Nutrition Survey


Fourteen mothers completed a nutrition survey for their child. Six of the children were 1 to 3 years of age, four were 4 to 8 years of age, and 4 were 9 to 13 years of age. The age ranges were chosen based on the data for the Recommended Dietary Allowance (RDA) for children in the United States.

The mothers were interviewed by Maria, a local Gigante mother, and the data input was performed by Sarah, an EMT from the United States.

A program was designed based on data in Bowes and Church's book on the nutritional value of common foods. Portion sizes were determined by showing mothers common measurement tools for baking.
Data analysis was limited to calories, carbohydrate, protein, fat, fibre, sodium, calcium, iron, and the common vitamins. The result obtained for each nutrient was compared to the US RDA for age and a percentage calculated. The percentages within each age group were averaged. The data for those nutrients with an abnormal result is shown in the graph below.
The data is subject to a variety of limitations. None of the volunteers had prior experience. However, the dietary choices in Gigante are limited, the serving sizes were standardized, and the volunteers were patient and thorough with the protocol. My review of the raw data suggested that even for the small sample size, the trends were likely valid. There were few obvious "outliers" in the raw data.

The results of this survey will be presented to interested mothers in the community at an advertised "charla" on nutrition next week. Dr. Mariana will lead the discussion on nutrition and the data will serve as a talking point.
