| Résumé : | [BDSP. Notice produite par INIST-CNRS R0xD9CIt. Diffusion soumise à autorisation]. Background Socio-economic influences over a lifetime impact on health and may contribute to poor physical functioning in old age. Methods The authors examined the impact of both childhood and adulthood socio-economic factors on locomotor function at 63-86 years (measured with the get up and go timed walk and flamingo balance test) in the UK-based Boyd Orr (n=405) and Caerphilly (n=1196) prospective cohorts. Results There was a marked reduction in walking speed and balance time with increasing age. Each year of age was associated with a 1.7% slower walk time and a 14% increased odds of poor balance. Participants who moved from a low socio-economic position in childhood to a high socio-economic position in adulthood had 3% slower walking times (95% CI - 2% to 8%) than people with a high socio-economic position in both periods. Participants who moved from a high socio-economic position in childhood to a low adulthood socio-economic position had 5% slower walking times (95% CI - 2% to 12%). Participants with a low socio-economic position in both periods had 10% slower walking times (95% CI 5% to 16% ; p for trend<0.001). In Boyd Orr, low socio-economic position in childhood was associated with poor balance in old age (OR per worsening category=1 1.26 ; 95% Cl 1.01 to 1.57 ; p=0.043), as was socio-economic position in adulthood (OR=1.71 ; 95% CI 1.20 to 2.45 ; p=0.003). Similar associations were not observed in Caerphilly. Conclusion Accumulating socio-economic disadvantage from childhood to adulthood is associated with slower walking time in old age, with mixed results for balance ability. |
