Abstract

Objective: To evaluate the relationship between screen time (ST) and lung function in hospitalized children and adolescents with cystic fibrosis (CF).

Methods: This was a cross-sectional study of 45 children with CF in the 0- to 17-year age bracket admitted to a public hospital in southern Brazil. ST during hospitalization was measured by means of a recall diary. Questionnaires were used in order to collect data on screen use and personal data. Data on lung function, nutrition, bacteriology, and the Shwachman-Kulczycki clinical score were obtained from patient medical records.

Results: Of the study participants, 51.1% were male, with a median age of 9 years, and 80% were White. The mean FEV1 (Z-score) was -2.9 ± 1.9, and FEV1 (in % of predicted) was 63.7 ± 22.3. The median ST was 315 min, and 95.5% of the study participants exceeded the recommended ST. The most prevalent reasons for using electronic devices during hospitalization were boredom and lack of other activities. In a multivariate analysis, ST (the dependent variable) was significantly associated with age (b = 26.591; 95% CI, 14.695-38.487), time spent watching television at home (b = 0.686; 95% CI, 0.304-1.069), and FEV1 Z-score (b = -60.631; 95% CI, -115.399 to -5.864).

Conclusions: Excess ST appears to be associated with worse lung function in hospitalized children with CF, as do older age and longer periods of time spent watching television at home.

囊性纤维化住院儿童筛查时间与肺功能的关系

目的：探讨住院儿童和青少年囊性纤维化（CF）筛查时间与肺功能的关系。方法：对巴西南部一家公立医院收治的45名0- 17岁CF患儿进行横断面研究。住院期间的ST采用回忆日记的方式测量。问卷调查是为了收集屏幕使用情况和个人数据。肺功能、营养、细菌学和Shwachman-Kulczycki临床评分数据从患者病历中获得。结果：研究参与者中，51.1%为男性，中位年龄为9岁，80%为白人。平均FEV1 （Z-score）为-2.9±1.9,FEV1（预测的%）为63.7±22.3。中位ST为315分钟，95.5%的研究参与者超过了推荐ST。住院期间使用电子设备最普遍的原因是无聊和缺乏其他活动。在多变量分析中，ST（因变量）与年龄（b = 26.591; 95% CI, 14.695-38.487）、在家看电视时间（b = 0.686; 95% CI, 0.304-1.069）和FEV1 Z-score （b = -60.631; 95% CI, -115.399至-5.864）显著相关。结论：在CF住院儿童中，ST段过多似乎与肺功能恶化有关，与年龄较大和在家看电视时间较长有关。
