“…Children's PA was measured by PDPAR and it is possible that obese children overestimated their daily physical activity. Although most studies have demonstrated that increasing RBMI is accompanied by decreasing DPA in children (17,(19)(20)(21)(22)(23), yet similar findings have been shown in the study of Manley et al (17). We suppose that such children like to do an overestimation of their DPA.…”

Background: There are a considerable number of published studies that strongly support the benefits of physical activity in children, and to achieve such benefits, guidelines recommend children to participate in at least 60 minutes of physical activity every day. There is a vicious cycle between low physical activity and increased body mass index. Objectives: The aim of this study was to assess daily physical activity and sedentary behavior in overweight and obese children. Patients and Methods:In this descriptive analytical study, 300 overweight and obese children were recruited to assess their daily physical activity, energy expenditure and screen times with standard techniques. Distribution of these variables was examined according to their demographic characteristics. Using Pearson's correlation test and linear regression the predictor effect between these variables was discovered. Results: There was a significant difference between physical activity and screen time according to Relative Body Mass Index (RBMI), gender and grade (P ≤ 0.001). Pearson's correlation test discovered a positive association between Weekly Screen Time (WST) and Daily Physical Activity (DPA) (r ≈ 0.37, P ≤ 0.001). In the regression model, children's screen time explained only about 13% of change in body mass index. Conclusions: Overweight and obese children may consume more energy according to the international recommendations. In parallel with this, they experience more sedentary behavior, as well. In this situation, planning to decrease their sedentary behavior is at greater priority.

“…Body composition changes with physical activity. Physicians and health workers have claimed that their obese and overweight clients perform more physical activity (4,6,29). In our research the contradictory results may be due to application of the self-report tool (PDPAR) for physical activity assessment.…”

“…In our research the contradictory results may be due to application of the self-report tool (PDPAR) for physical activity assessment. All of the self-report tools have a common disadvantage, which is probability response bias (4,30). This refers to the subjects' tendency to respond a certain way, regardless of the actual evidence.…”

“…It affects approximately 10 percent of children worldwide and seems to be more common in developing countries, and there are some influential variables, such as daily activities, diet, psychosocial factors, ethnicity, parental views, gender, socioeconomic status and genetics (4)(5)(6)(7)(8)(9)(10). As the prevalence of being overweight and obesity in children is associated with health risk consequences in adulthood, most health interventions have aimed to manage children's weight via change in their diet habits, daily activity and scheduling screen time (11)(12)(13)(14).…”

Background: One of the most important threats for children's health status is being overweight and obesity, and related causes such as screen time prevalence. Prevalence of being overweight and obesity in children is associated with health risk consequences in adulthood. Objectives: The purpose of this study was to assess the prevalence of screen time and physical activity in overweight and obese students. Patients and Methods: In this cross sectional descriptive study we randomly selected 302 students, from all districts of Qazvin, who's relative body mass index (RBMIs) were above the 85th percentile. Their screen time and physical activity prevalence were assessed with two separate techniques (self-report and parent-report). Pearson correlation test and regression analysis were done to examine the association between RBMI, screen time and physical activity. Results: Mean screen time in boys was more than girls, in both overweight screen time-self report technique (ST-SRT: 1.93 ± 0.24 vs. 1.26 ± 0.44, ST-PRT: 3.4 ± 0.22 vs. 2.1 ± 0.15) and obese subjects (ST-SRT: 1.88 ± 0.31 vs. 1.37 ± 0.49, ST-PRT: 3.2 ± 0.32 vs. 2.3 ± 0.34) yet overweight subjects had less total screen time than obese individuals (P < 0.05). Pearson correlations with one-tailed test indicated that screen time had a significant association with RBMI. In addition, there was a significant association between the two techniques of screen time and physical activity measurements. The model of regression for screen time and RBMI was significant (F = 45, P = 0.000, R 2 = 0.42) and screen time explained about 16% of variance in RBMI (B = 0.021, SEB = 0.004, β = 0.325). Conclusions: Our research determined an association between screen time, physical activity and RBMI. Screen time was a prominent predictor of RBMI in children. It is important for health workers to decrease screen time of children to prevent the prevalence of being overweight and obesity.

“…Adicionalmente, Manley et al, 16 verificaram que uma intervenção utilizando pedômetros em adolescentes de 11 a 13 anos, foi eficaz para a melhora da aptidão aeróbica e nível de atividade física. Entretanto, apesar de ser evidenciado na literatura a eficácia do pedômetro sobre a prática de atividade física de crianças e adolescentes, ainda não está claro se uma intervenção com pedômetro de um período relativamente curto seria eficaz na modulação do perfil metabólico de crianças obesas.…”

RESUMO Introdução: Nas últimas décadas, a incidência de obesidade na população pediátrica vem aumentando, juntamente com a inatividade física. A obesidade e a inatividade física são componentes predisponentes para o agravo dos fatores de risco metabólico, sendo de fundamental importância seu tratamento visando melhora da saúde dos jovens. Objetivo: Verificar o efeito de 12 semanas de uma intervenção focada na atividade física sobre os fatores de risco metabólico em crianças obesas. Métodos: A amostra final foi composta por 19 escolares com idade entre oito e 10 anos (10 no grupo pedômetro e nove no grupo controle). A atividade física foi mensurada e orientada por meio do pedômetro Yamax(r) sw 700 (Tóquio, Honchu, Japão). Para comparações intra e entre grupos foi aplicado a ANOVA two way para medidas repetidas com significância estipulada em p < 0,05. Resultados: O número de passos aumentou significativamente somente no grupo pedômetro após as 12 semanas de intervenção (pré 9729,7 ± 2539,8 vs. pós 13151,6 ± 3581,7). Foi observado aumento significativo do peso corporal, da estatura e do IMC no grupo controle. No grupo pedômetro, observou-se aumento significativo apenas na estatura. Com relação aos fatores de risco metabólicos, não foi encontrada mudança significativa no grupo controle, enquanto no grupo pedômetro foi observada diminuição significante nos valores de insulina (pré 12,21 ± 8,53 vs. pós 7,26 ± 4,70 µUI/ml) e HOMA IR (pré 2,76 ± 1,93 vs. pós 1,49 ± 0,93). Conclusão: A presente intervenção com atividade física a partir do estabelecimento de metas utilizando pedômetros reduziu significativamente as concentrações de insulina e o índice de homeostase (HOMA IR) em crianças obesas, independentemente da perda de peso.
