Summary<\/h2>\n\n\n\n

Background<\/h3>\n\n\n\n

Low birthweight (LBW; <2500 g) is an important predictor of health outcomes throughout the life course. We aimed to update country, regional, and global estimates of LBW prevalence for 2020, with trends from 2000, to assess progress towards global targets to reduce LBW by 30% by 2030.<\/p>\n\n\n\n

Methods<\/h3>\n\n\n\n

For this systematic analysis, we searched population-based, nationally representative data on LBW from Jan 1, 2000, to Dec 31, 2020. Using 2042 administrative and survey datapoints from 158 countries and areas, we developed a Bayesian hierarchical regression model incorporating country-specific intercepts, time-varying covariates, non-linear time trends, and bias adjustments based on data quality. We also provided novel estimates by birthweight subgroups.<\/p>\n\n\n\n

Findings<\/h3>\n\n\n\n

An estimated 19\u00b78 million (95% credible interval 18\u00b74\u201321\u00b77 million) or 14\u00b77% (13\u00b77\u201316\u00b71) of liveborn newborns were LBW worldwide in 2020, compared with 22\u00b71 million (20\u00b77\u201323\u00b79 million) and 16\u00b76% (15\u00b75\u201317\u00b79) in 2000\u2014an absolute reduction of 1\u00b79 percentage points between 2000 and 2020. Using 2012 as the baseline, as this is when the Global Nutrition Target began, the estimated average annual rate of reduction from 2012 to 2020 was 0\u00b73% worldwide, 0\u00b785% in southern Asia, and 0\u00b759% in sub-Saharan Africa. Nearly three-quarters of LBW births in 2020 occurred in these two regions: of 19\u2009833\u2009900 estimated LBW births worldwide, 8\u2009817\u2009000 (44\u00b75%) were in southern Asia and 5\u2009381\u2009300 (27\u00b71%) were in sub-Saharan Africa. Of 945\u2009300 estimated LBW births in northern America, Australia and New Zealand, central Asia, and Europe, approximately 35\u00b70% (323\u2009700) weighed less than 2000 g: 5\u00b78% (95% CI 5\u00b72\u20136\u00b74; 54\u2009800 [95% CI 49\u2009400\u201360\u2009800]) weighed less than 1000 g, 9\u00b70% (8\u00b77\u20139\u00b74; 85\u2009400 [82\u2009000\u201388\u2009900]) weighed between 1000 g and 1499 g, and 19\u00b74% (19\u00b70\u201319\u00b78; 183\u2009500 [180\u2009000\u2013187\u2009000]) weighed between 1500 g and 1999 g.<\/p>\n\n\n\n

Interpretation<\/h3>\n\n\n\n

Insufficient progress has occurred over the past two decades to meet the Global Nutrition Target of a 30% reduction in LBW between 2012 and 2030. Accelerating progress requires investments throughout the lifecycle focused on primary prevention, especially for adolescent girls and women living in the most affected countries. With increasing numbers of births in facilities and advancing electronic information systems, improvements in the quality and availability of administrative LBW data are also achievable.<\/p>\n\n\n\n
