[Exploratory study on the association between high iodine intake and lipid]

Area of Science:

• Environmental Health
• Biochemistry
• Epidemiology

Context:

• Iodine is an essential nutrient, but excessive intake can have adverse health effects.
• Lipid disorders are a significant risk factor for cardiovascular diseases.
• The relationship between excessive iodine intake and lipid profiles requires further investigation.

Purpose:

• To investigate the association between excessive iodine intake from drinking water and the prevalence of lipid disorders.
• To compare lipid profiles and the rates of abnormal lipid indicators between individuals with excessive and normal iodine intake.

Summary:

• This study compared lipid profiles (including TG, TC, HDL-C, LDL-C, apoA1, apoB) in residents with excessive iodine intake versus normal iodine intake.
• Results showed significantly lower apolipoprotein A1 (apoA1) and a higher abnormal rate of high-density lipoprotein cholesterol (HDL-C) in the excessive iodine group.
• Both apoA1 and HDL-C demonstrated a negative correlation with water iodine levels in the excessive intake group.

Impact:

• Excessive iodine intake may be a risk factor for developing lipid disorders.
• Findings highlight the potential public health implications of iodine levels in drinking water.
• This research contributes to understanding the complex interplay between environmental factors and metabolic health.
