Mapping access to food in a deprived area: the development of price and availability indices.

OBJECTIVE: To develop and map indices to illustrate variation in the cost and availability of healthy food. DESIGN: Two contiguous wards in London were selected by virtue of their high Carstairs deprivation scores. A 2-km area was defined around a randomly chosen central point. All retail outlets selling food within the area were visited and their location recorded. A list of foods, acceptable to the local ethnically diverse population, which met current dietary guidelines, was devised. Data on the availability and price of 71 food items were collected. Indices were developed using SPSS and mapped using Geographic Information System (GIS) software. RESULTS: Information on availability and prices were collected from 199 outlets. The mean price index shows how expensive a shop is relative to other shops in the area. The least cost index shows the relative expense of a shop using the cheapest ways of buying their range of foods. Shorthand indices were tested, using data on 19 of the 71 prices. Availability indices are also discussed, including a green availability index and a fresh green availability index. Illustrative maps of the shop locations and the mean price index and fresh green availability index are shown. CONCLUSIONS: Data can be collected and indices developed which indicate geographic variation in shop 'expensiveness', and in the price and availability of healthy food. GIS software can be used to map these indices, to identify areas with high food prices or low availability.

A minimum income for healthy living.

BACKGROUND: Half a century of research has provided consensual evidence of major personal requisites of adult health in nutrition, physical activity and psychosocial relations. Their minimal money costs, together with those of a home and other basic necessities, indicate disposable income that is now essential for health. METHODS: In a first application we identified such representative minimal costs for healthy, single, working men aged 18-30, in the UK. Costs were derived from ad hoc survey, relevant figures in the national Family Expenditure Survey, and by pragmatic decision for the few minor items where survey data were not available. RESULTS: Minimum costs were assessed at 131.86 pound sterling per week (UK April 1999 prices). Component costs, especially those of housing (which represents around 40% of this total), depend on region and on several assumptions. By varying these a range of totals from 106.47 pound sterling to 163.86 pound sterling per week was detailed. These figures compare, 1999, with the new UK national minimum wage, after statutory deductions, of pound 105.84 at 18-21 years and 121.12 pound sterling at 22+ years for a 38 hour working week. Corresponding basic social security rates are 40.70 pound sterling to 51.40 pound sterling per week. INTERPRETATION: Accumulating science means that absolute standards of living, "poverty", minimal official incomes and the like, can now be assessed by objective measurement of the personal capacity to meet the costs of major requisites of healthy living. A realistic assessment of these costs is presented as an impetus to public discussion. It is a historical role of public health as social medicine to lead in public advocacy of such a national agenda.
