In the USA, minority populations face a disproportionate burden from type 2 diabetes (T2D), in whom physical activity (PA) is recommended. The aim of this study was to determine levels of PA among a community of free-living Hispanic/Latino adults with T2D using a research accelerometer, a consumer device and a pictogram self-assessment questionnaire.
This was a cross-sectional, observational study. Participants (57 women and 31 men, body mass index (kg/m) 32.2±7.9 and 29.9±4.5, waist circumference 97.1±30.1 and 93.7±33.0 cm and hemoglobin A1c 8.0±2.0 and 8.1%±1.8%, respectively) wore an ActiGraph (AG) on the hip and a Fitbit (FB) on the wrist for 1 week to estimate daily steps and energy expenditure (EE). Participants reported type and intensity of PA using English-language or Spanish-language pictograms and a 10-point Likert scale (1='not active' to 10='very, very active').
Steps per day were not normally distributed; AG median steps/weekday (Monday-Friday) was 6990 (range 1091-25 884) compared with 9329 (288-31 669) using FB (p≤0.01). Both devices recorded significantly more steps on weekdays versus weekends (p≤0.05). EE was also higher during the week. AG and FB were highly correlated to each other (p<0.01). Men were more active than women and maintained their PA throughout the week, whereas women decreased theirs on weekends. Spanish-language pictograms were preferred and self-reported PA matched objective assessments by both devices. Participants perceived themselves to be active (7.1±2.0) due to work.
Both objectively measured and self-reported levels of PA in Hispanic/Latino adults with T2D challenge the assumption that lack of PA may be commonplace for this group. AG and FB are different in their measurement of PA but are significantly correlated. New strategies, including use of pictograms, for interventions need to be considered if further increases or changes in PA are to be used as T2D therapy.

在美国，少数民族人群患 2 型糖尿病（T2D）的负担不成比例，建议他们进行身体活动（PA）。本研究的目的是使用研究型加速度计、消费类设备和图片自我评估问卷来确定 T2D 社区中自由生活的西班牙裔/拉丁裔成年人的 PA 水平。
这是一项横断面、观察性研究。参与者（57 名女性和 31 名男性，体重指数（kg/m）32.2±7.9 和 29.9±4.5，腰围 97.1±30.1 和 93.7±33.0cm，血红蛋白 A1c 8.0±2.0 和 8.1%±1.8%）在髋部佩戴 ActiGraph（AG），在手腕佩戴 Fitbit（FB），持续 1 周以估计每天的步数和能量消耗（EE）。参与者使用英文或西班牙文图片和 10 分李克特量表（1='不活跃'至 10='非常、非常活跃'）报告 PA 的类型和强度。
每天的步数呈非正态分布；AG 工作日（周一至周五）的中位数步数/周为 6990（范围 1091-25884），而 FB 为 9329（范围 288-31669）（p≤0.01）。两种设备在工作日记录的步数均显著高于周末（p≤0.05）。EE 也在一周内更高。AG 和 FB 彼此高度相关（p<0.01）。男性比女性更活跃，并且在整个星期内保持 PA，而女性在周末则减少 PA。西班牙文图片更受欢迎，并且两种设备的自我报告 PA 与客观评估相匹配。参与者认为自己因工作而活跃（7.1±2.0）。
在患有 T2D 的西班牙裔/拉丁裔成年人中，无论是通过客观测量还是自我报告的 PA 水平，都对缺乏 PA 可能是这一人群的常见现象这一假设提出了挑战。AG 和 FB 在 PA 的测量上有所不同，但相关性显著。如果要将 PA 的增加或改变作为 T2D 的治疗方法，则需要考虑新的策略，包括使用图片。
