AbstractOBJECTIVE: The participation of Puerto Rico in the Latin American Vertebral Osteoporosis Study (LAVOS) has allowed us to study the magnitude of the problem of osteoporosis in the female population residing in San Juan. The objective of LAVOS was to estimate the prevalence of vertebral fractures in Latin American women using a random sample of females selected from cities across five Latin American countries. METHODS: A probability cluster design was employed to select a random sample of households in San Juan, Puerto Rico, in order to interview 400 females aged 50 years and over. A 30-minute face-to-face interview gathered data on demographics, risk factors, and life styles. Data regarding bone mineral densities of the spine and hip by DXA and lateral dorsolumbar X-rays were obtained using international protocols; digital morphometry was used to determine vertebral deformities, with the results being classified according to Eastell criteria. This article summarizes the main findings observed in San Juan, Puerto Rico. RESULTS: Overall weighted prevalence of vertebral fractures was 11.2% (95% CI: 8.5%, 14.7%). Age-specific prevalence of vertebral fractures was as follows: 5.4% (95% CI: 2.7%, 10.7%) in the 50-59 years age group, 8.3% (95% CI: 4.4%, 15.1%) in the 60-69 years group, 16.2% (95% CI: 10.5%, 25.0%) in the 70-79 years group, and 22.4% (95% CI: 13.3%, 35.1%) in participants > or = 80 years. Factors significantly associated with vertebral fractures were being 70-79 years old (adjusted POR70-79 vs. 50-59 = 2.9; 95% CI: 1.1, 7.4), being > or = 80 years old (adjusted POR > or = 80 vs .50-59 = 3.3; 95% CI: 1.2, 9.4), and a T-score
