[Assessment of competencies of community health workers for epidemiological data collection]. / Avaliação de competências de Agentes Comunitários de Saúde para coleta de dados epidemiológicos.

The scope of this study was to assess competencies in terms of reading, comprehension and problem-solving using educational material created for epidemiological research on people with disabilities. A form with twenty multiple-choice questions was prepared and distributed to a sample of 348 community health workers (CHWs) in the State of Paraíba. The socioeconomic profile revealed that, within the sample, most of these CHWs are female, between 30-49 years of age, married or in a stable relationship, with two children and have graduated from high school. Over 98% of CHWs are government employees and more than half have been working for more than eight years in the same community, predominantly in the urban area. The score for overall performance evaluation ranged from 33 to 60 points, with the mean score of 53.44 ± 4.88 points. This means that the CHWs were able to resolve over 65% of the questions properly. The overall performance was positively correlated with education and negatively with age, having children and the time taken to complete high school education. The overall results indicate the increasing professionalization and education of the CHWs and their potential role as collaborators in basic scientific research to make generalizations about public health.

[Could endogamy explain the higher prevalence of disabilities in the population of the Brazilian Northeast?]. / A endogamia explicaria a elevada prevalência de deficiências em populações do Nordeste brasileiro?

Despite conceptual inaccuracies and methods of measurement, the WHO estimates that about 10% of the world population has some form of disability. In order to investigate the prevalence and etiology of disabilities and to evaluate if they could be associated with inbreeding, a cross-sectional epidemiological study was conducted using the informant method in five communities of the state Rio Grande do Norte in the Brazilian Northeast, in which consanguineous marriages frequencies varied between 9 and 32%. The average prevalence of disabilities in the five sampled communities was 4.53%, obtained by interviews that involved 37.87% of a population of 39,054 inhabitants. On average, 25% of consanguineous and 12% of non-consanguineous couples had one or more children with disabilities. The increased rate of individuals with disabilities in the Brazilian Northeast could be associated with the maintenance of the tradition of consanguineous marriages in these populations and some of these disabilities may be caused by genetic disorders.

Effect of the yellow passion fruit peel flour (Passiflora edulis f. flavicarpa deg.) in insulin sensitivity in type 2 diabetes mellitus patients.

BACKGROUND: A study with the yellow passion fruit peel flour showed positive action in blood glucose control as therapies' adjuvant in patients with type 2 diabetes mellitus. Therefore, we evaluated its effect on insulin sensitivity since there is a quest for studies that focus at better understanding of insulin resistance aspects in diabetic patients. Furthermore its relationship with chronic complications can also give good prospects for alternative treatments. METHODS: A total of 43 type 2 diabetes volunteers (28 females and 15 males) ingested 30 g/day of the yellow passion fruit peel flour for two months. The levels of blood glucose and fasting insulin, HOMA index and glycated hemoglobin were measured for each patient before and after dietary supplementation. RESULTS: There was a significant difference in the fasting blood glucose values (P = 0.000) and glycated hemoglobin (P = 0.032) after supplementation. It was also seen a reduction in HOMA IR (P = 0.005) in the supplemented group, however it was not observed changes in insulin values for females. HOMA beta (P = 0.000) showed significant increase in its values for the studied group. CONCLUSIONS: The supplementation used decreased insulin resistance in type 2 diabetic patients, suggesting a positive action in blood glucose control as adjuvant therapy in conventional treatments.
