- Effects of a behaviour change intervention aimed at increasing physical activity on clinical control of adults with asthma: study protocol for a randomised controlled trial(2019) FREITAS, Patricia D.; XAVIER, Rafaella F.; PASSOS, Natalia F. P.; CARVALHO-PINTO, Regina M.; CUKIER, Alberto; MARTINS, Milton A.; CAVALHERI, Vinicius; HILL, Kylie; STELMACH, Rafael; CARVALHO, Celso R. F.Background: In adults with asthma, physical activity has been associated with several asthma outcomes. However, it is unclear whether changes in physical activity, measured via an accelerometer, have an effect on asthma control. The objective of the present study is, in adults with moderate-to-severe asthma, to investigate the effects of a behaviour change intervention, which aims to increase participation in physical activity, on asthma clinical control. Methods: This is a single-blind (outcome assessor), two-arm, randomised controlled trial (RCT). Fifty-five participants with moderate-to-severe asthma, receiving optimized pharmacological treatment, will be randomly assigned (computer-generated) into either a Control Group (CG) or an Intervention Group (IG). Both groups will receive usual care (pharmacological treatment) and similar educational programmes. In addition to these, participants in the IG will undergo the behaviour change intervention based on feedback, which aims to increase participation in physical activity. This intervention will be delivered over eight sessions as weekly one-on-one, face-to-face 40-min consultations. Both before and following the completion of the intervention period, data will be collected on asthma clinical control, levels of physical activity, health-related quality of life, asthma exacerbation and levels of anxiety and depression symptoms. Anthropometric measurements will also be collected. Information on comorbidities, lung function and the use of asthma medications will be extracted from the participant's medical records. Discussion: If successful, this study will demonstrate that, in adults with asthma, a behavioural change intervention which aims to increase participation in physical activity also affects asthma control.
- Characterization and association between fat mass and fat-free mass ratio with clinical characteristics in asthmatic adults(2021) ALVES, Thaina Bessa; RUGILA, Diery Fernandes; CAVALLARI, Felipe Vilaca; OLIVEIRA, Joice Mara; CORREIA, Natielly Soares; PASSOS, Natalia Febrini Piassi; FREITAS, Patricia Duarte; PITTA, Fabio; CARVALHO, Celso Ricardo Fernandes; FURLANETTO, Karina Couto

- Fat mass to fat-free mass ratio and its associations with clinical characteristics in asthma(2022) RUGILA, Diery Fernandes; OLIVEIRA, Joice Mara; MACHADO, Felipe Vilaca Cavallari; CORREIA, Natielly Soares; PUZZI, Vitoria Cavalheiro; PASSOS, Natalia Febrini Piassi; FREITAS, Patricia Duarte; PITTA, Fabio; CARVALHO, Celso Ricardo Fernandes; FURLANETTO, Karina CoutoBackground: Fat mass to fat-free mass ratio (FM/FFM) assesses the combined effect of the balance between fat mass and fat-free mass. Aims: to evaluate the associations beetween FM/FFM and clinical outcomes in asthma and to compare clinical characteristics between individuals with higher and lower FM/FFM. Methods: 128 participants with asthma underwent anthropometric, spirometry and bioelectrical impedance assessments. Physical activity in daily life (PADL) was assessed by the Actigraph for 7 days. Daily dose of inhaled medication, steps of pharmacological treatment, Asthma Control Questionnaire, Asthma Quality of Life Questionnaire and Hospital Anxiety and Depression Scale were also assessed. Participants were classified into two groups according to the 50th percentile of reference values for FM/FFM. Results: Individuals with higher FM/FFM (n=75) used higher daily doses of inhaled corticosteroids, had worse lung function and fewer steps/day when compared to those with lower FM/FFM (n=53) (P <= 0.021). Associations were found between absolute values of FM/FFM with lung function (FEV1 and FVC [liters]): R-2=0.207 and 0.364;P<0.0001), and between the categories of lower or higher FM/FFM with steps of medication treatment (Cramer's V=0.218;P=0.016) and level of PADL (Cramer's V=0.236;P=0.009). The highest FM/FFM was a determining factor of physical inactivity (OR: 3.21;95%CI:1.17-8.78) and highest steps of pharmacological treatment (OR: 8.89;95%CI:1.23-64.08). Conclusion: Higher FM/FFM is significantly associated with worse clinical characteristics in individuals with asthma, such as higher doses of inhaled corticosteroids, worse lung function and fewer steps/day. Moreover, higher FM/FFM is a determining factor of physical inactivity and the highest steps of pharmacological treatment for asthma.
- Identification of asthma phenotypes based on extrapulmonary treatable traits(2021) FREITAS, Patricia Duarte; XAVIER, Rafaella Franca; MCDONALD, Vanessa Marie; GIBSON, Peter Gerard; CORDOVA-RIVERA, Laura; FURLANETTO, Karina Couto; OLIVEIRA, Joice Mara de; CARVALHO-PINTO, Regina Maria; CUKIER, Alberto; STELMACH, Rafael; CARVALHO, Celso Ricardo FernandesAsthma is a heterogeneous and complex disease, and a description of asthma phenotypes based on extrapulmonary treatable traits has not been previously reported. The objective of this study was to identify and characterise clusters based on clinical, functional, anthropometrical and psychological characteristics in participants with moderate-to-severe asthma. This was a cross-sectional multicentre study involving centres from Brazil and Australia. Participants (n=296) with moderate-to-severe asthma were consecutively recruited. Physical activity and sedentary time, clinical asthma control, anthropometric data, pulmonary function and psychological and health status were evaluated. Participants were classified by hierarchical cluster analysis and the clusters compared using ANOVA, Kruskal Wallis and Chi-squared tests. Multiple logistic and linear regression models were performed to evaluate the association between variables. We identified four clusters: 1) participants with controlled asthma who were physically active, 2) participants with uncontrolled asthma who were physically inactive and more sedentary; 3) participants with uncontrolled asthma and low physical activity, who were also obese and experienced anxiety and/or depression symptoms; and 4) participants with very uncontrolled asthma who were physically inactive, more sedentary, obese and experienced anxiety and/or depression symptoms. Higher levels of sedentary time, female sex and anxiety symptoms were associated with increased odds of exacerbation risk, while being more active showed a protective factor for hospitalisation. Asthma control was associated with sex, the occurrence of exacerbation, physical activity and health status. Physical inactivity, obesity and symptoms of anxiety and/or depression were associated with worse asthma outcomes, and closely and inextricably associated with asthma control. This cluster analysis highlights the importance of assessing extrapulmonary traits to improve personalised management and outcomes for people with moderate and severe asthma.
