“…The body mass index (BMI) was calculated as P/T 2 (P is weight in kilograms and T is height in metres) and the anthropometric weight status defined according to International Obesity Task Force (IOTF) standards for each subject (Bahchachi et al, 2017). The curve passing through BMI equal to 25 at the age of 18 years defines the threshold of overweight, obesity included (IOTF 25) and the percentile curve passing through BMI equal to 30 at the age of 18 years defines the threshold of obesity.…”

“…Obesity is defined as an abnormal or excessive accumulation of body fat that represents a health risk. It is caused by ingesting more energy than is expended over a long period of time (Bahchachi et al, 2017). In recent decades, the prevalence of obesity and overweight has increased dramatically worldwide in children and adults (Makoutode et al, 2017).…”

The policy for the management of obese children in Congo is almost non-existent. The present study aims at determining the level of acceptability, accessibility and effectiveness of the form of physical exercise session best suited for the management of obese school children in Brazzaville. Methods: The present study was an intervention study, carried out with 23 overweight students from eight secondary schools in the city of Brazzaville. The participants were subjected to two physical exercise sessions (aerobics alone and then, aerobics and muscle strengthening) during one week. Data were collected using a questionnaire. The form of the session was considered acceptable if its assessment based on 6 items scored at least 13.6 out of a total of 17 points; accessible if its assessment based on 5 items scored 14.4 out of a total of 18 points. It was considered effective if it met 4 of the physiological criteria. The level of acceptability of the aerobics and muscle strengthening session was significantly higher than that of the aerobics session alone (14/23 or 61% versus 4/19 or 17%; P = 0.03). PCA identified two components (percent weight loss %PP and energy expenditure DE) in axis 1 that had a satisfactory loading factor of 0.70. The results of this study put the acceptability, accessibility and effectiveness of an intervention program based on aerobics and strength training. This program could be recommended as a non-pharmacological means in the management of an obese adolescent population.

“… 18 The individual data consisted of sex, age in completed years, and measured height and weight recorded to one decimal place. Individual data for 7157 Algerian children aged 6–18 were also kindly made available, 19 consisting of sex, decimal age, and measured height and weight to one decimal place. For these individual data, body mass index was calculated as

, and country‐age‐sex‐specific prevalence rates for overweight (including obesity) and obesity by CDC, IOTF and WHO were calculated for each completed year of age in each country, with 26 groups for China, Mexico, USA, UK and Russia, and 24 for Algeria.…”

Background: Prevalence rates of child overweight and obesity for a group of children vary depending on the BMI reference and cut-off used. Previously we developed an algorithm to convert prevalence rates based on one reference to those based on another. Objective: To improve the algorithm by combining information on overweight and obesity prevalence. Methods: The original algorithm assumed that prevalence according to two different cut-offs A and B differed by a constant amount dz on the z-score scale. However the results showed that the z-score difference tended to be greater in the upper tail of the distribution and was better represented by b Â dz, where b was a constant that varied by group. The improved algorithm uses paired prevalence rates of overweight and obesity to estimate b for each group. Prevalence based on cut-off A is then transformed to a z-score, adjusted up or down according to b Â dz and back-transformed, and this predicts prevalence based on cut-off B. The algorithm's performance was tested on 228 groups of children aged 6-17 years from 20 countries.Results: The revised algorithm performed much better than the original. The standard deviation (SD) of residuals, the difference between observed and predicted prevalence, was 0.8% (n = 2320 comparisons), while the SD of the difference between pairs of the original prevalence rates was 4.3%, meaning that the algorithm explained 96.7% of the baseline variance (88.2% with original algorithm). Conclusions:The improved algorithm appears to be effective at harmonizing prevalence rates of child overweight and obesity based on different references.

“…In Tiaret, in 2016, the prevalence reached 8.18 % of 6 to 11 years old 20 . Two other surveys, conducted in 2017 and 2018 in Constantine among children and adolescents aged 6-18 years, showed a prevalence of overweight and obesity in girls and boys together of 13.7 and 3.0 %, respectively 21,22 . In 2021, a recent study in Bejaia found a prevalence of overweight and obesity to be 3.3 % among adolescents of 11 to 23 years old 23 .…”

Aim: This study aimed to describe the behavior, eating habits, and lifestyle of schoolchildren from different regions of Bejaia, and to evaluate their food consumption on the one hand and their Physical Activity Level (PAL) on the other hand. Methods: This study involved children (n = 240, B/G = 120/120), aged from 6 to 12, that are enrolled in different institutions (primary schools, colleges) in different regions of Bejaia. The children's body weight and height were measured (BMI), and their eating habits and level of physical activity were assessed using adapted questionnaires. Food consumption was estimated by the 24-hour recall method. Results: Results showed observable BMI rise including drastic changes in BMI Z-score as a function of age, height and mainly weight, BMI Z-score values were between 0 and +2 in overweight for obese girls and boys and less than +1 for normal-weight girls and boys. The PAL evaluation was low in overweight and obese children compared to normal-weight children. The correlation test showed a positive correlation between BMI and PAL in both sexes. According to the results of the dietary habits, the frequency of consumption of the different food groups distributed according to the fourth daily intakes (breakfast, lunch, dinner and snacking between meals) was very rich in carbohydrates and fats in overweight and obese children, compared to normal-weight children and according to the recommended threshold. Conclusion: This study shows that there is an increase in BMI values, high BMI Z-scores in overweight and obese children compared to normal-weight children. Children have bad eating habits (snacking between meals, consumption of fast food and sugary drinks). These habits may act as obesity promoting factors when associated with sedentary activities. Keywords: Children, overweight-obesity, normal-weight, BMI, Physical Activity Level, food habits, food consumption.
