How the relationship between physical activity and health changes with age.

ABSTRACT: In the context of age-related declines in physical activity (PA) and the dramatic increase in ageing populations in many countries, this paper sheds further light on the link between PA and self-perceived health (SPH) by examining whether the magnitude of this relationship is age specific. With a sample of 14,456 Spanish individuals aged 18-69, we estimated three levels of intensity in PA using the International Physical Activity Questionnaire. Individuals who did more PA per week showed higher levels of SPH (??=?0.28; 95% CI 0.24-0.32), and age moderated this relationship, with a positive effect over age 49. People aged 50-59 and 60-69 who practiced PA had higher probabilities of better SPH compared with those aged 40-49 (??=?0.14; 95% CI 0.04-0.24) and (??=?0.32; 95% CI 0.21-0.43), respectively. This association between PA and SPH also depended on the intensity of PA, especially for walking (??=?0.14; 95% CI 0.04-0.24). In particular, in comparison with people age 40-49, a statistically significant relationship with SPH was found among people age 50-59 who walked (??=?0.22; 95% CI 0.07-0.36) and people age 60-69 who did moderate PA (??=?0.38; 95% CI 0.23-0.54). This paper provides a major rationale for the design, organisation and implementation of public policies promoting PA and healthy ageing for different age groups.

Project description:IntroductionThis study examines the dose-response relationship between moderate-to-vigorous physical activity and cardiometabolic measures in adolescents.MethodsCross-sectional spline analyses were performed using 2003-2016 National Health and Nutrition Examination Survey data among adolescents (aged 12-19 years, N=9,195) on objectively measured (2003-2006) and self-reported (2007-2016) weekly mean minutes of moderate-to-vigorous physical activity and cardiometabolic measures (systolic and diastolic blood pressure, total cholesterol, high-density lipoprotein, BMI, and cardiorespiratory fitness). Inflection points were determined for nonlinear relationships.ResultsFor objective moderate-to-vigorous physical activity, female adolescents had significant nonlinear associations with inflection points at 90 minutes/week for BMI percentile and systolic blood pressure. Male adolescents had inflection points at 150 weekly minutes of objective activity for BMI percentile and cardiorespiratory fitness. BMI percentile was about 7% lower for female and male adolescents at 150 weekly minutes of objectively measured moderate-to-vigorous physical activity than at 0 minutes. For self-reported moderate-to-vigorous physical activity, inflection points were at 375 minutes/week (diastolic blood pressure for female adolescents) and 500 minutes/week (systolic blood pressure for male adolescents).ConclusionsAmong several significant dose-response relationships between physical activity and cardiometabolic health in adolescents, consistent and often nonlinear relationships were identified for BMI, with inflection points at 90-150 minutes of objective moderate-to-vigorous physical activity. Notable differences in associations and linearity were identified by sex and physical activity measure (objective or self-reported). These results support calls for any increase in physical activity among adolescents and suggest that recommendations closer to the adult guidelines of 150 weekly minutes of physical activity may be health promoting and more attainable for youth than the current recommendation of 420 weekly minutes.

Project description:Background: A large body of evidence supports the positive effects of leisure time physical activity (LTPA) and exercise on cancer survivors. However, only a fraction of survivors manages to attain international PA recommendations. This can be attributed to several external and internal barriers toward PA those patients seem to encounter, with cancer related fatigue (CRF) being the most reported internal barrier. Nevertheless, self-efficacy and knowledge about the utilization of LTPA can serve as facilitators of PA, which also correspond to certain constituents of physical activity related health competence (PAHCO). Since PAHCO is not investigated in cancer survivors we investigated if PAHCO can mediate the negative relationship between CRF and LTPA. Methods: We surveyed 398 cancer survivors with different cancer types and therapy status. The patients completed the EORTC QLQ-FA12 (EORTC FA12) to assess CRF, the PAHCO questionnaire to assess PAHCO and the SQUASH to assess LTPA. We followed a two-step structural equation modeling approach. The first step established the measurement model, in the second step we fitted the mediation model. Since 163 patients chose not to answer the SQUASH, the mediation model was only fitted to the data of the remaining 235 participants. Results: The proposed measurement model of the PAHCO offered an excellent fit. We found small to moderate positive associations between the PAHCO dimensions and the LTPA, and negative moderate relationships between the PAHCO and the EORTC FA12 dimensions. We did not observe a relationship between the EORTC FA12 dimensions and the LTPA (p > 0.05). The hypothesized mediation models did not display an appropriate fit. Conclusion: The PAHCO confirmed its factorial validity; furthermore, it appears to have a positive relationship to LTPA. Therefore, integrating psycho-educational aspects can be beneficial in order to increase the PAHCO in exercise interventions. Because of the cross-sectional character of this study, causal conclusions are not suitable, therefore the longitudinal relationships of LTPA, CRF, and PAHCO require further investigation.
