Abstract
Using data for sixty less‐developed countries, we constructed a causal model in which medical care, nutrition, status of women, and socioeconomic development are examined as determinants of infant mortality. Social and economic development are treated as exogenous variables; medical care, nutrition, and status of women are viewed as variables endogenous to the model. The model is tested by maximum likelihood methods. Results indicate that good nutrition and the presence of informally trained health care personnel, i.e., midwives, are more significantly related to low rates of infant mortality than are the employment status of women and the presence of formally trained health care personnel such as physicians and nurses. The general level of social and economic development conditions these relationships.
