Overview: Breakfast may be the most important meal of the day, especially when it comes to maintaining cognitive health. Researchers found that skipping breakfast was associated with an increased risk of cognitive decline in middle-aged and older adults, while maintaining the temporal distribution of energy intake during the day was associated with maintaining cognitive health. help you to

Approximately 55 million people worldwide have dementia and the incidence of dementia is steadily increasing. Especially in low- and middle-income countries, the population is expected to triple by 2050. Dementia not only affects an individual’s quality of life, but also adds a significant economic burden to families and societies.

Epidemiological studies have shown correlations between the temporal distribution of daily energy intake (TPEI) and the risk of various chronic diseases such as diabetes and hypertension. However, evidence for the relationship between TPEI and cognitive function at the population level is relatively lacking.

Previous studies in animal models have shown that disrupted meal timing can cause alterations in hippocampal clock rhythms, thereby affecting cognitive function.

A short-term intervention trial of 96 young adults found that eating four equal-sized meals between 9:00 am and 3:00 pm was associated with better cognitive function than eating two meals between 9:00 am and 3:00 pm. may improve. However, long-term studies on TPEI and cognitive function are lacking.

Dr. Changzheng Yuan and Dr. Dongmei Yu of Zhejiang University recently published a paper. life metabolism It is entitled “Temporal patterns and declines in energy intake and cognitive function: A community-based cohort study in China.”

A total of 3,342 participants were included in this study, based on the China Nutrition Health Survey (CHNS) public database. Participants were middle-aged and elderly (mean age 62) from her nine provinces in China with a baseline age ≥ her 55 years. .

The researchers used: 1) A data-driven k-means algorithm was used to identify six patterns of TPEI. “Snacking a lot” pattern, “Breakfast skipping” pattern.

2) Cognitive function was assessed using a modified telephone interview for cognitive status (TICS-m), including immediate and delayed word recall (20 points), backward counting (2 points), and a serial 7-subtraction test (5 points). Rated. The overall cognitive score ranges from 0 to 27, with higher scores indicating better cognitive function.

3) Correlations between TPEI and cognitive function over 10 years were assessed using a linear mixed model (LMM) and included age, sex, place of residence, total energy, physical activity, smoking status, alcohol consumption, and household income. , education level, and body mass index (BMI).

They found that people with an imbalanced TPEI, especially those with a “skipping breakfast” pattern, had significantly lower long-term cognitive scores than those with an “evenly distributed” pattern. rice field.

Thus, maintaining a balanced TPEI may have potentially positive effects on cognitive health, whereas skipping breakfast significantly increases the risk of cognitive decline in middle-aged and older adults. may increase. In conclusion, this study highlights the importance of optimal His TPEI in cognitive function.

Temporal patterns and declines in energy intake and cognitive function: A community-based cohort study in China

Worldwide, about 55 million people had dementia in 2019, and that number is expected to triple by 2050, especially in low- and middle-income countries. Dietary elements are getting more and more attention.
