The correlates of this high-impact physical activity (PA) in later life are unknown. / Methods: Participants were from the Cohort for Skeletal Health in Bristol and Avon, Hertfordshire Cohort Study and MRC National Survey of Health and Development. Associations of demographic, behavioural, physiological and psychological factors with vertical acceleration peaks ≥1.5 g (i.e. high-impact PA) from 7-day hip-worn accelerometer recordings were examined using linear regression. / Results: A total of 1187 participants (mean age = 72.7 years, 66.6% females) were included. Age, sex, education, active transport, self-reported higher impact PA, walking speed and self-rated health were independently associated with high-impact PA whereas BMI and sleep quality showed borderline independent associations. For example, differences in log-high-impact counts were 0.50 (P < 0.001) for men versus women and −0.56 (P < 0.001) for worst versus best self-rated health. Our final model explained 23% of between-participant variance in high impacts. Other correlates were not associated with high-impact activity after adjustment. / Conclusions: Besides age and sex, several factors were associated with higher impact PA in later life. Our findings help identify characteristics of older people that might benefit from interventions designed to promote osteogenic PA. date: 2018-12 date_type: published official_url: https://doi.org/10.1093/pubmed/fdx171 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1511228 doi: 10.1093/pubmed/fdx171 lyricists_name: Cooper, Rachel lyricists_name: Gaysin, Timur lyricists_name: Kuh, Diana lyricists_name: Wong, Andrew lyricists_id: RCOOP16 lyricists_id: TGAYS51 lyricists_id: DKUHX97 lyricists_id: AWKWO84 actors_name: Cooper, Rachel actors_name: Pilling, Stephanie actors_id: RCOOP16 actors_id: SARMS84 actors_role: owner actors_role: impersonator full_text_status: public publication: Journal of Public Health volume: 40 number: 4 pagerange: 727-737 citation: Elhakeem, A; Hannam, K; Deere, KC; Hartley, A; Clark, EM; Moss, C; Edwards, MH; ...
