We propose general health promotion action (GHPA) to represent the general intention and actual practices aimed to promote health. The transtheoretical model (TTM) has not been applied to GHPA. The objectives of this study were to determine whether TTM can be applied to Chinese adults by measuring the subjects' stage of change for GHPA, and to study whether stage for GHPA is associated with health-related lifestyle practices.
Randomly selected Hong Kong Chinese subjects (3233) aged 18-64 were interviewed in telephone survey.
Thirty-nine percent had not taken any health promotion actions and had no intention to do so (precontemplation). Twelve percent had taken action but had no intention to continue (at-risk for relapse). Three percent had not taken any actions and intended to do so in the next 6 months, but not in the next 1 month (contemplation). Eleven percent had not taken any actions but intended to do so in the next 1 month (preparation). Fifteen percent had been taking action for less than 6 months and intended to continue (action). Twenty-one percent had been taking action for at least 6 months and intended to continue (maintenance). Precontemplators were less likely than maintainers to be never smokers (OR = 0.62; 95% CI = 0.49-0.80), exercisers (0.097; 0.077-0.12), to eat fruit twice a day (0.53; 0.41-0.69) and remove fat when eating (0.72; 0.54-0.95), with increasing trends in the odds of reporting these practices from precontemplation to maintenance.
Our findings have provided preliminary findings on the applicability of TTM on GHPA in Chinese adults with evidences of concurrent criterion validity.
我们提出一般健康促进行动（GHPA）来代表旨在促进健康的总体意图和实际做法。跨理论模型（TTM）尚未应用于GHPA。本研究的目的是通过测量受试者在GHPA方面的改变阶段来确定TTM是否可应用于中国成年人，并研究GHPA阶段是否与健康相关的生活方式行为相关。
在电话调查中对随机选取的3233名年龄在18 - 64岁的中国香港受试者进行访谈。
39%的人未采取任何健康促进行动且无意这样做（前意向阶段）。12%的人已采取行动但无意继续（复发风险阶段）。3%的人未采取任何行动，但打算在未来6个月内这样做，但不是在接下来的1个月内（沉思阶段）。11%的人未采取任何行动，但打算在接下来的1个月内这样做（准备阶段）。15%的人采取行动不到6个月且打算继续（行动阶段）。21%的人采取行动至少6个月且打算继续（维持阶段）。前意向者比维持者更不可能从不吸烟（比值比[OR]=0.62；95%置信区间[CI]=0.49 - 0.80）、进行锻炼（0.097；0.077 - 0.12）、每天吃两次水果（0.53；0.41 - 0.69）以及在进食时去除脂肪（0.72；0.54 - 0.95），从前意向阶段到维持阶段，报告这些行为的几率呈上升趋势。
我们的研究结果为TTM在中国成年人GHPA中的适用性提供了初步发现，并具有同时效度的证据。
