RESUMEN

The Community Readiness Model (CR) offers a solution to the development of prevention strategies at the community level that makes use of community collaborations and community capacity. CR was administered in the U.S. Virgin Islands on St. Thomas, St. Croix, and St. John. All three islands scored lowest on dimensions of community climate and highest on knowledge of efforts to fight HIV/AIDS. The findings suggest that initial intervention efforts should improve the community climate of HIV/AIDS denial and stigma prior to introducing interventions that address HIV/AIDS risk behaviors. Community collaborators identify the interplay of social, structural, and political-economic factors for effective prevention.

RESUMEN

OBJETIVOS: Determinar la frecuencia del síndrome metabólico (SM) en cuatro subpoblaciones de residentes de las Islas Vírgenes estadounidenses y calcular el riesgo de sufrir SM asociado con una circunferencia abdominal superior a determinados puntos de corte en personas con sobrepeso y obesidad. MÉTODOS: En un estudio realizado entre 1995 y 1999 se obtuvieron las características demográficas, medidas antropométricas, presión arterial y muestras de sangre de miembros de una cohorte poblacional de 893 personas que pertenecían a cuatro subgrupos poblacionales en Saint Croix (la mayor de las Islas Vírgenes estadounidenses) y que nunca habían recibido un diagnóstico de diabetes. Las cuatro subpoblaciones fueron: 1) hispanos de raza blanca; 2) hispanos de raza negra; 3) personas no hispanas de raza negra nacidas en las Islas Vírgenes estadounidenses y 4) personas no hispanas de raza negra nacidas en otras partes del Caribe. A las muestras de sangre en ayunas se les midieron las concentraciones de glucosa, insulina, triglicéridos y colesterol transportado por lipoproteínas de alta densidad (HDLc). Para identificar el SM se aplicaron las pautas generadas por el Panel III en torno al Tratamiento de Adultos, del Programa Educativo Nacional sobre el Colesterol [National Cholesterol Education Program Adult Treatment Panel III]. La resistencia a la insulina se calculó mediante la valoración de un modelo homeostásico (HOMA-IR). RESULTADOS: La prevalencia general de síndrome metabólico en la muestra fue de 20,5% (intervalo de confianza de 95% [IC95%]: 15,3% a 25,7%). Las personas que se habían clasificado a sí mismas como hispanas y de raza negra tuvieron la frecuencia más alta (27,8% (IC95% = 16,3% a 39,3%)) de SM y los puntajes más altos en el HOMA-IR. Después de hacer ajustes en función de los factores asociados con el estilo de vida y el HOMA-IR, la etnia hispana mostró una asociación independiente con un mayor riesgo de tener SM (razón de posibilidades [RP] = 1,82 (IC95%: 1,07 a 3,07)), triglicéridos séricos elevados (RP = 3,66 (IC95% = 2,18 a 6,15)) y concentraciones séricas bajas de HDLc (RP = 1,60 (IC 95% = 1,04 a 2,45))...

RESUMEN

OBJECTIVES. To determine the frequency of the metabolic syndrome (MS) among four subpopulations in the United States Virgin Islands and to estimate the risk for the MS that is associatd with waist circumference cutpoints among overweight and obese individuals. CONCLUSIONS. The frequency of the MS among Caribbean-born persons in the U.S. VirginIslands is comparable to the frequency of the MS among the general population on the mainland of the United States. Among Caribbean-born persons living in the U.S. Virgin Islands, those who are Hispanic blacks may have a greater risk of cardiovascular disease than do other groups (AU)

RESUMEN

OBJECTIVES: To determine the frequency of the metabolic syndrome (MS) among four subpopulations in the United States Virgin Islands and to estimate the risk for the MS that is associated with waist circumference cutpoints among overweight and obese individuals. METHODS: In a study undertaken from 1995 to 1999, data on demographic characteristics, anthropometric measurements, blood pressure measurements, and a blood sample were obtained from a population-based cohort of 893 Caribbean-born persons from four population subgroups who were living on Saint Croix (the largest island of the U.S. Virgin Islands) and who did not have a history of diagnosed diabetes. The four subpopulations were: (1) Hispanic white, (2) Hispanic black, (3) non-Hispanic black born in the U.S. Virgin Islands, and (4) non-Hispanic black born elsewhere in the Caribbean. Fasting blood samples were analyzed for glucose, insulin, triglycerides, and high-density lipoprotein cholesterol (HDL-C). National Cholesterol Education Program Adult Treatment Panel III guidelines were used to identify the MS. Insulin resistance was estimated by the homeostasis model assessment (HOMA-IR) method. RESULTS: The overall prevalence of the MS in the sample was 20.5% (95% confidence interval (CI) = 15.3%-25.7%). Persons who had classified themselves as both Hispanic and black had the highest frequency (27.8% (95% CI = 16.3%-39.3%)) of the MS and the highest HOMA-IR scores. After controlling for lifestyle factors and HOMA-IR, Hispanic ethnicity was independently associated with an increased risk of having the MS (odds ratio (OR) = 1.82, (95% CI = 1.07-3.07)), high triglycerides (OR = 3.66 (95% CI = 2.18-6.15)), and low HDL-C (OR = 1.60 (95% CI = 1.04-2.45)). A waist circumference of > 88 cm was associated with an increased risk of metabolic abnormalities among overweight and obese women. CONCLUSIONS: The frequency of the MS among Caribbean-born persons in the U. S. Virgin Islands is comparable to the frequency of the MS among the general population on the mainland of the United States. Among Caribbean-born persons living in the U.S. Virgin Islands, those who are Hispanic blacks may have a greater risk of cardiovascular disease than do other groups.

RESUMEN

The objective of this study was to determine whether acculturation and psychosocial stress exert differential effects on body fat distribution and insulin resistance among native-born African Americans and African-Caribbean immigrants living in the US Virgin Islands (USVI). Data collected from a non-diabetic sample of 183 USVI-born African Americans and 296 African-Caribbean immigrants age > 20 on the island of St. Croix, USVI were studied. Information on demographic characteristics, acculturation and psychosocial stress was collected by questionnaire. Anthropometric measurements were taken, and serum glucose and insulin were measured from fasting blood samples. Insulin resistance was estimated by the homeostasis model assessment (HOMA) method. The results showed that in multivariate regression analyses, controlling for age, education, gender, BMI, waist circumference, family history of diabetes, smoking and alcohol consumption, acculturation was independently related to logarithm of HOMA (InHOMA) scores among USVI-born African Americans, but not among African-Caribbean immigrants. In contrast, among USVI-born African Americans psychosocial stress was not significantly related to InHOMA, while among African-Caribbean immigrants psychosocial stress was independently related to InHOMA in models that included BMI, but not in those which included waist circumference. This study suggests that acculturation and psychosocial stress may have a differential effect on body fat distribution and insulin resistance among native-born and immigrant blacks living in the US Virgin Islands.
