Abstract: Objective To analyze the current status and influencing factors for growth and development of 0 to 1-year-old infants of Gelao nationality,and to provide scientific reference for promoting the healthy growth and development of infants. Methods A total of 306 Gelao infants and their mothers from 7 minority villages of Wuchuan County were enrolled in this study from1st November, 2012 to 1st November,2013,and took physical examination and follow up for one year. SPSS 22.0 software was used for statistical analysis. Results The postpartum breastfeeding rate within 24 hours was 92.4%,the breastfeeding rate declined to 27.5% when infants was 6 months old. The average weight and length of Gelao boys were higher than those of girls,while the mean head circumference of boys was lower than that of girl infants at 6 months old (P<0.05).The weight of 3-month-old infants was lower than that of WHO standards (P<0.05).The average score of mothers'knowledge on maternal and child health care was 4.1±1.36. The incidence of severe growth retardation and low birth weight showed some differences in female infants and male infants at each age group (P<0.05). The incidence of severe growth retardation in male infants aged 3~8 months was higher than that in female infants. But there were no significant differences on the incidence of moderate to severe low head circumference and waist circumstance between male and female infants (all P>0.05). Logistic regression analysis indicated that growth and development of Gelao infants were influenced by gender,household annual income,fathers'education background,mothers'maternal and child health knowledge and food supplement (P<0.05). Conclusions There is still a gap on the growth and development between Gelao and WHO standards. And appropriate feedback should be given to improve healthy growth and development of infants.
