Objective

To examine the association of weight status with level of diabetes knowledge (symptoms and complications) among residents of Jeddah City, Saudi Arabia.

Methods

In a cross-sectional study, a questionnaire assessing sociodemographic and health characteristics and knowledge about diabetes and its symptoms and complications was utilized. Data of 3978 adults, 18 years of age or older, were collected from public mall sites in Jeddah city and surrounding areas. Participants were divided into three tertiles based on their knowledge scores. Weight and height were measured following standardized procedures, and body weight categories were defined based on body mass index (BMI). The association between weight status and tertiles of diabetes knowledge was examined using multinomial logistic regression analysis.

Results

Compared to normal-weight participants, participants who were underweight, overweight, or obese, did not differ with regards to knowledge about diabetes symptoms. Adjusted models showed that overweight and obese participants had lower odds of being in the lowest tertile of knowledge about diabetes complications compared to normal-weight participants (OR: 0.71, 95% CI: 0.58–0.86 and OR: 0.64, 95% CI: 0.51–0.79, respectively). With regards to general knowledge about diabetes, the knowledge of participants who were underweight did not differ when compared to normal-weight participants. Overweight and obese participants had lower odds of being in the lowest tertile of general knowledge about diabetes compared to normal-weight participants (OR: 0.78, 95% CI: 0.62–0.97 and OR: 0.60, 95% CI: 0.47–0.76, respectively).

Conclusions

Overweight and obese individuals have better knowledge about diabetes compared to normal-weight individuals. Public health programs need to take into account the level of diabetes knowledge and tailor interventions to aid behavior and lifestyle change.

沙特阿拉伯吉达市居民的糖尿病知识及其与体重状况的关系

客观的

研究沙特阿拉伯吉达市居民体重状况与糖尿病知识水平（症状和并发症）的关系。

方法

在一项横断面研究中，使用了一份问卷，该问卷评估了社会人口统计学和健康特征以及有关糖尿病及其症状和并发症的知识。从吉达市及周边地区的公共购物中心收集了3978名18岁以上成年人的数据。参与者根据他们的知识得分分为三个三分位数。体重和身高是按照标准化程序进行测量的，体重类别是根据体重指数（BMI）定义的。体重状况与糖尿病知识的三分位数之间的关联使用多项逻辑回归分析进行了检验。

结果

与体重正常的参与者相比，体重不足，超重或肥胖的参与者在糖尿病症状方面的知识没有差异。校正后的模型显示，与正常体重的参与者相比，超重和肥胖的参与者对糖尿病并发症的了解最低的几率较低（OR：0.71，95％CI：0.58–0.86； OR：0.64，95％CI：0.51 –0.79）。关于糖尿病的一般知识，与正常体重的参与者相比，体重不足的参与者的知识没有差异。与正常体重的参与者相比，超重和肥胖的参与者在糖尿病常识中处于最低三分位数的几率更低（OR：0.78、95％CI：0.62-0.97和OR：0.60，95％CI：0.47-0.76 ）。

结论

与正常体重的人相比，超重和肥胖的人对糖尿病有更好的了解。公共卫生计划需要考虑到糖尿病知识水平，并量身定制干预措施，以帮助行为和生活方式的改变。
