Diet is a key variable in age-related disease

Dietary diversity (DD) refers to individuals who do not eat individual nutrients, single meals, or certain food groups, but instead eat meals that consist of a variety of foods with a variety of nutrients

Therefore, this study aimed to examine the changes in DDS and risk of cognitive impairment in Chinese adults aged 65 years and older since 1998, based on an ongoing prospective cohort study in China, the China Longitudinal Healthy Longevity Survey (CLHLS)

During 52,325 person-years of follow-up, a total of 2805 participants with normal cognitive function at baseline developed cognitive impairment, with the highest to high group having the lowest incidence of cognitive impairment (34.

Figure 2 shows the association between groups of absolute DDS changes (extreme decline, moderate decline, stable, moderate improvement, and large improvement) and cognitive impairment

Subgroup analysis

Subgroup analysis

We performed a stratified analysis according to potential risk factors (Table 3)

We performed a stratified analysis according to potential risk factors (Table 3)

In this large population-based cohort study, researchers found that maintaining the highest DDS was associated with a significantly lower risk of cognitive impairment

In this large population-based cohort study, researchers found that maintaining the highest DDS was associated with a significantly lower risk of cognitive impairment
.
Over time, participants with persistently high DDS had a significantly lower risk of cognitive impairment than participants in a pattern of persistently low DDS
.
Those with greatly improved DDS were associated with a reduced risk of cognitive impairment in subsequent years
.
These associations were independent of cognitive impairment risk factors and other dietary factors
.
Those with greatly improved DDS were associated with a reduced risk of cognitive impairment in subsequent years
.

In conclusion, a protective association between maintenance of higher DDS and reduced risk of cognitive impairment was observed in Chinese older adults
.
Conversely, reducing or maintaining low DDS increases the risk of cognitive impairment
