Abstract
BackgroundIncreasing BMI is associated with increased risk of mortality, cardiovascular disease, and some cancers whereas a lower BMI is associated with an increased risk of mortality, postsurgical complications, infection, and length of hospital stay as a result. Locomotion is a unique feature of the animal kingdom. It allows individuals to meet others, to find better food and a better climate, to pursue prey, or to escape impending danger. The aim of the current study was to determine the correlation between body mass index (BMI) and spatial gait parameters in primary school children.ResultsA total of 320 healthy children from primary schools were enrolled. The participants comprised 185 boys and 135 girls with a mean age of 10.05 ± 0.95 years, mean weight of 38.49 ± 12.2 kg, a mean height of 139.25 ± 10.12 cm, and a mean BMI of 19.35 ± 4.55 kg/m2. BMI was evaluated by the KINLEE Electronic Personal Scale with Height Measurement and CDC charts for boys and girls and equation of BMI. Spatial gait parameters were evaluated by a pediatric run-based anaerobic sprint test with an Omron pedometer to assess step and stride length.Statistical analysis was performed by Pearson’s correlation coefficient to study the relationship between variables. A correlation was performed between the variables, and the coefficient of determination was calculated. The significance level was set at 5% for all analyses. There was no significant relationship between BMI and spatial gait parameters (step length and stride length) (r = 0.008, p = 0.88 and r = 0.02, p = 0.7, respectively).ConclusionAccording to the results, we concluded that there was no significant relationship between BMI and the measured gait parameters (step length and stride length).
Highlights
Increasing body mass index (BMI) is associated with increased risk of mortality, cardiovascular disease, and some cancers whereas a lower BMI is associated with an increased risk of mortality, postsurgical complications, infection, and length of hospital stay as a result
BMI can be interpreted for children and teens in different way, but can be calculated using the same method as that used for adults, as there is a relationship between the amount of body fat and age and a difference in the accumulation of fat between both sexes
The aim of the current research was to study the relationship between BMI and gait parameters
Summary
Increasing BMI is associated with increased risk of mortality, cardiovascular disease, and some cancers whereas a lower BMI is associated with an increased risk of mortality, postsurgical complications, infection, and length of hospital stay as a result. The aim of the current study was to determine the correlation between body mass index (BMI) and spatial gait parameters in primary school children. Body mass index (BMI) indicates the association between weight and height and is mainly used to provide an assessment of healthy, malnourished, or obese individuals [1]. BMI can be interpreted for children and teens in different way, but can be calculated using the same method as that used for adults, as there is a relationship between the amount of body fat and age and a difference in the accumulation of fat between both sexes. The CDC growth chart can be used to establish these sex- and age-related differences, and shows the BMI as a percentile ranking from 2 to 19 years [6]. Klein et al classified BMI percentiles into five categories as follows: underweight, < 5 percentile; normal weight, 5–84 percentile; overweight, 85–94 percentile; obese > 95 percentile; and severe obesity, > 99 percentile [7]
