**3.3 Causal relationship "Healthy Dietary and Lifestyle"and "healthy longevity" model**

**Figure 3** shows the causal relationship between "Healthy Dietary and Lifestyle", and "Healthy Longevity" for both sexes. The models fit the data well with the following fit indices: NFI = 0.995, IFI = 0.997, and RMSEA = 0.008. R-squared values also fit well: 19 percent for males and 13 percent for females.

Based on this model, "Healthy and Longevity" were significantly affected by "Healthy Dietary and Lifestyles" for both sexes significantly. And we observed a relatively significant direct effect of the "Healthy Diet and Lifestyles" on "Healthy Longevity", with a 0.48 standardized path coefficient for males and 0.36 for females. In this model, we are not concerned about socioeconomic status and three health dimensions as confounding factors.

If only the causal structure of the two latent variables shown in **Figure 3** is analyzed, the more desirable the latent variables of "Healthy diet and Lifestyle." The more desirable the similarly dependent latent variables, the degree of care required. Then, it will be interpreted that "Healthy longevity," a long survival day with a low degree of care needed, becomes statistically significant.
