Higher levels of academic education are associated with higher levels of physical activity throughout the lifespan. However, the mechanisms underlying this association are unclear. Cognitive functioning is a potential mediator of this association because higher levels of education are associated with better cognitive function, which is related to greater engagement in physical activity. Here, we used large-scale longitudinal data from 105,939 adults 50 years of age or older (55% women) from the Survey of Health, Ageing, and Retirement in Europe to investigate whether initial status and change in cognitive function mediate the relationship between education and change in physical activity. Education and physical activity were self-reported. Cognitive function was assessed based on delayed recall and verbal fluency. Academic education was assessed at the first measurement occasion. The other measures were collected seven times between 2004 and 2019. The mediating role of cognitive function was tested using longitudinal mediation analyses combined with growth curve models. We found that higher levels of education were associated with higher levels and slower decreases in cognitive function, which in turn predicted a lower decrease in physical activity across time. These results support the presence of an indirect effect of education on physical activity trajectories by affecting the intercept and slope of cognitive function. Specifically, these findings suggest that both the initial status and change in cognitive function mediate the association between academic education and change in physical activity. In addition, results revealed that, across the aging process, differences in cognitive function and physical activity widen between the low and high educated. In other words, this study demonstrates the long-lasting effect of education on cognitive function and physical activity.

Lower economic status (ES) is associated with a less adaptive experience of school and physical activity. However, empirical evidence supporting the detrimental association of lower ES on the affective and motivational experience in Physical Education (PE) remains scarce. Using a large sample (n = 10392) of adolescents from six countries (i.e., Greece, Spain, Italy, Portugal, England, Turkey), this cross-sectional study tested whether students’ ES was associated with the satisfaction of their basic psychological needs in PE, and in turn with motivational and affective outcomes in PE and their out-of-school physical activity intention. We further explored whether gender moderated the abovementioned relationship. Multigroup structural equation modelling showed that, in five of six countries (i.e., Greece, Spain, Italy, Portugal, England), a lower ES was associated with lower basic needs satisfaction (β = .10, p < .001), which in turn was associated with lower enjoyment (β = .75, p < .001), lower autonomous motivation (β = .83, p < .001), and weaker out-of-school physical activity intention (β = .36, p < .001), higher displeasure (β = -.51, p < .001), higher controlled motivation (β = -19, p < .001) and stronger amotivation in PE (β = -.28, p < .001). Exploratory analyses suggested that the relationship between lower ES and the less adaptative outcomes was amplified among girls. At the crossroad between psychology and sociology, this study provides new insights into how family lower ES and gender might interact to predict less adaptative motivational and affective experiences and outcomes in PE.

Physical activity is unequally practiced across populations: relative to more privileged individuals, deprived people are less likely to be physically active. However, pathways underlying the association between deprivation and physical activity remain overlooked. Here, we examined whether the association between several indicators of deprivation (administrative area deprivation and self-reported individual material and social deprivation) and physical activity was mediated by body mass index (BMI). In addition, consistent with an intersectional perspective, we tested whether this mediating pathway was moderated by participants’ gender and we hypothesized that the mediating effect of BMI would be stronger among women, relative to men. We used two independent large-scale studies to test the proposed pathways cross-sectionally and prospectively. In a first sample composed of 5,723 British adults (Study 1), BMI partly mediated the cross-sectional association between administrative area deprivation and self-reported physical activity. Moreover, relative to men, the detrimental effect of deprivation on BMI was exacerbated among women, with BMI mediating 3.1% of the association between deprivation and physical activity among women (vs 1.5% among men). In a second sample composed of 8,358 European older adults (Study 2), our results confirmed the findings observed in Study 1: BMI partly mediated the prospective association between perceived material and social deprivation and self-reported physical activity. Moreover, compared to men, the effect of deprivation on BMI was more pronounced among women, with BMI respectively mediating 8.1% and 3.4% of the association between material and social deprivation and physical activity among women (vs 1.3% and 1.2% among men). These findings suggest that BMI partly explained the detrimental association between deprivation and physical activity, with this effect being stronger among women. Our study highlights the need to further consider how gender may shape the mechanisms behind the association between disadvantaged socio-economic circumstances and physical activity.
