OBJECTIVE Few studies are currently available regarding the influence of sleep duration on glycemic control in diabetic patients. The objective of the current study was to examine the relationship between sleep duration, obesity, and the glycemic level in type 2 diabetic patients. RESEARCH DESIGN AND METHODS A total of 4,870 Japanese type 2 diabetic(More)
Medical nutrition therapy plays a critical role in the prevention and treatment of type 2 diabetes. However, appropriate measures of eating behaviours, such as eating rate, have not yet been clearly established. The aim of the present study was to examine the associations among eating rate, obesity and cardiovascular risk factors. A total of 7,275 Japanese(More)
OBJECTIVE Sleep duration is suggested to be associated with adverse health outcomes. However, few studies are available on the impact of sleep duration on metabolic syndrome in patients with diabetes, who were at high risk for cardiovascular diseases (CVD). The objective of the present study was to examine the associations of sleep duration with metabolic(More)
OBJECTIVE Few studies have so far investigated the impact of sleep duration on chronic kidney disease in diabetic patients. The objective of the present study was to examine the relationship between sleep duration and albuminuria in type 2 diabetic patients. RESEARCH DESIGN AND METHODS A total of 4,870 Japanese type 2 diabetic patients ≥20 years of age(More)
Aldehyde dehydrogenase 2 (ALDH2) detoxifies aldehyde produced during ethanol metabolism and oxidative stress. A genetic defect in this enzyme is common in East Asians and determines alcohol consumption behaviors. We investigated the impact of genetically determined ALDH2 activity on diabetic microvascular and macrovascular complications in relation to(More)
BACKGROUND Dietary fiber is beneficial for the treatment of type 2 diabetes mellitus, although it is consumed differently in ethnic foods around the world. We investigated the association between dietary fiber intake and obesity, glycemic control, cardiovascular risk factors and chronic kidney disease in Japanese type 2 diabetic patients. METHODS A total(More)
OBJECTIVE Cigarette smoking is an important modifiable risk factor for cardiovascular diseases. However, the effect of smoking and its cessation on glycemic control in diabetic patients has not been fully examined yet. The aim of the present study was to examine the association of smoking status with glycemic level and markers of insulin resistance and(More)
AIMS/HYPOTHESIS The effects of leisure-time physical activity (LTPA) on glycemia and cardiovascular risk factors are not fully understood in Asian type 2 diabetic patients, who are typically non-obese. We studied associations between LTPA and glycemia and cardiovascular risk factors in Japanese type 2 diabetic patients. METHODS A total of 4,870 Japanese(More)
OBJECTIVE Although many studies have investigated the clinical characteristics of patients with diabetes with depression in Western populations, there is a lack of information regarding other ethnicities. We studied the association between clinical characteristics and depressive symptoms in Japanese patients with type 2 diabetes. METHODS A total of 4218(More)
RESULTSdThe HbA1c levels showed a quadratic association with sleep duration; namely, a shorter or longer sleep duration was associated with a higher level compared with a sleep duration of 6.5–7.4 h (P for quadratic trend ,0.001). This association remained significant after adjusting for potential confounders, including the total energy intake and(More)
