Heat or eat? Cold-weather shocks and nutrition in poor American families.

OBJECTIVES The authors sought to determine the effects of cold-weather periods on budgets and nutritional outcomes among poor American families. METHODS The Consumer Expenditure Survey was used to track expenditures on food and home fuels, and the Third National Health and Nutrition Examination Survey was used to track calorie consumption, dietary quality, vitamin deficiencies, and anemia. RESULTS Both poor and richer families increased fuel expenditures in response to unusually cold weather. Poor families reduced food expenditures by roughly the same amount as their increase in fuel expenditures, whereas richer families increased food expenditures. CONCLUSIONS Poor parents and their children spend less on and eat less food during cold-weather budgetary shocks. Existing social programs fail to buffer against these shocks.
