The first years of life are the most dynamic period for childhood growth. There are limited data available on growth patterns of infants and children living in rural Latin America. The aim of this study was to describe the growth patterns from birth to 5years in children living in a rural District of tropical coastal Ecuador using data from a birth cohort of 2404 neonates.

Pregnant women were asked to participate in a birth cohort during their first antenatal visit. Data from 3184 children were used. The timing of the introduction of solids was reported by the mother from a questionnaire at 12 months postpartum, and cat...

A high response rate was observed at 12 years of age; 94.4% of the children examined at six years of age wer...

This study aimed to examine the reproducibility and validity of a new food frequency questionnaire (FFQ) used in a birth cohort study to estimate the usual consumption frequencies of foods during pregnancy. The reference measure was the average of three inconsecutive 24 h diet recalls (24 HR) administrated between two FFQs, and the reproducibility was measured by repeating the first FFQ (FFQ1) ...

We examine how income influences pre-school children’s cognitive and behavioral development, using new data from a birth cohort study of children born at the end of the 20 century. On average, low income children have lower PPVT scores, more mother-reported aggressive, withdrawn, and anxious behavior problems, and also more interviewer-reported problems with behavior, than more affluent childre...

We present 127 years of data on the physical stature of military conscripts born in Italy during 1854-1980, as well as an analysis of regional variations in height (for birth cohorts born during 1927-1980). The height of young men has increased in all regions of Italy. The secular trend and the regional changes in stature are correlated with economic growth and a general improvement of living c...
