The prevalence of diabetes in Brazil is comparable with that of more developed countries, where it is considered a major health problem.

The authors postulated that as Mexican Americans became more affluent and/or acculturated to "mainstream" United States life-style they would progressively lose their "obesity-related" pattern of cardiovascular risk factors which were defined as: obesity, diabetes, hypertriglyceridemia and low levels of high density lipoprotein cholesterol. This hypothesis was tested in 1979-1982 in the San Antonio Heart Study, a population-based study on 1,288 Mexican Americans and 929 Anglos living in three San Antonio neighborhoods: a low-income barrio, a middle-income transitional neighborhood, and a high-income suburb. The study population comprised 25-65-year-old men and nonpregnant women. In Mexican American women, all of the "obesity-related" risk factors fell sharply with rising socioeconomic status. In Mexican American men, by contrast, diabetes was the only "obesity-related" risk factor which fell with rising socioeconomic status. Moreover, it fell less steeply, there being an approximately twofold difference in diabetes prevalence between the barrio and the suburbs in men compared to a fourfold difference in women. Also, total and low density lipoprotein cholesterol rose with rising socioeconomic status in Mexican American men, but not in Mexican American women. "Obesity-related" risk factors were generally higher in Mexican Americans of both sexes than in their Anglo neighbors who were of similar socioeconomic status. These results suggest that cultural factors exert a stronger influence on diabetes and cardiovascular risk factors in Mexican Americans than do purely socioeconomic factors.

Diabetes treatment leads to elevated costs both to Brazilian Public Health Care System and society. Costs increased along with duration of disease, level of care and presence of chronic complications, which suggested a need to reallocate health resources focusing on primary prevention of diabetes and its complications.

Prevalence of type 2 diabetes mellitus has increased rapidly and is expected to increase even further. In Latin America countries there is an upward trend among the younger age groups, with a major negative impact on the quality of life and burden of the disease for the health care system. Increasing rates of overweight and obesity associated with lifestyle changes and aging of the population are the main contributing factors to the increasing prevalence of type 2 diabetes. Dietary shifts in the Brazilian population (low frequency of fiber-rich foods and heavy consumption of saturated fatty acids and sugars) and sedentary lifestyle are the main risk factors for obesity, type 2 diabetes, and other chronic diseases. Diabetes prevention programs are being promoted in several countries with results showing improvement in quality of life.

Resumo ObjetivoAvaliar como o desenvolvimento de hábitos bucais deletérios e os problemas de fala afetam a oclusão dentária em pré-escolares. Métodos Foi constituída a amostra probabilística por 2.139 crianças de ambos os sexos, na faixa etária de 3 a 5 anos, matriculadas em instituições públicas ou privadas do Município de Bauru, SP, Brasil. Foi desenvolvido estudo transversal em duas etapas: exame de oclusão e questionário socioeconômico. A classificação de Angle foi adotada para avaliação de aspectos morfológicos da oclusão, observando-se também trespasse horizontal e vertical, espaçamento/apinhamento, mordida aberta anterior, mordida cruzada total, mordida cruzada anterior e mordida cruzada posterior uni ou bilateral. Uma subamostra de 618 crianças apresentou resposta ao questionário sobre hábitos bucais, saúde infantil e informações sobre condições socioeconômicas. Resultados A prevalência de má oclusão foi de 51,3% para o sexo masculino e 56,9% para o sexo feminino, sem variação quanto ao sexo. A maior prevalência de má oclusão foi verificada no grupo etário de três anos, decrescendo significantemente com a idade (p<0,05). Conclusões Entre os fatores ambientais estudados, o hábito de sucção de chupeta foi o mais importante na associação com má oclusão (OR=5,46), seguido da sucção digital (OR=1,54). Dificuldades na fala não apresentaram relação com a má oclusão. Additionally, overjet, overbite, crowding, anterior open bite, posterior Abstract

OBJECTIVE:To compare the effectiveness of individual and group strategies in a diabetes education program. METHODS:A total of 104 type-2 diabetes outpatients enrolled in an education program of a teaching hospital in Belo Horizonte, Southeastern Brazil, were randomly selected and assigned to two different education strategies: group education (54 subjects) and individual education (50 subjects). Group education comprised three monthly sessions, which involved play and interactive dynamics. In parallel, a second group received individual education. Subjects were follow up for six months during 2006 and they were evaluated using specifi c questionnaires: knowledge of diabetes, psychological attitudes, change in behavior, quality of life. Clinical evaluation was performed at baseline, three and six months of intervention. RESULTS:Mean age was 60.6 years. The results of group and individual education were similar in the assessment tests of attitude, change of behavior and quality of life. A reduction in HbA1c levels was seen in both groups, but a statistically signifi cant difference (p=0.012) was found only in the group education.CONCLUSIONS: Both strategies of diabetes education were effective, however, group education was more effective than individual education for blood glucose control.

Middle-income countries are facing a growing challenge of adequate health care provision for people with multimorbidity. The objectives of this study were to explore the distribution of multimorbidity and to identify patterns of multimorbidity in the Brazilian general adult population. Data from 60202 adults, aged ≥18 years that completed the individual questionnaire of the National Health Survey 2013 (Portuguese: “Pesquisa Nacional de Saúde”–“PNS”) was used. We defined multimorbidity as the presence of two or more chronic conditions, including self-reported diagnoses and responses to the 9-item Patient Health Questionnaire for depression. Multivariate Poisson regression analyses were used to explore relationship between multimorbidity and demographic factors. Exploratory tetrachoric factor analysis was performed to identify multimorbidity patterns. 24.2% (95% CI 23.5–24.9) of the study population were multimorbid, with prevalence rate ratios being significantly higher in women, older people and those with lowest educational level. Multimorbidity occurred earlier in women than in men, with half of the women and men aged 55–59 years and 65–69 years, respectively, were multimorbid. The absolute number of people with multimorbidity was approximately 2.5-fold higher in people younger than 65 years than older counterparts (9920 vs 3945). Prevalence rate ratios of any mental health disorder significantly increased with the number of physical conditions. 46.7% of the persons were assigned to at least one of three identified patterns of multimorbidity, including: “cardio-metabolic”, “musculoskeletal-mental” and “respiratory” disorders. Multimorbidity in Brazil is as common as in more affluent countries. Women in Brazil develop diseases at younger ages than men. Our findings can inform a national action plan to prevent multimorbidity, reduce its burden and align health-care services more closely with patients’ needs.
