Frequency and contract
30.4% (13.6% heavy and you can sixteen.8% obesity), 32.0% away from boys and you can twenty eight.8% regarding girls, were seen to be along side necessary suit lbs according to the latest Just who site (Fig. 2). Additionally, the fresh IOTF program reported 23.1% (14.1% obese and you may 9.0% obesity), that have 22.5% within the boys and 23.8% during the girls. Irrespective of sex and you may class system, fat and being obese is actually highest in both metropolitan and private schools than others off rural and you will social colleges (Tables dos and you can 3). On the other hand, ow/ob was large one of younger children in comparison with older of these. Variations in the fresh frequency out of overweight and you can obesity involving the Just who and you will IOTF system varied from 4.5 to 10.9%. Having carrying excess fat by yourself, these types of data varied regarding dos.2 in order to nine.3%. These differences was in fact high within the boys compared to girls.

All round kappa worth is actually 0.83[95%CI: 0.829–0.834] (good contract) within Who and the IOTF system (Desk cuatro). Because of the age, kappa tended to decrease in older ages, mostly after 8 years old, revealing a substantial concordance.

Multilevel investigation
On the arbitrary perception part, the newest partition variance are derived from the brand new null design (no explanatory variables integrated) and you may adjusted designs (Desk 5, Table six). The latest ICC in the pupil level to your Exactly who system explained somewhat more than ninety-five.9% of the complete variance. At college or university/civil and you may civil alone, the ICC was 7.03 and step one.6%, correspondingly. These data in the pupil, school/civil and you will municipal alone peak was indeed ninety-five.7, 5.six and you may step 1.6% correspondingly for the IOTF program. Regardless of the lower told me variance at school and you can town, this new multilevel model (as well as every predictors) try notably common across the unmarried design (perhaps not accounted for clustering investigation) and you will perform a lot better than the latest null design (zero predictors). This means one BMIZ behaved as the oriented findings, with some quantity of clustering on school and you can municipal level.

Table six Multilevel linear regression model of body mass index Z-get with the IOTF category program, regarding the logical dataset, El Salvador,
The fixed effects in both models showed similar conclusions. Boys, children attending urban schools, and children from private schools had higher BMIZ than girls, rural and public school children. The regression coefficients by sex were higher using the WHO system (0.14, p-value < 0.01)>
Spatial study
I tested the latest prevalence out-of ow/ob along side municipalities making use of the Which and you will IOTF assistance. This new Moran’s Index for the combined fat and you can obesity and you can carrying excess fat alone were 0.434 and you may 0.359, respectively (p-well worth = 0.001) with the Whom program. These types of rates utilizing the IOTF system were 0.561 and you will 0.552 (p-well worth = 0.001). Then, nearby clustering considering Getis-Ord Gi* recognized significant civil groups to own heavy and you can being obese (Fig. 3).
