Insights

Family planning and child spacing are crucial for reducing child mortality in Bangladesh. Contraceptive use and birth intervals significantly decrease neonatal, infant, and under-5 deaths.

Area of Science:

  • Public Health
  • Demography
  • Pediatrics

Background:

  • Child mortality remains a significant public health challenge in low-income countries.
  • Identifying key factors influencing under-5 mortality is essential for effective intervention strategies.

Purpose of the Study:

  • To identify factors associated with mortality in children under 5 years of age.
  • Utilized a nationally representative sample of singleton births in Bangladesh from 2004-2011.

Main Methods:

  • Analysis of pooled Bangladesh Demographic and Health Surveys (2004, 2007, 2011).
  • Included 16,722 singleton live-born infants.
  • Outcome measures: neonatal, postneonatal, infant, child, and under-5 mortality.

Main Results:

  • Significant reductions observed in postneonatal (48%), infant (33%), and under-5 (29%) mortality over the study period.
  • Neonatal and child mortality showed no significant reduction.
  • Mothers using contraception and those with older children (≥3 years) had significantly lower mortality risks.
  • Previous sibling death was associated with significantly higher mortality risks.

Conclusions:

  • Family planning and child spacing interventions are vital for reducing overall under-5 mortality in Bangladesh.
  • Public health initiatives focusing on contraceptive use and optimal birth intervals are recommended.
  • Targeted interventions are needed to address persistent neonatal and child mortality rates.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

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,...

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...

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...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
