Caraterização da atividade física e aptidão física de acordo com os níveis de solidão em adultos 50+

Abstract

Loneliness is a perception of dissatisfaction that seems to be the result of a lack of significant re-lationships, with multiple potential causal factors. The current body of research is not conclusive in relation to the link between loneliness and physical activity (PA) and physical fitness (PF) in adults and seniors. The aim of this cross-sectional study is to characterize PA and PF according to levels of loneliness (Social Isolation versus Affinities). The 62 Portuguese individuals (64.68 ± 6.85 years; 68% women) were assessed for loneliness (University of California Los Angeles 16-item Loneliness Scale - UCLA-16). and classified in Social Isolation or Affinities, i.e., presence of significant social rela-tionships. PA was estimated using a questionnaire (International PA Questionnaire - Short Version - IPAQ-SV ) and PF was evaluated using the Senior Fitness Test (upper and lower body strength, upper and lower body flexibility, cardiorespiratory fitness, agility and dynamic balance). Descriptive statistics were used. The comparison between groups was performed using parametric (t-test, AN-COVA adjusted to sex and chi-square) and non-parametric tests (Mann-Whitney). The prevalence of social isolation was 53%. The individuals of the Affinities group spent more minutes per day on moderate and vigorous physical activity (MVPA) than the individuals of the Social Isolation group (0.00 [0.00 ­ 12.86] versus 11.43 [0.00 ­ 17.14] minutes, respectively; p = 0.041). After adjusting for sex, the differences were no longer significant. Loneliness groups were not different in relation to PF. PA appears to contribute to a better mental profile in adults and seniors. The results should be confirmed through studies with larger samples
