Objective To understand the status and related factors for complementary feeding of 6 to 23-month-old infants in Xinjiang,in order to provide relevant basis for scientific feeding of infants. Methods A stratified multi-stage sampling method was used to investigate infants aged 6 to 23 months old and main caregivers from Hotan Prefecture and Kashgar area in southern Xinjiang and Changji Hui Autonomous Prefecture in Northern Xinjiang from July 2017 to May 2018. Results 1) The pass rate of minimum diet diversity(MDD) was 63.22%(887/1 403),the pass rate of minimum meal frequency(MMF) was 57.95%(813/1 403),and the pass rate of minimum acceptable diet(MAD) was 42.69%(599/1 403). The eligible rates of MDD,MMF and MAD in urban infants aged 6 to 11 months old were lower than those in rural infants(P<0.05). The eligible rates of MDD and MAD in urban infants aged 12 to 17 months were significantly higher than those in rural infants(P<0.05),and the eligible rates of MMF and MAD in urban infants aged 18 to 23 months were significantly higher than those in rural infants(P<0.05). 2) The unqualified MMF of infants and young children in northern Xinjiang was 1.947 times higher than that in southern Xinjiang. The unqualified MMF of children with normal weight was 2.715 times higher than that in children with low birth weight. The unqualified MDD and unqualified MAD of families with children more than three were 1.709 and 1.571 times higher than those of families with children not more than two. Conclusions The eligible rate of MDD,MMF and MAD of 6 to 23-month-old infants in Xinjiang is relatively low. Infants living in the northern Xinjiang,with normal birth weight and with siblings more than two are high-risk population for unqualified feeding. It is suggested that health education and correct guidance on infant feeding should be given and strengthened,caregivers′ feeding habits and behaviors should be changed,thereby improving the status of infant feeding.
