Abstract

Objectives The aim was to examine the independent and joint associations of sitting time and physical activity with risk of incident cardiovascular disease (CVD). Background Sedentary behavior is recognized as a distinct construct beyond lack of leisure-time physical activity, but limited data exists on the interrelationship between these two components of energy balance. Methods Participants in the prospective Women’s Health Initiative Observational Study (N = 71,018), aged 50–79 and free of CVD at baseline (1993–1998), provided information on sedentary behavior, defined as hours of sitting per day, and usual physical activity at baseline and during follow-up through September 2010. First CVD (coronary heart disease or stroke) events were centrally adjudicated. Results Sitting ≥ 10 hours/day compared to ≤ 5 hours/day was associated with increased CVD risk (HR=1.18, 95% CI 1.09, 1.29) in multivariable models including physical activity. Low physical activity was also associated with higher CVD risk (P, trend <0.001). When women were cross-classified by sitting time and physical activity (P, interaction = 0.94), CVD risk was highest in inactive women (≤1.7 MET-hrs/week) who also reported ≥10 hrs/day of sitting. Results were similar for CHD and stroke when examined separately. Associations between prolonged sitting and risk of CVD were stronger in overweight versus normal weight women and women aged 70 years and older compared to younger women. Conclusions Prolonged sitting time was associated with increased CVD risk, independent of leisure-time physical activity, in postmenopausal women without a history of CVD. A combination of low physical activity and prolonged sitting augments CVD risk.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Five included studies specifically investigated occupational-related physical activity or commuting activity, either as the primary objective or in addition to leisure time activity.

    “five studies specifically investigated occupational-related physical activity or commuting activity,32,35,48,50,60 either as the primary objective or in addition to investigating leisure time activity.”

    From Sex Differences in Physical Activity and Incident Stroke: A Systematic Review (2022) · cites this paper as [35]

    The Methods (Exposure Assessment; page unavailable) specify that the physical-activity measure was leisure-time activity. The Discussion (page unavailable) says the study could not examine transportation separately because its questionnaire measured only total sitting time. Thus, this paper did not specifically investigate occupational or commuting physical activity as the citing sentence claims. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Eight studies (29%) reported a non-significant association between physical activity and incident total stroke in women.

    “and eight (29%) reported a non-significant association between physical activity and incident total stroke.30,33,35,41,56,62,64,65”

    From Sex Differences in Physical Activity and Incident Stroke: A Systematic Review (2022) · cites this paper as [35]

    The Results section reports that decreased physical activity was associated with increased stroke risk in the women studied and says the associations remained statistically significant after further adjustment (Table 2). That contradicts describing this study as reporting a non-significant physical-activity–stroke association. The eight-study count and 29% are claims about the citing paper’s collection of studies, not findings this source can establish. (LLM, conf=0.87)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Among those 17 papers, 3 (18%) showed a significant effect of physical activity on total stroke in men but not in women.

    “3 (18%) of studies showed a significant effect in men but not in women”

    From Sex Differences in Physical Activity and Incident Stroke: A Systematic Review (2022) · cites this paper as [35]

    The Methods (Study Population; page unavailable) describe an analysis of 71,018 women, and the Discussion says its findings cannot necessarily be generalized to men. The Results report stroke outcomes in that cohort, but our copy provides no tally of 17 papers or finding that three showed a significant effect in men but not women (searched for the 3/17 figure and sex differences in stroke). (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • Ten or more hours of sitting per day increased cardiovascular disease risk by 18% (HR=1.18; 95% CI 1.09-1.29) compared to five or fewer hours.

    “For example, ten or more hours of sitting per day increased cardiovascular diseases risk by 18 % (Hazard ratio = 1.18; 95% CI = 1.09–1.29) as compared to five or fewer hours [73]”

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.
