Background: Home confinement during the COVID-19 pandemic could have affected lifestyle behaviours of children, however evidence about it is emerging and yet scarce. Objectives: To examine the effects of the COVID-19 confinement on lifestyle behaviours in Spanish children, and to assess the influence of social vulnerabilities on changes in lifestyle behaviours. Methods: Physical activity (PA), screen time, sleep time, adherence to the Mediterranean diet (KIDMED) and sociodemographic information were longitudinally assessed before (N = 291, 12.1 ± 2.4 years, 47.8% girls) and during the COVID-19 confinement (N = 113, 12.0 ± 2.6 years, 48.7% girls) by online questionnaires. Results: During the COVID-19 confinement, PA (−91 ± 55 min/d, P <.001) and screen time (±2.6 h/d, P <.001) worsened, whereas the KIDMED score improved (0.5 ± 2.2 points, P <.02). The decrease of PA was higher in children with mother of non-Spanish origin (−1.8 ± 0.2 vs −1.5 ± 0.1 h/d, P <.04) or with non-university studies (−1.7 ± 0.1 vs −1.3 ± 0.1 h/d, P <.005) in comparison to their counterparts. Conclusion: This study evidence the negative impact of the COVID-19 confinement on PA levels and sedentary behaviours of Spanish children. These findings should be taken into account to design and implement public health strategies for preserving children´s health during and after the pandemic, particularly, in children with social vulnerabilities.

Association of breakfast quality and energy density with cardiometabolic risk factors in overweight/obese children: role of physical activity
(MDPI, 2018) Arenaza Etxeberría, Lide; Muñoz-Hernández, Victoria; Medrano Echeverría, María; Osés Recalde, Maddi; Amasene, María; Merchán Ramírez, Elisa; Cadenas-Sánchez, Cristina; Ortega, Francisco B.; Ruiz, Jonatan R.; Labayen Goñi, Idoia; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
There is a general belief that having breakfast is an important healthy lifestyle factor; however, there is scarce evidence on the influence of breakfast quality and energy density on cardiometabolic risk in children, as well as on the role of physical activity in this association. The aims of this paper were (i) to examine the associations of breakfast quality and energy density from both solids and beverages with cardiometabolic risk factors, and (ii) to explore whether physical activity levels may attenuate these relationships in children with overweight/obesity from two projects carried out in the north and south of Spain. Breakfast consumption, breakfast quality index (BQI) score, BEDs/BEDb (24 h-recalls and the KIDMED questionnaire), and physical activity (PA; accelerometry) were assessed, in 203 children aged 8-12 years who were overweight or obese. We measured body composition (Dual X-ray Absorptiometry), uric acid, blood pressure, lipid profile, gamma-glutamyl-transferase (GGT), glucose, and insulin, and calculated the HOMA and metabolic syndrome z-score. The BQI score was inversely associated with serum uric acid independently of a set of relevant confounders (= -0.172, p = 0.028), but the relationship was attenuated after further controlling for total PA (p < 0.07). BEDs was positively associated with total and HDL cholesterol, and systolic blood pressure regardless of confounders (all p < 0.05), while BEDb was positively associated with HOMA in either active/inactive children (all p < 0.03). In conclusion, higher breakfast quality and lower breakfast energy density should be promoted in overweight/obesity children to improve their cardiometabolic health.

Differences in areal bone mineral density between metabolically healthy and unhealthy overweight/obese children: the role of physical activity and cardiorespiratory fitness
(Springer Nature, 2019) Ubago Guisado, Esther; Gracia-Marco, Luis; Medrano Echeverría, María; Cadenas-Sánchez, Cristina; Arenaza Etxeberría, Lide; Migueles, Jairo H.; Mora González, José; Tobalina, Ignacio; Escolano Margarit, María Victoria; Osés Recalde, Maddi; Martín Matillas, Miguel; Labayen Goñi, Idoia; Ortega, Francisco B.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
Objectives: To examine whether areal bone mineral density (aBMD) differs between metabolically healthy (MHO) and unhealthy (MUO) overweight/obese children and to examine the role of moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness (CRF) in this association. Methods: A cross-sectional study was developed in 188 overweight/obese children (10.4 ± 1.2 years) from the ActiveBrains and EFIGRO studies. Participants were classified as MHO or MUO based on Jolliffe and Janssen’s metabolic syndrome cut-off points for triglycerides, glucose, high-density cholesterol and blood pressure. MVPA and CRF were assessed by accelerometry and the 20-m shuttle run test, respectively. Body composition was measured by dual-energy X-ray absorptiometry. Results: In model 1 (adjusted for sex, years from peak high velocity, stature and lean mass), MHO children had significantly higher aBMD in total body less head (Cohen’s d effect size, ES = 0.34), trunk (ES = 0.43) and pelvis (ES = 0.33) than MUO children. These differences were attenuated once MVPA was added to model 1 (model 2), and most of them disappeared once CRF was added to the model 1 (model 3). Conclusions: This novel research shows that MHO children have greater aBMD than their MUO peers. Furthermore, both MVPA and more importantly CRF seem to partially explain these findings.
