Physical activity in children and adolescents with cystic fibrosis: A systematic review and meta-analysis.

BACKGROUND: Exercise and physical activity (PA) are essential components of the care of cystic fibrosis (CF) patients. Lower PA levels have been associated with worse pulmonary function, aerobic fitness, glycemic control, and bone mineral density. Most people with CF do not engage in the recommended amounts of PA. OBJECTIVE: To determine the level of PA in children and adolescents with CF. METHODS: A systematic review with meta-analysis was conducted without language restrictions in five databases. Were included studies that analyzed PA measured by objective and subjective instruments in children and adolescents with CF. Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of evidence. The risk of bias of the included studies was assessed with the National Heart, Lung, and Blood Institute's risk-of-bias tool. RESULTS: Of the 1535 reports returned by the initial search, 20 articles reporting on 785 patients were included in the data synthesis. The forest plot showed that the CF group had a similar moderate-to-vigorous PA (MVPA) (mean difference, -7.79; 95% CI -15.65 to 0.08 min/d; P = .05) and sedentary time (mean difference, -50.81; 95%CI, -109.96 to 8.35 min/d; P = .09) to the control group. CONCLUSION: Children and adolescents with CF have a similar MVPA and sedentary time compared to controls. There are many options, subjective and objective, for assessing PA in this population. Optimal tool selection should guarantee more valid results.

Perceptions of the educational environment among undergraduate physical therapy students in a competency-based curriculum at the University of Chile.

PURPOSE: This study aimed to assess the educational environment (EE) among students in a physical therapy undergraduate program, to identify patterns in EE perceptions among the students by year, and to determine issues that should be addressed. METHODS: The Dundee Ready Education Environment Measure (DREEM) questionnaire was used to explore the relationships among the total mean score, subscales, and items in a competency-based curriculum in the physical therapy program at the University of Chile. The DREEM questionnaire was filled out by 166 of 244 students (68.03%), of whom 56.6% were men and 43.4% were women, with 75.9% between 19 and 23 years of age. RESULTS: The total mean score (120.9/200) indicated that the EE was perceived as 'more positive than negative.' There were significant differences (P<0.05) between first-year students (113.41), who reported the lowest total mean score, and fourth-year students (126.60), who had the highest total mean score. Students rated their EE favorably on each subscale except social self-perceptions, which second-year students rated as 'not too bad,' and for which first-, third-, and fourth-year students gave a rating corresponding to 'not a nice place.' On the perceptions of teachers subscale, there were significant differences (P<0.05) between first-year students (28.05/44) and fourth-year students (32.24/44) and between second-year students (28.72/44) and fourth-year students (32.24/44). On the academic self-perceptions subscale, there were significant differences (P<0.05) between first-year students (18.12/32) and second-year (21.68/32), third-year (22.33/32), and fourth-year students (21.87/32). CONCLUSION: Physical therapy students at the University of Chile had positive perceptions of their EE. First-year students rated the largest number of items as problematic. Improvements are required across the program in the specific subscales mentioned above.
