BACKGROUND Intensive lifestyle interventions can reduce the incidence of type 2 diabetes in people with impaired glucose tolerance, but how long these benefits extend beyond the period of active intervention, and whether such interventions reduce the risk of cardiovascular disease (CVD) and mortality, is unclear. We aimed to assess whether intensive(More)
BACKGROUND Lifestyle interventions among people with impaired glucose tolerance reduce the incidence of diabetes, but their effect on all-cause and cardiovascular disease mortality is unclear. We assessed the long-term effect of lifestyle intervention on long-term outcomes among adults with impaired glucose tolerance who participated in the Da Qing Diabetes(More)
OBJECTIVE Despite its growing prevalence in China, the extent to which diabetes leads to excess cardiovascular disease (CVD) mortality and all-cause mortality is unclear. RESEARCH DESIGN AND METHODS We compared death rates and causes of death among 630 people with newly diagnosed diabetes (NDD) and 519 with normal glucose tolerance (NGT) who, in 1986,(More)
OBJECTIVE To investigate the effects of insulin resistance (IR) and insulin secretion (IS) on the development of diabetes mellitus in individuals with impaired glucose tolerance (IGT) who underwent lifestyle interventions. METHODS 284 out of 577 individuals with IGT identified by population-based screening in Da Qing, China, who were randomized to undergo(More)
OBJECTIVE People with impaired glucose tolerance (IGT) have increased risk of mortality and a high risk of progression to diabetes, but the extent that the excess mortality is associated with IGT per se or is the result of subsequent diabetes is unclear. RESEARCH DESIGN AND METHODS We compared mortality before and after the development of diabetes among(More)
Dichromatic vision is due to the loss of one of the three cone pigments: the L type in protanopes, the M type in deuteranopes, and the S type in tritanopes. In this paper, we show that the dichromatic vision can be simulated by applying transformation to image in CIE x, y chromaticity space. We base our work on the past experiments on unilateral color blind(More)
OBJECTIVE To investigate if a six-year intensive lifestyle intervention in people with pre-diabetes lead to reduction of cardiovascular events and cardiovascular disease (CVD) mortality in subsequent 23 years. METHODS Five hundreds and nineteen subjects with normal glucose tolerance (NGT) and 577 subjects with impaired glucose tolerance (IGT) in Da Qing(More)
