Lifestyle modifications are associated with better outcomes for patients with diabetes. Patients' awareness of having diabetes may promote lifestyle changes, but there is limited evidence to support this assertion. This study examined whether a report of physician-diagnosed diabetes is associated with dietary changes and efforts to lose weight.
Cross-sectional comparison of individuals with and without diabetes or prediabetes diagnosis, matched on glycosylated hemoglobin (HbA1c) level, socio-demographic characteristics, and health status using propensity-score matching analysis. Non-pregnant US adult participants (aged 20 and older with an HbA1c level between 5.7% and 7.5%) in the 1999-2014 National Health and Nutrition Examination Survey were included (N = 10,781).
Compared with matched controls who did not report having diabetes or prediabetes (N = 1,769), persons with a diagnosis of diabetes or prediabetes (N = 1,769) reported less sugar consumption (14.9 grams [95% CI: 8.9 to 21.0]); less carbohydrate consumption (11.6 grams [95% CI: 1.7 to 21.5]); higher rates of trying to lose weight (12.3 percentage points [95% CI: 5.3 to 19.2]); and a greater one-year weight reduction (4.8 ounces [95% CI: 3.3 to 6.4]).
Awareness of a diagnosis of diabetes or prediabetes from a health profession is associated with the uptake of recommended life-style modifications.
生活方式的改变与糖尿病患者更好的治疗结果相关。患者对患糖尿病的认知可能会促进生活方式的改变，但支持这一论断的证据有限。本研究调查了医生诊断为糖尿病的报告是否与饮食变化和减肥努力有关。
使用倾向得分匹配分析，对有和没有糖尿病或糖尿病前期诊断的个体进行横断面比较，匹配糖化血红蛋白（HbA1c）水平、社会人口学特征和健康状况。纳入1999 - 2014年美国国家健康和营养检查调查中的非妊娠成年参与者（年龄在20岁及以上，HbA1c水平在5.7%至7.5%之间）（N = 10,781）。
与未报告患有糖尿病或糖尿病前期的匹配对照组（N = 1,769）相比，诊断为糖尿病或糖尿病前期的个体（N = 1,769）报告糖摄入量较少（14.9克[95%可信区间：8.9至21.0]）；碳水化合物摄入量较少（11.6克[95%可信区间：1.7至21.5]）；尝试减肥的比例较高（12.3个百分点[95%可信区间：5.3至19.2]）；以及一年体重减轻更多（4.8盎司[95%可信区间：3.3至6.4]）。
从医疗专业人员处得知糖尿病或糖尿病前期的诊断与采取推荐的生活方式改变有关。
