    Effects of exercise in addition to a family-based lifestyle intervention program on hepatic fat in children with overweight

    OBJECTIVE Pediatric hepatic steatosis is highly prevalent and closely related to type 2 diabetes. This study aimed to determine whether the addition of supervised exercise to a family-based lifestyle and psycho-educational intervention results in greater reduction of percentage of hepatic fat (HF), adiposity, and cardiometabolic risk factors in children with overweight/obesity. RESEARCH DESIGN AND METHODS The study subjects of this nonrandomized, two-arm, parallel design clinical trial were 116 overweight/obese children (10.6 +/- 1.1 years of age, 53.4% girls) living in Vitoria-Gasteiz (Spain). For 22 weeks, they followed either a lifestyle and psycho-education program (control intervention [CInt], N = 57), consisting of two family-based education sessions/month, or the same plus supervised exercise (intensive intervention [II], N = 59) focused mainly on high-intensity aerobic workouts (3 sessions/week, 90 min/session). The primary outcome was the change in percentage of HF (as measured by MRI) between baseline and the end of the intervention period. Secondary outcomes included changes in BMI, fat mass index (FMI), abdominal fat (measured by DEXA), blood pressure, triglycerides, HDL, LDL, gamma-glutamyl transferase, glucose, and insulin concentrations. RESULTS A total of 102 children completed the trial (N = 53 and N = 49 in the CInt and II groups, respectively). Percentage of HF decreased only in the II group (-1.20 +/- 0.31% vs. 0.04 +/- 0.30%, II and CInt groups, respectively), regardless of baseline value and any change in adiposity (P < 0.01). BMI, FMI, abdominal fat (P <= 0.001), and insulin (P < 0.05) were reduced in both groups. CONCLUSIONS Multicomponent intervention programs that include exercise training may help to reduce adiposity, insulin resistance, and hepatic steatosis in overweight/obese children.

    Associations of dietary energy density with body composition and cardiometabolic risk in children with overweight and obesity: role of energy density calculations, under-reporting energy intake and physical activity
    (Cambridge University Press, 2019) Gómez Bruton, Alejandro; Arenaza Etxeberría, Lide; Medrano Echeverría, María; Mora González, José; Cadenas-Sánchez, Cristina; Migueles, Jairo H.; Muñoz-Hernández, Victoria; Merchán Ramírez, Elisa; Martínez Ávila, Wendy D.; Maldonado, José; Osés Recalde, Maddi; Tobalina, Ignacio; Gracia-Marco, Luis; Vicente Rodríguez, Germán; Ortega, Francisco B.; Labayen Goñi, Idoia; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    This study examined (1) the association of dietary energy density from solid (EDS) and solid plus liquids (EDSL) with adiposity and cardiometabolic risk factors (CRF) in children with overweight and obesity, (2) the effect of under-reporting on the mentioned associations and (3) whether the association between ED and body composition and CRF is influenced by levels of physical activity. In a cross-sectional design, 208 overweight and obese children (8-12-year-old; 111 boys) completed two non-consecutive 24 h recalls. ED was calculated using two different approaches: EDS and EDSL. Under-reporters were determined with the Goldberg method. Body composition, anthropometry and fasting blood sample measurements were performed. Moderate to vigorous physical activity (MVPA) was registered with accelerometers (7-d-register). Linear regressions were performed to evaluate the association of ED with the previously mentioned variables. Neither EDS nor EDSL were associated with body composition or CRF. However, when under-reporters were excluded, EDS was positively associated with BMI (P=0 019), body fat percentage (P=0 005), abdominal fat (P=0 008) and fat mass index (P=0 018), while EDSL was positively associated with body fat percentage (P=0 008) and fat mass index (P=0 026). When stratifying the group according to physical activity recommendations, the aforementioned associations were only maintained for non-compliers. Cluster analysis showed that the low-ED and high-MVPA group presented the healthiest profile for all adiposity and CRF. These findings could partly explain inconsistencies in literature, as we found that different ED calculations entail distinct results. Physical activity levels and excluding under-reporters greatly influence the associations between ED and adiposity in children with overweight and obesity.
