表 2. Statistical characteristics of the main variables (n=1002).

主要变量统计特征（n=1002）

Main variable	Observation variables	Case (%) or
AB: attitude of behavior; SN: subjective norms; BI: behavioral intention; FB: feeding behavior. (1-5): The relevant items of attitude of behavior and behavioral intention are responded to on a 5-point Likert scale, with the scores ranging between 1 being strongly disagree and 5 being strongly agree. (1-25): The relevant items of subjective norms are also responded to on a 5-point Likert scale. For each of the three items of subjective norms, there are a pair of questions measuring the normative beliefs and compliance motivation, and the scores, therefore, range between 1 and 25.

	AB2: Adherence to MNP feeding will make the baby grow taller and stronger (1-5)	4.10±0.89
	AB3: Adherence to correct feeding of MNP can help prevent the baby from developing anemia (1-5)	3.77±0.82
SN	SN1: Feeding the baby MNP as recommended by the family (1-25)	15.45±6.95
	SN2: Feeding the baby MNP as recommended by the best friend (1-25)	16.96±4.04
	SN3: Feeding the baby MNP as recommended by the doctor (1-25)	20.95±3.97
BI	The likelihood of continued feeding of MNP to the baby according to the requirements in the future (1-5)	3.57±1.60
FB	Effective feeding
	No	446 (44.51)
