Prevalence and contract

31.4% (13.6% over weight and you will sixteen.8% obesity), 32.0% off boys and you will 28.8% regarding girls, was in fact discovered to be over the necessary compliment pounds according to this new Whom source (Fig. 2). On top of that, brand new IOTF system advertised 23.1% (fourteen.1% heavy and 9.0% obesity), having twenty-two.5% for the boys and you may 23.8% in the girls. Irrespective of sex and you can classification system, overweight and you may being obese try high in both metropolitan and personal universities as opposed to those out of rural and social schools (Dining tables dos and you can 3). Concurrently, ow/ob are large one of youngsters when compared with elderly of them. Differences in the new frequency out-of obese and you can being obese between the Exactly who and you can IOTF system ranged off cuatro.5 to help you 10.9%. Having carrying excess fat alone, this type of rates ranged out-of 2.2 so you can 9.3%. These variations was basically higher inside the boys compared to girls.

The entire kappa well worth was 0.83[95%CI: 0.829–0.834] (solid agreement) involving the Which as well as the IOTF system (Dining table 4). By years, kappa had a tendency to decrease in old years, primarily shortly after 8 years old, reporting a substantial concordance.

Multilevel analysis

On haphazard effect region, the newest partition difference was derived from the latest null design (no explanatory details included) and adjusted designs (Dining table 5, Dining table six). The new ICC on scholar level to the Exactly who system said quite over ninety-five.9% of the total variance. From the university/civil and you may municipal by yourself, the newest ICC are seven.03 and step one.6%, correspondingly. These figures in the beginner, school/municipal and you may civil alone height was basically ninety five.eight, 5.6 and you can step 1.6% respectively to the IOTF program. In spite of the lowest explained difference in school and you can local government, new multilevel model (and most of the predictors) try significantly preferred across the single model (not accounted for clustering data) and you will do better than this new null model (zero predictors). It indicates one to BMIZ behaved as the established findings, with some number of clustering in the university and you can civil level.

Table six Multilevel linear regression model of body mass index Z-score by using the IOTF classification system, on analytical 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

We looked at this new frequency off ow/ob along side municipalities utilizing the Exactly who and you will IOTF expertise. This new Moran’s Index on the mutual over weight and you may carrying excess fat and obesity by yourself were 0.434 and 0.359, correspondingly (p-well worth = 0.001) utilising the Whom system. This type of numbers utilizing the IOTF program was 0.561 and you can 0.552 (p-well worth = 0.001). Then, the local clustering predicated on Getis-Ord Gi* understood high municipal clusters to own obese and you will being obese (Fig. 3).
