Abstract To evaluate the dietary nutritional status of advanced women with infertility during assisted reproduction by diet balance index-16(DBI-16). Methods: 914 advanced pregnant women(≥35 years old) who had accepted assisted reproductive technology were selected in this study from June 2021 to June 2022. The diet of these women in the past 1 month was investigated by a semi-quantitative diet frequency questionnaire, and the dietary nutritional status of the women was evaluated by DBI-16. Results: There were no significant differences in the DBI HBS score among the women with different age, body mass index(BMI), or education levels(P＞0.05). The DBI LBS and DBI dietary quality distance(DQD) values of the women with 35-36 years old, with BMI <25kg/m2, or with university education level were significantly lower(P＜0.05), which of the women with 35-36 years old, with 37-38, and with ≥39 years old had increased gradually, which of the women with BMI≥25 kg/m2 and with BMI＜25 kg/m2 had increased gradually, and which of the women with university education level or above, the women with senior high school and junior college education levels, and the women with primary school and junior high school education levels had increased gradually(P＜0.05). There was no significant difference in the score of DBI-16 among the patients with different household registration or job types(P＞0.05). Among 914 women, 76.8% women consumed cereals nearly or reached the recommended daily level, and 23.2% women consumed cereals excessively. The daily fruit intake of 76.8% women approached or reached the recommended amount, and 23.2% women of which excessived. The daily intake of eggs and meat products of 66.3% women approached or reached the recommended amount, and 33.7% women of which excessive. The daily milk intake of 17.7% women of approached or reached the recommended levels, and 82.3% women of which were insufficient. The daily intake of fish and shrimp of 47.1% women approached or reached the recommended levels, and 53.0% women of which were insufficient. The daily intake of legumes of 58.9% women approached or reached the recommended levels, and 41.1% women of which were insufficient. The daily oil intake of 23.4% women approached or reached the recommended level, and 76.6% women of which exceeded the recommended level. The daily salt intake of 56.5% women approached or reached the recommended level, and 56.5% women of which were above the recommended level. The daily salt intake of 69.4% women approached or reached the recommended level, and 30.6% women of which were insufficient. 69.4% women consumed more than 8 kinds of food and 10.7% women consumed 5-7 kinds of food. The dietary quality of DBI HBS, DBI LBS and DBI DQD of 914 women was mostly divided into low level and almost no problem, followed by the medium level, and the high level. Conclusion: In the advanced women with infertility after assisted reproduction, the women with≥37 years old, the women with BMI ≥25 kg/m2, or the women with lower educational level have poor dietary nutritional status, which have a large space to improve their poor dietary nutritional status nutrition. There is a low level of imbalance in the overall dietary quality of the advanced women with infertility after assisted reproduction.
