Persistence of growth stunting in a Peruvian high altitude community, 1964-1999.

The growth of children living in Nuñoa, a Peruvian high-altitude community, was studied over a 35-year period using data collected in 1964 and 1999. There had been evidence of a secular trend in growth in the mid-1980s, but this was before a period of sociopolitical upheaval lasting until the late 1990s partly linked to the activities of the Shining Path group and the Peruvian government's response. Anthropometric data for 576 children examined in 1964-1966 were compared with data from 361 children examined in 1999.

Ethnic variation in the size of infant at birth.

The impact of ethnicity and other maternal factors (BMI, parity, glucose tolerance, gestational age) on the size of the infant at birth was investigated in a relatively low socioeconomic status, multi-ethnic population at San Francisco General Hospital. A sample of 2,069 infants born to mothers of black, non-Hispanic white, Hispanic, and Chinese descent and whose mothers had received prenatal care at San Francisco General Hospital were studied. Maternal size, pregnancy history, and blood glucose were determined prenatally at 26-28 weeks gestation.
