Abstract

Pneumonia is the leading infectious cause of morbidity and mortality in young children in Bangladesh. We present the epidemiology of pneumonia in Bangladeshi children <5 years before 10-valent pneumococcal conjugate vaccine introduction and investigate factors associated with disease severity and mortality. Children aged 2-59 months admitted to three Bangladeshi hospitals with pneumonia (i.e., cough or difficulty breathing and age-specific tachypnea without danger signs) or severe pneumonia (i.e., cough or difficulty breathing and ≥1 danger signs) were included. Demographic, clinical, laboratory, and vaccine history data were collected. We assessed associations between characteristics and pneumonia severity and mortality using multivariable logistic regression. Among 3639 Bangladeshi children with pneumonia, 61% had severe disease, and 2% died. Factors independently associated with severe pneumonia included ages 2-5 months (adjusted odds ratio [aOR] 1.60 [95% CI: 1.26-2.01]) and 6-11 months (aOR 1.31 [1.10-1.56]) relative to 12-59 months, low weight for age (aOR 1.22 [1.04-1.42]), unsafe drinking water source (aOR 2.00 [1.50-2.69]), higher paternal education (aOR 1.34 [1.15-1.57]), higher maternal education (aOR 0.74 [0.64-0.87]), and being fully vaccinated for age with pentavalent vaccination (aOR 0.64 [0.51-0.82]). Increased risk of pneumonia mortality was associated with age <12 months, low weight for age, unsafe drinking water source, lower paternal education, disease severity, and having ≥1 co-morbid condition. Modifiable factors for severe pneumonia and mortality included low weight for age and access to safe drinking water. Improving vaccination status could decrease disease severity.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 December 2016.
All research outputs
#6,681,619
of 8,769,477 outputs
Outputs from BMC Public Health
#6,175
of 7,191 outputs
Outputs of similar age
#209,019
of 300,094 outputs
Outputs of similar age from BMC Public Health
#168
of 205 outputs
Altmetric has tracked 8,769,477 research outputs across all sources so far. This one is in the 13th percentile – i.e., 13% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,191 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.3. This one is in the 6th percentile – i.e., 6% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 300,094 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 205 others from the same source and published within six weeks on either side of this one. This one is in the 6th percentile – i.e., 6% of its contemporaries scored the same or lower than it.
