Abstract

OBJECTIVE: To assess the relationship between obesity and sedentary behaviours, such as watching television or using a computer ('screen-time'), and describe how this relationship varies between population subgroups. DESIGN: Cross-sectional analysis of the relationship between obesity (BMI ≥ 30 kg/m2) and screen-time, adjusted for age, sex, income and education and compared according to a range of personal characteristics. SETTING: New South Wales, Australia. SUBJECTS: A total of 91 266 men and women aged 45 years and above from the general population of New South Wales in 2006-2007 and providing self-reported information on height and weight and other factors. RESULTS: Obesity prevalence was 21.4 %. Compared to individuals with <2 h of daily screen-time, the adjusted relative risks (RR) of obesity were 1.35 (95 % CI 1.26, 1.44), 1.70 (95 % CI 1.59, 1.82), 1.94 (95 % CI 1.81, 2.08) and 1.92 (95 % CI 1.80, 2.06) for 2-3, 4-5, 6-7 and ≥8 h, respectively. The increase in obesity with increasing screen-time was similar within categories of overall physical activity, but was attenuated in those in full-time paid work, compared to non-workers (P for interaction < 0.0001). Among non-workers, the overall obesity RR per 2 h increase in daily screen-time was 1.23 (95 % CI 1.21, 1.25) and was significantly elevated in all groups examined, ranging from 1.16 to 1.31 according to sex, level of age, education, income, smoking and fruit consumption. The RR did not differ significantly according to overall physical activity, region of residence and alcohol and vegetable consumption, but was substantially lower in disabled v. not-disabled individuals (P for interaction < 0.0001). CONCLUSIONS: Obesity increases with increasing screen-time, independent of purposeful physical activity. This was observed in all population groups examined, although it is attenuated in full-time workers and disabled individuals.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
