Summary
This summary is machine-generated.Preschool interventions combining physical activity and nutrition show modest benefits for obese children, improving BMI and behaviors. Early intervention in schools is key for lifelong healthy habits.
Area Of Science
- Pediatrics
- Public Health
- Nutrition Science
Background
- Childhood obesity is a growing concern, with preschool years being a critical period for intervention.
- Obesity in early childhood significantly increases the risk of adult obesity and associated health issues.
- Evidence for combined physical activity and nutrition programs in preschool settings is limited.
Purpose Of The Study
- To systematically review the impact of combined physical activity and nutrition interventions in obese preschoolers.
- To evaluate the effectiveness of school-based programs integrating these interventions.
Main Methods
- Systematic literature search across five major databases up to August 31, 2025.
- Inclusion of randomized controlled trials (RCTs) focusing on combined in-preschool physical activity and nutrition interventions.
- Assessment of methodological quality using the RoB-2 scale; systematic review registered in PROSPERO.
Main Results
- Combined interventions demonstrated modest but consistent improvements in Body Mass Index (BMI) for obese preschoolers.
- Positive effects were observed in dietary habits and behavioral outcomes.
- Family involvement and school environmental modifications enhanced intervention effectiveness.
Conclusions
- Preschool-based combined physical activity and nutrition interventions offer benefits for obese children.
- The preschool years represent a critical window for effective obesity prevention strategies.
- Future research should focus on standardized outcomes, longer follow-up, and cost-effectiveness for scalability.

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...
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
The collective bacteria residing in and around plant roots are termed the rhizosphere. These soil-dwelling bacterial species are incredibly diverse....
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.
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.
Percentiles are a type of fractile that partition data into...
