Insights

Low birth weight (LBW) is a significant health concern. This study identified key maternal and infant factors linked to LBW in Iran, offering insights for prevention strategies.

Area of Science:

  • Public Health
  • Neonatal Medicine
  • Epidemiology

Background:

  • Low birth weight (LBW) is a critical indicator of neonatal health and a major contributor to infant mortality.
  • Identifying associated maternal and infant factors is crucial for developing effective public health interventions.

Purpose of the Study:

  • To systematically review and meta-analyze the relationship between maternal and infant factors and LBW in Iran.

Main Methods:

  • A systematic review and meta-analysis of published research conducted in Iran.
  • Comprehensive literature search across multiple databases (SID, Madlib, Iranmedex, Irandoc, Google Scholar, PubMed, ISI, Scopus, Magiran).
  • Data synthesis using SPSS 20 and STATA software.

Main Results:

  • Analysis of 25 relevant articles identified significant associations.
  • Gestational age (less than 37 weeks) showed the strongest association with LBW (OR: 19.81).
  • Prenatal care had the least effect (OR: 1.5).

Conclusions:

  • Significant relationships exist between LBW and multiple births, pre-eclampsia, maternal weight gain, infant gender, and maternal age.
  • Controlling these identified factors during pregnancy can help reduce the incidence of LBW.

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...

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...

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,...

Parenting Styles01:27

Parenting Styles

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
Authoritative...

Socioemotional Experience and Gender Development01:30

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...

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,...
