Summary
High ambient temperatures during pregnancy and the first month after birth are linked to rapid infant weight gain. This finding highlights environmental factors influencing early childhood obesity risk.
Area of Science:
- Environmental Health
- Pediatrics
- Epidemiology
Background:
- Childhood obesity is a growing global public health issue.
- Rapid infant weight gain is a known predictor of future overweight and obesity.
- Existing research suggests a link between ambient temperature exposure and infant growth.
Purpose of the Study:
- To investigate the association between prenatal and early postnatal ambient temperature exposure and rapid infant weight gain.
- To quantify the risk of rapid infant weight gain related to temperature exposure during critical developmental periods.
Main Methods:
- A population-based historical cohort study of over 1.1 million infants born between 2011-2019.
- Utilized a spatiotemporal model to estimate ambient temperatures at the infant's residence.
- Employed the SuperImposition by Translation and Rotation (SITAR) method to model infant growth and define rapid weight gain (upper tertile of growth velocity).
Main Results:
- Higher ambient temperatures during pregnancy were associated with increased risk of rapid infant weight gain (RR 1.33 for highest vs. lowest quintile).
- Higher ambient temperatures during the first postnatal month also showed an association with rapid infant weight gain (RR 1.19).
- Specific temperature associations varied by gestational period, with high temperatures linked to early/mid-pregnancy and low temperatures to late pregnancy.
Conclusions:
- Both prenatal and postnatal ambient temperature exposures are significantly associated with rapid infant weight gain.
- Environmental temperature is a modifiable factor that may influence early-life weight trajectories.
- Findings underscore the importance of considering ambient temperature in strategies to prevent childhood obesity.

1.6K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

The Collision Theory
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...

A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

01:30Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
