Abstract

Context: Although maternal stature has been associated with offspring mortality and health, the extent to which this association is universal across developing countries is unclear.

Objective: To examine the association between maternal stature and offspring mortality, underweight, stunting, and wasting in infancy and early childhood in 54 low- to middle-income countries.

Design, setting, and participants: Analysis of 109 Demographic and Health Surveys in 54 countries conducted between 1991 and 2008. Study population consisted of a nationally representative cross-sectional sample of children aged 0 to 59 months born to mothers aged 15 to 49 years. Sample sizes were 2,661,519 (mortality), 587,096 (underweight), 558,347 (stunting), and 568,609 (wasting) children.

Main outcome measures: Likelihood of mortality, underweight, stunting, or wasting in children younger than 5 years.

Results: The mean response rate across surveys in the mortality data set was 92.8%. In adjusted models, a 1-cm increase in maternal height was associated with a decreased risk of child mortality (absolute risk difference [ARD], 0.0014; relative risk [RR], 0.988; 95% confidence interval [CI], 0.987-0.988), underweight (ARD, 0.0068; RR, 0.968; 95% CI, 0.968-0.969), stunting (ARD, 0.0126; RR, 0.968; 95% CI, 0.967-0.968), and wasting (ARD, 0.0005; RR, 0.994; 95% CI, 0.993-0.995). Absolute risk of dying among children born to the tallest mothers (> or = 160 cm) was 0.073 (95% CI, 0.072-0.074) and to those born to the shortest mothers (< 145 cm) was 0.128 (95% CI, 0.126-0.130). Country-specific decrease in the risk for child mortality associated with a 1-cm increase in maternal height varied between 0.978 and 1.011, with the decreased risk being statistically significant in 46 of 54 countries (85%) (alpha = .05).

Conclusion: Among 54 low- to middle-income countries, maternal stature was inversely associated with offspring mortality, underweight, and stunting in infancy and childhood.

Box Plots of Relative Risk for the Association Between 1-cm Increase in Maternal Height and Offspring Mortality Among Children by World Bank Income Classification and WHO Regional Classification of Countries WHO, World Health Organization; IQR, interquartile range. Plotted on log scale. For World Bank income classification, low income indicates $975 or less; lower middle income, $976–$3855; upper middle income, $3856–$11 905 (2008) gross national income per capita. Boxes indicate first and third quartiles with median lines; whiskers indicate first quartile minus 1.5 × IQR and third quartile + 1.5 × IQR; all values outside the whiskers are shown as filled circles (outliers).
