In a combined multivariable host-environment model, the risk of TB increased with crowding, exposure to a known TB case, as well as amongst the Jola ethnic group.
Lack of access to health services and to antimicrobial agents for treatment further increases the risk for death from ARI. Risk factors among displaced persons include crowding, exposure to indoor cooking using open flame, and poor nutrition.
We will specifically discuss the effects of housing quality, noise, residential crowding, and exposure to light and natural settings on child- and adult mental health, both in general and more specifically in low-socioeconomic-status environments.
The data collected showed that the high measles mortality depended on crowding, intensive exposure, and dose of infection [ 22].
As such he says he's seen football in Australia transform from a minor sport, where it was like a "school of hard knocks", to one which attracts big crowds and great exposure and provides for its players, giving them a decent living without them having to leave for Europe or elsewhere.
Nonetheless, even between civilian communities, factors such as crowding or continuous exposure, that can be viewed as favouring simultaneous contacts between a susceptible person and infectious ones, were associated to higher mortality rates.
Although these data do not exclude an effect of respiratory viruses on microbiota composition, they do suggest other season-related factors like environmental factors (temperature, humidity, smoke exposure, crowding), or nutrient- or vitamine-related effects, or a combination of factors might be important for the observed shifts in microbiota profiles [3], [16], [20].
Researchers have identified many risk factors for ALRI in young children including low birth weight, lack of breastfeeding, crowded housing conditions, exposure to tobacco smoke, low household income, low maternal educational attainment, day care attendance, and incomplete immunizations [ 1, 8].
Potential postnatal confounding factors such as breast-feeding, household crowding, secondhand smoke exposure, and socioeconomic status have been evaluated in a preliminary study for 90 children from this cohort and did not appreciably affect the associations shown in this study (data not shown).
