We examined the association between memory difficulty and BMD in US adults.<\/jats:p>\n <\/jats:sec>\n \n Methodology:<\/jats:title>\n This cross-sectional study identified 4383 individuals (2581 [58.9%] males). Memory difficulty data were collected during a face-to-face interview. Femoral neck, total hip, and lumbar spine BMD were measured by a Hologic QDR-4500A fan-beam dual-energy X-ray absorptiometry (DXA); BMD T-scores were calculated using the established method.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The average age and body mass index for study participants were 39.5 years (SD = 13.4 years) and 28.6 kg\/m\n 2<\/jats:sup>\n (SD = 6.6 kg\/m\n 2<\/jats:sup>\n ), respectively. In both unadjusted and adjusted models, memory difficulty was associated with decreased femoral neck and total hip BMD T-scores (all\n P<\/jats:italic>\n < 0.05), but not with lumbar spine BMD T-scores. These associations were identical for males and females (all\n P<\/jats:italic>\n interaction by sex >0.100). The negative association between memory difficulty and hip BMD appeared to be stronger in individuals <50 years old than in those \u226550 years old (\n P<\/jats:italic>\n interaction <0.001).\n
