AbstractObjectiveTo examine the association between breakfast consumption and CVD risk factors in European adolescents.DesignCross-sectional. Breakfast consumption was assessed by the statement ‘I often skip breakfast’ and categorized into ‘consumer’, ‘occasional consumer’ and ‘skipper’. Blood pressure, weight, height, waist circumference, skinfold thickness, total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C), TAG, insulin and glucose were measured and BMI, TC:HDL-C, LDL-C:HDL-C and homeostasis model assessment–insulin resistance index (HOMA-IR) were calculated.SettingThe European Union-funded HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) Study.SubjectsEuropean adolescents, aged 12·50–17·49 years, from ten cities within the HELENA study (n2929,n925 with blood sample, 53 % females).ResultsIn males, significant differences across breakfast consumption category (‘consumer’, ‘occasional consumer’ and ‘skipper’) were seen for age, BMI, skinfold thickness, waist circumference, cardiorespiratory fitness, systolic and diastolic blood pressures, TC:HDL-C, LDL-C:HDL-C, glucose, insulin, HOMA-IR and LDL-C; in females, for cardiorespiratory fitness, skinfold thickness, BMI, insulin and HOMA-IR. In overweight/obese males significant differences were also seen for TC and LDL-C, whereas no differences were observed in non-overweight males or in females regardless of weight status.ConclusionsOur findings among European adolescents confirm previous data indicating that adolescents who regularly consume breakfast have lower body fat content. The results also show that regular breakfast consumption is associated with higher cardiorespiratory fitness in adolescents, and with a healthier cardiovascular profile, especially in males. Eating breakfast regularly may also negate somewhat the effect of excess adiposity on TC and LDL-C, especially in male adolescents.

“…To the contrary, the on-site fitness tests are easy to be administered, include minimal equipment, may test a large number of respondents and may be evaluated in a short period of time [11][12][13]. In the school environment the onsite tests are economical and practical options for assessment of the level of physical fitness of the scholars.…”

Background: This is the first study to publish the normative reference values for assessment of the level of muscular strength through the "standing long jump" test carried out on a large sample of Macedonian school children. The normative values encompass a wide span of years (6 -18). Methods: The research was realized in a large sample of 12618 school children at the age of 6 to 18 years from Macedonia. The sample was divided in 14 groups, according to chronological age and each age group was divided into two subgroups according to the criteria of gender. For estimation of the morphologic characteristics, the following anthropometric measures have been applied: body height in standing position (cm), body weight (kg), as well as the body mass index (BMI). Children aged 6 or above were invited to take a standing long jump test. Results: Boys show statistically better results in all age categories in the standing long jump test than girls, and these differences become bigger with the increase of age, especially after the 14th year (p < 0.000). Results from the linear regressive analysis show that the constants in predicting the standing long jump are similar both in boys and in girls. However, the age coefficient in boys is two times higher than that in girls. The Body Mass Index, as a factor, influences two times more in boys in predicting the standing long jump, which indicates that the body size in boys has bigger inverse impacts on the results of the standing long jump than that in girls. Conclusion: Normative reference values shall provide proper assessment and interpretation of the level of muscular strength of the Macedonian school children in terms of the age and gender, accurate detection of progress of an individual as well as undertaking preventive measures and level of intervention.

Los autores declaran que no existen conflictos de interés. RESUMENFundamentos: La evaluación del VO 2max permite clasificar a los sujetos según el riesgo para la salud. Sin embargo los factores que pueden afectar a las clasificaciones han sido poco estudiados. El objetivo de esta investigación fue determinar si el tipo de ecuación predictiva del VO 2max y los criterios de referencia del Fitnessgram ® modifican la proporción de adultos jóvenes clasificados con un nivel de capacidad aeró-bica indicativo de riesgo cardiometabólico. Métodos:El diseño del estudio fue observacional, relacional y de corte transversal. Participaron voluntariamente 240 adultos jóvenes. El VO 2max fue estimado mediante el test de Course Navette aplicando 9 ecuaciones predictivas. Las diferencias en las clasificaciones fueron analizadas con la prueba Q de Cochran y la de MacNemar.Resultados: El nivel de capacidad aeróbica indicativo de riesgo cardiometabólico osciló entre 7,1% y 70,4% según el tipo de ecuación predictiva y el criterio de referencia utilizado (p<0,001). Independientemente del la ecuación predictiva del VO 2max y el criterio de referencia aplicado; una mayor proporción de mujeres, del 29,4% al 85,3%, fueron clasificadas con un nivel no saludable de capacidad aeróbica frente al 4,8% a 51% en varones (p<0,001). En ambos sexos, los viejos criterios de referencia clasificaron a una menor proporción de hombres (del 4,8% al 48,1%) y mujeres (del 39,4% al 68,4%) con capacidad aeróbica no saludable, independientemente de la ecuación aplicada (p<0,001).Conclusiones: El tipo de ecuación predictiva del VO 2max y los criterios de referencia del Fitnessgram ® modifican las clasificaciones de adultos jóvenes con un nivel de capacidad aeróbica saludable o de riesgo cardiometabólico.Palabras clave: Consumo de oxígeno.

ABSTRACT Cardiorespiratory Fitness and Cardiometabolic Risk in Young AdultsBackground: The assessment of VO 2max allow classify subjects according to the health risk. However the factors that may affect the classifications have been little studied. The main purpose was to determine whether the type of VO 2max prediction equation and the Fitnessgram ® criterion-referenced standards modified the proportion of young adults classified with a level of aerobic capacity cardiometabolic risk indicative.
