Increased risk of xerophthalmia following diarrhea and respiratory disease
Insights
In Indonesian preschool children, respiratory illness and diarrhea significantly increased the risk of developing xerophthalmia (vitamin A deficiency). These conditions create a harmful cycle impacting both eye and overall health.
Area of Science:
- Public Health
- Ophthalmology
- Pediatrics
Background:
- Xerophthalmia remains a significant public health concern in developing nations.
- Infections, particularly diarrhea and respiratory diseases, are common in preschool-aged children in rural Indonesia.
- The interplay between nutritional status and infection in the development of xerophthalmia requires further elucidation.
Purpose of the Study:
- To investigate the association between common childhood illnesses and the incidence of xerophthalmia in rural Indonesian preschool children.
- To determine if respiratory disease and diarrhea independently predict xerophthalmia development.
- To explore the potential for a cyclical relationship between infection and vitamin A deficiency.
Main Methods:
- A longitudinal study design was employed, following preschool-aged children in rural Indonesia over 18 months.
- Children were assessed every 3 months, with an average of 3228 children participating in each follow-up interval.
- Data collected included the presence of xerophthalmia, history of diarrhea, respiratory disease, and anthropometric measurements.
Main Results:
- Children with respiratory disease and/or a recent history of diarrhea exhibited more than double the rate of xerophthalmia compared to healthier children (p < 0.05).
- This increased risk was observed independently of the children's anthropometric status.
- The findings suggest a significant link between specific infections and the development of ocular manifestations of vitamin A deficiency.
Conclusions:
- Respiratory infections and diarrhea are critical risk factors for xerophthalmia in preschool-aged Indonesian children.
- A synergistic relationship likely exists between vitamin A deficiency and infections, creating a detrimental cycle of ocular and systemic illness.
- Public health interventions should address both nutritional status and infection control to prevent xerophthalmia.
Abstract:
Preschool-age rural Indonesian children were reexamined every 3 mo for 18 mo. An average of 3228 were free of xerophthalmia at the examination initiating each of the six, 3-mo follow-up intervals. Children with respiratory disease and/or a recent history of diarrhea at the start of an interval developed xerophthalmia by the end of the interval at more than twice the rate of their healthier peers (p less than 0.05) independent of anthropometric status. It appears that vitamin A deficiency and infections, especially diarrhea and respiratory disease, can establish a vicious cycle that induces and perpetuates ocular and systemic disease.
