MethodIn the experiment， 46% vol Red Star Erguotou （10 mL·kg·d-1） was used to establish the AONFH rat model， and the intervention effect of JPHGP at different doses （2.5， 5.0， 10.0 g·kg-1） was observed. Jiangusheng pill （JGS， 1.53 g·kg-1） was selected as the positive control. After 8 weeks of administration， the bone histomorphometry of the femoral head was analyzed by Micro-CT imaging， and the area of medullary microvessels in the femoral head was detected by ink perfusion. The pathological change was observed by hematoxylin and eosin （HE） staining. The protein expressions of Platelet endothelial cell adhesion molecule-1 （CD31）， VEGF， VEGFR2， PI3K， phosphor-Akt （p-Akt） and phosphatase and Tensin homologue deleted on chromosome 10 （PTEN） in the femoral head were determined by immunohistochemistry and Western blot. ResultCompared with normal group， the model group presented the fracture and thinning of trabeculae in the femoral head， increased empty bone lacunae， and elevated number and diameter of adipocytes （P<0.01）. Micro-CT imaging revealed a decrease in bone mineral density （BMD）， bone volume fraction （BV/TV）， trabecular thickness （Tb.Th） and trabecular number （Tb.N） （P<0.05， P<0.01） while an increase in bone surface-to-volume ratio （BS/BV） and trabecular separation （Tb.Sp） （P<0.01）. The results of ink perfusion showed that the area of medullary microvessels in the femoral head was reduced （P<0.01）. Compared with model group， JPHGP lowered the empty bone lacunae rate as well as the number and diameter of adipocytes in the femoral head of AONFH rats. Micro-CT imaging indicated that JPHGP low-dose group had elevated BV/TV， Tb.Th and Tb.N （P<0.05， P<0.01） while decreased BS/BV （P<0.01）， and there was an upward trend in BMD while a downward trend in Tb.Sp， but without statistical difference. In addition， JPHGP medium- and high-dose groups had a rise in BMD， BV/TV， Tb.Th and Tb.N （P<0.05， P<0.01）， a decrease in BS/BV and Tb.Sp （P<0.05， P<0.01） and enlarged area of medullary microvessels in the femoral head （P<0.05， P<0.01）. The expressions of CD31， VEGF， VEGFR2， PI3K， p-Akt in the model group were lower than those in the normal group （P<0.01）， and after medium and high doses of JPHGP treatment， the expressions of CD31， PI3K and p-Akt in the femoral head of rats were up-regulated （P<0.01） while the protein expression of PTEN was down-regulated （P<0.01）. Moreover， JPHGP up-regulated the expressions of VEGF and VEGFR2 （P<0.05， P<0.01）. ConclusionJPHGP can repair the vascular injury in AONFH， and its mechanism may be related to the activation of VEGF/VEGFR2/PI3K/Akt signaling pathway. This study provides certain scientific basis and reference for the clinical application of JPHGP. ObjecctiveTo observe the repair effect of Jianpi Huogu prescription （JPHGP） on vascular injury in experimental alcohol-induced osteonecrosis of femoral head （AONFH）， and to explore its mechanism based on vascular endothelial growth factor （VEGF）/VEGFR2/phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway.

ObjectiveTo investigate the protective effect of Geju Hugan tablets on the liver of mice with alcohol-induced liver injury， and explore the underlying mechanism based on nuclear factor-κB p65 （NF-κB p65） and B-cell lymphoma-2 （Bcl-2）/Bcl-2-associated X protein （Bax） signaling pathways. MethodAccording to the body weight， 60 SPF-grade male ICR mice were randomized into normal， model， Compound Yiganling tablets （0.16 g·kg-1）， and low-， medium-， and high-dose （0.2， 0.4， 0.8 g·kg-1， respectively） Geju Hugan tablets groups. The drugs were administrated at the corresponding doses by gavage， and the normal and model groups with equal volume of pure water once a day for 28 consecutive days. On day 29， the mice in other groups except the normal group were administrated with liquor （53% Vol） by gavage twice a day at the doses of 20， 10 mL·kg-1 and with the interval of 6 h. Samples were harvested on day 30. The histopathological changes in the liver were observed by hematoxylin-eosin （HE） staining， and the ultrastructural changes in hepatocytes were observed by transmission electron microscopy. The enzyme-linked immunosorbent assay was employed to measure the levels of malonaldehyde （MDA）， reduced glutathione （GSH）， and triglycerides （TG） in the liver tissue and the levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in the serum. Western blotting was employed to determine the protein levels of NF-κB p65， phosphorylated p-inhibitor kappa B alpha （p-IκBα）， Bcl-2， and Bax in the liver tissue. ResultCompared with the normal group， the model group showed increases in the ALT， AST， MDA， and TG levels， a decrease in the GSH level， and increases in the liver injury scores evaluated based on the HE， oil red O， and transmission electron microscopy （P<0.01）. Moreover， the model group showed up-regulated expression of NF-κB， p-IκBα， and Bax （P<0.05， P<0.01） and down-regulated expression of Bcl-2 （P<0.05） in the liver tissue. Compared with the model group， Geju Hugan tablets of all the doses lowered the ALT， AST， MDA， and TG levels and elevated the GSH level （P<0.01）. The liver injury scores assessed based on HE staining and transmission electron microscopy in the medium- and high-dose Geju Hugan tablets groups were lower than those in the model group （P<0.01）. Compared with the model group， medium- and high-dose Geju Hugan tablets down-regulated the protein levels of NF-κB， p-IκBα， and Bax （P<0.01） and all doses of Geju Hugan tablets up-regulated the protein level of Bcl-2 （P<0.01）. ConclusionGeju Hugan tablets protect mice from alcohol-induced liver injury by down-regulating NF-κB signaling pathway to alleviate inflammation in the liver tissue and down-regulating the expression of Bax and up-regulating the expression of Bcl-2 to inhibit hepatocyte apoptosis.

RESUMEN La enfermedad hepática alcohólica tiene un amplio espectro de enfermedades, incluida la hepatitis alcohólica, que en sus formas graves puede conducir al síndrome hepatorrenal. La anemia es común en pacientes alcohólicos, pero una anemia hemolítica asociada con hiperlipidemia e ictericia se reconoce como síndrome de Zieve. Un varón de 42 años con consumo excesivo de alcohol fue admitido por ictericia y dolor abdominal. Durante su evolución presentó azoemia progresiva y anemia hemolítica. Se realizó el diagnóstico de síndrome hepatorrenal asociado a hepatitis alcohólica, así como un síndrome de Zieve. Fue tratado con corticoterapia y la combinación de albúmina y noradrenalina, además del retiro de alcohol, con resultados favorables.

ABSTRACT Alcoholic liver disease has a broad spectrum of diseases, including alcoholic hepatitis, which in its severe forms can lead to hepatorenal syndrome. Anemia is common in alcoholic patients, but a hemolytic anemia in association with hyperlipidemia and jaundice is recognized as Zieve's syndrome. A 42 year old man with heavy alcohol consumption was admitted for jaundice and abdominal pain. During his evolution, he presented progressive azotemia and hemolytic anemia. The diagnosis of hepatorenal syndrome associated with alcoholic hepatitis was made, as well as a Zieve's syndrome. He was treated with corticosteroid therapy and the combination of albumin and norepinephrine, in addition to alcohol withdrawal, with favorable results.

Bone turnover characteristics in patients with alcohol-induced osteonecrosis of the femoral head / 中国组织工程研究

BACKGROUND: The pathological changes of alcohol-induced osteonecrosis of the femoral head (ONFH) are the result of a combination of various factors, and its specific pathogenesis is inconclusive. Related studies have shown abnormal bone metabolism in patients with avascular necrosis of the femoral head. OBJECTIVE: To explore the bone turnover markers in patients with alcohol-induced ONFH and to explore the relationship between different stages of ONFH and bone metabolism. METHODS: This study retrospectively selected 193 male patients with alcohol-induced ONFH (necrosis group), including 35 cases of ARCO stage II, 131 cases of ARCO stage III and 27 cases of ARCO stage IV. Among them, there were 65 cases of a little drinking of alcohol 52 cases of moderate drinking, and 76 cases of heavy drinking. Another 182 healthy males undergoing physical examination with no history of drinking were taken as control group. The bone turnover markers [procollagen type 1 N-terminal propeptide (P1NP), C-terminal cross-linked telopeptides of type 1 collagen (β-CTX), molecular fragment of N-terminal osteocalcin (N-MID) and 25 hydroxyvitamin D (25OHD)] and biochemical indexes were tested and compared between two groups, followed by logistic regression analysis and correlation analysis. The study protocol was performed in line with the relevant ethic requirements of the First Affiliated Hospital of Guangzhou University of Chinese Medicine. All participants in the trial had been fully informed of the trial process. RESULTS AND CONCLUSION: In the necrosis group, P1NP, β-CTX, N-MID, 25OHD, serum calcium, uric acid, alkaline phosphatase, serum phosphorus levels were significantly higher than that of the control group (P < 0.05), and apolipoprotein A1 and high-density lipoprotein levels in the necrosis group were significantly lower than those in the control group (P < 0.05). Compared with patients with low level of alcohol, β-CTX and N-MID levels were significantly reduced in the patients with heavy drinking (P < 0.05). The P1NP level of patients with ARCO stage IV was significantly higher than that of patients with ARCO stage II and III (P < 0.05), and the β-CTX level of patients with ARCO stage IV was significantly higher than that of patients with ARCO stage III (P < 0.05). The correlation analysis results showed that alcohol intake levels were negatively correlated with β-CTX, alkaline phosphatase level was positively correlated with P1NP and β-CTX, and 25OHD was negatively correlated with low-density lipoprotein. Logistic regression analysis results showed that: P1NP (odds ratio=0.984, P=0.004), β-CTX (odds ratio=0.325, P=0.043), and high-density lipoprotein (odds ratio=2.622, P=0.014). To conclude, male patients with alcohol-induced ONFH have active bone formation and bone resorption, and obvious abnormalities in lipid metabolism. The progression of alcohol-induced ONFH can be predicted by these bone turnover markers.

The blood was got from eyeballs and the mice were killed after 8 weeks of ethanol induction. We detected the activity of serum aspartate aminotransferase (AST) in mice of different groups. The pathological changes were detected by HE staining, sirius red staining and periodic acid-Schiff (PAS) staining in the liver of mice. The expression of Gp96 and transforming growth factor βl ( TGF-βl ) were detected by Western blotting. Results Compared with the normal control group, the AST enzyme activity and liver fibrosis increased significantly, glycogen decreased significantly in other three groups (P<0.01). Compared with the saline+alcohol group, the AST enzyme activity and liver fibrosis increased more significantly, glycogen decreased more significantly, Gp96 expression decreased significantly and TGF-βl expression increased significantly in Gp96-sgRNA3+ alcohol group and NF-κB inhibitors PDTC+ alcohol group (P<0.01 or P<0.05). Conclusion The injection of CRISPR expression plasmid Gp96-sgRNA3 by tail vein significantly inhibited the Gp96 expression, promoted the degree of alcoholic liver fibrosis in mice, and NF-κB signaling pathway played a certain role in regulating the expression of Gp96.

Screening of Sera from Patients with Pancreatitis by an Apoptosis Assay of Skin-derived Cells / 대한소화기학회지

BACKGROUND/AIMS: An excessive inflammatory response is typical in acute pancreatitis and a significant cause of early mortality in severe acute pancreatitis. This is believed to be caused by inflammatory molecules or upregulated cytokine levels in the serum of patients. The aim of this study was to identify the serum-mediated apoptosis-inducing effects in acute pancreatitis patients.METHODS: A skin tissue-derived cell line, BJ, was treated for 24 hours with the sera of 22 healthy volunteers (control) and 71 acute pancreatitis patients (22 with gallstone pancreatitis, 16 with alcoholic pancreatitis, and 11 with pancreatitis with other causes) collected at the time of hospital admission (active) and discharge (resolved). Apoptosis was analyzed by flow cytometry.RESULTS: The average percentage of living cells, early apoptotic cells, and late apoptotic cells ranged from 78.8% to 85.0%, 5.5% to 7.3%, and 7.7% to 13.1%, respectively. The number of live cells increased significantly using the serum from the resolved state of gallstone-induced pancreatitis. In addition, the number of early apoptotic cells increased significantly using the serum from the resolved state of pancreatitis with other causes. The number of late apoptotic cells decreased significantly with the serum from the resolved state compared to the active state of gallstone- and alcohol-induced pancreatitis.CONCLUSIONS: Serum samples from patients with pancreatitis induced a change in the apoptosis profiles of skin-derived cells. These results indicate changes in the serum components in patients with acute pancreatitis.

Difference in Cognitive Function by First Onset Age of Alcohol Induced Blackout and Its Duration

OBJECTIVE: Alcohol-induced blackout (blackout) is a typical early symptom of cognitive impairment caused by drinking. However, the first onset age of blackout or the duration after onset of blackout has not been directly compared in previous studies. The purpose of this study was to investigate the differences in cognitive function to the first start age of blackouts and their duration. METHODS: Thirty-one male subjects were included in this study. Their age at the first blackout and the duration after the onset of blackout were investigated. Neuropsychological tests were conducted to determine their attention, memory, and executive function. Subjects were divided into three groups according to their age of the first onset blackout (group O1, 40 years). Subjects were also divided into three groups by duration after the onset of blackout (P1, 30 years). We then examined differences in neurocognitive function among these groups. RESULTS: O1 tended to have a lower memory score than O2 (F = 3.28, p = 0.053). Significant differences were observed in attention and executive function between groups P1 and P3 (Digit Span_backward: F = 6.07, p < 0.05; visual span_forward: F = 4.19, p < 0.05; executive intelligence quotient: F = 3.55, p < 0.05). CONCLUSION: Greater memory impairment was detected in subjects having an earlier age of the first blackout. The longer the duration after the onset of blackout, the more impaired their attention and executive function skills.

Associação da atividade física de lazer com o consumo de bebidas alcoólicas em adultos / Association of physical activity in leisure-time with alcohol consumption in adults

Evidências mostram que atividade física (AF) pode se associar a níveis mais elevados de consumo de bebida alcóolica. Assim, esse estudo teve como objetivo verificar se existe ou não associação do nível de AF de lazer com o consumo de bebida alcóolica entre adultos de ambos os sexos. Dados secun-dários foram coletados do Ministério da Saúde (Vigitel) referente ao inquérito transversal realizado no ano de 2014, na cidade de Curitiba, PR, Brasil. A AF foi a variável de exposição e o consumo de bebida alcoólica a variável de desfecho. Participaram do estudo 1.504 adultos, sendo 557 homens com idade média de 51,7 ±18,6 anos e 947 mulheres com idade média de 55,7 ± 16,9 anos. O nível de AF foi categorizado em inativo e ativo e o consumo de bebida alcóolica em regular e abusivo. Os resultados foram controlados por sexo, idade e escolaridade. Os adultos ativos tiveram risco pelo menos 1,5 vezes maior (Razão de Prevalência (RP)= 1,5; IC95%: 1,2­1,9) para o consumo regular de bebida alcoólica e pelo menos 1,3 vezes maior (RP= 1,3; IC95%: 0,8­2,1) para o consumo abu-sivo, quando comparado aos inativos. Os homens ativos tiveram risco pelo menos 1,7 vezes maior (RP= 1,7; IC95%: 1,2­2,5) para o consumo regular e 2,3 vezes maior (RP= 2,3; IC95%: 0,9­5,7) para o consumo abusivo, enquanto mulheres ativas tiveram risco pelo menos 1,4 vezes maior (RP= 1,4; IC95%: 1,1­1,8) para o consumo regular e 0,9 vezes maior (RP= 0,9; IC95%: 0,6­1,7) para o consumo abusivo. Os resultados apoiam a existência de uma associação positiva incongruente entre o consumo de bebida alcoólica e a prática de AF.

However, recent studies indicated that higher levels of physical activity may be associated with higher levels of alcohol consumption. The objective of this study is to verify the association between physical activity level and abusive alcohol consumption of adults of both sexes. Secondary data were collected from the Ministry of Health/Vigitel/2014. The PA was the exposure variable and alcohol consumption as the outcome variable. Data were collected from the individual behavior analysis of 1,504 Brazilian adults, 557 men with a mean age of 51.7 ± 18.6 years and 947 women with a mean age of 55.7 ± 16.9 years from Curitiba city. Were categorized according the level of PA (inactive and active) and alcohol consumption (regular use and abu-sive use). The results were controlled by gender, age and schooling. Actives had at least 1.5 times higher risk (Prevalence Ratio (PR)= 1.5; 95%CI: 1.2­1.9) for regular consumption of alcoholic beverages and at least 1.3 times higher risk (PR= 1.3; 95%CI: 0.8­2.1) for abusive consumption, when compared to inactives. Active men had at least 1.7 times higher risk (PR= 1.7; 95%CI: 1.2­2.5) for regular consumption and 2.3 times higher risk (PR= 2.3; 95%CI: 0 9­5.7) for abusive consumption, while active women had at least 1.4 times higher risk (PR= 1.4; 95%CI: 1.1­1.8) for regular consumption and 0.9 times higher risk (PR= 0.9; 95%CI: 0.6­1.7) for abusive consumption. For the examined sample, the results provide support for the existence of an incongruent positive association between regular alcohol consumption and PA practice.

Effects of DA-5513 on alcohol metabolism and alcoholic fatty liver in rats / 한국실험동물학회지

Hangover is characterized by a number of unpleasant physical and mental symptoms that occur after heavy alcohol drinking. In addition, consistently excessive alcohol intake is considered as a major reason causes liver disease. The present study investigated the in vivo effects of DA-5513 (Morning care® Kang Hwang) on biological parameters relevant to hangover relief and alcoholic fatty liver. Blood alcohol and acetaldehyde concentrations were determined in rats administered a single dose of alcohol and treated with DA-5513 or commercially available hangover relief beverages (Yeomyung® and Ukon®). The effects of DA-5513 on alcoholic fatty liver were also determined in rats fed alcohol-containing Lieber-DeCarli diets for 4 weeks. Serum liver function markers (aspartate and alanine aminotransferase activities) and serum/liver lipid levels were assessed. Blood alcohol and acetaldehyde concentrations were lower in the groups treated with DA-5513 or Yeomyung®, as compared with control rats. However, Ukon® did not produce any significant effects on these parameters. Treatment with DA-5513 significantly reduced serum aspartate and alanine aminotransferase activities and markedly reduced serum cholesterol and triglyceride levels, as compared with control rats. Histological observations using Oil Red O staining found that DA-5513 delayed the development of alcoholic fatty liver by reversing hepatic fat accumulation. These findings suggest that DA-5513 could have a beneficial effect on alcohol-induced hangovers and has the potential to ameliorate alcoholic fatty liver.

Padrões do consumo de substâncias psicoativas em comunidades indígenas da etnia Karipuna do município do Oiapoque-AP / Patterns of psychoactive substance used in indigenous Karipuna communities in the municipality of Oiapoque-AP

Introdução: a temática de álcool e outras drogas ainda é pouco explorada entre as populações indigenas brasileiras; considerando-se a necessidade de explorar esse problema e a escassez de estudos sobre este fenômeno na região norte do Pais, realizou-se esta pesquisa. Objetivo: identificar os padrões do consumo de substâncias psicoativas na etnia Karipuna do municipio de Oiapoque, estado do Amapá, verificando a associação desses padrões com variáveis sociodemográficas, clínicas e comportamentais da amostra. Método: estudo transversal, realizado em 12 aldeias da etnia Karipuna, localizadas no município de Oiapoque. A amostra constitui-se de 230 individuos predominantemente do sexo masculino (51,3%), faixa etária de 16 a 30 anos (46,5%), católicos (71,1%), com ensino fundamental incompleto (28,3%). Para a coleta de dados foram utilizados o Alcohol Use Disorder Identification Test (AUDIT), a Questão chave (QC) e o Alcohol, Smoking and Substance Involvment Screening Test (ASSIST). Para a análise dos dados realizou se o teste de qui quadrado para verificar a associações entre as variáveis de interesse e o padrão de consumo das substâncias; posteriormente foram selecionadas as variáveis para compor o modelo de regressão logística com prefixação do p-valor de 0,20, obtendo-se daí os valores do Odds Ratio (OR), entre as variáveis selecionadas na regressão logística. Resultados: de acordo com o AUDIT 59,5% dos entrevistados faziam uso de baixo risco, 32,1% uso de risco, 6% uso nocivo e 2,4% apresentavam provável dependência. A prevalência de alteração de pressão arterial entre os entrevistados foi de (19%), diabetes (3,1%), presença de pensamento suicida (13,5%), tentativas de suicidio (9,5%), mais de um terço dos entrevistados (35,6%), referiu manter Relações Sexuais Após Consumo de Álcool (RSACA). Os maiores preditores do uso de risco e nocivo de acordo com o AUDIT foram ser do sexo masculino (OR=2,47), apresentar pensamento suicida (OR=3,02) e manter RSACA (2,21). Os resultados do ASSIST mostraram que 73,4% dos entrevistados faziam uso ocasional de álcool, 26% faziam uso abusivo e 0,6% apresentava possível dependência. Os preditores do uso problemático, segundo o ASSIST, foram: ser do sexo masculino (OR=2,33), apresentar alteração de pressão (OR=4,03) e manter RSACA (OR=2,34). Em relação à Questão-chave, 42,2% dos entrevistados faziam uso de risco mais de 4 vezes ao ano, como principais preditores desse uso: ser estudante (OR=2,99), ter migrado da aldeia de origem (OR=2,22), fazer uso de preservativo (OR=2,62); manter RSACA (OR=1,61). O uso problemático do tabaco foi observado em 16,6% da amostra, os principais preditores desta condição foram: pertencer ao sexo masculino (OR=4,24); ter migrado da aldeia de origem (OR=3,27). Conclusão: as drogas de maior prevalência entre os indigenas da etnia Karipuna são licitas, e seu padrão de uso problemático é maior que o observado entre a população geral. A prática RSACA foi importante preditor do uso problemático e álcool, independentemente do instrumento de rastreio; medidas preventivas devem, pois, ser maximizadas entre esta população. Os dados deste estudo têm potencial para subsidiar a realização de pesquisas futuras nesta área, não só em relação aos povos de etnia Karipuna, mas a outras etnias indigenas da região norte brasileira e do Brasil.

Introduction: Alcohol and other drugs themes are still little explored in Brazilian indigenous population. Considering the need to explore this problem and the scarcity of studies investigating this phenomenon in the northern region of the country, this research was carried out. Objective: To identify patterns of psychoactive substance used in the Karipuna ethnic group of the city of Oiapoque in the state of Amapá verifying the association of these patterns with socio-demographic, clinical and behavioral variables of the sample. Method: This is a cross-sectional study carried out in twelve villages of ethnic Karipuna, located in the municipality of Oiapoque. The sample was 230 individuals predominantly male (51.3%), from 16 to 30 years old (46.5%), Catholic (71.1%), with incomplete elementary school (28.3%). For the data collection, the Alcohol Use Disorder Identification Test (AUDIT), the Key Question (KQ) and the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) were used. The chi-square test was used to analyze the associations between the variables of interest and the pattern of consumption of the substances. Then, the variables were selected to compose the logistic regression model with pre fixation of the p-value of 0.20, obtaining the Odds Ratio (OR) values from this model, among the variables selected in the logistic regression. Results: According to the AUDIT, there were 59.5% of the interviewees who used psychoactive substance at low risk, 32.1% at risk, 6% at a harmful use and 2.4% had a possible dependency The prevalence of altered blood pressure in the interviewees was (19%), diabetes (3.1%), suicidal thoughts (13.5%), suicide attempts (9.5%), more than a third of respondents (35.6%), reported maintaining sexual relationships after alcohol consumption (SRAAC). The highest predictors of risk and harmful use of a psychoactive substance according to the AUDIT were male (OR 2.47), suicidal thoughts (OR=3.02) and SRAAC (2.21). The ASSIST results showed that 73.4% of the interviewees had occasional use of alcohol, 26% had an abusive use of alcohol) and 0.6% had a possible dependency. The predictors of problematic use using ASSIST were: male (OR=2.33), having pressure changes (OR=4.03) and maintain SRAAC (OR 2.34). Regarding the Key Question, there were 42.2% of respondents having a risk of psychoactive substance use in more than 4 times a year, with students as the main predictors of this use (OR 2.99), having migrated from the village of origin (OR=2, 22), using a condom (OR=2.62) and maintaining SRAAC (OR=1.61). The problematic use of tobacco was observed in 16.6% of the sample. The main predictors of this condition were male (OR=4.24) and migrated from the village of origin The drugs with the highest prevalence in the Karipuna ethnic are legal and the pattern of their problematic use is greater than the general population. The SRAAC practice proved to be an important predictor of this problematic use and alcohol regardless of the screening instrument indicating that preventive measures should be maximized in this population. The data from this study has the potential to support future research in this area, involving not only ethnic Karipuna people but also other indigenous ethnic groups from the northern Brazilian region and the rest of Brazil.

Alcohol-related disorders and associated factors in a rural area in Brazil / Transtornos relacionados ao uso de álcool e fatores associados em zona rural do Brasil

ABSTRACT OBJECTIVE To describe the prevalence of alcohol-related disorders and associated factors in an exclusively rural population. METHODS This is a cross-sectional, population-based study of a rural research consortium, conducted in a medium-sized city in Southern Brazil, with adults living in a rural area, using the AUDIT (Alcohol Use Disorders Identification Test). The analysis included the prevalence of alcohol-related disorders and associated factors, such as the sociodemographic, family, and health factors; it was carried out by Poisson regression, in a hierarchical analysis model, with a 95% confidence interval. RESULTS The final sample amounted to 1,519 subjects. The prevalence of alcohol-related disorders (AUDIT ≥ 8) was 8.4% (95%CI 7.0-9.8). Risk factors for alcohol-related disorders were being male (PR = 8.2, 95%CI 4.82-14.16), age group between 18 and 29 years (PR = 3.29, 95%CI 1.80-6.0), and smoking (PR = 1.88, 95%CI 1.03-3.43). The practice of religion (PR = 0.38, 95%CI 0.25-0.58) and education level between nine and 11 years (PR = 0.33, 95%CI 0.16-0.69) were protective factors with statistical significance. Marital status and social status were not associated with the outcome studied. CONCLUSIONS The prevalence of alcohol-related disorders in the rural population is high, but, on average, it is lower than that found in urban populations. Risk and protective factors were similar to those found in previous studies. Men, younger persons, and smokers are at higher risk for alcohol-related disorders. On the other hand, practicing a religion and having a higher education level were protective factors.

RESUMO OBJETIVO Descrever a prevalência de transtornos relacionados ao uso de álcool e fatores associados em uma população exclusivamente rural. MÉTODOS Estudo transversal de base populacional, integrante de um consórcio de pesquisa rural, realizado em cidade de médio porte do Sul do Brasil, com adultos residentes na zona rural, utilizando o AUDIT (Alcohol Use Disorders Identification Test). A análise incluiu a prevalência dos transtornos relacionados ao uso de álcool e fatores associados, como sociodemográficos, familiares e de saúde; foi realizada por regressão de Poisson, em modelo hierarquizado de análise, com intervalo de confiança de 95%. RESULTADOS A amostra final foi de 1.519 indivíduos. A prevalência de transtornos relacionados ao uso de álcool (AUDIT ≥ 8) foi de 8,4% (IC95% 7,0-9,8). Os fatores de risco para transtornos relacionados ao uso de álcool foram sexo masculino (RP = 8,26; IC95% 4,82-14,16), faixa etária entre 18 e 29 anos (RP = 3,29; IC95% 1,80-6,0) e tabagismo (RP = 1,88; IC95% 1,03-3,43). Como fatores de proteção com significância estatística encontramos a prática de religião (RP = 0,38; IC95% 0,25-0,58) e escolaridade entre nove e 11 anos de estudo, (RP = 0,33; IC95% 0,16-0,69). Estado civil e classe social não estiveram associados com o desfecho estudado. CONCLUSÕES A prevalência de transtornos relacionados ao uso de álcool na população rural é alta, porém, em média, mais baixa do que as encontradas em populações urbanas. Os fatores de risco e proteção foram similares aos encontrados em estudos prévios. Os homens, as pessoas mais jovens e os tabagistas têm maior risco para apresentar transtornos relacionados ao uso de álcool. Por outro lado, praticar uma religião e ter maior escolaridade foram fatores de proteção.
