Association Between Social Support and Bone Health Outcomes: a Systematic Review

BackgroundBone loss is a major public health concern with large proportions of older women experiencing osteoporotic fractures. Previous research has established a relationship between psychosocial stressors and fractures. However, few studies have investigated bone loss as an intermediary in this relationship. This study investigates whether social stress is associated with bone loss during a 6-year period in postmenopausal women.MethodsData from 11 020 postmenopausal women from the USA was used to examine self-reported psychosocial stress in relation to change in bone mineral density (BMD) measured at the femoral neck, lumbar spine and total hip. Linear regression models were used to examine associations between social measures of psychosocial stress (social strain, social functioning and social support) and per cent change in BMD over 6 years.ResultsHigh social stress was associated with decreased BMD over 6 years. After adjustment for confounders, each point higher in social strain was associated with 0.082% greater loss of femoral neck BMD, 0.108% greater loss of total hip BMD and 0.069% greater loss of lumbar spine BMD (p<0.05). Low social functioning and low social support were associated with greater decreases in femoral neck BMD, and low social functioning was associated with greater decreases in total hip BMD.ConclusionThe findings provide evidence for an association between high social stress and greater bone loss over 6 years of follow-up. In agreement with the prior literature, the findings for social strain and social functioning suggest that poor quality of social relationships may be associated with bone loss in postmenopausal women.

BackgroundThe biological consequences of stress from the social environment pattern health outcomes. This study investigated whether social stress is prospectively associated with fracture incidence among racially and ethnically diverse, postmenopausal women.MethodsData from 160 709 postmenopausal women in the Women’s Health Initiative was analysed using Cox proportional hazards regression models to examine prospective associations of social stress with time to total and hip fracture incidence. Self-reported questionnaires measuring social strain, social functioning and social support were used to assess social stress.ResultsAge and race/ethnicity modified associations between social stress and total and hip fractures. HRs for the associations between higher social support (indicating lower social stress) and total fractures among those age 50–59 years were 0.92 (95% CI: 0.90 to 0.94); HR=0.94 (95% CI: 0.93 to 0.95) for those age 60–69 years and HR=0.96 (95% CI: 0.95 to 0.98) for those age 70–79 years. Higher social strain was associated with greater hip fracture incidence among Native American women (HR=1.84, 95% CI: 1.10 to 3.10), Asian women (HR=1.37, 95% CI: 1.01 to 1.86) and white women (HR=1.04, 95% CI: 1.01 to 1.08).ConclusionIdentifying population patterns of fracture incidence as biological expressions of social environments reveals how race/ethnic specific social environmental factors influence disparities in fractures.
