Where can they play? Outdoor spaces and physical activity among adolescents in U.S. urbanized areas
Open accessAbstract
Objective To estimate behavior-specific effects of several objectively measured outdoor spaces on different types of moderate to vigorous physical activity (MVPA) in a large, diverse sample of U.S. adolescents.Methods Using data from Wave I (1994-1995) of the National Longitudinal Study of Adolescent Health (U.S., n=10,359) and a linked geographic information system, we calculated percent greenspace coverage and distance to the nearest neighborhood and major parks. Using sex-stratified multivariable logistic regression, we modeled reported participation in wheel-based activities, active sports, exercise, and ≥ 5 MVPA bouts/week as a function of each outdoor space variable, controlling for individual- and neighborhood-level sociodemographics.Results Availability of major or neighborhood parks was associated with higher participation in active sports and, in females, wheel-based activity and reporting ≥ 5 MVPA bouts/week [OR (95% CI): up to 1.71 (1.29, 2.27)]. Greater greenspace coverage was associated with reporting ≥ 5 MVPA bouts/week in males and females [OR (95% CI): up to 1.62 (1.10, 2.39) for 10.1 to 20% versus ≤ 10% greenspace] and exercise participation in females [OR (95% CI): up to 1.73 (1.21, 2.49)].Conclusions Provision of outdoor spaces may promote different types of physical activities, with potentially greater benefits in female adolescents, who have particularly low physical activity levels.

Cross-sectional and longitudinal analyses from the National Longitudinal Study of Adolescent Health suggest some positive associations between green space coverage or availability of physical activity facilities and physical activity among US adolescents but with somewhat varying findings depending on environment measure, physical activity outcome, and sex.

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.
