Abstract

PURPOSE OF THE RESEARCH

To test whether health literacy is associated with sunlight exposure behavior, we interviewed 648 Chinese adults aged 65 years or older.

METHODS

Using the information-motivation-behavioral skills model and structural equation modeling, we tested whether health literacy was associated with the complex relationships among knowledge about vitamin D, attitudes toward sunlight exposure, doctor recommendations regarding sunlight exposure, and sunlight exposure behavior.

RESULTS

Health literacy was directly associated with sunlight exposure (β=.20, p<.01). Indirect relationships also existed between knowledge and sunlight exposure through health literacy (β=.46, p<.001) and between attitudes and sunlight exposure through health literacy (β=-.12, p<.05). The model had good fit (χ(2)/df=2.79; RMSEA=.053, p=.346; CFI=.95; TLI=.92).

CONCLUSIONS

Health literacy should be considered when educating older adults about vitamin D supplements and sunlight exposure. Providing relevant knowledge or making doctor recommendations might not be effective. Training should focus on individuals with low health literacy who may be less likely to receive sunlight exposure.

摘要

研究目的

为了测试健康素养是否与阳光暴露行为相关，我们对648名65岁及以上的中国成年人进行了访谈。

方法

使用信息-动机-行为技能模型和结构方程模型，我们测试了健康素养是否与维生素D知识、对阳光暴露的态度、医生关于阳光暴露的建议以及阳光暴露行为之间的复杂关系相关。

结果

健康素养与阳光暴露直接相关（β = 0.20，p < 0.01）。通过健康素养，知识与阳光暴露之间也存在间接关系（β = 0.46，p < 0.001），态度与阳光暴露之间也存在间接关系（β = -0.12，p < 0.05）。该模型拟合良好（χ(2)/df = 2.79；RMSEA = 0.053，p = 0.346；CFI = 0.95；TLI = 0.92）。
