ABSTRACT This 1988 study reports the point and lifetime prevalence of psychiatric disorders, using DSM-III-R criteria, of a sample (approximately 25%) of adult members of an Indian village previously studied in 1969. The basic instrument was the Schedule for Affective Disorders and Schizophrenia, augmented by available medical information and administered by experienced psychiatrists. Subjects were interviewed and results were weighed for the age- and sex-distributed population. The results indicated a high point prevalence of alcohol dependence (32.8%), with a lifetime prevalence of 72.8%, among males. The lifetime prevalence of affective disorders among women was also high (36.8%), but less so among men (19.3%). When compared with the DSM-III-R diagnoses of the 1969 study, the point prevalence rates of alcohol dependence and abuse disorders fell from 39% to 21%. Also, fewer subjects were judged to be psychiatrically impaired. Even though the prevalence of psychiatric disorders was lower in the current study, the rates for alcohol disorders and affective disorders were still far higher than those reported in Epidemiologic Catchment Area studies. Alcohol dependence (especially among young men) and affective disorder (among women) were major problems.

    ABSTRACT: This study mainly addresses the interface between alcoholism and violence in Brazilian indigenous people. Principal epidemiological studies on alcoholism are described and analyzed. This analysis demonstrates that, in our country, studies on this matter are rare, with the need to carry out more studies so to improve our knowledge on the extension of this problem, acknowledging the specific cultural characteristics of each ethnic group. It indicates the importance of understanding the peculiar significance of the process of alcoholization, making it possible to under-take preventive actions and effective interventions. It concludes the need to urgently overcome the current situation, proposing a close collaboration among community leaders, government and non-government assistance organizations and the academic community to engage efforts in mobilizing and organizing competent personnel.

    ABSTRACT: Substance abuse and obesity are health disparities that may afflict Native Americans more than some other ethnic groups. One theoretical assumption concerning Native people is that the long history of dependence on foraging and subsistence agriculture may have led to selective enrichment of traits that improve genetic fitness, so called 'thrifty' or 'fat sparing' genes. We have speculated that this same selective pressure may have enriched for genetic variants that increase the risk for consumption of alcohol and drugs of abuse. Here, we report the results of a genome scan that compared findings for two consumption phenotypes: 'any drug dependence and/or regular tobacco use' and body mass index (BMI) in southwest California (SWC) Indian families. Variance component analyses from SOLAR were used to generate log of the odds ratio (LOD) scores. Evidence for linkage was found on chromosome 6 for both the 'any drug' (LOD score = 3.3) and BMI (LOD score = 2.3) phenotypes. Bivariate analyses of the two phenotypes revealed a combined LOD score of 4.1 at that location. Additional loci on chromosomes 6, 15, 16 and 21 were found for the 'any drug' phenotype, and on chromosomes 8, 16 and 18 for BMI (LOD scores ranged between 1.2 and 2.3). These results provide suggestive evidence for linkage for substance abuse and BMI in this Mission Indian population and, furthermore, provide preliminary data suggesting that 'consumption phenotypes' may share some genetic determinants.

    ABSTRACT: RESUMO: Este estudo aborda centralmente a relação entre alcoolismo e violência em etnias indígenas do Brasil. São descritos e analisados os principais estudos epidemiológicos sobre alcoolismo realizados no país, constatando-se a escassez e também a necessidade imperativa de mais pesquisas, que permitam um melhor dimensionamento do pro- blema e uma maior visibilidade da caracterização das especificidades culturais de cada etnia. Aponta-se a importância do entendimento do significado peculiar do processo de alcoolização, para que sejam possíveis abordagens preventivas e intervenções efetivas. Conclui-se pela urgência da superação do quadro encontrado, postulando-se uma íntima cola- boração entre líderes comunitários e esforços conjugados para a mobilização e organização de quadros funcionais competentes das entidades assistenciais, governamentais e não-governamentais, e da comunidade acadêmica. PALAVRAS-CHAVE: alcoolismo; violência; indígenas brasileiros; etnopsicologia.
