Analysis of influencing factor of infant's fat mass index
Objective To explore influencing factors of fat mass index(FMI)of infants of different genders.Methods An infant's body composition cross-sectional study was carried out from October 2021 to December 2022 in Shandong province and healthy infants aged 1-12 months with single birth and no genetic metabolic disease were recruited as study subjects.The data of the infants were obtained through electronic questionnaire investigation and measurement of body composition.Finally,9 291 valid data were included.Multiple linear regression analysis was used to analyze influencing factors of FMI of the infants of different genders.Results The gestational age of the infants of different genders was significantly positively correlated with FMI:as compared with appropriate for gestational age infants(AGA),the FMI of large for gestational age(LGA)infants increased(β=0.086 and 0.078 respectively,both P＜0.001)and the FMI of the small for gestational age(SGA)infants decreased(β=-0.088 and-0.072 respectively,both P＜0.001).As compared with those male and female infants whose complementary foods were added after 6 months of age,the FMIs of these male and female infants whose complementary foods were added at 4-6 months increased,and the differences were significant(β=0.099 and 0.053 respectively,both P＜0.001).Compared with these infants whose parents'BMIs were normal,mother and father's obesity was significantly positively correlated with increased FMI of their male and female infants(β=0.058 and 0.070 respectively;β=0.054 and 0.058 respectively,both P＜0.001).And mother's low BMI was correlated significantly with decreased FMI of their male and female infants(β=-0.039 and-0.046 respectively,P=0.005 and 0.002 respectively).Also,gestational diabetes mellitus(GDM)was significantly correlated with decreased FMI of the male and female infants(β=-0.039 and-0.046 respectively,P=0.005 and 0.002 respectively).Gestational hypertension was significantly correlated with increased FMI of the male infants(β=0.028,P=0.038),and length of pure formula milk powder feeding was positively correlated with FMI of the female infants(β=0.029,P=0.046),while insufficient weight gain during pregnancy of the mother was significantly negatively correlated with FMI of the female infants(β=-0.033,P=0.032).Conclusion The influencing factors of infant'body composition mainly include weight-for-gestational age,infant's feeding pattern,adding time point of complementary foods,maternal weight gain during pregnancy and pregnancy diseases,etc.Effective intervention measures should be taken in early life of the infants to prevent,control and reduce occurrence of metabolic diseases.
