(Z-score for height-for-age), WHZ (Z-score for weight-for-height) were calculated from EPI INFO. Scores over 6Z or under –6Z (Z being the number of standard deviations from the sample) were assumed outliers and discarded from the analysis. The Z-score of –1z is used to define children with acute malnutrition, while the Z score of –2z or below is used to define children with chronic malnutrition.
Frequencies were generated from EPI INFO directly. Survival analysis was done through the generation of life tables, a methodology that re-constructs breast feeding and weaning patterns using SPSS-X at UPCH. Graphs showing the results of the above analysis were generated through MS Excel.
For this final survey forty six clusters were surveyed. This was a total of 464 households with children under the age of three years. See Table 3. for a geographic distribution (by REDES) of the sample in the project areas.

The survey among mothers with children less than 3 years of age had 80 questions (but some sections were not included if it was not relevant to that geographic region i.e. in areas where malaria is not endemic those questions were not asked). A total of 464 mothers (or other parent) were surveyed and the results are presented below.
NOTE: 455 (98.1%) of the respondents were the biological mother.
The mean age among surveyed mothers with children less than 3 years of age is 25.8 years. Seventy five (16.2%) of the 464 mothers who responded to this question were younger than 20 years of age. This is an increase from the baseline results of 14.3%. It has been noted from health statistics and other studies that Region San Martín is one of the regions with the highest fertility rate among adolescents1. Additionally, MINSA has confirmed that the rate of adolescent pregnancies has increased in the past few years. Thirty one (6.7%) of the mothers interviewed were 40 years or older. This percent has decreased from the baseline of 7.5%.
