RESUMEN
Objective To explore the effect of trans theoretical model in changing on healthy behavior of soldiers on plateau area to prevent hemorrhoids. Methods Fifty-four soldiers respectively from the artillery troops and air defenses force troops were selected and divided into control group that received normal healthy education and treatment group that received the healthy behavior intervene based on transtheoretical model and the changes of the behavior at each stage of intervention were observed and contrasted between two groups. Results There was no statistically significant difference in the number of each stage between two groups at 1 and 3 months after intervention (χ2= 1.514, 6.554, P> 0.05). The number of former intention stage, intention stage, preparation stage, action stage, maintain stage at 6 months after intervention in treatment group were respectively 0, 0, 0, 15, 39 cases, and 2, 3, 6, 20, 23 cases in control group respectively, the difference was statistically significant (χ2=15.843, P0.05). The number of daily training of the levator ani less than 5, 6-15, 16-25, 26-35,>35 times at 3, 6 months after intervention respectively was 5, 6, 6, 17 cases and 20, 0, 0, 0, 14, 40 cases in treatment group respectively, 9, 13, 14, 10, 8 cases, and 3, 4, 6, 22, 19 cases in control group,the differences were statistically significant (χ2=13.459, 22.252, P<0.01). The incidence of bloody at 6 months after intervention was 3.70% (2/54) in treatment group and 16.67% (9/54) in control group, the difference was statistically significant (χ2 = 4.960, P < 0.05). Conclusions The intervene based on transtheoretical model can effectively promote the healthy behavior to prevent hemorrhoids and reduce the recurrence rate of hemorrhoids.
