Abstract:
The prevention of type 2 diabetes (T2D) in high-risk people with lifestyle interventions has been demonstrated by several randomized controlled trials. The intervention effect has sustained up to 20 years in post-trial monitoring of T2D incidence. In 2000, Finland launched the national T2D prevention plan. For screening for high T2D risk, the non-laboratory Finnish Diabetes Risk Score was developed and widely used, also in other countries. The incidence of drug-treated T2D has decreased steadily since 2010. The US congress authorized public funding for a national diabetes prevention program (NDPP) in 2010. It was built around a 16-visit program that relies on referral from primary care and self-referral of persons with either prediabetes or by a diabetes risk test. The program uses a train-the-trainer program. In 2015 the program started the inclusion of online programs. There has been limited implementation of nationwide T2D prevention programs in other countries. Despite the convincing results from RCTs in China and India, no translation to the national level was introduced there. T2D prevention efforts in low-and middle-income countries are still limited, but results have been promising. Barriers to efficient interventions are greater in these countries than in high-income countries, where many barriers also exist. Health disparities by socioeconomic status exist for T2D and its risk factors and form a challenge for preventive interventions. It seems that a stronger commitment to T2D prevention is needed, such as the successful WHO Framework Convention on Tobacco Control, which legally binds the countries to act.
Insights
Lifestyle interventions effectively prevent type 2 diabetes (T2D) in high-risk individuals, with sustained effects for up to 20 years. National programs in Finland and the US show promise, but wider implementation is needed globally.
Area of Science:
- Public Health
- Preventive Medicine
- Epidemiology
Background:
- Randomized controlled trials demonstrate the efficacy of lifestyle interventions in preventing type 2 diabetes (T2D) among high-risk populations.
- Long-term monitoring shows sustained intervention effects on T2D incidence for up to 20 years.
- National T2D prevention strategies, like Finland's (2000) and the US National Diabetes Prevention Program (NDPP, 2010), have been established.
Purpose of the Study:
- To review the evidence for lifestyle interventions in T2D prevention.
- To examine the implementation and outcomes of national T2D prevention programs.
- To identify barriers and facilitators for T2D prevention, particularly in low- and middle-income countries.
Main Methods:
- Review of randomized controlled trials (RCTs) on lifestyle interventions for T2D prevention.
- Analysis of national T2D prevention program data and policy initiatives.
- Examination of T2D incidence trends and risk factor disparities.
Main Results:
- National programs in Finland and the US have shown success, with decreasing T2D incidence observed.
- The Finnish Diabetes Risk Score is a widely adopted screening tool.
- Online program components have been integrated into the US NDPP.
- Limited nationwide implementation exists in other countries, despite promising RCT results from China and India.
- Barriers to intervention are significant in low- and middle-income countries and also present in high-income nations.
- Socioeconomic disparities pose a challenge to T2D prevention efforts.
Conclusions:
- Stronger global commitment to T2D prevention is essential, potentially modeled after successful public health treaties like the WHO Framework Convention on Tobacco Control.
- Addressing socioeconomic disparities is crucial for equitable and effective T2D prevention.
- Continued development and implementation of evidence-based T2D prevention strategies are needed worldwide.
