目的探索我国农村地区2岁以下婴幼儿离乳期家庭膳食改善方法,观察离乳食干预对预防儿童营养性贫血的短期效果。方法本研究对赵县农村6~11月龄儿童家长进行增加瘦肉摄入和增加蔬菜摄入的健康教育,评估干预措施改善婴幼儿的喂养行为和升高血红蛋白(Hb)浓度的效果。结果干预组和对照组分别有149和114名儿童完成了6个月的干预和随访。相对于入选时,3个月随访时干预组的儿童自身Hb浓度升高值为(2.65±14.38)g/L,高于对照组[(-0.18±11.21)g/L],差异无统计学意义(P=0.074);6个月随访时干预组升高为(8.33±15.85)g/L,高于对照组[(4.32±14.00)g/L],差异有统计学意义(P=0.034)。3个月随访时干预组的儿童的食物种类多样率(89.9%)高于对照组(78.9%),差异具有统计学意义(P=0.014);而6个月随访时,干预组(83.1%)与对照组(86.8%)的差异无统计学意义(P=0.405)。干预组的儿童3个月和6个月随访时24h瘦肉食入量[依次为(6.94±9.07)g和(7.96±13.90)g]皆高于对照组[依次为(2.42±6.10)g和(4.54±9.19)g],差异具有统计学意义(P=0.000和P=0.024)。结论通过家庭膳食干预,离乳期儿童的食物种类和瘦肉食入增加,Hb水平显著提高,营养性贫血患病率降低。儿童24h瘦肉食入量有所增加,虽然仍低于我国和发达国家的推荐量,但是营养改善效果已经明确初显。
Objective To explore the methods for improving the family diet of infants under 2 years of age in rural areas in China and to observe the short-term effect of the intervention of lactation diet on the prevention of childhood nutritional anemia. Methods In this study, health education was given to parents of children aged 6 ~ 11 months in rural areas of Zhao County to improve lean meat intake and increase vegetable intake, and to evaluate intervention effects to improve infant feeding behavior and increase hemoglobin (Hb) concentration. Results A total of 149 and 114 children, respectively, completed intervention and follow-up for 6 months in intervention group and control group. Compared with the control group, the Hb concentration in the intervention group was (2.65 ± 14.38) g / L at 3 months of follow-up, higher than that in the control group [(-0.18 ± 11.21) g / L] (P = 0.074). Compared with the control group [(4.32 ± 14.00) g / L], the intervention group increased to (8.33 ± 15.85) g / L at 6 months follow-up ). At 3-month follow-up, the diversity of food groups (89.9%) in intervention group was significantly higher than that in control group (78.9%) (P = 0.014) ) And control group (86.8%), the difference was not statistically significant (P = 0.405). In the intervention group, the intake of lean lean meat (6.94 ± 9.07g and (7.96 ± 13.90g)] at 3 and 6 months follow-up were all higher than those in the control group [followed by (2.42 ± 6.10) g and (4.54 ± 9.19) g], the difference was statistically significant (P = 0.000 and P = 0.024). Conclusions With the help of family dietary intervention, the food type and lean meat intake of children during lactation increased significantly, Hb level increased significantly, and the prevalence of nutritional anemia decreased. Children 24h lean food intake has increased, although still below the recommended amount of China and developed countries, but the effect of nutrition improvement has been clearly pronounced.
