Aging well is directly associated to a healthy lifestyle. The focus of this paper is to relate individual wellness with medical image features. Non-linear trimodal regression analysis (NTRA) is a novel method that models the radiodensitometric distributions of x-ray computed tomography (CT) cross-sections. It generates 11 patient-specific parameters that describe the quality and quantity of muscle, fat, and connective tissues. In this research, the relationship of these 11 NTRA parameters with age, physical activity, and lifestyle is investigated in the 3,157 elderly volunteers AGES-I dataset. First, univariate statistical analyses were performed, and subjects were grouped by age and self-reported past (youth–midlife) and present (within 12 months of the survey) physical activity to ascertain which parameters were the most influential. Then, machine learning (ML) analyses were conducted to classify patients using NTRA parameters as input features for three ML algorithms. ML is also used to classify a Lifestyle index using the age groups. This classification analysis yielded robust results with the lifestyle index underlying the relevant differences of the soft tissues between age groups, especially in fat and connective tissue. Univariate statistical models suggested that NTRA parameters may be susceptible to age and differences between past and present physical activity levels. Moreover, for both age and physical activity, lean muscle parameters expressed more significant variation than fat and connective tissues.

BACKGROUND: The health-related quality of life construct (QoL) implies a relationship with eating habits (EA) and physical activity (PA). Sociodemographic and anthropometric variables (gender, age and Body Mass Index - BMI) are highlighted in the definition of healthy lifestyle habits promotion strategies. OBJECTIVE: We aim to characterize and relate PA, EA and QoL in children/youth and explore gender, age and BMI influences. METHODS: It is a non-experimental study, with 337 children/youth, ages between 8 and 17 years (12.61±2.96), mostly from the rural inland of Portugal. In data collection we used a sociodemographic and anthropometric questionnaire, a weekly register table of EA and Kid-Kindl (QoL). Statistical analysis (p <  0.05) were performed in SPSS-IBM 25. RESULTS: Lower BMI was associated with better EA (p <  0.001), PA (p <  0.05) and self-esteem (p <  0.01) and worse scores on family subscale of QoL. Female showed higher fruit intake (p <  0.05). The older has shown better results. PA is positively correlated with QoL (p <  0.01) and EA (p <  0.05). CONCLUSIONS: It is important to explore other relevant social and family dimensions, to promote intervention programs with parents, school and community, as well as healthy practices policies. The intervention in these age groups is critical for a longer-term impact in improving healthy life habits.

Aims: The objective was to investigate moderate-to-vigorous physical activity levels (MVPA) of primary school children at baseline of the Health Oriented Pedagogical Project (HOPP), Norway. Methods: Data on 2123 children aged 6–12 years were included for analysis (75% participation rate). Average minutes per day in MVPA was objectively measured using accelerometry based on seven-day averages. The sample was analysed for age-, sex-, socioeconomic-, and season-related patterns. A linear regression investigated the moderating effect of these factors as well as body mass index and waist circumference. Results: Some 86.5% of the sample had at least 60 min/day MVPA, averaging 90.7 min/day. The main differences in daily averages were between age groups 6½–9 and 10–12 ( p < .05). Boys (95.8 min/day, 95% CI: 94.1–97.5) were more active than girls (85.6 min/day, 95% CI: 83.9–87.2) in all age groups ( p < .0001). MVPA was lower by 3.5 min ( p < .0001) per additional year of age in the linear regression (R2 = 0.176) and was reduced by 20 min less per day in MVPA in the winter months compared with the summer months ( p < .0001). Conclusions: Physical activity levels are already in decline from 6–7 years old and are likely to continue to decline into adolescence. Interventions must therefore focus on primary school children.

En los últimos años se está creando un importante problema de sedentarismo en la infancia. A la hora de diseñar programas de intervención para fomentar la práctica de actividad física es necesario obtener información precisa sobre los niveles de práctica de la población infantil así como de los posibles determinantes de la práctica. Para ello se ha diseñado un estudio donde se evalúan los niveles de práctica de niños y niñas de 6 a 12 años de actividad física. Las conclusiones que se desprenden del estudio realizado son: un alto porcentaje de sujetos no realizan ejercicio físico (34,4%), observándose diferencias entre niños y niñas; se puede afirmar que las niñas practican menos que los niños (35,4% versus 24,9%). Por otro lado, el porcentaje de sujetos físicamente activos es de un 31,2% cuando se considera la recomendación más extendida, de tres o más horas a la semana. Los resultados obtenidos confirman la necesidad de incentivar programas de intervención en niños y jóvenes, aconsejando la práctica de actividad física, prestando especial interés a las chicas.Palabras clave: Salud. Actividad física. Deportes. Niños y adolescentes.Abstract: In recent years, is creating a major problem of physical inactivity in childhood. To design intervention programs that promote physical activity is necessary to obtain accurate information about levels of practice of the child population as well as the possible determinants of the practice. This was carried out a cross-sectional and descriptive. The sample is representative of students attending school in the city of Torrevieja and was selected by a pro rata basis. Participants in the study were 1248 students from thirteen primary schools offering primary education in the city of Torrevieja. The study evaluated physical activity levels of children aged 6 to 12 years. The instrument used in this study is a questionnaire (Latorre, 2006). The version used shows adequate factorial structure (Latorre, 2006). It is an instrument designed to assess the variables of healthy lifestyle among young people and teenagers. The results confirm the need to provide adequate education about healthy lifestyles and enhance the development of intervention programs for children and youth, counseling on diet and physical activity with particular interest in the girls, who are less physically active group and increased risk of disorders.Keywords: Health. Physical activity. Sports. Children and adolescents.

BACKGROUND Physical activity is an important health behavior, due to its association with many physical and mental health conditions. During distressing events, such as the COVID-19 pandemic, there is a concern that physical activity levels may be negatively impacted. However, recent studies have shown inconsistent results. Additionally, there is a lack of studies in Australia on this topic. OBJECTIVE The aim of this study is to investigate changes in physical activity reported through the 10,000 Steps program and changes in engagement with the program during the COVID-19 pandemic. METHODS Data between January 1, 2018, and June 30, 2020, from registered members of the 10,000 Steps program, which included 3,548,825 days with step data, were used. The number of daily steps were logged manually by the members or synced automatically from their activity trackers connected to the program. Measures on program usage were the number of new registered members per day, the number of newly registered organizations per day, the number of steps logged per day, and the number of step entries per day. Key dates used for comparison were as follows: the first case with symptoms in Wuhan, China; the first case reported in Australia; the implementation of a 14-day ban for noncitizens arriving in Australia from China; the start of the lockdown in Australia; and the relaxing of restrictions by the Australian Government. Wilcoxon signed-rank tests were used to test for significant differences in number of steps between subgroups, between engagement measures in 2019 versus 2020, and before and after an event. RESULTS A decrease in steps was observed after the first case in Australia was reported (1.5%; <i>P</i>=.02) and after the start of the lockdown (3.4%; <i>P</i>&lt;.001). At the time that the relaxing of restrictions started, the steps had already recovered from the lockdown. Additionally, the trends were consistent across genders and age groups. New South Wales, Australian Capital Territory, and Victoria had the greatest step reductions, with decreases of 7.0% (<i>P</i>&lt;.001), 6.2% (<i>P</i>=.02), and 4.7% (<i>P</i>&lt;.001), respectively. During the lockdown, the use of the program increased steeply. On the peak day, there were more than 9000 step entries per day, with nearly 100 million steps logged per day; in addition, more than 450 new users and more than 15 new organizations registered per day, although the numbers decreased quickly when restrictions were relaxed. On average per day, there were about 55 new registered users (<i>P</i>&lt;.001), 2 new organizations (<i>P</i>&lt;.001), 25.6 million steps (<i>P</i>&lt;.001), and 2672 log entries (<i>P</i>&lt;.001) more in 2020 compared to the same period in 2019. CONCLUSIONS The pandemic has had negative effects on steps among Australians across age groups and genders. However, the effect was relatively small, with steps recovering quickly after the lockdown. There was a large increase in program usage during the pandemic, which might help minimize the health impact of the lockdown and confirms the important role of physical activity programs during times of distress and lockdowns.

Millennials are currently the most prominent age demographic in Indonesia, a generation that has the highest number of people compared to other age groups that wholly consist of peope in productive age. As the prominent demographic group, their behaviour and lifestyle is an important trend that needs to be observed. Their 2 most dominant lifestlye are: 1. Food, a big part of their lifestyle, Millennials spend most of their money on food, especially on dining out, and; 2. Sedentary Lifestyle, 84% of Jakarta citizen’s profession can be categorized as a job with passive physical activity, furthermore the advancement of digital technology has made daily activity less active. These things needs to be paid attention to, as both of them are the main cause of obesity, which itself is a major cause of 4 of 5 illness that caused death in Indonesia, and can be observed in 37.1% of adults in Jakarta. To mitigate this, a program is designed to solve this issue preventively, by instilling a healthy bevahiour in their daily life. The chosen design method is typology. Function-wise it is based on wellness center, which promotes health not only by medicine but also through building a healthy lifestyle. Shape-wise, is to design a building which passively promotes healthy lifestyle by its shape. Based on these, the proposed program is Integrated Health Facility, which is an integrative medicine based  facility. The main focus of this program is diet nutrition and physical activiy, with the main program categorized as food, pyhsical activity, clinic, and health community. Stair is the main concept, used as the main circulation and split level design, to passively encourage physical activity. Abstrak Generasi Millennial adalah sebuah generasi yang sedang mendominasi di Indonesia, sebagai generasi yang keseluruhannya merupakan usia produktif dengan persentase terbesar dibandingkan dengan generasi usia lainnya. Sebagai generasi yang dominan, gaya hidup dan perilaku mereka layak menjadi perhatian. Dua hal yang dominan adalah: 1. Makanan, sebuah bagian besar dari gaya hidup mereka, terlihat dari pengeluaran Generasi Millennial untuk makanan, khususnya untuk makan di luar, merupakan pengeluaran terbesar mereka, dan; 2. Sedentary Lifestyle, 84% profesi penduduk Jakarta merupakan profesi yang tidak aktif, selain itu dengan kemajuan teknologi digital membuat aktivitas sehari-hari semakin menjadi kurang aktif. Kedua gaya hidup ini perlu menjadi perhatian, karena keduanya merupakan penyebab utama dari Obesitas, yaitu penyebab 4 dari 5 penyakit penyebab kematian tertinggi di Indonesia, serta diderita oleh 37.1% penduduk dewasa Jakarta. Sebagai upaya penyelesaian dari masalah ini, sebuah program dan fasilitas dirancang untuk menyelesaikan masalah ini secara preventif, yaitu melalui menumbuhkan kebiasaan gaya hidup sehat. Metode perancangan yang digunakan adalah tipologi. Secara fungi mengikuti trend wellness center, yaitu kesehatan tidak hanya melalui pengobatan, tetapi juga melalui gaya hidup sehat. Selain itu secara bentuk, yaitu menghasilkan bangunan yang melalui bentuknya mendorong gaya hidup sehat. Berdasarkan ini, bangunan yang dihasilkan adalah Integrated Health Facility, yaitu sebuah fasilitas kesehatan yang secara menyeluruh. Fokus utama dari fasilitas ini merupakan nutrisi (makanan) dan aktivitas fisik, dengan program utama yang ditawarkan dapat dikategorikan menjadi makanan, aktivitas fisik, klinik serta komunitas kesehatan. Tangga menjadi konsep utama dari bangunan, yaitu sebagai sirkulasi dan permainan split level, untuk mendorong aktivitas fisik secara pasif.

Describes a complex of methods for the implementation of scientific research, the information of those who were researched is represented, methodology and methods of the research are described.Covers a wide range of problems, in particular a comprehensive study of motivation for both physical activity (needs, interests, self-conception, performance, leisure and factors of a healthy lifestyle), and for learning and succeeding.Objective: to study gender peculiarities and differences in self-description of physical development of schoolchildren. Material: The study involved schoolchildren of 5-11 grades (n = 638), among them: young men - 282, girls - 386. Correlation analysis of self-description of subjective indexes of physical development of schoolchildren has been conducted. Results: Using the results of the testing “Self-description of physical development”. It was found out that the correlational connection of indicators of self-description of the physical development of respondents of all ages have certain gender differences. We found that general self-esteem of boys of primary school age is affected by more indicators than of the girls. Young men associate with their own self-esteem and physical qualities: coordination and flexibility. Girls associate their health with physical activity and their own physical abilities. Conclusions: The obtained results of the scientific experiment give us the right to assert the existence of age and gender differences between the indicators of self-description of boys and girls who are engaged in and not engaged in sports. The study of self-assessment of physical boys and girls of different ages helped to draw conclusions about common and different priorities of the motivational sphere of physical culture and sports in gender and age.

Abstract Presumably, individuals are taught skills throughout their primary education that are required to live a healthy lifestyle throughout the lifespan. The primary purpose of this study was to assess adult psychological need satisfaction in relation to high school participation. Participation included university employees and students of two mid-sized universities and members of a state health organization. Participants (n = 512) completed the Psychological Need Satisfaction in Exercise (PNSE) and the International Physical Activity Questionnaire (IPAQ). The current study found modest associations between measured motivation constructs on physical activity levels. Standardized coefficients report competence and autonomy had a significant effect on physical activity in predicting adult physical activity levels. Results of this study provide insight into the determinants underlying the development of physical activity tendencies in adults and suggest high school physical education and sport participation have an equal influence on adult physical activity levels.
