Skin diseases in the Da Qing Diabetes Study: a cross-sectional study.

Area of Science:

• Dermatology
• Endocrinology
• Public Health

Background:

• Skin diseases and diabetes mellitus (DM) are globally prevalent health issues.
• Limited understanding exists regarding the prevalence and specific comorbidities of skin diseases in type 2 diabetes mellitus (T2DM).

Purpose of the Study:

• To investigate the prevalence and clinical characteristics of skin diseases in individuals with varying glucose tolerance statuses, including normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and T2DM.
• To identify specific skin conditions associated with T2DM and explore correlations with disease duration and demographic factors.

Main Methods:

• A cross-sectional study involving 383 participants from the Da Qing Diabetes Study (2016).
• Participants were categorized into NGT, IGT, and T2DM groups.
• Prevalence and clinical characteristics of skin diseases were systematically recorded and analyzed.

Main Results:

• Overall skin disease prevalence was 93.5%, with 75.7% having multiple conditions.
• Significant differences in "disturbances of pigmentation" and "neurological and psychogenic dermatoses" were observed between glucose tolerance groups.
• T2DM duration was associated with "disturbances of pigmentation" and "neurological and psychogenic dermatoses"; "disturbances of pigmentation" were more prevalent in males and differed significantly between NGT and T2DM groups.

Conclusions:

• The Da Qing Diabetes Study revealed a high prevalence of skin diseases across all glucose tolerance categories.
• Targeted awareness and intervention strategies are crucial for managing dermatological conditions in individuals with T2DM.
