  abstract = {{B}ackground: {L}ow and high body mass index ({BMI}) are hypothesized to impact offspring neurodevelopment, but less is known in sub-{S}aharan {A}frica where undernutrition is highly prevalent. {O}bjective: {T}he aim of this study was to investigate the association between maternal anthropometric measurements during pregnancy and neurocognitive and behavioral development in children at age 1 and 6 years, in a mother-child cohort from {B}enin. {M}ethods: {T}his prospective cohort study included surviving singletons born to pregnant women in {A}llada, {B}enin. {C}ognitive and motor functions of 747 and 574 children were assessed at 1 and 6 years of age, respectively, in addition to behavioral difficulties and attention deficit and hyperactivity disorders. {S}tatistical analysis using multiple linear regression models tested main associations, potential mediating factors were additionally adjusted for. {R}esults: {T}otal of 17%, 72.5%, 7.7% and 2.5% of women were estimated to be underweight, normal weight, overweight and obese before pregnancy, respectively. {W}omen who were underweight had a higher median weight gain (240 [170-300]) over the course of pregnancy, compared to normal {BMI} women (210 [160-260]), and overweight/obese women (150 [110-240]). {A}fter exclusion of obese women, estimated prepregnancy {BMI} was significantly associated with higher motor scores (0.26, 95% {CI} 0.002-0.53) and cognitive scores (0.37, 95% {CI} 0.02-0.72) after adjustment for confounding factors. {T}here was no association between gestational weight gain and offspring neurodevelopment at 1 and 6 years of age. {T}here was no association between maternal {BMI} and gestational weight gain and behavior and attention deficit and hyperactivity disorders at 6 years of age. {C}onclusions: {O}ur study suggests that low {BMI} before pregnancy may impair short- and long-term neurocognition in children in the {B}eninese context. {U}ndernutrition in childhood has great impact and efforts to adequate prevention for both child and maternal undernutrition should be enforced in low- and middle-income countries.},
