Insights

Maternal size influences childhood physical activity energy expenditure (PAEE), but birth weight does not. Higher PAEE in children is linked to lower fasting glucose levels.

Area of Science:

  • Pediatric Health
  • Human Physiology
  • Public Health

Background:

  • Maternal size during pregnancy and birth size may influence childhood physical activity energy expenditure (PAEE).
  • Childhood PAEE is hypothesized to be inversely related to adiposity and cardiovascular risk factors.

Purpose of the Study:

  • To investigate the relationship between maternal size and birth size with childhood PAEE.
  • To examine the association between childhood PAEE, body composition, and cardiovascular risk factors.

Main Methods:

  • Longitudinal observational study of 569 Afro-Jamaican mother-offspring pairs.
  • Measurements included anthropometry, bioelectrical impedance, PAEE, and cardiovascular risk factors in children at a mean age of 13.2 years.

Main Results:

  • Maternal weight positively correlated with child's PAEE and body composition (fat-free mass, fat mass, % fat).
  • Childhood PAEE was not significantly associated with birth weight.
  • PAEE showed inverse association with fasting glucose concentration after adjusting for covariates.

Conclusions:

  • Maternal size, not birth weight, is a determinant of childhood PAEE.
  • Childhood PAEE is not strongly associated with body composition but is inversely related to fasting glucose concentration.

Factors Affecting Activity Coefficient01:17

Factors Affecting Activity Coefficient

The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size. 
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a decrease in the...
Energy Balance01:19

Energy Balance

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Lifestyle Factors and Health

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...
Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
Surveys02:16

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
Energy Budgets and Reproductive Strategies00:51

Energy Budgets and Reproductive Strategies

Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
