Nationwide shifts in the double burden of overweight and underweight in Vietnamese adults in 2000 and 2005: two national nutrition surveys

<p>Abstract</p> <p>Background</p> <p>In developing countries, overweight prevalence is increasing while underweight prevalence is still high. This situation is known as the double nutrition burden. Both underweight and overweight are related to increased risk of chronic non-communicable diseases, reduced well-being and quality of life. This study aims to compare the prevalence of overweight and underweight among Vietnamese adults in 2000 and 2005.</p> <p>Methods</p> <p>The study was based on two nationally representative surveys, the National Nutrition Survey 2000 (14,452 subjects) and the National Adult Obesity Survey 2005 (17,213 subjects). Adults aged 25-64 years were sampled to be nationally representative. Multiple multinomial logistic regression analysis was used to investigate the association of underweight and overweight with socio-economic indicators.</p> <p>Results</p> <p>The distribution of BMI across the population and population groups indicated a shift towards higher BMI levels in 2005 as compared to 2000. The nationwide prevalence of overweight (BMI ≥ 25 kg/m²) and obesity (BMI ≥ 30 kg/m²) was 6.6% and 0.4% respectively in 2005, almost twice the rates of 2000 (3.5% and 0.2%). Using the Asian BMI cut-off of 23 kg/m²the overweight prevalence was 16.3% in 2005 and 11.7% in 2000. In contrast, the underweight prevalence (BMI < 18.5 kg/m²) of 20.9% in 2005 was lower than the rate of 25.0% in 2000. Women were more likely to be both underweight and overweight as compared to men in both 2000 and 2005. Urban residents were more likely to be overweight and less likely to be underweight as compared to rural residents in both years. The shifts from underweight to overweight were clearer among the higher food expenditure levels.</p> <p>Conclusions</p> <p>The double nutrition burden was clearly present in Vietnam. The distribution of BMI across the population groups generally indicated a shift towards higher BMI levels in 2005 as compared to 2000. The prevalence of overweight was increased while the declined level of undernutrition was still high in 2005. The shifts of underweight to overweight were most obvious among population groups with higher food expenditure levels.</p

Provision Of Vitamin A Through Utilization Of Local Food Materials In Rural Parts Of Western Kenya

High prevalence and the negative consequences of the deficiencies resulting from inadequate intake of iron, iodine and vitamin A have resulted in focused global efforts to alleviate them. Vitamin A deficiency which has serious consequences can be prevented by consumption of vitamin A rich foods. This study was undertaken to determine the viability of locally available foods in providing vitamin A to the impoverished populations in rural areas of Kenya. A cross-sectional survey was carried out in Butere-Mumias District of Western Province, Kenya from December 2003 to February 2004. The study compared the potential contribution of local foods to the provision of vitamin A, to the diets of children aged 12-71 months in the two divisions of Butere and Khwisero, as based on the Helen Keller International (HKI) method. Vitamin A rich foods consumed in the two study areas are dark green leafy vegetables, kales, papaya margarine, orange/yellow fleshed sweet potatoes, eggs and ripe mangoes. Butere and Khwisero divisions where the study was conducted are adjacent to each other. Butere division had an ongoing nutrition intervention project to promote African leafy vegetables, while Khwisero division did not. Of the 16 clusters surveyed, consumption of vitamin A was insufficient in the six of the eight communities in Butere, and three of the eight communities, in Khwisero. The frequency of consumption of vitamin A-rich foods in the study area fell below the threshold values of the HKI Method. Consumption of these foods was not regular as planting was done on an ad hoc basis especially in Khwisero division in areas which were not reached by the on-going campaign in the Butere division. Vitamin A deficiency was most likely a public health problem in the two divisions. This study recommends increased activities in the area to control vitamin A deficiency, prophylactic vitamin A supplementation and efforts to increase vitamin A consumption

EFFECT OF MALTING ON PROTEIN DIGESTIBILITY OF SOME SORGHUM (Sorghum bicolor) VARIETIES GROWN IN KENYA

Protein digestibility of sorghum is generally low. Malting is one of the processing methods which can be applied to improve this digestibility. It is a method whose technology is well known by local communities in Kenya. The objective of this study was to investigate the effect of malting on the digestibility of some varieties of sorghum grain grown in Kenya. Protein digestibility in the grain and malt was determined using porcine pepsin. In raw unmalted sorghum, the protein digestibility ranged from 0% in the high tannin varieties of Essuti, IS 8613, Nakhadabo and Seredo to 66.4% in the low tannin IESV 91022. Cooking decreased the digestibility of all the sorghum grain whose digestibility was above 0%, mostly the low tannin varieties. When the sorghum grain was malted, the digestibility ranged from a minimum of 45.5% in Essuti to 88.7% in KM 1 in the raw sorghum. In the cooked malted sorghum, the digestibility ranged from 23.7% in Seredo to 100% in the low tannin varieties of KM1, IESV 91022 and KAT 386. There were significant differences (

Planting seeds for the future of food

The health and wellbeing of future generations will depend onhumankind's ability to deliver sufficient nutritious food to a world population in excess of 9 billion. Feeding this many people by 2050 will require science-based solutions that address sustainable agricultural productivity and enable healthful dietary patterns in a more globally equitable way. This topic was the focus of a multi-disciplinary international conference hosted by Nestle in June 2015, and provides the inspiration for the present article. The conference brought together a diverse range of expertise and organisations from the developing and industrialised world, all with a common interest in safeguarding the future of food. This article provides a snapshot of three of the recurring topics that were discussed during this conference: soil health, plant science and the future of farming practice. Crop plants and their cultivation are the fundamental building blocks for a food secure world. Whether these are grown for food or feed for livestock, they are the foundation of food and nutrient security. Many of the challenges for the future of food will be faced where the crops are grown: on the farm. Farmers need to plant the right crops and create the right conditions to maximise productivity (yield) and quality (e.g. nutritional content), whilst maintaining the environment, and earning a living. New advances in science and technology can provide the tools and know-how that will, together with a more entrepreneurial approach, help farmers to meet the inexorable demand for the sustainable production of nutritious foods for future generations.
