cross-sectional, comparative study was conducted on whether students engage in more than three hours of physical activity per week. To collect the data, instruments validated by the scientific community were used, such as the Adaptability, Partnership, Growth, Affection, and Resolve family questionnaire (APGAR) and the self-concept questionnaire form 5. The results show that those students who engage in more than 3 h of physical activity per week have higher levels of family functioning than those who do not meet this sport criterion. In addition, physically active students show higher scores on all dimensions of self-concept than those who practice less than 3 h of physical activity per week. Finally, as a conclusion, it can be affirmed that the amount of physical activity practice brings benefits to student's mental health.

Mass media pressure on physical build, psychological well-being and physical-healthy profile. An explanatory model in adulthood.

Background: The pressure exerted by the media on mental image, psychological well-being and the physical-dietary sphere is of vital interest in understanding human behavioral patterns at different stages of development. The present research reflects the objectives of developing an explanatory model of the associations between media pressure and physical build on psychological well-being, physical activity and the Mediterranean diet and testing the structural model using a multi-group model according to participants' stage of adulthood development. Methods: A descriptive, non-experimental, cross-sectional study was carried out on a sample of 634 participants aged between 18 and 65 years (35.18 ± 9.68). An ad hoc socio-demographic questionnaire, Sociocultural Attitudes Towards Appearance Questtionnaire-4, Psychological Well-Being Scale, Predimed questtionnaire and International Physical Activity Questionnaire-Short Form were used for data collection. Results: Participants in early adulthood show higher scores for media pressure and for pressure on physical build. It is also observed that participants in middle adulthood show higher scores for psychological well-being and physical activity levels. Conclusions: In conclusion, it can be seen that there are a large number of physical, physical-health and psychological differences in each of the phases of adulthood.

Practice of physical activity its association with violence, emotional intelligence, and self-concept development in undergraduates / Práctica de actividad física y su asociación con la violencia, la inteligencia emocional y el desarrollo del autoconcepto en estudiantes universitarios / Prática da actividade física a sua associação com a violência, inteligência emocional, e desenvolvimento do auto-conceito em estudantes universitários

Hoy en día se sabe que la actividad física influye positivamente en la salud tanto física como mental. Por ello, este estudio pretende arrojar luz sobre hasta qué punto la inteligencia emocional y el autoconcepto pueden ser útiles para reducir las conductas violentas en los deportistas españoles. Se realizó un estudio transversal sobre una muestra formada por 457 estudiantes universitarios (23,86 ± 12,24), que cursaban diferentes titulaciones en la Universidad de Granada. Los instrumentos utilizados fueron un cuestionario demográfico, la versión española de la Forma 5 de Autoconcepto, la versión española de la Escala de Violencia Escolar y la versión española del Inventario de Autoinforme de Schutte (ISIS). Los resultados revelan que casi la totalidad de la muestra practicaba actividad física con regularidad; además, las dimensiones mejor valoradas fueron la gestión de la autoestima en cuanto a la inteligencia emocional, la agresión relacional pura en cuanto al tipo de violencia, y la académica en cuanto al autoconcepto. Por último, se observó una correlación negativa entre la inteligencia emocional general y todos los tipos de violencia, así como entre todos los tipos de violencia y el autoconcepto académico. (AU)

Nowadays, physical activity is known to have a positive influence on both physical and mental health. Therefore, this study aims at shedding light on the extent to which emotional intelligence and self-concept may be useful to reduce violent behaviours in Spanish sportspeople. A cross-sectional study was conducted on a sample consisted of 457 undergraduates (23.86 ± 12.24), who were studying different degrees in University of Granada. Instruments used were a demographic questionnaire, the Spanish version of the Self-Concept Form 5, the Spanish version of the School Violence Scale, and the Spanish version of the Schutte Self-Report Inventory (SSRI). Results reveal that nearly all of the sample regularly practised physical activity; moreover, the highest-rated dimension were Self-Emotional management as regards emotional intelligence, Pure Relational Aggression as for the type of violence, and academic with regards to self-concept. Lastly, there was a negative correlation between general emotional intelligence and all types of violence, as well as between all the types of violence and academic self-concept. (AU)

Hoje em dia, sabe-se que a actividade física tem uma influência positiva tanto na saúde física como mental. Por conseguinte, este estudo visa lançar luz sobre até que ponto a inteligência emocional e o auto-conceito podem ser úteis para reduzir comportamentos violentos nos desportistas espanhóis. Foi realizado um estudo transversal sobre uma amostra constituída por 457 estudantes universitários (23,86 ± 12,24), que estavam a estudar diferentes graus na Universidade de Granada. Os instrumentos utilizados foram um questionário demográfico, a versão espanhola do Formulário de Auto-Conceito 5, a versão espanhola da Escala de Violência Escolar, e a versão espanhola do Inventário de Auto-Relatórios Schutte (SSRI). Os resultados revelam que quase toda a amostra praticava regularmente actividade física; além disso, a dimensão mais elevada foi a gestão auto-mocional no que diz respeito à inteligência emocional, Pura Agressão Relacional no que diz respeito ao tipo de violência, e académica no que diz respeito ao auto-conceito. Finalmente, houve uma correlação negativa entre a inteligência emocional geral e todos os tipos de violência, bem como entre todos os tipos de violência e o auto-conceito académico. (AU)

Physical Activity Time, Alcohol Consumption, Mediterranean Diet, and Anxiety in Education Science Students.

Student lifestyles change during university. This research aimed to classify university students according to their levels of physical activity, alcohol consumption, adherence to the Mediterranean diet, and anxiety and studied the relationships between the variables using a multigroup equation model according to gender. The sample was composed of 549 participants (M = 23.06; S.D. = 6.22), of whom 409 were women and 140 were men. Validated and adapted instruments such as the Beck Anxiety Inventory, the PREDIMED Questionnaire, and the Alcohol Use Disorder Identification Test were used. The data revealed four clusters through Ward's method and the k-means method. Regarding the exploratory model, differences were found in the effects of the variables according to sex. In conclusion, alcohol consumption was positively associated with the Mediterranean diet, and physical activity was negatively associated with the Mediterranean diet and anxiety.

Relationship between Learning and Psychomotor Skills in Early Childhood Education.

Psychomotor skills are, among others, an aspect particularly valuable for structuring the teaching-learning process of infant schoolchildren. For this reason, a study was carried out with the aim of describing and comparing the socio-demographic, psychomotor, and learning levels of schoolchildren in the second stage of infant education. Ninety-five pupils from the second cycle of infant education in the capital of Granada took part in this study. A sociodemographic questionnaire, the movement assessment battery for children-2 (MABC-2), and the preschool learning behaviour scale (PLBS) were used to collect data. The main results show that manual dexterity appears as the main motor factor and similar figures in the three dimensions of learning behaviours. On the other hand, balance and learning behaviours were higher in 6-year-old schoolchildren. In terms of gender, girls obtained higher values for the level of the learning behaviour variables. A positive correlation was found between the dimensions of learning and motor activity.

Emotional Intelligence, Physical Activity Practice and Mediterranean Diet Adherence-An Explanatory Model in Elementary Education School Students.

Currently, there is a global concern with regard to the lifestyles of young people. This study aims to study the association between Mediterranean diet adherence, emotional intelligence and physical activity practice in teenagers in the last cycle of elementary education. In turn, this objective is divided into (a) developing an explanatory model of the practice of physical activity, Mediterranean diet adherence and emotional intelligence; and (b) developing a multi-group model according to the gender of the participants. A descriptive, cross-sectional, comparative study was conducted in a sample of 293 elementary school students (M = 11.45; S.D = 0.31). The instruments used were an ad hoc socio-demographic questionnaire, the Trait Meta Mood Scale-24, the KIDMED questionnaire and the Physical Activity Questionnaire for Older Children. The results show that males show a positive relationship between adherence to the Mediterranean diet and emotional intelligence and between emotional intelligence and physical activity. In contrast, in the case of females, a negative relationship was observed between emotional intelligence and physical activity. In conclusion, it can be seen that gender plays a fundamental role in adolescence, being a key factor influencing an active and healthy lifestyle.

The Relationships between Physical Activity, Screen Time and Sleep Time According to the Adolescents' Sex and the Day of the Week.

This study had two aims: (1) to identify the levels of physical activity, screen time and sleep time of adolescents according to the sex of the participant and the day of the week; (2) to find out the relationships between physical activity, screen time and sleep time according to the sex of the participant and the day of the week. The study design was non-experimental, descriptive-correlational and cross-sectional. The sample consisted of 694 adolescents in Compulsory Secondary Education from Soria (Spain). Four by One-Day Physical Activity Questionnaires were used to measure levels of physical activity, screen time and sleep time. Levene's test and Student's t-test were used to calculate the difference between the means of the variables. Pearson's test was used to calculate bivariate correlations between variables. Results showed higher levels of screen time in males (136.93 min/day ± 81.548). Screen time, sleep time and moderate−vigorous physical activity are higher during the weekend. Positive relationships were found between screen time and light physical activity (rmales = 0.274; p ≤ 0.01; rfemales = 0.065; p > 0.05). The correlations between moderate−vigorous physical activity and screen time were negative (rmales = −0.282; p ≤ 0.01; rfemales = −0.187; p ≤ 0.05). The relationship between screen time and sleep time was negative in males (r = −0.135; p ≤ 0.05). In conclusion, the levels of physical activity, screen time and sleep time vary according to the sex of the participants and the day of the week.
