Reproductive factors predict risks of cardiovascular disease and premature death in postmenopausal women with type 2 diabetes: The Fukuoka Diabetes Registry.

Aims: Reproductive factors (reproductive period, age at menarche, and age at menopause) are associated with a risk of cardiovascular disease (CVD) and death in individuals without focusing on comorbid diabetes. However, it remains unclear whether this association also applies to individuals with diabetes. This study investigated the relationship between reproductive factors and the risk of CVD and death in postmenopausal Japanese women with type 2 diabetes.

Sleep duration and its association with constipation in patients with diabetes: The fukuoka diabetes registry.

Aims: Shorter and longer sleep durations are associated with adverse health consequences. However, available evidence on the association of sleep duration with constipation is limited, especially in patients with diabetes, who are at a high risk of both conditions. This study aimed to examine the association between sleep duration and constipation in patients with type 2 diabetes.

The objective of the present study was to examine the association between constipation and diabetic kidney disease (DKD).

Methods: In total, 4826 Japanese outpatients with type 2 diabetes were classified according to presence or absence of constipation (defecation frequency < 3 times/week and/or taking laxative medication).

Defecation frequency and glycemic control in patients with diabetes: The Fukuoka Diabetes Registry.

Aims: Constipation has been shown to be associated with a higher risk of diabetes.

Aims/hypothesis: Serum adiponectin has been reported to impact upon fracture risk in the general population. Although type 2 diabetes is associated with increased fracture risk, it is unclear whether serum adiponectin predicts fractures in individuals with type 2 diabetes. The aim of the study was to prospectively investigate the relationship between serum adiponectin and fracture risk in individuals with type 2 diabetes.

Joint impact of modifiable lifestyle behaviors on glycemic control and insulin resistance in patients with type 2 diabetes: the Fukuoka Diabetes Registry.

Background: There is little information about the predictive ability of cystatin C-based estimated glomerular filtration rates (eGFR) for all-cause mortality in Asian populations. We compared the discriminatory ability of eGFR for all-cause mortality with that of creatinine-based estimated glomerular filtration rates (eGFR) in Japanese patients with type 2 diabetes.

Methods: A total of 4869 participants were classified into four categories (eGFR ≤29, 30-59, 60-89, and ≥90 ml/min/1.

Effects of smoking and its cessation on creatinine- and cystatin C-based estimated glomerular filtration rates and albuminuria in male patients with type 2 diabetes mellitus: the Fukuoka Diabetes Registry.

Cigarette smoking is an important modifiable risk factor for lifestyle diseases. The smoking rate remains high, and the prevalence of diabetes mellitus is increasing in Asian countries; however, few studies have examined the effects of smoking on chronic kidney disease (CKD) in Asian diabetic patients. The aim of the present study was to investigate the association between smoking and its cessation with CKD and its components in patients with type 2 diabetes.
