Insights

Low birth weight (LBW) affects 7.2% of neonates in Shahroud, Iran. Key risk factors for LBW include prematurity and high-risk pregnancies, with maternal age showing a protective effect.

Area of Science:

  • Neonatal Health
  • Maternal-Fetal Medicine
  • Public Health

Background:

  • Low birth weight (LBW) is a significant global health concern, associated with increased neonatal morbidity and mortality.
  • Understanding regional prevalence and risk factors is crucial for targeted interventions.

Purpose of the Study:

  • To determine the prevalence of low birth weight (LBW) in neonates in Shahroud, Iran.
  • To identify significant risk factors associated with LBW in this population.

Main Methods:

  • A random sample of 1000 neonates was analyzed.
  • Univariate and multivariate logistic regression models were employed to assess risk factors.
  • Comparison was made between LBW infants and normal birth weight infants.

Main Results:

  • The prevalence of LBW was found to be 7.2%.
  • Prematurity (OR: 42.82) and high-risk pregnancy (OR: 2.76) were significantly associated with LBW.
  • Maternal age over 35 showed a protective association (OR: 0.2) against LBW compared to the 19-35 age group.

Conclusions:

  • Prematurity and high-risk pregnancy are the most critical risk factors for LBW in the studied population.
  • Maternal age demonstrates a reverse association with LBW, suggesting a protective effect in older mothers.
  • Findings highlight the need for focused antenatal care and management of high-risk pregnancies to reduce LBW rates.

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.

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...

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Bulimia Nervosa01:30

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
