Insights

Accelerated early growth in children from high-risk pregnancies is linked to increased childhood adiposity. Promoting breastfeeding and reducing cesarean births may support healthier postnatal growth.

Area of Science:

  • Pediatrics
  • Public Health
  • Maternal-Fetal Medicine

Background:

  • Early childhood growth patterns are linked to later adiposity.
  • The influence of lifestyle factors on this association, particularly in high-risk pregnancies, requires further investigation.

Purpose of the Study:

  • To examine the relationship between growth profiles in children born to mothers with high-risk pregnancies and their adiposity at age 5.
  • To assess the impact of lifestyle and antenatal/postnatal exposures on this association.

Main Methods:

  • Prospective cohort study of 609 children from the Finnish Gestational Diabetes Prevention Study (RADIEL).
  • Latent class mixed models were used to identify growth profiles based on ponderal index.
  • Adiposity was measured using anthropometrics and body composition analysis at age 5.

Main Results:

  • Three growth profiles were identified: ascending, intermediate, and descending.
  • Children with ascending growth profiles exhibited higher body fat percentage, ISO-BMI, and waist circumference at age 5.
  • Ascending and intermediate growth profiles were associated with higher adiposity, even after adjusting for lifestyle factors and prepregnancy BMI. Meeting lifestyle intervention goals and exclusive breastfeeding for 3+ months were associated with lower odds of ascending growth.

Conclusions:

  • Accelerated early growth in children from high-risk pregnancies is associated with increased adiposity at age 5.
  • Lifestyle factors did not fully explain this association.
  • Recommendations include promoting breastfeeding and reducing cesarean deliveries to potentially improve postnatal growth outcomes.

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Obesity01:24

Obesity

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...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution01:25

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
