“…This result is consistent with previous studies of postmenopausal women [6,22,23]. Most studies that have examined the relationship between SEP and bone health have used data from postmenopausal women, and only a few studies have examined the relationship in men [3,24,25]. In fact, those that have examined men have shown results inconsistent with our study: Elliot et al [25] showed an inverse relationship between SEP and BMD in a Caucasian male population, where men with higher SEP had lower BMD.…”

While studies suggest that socioeconomic position (SEP) influences bone health and risk of osteoporotic fracture in postmenopausal women, few studies have simultaneously examined gender and menopause differences as they relate to SEP and bone health. Here, we investigated the relationship between SEP and bone mineral density (BMD) among Korean men, premenopausal women, and postmenopausal women using the BMD data set (n = 9,995) of the Korean National Health and Nutrition Examination Survey IV. The relationship between SEP and BMD was estimated using analysis of covariance (ANCOVA); adjustments were made for age and body mass index (BMI) in the multivariate models. The relationship between SEP and osteoporosis prevalence was estimated using logistic regression. Relative index of inequality (RII) in osteoporosis was estimated using log-binomial regression. ANCOVA (adjusted for age and for age plus BMI) showed a significant positive association between SEP and BMD among men and postmenopausal women. Logistic regression showed a significant negative association between SEP and osteoporosis prevalence among men and postmenopausal women but not in premenopausal women. The RII, estimated by log-binomial regression, showed the impact of SEP on osteoporosis to be significant in men and postmenopausal women (p < 0.05) but not in premenopausal women. Overall, low SEP was associated with both low BMD and high risk of osteoporosis among men and postmenopausal women. Efforts to reduce the economic burden of morbidity and mortality from osteoporosis should target men and postmenopausal women with low SEP.

“…Similar results were observed in a study of middle-aged Norwegian women [8]. Nabipour et al showed that Australian elderly men who are married had a higher bone mineral content than those who lived alone [9]. Further, a recent study on Chinese elderly individuals assessed the relationship between osteoporosis and the amount of received social support [10].…”

“…Because marital status was associated with bone density and fracture in previous studies [6–9], we also controlled for marital status. This variable was categorized into two groups: (1) those who were currently not married (widowed, divorced or never married) and (2) those who were currently married.…”

Contingent association between the size of the social support network and osteoporosis among Korean elderly women

ObjectiveTo investigate the association between the number of personal ties (or the size of the social support network) and the incidence of osteoporosis among older women in Korea.MethodsData from the Korean Urban Rural Elderly Study were used. Bone density was measured by dual-energy X-ray absorptiometry at the lumbar spine (L1–L4) and femur neck. T-score, the standardized bone density compared with what is normally expected in a healthy young adult, was measured and the presence of osteoporosis was determined, if the T-score was < -2.5. The social support network size was measured by self-responses (number of confidants and spouse).ResultsOf the 1,846 participants, 44.9% were diagnosed with osteoporosis. The association between the social support network size and the incidence of osteoporosis was curvilinear in both bivariate and multivariate analyses. Having more people in one’s social support network size was associated with lower risk of osteoporosis until it reached around four. Increasing the social support network size beyond four, in contrast, was associated with a higher risk of osteoporosis. This association was contingent on the average intimacy level of the social network. At the highest average intimacy level (“extremely close”), increasing the number of social support network members from one to six was associated with linear decrease in the predicted probability of osteoporosis from 45% to 30%. However, at the lowest average intimacy level (“not very close”), the predicted probability of osteoporosis dramatically increased from 48% to 80% as the size of the social network increased from one to six.ConclusionOur results show that maintaining a large and intimate social support network is associated with a lower risk of osteoporosis among elderly Korean women, while a large but less-intimate social relationship is associated with a higher risk.

“…The major predictor of greater hip fracture risk is low bone mineral density (BMD) in the femoral neck; yet, studies have not found strong associations between low SES and low femoral neck BMD [9,10,11,12,13]. Of the various indicators of adult SES, education level more than income, occupation, or wealth, has shown consistent associations with BMD [14,15,16,17,18].…”

Purpose Bone acquisition in childhood impacts adult bone mass, and can be influenced by childhood socioeconomic conditions. Socioeconomic status is also associated with body weight which affects the load that bone is exposed to in a fall. We hypothesized that socioeconomic advantage in childhood is associated with greater bone strength relative to load in adulthood. Methods Hip dual x-ray absorptiometry scans from 722 participants in the Midlife in the United States Study were used to measure femoral neck size and bone mineral density, and combined with body weight and height to create composite indices of femoral neck strength relative to load in different failure modes: compression, bending, and impact. A childhood socioeconomic advantage score was created for the same participants from parental education, self-rated financial status relative to others, and not being on welfare. Multiple linear regression was used to determine the association of childhood socioeconomic advantage score with femoral neck composite strength indices, stratified by gender and race (white/non-white), and adjusted for study site, age, menopause status in women, education, and current financial advantage. Results Childhood socioeconomic advantage was independently associated with higher indices of all three composite strength indices in white men (adjusted standardized effect sizes, 0.19 to 0.27, all p values <0.01), but not in the other three race/gender groups. Additional adjustment for adult obesity, physical activity in different life stages, smoking, and heavy drinking over the life-course significantly attenuated the associations in white men. Conclusions Socioeconomic disadvantage in childhood is associated with lower hip strength relative to load in white men, and these influences are dampened by healthy lifestyle choices.
