Analysis Of Mineral Substances In The Blood Of Pregnant Women From Three Cities In Northern China

Objectives:Mineral elements are crucial to pregnant women. To know the contents of mineral elements of pregnant women in different cities; learn the consequence of insufficiency in mineral elements for further study, and provide exact guidance for both nutritional education and intervention during pregnancy.Methods:Random drawing2429pregnant women in midtrimester (women who have been pregnant for13to28weeks) from Beijing Sijiqing Hospital(802in total); Harbin Nangang Hospital(717in total); Shanxi Jinzhong Woman and Children Hospital(910in total). Then divided them into three groups by age(group18～24, group25～29, and group>29). Investigate their basic condition,24/7inquire and note their nutrition intake, and record their food intake; the frequency of food-taking and the kinds of foods. Measure calcium, magnesium, iron, copper, zinc, etc, by collecting specimen of blood. According to these analyze and speculate the consequence of possibly influenced factors of food and exception in mineral elements to pregnant. Finally, analyze all these data and information with SPSS18.0.Results:1. Among these pregnant, no significant difference has been found in average age, energy intake or nutrient elements. Notably, the education level of pregnant of significant difference: which is highest in Beijing and lowest in Harbin. Also, the kinds of occupation is bound up with regions:in Beijing, the highest ratio of profession are unemployed, enterprise employee, state-owned company worker, medical personnel and educators. In Harbin, it is businessman, and in Shanxi, peasant. Obviously, income is also related to regions:The average monthly income of Beijing and Harbin citizens was2000-3000RMB while1000-2000RMB in Shanxi.2. The average contents of calcium were at a normal state in each city, and no significant difference has been found among these cities. For group25～29in all regions, no difference has been found in blood calcium. But for group18～24and group>29, the levels of blood calcium were significantly different:which was highest in Shanxi and lowest in Beijing. However, it was surprisingly that the ratio of insufficiency in calcium was lowest in Beijing and highest in Shanxi. Which means, pregnant over29years old stood the highest chance of calcium insufficiency.3. The total average contents of magnesium were at a normal state in each city. Even though they were similar but the difference was significant among the these three cities:Which was highest in Beijing and lowest in Harbin. For each age group, the contents of magnesium were still the highest in Beijing and lowest in Harbin. That is to say, the rate of insufficient of magnesium was at a low state and, there is little difference among these three cities.4. The average contents of iron were at a normal state in each city. In addition, no significant difference has been found among these three cities. Among these three cities, this parameter were highest in Beijing; lowest in Harbin(group>29) and lowest in Shanxi(18-29). However, the ratio of iron insufficiency was lowest in Beijing and highest in Shanxi. Among all investigated groups, group25～29maintains the lowest ratio of iron insufficiency.5. The average contents of copper were at a normal state in each city and, statistically vary among the three cities:among these cities, this parameter was highest in Harbin while lowest in Shanxi. For group25～29, no difference has been observed in the contents of blood copper. For group18～24and group>29, which vary most significantly, the level is at the lowest standard in Shanxi. However, the ratio of copper insufficiency is lowest in Beijing and highest in Shanxi. Which means we can safely draw the conclusion that people in age25～29is more likely to be insufficiency in copper.6. The average contents of zinc were at a normal state in each city and, statistically vary among the three cities:among these three cities, this parameter is highest in Beijing and lowest in Shanxi. For each group, significant difference has been observed in the concentration of blood zinc:the highest in Beijing and lowest in Shanxi. The ratio of zinc insufficiency was the lowest in Beijing and highest in Shanxi. All these facts above lead to a conclusion that pregnant from group18～24stood the highest chance of zinc insufficiency.1. Despite the fact that the total average contents of all these five kinds of mineral elements are at normal state among these three cities; energy intake and major nutrients intake show no significantly distinction, the insufficiency ratio of these five mineral elements varies regionally. Except for magnesium, the insufficiency ratio of all the rest four elements is highest in Shanxi and lowest in Beijing, which is obviously relevant to occupation, education, average monthly wage, etc. 2. Except for sufficiency in magnesium of all regions. Apparently, the insufficiency in calcium, iron, copper and zinc is relevant to age. Pregnant over29years old stands a high chance of being calcium insufficiency. Those of25～29years old are relatively being iron sufficient but copper insufficient. Those of18～24years old stand a high risk of zinc insufficiency. All these observations above can provide theoretical foundation for midtrimester pregnant in effective supplement of mineral elements.
