目的对男性献血者共用剃刀干预强度和干预效果的关系进行探索,从而为建立规范的使用共用剃刀的干预模式提供依据。方法把313名男性献血者随机分成对照组、单次干预组与3次干预组,通过个体干预及定期回访并对效果进行评价。结果干预后1个月对照组、单次干预组和3次干预组人员在理发店内使用共用剃刀的比例分别为56.1%、17.1%和16.4%。6个月回访时,3组人员在理发店内使用共用剃刀的比例分别为61.2%、55.2%和18.2%。1年回访时,3组人员在理发店内使用共用剃刀的比例为62.2%、58.1%和27.3%;单次干预组与对照组的OR值为0.647(95%CI=0.400,0.952;P=0.029);3次干预组与对照组的OR值是0.311(95%CI=0.200、0.485,P<0.01)。结论该干预模式能有效的促使献血者改变使用共用剃刀的习惯,干预强度与干预效果有明显关系。
Objective To explore the relationship between male razor intervention intensity and intervention effect in male blood donors, so as to provide a basis for establishing a normative intervention mode using common razor. Methods A total of 313 male donors were randomly divided into control group, single intervention group and three intervention groups. Individual intervention and regular follow-up were performed to evaluate the effect. Results One month after intervention, the proportions of the common razors in the barber shop were 56.1%, 17.1% and 16.4% respectively in the control group, the single intervention group and the three intervention groups. At the 6-month visit, the proportions of the three groups of people who used the shared razor in the hairdresser were 61.2%, 55.2% and 18.2%, respectively. In the 1-year visit, the rate of using common razors in the barbershop was 62.2%, 58.1% and 27.3% respectively in the three groups. The OR of the single intervention group and the control group was 0.647 (95% CI = 0.400, 0.952; P = 0.029 ). The OR of the 3 interventions and the control group was 0.311 (95% CI = 0.200, 0.445, P <0.01). Conclusion The intervention model can effectively promote blood donors to change the habit of using a common razor, intervention intensity and the effect of intervention has a clear relationship.
