A Dietary Nutrition survey of a Mountaineering Team at a Peak of 5,454m

To investigate the conditions and characteristics of dietary nutrition for short-term high altitude mountaineering expedition members. A total of 20 volunteers participated with a 4 day’ food weighing method and a 24 hour dietary review method to continuously record their food intake. Except fat and sodium, no energy or nutrients consumed by the individuals while on the high altitude mountain were up to the standard of intake reference intake(DRIs) for the Chinese. The energy consumption rate of the men was 48.29%, and for women 47.93% the quantity of water consumed was also not up to the DRIs standard. The men consumed 29.86% of recommended amount, and the women 31.43% the proportions of energy intake for men and women were unbalanced, and the proportions of fat for men and women were higher than those of energy intake(46.05% and 48.39%, respectively), the proportions of carbohydrates were low(40.93% and 38.45%, respectively), the proportions of daily meals of men and women were irregular, the proportion of lunches was low(25.83% and 21.35%, respectively). The differences in four measured values of mens’ weight, BMI and waist conference of mountaineering members before and after reaching high altitude and the summit had statistical significance, as did the differences in four measured values of womens’ waist circumference. The nutrient intake for short-term, high altitude mountaineering individuals was insufficient and the dietary pattern was irregular. The amount of all food types should be increased among mountaineering individuals and targeted measures should be taken based on the principles of a balanced diet and physiological changes that occur at high altitude.
