157998 Low-birthweight babies (% of births)   Low-birthweight babies are newborns weighing less than 2,500 grams, with the measurement taken within the first hour of life, before significant postnatal weight loss has occurred. Statistical concept and methodology: Model methods are used based on availability of country input data. Country input data included: (i) estimates from administrative sources representing =90 per cent of live births labelled as high coverage; (ii) estimates from administrative sources representing 80 to <90 per cent of live births labelled as medium coverage; and (iii) estimates from household surveys adjusted for missing birthweights and heaping. The model methods applied were: b-spline: data for countries with =8 data points from high coverage administrative sources with =1 prior to 2005 and =1 more recent than 2010, were smoothed with b-spline regression to generate annual LBW prevalence estimates that followed country-reported estimates very closely. Hierarchical regression: data for countries not meeting requirements for b-spline but with =1 LBW country input data point were fitted into a model using a set of covariates to generate annual LBW prevalence estimates. The covariates included the natural log of neonatal mortality rate; the proportion of children underweight (weight for-age z score below minus two standard deviations from median weight for age of reference population); data type (high coverage administrative, low coverage administrative, household survey); UN region (e.g., Southern Asia, Caribbean); and a country-specific random effect.). These estimates may vary substantially from those reported by countries. Partial data: the estimate is based on only partial data for the most recent survey, therefore modelled estimates not shown for the individual country.
