Television viewing time and risk of incident obesity and central obesity: the English longitudinal study of ageing

摘要

BackgroundResearch suggests television viewing time may be associated with incident obesity and central obesity in young adults. No study has investigated these associations in older English adults.The aim of this study was to investigate longitudinal associations between television viewing time and incident obesity and central obesity in a sample of older English adults.Analyses of data from the English Longitudinal Study of Ageing. At baseline (2008), participants reported their television viewing time. Research nurses recorded obesity and central obesity by body mass index and waist circumference, respectively, at four year follow-up. Associations between television viewing time and incident obesity (BMI > 30 kg/m²) and central obesity (waist >102 cm men; > 88 cm women) at four year follow-up were examined using adjusted logistic regression. Participants gave full written informed consent to participate in the study and ethical approval was obtained from the London Multicentre Research Ethics Committee.
