The objective of the study was to examine original scientific articles available in data bases for the past twenty-one years (2000-2021) concerning monitoring of anthropometry and physical fitness in young tennis players. A systematic review was carried out in three online data bases (PubMed, LILACS and Web of Science) from January, 2000 to May, 2021. Initially, 73 original articles were identified. After applying criteria of eligibility and exclusion, together with the procedure presented in the PRISMA flowchart, 14 articles were selected and were qualitatively analyzed. The results show the need for further research, mainly in South America and among women. However, it is important to point out that these studies offer anthropometric references very similar to those found in other regions in the world. On the other hand, anthropometry and performance in physical fitness tests show better indicators concerning chronological age, performance in a given modality (national ranking) and specific training. When genders were compared, significant differences were found in terms of anthropometry and physical fitness. Finally, both in women and in men, advanced maturity is associated with better performance in speed tests for movement, strength and muscle power. These data need to be considered in order to improve sports performance, detect talent and prevent injuries in adolescent tennis players. El estudio tuvo como objetivo analizar los artículos científicos originales, disponibles en bases de datos en los últimos veintiún años (2000-2021), acerca del monitoreo de la antropometría y aptitud física en jóvenes tenistas. Se realizó una revisión sistemática en tres bases de datos electrónicas: PubMed, LILACS y Web of Science, entre enero del 2000 a mayo del 2021; se identificaron inicialmente 73 artículos originales que, posterior a la aplicación de los criterios de elegibilidad y exclusión, junto con el procedimiento presentado en el flujograma PRISMA, permitieron obtener 14 artículos, que fueron analizados cualitativamente. Los resultados evidencian que existe la necesidad de mayores indagaciones, especialmente a nivel sudamericano y en las mujeres; no obstante, es importante señalar que estos estudios aportan con referencias antropométricas muy similares a las encontradas en otras regiones del mundo. Por otro lado, la antropometría y el desempeño en pruebas de aptitud física presentan mejores indicadores en relación con la edad cronológica, rendimiento en la modalidad (ranking nacional) y entrenamiento específico. Al comparar por género, existen diferencias significativas en antropometría y pruebas de aptitud física. Finalmente, tanto en mujeres como en hombres, la maduración avanzada se asocia al mejor desempeño en las pruebas de velocidad de desplazamiento, de fuerza y potencia muscular. Es necesario considerar esta información para mejorar el rendimiento deportivo, detección de talento y prevenir lesiones en tenistas adolescentes. O estudo teve como objetivo analisar os artigos científicos originais, disponíveis em bancos de dados nos últimos 21 anos (2000-2021), sobre o monitoramento da antropometria e aptidão física em jovens tenistas.

RESUMEN La obesidad es una enfermedad inflamatoria, crónica, recurrente, progresiva y de etiología multifactorial, que afecta a más 650 millones de personas en el mundo. La carga física, emocional y económica que genera la obesidad no solo guarda relación con sus manifestaciones clínicas, sino también por su impacto a nivel sistémico y a largo plazo. En Chile, el crecimiento económico, la urbanización y la globalización han modificado profundamente el modo de vivir de la población lo que ha favorecido un ambiente obesogénico. Sin embargo, ¿qué factores han repercutido en el desarrollo de obesidad en Chile? ¿cuál ha sido el rol de cada uno de estos factores en el aumento de la prevalencia de esta patología? En la parte 1 de esta revisión discutiremos los principales factores no modificables que han repercutido en su desarrollo, desde la transición epidemiológica que vivió el país en la década de los 70, hasta las patologías endocrinas relacionadas. ABSTRACT Obesity is an inflammatory, chronic, recurrent and progressive disease with a multifactorial aetiology. More than 650 million people live with obesity across the globe, which represents a substantial physical, emotional and economic burden at all levels. Rapid urbanisation, economic growth and globalisation have deeply changed the lifestyles of the Chilean population and have worked in favour of an obesogenic environment. However, what factors have impacted the development of obesity in Chile? What has been the role of each one in the rise of its prevalence? In Chapter one of this literature review, we will discuss the main non- modifiable risk factors that have influenced its development, from the epidemiological transition that the country experienced in the 1970s to the related endocrine pathologies.

RESUMEN Chile tiene una de las tasas de obesidad más altas del mundo. Se estima que para el año 2030 las muertes atribuidas a esta enfermedad alcanzarían a 204 mil personas, incrementándose además los costos económicos asociados a esta patología. Las causas y los factores de riesgo asociados al desarrollo de obesidad son diversos. Sin embargo, existe consenso que una de las maneras más eficaces de prevenir y/o disminuir su prevalencia es abordando los factores de riesgo modificables, a través del fomento de hábitos de vida saludable con un enfoque integral, centrados en la alimentación saludable, práctica de actividad física, prevención del tabaquismo y consumo de alcohol, como también en el cuidado de la salud mental del individuo. No obstante, el desafío es cómo hacer realidad estos buenos propósitos. En este contexto, el objetivo de esta revisión, parte 2, fue investigar los principales factores modificables, con énfasis en los factores individuales, que han repercutido en el desarrollo de obesidad: desde una mirada global hasta el caso particular de Chile. ABSTRACT Chile has one of the highest rates of obesity worldwide. Deaths attributed to obesity are likely to increase to 204,000 by 2030. There will be also a higher economic burden associated with this disease. There are many factors associated with obesity; however, it is known that one of the most effective strategies to decrease its prevalence is reducing modifiable risk factors, such as improving dietary patterns, performing physical activity, avoiding smoking and drinking alcohol as well as improving mental health. Nevertheless, how to make realize these changes is one of the biggest challenges. In this context, the aim of this literature review, chapter 2, was to investigate the main modifiable risk factors, with emphasis on individual factors, associated with the development of obesity in Chile: from a global view to the Chilean context.

Background: It is unknown if nutritional status could influence the accuracy of self-reported physical activity (PA) levels. Aim: To compare PA measured using the international physical activity questionnaire (IPAQ) and by accelerometry (ActiGraph) according to nutritional status in Chilean adults. Material and Methods: This is an observational cross-sectional study that used information from the GENADIO project carried out in Chile between 2009-2011. The sample consisted of 322 people. PA levels and sitting time were determined through the IPAQ self-report questionnaire and ActiGraph accelerometers (GTM1). The nutritional status was determined according to body mass index (BMI). Results: Compared with the measurement made with accelerometry, the IPAQ self-report questionnaire underestimated the levels of light PA, total PA and sedentary time in −171.5, −54.8 and −40.6 min / day, respectively. However, IPAQ overestimated the levels of moderate PA and vigorous PA in 91.0 and 47.3 min/day respectively, compared with accelerometry. Compared with normal weight, obese subjects reported higher levels of moderate PA (105.5 and 48.9 min/day, respectively) and vigorous PA (54.1 and 38.3 min/day respectively). Total PA had a greater delta of underestimation between IPAQ and accelerometer measurements in normal weight than in obese subjects (-122.1 vs −16.5 min/day, respectively). Conclusions: The measurement of PA by means of a self-report questionnaire was discrepant with its objective measurement with an accelerometer. The discrepancy is even higher in obese people.

Background Sleep duration may be a risk factor for cognitive impairment. Aim To investigate the association between sleep duration and cognitive function in Chilean older adults. Material and Methods We analyzed information from 1,384 participants aged > 60 years participating in the National Health Survey 2009-2010 who were assessed with the Mini Mental State Examination (MMSE) and self-reported their average daily sleep hours. Logistic regression analysis was performed to investigate the association between MMSE and sleep duration. Results Compared to those participants who reported sleeping 7 hours per day, those that reported sleeping < 5 hours had a higher odd for cognitive impairment (Odds ratio (OR): 3.66 [95% confidence intervals (CI: 1.69; 7.95], p < 0.01). Similarly, those who reported sleeping > 8 hours per day also showed a higher odd for cognitive impairment (OR: 2.56 [95% CI: 1.32; 4.95], p < 0.01). This association was even stronger for people who reported more than 10 hours of sleep per day (OR: 4.46 [95% CI: 1.32; 4.95], p < 0.01). Conclusions Long and short sleep duration is associated with cognitive impairment in older adults in Chile independent of major confounding factors.

Background: Lifestyle factors could promote healthy ageing. Aim: To investigate the association between physical activity (PA), sedentary behavior and cognitive impairment in Chilean older adults. Material and Methods: We included 1,390 participants from the National Health Survey (2009-2010). The Mini-Mental State Examination was used to diagnose cognitive impairment. Physical activity and sedentary behavior were assessed with the Global Physical Activity Questionnaire (GPAQ). Logistic regression was performed to investigate the associations. Results: Compared with older adults with lower levels of PA (< 48 min/day), those with middle (48-248 min/day) and higher (>248 min/day) levels of PA had lower odds for cognitive impairment (Odds ratio (OR): 0.57 [95% confidence intervals (CI): 0.33; 0.82], p < 0.01 and 0.58 [95% CI: 0.32; 0.83], p < 0.01, respectively). Participants who reported spending more than 8 hours/day sitting had a high odds for cognitive impairment compared to those who spent < 4 hours/day (OR: 3.70 [95% CI: 1.37; 6.03], p = 0.01). Conclusions: Both PA and sedentary behavior were independently associated with cognitive decline independent of major confounding factors in Chilean older adults.

RESUMEN La obesidad es un importante factor de riesgo cardiovascular. No obstante, no todas las personas obesas tienen un perfil metabólico alterado ni todas las personas normo-peso poseen un perfil metabólico normal. Objetivo: determinar la prevalencia de diferentes fenotipos metabólicos asocia-dos al estado nutricional en Chile. Métodos: se incluyeron 1.733 participantes de la Encuesta Nacional de Salud 2009-2010. El estado nutricional (obesidad o normo-peso) fue determinado a través del IMC mientras que la condición metabólica (saludable o no) en base a cuatro parámetros: glicemia, presión arterial, colesterol HDL y triglicéridos. Con estos parámetros de determinaron 4 fenotipos, entre ellos, MUNO: metabólicamente no saludable no obeso y MHO: obeso metabólicamente saludable. Resultados: La prevalencia de MHO fue de 3,3% mientras que un 17,4% presentaba MUNO. Adicionalmente, la prevalencia de MHO disminuyó en la medida que aumentó la edad y la mayor proporción de individuos metabólicamente saludables se encontraba en el grupo de altos ingresos y con un nivel educacional superior (técnico-universitario). Conclusión: Se evidencia una baja prevalencia de MHO, así como también una alta prevalencia de individuos MUNO en la población chilena. Futuras acciones preventivas deberían no sólo considerar el estado nutricional sino también la condición metabólica de la población. ABSTRACT Obesity is an important cardiovascular risk factor. However, not all obese individuals have an unhealthy metabolic pro-file and vice versa. Therefore, the aim of this study was to determine the prevalence of different metabolic phenotypes by nutritional status in Chile. Methods: 1,733 individuals from the National Health Survey 2009-10 were included in this study. Nutritional status (obesity or normal-weight) was determined by BMI whereas metabolic profile was determined through four parameters: Glycaemia, blood pressure, HDL cholesterol and triglycerides. Four metabolic phenotypes were derived, among them: MUNO: metabolically unhealthy and non-obese and MHO: metabolically healthy obesity. Results: The prevalence of MHO in the Chilean population was 3.3% while the prevalence of MUNO was 17.4%. Moreover, the prevalence of MHO decreased as age increased and a greater proportion of metabolically healthy individuals were in the highest gross income group and in the technical-university educational level. Conclusion: This study shows a low prevalence of MHO and a higher prevalence of MUNO in the Chilean population. Future preventive actions should take into account not only the nutritional status, but also the metabolic profile of the population.

RESUMEN A pesar de que la actividad física (AF) es un factor protector contra las enfermedades crónicas no transmisibles, un gran porcentaje de la población no cumple los niveles mínimos recomendados. El objetivo fue investigar como varían los niveles de práctica de AF entre los diferentes grupos etarios en la población chilena. Se incluyeron 5.133 participantes de la Encuesta Nacional de Salud 2009-2010. La AF fue determinada utilizando el cuestionario GPAQ. La inactividad física fue definida como 80 años, respectivamente. Los resultados obtenidos confirman la necesidad de seguir fomentando la práctica regular de AF física a través de todo el ciclo vital, pero en especial sobre los 60 años, ya que este grupo presenta una mayor probabilidad de ser físicamente inactivo. ABSTRACT Although physical activity (PA) is a protective factor against non-communicable diseases, there is an important proportion of the population who do not meet PA guidelines. Our aim was to investigate how adherence to PA guidelines varies across different age groups in the Chilean population. 5,133 participants from the 2009-2010 Chilean Health Survey were included in this study. PA was measured using the Global Physical Activity Questionnaire (GPAQ). Physical inactivity was defined as 60 years the prevalence increased markedly, reaching 63% and 56% for women and men aged >80 years, respectively. These findings confirm the necessity of promoting PA across the lifespan, but more importantly, these results suggest that more promotion and opportunities for engaging in PA should be created especially for older adults, who are more likely to be physically inactive.

The aim of this study was to investigate the association between physical activity (PA), both occupational (OPA) and during leisure time (LTPA), with obesity and cardiovascular risk factors in Chilean adults. 5,157 participants from the Chilean National Health Survey 2009–2010 were included in this study. OPA and LTPA levels were assessed using the Global Physical Activity Questionnaire. The association between both PA with obesity and cardiovascular risk factors was determined using logistic regression. Our findings showed a significant trend between higher LTPA and lower odds for obesity (OR 0.64 [95% CI: 0.53; 0.76], central obesity 0.52 [0.44; 0.61]) and other cardiovascular risk factors including diabetes (OR: 0.72 [0.55; 0.94]), hypertension (OR: 0.59 [0.50; 0.71]) and metabolic syndrome (OR: 0.62 [0.50; 0.78]). In contrast, OPA was only associated with lower odds of diabetes (OR: 0.79 [0.65; 0.98]) and hypertension (0.85 [0.74; 0.98]). In conclusion, LTPA was associated with a lower risk of all major cardiovascular risk factors, whereas OPA was only associated with a lower risk of diabetes and hypertension.

Background: Healthy lifestyles are associated with a better metabolic and cardiovascular health profile. Aim: To investigate the association between a lifestyle score and cardiovascular risk in Chilean adults. Material and Methods: A healthy lifestyle score was derived for 2,774 participants in the Chilean National Health Survey 2009-2010 and based on seven modifiable behaviors (salt intake, fruit and vegetable intake, alcohol consumption, sleep duration, smoking, physical activity and sedentary behaviors). A high score represented a healthier lifestyle whereas a low score represents an unhealthy lifestyle. The association between the lifestyle score and cardiovascular risk factors (obesity, hypertension, diabetes, dyslipidemia and metabolic syndrome), was explored using logistic regression models. Results: One quartile increment in the healthy lifestyle score was associated with a lower risk for obesity (Odds ratio (OR): 0.82 [95% confidence intervals (CI): 0.75 to 0.90], p < 0.01), central obesity (OR: 0.88 [95% CI: 0.81 to 0.96], p < 0.01), diabetes (OR: 0.84 [95% CI: 0.75 to 0.95], p < 0.04) and dyslipidemia (OR: 0.90 [95% CI: 0.83 to 0.98], p = 0.01). These results were independent of major confounding factors. Conclusions: The adherence to a healthy lifestyle is associated with lower cardiovascular risk.

Background: Fat-mass-associated-gene (FTO) is associated with higher energy intake and specific food preferences. Aim: To investigate the association of the FTO genotype with energy intake, macronutrient and alcohol consumption. Material and Methods: Four hundred and nine participants of the GENADIO (Genes, Environment, Diabetes and Obesity) study were included. Energy intake, macronutrient and alcohol consumption were the outcomes of interest. The association of FTO (rs9939609) genotype with these outcomes was investigated using linear regression analyses, adjusting for confounding variables. Results: After adjusting for socio-demographic factors, being a carrier of the risk allele for the FTO gene was associated with a higher energy intake (173 kcal per each extra copy of the risk variant [95% confidence intervals (CI): 45; 301], (P = 0.008). After adjusting for lifestyle factors and body mass index, the association was slightly attenuated but remained significant (144 kcal [95% CI: 14; 274], p = 0.030). Conclusions: The FTO genotype is associated with a higher energy intake.

Background: Although cardiovascular risk factors are associated with an impaired cognitive function, the impact of diabetes on cognitive function in Chilean adults is unknown. Aim: To investigate the association of diabetes or family history of the disease with cognitive impairment in older adults. Materials and Methods: Data from the 2009-2010 Chilean National Health Survey including 1,384 participants aged ≥ 60 years were included in this study. A score below 13 points for the Mini Mental State Examination (MMSE) was considered an indication of cognitive impairment. Logistic regression analyses were performed to assess the association between MMSE, diabetes and family history of the disease. Results: Cognitive impairment increased with age (Odds ratio (OR): 1.83 [95% confidence intervals (CI): 1.53; 2.19], p < 0.01, per 5 years increment in age). This trend was greater in individuals with diabetes (OR: 2.37 [95% CI: 1.68; 3.35], p < 0.01) compared to those without the disease. A similar trend was identified among individuals with a family history of diabetes compared to those without. Conclusions: Older adults with diabetes are more susceptible to develop cognitive impairment.

Conclusions: Not meeting the physical activity recommendations is associated with obesity, diabetes, hypertension and metabolic syndrome, which are important cardiovascular risk factors.

Background: Obesity and sedentary behavior are risk factors acting independently in the development of type 2 diabetes. Aim: To investigate whether the association between diabetes and obesity is modified by the levels of sitting time (ST) in the Chilean population. Material and Methods: We included 4,611 participants from the cross-sectional 2009-2010 Chilean National Health Survey in this study. Diabetes was determined as fasting glucose levels ≥126 mg/dl. Body mass index (BMI) and waist circumference (WC) were measured using standardized protocols. Sitting time was assessed using the Global Physical Activity Questionnaire. The association among diabetes, obesity and ST was determined using logistic regression. Results: The odds for diabetes increased by 3.1-fold in people with high levels of ST and obesity in comparison to those with low levels of ST and normal BMI (Odds ratio (OR): 4.17 [95% confidence intervals (CI): 2.87 to 6.05], P < 0.01). The odds for diabetes increased by 2.7- fold in highly sedentary subjects with central obesity (OR: 3.73 [95% IC: 2.61 to 5.33], P < 0.01) in comparison to those with low levels of ST and normal WC. Conclusions: Elevated levels of sitting time and obesity are associated with a higher odds of developing diabetes.

Resumen Antecedentes: la prevalencia de diabetes mellitus tipo 2 (DMT2) se ha duplicado en los últimos años a nivel mundial, en gran medida como consecuencia de la modificación del estilo de vida de las personas. Existen muchos factores asociados al desarrollo de DMT2; sin embargo, es necesario identificar cuáles de estos factores tienen mayor o menor implicancia en población chilena. En consecuencia, el objetivo de este estudio fue identificar qué factores sociodemográficos, de estilo de vida y salud tienen mayor implicancia con el riesgo de padecer DMT2 en Chile. Metodología: estudio de prevalencia basado en los resultados de la Encuesta Nacional de Salud 2009-2010, a partir de una muestra de 4.700 personas (4.162 normales; 538 diabéticos). Se evaluaron factores sociodemográficos, antropométricos, de estilo de vida, salud y bienestar y variables metabólicas. La asociación entre los factores analizados y DMT2 se determinó mediante regresión logística. Resultados: entre los principales factores de riesgo no modificables asociados a DMT2 se encuentra la edad ≥ 45 años, sexo femenino y antecedentes familiares de DMT2. Los factores de riesgo modificables más significativos fueron: hipertensión arterial, sobrepeso, obesidad, obesidad central, inactividad física y alto nivel de sedentarismo. Conclusión: la identificación y control de los principales factores de riesgo modificables de DMT2, es clave para disminuir la prevalencia de esta patología y mejorar la calidad de vida de la población. Abstract Background: worldwide, prevalence of type 2 diabetes has doubled in the last years, mainly due to unhealthy lifestyle behaviours. They are many risk factors associated with diabetes, however, which factors are associated with diabetes in the Chilean population remains unknown. Therefore, the aim was to determine what risk factors are associated with the development of diabetes in Chile. Methods: four thousand and seven hundred participants from the cross-sectional 2009-2010 National Health Survey were included in this study (4,162 normal; 538 diabetics). Risk factors assessed were socio-demographic, anthropometric, lifestyle, well-being and comorbidities. The association between diabetes and risk factors was examined using logistic regression. Results: the main non-modifiable risk factors associated with diabetes were age ≥ 45 year, female and family history of diabetes; whereas the main modifiable risk factors were hypertension, overweight, obesity, central obesity, physical inactivity and higher levels of sitting time. Conclusion: the identification of modifiable risk factors for DMT2 is key to control and decrease the prevalence of this pathology and to improve the quality of life of the population.
