Dataset Information

Sedentary Time and Physical Activity Across Occupational Classifications.

ABSTRACT:

Purpose

To examine differences in activity patterns across employment and occupational classifications.

Design

Cross-sectional.

Setting

A 2005-2006 Coronary Artery Risk Development in Young Adults (CARDIA) study.

Sample

Participants with valid accelerometry data (n = 2068).

Measures

Uniaxial accelerometry data (ActiGraph 7164), accumulated during waking hours, were summarized as mean activity counts (counts/min) and time spent (min/d) in long-bout sedentary (≥30 minutes, SED_≥30), short-bout sedentary (<30 minutes, SED_<30), light physical activity (LPA), short-bout moderate-to-vigorous physical activity (<10 minutes, MVPA_<10), and long-bout MVPA (≥10 minutes, MVPA_≥10) using Freedson cut-points. Employment status was self-reported as full time, part time, unemployed, keeping house, or raising children. Self-reported job duties were categorized into 23 major groups using the 2010 Standard Occupational Classification.

Analysis

Omnibus differences were analyzed using adjusted analysis of covariance and repeated after stratification by race (black/white) and sex (female/male).

Results

SED_≥30, SED_<30, LPA, and MVPA_<10 differed significantly by employment and occupational categories (P ≤ .05), while MVPA_≥10 did not (P ≥ .50). SED_≥30, SED_<30, and LPA differed by occupational classification in men, women, blacks, and whites (P < .05). Mean activity counts, MVPA_<10, and MVPA_≥10 were significantly different across occupational classifications in whites (P ≤ .05), but not in blacks (P > .05). Significant differences in mean activity counts and MVPA_<10 across occupational classifications were found in males (P ≤ .001), but not in females (P > .05).

Conclusion

Time within activity intensity categories differs across employment and occupational classifications and by race and sex.

Project description:BackgroundAlthough it is generally accepted that physical activity reduces the risk for chronic non-communicable disease and mortality, accumulating evidence suggests that occupational physical activity (OPA) may not confer the same health benefits as leisure time physical activity (LTPA). It is also unclear if workers in high OPA jobs benefit from LTPA the same way as those in sedentary jobs. Our objective was to determine whether LTPA and leisure time sedentary behaviour (LTSB) confer the same health effects across occupations with different levels of OPA.MethodsSearches were run in Medline, Embase, PsycINFO, ProQuest Public Health and Scopus from inception to June 9, 2020. Prospective or experimental studies which examined the effects of LTPA or LTSB on all-cause and cardiovascular mortality and cardiovascular disease, musculoskeletal pain, diabetes, metabolic syndrome, arrhythmias and depression among adult workers grouped by OPA (low OPA/sitters, standers, moderate OPA/intermittent movers, high OPA/heavy labourers) were eligible. Results were synthesized using narrative syntheses and harvest plots, and certainty of evidence assessed with GRADE.ResultsThe review includes 38 papers. Across all outcomes, except cardiovascular mortality, metabolic syndrome and atrial fibrillation, greater LTPA was consistently protective among low OPA, but conferred less protection among moderate and high OPA. For cardiovascular mortality and metabolic syndrome, higher levels of LTPA were generally associated with similar risk reductions among all OPA groups. Few studies examined effects in standers and none examined effects of LTSB across OPA groups.ConclusionsEvidence suggests that LTPA is beneficial for all workers, but with larger risk reductions among those with low compared to high OPA jobs. This suggests that, in our attempts to improve the health of workers through LTPA, tailored interventions for different occupational groups may be required. More high-quality studies are needed to establish recommended levels of LTPA/LTSB for different OPA groups.Protocol registrationPROSPERO # CRD42020191708 .
