          Abstract

          Resumen La obesidad se ha convertido en uno de los problemas de salud más graves de la sociedad y se relaciona con multitud de afecciones y complicaciones en la pubertad. Mediante este estudio descriptivo, transversal y poblacional se pretende, en primer lugar, conocer las diferencias entre las variables del estilo de vida y la condición física de cada género y, en segundo lugar, conocer los determinantes relacionados con el estilo de vida y la condición física en una población española de 10 a 12 años de edad con nivel socioeconómico medio. Las variables analizadas fueron el IMC, las variables de condición física (agilidad, flexibilidad y capacidad cardiorrespiratoria) y las variables de los hábitos de salud (calidad y frecuencia alimentaria, práctica de actividad física, sedentarismo y descanso nocturno). Encontramos diferencias significativas entre chicas y chicos para las variables de calidad y frecuencia alimentarias, actividad física, sedentarismo, flexibilidad y consumo máximo de oxígeno. En el análisis predictivo, los modelos predijeron significativamente el IMC de la muestra total, del grupo de chicos y del grupo de chicas, siendo las variables explicativas la calidad del desayuno, el sedentarismo de pantalla, el VO2 máxy la agilidad.

          Abstract Obesity has become one of the most serious health problems in our society and is associated with a multitude of conditions and complications at puberty. Through this descriptive, cross-sectional study we intended, first, to know the differences by gender in lifestyle and physical condition variables, and second, to know the determinants related to lifestyle and physical condition for a Spanish population aged 10 to 12 years with a medium socioeconomic status. The variables analyzed were BMI, physical condition variables (agility, flexibility, and cardiorespiratory capacity), and health habit variables (quality and frequency of food, physical activity, sedentary lifestyle, and sleep duration). We found significant differences between girls and boys in food quality and frequency, physical activity, sedentary lifestyle, flexibility, and maximum oxygen consumption variables. In the predictive analysis, the models significantly predicted the BMI for the total sample, the group of boys, and the group of girls. Explanatory variables include quality of breakfast, sedentary lifestyle, VO2 maxand agility.

          Early life risk factors for obesity in childhood: cohort study.

          To identify risk factors in early life (up to 3 years of age) for obesity in children in the United Kingdom. Prospective cohort study. Avon longitudinal study of parents and children, United Kingdom. 8234 children in cohort aged 7 years and a subsample of 909 children (children in focus) with data on additional early growth related risk factors for obesity. Obesity at age 7 years, defined as a body mass index (3) 95th centile relative to reference data for the UK population in 1990. Eight of 25 putative risk factors were associated with a risk of obesity in the final models: parental obesity (both parents: adjusted odds ratio, 10.44, 95% confidence interval 5.11 to 21.32), very early (by 43 months) body mass index or adiposity rebound (15.00, 5.32 to 42.30), more than eight hours spent watching television per week at age 3 years (1.55, 1.13 to 2.12), catch-up growth (2.60, 1.09 to 6.16), standard deviation score for weight at age 8 months (3.13, 1.43 to 6.85) and 18 months (2.65, 1.25 to 5.59); weight gain in first year (1.06, 1.02 to 1.10 per 100 g increase); birth weight, per 100 g (1.05, 1.03 to 1.07); and short (< 10.5 hours) sleep duration at age 3 years (1.45, 1.10 to 1.89). Eight factors in early life are associated with an increased risk of obesity in childhood.

            Predictive validity of health-related fitness in youth: a systematic review.

            The objective of the present systematic review was to investigate whether physical fitness in childhood and adolescence is a predictor of cardiovascular disease (CVD) risk factors, events and syndromes, quality of life and low back pain later in life. Physical fitness-related components were: cardiorespiratory fitness, musculoskeletal fitness, motor fitness and body composition. Adiposity was considered as both exposure and outcome. The results of 42 studies reporting the predictive validity of health-related physical fitness for CVD risk factors, events and syndromes as well as the results of five studies reporting the predictive validity of physical fitness for low back pain in children and adolescents were summarised. Strong evidence was found indicating that higher levels of cardiorespiratory fitness in childhood and adolescence are associated with a healthier cardiovascular profile later in life. Muscular strength improvements from childhood to adolescence are negatively associated with changes in overall adiposity. A healthier body composition in childhood and adolescence is associated with a healthier cardiovascular profile later in life and with a lower risk of death. The evidence was moderate for the association between changes in cardiorespiratory fitness and CVD risk factors, and between cardiorespiratory fitness and the risk of developing the metabolic syndrome and arterial stiffness. Moderate evidence on the lack of a relationship between body composition and low back pain was found. Due to a limited number of studies, inconclusive evidence emerged for a relationship between muscular strength or motor fitness and CVD risk factors, and between flexibility and low back pain.

              Early markers of adult obesity: a review

              Summary The purpose of this review was to evaluate factors in early childhood (≤5 years of age) that are the most significant predictors of the development of obesity in adulthood. Factors of interest included exposures/insults in the prenatal period, infancy and early childhood, as well as other socio-demographic variables such as socioeconomic status (SES) or birth place that could impact all three time periods. An extensive electronic and systematic search initially resulted in 8,880 citations, after duplicates were removed. Specific inclusion and exclusion criteria were set, and following two screening processes, 135 studies were retained for detailed abstraction and analysis. A total of 42 variables were associated with obesity in adulthood; however, of these, only seven variables may be considered as potential early markers of obesity based on the reported associations. Possible early markers of obesity included maternal smoking and maternal weight gain during pregnancy. Probable early markers of obesity included maternal body mass index, childhood growth patterns (early rapid growth and early adiposity rebound), childhood obesity and father's employment (a proxy measure for SES in many studies). Health promotion programmes/agencies should consider these factors as reasonable targets to reduce the risk of adult obesity.
