Eating patterns of 549 Mexican American mothers were identified using dietary data from the United States Hispanic Health and Nutrition Examination Survey. These eating patterns were then used to investigate the relationship between maternal diet and infant birth weight. Principle components factor analysis was used to determine the structure of the maternal eating patterns. Seven distinct eating patterns were identified: nutrient dense, traditional, transitional, nutrient dilute, protein rich, high fat dairy, and mixed dishes. Stepwise multiple regression analysis was used to identify those eating patterns associated with birth weight. In addition to eating patterns, regression variables included body mass index, hemoglobin, gestational age at delivery, maternal age, infant gender, acculturation, marital status, income, education, and smoking during pregnancy. Regression results indicated that the nutrient dense (fruits, vegetables, low fat dairy, etc.) and protein rich (low fat meats, processed meats, and dairy desserts, etc.) eating patterns were associated with increased birth weight and that the transitional eating pattern (fats and oils, breads and cereals, high fat meats, sugar, etc.) was associated with decreased birth weight. Study findings suggest that the eating pattern methodology may be an appropriate tool for analyzing food frequency data in the investigation of diet and health relationships and for targeting dietary interventions.

One hundred seventy-five members of a rural convalescent hospital participated in a study which investigated, through path analysis, the impact of occupational stress on an organizational member's decision to leave the organization. This article reports the findings of this analysis with respect to the nurse's aides and other lower level support personnel categories employed in the hospital (N = 72). Strong support was found for the proposition that the level of perceived occupational stress reported by these employees would be highly instrumental in their decisions to leave.

The smoking practices of a national sample of Mexican-American mothers and the resulting effects of those practices on birth weight were examined. Data were from the Hispanic Health and Nutrition Examination Survey conducted by the U.S. National Center for Health Statistics during 1983-1984. We found that 24% of the mothers had smoked during their pregnancy, with a mean of 11 cigarettes per day. Infants of these women weighed 101 g less at birth than did infants of nonsmoking mothers and had a low birth weight rate of 8.0% compared with the 5.1% low birth weight rate for the sample as a whole. Multiple regression results indicate a 7.4 g decrease in birth weight for each cigarette smoked per day during pregnancy. Cultural factors that promote a low birth weight rate for Mexican-Americans that is comparable to that of non-Hispanic whites despite increased rates of poverty and inadequate health care do not protect against the insidious effects of cigarette smoking.
