Few studies in high fertility human populations support this hypothesis, and problems of phenotypic correlation can obscure the expected trade-off between reproduction and somatic condition. This cross-sectional study investigates whether greater reproductive effort is associated with reduced calcaneal bone mineral density (BMD) among female Tsimane forager-farmers of lowland Bolivia. We also investigate whether female Tsimane BMD values are lower than sex- and age-matched US reference values, despite the fact that Tsimane engage in higher physical activity levels that can increase mechanical loading. To measure calcaneal BMD, quantitative ultrasonography was performed on 130 women (mean ± SD age = 36.6 ± 15.7, range = 15–75) that were recruited regardless of past or current reproductive status. Anthropometric and demographic data were collected during routine medical exams. As predicted, higher parity, short inter-birth interval, and earlier age at first birth are associated with reduced BMD among Tsimane women after adjusting for potential confounders. Population-level differences are apparent prior to the onset of reproduction, and age-related decline in BMD is greater among Tsimane compared with American women. Greater cumulative reproductive burden may lower calcaneal BMD individually and jointly with other lifestyle and heritable factors. Fitness impacts of kin transfers in adulthood may determine the value of investments in bone remodeling, and thus affect selection on age-profiles of bone mineral loss. date: 2015-04 date_type: published publisher: John Wiley & Sons id_number: 10.1002/ajpa.22681 official_url: http://tse-fr.eu/pub/29031 faculty: tse divisions: tse language: en has_fulltext: FALSE doi: 10.1002/ajpa.22681 view_date_year: 2015 full_text_status: none publication: American Journal of Physical Anthropology volume: vol. 156 number: n° 4 place_of_pub: Hoboken, N.J. pagerange: 637-648 refereed: TRUE issn: 0002-9483 oai_identifier: oai:tse-fr.eu:29031 harvester_local_overwrite: oai_set harvester_local_overwrite: volume harvester_local_overwrite: number harvester_local_overwrite: issn harvester_local_overwrite: faculty harvester_local_overwrite: site harvester_local_overwrite: publisher harvester_local_overwrite: id_number harvester_local_overwrite: doi harvester_local_overwrite: creators_idrefppn harvester_local_overwrite: pending harvester_local_overwrite: title harvester_local_overwrite: place_of_pub harvester_local_overwrite: hal_id harvester_local_overwrite: hal_version harvester_local_overwrite: hal_url harvester_local_overwrite: hal_passwd oai_lastmod: 2023-11-20T13:41:35Z oai_set: tse oai_set: ut1c site: ut1 hal_id: hal-04302566 hal_passwd: 7tso#wbz hal_version: 1 hal_url: https://hal.science/hal-04302566 citation: Beheim, Bret A., Gurven, Michael, Kaplan, Hillard, Madimenos, Felicia C., Stieglitz, Jonathan and Trumble, Benjamin C.
