Abstract:
BACKGROUND:Few studies have examined the relationship of one's habitual physical activity level and autonomic nervous system (ANS) modulation on sleep quality in smokers. OBJECTIVE:The aim of this study was to identify changes in the sleep quality of smokers and its relation with their habitual physical activity level and ANS modulation. METHODS:Forty-two smokers were divided into two groups according to the 50th percentile of the moderate-to-vigorous physical activity (MVPA). Sleep quality was assessed using the Mini-sleep Questionnaire, and ANS modulation was assessed by indices of heart rate variability (HRV). To examine the possible mean differences, the analysis of covariance (ANCOVA) was used, adjusted for age, sex, body composition, pack-years, beta-blockers, anxiety, and depression in log base 10, not including qualitative data, such as sex and beta-blockers. Correlations were made by using the Spearman rank correlation. The statistical significance was set at 5. RESULTS:The smokers who were less active showed poor sleep quality (p=0.048) and insomnia (p=0.045). Furthermore, the less active group presented decreased parasympathetic modulation [HF (un; p=0.049); RMSSD (ms; p=0.047) and SD1 (ms; p=0.047)] and an increased LF (un) index (p=0.033) and LF/HF ratio (p=0.040). A positive correlation between the total Mini-sleep score with LF (un) index (r=0.317, p=0.041) and LF/HF ratio (r=0.318, p=0.040) and negative correlation with HF (un) index (r= -0.322, p=0.038). CONCLUSIONS:Smokers with lower levels of habitual physical activity showed poor sleep quality and alterations in autonomic nervous system modulation; (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0). FUNDAMENTO:Poucos estudos já examinaram a relação do nível habitual de atividade física e a modulação do sistema nervoso autônomo (SNA) na qualidade do sono de fumantes. OBJETIVOS:O objetivo deste estudo foi identificar alterações na qualidade do sono de fumantes e sua relação com nível habitual de atividade física e modulação do SNA. MÉTODOS:Um total de 42 fumantes foram divididos em dois grupos de acordo com o 50º percentil de atividade física de moderada a vigorosa (AFMV). A qualidade do sono foi avaliada utilizando-se o Mini-Sleep Questionnaire (mini questionário do sono), e a modulação do SNA foi avaliada por índices de variabilidade de frequência cardíaca (VFC). Para a análise de possíveis diferenças de média, foi utilizada a análise de covariância (ANCOVA) para ajuste de idade, gênero, composição corporal, maços-ano, betabloqueadores, ansiedade, e depressão, em log base 10, exceto por dados qualitativos, tais como gênero e betabloqueadores. Foram estabelecidas correlações utilizando-se a correlação de postos de Spearman. A significância estatística foi definida em 5%. RESULTADOS:Os fumantes que eram menos ativos demonstraram pior qualidade do sono (p=0,048) e insônia (p=0,045). Além disso, o grupo menos ativo apresentou redução na modulação parassimpática [HF (un; p=0,049); RMSSD (ms; p=0,047) e SD1 (ms; p=0,047)] e aumento do índice de LF (un) index (p=0,033) e razão LF/HF (p=0,040). Houve correlação positiva entre a pontuação total no Mini-sleep com o índice de LF (un) (r=0,317, p=0,041) e razão LF/HF (r=0,318, p=0,040) e correlação negativa com o índice de HF (un) (r= -0,322, p=0,038). CONCLUSÕES:Fumantes com baixo nível de atividade física habitual apresentaram baixa qualidade do sono e alterações na modulação do sistema nervoso autônomo.
