Nível de atividade física combinado ao comportamento sedentário e excesso de peso em idosos: efeitos paradoxais em associação com a qualidade do sono

Abstract

The present study aimed to analyze the relationship between sleep quality and nutritional status and physical activity combined with sedentary behavior in elderly residents of the city of Alcobaça, State of Bahia. It was characterized as observational, of the analytical type with cross-sectional design. The population of this study comprised 473 people of both sexes, aged ≥ 60 years, living in the city of AlcobaçaBA. The data were collected through anthropometric measures of weight (kg) and height (m) to obtain the body mass index (BMI = Kg / m²) and the use of a questionnaire applied in the form of an individual interview, containing sociodemographic, physical and mental health, functional capacity, habitual physical activity and exposure to sedentary behavior. The level of physical activity was assessed through the International Physical Activity Questionnaire (IPAQ), in the long version adapted for the elderly, and the exposure to sedentary behavior was evaluated considering the total time spent sitting during one day in the week and one day in the through the IPAQ sitting time domain. Sleep quality was assessed using the Pittsburgh scale (PSQI). For data analysis, descriptive statistics (mean and standard deviation) and inferential procedures (Chi-square and Poisson logistic regression models) were used p≤0.05. The prevalence of poor sleep quality was 37.6%, 29.4% for men and 70.6% for women. Poor sleep quality was associated with respiratory problems, did not feel energy to perform activities and BMI> 30 kg / m² (obese elderly) (p≤0.05). There was the construction of a theoretical model that leaves explicit the relations of deprivation and excess of sleep besides the high exposure to the sedentary behavior and with the obesity. The findings of this research provide information that contributes to the formulation of more effective intervention strategies that aim at maintaining the body weight of the elderly and other factors associated with improved sleep quality.
