Abstract:
Objective To understand the prevalence of small for gestational age (SGA) in Zhuang population, and to analyze the potential factors of SGA. Methods A total of 3 839 live births in the Wuming District People’s Hospital and Wuming Maternal and Child Health Hospital from January 2016 to January 2018 were recruited. Random Forest, 2 test and Logistic regression model were used for statistical analyses. Results The incidence of SGA was 9.6% (368/3 839), and it was 6.9% (142/2 049) and 12.6% (226/1 790) for male and female infants respectively. Random Forest method showed that second-trimester intrauterine growth restriction’s importance score was the highest, but gestational week’s was the lowest. Also, seven important variables were selected by this method. Unconditional logistic regression analysis showed that parity <2, the height of mothers <1.55 m, insufficient gestational weight gain, second-trimester intrauterine growth restriction were risk factors for SGA, but pre-pregnancy BMI ≥18.5 kg/m2 and male infants were protective factors. Conclusions The incidence of SGA is slightly higher, among the Zhuang population in Guangxi. SGA is affected by many factors. Therefore, it is necessary to evaluate the status of intrauterine growth and adopt comprehensive measures to control and reduce the incidence of SGA.
