ABSTRACT
La evaluación de los componentes del estilo de vida de los humanos en particular, del consumo de bebidas y alimentos y la actividad física resulta crucial en el entendimiento del bienestar y la calidad de vida de los individuos. Con el objetivo de actualizar esta información en Latinoamérica, se realizó un estudio transversal denominado Estudio Latinoamericano de Nutrición y Salud (ELANS), mediante muestreo aleatorio, polietápico por cuotas y estandarización metodológica para recopilar información sobre consumo de alimentos y bebidas, actividad física y antropometría. Se utilizó Recordatorio 24 horas, IPAQ largo, acelerometría, y obtención de peso, talla, circunferencias de cuello, cintura y cadera según las recomendaciones técnicas de OMS en Argentina, Brasil, Chile, Colombia, Costa Rica, Ecuador, Perú y Venezuela en una muestra de 9000 individuos. La muestra en Venezuela fue de 1132, distribuida por regiones, estrato social, edad y sexo, que se calculó según el censo 2011. Entre las fortalezas del estudio destacan, la representatividad por país, la estandarización metodológica entre los países participantes y el aporte de información actualizada sobre consumo de alimentos y bebidas, actividad física y gasto energético para los países que no lo tienen. ELANS y el Estudio Venezolano de Nutrición y Salud (EVANS) representan estudios de características particulares tanto en el ámbito regional como local que deben servir de bases para el diseño de políticas públicas basadas en evidencias(AU)
The evaluation of human lifestyle components particularly, the consumption of foods and beverages and physical activity is key in understanding the well-being and quality of life of individuals. With the objective of updating this information in Latin America, a cross-sectional study (called The Latin American Study of Nutrition and Health ELANS) was carried out. A random complex multistage sampling of 9000 adolescents and adults stratified by geographical region, age, sex and socioeconomic status was performed. A methodological standardization was required to collect information on food and beverage consumption, physical activity and anthropometry using methods: 24-hour recall, IPAQ long, accelerometry, and weight, height, neck, waist and hip circumferences according to WHO technical recommendations in subjects belonging to the following countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru and Venezuela. The representative sample for Venezuela was 1132 subjects distributed by regions and quotas assigned by social stratification, age and sex, calculated according to data from the 2011 census. Strengths of the study include: representativeness by country, methodological standardization among participating countries and the contribution of updated information on consumption of food and beverages, physical activity and energy expenditure for countries that do not have it. ELANS and the Venezuelan Study of Nutrition and Health (EVANS) represent a study of unique characteristics at both regional and local levels that should serve as the basis for the design of evidence-based public policies(AU)

Objetivo: avaliar cefalometricamente a influência do Bionatorde Balters no plano oclusal em pacientes dolicofaciais portadoresde maloclusão de Classe II de Angle associadas ao retrognatismomandibular, durante a fase de crescimento. Metodologia:a amostra consistiu de 40 telerradiografias obtidas em doistempos (T1: inicial; T2: após bionatorterapia) de 20 pacientes,sendo 10 do sexo masculino e 10 do sexo feminino com idadesvariando entre 7 e 15 anos (média de 9,03). Resultados e Conclusões:constatou-se um controle bastante eficiente da inclinaçãodo plano oclusal, provocando sua rotação anti-horária, o que éconsiderado essencial na estabilidade dos resultados.
Aim: the purpose of this study is a cephalometric evaluationof the influence of the Balters Bionator on the occlusal plane indolichofacial patients with mandibular Class II malocclusionduring growth period. Methods: the sample comprised of 40 lateralcephalograms taken at two times (T1: initial; T2: after bionatortherapy)from 20 patients, 10 females and 10 males withage ranging between 7 and 15 years (average 9,03). Results andconclusions: an efficient control of the occlusal plane inclinationwas evidenced resulting counter clockwise rotation which wasessential for the achievement and stability of the results.
