No associations exist between mean platelet volume or platelet distribution width and thyroid function in Chinese.

Area of Science:

• Endocrinology
• Hematology
• Public Health

Background:

• Platelet indices, including mean platelet volume (MPV) and platelet distribution width (PDW), reflect platelet characteristics.
• Thyroid dysfunction is a prevalent endocrine disorder with potential systemic implications.
• Understanding relationships between platelet indices and thyroid function may offer insights into disease mechanisms.

Purpose of the Study:

• To investigate the association between MPV and PDW with thyroid function.
• To evaluate the diagnostic value of MPV and PDW for thyroid dysfunction in a large Chinese population.

Main Methods:

• Cross-sectional study of 13,622 healthy Chinese adults.
• Analysis of anthropometric data, laboratory markers including MPV, PDW, and thyroid hormones.
• Statistical analysis using ANOVA, t-tests, ROC curves, and logistic regression models.

Main Results:

• MPV and PDW were higher in females, who also had a higher incidence of thyroid dysfunction.
• No significant differences in MPV or PDW were observed across different thyroid function subgroups.
• MPV and PDW showed no correlation with thyroid function and lacked diagnostic value for thyroid dysfunction.

Conclusions:

• This study did not establish a link between MPV or PDW and thyroid function in the studied cohort.
• Further prospective studies are recommended to explore potential associations in specific risk groups.
