Insights

Low birth weight (LBW) affects 8.8% of newborns in Yazd, Iran. Preterm labor, working mothers, and pregnancy-induced hypertension are key risk factors for LBW.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Health
  • Public Health Research

Background:

  • Low birth weight (LBW) is a critical global health issue, contributing significantly to neonatal mortality in both developed and developing nations.
  • Identifying regional prevalence and risk factors for LBW is crucial for targeted public health interventions.

Purpose of the Study:

  • To determine the prevalence of low birth weight (LBW) in Yazd, Iran.
  • To investigate the associated risk factors contributing to LBW in this population.

Main Methods:

  • A cross-sectional study design was employed, analyzing data from all registered births in Yazd maternity hospitals in 2008.
  • Comparison was made between low birth weight neonates and those with birth weights exceeding 2,500 grams.

Main Results:

  • The overall prevalence of LBW in Yazd was found to be 8.8%.
  • Univariate analysis identified first/second pregnancies, teenage pregnancy, maternal diseases (hypertension, UTI), short birth intervals (<3 years), preterm labor, and working mothers as risk factors.
  • Multivariate analysis confirmed preterm labor (OR 5.2), working mothers (OR 2.7), and pregnancy-induced hypertension (OR 1.5) as significant risk factors for LBW.

Conclusions:

  • Targeted screening for high-risk pregnancies, including teenage mothers, those with short birth intervals, and pre-existing maternal conditions, is essential.
  • Enhanced prenatal care and improved healthcare facilities are vital strategies to mitigate the incidence of LBW.

z Scores and Area Under the Curve01:17

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of zero.
Factors Affecting Illness01:18

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,...
Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health condition at a...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
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...
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.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...
