Existing dietary recommendations and nutrition counselling provided to mothers/caregivers at primary healthcare (PHC) facilities are reviewed and analysed to be consistent with food-based dietary guidelines (FBDGs) that are being developed for preschool children. Recommendations provided by the Integrated Management of Childhood Illness and the provincial Paediatric Case Management Guidelines, which are currently implemented at PHC facilities were reviewed. For FBDGs to be consistent with nutrition counselling that is provided to mothers/caregivers at these facilities, various principles need to be promoted. These include among others, exclusive and on-demand breastfeeding in the HIV-negative mother; exclusive breastfeeding with abrupt cessation preferably at 6 months or exclusive, safe and adequate formula feeding in the HIV-infected mother; the introduction of complementary feeds in all infants at 6 months; the provision of energy-dense and micronutrient-enriched (particularly, iron, zinc, calcium and vitamin A) complementary feeds; frequent visits to the healthcare facility; and physical activity aimed at encouraging a healthy lifestyle and preventing overweight and obesity in childhood. The FBDGs should be incorporated into nutrition and child health programmes and be reviewed and modified regularly.

Water is considered an essential nutrient because the body cannot produce enough water itself, by metabolism of food, to fulfil its need. When the quantity or quality of water is inadequate, health problems result, most notably dehydration and diarrhoea. As a result of contaminated water and poor hygiene, related infections are still a serious problem. Indeed, in the South African setting water availability and sanitation are critical issues because of the prevalence of childhood diarrhoea and also the HIV/AIDS crisis. Though considerable efforts have been made to improve the water and sanitation problems in South Africa - especially with regard to water supply infrastructure - there is still room for much improvement. Water is a healthy alternative to calorie-dense, non-nutritive beverages, such as artificial fruit drinks and soda. The latter should be avoided as they contribute little other than energy and may contribute to overweight and obesity. Also, they displace more nutritious foods from the child's diet. Consumption of fruit juice should also be limited. These issues highlight the need for a specific guideline relating to water intake in the paediatric food-based dietary guidelines.

The use of highly active antiretroviral therapy (HAART) in HIV-1 infection confers immunological and survival advantages, at the cost of induction of significant metabolic disturbances. These include insulin resistance, disturbances in lipid metabolism, glucose homeostasis, adipocyte physiology and body fat partitioning with peripheral lipoatrophy and visceral obesity. These metabolic disturbances produce clinical manifestations which impact on the future health of the HIV-infected patient, including hyperlipidaemia, lipodystrophy, metabolic syndrome, cardiovascular disease and type 2 diabetes. These conditions are evident in the relative short term as HAART (and possibly HIV infection) appears to accelerate their pathogenesis. The current understanding of the mechanisms and time courses for developing metabolic complications on HAART is reviewed in this paper. The efficacy of therapeutic interventions for insulin resistance, hyperlipidaemia, body fat partitioning disorders and metabolic syndrome is summarized.

Patients with HIV infection are at risk of cardiovascular disease from the same factors posing risk in the general population--eg, smoking, dyslipidemia, hypertension, obesity, and diabetes. HIV infection itself and antiretroviral therapy pose additional risk, but available data indicate that the relative rate of myocardial infarction is low and declining in the HIV-infected population. Cardiovascular risk should be addressed before initiation of antiretroviral therapy and frequently during follow-up, and decisions to alter therapy on the basis of adverse changes in metabolic risk factors should be made on an individual basis. Virologic control is the primary goal for HIV-infected persons with cardiovascular risk, and is the primary consideration in determining when to start antiretroviral therapy and when to change regimens. This article summarizes a presentation on cardiovascular risk and risk management in HIV-infected persons made by Oluwatoyin Adeyemi, MD, at an International AIDS Society-USA Continuing Medical Education course in Chicago in May 2007.

Phenolic compounds are widely present in the plant kingdom. Many epidemiological studies have indicated that consumption of some plant-derived foodstuffs with high phenolic content is associated with the prevention of some diseases and that these compounds may have similar properties to antioxidants, antimutagenic agents, antithrombotic agents, anti-inflammatory agents, anti-HIV-1, and anticancer agents. However, obesity is an important topic in the world of public health and preventive medicine. Relationships between body mass index, waist circumference, or waist-to-hip ratio and the risk of development of some diseases (such as heart disease, dyslipidemia, hypertension, non-alcoholic fatty liver disease, diabetes, kidney failure, cancer, stroke, osteoarthritis, and sleep apnea) have been observed. Evidence that phenolic compounds have beneficial effects in fighting obesity is increasingly being reported in the scientific literature. These in vitro and in vivo effects of phenolic compounds on the induction of pre-adipocytic and adipocytic apoptosis and inhibition of adipocytic lipid accumulation are considered in detail here. This review presents evidence of their inhibitory effects on obesity and their underlying molecular signaling mechanisms.

Visceral obesity is associated with insulin resistance, but the association of other regional adipose depots with insulin resistance is not understood. In HIV infection, buffalo hump (upper trunk fat) is associated, but the association of upper trunk fat with insulin resistance has not been examined in controls. To determine the independent association of adipose depots other than visceral with insulin resistance, we performed a cross-sectional analysis of controls and HIV-infected subjects in the Fat Redistribution and Metabolic Change in HIV Infection (FRAM) study, who had measurements of glucose, insulin, and adipose tissue volumes by whole-body magnetic resonance imaging. We studied 926 HIV-positive persons from 16 academic medical center clinics and trials units with demographic characteristics representative of US patients with HIV infection and 258 FRAM controls from the population-based Coronary Artery Risk Development in Young Adults study. We measured visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volume in the legs, arms, lower trunk (back and abdomen), and upper trunk (back and chest) and assessed their association with the homeostasis model of assessment (HOMA) and HOMA >4 by stepwise multivariable analysis. The prevalence of HOMA >4 as a marker of insulin resistance was 28% among controls compared with 37% among HIV-infected subjects (P = 0.005). Among controls, those in the highest tertile of upper trunk SAT volume had an odds ratio (OR) of 9.0 (95% confidence interval [CI]: 2.4 to 34; P = 0.001) for having HOMA >4 compared with the lowest tertile, whereas in HIV-positive subjects, the OR was lower (OR = 2.09, 95% CI: 1.36 to 3.19; P = 0.001). Among controls, the highest tertile of VAT volume had an OR of 12.1 (95% CI: 3.2 to 46; P = 0.0002) of having HOMA >4 compared with the lowest tertile, whereas in HIV-positive subjects, the OR was 3.12 (95% CI: 2.0 to 4.8; P < 0.0001). After adjusting for VAT and upper trunk SAT, the association of other SAT depots with HOMA >4 did not reach statistical significance. Thus, VAT and upper trunk SAT are independently associated with insulin resistance in controls and in HIV-infected persons.

Whereas common infectious and parasitic diseases such as malaria and the HIV/AIDS pandemic remain major unresolved health problems in many developing countries, emerging non-communicable diseases relating to diet and lifestyle have been increasing over the last two decades, thus creating a double burden of disease and impacting negatively on already over-stretched health services in these countries. Prevalence rates for type 2 diabetes mellitus and CVD in sub-Saharan Africa have seen a 10-fold increase in the last 20 years. In the Arab Gulf current prevalence rates are between 25 and 35% for the adult population, whilst evidence of the metabolic syndrome is emerging in children and adolescents. The present review focuses on the concept of the epidemiological and nutritional transition. It looks at historical trends in socio-economic status and lifestyle and trends in nutrition-related non-communicable diseases over the last two decades, particularly in developing countries with rising income levels, as well as the other extreme of poverty, chronic hunger and coping strategies and metabolic adaptations in fetal life that predispose to non-communicable disease risk in later life. The role of preventable environmental risk factors for obesity and the metabolic syndrome in developing countries is emphasized and also these challenges are related to meeting the millennium development goals. The possible implications of these changing trends for human and economic development in poorly-resourced healthcare settings and the implications for nutrition training are also discussed.

Objective was to assess dietary intake and physical activity in a Canadian population sample of male patients with HIV and metabolic abnormalities and to compare the data to Canadian recommendations. Sixty-five HIV-infected men with at least one feature associated with the metabolic syndrome (insulin resistance, dyslipidemia, central obesity, or lipodystrophy) were enrolled. Results from 7-day food records and activity logs were compared to the Dietary Reference Intakes and recommendations of Canada's Physical Activity Guide, respectively. Anthropometric data were also measured. Fifty-two percent of the subjects were overweight, another 15% were obese. However, energy intake (mean+/-SEM) (2153+/-99 kcal/d) was lower than the estimated requirement (2854+/-62 kcal/d; p<0.0001), and 84.5% of the patients reached the recommended minimum of 60 min of mild or 30 min of moderate daily exercise. Intake was adequate for protein, but high for fat and cholesterol in 40% of patients. No patient reached the recommendation for fiber. Intake from diet alone was suboptimal for most micronutrients. Prevalence was highest for low vitamin E (91% of patients) and magnesium (68%) intake, and high sodium intake (72%). In summary, a large proportion of HIV patients with metabolic abnormalities were overweight or obese. However, this was not associated with high energy intake, or reduced physical activity. High fat, low fiber and inadequate micronutrient intakes were prevalent.

Choosing a contraceptive method is difficult in women with a disease or presenting specific risk factors. The possible life-threatening effects of the contraceptive on the disease and the possible drug interactions should be taken into consideration. In this article, we will address the issues faced in patients with neurological diseases (epilepsy, brain tumor, migraine, prolactin-secreting adenoma), vascular diseases (venous thrombosis, biological thrombophilia, arterial diseases), metabolic disorders (obesity, dyslipemias, diabetes), uterine diseases (fibromas, endometriosis), renal failure, benign and malignant breast diseases as well as in HIV-positive women. Unfortunately, the available scientific data are insufficient for several of these conditions, which leads to a non-validated management. Controlled studies are needed to improve knowledge.

The aim of the present review was to: (i) highlight epidemiological and other studies that have generated important data on the harmful patterns of drinking that increase the risk for chronic diseases, including alcohol dependence, and on the mechanisms by which alcohol produces and, in some instances, may protect against damage; and (ii) discuss a conceptual basis for quantifying risk criteria for alcohol-induced chronic disease based on the quantity, frequency, and pattern of drinking. The relationship between heavy drinking and risk for adverse health conditions such as alcoholic liver disease (ALD), dementia, and alcohol dependence is well known. However, not everyone who drinks chronically develops ALD or dementia, and the major risk factors for disease development and the mechanisms by which this occurs have remained unclear. Large-scale, general population-based studies have provided the evidence by which quantifying the frequency of a pattern of high-risk drinking can be related directly to risk and the severity of alcohol dependence. Cellular and molecular biology studies have identified the major pathways of alcohol metabolism and how genetics and the environment can interact in some individuals to further increase the risk of organ damage. Extant databases should allow scientists and clinicians jointly to develop the framework for quantifying the drinking patterns that increase the risk of alcohol-induced organ pathologies, to develop clinical practice guidelines, such as those used to diagnose other common complex diseases (e.g. diabetes and hypertension), and to propose future studies for refining such guidelines. Attention must be paid to comorbid conditions such as hepatitis B and C infections, HIV, obesity, and environmental exposures other than alcohol. Developing trait and state biomarkers is critical to the process of discovery and to fulfilling the promise of personalized medicine.
