Patients have a major role in the control and treatment of type 2 diabetes. So, knowledge of different aspects of this disease especially diet therapy is very important for these patients. This study was conducted to determine the effectiveness of the Health Belief Model (HBM) on nutrition education in type 2 diabetic patients.
Eighty eight type 2 diabetic patients attending Iranian Diabetes Association seminars were randomly selected to participate in the study (44 in intervention group and 44 in control group). The intervention was consisted of two educational sessions each one for 80 minutes. Data were collected by a validated and reliable questionnaire (58 questions) before intervention and one month after intervention.
AFTER INTERVENTION, KNOWLEDGE SCORES INCREASED IN THE INTERVENTION GROUP COMPARED TO THE CONTROL GROUP (MEAN DIFFERENCES IN THE INTERVENTION AND TEST GROUP: 22.68 ± 15.90 vs - 2.27 ± 17.30, P < 0.001). Perceived susceptibility increased significantly in the intervention group compared to the control group (27.5 ± 18.5 vs 3.9 ± 17.2, P < 0.001). The result was the same for perceived severity, perceived threatened and perceived benefits (P < 0.001). In contrast perceived barriers reduced in the intervention group compared to the control diet (-14.7 ± 13.3 vs 0.9 ± 13.9, P < 0.001). In the intervention group, behavior grades increased more than control group (34.61 ± 14.93 vs -0.23 ± 8.52, P < 0.001).
The efficacy of the health belief model in nutritional education to the diabetic patients was confirmed in the present study.
患者在2型糖尿病的控制和治疗中起着重要作用。因此,了解这种疾病的不同方面,尤其是饮食疗法,对这些患者非常重要。本研究旨在确定健康信念模式(HBM)对2型糖尿病患者营养教育的有效性。
随机选择88名参加伊朗糖尿病协会研讨会的2型糖尿病患者参与研究(干预组44名,对照组44名)。干预包括两次每次80分钟的教育课程。在干预前和干预后一个月,通过一份经过验证且可靠的问卷(58个问题)收集数据。
干预后,干预组的知识得分相比对照组有所增加(干预组与测试组的平均差异:22.68±15.90对 -2.27±17.30,P<0.001)。与对照组相比,干预组的感知易感性显著增加(27.5±18.5对3.9±17.2,P<0.001)。感知严重性、感知威胁和感知益处的结果相同(P<0.001)。相比之下,干预组的感知障碍相比对照饮食有所减少(-14.7±13.3对0.9±13.9,P<0.001)。在干预组中,行为等级的增加超过对照组(34.61±14.93对 -0.23±8.52,P<0.001)。
本研究证实了健康信念模式在糖尿病患者营养教育中的有效性。
