Prevalence of hypertension determined by ambulatory blood pressure monitoring (ABPM) and body composition in long-term survivors of childhood cancer

ABSTRACT

Aim: In recent years, survival rates of childhood cancers have significantly increased, and occurrence of long-term adverse late effects (eg, insulin resistance, diabetes mellitus, metabolic syndrome, hypertension) has become increasingly important. Early diagnosis of obesity/hypertension in childhood is essential to avoid morbidity in the adulthood. Therefore, this study was aimed to determine the blood pressure (BP) profile by ambulatory BP monitoring (ABPM) method, and prevalence of hypertension, obesity, abdominal obesity among childhood cancer survivors. Material and method: The study was carried out with 52 cancer survivors. The ABPM measurement was performed during 24 hours. The anthropometric measurements of patients were performed using standardized protocols. The body composition analysis was performed with bioelectrical impedance analysis (BIA) method. Statistical significance was considered at p < 0.05. Results: The mean age of patients was 12.84 ± 3.88 years. Time off therapy ranged 24–125 month. The prevalence of prehypertension and hypertension were 57.7% and 9.6%, respectively. There was no statistically significant relationship between diagnosis and BP status (p = 0.59). The prevalence of obesity, and abdominal obesity were 1.9% and 30.4%, respectively. There was a positive correlation between waist circumference (WC) and time off therapy (p = 0.046). The WC was found to be higher in patients who received cranial irradiation (p = 0.048). Weight/WC were higher in patients who used corticosteroids in the treatment (p = 0.019). Conclusion: Careful follow up of BP, weight and WC is necessary for long-term cancer survivors to prevent complications. Especially patients who receive cranial radiotherapy and use corticosteroid are at increased risk of abdominal obesity.
