Abstract

Objective: Sleep duration is associated with obesity and cardiometabolic disease. It is unclear, though, how these relationship differs across age groups. Methods: Data from 2007 to 2008 National Health and Nutrition Examination Survey (NHANES) were used, including respondents aged 16+ with complete data (N = 5,607). Sleep duration and age were evaluated by self‐report, and body mass index (BMI) was assessed objectively. Sleep duration was evaluated continuously and categorically [very short (≤4 h), short (5‐6 h), and long (≥9 h) versus average (7‐8 h)]. Age was also evaluated continuously and categorically [adolescent (16‐17 years), young adult (18‐29 years), early middle age (30‐49 years), late middle age (50‐64 years), and older adult (≥65 years)]. Results: There was a significant interaction with age for both continuous (Pinteraction = 0.014) and categorical (Pinteraction = 0.035) sleep duration. A pseudo‐linear relationship was seen among the youngest respondents, with the highest BMI associated with the shortest sleepers and the lowest BMI associated with the longest sleepers. This relationship became U‐shaped in middle‐age, and less of a relationship was seen among the oldest respondents. Conclusions: These findings may provide insights for clinical recommendations and could help to guide mechanistic research regarding the sleep‐obesity relationship.

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

  • In 2007-2008 NHANES, the relation between sleep duration and obesity depends on age, being stronger among younger than older adults.

    “Specifically, the relation between SSD and obesity is stronger among younger than among older adults.40”
  • The relationship between sleep duration and obesity is dependent on age, with strongest relationships among younger adults and U-shaped relationships more common in middle-aged adults.

    “First, this relationship is dependent on age, with the strongest relationships among younger adults and U-shaped relationships more common in middle-aged adults.47”

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.
