| Background The nutrition intake and its sufficient status is positively correlated with dietary diversity, dietary guidelines of the world health organization (WHO), United States, Chinese are suggested to improve the quality of dietary nutrition by dietary diversity. Dietary Diversity Score (DDS) as a kind of evaluation method suitable for the rural residents’ Dietary nutritional status, which was widely use; But poor village residents’ dietary diversity status and its score at high altitude, there is little attention. the definition of high altitude of geography is1500-3500meters above sea level, most of the villages in yunnan residents living environment it is in this range, and this study selected three villages at a height of2580-2580meters above sea level, the other two villages between2000-2100meters; In this area, because of the limitation of temperature, most of thermophilic crops, including corn, beans, vegetables, etc are not suitable for planting, because of poverty, the high mountains, the lack of reservoirs and irrigation facilities and seasonal water shortage, more limit the kinds of crops and affect the food supply of the villagers. Therefore, yunnan poor dietary diversity situation in high altitude mountain village is uniqueness and worth for research.Objective To know the daily diet structure of five high altitude village in poor mountainous areas of yunnan province.evaluate dietary diversity and the status of sufficient nutrients intake, at the same time, analysis the nutritional problems of the crowd in specific environment, including different types, such as mountain, mid-levels district and the plain inter-mountains, provide basic data and Suggestions for nutritional education and promotion of new crop varieties and agricultural technology suited to high altitude and cold mountainous area.Methods Adopt the method of cross-reference, select three different types including Mountain,midlevels district and plains In high altitude mountain as project sites. using systematic sampling methods for dietary diversity survey, A family as a unit, according to residents roster extracted more than300family from1599households, mainly be responsible for the daily procurement and cooking meal women as investigation object. Using24hour dietary questionnaires and the form of face-to-face interviews to review basic dietary survey of rural households, sampling unit and the proportion of the total is more than16%.Results The dietary diversity evaluation and dietary structure (food intake rate between food group differences) of villages with different geographical environment and ethnic composition are differences,and faced with the specific nutritional problems that present a large contrast, But common nutritional problems are the intake rate of fish and seafood, dairy is low. dietary structure of three villages betwen2580-2700meters above sea level and another two villages betwen2000-2100meters above sea level have bigger difference, the former24hours16classes of dietary diversity score was8.6879+/-1.9646, cereal and potato as the main mode of food, beans intake low is the main problem. The DDS is7.14512.9188, mainly grains and potato is complementary. The latter DDS is7.14512.9188, mainly grains and potato is complementary, the three villages At an altitude of2500meters above, with vitA vegetables intake rate was significantly higher (52.9%,24.2%, P<0.001), fresh meat intake rate is higher (91.6%,66.1%, P<0.001), visceral class intake rate difference was not significant (9.2%,3.2%, P=0.105); But beans, nuts and seeds, food intake was associated with significantly lower rates (36.6%,62.9%, P<0.001), and a low rate of milk and dairy intake (5.5%,16.1%, P<0.01), fish and seafood intake rate of no statistical difference (5%,6.5%, P=0.650).Conclusions and recommendations The Geographical factors of some mountainous villages with relatively low altitude, location conditions and multi-ethnic gather to form the diet custom is conducive to the diversification of diet; And typical mountain village development of animal husbandry is positive factors to advantages improve dietary diversity, but by limit of residents’ cultural level and poor location condition, there are still many dietary nutritional problems. Should strengthen the propaganda and education, the use of local rich resources of vitA foods to prevent subclinical vitA lack (SVAD), especially for two village at2000-2100meters above sea level should strengthen the propaganda and education, advocate the residents eat more vegetables that are rich in vitA original; to maternal and child On the local high altitude mountainous area, should strengthen the LCP intake research, monitoring, and mission. Should advocate the intake of milk, beans and nuts for middle-aged and old women,and advocate the use of local rich in all kinds of dietary methionine and tryptophan resources make up the defects of mountainous area residents’ dietary pattern; Should focus attention on strengthening of the dietary nutrition status of local miao minority and hui people; Agricultural technology support and high quality varieties such as beans, peas, are particularly important to promotion for nutrition improvement of the three villages at an altitude of2500meters above. In view of the development of the mountains animal husbandry did not improve dairy intake among residents, should actively explore, through the method of animal husbandry to improve dairy nutrition. |
