Obesity has emerged as the most potential cardiovascular risk factor and has raised concern among public and their health related issues not only in developed but also in developing countries. The Worldwide obesity occurrence has almost has gone three times since 1975. Research suggests there are about 775 million obese people in the World including adult, children, and adolescents. Nearly 50% of the children who are obese and overweight in Asia in are below 5 years. There is a steep incline of childhood obesity when compared to 1971 which is not only in developed countries but also in developing countries. A considerable amount of weight gain occurs during the transition phase from adolescence to young adulthood. It is also suggested that those adultswho were obese in childhood also remained obese in their adulthood with a higher metabolic risk than those who became obese in their adulthood. In India, the urban Indian female in the age group of 30-45 years have emerged as an 〝at risk population” for cardiovascular diseases. To understand how obesity can influence cardiovascular function, it becomes immense important to understand the changes which can take place in adipose tissue due to obesity. There are two proposed concepts explaining the inflammatory status of macrophage. The predominant cause of insulin resistance is obesity. Epidemiological and research studies have indicated that the pathogenesis of obesity-related metabolic dysfunction involves the development of a systemic, low-grade inflammatory state. It is becoming clear that targeting the pro-inflammatory pathwaymay provide a novel therapeutic approach to prevent insulin resistance, particularly in obesity inducedinsulin resistance. Some cost effective interventions that are feasible by all and can be implemented even in low-resource settings includes - population-wide and individual, which are recommended to be used in combination to reduce the greatest cardiovascular disease burden. The sixth target in the Global NCD action plan is to reduce the prevalence of hypertension by 25%. Reducing the incidence of hypertension by implementing population-wide policies to educe behavioral risk factors. Reducing cigarette smoking, body weight, blood pressure, blood cholesterol, and blood glucose all have a beneficial impact on major biological cardiovascular risk factors. A variety of lifestyle modifications have been shown, in clinical trials, to lower bloodpressure, includes weight loss, physical activity, moderation of alcohol intake, increased fresh fruit and vegetables and reduced saturated fat in the diet, reduction of dietary sodium intake, andincreased potassium intake. Also, trials of reduction of saturated fat and its partial replacement by unsaturated fats have improved dyslipidaemia and lowered risk of cardiovascular events. This initiative driven by the Ministry of Health and Family Welfare, State Governments, Indian Council of Medical Research and the World Health Organization are remarkable. The Government of India has adopted a national action plan for the prevention and control of non-communicable diseases (NCDs) with specific targets to be achieved by 2025, including a 25% reduction inoverall mortality from cardiovascular diseases, a 25% relative reduction in the prevalence of raised blood pressure and a 30% reduction in salt/sodium intake. In a nutshell increased BMI values can predict the nature of obesity and its aftermaths in terms inflammation and other disease associated with obesity. It’s high time; we must realize it and keep an eye on health status in order to live long and healthy life.

Abstract Several blood pressure guidelines recommend low sodium intake (<2.3 g/day, 100 mmol, 5.8 g/day of salt) for the entire population, on the premise that reductions in sodium intake, irrespective of the levels, will lower blood pressure, and, in turn, reduce cardiovascular disease occurrence. These guidelines have been developed without effective interventions to achieve sustained low sodium intake in free-living individuals, without a feasible method to estimate sodium intake reliably in individuals, and without high-quality evidence that low sodium intake reduces cardiovascular events (compared with moderate intake). In this review, we examine whether the recommendation for low sodium intake, reached by current guideline panels, is supported by robust evidence. Our review provides a counterpoint to the current recommendation for low sodium intake and suggests that a specific low sodium intake target (e.g. <2.3 g/day) for individuals may be unfeasible, of uncertain effect on other dietary factors and of unproven effectiveness in reducing cardiovascular disease. We contend that current evidence, despite methodological limitations, suggests that most of the world’s population consume a moderate range of dietary sodium (2.3–4.6g/day; 1–2 teaspoons of salt) that is not associated with increased cardiovascular risk, and that the risk of cardiovascular disease increases when sodium intakes exceed 5 g/day. While current evidence has limitations, and there are differences of opinion in interpretation of existing evidence, it is reasonable, based upon observational studies, to suggest a population-level mean target of <5 g/day in populations with mean sodium intake of >5 g/day, while awaiting the results of large randomized controlled trials of sodium reduction on incidence of cardiovascular events and mortality.

Introduction: While hypertension is a key treatable risk factor for cardiovascular disease, it is not controlled in an estimated 36 million US adults. Previous research has shown that nearly half of adults with disabilities have hypertension and that adults with disabilities are more likely to have hypertension than those without disabilities. However, no study has documented the prevalence of uncontrolled hypertension among the disability population. Our objectives were 1) to determine the prevalence of uncontrolled hypertension among adults with a disability, and 2) estimate the prevalence of awareness, treatment with blood pressure (BP)-lowering medication, and lifestyle factors among adults with disabilities who have uncontrolled hypertension. Methods: Using nationally-representative data from the 2001-2010 National Health and Nutrition Examination Survey for 10,805 participants aged ≥20 years with a disability (self-reported limitation in cognition, hearing, vision, or mobility), we examined the prevalence of hypertension (measured systolic BP ≥140, diastolic BP ≥90 or self-reported use of BP-lowering medication) and uncontrolled hypertension (systolic BP ≥140 or diastolic BP ≥90). Among those with uncontrolled hypertension, we estimated the prevalence of awareness (ever told by a doctor that had hypertension), treatment (self-reported use of BP-lowering medication), and lifestyle factors (measured body mass index and dietary sodium intake and self-reported aerobic physical activity and cigarette smoking). Results: Nearly 38% of US adults have a disability. Overall 46.0% (nearly 37 million) of US adults with disabilities have hypertension. Of those, nearly 20 million (52.4%) had uncontrolled hypertension. Over half of those with uncontrolled hypertension were aware and treated (52.9%), 13.6% were aware but untreated, and 33.4% were unaware. Among those with uncontrolled hypertension 40.5% were obese, 52.1% were physically inactive (had no bouts of aerobic physical activity per week that lasted ≥10 minutes), 18.2% were current smokers, and 62.0% had an average sodium intake of ≥2,300 mg per day. Conclusion: Over half of the 37 million adults with disabilities who have hypertension do not have it controlled; and of those, one third are unaware they have hypertension. This study highlights the need to regularly measure and monitor blood pressure among adults with disabilities. It also identifies adults with disabilities as an important population to include in public health efforts that support and encourage healthy behaviors that might improve BP control and lower risk for cardiovascular disease.

Background/Aims: National and international agencies recommend a reduction in dietary sodium intake. However, some have questioned the wisdom of these policies. The goal of this report was to assess the findings and quality of studies that have examined the relationship between dietary sodium and both blood pressure and cardiovascular disease. Methods: Literature review of the available observational studies and randomized controlled trials, including systematic reviews and meta-analyses. Results: A large body of evidence from observational studies and clinical trials documents a direct relationship between dietary sodium intake and the level of blood pressure, especially in persons with a higher level of blood pressure, African-Americans, and those who are older or have comorbidity, including chronic kidney disease. A majority of the available observational reports support the presence of a direct relationship between dietary sodium intake and cardiovascular disease but the quality of the evidence according to most studies is poor. The limited information available from clinical trials is consistent with a beneficial effect of reduced sodium intake on incidence of cardiovascular disease. Conclusions: The scientific underpinning for policies to reduce the usual intake of dietary sodium is strong. In the United States and many other countries, addition of sodium during food processing has led to a very high average intake of dietary sodium, with almost everyone exceeding the recommended goals. National programs utilizing voluntary and mandatory approaches have resulted in a successful reduction in sodium intake. Even a small reduction in sodium consumption is likely to yield sizable improvement in population health. Video Journal Club ‘Cappuccino with Claudio Ronco' at www.karger.com/?doi=368975.

The dietary sodium requirements for rats have been a matter of debate. Our hypothesis was that normal commercial rodent chow contains sodium in excess of dietary needs and that this could have a significant impact on cardiovascular and renal physiology. To investigate dietary sodium requirements, 3-wk-old weanling Sprague-Dawley rats were fed a custom pelleted diet containing no sodium that was isocaloric to normal commercial rodent chow. These rats were provided with two drinking bottles; one contained water, and the other contained 0.5% NaCl. Thus they could choose and consume sodium as needed. Age-matched controls received normal pelleted Harlan Teklad 22/5 rodent diet (0.5% sodium content) and water ad libitum. Body weight and liquid intake were monitored over 7 wk until the rats were 10 wk old. At the end of the study, blood pressure was recorded. Weekly sodium intake in the experimental group was only 15% of that reported for rats fed normal rodent chow beginning in the first week postweaning. Growth was identical in the two groups (7.8 ± 0.1 vs. 7.6 ± 0.1 g/day), as was the total fluid volume intake. Blood pressure was significantly lower in the experimental rats compared with controls (96 ± 4 vs. 122 ± 4 mmHg, P < 0.05). These data suggest that, when given the choice, rats will consume significantly less sodium than provided in commercial chow, without any alteration in their growth rate. Rats fed standard commercial rodent chow may consume at least seven times more sodium than is necessary. This suggests commercial rodent diets may force excess sodium to accommodate caloric intake.

Increased salt consumption is believed to induce high blood pressure (BP)-mediated organ damage, although it is not yet clear whether it reflects a generalized micro- and macrovascular malfunction independent of BP. Exceeding dietary sodium intake is acknowledged to be the main modifiable environmental risk factor for cardiovascular events that accounts for an increase in blood pressure and induces hypertension (HTN)-related target organ damage. Arterial stiffness is well known as an independent cardiovascular risk factor, and sodium intake may be a determinant of arterial stiffness. Even so, the studies that investigated the effect of dietary sodium reduction intake on arterial stiffness in humans provided inconclusive results. Therefore, we aim to perform a review of the available evidence of salt restriction and arterial stiffness and its impact on hypertensive patients.

The effect of different dietary salt contents (0.0035, 0.4, and 4%) on in vivo left ventricular (LV) geometry was studied by necropsy-validated echocardiographic methods in groups of 30 two-kidney, one-clip (2K, 1C) and one-kidney, one-clip (1K, 1C) male Wistar rats and two-kidney (2K) and one-kidney (1K) shams 9 wk after surgery. The salt-deficient diet was associated with lower body weight, higher plasma renin activity in both 2K,1C and 2K shams (P < 0.004) and higher hematocrit in 2K,1C (P < 0.02). Blood pressure was increased by high-salt diet in experimental groups but not in shams (P < 0.01). Increase in dietary sodium content was associated with increased cross-sectional area index (CSAI) and LV mass index in 2K rats independently of renal artery stenosis (P < 0.0007) and also in 1K shams (P < 0.01). LV end-diastolic dimension was greater in 1K,1C and 1K shams than in 2K,1C and 2K shams at every level of sodium intake and was directly related to atrial natriuretic factor levels in both 1K,1C (r = 0.68) and 2K,1C (r = 0.59). LV hypertrophy was independently predicted by blood pressure (P < 0.0006) and high-sodium diet (P < 0.05) in 1K rats (multiple r = 0.57, P < 0.001) and by high-sodium diet (P < 0.0001) and low hematocrit (P < 0.05) in 2K rats (multiple r = 0.76, P < 0.0001). Thus provision of normal or high sodium content in the diet was a more consistent stimulus to LV hypertrophy than the level of blood pressure.(ABSTRACT TRUNCATED AT 250 WORDS)

Dietary salt is made up of sodium and chloride, two essential minerals necessary for good health. Sodium is very important for our body to maintain fluid balance, blood volume, and blood pressure. However, many people consume more dietary sodium (from salt) than needed. Decreasing dietary sodium has received a lot of attention in recent years due to its association with high blood pressure (hypertension) and cardiovascular disease (Kloss, Meyer, Graeve, & Vetter, 2015). This publication explore ways to decrease sodium intake and the health effects of inadequate and excessive sodium intakes.

Background: Sodium intake has been related to several adverse health outcomes; such as, hypertension, and cardiovascular diseases. Processed foods are major contributors to the population&rsquo;s dietary sodium intake. The aim of the present study was to determine sodium levels in Mexican packaged foods; also to evaluate the proportion of foods that comply with sodium benchmark targets set by the UK Food Standards Agency (UK FSA) and those set by the Mexican Commission for the Protection of Health Risks (COFEPRIS). We also evaluated the proportion of foods that exceeded the Pan American Health Organization (PAHO) targets. Methods: This was a cross-sectional study that comprised data collected from the package of 2,248 processed foods from selected supermarkets of Mexico. Results: Many processed food categories contained excessive amount of sodium, being the processed meats (ham, bacon and sausages) those that have the highest concentrations. The proportion of foods classified as compliant in our sample was lower for international targets (FSA UK and PAHO) compared to the Mexican COFEPRIS criteria. Conclusions: These data provide a critical baseline assessment for monitoring sodium levels in Mexican processed foods.
