Prevalence and you can agreement
29.4% (thirteen.6% fat and you will 16.8% obesity), 32.0% away from boys and you can twenty eight.8% off girls, was found to be across the necessary fit weight considering the fresh new Whom source (Fig. 2). On top of that, the IOTF system said 23.1% (fourteen.1% obese and you may 9.0% obesity), that have 22.5% into the boys and you can 23.8% inside girls. Irrespective of sex and you may category system, heavy and being obese are large both in urban and private schools than those regarding rural and you can public schools (Dining tables dos and you may step three). Concurrently, ow/ob are highest certainly youngsters when comparing to earlier ones. Variations in the brand new incidence off fat and obesity amongst the Just who and you can IOTF system varied away from 4.5 to 10.9%. To have carrying excess fat alone, such figures ranged lГ¦se artiklen away from dos.dos so you’re able to nine.3%. These types of variations had been higher when you look at the boys compared to girls.

Dining table step three Frequency regarding obesity of college-old children according to the Just who and you may IOTF growth references, regarding the analytical dataset, Este Salvador,
The overall kappa well worth is 0.83[95%CI: 0.829–0.834] (solid arrangement) between the Just who therefore the IOTF program (Desk 4). By many years, kappa had a tendency to decrease in elderly decades, mainly immediately after 8 years old, reporting a hefty concordance.

Multilevel analysis
Regarding random impression area, the new partition variance is actually based on brand new null design (no explanatory details provided) and you will adjusted models (Dining table 5, Table 6). Brand new ICC in the college student height with the Exactly who program informed me a little over 92.9% of your full difference. In the college or university/civil and you can civil alone, the latest ICC is actually eight.03 and step one.6%, correspondingly. These types of data in the college student, school/municipal and you may municipal alone peak was ninety-five.eight, 5.six and step 1.6% respectively for the IOTF system. Inspite of the lower said difference at school and town, the fresh multilevel design (plus the predictors) try notably preferred over the solitary model (not taken into account clustering analysis) and you will carry out better than the fresh new null design (zero predictors). This means you to definitely BMIZ behaved due to the fact depending observations, with some amount of clustering from the college or university and you can civil level.

Desk 6 Multilevel linear regression model of body mass index Z-rating utilising the IOTF group system, on the analytical dataset, Este 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 analysis
We looked at the brand new prevalence away from ow/ob across the municipalities using the Whom and you will IOTF expertise. The fresh new Moran’s Index on the mutual overweight and you may carrying excess fat and you may carrying excess fat alone were 0.434 and 0.359, correspondingly (p-worth = 0.001) by using the Whom program. These data using the IOTF system was basically 0.561 and 0.552 (p-well worth = 0.001). After that, your neighborhood clustering predicated on Getis-Ord Gi* known significant civil groups to have overweight and being obese (Fig. 3).
