The association between secondhand smoke (SHS) exposure and lumbar and femoral neck osteoporosis was assessed in postmenopausal never-smoking Korean women. The presence of family members who actively smoked was associated with femoral neck osteoporosis. The number of cigarettes consumed by cohabitant smokers was positively associated with lumbar and femoral neck osteoporosis. %26lt;br%26gt;This study aimed to assess the association between SHS and postmenopausal osteoporosis. %26lt;br%26gt;Of 2,067 postmenopausal women (age, a parts per thousand yen55 years) participating in the Fourth Korea National Health and Nutrition Examination Survey, 925 never-smokers identified through interviews and urinary cotinine level verification were enrolled. Cross-sectional relationships between self-reported SHS exposure and osteoporosis of the lumbar vertebrae and femoral neck (defined using the World Health Organization T-score criteria) were investigated by bone densitometry. %26lt;br%26gt;Participants having actively smoking family members showed increased adjusted odds ratio (aOR) for femoral neck osteoporosis compared with participants not exposed to SHS (aOR, 3.68; 95 % confidence interval [CI], 1.23-10.92). Participants whose cohabitant smokers consumed any number of cigarettes per day showed increased occurrences for lumbar and femoral neck osteoporosis compared with the nonexposed group. Participants whose cohabitant smokers consumed a parts per thousand yen20 cigarettes/day showed increased aORs for lumbar (aOR, 5.40; 95 % CI, 1.04-28.04) and femoral neck (aOR, 4.35; 95 % CI, 1.07-17.68) osteoporosis compared with participants not exposed to SHS. %26lt;br%26gt;In postmenopausal never-smoking Korean women, exposure to SHS was positively associated with osteoporosis. This finding further emphasizes a need to identify vulnerable groups exposed to SHS to increase bone health.
