Abstract: Objective: To investigate the weight control in infertile patients with overweight/obesity, and to analyze the influencing factors of weight control. Methods: 130 patients with infertility within the period from July 2019 to January 2020 from Center for Reproductive Medicine of The First Hospital of Lanzhou University were selected by convenience sampling. The general information questionnaires were adopted. Body masses were monitored. The data of body mass was analyzed by the SPSS 20.0. The factors influencing body mass control were then explored. Results: 126 valid questionnaires were received. Body mass of infertile patients with overweight/obese was significantly decreased by (7.10±4.00) kg when compared with the weight before treatment, and the decreased range of body mass ≥ 10% in 49 patients (49/126, 38.89%). The multivariate linear regression analysis showed that the primary factors influencing the body mass control were patients′ basal metabolism, original body mass index (BMI), duration of overweight/obesity and body mass control time. Conclusions: The body mass control of overweight/obese patients with infertility before pregnancy should be improved. The individualized body mass control schemes are based on the patients′ basal metabolism and duration of overweight/obesity, as well as health education, so as to improve the pregnancy outcomes of infertile patients with overweight/obesity.
