Early-onset diabetes: an epidemic in China

Jiemin Pan, Weiping Jia

Frontiers of Medicine 2018, Volume 12, Issue 6,   Pages 624-633 doi: 10.1007/s11684-018-0669-1

Abstract:

Although type 2 diabetes is a disease often associated with aging, the global prevalence of early-onset diabetes has been increasing due to man’s sedentary lifestyle, low-physical activity, obesity, and some non-modifiable risk factors. Many studies have found that individuals with early-onset type 2 diabetes were at higher risk of developing vascular complications than those with late-onset diabetes. Individuals with early-onset diabetes are usually unwilling to visit hospital and have more confidence in their health, which results in poor glycemic control and the delayed detection of diabetes-related complications. Few studies have focused on the treatment and prevention of complications in specific population of individuals with early-onset type 2 diabetes. Therefore, focusing on this particular population is critical for the government and academic societies. Screening for T2DM is imminent for young adults with a family history of diabetes, obesity, markers of insulin resistance, or alcohol consumption. More data are definitely required to establish a reasonable risk model to screen for early-onset diabetes.

The epidemic status and risk factors of lung cancer in Xuanwei City, Yunnan Province, China

Yize Xiao, Ying Shao, Xianjun Yu, Guangbiao Zhou

Frontiers of Medicine 2012, Volume 6, Issue 4,   Pages 388-394 doi: 10.1007/s11684-012-0233-3

Abstract:

Xuanwei City (formerly known as Xuanwei County) locates in the northeastern of Yunnan Province and is rich in coal, iron, copper and other mines, especially the smoky (bituminous) coal. Unfortunately, the lung cancer morbidity and mortality rates in this region are among China’s highest, with a clear upward trend from the mid-1970s to mid-2000s. In 2004–2005, the crude death rate of lung cancer was 91.3 per 100 000 in the whole Xuanwei City, while that for Laibin Town in this city was 241.14 per 100 000. The epidemiologic distribution (clustering patterns by population, time, and space) of lung cancer in Xuanwei has some special features, e.g., high incidence in rural areas, high incidence in females, and an early age peak in lung cancer deaths. The main factor that associates with a high rate of lung cancer incidence was found to be indoor air pollution caused by the indoor burning of smoky coal. To a certain extent, genetic defects are also associated with the high incidence of lung cancer in Xuanwei. Taken together, lung cancer in this smoky coal combustion region is a unique model for environmental factor-related human cancer, and the current studies indicate that abandoning the use of smoky coal is the key to diminish lung cancer morbidity and mortality.
