“…On the other hand, video game addiction is related to decreased levels of physical activity, since it is important to note that the pathological use of videogames in school children is closely related to physical inactivity [44,56,57], although active videogames, given their high motivating potential, complement levels of physical-sporting activity, allowing adherence to healthy lifestyles [58][59][60][61][62].…”

The creation of healthy habits and lifestyles is fundamental in the educational field and for acquiring adequate health levels that will prevail in adulthood. The aim of this study was to determine the characteristics and correlations between the level of practice of physical activity, adherence to the Mediterranean diet (MD), body mass index (BMI) and problematic use of videogames and self-concept of primary education students. This non-experimental, cross-sectional study is composed of a sample of 577 students aged 10-12 years (11.1 ± 0.638). Subjects were evaluated using the Mediterranean Diet Adherence questionnaire (KIDMED), Self-Concept Form-5 (AF-5), Experiences Related to Videogames (QERV) and anthropometric measurements were taken following the guidelines of the International Society for the Advancement of Kinanthropometry. Most students have been found to be of normal weight, although one in five has problems with being overweight or experiencing obesity. Likewise, half of them need to improve their adherence to the Mediterranean diet, while they do not have a problematic use of videogames, although one tenth of them in these early ages offer severe problems and it is highlighted that students offer an adequate self-concept. It is also noted that BMI correlates positively with problematic videogame use and social self-concept. Greater addiction to videogames is associated with poorer academic performance, low levels of physical activity and poor adherence to the Mediterranean diet. Finally, it should be noted that the continued practice of physical-sports activity favors emotional competence and academic performance.

“…The level of agreement between these two measurements indicates that accelerometer is measuring what self-report is measuring, and the error observed may be due to over-and under-reporting of the actual MVPA. Other validation studies reported similar findings, which reflects the limitations of children's accuracy to report their actual minutes of MVPA 8,18,19 .…”

Background: Self-reports are commonly used to assess physical activity in children. Existing self-reports for physical activity have not been validated for use among primary school children in Kilimanjaro, Tanzania. In order to understand if primary school children can accurately report their physical activity, we examined the validity of self-reported physical activity against accelerometer measured physical activity. Methods: A community based cross-sectional study was conducted from May to July, 2018 among four primary schools in Moshi municipal and Moshi rural districts, Kilimanjaro, Tanzania. A total of 51 primary school children aged 9–11 years were enrolled using a simple random sampling technique. A self-reported questionnaire was used to collect physical activity related variables. In addition, children wore accelerometers for seven consecutive days to capture physical activity movements. Spearman’s rank test and Bland Altman plots were used for assessing validity and agreement between self-reports and accelerometer moderate to vigorous physical activity (MVPA). Results: The mean age of the study participants was 10 (SD=0.8) years. Majority of the study participants were female 32 (63%). A moderate, positive correlation was found between self-reports and accelerometer MVPA (rho=0.36, p=0.009). Accelerometer had higher MVPA compared to self-reports. Children who reported walking to school had higher MVPA for both accelerometer and self- reports compared to children who use other means of transport to school, e.g. school buses (p < 0.001). Conclusions: This study found the moderate positive correlation between self-reports and accelerometers. Self-reports are prone to errors due to recall bias, and this interferes their validity. More research is needed to develop better self-reported measures with specific activities which can easily be recalled by children. Also, researchers have to be aware of self-reports validity limitation.

“…The Bland Altman plots shows a similar trend of randomness, indicating that accelerometer is measuring what self-report is measuring, and the error observed may be due to over-and under-reporting of the actual MVPA. This reflects the limitations of children's accuracy to report their actual minutes of MVPA as described in other studies (8,17,18).…”

Background: Insufficient physical activity is a serious public health concern. Assessing physical activity accurately in children remains a challenge and valid tools for its assessment in African children are needed. This study compares self-reports versus accelerometry-captured physical activity.Methods: In this cross-sectional study, 51 primary school children aged 9 – 11 years from four primary schools in Kilimanjaro region were enrolled. Children were asked to complete a self-reported questionnaire on physical activity and wore an accelerometer for seven consecutive days. Accelerometry was used as a reference method to assess for child reporting accuracy.Results: Spearman correlation between self-reports and accelerometry was moderate (r=0.41, p=0.002). Children who reported walking to school had higher moderate to vigorous physical activity (MVPA) for both accelerometry and self- reports compared to their counterparts (p < 0.001). Intra-class correlation (ICC) showed that 32% of the variations in accelerometry weekly total MVPA was contributed by the differences in activities between children.Conclusions: Objective measures of physical activity such as accelerometers can be used to accurately measure physical activity in children where feasible. Self-reports have limited validity, and therefore more research is needed to develop better self-reported measures with specific activities which can easily be recalled by children.
