RESUMO

BACKGROUND: Emerging evidence suggests that poor dietary quality is an important risk factor for disability. However, few studies have compared adherence to dietary patterns with disability and none among Puerto Rican adults. OBJECTIVES: This study was designed to examine relationships between 3 dietary patterns-including Dietary Approaches to Stop Hypertension (DASH), Mediterranean dietary score (MeDS), and Healthy Eating Index (HEI)-2010-and ∼6-y incidence of activities of daily living (ADL) and instrumental activities of daily living (IADL) disability and to assess potential mediation by handgrip strength. METHODS: Data are from the Boston Puerto Rican Health Study, a longitudinal cohort of Puerto Rican adults aged 45-75 y (N = 1502). Adherence to dietary pattern variables were derived from food frequency questionnaire (FFQ) data averaged at baseline and ∼2 y. Handgrip strength was assessed at baseline. Cox proportional hazards models were used to assess longitudinal associations between DASH, MeDS, and HEI-2010 and incident ∼6-y ADL (and subscales) and IADL disability. Mediation by handgrip strength was also tested. RESULTS: Participants with higher adherence DASH had lower risk of ADL, ADL mobility, and ADL manual dexterity disabilities (hazards ratio [HR]: 0.96; 95% confidence interval [CI]: 0.91, 0.98; HR: 0.96; 95% CI: 0.92, 0.99; and HR: 0.95; 95% CI: 0.92, 0.98, respectively). Higher adherence to MeDS was associated with lower risk of ADL and ADL mobility disabilities (HR: 0.89; 95% CI: 0.81, 0.98; HR: 0.90; 95% CI: 0.82, 1.00), and higher adherence to HEI with lower risk of ADL manual dexterity (HR: 0.98; 95% CI: 0.97, 0.99) in fully adjusted models. Only DASH tended to be associated with IADL (HR: 0.97; 95% CI: 0.94, 1.00). Baseline handgrip strength was a mediator between HEI and ADL manual dexterity (23.7% of the indirect effect was explained through handgrip strength). CONCLUSIONS: Higher adherence to a healthy diet pattern may decrease risk of disability and may be an important prevention strategy for ADL and IADL disability associated with aging.

RESUMO

INTRODUCTION: Nutritional management plays a crucial role in treating patients with type 2 diabetes (T2D), working to prevent and control the progression of chronic non-communicable diseases. OBJECTIVES: To evaluate the effects of individualized nutritional interventions on weight, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), fasting blood glucose (FBG), hemoglobin A1c (HbA1c), total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglycerides (TGs), systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR)} over 12 months and subsequently at follow-up (15 months). METHODS: This longitudinal experimental study (without randomization and blinding) enrolled 84 sedentary participants with T2D (both sexes, aged 18-80 years). They were divided into a control group of 40 participants who received only medical consultations, and an intervention group of 44 participants who received the same medical care along with a nutritional assessment. Consultations occurred quarterly from August 2020 to November 2022 (first-twelfth month), with six to nine patients per session. Subsequently, a follow-up was conducted from December 2022 to November 2023, during which the intervention group had only medical care (during the 12th-15th months). Personalized dietary planning was inspired by the Mediterranean/DASH diets adapted to Brazilian foods and socioeconomic cultures. STATISTICAL ANALYSIS: Normal variables were compared between groups for each time point and also within each group across different time points using a two-way ANOVA (repeated measures for intragroup) followed by the Sídák post hoc test. Non-normal variables were compared between groups for each time point using Kruskal-Wallis followed by the Dunn post hoc test, and within each group across different time points using Friedman followed by the Dunn post hoc test. Data with a Gaussian distribution were presented as mean ± standard deviation (SD), and data with a non-Gaussian distribution were presented as median ± interquartile range (IQR). For all cases, α < 0.05 and p < 0.05 were adopted. RESULTS: In the intervention group, significant reductions were observed between the first and twelfth month for all parameters (p < 0.05), (except for TC), along with an increase in HDL-C (p = 0.0105). Conversely, in the control group, there was a significant increase in HbA1c, weight, BMI, FBG, and WHR (p < 0.05) between the first and twelfth months. Regarding the comparison between groups, there was a significant difference for all analyzed parameters (p < 0.05) from the first to the twelfth month. In the follow-up, differences were also observed (p < 0.05), except for BMI (p > 0.05). CONCLUSION: The individualized nutritional intervention improved eating habits, anthropometric, biochemical, and cardiovascular markers in T2D over 12 months, with sustained results during follow-up. The dietary plan inspired by the Mediterranean and DASH diets demonstrated good adaptation to the Brazilian food culture and the patients' socioeconomic contexts. Consistent monitoring and personalized nutritional management are essential for optimizing long-term outcomes. However, more clinical trials are necessary in order to optimize the level of evidence for longitudinal interventions.

RESUMO

BACKGROUND: Increased serum urate (SU) and hyperuricemia (HU) are associated with chronic noncommunicable diseases and mortality. SU concentrations are affected by several factors, including diet, and are expected to rise with age. We investigated whether the Dietary Approaches to Stop Hypertension (DASH) diet alter this trend. OBJECTIVE: The objective was to assess whether adherence to the DASH diet predicts a longitudinal change in SU concentrations and risk of HU in 8 y of follow-up. METHODS: Longitudinal analyses using baseline (2008-2010, aged 35-74 y), second (2012-2014), and third (2016-2018) visits data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The inclusion criteria were having complete food frequency questionnaire (FFQ) and urinary sodium measurement, in addition to having SU measurement at the 1st visit and at least 1 of the 2 follow-up visits. For the HU incidence analyses, participants had also to be free from HU at baseline. The final samples included 12575 individuals for the SU change analyses and 10549 for the HU incidence analyses. Adherence to DASH diet was assessed as continuous value. HU was defined as SU>6.8 mg/dL and/or urate-lowering therapy use. Mixed-effect linear and Poisson regressions (incidence rate ratio [IRR] and 95% confidence interval [CI]) were used in the analyses, adjusted for confounders. RESULTS: The mean age was 51.4 (8.7) y, and 55.4% were females. SU means (standard deviation) were 5.4 (1.4) at 1st visit, 5.2 (1.4) at 2nd visit, and 5.1(1.3) mg/dL at 3rd visit. The HU incidence rate was 8.87 per 1000 person-y. Each additional point in adherence to the DASH diet accelerated SU decline (P< 0.01) and lowered the incidence of HU by 4.3% (IRR: 0.957; 95% CI: 0.938,0.977) in adjusted model. CONCLUSION: The present study findings reinforce the importance of encouraging the DASH diet as a healthy dietary pattern to control and reduce the SU concentrations and risk of HU.

RESUMO

Background: The Disability of the Arm, Shoulder and Hand (DASH) questionnaire assesses the impact of upper extremity disorders on quality of life. However, its use in the Mexican population has not been formally validated. Objective: To conduct a cultural adaptation and validation of the DASH questionnaire to evaluate the perspective of patients with neurogenic disorders of the upper extremity regarding the impact on their quality of life. Method: We performed an adaptation of the Spanish version of the DASH questionnaire to the Mexican vocabulary and applied it to 478 volunteers. Ceiling effect, floor effect, item-total correlation, descriptive statistics of items and total score, internal consistency, precision, cross-sectional and longitudinal validity were estimated by comparing healthy controls and affected individuals with different disability levels. Results: Our DASH questionnaire version was equivalent to those previously approved and showed homogeneity of the items with respect to the total value of the questionnaire (Cronbach's alpha > 0.96). In addition, it showed an accuracy of 7.25 points and the crosssectional and longitudinal validity was documented with significant differences between groups and subgroups with distinct disability levels. Conclusions: The DASH questionnaire can be used with a high level of confidence in the Mexican population.

RESUMO

Preeclampsia (PE) affects up to five times more women with pre-existing diabetes mellitus (PDM) than women without it. The present study aimed to identify the effect of the DASH diet on PE incidence (primary outcome) and blood pressure, glycated haemoglobin (GH), serum lipids, glutathione peroxidase (GP), C-reactive protein (CRP - secondary outcomes) in pregnant with PDM. This randomised, controlled, single-blind trial studied sixty-eight pregnant women with PDM throughout prenatal care until delivery (18 weeks) at a public maternity hospital, Brazil. The standard diet group (SDG) received a diet containing 45-65 % carbohydrates, 15-20 % protein and 25-30 % lipids. The DASH diet group (DDG) received the adapted DASH diet with a similar macronutrient distribution, but with a higher concentration of fibres, unsaturated fats, calcium, magnesium and potassium as well as lower saturated fat. Student's t, Mann-Whitney U and the Chi-square tests were used to compare outcomes. PE incidence was 22⋅9 % in the SDG and 12⋅1 % in the DDG (P = 0⋅25). GP levels significantly increased in the DDG (intra-group analysis; mean difference = 1588 [CI 181, 2994], P = 0⋅03) and tended to be different from the variation in the SDG (mean difference = -29⋅5 [CI -1305; 1⋅365]; v. DDG: 1588 [CI 181; 2994], P = 0⋅09). GH levels decreased significantly and similarly between groups (SDG: -0⋅61 [CI -0⋅26, -0⋅96], P = 0⋅00) v. DDG: -1⋅1 [CI -0⋅57, -1⋅62], P = 0⋅00). There was no evidence of a difference in PE incidence at the end of the intervention between the two diets. The DASH diet seems to favour PE-related biochemical markers.

Introduction: Hypertension is a chronic disease that increases the risk of systemic complications, especially in the cardiovascular system. Sometimes the disease is asymptomatic, delaying its diagnosis, control and increasing the risk of complications. Maintaining healthy habits and lifestyles are the first prevention and treatment strategy for this condition. Objective: Apply a nutritional intervention, based on the implementation of the DASH diet, to improve nutritional status and control blood pressure figures. Methods: Applied research, with a quasi-experimental, descriptive and correlational design consisting of the application of a nutritional intervention based on the DASH diet. The universe was made up of 54 people who attended a nutrition consultation in order to reduce their body weight, the sample was made up of 48 patients. The McNemar test and ANOVA were applied to verify changes in the variables blood pressure, body mass index and waist circumference. Results: At the beginning of the intervention, patients with high normal blood pressure figures (50.00 %), obesity (58.33 %) and very high risk according to waist circumference (66.67 %) predominated. After the intervention, patients with optimal blood pressure (66.67 %), overweight (58.33 %) and very high risk (50.00 %) predominated. Conclusion: The applied nutritional intervention, based on the implementation of the DASH diet, contributed to the improvement of the nutritional status and the control of the BP figures.

RESUMO

Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and perinatal morbimortality. Dietetic, phenotypic, and genotypic factors influencing HDP were analyzed during a nutrigenetic trial in Rio de Janeiro, Brazil (2016-2020). Pregnant women with pregestational diabetes mellitus (n = 70) were randomly assigned to a traditional or DASH diet group. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured during prenatal visits and HDP were diagnosed using international criteria. Phenotypic data were obtained from medical records and personal interviews. Genotyping for FTO and ADRB2 polymorphisms used RT-PCR. Linear mixed-effect models and time-to-event analyses were performed. The variables with significant effect on the risk for progression to HDP were: black skin color (adjusted hazard ratio [aHR] 8.63, p = 0.01), preeclampsia in previous pregnancy (aHR 11.66, p < 0.01), SBP ≥ 114 mmHg in the third trimester (aHR 5.56, p 0.04), DBP ≥ 70 mmHg in the first trimester (aHR 70.15, p = 0.03), mean blood pressure > 100 mmHg (aHR 18.42, p = 0.03), and HbA1c ≥ 6.41% in the third trimester (aHR 4.76, p = 0.03). Dietetic and genotypic features had no significant effect on the outcome, although there was limited statistical power to test both.

RESUMO

BACKGROUND AND AIMS: To evaluate the effect of lifestyle modification by adopting a DASH diet, with and without physical activity guidance, on blood pressure, glycemic control, lipid profile, weight, and body composition in older patients with type 2 diabetes mellitus (T2DM) and hypertension. METHODS AND RESULTS: For this randomized clinical trial, we recruited patients aged 60 years or older with T2DM and uncontrolled hypertension. One group (DASH) received only DASH dietary guidance, while the other group (DASHPED) received dietary guidance and encouragement to walk with a pedometer. Outcomes of interest were (1) blood pressure, (2) physical activity, (3) weight, body mass index (BMI), and body composition, and (4) biochemical variables. Measurements were taken at baseline and 16 weeks after the intervention. We included 35 patients in the analysis. At the end of the study, the DASHPED group had an mean increase in physical activity of 1721 steps/day. Both groups displayed significantly reduced weight, BMI, and waking diastolic pressures on ambulatory blood pressure monitoring after the intervention. A trend of reduced sleeping diastolic pressure was found in the DASHPED group. Changes in weight, BMI, muscle mass, body fat, waist-hip ratio, glycemic control, lipid profile, and insulin sensitivity did not differ between the groups. CONCLUSION: There was no difference in outcomes between the group that only dieted and the group that also performed increased physical activity, despite a significant increase in exercise. This reinforces the importance of dietary changes in immediate blood pressure control.

RESUMO

Improving dietary patterns is a cornerstone of the non-pharmacological management of hypertension. Evidence about the adherence to healthy dietary patterns at the population level is scarce. We aimed to analyze the adherence to the Dietary Approaches to Stop Hypertension (DASH) diet among Mexican men and women by hypertension status. We used data from the 2012 Mexican National Health and Nutrition Survey (n = 2560). Using self-reported diagnosis of hypertension and blood pressure measurements, we identified participants without, with undiagnosed, and diagnosed hypertension. We calculated DASH scores (total and dietary components) based on a single 24-hour recall and analyzed differences in adherence across hypertension status using sex-specific multivariable Poisson regression models. Overall, regardless of hypertension status, adherence to the DASH score was low, with 35% of men and 38% of women with diagnosed hypertension adhering to recommended guidelines; lower adherence was observed in men (21.8%) and women (27.2%) with undiagnosed hypertension, and with no hypertension (26.8% in men, 26.3% in women). In multivariable models for men, the prevalence of adherence to the total DASH diet was 29% lower in undiagnosed adults versus adults without hypertension (RP 0.71; 95%CI 0.50,0.99). Specifically, adherence to fruits, total dairy, and animal protein was lower in undiagnosed men. Among women, the adherence to the DASH diet was similar across hypertension status in multivariable models. Mexican adults had low adherence to DASH, regardless of hypertension status. Strategies to improve adherence to DASH are needed, focusing in patients with hypertension but also as a preventive measure for the population.
