BACKGROUND The World Health Organization ( WHO ) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese .
In addition , WHO estimates that physical inactivity causes 10 % to 16 % of cases each of breast cancer , colon , and rectal cancers as well as type 2 diabetes , and 22 % of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades .
OBJECTIVES The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents .
Influence of a lifestyle intervention in preschool children on physiological and psychological parameters (Ballabeina): study design of a cluster randomized controlled trial
Background Childhood obesity and physical inactivity are increasing dramatically worldwide . Children of low socioeconomic status and /or children of migrant background are especially at risk . In general , the overall effectiveness of school-based programs on health-related outcomes has been disappointing . A special gap exists for younger children and in high risk groups . Methods / Design This paper describes the rationale , design , curriculum , and evaluation of a multicenter preschool r and omized intervention study conducted in areas with a high migrant population in two out of 26 Swiss cantons . Twenty preschool classes in the German ( canton St. Gallen ) and another 20 in the French ( canton Vaud ) part of Switzerl and were separately selected and r and omized to an intervention and a control arm by the use of opaque envelopes . The multidisciplinary lifestyle intervention aim ed to increase physical activity and sleep duration , to reinforce healthy nutrition and eating behaviour , and to reduce media use . According to the ecological model , it included children , their parents and the teachers . The regular teachers performed the majority of the intervention and were supported by a local health promoter . The intervention included physical activity lessons , adaptation of the built infrastructure ; promotion of regional extracurricular physical activity ; playful lessons about nutrition , media use and sleep , funny homework cards and information material s for teachers and parents . It lasted one school year . Baseline and post-intervention evaluations were performed in both arms . Primary outcome measures included BMI and aerobic fitness ( 20 m shuttle run test ) . Secondary outcomes included total ( skinfolds , bioelectrical impedance ) and central ( waist circumference ) body fat , motor abilities ( obstacle course , static and dynamic balance ) , physical activity and sleep duration ( accelerometry and question naires ) , nutritional behaviour and food intake , media use , quality of life and signs of hyperactivity ( question naires ) , attention and spatial working memory ability ( two vali date d tests ) . Research ers were blinded to group allocation . Discussion The purpose of this paper is to outline the design of a school-based multicenter cluster r and omized , controlled trial aim ing to reduce body mass index and to increase aerobic fitness in preschool children in culturally different parts of Switzerl and with a high migrant population .Trial Registration Trial Registration : clinical trials.gov
