AbstractObjectiveThe aim of the present study was to explore the existence of clusters in multiple lifestyle behaviours, including physical activity (PA), sedentariness and food habits, in young adolescents. The present study also investigated whether the identified groups could be characterised by gender and components of health-related physical fitness, especially weight status and cardiorespiratory fitness (CRF).DesignA cross-sectional survey. Leisure-time PA, sedentary behaviour and food consumption were assessed by a questionnaire. Overweight prevalence was estimated using BMI (kg/m2) calculated from self-reported height and weight. CRF was measured using a 20 m shuttle-run test.SettingThe study was conducted in four middle schools in Flanders, Belgium.SubjectsThe sample size was 317 seventh grade students aged 11–12 years.ResultsFour reliable and meaningful lifestyle clusters could be identified, labelled as ‘Sporty media-oriented mixed eaters’ (boys:n34; girls:n16), ‘Academic healthy eaters’ (boys:n30; girls:n58), ‘Inactive healthy eaters’ (boys:n38; girls:n57) and ‘Inactive media-oriented unhealthy eaters’ (boys:n35; girls:n49). The lifestyle clusters could not be characterised by adolescents’ weight status. Among boys, the ‘Sporty media-oriented mixed eaters’ group performed significantly better on the shuttle-run test than those in clusters with the lowest levels of PA (clusters 3 and 4).ConclusionsOur results showed that healthy and risk-related behaviours may coexist in some groups of young adolescents. Isolated unhealthy behaviours, such as high levels of screen-based media use or high consumption of energy-dense food items, are not necessarily related with negative health outcomes, on the condition that these risk-related behaviours co-occur with more health-enhancing behaviours such as PA.

It is not known whether children with Developmental Coordination Disorder (DCD) have lower cardiorespiratory fitness (CRF) than children without the disorder, or whether this relationship varies by age and gender. These issues are examined using a cross-sectional assessment of children 9-14 years of age (N = 549). Participants were screened for DCD using the short form Bruininks-Oseretsky Test of Motor Proficiency (BOTMP-SF). A BOTMP-SF age-adjusted standard score at or below the 10th percentile rank on the BOTMP-SF was required to classify a diagnosis for probable DCD. CRF was determined from each participant’s predicted peak-aerobic power using the Léger 20-m shuttle-run test. Children with DCD report lower CRF than children without the disorder and are more likely to be in a high-risk group (≤ 20th percentile in peak VO2). Moreover, 70% of boys with DCD scored at or below the 20th percentile in peak VO2. Further research in a laboratory setting should be conducted to confirm these findings.

Abstract Background Inhibitory control develops rapidly during the preschool stage, and development of inhibitory control in this period is significant for the healthy growth of the future. However, most studies paid more attention to children and adolescents in recent years, but less focus on preschool children. Therefore, the purpose of this study was to explore the association between the health-related physical fitness and inhibitory control in preschool children. Methods This study was a cross-sectional study, 128 preschool children in Yangpu District of Shanghai were recruited by convenient sampling. The health-related physical fitness T-score (HPFT) was obtained by adding standard scores of six indicators: body mass index, handgrip strength, standing long jump, one-leg balance, 2×10m shuttle run test, and 20m shuttle run test. Inhibitory control was assessed using the flanker task and reflected by reaction time and accuracy. Results A total of 120 preschoolers were included in the final statistical analysis. After adjusting the confounders, HPFT was associated with reaction time (β=-2.49ms, 95%CI: -4.22, -0.75). Similarly, a negative association was observed between one-leg balance and reaction time (β=-12.04ms, 95%CI: -18.94, -5.15), and between 20m shuttle run and reaction time (β=-23.28ms, 95%CI: -37.00, -9.56). Compared with the participants in the lowest tertile, HPFT (β=-158.74, 95%CI: -309.63, -7.84), one-leg balance(β=-267.25ms, 95%CI: -420.71, -113.79) and 20m shuttle run (β=-215.58ms, 95%CI: -374.67, -56.49) were all negatively associated with reaction time of those in the highest tertile. Conclusion In addition, there was a non-linear relationship between HPFT and reaction time (β=-3.46ms,95%CI: -5.39, -1.53) when HPFT > 249. In conclusion, in order to improve the inhibitory control, it’s suggested that HPFT of preschoolers should be at least 249.

Background:The main goal of this study was to analyze the associations between cardiorespiratory fitness (CRF) and body mass index (BMI) with self-rated health (SRH) of adolescent girls.Methods:This was a cross-sectional study of 533 adolescents girls, aged from 10 to 18 years old. CRF was predicted by maximal multistage 20-m shuttle-run test according to procedures described from FITNESSGRAM. Girls’ obesity status was classified according to International Obesity Task Force and Self-rated health (SRH) was assessed by questionnaire.Results:The findings showed that among adolescent girls 23.2% had negative SRH. Girls who were classified as unfit were more likely to report negative SRH in both univariate logistic (OR: 3.05; CI: 1.91−4.87; P < .05) and multivariate (OR: 2.93; CI: 1.82−4.72; P < .05) regression analyses compared with their fit peers. Obese girls were more likely to report negative SRH (OR: 2.30; CI: 1.14−4.62; P < .05) compared with their normal-weight counterparts. However such association was lost in multivariate analyses suggesting an effect of CRF.Conclusions:Negative perception of health was associated with lower CRF and weight status although such association it is mediated by CRF condition.

Abstract Background It is unclear whether active commuting has the potential to improve children’s health. This study examined the association of commuting mode and distance with children’s cardiorespiratory fitness (CRF). Methods We conducted a cross-sectional study, including 713 Slovenian schoolchildren aged 12 to 15 years. Commuting modes were self-reported, and four commuting groups were constructed, while CRF was determined with a 20-m shuttle run test. The distance from home to school was calculated using the Geographic Information System. Effects of commuting mode and distance, controlling for age, gender and amount of total physical activity, were evaluated using general two linear models (one for each direction of commuting to/from school). Results The main effect of commuting group on CRF and its interaction with distance were significant in the direction from school to home (P = 0.013 and P = 0.028, respectively), but not in the opposite direction. Predicted differences in CRF between commuting groups were moderate and generally higher in males than in females. When comparing commuting group median distance from home to school, males driven by car had around 4 ml/min/kg lower predicted CRF than those who walked (P = 0.01) or used wheels commuting (e.g., bicycle, skateboard). Conclusions The distance of commuting had a small effect on CRF, except in the Car group where children who live close to school had significantly lower CRF than those living further away. Children driven by car who live within wheels or walk distance from school should be targeted by interventions promoting active transport.

Abstract Working memory performance is associated with better academic achievements in children and adolescents, and it is positively related to CRF. However, what level of cardiorespiratory fitness (CRF) discriminates higher working memory performance is not known. The purpose of this study was to identify thresholds of CRF linked to working memory in adolescents. Data of 141 adolescents (53.2% girls) were collected (14.9 years) from a cross-sectional study during the year 2019. CRF was assessed by the 20-m shuttle run test, and maximal oxygen uptake were calculated by Mahar´s equation. Working memory was evaluated by the Corsi blocks test and the performance was classified by percentiles. Receiver operating characteristic (ROC) curve analysis was used to identify CRF thresholds. The results of ROC analysis indicated that CRF could be used to discriminate working memory in adolescents. CRF thresholds of ³45.03 ml.kg-1.min-1for boys and ³36.63 ml.kg-1.min-1for girls were found to be indicative of “normal” performance in working memory. ConclusionCRF could discriminate low and normal working memory performance in 14-16 years old adolescents. These thresholds could allow for earlier identification and intervention of low working memory performance by the CRF.

The purpose of the present study was to analyze if the association between sex with cardiorespiratory and muscular fitness is independent of physical activity, sports practice and sedentary behavior in young people. A cross-sectional study involving 729 participants aged 10 to 17 years. Physical activity, sports practice and sedentary behavior were assessed through a questionnaire. Cardiorespiratory fitness was measured using 20m shuttle run test and were analyzed: VO2max, number of laps and health-related criteria. Muscular fitness was assessed with 90o push-up test and number of repetition and health-related criteria was analyzed. Multiple linear regression was used to estimate β coeficients and Poisson regression estimated prevalence ratios (PR). Male sex was associated to higher cardiorespiratory fitness (VO2max β = 9.04 to 9.77, Laps PR=1.67 to 1.80, health-related criteria PR=2.03 to 2.09) and the same occurred with muscular fitness (repetitions PR=2.81 to 3.01, health-related criteria PR=1.91 to 2.09). Similarly, the stratification of the sample according to physical activity, sports practice and sedentary behavior did not change the associations between sex with cardiorespiratory (VO2max β=8.07 to 10.00, Laps PR=1.49 to 1.85, health-related criteria PR=1.64 to 2.27) and muscular fitness (repetitions PR=2.24 to 3.22, health-related criteria PR=1.76 to 2.06). These data suggest that higher cardiorespiratory and muscular fitness in males could not be attributed to physical activity, sports practice or sedentary behavior in young people.

Abstract Background Health Related Quality of Life (HRQL) is a multi-dimensional construct that can comprehensively evaluate the patient’s health status, including physical, emotional, mental and social well-being. In this study, we aimed to evaluate the impact of non-alcoholic fatty liver disease (NAFLD) on HRQL in a Chinese population. Methods In this national multicenter cross-sectional survey, patients with NAFLD were enrolled. Chronic Liver Disease Questionnaire (CLDQ)-NAFLD was used to qualify HRQL. Univariate and multivariate analysis were used to identify independent risk factors of HRQL. Results A total of 5181 patients with NAFLD from 90 centers were enrolled in this study (mean age, 43.8 ± 13.3 years; male, 65.8%). The overall CLDQ score was 5.66 ± 0.89. Multivariate logistic regression analysis showed that body mass index (BMI: HR, 1.642; 95% CI, 1.330–2.026), alanine transaminase (ALT: HR, 1.006; 95% CI, 1.001–1.011), triglyceride (HR, 1.184; 95% CI, 1.074–1.305), disease severity (HR, 3.203; 95% CI, 1.418–7.232) and cardiovascular disease (HR, 4.305; 95% CI, 2.074–8.939) were independent risk factors for overall CLDQ score. In the logistic analyses of individual domain, BMI and triglyceride were independent risk factors of all domains. ALT, disease severity, diabetes, depression and cardiovascular disease were influencing factors for the CLDQ score of several domains. Conclusions This national multicenter cross-sectional survey in China indicated that the HRQL in patients with NAFLD was impaired. HRQL was found to be significantly associated with sociodemographic and clinical factors. Attention should be paid to the optimally managing care of patients with NAFLD to improve their HRQL.
