To analyze the trend and influencing factors of stunting among infants and young children (IYC) aged 6-23 months in rural areas of Liuzhou from 2017 to 2023, to provide evidence for early prevention and intervention for stunting.
Children nutrition improvement projects monitoring survey data of 4 175 IYC in Liuzhou between 2017 and 2023 were retrospectively analyzed. Complementary feeding practices were assessed using WHO/UNICEF 2021 IYC feeding indicators. The trend of stunting prevalence was analyzed by χ2 trend test, and the risk factors of stunting were analyzed by logistic regression analysis.
The prevalence of stunting in the IYC in rural Liuzhou decreased from 11.52% in 2017 to 3.85% in 2023 (χ2trend=41.914, P<0.001). Multivariate logistic regression analysis showed that mothers of Miao ethnicity (OR=1.63, 95%CI: 1.13-2.37), mothers of Dong ethnicity (OR=1.74, 95% CI: 1.24-2.44), middle school and below education (primary school or below: OR=1.94, 95% CI: 1.22-3.08; middle school: OR=1.64, 95% CI: 1.10-2.44), preterm birth (OR=4.27,95% CI: 2.89-6.30), term SGA (OR=3.04, 95% CI: 2.25-4.09), boys (OR=1.96, 95% CI: 1.51-2.55), aged 12-23 months (OR=1.93, 95% CI: 1.45-2.57) , unmet minimum meal frequency (OR=1.45, 95% CI: 1.08-1.95) were risk factors for stunting.Mother's occupation as agriculture (OR=0.57, 95% CI: 0.37-0.87), father's occupation as non-agriculture (OR=0.45, 95% CI:0.30-0.68), feeding and nutrition knowledge scores (OR=0.78, 95% CI: 0.70-0.86) were protective factors.
The prevalence of stunting among IYC aged 6-23 months in rural areas of Liuzhou showed a decreasing trend from 2017 to 2023,but was higher than the national average level. Attention needs to be paid to preterm births, term SGA, mothers from ethnic minorities or with low educational level, and complementary feeding practices for IYC, in order to reduce the incidence of stunting.
