Many studies have demonstrated the effectiveness of primary prevention strategies in type 2 diabetes, however, questions remain around the feasibility of high resource, intensive interventions within a healthcare setting. We report the results of a dietitian-led pre-diabetes education session targeting healthy eating and active living as strategies for weight reduction.
Participants were asked to complete a baseline questionnaire prior to completing the pre-diabetes education session and were sent follow-up questionnaires at 3 and 6 months. Differences between participants at baseline, 3 and 6 months were determined using χ(2), t-tests and ANOVA.
Of the 211 participants asked to fill out baseline questionnaires, 45 participants completed questionnaires at baseline, 3 months and 6 months. Although we observed general trends towards improvements in diet, physical activity and weight related behaviours among the 45 completers, no significant changes were observed among participants between questionnaire periods.
A "one-off", theory-guided group education session may be insufficient to support lifestyle modifications in the context of weight management in a pre-diabetic population. Further evaluation of the efficacy and feasibility of the PCN as a setting for lifestyle intervention is required.
许多研究已证明2型糖尿病一级预防策略的有效性，然而，在医疗环境中实施高资源、高强度干预措施的可行性仍存在疑问。我们报告了由营养师主导的糖尿病前期教育课程的结果，该课程将健康饮食和积极生活作为减重策略。
参与者在完成糖尿病前期教育课程之前被要求填写一份基线问卷，并在3个月和6个月时收到随访问卷。使用χ(2)检验、t检验和方差分析确定参与者在基线、3个月和6个月时的差异。
在211名被要求填写基线问卷的参与者中，有45名参与者在基线、3个月和6个月时完成了问卷。尽管我们在45名完成者中观察到饮食、身体活动和体重相关行为总体上有改善的趋势，但在问卷期间参与者之间未观察到显著变化。
在糖尿病前期人群的体重管理背景下，一次理论指导的小组教育课程可能不足以支持生活方式的改变。需要进一步评估初级保健网络作为生活方式干预场所的有效性和可行性。
