Objectives: This study aimed to determine which factors are associated with HbA1c levels among residents of Choshi City in Chiba, Japan.
Methods: We recruited 372 (age, 20−39 y) of 492 women who underwent a medical examination in Choshi City during 2015. Body composition, physical activity and serum adiponectin (Ad) values were measured.
Results: Among the participants, 155 (42%) women who had high HbA1c values (≥ 5.6%) weighed significantly more, had a significantly higher BMI and abdominal circumference, as well as serum LDL-Chol and TG values, and lower hemoglobin, HDL-Chol and Ad values than those with normal HbA1c. The women with high HbA1c had significantly more abnormal serum lipid and hemoglobin values that increased their risk for hyperlipidemia and anemia. High HbA1c levels were also associated with weight gain (>10 kg compared with weight at the age of 20 years) and less alcohol consumption and skipping breakfast.
Conclusion: Weight gain and dietary habits are associated with HbA1c levels.
