Abstract

Background

The triadic relationship among the number of NCDs, preventive behaviors and health beliefs has not been fully explored, especially the role of health beliefs.

Aims

To explore the association between the number of NCDs and preventive behaviors, as well as the mediating effect of health beliefs and its dimensions among middle-aged and older adults. Provide scientific evidence for developing targeted behavior intervention.

Methods

Data from 2095 middle-aged and older adults who completed demographic information, health beliefs and preventive behaviors questionnaire. Mediation analysis was used to explore the association of health beliefs and its dimensions between the number of NCDs and preventive behaviors.

Results

Health beliefs and self-efficacy positively impacted preventive behaviors, whereas perceived severity, while perceived barriers had negative effects. Health beliefs (β = − 0.1809, 95% CI − 0.2658 to − 0.0960) and its dimensions(Perceived barriers:β = − 0.0881, 95% CI − 0.1533 to − 0.0232, self-efficacy: β = − 0.2706, 95% CI − 0.3592 to − 0.1892) partially mediated the associations between the number of NCDs and preventive behaviors. The negative mediation effects indicates that as the number of NCDs increases, preventive behaviors decrease, partly due to a decline in health beliefs and self-efficacy, as well as an increase in perceived barriers (scored inversely, meaning higher barriers). These mediation pathways exhibited modest strength, highlighting the importance of health beliefs on behavior change.

Conclusions

An increasing number of NCDs is associated with reduced engagement in preventive behaviors. Health beliefs and its dimensions play a partial mediating role in this relationship. Effective intervention targeting health beliefs may help promote positive behavioral changes.

健康信念在中国南方中老年人非传染性疾病数量与预防行为之间的关联中起中介作用
非传染性疾病数量、预防行为和健康信念三者之间的三位一体关系尚未得到充分的探讨,尤其是健康信念的作用。目的探讨中老年人非传染性疾病数量与预防行为的关系,以及健康信念及其维度的中介作用。为制定针对性行为干预提供科学依据。方法对2095名中老年人进行人口统计、健康信念和预防行为问卷调查。采用中介分析探讨非传染性疾病数量与预防行为之间的健康信念及其维度的关联。结果健康信念和自我效能对预防行为有正向影响,而感知严重性和感知障碍对预防行为有负向影响。健康信念(β = - 0.1809, 95% CI为- 0.2658至- 0.0960)及其维度(感知障碍:β = - 0.0881, 95% CI为- 0.1533至- 0.0232,自我效能:β = - 0.2706, 95% CI为- 0.3592至- 0.1892)部分介导了非传染性疾病数量与预防行为之间的关联。负面中介效应表明,随着非传染性疾病数量的增加,预防行为减少,部分原因是健康信念和自我效能的下降,以及感知障碍的增加(得分相反,意味着更高的障碍)。这些中介途径表现出适度的强度,突出了健康信念对行为改变的重要性。结论非传染性疾病数量的增加与预防行为参与的减少有关。健康信念及其维度在这一关系中起部分中介作用。针对健康信念的有效干预可能有助于促进积极的行为改变。
