本篇研究目的是调查中国农村地区产妇出院时的母乳喂养率及其影响因素。该婴儿喂养调查采用了前瞻性队列研究方法,于2010年至2011年期间在中国四川省江油市进行。统计方法使用了邏輯斯(logistic)回归分析,用于确定产妇出院时母乳喂养率的影响因素。本研究共调查了695名母亲,其年龄分布于18至44岁。结果显示,产妇出院时的母乳喂养率为93.5%(95% CI:91.7-95.3)。产妇所认为的婴儿父亲对母乳喂养的偏好和实际出院时的母乳喂养情况呈正相关(OR=4.46, 95% CI:2.15-9.28)。其余的影响因素包括:住院期间受到来自医院员工的母乳喂养支持(OR=3.41, 95% CI:1.58-7.34)和在怀孕期间或生产之后决定喂养方式(OR=0.46, 95% CI: 0.22-0.93)。总之,建议在住院期间给予产妇全方面的母乳支持,以及开展针对准父母的教育课程,从而进一步提高中国农村地区的产妇出院时母乳喂养率。
This study aimed to investigate the rate of breastfeeding at discharge and associated influencing factors in rural China. A prospective cohort study of infant feeding practices was undertaken during 2010-2011 in Jiangyou city, Sichuan Province of China. Logistic regression analysis was performed to ascertain pertinent factors affecting the prevalence of any breastfeeding at discharge. The participants consisted of 695 mothers aged 18-44 years. The breastfeeding rate at discharge was 93.5% (95% CI: 91.7-95.3). Perceived paternal breastfeeding preference was positively associated with actual breastfeeding at discharge (OR=4.46, 95% CI: 2.15-9.28). Other significant determinants were 'receiving breastfeeding support' from staff during hospital stay (OR=3.41, 95% CI: 1.58-7.34) and making the decision on feeding method during pregnancy or after childbirth (OR=0.46, 95% CI: 0.22-0.93). In conclusion, provision of comprehensive breastfeeding support in hospital and education programs targeting expectant and future parents are recommended to further increase the rate of breastfeeding at discharge in rural areas of China.
