RESUMEN
Public health training centers were established to enhance competencies in skills required to meet 21st-century public health challenges. In 2011, the Puerto Rico-Florida Public Health Training Center conducted surveys to assess the training needs of two populations of public health workers serving Hispanic communities: Florida Department of Health employees and workers at the regional and central offices of the Puerto Rico Department of Health. The two surveys were similar, but not identical in content and administration. A 52.6% response rate was achieved in the Commonwealth of Puerto Rico, where limited computer access necessitated use of a pen-and-paper survey. A 20.7% response rate was achieved in Florida, where an online survey was used and incomplete responses were problematic. Puerto Rico respondents (n = 1,414) were similar in age (Mdn age = 48 years) to Hispanic Florida respondents (n = 546, Mdn age =45 years). They also reported higher levels of academic achievement and more years of experience in public health. Nevertheless, self-assessed public health competency scores were in the low- to mid-range for Hispanic respondents in both locales. Although self-assessed training priorities differed, Hispanic employees in both jurisdictions preferred hands-on and face-to-face training to distance learning. Findings indicate a need for training based on adult learning theory, targeted to entry-level employees, and addressing the top five self-assessed training needs, especially health promotion and disease prevention and public health law and policy, which emerged as priority training areas in both survey populations.

OBJECTIVE: Epidemiologic studies have shown that a high calcium intake is related to lower body weight, fat, and serum lipids in obese individuals. However, clinical studies have shown inconclusive results. The present study was conducted to determine if dairy or calcium supplementation alters body composition or serum lipids in Puerto Rican obese adults without dietary energy restriction or exercise. METHODS: A 21-wk randomized clinical trial was conducted in 30 obese adults, aged 21-50 y, with usual calcium intakes <700 mg/d. Subjects were randomly assigned to the following: high dairy (â¼ 1300 mg/d of calcium from dairy products by substituting foods); high calcium (â¼ 1300 mg/d of calcium; â¼ 700 mg/d from diet and 600 mg/d from a supplement); or placebo. Subjects were asked to continue their established dietary intake (except for the high dairy group) and their physical activity during the study. Body weight was measured monthly; body fat, bone, and serum lipids (total cholesterol, high-density lipoprotein, low-density lipoprotein, and triacylglycerol) were measured at baseline and at 21 wk. Pairwise differences in study endpoints among the groups were assessed using ANOVA and post-hoc analysis. RESULTS: Grand mean calcium intake was 1200 ± 370 (median 1187) mg/d in the high dairy group, 1171 ± 265 (median 1165) mg/d in the high calcium group, and 668 ± 273 (median 691) mg/d in the control group, which was significantly lower compared to the two treatment groups (P < 0.001). There were no significant group effects in any of the outcome variables. CONCLUSION: A high dairy or calcium diet alone did not alter body composition or serum lipids profile in a sample of Puerto Rican obese adults.
