The UPHILL study: A nutrition and lifestyle intervention to improve quality of life for patients with pulmonary arterial hypertension

Abstract

Abstract The aim of the UPHILL study (a nutrition and lifestyle intervention in patients with pulmonary arterial hypertension [PAH]: effect on quality of life [QoL]), was to determine the effect of innovative nutritional interventions on adjustments in nutritional intake and QoL. In this study a group of prevalent PAH patients at a single center in Amsterdam (the Netherlands) was informed about healthy nutrition using a newly designed video e‐learning. They were subsequently instructed to follow a healthy diet during dietary intervention. Nutritional intake was assessed using a food frequency questionnaire (HELIUS) and QoL by the short‐form (SF)‐36 questionnaire. Nutritional parameters were determined in blood samples. Seventeen patients stable under treatment, who had been diagnosed with PAH 7.0 [3.0−14.0] years before, started and completed the intervention (2 males, 15 females; 45.35 ± 13.57 years). Since all patients in the intervention group made behavioral changes in nutritional intake, during study and follow‐up, nutritional and lifestyle adaptations persisted. Despite the fact that patients had already high mean scores at baseline for both mental (74.10 [60.51−84.25]) and physical QoL (66.46 [50.21−73.84]), scores improved further during e‐learning. Furthermore, patients who realized most nutritional adaptations, had the best improvement in QoL. This pilot study showed that e‐learning modules on nutrition provide an unique opportunity to change nutritional intake in PAH patients and by that improve QoL.
