OBJECTIVE At 5 to 6 years of age, body fatness normally declines to a minimum, a point called adiposity rebound (AR), before increasing again into adulthood. We determined whether a younger age at AR was associated with an increased risk of adult obesity and whether this risk was independent of fatness at AR and parent obesity. DESIGN A retrospective cohort study using lifelong height and wei...

BACKGROUND Influenza causes substantial morbidity and mortality worldwide, yet few data exist on influenza infection rates in tropical, developing countries. In 2011, we established the Nicaraguan Pediatric Influenza Cohort Study (NPICS) to study the burden and seasonality of influenza in Nicaraguan children. Here we describe the study design, methods, and participation data of the NPICS for 20...

Professors Greenwald and Oyakawa 2017-04-19 In these notes, we improve on the basic expert advice algorithms previously introduced. The basis for this technique is that we give each expert a weight, which influences how much sway she has in the algorithm’s decision. An expert who is wrong will frequently have her weight reduced and will therefore have less of an impact on the algorithm’s decisi...

In this lecture, we will study various applications of the theory of Multiplicative Weights (MW). In this section, we briefly review the general version of the MW algorithm that we studied in the previous lecture. The following sections then show how the theory can be applied to approximately solve zero-sum games and linear programs, and how it connects with the theory of boosting and approxima...

OBJECTIVE The aim of the present study was to determine physical activity (PA) and nutrition knowledge and preferences in low socio-economic status kindergarten children. METHODS Following height and weight measurement, 795 low socio-economic status kindergarten children (age 3.8-6.8 y.o) completed a photo-pair knowledge and preferences food and exercise questionnaire. RESULTS No difference...
