Summary
Dietary patterns, not single nutrients, are linked to frailty. A healthy diet rich in fruits, vegetables, and whole grains may reduce frailty risk.
Area of Science:
- Gerontology
- Nutritional Science
- Epidemiology
Background:
- Assessing single nutrients overlooks crucial nutrient interactions.
- Dietary patterns are increasingly recognized for their association with frailty.
Purpose of the Study:
- To systematically review and meta-analyze the association between dietary patterns and frailty.
Main Methods:
- Searched PubMed, Scopus, and Google Scholar for epidemiological studies up to April 2018.
- Included cohort or cross-sectional studies on dietary patterns and frailty risk, excluding single nutrient/food analyses.
- Employed random-effects models for meta-analysis and trim and fill analysis for publication bias.
Main Results:
- Included 13 studies (15 effect sizes), with 9 cohort/cross-sectional studies in the meta-analysis.
- Higher adherence to healthy dietary patterns showed significantly lower odds of frailty (OR=0.69, 95% CI: 0.57-0.84).
Conclusions:
- A diet abundant in fruits, vegetables, and whole grains may lower frailty risk.
- Further longitudinal research is recommended to solidify the link between dietary patterns and frailty.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

14.7K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

01:09Directing Effect of Substituents: meta-Directing Groups
5.9K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
