Insights

Subclinical vitamin A deficiency affects 35.7% of children under 6 in Nagpur slums. Female gender, undernutrition, and measles are key risk factors, highlighting the need for targeted interventions to prevent this deficiency.

Area of Science:

  • Public Health
  • Nutritional Epidemiology
  • Pediatrics

Background:

  • Subclinical vitamin A deficiency is a significant public health concern in developing countries.
  • Early identification of risk factors is crucial for effective prevention strategies in vulnerable populations.

Purpose of the Study:

  • To investigate the prevalence and risk factors associated with subclinical vitamin A deficiency.
  • To identify key determinants for targeted public health interventions in urban slums.

Main Methods:

  • A cross-sectional study involving 308 non-xerophthalmic children under 6 years.
  • Conjunctival impression cytology was used to assess vitamin A status.
  • Univariate and logistic regression analyses were performed to identify risk factors.

Main Results:

  • The prevalence of subclinical vitamin A deficiency was found to be 35.7%.
  • Significant risk factors identified included female gender, illiterate mothers, lower socioeconomic status, multiple young children, undernutrition, diarrhea, measles, and acute respiratory infections.
  • Logistic regression highlighted female gender, multiple young children, undernutrition, and measles as significant predictors.

Conclusions:

  • Subclinical vitamin A deficiency is highly prevalent in the studied urban slum population.
  • Female children, those with undernutrition, and a history of measles are at increased risk.
  • Findings underscore the importance of addressing socioeconomic, nutritional, and infectious disease factors for prevention.

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

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 in our...
