The aim of this study was to assess reproducibility in four Colombian cities of the results obtained on food insecurity (INSA) comparing it with the factorial and criterion validity of the Food Security Perceptions scale (EPSA) and the Latin American and Caribbean (ELCSA) methods in homes from urban and rural area based on the usual consumption of energy for all household members. The reproducibility was 0.51 for EPSA and 0.56 for ELCSA. The sensitivity of the EPSA was between 39.6% and 40.5% and for the ELCSA between 62.6% and 62.2%. The agreement against the reference for the EPSA was between 0.10 and 0.18, for ELCSA was between 0.09 and 0.13. The efficiency of the two tests as a global measure of reliability is just greater than the probability in a coin toss. The results of these scales should be used conservatively.

a study was carried out in Lebrija (Colombia) to evaluate the impact of two strategies implemented in families with school-age children to increase the consumption of fruits and vegetables at home. Sixteen homes were intervened with the A strategy while twenty three homes were intervened with a B strategy. Thirty four homes served like controls. These strategies included, among others, informative shops, preparation of recipes, activities in group and evaluation of tasks. At the initiation, 3.0% of the intervened homes consumed five or more portions increasing to 26.3% at the end of the intervention, an increment of 8.8 times. In the control group the consumption of five or more daily portions was of 2.0% at the beginning and 0.0% at the end. There was no difference between strategy A and B in the increase in consumption (0% to 23.5% and 4.3% to 28.6%, respectively. The two evaluated strategies had positive impact, the A on the consumption of fruits and vegetables, the B on the consumption of fruits.
