“…Body mass in black women age 65 and older is greater than that of white women of similar age (35,44). A recent analysis of the results of the second National Health and Nutrition Examination Survey found that the incidence of obesity in black women over the age of 45 years is higher than 60%, almost double the 3040% incidence found in white women (44).…”

A lower incidence of hip fracture in black women has been reported by several studies. The most frequently proposed explanations for this phenomenon have included a genetically greater bone mass, better preservation of bone due to the fact that certain populations of black women perform more physical labor, and the impact of other unidentified environmental and/or lifestyle factors. This retrospective study demonstrates that low body weight is as significant a risk factor for hip fracture in black women as it is in white women. Coupled with the known higher prevalence of obesity in the older black female population, the findings of this study suggest that differences in body weight may be a significant and possibly sufficient explanation for the lower incidence of hip fracture in black women.

“…Patterns of cortical bone loss in aging men and women have been well-documented in modern populations (Garn, 1970;Martin and Atkinson, 1977;Martin et al, 1980;Riggs et al, 1982Riggs et al, ,1983Riggs and Melton, 1986). There is substantial evidence that such changes occurred in pre-and protohistoric communities as well (Van Gerven et al, 1969;Van Gerven, 1973;Carlson et al, 1976;Eriksen, 1976), although the rate, pattern, and severity of bone loss apparently varies significantly by population (Moldawer et al, 1965;Nordin, 1966;Armelagos, 1969;Dewey et al, 1969a,b;Solomon, 1979;Perzigian, 1973;Mazess and Mather, 1975;Eriksen, 1976;Hayes, 1982, 1988;Harper et al, 1984;Evers et al, 1985;Martin et al, 1985).…”

Patterns of skeletal histologic change through time: Comparison of an archaic native american population with modern populations

1990

This paper compares patterns of histologic change in an archaic Native American population with those in modern white populations. Histologic sections were removed from core biopsies taken from the anterior femoral cortex of an archeologic sample of Pecos Indians. The data demonstrate many microstructural similarities between the Pecos and modern populations, even though they were genetically and culturally distinct. Pecos women had small Haversian canals and large osteon mean wall thickness, with no clear evidence of an intracortical bone volume deficit even in the older age groups, although significant marrow cavity expansion occurred in both males and females with age. No striking relationships were found between bone tissue changes and gross geometric changes with age. The data suggest that a more active life-style is associated with greater osteon mean wall thickness or osteon population density, but that it alone does not protect against significant bone loss on the cortical-endosteal surface.

“…However, more recent evidence provided by Mensforth and Latimer (1989) suggests that African-Americans tend to lose bone at rates that are comparable to Whites, but that they enter the older decades of life with a relatively and absolutely greater bone mass (see also Garn, 1970). Because of their greater initial bone mass, African-Americans of both sexes do not reach the fracture threshold until 25-30 years later than White men and women, and their incidences of clinical osteoporosis and femoral neck fracture are significantly lower than those recorded for other populations (Gyepes et al, 1962;Moldawer et al, 1965;Solomon, 1968Solomon, ,1979Engh et al, 1968;Farmer et al, 1984;Gordon, 1984;Bauer et al, 1986;Mensforth et al, 1987;Bauer, 1988;Mensforth and Latimer, 1989).…”

Age- and sex-related patterns of proximal femur trabecular bone loss have previously been used to establish radiographic reference standards for estimating age at death for human skeletal remains. Such standards are of interest to both anthropologists and forensic scientists. However, osteopenia as a physiological phenomenon is dependent on numerous genetic, environmental, and cultural factors. Thus, while general age- and sex-related trends can be clearly observed for trabecular bone loss, such patterns also demonstrate marked variation among individuals of both sexes at all ages. Moreover, clinical evidence shows that rates of bone loss are not steady but episodic, and that radiographically "normal" (i.e., young adult) patterns of trabecular bone architecture can also exist in femora of older individuals, particularly within samples of African origin. In this study, adult proximal femur radiographs were used to explore patterns of age- and sex-related proximal femur cancellous bone involution among a sample of 66 African-American individuals from the Terry collection (33 males and 33 females), ranging in age from 19 to 71 years. The proximal femur radiographs of these subjects were analyzed by digital image processing (DIP), and the results were compared to those obtained by laser linear densitometric analyses (LDA) previously performed on the same series (Macchiarelli et al., 1987). Results of LDA and DIP analyses indicate (a) more pronounced bone density decrease in females; (b) sex- and site-specific structural patterns of proximal femur trabecular bone loss; (c) a high level of individual variability, in which predicted age deviated from real age by as much as 22.26 (males) and 30.78 years (females); (d) a moderate linear correlation with age for all the variables analyzed; and (e) an average discrepancy between known age and predicted age (measured by root mean squared residual values) of 10.34 (males) and 12.71 years (females) for the most satisfactory DIP analysis parameter (recorded at the center of the femoral neck in the equalized images). With regard to estimating adult age at death from radiographic images of proximal femora, it is argued that the amount of useful age information reported for this criterion has been overestimated.
