Association of serum calcium level with waist circumference and other biochemical health-care predictors among patients with type 2 diabetes

Abstract

Introduction: This study aimed to find the association of serum calcium level with abdominal obesity according to the waist circumference (WC) and the associated factors. Materials and Methods: A cross-sectional study was carried out at private health-care center. A total of 291 patients, aged 18 years and above, with type 2 diabetes mellitus who attended the clinic from May 2017 through March 2018 were included. Sociodemographic, clinical, and laboratory data were obtained from the medical records of patients. Statistical analysis was carried out using the Statistical Package for the Social Sciences software (SPSS, version 23). Abdominal obesity was defined by WC ≥ 80cm in women and ≥94cm in men. Results: A total number of 291 participants participated in the study. Among these participants, 42.6% (n = 124) were male and 57.4% (n = 167) were female. The average age of respondents was 55.99 ± 9.81 years. Among the male participants, 90 (72.6%) (95% confidence interval [CI]: 64.6%–80.5%) were abdominally obese as were 154 participants (92.2%) (95% CI: 88.1%–96.3%) among females. Overall, 244 participants (83.8%) (95% CI: 79.6%–88.1%) were abdominally obese. The results of statistical modeling showed that gender, smoking status, physical activity, and serum calcium are strong determinants of abdominal obesity. Conclusion: This study revealed a significant association of abdominal obesity and serum calcium level among patients with diabetes.
