RESUMO
The nutritional status of at-risk groups is usually monitored using health statistics. This approach has limitations as individuals are identified only after they have been afflicted by morbidity. In Jamaica, national surveys are carried out in which expenditure data on all consumption items are collected. We used these data to monitor food accessibility in at-risk groups. The identification of decreases in accessibility levels relative to requirements would enable timely intervention before there is a deterioration in nutritional status. We analysed the data from the survey of 3861 households conducted by Statistical and Planning Institutes of Jamaica in 1989. Using the food expenditure data, per capita energy and protein accessibility levels were determined. The mean energy and protein accessibility levels for the sample were 2170 Cals and 64 g, respectively. The results showed that the per capita accessibility levels of 20 percent and 9 percent of the households were less than half of requirments for energy and protein, respectively. The situation was worse in rural areas than in urban centres. However, the accessibility levels may have been underestimated as the data did not include meals bought and consumed away from the home, which may be significant to some households. We believe that the use of data from these surveys is a cost-effective way to monitor nutrient accessibility in Jamaica
