The implementation project of the national diabetes prevention programme in Finland, FIN-D2D, was carried out in primary health care in the area of five hospital districts during 2003-2007.
The population strategy of FIN-D2D was primarily aimed at increasing the awareness of type 2 diabetes and preventing obesity. To investigate the effects of this strategy, we studied the changes in the prevalence of obesity, overweight, and central obesity among a random independent sample of individuals aged 45-74 years in the FIN-D2D area; and assessed whether they differed from a sample of individuals in the control area, which consisted of four geographical areas not participating in FIN-D2D (FINRISK study). Data was obtained for 5850/ 6406 (in the beginning/ in the end) individuals. The duration of the observation period varied from three to five years.
The mean body weight decreased from 78.7 to 78.1 kg (p = 0.041) in the FIN-D2D area, and from 78.7 to 78.0 kg (p = NS) in the control area. The prevalence of obesity (BMI ≥30 kg/m(2)) decreased in the FIN-D2D area (26.5% vs. 24.4%, p = 0.015), and in the control area (28.4% vs. 25.2%, p = 0.005). The prevalence of morbid obesity (BMI ≥40 kg/m(2)) remained unchanged in the FIN-D2D area, but increased in the control area (1.2% vs. 2.3%, p = 0.007). The mean waist circumference remained unchanged in the FIN-D2D area, but increased in the control area (92.8 vs. 94.0 cm, p = 0.005).
The prevalence of obesity may be decreasing among 45-74 year old Finns. We still need a longer time perspective and future studies to see whether this favourable trend can be sustained in Finland. The actions of this implementation project can at least partly explain the differences in the mean waist circumference and the prevalence of morbid obesity between the intervention and control areas.
芬兰的国家糖尿病预防计划实施项目（FIN-D2D）于 2003-2007 年在五个医院区的基层医疗保健中开展。
FIN-D2D 的人群策略主要旨在提高对 2 型糖尿病的认识和预防肥胖。为了研究这一策略的效果，我们研究了 FIN-D2D 地区 45-74 岁随机独立样本个体中肥胖、超重和中心性肥胖的患病率变化；并评估了他们是否与不参与 FIN-D2D 的四个地理区域（FINRISK 研究）的样本不同。共获得了 5850/6406（开始时/结束时）名个体的数据。观察期的持续时间从三年到五年不等。
FIN-D2D 地区的平均体重从 78.7 公斤降至 78.1 公斤（p=0.041），对照组从 78.7 公斤降至 78.0 公斤（p=NS）。FIN-D2D 地区肥胖（BMI≥30kg/m²）的患病率下降（26.5%比 24.4%，p=0.015），对照组（28.4%比 25.2%，p=0.005）。FIN-D2D 地区病态肥胖（BMI≥40kg/m²）的患病率保持不变，但对照组增加（1.2%比 2.3%，p=0.007）。FIN-D2D 地区的平均腰围保持不变，但对照组增加（92.8 比 94.0 厘米，p=0.005）。
45-74 岁芬兰人的肥胖患病率可能正在下降。我们仍需要更长的时间来看芬兰能否保持这种有利趋势。该实施项目的行动至少可以部分解释干预和对照组之间平均腰围和病态肥胖患病率的差异。
