Last Wednesday I referred to a systematic review in the Britisch Medical Journal showing that well-planned intervention to promote walking can indeed encourage people to walk an extra 30-60 minutes per week. A study published in the Journal of the American Medical Association (JAMA; see http://jama.ama-assn.org/) shows that using step counters to self monitor walking activity encourages people to walk more. The authors, Bravata and colleagues, reviewed 26 original studies and their review indicates that using step counters on average leads to an extra 2000 steps per day (15-20 minutes walking). This extra activity was associated with a few kilo's less body weight and a lower blood pressure. See http://jama.ama-assn.org/cgi/content/short/298/19/2296 for an abstract of the review study.
