Algorithm of personalized nutrition prescription for pregnant women

Current guidelines provide recommendations of daily calorie intake for pregnant woman according to BMI,

gestational age and individual weight/height. However, the factors for the recommendation only focus on the

statistic information of the pregnant woman, which neglects the dynamic change of the pregnant woman and

actual fetal development during the pregnancy.

A method was proposed to adapt the calorie intake recommended by the guidelines for the pregnant

woman in view of the weight gain of the pregnant woman and the fetal development indicated by fetal

size determined. The association between the fetal development and the weight gain is taken into

account for calorie intake recommendation, which helps to facilitate a more delicate and effective

coaching.

An embodiment for the adaptation criteria is illustrated as following. The scenarios in the red rectangular may be considered as the same situation based on the available guidelines.

Note: 1. Energy coefficient is a coefficient to calculate daily calorie intake formula, where the formula is a prior art and not illustrated. 2. Fetal age is indicated by the fetal size determined by regular ultrasound.

Pregnancy nutritional clinics can help pregnant women to get right amount of energy and nutrients, control weight gain, prevent and manage adverse maternal and foetal issues relevant to diet and lifestyle, such as excessive/insufficient weight gain, gestational diabetes mellitus, anaemia, intrauterine growth restriction, caesarean delivery, macrosomia, large for gestation age (LGA), small for gestational age (SGA) and so on. According to pregnant woman’s personal conditions, the physician provides corresponding recommendations, including but not limited to

 Daily calorie intake

 Macronutrient / micronutrient intakes

 Food types & intakes, such as grains, vegetables, fruits, meats, eggs, fishes, milks, soybeans, nuts, oils, etc.

 Nutritional prescription, like specific foods & amount for each primary or auxiliary meal

 Recommended recipes

 Other dietary and lifestyle advices

Personalized daily calorie intake is one of the core recommendations of overall pregnancy nutritional advices. Given a certain amount of daily calorie intake, suitable macronutrient / micronutrient intakes (Table 1) and food types & intakes (Table 2) could be looked up from the dietary guidelines [1], and nutritional prescription and recipes could be worked out accordingly.
