Title, author's name and unit, preface, subject (crowd, materials, methods, results), discussion, conclusion, references, thanks, etc.
Writing a survey report on people's diet
Work procedure 1 Write an outline 2 Write the background and purpose 3 Describe the investigation method 4 Describe the basic situation of the investigated population 5 Describe the food intake 6 Describe the dietary energy and main nutrients intake of residents.
Comparison between the dietary structure of residents in Scheme 7 and dietary guidelines
1, the food is diverse, mainly cereals. This paper analyzes residents' consumption of various foods, cereal intake and food sources of residents' energy.
2. Eat more vegetables, fruits and potatoes. According to the recommended amount of vegetables, fruits and beans recommended by the Balanced Diet Pagoda, calculate the percentage of people who reach the recommended amount.
3, often eat milk, beans or their products. 4, often eat the right amount of fish, poultry, eggs, meat, eat less fat and meat oil.
5, diet and physical activity should be balanced and maintain a suitable weight. 6. Eat a light and salt-free diet. 7. Drinking should be restricted. Meal means not giving a limit.

Scope of application and advantages of weighing method
Weighing method is a commonly used dietary survey method. When weighing, we need to accurately grasp two aspects of information. One is the raw weight of various foods used in the kitchen and the cooked weight after cooking, thus obtaining the raw-cooked ratio of various foods. The second is to weigh the cooked food eaten by individuals, and then calculate the weight of various foods eaten by each person according to the above-mentioned raw-cooked ratio, and then calculate the daily intake of various raw foods for each person. To evaluate whether energy and various nutrients meet the requirements of supply standards and meet the normal nutritional needs of human body. Weighing method can be used to investigate the consumption of various foods in three meals a day in a catering unit (collective canteen or family) or individual.
2. The scope of application and advantages of retrospective method.
24-hour retrospective method is a retrospective dietary survey method that trained investigators collect dietary information through interviews, and it is the most commonly used survey method to obtain personal dietary intake at present. By asking the respondents about their actual diet in the past 24 hours, their food intake can be calculated and evaluated. Retrospective method can be used to investigate the food consumption of individuals in the family, and can also be used to describe the food intake of individuals in different groups. In practical work, the 3-day continuous investigation method is generally chosen. The most typical method is to use open investigation and face-to-face inquiry.
3. The scope of application, advantages and disadvantages of bookkeeping methods.
The bookkeeping method is to obtain the food situation of the respondents according to the food accounts, so as to obtain the total food consumption and the number of people eating in a certain period of time, calculate the average food consumption per person per day, and then calculate the energy and nutrients supplied by these foods according to the food composition table. This law applies to family surveys. Bookkeeping method can be used to investigate the dining situation for a long period of time, which is suitable for the investigation in different seasons throughout the year. However, the results of bookkeeping survey can only get the per capita dietary intake of the whole family or the collective, and it is difficult to analyze the individual dietary intake.
Human body measurement
The fundamental purpose of anthropometry is to evaluate the nutritional status of the body, especially the results of preschool children, which is often used to evaluate the nutritional status of a regional group. There are many indicators that can reflect the nutritional status of human body. People of different ages and physiological conditions choose different physical measurement indicators, and the measurement methods of indicators are also very different. For example, adult's commonly used physical fitness measurement indicators include height, weight, upper arm circumference, waist circumference, hip circumference and skin fold thickness, among which height and weight are the most important, and children's growth and development indicators include weight, height, sitting height, head circumference, chest circumference and upper arm circumference, among which height, weight, head circumference and chest circumference are the main indicators of children's physical fitness measurement.
The essential feature of standards is a kind of "unified regulation", and "unification is achieved by formulating, issuing and implementing standards" is the essence of standardization.

1 head circumference measurement
The tested baby takes a sitting position or supine position, and the measurer is located on the right or in front of the baby. Fix the zero point of the soft ruler on the upper edge of the right eyebrow arch of the head with the thumb of the left hand, return the soft ruler to the zero point through the occipital tuberosity (the most prominent point in the back of the head) and the upper edge of the left eyebrow arch, and read the reading where the soft ruler coincides with the zero point, taking centimeters as the recording unit and keeping one decimal place. Babies need rubber caps when measuring. When measuring, the soft ruler should be close to the skin and cannot be discounted. For people with long hair or braids, separate the hair up and down where the soft ruler passes, so that the soft ruler can stick to the hair.
2 determination of chest circumference
The baby lies on his back, naturally lying flat, so he is in a calm state. The measurer stands on the right side of the baby, fixes the zero point of the soft ruler on the lower edge of the nipple on the right side of the baby's chest with his left thumb, pulls the soft ruler with his right hand, so that it bypasses the right back with the lower edges of the lower corners of the two shoulder blades as the standard, and then returns to the zero point through the left side, thus reading the reading where the soft ruler coincides with the zero point, taking centimeters as the recording unit, and keeping one decimal place.
