CalFitness Smartphone-Delivered Physical Activity Intervention With Messaging

2017-05-11 13:23:21 | BioPortfolio


The overall goal of this study is to test personalized mobile phone-based physical activity interventions among students at the University of California, Berkeley. Most physical fitness applications for smartphones and activity trackers use a constant goal for the number of steps each day. However, if the step goals are dynamically adjusted according to past behavior, then the corresponding goals may encourage individuals to increase their physical activity level. This study consists of a randomized controlled trial in which we are assessing the efficacy of four different algorithms for calculating personalized goals for the number of steps each day and for determining which motivational messages to send each day.

Medical and Biotech [MESH] Definitions

A cellular phone with advanced computing and connectivity capability built on an operating system.

The care of a fetus or newborn given before, during, and after delivery from the 28th week of gestation through the 7th day after delivery.

Delivery of the FETUS and PLACENTA under the care of an obstetrician or a health worker. Obstetric deliveries may involve physical, psychological, medical, or surgical interventions.

Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.
