Between the four questionnaires, the weekly volume of MVPA statistically significant differed (SIM: MED = 90.0 (MIN = 0.0, MAX = 210.0), DEGS: MED = 120.0 (MIN = 0.0, MAX = 420.0), EHIS: MED = 24.0 (MIN = 0.0, MAX = 1395.0), EURO: MED = 51.0 (MIN = 0.0, MAX = 2430.0), p < .001, all pairwise comparisons p < .01), as well as the prevalence of participants achieving the MVPA recommendations (SIM 31.3% (95% CI 24.5–38.7), DEGS 43.2% (95% CI 35.8–50.8), EHIS 67.0% (95% CI 59.6–73.9), EURO 87.5% (95% CI 81.7–92.0), p < .001), except between SIM and DEGS (p = .067).

For example, the study by Steene-Johannessen et al. [26] also used questionnaires that were employed in large surveys yet found substantial discrepancies in the prevalence estimates [26].

Moreover, regarding the classification of persons in terms of achieving the MVPA recommendations, self-reports show low or moderate sensitivity compared to objective measurement methods and low levels of agreement [26, 42, 62]. Consequently, the potential and utility of integrating device-based measures into PA surveillance or a combination of objective and subjective measurement methods should be considered to validly and reliably survey the (WHO’s) whole PA recommendations [26, 38, 43, 63, 64] .

For this purpose, we used instruments that were frequently used in population-based surveys as well as the SMI, which can very simply survey the achievement of PA recommendations.
