Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

Summary

Factors underlying ethnic differences in the incidence of femoral fractures are not fully understood. Reference curves of femoral neck geometric parameters (FNGPS) between Changsha-Chinese women and three United States (US) ethnic groups of women varied by ethnicity, age, and measurement parameters. Further investigations might better explain fracture-rate differences.

Purpose

Osteoporotic fractures are associated with race, and the risk of femoral neck fractures is associated with FNGPs. We compared age-related FNGPs of Changsha-Chinese women with those of three ethnic groups of women in the US.

Methods

Data on 4236 Changsha-Chinese women and non-Hispanic Whites (NHWs), non-Hispanic Blacks (NHBs) and Mexican women (aged 20–91 years) from a laboratory database and research literature, were analyzed to measure their FNGPs: outer diameter (OD), cross-sectional area (CSA), averaged cortical thickness (ACT), endocortical diameter (ED), buckling ratio (BR), section modulus (SM), and cross-sectional moment of inertia (CSMI).

Results

The overall means of the OD, ED, SM, and CSMI of the Changsha-Chinese women were significantly lower than those of the NHWs. Their CSA, ACT, SM, and CSMI were significantly lower than that of the NHBs and the age-related reference curves of their CSA, ACT, SM, and CSMI were significantly lower than those of the NHWs, NHBs, and Mexican women. Their OD and ED reference curves were significantly lower than those of the NHWs and NHBs; their OD, CSA, and ACT reference curves were lower than those of the NHWs; and their CSA, ACT, and SM were significantly lower than those of the NHBs. However, their buckling ratio (BR) reference curve was significantly higher than that of the NHWs, NHBs, and Mexican women in the US.

Conclusion

Ethnic differences in the FNGPs of Changsha-Chinese women and US ethnic groups may explain differences in hip-fracture rates among different ethnic groups.
