Abstract

The obesity epidemic is attributed in part to reduced physical activity. Evidence supports that reducing time spent sitting, regardless of activity, may improve the metabolic consequences of obesity. Analyses were conducted in a large prospective study of US adults enrolled by the American Cancer Society to examine leisure time spent sitting and physical activity in relation to mortality. Time spent sitting and physical activity were queried by questionnaire on 53,440 men and 69,776 women who were disease free at enrollment. The authors identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up. After adjustment for smoking, body mass index, and other factors, time spent sitting (> or = 6 vs. <3 hours/day) was associated with mortality in both women (relative risk = 1.34, 95% confidence interval (CI): 1.25, 1.44) and men (relative risk = 1.17, 95% CI: 1.11, 1.24). Relative risks for sitting (> or = 6 hours/day) and physical activity (<24.5 metabolic equivalent (MET)-hours/week) combined were 1.94 (95% CI: 1.70, 2.20) for women and 1.48 (95% CI: 1.33, 1.65) for men, compared with those with the least time sitting and most activity. Associations were strongest for cardiovascular disease mortality. The time spent sitting was independently associated with total mortality, regardless of physical activity level. Public health messages should include both being physically active and reducing time spent sitting.

  • Patel et al. reported that 54.1% of older adults reported leisure-time sitting for over 3 h per day.

    “Patel et al. [15] using ACS II NC data, reported “leisure time sitting” and reported a level of 54.1% reporting over 3 h at this level, compared to 78.0% “total sitting time” found by the meta-prevalence method.”
  • Katzmarzyk and Lee could not assess dose-response relationships between total sitting time and mortality because the included studies used qualitative categorical or leisure-time sitting measures.

    “One study in this meta-analysis used a qualitative categorical measure of daily sitting (none of the time, 1/4 of the time, ½ the time, three-quarters of the time, all of the time)[16] while the other study measured daily leisure-time sitting[17]. Therefore, the authors could not assess dose-response relationships between total sitting time and mortality.”

    From Daily Sitting Time and All-Cause Mortality: A Meta-Analysis (2013) · cites this paper as [17]

  • Self-reported sedentary time is positively associated with mortality.

    “Previous studies have shown self-reported sedentary time to be associated with mortality”
  • In several studies, associations between sedentary behaviour and increased risks persisted even among persons active enough to meet physical activity recommendations.

    “In several studies, investigators reported on the persistence of these associations even among persons active enough to meet physical activity recommendations.[13-20]”

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.
