Prediction of low birth weight using modified Indian council of medical research antenatal scoring method

Abstract

Objective: To study the prediction of low birth weight (LBW) using modified Indian Council of Medical Research (ICMR) antenatal scoring method.

Method: The present longitudinal study was carried out amongst 1138 pregnant women residing in area covered by Kinaye primary health centre (PHC) in rural Karnataka, India.

Results: Modified ICMR risk scoring revealed that 597 (52.5%) women had a risk score 6–10 (mild risk), 142 (12.5%) women had risk score 11–15 (moderate risk) and 29 (2.5%) had risk score ≥16 (severe risk), whereas, remaining 370 (32.5%) had a score of 0–5 considered as “no risk group”. The incidence of LBW had direct relationship with the risk score. The sensitivity was high (80.6%), whereas, specificity was slightly low (70.4%), positive predictive value was low (43.8%) and negative predictive value high (92.7%) for LBW when the risk score cut-off point was >7.

Conclusion: The modified ICMR antenatal scoring method can be used at all levels of health care and is an ideal instrument for prediction of LBW at the community level. It can be easily applied by even a health worker, not time consuming and at the same time does not lose its predictability.
