Summary
Parents
Area of Science:
- Behavioral Science
- Public Health
- Childhood Obesity Prevention
Background:
- Active commuting to school (ACS) is crucial for children's health.
- Understanding parental influence on ACS is vital for intervention development.
- Existing models may not fully capture the determinants of ACS.
Purpose of the Study:
- To evaluate a modified integrative model (IM) for explaining parental intention and children's ACS.
- To identify key predictors of parents' intention to promote ACS.
- To assess the direct and indirect effects on children's ACS.
Main Methods:
- Survey administered to 857 parents of fourth graders.
- Structural equation modeling used to test the modified IM.
- Model fit assessed using standard indices (RMSEA, CFI, TLI).
Main Results:
- The modified IM showed excellent fit to the data.
- Perceived barriers, self-efficacy, and health beliefs predicted parental intention.
- Parental intention and self-efficacy were significant predictors of children's ACS.
Conclusions:
- The modified IM provides a robust framework for understanding ACS.
- Interventions targeting parental self-efficacy and beliefs can promote ACS.
- This model can guide the design of effective public health initiatives.

Active Transport
2.7K
Active transport is a critical biological process that allows cells to move solutes against an electrochemical gradient. This process requires direct energy input and is characterized by its selectivity, saturability, and susceptibility to competitive inhibition.
Primary active transporters, like Na+, K+ and -ATPase, directly utilize ATP to move ions across the membrane. These transporters play significant roles in various physiological processes. For instance, Na+, K+ and -ATPase maintain...

In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...
