Reach
Of 68 PHCs, we gained the cooperation of 30 PHCs. Fifteen out of the contacted PHCs in the intervention group, we invited 300 eligible patients to attend the program. About 235 (78.3%) of those were willing to participate (Fig.1). The main reasons for refusal were not having enough time (n=36), tied up with work (n=11), inconvenient to travel (n=10), and taking care of child/older person in their family (n=8); however, these reasons are common in daily life. No significant differences in characteristics (gender, age, education, and marital status) were found between participants and people who refused to participate.
