Nutritional status of pneumoconiosis patients complicated with spontaneous pneumothorax and its influence on disease progress

  Objective  To analyze the general clinical indicators and related nutritional status of pneumoconiosis patients complicated with spontaneous pneumothorax, and to explore the main influencing factors of pneumoconiosis patients complicated with spontaneous pneumothorax.

  Methods  A total of 114 patients with pneumoconiosis admitted from 2016 to 2020 were retrospectively analyzed. They were divided into pneumoconiosis complicated with spontaneous pneumothorax group(n = 30)and simple pneumoconiosis group (n = 84). The body mass index(BMI), hemoglobin, cholesterol, triglycerides, blood glucose, serum albumin and other nutritional status of the patients in two groups were compared.

  Results  The BMI and serum albumin levels of pneumoconiosis patients complicated with spontaneous pneumothorax were(19.31 ± 2.88) kg/m² and(36.95 ± 4.28)g, respectively, which were lower than those of patients with simple pneumoconiosis(22.96 ± 3.43) kg/m² and (40.39 ± 4.33) g (P < 0.01). The multivariate logistic analysis showed that older age (OR = 0.803), higher BMI (OR = 0.534), higher serum albumin(OR = 0.546) and longer average course of disease(OR = 0.369) were protective factors fhorax； the third stage of pneumoconiosis (OR = 126.914) was the risk factor of spontaneous pneumothorax in pneumoconiosis patients.

  Conclusions  Pneumoconiosis patients should strengthen their protein nutrition supplement at ordinary times, which could reduce the possibility of pneumothorax in pneumoconiosis patients.
