This study examined the association between access to electronic devices in the home and cardiorespiratory fitness in children. Participants were children aged 8–12 years from a local elementary school (n = 106, mean age = 9.7 + 1.1 years, male = 50). Child access to electronic devices was measured with a 37-item parent-reported questionnaire. Estimated maximal aerobic capacity (VO2 Peak) was calculated from The Progressive Aerobic Cardiovascular Endurance Run (PACER) using a validated algorithm. The association between access to electronic devices in the home and cardiorespiratory fitness was explored by employing hierarchical ridge regression, using the Ordinary Least Squares (OLS) model, controlling for the covariates of sex, age, and Body Mass Index (BMI). Controlling for sex, age, and BMI, the number of electronic items in a child’s bedroom was significantly inversely related to the estimated VO2 Peak (b = −1.30 mL/kg/min, 95% C.I.: −2.46 mL/kg/min, −0.15 mL/kg/min, p = 0.028) and PACER laps (b = −3.70 laps, 95% C.I.: −6.97 laps, −0.41 laps, p = 0.028) However, the total number of electronic items in the home and total number of electronic items owned did not significantly relate to the estimated VO2 Peak (p = 0.847, 0.964) or the number of PACER laps (p = 0.847, 0.964). Child health behavior interventions focused on the home environment should devote specific attention to the bedroom as a primary locus of easily modifiable intervention.

Health Behavior Interventions

This chapter suggests that an integration of perspectives from personality and social psychology (i.e., a Person × Intervention strategy framework) provides a rich context to explore precise specifications of the mediators and moderators that guide health behavior and decision-making. First discussed is how conceptualizations of moderated mediation and mediated moderation can enrich theory and serve to enumerate specific principles to guide the development and dissemination of more effective health behavior interventions. Second, research is reviewed from four different literatures that rely on a similar Person × Intervention strategy framework (i.e., the effectiveness of an intervention strategy depends on the degree to which it matches features of the target person) to examine evidence for the processes that mediate the effect of this moderated intervention approach. Finally described is how a more systematic analysis of the interplay between mediating and moderating processes can stimulate advances in theory, intervention research, and practice of health behavior.

There is conflicting evidence regarding the association between metabolically healthy obese (MHO) and metabolically unhealthy normal weight (MUNW) with incident hypertension and type 2 diabetes. The role of cardiorespiratory fitness on these associations has not been fully explored. We tested the hypothesis that obesity phenotypes predict incident hypertension and type 2 diabetes, but cardiorespiratory fitness modifies these associations in a prospective study of apparently healthy men. 3800 men (mean age 48±6 yrs, range 20-76 yrs) participated in two health examinations during 1998-2009. All subjects were free of hypertension and type 2 diabetes at baseline examination. MHO was defined as obesity (body mass index ≥ 25 kg/m2) with no more than one metabolic abnormality, and MUNW was defined as body mass index < 23 kg/m2) with two or more abnormalities. Cardiorespiratory fitness was directly measured by peak oxygen uptake during a treadmill test. Incident hypertension and type 2 diabetes were defined as blood pressure ≥140/90mmHg and as ≥6.5% of HbA1c or ≥126mg/dl of fasting glucose at second examination, respectively. During an average follow-up of 5 years (1-12 yrs), there were 371 (9.8%) men incident hypertension and 170 (4.5%) men incident type 2 diabetes. MHO and MUNW were present in 844 (22%) and 249 (6.6%) men. Compared with metabolically healthy normal weight men, MHO and MUNW men were at increased risk for hypertension (relative risk (RR) =1.82, 95% Confidence Interval (CI): 1.29-2.56 and 1.75, 1.11-2.74) and type 2 diabetes (RR=3.68, 1.92-7.07 and 5.35, 2.61-10.94), respectively. These risks in MHO and MUNW men were still persisted with adjustment for confounder variables and cardiorespiratory fitness (hypertension=1.57, 1.05-2.34 and 1.59, 1.01-2.51; type 2 diabetes=3.35, 1.63-6.89 and 4.76, 2.32-9.77). Metabolically healthy obese or metabolically unhealthy normal weight men were at increased risk of hypertension and type 2 diabetes compared with metabolically healthy normal weight men. However, these associations were not attenuated by cardiorespiratory fitness or other confounder factors.

We investigated if cardiorespiratory fitness modifies the association between obesity and the level of physical activity. In this cross-sectional study, we analyzed data from 746 adults, free of diagnosed cardiorespiratory or locomotor diseases. We analyzed sociodemographic and clinical information, cardiovascular risk factors, cardiorespiratory fitness, anthropometry, and level of physical activity (time spent in moderate-to-vigorous physical activity). Those that spent more time in moderate-to-vigorous physical activity were younger, male, with lower body mass index, without self-reported arterial blood hypertension, diabetes and dyslipidemia, non-smokers, and presented with better cardiorespiratory fitness. The linear regression coefficients showed that cardiorespiratory fitness changes according to the level of physical activity and body mass index (obesity in low cardiorespiratory fitness: β 6.0, p = 0.213, 95%CI -3.5 to 15.6; in intermediate cardiorespiratory fitness: β 6.3, p = 0.114, 95%CI -1.5 to 14.2; in high cardiorespiratory fitness: β -6.3, p = 0.304, 95%CI -18.4 to 5.8). This effect modification trend was present after adjusting the model by covariates. Cardiorespiratory fitness potentially modifies the association between body mass index and the level of physical activity. It should be routinely assessed to identify persons with overweight/ obesity with low/ intermediate cardiorespiratory fitness to prescribe individualized training.

Abstract Today’s children are born into a digital world and are exposed to various electronic devices and digital contents both in the home environment and other environments since the first years of life. Children, who are a natural recipient of the environment in which they live, are exposed to the effects of the digital world at different levels and reflect these effects in different ways. The purpose of the reported study is to investigate if preschoolers’ daily media usage habits affects their drawings. This study is planned according to the case study design of qualitative research methods. The study was conducted with 15 preschoolers and their parents. There were nine boys and six girls in the study. The preschoolers’ drawings and their parents’ interview data were analyzed by using the descriptive analyzing method. The study result shows that there are differences between boys and girls media usage habits. Boys spend more time with media tools than girls. Additionally, boys are exposed to more inappropriate content because of their preferences. The analysis of their drawings revealed that boys are more affected than girls from media contents since boys’ drawings include more characters from media than girls. It can thus be suggested that media tools might be harmful when they are used in a developmentally inappropriate way, and excessive media tool usage has negative impact on children. Therefore, the reported study recommends that parents and caregivers take some precautions to limit preschoolers from spending time with media tools and to control content of children’s activity.
