[Effects of nutritional education on improvement of nutritional knowledge of infant's mothers in rural area in China].

OBJECTIVE: To investigate the knowledge, attitude and practice (KAP) of young children's mothers on infant feeding and to evaluate the effects of nutritional education in the rural areas. METHODS: A cluster sampling method was used to select the local health station. Five hundred and fifteen mothers, who had infants with age of 4 - 6 months, were recruited for the questionnaire survey on the nutritional knowledge in rural areas of Tianjin municipality. The mothers were randomly divided into intervention group I (160), intervention group II (180) and control group (175). The mothers in the intervention group I were educated with feeding guideline on infants and young children and had had Group lectures and advisory from experts about maternal and child nutrition for teaching them how to feed their children; while, the mothers in the intervention group II were trained with feeding guideline on infants and young children by themselves; and the mothers in the control group received routine guidance at the local health station. The follow-up evaluation on nutritional knowledge of the mothers in each group was carried out after 3 and 6 months intervention, respectively. RESULTS: The educational background had significant effect on KAP scores: KAP scores of the mothers with primary education or less (8.3 +/- 2.2) were significantly lower than that of the mothers educated with high school (9.4 +/- 1.6) and university (9.6 +/- 1.8) (LSD t = 3.70, P < 0.001). After being educated with feeding guideline on infants and young children, the knowledge of infant's mothers was greatly improved and KAP scores of the mothers after intervention were higher than that of the baseline (F = 183.556, P = 0.006); the percentage of correct answer on nutrition knowledge in the intervention groups was significantly higher than that of the control group. At six months of intervention, the KAP scores of intervention group I (12.0) and intervention group II (11.6) were higher than that of the control group (10.5) (LSD t = 5.96, P < 0.001; LSD t = 4.25, P < 0.001). CONCLUSION: Providing nutritional and health education to the infant's mothers should be helpful for improving infant's feeding pattern and ensuring the adequate growth and development of infants.
