Objective:
to estimate the association between maternal nutritional extremes and offspring mortality in the Brazilian population.
Methods:
this cross-sectional study used secondary data from Brazilian women of reproductive age obtained from the National Demographic and Health Survey 2006. Maternal anthropometric indices were used: height, body mass index (BMI), and waist circumference. Logistic regression modelling was used to evaluate the relationship between obesity and offspring mortality. The data analysis was appropriate for the complex sample design.
Results:
children of mothers of short stature were at greater risk of death in the postnatal period than children of mothers of normal height, even after adjusting for sociodemographic characteristics [odds ratio (OR) 4.54, 95% confidence interval (CI) 1.31-15.77]. Maternal obesity was associated with mortality, and children whose mothers were abdominally obese were at greater risk of dying in the neonatal period (OR 3.19, 95% CI 1.23-8.27). Children of mothers who were overweight or obese (BMI≥25kg/m(2)) were at greater risk of dying in the neonatal period (OR 2.41, 95% CI 1.12-5.16), and children of malnourished mothers (BMI<18.5kg/m(2)) were at greater risk of dying during the postneonatal period (OR 9.47, 95% CI 2.07-43.41).
Conclusion:
maternal obesity is a risk factor for neonatal death, maternal malnutrition is a risk factor for postneonatal death, and maternal short stature is a risk factor for mortality among Brazilian children.

Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
