Albert, PhD, CCNS, CCRN,Obesity is a chronic, multifactor disease with sizeable socio sanitary and economic consequences and is an issue in public health, mostly in developing countries. It causes or exacerbates a large number of health problems: diabetes, coronary heart disease, hypertension, and the incidence of certain cancers. It has been linked to a greater risk of cardiovascular mortality, a higher prevalence of psychopathology disorders and social maladjustment with a higher health care cost and shorter life-expectancy. In Spain, nowadays, the prevalence of overweight and obesity is nearly 50% of population. SEEN has developed a Clinical Practice Guide on diagnosis, evaluation and treatment of overweight and obesity in adult people with two sections: 1) Definition and classification of adult obesity, its epidemiology, etiopathogeny, complications, benefits of weight reduction and clinical evaluation of patients with overweight or obesity, and 2) Identification of patients with obesity risk subsidiary to weight reduction treatment, therapy goals and therapeutical strategies available to achieve them indicating as well the degree of recommendation based upon scientific evidence on each aspect. Although obesity is a disease which is supposed to involve not only medical but also political authorities, social agents, educators and food industry among others, SEEN decided to develop this Guide taking into account the evident endocrinological and metabolical aspects of this disorder. The Guide contains scientific evidencebased recommendations intended to help doctors making decisions on diagnose, evaluations and treatment of adult overweight so that a more homogeneous attendance with settled quality can be

Angiotensinogen genotype and blood pressure response in the Dietary Approaches to Stop Hypertension (DASH) study

Objective To determine the relationship between angiotensinogen (ANG) genotype and blood pressure response to the dietary patterns of the Dietary Approaches to Stop Hypertension (DASH) trial. The angiotensin converting enzyme (ACE) gene was also tested. Design The DASH trial was a randomized outpatient feeding study comparing the effects on blood pressure (BP) of three dietary patterns: a control diet, similar to typical American intake; a ‘fruits and vegetables’ diet (F/V) that is rich in fruits and vegetables but otherwise resembles the control diet; and the DASH diet that is reduced in fats and that emphasizes fruits, vegetables and low-fat dairy products. Participants’ genotype was also determined. Setting Four clinical sites. Participants Adults with above-optimal BP or stage 1 hypertension. Intervention Participants ate one of the three dietary patterns for 8 weeks. Sodium intake and weight were held constant. In 355 of 459 DASH participants, DNA was extracted from leukocytes and genotyped for the G−6A ANG polymorphism and the D/I ACE polymorphism, by the polymerase chain reaction. Main outcomes Genotype at ANG and ACE loci; BP after 8 weeks of intervention diet. Results There was no association between ACE genotype and BP response. Associations with ANG polymorphism were significant: net systolic and diastolic BP response to the DASH diet was greatest in individuals with the AA genotype (−6.93/−3.68 mmHg) and least in those with the GG genotype (−2.80/0.20 mmHg). A similar relationship existed for the F/V diet. Conclusions ANG genotype is associated with BP response to the DASH diet. The AA genotype confers excess risk of hypertension and is associated with increased responsiveness to diet.

Hypertension Improvement Project (HIP): study protocol and implementation challenges

BackgroundHypertension affects 29% of the adult U.S. population and is a leading cause of heart disease, stroke, and kidney failure. Despite numerous effective treatments, only 53% of people with hypertension are at goal blood pressure. The chronic care model suggests that blood pressure control can be achieved by improving how patients and physicians address patient self-care.Methods and designThis paper describes the protocol of a nested 2 × 2 randomized controlled trial to test the separate and combined effects on systolic blood pressure of a behavioral intervention for patients and a quality improvement-type intervention for physicians. Primary care practices were randomly assigned to the physician intervention or to the physician control condition. Physician randomization occurred at the clinic level. The physician intervention included training and performance monitoring. The training comprised 2 internet-based modules detailing both the JNC-7 hypertension guidelines and lifestyle modifications for hypertension. Performance data were collected for 18 months, and feedback was provided to physicians every 3 months. Patient participants in both intervention and control clinics were individually randomized to the patient intervention or to usual care. The patient intervention consisted of a 6-month behavioral intervention conducted by trained interventionists in 20 group sessions, followed by 12 monthly phone contacts by community health advisors. Follow-up measurements were performed at 6 and 18 months. The primary outcome was the mean change in systolic blood pressure at 6 months. Secondary outcomes were diastolic blood pressure and the proportion of patients with adequate blood pressure control at 6 and 18 months.DiscussionOverall, 8 practices (4 per treatment group), 32 physicians (4 per practice; 16 per treatment group), and 574 patients (289 control and 285 intervention) were enrolled. Baseline characteristics of patients and providers and the challenges faced during study implementation are presented. The HIP interventions may improve blood pressure control and lower cardiovascular disease risk in a primary care practice setting by addressing key components of the chronic care model. The study design allows an assessment of the effectiveness and cost of physician and patient interventions separately, so that health care organizations can make informed decisions about implementation of 1 or both interventions in the context of local resources.Trial registrationClinicalTrials.gov identifier NCT00201136

Comprehensive lifestyle modification and blood pressure control: A review of the PREMIER trial

The PREMIER trial assessed the aggregate effect on blood pressure (BP) of nationally recommended lifestyle modifications in free‐living adults with high‐normal (stage 1) hypertension. Participants (N=810) were randomized to the advice‐only group; the established group (consisting of weight loss, increased physical activity, and reduced sodium and alcohol intake); or the established plus Dietary Approaches to Stop Hypertension (DASH) diet group (consisting of the established interventions in addition to the DASH dietary pattern). The primary outcome was change in systolic BP at 6 months. Net of advice only, mean systolic BP declined by 3.7 mm Hg for members of the established group (p<0.001) and 4.3 mm Hg for the established plus DASH group (p<0.001). The prevalence of hypertension decreased from a baseline of 38% to 17% in the established group (p=0.01) and to 12% in the established plus DASH group (p<0.001) compared with a decrease to 26% in the advice‐only group. The PREMIER trial demonstrated that persons with above‐optimal BP and stage 1 hypertension can make multiple lifestyle changes leading to better control of BP.

Informing Cancer Prevention Strategies for African Americans: The Relationship of African American Acculturation to Fruit, Vegetable, and Fat Intake

Acculturation has been associated with health-related behaviors in African Americans. We sought to determine if there is a relationship between acculturation and dietary intake in African Americans. African Americans in the PREMIER trial completed the African American Acculturation Scale (AAAS) and 2 nonconsecutive 24-h dietary recalls (n = 238). Analysis of variance (ANOVA) and canonical correlation were used to assess relationships between acculturation and dietary intakes. Canonical correlation (p = 0.05) showed that traditional African Americans had lower intakes of fruits/vegetables and milk/dairy with higher intakes of fats, meat, and nuts. This pattern was supported by differences in the ANOVA. African American acculturation is related to dietary intake. These findings have implications for the design of cancer-related public health messages targeted to African Amercans.

Executive summary: Guidelines (2013) for the management of overweight and obesity in adults

In 2008, the NHLBI initiated these guidelines by sponsoring rigorous systematic evidence reviews for each topic by expert panels convened to develop critical questions (CQs), interpret the evidence, and craft recommendations. In response to the 2011 report from the Institute of Medicine on the development of trustworthy clinical guidelines (1), the NHLBI Advisory Council recommended that the NHLBI focus specifically on reviewing the highest-quality evidence and partner with other organizations to develop recommendations (2,3). Accordingly, in June 2013 the NHLBI initiated collaboration with the ACC and AHA to work with other organizations to complete and publish the guidelines noted above and make them available to the widest possible constituency. Recognizing that the expert panels/work groups did not consider evidence beyond 2011 (except as specified in the methodology), the ACC, AHA and collaborating societies plan to begin updating these guidelines starting in 2014.
