A look through Latin America truck drivers' health, a systematic review and meta-analysis.

Heavy truck drivers represent a social group of great importance to any country's economy. Their professional activity requires a high level of dedication. Due to the irregular hours in their work routine and adopted habits, they mostly predispose them to a diversity of health problems. The purpose of this study is to perform a systematic review and meta-analysis aiming to identify the prevalence of diabetes, hypertension, and obesity in Latin American Truck Drivers. We searched the PubMed, Web of Science, Scopus and LILACS databases, for scientific publications articles, as reported by The PRISMA Statement. From 1,382, 7 studies were included according to the established criteria. The hypertension prevalence found was 34.2%, diabetes was of 9.2% and the highest prevalence found was for overweight and obesity (56%). Meta-analysis presented that drivers have a higher prevalence of overweight or obesity when compared to eutrophic individuals and that drivers with diabetes and hyperglycemia have a lower prevalence. Due to their work activity, their access to the health system is compromised limiting any type of monitoring of their health. This study showed that there is, in Latin America, an investment and assistance gap, both in the health sector and in the research section, for this professional category, which is so important to the economy of these countries. These data should help to identify the difficulties faced by this professional in health assistance, road safety, public safety, leisure and social life. This research also highlighted that they are young and already have the first sign of non-transmissible chronic diseases, which is overweight and obesity.

Prevalência de isquemia miocárdica na cintilografia em mulheres nos períodos pré/pós-menopausa / Prevalence of ischemia on myocardial perfusion scintigraphy of pre-and postmenopausal women

FUNDAMENTO: No período pós-menopausa, a presença dos fatores de risco para doença arterial coronária (DAC) aumentam. Entretanto, não é bem estabelecida a diferença de prevalência de isquemia miocárdica em mulheres pré/pós-menopausa com múltiplos fatores de risco para DAC. OBJETIVO: Comparar a prevalência de isquemia na cintilografia de perfusão miocárdica com sestamibi-99mTc (CPM) em mulheres nos períodos pré/pós-menopausa e avaliar se a menopausa pode ser considerada fator preditor de risco independente para isquemia em mulheres com múltiplos fatores de risco para DAC. MÉTODOS: Analisamos, retrospectivamente, 500 CPM de mulheres pré/pós-menopausa, com múltiplos fatores de risco cardiovascular. A análise estatística foi realizada por teste exato de Fisher e pelas análises univariada e multivariada, sendo considerado significativo o valor de p < 0,05. RESULTADOS: Do total, 55,9% das mulheres estavam no período pós-menopausa, 83,3% eram hipertensas, 28,9% diabéticas, 61,2% dislipidêmicas, 32,1% tabagistas, 25% obesas e 34,3% já apresentavam DAC conhecida. No grupo pós-menopausa, as mulheres eram mais hipertensas, diabéticas e dislipidêmicas, e tiveram menor capacidade funcional no teste ergométrico (p = < 0,005). Não houve diferença estatística significativa na presença de isquemia na CPM entre os grupos pré/pósmenopausa (p = 0,395). A única variável associada à isquemia na CPM foi a presença de DAC prévia (p = 0,004). CONCLUSÃO: Os resultados obtidos sugerem que, em mulheres com múltiplos fatores de risco para DAC, a menopausa não foi fator preditor independente de isquemia na CPM. Essas informações reforçam a ideia de que a investigação de isquemia pela CPM em mulheres com múltiplos fatores de risco para DAC talvez deva iniciar antes da menopausa.

BACKGROUND: In postmenopausal women, the presence of risk factors for coronary artery disease (CAD) increases. However, the difference in prevalence of ischemia between pre- and postmenopausal women with multiple risk factors for CAD has not been well established. OBJECTIVES: To compare the prevalence of ischemia on Tc99m-sestamibi myocardial perfusion scintigraphy (MPS) in pre- and postmenopausal women, and to evaluate whether menopause can be considered an independent risk predictor of ischemia in women with multiple risk factors for CAD. METHODS: This study retrospectively assessed 500 MPS of pre- and postmenopausal women with multiple risk factors for CAD. Statistical analysis was performed by using Fisher exact test and univariate and multivariate analysis, a p value < 0.05 being considered significant. RESULTS: Postmenopausal women represented 55.9% of the sample; 83.3% were hypertensive; 28.9%, diabetic; 32.1%, smokers; 25%, obese; 61.2% had high cholesterol levels; and 34.3% had known CAD. Postmenopausal women were more often hypertensive, diabetic and dyslipidemic, and had lower functional capacity on exercise testing (p = < 0.005). The presence of ischemia on MPS did not significantly differ between the pre- and postmenopausal groups (p = 0.395). The only variable associated with ischemia on MPS was known CAD (p = 0.004). CONCLUSION: The results suggest that, in women with multiple risk factors for CAD, menopause was not an independent predictor of ischemia on MPS. Those data support the idea that the investigation of ischemia via MPS in women with multiple risk factors for CAD should begin prior to menopause.
