Insights
In Iran's hot climate, about one-third of infants are dehydrated during weaning. Prioritizing water supplementation is crucial for infant hydration and preventing dehydration risks.
Area of Science:
- Pediatrics
- Environmental Health
- Nutrition
Background:
- Infant hydration is critical, especially during the weaning period.
- Dry and hot climates pose unique challenges to maintaining adequate fluid balance in infants.
- Understanding hydration status in infants in arid regions is essential for public health.
Purpose of the Study:
- To assess the hydration status of infants aged 4-6 months during the weaning period.
- To investigate the prevalence of dehydration in infants living in a dry and hot climate in central Iran.
- To explore potential contributing factors such as diet and air conditioning use.
Main Methods:
- A cross-sectional study involving 400 infants (4-6 months old) in Yazd, Iran.
- Urine specific gravity (USG) was measured using a refractometer.
- Mothers completed questionnaires regarding infant diet and home air conditioning systems.
Main Results:
- 31% of infants exhibited signs of dehydration (USG >1.020).
- Infant dehydration was more prevalent during the summer months.
- 27% of infants started solid foods without adequate water supplementation, showing significant dehydration.
Conclusions:
- Approximately one-third of infants in central Iran face dehydration risk during weaning.
- Healthcare providers should emphasize the importance of water supplementation when safe.
- Early intervention and education on hydration are vital for infant health in arid regions.
Objective:
To investigate the state of hydration in infants during the weaning period in dry and hot climates in the center of Iran.
Methods:
Using a refractometer, 162 urine specific gravity (USG) was measured from 400 infants, between 4 to 6 months old. They were chosen among infants who visited the primary clinics in the city of Yazd, Iran for routine vaccination during the summer and winter of 2005. A questionnaire was filled out on air conditioning system and diet from mothers. A USG >1.020 was accepted as dehydrated, and a USG <1.010 as well hydrated.
Results:
Thirty-one percent of the infants were dehydrated, and 34% were well hydrated, infants were more dehydrated in summer (p<0.05). Twenty-seven percent of them started solid food without water supplementation, and dehydration was significant in most of them (p<0.05). We could not determine which type of air conditioning devices now used at home affect water status, but there was a trend toward dehydration in those using both fan and cooler (p=0.096).
Conclusion:
In the desert area in the center of Iran, during weaning, approximately one third of the infants are exposed to the danger of dehydration. Our primary health care provider should consider the priority of water during weaning when water supplementation is safe.
