Study Notes
Diabetes Epidemiology Study in Shenyang, China
- Study Type: Cross-sectional epidemiological survey
- Participants: People aged 40 years and older in Shenyang, China
- Sample Size: 3922 respondents, 609 with diabetes
- Prevalence: 15.5% prevalence of diabetes
- Rural vs. Urban: Higher prevalence in rural areas (17.7%) compared to urban areas (14.2%)
- Gender Differences: No significant difference in prevalence between men and women (14.8% vs. 16.1%)
- Risk Factors: Advanced age, hypertension, and dyslipidemia were identified as influencing factors.
-
Awareness, Treatment, and Control Rates:
- Awareness: 82.3%
- Treatment: 36.6%
- Control of fasting plasma glucose: 17.1%
- Awareness rates were higher in men in different age groups. Treatment rates were higher in women.
Case-Control Study of Type 2 Diabetes Risk Factors (Japan)
- Study Type: Case-control study
- Focus: Association between physical activity and type 2 diabetes
- Participants: Middle-aged Japanese (53.5±6.8 years old). Included cases of type 2 diabetes, dyslipidemia alone, comorbidity, and controls.
- Methods: Self-administered questionnaires, including Baecke's questionnaire (to assess physical activity) and data on other lifestyle factors.
- Findings: Physical activity was negatively associated with the risk of type 2 diabetes and the comorbidity of type 2 diabetes and dyslipidemia. The odds ratio of the fourth quartile to lowest level was 0.31 (for type 2 diabetes) and 0.32 (for comorbidity)
- Conclusion: Physical activity was associated with reduced type 2 diabetes and comorbidity, particularly in the context of sex and age.
Prospective Cohort Study of Type 2 Diabetes and Parkinson's Disease Risk
- Study Type: Prospective cohort study
- Participants: 21,841 U.S. male physicians
- Objective: To evaluate the association between type 2 diabetes and Parkinson's disease
- Duration: 23 years of follow-up
-
Results:
- Increased risk of Parkinson's disease among individuals with diabetes (multivariable-adjusted RR = 1.34) after adjusting for potential confounders like vascular disease.
- Association remained significant even after excluding those with known vascular disease.
- Diabetes diagnosis was often close in time to Parkinson's disease diagnosis, particularly in men with short duration of diabetes and no diabetes complications.
- Conclusion: The findings do not suggest that diabetes precedes Parkinson's disease in this specific population.
