    Abstract: This study aims to analyze the associations between whole-body reaction-movement time (RT) and anaerobic power performance among Saudi athletes participating in different sports. Fifty athletes (age 18-26 years) of four different sport groups representing sprinters (SP, n=12), fencers (FN, n=13), table tennis player (TT, n=12) long-distance runner (LD, n=13), and one non-athlete group (NA, n=8) participated in the study. All groups performed Wingate Anaerobic Test (WAnT), and the vertical jump (VJ) test. RT was recorded using a sound (RT-S), light (RT-L), and a choice of light (RT-C). There were no significant differences in reaction-movement time between LD, SP, FN, TT, or NA groups. However, tests between subjects showed significant differences relative to sport type in muscular power (p=0.011), absolute maximal anaerobic power (p=0.008), absolute average anaerobic power in 30 seconds (p=0.001), average anaerobic power relative to body weight (p=0.007), and in fatigue index (p=0.028). Fencers recorded the highest values in absolute anaerobic power, absolute average power in 30 seconds, and average anaerobic power relative to body mass. Sprinters showed the highest decrement in anaerobic power during the 30-second test (18.7±6.0 watts/sec). Partial correlation coefficients (r) of selected anthropometric variables with reaction time and anaerobic power were calculated. This study showed that there were no significant changes in reaction-movement time between LD, SP, FN, TT, or NA groups. However, tests between subjects showed significant differences relative to sport type in muscular power, absolute maximal anaerobic power, absolute average anaerobic power in 30 seconds, average anaerobic power relative to body weight, and fatigue index.

    Abstract: To compare three body mass index (BMI) classifications that are used to assess the prevalence of overweight and obesity among Saudi children aged 6–13 years: the International Obesity Task Force (IOTF) age and gender cutoffs, the World Health Organization (WHO) growth references for school-aged children, and the Saudi (KSA) national growth references. Methods The sample comprised 2,169 children (52.5% girls) derived from two cross-sectional studies conducted in Riyadh and Jeddah during the 2017 and 2019 school years, respectively. Body weight and height were measured, and BMI was calculated. Results The proportions (%) of the participants who were classified as underweight, overweight, and obese varied according to the reference used: IOTF reference (13.8, 18.4, and 12.7), WHO reference (17.2, 19.1, and 18.9), and KSA reference (7.0, 22.4, and 9.3), respectively, indicating higher values for overweight and obesity prevalence when the WHO references were used. Kappa agreement measures between the three references were found to be high, with the coefficients ranging from 0.936 (between the IOTF and KSA references) to 0.849 (between the IOTF and WHO references). In all three classifications, girls exhibited lower overweight or obesity prevalence than boys. Family income, but not paternal or maternal education, was significantly ( p = 0.015) associated with overweight/obesity when using the IOTF standards. In addition, having a small family in the house was significantly ( p & lt; 0.05) associated with obesity, irrespective of the classification system. Conclusion Inconsistency was observed when estimating the prevalence of underweight, overweight, and obesity among Saudi children. However, when defining the overall prevalence of overweight plus obesity among Saudi children, the IOTF classification system performed in a similar way to the KSA references (31.1% versus 31.7%) compared to the WHO references (38.0%).

    Abstract: Breakfast is an important meal that provides essential nutrients and energy. However, few comprehensive studies have reported breakfast habits and related behaviors among Saudi children. This study investigated breakfast consumption patterns and the associations of socio-demographic variables with daily breakfast intake among Saudi children. Methods A multistage stratified cluster random sampling technique was used to select 1051 elementary school boys and girls in Riyadh. Body weight and height were measured and body mass index (BMI) was computed. The breakfast eating habits and behaviors were assessed using a specifically designed self-reported questionnaire that was completed by the children’s parents. Results More than 79% of children skipped daily breakfast, with no significant sex difference. Children in private schools consumed breakfast more frequently than those attending public schools. Multivariate analyses showed that boys in private schools had a significantly higher intake of breakfast than that in boys in public schools, yet, boys in public schools had significantly higher BMI than boys in private schools. Using logistic regression while adjusting for confounders showed insignificant effect for parent education. Among breakfast eaters, spread cheese sandwiches were consumed most frequently, followed by fried egg sandwiches and breakfast cereals. Full-fat milk, tea with milk, water, and fruit juice were the most consumed drinks. Girls consumed significantly more fresh fruits during breakfast than did boys. Mothers prepared breakfast at home most of the time (84.5%). Parents appeared mostly satisfied with the breakfast consumed by their child at home and placed high importance on breakfast compared to lunch or dinner. Conclusions The proportion of school children who ate daily breakfast at home was low, which may have implications for children’s school performance. Effort is needed to promote daily breakfast consumption among Saudi school children and to introduce appropriate interventions aimed at promoting daily breakfast consumption among Saudi children.
