The intervention resulted in decreased A1C levels and increased diabetes knowledge, suggesting that using promotoras as part of an interdisciplinary team can result in positive outcomes for Mexican Americans who have type 2 diabetes. Clinical implications and recommendations for future research are suggested.

Using data from the current National Health and Nutrition Examination Survey (1999-2000), the authors assessed whether Helicobacter pylori infection is associated with iron deficiency and iron-deficiency anemia (IDA) in the United States. Iron deficiency was defined as at least two abnormal results out of three biomarkers of iron stores. IDA was defined as a low hemoglobin level in the presence of iron deficiency. H. pylori infection was measured by serology. Complex survey estimators were used in the analysis. For 7,462 survey participants aged >or=3 years, H. pylori infection was associated with decreased serum ferritin levels (percent change = -13.9%, 95% confidence interval (CI): -19.5, -8.0) but not with levels of free erythrocyte protoporphyrin, transferrin saturation, or hemoglobin (percent change = 1.5%, -2.8%, and -1.1%, respectively). Multinomial logistic regression analyses indicated that H. pylori infection was associated with the prevalence of IDA (prevalence odds ratio (POR) = 2.6, 95% CI: 1.5, 4.6) and, to a lesser degree, other types of anemia (POR = 1.3, 95% CI: 1.0, 1.7). H. pylori infection was associated with a 40% increase in the prevalence of iron deficiency (POR = 1.4, 95% CI: 0.9, 2.0) after controlling for relevant covariates. In the United States, H. pylori infection was associated with iron deficiency/IDA regardless of the presence or absence of peptic ulcer disease.

BACKGROUND Considerable efforts have been undertaken in the United States to reduce cervical cancer incidence and mortality by increasing screening; however, disparities in screening rates continue to exist among certain racial and ethnic minority groups. The objective of the current study was to determine the effectiveness of a lay health worker-delivered intervention—AMIGAS (Ayudando a las Mujeres con Informacion, Guia, y Amor para su Salud [helping women with information, guidance, and love for their health])—to increase Papanicolaou (Pap) test screening among 3 populations of women of Mexican origin. METHODS Six hundred thirteen women of Mexican origin in 3 treatment sites were randomized among 4 study arms: the full AMIGAS program with a video and a flip chart (n = 151), the AMIGAS program without the video (n = 154), the AMIGAS program without the flip chart (n = 155), and a usual care control group (n = 153). Six months after enrollment, women were surveyed and reported whether or not they had been screened. RESULTS Women in any of the intervention arms were statistically significantly more likely to report being screened than those in the usual care group in both an intent-to-treat analysis and a per-protocol analysis. In the intent-to-treat analysis, 25% of women in the control group and 52% in the full AMIGAS program group reported having had Pap tests (P < .001); in the per-protocol analysis, the percentages were 29% and 62%, respectively (P < .001). CONCLUSIONS AMIGAS was effective in increasing Pap test screening among women of Mexican descent when used in a 1-to-1 setting. Future research should compare the 1-on-1 intervention with the group-based intervention.

The objectives of this study were: 1) to evaluate the acceptance, effectiveness, and sustainability of a promotora (community health worker) pilot program to improve hypertension control among medically underserved Mexican Americans of the El Paso, Texas area, and 2) to demonstrate improvements in clinical measures of blood pressure, BMI and waist circumference, self-reported behaviors and changes in attitudes and beliefs about blood pressure among Mexican American hypertensives. Participants were eligible if they had been diagnosed with hypertension and if they were willing to be randomized as either participants in the intervention or as controls. A total of 58 participants enrolled in the intervention group and 40 participants served as controls. This was a 9-week promotora intervention. Health behavior constructs and clinical data were measured pre-post intervention. Perceived benefits, and two heart-healthy behaviors (salt and sodium, and cholesterol and fat) were shown to be statistically significantly different between the intervention and control groups.

Pharmacist interventions under a CDTA resulted in significant improvements in glucose and HbA(1c) levels in patients with DM. Postintervention costs for inpatient hospitalization and ED services were significantly less than preintervention costs when DM was a primary or secondary diagnosis for the admission.

A wide range of CAM use was documented in this study. Our results indicate that Hispanics in this area use CAM at a higher rate than national trends. Many of these therapies can adversely affect a variety of disease states and drug therapies.

In this double-blind randomized trial, the first among non-iron-deficient, asymptomatic H pylori-infected children living in the contiguous United States, we found no effect of H pylori eradication regarding changes in iron stores. However, those who had their infection eradicated at follow-up had a significantly larger increase in serum ferritin from baseline.
