Associations between physical activity and quality of life outcomes in adults with severe obesity: a cross-sectional study prior to the beginning of a lifestyle intervention

Abstract

BackgroundSeverely obese individuals who seek lifestyle interventions have impaired quality of life (QoL). Research suggests that physical activity (PA) plays a role in weight reduction and improved health in this group, but knowledge about the association of PA with QoL outcomes is sparse and inconsistent. The aim of this study was to investigate whether a higher level of PA was independently associated with higher QoL in severely obese individuals prior to the beginning of a lifestyle intervention.MethodsDuring 2010, a total of 49 severely obese individuals who began a lifestyle intervention programme in Western Norway agreed to participate in the study. Data were collected prior to the beginning of the intervention. QoL was measured by a one-item scale on life satisfaction and the SF-36, PA was measured by an accelerometer, and clinical data were collected by health staff. Linear regression analyses were used to determine the associations between PA and QoL outcomes (life satisfaction, physical functioning, and mental health), adjusting for age, gender, and body mass index (BMI).ResultsIn the adjusted analyses, we found positive relationships between PA and life satisfaction (Stand. coeff. 0.39, p = 0.024) and physical functioning (Stand. coeff. 0.34, p = 0.025). There was no association between PA and mental health (Stand. coeff. 0.15, p = 0.376).ConclusionThis study detected associations between objectively measured PA and life satisfaction as well as physical functioning in a group of severely obese individuals before they began a lifestyle intervention programme.

Diet and physical activity in people with intermediate cardiovascular risk and their relationship with the health-related quality of life: results from the MARK study

“…This improves the overall quality of life [20, 21]. Similar results were found in special populations such as the elderly or the obese [22, 23]. …”

“…Similarly, the comprehensive review of Vagetti et al [44] indicated a positive association between physical activity and quality of life in the elderly that was consistently associated with functional ability and vitality, among other domains. A cross-sectional study of adults with obesity conducted by Jepsen et al [23] prior to a lifestyle intervention showed a significant association with general health. In contrast, a randomized controlled clinical trial of inactive persons [16] with a program to promote physical activity as an intervention, found no statistically significant changes between the experimental and control group in regard to the quality of life related to health.…”

Efectos de la suplementación de omega-3 y entrenamiento de intervalos de alta intensidad en el rendimiento físico, presión arterial y composición corporal en individuos sedentarios con sobrepeso

“…La obesidad y el sobrepeso son considerados hoy en día enfermedades crónicas de origen multifactorial prevenibles, caracterizadas por una acumulación excesiva de grasa o hipertrofia general del tejido adiposo en el cuerpo (1). Una elevada cantidad de adiposidad central y visceral se encuentra asociada a elevado riesgo cardiovascular, aumentando la síntesis de colesterol, glucosa e insulina, generando alteraciones metabólicas (2).…”

“…(17) encontraron un aumento de precursores de la biogénesis mitocondrial (PGC-1α) 24 y 48 horas después de la administración de O3 a células de rabdomiosarcoma humano. Estos resultados sugieren que los aumentos de VO 2max reportados posterior a suplementación de O3 se deberían al incremento en precursores de la biogéne-sis mitocondrial y aumentando la capacidad oxidativa total del músculo esquelético (1). Sin embargo, la combinación de HIIT y suplementación de O3 no han sido investigados; es posible que la combinación de estas dos intervenciones combinadas produzca mejores adaptaciones metabólicas que cada una por separado.…”

Peer Review #1 of "Factors and associations for physical activity in severely obese adults during a two-year lifestyle intervention (v0.1)"

“…In combination with diet modification, physical activity (PA) constitutes a core component of many lifestyle interventions for severely obese adults (Kirk et al, 2012;Dalle Grave, Calugi & El Ghoch, 2013). Studies have shown that PA impacts on weight loss and its maintenance (Catenacci & Wyatt, 2007;Butryn, Webb & Wadden, 2011), improves body composition (Lee et al, 2005;Kay & Fiatarone Singh, 2006;Goodpaster et al, 2010), reduces risk of cardio-metabolic comorbidities (Fogelholm, 2010;Goodpaster et al, 2010), and is positively associated with quality of life (Bond et al, 2006;Lerdal et al, 2011;Jepsen et al, 2013) in severely obese subjects. Thus, given the chronic nature of severe obesity, adherence to PA is important (Tsigos et al, 2008), but unfortunately PA decreases with increasing body mass index (BMI) (Tudor-Locke PeerJ reviewing PDF | (v2014:05:2118:1:1:NEW 1 Jul 2014) et al, 2010;Hansen et al, 2013).…”
