Gait speed and sagittal abdominal diameter: The results from the Handan Eye Study

Abstract

Abstract The objective was to examine the relationship between GS and BMI, WC, waist-hip ratio (WHR), SAD-heigh ratio (SADHtR), WC-height ratio (WCHtR), SAD-WC ratio (SWR). This was a cross-sectional analysis. 2852 participants were included. Unadjusted analyses were performed to estimate the gender-specific means of GS according to each anthropometric index category. Furthermore, the mean of GS according to SWR interquartile was adjusted by age. Multivariate linear regression for GS was performed by SPSS. After adjustment for age, the negative correlation between SWR and GS was confirmed in overall population (t=-2.977, P = 0.003) and in women (t=-2.509, P = 0.012), not in men. The age-adjusted means of GS were 0.983 (95% CI 0.978–0.989) m/sec in SWR 1st IQR, 0.980 (95% CI 0.974–0.987) m/sec in 2nd IQR, and 0.980 (95% CI 0.973–0.986) m/sec in 3th IQR and 0.969 (95% CI 0.963–0.976) m/sec in 4th IQR. Adjust by serum albumin, hypertension and diabetes, the relationship between GS and SWR was still negative correlation in general population(t=-2.257, P = 0.024). This confirms Higher SWR is associated with lower GS. Age and gender should be considered when we explore the relationship between GS and SWR in older adults.
