Lipid abnormalities and subclinical systemic inflammation are associated with atherosclerosis and are used as markers of cardiovascular risk. Studies have suggested a possible beneficial effect of dairy products on cardiovascular health, but the results in lipid and inflammatory markers are still controversial. This study aimed to assess the association between consumption of dairy products and their different subgroups and C-reactive protein (CRP), LDL-cholesterol (LDL-C), and triglyceride/HDL-cholesterol ratio (TG/HDL-C) in participants in the Longitudinal Study of Adult Health (ELSA-Brasil) (n = 9,372). Consumption of dairy products was assessed via a validated food frequency questionnaire and expressed as servings/day. Total consumption of dairy products was described in four categories (≤ 1 serving/day to > 4 servings/day). The associations were estimated via odds ratios (OR), using the group with the lowest consumption (≤ 1 serving/day) as the reference. The lowest ORs for TG/HDL-C in the multivariate model (0.70; 95%CI: 0.55-0.90 in men; and 0.55; 95%CI: 0.43-0.70 in women) were found in the group that consumed > 4 servings day of dairy products. These results were supported by the inverse associations between different subgroups of dairy products and the TG/HDL-C ratio. No association was found between consumption of dairy products and their subgroups and LDL-C and CRP. The results suggest a possible beneficial effect of dairy products on lipid profile, but longitudinal and intervention studies are needed to elucidate the effect mechanisms of different types of dairy products.

This study aimed to investigate factors associated with orthostatic hypotension in 14,833 individuals 35-74 years of age. This was a cross-sectional study of baseline data (2008-2010) from the Longitudinal Study of Adult Health (ELSA-Brasil). Postural testing was performed after 20 minutes resting in supine position and active adoption of orthostatic posture. Blood pressure was measured in supine position and at 3 minutes in orthostatic position with an oscillometer (HEM 705 CP, Omron, São Paulo, Brazil). Orthostatic hypotension was defined as a drop of ≥ 20mmHg in systolic blood pressure and/or a drop of ≥ 10mmHg in diastolic blood pressure. The target covariates were sex, age bracket, race/color, schooling, nutritional status, waist circumference, alteration in the ankle-brachial index, pulse wave velocity, systolic and diastolic blood pressure, hypertension, diabetes, use of antihypertensives, cholesterol, triglycerides, Chagas disease serology, symptoms, and heart rate variation in the postural test, self-reported heart disease, acute myocardial infarction (AMI)/revascularization, and stroke. Orthostatic hypotension was significantly associated with higher age bracket, OR = 1.83 (95%CI: 1.14-2.95); alteration in the ankle-brachial index, OR = 2.8 (95%CI: 1.13-6.88); AMI/revascularization, OR = 1.70 (95%CI: 1.01-2.87); report of heart disease, OR = 3.03 (95%CI: 1.71-5.36); increased systolic blood pressure, OR = 1.012 (95%CI: 1.006-1.019); positive Chagas disease serology, OR = 2.29 (95%CI: 1.23-4.27); and occurrence of symptoms with postural change, OR = 20.81 (95%CI: 14.81-29.24). Presence of orthostatic hypotension can be a warning sign for cardiovascular disorders and thus a useful tool for screening and prevention.

This study aimed to identify sociodemographic factors associated with high estimated sodium/potassium ratio. A total of 15,105 participants were assessed, from 35 to 74 years of age, from a cohort of public employees (ELSA-Brazil). Socioeconomic data were collected with a questionnaire, and 12-hour nighttime urine samples were collected to estimate sodium and potassium intake. Sodium/potassium ratio was calculated in mmol/L and divided into tertiles: 1st tertile, corresponding to "low"; 2nd tertile for "medium"; and 3rd tertile for "high" sodium/potassium ratio. The proportions and means were compared according to the classification of tertiles in the sodium/potassium ratio, using chi-square test and analysis of variance (ANOVA). Crude and adjusted multinomial logistic regression models were tested, with the 1st tertile as the reference. Factors associated with sodium/potassium ratio were: male sex (OR = 1.78; 95%CI: 1.60-1.98); age 35 to 44 years (OR = 1.71; 95%CI: 1.33-2.19); incomplete elementary schooling (OR = 2.38; 95%CI: 1.78-3.18); and lower income (OR = 1.47; 95%CI: 1.26-1.73). Men, younger individuals, and those with less schooling and income showed higher mean sodium/potassium ratio.

The study aimed to identify the simultaneous occurrence of cardiovascular risk factors in children 7 to 10 years of age in Vitória, Espírito Santo State, Brazil, and investigate associated socioeconomic variables. In a sample of 1,282 children, anthropometric data were obtained and blood pressure was measured with an automatic device. Socioeconomic, nutritional, and physical activity data were obtained with a questionnaire. To evaluate the simultaneous occurrence of cardiovascular risk factors, an index was developed including overweight, high blood pressure, poor eating, and sedentary leisure > 4 hours/day. The simultaneous presence of four cardiovascular risk factors was defined as high risk. Socioeconomic status and maternal schooling were included in the logistic regression model. Some 34% of the children presented two cardiovascular risk factors, 20% three factors, and 6.4% four cardiovascular risk factors. Maternal schooling remained associated with high cardiovascular risk (OR: 7.36, 95%CI: 2.09-25.97) and medium risk (OR: 2.57, 95%CI: 1.58-4.20). Low maternal schooling was the most important factor associated with cardiovascular risk.
