    Background and objectives: The effectiveness of short-term focused educational programs to change health behaviors across large populations seems to be poorly described so far. The main aim of the present study was to evaluate an age-specific 45-min educational program, designed in accordance with the current U.S. Department of Health and Human Services and U.S. Department of Agriculture dietary guidelines and physical activity (PA) guidelines, among adolescents and adults. Materials and Methods: We evaluated the health-promoting lifestyle habits by the Health-Promoting Lifestyle Profile (HPLP-II) at baseline and following 6–8 weeks post-education in a nationally representative sample of Serbian adolescents and adults (n = 3822). Results: The percentage of adolescents eating 3–5 servings of vegetables per day increased at follow-up (20.1% versus 23.1%, p = 0.001), with significantly more adolescents regularly reading food labels (from 12.2% at baseline to 14.2% at follow-up; p = 0.02). Taken together, mean HPLP-II scores in adolescents significantly improved for both diet (0.05 points; p < 0.0001) and PA (0.09 points; p < 0.0001), and for PA in adults (0.08 points; p < 0.0001). Hierarchical multiple regression analysis revealed that our model as a whole (including time of testing as a predictor variable, and age and gender as control variables) explained 3.0% of the variance in mean HPLP-II scores for diet (p = 0.942) and 3.0% for PA (p = 0.285) in adolescents, and 1.1% of the variance in HPLP-II scores for diet (p = 0.781) and 1.9% for PA (p = 0.075) in adults, respectively. Conclusions: It appears that a brief focused education can positively tackle unhealthy lifestyles in promoting good health in general population. Different modes of interactive communication used here appeared to strengthen participants’ capacities for lifestyle changes. © 2019 by the authors. Licensee MDPI, Basel, Switzerland.

    Introduction: Introduction: based on the presumed relationship between physical activity and physical fitness, it seems reasonable to expect that being active would result in sufficient fitness levels. However, the relationship between physical activity and fitness is not so plausible and needs deeper exploration. Objectives: we conducted a study aimed at exploring: a) the potential variation in physical activity level by gender and school grade; and b) the effect of physical activity level, gender, and nutritional status on physical fitness test results. Methods: a total of 2795 males and 2614 females participated in the study (11-14 years). Their physical fitness was assessed by measuring anthropometric status, muscular fitness, endurance, flexibility, agility, and cardiorespiratory fitness, while their physical activity was assessed using the Physical Activity Questionnaire (PAQ-A). Results: a higher percentage of boys were highly active, while a higher percentage of girls were scarcely active (χ2 [2, n = 5017] = 151.4, p < 0.01). Decline in physical activity with age was higher in girls than in boys (χ2 [6, n = 5409] = 90.4, p < 0.01). MANOVA revealed a significant effect of gender (V = 0.009, F [6, 3669] = 5.29, p < 0.01), nutritional status (V = 0.193, F [12, 7340] = 65.16, p < 0.01) and physical activity levels (V = 0.043, F [12, 7340] = 13.60, p < 0.01) on tests outcomes. Conclusions: our study has shown that activity level in Serbian schoolchildren declines with age and is affected by nutritional status. Nutritional status represents a significant factor confounding physical fitness scores, regardless of activity levels.; Introducción: Introducción: basado en la presumible relación entre la actividad física y la condición física, parece razonable esperar que ser activo físicamente resulte en niveles suficientes de condición física. Sin embargo, la relación entre la actividad física y la forma física no es tan plausible y necesita una exploración más profunda. Objetivos: realizamos un estudio con el objetivo de explorar: a) la variación potencial en el nivel de actividad física en función del género y el grado escolar; y b) el efecto del nivel de actividad física, el género y el estado nutricional en el resultado de las pruebas de condición física. Métodos: un total de 2795 hombres y 2614 mujeres participaron en el estudio (11-14 años). Su condición física se evaluó midiendo el estado antropométrico, la aptitud muscular, la resistencia, la flexibilidad, la agilidad y la aptitud cardiorrespiratoria, mientras que la actividad física se evaluó mediante el Cuestionario de Actividad Física (PAQ-A). Resultados: un mayor porcentaje de niños eran muy activos, mientras que un mayor porcentaje de niñas eran poco activas (χ2 [2, n = 5017] = 151,4, p < 0,01). La disminución de la actividad física con el incremento de la edad fue mayor en las niñas que en los niños (χ2 [6, n = 5409] = 90,4, p < 0,01). El MANOVA reveló un efecto significativo del género (V = 0.009, F [6, 3669] = 5.29, p < 0.01), el estado nutricional (V = 0.193, F [12, 7340] = 65.16, p < 0.01) y los niveles de actividad física (V = 0.043, F [12, 7340] = 13.60, p < 0.01) en los resultados de las pruebas. Conclusiones: nuestro estudio ha demostrado que el nivel de actividad física en los escolares serbios disminuye con la edad y se ve afectado por el estado nutricional. El estado nutricional representa un factor significativo que confunde las puntuaciones de condición física, independientemente de los niveles de actividad.
