|Abstract: ||Background: Research 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.
Results: A total of 3777 initially non-obese participants (aged 64.8 ± 8.6 yrs, 46.4% male) were included in the
analyses using BMI as an outcome and 2947 for the analyses using waist circumference. No significant associations
were found between television viewing time and incident obesity. A significant association was found between
watching ≥6 hrs/d of television (compared to <2 hrs/d) and central obesity (Odds Ratio 1.48; 95% confidence
interval 1.07 to 2.03) after adjustment for covariables including physical activity.
Conclusions: In this sample of older community dwelling English adults greater television viewing time was
associated with incident central obesity, but not total obesity when measured by BMI. Interventions to reduce the
incidence of central obesity in this age group that focus on reducing TV time, as well as targeting other health
behaviours (eg, increasing physical activity levels, improving dietary intake) might prove useful.|
