  1. Abbreviated measures of food sufficiency validly estimate the food security level of poor households : Measuring household food security.

    Article - En anglais

    This study was designed to develop an abbreviated method that captures both the qualitative and quantitative dimensions of household food security (HFS).

    Women in poor and very poor households (n=238) in a peri-urban barrio in Caracas, Venezuela, provided data on food availability and their perception of food resource constraints and hunger experiences within the home.

    Socioeconomic data and food-related behavior that may predict HFS levels were gathered.

    On average, the top 12 food contributors of energy provided 81% and predicted more than 90% of the variation in households'total energy availability using stepwise regression analysis.

    On the other hand, a 4-point 12-item scale was shown to have face, content and construct validity with reiterative testing, factor analysis and a Chronbach's alpha coefficient of 0.92.

    Assessing predictors of energy availability together with a self-perceived HFS scale may provide a valid and reliable method for identifying and monitoring food security levels among poor urban households.
