Association between weekend warrior physical activity pattern and bone mineral density among adults: national health and nutrition examination survey
Authors' conclusion
Among US adults, the WW PA pattern was significantly associated with increased femoral neck BMD, with benefits comparable to those observed in the RA pattern.
Study context
- Population
- NHANES adults aged ≥18 years; mean age 53.6 ± 17.2 years, 8677 men (51.2%) and 8260 women (48.8%); Physical activity (PA) patterns self-reported by questionnaire
- Participants
- 16,937 adults
- Exposure
- PA patterns vs inactive
- Inactiven = 9,123reference
- Insufficiently activen = 2,559
- Weekend warrior (WW)n = 952
- Regularly active (RA)n = 4,303
- Outcome
- Femoral neck BMD
Methodological detailsNHANES, multivariable linear regression, subgroup and sensitivity analyses

Main finding
As reported in the abstract
Femoral neck BMD (adjusted)
β
0.027
95% CI 0.020–0.033P < 0.001
WW
β
0.034
95% CI 0.025–0.044P < 0.001
RA
Observational data: associations, not effects.
Further findings
Femoral neck bone mineral density (BMD) by subgroup
- Younger adults (<50 years), males and unmarried individuals may derive greater BMD benefits from WW and RA patterns
