Chronic non-communicable diseases.
ABSTRACT Chronic non-communicable diseases (NCD) account for almost 60% of global mortality, and 80% of deaths from NCD occur in low- and middle-income countries. One quarter of these deaths--almost 9 million in 2005--are in men and women aged <60 years. Taken together, NCD represent globally the single largest cause of mortality in people of working age, and their incidences in younger adults are substantially higher in the poor countries of the world than in the rich. The major causes of NCD-attributable mortality are cardiovascular disease (30% of total global mortality), cancers (13%), chronic respiratory disease (7%) and diabetes (2%). These conditions share a small number of behavioural risk factors, which include a diet high in saturated fat and low in fresh fruit and vegetables, physical inactivity, tobacco smoking, and alcohol excess. In low- and middle-income countries such risk factors tend to be concentrated in urban areas and their prevalences are increasing as a result of rapid urbanization and the increasing globalisation of the food, tobacco and alcohol industries. Because NCD have a major impact on men and women of working age and their elderly dependents, they result in lost income, lost opportunities for investment, and overall lower levels of economic development. Reductions in the incidences of many NCD and their complications are, however, already possible. Up to 80% of all cases of cardiovascular disease or type-2 diabetes and 40% of all cases of cancer, for example, are probably preventable based on current knowledge. In addition, highly cost-effective measures exist for the prevention of some of the complications of established cardiovascular disease and diabetes. Achieving these gains will require a broad range of integrated, population-based interventions as well as measures focused on the individuals at high risk. At present, the international-assistance community provides scant resources for the control of NCD in poor countries, partly, at least, because NCD continue to be wrongly perceived as predominantly diseases of the better off. As urbanization continues apace and populations age, investment in the prevention and control of NCD in low-and middle-income countries can no longer be ignored.

ABSTRACT: During the last century we have seen wide-reaching changes in diet, nutritional status and life expectancy. The change in diet and physical activity patterns has become known as the nutrition transition. At any given time, a country or region within a country may be at different stages within this transition. This paper examines a range of nutrition-related indicators for countries in Sub-Saharan Africa (SSA) and attempts to develop a typical model of a country in transition. Based on the availability of data, 40 countries in SSA were selected for analysis. Data were obtained from the World Health Organisation, Demographic and Health Surveys and the Food and Agriculture Organisation of the United Nations. Multiple linear regression analysis (MLRA) was used to explore the determinants of infant mortality. A six point score was developed to identify each country's stage in the nutrition transition. MLRA showed that underweight-for-age, protein and the percentage of exclusively breastfed infants were associated with the infant mortality rate (IMR). The majority of countries (n = 26) used in the analysis had nutrition transition scores of zero and one. Most of them had a high prevalence of infant mortality, children that were stunted or underweight-for-age, small percentages of women that were overweight and obese, and low intakes of energy, protein, and fat. Countries with the highest scores include South Africa, Ghana, Gabon, Cape Verde and Senegal which had relatively low IMRs, high levels of obesity/overweight, and low levels of underweight in women, as well as high intakes of energy and fat. These countries display classic signs of a population well established in the nutrition-related non-communicable disease phase of the nutrition transition. Countries in SSA are clearly undergoing a nutrition transition. More than half of them are still in the early stage, while a few have reached a point where changes in dietary patterns are affecting health outcomes in a large portion of the population. Those in the early stage of the transition are especially important, since primordial prevention can still be introduced.BMC Public Health 01/2011; 11:801. · 2.08 Impact Factor
Article: Benefits of smoking cessation[Show abstract] [Hide abstract]
ABSTRACT: Smoking affects cardiovascular disease (CVD) risk through multiple biologic mechanisms, including inflammatory and hemostatic factors as well as the development of atheroma. Smoking cessation rapidly reduces the risk of CVD and death in a wide range of populations; previous studies may have under-estimated the benefits, as most rely on self-reported smoking status at one point in time only. Smoking cessation also considerably increases life expectancy and quality of life. Early studies were mostly confined to men in Western populations, but recent studies have confirmed that the risk of smoking (and benefits of quitting) appears similar in low-and middle-income countries and in women. Given the high prevalence of smoking and increasing incidence of CVD, the public health benefits from quitting are likely to be substantial in most parts of the world, and this should remain a top public health priority.Current Cardiovascular Risk Reports 1(5).

ABSTRACT: To determine the opinions of infectious diseases professionals on the possibilities of monitoring patients with HIV in Primary Care. Qualitative study using in-depth interviews. Infectious Diseases Unit in the University Hospital «Virgen de la Victoria» in Málaga. Health professionals with more than one year experience working in infectious diseases. A total of 25 respondents: 5 doctors, 15 nurses and 5 nursing assistants. Convenience sample. Semi-structured interviews were used that were later transcribed verbatim. Content analysis was performed according to the Taylor and Bogdan approach with computer support. Validation of information was made through additional analysis, expert participation, and feedback of part of the results to the participants. Hospital care professionals considered the disease-related complexity of HIV, treatment and social aspects that may have an effect on the organizational level of care. Professionals highlighted the benefits of specialized care, although opinions differed between doctors and nurses as regards follow up in Primary Care. Some concerns emerged about the level of training, confidentiality and workload in Primary Care, although they mentioned potential advantages related to accessibility of patients. Physicians perceive difficulties in following up HIV patients in Primary Care, even for those patients with a good control of their disease. Nurses and nursing assistants are more open to this possibility due to the proximity to home and health promotion in Primary Care.Atención Primaria 12/2013; · 0.96 Impact Factor
