Association between subjective walking speed and metabolic diseases in individuals with obesity: a cross-sectional analysis

Le résumé fourni par la source

The association between subjective walking speed and metabolic diseases has received limited attention, particularly in individuals with obesity. We aimed to clarify this association using comprehensive health checkup data of participants with obesity. In total, 8578 individuals with a body mass index ≥ 25.0 kg/m 2 , 9626 individuals with waist circumference ≥ 85 cm in men and ≥ 90 cm in women, and 6742 individuals who met both criteria of body mass index and waist circumference were included in this cross-sectional analysis. Subjective walking speed was investigated using the question “Is your walking speed faster than the speed of those of your age and sex?” in a health examination questionnaire. Metabolic diseases were defined according to the guidelines for each disease, and modified Poisson regression analyses were performed. In the model adjusted for age and sex, individuals with obesity based on body mass index and fast subjective walking speed showed significantly lower risk of diabetes mellitus (risk ratio [RR] 0.70; 95% CI 0.63–0.77) and dyslipidemia (RR 0.97; 95% CI 0.94–1.00). Similarly, among those with obesity based on waist circumference and both body mass index and waist circumference, fast subjective walking speed showed a significant negative association with hypertension (RR 0.94; 95% CI 0.90–0.97 and RR 0.95; 95% CI 0.92–0.99, respectively), diabetes mellitus (RR 0.70; 95% CI 0.64–0.77 and RR 0.70; 95% CI 0.63–0.77, respectively), and dyslipidemia (RR 0.96; 95% CI 0.94–0.99 and RR 0.96; 95% CI 0.94–0.99, respectively). Thus, among individuals with obesity, the odds of metabolic diseases were lower if their subjective walking speed was fast. This study contributes to earlier prevention of the cascade of diseases that begin with obesity.
