TL;DR: Overall, it is shown that socioeconomic status, gender, age, parity, physical inactivity, and increased energy, fat, and sugar intake are powerful predictors of overweight and/or obesity.
Abstract: This review illustrates the outcomes of the nutrition transition in Sub-Saharan Africa (SSA) and its association with overweight and obesity; the relationship with the double burden of malnutrition is also explored. We describe the increase in overweight in nearly all Sub-Saharan African countries and present data on associated increased gross domestic product, and availability of energy, protein, fat, and sugar at country national levels. Predictors of overweight are described by means of various studies undertaken in SSA, and dietary intakes of numerous countries are presented. Overall, we show that socioeconomic status, gender, age, parity, physical inactivity, and increased energy, fat, and sugar intake are powerful predictors of overweight and/or obesity. The urgency for health interventions in countries in the early stages of the nutrition transition is emphasized, particularly in view of the fact that fat intake is still less than 30% of energy intake in nearly all Sub-Saharan African countries.

TL;DR: Countries in SSA are clearly undergoing a nutrition transition, and 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.
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.

TL;DR: The South African government must implement measures to improve the undesirably high level of food insecurity in poorer households, as indicated by a consistent emerging trend.
Abstract: OBJECTIVE: To assess the status of food security - i.e. access to food, food availability and food utilization - in South Africa. METHODS: A systematic search of national surveys that used the Community Childhood Hunger Identification Project (CCHIP) index to measure food security in South Africa over a period of 10 years (1999-2008) was conducted. Anthropometric data for children aged 1-9 years were used to assess food utilization, and household food inventory data were used to assess food availability. FINDINGS: Only three national surveys had used the CCHIP index, namely, the 1999 and 2005 National Food Consumption Surveys (NFCS) and the 2008 South African Social Attitudes Survey. These surveys showed a relatively large decrease in food insecurity between 1999 and 2008. However, the consistent emerging trend indicated that in poorer households women were either feeding their children a poor diet or skipping meals so their children could eat. In terms of food access and availability, the 1999 NFCS showed that households that enjoyed food security consumed an average of 16 different food items over 24 hours, whereas poorer households spent less money on food and consumed fewer than 8 different food items. Moreover, children had low mean scores for dietary diversity (3.58; standard deviation, SD: ± 1.37) and dietary variety (5.52; SD: ± 2.54) scores. In terms of food utilization, the NFCS showed that stunting in children decreased from 21.6% in 1999 to 18% in 2005. CONCLUSION: The South African government must implement measures to improve the undesirably high level of food insecurity in poorer households.

TL;DR: Although the amounts differed from place to place, even at the lowest values of the percentage of energy intake range, energy from street foods made a significant contribution to the diet.

TL;DR: A new book enPDFd preventing chronic diseases a vital investment to read is offered, offering you a new book to read and helping you to love reading.
Abstract: Let's read! We will often find out this sentence everywhere. When still being a kid, mom used to order us to always read, so did the teacher. Some books are fully read in a week and we need the obligation to support reading. What about now? Do you still love reading? Is reading only for you who have obligation? Absolutely not! We here offer you a new book enPDFd preventing chronic diseases a vital investment to read.

TL;DR: In this article, mental health issues often co-occur with other problems such as substance abuse, and they can take an enormous toll on individuals and impact a college or university in many ways.
Abstract: Mental health issues often co-occur with other problems such as substance abuse, and they can take an enormous toll on individuals and impact a college or university in many ways. There are staff and departments both onand off-campus who are concerned about the well-being of students and the impact of mental health issues, so partnerships around mental health promotion and suicide prevention make good sense.

TL;DR: Why slums are unhealthy places with especially high risks of infection and injury is discussed and it is shown that children are especially vulnerable, and that the combination of malnutrition and recurrent diarrhoea leads to stunted growth and longer-term effects on cognitive development.
