Introduction

Secondary hyperparathyroidism (SHPT) is a common complication in patients with end-stage kidney disease (ESKD) on hemodialysis (HD). Obesity has been associated with altered mineral metabolism and elevated PTH levels. However, data on the relationship between body mass index (BMI) and PTH in Mexican HD patients is lacking.

Methods

A prospective, cross-sectional, observational and analytical study was conducted at a tertiary referral center in Ciudad Obregón, Mexico, from June to October 2023. We included 188 adult patients undergoing HD for ≥3 months. Anthropometric measurements (weight and height) and serum iPTH levels were obtained. Correlation between iPTH and BMI was analyzed using Pearson and Spearman correlation tests. A p-value ≤0.05 was considered statistically significant.

Results

Correlation between BMI and iPTH Scatter plot

BMI disctribution by categories Among 188 patients (mean age 57.5 ± 13.9 years; 51.1% female), mean BMI was 27.01 ± 5.99 kg/m². The distribution of BMI was: 40.4% normal weight, 31.4% overweight, 25% obese, and 3.2% underweight. Mean iPTH was 580.89 ± 576.77 pg/mL. A weak but statistically significant positive correlation was found between BMI and iPTH (Pearson r = 0.126, p = 0.043; Spearman rho = 0.143, p = 0.025). No significant differences in iPTH levels were observed when comparing BMI groups (p = 0.211).

Conclusion

Our findings indicate a weak positive correlation between BMI and iPTH levels in chronic HD patients. Although statistically significant, this association may lack clinical relevance. Further studies incorporating additional confounders (e.g., diet, physical activity, vitamin D status) and serial PTH measurements are needed to elucidate this relationship and guide SHPT management strategies in obese HD patients.
