Correlation of bone mineral density assessed using quantitative CT with obesity indicators, blood pressure, platelet count, and blood lipids in perimenopausal women

• In perimenopausal women, quantitative CT bone mineral density is negatively correlated with abdominal obesity indicators (waist circumference, body shape index, taper index) and positively correlated with platelet count after adjusting for confounders. • No significant correlation was found between bone mineral density and blood pressure, blood lipids, or fasting blood glucose in this population. • Body shape index and taper index showed the strongest correlations with bone mineral density among abdominal obesity indicators, suggesting their potential as clinical markers. • The study provides evidence for early prevention of osteoporosis in perimenopausal women, but future prospective multi-center studies are needed to confirm findings.
