Differences in BMI-for-age <i>z</i> score change per year over childhood among urban Amazonian children (2007–2012), according to age groups and baseline health indicators.

a<p>Totals may be less than 346 for children ≤5 years and less than 391 for children >5 years at baseline because of missing values. Missing observations among the covariates were included in the multiple models by creating missing-value categories.</p>b<p>BMI-for-age <i>z</i> scores (BAZ) were calculated according to the WHO Child Growth Standards for children ≤5 years and the WHO Growth Reference Data for children >5 years.</p>c<p>Mean differences in BAZ change per year and their 95% confidence intervals (CI) were from mixed-effect linear regression models. For each age group, unadjusted differences refer to preliminary models that included each child health indicator with adjustment for sex. Fully adjusted differences were estimated from models including CRP and all other health indicators with further adjustment for household wealth, maternal age, birth weight, and HAZ at baseline. <i>P</i><0.05 for results in bold.</p>d<p>C-reactive protein categories were distributed as follows: 1^st tertile: 0.01–0.15 mg/L; 2^nd tertile: 0.16–0.38 mg/L; 3^rd tertile: 0.39–1.00 mg/L; >1 mg/L: 1.01–9.81 mg/L.
