Abstract
Objectives
To assess the nutritional and infection status of rural schoolchildren and to study the relationship of infection status with serum 25(OH)D concentrations.
Methods
This study was carried out in a primary school, in a rural setting, near Pune (18°N), Maharashtra. Data collected from 387 children included anthropometric, clinical, infection-related data (using a validated questionnaire) and dietary data (by 24-h recall method over 3 non-consecutive days, including a holiday) and serum 25(OH)D estimations (by ELISA).
Results
Prevalence of underweight and stunting were 18% and 11% respectively. Upper respiratory tract infection (URTI) related symptoms were commonly reported. Episodes of URTI were found to be significantly and negatively correlated with serum 25(OH)D concentrations (rs = −0.14, p < 0.05) and lesser URTI episodes and duration were reported by children who were vitamin D sufficient as compared to those who were insufficient. No association of total infections was found with vitamin D status.
Conclusions
Moderate prevalence of underweight and stunting and frequent URTIs were observed in this population. Higher serum 25(OH)D concentrations and vitamin D sufficiency may be important for prevention of upper respiratory tract infections in rural children.
