Abstract

Physical activity (PA) has numerous health benefits, particularly for those with diabetes. However, rates of long-term PA participation are often poor. PURPOSE: This study examined the effect of an intensive lifestyle intervention (ILI) on objectively assessed PA for a 4-yr period among older adults with type 2 diabetes. METHODS: Data from 2400 participants (age = 59.3 ± 6.9 yr, body mass index = 36.1 ± 5.9 kg·m) with accelerometry data from the Look AHEAD trial were included in the analyses. Participants randomized to ILI were instructed to reduce caloric intake and progress to ≥175 min·wk of moderate-to-vigorous-intensity PA (MVPA), whereas those randomized to Diabetes Support and Education (DSE) served as the control group. PA was measured at baseline, year 1, and year 4 using an RT3 accelerometer, and bout-related MVPA (PA ≥3 METs, accumulated in bouts of ≥10 min in duration) was calculated. RESULTS: Despite no differences at baseline (ILI = 93.4 ± 152.7 vs DSE = 88.4 ± 143.6 min·wk), bout-related MVPA was significantly greater in ILI compared with DSE at year 1 (151.0 ± 213.5 vs 87.5 ± 145.1 min·wk, P < 0.0001) and year 4 (102.9 ± 195.6 vs 73.9 ± 267.5 min·wk, P < 0.001), and more ILI participants achieved ≥175 min·wk at year 1 (29.1% vs 16.3%, P < 0.001) and year 4 (18.3% vs 10.0%, P < 0.001). Forty-one percent of ILI participants who achieved ≥175 min·wk at year 1 maintained this threshold of PA at year 4. However, the majority of ILI participants never achieved the ≥175 min·wk threshold. CONCLUSIONS: When measured objectively and compared with DSE, ILI engaged in significantly more bout-related MVPA for a 4-yr period. However, future intervention strategies should target the large percentage of individuals who fail to reach the MVPA goal as result of a lifestyle intervention.

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.
