Abstract

STUDY OBJECTIVES: To examine whether the initial benefit of weight loss on obstructive sleep apnea (OSA) severity at 1 year is maintained at 4 years. DESIGN: Randomized controlled trial with follow-up at 1, 2, and 4 years. SETTING: 4 Look AHEAD clinical centers. PARTICIPANTS: Two hundred sixty-four obese adults with type 2 diabetes and OSA. INTERVENTIONS: Intensive lifestyle intervention with a behavioral weight loss program or diabetes support and education. MEASUREMENTS: Change in apnea-hypopnea index on polysomnogram. RESULTS: The intensive lifestyle intervention group's mean weight loss was 10.7 ± 0.7 (standard error), 7.4 ± 0.7, and 5.2 ± 0.7 kg at 1, 2, and 4 years respectively, compared to a less than 1-kg weight loss for the control group at each time (P < 0.001). Apnea-hypopnea index difference between groups was 9.7 ± 2.0, 8.0 ± 2.0, and 7.7 ± 2.3 events/h at 1, 2 and 4 years respectively (P < 0.001). Change in apnea-hypopnea index over time was related to the amount of weight loss (P < 0.0001) and intervention, independent of weight loss (P = 0.001). Remission of OSA at 4 years was 5 times more common with intensive lifestyle intervention (20.7%) than diabetes support and education (3.6%). CONCLUSIONS: Among obese adults with type 2 diabetes and OSA, intensive lifestyle intervention produced greater reductions in weight and apnea-hypopnea index over a 4 year period than did diabetes support and education. Beneficial effects of intensive lifestyle intervention on apneahypopnea index at 1 year persisted at 4 years, despite an almost 50% weight regain. Effect of intensive lifestyle intervention on apnea-hypopnea index was largely, but not entirely, due to weight loss.

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

  • Longer maintenance of weight loss might further reduce the risk of type 2 diabetes in at-risk people and preserve gains in sleep apnea, physical mobility, and other conditions improved by weight loss.

    “Sustaining weight loss for longer periods may further improve the prevention of type 2 diabetes in at-risk individuals,34 as well as maintain improvements in sleep apnea,5 physical mobility,6 and other health conditions ameliorated by weight loss.7–9”
  • In South Asian, Southeast Asian, and East Asian adults, waist circumference ≥85 cm in men and ≥74 cm in women indicate excess abdominal fat.

    Table 1 reports participants’ mean waist circumference, and the Discussion considers changes in waist circumference as a measure of central adiposity. Neither gives thresholds for excess abdominal fat in South Asian, Southeast Asian, or East Asian adults. Searches for the 85 cm and 74 cm cutoffs and Asian-specific waist criteria found no supporting passage in our copy. (LLM, conf=0.77)

  • Waist circumference cutoff points for increased cardiometabolic disease risk are ≥102 cm for men and ≥88 cm for women in the United States and Canada, and ≥94 cm for men and ≥80 cm for women in many other populations.

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.
