Table 5 Results of multiple linear regression analysis using the outcome variable infant mortality rate

From: Diet and mortality rates in Sub-Saharan Africa: Stages in the nutrition transition

Outcome: Infant Mortality Rate
  β Coefficient Standard Error P-value 95% confidence interval
Underweight-for-age* 1.03 0.41 0.020 0.17-1.89
Protein** -1.12 0.27 0.001 -1.67-(-0.56)
Exclusively Breastfed* -0.55 -3.27 0.003 -0.90-(-0.21)
Constant 139.66 21.45 0.001 95.97-183.36
Interpretation     
Underweight-for-Age* For every 1% increase in the number of children underweight-for-age, the infant mortality rate increases by 1 death per 1000 infants
Protein For every 1 g increase in protein/capita/day, the infant mortality rate decreases by 1 death per 1000 infants
Exclusively Breastfed* For every 1% increase in the number of infants that are exclusively breastfed for 6 months, the infant mortality rate decreases by 0.5 deaths per 1000 infants
  1. * Indicates measurement in percentage
  2. Indicates measurement in grams/capita/day
