Objective: Previous studies showed an inconsistent association of fruit and vegetable consumption with bone health. We assessed the associations in Chinese adolescents, young and postmenopausal women. Design: A cross-sectional study conducted in China during July 2009 to May 2010. Setting: Bone mineral density (BMD) and content (BMC) at the whole body, lumbar spine and left hip were measured with dual-energy X-ray absorptiometry. Dietary intakes were assessed using an FFQ. All these values were separately standardized into Z-scores in each population subgroup. Subjects: One hundred and ten boys and 112 girls (11-14 years), 371 young women (20-34 years, postpartum within 2 weeks) and 333 postmenopausal women (50-70 years). Results: After adjustment for potential covariates, analysis of covariance showed a significantly positive association between fruit intake and BMD and BMC in all participants combined (P-trend: , 0?001 to 0?002). BMD Z-score increased by 0?25 (or 2?1 % of the mean), 0?22 (3?5 %), 0?23 (3?0 %) and 0?25 (3?5 %), and BMC Z-score increased by 0?33 (5?7 %), 0?25 (5?8 %), 0?34 (5?9 %) and 0?29 (4?7 %), at the total body, lumbar spine, total hip and femoral neck in participants belonging to the top tertile compared with the bottom tertile of fruit intake (all P , 0?05), respectively. There was no significant association between vegetable intake and bone mass at all bone sites studied except for total body BMD (P 5 0?030). Relatively more pronounced effects were observed in boys and postmenopausal women. Conclusion: Our findings add to the existing evidence that fruits and vegetables may have a bone sparing effect.

“…1 Vertebral, hip, and other fragility fractures in women, associated with osteoporosis in later half of life find their foundation in pre-and peri-menopausal period with a variety of factors affecting the bone mineral metabolism. 2 These include nonmodifiable factors like female sex, old age, small thin built, ethnicity and family history of fractures.…”

OsteoporosisCalcaneal QUS BMD a b s t r a c t Osteoporosis is a major public health problem, associated with substantial morbidity and socio-economic burden. An early detection can help in reducing the fracture rates and overall socio-economic burden. The present study was carried out to screen the bone status (osteopenia and osteoporosis) above the age of 35 yrs in the women. A community based cross sectional study was carried out in 158 women by calculating WHO T-scores utilizing calcaneal QUS as diagnostic tool. The prevalence of osteoporosis and osteopenia was found to be 13.3% AE 5.29% and 48.1% AE 7.79% respectively. Statistical association of prevalence of osteopenia and osteoporosis was found to be significant with age group; gravida status; attainment of menopause; body weight and physically active status of the women. The statistical association was not significant in relation to the rank status of their husband, as well as dietary pattern of the women but still it has to be substantiated by conducting larger community based trials in future.The present study found that there was statistically significant relationship between age group and the prevalence of osteopenia and osteoporosis. There was a negative correlation between age of the women and BMD. Besides age, gravida status and menopausal status have negative correlation with BMD while positive correlation with physically active lifestyle. The results were found to be non-significant in relation to rank status of husband and dietary pattern.ª 2012, Armed Forces Medical Services (AFMS). All rights reserved.

“…40,41 For example, although calcium and vitamin D intake have been shown to have the most consistent effect on BMD, evidence suggests that fruit and vegetable intake may also be associated with BMD. [33][34][35] Similarly, several, but not all, studies have suggested that dietary intake, supplementary intake, or plasma levels of antioxidants found in fruits and vegetables, such as vitamins C, E, and A; beta carotene; lutein; and zeaxanthin, may be protective against onset or progression of ARM.…”

OBJECTIVES:To determine whether bone mineral density (BMD) is associated with age-related maculopathy (ARM) risk in older women. DESIGN: Cross-sectional analysis at Year 10 (1997/98) of the Study of Osteoporotic Fractures (SOF). SETTING: Four clinical centers in the United States. PARTICIPANTS: One thousand forty-two randomly sampled SOF participants who attended the Year 10 clinic visit. MEASUREMENTS: ARM status was determined from fundus photographs using a modification of the Wisconsin Age-Related Maculopathy Grading System 6-level severity scale used in the National Health and Nutrition Examination Survey III. Total hip BMD was measured at Year 10 using dual-energy x-ray absorptiometry. Information on potential confounders, including age, reproductive hormone exposures, body mass index, smoking, alcohol consumption, nutrition, education, diabetes mellitus, hypertension, and physical activity, was ascertained with questionnaires. RESULTS: The prevalence of ARM was 50% (46% had early ARM and 4% had late ARM). After potential confounder adjustment, greater BMD was associated with lower odds of ARM (odds ratio (OR) per 1 standard deviation increase in BMD 5 0.82, 95% confidence interval (CI) 5 0.70-0.96). Women in the highest quartile of BMD had lower odds of ARM than those in the lowest quartile (OR 5 0.63, 95% CI 5 0.41-0.97) and those in the lowest three quartiles combined (OR 5 0.66, 95% CI 5 0.48-0.91). CONCLUSION: Higher levels of BMD may be associated with lower risk for ARM. The underlying mechanism is unknown, although BMD may be a marker for lifetime endogenous estrogen exposure. Future studies are needed to replicate these findings and further investigate the nature of the relationship between BMD and ARM. J Am Geriatr Soc 55: 740-746, 2007.
