am. Neonatal intensive care increased both survival rates and costs. For newborns weighing 1000 to 1499 g, the cost (in 1978 Canadian dollars) was $59,500 per additional survivor, $2,900 per life-year gained, and $3,200 per quality-adjusted life-year gained; intensive care resulted in a net economic gain when figures were undiscounted but a net economic loss when future costs, effects, and earnings were discounted at 5 per cent per annum. For infants weighing 500 to 999 g, the corresponding costs were $102,500 per additional survivor, $9,300 per life-year gained, and $22,400 per quality-adjusted life-year gained; intensive care resulted in a net economic loss. By every measure of economic evaluation, the impact of neonatal intensive care was more favorable among infants weighing 1000 to 1499 g than among those weighing 500 to 999 g. A judgment concerning the relative economic value of neonatal intensive care of very-low-birth-weight infants requires a comparison with other health programs.20:T535,Medical and technological advances in the care of infants with low birth weight (less than 2,500 grams, or 5 pounds, 8 ounces) and very low birth weight (less than 1,500 grams, or 3 pounds, 5 ounces) have substantially increased the survival rate for these infants and have led to concerns about the demands their care places upon their families and society. The dollar cost of the resources used disproportionately to care for low birth weight children is one measure of the burden of low birth weight. Using analyses of national survey data for 1988 for children ages 0 to 15, this article presents estimates of the direct incremental costs of low birth weight--costs of the resources used to care for low birth weight infants above and beyond those used for infants of normal birth weight. In 1988, health care, education, and child care for the 3.5 to 4 million children ages 0 to 15 born low birth weight between $5.5 and $6 billion more than they would have if those children had been born normal birth weight. Low birth weight accounts for 10% of all health care costs for children, and the incremental direct costs of low birth cost weight are of similar magnitude to those of unintentional injuries among children and in 1988 were substantially greater than the direct costs of AIDS among Americans of all ages in that year.21:T482,

Objective.

—Socioeconomic status (SES) is strongly associated with risk of disease and mortality. Universal health insurance is being debated as one remedy for such health inequalities. This article considers mechanisms through which SES affects health and argues that a broader and more comprehensive approach is needed.

Data Sources.

—Published articles surveyed using MEDLINE and review articles and bibliographies.

Methods and Results.

—Research is reviewed on the association of SES with health outcomes in different countries, including those with universal health coverage. Socioeconomic status relates to health at all levels of the SES hierarchy, and access to care accounts for little of this association. Other mechanisms are suggested and implications for policy and clinical practice are discussed.

Conclusion.

—Health insurance coverage alone is not likely to reduce significantly SES differences in health. Attention should be paid both in policy decisions and in clinical practice to other SES-related factors that may influence patterns of health and disease. (JAMA. 1993;269:3140-3145)
