Insights

The burden of nutritional deficiencies in Chinese children under 5 decreased significantly from 1990 to 2015. Despite this progress, regional disparities and specific deficiencies like iron deficiency anemia persist.

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Nutritional deficiencies pose a significant threat to child health globally.
  • Understanding the burden and trends of these deficiencies is crucial for effective public health interventions.

Purpose of the Study:

  • To quantify and describe the distribution and trends of nutritional deficiency burden in Chinese children under 5 years old from 1990 to 2015.

Main Methods:

  • Utilized subnational data from China (33 provinces) from the Global Burden of Disease Study 2015.
  • Employed descriptive epidemiology to analyze prevalence, mortality, and disability-adjusted life year (DALY) rates by sex, time, and location.
  • Examined temporal trends in nutritional deficiencies among children under 5 since 1990.

Main Results:

  • In 2015, the prevalence of nutritional deficiencies was 17.26%, with a DALY rate of 776.26 per 100,000 children.
  • The DALY rate declined by 71.42% from 1990 to 2015, with decreases observed across all regions (Eastern, Central, Western).
  • Protein-energy malnutrition and iron deficiency anemia were the most significant deficiencies; iron deficiency anemia's DALY rate decreased by 15.68%.

Conclusions:

  • The disease burden from nutritional deficiencies in Chinese children under 5 showed a downtrend between 1990 and 2015.
  • Regional variations in disease burden distribution and common nutritional deficiencies persist.
  • Targeted interventions are needed to address remaining disparities and specific deficiencies.

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Anorexia Nervosa01:28

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...
