Hilliness and the Development of Walking Difficulties Among Community-Dwelling Older People
2018
Objective: The objective of this study is to study the associations of objectively defined hilliness with the prevalence and incidence of
walkingdifficulties among community-dwelling older adults, and to explore whether behavioral, health, or socioeconomic factors would fully or partially explain these associations. Method: Baseline interviews (n = 848, 75-90 years) on difficulties in
walking500 m, frequency of moving through the neighborhood, and perceived hilliness as a barrier to outdoor mobility were conducted. Two-year follow-up interviews (n = 551) on difficulties in
walking500 m were conducted among participants without baseline
walkingdifficulties. Hilliness objectively defined as the mean slope in 500-m road network. Results: Logistic regression showed that hilliness was associated with incident
walkingdifficulties at the 2-year follow-up (odds ratio [OR] = 1.66, 95% confidence interval [CI] = [1.09, 2.51]) but not with the prevalence of
walkingdifficulties at baseline. Adding behavioral, h...
