Cross-cultural correlations of childhood growth and adult breast cancer.

Abstract：

:International differences in breast cancer incidence and mortality, and studies on Japanese migrants to the United States, point to the importance of environmental factors, including diet and nutrition, in the etiology of breast cancer. Some studies have suggested that dietary patterns in early life are important to the long-term risk of breast cancer. Given that human growth is partially a function of early dietary intake, cross-cultural correlations between breast cancer rates and anthropometric variables measured at different times in childhood provide additional information about the association of early nutrition and cancer. In this study, the associations between food consumption and anthropometric variables, and childhood growth patterns (attained size at age) and adult breast cancer rates, were considered. Data from cross-sectional growth studies conducted during the years 1956-1971 on children aged 6-18 years were obtained for age-specific stature, sitting height, weight, triceps skinfold thickness, arm and chest circumferences, and biacromial and biiliac diameters. National food consumption data were obtained from the United Nations Food and Agriculture Organization (FAO) and socioeconomic status indicators from the United Nations Children's Fund (UNICEF). Cancer incidence data for the years 1972-1977 were obtained from regional cancer registries reported by the International Agency for Research on Cancer (IARC), and mortality data for 1978 were obtained from national cancer registries around the world. Significant correlations were seen between national food consumption data and childhood growth (attained size at age); between cancer incidence and age-specific stature (r = 0.68), weight (r = 0.59), triceps skinfold thickness (r = 0.78), and biacromial width (r = 0.84); and between mortality and age-specific stature (r = 0.77), weight (r = 0.75), and biacromial width (r = 0.78). In general, the correlation coefficients of the observed anthropometric variables with breast cancer increase with increasing age and become highly significant at ages 13-14 years, reflecting cumulative childhood nutritional intake.
