Abstract
Objectives
To assess the relationship between sugar-sweetened beverages (SSBs) and bone mineral density (BMD) in Puerto Rican adults living in Boston.
Methods
Data were from the Boston Puerto Rican Health Study and the Boston Puerto Rican Osteoporosis Study. SAS (version 9.4) was used to conduct general linear model analyses assessing bone mineral density as an outcome in relation to all other relevant covariates. Dietary data including sugar-sweetened beverage (SSB) intake was assessed by an FFQ that was validated for this population. We defined SSB as any sweetened drinks, including soft drinks, fruit drinks and nectars, apple juice and 100% juice blends, sweetened tea, energy drinks, coffee drinks, and Malta. Bone mineral density was determined by dual-energy x-ray absorptiometry (DXA) scan.
Results
The mean intake of SSB was 10.7 ± 11 ounces per day, while mean total energy was 1876 ± 843 kcal per day. A majority of the population (62.3%) were post-menopausal women. At the femoral neck, 39.7% had osteopenia and 4.4% had osteoporosis; and at the spine (L2-L4), 30.4% had osteopenia and 8% had osteoporosis. BMD of the femoral neck was significantly associated with SSB intake, and remained significantly associated across all models after adjusting for age, estrogenic status (men, pre-menopausal women or post-menopausal and using estrogen, and post-menopausal women without estrogen), population admixture, BMI, height, total energy, season of bone measurement, alcohol use, smoking status, education, physical activity score, dietary calcium, calcium supplement use, and 25(OH)D (serum) (β ± SE = −0.001 ± 0.001, P = 0.03). Other bone sites did not reach significance.
Conclusions
Intake of SSBs was significantly related to lower femoral neck BMD, and although not significant, was consistently negatively associated with other bone sites. Reduction in SSB intake may decrease risk of osteoporosis in this population.
