Purpose

The main objective of this study is to assess the applicability and robustness of the information motivation behavioural skills (IMB) model in determining dietary supplement usage of pregnant and breastfeeding women. More specifically, we examine the indirect effects of online social capital and internet use for health information on dietary supplement usage through self-efficacy and the moderating role of educational attainment.

Design/methodology/approach

Data was collected from 415 pregnant and breastfeeding Italian women using a self-administered questionnaire. Hypotheses were tested using Hayes's (2013) PROCESS macro for SPSS.

Findings

Internet use for health information is directly associated with dietary supplement usage. Online social capital and internet use for health information positively influence dietary supplement usage through self-efficacy. However, the results from moderated mediation analyses show that the mediation effects are moderated by educational attainment so that indirect relationships were stronger among women with a lower level of education than among those with a higher level of education.

Practical implications

Dietary supplement marketers and public health agencies can develop and implement dietary supplement promotional materials and interventions by disseminating information through the internet and social media and by strengthening social ties on online networking sites.

Originality/value

The originality of this study lies in the use of the IMB model as a theoretical framework to examine the mediating role of self-efficacy and the moderating role of education in explaining the mechanism of how online social capital and internet use for health information influence dietary supplement usage.

妊娠和哺乳期膳食补充剂的使用：在线社会资本和健康信息寻求行为的作用

目的

这项研究的主要目的是评估信息动机行为技能（IMB）模型在确定孕妇和哺乳期妇女膳食补充剂使用中的适用性和鲁棒性。更具体地说，我们通过自我效能和受教育程度的调节作用，研究了在线社会资本和互联网对健康信息的间接影响对膳食补充剂的使用。

设计/方法/方法

使用自我管理的问卷调查收集了来自415名意大利孕妇和哺乳期妇女的数据。使用Hayes（2013）的SPSS宏对假设进行了测试。

发现

互联网对健康信息的使用与膳食补充剂的使用直接相关。在线社会资本和互联网对健康信息的使用通过自我效能对饮食补充剂的使用产生积极影响。但是，适度调解分析的结果表明，调解效果受教育程度的调节，因此，受教育程度较低的妇女比受教育程度较高的妇女之间的间接关系更强。

实际影响

膳食补充剂营销商和公共卫生机构可以通过互联网和社交媒体传播信息，以及通过增强在线网站上的社会联系来开发和实施膳食补充剂宣传材料和干预措施。

创意/价值

这项研究的独创性在于使用IMB模型作为理论框架来检验自我效能的中介作用和教育在解释在线社会资本和互联网用于健康信息如何影响膳食补充剂的机制方面的调节作用。用法。
