ORIGINAL RESEARCH

Effectiveness of a Community-Based Individualized Lifestyle Intervention Among Older Adults With Diabetes and Hypertension, Tianjin, China, 2008–2009

During phase I of the study, the early group received a 3-month lifestyle intervention program on improving physical activity and dietary patterns while the late group received usual standard health care, serving as controls during their 3-month waiting period. During phase II of the study, the early group received a 3-month follow-up without more intervention while the late group received the 3-month intervention. Recruitment and baseline data collection for both groups occurred at the start of phase I. In both the early and late groups, during their intervention period participants had weekly consultation sessions during the first month and then every other week for the following 2 months. In the early group, postintervention data were collected at the end of the 3-month intervention; at the same time, preintervention data were collected for the late group. At the end of phase II, follow-up data were collected for the early group and postintervention data were collected for the late group.
