Building the pipeline: programs to introduce middle school, high school, medical, and veterinary students to careers in epidemiology and public health.

Purpose: This report describes Centers for Disease Control and Prevention programs that expose students to epidemiology and public health sciences (EPHS).

Methods: The Science Ambassador workshop targets middle and high school teachers and promotes teaching EPHS in the classroom. The National Science Olympiad Disease Detectives event is an extracurricular science competition for middle and high school students based on investigations of outbreaks and other public health problems.

Objectively-measured physical activity in children is influenced by social indicators rather than biological lifecourse factors: Evidence from a Brazilian cohort.

The aim of this study was to examine the longitudinal influences of early life social and biological indicators on objectively measured physical activity. All newborns in 2004 in the city of Pelotas, Southern Brazil were enrolled in a birth cohort study. At the age of 6years, a follow-up visit included objective assessment of overall physical activity (summarized in milli-g, 1mg=0.

Ten-year trends in total physical activity practice in Brazilian adults: 2002-2012.

Background: One-third of adults worldwide are physically inactive causing over 5.3 million deaths annually. Despite a growing focus on physical activity and health, population-based data on physical activity trends in low- and middle-income countries are still limited.

Effect on physical fitness of a 10-year physical activity intervention in primary health care settings.

Background: Interventions in primary health care settings have been effective in increasing physical fitness. In 2001, the Programa de Exercício Físico em Unidades de Saúde (Physical Exercise in Health Primary Care Program-PEHPCP) was launched in Rio Claro City, Brazil. The intervention consisted of biweekly, 60-minute group sessions in all primary health care settings in the city.

Energy expenditure compared to physical activity measured by accelerometry and self-report in adolescents: a validation study.

Background: Physical inactivity is responsible for 5.3 million deaths annually worldwide. To measure physical activity energy expenditure, the doubly labeled water (DLW) method is the gold standard.
