The objective of this study was to determine the association between pedometer-assessed steps and type 2 diabetes risk using the Public Health Agency of Canada-developed 16-item Canadian Diabetes Risk Questionnaire (CANRISK) among a large population-based sample of older adults across Alberta, Canada. To achieve our study objective, adults without type 2 diabetes (N = 689) aged 55 years and older provided demographic data and CANRISK scores through computer-assisted telephone interviews between September and November 2012. Respondents also wore a step pedometer over 3 consecutive days to estimate average daily steps. Logistic regression was used to assess the association between achieving 7500 steps/day and risk of diabetes (low vs. moderate and high). Overall, 41% were male, average age was 63.4 (SD 5.5) years, body mass index was 26.7 (SD 5.0) kg/m, and participants averaged 5671 (SD 3529) steps/day. All respondents indicated they were capable of walking for at least 10 min unassisted. CANRISK scores ranged from 13-60, with 18% in the low-risk category (<21). After adjustment, those not achieving 7500 steps/day (n = 507) were more than twice as likely to belong to the higher risk categories for type 2 diabetes compared with those walking ≥7500 steps/day (n = 182) (73.6% vs. 26.4%; odds ratio: 2.37; 95% confidence interval: 1.58 - 3.57). Among older adults without diabetes, daily steps were strongly and inversely associated with diabetes risk using the CANRISK score. Walking remains an important modifiable risk factor target for type 2 diabetes and achieving at least 7500 steps/day may be a reasonable target for older adults.
本研究的目的是,在加拿大艾伯塔省大量以人群为基础的老年人样本中,使用加拿大公共卫生署编制的16项加拿大糖尿病风险问卷(CANRISK),确定计步器评估的步数与2型糖尿病风险之间的关联。为实现我们的研究目标,年龄在55岁及以上且无2型糖尿病的成年人(N = 689),于2012年9月至11月期间通过计算机辅助电话访谈提供了人口统计学数据和CANRISK评分。受访者还连续3天佩戴步数计,以估计平均每日步数。采用逻辑回归分析,评估每日步数达到7500步与糖尿病风险(低风险与中高风险)之间的关联。总体而言,41%为男性,平均年龄为63.4(标准差5.5)岁,体重指数为26.7(标准差5.0)kg/m²,参与者平均每日步数为5671(标准差3529)步。所有受访者均表示,他们能够在无人协助的情况下行走至少10分钟。CANRISK评分范围为13 - 60,其中18%属于低风险类别(<21)。调整后,与每日步数≥7500步的受访者(n = 182)相比,未达到每日7500步的受访者(n = 507)患2型糖尿病的高风险类别的可能性高出两倍多(73.6%对26.4%;优势比:2.37;95%置信区间:1.58 - 3.57)。在无糖尿病的老年人中,使用CANRISK评分,每日步数与糖尿病风险呈强烈负相关。步行仍然是2型糖尿病重要的可改变风险因素目标,对于老年人而言,每日至少达到7500步可能是一个合理目标。
