Insights
Subclinical vitamin A deficiency affects 35.7% of children under 6 in Nagpur slums. Female gender, undernutrition, and measles are key risk factors, highlighting the need for targeted interventions to prevent this deficiency.
Area of Science:
- Public Health
- Nutritional Epidemiology
- Pediatrics
Background:
- Subclinical vitamin A deficiency is a significant public health concern in developing countries.
- Early identification of risk factors is crucial for effective prevention strategies in vulnerable populations.
Purpose of the Study:
- To investigate the prevalence and risk factors associated with subclinical vitamin A deficiency.
- To identify key determinants for targeted public health interventions in urban slums.
Main Methods:
- A cross-sectional study involving 308 non-xerophthalmic children under 6 years.
- Conjunctival impression cytology was used to assess vitamin A status.
- Univariate and logistic regression analyses were performed to identify risk factors.
Main Results:
- The prevalence of subclinical vitamin A deficiency was found to be 35.7%.
- Significant risk factors identified included female gender, illiterate mothers, lower socioeconomic status, multiple young children, undernutrition, diarrhea, measles, and acute respiratory infections.
- Logistic regression highlighted female gender, multiple young children, undernutrition, and measles as significant predictors.
Conclusions:
- Subclinical vitamin A deficiency is highly prevalent in the studied urban slum population.
- Female children, those with undernutrition, and a history of measles are at increased risk.
- Findings underscore the importance of addressing socioeconomic, nutritional, and infectious disease factors for prevention.
Abstract:
The present study was carried out to investigate risk factors for subclinical vitamin A deficiency in children under 6 years of age in the urban slums of Nagpur, India. The study included 308 nonxerophthalmic children selected randomly from the study population. On the basis of conjunctival impression cytology the prevalence of subclinical vitamin A deficiency was estimated to be 35.7 per cent. The current study recognised a significant association between female gender, illiterate mother, lower socioeconomic status, more than two children under 5 years of age at home, undernutrition, history of diarrhoea, measles, acute respiratory infections, and subclinical vitamin A deficiency on univariate analysis. Logistic regression analysis identified significance of female gender, more than two children under 5 years of age at home, undernutrition, and measles in the outcome of subclinical vitamin A deficiency. Estimates of attributable risk proportions and population attributable risk proportions for significant and preventable risk factors confirmed their etiological and preventable role in subclinical vitamin A deficiency respectively.
