Diabetes is a growing worldwide problem. Ascertaining its prevalence is vital as a starting point to establish and measure the success of health interventions. This study aimed to determine the prevalence of Type 2 diabetes and 'pre-diabetes', defined as impaired fasting glucose and impaired glucose tolerance, in the Portuguese population aged between 20 and 79 years.
Considering the number of inhabitants between 20 and 79 years old, statistical units were selected that were representative regionally and nationally. The total sample comprised 5167 subjects. National prevalence was calculated. Analyses were performed on all those without previously known diabetes using World Health Organization reference diagnostic criteria.
We found a diabetes prevalence of 11.7% (95% confidence interval 10.8-12.6%), with a significant difference between men (14.2%; 95% confidence interval 12.5-15.5%) and women (9.5%; 95% confidence interval 8.5-10.6%). While 6.6% of the subjects had previously been diagnosed with diabetes, 5.1% were undiagnosed. By age groups, 2.4% of the population between 20 and 39 years, 12.6% of people from 40 to 59 years old and 26.3% of those aged between 60 and 79 years had diabetes. Prevalence of 'pre-diabetes' (impaired fasting glucose, impaired glucose tolerance or both) in the population was 23.3%.
Diabetes has a high prevalence in Portugal. If 'pre-diabetes' is also considered, about one-third (34.9%) of the population aged 20-79 years is affected. A greater number of males were found to have diabetes. We detected a high percentage of people with undiagnosed diabetes (43.6%).
糖尿病是一个全球性的日益严重的问题。确定其流行率至关重要，因为这是确定和衡量健康干预措施成功的起点。本研究旨在确定葡萄牙 20-79 岁人群中 2 型糖尿病和“糖尿病前期”（定义为空腹血糖受损和葡萄糖耐量受损）的流行率。
考虑到 20-79 岁之间的居民人数，选择了具有区域和全国代表性的统计单位。总样本包括 5167 名受试者。计算了全国流行率。对所有未确诊糖尿病的人进行了分析，使用世界卫生组织参考诊断标准。
我们发现糖尿病的患病率为 11.7%（95%置信区间为 10.8-12.6%），男性（14.2%；95%置信区间为 12.5-15.5%）和女性（9.5%；95%置信区间为 8.5-10.6%）之间存在显著差异。虽然 6.6%的受试者以前被诊断患有糖尿病，但 5.1%的人未被诊断。按年龄组划分，20-39 岁人群中有 2.4%，40-59 岁人群中有 12.6%，60-79 岁人群中有 26.3%患有糖尿病。该人群中“糖尿病前期”（空腹血糖受损、葡萄糖耐量受损或两者兼有）的患病率为 23.3%。
糖尿病在葡萄牙的患病率很高。如果也考虑“糖尿病前期”，则约三分之一（34.9%）的 20-79 岁人群受到影响。发现更多的男性患有糖尿病。我们检测到未确诊糖尿病的人数比例较高（43.6%）。
