目标.本研究探讨了老年人的社会人口学和健康特征和问题。对1249名来自康涅狄格州纽黑文市老年人流行病学研究既定人群社区的72岁或以上的登记者进行了访谈和评估，他们同意参加第七次随访。大约11%的纽黑文居民报告过马路有困难。在一项或多项日常生活活动中需要帮助的老年行人是其他人的10倍以上，而那些步行速度最慢的人报告过马路困难的可能性是其他人的近3倍。在这些72岁或以上的行人中，只有不到1%的人在信号交叉口通常分配的时间内（1.22米/秒）有足够的正常步行速度过马路。在有大量老年人的地区，应延长信号交叉口的过街时间，并应修改信号交叉口计时的建议步行速度，以反映老年行人的能力范围。
Objectives. This study examined the sociodemographic and health characteristics and problems of older pedestrians.Methods. Interviews and assessments were conducted with 1249 enrollees aged 72 or older from the New Haven, Conn, community of the Established Populations for Epidemiologic Studies of the Elderly who agreed to participate in a seventh follow-up.Results. Approximately 11% of the New Haven residents reported difficulty crossing the street. Older pedestrians needing help in one or more activities of dairy living were more than 10 times as likely as others, and those with the slowest walking speeds were nearly 3 times as likely as others, to report difficulty crossing the street. Fewer than 1% of these pedestrians aged 72 or older had a normal walking speed sufficient to cross the street in the time typically allotted at signalized intersections (1.22 m/sec).Conclusions. Crossing times at signalized intersections in areas with large populations of elders should be extended, and the recommended walking speed for timing signalized crossings should be modified to reflect the range of abilities among older pedestrians.
