Frequency of Health Service Received by Subjects
The 2 groups were drawn from a single district and were similar at baseline in terms of annual average income, access to health services, and main demographic characteristics (Table 1). Figure 1 shows the progress of subjects through the study. According to the requirements of our study, all subjects with COPD participated in the activities provided by the caregivers. In total, the subjects received a mean _ SD of 96 _ 12.6 follow-ups by caregivers. The greatest number of follow-ups was 112, which accounted for 85.2% (3,576/4,197) of the study population, whereas 71 was the least number of follow-ups, accounting for 4.5% (189/4,197) of all subjects. In our study, 86.7% of subjects attended the 48 COPD health education lectures. The participation rates for mandated daily breathing exercise training, abdominal respiration, breathing exercises, and limb training were 95.6%, 94.3%, 94.1%, and 91.5%, respectively. Although 100% of subjects reported that they paid attention to their everyday diet, only 47% of subjects insisted on eating 3 meals/d as dictated by the requirements of the dietary guidelines.
